Further, the fixing protrusion 362 of the fixing tab 360 of the connector position assurance member 300 is supported by the fastening portion 160 at the temporary locking position.

  The main purpose of the connector position assurance member 300 is to ensure that the electrical plug connector 100 and the mating electrical plug connector 200 are accurately interlocked during insertion and locking. In this case, the connector position assurance member 300 can only be moved from the temporary locking position (FIGS. 5 and 6) to the final locking position (see FIG. 7). The fixing tab 360 and the fastening portion 160 having the 362 allow the connector position assurance member 300 to be completely inserted into the receptacle 130 only when the electric plug connector 100 is in an appropriate plug-in position on the mating electric plug connector 200. The connector position assurance member 300 in the receptacle 130 is interlocked so that the lock can be released (that is, the locking position of the connector position assurance member 300 is determined by the complementary surfaces 262 and 162 of the protrusion 260 and the fastening portion 160). In the temporary locking position, on the other hand, the fixing protrusion 362 and the fastening portion 160 abut each other on the fixing surfaces 363 and 163 corresponding to each other and block each other in the direction in which the connector position assurance member 300 is inserted into the receptacle 130. .

  The fixing protrusion 362 is configured at a free end portion in the longitudinal direction of the fixing tab 360 of the connector position assurance member 300, and further, a fixing portion at the plug-in position shown in FIG. 7 of the electric plug connector 100 on the mating electric plug connector 200. 160 and the plug connector housing 101 prevent the electrical plug connector 100 from moving to an open position where the electrical plug connector 100 may be removed from the mating electrical plug connector 200.

  While the electric plug connector 100 is fitted to the mating electric plug connector 200 (when the process proceeds from FIG. 6 to FIG. 7), the engaging portion 160 of the plug connector housing 101 assists the protrusion 260 on the mating electric plug connector housing 201. It slides first along the surface 262 and returns to the support position when it completely exceeds the protrusion 260 (see FIGS. 6 and 7). The fixing projection 362 of the fixing tab 360 and the longitudinal end of the fixing tab 360 also move together. Once the protrusion 260 has passed, the fixed protrusion 362 can slide on the auxiliary surface 162 of the engaging portion 160. Due to the snapping-back of the projection 260 and the fastening portion 160 at the rear of the projection 260, the fixing surface 363 rides on the fastening portion 160, and the fixing surface 363 can slide on the auxiliary surface 162 of the fastening portion 160. This works because the clasp 160 and the protrusion 260 are at substantially the same height at the “common” surface, ie the joint between the two. Once the fastener 160 is exceeded, the securing protrusion 362 snaps to the rear of the fastener 160 in the locked position (see FIG. 7).

  In this position, the connector position assurance member 300 is in the final locking position in the receptacle 130 and the electrical plug connector 100 is no longer removed from the mating electrical plug connector 100. In this position, the connector position assurance member 300 is locked onto the shoulder 132 in or on the receptacle 130 by, for example, a lock lug 332. In the temporary locking position, the connector position assurance member 300 is locked in the receptacle 130, preferably with a lock hook 310 shown in FIG. Due to the two locks of the connector position assurance member 300 in the receptacle 130 (lock lug 332 and shoulder 132, lock hook 310 and receptacle 130), the connector position assurance member 300 is removed from the receptacle 130 in the temporary locking position. It is protected against separation and on the other hand is engaged in the fully locked position.

  For the function of inserting the connector position assurance member 300 into the receptacle 130 of the plug connector housing 101 or removing it from the receptacle 130, an arc portion 312 (see FIG. 1) integrally formed with the lock hook 310 is provided. Not connected to the fixed tab 360, the tab 360 is rather separated so as to be movable relative to the lock hook 310. Even if the tab 360 is lifted thereafter, the tab 360 can be moved from the engagement position with the arc portion 312 to each other, and the connector position assurance member 300 in the receptacle 130 can be disengaged.

  The connector position assurance member 300 further makes it difficult to remove the electric plug connector 100 from the mating electric plug connector 200. If desired, the connector position assurance member 300 is returned to the position shown in FIGS. First, in this case, the engagement of the connector position assurance member 300 with the receptacle 130 is disengaged, and then the fixing protrusion 362 of the fixing tab 360 is moved via the fastener 160 of the plug connector housing 101. . In this case, the mechanical contact between the fixing projection 362 and the fastener 160 is preferably not a complete locking connection, but rather a contact between two diagonal surfaces configured in the longitudinal direction L of the electrical plug-in connection 1. It is configured as a tangent. Thereafter, in the temporarily locked position of the connector position assurance member 300, the lock hook 310 re-engages with a contact surface of a recess (not shown) or a protrusion (not shown) on / in the receptacle 130. Thereafter, the fastening portion 160 is disengaged from the protrusion 260 of the mating electrical plug connector housing 201. Preferably, the connector position assurance member 300 is not removed from the receptacle 130, but rather remains in the temporarily locked position (4.5 mm).

  Lateral direction acting on plug connector housing 101 and / or receptacle 130 and / or part of connector position assurance member 300 protruding from receptacle 130 (perpendicular to longitudinal axis L of electrical plug-in connector 1) ), The engagement between the fastening portion 160 and the protrusion 260 can be released, so that the electric plug connector 100 can be detached from the mating electric plug connector 200. For this purpose, the fastener 160 is preferably materially connected to the plug connector housing 101 and / or receptacle 130 by at least one torsion bar (not shown). Therefore, due to the lateral force, the free end portion (fixing protrusion 362) of the fastening portion 160 and the fixing tab 360 is moved via the protrusion 260 of the mating electric plug connector 200, preferably via the two torsion bars. Will be.
