Definitions

  • the invention relates to a housing for an electrical connector according to the preamble of claim 1.
  • a housing of the type mentioned at the beginning has already become known for plug contacts, such as plugs or sockets, which have a medium narrowing (US Pat. No. 3,686,619).
  • This known housing has the advantage that the resilient projection snaps into the constriction on the plug contact even after the plug-in contact has been loosely inserted into the through bore of the housing and holds it securely in its predetermined position. The locking then only needs to be taken care that the plug contact is not only elastically yielding, but rigidly positively secured. This is done in that the radial flexibility of the elastically engaging projection is canceled. Up to this final locking, the spring force inherent in the projection is sufficient to hold the plug contacts in the correct position in the through hole; this is during the further processing of the connector, such as. B. the test for electrical continuity or polarity reversal, desired.
  • the known housing either has a locking bolt which can be inserted transversely to the plugging direction or a locking member which can be inserted and locked axially into the housing from the plug end.
  • the proposed disk-shaped or plate-shaped design of the locking member can, however, only be used to a limited extent for such plug devices whose through openings for the plug contacts lie next to one another in one or two rows. Otherwise several such locking members are required.
  • efforts have also already been made to create a housing which enables the locking of plug contacts arranged side by side as desired (DE-U-7 739 743).
  • locking lugs have been proposed which are formed on a separate connecting plate which extends over the end face of the housing. This arrangement enables locking of plug contacts, which can be arranged at any point on the cross-sectional area of the housing.
  • this arrangement may lead to an undesirable extension of the connector housing; the housing also consists of at least two parts that have to be fitted together.
  • the invention is based on the object to provide a connector housing that is one-piece and compact, d. H. is as small as possible.
  • the training according to the invention leaves the designer many options for adaptation to the individual case; because he can connect the locking member to the housing where it does not interfere in the respective application. That is e.g. B. important in tight spaces when installing the connector.
  • the housing 1 comprises six through openings 2 to 7 for receiving plug contacts 8, which are designed as contact sockets.
  • the through openings 2 to 7 are formed in the region of the plug contacts 8 in part by radially elastically flexible sections 9 to 14 of the housing 1.
  • Sections 9 to 14 have projections 15 which engage behind the inserted plug contacts 8 in an elastically locking manner (FIG. 3).
  • the flexibility of the sections 9 to 14 of the housing 1 can be blocked by inserted locking members 16 to 19.
  • the locking members 16 to 19 are angular and integrally formed with the housing 1 and connected to the latter via film joints 20 to 23.
  • the first legs 24 to 27 are connected to the housing 1 via the film joints 20 to 23, while the second legs 28 to 31 protrude into the housing 1 through slots 32 in order to radially block the sections 9 to 14 there (FIG. 3). .
  • the locking members 16 to 19 serve with their legs 28 and 31 for locking one plug contact each.
  • the locking members 17 and 18 are each formed two legs 29 and 29 'or 30 and 30'. Each of the legs 29, 29 ', 30, 30' serves to lock a plug contact (not shown).
  • a plug contact 8 has been inserted into the through opening 2 (FIG. 3) from behind.
  • the plug contact 8 is connected to an electrical line (not shown), e.g. B. by crimping.
  • the here designed as a round plug socket 8 slides during insertion over a slope 33 of the projection 15 until the projection 15 can spring back radially behind the shoulder 34 of the plug contact 8 and pre-locks the plug contact 8, d. H. provisionally.
  • a paragraph 2a of the through opening 2 forms the front stop for the plug contact 8. After this pre-locking, the plug connection is checked electrically for polarity reversal, continuity, etc. If an error is found here, the plug contact can easily be removed again from the through opening 2 of the housing 1 and the error can be remedied.
  • the locking members 16 to 19 are brought into their end position: the second leg 28 of the locking member 16 is pushed into the slot 32 of the housing 1 by a folding movement - see arrow K in FIG. 2 - so that it is in the housing 1 comes to lie between a housing section 1 a and the elastic section 9, specifically as close as possible to the projection 15 (FIGS. 2 to 4).
  • This end position of the locking member 16 is shown in dash-dot lines in FIGS. 2 and 4.
  • the leg 28 can be held in the housing 1 by choosing a corresponding width of the slot 32.
  • a barb 35 is formed on the leg 28. The barb 35 latches behind the slot 32 and also holds the leg 28 positively in the housing 1 after the end locking (FIG. 4).
  • the plug contact 8 is then seated so firmly in the through opening 2 of the housing 1 that it can be removed unintentionally only by applying very high pull-out forces.
  • the design described ensures that the plug contact 8 is always properly seated in the through opening 2: If the plug contact 8 is not properly locked, e.g. B. since it was not inserted far enough or with the heel 34 towards the projection 15, it is not possible to insert the leg 28 into the housing 1 and latch it. In this case, the laterally bent elastic section 9 with the projection 15 blocks the space provided under the slot 32 for the leg 28, see FIG. 3. The protrusion of the leg 28 shows that the plug contact 8 is not inserted correctly , and the error can be rectified.
  • plug contacts for. B. find the use according to the aforementioned prior art.
  • the plug contacts only require a shoulder, an incision or the like, behind or into which the elastic, lockable section of the housing can engage.
