Description

Plug connector, plug contact carrier, housing and method for producing a plug connector
Technical Field
The invention relates to a plug connector, in particular a direct plug connector, for electrically connecting two components, in particular for connecting a component to a circuit board, comprising a housing and at least one plug contact carrier, wherein the plug contact carrier has at least one plug contact element, and wherein the plug contact carrier is arranged in the housing in the connected state. The invention further relates to a plug contact carrier for accommodating at least one plug contact element for use in a plug connector according to the invention, to a housing for use in a plug connector according to the invention, and to a method for producing a plug connector.
Background
Plug connectors for establishing electrical contact between, in particular, individual components and a circuit board are known from the prior art. For example, DE 202016105358U 1 discloses a plug contact for connecting a conductor to a circuit board, wherein the plug contact can be inserted into a plug contact carrier, and wherein the plug contact is positioned in the contact carrier via a mounting frame and via a latching connection.
Furthermore, a plug connector with a housing is known from the publication DE 102013111571B 4.
Disclosure of Invention
Starting from the prior art described, the object of the invention is to specify a plug connector in which the positioning of the plug contact elements and the accommodation of the plug contact carrier with the plug contact elements in the housing are improved.
According to a first teaching of the present invention, the above object is achieved by a plug connector having the features of patent claim 1 in that the housing has a receiving region, wherein the receiving region has at least two borders, preferably lateral borders, wherein the at least two borders of the receiving region fix the plug contact carrier in the connected state in a 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.
According to the invention, it is recognized that plug contact elements arranged in the plug contact carrier and provided for connection can be positioned particularly advantageously in the housing in such a way that the plug contact carrier is inserted into the receiving region of the housing and, in the inserted state, is positively and/or non-positively fixed by the receiving region. In this way, a stable positioning of the plug contact element provided for the connection is likewise achieved.
According to an 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 is preferably 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 side 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 mutually opposite step portions of the lateral boundary of the receiving region, and the second press fit is realized by two mutually opposite step portions of the side walls or the lateral edges of the plug contact carrier.
A further embodiment of the plug connector is characterized in that the receiving region has at least three boundaries, such that the boundaries 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 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 substantially 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 or the lateral edge, 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 the lateral boundary of the receiving region of the housing. In particular, it is preferred that at least one latching element is arranged and designed in such a way that it projects as a projection beyond the side wall or the lateral 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 the latching counter-element in its original shape and/or position in the inserted state.
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.
The system of plug contact carrier and at least one plug contact element may alternatively or additionally also be designed according to one or more of the following embodiments within the scope of the invention.
According to a further advantageous embodiment, the at least one plug contact element has at least one socket element (Buchsenelement) and/or at least one pin element and/or at least one plug element for directly contacting the circuit board and a connection region, wherein the connection region connects the contact regions to one another. Advantageously, 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 this embodiment, the 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 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 latching connection is designed as a rear latch (hinderastung). 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 region, 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 region 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 partially 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. Particularly preferably, a defined contact region with the plug contact carrier is 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 plugged-in state rests with two counter stop faces against 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.
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 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, for connecting the component, the plug contact element is inserted into the plug contact carrier along the guide element.
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 insertion 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 acts as a snap-fit counter element.
In addition to the above-described embodiments, the at least one plug contact element can also have one or more of the following features.
According to one 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. 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, so that as a result an improved electrical connection to the plug contact element is possible.
According to one advantageous embodiment, 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 second teaching of the invention, the object set forth at the outset is achieved by the plug contact carrier described at the outset for use in a direct plug connector having at least one plug contact, i.e. having the features according to one of the above-described embodiments of the plug connector.
According to a third teaching of the present invention, the object set forth at the outset is achieved by the initially described housing for use in a direct plug connector, i.e. having the features according to one of the above-described direct plug connectors.
The invention further relates to a method for producing a direct plug connector having a housing and a plug contact carrier, wherein the housing has a receiving region for the plug contact carrier, comprising the following method steps:
Inserting at least one plug contact element into the plug contact carrier, wherein preferably the at least one plug contact element is positively and/or non-positively fixed in its position by a snap connection directly after insertion,
the plug contact carrier with the at least one plug contact element is inserted into the receiving region of the housing, wherein the plug contact carrier is fixed in its position directly after insertion in a form-fitting and/or force-fitting manner.
Preferably, the method is suitable for producing the direct plug connector described above.

Detailed Description
Fig. 1 shows a first exemplary embodiment of a plug contact carrier 2 with three plug contact elements 3 in the unconnected state. 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 connection and positioning, and the plug contact element 3 is positioned and fixed in the plug contact carrier 2 by means of a latching connection. For this purpose, each plug contact element 3 has a latching element 10 which, in the connected state, latches into a latching counterpart element 11 arranged on the plug contact carrier 2. Thus, complicated methods for pre-positioning and for connecting the plug contact element 3 with the plug contact carrier 2 can be avoided.
The plug contact carrier 2 is furthermore designed such that it can be inserted into the receiving region 4 of the housing 17.
Fig. 2 shows the plug contact carrier 2 presented in fig. 1 and the plug contact element 3 in the inserted state. Furthermore, the receiving region 4 of the housing 17 of the direct plug connector 1 is represented. The receiving region 4 has lateral boundaries 5 in the form of side walls extending in the insertion direction, which boundaries locate the plug contact carrier 2 and guide or limit the insertion movement. Furthermore, the plug contact carrier 2 and the receiving region 4 are designed such that the plug contact carrier 2 is only positively and/or non-positively fixed in the fully inserted state. During the insertion process, there is therefore a clearance fit, so that the plug contact carrier 2 can be moved in the insertion direction.
In addition, the side walls or lateral edges 6 of the plug contact carrier 2 each have a latching element 7, which in the inserted state engages into a latching counter-element (here in the form of a recess 9) in the lateral boundary 5 of the receiving region 4. The plug contact carrier 2 is fixed in its position by the detent connection formed in this way, and in particular the plug contact carrier 2 is prevented from sliding out of the housing 17.
Fig. 3 shows the system represented in fig. 2, which is composed of the plug contact carrier 2 and the receiving region 4 of the housing in the plugged-in state. By fixing the plug contact carrier 2 in the receiving region 4, the plug contact element 3 is likewise fixed in its position, so that a particularly advantageous connection to the circuit board 8 can be made. For contacting the circuit board 8, the plug contact element 3 has a plug element which is designed in such a way that it ensures the connection by insertion into a corresponding contact hole in the circuit board 8. Furthermore, the receiving region 4 of the housing 17 has a base 14 which, when the direct plug connector is connected to the circuit board 8, absorbs forces acting on the plug contact elements 3 and thus relieves the load on the plug contact elements 3.
Fig. 4 shows the plug contact carrier 2 inserted into the housing 17 and the receiving region 4 of the housing 17 in a sectional view. For fixing in the receiving region 4, the plug contact carrier 2 has latching elements 7, which in the inserted state assumed snap into recesses 9 of the lateral boundary 5 of the receiving region 4.
The side walls or lateral edges 6 of the plug contact carrier 2 and the lateral boundaries 5 of the receiving region 4 are designed in the exemplary embodiment shown such that at the beginning of the insertion process there is a clearance fit (which effects the insertion of the plug contact carrier 2) and only at the end of the insertion does the plug contact carrier 2 be fixed by press fitting. For this purpose, there is an interference fit both in the front region in the insertion direction and in the rear region in the insertion direction, which interference fit is represented in an enlarged view in fig. 5a and 5 b.
Fig. 5a shows an interference fit 13 in the front portion a of the plug contact carrier 2 in the insertion direction. In order to produce the interference fit 13, the lateral boundaries 5 of the receiving region 4 have a step 12, so that in the region of the interference fit 13 the distance between the lateral boundaries 5 of the receiving region 4 is smaller than the distance between the side walls or side edges 6 of the plug contact carrier 2.
Fig. 5B shows an interference fit 13 in the rear section B of the plug contact carrier 2 in the insertion direction, in which region the side walls 6 of the plug contact carrier 2 have steps 12 in order to realize the interference fit 13, whereby the spacing of the side walls 6 of the plug contact carrier 2 in the region of the interference fit 13 is greater than the spacing of the lateral boundaries 5 of the receiving region 4. Furthermore, the side walls 6 of the plug contact carrier 2 are angled with respect to the lateral boundaries 5 of the receiving region 4, as a result of which entry ramps are produced in the insertion direction, which facilitate the insertion of the plug contact carrier 2.
Fig. 6 shows a method for producing a direct plug connector, the direct plug connector 1 being configured as shown in fig. 3. The method comprises the following steps:
inserting 15 at least one plug contact element 3 into the plug contact carrier 2, wherein the at least one plug contact element 3 is positively and/or non-positively fixed in its position by a snap-on connection directly after insertion, and
inserting 16 the plug contact carrier 2 with the at least one plug contact element 3 into the receiving region 4 of the housing, wherein the plug contact carrier 2 is positively and/or non-positively fixed in its position directly after the insertion.
