Definitions

  • the present invention is based on an electrical connector part designed according to the preamble of the main claim.
  • Such electrical plug-in connection parts are provided in particular in order to create a releasable electrical connection to a mating plug-in connection part via their plug contact elements connected to electrical lines.
  • the mating connector part can e.g. also be connected to an electrical line or directly connected to an electrical unit.
  • an electrical connector part corresponding to the preamble of the main claim has become known.
  • the electrical plug contact elements are introduced into receiving chambers of the housing, which is provided with a locking arm for each receiving chamber.
  • each locking arm can be of one Unlocking position are brought into a locking position.
  • two spring arms are formed on the electrical plug-in contact elements, which come to rest behind locking projections formed on the walls of the associated receiving chamber, so that the electrical plug-in contact elements located in the receiving chambers are kept primarily secured. If an electrical connector element is to be removed from its receiving chamber, a tool is inserted into the associated receiving chamber via appropriate accesses, whereby the primary locking is released. In order to be able to remove the plug contact element from its receiving chamber, however, the secondary locking must also be released by a further work step.
  • an electrical plug connector in the receiving chambers for locking inserted plug contact elements there are elastically deflectable locking arms.
  • the locking arms are molded onto a housing wall and come to rest with their free end against a projection of the associated plug contact elements for locking.
  • a spacer block is inserted into the interior of the connector part from the plug side, which allows elastic deflection of the locking arms in a first position and which blocks the deflectability of the locking arms in a second position.
  • the spacer block must first be brought back into its first position; only then can a tool be inserted into the interior of the plug-in connection part to deflect the locking arm and the relevant plug-in contact element can be removed from its receiving chamber. Because of completely missing housing and Measures on the plug contact element side, however, only a single locking measure for the plug contact elements can be implemented by means of such a plug connection part. In order to cancel this locking, which relates only to a locking measure, however, several work steps are necessary.
  • the object of the present invention is to further develop an electrical plug connection part in such a way that both the primary and the secondary locking are released by the insertion of a single tool in a single work step and thus a quick, simple removal of electrical plug contact elements from their receiving chambers is possible.
  • the object is achieved in an electrical connector part of the type mentioned by the features specified in the characterizing part of the main claim.
  • such an electrical plug connection part mainly consists of a housing 1 made of plastic in which there is at least one receiving chamber 3 provided for receiving an associated electrical plug contact element 2.
  • a receiving chamber 3 provided for receiving an associated electrical plug contact element 2.
  • an opening 4 for each receiving chamber 3 with a locking arm 5 arranged therein and integrally molded on one side onto this outer housing wall.
  • each plug-in contact element 2 located in the receiving chambers 3 of the housing 1 must be securely held in the same, so that their functionality is guaranteed after the plug-in connection part has been connected to its counter-plug-in connection part.
  • each plug-in contact element 2 has two molded-on spring arms 6, each of which comes to rest behind a locking shoulder 7 molded onto the walls of the associated receiving chambers 3. Place the two spring arms 6 and the two locking shoulders 7 With regard to the necessary securing of the position of the electrical plug-in contact element 2, the so-called primary securing is provided.
  • each electrical plug-in contact element 2 is additionally secured for securing the position between an end stop 8 formed on the mouth region 13 of the associated receiving chamber 3 and the locking arm 5 brought into its locking position.
  • Each locking arm 5 is movably formed on an outer housing wall of the housing 1 via a film hinge 9.
  • all locking arms 5 are part of a single outer housing wall, whereas, in the case of double-row plug-in connection parts, the locking arms 5 are part of two opposite outer housing walls of the housing 1.
  • the locking arm 5 is essentially L-shaped and comes with its short leg behind the securing lugs 10 molded onto the associated plug contact element.
  • a reset slope 11 is formed in the short leg of the locking arm 5, which essentially represents an extension of the long leg in its contour and extends on one side over the entire width of the short leg.
  • two grooves 12 are formed in the receiving chamber 3. The two groove-like accesses 12 start from the mouth area 13 of the receiving chamber 3 and extend along two opposite inner walls to the two molded locking heels 7.
  • a groove-shaped further access 14 which extends from the mouth area 13 and extends parallel to the receiving chamber 3 and leads into the opening 4, is formed in the housing 1.
  • the tool 15 is fork-shaped and has three fork tines 16.
  • the tool 15 is inserted into the housing 1 with its three fork tines 16.
  • Two fork tines 16 are inserted into the two groove-like accesses 12 and ultimately thereby reset the two spring arms 6 of the plug contact element 2.
  • a fork tine 16 is simultaneously inserted into the further access 14 and ultimately thereby resets the locking arm 5 from its locking position to its unlocking position.
  • the resetting of the locking arm 5 is brought about because the fork tines 16 inserted into the groove-like further access 14 initially come to rest with the free end against the reset slope 11 and when the tool 15 is inserted further the locking arm 5 via its reset slope 11 more and more from the cross section of the receiving chamber 3. Ultimately, the cross section of the receiving chamber 3 is completely released again, so that the electrical plug contact element 2 because of the simultaneous cancellation of the primary and Secondary fuse can be removed quickly and easily from its receiving chamber 3.
  • the fork tines 16 assigned to the groove-like further access 14 are designed somewhat longer than the two other fork tines 16.
