Description

System comprising a plug contact carrier and at least one plug contact element, plug contact carrier, plug contact element and plug connector
Technical Field
The invention proceeds from a system of a plug contact carrier and at least one plug contact element, wherein the at least one plug contact element has at least one socket element and/or at least one pin element and/or at least one plug element for directly contacting a circuit board, and wherein the at least one plug contact element has a connection region which interconnects the contact regions, wherein the at least one plug contact element is positioned and fixed in the plug contact carrier in the connected state.
Background
According to one embodiment, the plug element for making direct contact has two contact feet which can be inserted into corresponding contact holes of the circuit board, so that the circuit board can be contacted only by inserting the plug element.
According to a further embodiment, the plug element for direct contact with the circuit board is oriented substantially perpendicularly with respect to the socket element and/or the pin element. Thus, there is sufficient space for joining and arranging the components to be connected.
The at least one plug contact element and the plug contact carrier are designed in the scope of the invention such that the plug contact element can be inserted into the plug contact carrier for connection with the plug contact carrier.
The invention further relates to a plug contact element for receiving in a plug contact carrier, wherein the plug contact element is designed to form the system described above; a plug contact carrier for accommodating at least one plug contact element, wherein the plug contact carrier is designed to form the system; and a plug connector, preferably a direct plug connector for contacting a circuit board, preferably via a plug connection, comprising a system of a plug contact carrier and at least one plug contact element and furthermore comprising a housing.
Plug connectors for electrically contacting at least two electronic components are known from the prior art. In particular, the contacting of the circuit board places high demands on the positioning and fixing of the current-carrying contact elements of the plug connector.
A plug contact element for connecting an electrical component to a circuit board is known from the prior art DE 202016105358U 1, wherein the plug contact element can be inserted into a plug contact carrier, and wherein the plug contact element is positioned in the contact carrier via a mounting frame and via a latching connection.
Furthermore, a plug connector is known from the publication DE 102013111571B 4, in which plug contact elements arranged in a plug contact carrier have soldering pins for connection to a circuit board, and in which the plug contact elements have fixing openings in the region of the contact sockets, which fixing openings fix the plug contact elements in the mounted state in interaction with corresponding projections of the plug contact carrier. However, such a design has the disadvantage that an incomplete engagement of the fastening opening influences the size of the contact opening of the contact socket and, for this reason, the contact quality.
Furthermore, it is known from the prior art to connect contact metal in the form of plug contact elements with the housing by means of thermal caulking in order to ensure a defined positioning. For this purpose, the plug contact elements must first be pre-positioned in order to thermally gap the plug contact elements in the correct position. This method has the disadvantage that additional complex process steps are required to produce the system described above. Furthermore, the method is subject to relatively large gaps between the individual components.
Disclosure of Invention
Starting from the cited prior art, the object of the invention is to specify a system of a plug contact carrier and at least one plug contact element, in which the plug contact element can be connected to the plug contact carrier and positioned and fixed in the plug contact carrier in a particularly simple manner. The object of the invention is also to specify a corresponding plug contact carrier, a corresponding plug contact element and a corresponding plug connector.
According to a first teaching, the above object is achieved by the system described above, which is composed of a plug contact carrier and at least one plug contact element, having the features of patent claim 1, in that the at least one plug contact element is fixed in the plug contact carrier by a latching connection, wherein the latching connection is arranged in the connection region of the plug contact element.
According to the invention, at least one plug contact element can be inserted into the plug contact carrier in a defined manner, wherein the plug contact carrier and the at least one plug contact element are designed such that the at least one plug contact element is fixed directly by the latching connection after insertion. Since the latching connection is arranged in the connection region of the plug contact element and therefore not in the contact region of the plug contact element, the latching connection has no influence on the contact region and in particular on the quality of the contact. Even an incomplete latching does not necessarily lead to a poorer contact quality.
As a result, the system according to the invention therefore ensures on the one hand a particularly simple connection of at least one plug contact element to the plug contact carrier and on the other hand an improved contact with further structural elements.
For example, the detent connection according to the invention is designed as a rear detent. In this case, the latching behind means that the latching takes place in the insertion direction behind a latching element or a latching counter-element arranged on the plug contact carrier.
According to a preferred embodiment, the at least one plug contact element has a latching element, in particular in the form of a latching nose or a latching hook, and the plug contact carrier has a latching counter-element, in particular in the form of a recess, wherein the latching element forms a latching connection with the latching counter-element in the inserted state of the plug contact element, and wherein the latching element is arranged in the connection region of the at least one plug contact element.
It is likewise conceivable for the plug contact carrier to have latching elements, in particular in the form of latching noses or latching hooks, which in the inserted state snap into latching counter-elements, in particular in the form of recesses, arranged on at least one plug contact element.
In particular, the latching element and the latching counter-element are preferably designed such that the latching element is elastically deformed and/or deflected during insertion, preferably by resetting of the latching counter-element. In the inserted state, the latching element has an original shape or position, whereby a latching connection is achieved.
According to a further preferred embodiment, at least one plug contact element is fixed in the plug contact carrier by exactly one latching connection. According to this embodiment, in addition to the latching connection, a further defined contact area, in particular in the form of a stop and/or a bearing surface and/or a guide surface, is optionally present between the at least one plug contact element and the plug contact carrier, wherein the defined contact area stabilizes the position of the plug contact element in the plug contact carrier.
A further advantageous embodiment is characterized in that the at least one plug contact element is designed such that, in the inserted state, not only a defined contact region with the plug contact carrier, in particular in the form of a stop and/or a bearing surface and/or a guide surface, but also a region is present in which an intermediate space is present between the components. Such an intermediate space can be realized, for example, by at least locally thinning the plug contact element. In the region of interest, for example in the region of the socket element and/or the pin element, at least one plug contact element is therefore not seated on the plug contact carrier. In particular, a defined contact region with the plug contact carrier is preferably arranged in the connection region of the plug contact element.
Such a design has the advantage that manufacturing-related tolerances in respect of the planarity of the plug contact element and/or the plug contact carrier have substantially no influence on the position of the plug contact element in the plug contact carrier.
According to a further embodiment, the plug contact element preferably has at least two bearing surfaces in the connection region, with which the plug contact element rests on the plug contact carrier. Preferably, the sum of the bearing surfaces is generally less than 50% or less than 40% or less than 30% of the possible bearing surfaces.
Particularly preferably, the plug contact element has exactly two bearing surfaces with which the plug contact element rests on the plug contact carrier. This design is an optimum compromise between ensuring a stable position of the plug contact element in the plug contact carrier on the one hand and ensuring sufficient free space between the components on the other hand in order to minimize the influence of tolerances caused by manufacturing.
Particularly preferably, the plug contact carrier has at least one stop face for positioning at least one plug contact element in the plug-in direction, wherein the plug contact element has at least one mating stop face, and wherein each mating stop face rests against the stop face of the plug contact carrier in the plugged-in state. A defined positioning of the plug contact element in the plugged-in state can be ensured by a defined number of stop faces, wherein the stop faces limit in particular a movement of the plug contact element in the plugging-in direction. According to a particularly preferred embodiment, the plug contact carrier has at least two stop faces, wherein the plug contact element in the inserted state rests with two counter-stop faces on the two stop faces. In this way, a particularly precise positioning of the plug contact element in the plug contact carrier can be ensured.
According to a particularly preferred embodiment, at least one plug contact element is produced from a flat metal material by means of stamping. The plug contact element produced in this way is advantageously distinguished from the stamped and bent contacts known from the prior art by a particularly simple production process. If a latching element is arranged on the plug contact element, it can be formed directly during the stamping process.
The plug contact carrier is preferably composed of plastic.
It is furthermore advantageous if the plug contact carrier has at least three guide elements, in particular guide elements in the form of guide surfaces, wherein the guide elements guide and/or stabilize at least one plug contact element in three spatial directions during and/or in the inserted state.
According to a particularly preferred embodiment, the plug contact carrier has at least one guide element, preferably in the form of a guide rail, wherein the guide element extends in the insertion direction, and wherein the plug contact element is inserted into the plug contact carrier along the guide element for connecting the component.
If the plug contact carrier has a plurality of plug contact elements, a guide element, preferably in the form of a guide rail, is arranged at the plug contact carrier, preferably for each plug contact element. It is also advantageous if the guide elements extend in the plug-in direction on both sides of the plug contact element, so that a straight insertion of the plug contact element into the plug contact carrier can be ensured.
According to a further embodiment, the guide element is designed as a guide housing, wherein the guide housing extends in the insertion direction on three sides of the plug contact element. This embodiment already ensures a particularly precise positioning of the plug contact element during insertion.
According to a particularly preferred embodiment, the guide housing has a recess into which the latching element of the plug contact element snaps in the inserted state. In this embodiment, the recess of the guide housing functions as a snap-fit counter element.
According to a second teaching of the invention, the object set forth at the outset is achieved by the plug contact element mentioned at the outset for connecting with a plug contact carrier, i.e. the plug contact element is designed to form a system according to the above-described embodiment. For this purpose, the plug contact element has the features of at least one of the above-described embodiments.
Furthermore, the plug contact element for connection to the plug contact carrier can also be designed according to one of the following embodiments.
According to a further advantageous embodiment, the plug contact element is produced by stamping and is worked after stamping in at least one contact region. The improvement of the surface quality and the cutting edges produced by the stamping process is achieved by plastic deformation. As a result, the electrical connection to the plug contact element can be improved.
In particular, the plug contact element is preferably embossed both in the region of the socket element and in the region of the pin element.
It is also advantageous if the socket element is at least partially tapered. This has the advantage that the contact opening dimensions can be calibrated simply and precisely in the region of the taper after stamping.
A further advantageous embodiment of the plug contact element is characterized in that the pin element is widened such that the pin element has a greater material thickness than the rest of the plug contact element. This has the advantage that the contact is made easier by the enlargement of the overlapping surfaces when the pin elements are joined. For example, the pin element may be widened by plastic deformation after stamping.
According to a third teaching of the invention, the object set forth at the outset is achieved by the plug contact carrier described at the outset for accommodating at least one plug contact element, i.e. the plug contact carrier is designed to form a system according to the preceding embodiments. For this purpose, the plug contact element has the features of at least one of the above-described embodiments.
According to a fourth teaching, the object set forth at the outset is achieved by a plug connector, in particular a direct plug connector for contacting a circuit board, preferably via a plug connection, comprising a system of a plug contact carrier and at least one plug contact element according to one of the above-described embodiments and furthermore comprising a housing.
Furthermore, the plug connector, in particular the direct plug connector, may alternatively or additionally be designed according to one of the following embodiments.
According to a preferred embodiment, the plug connector has a housing, wherein the housing has a receiving region for receiving the plug contact carrier, wherein the receiving region has at least two borders, preferably lateral borders, wherein the at least two borders of the receiving region are fixed in a connecting state in a connecting form-fitting and/or force-fitting manner. In particular, the boundary preferably extends in the insertion direction of the plug contact carrier, so that a fixation extending over the entire receiving region can be ensured. The boundary is configured, for example, as a boundary wall or a boundary edge. Particularly preferably, the at least two borders are configured as side walls lying opposite one another.
It is thereby ensured that the plug contact elements arranged in the plug contact carrier, which are provided for connection, can be particularly advantageously positioned in the housing by inserting the plug contact carrier into the receiving region of the housing and fixing the plug contact carrier in the inserted state by form-fitting and/or force-fitting the receiving region. In this way, a stable positioning of the plug contact element provided for the connection is likewise achieved.
According to a further advantageous embodiment, the receiving areas of the plug contact carrier and the housing are designed such that the plug contact carrier can be pushed into the receiving area and during the pushing-in there is firstly a clearance fit and in the fully inserted state the plug contact carrier is only fixed by at least one press fit.
Particularly preferably, the press fit is realized in the inserted state by a transition fit or an interference fit.
According to a further embodiment, the plug contact carrier is positioned and/or fixed in the plugged-in state by at least two press fits, wherein preferably one press fit is realized in a rear region of the plug contact carrier in the plugging direction, and wherein a second press fit is realized in a front region of the plug contact carrier in the plugging direction.
The press fit can preferably be achieved in that, in the unconnected state, the distance between the side walls or the side edges of the plug contact carrier is at least partially greater than the distance between the lateral boundaries of the receiving region.
According to a further advantageous embodiment, the lateral boundaries of the receiving region of the housing and/or the side walls or the side edges of the plug contact carrier are not oriented parallel to one another at least in some regions, but the distance between the lateral boundaries of the receiving region and/or the distance between the side walls or the side edges of the plug contact carrier decreases in the insertion direction of the plug contact carrier.
According to a further embodiment, the press fit can also be achieved or improved in that at least one lateral boundary of the receiving region is not parallel to the adjacent side wall or side edge of the plug contact carrier. The angle to the respective adjacent side wall or side edge lies in the range between 0.5 and 10 °, preferably between 0.5 and 5 °, particularly preferably between 0.5 and 2 °.
The press fit can also be achieved or improved in that at least one side wall or side edge of the plug contact carrier is not parallel to the adjacent lateral boundary formation of the receiving region. The angle to the respectively adjoining lateral boundary lies in the range between 0.5 and 10 °, preferably between 0.5 and 5 °, particularly preferably between 0.5 and 2 °.
Alternatively or additionally, the press fit can also be achieved in that at least one lateral boundary of the receiving region and/or at least one side wall or lateral edge of the plug contact carrier has at least one step.
According to a particularly preferred embodiment, in the connected state, one press fit is realized by two steps of the lateral boundary of the receiving region lying opposite one another, and the second press fit is realized by two steps of the side wall or the lateral edge of the plug contact carrier lying opposite one another.
A further embodiment of the plug connector is characterized in that the receiving region has at least three borders, such that the borders surround the plug contact carrier on at least three sides. In particular, the boundary is preferably arranged such that it limits the movement of the plug contact carrier not only laterally but also in the insertion direction and, in this respect, positions the inserted plug contact carrier in a form-fitting manner on at least three sides.
According to a further embodiment, the receiving region has at least four boundaries for positioning and fixing the plug contact carrier, which boundaries are arranged in such a way that the boundaries position and/or fix the plug contact carrier not only laterally but also in the insertion direction and opposite the connection to the circuit board.
Particularly preferably, the border is arranged as a base opposite the circuit board to be plugged in. The forces acting when the circuit board is plugged in can be absorbed by the base, as a result of which the plug contact element is relieved of load.
Furthermore, it is preferred that the housing has a lateral opening in the receiving region, wherein the lateral opening is oriented perpendicularly with respect to the plugging direction of the circuit boards to be connected.
In order to improve the fixing of the plug contact carrier in the housing, it is furthermore advantageous if the plug contact carrier preferably has at least one latching element, for example in the form of a latching nose or a latching hook, in the region of the side wall, wherein the at least one latching element in the inserted state latches into a latching counter-element, for example in the form of a recess, wherein the latching counter-element is preferably arranged in the region of a lateral boundary of the receiving region of the housing. In particular, it is preferred that at least one latching element is arranged and configured in such a way that it projects beyond a side wall or a side edge of the plug contact carrier. In particular, the latching element is elastically deflected and/or deformed during the insertion process, wherein the latching element snaps into its original shape and/or position into the latching counter-element.
For example, the latching counter-element can be designed as a recess in the lateral boundary of the receiving region, wherein the latching element snaps into the recess in the inserted state. Alternatively, the lateral boundaries of the receiving region may also have an abrupt or continuous change in the spacing of the boundaries.

Detailed Description
In fig. 1, a first embodiment of a system 1 according to the invention is represented in the unconnected state, which system comprises a plug contact carrier 2 and three plug contact elements 3.
The plug contact elements 3 each have a socket element 4, a pin element 5 and a plug element 6 with contact prongs for direct contact via corresponding contact holes of the circuit board 15. The region of the plug contact element 3 between the contact regions 4,5 and 6 is referred to as the connection region 14. The plug contact element 3 presented is produced by means of stamping.
The plug contact element 3 and the plug contact carrier 2 are designed such that the plug contact element 3 can be inserted into the plug contact carrier 2 for stable positioning.
In order to fix the plug contact elements 3 in the plug contact carriers, the plug contact elements 3 each have a latching element 7 which, in the inserted state, forms a latching connection with a corresponding latching counterpart element 8 at the plug contact carrier 2. The latching elements 7 are each arranged in a connecting region 14 of the plug contact element. This ensures that the latching connection, for example, without complete latching, has no effect on the contact region and, for this reason, on the quality of the contact.
Fig. 2 shows the embodiment presented in fig. 1 in a plugged-together state. In addition to the latching connection formed by latching elements 7 and counter-latching elements 8 for fixing the plug contact elements 3, the plug contact carrier also has a guide element 9 for each plug contact element 3, wherein the guide element 9 not only stabilizes the position of the plug element 6 but also ensures a straight insertion of the respective plug contact element 3.
The embodiment presented in fig. 2 is shown in a sectional view in fig. 3. In addition to the components already described, the illustration in fig. 3 shows that the plug contact element 3 has exactly two bearing surfaces 10 with which the plug contact element 3 rests on the plug contact carrier 2. In this way, as large a free space as possible between the components can be ensured, so that manufacturing-related tolerances have substantially no influence on the position of the plug contact element 3 in the plug contact carrier 2.
Furthermore, the plug contact carrier 2 has a stop face 11 for positioning or limiting the movement of the plug contact element 3 in the plug-in direction. In the inserted state, the plug contact element 3 rests with the counter-stop surface 12 against the stop surface 11.
As a result, the system 1 shown in fig. 1 to 3, which is formed by the plug contact element 3 inserted into the plug contact carrier 2, has the advantage that, on the one hand, the plug contact element 3 can be accommodated particularly easily by the plug contact carrier 2 and, at the same time, the precise positioning of the plug contact element 3 in the plug contact carrier 2 can be ensured, in particular, by a latching connection.
Fig. 4 shows an exemplary embodiment of a direct plug connector 13 having the system 1 shown in fig. 2, which is composed of a plug contact carrier 2 and plug contact elements 3 arranged in the plug contact carrier 2. The plug contact carrier 2 is arranged in a receiving region 16 of the housing, wherein the receiving region 16 fixes the plug contact carrier 2 by press-fitting form-fitting and force-fitting. Furthermore, a circuit board 15 is present, which can be connected to the direct plug connector 13.
