[Assembly procedure of the connector]

Next, an example of an assembly procedure of the connector 1 will be described. The stopper 40 is assembled from the left with respect to the housing 26 . Specifically, the stopper main body 43 is inserted into the stopper insertion hole 23 (see FIG. 10 ) while the front wall portion 40D is positioned along the front end of the housing 26 (see FIG. 11 ), thereby inserting the stopper 40 Installed on the casing 26 .

When the stopper main body 43 is inserted into the stopper insertion hole 23, the locked portion 24 of the housing 26 is locked with the locking recess 43G on the right side (top side) of the stopper main body 43 (see FIG. 10 ). .). Accordingly, the stopper 40 is held at the temporary locking position (see FIG. 9 ). At this time, each tab insertion hole 44 of the front wall portion 40D is shifted to the left relative to each terminal storage chamber 21, and each tab insertion hole 44 is blocked by the partition wall 29 between adjacent terminal storage chambers 21 (refer to FIG. 11.). Furthermore, each detachment prevention part 43F becomes the state retreated to the left side of the corresponding terminal accommodation chamber 21 (refer FIG. 12.). In this way, the stopper 40 held at the temporary locking position allows insertion of the female-side terminal fittings 10 into the respective terminal accommodation chambers 21 . At this time, each jig insertion hole 45 is in a state of matching with the front surface of the lance portion 22 (see FIG. 12 ). Accordingly, it is possible to insert the jigs into each jig insertion hole 45 and release the locking of the lance portion 22 .

Next, the female-side terminal fitting 10 fixed to the end of the electric wire W to which the rubber plug R is attached is inserted into the terminal accommodating chamber 21 from the rear of the terminal accommodating chamber 21 . In the process of inserting the female-side terminal fitting 10 into the terminal accommodating chamber 21 , the lance-shaped portion locking protrusion 17 collides with the lance-shaped portion 22 . Then, the lance portion 22 is flexed and deformed upward by the lance portion locking protrusion 17 . When the female-side terminal fitting 10 is inserted to the normal position, as shown in FIG. 13 , the lance 22 reaches the rear of the lance locking protrusion 17 and deforms back to its original state. Accordingly, even if the female terminal fitting 10 moves backward, the lance locking projection 17 is engaged with the lance 22 , whereby the female terminal fitting 10 is primarily locked in a detachment-prevented state. The rubber plug R is in close contact with the inner peripheral surface of the rear portion of the terminal housing chamber 21 .

At this time, the front surface of the female-side terminal fitting 10 is covered by the front wall portion 40D and is stopped at the front. Specifically, as shown in FIG. 14 , a portion between adjacent tab insertion holes 44 in the front wall portion 40D is entirely opposed to the front surface of the female-side terminal fitting 10 . In addition, between the adjacent protruding piece insertion holes 44 in the front wall portion 40D, and there is no tapered portion where the protruding piece insertion holes 44 are formed, the ratio of the left and right inner surfaces of the square tube portion 12 of the female side terminal part 10 is reduced. It is configured in such a way that it is basically covered by the inner side. The lance locking protrusion 17 faces the jig insertion hole 45 of the stopper 40 held at the temporary locking position (see FIG. 13 ).

As shown in FIG. 13 , the curved surface C of the female terminal part 10 inserted into the terminal receiving chamber 21 is continuous with the upper surface of the square tube part 12 and the front surface of the square tube part 12 and has a quarter arc shape. The curved surface C is disposed at the lower end portion of the jig insertion hole 45 so as to face the jig insertion hole 45 in a front view of the front wall portion 40D viewed from the front. Furthermore, at this time, the projection 17 for locking the lance is also disposed so as to face the jig insertion hole 45 . The lance locking protrusion 17 is a portion that is contacted by an inspection probe inserted through the jig insertion hole 45 during the conduction inspection for inspecting whether each female terminal component 10 is inserted into each terminal accommodating chamber 21 at a regular position.

After the insertion of all the female terminal fittings 10 into the terminal accommodating chambers 21 is completed, a conduction test is performed to check whether each female terminal fitting 10 is inserted into the proper position in each terminal accommodating chamber 21 . In the conduction inspection, the connector 1 in which the stopper 40 is assembled at the temporarily locked position is installed in the inspection device, and the inspection probe is inserted into the jig insertion hole 45 of the front wall portion 40D of the stopper 40 . , to determine whether or not it is in contact with the lance-shaped locking protrusion 17 of the female-side terminal component 10 .

Next, the stopper 40 held at the temporary locking position is moved to the permanent locking position. When the stopper 40 is pushed rightward from the temporary locking position, the locked portion 24 is disengaged from the locking recess 43G on the right side (top end side) of the stopper body main body 43 and is separated from the left side (base end side). ) is locked by the locking recess 43G (see FIG. 16.). Accordingly, the stopper 40 is held at the formal locking position (see FIG. 15 ).

With regard to the stopper 40 held at the formal locking position, each tab insertion hole 44 of the front wall portion 40D is matched with the front surface of the corresponding terminal storage chamber 21, and each anti-off portion 43F enters the corresponding terminal storage chamber 21. inside (see Figure 17.). Then, each detachment prevention part 43F is engaged with the step part 14 of the rear end edge of the square tube part 12 of the female side terminal fitting 10 (refer FIG. 19.). At this time, each jig insertion hole 45 is closed by the partition wall 29 which partitions the adjacent terminal accommodating chamber 21 (refer FIG. 18.).

In this way, the stopper 40 held at the regular locked position is locked with the female terminal fitting 10 inserted into the regular position in the terminal accommodating chamber 21 to prevent the female terminal fitting 10 from coming off. The female-side terminal fitting 10 is double-locked by the lance portion 22 and the detachment preventing portion 43F in a detachment-prevented state. In this way, the assembly of the connector 1 is completed. In addition, the stopper 40 can also move to the temporary locking position by moving leftward from the regular locking position. That is to say, the stopper 40 can be displaced between the temporary locking position and the formal locking position.

Here, when inserting the female terminal part 10 into the terminal receiving chamber 21, sometimes the female terminal part 10 is left in a state that has not reached the normal position (that is, a half-inserted state), and the operator still enters the stopper without noticing it. 40 The work of moving to the official locking position.

As shown in FIG. 20 , when the female-side terminal component 10 is left behind from the normal position, the rear end of the square tube 12 enters the stopper insertion hole 23 . When the stopper 40 is to be moved to the formal locking position in this state, the anti-falling part 43F collides with the rear end of the square tube part 12 that enters the stopper insertion hole 23 from the left, so that the stopper 40 can be restricted. The movement of the movable body 40 to the official locking position. Accordingly, the half-insertion state of the female-side terminal component 10 into the terminal accommodating chamber 21 can be detected.

Next, operations and effects of Embodiment 1 will be described.
