Description
Technical Field
The invention relates to a plug contact element for producing an electrical connection between two components, in particular between a component and a printed circuit board, wherein the plug contact element is produced by stamping.
The invention further relates to a direct plug connector comprising at least one plug contact carrier, wherein at least one plug contact element according to the invention is arranged in the plug contact carrier and has a housing, wherein the at least one plug contact carrier is arranged in the housing.
The invention further relates to a method for producing a plug contact element and to a method for producing a direct plug connector.
Background
Stamped contact metals are known from the prior art.
The printed document DE 10249683B 4 discloses a contact element for electrically contacting a mating contact, having a contact section with two spring-elastic clamping arms for contacting the mating contact and having a base section for connection to a circuit board. The contact element is here, according to one embodiment, a sheet metal stamping.
Furthermore, a plug contact for connecting a conductor to a circuit board by means of direct plug technology with a mounting frame is known from the printed document DE 202016105358U 1, wherein the plug contact is designed as a stamped bent part.
Disclosure of Invention
Starting from the prior art described, the object of the present invention is to provide a plug contact element which is particularly simple to produce and whose functionality is improved. The object of the invention is also to provide a direct plug connector comprising at least one contact element according to the invention.
According to a first teaching of the invention, the aforementioned object is achieved by the plug contact element mentioned at the outset in that the plug contact element has at least one pin element and/or at least one socket element for connecting to a component to be connected, and at least one plug element for directly contacting a circuit board.
According to the invention, it is known that contact elements suitable for direct plug technology can be designed as pure stampings, so that complex bending steps can be avoided.
According to a further preferred embodiment, the plug contact element is reworked in at least one contact region by embossing (Pr ä gen). By means of the plastic deformation, an improvement of the surface quality and of the cut edges occurring by the punching process is achieved. In particular, the plug contact elements are preferably stamped both in the region of the socket element and in the region of the pin element, so that as a result an electrical connection to the plug contact elements can be improved.
According to one advantageous embodiment, the socket element is at least partially tapered. This has the advantage that a simple and precise calibration of the degree of contact opening can be achieved after punching in the tapered region.
A further advantageous embodiment of the plug contact element is distinguished by the fact that the pin element is at least partially expanded in such a way that it is wider than the material thickness of the remaining part of the plug contact element. This has the advantage that contact is more easily made when joining the pin element into the socket element due to the increased overlap surface. For example, the pin element may be expanded after punching by plastic deformation.
The plug contact element according to the invention is suitable for being accommodated in a plug contact carrier.
The system of the plug contact carrier and the at least one plug contact element can be designed within the scope of the invention, also according to one or more of the following embodiments.
According to a further advantageous embodiment, the plug contact elements have a connecting region, which connects the contact regions to one another. Advantageously, 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 connecting 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 particularly simple 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 after insertion by a latching connection. Since the latching connection is in the connection region of the plug contact element and is therefore not arranged 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 deteriorated contact quality.
As a result, the system therefore ensures a particularly simple connection of the at least one plug contact element to the plug contact carrier on the one hand and an improved contact with further components on the other hand.
For example, the latching connection is designed as a rear latch. 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 at 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 lug or a latching hook, and the plug contact carrier has a latching counterpart element, in particular in the form of a recess, wherein the latching element, in the inserted state of the plug contact element, forms a latching connection with the latching counterpart 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 lugs or latching hooks, which in the inserted state snap into latching counter-elements, in particular in the form of recesses, arranged on the 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 assumes an original shape or position, whereby a form-and/or force-fitting latching connection is achieved.
According to a further preferred embodiment, the 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 between the at least one plug contact element and the plug contact carrier is optionally present, in particular in the form of a stop and/or a resting surface and/or a guide surface, wherein the defined contact region stabilizes the position of the plug contact element in the plug contact carrier.
A further advantageous embodiment is distinguished by the fact 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 resting face and/or a guide face, but also a region is present in which an intermediate space between the components is present. Such an intermediate space can be realized, for example, by an at least partial thinning of the plug contact element. In a basic region, such as, for example, in the region of the socket element and/or the pin element, the at least one plug contact element is therefore not arranged on the plug contact carrier. Particularly preferably, the defined contact region is arranged in the connection region of the plug contact element together with the plug contact carrier.
Such a design has the advantage that manufacturing-related tolerances with regard to the flatness of the plug contact element and/or the plug contact carrier have no influence on the position of the plug contact element in the plug contact carrier.
According to a further embodiment, the plug contact element has at least two contact surfaces, preferably in the connecting region, with which the plug contact element is arranged on the plug contact carrier. Preferably, the total number of seating surfaces is less than 50% or less than 40% or less than 30% of the possible seating surfaces in total.
Particularly preferably, the plug contact element has exactly two contact 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 effect of manufacturing-induced tolerances.
In particular, the plug contact carrier has at least one stop surface for positioning the at least one plug contact element in the insertion direction, wherein the plug contact element has at least one mating stop surface and wherein each mating stop surface in the inserted state rests against the stop surface of the plug contact carrier. The defined positioning of the plug contact element in the inserted 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 insertion direction. According to a particularly preferred embodiment, the plug contact carrier has at least two stop surfaces, wherein the plug contact element in the inserted state rests with two mating stop surfaces against the two stop surfaces. 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, the at least one plug contact element is produced from a metallic flat material by means of stamping. The plug contact element produced in this way is distinguished by a particularly simple production process from the stamped bent-out contact known from the prior art in an advantageous manner. If a latching element is arranged on the plug contact element, it can be deformed directly during the punching operation.
The plug contact carrier is preferably made of plastic.
Furthermore, it is 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 the 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 track, is arranged at the plug contact carrier, preferably for each plug contact element. Furthermore, the guide elements advantageously extend in the insertion direction at both sides of the plug contact element, so that a straight introduction 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 accurate 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.
According to a second teaching of the present invention, the object set forth at the outset is achieved by a direct plug connector comprising at least one plug contact carrier, wherein at least one plug contact element according to one of the embodiments described above is arranged in the plug contact carrier and has a housing, wherein the at least one plug contact carrier is arranged in the housing.
Furthermore, the direct plug connector can alternatively or additionally be designed according to one of the following embodiments.
According to a preferred embodiment, the direct plug connector has a housing, wherein the housing has a receiving region, wherein the receiving region has at least two, preferably laterally directed, limits, wherein the at least two limits of the receiving region positively and/or non-positively fix the plug contact carrier. Particularly preferably, the limiting section extends in the insertion direction of the plug contact carrier, so that a fixing extending over the entire receiving region can be ensured. For example, the limiting section is configured as a limiting wall or a limiting edge. Particularly preferably, the at least two limiting portions are configured as side walls lying opposite one another.
In this way, it can be ensured that the plug contact element arranged in the plug contact carrier and provided for connection can be positioned in the housing particularly advantageously 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 elements provided for joining 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 the 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 inserted state by at least two press fits, wherein preferably the press fit is realized in a region of the plug contact carrier behind in the insertion direction and wherein the second press fit is realized in a region of the plug contact carrier ahead in the insertion direction.
The press fit can preferably be achieved in that, in the unconnected state, the distance of the side walls or side edges of the plug contacting the carrier is at least partially greater than the distance of the lateral limiting sections of the receiving region.
According to a further advantageous embodiment, the lateral limits of the receiving region of the housing and/or the side walls or side edges of the plug contact carrier are oriented at least partially non-parallel to one another, but the distance between the lateral limits of the receiving region and/or the distance between the side walls or side edges of the plug contact carrier decreases in the insertion direction of the plug contact carrier.
The press fit can also be achieved or improved according to a further embodiment in that at least one lateral limitation of the receiving region is not parallel to the adjacent side wall or side edge of the plug contact carrier. The angle to the respectively adjacent side wall or side edge is preferably in the range of 0.5 and 10 °, preferably in the range of 0.5 and 5 °, particularly preferably in the range of 0.5 and 2 °.
The press fit can also be achieved or improved by at least one side wall or side edge of the plug contact carrier not being parallel to the adjacent, laterally directed limiting formation of the receiving region. The angle to the respectively adjacent lateral limitation is preferably 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 limitation 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, the press-fitting in the connected state is effected by two mutually opposite step portions of the lateral limiting section of the receiving region, and the second press-fitting is effected by two mutually opposite step portions of the side wall or the lateral edge of the plug contact carrier.
The next embodiment of the direct plug connector is distinguished by the fact that the receiving region has at least three restrictions, so that the restrictions surround the plug contact carrier on at least three sides. In particular, the limiting section is preferably arranged such that it limits the movement of the plug contact carrier not only laterally but also in the insertion direction and, for this purpose, positively locates the inserted plug contact carrier at least three sides.
According to a further embodiment, the receiving region has at least four limiting portions for positioning and fixing the plug contact carrier, which are arranged in such a way that they position and/or fix the plug contact carrier both laterally and in the insertion direction and opposite the connection of the circuit board.
Particularly preferably, the limiting section is arranged as a base opposite the circuit board to be plugged in. The forces acting during the insertion of the circuit board can be absorbed by the base, as a result of which the plug contact element is relieved.
It is furthermore preferred that the housing has a lateral opening in the receiving region, wherein the lateral opening is oriented substantially perpendicularly with respect to the plug direction of the circuit board to be connected.
In order to improve the fastening of the plug contact carrier in the housing, it is furthermore advantageous if the plug contact carrier, preferably in the region of the side wall, has at least one latching element, for example in the form of a latching lug or latching hook, 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 limitation of the receiving region of the housing. In particular, the at least one latching element is preferably arranged and designed in such a way that it projects beyond the side wall or the 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 the latching counter-element in its original shape and/or position.
For example, the latching counter-element can be designed as a recess in a lateral limitation of the receiving region, wherein the latching element snaps into the recess in the inserted state. Alternatively, the lateral limitation of the receiving region can also have a sudden or continuous change in the distance of the limitation.
The object set forth at the outset is achieved according to the further teaching by a method for producing the plug contact element described above in that the plug contact element is produced by punching.
Optionally, the contact area of the plug contact element is embossed after the punching of the plug contact element for improving the quality of the surface and/or the cut edge.
According to a further advantageous embodiment, the plug contact element tapers at least partially in the region of the socket element, particularly preferably in a front portion of the socket element. The tapering may already be achieved during the punching process or as such be introduced afterwards. The subsequent setting of the degree of contact opening by plastic deformation can be achieved particularly simply, in particular in the region of the taper.
In this connection, a further embodiment of the method is distinguished in that the contact opening degree of the socket element is calibrated by plastic deformation after punching, in particular in the tapered region.
In particular, it is preferred that the contact region of the socket element and/or the pin element is first of all realized to be wider during the stamping, so that a plastic deformation of this region is possible at the desired gauge with an improved surface quality.
In order to improve the quality of the cut-off edge, the cut-off edge in the contact region is flattened at least in some regions after the punching according to a further embodiment.
Particularly preferably, the pin element is expanded at least in regions by plastic deformation, so that the contact build-up is improved with the pin element by a particularly wide surface available for use. The pin element is preferably expanded such that the set width is greater than the material thickness of the remaining plug contact elements.
