Definitions

  • the invention relates to a connector which can be plugged together with a mating connector, according to the features of the preamble of claim 1.
  • the primary locking takes place, for example, between the contact partner and a corresponding inner contour of the contact chamber. This is done, for example, in that the contact partner has a protruding spring tab which engages (engages) in a corresponding recess in the inner contour in the contact chamber when the contact partner has been arranged in its intended end position in its contact chamber. This already effectively prevents the contact partner from being able to move out of its contact chamber, be it from external influences (such as vibrations) that may occur during normal use of the connector. As a rule, however, this primary lock is not sufficient to absorb unusual loads on the contact partner, what the secondary locking is intended.
  • Such secondary locking is realized for example with an additional locking element, which is also referred to as a bar or CPA (Contact Position Assurance).
  • CPA Contact Position Assurance
  • the secondary locking is then realized in that the locking element, which is initially not arranged on the connector or is in a Vorverrastrus on the connector, in particular its contact carrier is moved to an end position (Endverrastrus), in particular is displaced so that thereby the secondary locking tab the contact partner comes to rest on the locking element, which ensures that the contact partner can not be moved out of its contact chamber.
  • Such a connector with a primary lock and a secondary locking means of a bolt is known from DE 10 2016 208 673 known.
  • the invention has for its object to provide a connector of a connector, which can be mated with a mating connector and which is arranged at one end of a cable, can be achieved with the higher holding forces and withstands the appropriate test specifications.
  • the secondary locking tab is reinforced by a further element, namely a securing web interacting with the locking element on the contact partner.
  • a further element namely a securing web interacting with the locking element on the contact partner.
  • the connector according to the invention satisfies a test specification LV214 specified by automobile manufacturers, in which it is defined that a contact partner outgoing force from the housing or its contact chamber must be greater than 55 Newton with respect to only the secondary locking.
  • secondary locking tab is used to represent each geometry of the contact partner, which is suitable and intended to realize a secondary locking of the contact partner in its contact chamber. It can also be a paragraph, a block or the like, so that the secondary lock does not have to be designed or not just as a tab.
  • the securing web is arranged and aligned in the longitudinal direction of the contact partner on this.
  • the secondary locking tab is arranged and oriented, for example, transversely to the longitudinal direction of the contact partner (this arrangement and orientation is sufficient for a certain amount of holding forces)
  • the securing web according to the invention is aligned in the longitudinal direction, so that an overall higher stability of the entire contact partner and Thus, a much better transmission of tensile stresses on the contact over his Securing ridge is achieved on the locking element.
  • such an elongated securing web aligned in the longitudinal direction of the contact partner can be realized particularly easily if the contact partner is produced in a stamping and bending process (or possibly also in a punch rolling process).
  • the securing web and the secondary locking tab are angled aligned and arranged.
  • such an arrangement can again be produced simply, quickly and inexpensively in a stamped bending process or a comparable process.
  • holding forces up to a certain order of magnitude are realized with the secondary locking tab, which normally do not occur in practice or during the test of the connector.
  • the securing web is arranged in a different direction than the secondary locking tab and aligned to intercept these increased holding forces can.
  • the securing web and the secondary locking tab are aligned and arranged at approximately 90 degrees, exactly 90 degrees to each other.
  • Such an arrangement advantageously results in a simple production, since an angling in a punch bending process is very easy to implement.
  • the contact partner can be much better supported on the locking element to increase the holding forces, than if these two elements (securing web and secondary locking tab)
  • the locking element has a cooperating with the securing web and the secondary locking tab contact securing end.
  • This contact securing end causes a contact of the securing web and the secondary locking tab on the locking element, if this has been moved from a first position, in particular its Vorverrast ein, in the end position, in particular its Endverrast ein.
  • the contact partner Before the movement of the locking element from its first position to its Endverrast ein, it is possible to use the contact partner in its contact chamber. This would not be possible if the locking element would already be in its Endverrast ein on or in the connector, more precisely on or in the contact carrier of the connector. This means that the contact partner must first be inserted into its contact chamber before the locking element can be brought into its Endverrast ein.
  • This has the additional advantage that it is ensured in any case that the function of the locking element is realized when the contact partner has been used as intended in its contact chamber. This is not possible before in the event that the locking element would already be in its Endverrast ein. This additionally gives an increased ease of installation.
  • the contact-securing end is L-shaped.
  • two contact surfaces are realized, namely on the one hand a contact surface for the secondary locking tab and on the other a contact surface for the securing web, preferably an end face of the securing web.
  • the locking element and / or the contact carrier has a guide surface on which the contact partner slides during insertion into its contact chamber.
  • This guide surface thus facilitates the insertion of the contact partner in its associated contact chamber. It is particularly advantageous if, during the insertion process of the contact partner into its contact chamber, not only the contact carrier has a corresponding guide surface, but even if the locking element is already fixed in its Vorverrast ein on the contact carrier and in turn also has a guide surface for the contact partner.
  • a further common guide surface is available during the sliding of the contact partner when it is inserted into its contact chamber.
  • the insertion of the contact partner is increased in its contact chamber, if not only a respective guide surface of the contact carrier and the locking element are available, but if the guide surfaces are aligned in the Vorverrast ein of the locking element to each other.
  • An inventive connector is in various views and details in the FIGS. 1 to 41 shown and described below.
  • FIGS. 1 to 9 is, as far as shown in detail, a contact carrier 1 shown in different views.
  • This contact carrier 1 is part of a connector, not shown.
  • the contact carrier 1 has at least one contact chamber, in this embodiment, two adjacent contact chambers 2. It is also possible to provide more than two contact chambers in a row or else a plurality of contact chambers in rows one above the other, ie parallel to one another.
  • the contact carrier 1 has a receiving geometry 3 ( FIG. 5 ), in which still a darches and described locking element for a secondary locking can be used.
  • the contact carrier 1 has a cable outlet end 4 and at its opposite end a mating face 5.
  • an unillustrated electrical cable is inserted, wherein at each electrical conductor of the cable, a contact partner is arranged, which is inserted from the cable outlet end 4 in the direction of the contact carrier 1 and fixed there.
  • an unillustrated mating connector preferably the contact carrier, is inserted into the contact carrier 1.
  • a connector consisting of connectors and mating connector, wherein each contact partner of the connector with each contact partner of the mating connector corresponds and is plugged together to make an electrical connection.
  • FIGS. 8 and 9 show sections through the contact carrier 1 according to the FIGS. 5 and 6 .
  • FIGS. 10 and 11 are again shown the contact carrier 1, in which for the secondary locking a locking element 6 can be used in a direction of insertion ER. While in FIG. 10 is shown that the locking element 6 has not been used in the contact carrier 1 and there preferably brought into a Vorverrast ein is in FIG. 11 illustrated that the locking element 6 was inserted in the insertion direction ER in the interior of the contact carrier 1, in particular in the direction of its receiving geometry 3 and set in a Vorverrast ein there. The locking element 6 is located in the illustration in FIG. 11 not yet in its Vorverrast ein. This is achieved only when the locking element 6 (also referred to as a bar) completely mounted on its end stop in the contact carrier 1 (inserted and locked) was.
  • a bar also referred to as a bar
  • the locking element 6 geometries, which are adapted to the receiving geometry in the interior of the contact carrier 1 on the one hand. These geometries cause a guided insertion of the locking element 6 in the receiving geometry 3 of the contact carrier 1 in Insertion direction ER.
  • FIG. 18 the situation is shown in which the locking element 6 has been arranged in its Vorverrast ein within the contact carrier 1.
  • the contact carrier 1 also referred to as a plug sleeve
  • the locking element 6 locks in the area marked with the rectangle (latching area VB).
  • latching element Vorverrast- and Endverrast ein
  • FIGS. 19 to 24 is shown in various views that the locking element 6 is in the Vorverrast ein within the contact carrier. This makes it possible for each contact partner (not yet shown here) to be inserted into its associated contact chamber 2 within the contact carrier 1, specifically from the direction of the cable outlet end 4 in the direction of the mating face 5.
  • an exemplary embodiment of an electrical contact partner 7 is shown, which is preferably produced in a stamping bending process or in a punch rolling process.
  • This contact partner 7 has, for example, a contact pin 8, which is arranged in the region of the mating face 5 within the contact carrier 1, that is, it protrudes from the contact chamber 2.
  • a contacting region 9 is shown, which is adapted and adapted to the contact partner 7 in a suitable manner to define an electrical conductor. This can be realized, for example, by soldering or welding or else by a crimp connection.
  • the contact partner has an element for primary locking, with which it can be primarily locked within the contact chamber 2 of the contact carrier 1 when it is in its intended, that is final position within the contact chamber 2 after insertion ,
  • the element for this purpose is designed as a primary locking tab 10 which protrudes from the contact partner 7. If the contact partner 7 is inserted into its contact chamber 2, the primary locking tab 10 is elastically deformed and slides with its end against the inner contour of the contact chamber 2.
  • a stop 11 may be present, which comes to rest at one end of the contact chamber 2 when the contact partner 7 has been used in its end position in its contact chamber 2 is.
  • FIG. 30 is shown how the contact partner 7 is inserted in its contact chamber 2 of the contact carrier 1 and, above all, the secondary locking elements cooperate with the locking element 6.
  • the secondary locking tab 12 and the securing bar 13 can be seen.
  • the locking element 6 has a contact-securing end 14.
  • This contact securing end 14 of the locking element 6 in its Endverrast ein causes not only the secondary locking tab 12 at least partially, possibly also completely, but also the securing web 13, in particular its end face, which faces in the longitudinal direction of the contact 7 rests against this contact securing end 14.
  • FIGS. 31 and 32 The sake of completeness is in the FIGS. 31 and 32 the locking element 6 is shown in its Vorverrast ein in the contact carrier 1, and once from view of the mating face 5 (Fig. FIG. 31 ) and once to the cable outlet end 4 ( FIG. 32 ).
  • FIGS. 34 and 35 show analogous to the FIGS. 31 and 32 the locking member 6 in its Endverrast ein, which is clear from the drawn rectangles that not only the locking member 6 has been moved, but that thereby the contact securing end 14 has been effective for the sake of clarity not shown here contact partner.
  • the respective contact chamber 2 has a guide surface 15 and also the locking element 6 has its own guide surface 16.
  • these two guide surfaces 15, 16 are arranged in alignment with each other, which is particularly in FIG. 22 is very recognizable.
  • the guide surface 16 is in the FIG. 16 seen above (EinInstitutfase on the left side of the respective secondary locking bar).
  • the plug itself has no sealing element.
  • the seal is made in each case only on the single core seals on the contact partners of plug and mating connectors (especially pin and socket contacts) and a seal between plug and mating connector.
  • FIGS. 36 and 37 another embodiment of the contact carrier 2 is shown. This includes the locking element 6, which in the FIGS. 38 to 41 is shown. Although the geometry of contact carrier 2 and Locking element 6 in the FIGS. 36 to 41 is something different than in the embodiment, which in the FIGS. 1 to 35 is shown, the same operation and direction is nevertheless realized.
