Description

The invention relates to a connection socket, for use in a connector, comprising a jacket which extends at least in certain areas along a connection axis and which extends at least in areas in the circumferential direction around the connection axis, a base area which is connected to the jacket or a part of the jacket and which extends at least in regions at right angles to the connection axis, with the base area delimiting the connection socket on one side in the direction of the connection axis. The connection sleeve also includes at least one fastening element, at least one pressure surface, which extends in the radial direction to the connection axis, and at least one undercut, which forms a cavity inside the casing. The invention further relates to a connector with a connection socket, and a fixed double board with at least one connector.

In various engineering applications, panels are applied to an underlying framework to create a surface. The boards can be wooden boards or plastic boards, for example, which have a functional surface facing away from the underlying frame construction. The entire structure serves to provide such a functional interface. Such a functional surface can be, for example, the loading floor of a truck. In this case, the functional surface must be stable and wear-resistant. Another application of a structure, in which panels with a functional surface are attached to a frame construction, is formwork panels, which are used to formwork parts of buildings. In this case, the slabs have a functional surface that must be impervious to liquid concrete material used to construct the building parts. In addition, the functional surface should be easy to separate again from the building parts after the building parts have been produced, for which purpose water- and concrete-repellent properties are required. What these and other applications have in common is that the functional surface is subject to wear during use and must therefore be replaced or renewed from time to time in order to ensure that its properties are maintained. In the prior art, the panels that provide the functional surface are usually separated from the underlying frame construction and completely replaced. This complete replacement is time-consuming and cost-intensive.

The object of the invention is therefore to propose solutions with which the replacement of a functional surface on a plate which is fastened to a frame construction underneath can be exchanged or renewed in a simplified manner.

This object is achieved by a connection socket for use in a connector comprising,

• - a jacket, which extends at least partially along a connection axis and which extends at least partially in the circumferential direction around the connection axis, with a receptacle being arranged inside the jacket,
• - a base area, which is connected to the jacket or is part of the jacket and which extends at least in places at right angles to the connection axis, the bottom area delimiting the connection socket on one side in the direction of the connection axis,
• - at least one fastening element, which is arranged on or in the jacket or on or in the floor area,
• - at least one pressure surface, which extends in the radial direction to the connection axis, the pressure surface forming an end face of the connection bush in the direction of the connection axis or protruding beyond the end surface of the connection bush arranged on the bottom area in the radial direction to the connection axis,
• - at least one undercut, which forms a cavity inside the casing, the undercut being delimited in the direction of the connection axis on two opposite sides by elements of the connection bushing which protrude in the radial direction towards the connection axis and are adjacent to the undercut, and the undercut in some areas in the radial direction towards the Connection axis is open.

A connector socket according to the invention is preferably intended for use in a connector for providing a fixed double plate. The connection socket is a fastening element and a connection element.

The connection socket according to the invention extends along an imaginary connection axis which defines the direction in which the connection socket can be connected to another connection element, for example a connection plug. The connection axis is also the direction in which the connection axis can be separated from another connection element, for example a connection plug. The connection socket includes a casing which delimits the connection socket on the outside. The connection axis is located inside the shell, with the shell extending in the direction of the connection axis. At the same time, the casing surrounds the connection axis, at least in certain areas. The jacket preferably completely encloses the connection axis in the circumferential direction. However, it is also possible for the casing to only partially enclose the connection axis and, in particular, to have interruptions in the circumferential direction. A receptacle is arranged inside the shell, which forms a hollow interior there. The receptacle is provided for receiving another connecting element, which is connected to the connecting axle. The connection socket according to the invention also comprises a base area which is connected to the casing. Alternatively, the bottom area can also be part of the jacket. In any case, the floor area extends at least in areas at right angles to the connection axis. At the same time, the bottom area represents a delimitation of the connection socket, which delimits it on one side, viewed in the direction of the connection axis. The connection socket and/or the jacket is open on the side opposite the base area in the direction of the connection axis. This open side gives access to the receptacle inside the shell. The connection socket also includes at least one fastening element. The fastening element can be designed in different ways. In a simple case, the fastening element can be formed by a fastening opening into which an additional fastening component for fastening the connecting axle is introduced. Alternatively, the fastening element can also be formed by a thread arranged on the connection socket. Furthermore, it is possible that the fastening element is formed by a bolt or pin, which is provided for connection to another component with a press fit. Other embodiments of the fastening element are also possible. The fastening element is intended to fasten the connecting axis to another component, for example a plate or a carrier. The fastening element can be arranged at different positions on the connection socket, for example in or on the casing or in or on the base area. The connection socket according to the invention also includes a pressure surface which extends in the radial direction to the connection axis. An extension in the radial direction to the connection axis is to be understood as meaning that the projection of the pressure surface along the connection axis onto a plane perpendicular to the connection axis projects beyond the connection axis. For this purpose, for example, the pressure surface can be arranged perpendicularly to the connection axis. In addition, however, the pressure surface can also be oriented inclined to the connection axis. In this case, the pressure surface extends with one component perpendicular to the connection axis and with another component parallel to the connection axis. As long as a component of the pressure surface extends perpendicularly, ie radially, to the connection axis, it is defined that the pressure surface extends in the radial direction to the connection axis. The pressure surface at least partially delimits the connection socket in a direction parallel to the connection axis. For example, the pressure surface can form an end face of the connection socket in the direction of the connection axis. Alternatively, the pressure surface can be arranged adjacent to the base area or adjacent to the jacket and protrude in the radial direction beyond the base area and the jacket. Finally, the connection socket according to the invention comprises at least one undercut, which forms a cavity inside the casing. In the direction of the connection axis, the undercut is delimited on two of its opposite sides by other, adjacent elements of the connection socket in such a way that the undercut is not accessible in the direction of the connection axis. The undercut is thus delimited in a direction parallel to the connection axis, in particular delimited by elements of the jacket. In the radial direction to the connection axis, however, the undercut is designed to be open, at least in certain areas. The open side of the undercut is preferably oriented toward the receptacle in the jacket.

The connection socket according to the invention is suitable for taking on two different functions when connecting components, for example panels. On the one hand, the connecting sleeve is suitable for forming part of a two-part connector. Such a connector will be described later. When used in the connector, the connecting sleeve can be reversibly connected to and disconnected from another part of the connector. As a result, a detachable function is given that allows easy replacement of components such as plates. The connecting socket can be used, for example, to releasably fix a panel with a functional surface to a frame structure or a carrier underneath. As a second essential function, the connection socket according to the invention can be used alone, ie without a second part of a Ver binders can be used to fasten a component, for example a panel, to a frame construction or to a support. The connection socket is mechanically connected between the component and the frame construction. This means that the flow of force in such a connection of a component, for example a plate, is guided to the connection socket and from the connection socket via its fastening element to the carrier or to the frame structure. The pressure surface of the connecting bush provides a sufficiently large contact surface between the connecting bush and the component, which leads to a low surface pressure between the two components during attachment. This ensures a long-term stable, material-friendly connection between the connection socket and the component. In this connection, the connection socket is connected to a carrier or a frame construction by its fastening element. With this type of attachment, the connecting bush acts in a similar way to a washer in a screw connection: the connecting bush increases the contact surface over which a component is clamped to a frame structure or a carrier in a force-fitting manner. This enlargement of the contact surface compared to a direct connection via a fastening component, which is arranged between the component and the carrier, significantly increases the security of the connection. The surface pressure of the connection is reduced, which reduces the mechanical stress on the component in the fastening area. By reducing this load, the connection becomes more stable, especially over the long term, even with dynamic loads. What is particularly advantageous about the connection socket according to the invention is the simultaneous provision of a pressure surface and a receptacle with an undercut. These two sub-areas or components of the connecting bush can be used to significantly simplify the replacement of a functional surface on a frame construction underneath. The connection socket enables a load-bearing base plate to be fastened to the frame construction with long-term stability and a simple and easily detachable fastening of a cover plate to the base plate, with the cover plate being able to be provided with a functional surface. The connection socket according to the invention is simple in design and can therefore be produced inexpensively.

In one embodiment of the connection socket, it is provided that at least one insertion surface is provided, which extends in the radial direction to the connection axis and is at least partially inclined to the connection axis and which is oriented towards the side of the connection socket facing away from the bottom area in the direction of the connection axis. In this embodiment, the connection socket has an insertion surface which is provided as an insertion surface for facilitating the insertion of a second part of a connector, for example a connector plug. The insertion surface acts like an insertion bevel. At least one component of the insertion surface extends in the radial direction to the connection axis. In this case, the insertion surface is at least partially inclined to the connection axis and can be oriented, for example, at a 45° angle to the connection axis. The insertion surface can completely enclose the connection axis or can only be arranged in regions around the connection axis in the circumferential direction. The insertion surface is preferably conical or curved.

It is preferably provided that the jacket has a jacket surface oriented away from the connection axis, which is at least partially cylindrical and extends parallel to the connection axis. In this embodiment, the jacket is cylindrical on the outside. This shape enables it to be introduced into a cylindrically shaped recess in a component, for example a plate, which is easy to produce.

In one embodiment it is provided that the jacket has a jacket surface oriented away from the connection axis, which forms the pressure surface, the pressure surface preferably being of conical or spherical design at least in certain areas. In this embodiment, the shell is not cylindrical, at least in some areas, but has a shape that has at least one component that extends radially away from the connection axis and thus forms the pressure surface. For this purpose, the outside of the casing can have the shape of a cone, at least in some areas, the side of which with the smaller diameter is oriented towards the bottom area. In this embodiment, a large printing area is provided. Alternatively, the area of the outer lateral surface configured as a pressure surface can also be curved or spherical, with the diameter of the pressure surface perpendicular to the connection axis being smaller on the side facing the base area than on the side facing away from the base area.

In a further embodiment it is provided that the casing has a casing surface oriented away from the connection axis and the pressure surface projects inwards or outwards over the casing in the radial direction towards the connection axis. In this embodiment, the pressure surface projects radially from a surface of the shell ler direction to the connection axis. In this case, the pressure surface can protrude in the radial direction outwards over the outer surface of the shell or in the radial direction inwards over the inner surface of the shell. In the direction of the connection axis, in other words in the direction of the height of the connection socket, the pressure surface can be arranged at different positions. The inclination of the pressure surface to the connection axis can also be designed differently.

In a further embodiment it is provided that the pressure surface is formed by a surface of the base region which is oriented perpendicularly to the connection axis. In this embodiment, the pressure surface is arranged at the bottom area. The pressure surface can extend over the entire surface of the bottom area pointing away from the receptacle or only over a partial area thereof. The advantage of this embodiment is that the pressure surface has a large surface.

In a further embodiment it is provided that the pressure surface is arranged on a collar, wherein the collar is arranged on an outer surface of the jacket facing away from the connection axis and extends in a direction radially away from the connection axis. In this embodiment, a collar is arranged on the outside of the jacket, on which the pressure surface is located. In this embodiment, the pressure surface is thus outside the outside diameter of the shell. The collar can be arranged, for example, on the side of the jacket facing away from the bottom area. The collar preferably extends completely in the circumferential direction around the connection axis. Alternatively, however, the collar can also be arranged only in regions in the circumferential direction around the connection axis. The collar can, for example, protrude in a range from 1 mm to 20 mm in the radial direction outwards over the outer surface of the jacket.

Furthermore, it is provided that the pressure surface is arranged on a side of the collar facing the base area and is oriented perpendicularly to the connection axis or at an acute angle to the connection axis in a direction away from the base area. In this embodiment the pressure surface is arranged on the lower side of the collar. The pressure surface can be oriented at right angles to the connection axis. In this case, the pressure surface preferably extends perpendicularly to the outer surface of the casing. Alternatively, the pressure surface can also be oriented at an acute angle between zero and 90° to the connection axis. Such a pressure surface oriented at an acute angle to the connection axis is preferably designed conically and has a centering effect during assembly of the connection sleeve in a component, for example a plate, similar to the lower area of the head of a countersunk screw.

It is also possible for the collar to adjoin the jacket on the side thereof which is opposite the bottom area in the direction of the connection axis. In this embodiment, the collar is arranged on the side of the jacket facing away from the bottom area. Alternatively, the collar can also be arranged on the side facing the base area or between the side facing the base area and the side of the jacket facing away from the base area in the direction of the connection axis.

In a further embodiment it is provided that the base area is formed by an end face of the jacket. In this embodiment, the bottom area is part of the casing and is formed by an end face or a partial area of the end face of the casing.

It is also possible for the base area to extend radially from the casing towards the connection axis and limit the accommodation inside the casing. In this embodiment, the bottom area is formed by a partial area of the connecting sleeve that differs from the jacket. The bottom portion extends radially inward from the surrounding shell toward the axis of connection. The base area can completely close the jacket on one side of the connection socket in the direction of the connection axis. Alternatively, openings can also be provided in the bottom area, which extend along the connection axis. In this embodiment, the floor area, together with the jacket, delimits the accommodation inside the jacket.

Cleverly, it is provided that the jacket is designed to be rotationally symmetrical to the connection axis, at least in some areas. In this embodiment, at least a partial area of the casing is shaped and positioned rotationally symmetrically to the connection axis. Such a partial area is particularly stable and at the same time can be produced in a simple manner and can be connected to a connecting plug.

In a preferred embodiment it is provided that the shell is defined by a rectangle, triangle, trapezium or polygon which is spaced apart from the connection axis and which rotates around the connection axis and defines the three-dimensional shell. In this embodiment, the shell is designed to be completely rotationally symmetrical to the connection axis. The mantle can be described by having a cross-section in the form a rectangle, triangle or any other cross-sectional shape is rotated around the connection axis. This rotation defines a three-dimensional body that forms the mantle.

In a further embodiment it is provided that the jacket has a circular inner surface and/or outer surface in a plan view parallel to the connection axis. In this embodiment, the shell is designed as a circular cylinder, which has a likewise circular-cylindrical cavity in its interior. In a plan view parallel to the connection axis, the jacket has a circular cross-section. This gives the receptacle inside the jacket a circular-cylindrical shape. This shape is particularly favorable, since a connection with a connector plug can take place equally in any angular orientation around the connection axis.

Furthermore, it is provided that the base area or an end face of the base area is oriented perpendicularly to the connection axis. Such an orientation of the front surface or another surface on the bottom area can be used as a pressure surface, for example. An orientation perpendicular to the connection axis, when installed, enables particularly uniform pressure transmission between the connection socket and another component, for example a plate.

In a further embodiment it is provided that the fastening element is designed as a fastening opening which penetrates the floor area and is arranged coaxially to the connection axis. In this simple embodiment, the fastening element is formed by an opening which allows a fastening component, for example a screw, to pass through. Positioning this fastening opening coaxially to the connection axis enables a symmetrical transmission of force between the connection socket and an adjacently arranged component, for example a plate.

In a further embodiment it is provided that the fastening element is designed as a fastening opening which penetrates through the casing and in particular extends parallel to the connection axis. In this embodiment, the fastening element designed as a fastening opening is not arranged in the floor area but in the jacket. A plurality of attachment openings are preferably arranged in the jacket at regular intervals around the axis of connection. In this way, it is possible to fasten the connecting sleeve to another component, for example a panel, using a plurality of fastening components. In this embodiment, the base area is preferably formed by an end face of the jacket.

It is optionally provided that the fastening element is designed as a fastening opening and a force introduction surface is arranged adjacent to the fastening element, which is oriented at right angles or at an angle of between 90° and 10° to the direction of extension of the fastening element. In this embodiment, a force introduction surface is arranged adjacent to a fastening element designed as a fastening opening. The shape and orientation of the force introduction surface preferably corresponds to the shape of a head of a fastening component, for example a screw. If a countersunk screw is to be used as the fastening component, the force application surface is oriented in such a way that it lies flat against the conically shaped head of the countersunk screw. If, on the other hand, a screw with a flat head is to be used as the fastening component, the force introduction surface is designed to be planar and extends perpendicularly to the direction in which the fastening opening extends. The base area or the jacket can also be reinforced adjacent to the force introduction surface, for example by an increased wall thickness or by an insert element, for example made of metal. In this way, the power transmission between a fastening component and the connection socket is improved.

In an alternative embodiment it is provided that the fastening element is designed as an external thread, which is arranged on an outer surface of the jacket facing away from the connection axis. In this embodiment, the fastening element is arranged on the outside of the shell. Through an external thread arranged there, the connecting socket can be screwed into a correspondingly shaped internal thread in another component. The advantage of this solution is that no additional fastening component is required. Alternatively, an external thread can also be arranged on a partial area of the base area that protrudes in the direction of the connection axis and can serve as a fastening element.

Furthermore, it is provided that the undercut is arranged on the inside of the jacket oriented towards the connection axis and forms a partial area of the receptacle. The undercut forms part of the receptacle and is arranged in the jacket. The undercut preferably extends in the circumferential direction along the inside of the shell around the joint axis.

In a further embodiment, it is provided that the undercut is arranged between the base area and the end of the jacket facing away from the base area in the direction of the connection axis. In this embodiment, the undercut is arranged between the bottom area and the end of the jacket facing away from the bottom area. The undercut is thus arranged on the outer edge of the receptacle pointing away from the connection axis.

Provision is preferably made for the undercut to have at least one holding surface on its side facing away from the base region in the direction of the connection axis, which is oriented at an acute angle to a plane perpendicular to the connection axis. This holding surface is provided so that in the connection state, in which the connecting socket is connected to a connecting plug, a corresponding mating surface, for example a fixing surface of the connecting plug, rests against the holding surface. The connection socket is fixed to the connection plug via this system of the two surfaces. The retaining surface is a sub-surface of the undercut and is oriented at an acute angle relative to a plane perpendicular to the axis of the connection. The holding surface is located on the side of the undercut facing away from the bottom area. The holding surface is preferably shaped in a manner complementary to a corresponding fixing surface of a connector plug.

In an alternative embodiment it is provided that a connecting projection is provided, which protrudes from the base area in the direction of the connecting axis into the receptacle inside the jacket and the undercut and/or the insertion surface are arranged on this connecting projection. In the previously described embodiments, the undercut and the insertion surface are arranged on, in or directly adjacent to the jacket. In this alternative embodiment, a connecting projection is provided which is surrounded by the jacket and is attached to the base area. This connecting projection is in the recording and is surrounded by this. The connection projection is preferably surrounded by the casing over its entire length. The undercut and/or the insertion surface can be arranged on this connecting projection. For example, the undercut on the connecting projection can be arranged directly adjacent to the base area. Such an undercut is delimited on one side by the bottom area and on an opposite side in the direction of the connection axis by an area of the connection projection protruding in the radial direction towards the connection axis. The insertion surface can be arranged adjacent to such an undercut in the direction of the connection axis. In this alternative embodiment, the two functional areas, the undercut and the insertion surface, are arranged inside the receptacle. In this way, the jacket can be used for other functions, for example as a pressure surface or as a base for the fastening element. Of course, a corresponding connector plug in this alternative embodiment must also be shaped differently from a connector plug used for connection to a connector socket according to one of the embodiments in which the undercut and insertion surface are arranged on the jacket.

It is cleverly provided that the fastening element is designed as a fastening opening and penetrates the connecting projection. In this embodiment, a fastening element designed as a fastening opening runs along the connecting projection. In this embodiment, too, the connection opening is preferably arranged coaxially to the connection axis.

Furthermore, it is provided that the connecting projection is arranged coaxially to the connecting axis. Such a coaxial arrangement means that the functional areas of the undercut and/or insertion surface and the connection axis are in one line. As a result, the flow of force through the connecting socket when connected to a connecting plug is guided over a short distance, making the connection stable and rigid.

In a further embodiment it is provided that the receptacle is arranged in a top view from the direction of the connection axis between the jacket and the connection projection and is in particular annular and encloses the connection projection. Such an annular configuration of the receptacle around the connecting projection makes it easier to bring the connecting socket together with a connecting plug. According to this embodiment, the connection socket is preferably designed to be rotationally symmetrical about the connection axis.

It is advantageously provided that the undercut is open on a side facing the connection axis or on a side facing away from the connection axis. The undercut is at least partially open in the radial direction to the connection axis, in order to allow the insertion of a partial area of a connector plug in the connected state. Depending on the embodiment of the undercut, this be open on its side facing the connection axis, in particular when the undercut is arranged on or in the casing. Alternatively, the undercut can also be designed to be open on its side facing away from the connection axis, in particular in the case when the undercut is arranged on or in a connection projection which extends inside the receptacle.

Cleverly, it is provided that the distance in a direction perpendicular to the connecting axis between the edge of the insertion surface facing away from the base area and the inner surface of the jacket is greater than the distance in a direction perpendicular to the connecting axis between the edge of the insertion surface facing the base area and the inner surface of the mantles These features of the lead-in surface define its slope or orientation. The insertion surface should act like an insertion bevel and make it easier to insert a connector plug into the connector socket. The insertion surface is located at the edge or adjacent to the receptacle. The opening width or the inside diameter of the insertion surface is always larger at its edge facing away from the bottom area than its opening width or inside diameter at its edge facing the bottom area. In this way, the insertion surface is inclined so that its inner diameter decreases toward the bottom portion in a direction parallel to the axis of connection. This guides and thus facilitates the introduction of the connecting plug into the interior of the casing, in particular into the receptacle.

In one embodiment it is provided that the insertion surface is conically, spherically or arched in shape at least in certain areas. Such a shape makes it easier to insert a connector plug into the connector socket and thereby centers the connector plug on the connection axis.

Provision is advantageously made for the insertion surface to run around the connection axis and, in particular, to be ring-shaped in a plan view from the direction of the connection axis. In this embodiment, the insertion surface is closed around the connection axis. This ensures that the insertion surface always comes into contact with an inserted connecting plug, in particular in all possible rotational orientations around the connecting axis. Of course, it is also possible for the insertion surface to be arranged only in regions in the circumferential direction around the connection axis.

In a further embodiment it is provided that the insertion surface and the holding surface of the undercut are arranged adjacent to one another and are connected to one another in particular by a rounded transition area. It is favorable if the insertion surface and the holding surface of the undercut are arranged adjacent to one another or adjacent to one another. A rounded transition area is preferably arranged between the insertion surface and the holding surface. When the connection is made, a connector plug inserted into the connection socket is first guided by the insertion surface, then slides over the rounded transition area and then rests against the holding surface at least in certain areas. With this configuration, the connecting force for establishing the connecting state between the connector socket and the connector plug can be reduced.

Cleverly, it is provided that the holding surface is flat or conical, at least in some areas. In order to ensure a large holding force between the connection socket and a connection plug in the connected state, it is important that the holding surface and a surface, for example a fixing surface, bear against the connection plug over a large area. Such a large-area contact can be achieved particularly well by a flat or conical holding surface. Such a shape of the holding surface can be manufactured in a simple manner.

It is advantageously provided that the connection socket consists of a plastic and is designed in one piece. In this embodiment, the connection socket can be produced simply and inexpensively in large numbers, for example by injection molding. The plastic used for production can be fiber-reinforced in order to achieve greater strength. Of course, the connecting socket can also consist of a different material, for example a metal material.

• - a base that supports the other elements of the connector,
• - at least one bending area, which has at least one elastically deformable bending arm, the bending arm extending from the base parallel to a plug-in axle,

A connector according to the invention comprises a connecting socket and, as a counterpart thereto, a connecting plug which can be reversibly connected to the connecting socket. Reversible is to be understood here as meaning that the connection between the connecting socket and the connecting plug can be made and broken again several times. In doing so, neither the connection socket nor the connection plug is damaged or destroyed. The connector according to the invention can be used, for example, to connect two panels to one another and at the same time to fasten them to a carrier or a frame construction.

The connector plug includes a base which supports the remaining elements of the connector, particularly the flex area. A flexing portion is integral with the base and includes at least one elastically deformable flexing arm. Several bending arms are preferably provided. The flexure arm extends from the base parallel to a thru-axle. A plug-in axle is to be understood here as an imaginary axle that defines a direction in which the connector plug can be inserted into a connector socket and pulled out of it again. The connector plug also includes a flexible interior space that is at least partially enclosed by the flexible area. The bending interior serves to accommodate the elastically deformed bending arm in the connection state. Such elastic deformation of the bending arm occurs when connecting to a female connector, when the male connector and the female connector are connected to each other. The elastic deformation of the bending arm causes a restoring force in the bending arm, which leads to a positive and non-positive connection in the connector. The bending arm has a bending element which is connected to the base and which can be deformed more elastically in a direction radially to the plug-in axle. The bending element is preferably shaped like a bending beam. Furthermore, the bending arm comprises a latching element which is arranged on the side of the bending element facing away from the base. The latching element is preferably not elastically deformed when connected to a connecting socket. In the connection state, the latching element engages at least in some areas in the undercut in the connection socket. The locking element has a projection which protrudes in the radial direction to the plug-in axle over the bending element. This projection forms the partial area of the bending arm, which is introduced into the undercut of the connection socket in the connection state. A plug-in surface is also arranged on the latching element, which, similar to the insertion surface on the connecting socket, facilitates bringing the connecting plug and connecting socket together and inserting them into one another. The plug-in surface extends in the radial direction to the plug-in axle and is inclined relative to it. In order to enable a symmetrical, non-positive connection between the connecting plug and a connecting socket, a plurality of bending arms are preferably arranged at regular intervals around the plug-in axle. In a connection state, in which the connector plug is connected to the connector socket, the bending area is at least partially introduced into the receptacle. The projection of the locking element is in the connection state in the undercut. A fixing surface, which is arranged on the side of the projection facing the base, rests against the holding surface in the undercut of the connecting socket. Because the fixing surface rests on the holding surface, there is also a form fit in the connection state between the connector plug and the connector socket.

A connector according to the invention is suitable for reversibly connecting two components, for example two panels, to one another. The connector can be attached to the components in a simple manner and connected and disconnected again by applying a force parallel to the connection axis or parallel to the plug-in axis. The connector can be connected and disconnected without tools. As a result, such a connection is particularly easy to handle. The connection socket can besides its property as part of the connector additionally provide the function of fixing a component, for example a panel, on a carrier or a framework. The connector according to the invention thus simplifies the replacement of a functional surface on a panel which is fastened to an underlying frame construction.

In one embodiment of the connector, it is provided that the latching element has the fixing surface on its side facing away from the plug-in axis of the plug-in surface, which is at least partially planar or conical. In this embodiment, the fixing surface is arranged on the latching element and can also extend outside of the projection. The fixing surface is arranged on a side opposite to the plug-in surface on the latching element. The fixing surface points to the base.

In a further embodiment it is provided that the base is detachably connected to an adapter, with the base being positively fitted at least in some areas into a recess which is arranged in the adapter and the connection between the base and the adapter being made by moving the base relative to the Adapter can be produced and detached in a direction perpendicular to the through-axle. In this embodiment, the connector additionally comprises an adapter, which is a connecting link between a component, for example a board, and the connector plug. When attaching the connector plug to a component, the adapter is first attached to or in the component. The connector plug is then connected to the adapter in a form-fitting manner. The provision of this adapter facilitates replacement of the connector plug in a case where wear or damage occurs there. A recess with at least one undercut is arranged in the adapter, into which the base of the connector plug is inserted at least in certain areas. This insertion of the connecting plug into the adapter takes place in a direction that is oriented perpendicularly to the plug-in axis. Replacing the connector plug in the adapter is therefore possible with a simple, linear movement. No tools are required for inserting and removing the connecting plug. Preferably, the entire connector is designed so that wear, which inevitably occurs when the connector is connected and disconnected many times, occurs for the most part on the connector plug. Due to the fact that the connecting plug can be exchanged in a simple manner due to the arrangement in the adapter, the entire connector can be revised quickly and easily after repeated use, in which only the connecting plug is exchanged. The connector socket is designed in such a way that there is hardly any wear and tear and is therefore designed for a higher number of connection cycles than the connector plug.

Furthermore, it is provided that the quick-release axle forms the central axis of the bending area. In this embodiment, the bending area is arranged around the through axle. This results in a symmetrical construction of the connecting plug, which is favorable for safe and stable power transmission between the connecting plug and the connecting socket.

In a further embodiment it is provided that the base extends outwards in a direction radially to the plug-in axis away from the bending arm and the base has at least one fastening area which is designed in particular as an opening, external thread or fastening pin. In this embodiment, the connector plug is not intended to be connected to a component via an adapter. Instead, the base has a fastening area which is provided for directly fastening the connector plug to a component, for example a board. This fastening area can be designed, for example, as an opening through which a fastening component, such as a screw, can be guided. Alternatively, the fastening area can also be designed as an external thread, for example, which is screwed into a corresponding internal thread on the component. The fastening area can also be designed differently, for example as a fastening pin, which can be driven into a component like a nail for the positive and non-positive connection of the connector plug.

Provision is advantageously made for the plug-in surface to be curved or rounded at least in certain areas. When the connecting plug is connected to the connecting socket, the plug-in surface preferably slides along the insertion surface. It has been found that a domed or rounded shape of one of the two surfaces is suitable to reduce the mating force required to insert the connector plug into the connector socket. For example, the plug-in surface can therefore be rounded or curved. Alternatively, the insertion surface on the connection socket can also be rounded or curved.

It is provided that in the connected state, the bending element is elastically deformed compared to a non-connected state, whereby a non-positive connection between the bending arm and the receptacle, in particular the undercut connection exists. In the connection state, the bending element is elastically deformed in such a way that the deformation in the bending element generates a restoring force which is directed in a direction radially to the connection axis and to the plug-in axis. This restoring force pushes the bending arm in the direction of the undercut and thus pushes the latching element into the undercut. As a result, both a non-positive and a positive connection are established between the connecting socket and the connecting plug.

Provision is preferably made for the plug-in axle and the connection axle to be aligned parallel to one another or coaxially in the connection state. By aligning the plug-in axle and the connection axle in parallel, the connector plug and the connector socket can be connected and disconnected again in a simple linear movement. In the connection state, the plug-in axle and the connection axle are preferably aligned coaxially with one another and thus form a common axle.

Furthermore, it is provided that, in the connected state, the connecting socket and the connecting plug are connected to one another in a positive and non-positive manner in a direction parallel to the connection axis, in particular are braced. In the connection state, the connection socket and the connection plug of the connector are connected with each other without play. This is achieved by an at least partially non-positive connection. Such a play-free connection achieves a secure, long-term stable connection between the components of the connector, even under dynamic loads.

The object of the invention is further achieved by a fixed double panel, comprising a base panel and a cover panel, which are aligned parallel to one another and rest on one another at least in regions, the base panel and the cover panel being connected to one another by at least one connector according to one of the embodiments described above, and at least one carrier, with the connecting bushing being introduced into the base plate and the connecting plug being connected to the cover plate and protruding at least in some areas beyond it, and the base plate being connected through the connecting bushing to the carrier, which is arranged on the side of the base plate facing away from the cover plate is, wherein the pressure surface rests on a surface of the base plate facing the cover plate and the fastening element connects the connection socket to the carrier, in particular connects it in a non-positive manner.

A fixed double panel according to the invention comprises the components base panel, cover panel and carrier. In this case, the carrier preferably belongs to a frame construction which is intended to carry and position at least one panel, in particular a panel with a functional surface. The double board is a combination of two boards, of which the base board preferably has a supporting, load-bearing function and the cover board provides a functional surface facing away from the carrier. For example, a double panel fixed according to the present invention can be used to provide an electrical panel in the construction field. However, the dual panel fixed according to the present invention is not limited to this use.

The base plate and the cover plate are placed on top of one another at least in regions in the case of the double plate fastened according to the invention. It is possible that the base plate and cover plate are in full contact with one another. The base plate is connected to the cover plate by at least one connector according to one of the previously described embodiments. The carrier is located on the side of the base plate opposite the top plate. The carrier preferably rests on only a partial area of the surface of the base plate. For example, the contact surface between the base plate and the carrier can be between 2 and 25% of the surface of the base plate. The connecting socket of the connector is at least partially introduced into the base plate. The connecting plug of the connector is arranged on or in the cover plate and protrudes at least in regions beyond the surface of the cover plate facing in the direction of the base plate. In the mounted state, at least part of the bending area of the connecting plug can be introduced into the receptacle of the connecting socket and the connector can thus be converted into the connected state. In the state in which the cover plate rests on the base plate, the connector is in the connection state and fixes the base plate to the cover plate in a direction parallel to the connection axis and the thru-axle.

The connection socket is additionally connected to the carrier by its fastening element. The cover plate is attached to the beam through or with the help of the connection socket. With this non-positive connection, the flow of force runs from the base plate via the pressure surface into the connecting bush and from the connecting bush via the fastening element into the carrier. The pressure surface rests over a large area on a surface of the base plate facing in the direction of the cover plate. With this fastening, the pressure surface acts in a similar way to a washer in a normal screw connection and increases the Force application area for the non-positive connection between the base plate and the carrier. With the attached double plate according to the invention, the cover plate can be separated from the base plate in a very simple manner. All that is required for this is to remove the connection state of the connector, which can be done by applying a force parallel to the connection axis or to the plug-in axis in a direction away from the carrier. The removal of the cover plate is thus possible in a very simple manner in the case of the double plate fastened according to the invention. Likewise, the assembly of the same or another cover plate on the base plate is also easy to carry out, in that the cover plate is moved towards the base plate by applying a compressive force which acts towards the carrier. If the cover plate is removed or replaced, the connection between the base plate and the carrier can remain. This has the advantage that when the cover plate wears out, it can be replaced quickly and easily, while the base plate and the carrier remain connected to one another in an unchanged manner. The two plates arranged parallel to one another can be designed in such a way that the base plate has the load-bearing properties and the cover plate is designed to be light and thin. In this case, replacing the top panel is significantly more resource-efficient than a solution where only a single panel is used to provide both the load-bearing properties and the required surface properties.

In one embodiment of the fixed double plate, it is provided that the cover plate has a functional surface facing away from the base plate and the cover plate can be separated from the base plate by releasing the connector, the connection between the cover plate and base plate being made by applying a force which acts parallel to the connection axis and from the base plate is directed away, is detachable. In this embodiment, a functional surface is applied to the surface of the cover plate pointing away from the base plate and the carrier.

In the example where the fixed double plate is used for providing a switchboard, the functional surface of the cover plate can be formed by a concrete-repellent and water-repellent coating. As previously described, the cover plate can be easily separated from the base plate by releasing the connector. If the functional surface on the cover plate wears out, it can be easily replaced. A fastened double plate thus simplifies the replacement or renewal of a functional surface on a plate which is fastened to an underlying frame construction.

In a further embodiment it is provided that the cover plate is formed by a formwork skin, the base plate by a reinforcement plate and the carrier by a formwork frame, with several spaced apart connectors detachably connecting the cover plate, base plate and carrier to one another in the connected state. In this particular embodiment, the attached double panel is designed as part of a formwork for the construction sector. The carrier is formed by a formwork frame, which is preferably a lattice structure made of steel profiles. The base plate is a reinforcement plate connected to the formwork frame, which is intended to carry the actual formwork skin and to derive forces from it. The base plate can be formed by a metal plate or by a plastic plate or an untreated wooden plate. The cover plate is formed by a formwork skin which has a concrete-repellent functional surface on its side facing away from the reinforcement plate. The cover plate as formlining is thin and has no load-bearing properties. If the functional surface wears out, the cover plate can, as described above, be replaced quickly and easily, with the rest of the structure of the formwork not having to be changed. If necessary, however, it is also possible to exchange the base plate or reinforcement plate, which is detachably connected to the carrier via the connecting bush. In this embodiment, several connectors are preferably arranged between the base plate and the cover plate, which are preferably attached in the edge region.

Disclosed is the use of a connector according to one of the above-described embodiments for connecting a base plate to a cover plate, the connecting socket being inserted into the base plate and the connecting plug being connected to the cover plate and protruding at least in regions over it and the pressure surface on one of the cover plates facing Surface of the base plate rests and the fastening element connects the connection socket to a carrier, in particular connects it in a non-positive manner. The use of a connector according to one of the previously described embodiments for connecting a cover plate to a base plate and to a carrier simplifies the replacement of a functional surface applied to the cover plate compared to the prior art. In this case, the carrier preferably belongs to a frame construction which carries the two plates.

A method for fastening at least two boards on a carrier using at least one connector according to one of the previously described embodiments is disclosed, comprising the steps

1. A) Fastening a base plate on a support, with the pressure surface of the connecting bush being placed on a surface of the base plate and the fastening element of the connecting bush being connected to the support, with the base plate being connected in a non-positive and/or positive manner through the connecting bush at the end of method step A). connected to the carrier
2. B) Fastening a cover plate on the assembly of base plate and carrier from method step A), wherein a connector plug is attached to a surface of the cover plate and the connector plug is inserted into the connection socket connected to the base plate and the connector is thus converted into the connected state.

The method is used to attach two panels to a carrier. The process is preferably carried out in the specified order of process steps A) and B). To separate the two plates from the carrier, the procedure can be carried out in reverse order.

In a first method step, a base plate is attached to a carrier. In this case, the carrier preferably belongs to a frame construction which carries the two plates. The connection socket of the connector is used to fasten the base plate to the support. Its printing surface is placed on a surface of the base plate which faces away from the carrier. The fastening element is then connected to the carrier.

This connection leads to a tensioning of the base plate on the carrier. The power flow for this bracing is guided through the connecting bush. At the end of method step A), the base plate is non-positively and preferably also positively connected to the carrier.

In a second method step B), the cover plate is fastened to the composite of base plate and carrier that has already been produced by the connector. For this purpose, a connecting plug, which is fastened to the surface of the cover plate facing the base plate, is inserted into the connecting socket introduced into the base plate and the connection state is established. This connection state can be established in a simple manner by applying a compressive force to the cover plate which runs parallel to the connection axis and to the plug-in axis in the direction of the carrier.

The method thus first attaches the base plate to the carrier and then the cover plate to the base plate. The procedure is easy to carry out. The method can also optionally be supplemented by further method steps. For example, in a further method step, the cover plate can be separated from the base plate again and replaced. However, this further optional method step is preferably carried out much later, in particular when the cover plate is worn after prolonged use and needs to be replaced or renewed.

The features, effects and advantages described in connection with the connecting socket, the connector and the attached double plate can also be transferred analogously to the use and the method and are therefore also disclosed. The same applies in the opposite direction: features, effects and advantages that are described in connection with the methods or the use can also be transferred to the connection socket, the connector and the attached double plate and are considered to be disclosed as well.

1 shows a perspective view of a first embodiment of a connection socket 1 according to the invention. In the illustration, a connection axis VA is drawn in vertically, which is an imaginary axis, in the direction of which the connection socket 1 is connected to a connection plug 2, such as, for example 3 shown, can be connected. The connection axis VA thus corresponds to a connection direction with the connection socket 1 with a connection plug 2 to a connector 100, such as in FIG 6 shown, can be connected. This connector 100 is preferably connected and disconnected in the direction of the connection axis VA. The connection axis VA also serves as an imaginary auxiliary geometry to describe the structure of the connection socket 1.

The connection socket 1 comprises a casing 11 which extends along the connection axis VA and completely encloses the connection axis VA in the illustrated embodiment. However, it is also possible for the casing 11 to only partially enclose the connection axis VA. In this embodiment, the outer surface of the jacket 11 pointing away from the connection axis VA has the shape of a circular cylinder. The outer surface of the jacket 11 can also be shaped differently and, for example, have the shape of a cuboid. The wall thickness of the jacket 11 varies along the connection axis VA, which 2 can be seen. A receptacle 111 , which is provided for accommodating a partial area of a connector plug 2 , is arranged inside the casing 11 . The receptacle 111 is delimited by the jacket 11 . The receptacle 111 in the illustrated embodiment has the shape of two connected cones, which can be seen in the sectional view in 2 can be seen in detail. The connecting socket 1 comprises a base area 12 which, in the perspective view, is shown in 1 can be seen through the receptacle 111. The bottom area 12 is connected to the casing 11 and extends at right angles to the connection axis VA. The base area 12 delimits the receptacle 111 and the entire connection socket 1 in the direction of the connection axis VA on the lower side. In the illustrated embodiment, the bottom area 12 is designed as a flat circular disk, which has its center at the point of intersection with the connecting axis VA. The base area 12 delimits the receptacle 111 here together with the jacket 11. The connection bushing 1 further comprises a fastening element 13, which in the illustrated embodiment is designed as a fastening opening which penetrates the base area 12 and is oriented coaxially to the connection axis VA. A fastening component, for example a screw, can be introduced into this fastening opening in order to fasten the connection socket. Such a fastening element designed as a fastening opening can alternatively also be arranged in the jacket 11 and penetrate through it. Furthermore, it is possible to provide several fastening elements 13 which are arranged at different points on or in the connection socket 1 . The connecting sleeve 1 also includes a pressure surface 14 which is arranged here on the underside of a collar 17 connected to the jacket 11 . The collar 17 is arranged in the end of the jacket 11 facing away from the base area 12 in the direction of the connection axis VA. The collar 17 extends from the outer surface of the shell 11 in a radial direction away from the connection axis VA. The pressure surface 14 is formed by a circumferential, conically shaped surface on the underside of the collar 17. The pressure surface 14 is intended to hold and fix a component, in particular a plate, into which the jacket 11 of the connection socket 1 is inserted. Details of this fixation are in connection with 6 described. In an alternative embodiment, the collar 17 can also be omitted and a pressure surface 14 can be arranged on the flat side of the bottom area 12 facing downwards.

The connecting socket 1 also includes an undercut 15 which forms a cavity inside the casing 11 . This undercut 15 is part of the recess 111 in the illustrated embodiment. The undercut 15 is arranged between the base area 12 and the collar 17 in an inner peripheral surface of the casing 11 . The undercut 15 is delimited in the direction of the connection axis VA on two opposite sides by elements or areas of the connection socket 1 which protrude in the radial direction in relation to the connection axis VA. The undercut 15 is designed to be open inwards in the interior of the jacket 11 in the radial direction relative to the connection axis VA. The undercut 15 is used in the connected state with a connecting plug 2 to accommodate a latching element 2212. In the connected state, the undercut 15 and the latching element 2212 then form a form fit. For example, this is in 6 to see. Furthermore, the connection socket 1 comprises an insertion surface 16 which is arranged on the casing 11 and/or on the collar 17 . This insertion surface 16 is conical in the illustrated embodiment and extends in the radial direction to the connection axis VA, the insertion surface 16 also being inclined to the connection axis VA. In the illustrated embodiment, the insertion surface 16 is arranged circumferentially around the connection axis VA. The insertion surface 16 facilitates the insertion of a connector plug 2. In alternative embodiments, the insertion surface 16 can also be arranged only in regions in the circumferential direction around the connection axis. In addition, it is possible for the insertion surface 16 to have a conical shape other than that shown. For example, it is possible to design the insertion surface to be curved in one or more directions. Furthermore, it is possible to provide several insertion surfaces 16 which are spaced apart from one another and which each have flat surfaces. In the illustrated embodiment, the entire connection socket 1 is formed in a rotationally symmetrical manner about the connection axis VA. In this way, such a connecting socket 1 can be connected to a connecting plug 2 in the same way in any rotational position. This facilitates the installation of the connecting socket 1 and the connection with a connecting plug 2. Alternatively, the connecting socket 1 can also be shaped differently and, for example, have a rectangular or square external shape in a plan view from the direction of the connection axis VA. In such an embodiment, a corresponding connecting plug 2 must then be rotated and positioned correctly in relation to the geometry of the connecting socket 1 before the connection is made. Such a non-rotationally symmetrical shape makes sense if a connection should only be possible in a certain orientation of the connection axis 1 and the connection plug 2 .

2 shows a sectional view of a first embodiment of a connecting sleeve 1 according to the invention 2 is the first embodiment of a connector 1 from 1 shown in section in a sectional plane within which the connection axis VA runs. The sectional plane thus bisects the connecting socket 1. The base region 12 has a boundary surface pointing downwards, which is oriented perpendicularly to the connecting axis VA. The bottom area 12 closes off the casing 11 on the side facing downwards. The fastening element 13 in the form of a fastening opening is arranged centrally in the bottom region 12 . On the upward-facing side of the base area 12 adjoins a flat surface adjacent to the fastening element 13 . This planar surface can be used as a force introduction surface 131 on which, for example, a screw head of a screw that is inserted into the fastening element 13 can rest. The force introduction surface 131 ensures good force transmission and thus secure attachment of the connection socket 1 to other elements. The pressure surface 14 arranged on the collar 17 can be seen clearly in the sectional view. The pressure surface 14 extends in the radial direction from the outer surface of the shell 11 away from the connection axis VA and is inclined to the connection axis VA. The diameter of the end of the collar 17 pointing upwards is greater than the outer diameter of the casing 11. In the embodiment shown, the insertion surface 16 is arranged in certain areas on the collar 17 and in certain areas on the casing 11. The insertion surface 16 is arranged adjacent to the undercut 15, with a transition area being arranged between the insertion surface 16 and the undercut 15, which is rounded.

The receptacle 111 is arranged inside the casing 11 . The receptacle 111 is delimited by the jacket 11 in the circumferential direction around the connection axis VA. The receptacle 111 is delimited by the bottom area 12 on the end face facing downwards. The receptacle 111 is open on the end face facing upwards, with the insertion surface 16 adjoining the open side of the receptacle 111 . The undercut 15 is arranged on the inside of the jacket 11 oriented toward the connection axis VA and forms part of the receptacle 111. For better visibility, a vertical, dashed line is drawn starting from the bottom area 12 to the insertion surface 16, which is an imaginary boundary of the undercut 15 represents in the direction of the connection axis VA. In the sectional view shown, the undercut 15 thus has a triangular cross section, which is oriented around the connection axis VA and thus defines an annular undercut 15 . The undercut 15 is delimited in the direction of the connection axis on two opposite sides by elements protruding in the radial direction to the connection axis VA and adjacent to the undercut 15 . Above the undercut 15 in the radial direction towards the connection axis VA there projects as an adjacent element a projection which is arranged on the radially inward-facing end of the insertion surface 16 . Below the undercut 15, the transition area between the casing 11 and the base area 12 protrudes in the radial direction inwards towards the connection axis VA over the undercut 15. The undercut 15 thus forms a cavity inside the jacket 11, which can only be reached in the radial direction to the connection axis VA. The undercut 15 has a holding surface 151 which is arranged on the side facing away from the base area 12 . The holding surface 151 forms a surface with which a connection plug 2 connected to the connection socket 1 forms a form fit. The holding surface 151 is oriented at an acute angle to a plane which is perpendicular to the connection axis VA. In the illustrated embodiment, the holding surface 151 is conically shaped and encloses the entire connection axis VA. The inclination of the holding surface 151 is opposite to the inclination of the insertion surface 16. The radial distance of the edge of the insertion surface 16 facing away from the base area 12 to the connection axis VA is greater than the radial distance of the edge of the insertion surface 16 facing the base area. The insertion surface 16 is thus starting from inclined towards its edge facing away from the bottom surface 12 towards its edge facing the bottom surface 12 in such a way that it runs towards the connecting axis VA. In the case of the holding surface 151, the situation is exactly the opposite. Starting from its edge facing away from the base area 12 to its edge facing the base area 12, the holding surface inclines away from the connecting axis VA. The insertion surface 16 and the holding surface 151 are located adjacent to each other and are oriented at an acute angle to each other. In the illustrated embodiment, both the insertion surface 16 and the holding surface 151 are conical, with both surfaces being oriented towards one another in such a way that the side with the smaller diameter of the cone is arranged adjacent to the other surface. On its side facing the bottom area 12 , the undercut 15 has a further conically shaped boundary surface, which connects the holding surface 151 to the bottom area 12 . However, the shape of this further boundary surface can also be designed differently, since it only serves to provide enough space to accommodate areas or components of a connector plug 2 inserted into the connector socket 1 . In the illustrated embodiment, the receptacle 111 with the undercut 15 has the shape of a double truncated cone, with the holding surface 151 forming an upper truncated cone and the further boundary surface of the undercut 15 forming a second lower truncated cone. Both truncated cones are oriented towards each other with their broader sides. The described combination of the shapes of insertion surface 16, undercut 15 and holding surface 151 allows a connecting plug 2 to be inserted into the connecting socket 1 with little assembly force along the connecting axis VA and, in the connected state, a large holding force is provided along the connecting axis VA. The shape of the illustrated embodiment is easy to handle, robust and inexpensive to produce as a plastic part.

3 shows a perspective view of a first embodiment of a connector plug 2. The connector plug 2 shown represents the counterpart to the connector socket 1 according to the first embodiment 1 and 2 This connector plug 2 can form a connector 100 together with the connector socket 1, which in the connected state in 6 is shown in a sectional view. The connector plug 2 has a base 21 shown in the illustration below, which supports the remaining elements of the connector plug 2 . The base 21 is designed here as a circular disk. However, the base 21 can also be shaped differently. The connector plug 2 is connected to another element, for example a plate, via the base 21 . The base 21 can be customized to be optimized for connection to another element. In the illustrated embodiment, the disc-shaped base 21 is optimized for connection to an adapter 6, which is 6 is shown. An imaginary plug-in axis SA runs perpendicular to the base 21 . The stub axle SA defines the direction in which the connector plug 2 can be connected to and disconnected from a connector socket 1 . When the connection socket 1 is brought together with the connection plug 2, the plug-in axis SA and the connection axis VA are aligned coaxially with one another. The imaginary plug-in axis SA also serves to simplify the description of the components of the connector plug 2. Above the base 21, the connector plug 2 has a bending area 22 which here includes four elastically deformable bending arms 221. These bending arms 221 deform elastically when making and breaking a connection with a connection socket 1. Inside the four bending arms 221 there is a bending inner space 23 through which the plug-in axle SA runs. The bending interior 23 is opened on its side facing away from the base 21 . When the bending arms 221 are deformed, the bending interior 23 provides space into which the deformed bending arms 221 can penetrate. It is also possible to provide more or fewer bending arms 221 than the four illustrated. Each bending arm 221 comprises a bending element 2211 connected to the base 21. This bending element 2211 is elastically deformable in a direction radial to the plug-in axle SA. With an elastic deformation in this direction, the bending element 2211 builds up a spring force which can be used to fix the connector plug 2 in a connector socket 1 . On the side of each bending element 2211 facing away from the base 21, a latching element 2212 is arranged, which is provided to create a form fit with the undercut 15 when connected to a connection socket 1. A projection 22121 is arranged on the latching element 2212, which forms the region of a bending arm 221 that protrudes furthest in the radial direction from the plug-in axle SA. The projection 22121 protrudes beyond the bending element 2211. Two functional surfaces are provided on the latching element 2212 and/or the projection 22121, which are required when connecting to a connecting socket 1. On the side of the latching element 2212, which points away from the base 21, a plug-in surface 22122 is arranged, which is shaped like a portion of a cone here. The plug-in surface 22122 extends in the radial direction to the plug-in axis SA and is inclined to the plug-in axis SA. The mating surface 22122 is brought into contact with the insertion surface 16 to establish a connection with a connection socket 1 . Through the interaction of the insertion surface 16 and the plug-in surface 22122, the bending arm 221 is so elastically deformed that it can be inserted into the receptacle 111 of the connecting axle 1. The plug-in surface 22122 can also be arched or rounded. A fixing surface 22123 is arranged as a second functional surface on the latching element 2212 adjacent to the plug-in surface 22122 . The fixing surface 22123 is arranged in the direction of the plug-in axis SA on the side of the latching element 2212 facing away from the plug-in surface 22122 . The fixing surface 22123 rests against the holding surface 151 when the connector plug 2 is in the connected state with a connector socket 1 . In the illustrated embodiment, the fixing surface 22123 is designed as a partial area of a cone, the inclination of which is complementary in shape to the holding surface 151 of the connecting socket 1 . The fixing surface 22123 protrudes outwards beyond the bending element 2211 in the radial direction toward the plug-in axle SA. In the embodiment shown, the bending area 224 comprises bending arms 221 arranged regularly around the through axle SA. The number of bending arms 221 can also differ in other embodiments, for example two, three or six bending arms 221 can be provided. The bending arms 221 are arranged at the same distance from the stub axle SA and the stub axle SA forms the central axis of the bending area 22.

4 shows a sectional view of a first embodiment of a connector plug 1. In 4 connector 2 is off 3 shown in section, with the through-axle SA lying in the sectional plane. The sectional plane runs between the bending arms 221 so that these are not shown in section. The individual sections of the connector 2 are associated with 3 described, this description also applies to 4 . In the sectional view in 4 two of the bending arms 221 can be seen. These bending arms 221 are arranged symmetrically to the plug-in axle SA. The bending element 2211 of each bending arm 221 has a constant thickness in the direction of the plug-in axis SA between the base 21 and the locking element 2212 . In 4 the connector plug 2 is shown in an orientation in which it can be inserted into the 2 shown connector 1 can be introduced and connected to it. At the beginning of a connection between the connector plug 2 and the connector socket 1, the plug-in axis SA and the connection axis VA are first oriented coaxially to one another. The plug-in surface 22122 is then brought into contact with the insertion surface 16 . A force is then exerted parallel to the plug-in axis SA and to the connection axis VA, which force compresses the connector plug 2 and the connection axis 1 . By applying this force, the bending arms 221 are bent inwards into the inner bending space 23 by the interaction of the plug-in surface 22122 and the insertion surface 16 . In this state, the bending portion 22 fits through the opening inside the insertion surface 16 and the latching elements 2212 can penetrate into the receptacle 111 and the undercut 15. There, the bending arms 221 spring back elastically into their original shape, as a result of which the fixing surfaces 22123 come into contact with the holding surface 151. In this connection state, the connector plug 2 and the connection axis 1 are fixed to one another in a non-positive and positive manner. This connection state is in 6 shown.

5 shows a fixed double plate 1000 in an overview from several perspectives. The representations in 5 show an application in which a connector 100 can be used. A double plate 1000 can be seen, which comprises a base plate 3 and a cover plate 4, which are connected to one another. The base plate 3 is attached to a carrier 5 together with the cover plate 4 . The double plate 1000 is in 5 shown in simplified form. In the plan view at the top left, the double plate 1000 can be seen from below. In the foreground is the base plate 3, which carries the cover plate 4, which is arranged in the background and is therefore not shown. A carrier 5 is shown as an example in the upper left corner. The double plate 1000 is connected to this support 5 . The carrier 5 is designed as a plate, which consists of a solid material, such as structural steel. In order to hold the double plate 1000 securely, several carriers 5 according to the embodiment shown are preferably used for attachment, which can be arranged at different positions below the cover plate 3 . The carrier 5 can also be made larger and, for example, can extend along the entire length of an edge of the double panel 1000 . The carrier 5 belongs to a framework which supports and positions one or more double panels 1000 . Bottom left in 5 A side view of the attached dual panel 1000 can be seen. In this side view, the cover plate 4 can be seen at the top. The cover plate 4 rests flat on the base plate 3 . Below the two plates, the carrier 5 can be seen on the left. A fastening component B projects downwards over the carrier 5 and is guided through a fastening element 13 designed as a fastening opening and holds a connecting socket 1 . Details of this connection are in the sectional view in 6 to recognize. In the illustrated embodiment, the base plate 3 and the cover plate 4 have substantially the same size in a plan view as shown in the top left. Top right in 5 the detail marked with a circle in the plan view at the top left, which includes the carrier 5, is shown enlarged. In this representation at the top right, the two arrows indicate the sectional plane for the view in 6 1000 with a connector 100 is defined.

6 shows a sectional view of a first embodiment of a connector 100 according to the invention. The illustration shows a section through the attached double plate 1000 in a sectional plane that is shown in 5 is drawn in the top right. The connector 100 can also be seen in this view, which connects the cover plate 4 and the base plate 3 and at the same time fixes the base plate 3 to the carrier 5 . The connector 100 comprises a connection socket 1 according to FIG 1 and 2 illustrated embodiment and a connector 1 according to in 3 and 4 illustrated embodiment. The connection socket 1 is introduced into a cylindrical opening in the base plate 3 . The diameter of this cylindrical opening corresponds to the outer diameter of the shell 11 or is slightly larger. The outer diameter of the collar 17 is larger than the inner diameter of the opening in the base plate 3. As a result, the collar 17 rests on the edge of the cylindrical opening in the base plate 3 on the side facing to the left in the illustration. In this way, there is a form fit between the connecting socket 1 and the base plate 3 in the direction of the connecting axis VA. Due to the protruding collar 17, the connecting sleeve 1 cannot be moved any further to the right through the cylindrical opening in the base plate 3. The fastening element 13 of the connection socket 1 is designed as a fastening opening through which the fastening component B is guided. The fastening member B is formed by a pan head screw. The flat head of the fastening component B lies flat on the planar force introduction surface 131 . The fastening component B has an external thread which is screwed into an internal thread in the carrier 5 . The fastening component B pulls the connecting sleeve 1 to the right parallel to the connecting axis when it is screwed into the internal thread. Due to the form fit between the collar 17 and the left-facing surface of the base plate 3, the fastening component B clamps the connection socket 1 together with the base plate 3 on the carrier 5. Due to the large contact surface between the pressure surface 14 arranged on the right of the collar 17 and the surface of the base plate 3 facing away from the carrier 5, the base plate 3 is clamped onto the carrier 5 in a stable and symmetrical manner. During this bracing or fastening, the pressure surface 14 acts like a washer, so that the surface pressure between the connecting sleeve 1 and the base plate 3 is kept low. As a result, neither the connecting sleeve 1 nor the base plate is damaged with this connection and at the same time a permanent, stable connection is ensured. In order to achieve a statically determined bracing, there is a distance between the underside of the base area 12 of the connecting sleeve 1 facing to the right and the carrier 5 , so that the base area 12 does not rest on the carrier 5 . In alternative embodiments, however, the pressure surface 14 can also be arranged on the base area 12 . Such an embodiment is, for example, in 10 to see. The connecting sleeve 1 fulfills the function of a fastening element with which the base plate 3 is clamped onto the carrier 5. This connection can be easily released by removing the connection component B, so that the base plate 3 can be replaced if necessary. The connection socket 1 fulfills a further function, namely it forms one half of a detachable connector 100 with which the cover plate 4 is fastened to the base plate 3 . 6 Fig. 12 shows the connection state of the connector 100, in which a connector plug 2 is inserted into the connector socket 1 and firmly but detachably connected thereto. The connector 2 is with the Cover plate 4 connected via the adapter 6. In this case, the connecting plug 2 protrudes in some areas beyond the surface of the cover plate 4 facing to the right in the illustration. In the embodiment shown, the bending area 22 of the connector plug 2 projects beyond the cover plate 4 . The adapter 6 connects the cover plate 4 to the connector plug 2 in a form-fitting manner. For this purpose, the base 21 is pushed into a recess with two undercuts in the adapter 6 . The adapter 6 enables the connector plug 2 to be easily replaced. Such a replacement may be necessary, for example, if the connector plug 2 is damaged or worn. The connector plug 2 can be inserted into the adapter 6 from the edge of the cover plate 4, for example. The adapter 6 can be designed and arranged in such a way that the recess with the two undercuts is accessible from the edge of the cover plate 4 . Due to the form fit between the base 21 and the undercut in the recess in the adapter 6, there is a form fit between the two components in the direction of the plug-in axle SA. The adapter 6 in turn is placed in a recess in the cover plate 4 in a form-fitting manner. In the sectional view shown, the recess in the cover plate 4 has the shape of a dovetail, into which the adapter 6 can be pushed from the edge of the cover plate 4 with a press fit. Such a recess in the cover plate 4 can be introduced in a simple manner, for example, by milling. It is of course also possible to connect the connecting plug 2 to the cover plate 4 in a different way, for example by means of screws or also by means of adhesive. In the connection state shown, the bending area 22 of the connector plug 2 is partially introduced into the recess 111 of the connector socket 1 . The latching elements 2212 are introduced into the undercut 15, as a result of which there is a form fit in the direction of the plug-in axis SA and the connection axis VA. The fixing surfaces 22123 lie flat against the holding surfaces 151 . The latching elements 2212 are pressed radially outwards away from the connection axis VA by an elastic restoring force which is generated in the bending elements 2211 . Due to this elastic restoring force, there is also a non-positive connection between the fixing surfaces 22123 and the holding surface 151. In this way, the connecting socket 1 and the connecting plug 2 are always connected to one another without play. This ensures that the cover plate 4 is securely fixed on the base plate 3 . Each fixing surface 22123 is aligned parallel to a holding surface 151 in the connection state. Both surfaces are inclined towards the connecting axis VA and the through-axle SA. Here, inclined means that these surfaces are oriented at an angle of between 1° and 89° to the connecting axis VA and to the through-axle SA. If a force is applied to the cover plate 4 parallel to the stub axle SA, which is directed away from the base plate 3, this force is converted into a force acting radially inward in the direction of the stub axle SA by the two inclined surfaces that rest on one another, fixing surface 22123 and holding surface 151 Force on each bending arm 221 translated. As a result, the bending arms 221 are bent inwards in the direction of the plug-in axle SA, with the result that the latching elements 2212 are no longer located in the undercut 15 and the positive connection between the connector plug 2 and the connection axle 1 is eliminated. In this state, the connecting plug 2 can then be pulled out of the connecting socket 1. This separation is reversible, which means that none of the elements involved is damaged. The connection can thus be established and disconnected several times. To connect the connector plug 2 and the connection axis 1, the plug-in surfaces 22122 of the bending arms 221 are placed on the insertion surface 16 and then a force is applied parallel to the plug-in axis SA, which acts from the cover plate 4 in the direction of the base plate 3. Since these surfaces are also designed to be inclined, the bending arms 221 are bent inwards, as a result of which the latching elements 2212 finally penetrate the undercut 15 again. The connection between the cover plate 4 and the base plate 3 can thus be established and separated again in a simple manner by applying forces which are oriented perpendicularly to the cover plate 4 . No tools are required for this, which makes disconnecting and connecting very easy. If wear occurs after it has been disconnected and connected several times, the connecting plug 2 can be easily replaced, as described above. The connection socket 1 can also be exchanged in a simple manner due to the reversible connection via the fastening component B. The cover plate 4 preferably has a functional surface on its side facing away from the base plate 3 . This functional surface can be formed, for example, by a coating that has water-repellent properties. Such a functional surface is required, for example, for the formwork skin of a formwork panel. The advantage of the attached double plate 1000 is that the cover plate 4 can be easily replaced independently of the base plate 3 with a functional surface. If the functional surface wears out, the cover plate 4 can be removed from the cover plate 3 by separating the connector 100, for which purpose only a force acting perpendicularly to the surface of the cover plate 4 has to be applied. The cover plate 3 remains firmly connected to the carrier 5 by the connection socket 1 . In this way, the supporting structure consisting of the carrier 5 and the base plate 3 remains unchanged and is not affected by replacing the cover plate 4. This enables a quick and at the same time secure exchange of a functional interface. The cover plate 4 can be made relatively thin and does not have to have any load-bearing properties for absorbing forces and moments. Replacing the functional surface by replacing the cover plate 4 thus results in significantly lower costs and significantly less waste than when arranging a functional surface on a single, supporting plate that is connected to a carrier 5 . When a double plate 1000 is fastened, a plurality of connectors 100 spaced apart from one another are preferably used to connect the cover plate 4 , base plate 3 and carrier 5 .

7 shows a sectional view of a second embodiment of a connecting socket 1 according to the invention. The second embodiment shown is similar to the first embodiment 1 and 2 . Unless otherwise stated, the individual areas and components of the connecting sleeve are 1 in 7 towards the description 1 and 2 referred. In the 7 The second embodiment shown differs from the first embodiment in the shape of the insertion surface 16. This insertion surface 16 of the second embodiment is curved, whereas the insertion surface 16 of the first embodiment is conical. In the sectional view in 7 the insertion surface 16 therefore has a curved cross section, which is composed of areas with different radius of curvature. However, these areas with different radii of curvature continuously merge into one another. This form of the insertion surface is particularly favorable in order to keep the force required to insert a connector plug 2 into the connector socket 1 low. It has been found that the connection force required for this connection can be effectively reduced by either the insertion surface 16 or its counterpart on the connecting plug, namely the plug-in surface 22121, being of curved design. The second embodiment of the connecting socket 1 is thus suitable for a connection with a connecting plug with a conical and therefore non-curved plug-in surface 22121, such as according to the embodiment in 3 and 4 . Alternatively, the insertion surface 16 may not be curved, for example conical, as in 1 and 2 shown, be executed and instead the plug-in surface 22121 be curved or arched in shape. The shape of the holding surface 151 of the embodiments 7 is as in the embodiments 1 and 2 designed conically. Such an embodiment is particularly favorable in order to enable a high holding force in the connection state between the connecting socket 1 and the connecting plug 2 .

8th shows a perspective view of a third embodiment of a connecting bush 2 according to the invention. The illustrated third embodiment of a connecting bush 1 differs from the first and second embodiment in particular by the arrangement of the pressure surface 14 on the base area 12 and the arrangement of the undercut 15 inside the receptacle 111 Shell 11 in the illustrated embodiment has a cylindrical outer surface. The third embodiment has a connecting projection 18 which is arranged in the receptacle 111 and is surrounded by the casing 11 . The connecting projection 18 extends, starting from the base area 12, in the direction of the connecting axis VA. The insertion surface 16 , which is designed conically, is arranged on the connecting projection 18 on its side pointing away from the bottom region 12 . In this embodiment, the fastening element 13 is designed as a fastening opening which runs coaxially to the connection axis VA and penetrates the connection projection 18 . A conically shaped force application surface 131 is arranged adjacent to the fastening opening on the side of the connecting projection 18 pointing away from the base region 12 . The undercut 15 of this embodiment is located between the bottom area 12 and the insertion surface 16 and extends in the circumferential direction around the connecting projection 18 . The connecting projection 18 is designed to be rotationally symmetrical about the connecting axis VA and is arranged coaxially thereto. The receptacle 111 is arranged between the connection projection 18 and the jacket 11 and is ring-shaped in a plan view from the direction of the connection axis VA. The undercut 15 is open to the receptacle 11 . This side, which is open in the radial direction to the connection axis VA, is arranged in this embodiment on the side of the undercut 15 pointing away from the connection axis VA.

In the third embodiment shown, some functional areas of the connecting socket 1, which in the first two embodiments are arranged adjacent to or adjacent to the casing 11, are arranged on a connecting projection 18 arranged centrally in the recess 111. A suitable connecting plug 2 for the third embodiment of the connecting socket 1 is in 9 shown.

9 shows a perspective view of a second embodiment of a connector plug 2. The illustrated second embodiment of a connector plug 2 is for connection with a connection socket 1 after the in 8th illustrated third embodiment provided. A connector 100 having a connector plug 2 according to the second embodiment is a sectional view in FIG 10 shown in connection status. The connector plug 2 according to the second embodiment is similar to the connector plug 2 according to the first embodiment in FIG 3 and 4 . Unless otherwise stated, the description applies to the individual components or elements of the connector plug 2 3 and 4 also for 9 . In the connection plug 2 according to the second embodiment, four bending arms 221 are also arranged around the plug-in axis SA. In contrast to the first embodiment, however, in the second embodiment, these bending arms 221 are bent radially outwards, away from the plug-in axle SA, when connected to a connecting socket 1 . In the second embodiment, the projection 22121 of the latching element 2212 of each bending arm 221 points inwards, in the direction of the plug-in axle SA. The plug-in surface 22122 is also arranged on the side of the latching element 2212 pointing towards the plug-in axis SA. The basic structure and the function, in particular of the partial areas of the bending arms 221, is identical to the first embodiment.

10 Fig. 12 shows a sectional view of a second embodiment of a connector 100 according to the invention. This view also shows a second embodiment of a fixed double plate 1000. The second embodiment of a connector comprises a connection socket 1 according to the third embodiment of Fig 8th and a connector plug 2 according to the second embodiment 9 . The connection socket 1 is introduced into a cylindrical recess in the base plate 3, this cylindrical recess being designed as a blind hole. In this embodiment, the pressure surface 14 is located on the side of the bottom area 12 that faces upwards in the illustration.

The pressure surface 14 lies on the bottom of the blind hole in the base plate 3 over a large area. A fastening component B is guided through the fastening element 13 designed as a fastening opening and is connected to the carrier 5 . The fastening component B is also designed here as a screw, which is screwed into an internal thread in the carrier 5 . The connecting bushing 1 is pulled towards the carrier 5 by the fastening component B and clamps the base plate 3 arranged in between to the carrier 5. Due to the large contact surface between the pressure surface 14 and the base plate, a stable connection is also ensured in this embodiment, in which the Surface pressure between connecting sleeve 1 and base plate 3 is low. On the side of the cover plate 4, the connector 2, as in the 6 shown embodiment, via an adapter 6 with the cover plate 4 connected. The representation in 10 shows the connection state in which the projections 22121 of the locking elements 2212 are introduced into the undercut 15 and these elements form a form fit there, which fixes the connecting plug 2 to the connecting socket 1 in a direction parallel to the plug-in axis SA and the connection axis VA. As in the embodiment in 6 are also in the embodiment in FIG 10 the fixing surfaces 22123 resting on one another and the holding surface 151 are oriented inclined to the connection axis VA and to the plug-in axis SA. This inclination of the surfaces, as in the embodiments 6 , When a tensile force is applied to the cover plate 4 in a direction away from the base plate 3, the bending arms 221 are deformed radially to the connection axis VA and finally the positive connection between the connecting socket 1 and the connecting plug 2 is eliminated. To produce the connection state shown, the plug-in surfaces 22122 and the insertion surface 16 arranged on the connection projection 18 are also brought into contact with one another in this embodiment and then a compressive force is exerted on the cover plate 4 in the direction of the base plate 3 . In this way, the connector 100 can be changed from the disconnected state to the connected state shown. Thus, even with the in 10 illustrated embodiment separate the cover plate 4 and the base plate 3 by the application of forces perpendicular to the surface of the cover plate 4 and connect them to each other. As with the one 6 In the illustrated embodiment, the connecting socket 1 fulfills the function of a connecting element within the framework of the connector 100 and, on the other hand, the function of a connecting element with which the cover plate 3 is connected to the carrier 5 securely and resiliently, but nevertheless detachably. Incidentally, for the properties and advantages of the in 10 shown components to the description 6 referred.

11 shows a perspective view of a fourth embodiment of a connection socket 1 according to the invention 11 illustrated embodiment is partially identical or at least similar to the first embodiment 1 and 2 built up. In contrast to the first embodiment, the fourth embodiment has no collar 17 . The pressure surface 14 is instead embodied as a surface of the shell 11 which is arranged adjacent to the outer shell surface. The pressure surface 14 is oriented perpendicularly to the connection axis VA and is arranged on a shoulder which is provided on the outer lateral surface of the jacket 11 . The Pressure surface 14 is formed by a flat, annular surface which extends circumferentially around the connection axis VA. In this case, the pressure surface 14 is set back in relation to the end face of the bottom region 12 which points downwards in the illustration. If a connecting sleeve 1 according to the fourth embodiment is to be introduced into a base plate 3 , a recess is made in the base plate 3 which is cylindrical and has a diameter which is the same as or slightly larger than the outer diameter of the cylindrical jacket 11 . However, the recess in the base plate 3 has a shoulder on its side facing the carrier 5 which is designed to complement the pressure surface 14 in shape. When a connection is made, the pressure surface 14 of the connecting sleeve 1 then rests on the shoulder in the recess in the base plate 3 . In the illustrated embodiment, the undercut 15 is arranged in the jacket 11, but differs in shape from the embodiment in FIG 1 and 2 . This difference is in 12 to recognize.

12 shows a sectional view of a fourth embodiment of a connection socket 1 according to the invention. The fourth embodiment of a connection socket 1 is shown in the sectional view 11 to see where the connection axis VA lies in the cutting plane. In the sectional view it can be seen that the undercut 15 is delimited by a curved inner wall of the jacket 11 . Thus, the holding surface 151 is also curved in this embodiment. A connecting plug 2, which is provided for connection to the embodiment shown, has a locking element 2212 designed to complement the shape of the undercut 15. In this embodiment, the insertion surface 16 has a conical shape. A cylindrically shaped area is arranged between the insertion surface 16 under the undercut 15 and has a constant diameter. The sectional view clearly shows that the pressure surface 14 runs around the connection axis VA in the circumferential direction and is arranged on a shoulder in the jacket 11 . The fastening element 13 is designed as a fastening opening. In this embodiment, the fastening element 13 with the adjacent force introduction surface 131 protrudes in the direction of the connection axis VA over the adjacently arranged floor area 12 .

13 shows three sectional views through a carrier 5 with a built-in connection socket 1. The carrier 5 is formed as a result of a steel profile which is hollow on the inside. Such a carrier can be, for example, a formwork frame of a formwork panel for the production of building parts. In 13 three different alternatives can be seen as to how a connection socket 1 can be connected to the carrier 5. In the illustration, the connection socket 1 is built directly into the carrier 5 in each case. Alternatively, a base plate 3 can also be placed between the connection socket 1 and the carrier 5, analogously to the embodiments in 6 and 11 to be built in. In each of the three views 13a to 13c, the carrier extends perpendicularly to the plane of the drawing. The connection axis VA of the connection sleeve lies in the cutting plane.

In 13a a fifth embodiment of a connection socket 1 can be seen. In this fifth embodiment, the fastening element 13 of the connection socket 1 is designed as an external thread, which is arranged on the outer surface of the jacket 11 facing away from the connection axis VA. This external thread is screwed into an internal thread which is cut in the surface of the carrier 5 which faces upwards. In this embodiment, no further fastening component B is required. Inside the connecting socket 1, for example in the receptacle 111, wrench flats can be provided which can be brought into contact with a tool in order to be able to screw the connecting socket 1 into the carrier 5 with increased torque.

13b shows a sixth embodiment of a connecting bush 1. In this sixth embodiment, the connecting element 13 of the connecting bush 1 is formed by welding or gluing between the collar 17 and the surface of the carrier 5 arranged adjacent thereto. This possibility of attachment is particularly easy to produce. In a case where the connecting sleeve 1 is made of plastic, it can be easily glued to an opening in the support 5. In a case where the connecting sleeve 1 and the support 5 are made of metallic materials, a welded connection can also be made between the two components.

13C shows a seventh embodiment of a connector socket. In this embodiment, the connecting socket 1 is connected to the carrier 5 by riveting. For this purpose, the connection socket 1 was first introduced into the carrier 5 through a cylindrical opening in the side facing upwards. Subsequently, the connecting socket 1 was upset inside the carrier 5, so that the previously cylindrically shaped outer surface of the jacket 1 has a permanent outward curvature. The casing 11 was thus plastically deformed and compressed during riveting in a direction parallel to the connection axis VA. Through this deformation became a form Connection made between the connecting sleeve 1 and a wall of the carrier 5, which fixes the connecting sleeve 1 relative to the carrier 5. Appropriate tools can be brought into contact with the bottom area 12 and the collar 17 to produce the upsetting or riveting. For this embodiment, it is advisable to produce the connection socket 1 from a plastically deformable material, for example a metal.
