Abstract

PURPOSE:To prevent a retainer from attaining the regularly retained position when a terminal metal piece is not inserted. CONSTITUTION:A connector housing 11 is fitted with a terminal sensing piece 18 which is contacted by a terminal metal piece 16 when it is inserted in the normal position in a cavity 13. When the metal piece 16 is inserted till the normal position, it contacts the sensing piece 18, and a retention part 19 protrudes outwards of the housing 11. If thereafter a retainer 20 is rotated to the retaining position, a hole provided in the retainer 20 is retained by the detention part of the sensing piece so that the retainer 20 is locked in the retaining position of the metal piece 16. When the metal piece 16 is not inserted, the retention part 19 of the sensing piece 16 remains out of protrusion, so that the retainer 20 will not be locked even though it is displaced to the retaining position.

SUMMARY OF THE INVENTION In a connector of this kind of construction, in order to make the assembly work of the connector efficient,
In general, the retainer 2 is attached to the connector housing 1 in advance so as to be in a temporarily locked state, and a large number of these connector housings 1 are carried into the terminal metal fitting 3 insertion work section so that the insertion work can be performed all at once. Is. However, in the above configuration, there is a problem that the retainer 2 that is temporarily locked to the connector housing 1 is likely to be in the main locked state due to vibration of the connector housing 1 during transportation. If the retainer 2 is in the fully locked state before the terminal fitting 3 is inserted, the terminal fitting 3 cannot be inserted, so it is necessary to pull out the retainer 2 to the temporary locking position. It is extremely troublesome and reduces work efficiency. In addition, as described above, the retainer 2
In order to prevent the
It is necessary to adopt a special container structure for the container for accommodating the connector housing 1 in which the retainer 2 is mounted in the temporarily locked state, which causes an increase in cost.

Next, the operation of this embodiment will be described. Now
It is assumed that the terminal fitting 16 is not inserted in the connector housing 11. In this state, the engaging portion 1 of the terminal detection piece 18
9 does not project outward from the housing body 12 as shown in FIG. Therefore, in this state, the retainer 20
Even if is rotated to the locking position, the engaging portion 19 of the terminal detecting piece 18 and the engaging hole 24 of the retainer 20 do not engage with each other, and there is no possibility that the retainer 20 is held at the locking position. Therefore, even if a large number of the retainers 20 are mounted in the connector housing 11 and are simply transported in a container, the retainer 20 will be vibrated during the transportation.
Is not locked at the locking position, and it is possible to reliably prevent the time and effort required to return the retainer 20 to its original position in the step of inserting the terminal fitting 16.

Next, when the connector housing 11 is transported to the insertion work section of the terminal fitting 16 and the work is performed, each terminal fitting 16 is inserted from the tip of the connector housing 1.
1 is sequentially inserted into the cavity 13 from the left side in the drawing.
Then, when the terminal fitting 16 is inserted, the tip of the lance 15 of the connector housing 11 is accordingly inserted into the terminal fitting 16.
It is elastically deformed so that it can be pushed down to the lower surface, and its entry is allowed. When the terminal fitting 16 reaches the regular position, the engaging hole 16a comes into contact with the engaging claw 15a of the lance 15, and the engaging claw 15a engages with the engaging hole 16a of the terminal fitting 16. The terminal fitting 16 is prevented from coming off. At the same time, with respect to the two terminal fittings 16 located in the cavities 13 on both the left and right sides, the side of the terminal fitting 16 is the terminal detection piece 1 of the connector housing 11.
Since it abuts on the bent portion 18a of No. 8, the terminal detection piece 18 is elastically deformed so as to be pushed outward, and the engaging portion 19 at the tip thereof projects to the outside of the housing body 12 (see FIG. 7).

Then, when the retainer 20 is pushed down from the top of the housing body 12 and rotated so as to cover the housing body 12, the lower surface of the retainer 20 on the tip side abuts on the engaging portion 19 of the terminal detecting piece 18. Upon contact, the left and right side wall portions are elastically expanded and deformed, and the engagement portion 19 reaches the engagement position where the left and right side wall portions of the retainer 20 cover the engagement portion 19 from both sides. As a result, the retainer 20 cannot rotate (see FIGS. 4 and 8). When the retainer 20 reaches the locking position in this way, as shown in FIG. 9, the locking projection 25 provided on the lower surface of the retainer 20 penetrates the through hole 21 formed in the housing body 12. Since it projects into the cavity 13, its vertical wall 25a engages with the shoulder 16b on the upper surface of the terminal fitting 16,
Therefore, the terminal fitting 16 is securely prevented from coming off.

Further, if the retainer 20 is pushed down in a state where the insertion position of the terminal fitting 16 is shallow and does not reach the proper position slightly, as shown in FIG.
The slanted surface portion 25c of the terminal abuts on the shoulder portion 16b of the terminal fitting 16,
The terminal fitting 16 is pushed forward (toward the hood portion 14). For this reason, the retainer 20 automatically pushes the terminal fitting 16 to the normal position, and the retainer 2 is securely held in the locking projection 25 when the terminal fitting 16 reaches the normal position.
0 is held in the locked position. The retainer 20 is provided with the elastic piece portion 26, and in the state of FIG. 3, the elastic force of the retainer 20 urges the retainer 20 toward the locking position (state of FIG. 8). It acts as an auxiliary force when rotating the retainer 20 in the locking position direction, and the work of pushing the terminal fitting 16 into the regular position becomes easy.

As described above, according to this embodiment, the retainer 20 can be held at the locking position only after the terminal fitting 16 is inserted into the connector housing 11, so that the connector housing 11 in which the terminal fitting 16 is not inserted is inserted. It is possible to reliably prevent the retainer 20 from being held at the locking position during transportation of the sheet. Therefore, the retainer 20 does not carelessly reach the locking position and it does not take time to release it, so that the work of inserting the terminal fitting 16 into the connector housing 11 can be streamlined, and the retainer 20 can be locked at the locking position during transportation. Therefore, a transport container having a special structure for preventing the above situation is not required, and the cost can be reduced. Further, particularly in the present embodiment, since the sloped portion 25c is formed on the locking projection 25 of the retainer 20, even if the terminal fitting 16 is not at the normal position, if the retainer 20 is pushed down, the sloped portion 25c will be formed. The terminal fitting 16 can be pushed into the normal position, and the retainer 2
By using 0, there is an effect that the work of inserting the terminal fitting 16 can be made more efficient. Further, in this embodiment, the elastic piece portion 26 is formed on the retainer 20, and the elastic force of the elastic piece portion 26 is used to push the terminal fitting 16 into the proper position. The effect that it can be performed more easily is also obtained.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the retainer is not limited to being attached to the connector housing in a rotating manner, and FIG.
As described in the related art example, it may be provided so as to be movable in the insertion / removal direction with respect to the connector housing. In short, a terminal detection piece for protruding the engaging portion on the connector housing based on the contact of the terminal fitting is provided. If the retainer is provided and the retainer is engaged with the engaging portion, the retainer can be held at the locking position only when the terminal fitting is inserted.
You will be able to achieve the intended purpose sufficiently.
