  • WO 2013/064573 A1 discloses a connector and associated TPA, the TPA having a flexible tab configured to be locked in the connector in a standby position when no terminal is inserted into the connector and to be deflected by the terminal upon insertion into the connector.
  • TPA devices can be placed in their active position in the box even if no terminal is actually mounted in the box.
  • the function of a TPA also consists in preventing any connection with a complementary connector, when the TPA is not in the active position, any attempt to couple a complementary connector box failing due to the presence of a dedicated part at the front of the TPA against which the additional connector box abuts.
  • the object of the invention is to meet this need at least in part.
  • the invention relates to a connector housing according to claim 1.
  • the flexible lug is also configured to be locked inside the first housing of the case body when the TPA is in its active position.
  • the flexible tab is adapted so that, when it is blocked in its standby position, it does not allow the sliding of the TPA device towards its active position if no terminal insertion is carried out in the housing. .
  • the invention consists in defining a connector whose TPA mounted sliding inside the box, transversely to its axis is activated only by the insertion of a cable terminal whose body comes to unlock one or more flexible legs of the TPA previously in abutment against the case.
  • the solution according to the invention makes it possible to prevent any activation of the TPA if no cable terminal is inserted in the box equipped with the TPA, and consequently the connection between two complementary connectors.
  • a TPA according to the invention can only be activated on the condition that the terminal is actually housed in its box.
  • connection between two complementary connectors can only be made if the two terminals are correctly inserted in the receiving boxes of this pair of complementary connectors.
  • the TPA according to the invention therefore provides additional security compared with the TPAs according to the state of the art.
  • the flexible tab is arranged in such a way that it projects at least partially into the central passage of the case when it is in its standby position and is housed entirely in the wall of the case. in active position.
  • the flexible lug is adapted so that, when it is blocked in its standby position, it does not allow the TPA device to slide towards its locking position if no terminal is inserted into the housing.
  • each flexible lug includes a chamfer at its free end, adapted to facilitate insertion of the conductor into the box.
  • the connector comprises a so-called connector position assurance device (CPA), adapted to secure the locking of a complementary connector coupled with the connector.
  • CPA connector position assurance device
  • the invention also relates to a method for mounting a cable terminal in a connector as described above according to claim 8.

  • a terminal position (“ Terminal Position Assurance ” in English, acronym TPA).
  • Another device 4 called connector position insurance (“Connector Position Insurance " in English acronym CPA) is slidably mounted in the housing 10.
  • the CPA device is not mandatory and the TPA device can be alone here.
  • CPA 4 device is described and claimed in the patent application entitled “Connector housing equipped with an improved connector position assurance device (CPA) ", filed in the name of the applicant, on the same day as the present application. .
  • the conductor 30 of the terminal 3 is intended to be connected by coupling with a conductor 20 of a complementary connector 2, by the front face 11 of the body of the box 10.
  • the conductor 30 is held inside a barrel 100 at the within the connector housing 10.
  • the body 31 of the terminal 3 is locked inside the box 10 and the cable 32 of the terminal emerges from the body of the box 10 by its rear face 12.
  • the body 31 of the terminal 3 includes a locking pin 33 which protrudes outside.
  • the figure 4 illustrates a male box 50, complementary to the female box 10 with its removable device TPA 2 in the standby position.
  • the body 31 of a terminal 3 is locked and secured inside the box 50 and the cable 32 of the terminal emerges from the box 50 via its rear face 52.
  • the body of the case 10, 50 comprises retaining and locking lugs 13 molded.
  • These retaining and locking lugs 13 are adapted to cooperate by snap-fastening with the flexible tabs 22 of the TPA device 2 on the one hand to retain the latter on the box 10, 50 in its locking waiting position and on the other hand to hold it and lock it in its active locking securing position.
  • the case body 10, 50 also comprises first housings 14, in the form of outwardly opening grooves, adapted to house the flexible tabs 21 of the TPA 2 in its active position, as well as a second housing also open on the outside adapted to house the abutment protrusion 23 of the TPA, as detailed below.
  • the TPA 2 device made in one piece, is mounted in the box 10, between a standby position and an active position, as explained below.
  • the TPA 2 device essentially comprises a head 20 with a manual support zone.
  • Two flexible tabs 21, preferably identical, are connected to the head 20, on either side and at the front end thereof. As explained, these flexible lugs 21 have the function of blocking the TPA device 2 in translation against the case 10 in its unlocking waiting position.
  • Two flexible tongues 22, preferably identical, are also connected to the head 20 on either side and to the rear end thereof.
  • Each of these tongues 22 comprises two openings 220 corresponding either to the standby position or to the active position.
  • These retaining and locking openings 220 are each adapted to snap around a retaining and locking lug 13 of the case 10, so as to retain the TPA device 2 both in its standby position and in lock and lock it to the box 10.
  • Step a/ A cable terminal 3 is placed on the rear face 12 of a housing 10 of a connector.
  • the TPA 2 device is in the locking waiting position ( Figure 7A ).
  • the openings 220 are snapped around the retaining lugs 13 on the top of the box 10, and thus retain the TPA device 2 in this standby position, which is the position farthest from the box 10.
