Definitions
- Connector for fastening a first component to a second component Connector for fastening a first component to a second component, connector arrangement, component arrangement, component connection and use of a connector
- the invention relates to a connector for fastening a first component to a second component.
- One of the first and second components has a recess for receiving the connector.
- the connector comprises a base body which is delimited by a base surface, a cover surface and a lateral surface.
- the invention is directed to a connector assembly with such a connector.
- the invention is further directed to a component arrangement comprising a component with a recess open on one side and such a connector.
- the invention also relates to a component connection comprising a first component, a second component, a fastening means and a connector.
- the invention is also directed to a use of a connector.
- Such connectors and the connector arrangements, component arrangements and component connections realized with them are known from the prior art. In particular, they are used to connect components made of wood.
- the aim is always to be able to create a stable mechanical component connection using the connector.
- the connector should be simple to construct and easy to handle.
- TOP Component connection the simply constructed connector and the easy handling of the connector is a conflict of objectives.
- the problem is solved by a connector for fastening a first component to a second component.
- One of the first and second components has a recess for receiving the connector.
- the connector comprises a base body which is delimited by a base surface, a cover surface and a lateral surface.
- the lateral surface defines a lateral outer contour of the connector.
- a recess extends from the cover surface and a guide channel with a guide channel central axis extends from the recess to the lateral surface of the base body.
- the guide channel central axis is inclined with respect to a base body axis that is perpendicular to the base surface and/or perpendicular to the cover surface.
- an inclined orientation refers to an orientation that is neither parallel nor perpendicular.
- the guide channel central axis is therefore neither parallel nor perpendicular to the base surface and/or to the cover surface. It is understood that the base surface and the cover surface can run parallel but do not have to. In the event that the base surface and the cover surface are arranged in parallel, the base body axis is perpendicular to both the base surface and the cover surface.
- the guide channel is suitable for guiding a fastening means or a tool, in particular a drill, and/or for receiving it at least in sections.
- the guide channel preferably has a circular cross-section.
- Such a connector which essentially comprises a base body with a recess and a guide channel, is structurally very simple.
- the lateral surface defines a lateral outer contour of the connector.
- the connector therefore comes without any protruding edges laterally relative to the base body.
- the fact that the lateral surface defines the lateral outer contour is to be understood in such a way that the entire lateral outer contour is determined by the lateral surface.
- the connector comprises only a single component.
- the fact that the guide channel starts from the recess and the guide channel central axis is inclined relative to the base body axis means that both a fastening means and a tool can be easily inserted into the guide channel.
- the recess creates the necessary freedom of movement for this. In other words, the connector is comparatively easy to handle.
- the inclined guide channel central axis has the effect that a stable mechanical component connection can be formed by means of the connector.
- a fastening means can be inserted into the guide channel at least in sections. Due to the inclined arrangement of the guide channel central axis, a comparatively large coupling area results between the fastening means and the first component and between the fastening means and the second component.
- the base surface, the cover surface and the shell surface together define an outer contour of the connector.
- Such a connector is particularly simple in construction.
- an outer contour can also be understood as an envelope contour that envelops the connector.
- a lateral outer contour can be understood as a lateral envelope contour that envelops the connector laterally, i.e. from the side.
- the connector Due to the fact that the lateral surface defines a lateral outer contour of the connector, the connector has no elements that, in a view perpendicular to the cover surface, lie outside an outer contour of the cover surface, i.e. protrude beyond the outer contour of the cover surface. Accordingly, in the view perpendicular to the cover surface, the outer contour of the cover surface also defines a lateral outer contour or a lateral envelope contour of the connector.
- the guide channel central axis can be inclined relative to the surface at an intersection point of the guide channel central axis and the shell surface.
- intersection point of the guide channel central axis and the shell surface is a virtual intersection point. This is because the shell surface is penetrated by the guide channel in the area of the intersection point. The intersection point is therefore not physically present, but only virtual. This results in the effects and advantages already explained.
- the guide channel center axis is inclined towards the base surface at the intersection point between the guide channel center axis and the lateral surface. This means that the intersection point between the guide channel center axis and the lateral surface is closer to the base surface than points on the guide channel center axis that are closer to the recess starting from this intersection point.
- This has the effect that the connector is pulled towards a base of the recess of the first component or the second component when the connector is arranged in the recess and the first component and the second component are fastened to one another using a fastening means arranged in the guide channel. In this way, the stability of the connection between the first component and the second component is further increased.
- At least one holding means is arranged on the outer surface, which is designed to hold the connector in the recess of the first or second component.
- a plurality of holding means are arranged on the outer surface.
- the holding means can be designed as a holding rib or groove.
- each of the holding means is designed as a holding rib or groove.
- the holding ribs or grooves serve to clamp the base body of the connector to a outer surface of the recess.
- the holding means can be designed as a holding lamella. In the event that a plurality of holding means is provided, each of the holding means is designed as a holding lamella.
- each of the holding means is designed as a holding lamella.
- the retaining lamellae serve to clamp the base body of the connector to the outer surface of the recess.
- the retaining lamellae can be elastically deformed, for example bent, when the connector is inserted into the recess of the first or second component. All variants have the effect that the connector is reliably held in the recess on the first or second component.
- the guide channel can have a chamfer at its recess-side end, i.e. at the end of the guide channel that faces the recess.
- the chamfer preferably runs completely around a circumference of the guide channel. Such a chamfer makes it easier to insert a fastening means and/or a tool into the guide channel. This makes handling the connector even easier.
- the basic body can have the shape of a cylinder or the shape of a truncated pyramid or the shape of a truncated cone.
- a cylinder is understood as a general cylinder.
- the basic body can therefore have a shape that results from a flat, closed curve being moved along a straight line.
- the straight line can be oriented in any direction to the curve.
- the straight line is perpendicular to a surface defined by the closed curve.
- the cylinder is also called a straight cylinder.
- the basic body in the variant in which it has the shape of a truncated pyramid can have a base of any shape.
- the base is quadrangular, for example rectangular or square.
- the base of the truncated pyramid is hexagonal.
- the truncated cone can have a base of any shape. Preferred examples are circular or elliptical bases.
- the basic body is structurally simple.
- a base body designed in this way can provide a comparatively large surface area via which a holding force can be transmitted to the component that has the recess in which the connector is arranged.
- Connectors shaped in this way serve to create a stable mechanical component connection.
- an outer contour of the connector has the shape of a cylinder or the shape of a truncated pyramid or the shape of a truncated cone.
- the guide channel central axis can form an angle of between 30 degrees and 85 degrees with the base body axis. This means that the guide channel central axis forms an angle of between 5 degrees and 60 degrees with the base surface and cover surface on which the base body axis is perpendicular. In one example, the guide channel central axis and the base body axis form an angle of 45 degrees. In another example, the guide channel central axis and the base body axis form an angle of 60 degrees.
- a guide channel central axis inclined in this way has the advantage that a fastening means and/or a tool can be easily inserted into the guide channel. In addition, as already mentioned, a stable mechanical connection is obtained because, due to the inclination, a coupling section between the fastening means and the first component and/or the second component is comparatively large.
- the guide channel center axis is inclined relative to the base body axis perpendicular to the base surface and/or perpendicular to the cover surface and/or relative to the lateral surface in such a way that an imaginary extension of the guide channel that extends through the depression starting from the cover surface does not intersect the base body.
- a projection of a cross section of the guide channel that occurs along the guide channel center axis in the direction of the depression starting from the cover surface does not touch or intersect the base body.
- a fastening means and/or a tool can be introduced into the guide channel particularly easily.
- the guide channel center axis is arranged perpendicular to the base surface and/or perpendicular to the cover surface and/or to the
- the outer surface is inclined in such a way that an imaginary extension of the guide channel along the guide channel center axis in the direction of the side of the connector opposite the guide channel, i.e. in the direction of the recess, only intersects the plane of the cover surface of the connector.
- the plane of the cover surface is limited by an outer contour of the cover surface. In this way, a fastening device can be installed particularly easily when the connector is inserted into the recess for receiving the connector.
- the recess has a flat wall surface.
- the guide channel starts from the flat wall surface.
- the guide channel center axis is perpendicular to the flat wall surface.
- a wall surface is structurally and technically simple to manufacture.
- a flat wall surface is particularly suitable as a contact surface for a fastening device that is arranged at least in sections in the guide channel.
- the fastening device is a screw
- a screw head can be placed on the wall surface in this context. In this way, comparatively large forces can be transmitted between the connector and the fastening device. This serves to ensure a stable mechanical component connection.
- the recess has a varying depth measured along the base body axis.
- a deepest point of the recess is located adjacent to the guide channel.
- the depth of the recess is not constant.
- a comparatively large depth can therefore create the necessary freedom of movement for a fastening device or a tool to be arranged in the guide channel. Elsewhere, a smaller depth can be sufficient to Fasteners or tools can be arranged in the guide channel. Overall, this creates a stable mechanical connector that is still easy to handle. The latter particularly applies to inserting the fastener or tool into the guide channel.
- the recess has a concavely curved recess base.
- the concavely curved recess base merges without edges into one or more side surfaces of the recess.
- the concavely curved recess base offers the necessary freedom of movement within the recess for fastening means and/or tools that are to be introduced into the guide channel.
- the curvature is advantageous with regard to a force or stress curve within the connector, since stress and force peaks are avoided, particularly in comparison to a square design. The mechanical stability of the connector is therefore improved in this way.
- the concavely curved recess base surface can be a section of a circular cylinder surface, with a radius of the circular cylinder surface being larger than a radius of the guide channel.
- a recess base surface is structurally simple and can be produced comparatively easily and inexpensively using known manufacturing processes.
- a central axis associated with the circular cylinder surface coincides with the central axis of the guide channel.
- the guide channel and the section of the recess base designed as a circular cylinder surface are arranged coaxially. This leads to a comparatively simple structure of the connector.
- the base body has a length measured perpendicular to the base body axis and a width measured perpendicular to the base body axis and perpendicular to the length.
- the length and the width are the same size.
- Such a base body is relatively compact.
- the base and/or the top surface can be circular or polygonal.
- a special case of polygonal is square.
- the term polygonal also includes polygon shapes in which the corners of the polygon are rounded.
- the base and top surfaces preferably have the same shape. Overall, all variants result in a structurally simple connector.
- the base body can also have a length measured perpendicular to the base body axis and a width measured perpendicular to the base body axis and perpendicular to the length, with the length being greater than the width.
- Such a base body is therefore elongated. In this way, comparatively large areas can be created for force transmission between the connector and the first component or second component in whose recess the connector is inserted.
- the elongated shape also offers a certain amount of space for the recess.
- the recess can therefore be designed in such a way that a fastening device and/or a tool can be inserted particularly easily into the guide channel.
- the guide channel starts from a narrow side of the casing surface. This means that a comparatively large amount of space is provided for the recess.
- the base surface and/or the top surface can be polygonal or elliptical or composed of at least two geometric elements.
- a special case of polygonal is rectangular.
- the term polygonal also includes polygon shapes in which the corners of the polygon are rounded.
- a radius of curvature of the rounded corners can, for example, correspond to half the width of the rectangle.
- the base surface and/or the top surface is composed of, for example, two or more intersecting circular surfaces, each of which has its center on a common alignment line.
- the base surface and the cover surface has the same shape. Overall, all variants result in a structurally simple connector.
- a connector arrangement which comprises a connector according to the invention and a fastening means.
- the fastening means is arranged at least in sections in the guide channel.
- the fastening means is suitable for being coupled to the first component and/or to the second component.
- the fastening means can be arranged loosely in the guide channel or held captive in the guide channel.
- a captive element can be provided which is separate from the base body and the fastening means.
- the guide channel can be matched to the fastening means, for example in terms of its diameter, so that the fastening means is held captive.
- a securing means can be provided within the guide channel which serves to hold the fastening means captive.
- the fact that the fastening means is arranged in the guide channel means that the connector is suitable for connecting two components without additional elements.
- the fastener is a screw.
- Such fasteners have proven themselves in terms of their handling and mechanical stability. In addition, they can be operated using standard tools.
- a component arrangement which comprises a component with a recess open on one side and a connector according to the invention.
- the connector is arranged in the recess.
- the shape of the recess corresponds to the shape of the base body of the connector, so that a lateral surface of the base body and a lateral surface of the recess run adjacently.
- Such a recess can also be referred to as a pocket or a blind hole.
- the base surface of the connector preferably rests against a bottom surface of the recess.
- the cover surface of the connector is preferably arranged flush with the side of the component in which the recess is arranged.
- the recess can, like the connector, have the shape of a cylinder, a truncated pyramid or a truncated cone.
- the recess narrows along its depth direction. It goes without saying that the recess must always be slightly larger than the connector that is inserted into it.
- the recess is therefore structurally just as simple as the connector.
- the connector can be easily inserted into the recess due to the corresponding shapes of the connector and recess.
- the component can have a contact surface for contact with another component.
- the recess which is open on one side, can be closed in a direction towards the contact surface.
- a section of the component is arranged between the recess and the contact surface.
- this section lies between the connector and the other component. This section thus serves to transmit force between the component and the connector.
- the connector can be reliably supported on this section. High forces can be transmitted. This allows a stable mechanical connection to be created.
- the component connection comprises a first component, a second component, a fastening means and a connector according to the invention.
- the first component has a recess that is open on one side.
- the connector is arranged in the recess.
- the shape of the recess corresponds to the shape of the base body of the connector, so that a lateral surface of the base body and a lateral surface of the recess run adjacently.
- the fastening means is arranged at least in sections in the guide channel of the connector and engages in the second component. The fastening means can also engage in the first component, namely in that section of the first component that lies between the connector and the second component.
- a receiving channel for the fastening means can be provided in the area of the first component that lies between the connector and the second component, which coaxially to the guide channel of the connector.
- the fastening means does not engage in the first component in the sense that it would directly introduce forces into a wall of the receiving channel or absorb them from the wall of the receiving channel.
- a stable and reliable connection of the first component and the second component is achieved by the fastening means engaging in the second component and being coupled to the first component via the connector.
- both the connector and the recess for receiving the connector are of a comparatively simple design, such a component connection can be easily produced.
- the first component and the second component are made of wood.
- the first component can therefore be a wooden component.
- the second component can also be a wooden component.
- both the first component and the second component are panels.
- the component connection can be designed as a corner joint or a flat joint.
- the first component can have a first contact surface and the second component a second contact surface.
- the first contact surface and the second contact surface can contact each other.
- the recess which is open on one side, can be closed in a direction towards the first contact surface.
- a section of the first component is arranged between the recess and the second component. This section thus serves to transmit force between the first component and the connector. In other words, the connector can be reliably supported on this section. High forces can be transmitted. This allows a stable mechanical connection to be created.
- a position at which the fastening means emerges from the first contact surface is determined, among other things, by a distance between the connector and the first contact surface. This distance can be selected according to the application.
- fasteners can be used depending on the application. This affects, for example, the length of the fastener.
- the fastening means is designed as a screw. More preferably, the fastening means is designed as a wood screw. In this context, in a wood screw, an end opposite the screw head is pointed. In addition, in a wood screw, a screw core body, i.e. the elongated section of the screw on which an external thread is arranged, can have a conical or tapered section.
- the object is achieved by using a connector according to the invention as a drilling template.
- the guide channel serves to guide a drill.
- the connector is first inserted into the recess of the first component and then the drill is guided in the guide channel.
- a receiving channel can be made between the recess in which the connector is inserted and the first contact surface of the first component, through which the fastening means, for example the screw, can be pushed.
- only a core hole can be made, which also extends between the connector of the first contact surface.
- the core hole differs from the receiving channel in that the core hole is designed so that a force transmission takes place between a wall of the core hole and the fastening means.
- a component connection according to the invention can thus be produced by providing a first component, a second component and a connector in a first step.
- the first component may already have a recess for the connector, or this recess can be created during the first step.
- the connector is inserted into the recess.
- the connector can be used as a drilling template. This means that a drill is guided in the guide channel of the connector to create a hole in the first component. As already explained above, this hole can be designed as a core hole or as a receiving channel.
- a fastening device for example a screw, can be inserted into the guide channel and connected to the second component and/or the first component.
- the fastening means is a screw or another fastening means that can be operated using a tool
- a suitable tool can also be inserted at least partially into the recess to connect the fastening means to the second component and/or the first component in order to interact with the fastening means within the recess.
- a screwdriver or a hexagon wrench can be used in this context.

- the first contact surface 22 has a smaller surface area than the second contact surface 26, in the example shown the first contact surface 22 is fully contacted by the second contact surface 26, whereas the first contact surface 22 only contacts a section of the second contact surface 26.

- the base area 36 is polygonal. More precisely, the base area 36 has the shape of a rectangle with rounded corners. A corner radius corresponds to half the width of the rectangle.
- the top surface 38 has the same shape as the base surface 36, i.e. it is also polygonal.
- the cover surface 38 defines an upper outer contour or upper envelope contour of the connector 30.
- the base surface 36 defines a lower outer contour or lower envelope contour of the connector 30.
- the lateral surface 40 defines a lateral outer contour or lateral envelope contour of the connector 30.
- the base surface 36, the cover surface 38 and the lateral surface together define an outer contour or envelope contour of the connector 30.
- the base body 34 has a length LG measured perpendicular to the base body axis G.
- the length of the base body corresponds to the longer extension of the polygonal base surface 36 and the polygonal cover surface 38.
- the base body 34 has a width BG measured perpendicular to the base body axis G and perpendicular to the length LG.
- the direction of the width BG thus corresponds to the shorter extension of the polygonal base surface 36 and the polygonal cover surface 38.
- the length LG of the base body 34 is greater than the width LG of the base body 34.
- a height HG of the base body 34 is measured along the base body axis G.
- the base body 34 also has a recess 42 which extends from the cover surface 38.
- the recess 42 is elongated and extends essentially along the direction of the length LG of the base body 34.
- the recess 42 has a flat wall surface 44.
- the flat wall surface 44 delimits the recess 42 on one narrow side.
- the narrow side is inclined relative to the base body axis G, for which purpose the flat wall surface 44 is rotated about an axis running parallel to the width direction of the base body 34.
- the recess 42 is delimited by a concavely curved recess base surface 46.
- the concavely curved recess base surface 46 is formed as a section of a circular cylinder surface.
- a central axis belonging to the section of this circular cylinder surface is perpendicular to the flat wall surface 44.
- the concavely curved depression base surface 46 extends such that the depression 42 has a varying depth TV measured along the base body axis G (see Figure 2).
- the depth TV of the depression 42 is zero at an end of the depression 42 facing away from the flat wall surface 44. A deepest point of the depression 42 is thus adjacent to the flat wall surface 44.
- the base body has a guide channel 48 which starts from the flat wall surface 44 and extends to the casing surface 40.
- the guide channel 48 thus extends from a narrow side of the lateral surface 40.
- the guide channel 48 has a constant, circular cross-section.
- the guide channel 48 has a guide channel center axis M which is oriented perpendicular to the flat wall surface 44.
- the guide channel center axis M is inclined relative to the base body axis G.
- an angle enclosed by the guide channel center axis M and the base body axis G is 70 degrees.
- an angle enclosed by the guide channel center axis M and the lateral surface 40 is also 70 degrees.
- the point of intersection between the guide channel center axis M and the lateral surface 40 is used as a reference.
- the guide channel center axis M is inclined in the direction of the base surface 36. This means that the intersection point between the guide channel center axis M and the lateral surface 40 is closer to the base surface 36 than points on the guide channel center axis M which, starting from this intersection point, are closer to the recess 42.
- the central axis assigned to the circular cylinder surface and the guide channel central axis M coincide.
- a radius of the circular cylinder surface i.e. a radius of the concavely curved recess base surface 46, is larger than a radius of the guide channel 48.
- a total of four retaining holes 50 are arranged in the cover surface 38. One of the retaining holes 50 is positioned in the area of a corner of the polygonal cover surface 38.
- All four retaining holes 50 are designed as blind holes.
- the retaining holes 50 serve to hold the cover cap 32 on the connector 30.
- the cover cap 32 accordingly comprises a substantially plate-shaped cover element 52, from which a total of four retaining pins 54 protrude.
- the plate-shaped cover element 52 has essentially the same shape as the cover surface 38 and the base surface 36.
- the cover element 52 is therefore also polygonal in shape, and in the embodiment shown it is designed as a rectangle with rounded corners.
- a width of the cover element 52 is selected such that it is slightly larger than the width BG of the connector 30.
- a length of the cover element 52 is selected such that it is slightly larger than the length of the connector 30.
- the base body 34 further comprises a cavity 53 extending from the base surface 36.
- the cavity 53 serves to reduce the amount of material required to manufacture the connector.
- the connector is made of a plastic material.
- the connector 30 is arranged in the recess 14 of the first component 12, which is open on one side.
- the shape and size of the recess 14 and the connector 30 are coordinated such that the base surface 36 of the connector 30 rests against a bottom of the recess 14.
- the cover surface 38 of the connector is arranged essentially flush with the flat side 18 of the first component 12.
- the outer surface 40 of the connector 30 lies essentially against a outer surface of the recess 14 that is open on one side.
- the outer surface 40 of the connector 30 and the outer surface of the recess 14 that is open on one side run adjacent to one another.
- a section of the lateral surface 40 has grooves 56.
- only a single exemplary groove 56 is provided with a reference symbol in the figures.
- the combination of the first component 12 and the connector 30, which is arranged in the recess 14 open on one side, can also be referred to as component arrangement 58.
- the component connection 10 also comprises a fastening means 60 (see in particular Figure 2).
- connector 30 The combination of connector 30 and fastening means 60 can also be referred to as a connector arrangement.
- the fastening means 60 is a self-tapping screw.
- the screw is screwed into the second component 30 with a tip-side section.
- the tip-side section of the screw or, more generally, the fastening means 60 engages in the second component.
- a head of the fastening means 60 arranged opposite the tip of the fastening means 60 rests against the flat wall surface 44.
- a central section located between the head and the tip of the fastening means 60 is arranged partly in the guide channel 48 and partly in a receiving channel coaxially connected to the guide channel.
- the receiving channel is designed as a through hole 62 in the first component 12.
- the fastening means 60 here the screw, is thus screwed into the second component 20 in such a way that the head, in this case the screw head, rests under tension on the flat wall surface 44 and thereby applies force to the connector 30 in the direction of one end of the recess 14, which is open on one side and faces the second component 20.
- the head in this case the screw head
- the connector 30 in the direction of one end of the recess 14, which is open on one side and faces the second component 20.
- Figure 6 shows a connector 30 according to an alternative embodiment. In the following, only the difference compared to the connector 30 according to the embodiment from Figures 1 to 5 will be discussed.
- Figure 7 shows a component connection 10 according to a further embodiment. Here, only the differences compared to the component connection from Figures 1 and 2 are discussed.
- the component connection 10 according to Figure 7 comprises a fastening means 60, which here again is designed as a self-tapping screw, which is considerably longer than the fastening means 60 of the component connection from Figures 1 and 2.
- the fastening means 60 must always be selected to be long enough so that it can engage in the second component 20 over a desired length when it is arranged in the guide channel 48 and the through hole 62 in such a way that the head of the fastening means 60 rests against the flat wall surface 44.
- a further difference between the component connection 10 according to Figure 7 and the component connection 10 according to Figures 1 and 2 is that the connector 30 according to Figure 6 is used in the component connection 10 according to Figure 7. Accordingly, the component connection 10 according to Figure 7 does not have a cover cap 32.
- a length LG is 33 mm and a width BG is 10 mm.
- all dimensions specified for the connector 30 or the recess 14 that is open on one side are to be understood as nominal dimensions.
- combinations of connectors 30 and recesses 14 can be created on the basis of these nominal dimensions, which form a press fit, a clearance fit or a transition fit.
- it is also possible to select the toleration so that the connector 30 can be used for several applications. In other words, the toleration can also be provided independently of the application.
- connectors 30 and associated recesses 14 can also have dimensions that are smaller than the dimensions given in the table above or larger than the dimensions given in the table above.
- the ratio between the width BG and the length LG of the base body 34 of the connector 30 is preferably in the range of 0.25 to 0.35. A preferred ratio is 0.3.
- the height HG can be 12 mm as standard. The height HG is therefore independent of the application. Alternatively, the height HG can be selected to suit the application.
- Figure 8 shows a connector 30 according to a further embodiment.
- the connector of Figure 8 has a base body 34 which has the shape of a truncated pyramid.
- the base surface 36 and the cover surface 38 of the connector 30 are oriented parallel, but the base surface 36 is significantly smaller than the cover surface 38.

- the guide channel center axis M is inclined in the direction of the base surface 36, as in the previous embodiments.
- the lateral surface 40 does not run parallel to the base body axis G. This applies to all side surfaces of the truncated pyramid-shaped base body 34, which together form the lateral surface 40.
- an inclination of the guide channel central axis M relative to the section of the lateral surface 40 through which it penetrates differs from the inclination of the guide channel central axis M relative to the base body axis G.
- the guide channel center axis M can also be perpendicular to the section of the lateral surface 40 through which it passes.
- the guide channel center axis M can therefore also have no inclination relative to this section of the lateral surface 40. This variant is shown in Figure 8.
- the connector according to Figure 8 has no grooves 56 on its outer surface 40.
- the recess 14 which is open on one side must be adapted to the geometry of the connector 30. Accordingly, the recess 14 must also have the shape of a truncated pyramid.
- the recess 14 is preferably dimensioned such that the base surface 36 of the connector 30 contacts a bottom surface of the recess 14 when the connector 30 is inserted into the recess 14.
- cover surface 38 of the connector 30 runs flush with the flat side 18 of the first component 12 when the connector 30 is inserted in the recess 14.
- the lateral surface 40 of the connector 30 and the lateral surface of the recess 14 preferably run adjacently.
- a connector 30 according to another embodiment is shown in Figure 9.
- the connector of Figure 9 has a base body 34 which has the shape of a truncated cone.
- the base surface 36 and the cover surface 38 of the connector 30 are oriented parallel, but the base surface 36 is significantly smaller than the cover surface 38.
- both the base surface 36 and the top surface 38 are circular.

- the guide channel center axis M is inclined in the direction of the base surface 36, as in the previous embodiments. In the embodiment according to Figure 9, however, the lateral surface 40 does not run parallel to the base body axis G.
- an inclination of the guide channel central axis M relative to the lateral surface 40 differs from the inclination of the guide channel central axis M relative to the base body axis G.
- a point of intersection between the guide channel central axis M and the lateral surface 40 is taken into account.
- the guide channel center axis M can also be perpendicular to the lateral surface 40 at the intersection point between the guide channel center axis M and the lateral surface 40.
- the guide channel center axis M can therefore also have no inclination with respect to the lateral surface 40. This variant is shown in Figure 9.
- the connector according to Figure 9 has no grooves 56 on its outer surface 40.
- the recess 14 which is open on one side must be adapted to the geometry of the connector 30. Accordingly, the recess 14 must also have the shape of a truncated cone.
- the recess 14 is preferably dimensioned such that the base surface 36 of the connector 30 contacts a bottom surface of the recess 14 when the connector 30 is inserted into the recess 14.
- cover surface 38 of the connector 30 runs flush with the flat side 18 of the first component 12 when the connector 30 is inserted in the recess 14.
- the lateral surface 40 of the connector 30 and the lateral surface of the recess 14 preferably run adjacently.
- a method for producing a component connection 10 is explained below with reference to Figures 10 to 12.
- a first component 12 with a one-sided recess 14 and a second component 20 are provided. Furthermore, a connector 30 is provided, which in Figures 10 to 12 is, by way of example, the same connector as in Figures 1 to 5.
- the connector 30 can then be inserted into the recess 14 which is open on one side.
- the connector 30 is then used as a drilling template. This means that a drilling tool 64 is introduced into the guide channel 48 and, guided by the guide channel 48, the through hole 62 is produced in the first component 12, which connects the recess 14 to the first contact surface 22 (see Figure 11).
- a through hole 62 is manufactured for the fastening means 60. This means that the through hole 62 is dimensioned such that the fastening means 60 can be pushed through the through hole 62 essentially without resistance.
- a core hole can be made instead of the through hole 62.
- the core hole is characterized by the fact that the fastening means 60, which in this case is designed as a screw, can only pass through the core hole by rotating, ie by using the thread. It is therefore not possible to push the fastening means axially through the core hole.
- the connector 30 can also be used as a drilling template. It is only necessary to use a drilling tool 64 with a smaller diameter compared to the aforementioned alternative.
- the fastening means 62 in this case the screw, can be inserted into the guide channel 48 and into the through hole 62. Furthermore, the second component 20 must then be placed with the second contact surface 26 against the first contact surface 22 (see Figure 12).
- the fastening means 60 which in this case is a self-tapping screw, can be screwed into the second component 20.
- a screw tool is used on the head of the fastener 60.
- the fastening means 60 is guided through the guide channel 48 when screwing into the second component 20.
- the screwing tool can initially engage the head of the fastening means 60 outside the recess 42.
- the head of the fastening means 60 is at least partially arranged within the recess 42, so that the screwing tool engages the head of the fastening means 60 at least partially within the recess.
- the cover cap 32 can optionally be placed on the connector 30.
- the retaining pins 54 are inserted into the associated retaining holes 50. list of reference symbols
