Definitions
- the invention relates to a contact element, designed as a one-piece stamped and bent part, with a latching element for fixing the contact element in a contact chamber of a connector, further comprising a first contact spring, which extends at least partially in a receiving region of the contact element for contacting with an inserted into the receiving area mating contact, according to the features of the preamble of claim 1.
- Such a generic contact element is known from EP 2 193 577 B1.
- a sheet-metal part stamped out flat with the required contours is used.
- the preparation based on such a flat structure in a stamping bending process has the advantage that the desired geometries of the contact element for the realization of its later function in the connector very simple and, above all, rational, that is inexpensive in large quantities, allow.
- an electrical conductor for example, a stamped grid, a cable or the like
- Such a locking element is therefore necessary, as well as a contact spring, which is provided in a receiving region of the contact element.
- a mating contact is introduced and thus brought this mating contact of a mating connector with the associated contact element of the connector in operative connection.
- Such connectors consisting of connectors and cooperating mating connector, are in practice very high stresses, especially in the automotive sector exposed. These stresses are primarily moisture, dirt, vibration and temperature differences. These impairments often lead to difficulties in the electrical contact with the contact area, so that the required signal transmission, energy transmission or the like is impaired or no longer guaranteed via the plug connection. In the worst case, these contacts can completely eliminate electrical contact with the contacts.
- the invention is therefore based on the object to improve a known contact element to the effect that ensures a stable and secure contact over a very long period of time and is ration part manufacturable in large quantities.
- a contact spring opposite a second contact spring is associated, which is also formed by the stamped and bent part.
- the contact spring is advantageously increased by the second contact spring, since in the case that problems should arise in the contact region between the first contact spring and the contact element lying thereon, the second contact spring is still connected to the mating contact which has been inserted into the receiving region. is applied.
- the contact reliability especially with regard to the entire life of the connector, significantly increased.
- such a contact element with two contact springs can be produced in a rational manner, that is, in large numbers, very simply by virtue of the fact that the second contact spring is likewise formed by the stamped and bent part, that is to say the flat component in the initial state.
- the contours of the second contact spring and the connection to the base material can be easily realized by a punching process. If this is done, in a known manner the flat part bent in the required manner in the desired dimensions until the finished contact element is available.
- the contact element is formed in a particularly advantageous manner completely as a one-piece stamped bent part, without further parts for the realization of the contact element (apart from the electrical conductor) exist.
- it can be thought of to carry out individual parts as separate components and to form-fit and / or cohesively to the one-piece stamped and bent part.
- this is not the basic concept of the one-piece stamped and bent parts are given up, that is, that in the components to be attached are only the smallest components.
- the second contact spring is at least with its one end of the stamped and bent part.
- the preferably elongated second contact spring is arranged with its one end on the stamped bent part, that is, the main body of the contact element, and protrudes into the receiving area for the mating contact in that the second contact spring is deflected when the mating contact is introduced into the receiving area , whereby a spring force acts on the mating contact.
- the second contact spring is deflected about the point at which it is arranged with its one end on the stamped and bent part. In this case, the free end can move on a circular path and be deflected in the desired manner to allow insertion of the mating contact in the receiving area.
- the second contact spring extends with its two ends of the stamped and bent part.
- the preferably again elongated second contact spring has no free end, but the two ends of the main body of the contact element, namely the stamped and bent part, is fixed.
- the second contact spring for example, extends through an arc shape between the two ends, a Weileform or the like at least partially into the receiving area for the mating contact.
- the second contact spring with its two ends on the base body (Punch bending part) of the Kunststoffiementes is arranged, slightly after and comes to rest on the introduced counter contact, thereby applying a contact force is applied to the mating contact.
- the second contact spring emanates with its two ends of the stamped and bent part
- the second contact spring emanates with its at least one, preferably with its two ends, via a transverse web of the stamped and bent part.
- Such a crosspiece which is also formed on the one hand also by the stamped and bent part, but on the other hand in its axial course spaced from the main body (stamped and bent part), has the advantage that moving the second contact spring in the axial direction and / or transversely this can be achieved both during insertion of the mating contact into the receiving area and thereafter.
- This movement takes place for example in the micrometer range and has the advantage that movements of the counter contact are cushioned over the at least one transverse web, that the second contact spring is constantly applied to the mating contact, so advantageously a relative movement between the mating contact and the second contact spring to prevent.
- the latching element has a stop element cooperating with the stamped and bent part.
- the locking element stop element ensures that the locking element initially in the required manner of the stamped and bent part, that is, the main body of the contact element protrudes to come in a recess in the contact chamber of the connector to the plant when it is used there. This means that the locking element in the direction of the main body of the contact element is deflected so that the contact element can be inserted into the contact chamber. If it is in its desired position, the locking element, which was initially slightly compressed, springs back into the associated recess in the contact chamber to realize the primary locking.
- a stop element on the locking element is advantageously provided, which limits the path of the locking element in the direction of the stamped and bent part.
- the stop element of the locking element may be a separate component which is positively and / or cohesively arranged on the latching element. In a particularly advantageous manner, the stop element is already produced with punching of the locking element for the realization of the planar output part of the contact element.
- the stop element acts together via a stop with the stamped and bent part.
- the stop is also advantageously formed by the stamped and bent part, but may also be a separate separate form and / or material to be arranged separate component.
- the directional limit for the stop element can be adjusted in a defined manner.
- a free end of the first contact spring cooperates with a stop of the stamped and bent part, preferably the aforementioned stop.
- the movement of the first contact spring when inserting the mating contact is limited in the receiving area of the contact element.
- the contact element in its axial course of the receiving area on at least one projection for the mating contact.
- the at least one projection is provided in front of and / or behind the contact springs in the receiving region.
- defined contact surfaces of the mating contact in the receiving region of the contact element can thereby be targeted to adjust.
- Such projections are particularly advantageous both before and behind the contact springs.
- these projections are provided on all four opposite surfaces of the receiving area in front of and / or behind the contact springs.
- the at least one projection is formed as an embossment by the stamped and bent part.
- the receiving area and / or a hollow chamber extending parallel to the receiving area from the stamped and bent part is closed at the end.
- the front side of the area is defined in which the mating contact is used.
- the opening of the Hohihunt is closed at the front. This can take place in that the closure takes place through a region of the stamped and bent part itself. It can also the inlet opening of the Hohihunt the front side by a separate component form and / or materially closed.
- a closure of the frontal opening of the hollow chamber is possible in such a way that the contact chamber or the housing of the connector is inserted into the contact element is designed so that closed by the insertion of the contact element into the contact chamber of the frontal region of the hollow chamber becomes.
- the first embodiment is shown in Figures 1 to 9 and the second embodiment in Figures 10 to 14.
- the contact element is provided with the reference numeral 1.
- the starting point is a flat stamped and bent part 2, which has been punched in the desired contours from a suitable sheet-like and electrically conductive material (FIG. 1).
- Figures 2 to 9 show representations of the contact element 1 after the punching bending process has been carried out, that is, after the sheet-like stamped and bent part 2 shown in Figure 1 has been brought into the desired three-dimensional shape.
- FIGS. 2 to 4 show, in various three-dimensional views, the contact element 1, which has crimp blades 3 and strain relief wings 4 in a manner known per se for arrangement on an electrical conductor of a cable (not shown). These wings 3, 4 are present in a preferred manner, since with them a fast and efficient arrangement of the contact element 1 is given to the electrical conductor and thus to the cable.
- Alternative embodiments for the arrangement of the contact element 1 at the end the electrical conductor of the cable are therefore also conceivable, so that Crimperiel 3 and Switzerlandentlastungsfiügel 4 need not necessarily be present, but can be replaced by other elements.
- the finished contact element 1 has a contact region 5 in the front region of its elongated extension, a detent element 6 being present there.
- This locking element 6 is formed by the stamped and bent part 2 and is resiliently arranged at a deflection point on this. If the contact element 1 is inserted into a contact chamber of the connector, not shown here, the latching element 6 is deflected downwards as viewed in FIG. 2, so that all three surfaces 01, 02 and O3 are in one plane. After the contact element 1 has reached its final position in the contact chamber, it is possible due to a corresponding recess in the contact chamber, that the contact element 6 deflects again, so that the surfaces 01 and 02 are still aligned, but no longer the surface 03rd ,
- the contact element 1 has a first contact spring 7, likewise formed by the stamped and bent part.
- FIG. 3 it can be seen that a receiving area 8 is present, in which an unillustrated mating contact is introduced.
- a hollow chamber 9 is formed by the stamped and bent part 2. Those areas that form the hollow chamber 9 are required in order to arrange the locking element 6 here.
- a second contact spring 10 is provided, which is arranged opposite to the first contact spring 7.
- a stop 11 is present, this stop 11 is either formed by the stamped and bent part 2 itself or is a separate component which is added to the stamped and bent part 2 subsequently.
- the stopper 1 cooperates with a stop element 12.
- the stop element 12 is a component of the latching element 6 and is also formed by the stamped bent part 2 either in the stamping bending process or is a separate component which is connected to the latching element 6 is added later.
- the stop element 12 is arranged in an advantageous manner at the free end of the locking element 6 and may optionally extend beyond the free end of the locking element 6 addition.
- the stop element 12 and the associated region of the stamped and bent parts 2 are designed such that only the smallest possible clearance between the free end of the latching element 6 and the stop element 12 and the adjacent fixed areas of the stamped and bent part.
- penetration of foreign bodies is prevented in an advantageous manner (such as a cable, which is already struck in the field of Crimpulatel 3 and could penetrate into this area before the contact element 1 has been inserted into its associated contact chamber).
- opposite projections 13 are present in each case in the receiving region 8 in front of the contact springs 7, 10.
- these projections 13 may also be provided behind the contact springs 7, 10 (that is to say below the region designated by 02, see FIG. 2).
- FIG. 5 is again particularly well seen how the stopper 11 cooperates with the stop element 12 of the locking element.
- the latching element 6 protrudes from the contact element 1 in a defined manner.
- the outwardly facing surface O3 of the locking element 6 is not in a plane with the two axially surrounding surfaces O1 and 02.
- the stop element 12 is located at the level of the surface 02 in order to check that the locking element 6 in the desired position the insertion of the contact element 1 is in the contact chamber. If the contact element 1 in the contact chamber used, the locking element 6 is deflected in the direction of the underlying receiving area 8 so far that the three surfaces 01 to 03 are in a plane.
- FIG. 7 shows a section AA in the end region of the contact element 1.
- the projections 13 are very well visible, which protrude into the receiving area 8 and allow targeted guidance of the mating contact used there. Only the sake of completeness, the lying behind this cutting plane further elements such as Crimpinatel 3, strain relief wings 4 and locking element 6 are indicated.
- FIG. 8 shows a section B-B through the contact element 1 according to FIG. 5.
- a further projection 13 can be seen very well in the receiving region 8, which in turn is introduced as an embossing in the stamped and bent part 2.
- the stop 1 is shown, which is also formed by the stamped and bent part 2.
- FIG. 9 shows a section CC through the contact element 1 according to FIG. 6.
- the hollow chamber 9 extends parallel to the receiving region 8 for the mating contact.
- the locking element 6 with its stop element 12 can be seen, which cooperates with the stop 11 (preferably formed by the stamped bent part 2), in this illustration can also be seen that a free end 14 of the first contact spring 7 also with a stop, here with the Stop 11 cooperates.
- a targeted contact force can be set by the first contact spring 7 on the mating contact introduced into the receiving region 8.
- the stop 11 forms a travel limit both for the Anschiagelement 12 of the locking element 6 and for the free end 14 of the first contact spring 7. This makes a particularly compact design possible.
- both for the Ansch! Agelement 12 as well as for the free end 14 to provide two separate stops.
- FIG. 1 Another very important detail of the contact element 1 according to the invention can be seen in FIG. This is because the second contact spring 10 is connected via a respective transverse web 15 end to the stamped and bent part 2.
- This crossbar 15 is also very well visible in Figures 4 and 5. It is important that at least one end of the second contact spring 10, preferably (as shown in the figurative representations of the embodiment) both ends of the second contact spring 10 via such a cross bar 15 on the main body of the contact element 1, which is realized by the stamped and bent part, are arranged ,
- This connection of the second contact spring 10 via the at least one transverse web 15, preferably in each case a transverse web 5 at the free end of the contact spring 10, has the advantage that both axial movements of the contact spring 10 and movements transverse thereto are possible.
- the cross-sectional shape of the two contact springs 7, 10 is wave-shaped such that two protuberances protrude in the direction of the receiving region 8, which form the contact region for the mating contact. This makes it possible to define a defined contact region and, associated therewith, defined contact resistances.
- the contact spring 7, 10 should be designed in their cross-section in their longitudinal course so that defined contact areas are realized and a large-scale contact with the mating contact is avoided. Therefore, the wave-shaped course of the two contact springs 7, 10 shown in cross-section in FIG. 9 is of particular advantage.
- the contact spring 7 or 10 could thus also have a triangular, rectangular or comparable course or other courses.
- FIGS. 10 to 19 a further exemplary embodiment is shown analogously to FIGS. 1 to 9.
- the second embodiment differs from the first embodiment. in that the stop element 12 of the latching element 6 does not project beyond the end face (that is, the free end) of the latching element 6, but that it terminates flush with the end face and is curved in the direction of the stop 11 (FIG. 11).
- the free element of the Rasteiementes 6 as close to the adjacent part of the body (stamped bent part 2) are introduced, so that adjusts the smallest possible gap between these two components to there penetration of foreign bodies (such as Kabein or the like) prevent.
- FIGS. 10 to 19 wherein these important advantages of these details also apply to the contact element of the first exemplary embodiment according to FIGS. 1 to 9.
- FIG. 10 shows an anchoring 16 with which the region of the stamped and bent part 2 which forms the receiving region 8 is anchored.
- the area surrounding the receiving area 8 can also be referred to as a contact box, wherein the at least one anchoring, preferably the two anchors 16 shown, increase the stability and preferably engage in such a recess in the stamped and bent part 2, in which the area of the stamped and bent part, which forms the receiving area 8, merges into that area which forms the hollow chamber 9, which is designed as a box 17.
- a self-contained component namely the contact element 1
- the contact element 1 can be particularly easy to insert into the contact chamber of the connector.
- the cross-sectional shape of the box 7 ie, that portion of the stamped bent part 2, which surrounds the hollow chamber 9) to be particularly designed to allow a coding.
- the cross-sectional shape of the box 17 must correspond to the cross-sectional shape of the contact chamber of the connector, so that the contact element 1 can be used at all in this contact chamber of the connector.
- An encoding over the area surrounding the receiving area 8 is not possible since this contact area 5 is standardized with the receiving area 8 for the mating contact and thus does not permit coding.
- the box 17 has the particular advantage that with it a coding can be realized due to its design.
- the box 17 is also formed from the stamped and bent part 2, it has a material end 18 (for example in the form of a longitudinal edge) which can be supported on the corresponding area of the box around the receiving area 8. This effectively increases the stability. It can be thought of attaching the material end 18 positively and / or cohesively to the adjacent region of the stamped and bent part 2. Here comes, for example, a spot weld, a catch or the like into consideration. This determination can be made in the same manner as the anchor 16.
- the stopper 1 is designed as a curved tab which forms a Aufiage Structure, wherein the stop 11, in particular the curved tab, as a bearing surface for the adjacent Rasteiement 6 (when viewing the figure 10 above the stop 11) and / or the underlying contact spring 7 is used.
- this stop 11 serves as Studentsdehnstoff the contact latches in the form of primary locking mitteis the locking element. 6
- FIG. 11 shows that the stop element 12 of the stop 11 is arc-shaped.
- the latching element 6 has a recess 20 on the opposite side of the stop element 12.
- a material or consolidation compensation is created.
- an edge of the receiving area 8 is designated, wherein at this edge the stop element 11, in particular the bent tab comes after the stamping bending process to the plant.
- the lower edge of the material end 18 of the box 7 as shown in Figure 11 (left) partially supported plan-parallel on the edge 21.
- the material end 18 of the box 17 rests against a bent region of the stamped and bent part which forms the receiving region 8.
- the respective material end 18 of the box 17 may, but need not, be positively and / or materially joined to the adjacent area.
- FIG. 19 There is recognizable on the one hand, that the box 17, which forms the hollow chamber 9, is closed.
- a closure 22 in the form of a bent tab of the front part of the box 17 is formed.
- This closure 22 in the form of a bent tab can, but need not, engage in an end-side recess of the receiving area 8.
- the lower end side of the closure 22 can also be supported on the upper side of the receiving area 8, so that it does not have to have a recess.
- the locking element 6 optionally has a hook 23 which can correspond to a recess 24 in the rear box 17.
- this hook 23 can be designed in such a way that, when the surfaces 01-03 form a continuous plane, it comes into abutment against a part of the recess 24 in order to additionally or alternatively to the stop element 12 provide overstretch protection of the detent element 6 to effect.
- the stop element 12 regardless of which geometry
- the hooks 23 define a travel limit of the locking element 6 in order to prevent the locking element 6 from being too far too deep into the box 17 or into the cavity 9. If this were the case, this would have the disadvantage that the locking element 6 can no longer be brought into a sufficiently marausschbare position to ensure with him the primary lock in the contact chamber of the connector.
