Definitions

  • the invention relates to a locking comb for an electrical connector made of injection-molded plastic, with a comb back and tines formed parallel to one another thereon.
  • a housing for electrical plug contacts with several adjacent continuous chambers for receiving and fixing plug contacts has become known, a locking comb with parallel prongs being inserted into a housing slot in order to lock the plug contacts in the housing.
  • the locking comb must be handled with care, since the molded tines of such a locking comb can be easily deformed.
  • electrical connectors are being manufactured in increasingly small cross-sections, preferably made of plastic, due to lack of space at the installation sites.
  • the individual components In order for the functionality to be maintained, the individual components must be small and fine. It is often difficult to create the necessary stability for assembly-related loads.
  • the locking element is processed by hand from the injection mold to the installation of a locking comb in the connector. Defects occur that relate to the shape stability of the comb, first on the relatively thin and long tines. On the one hand, costly and time-consuming additional production becomes necessary in the event of destruction, and on the other hand it is problematic to insert the prongs of the locking comb into the corresponding openings in the connector.
  • the object of the present invention is therefore to design a locking comb for an electrical connector which is easy to handle both before and during assembly in an electrical connector. It is desirable that the interlocking comb withstand all normal loads, e.g. H. has sufficient stability against interlocking and shape retention for the unproblematic insertion of the locking comb into the electrical connector.
  • the invention is based on the idea that a web between two adjacent prongs stiffens a locking comb to prevent deformations before and during assembly in the electrical connector.
  • a locking comb with several molded-on tines lying parallel to each other increases its basic stability with each additional web.
  • the tines of the locking comb can neither diverge nor converge and thus maintain the distances between them that are necessary for insertion into the connector. So that the comb can be inserted completely into the electrical connector element, it is advantageous to form the connection of the web to a prong with at least one predetermined breaking point. As soon as the web has fulfilled its function as a stabilizer and insertion aid, it abuts a housing part acting as a stop and breaks off in the direction of insertion when it is fed further.
  • Desired breaking points on the connections on both sides prevent the web from breaking out in an uncontrolled manner and, as a result, damage to the locking comb that would otherwise occur.
  • the locking comb can then act according to its locking positions.
  • the assembly staff can use the locking comb with little effort and time. If the locking comb is loaded abnormally before assembly and a web breaks out beforehand, it can still be used, however with the difficulties mentioned above.
  • the arrangement of the bar in the open, front third between the tines enables the locking comb to be extremely stable and functional. In order to maintain the shape of the tines with one another, a web is necessary immediately near the open end of the comb. In contrast, the front part of each tine must be free of irregular cross-sectional changes as an insertion aid.
  • the bar in the form of a rod.
  • the web runs parallel to the ridge back and preferably parallel to the stop surface of the connector housing. Both connections are loaded simultaneously when the web strikes, and consequently break through at the same time with the same dimensions. So it is not possible that the breaking out web in the Pushes insertion openings for the comb and the connector becomes inoperable. Tolerances between the tine and the insertion opening are only designed for differences caused by injection technology, so that the relatively large web cannot have any effect there.
  • the erecting web also allows the fitter to visually check whether the locking comb has been inserted correctly. The web falls z. B. in a collection container and is later processed in other manufacturing processes.
  • the electrical connector and the locking comb are designed with complementary locking means that can serve as single or double locking of the housing parts.
  • Figure 1 shows in principle a 35-pin electrical connector 1 known from the prior art, which is mainly composed of a seal 2, a housing 3 and a contact carrier 4.
  • the seal 2 encloses a housing opening 5, into which a line bundle, not shown, can be inserted and thus sealed.
  • a contact carrier 4 is inserted in the housing 3, in which a plurality of adjacent continuous chambers for receiving and fixing contact elements are formed.
  • a contact element 7 struck on a line 6 is inserted into one of the chambers 8 and secured by a locking comb 9 which can be displaced in the longitudinal direction of the contact carrier 4.
  • This comb 9 lies against a projecting shoulder 10 of the contact element 7 and thus prevents the same from moving backward.
  • the contact element 7 can also be primarily locked in the contact carrier 4 by means of a known spring locking element 11 or the like (see FIG. 2).
  • An interlocking comb 9 consists of a comb back 12 and two long, thin tines 13 formed thereon.
  • the ratio length l of the prong 13 to width b of the comb back 12 is 13: 1 here and can certainly reach even higher values.
  • Each tine 13 has a continuously square cross section, which changes only in the vicinity of the ridge 12 by a nose-shaped locking means 14. This tine shape is the easiest to implement by injection molding.
  • the distance a between the two prongs 13 is of course matched to the requirement of the electrical connector 1.
  • a rod-shaped web 16 is arranged in the open, front third 15 between the prongs 13 (FIGS. 3 and 4).
  • connection 17 of the web 16 to the prong 13 is shown in detail on an enlarged scale in FIG. It is expedient to design the predetermined breaking point 18 with a cross section of approximately 0.2 mm, so that the function is retained and the production is unproblematic.
  • the locking comb 9 can be used.
  • the tines 13 are easily and precisely inserted into the corresponding openings 19 of the contact carrier 4 and the comb 9 is pushed further in the insertion direction S.
  • the now superfluous web 16 strikes between the prongs 13 on the contact carrier 4, the predetermined breaking points 18 break and the web 16 falls z. B. in a container, not shown.
  • the comb 9 is pushed to the end position, ie the locking lugs 14 interact with complementary locking surfaces 20 and the secondary locking of the contact elements 7 is ensured (FIGS. 6 and 7).
