Description

State of the art

Plug-in devices with a socket on a support structure such as a wall or a profile element and a plug-in part that matches the socket and that can be detachably connected to one another are used in various configurations. For example, plug-in devices are used to accommodate arrangements for the presentation of objects such as goods in sales or exhibition rooms, preferably on the walls of the sales rooms.

The highest demands on functionality, technology, optics and assembly situation are placed on the plug-in device.

Object and advantages of the invention

The object of the present invention is to provide an insertion device of the type described in the introduction in an improved manner for an arrangement for the presentation of goods or, specifically, a goods presentation insertion device, in particular with regard to providing an expanded functionality of the insertion device. The extended functionality of the plug-in device does not affect the wearing property of the plug-in device. The expanded functionality is used to provide increased convenience of the plug-in device, for example for an optically or visually improved presentation of goods.

This problem is solved by the independent claims.

The dependent claims address advantageous and expedient variants of the invention.

The present invention is based on an insertion device for an arrangement for the presentation of goods with a socket that can be attached to a support structure and an insertion part separate from the socket, the insertion part having an insertion section which is inserted into a receptacle of the socket in an insertion direction along an insertion axis until it is reached a connection state of the plug-in device can be inserted, so that in the connection state the plug-in part and the socket are detachably connected to one another,
wherein the plug-in section has a front area and an outer jacket area, and wherein the receptacle of the socket has a front section facing in the insertion direction and an inside jacket area, the jacket area of the plug-in section and the jacket area of the receptacle coming into contact with one another in the connected state. In addition, an electrification arrangement is provided in order to electrically supply an electrical load via the plug-in device in the connected state of the plug-in device, an electrical connection via the socket and the plug-in part being set up for the electrical supply by creating an electrically conductive contact through galvanic contact between a first contact point a contact section of the electrification arrangement is set up on the socket and a second contact point of a contact section of the electrification arrangement is set up on the plug-in section.

In the present case, a contact point is understood to mean, in particular, a physical area that exists regardless of whether a galvanic contact is currently or is currently set up or not. For this reason, non-contacted areas, which are e.g. temporarily galvanically separated, are referred to as contact points.

The socket in particular has a section for attaching the socket to the support structure. This can for example Through holes in z. B. be a flange portion of the socket for this penetrating screw means for screwing the socket on a rear wall of a wall element or a profile rail. The receptacle provides a cavity that is open for insertion, the receptacle being accessible or open from an insertion side for the attachment of the insertion part in the mounting situation attached to the support structure. For example, when the socket is regularly attached to the rear wall, the receptacle is freely accessible from the front or visible wall side via a prepared hole in a corresponding wall element, which is for example aligned with an opening in the receptacle at the front, with the remaining sections of the socket from the wall element are covered.

The receptacle preferably has the jacket region or a wall section that delimits the receptacle radially in relation to the insertion direction, with an axial length corresponding to the length of the insertion section. The jacket area is preferably designed to taper in the insertion direction, which relates to the inside of a socket wall of the socket. The socket wall can protrude outside the rear on the flat flange portion of the socket z. B. outside sleeve-shaped z. B. be cylindrical.

The plug-in section preferably comprises an outer jacket area that is matched to the jacket area of the socket, the jacket area of the receptacle and the jacket area of the plug-in section, or at least essential areas thereof, coming into flat contact with one another in the connected state of the plug-in device, so that a solid contact over the flat contact Holding state of the male part is set up on the socket. In this way, comparatively large holding forces can advantageously be implemented in a compact manner when the plug-in part and socket are connected.

The jacket area of the receptacle on the inside of the socket is designed to taper in the insertion direction, preferably conically tapered. Corresponding to the conicity of the socket jacket area, the outer jacket area of the plug-in part is also designed to taper conically.

The jacket area of the receptacle is preferably designed at least essentially as a straight truncated cone, as is the jacket area of the insertion section.

An anti-twist device acting between the socket and the plug-in part is also preferably configured to prevent a rotary movement of the plug-in part about the plug-in axis of the plug-in part in the connected state of the plug-in device.

The essence of the present invention is that the first contact point is formed on the socket in the jacket area of the receptacle and that on the plug-in section the second contact point is formed in the jacket area of the plug-in section, so that in the connected state the first contact point in the jacket area of the socket and the second contact point are in electrical contact with one another in the jacket region of the insertion section.

An electrical contact means that galvanic contact is established between the two contact points.

This means that any electrical consumer on the plug-in part can advantageously be supplied electrically via the plug-in device, such as an electrical lighting device or lighting arrangement for lighting and illuminating a goods presentation area in which goods are or can be presented. This increases the functionality of the plug-in device with regard to the optically advantageous presentation of goods.

In the connected state, provided it takes place e.g. B. from the outside via a power grid an electrical supply of the Instead of the contact section of the socket, the contact section of the plug-in part can be electrified. From there z. B. an electrical connection line to the consumer. Switching means for switching or, for example, for manually switching on and switching off the electrical supply of the electrical consumer are preferably provided on the plug-in device or the goods display arrangement and / or outside.

The first contact point and the second contact point are preferably adjacent to one another in the radial direction with respect to the insertion axis. The first contact point and the second contact point have, for example, a distance of z. B. 2, 5, 10 millimeters to the respective end area of the socket base and a free end of the insertion section.

The contact section of the electrification arrangement on the socket advantageously has two spaced apart first contact points and the contact section of the electrification arrangement on the plug-in section has two spaced apart second contact points, a first contact point and a second contact point which are connected to one another to form a common electrical pole are associated. The contact section on the socket is preferably formed by two separate components, as is the contact section on the plug-in section, for example the respective contact section is formed by two strip-shaped metallic plates.

In the connected state, both first contact points are preferably in galvanic contact with the associated second contact point, so that a two-pole electrical supply can be set up. Preferably, in relation to a central longitudinal axis of the plug-in device or to the plug-in axis, the contact points are opposite or radially opposite, preferably at the same axial height or in a common axial plane.

It is also advantageous that there is an outwardly open opening in the jacket region of the receptacle, the galvanic contacting of the first contact point with the second contact point being established via the opening when the plug-in device is connected. The opening is present in the jacket area of the receptacle or an associated wall section which surrounds the receptacle.

The receptacle with its receptacle volume for the plug-in section is preferably pot-like or open to the front according to a front axial opening for plugging in the plug-in section. At the rear or axially opposite the front axial opening, the receptacle is preferably closed by a socket or pot base. The opening comprises only a comparatively small opening area. The opening is preferably over an axial partial length of the wall section and over a partial circumference of, for. B. 10 to 30 degrees. For the different electrical poles or differently polarized contacts, there are preferably two radially opposite openings in the jacket area or in the associated wall section.

An advantageous variant consists in that the socket has a socket base which is axially aligned with the insertion axis, the socket base being at least substantially closed. This makes the socket easy to manufacture. In addition, the receptacle of the socket into which the plug-in section can be inserted is protected against the penetration of dirt or moisture into the receptacle from a rear side of the socket in the attached state or from areas behind the supporting structure such as the supporting wall.

The socket base closes the sleeve-shaped wall section at the rear or at the rear or against the insertion side. In the area of the socket base, there is no galvanic contact or no electrically conductive feed or connection, or no electrical line contact is made available for the electrical supply. Preferably the socket base is completely or at least substantially closed. With the socket base, the receptacle of the socket is designed to be closed in its end facing in the direction of insertion. A permanent magnet, for example, can advantageously be accommodated in the area of the socket base for holding the plug-in section that is magnetic for this purpose on the socket side.

According to another advantageous embodiment, the opening in the jacket region of the receptacle is spaced apart from the socket base in the direction of the insertion axis. Protected contact is thus possible. The opening, for example rectangular in the cylindrical wall section, is spaced from the socket base, for example over a closed area of the wall section.

Another advantage is that the plug-in section has a recess on its outside which is recessed towards sections of the outside of the plug-in section that adjoin the recess, the contact section being present on the plug-in section within the recess. The contact section has the second contact point. The contact section of the plug-in section is preferably provided on a plug-in part plug-in element. The contact section of the plug-in section and the plug-in part plug-in element are preferably designed with one another or together, for example as a plug-in element which is received in the recess, e.g. B. easily fixed by friction effects on walls of the recess and / or held by magnetic forces from magnetic means of the plug-in device. Preferably, the recess and the contact section are coordinated with the plug-in part plug-in element so that the contact section and the plug-in part plug-in element are not protruding from an envelope surface of the plug-in section or on the z. B. protrude conical outer surface of the insertion section.

The embedded or recessed placement of the Contact section, enables a compact and protected design of the electrification arrangement or the second contact point. The recess is, for example, as narrow in the longitudinal direction of the insertion section, in a width dimension of the recess over a small partial circumference of z. B. 30 to 50 or 40 degrees formed, elongated groove configured. The length of the recess is, for example, approximately half the length of the insertion section. The recess is z. B. open in the insertion direction or backwards in the direction of a free end of the insertion section. To the front, the recess extends preferably to an opening in the insertion section such as. B. a cross hole. The opening is preferably open to or connected to a cavity such. B. a longitudinal bore in a mounting portion of the male part.

The opening in the plug-in section extends close to the beginning of the plug-in section or as far as the area where the plug-in section reaches a mounting section of the plug-in part. An extension, which is part of the arrangement for displaying goods, can be attached to the attachment section.

According to an advantageous modification of the invention, the plug-in part has a cavity which is designed to receive an electrical line. The cavity is z. B. formed by a central longitudinal bore, which serves to receive an electrical conductor for routing lines from the contact section on the plug-in section to a front free end of the plug-in part. The conductor thus extends in the cavity, housed in a protected manner on the inside on the plug-in part, from the contact section on the plug-in section to an open end of the plug-in section. From there, an electrical connection to an electrical consumer of the goods display arrangement can be set up, e.g. B. via a cable extension.

Through the hole z. B. a multi-core cable electrically insulated to the outside.

The cavity serves for the protected, space-saving accommodation of an electrically conductive bridging over a substantial length of the plug-in part, in particular over a partial length of the plug-in section and preferably over the entire length of the attachment section.

The cavity preferably has a central recess or bore which is axially open at the front end of the attachment section, that is to say the end which faces away from the insertion section.

The cavity is open at its other or inner end to the opening to which the recess in the insertion section extends. This provides a continuous internal connection space between the contact section on the plug-in section and a free end of the attachment section on the plug-in part, that is to say on the side of the goods display arrangement.

The opening preferably goes completely through the insertion section and is oriented, for example, transversely to the longitudinal bore. The opening extends to the outside of one another spaced or separate opening outlets on the outside of the insertion section. Since the opening is connected to the cavity, the opening outlets are e.g. B. on the outside at radially opposite points or form open points on both sides of the outer side of the insertion section. Except for the two opening outlets on the insertion section and the axially open side of the attachment section, the cavity is preferably closed.

The contact section of the electrification arrangement is advantageously connected to the plug-in section with the electrical line that is received in the cavity of the plug-in part. This enables electrical feed-through over part of the length of the plug-in part. The Galvanic contact between the contact portion and the electrical line is preferably by z. B. a soldered connection or set up by a detachable plug contact.

The contact section of the electrification arrangement can advantageously be plugged onto a plug-in element. The contact section on the socket and the contact section on the plug-in section are preferably detachably inserted on a respective associated plug-in element.

Another advantageous embodiment provides that the contact section of the electrification arrangement is present on the socket on a socket plug element, the socket plug element being made of an electrically insulating material. Electrical insulation of the socket contact section from the socket can thus be established. The socket contact section is formed, for example, from a thin metal plate which can be inserted into a seat on the socket plug element that is matched to the shape and size of the contact section or the metal plate. The socket contact section is preferably connected to the socket plug element in a latching manner via a releasable latching connection.

The socket contact section is preferably formed from a spring steel. The socket contact section preferably has a resilient spring section in such a way that the socket plug element can be latched to the contact section by the spring section protruding from the socket plug element by a resilient snapping of the spring section into a contour or recess on the socket plug element. The first contact point is preferably also formed on a resilient section, with which a preload is provided, via which a secure galvanic contact between the first contact point and the second contact point, which belongs to the contact section on the plug-in section, can advantageously be set up. This is done when the male part and the socket are in the connected state.

The socket is preferably made of a metal material such as. B. a casting. The socket plug element, which is part of the electrification arrangement, consists, for. B. made of a plastic material. The socket plug element with the contact section can be plugged onto the socket. On the outside of the socket there is an insertion contour for inserting the socket plug element. The socket plug-in element can preferably be attached to the socket via a sliding fit. The first contact section is electrically insulated from the metallic socket by being received in the socket plug element when the socket plug element is attached to the socket. When the first contact section is electrically energized, the socket remains de-energized.

The first contact section is preferably releasably insertable on the socket plug element. The socket plug-in element has, in relation to the state attached to the socket, a front opening or open side, preferably a side open axially at the rear. The open side takes place from the outside, e.g. B. on the back of the support structure, an electrically conductive connection of the first contact section, for example via an electrical supply line reaching the socket, such as a cable of a power grid. The cable preferably extends through the open side and is electrically conductively connected to at least one conductive wire of the cable at the contact section, e.g. B. soldered.

To provide a separate two-pole electrical supply, there are two recesses on the socket for a socket plug element that can be used appropriately, each with a contact section.

According to a preferred variant, the contact section of the electrification arrangement is present on the plug-in part on a plug-in part plug-in element, the plug-in part plug-in element consists of an electrically insulating material. The plug-in part plug-in element is a separate component from the plug-in part, which is preferably made of a metal material, and can preferably be fitted thereon. To provide a separate two-pole electrical supply, there are two recesses on the plug-in section for a plug-in part plug-in element that can be used appropriately.

The plug-in part contact section is formed, for example, from a thin metal plate which can be inserted into a seat on the plug-in part plug-in element that is matched to the shape and size of the contact section. The plug-in part contact section is preferably connected in a latching manner to the plug-in part plug-in element via a releasable latching connection.

The plug-in part plug-in element and the recess on the outside of the plug-in section are designed to be coordinated with one another, so that the plug-in part plug-in element is received in the recess completely or at least almost completely. An edge of the plug-in part plug-in element preferably extends to an outside of the plug-in section or protrudes slightly from it. The contact section of an insert part plug-in element is preferably present on the plug-in part between opposite edges of the plug-in part plug-in element lying somewhat lower than the respective outside of the edges. The contact portion is preferably made of a z. B. strip-shaped metal plate formed with an angled inwardly bent front end. When the plug-in part plug-in element is in the inserted state, the bent front end extends radially somewhat inward into a region of the opening or the cavity of the plug-in section. At the bent front end, an electrical line is preferably connected z. B. soldered a wire of an electrical cable line.

Another advantage arises from the fact that the first contact point and / or the second contact point are designed as a resilient contact point. The first contact point and / or the second contact point are preferably present on a resilient section of the relevant contact section. This ensures a safe galvanic connection between the two contact points through an effective spring preload.

Finally, it is advantageous that a positioning arrangement acting between the receptacle of the socket and the plug-in section of the plug-in part is formed, so that a position specification is set up between the plug-in section of the plug-in part and the socket in the circumferential direction to the plug-in axis. It is therefore only possible in exactly one circumferential relative position of the socket and the plug-in part to establish the connection state of the plug-in device. Incorrect polarity of the electrical connection or supply of the electrical consumer that can be set up with the electrification arrangement can thus be avoided. In this way, in particular, dangerous situations and / or an electrical short circuit or damage to, for example, a transformer of the electrification arrangement can be excluded.

The positioning arrangement is designed separately or preferably in combination with the anti-rotation device. The positioning arrangement or the anti-rotation device comprises, for example, a securing contour formed between the jacket region of the receptacle and the jacket region of the insertion section. The security contour includes z. B. a first and a second groove, which differ in width, preferably in or on the outside of the jacket area of the plug-in section, and exactly two elevations matching the position of the grooves on the otherwise conical wall of the receptacle, with a first elevation the jacket area of the socket, which in the connected state fits into the first groove and with a second elevation on the socket, which in the connected state fits into the second groove. The plug connection in the connected state of socket and plug-in part is only possible in exactly one rotational relative position of socket and plug-in part, which ensures the correct polarity of electrification.

It is also advantageous that magnetic means are provided to increase a holding force when the plug-in device is connected.

With magnetic means, in particular with permanent magnets attached to the socket and to corresponding sections of the plug-in part, the holding force can be increased in the connected state without problems and without complications. In particular, it is advantageous that the magnetic means comprise a first magnetic part in a frontal region of the insertion section in the insertion direction and a second magnetic part provided with a polarity opposite to the magnetic polarity of the first magnetic part on a bottom of the receptacle.

Finally, the invention extends to an arrangement for the presentation of goods with an insertion device according to one of the embodiments described above. The goods presentation arrangement can thus advantageously be provided with an electrical consumer which can be supplied with electricity via the plug-in device, inconspicuously or not visually from the outside, in a safe and space-saving manner. The electrical consumer is, for example, part of a lighting device for illuminating the goods on display, for example with a light source such as B. an LED light source.

A part of the goods presentation arrangement can preferably be attached or fastened to the attachment section of the insert part.

Fig. 1 shows an insertion device 1 according to the invention in a connected state. The plug-in device 1 is attached to a support structure 3 such. B. a wall element 4 (s. Fig. 2 ) or anchored to a profile rail. The plug-in device 1, which is used for a device or arrangement 2 for the presentation of goods (s. Fig. 7 ) is provided comprises a bushing 5 that can be attached to the support structure 3, a bushing that is separate from the bushing 5

Insertion part 6, a slip-on ring 7 and an electrification arrangement 8.

The plug-in part 6 has a plug-in section 9 and an attachment section 10, the plug-in section 7 being insertable into a cavity-forming receptacle 11 of the socket 5 in an insertion direction P1 along an insertion axis L until the connection state of the plug-in device 1 is reached. In the connected state, the plug-in part 6 and the socket 5 are detachably connected to one another, with a comparatively high holding force acting against the detachment of the plug-in part 6 completely plugged into the socket 5. A socket base 5a of the socket 5 is closed.

The insertion section 9 comprises an end region 12 and an outer jacket region 13, which are present inside the receptacle 11 in the connected state. The hollow receptacle 11 of the socket 5 also has a front area 14, which is located in front in the insertion direction P1, and an inner jacket area 15. In the connected state, the jacket area 13 of the plug-in section 9 and the jacket area 15 of the receptacle come into contact with one another. The jacket areas 13 and 15 are preferably designed as conical surfaces that are matched to one another. These or the respective surfaces of the jacket areas 13 and 15 come into flat contact in the connected state. The conical surfaces of the jacket regions 13 and 15 which are in abutment or contact with one another in the connected state provide the best possible or optimized form fit. This results in a connection between the plug-in part 6 and the socket 5 with optimized stability or with optimized play with a high holding force between the plug-in part 6 and the socket 5.

With the electrification arrangement 8, an electrical consumer 40 such. B. a lighting element 41 in the vicinity of the plug-in device 1 (s. Fig. 7 ) or on the arrangement 2 Electrically supplied for product presentation. In this case, an electrical connection is established between a part of the electrification arrangement 8 present on the socket 5 and a part of the electrification arrangement 8 present on the plug-in part 6. For this purpose, there is an electrically conductive contact through galvanic contact between a first contact point 17 of a contact section 16 (see Sect. Figure 11a ) of the electrification arrangement 8 at the socket 5 and a second contact point 19 of a contact section 18 (see FIG. Fig. 15 ) of the electrification arrangement 8 on the plug-in section 9 or the plug-in part 6.

The contact section 16 formed from an electrically conductive material such as a steel material on the socket 5 is attached to a socket plug element 20 (see Fig. Figures 10, 11 ) made of an electrically non-conductive material such. B. a plastic material detachably but locked.

The contact section 18, formed from an electrically conductive material or a steel material, on the plug-in section 9 is also attached to a plug-in part plug-in element 21 (see Fig. Figs. 13, 14 ) made of an electrically non-conductive material detachably but lockable.

The Fig. 9 shows the socket 5, which consists for example in one piece of a metallic cast part and is part of a plug-in device according to the invention. The associated contact section 16 with a socket plug element 20 can be attached to the socket 5.

For this purpose, two recesses 22, 23 radially opposite to the insertion axis L are formed on the socket 5 on a wall 25 of the socket 5 protruding at the rear on a flange section 24 of the socket 5. The recesses 22, 23 are each designed to match the socket plug-in element 20. As a result, two socket plug-in elements 20, each with a contact section 16 present thereon, can be plugged onto socket 5. In the plugged state of the socket plug-in elements 20 these are self-retaining by z. B. Frictional effects attached to the socket 5. A pin 26 protruding on the end face on the two socket plug-in elements 20 engages with friction in a corresponding respective bore 27 in the flange section 24.

On the inside, the wall 25 forms the jacket area 15 of the receptacle 11. With each recess of the recesses 22, 23, an opening 28, 29 is formed in the wall 25 and thus in the jacket area 15. A section of the respective contact section 16 engages through each opening 28, 29, the section extending through having the contact point 17. With the two contact sections 16, two different electrical poles are thus provided with or at the contact points 17, which are assigned to the part of the electrification arrangement 8 which is present on the socket 5. The two contact points 17 protrude radially inward from the insertion axis L to the jacket area 15 of the receptacle 11 or lie radially further inward than the jacket area 15, at radially opposite positions within the receptacle 11. There the contact points 17 come into contact with the respective associated Contact point 19 of the relevant contact section 18 on the insertion section 19.

For the respective contact sections 18 with the plug-in part plug-in element 21 on the plug-in section 9, two radially opposite recesses 30 and 31 are formed in the jacket area 13 or on an outside of the plug-in section 9. The recesses 30, 31 are each designed to match the plug-in part plug-in element 21. As a result, two plug-in part plug-in elements 21, each with a contact section 18 present thereon, can be plugged into or inserted into the plug-in part 6 or the plug-in section 9. When the plug-in part plug-in elements 21 (see Fig. Fig. 4, 6 ) these are attached to the plug-in section 9 in a self-retaining manner.

How in particular Figures 8 and 8a made clear are im Connection state, the first contact point 17 in the jacket region of the socket 5 and the second contact point 19 in the jacket region of the plug-in section 9 with one another in electrical contact.

The electrification arrangement 8 also comprises an electrical cable line 32 such as a cable line with two line cores 33 and 34, the line cores 33 and 34 serving to provide different electrical poles or an electrical plus pole and an electrical minus pole. Over the back of the support structure 3, a partial length 33a of the line wire 33 leads from an electrical supply (not shown) to one of the two socket-side contact sections 16. With this contact section 16, a conductive wire of partial length 33a insulated to the outside is the line wire 33 galvanically connected, for example soldered on. A partial length 34a of the line wire 34 from the electrical supply to the other of the two socket-side contact sections 16 also leads over the back of the support structure 3. A conductive wire of partial length 34a of the line wire 34 is galvanically connected to this contact section 16, for example soldered.

The electrically conductive connection via the respective pairs of contact points 17 and 19 is continued up to a partial length 33b of the line core 33 and a partial length 34b of the line core 34. The partial lengths 33b and 34b lead from a free end of the attachment portion 10 through a central cavity 35 of the Plug-in part 6 up to a respective associated contact section 18 of the two plug-in section-side contact sections 18. A conductive wire of partial length 34a of line core 34 is galvanically connected to one contact section 18, for example soldered. A conductive wire of partial length 33b of line core 33 is galvanically connected to the other contact section 18, for example soldered.

For the releasable, for example resilient, latching of the contact section 16 on the socket plug element 20, the contact section 16 has two spring tabs 36 which are bent over on a strip of sheet metal and which snap into a contour 37 on the socket plug element 20 when the contact section 16 is in the correct state of insertion on the socket plug element 20.

Correspondingly, for the releasable, for example resilient, latching of the contact section 18 on the plug-in part plug-in element 21, the contact section 18 has a spring tab 38 which is bent on a strip of sheet metal and which engages in a contour 39 on the plug-in part plug-in element 21 when the contact section 18 is in the correct state of insertion on the plug-in part plug-in element 21 .

To prevent rotation and to ensure the correct polarity of the electrical connection between the socket side of the plug-in device 1 and the plug-in part side of the plug-in device 1, there are two elongated, rectangular cross-sectioned webs 42, 43 extending in the direction of the plug-in axis L and projecting inward in the jacket area of the receptacle 11 (see Fig. Fig. 7 ). The two webs 42, 43 have a different width from one another. Two grooves 44 and 45, each with a different width, are formed in a corresponding width or orientation and position on the outside in the jacket area of the insertion section 9 (see FIG. Fig. 12 ).

To further increase a holding force in the connected state of the plug-in device 1, a magnet arrangement 46 is also provided (see Fig. Figures 8, 8a ). The magnet assembly 46 comprises magnetic means with the socket 5 assigned or therein in a blind hole z. B. glued-in permanent magnets 47 and a further permanent magnet 48 assigned to the plug-in part 6, which is also fixed in a blind hole at a front end or the end region 12 on the plug-in section 9 is appropriate. The magnet assembly 46 is in the Figures 8 and 8a indicated, the outlines of the permanent magnets 47 and 48 being shown in dashed lines. The magnetic pole of the permanent magnet 47 is opposite to the magnetic pole of the permanent magnet 48, so that in the connected state the permanent magnets 47 and 48 are in attractive contact with each other or over a comparatively very small gap with e.g. B. a gap distance of less than a millimeter from each other.

The force that attracts the plug-in part 6 in the plug-in direction P1 with the magnet arrangement 46 acts on the front side of the plug-in part 6, so that in addition to the existing positive or frictional connection, the plug-in part 6 is held firmly in the socket 5 by the magnetic force provided by the permanent magnets 47 and 48 .
