In this configuration, the terminal 2 is connected to the housing 1
By pressing the slope 3 of the elastic piece 5 by displacing the elastic piece 5 to allow the terminal 2 to be inserted, the elastic piece 5 is restored by elasticity, as shown in FIG. Then, the locking portion 4 is engaged with the locked portion 9 of the terminal 2 to detent the terminal 2. Thereafter, by rotating the stop piece 7 as shown by the arrow B in FIG. 4, the stop piece 7 is engaged with the base end portion 2a of the terminal 2 and the terminal 2 is detented. Therefore, in this case, the detent of the terminal 2 is doubled.

On the other hand, the one shown in FIG. 6 is also provided. In this embodiment, a stopper piece 15 is provided separately from an elastic piece 14 having a slope 12 and a locking portion 13 in a housing 11.

In this configuration, by inserting the terminal 16 into the housing 11 as shown by the arrow C, the slope portion 12 of the elastic piece 14 is pressed to displace the elastic piece 14 to insert the terminal 16 as described above. After the allowance, the elastic piece 14 is restored by elasticity, so that the locking portion 13 is engaged with the locked portion 17 of the terminal 16 as shown in FIG. And then
By pushing the stop piece 15 from the outside of the housing 11 as shown by an arrow D in FIG.
Detent. Therefore, even in this case, the detent of the terminal 16 is doubled.

[0006]

In each of the above-mentioned cases, the detent of the terminals 2 and 16 is doubled, so that the terminals 2 and 16 can be more reliably prevented from coming off. However, the assembling for the former involves, in the former, inserting the terminal 2 into the housing 1 and then turning the stopper piece 7, and in the latter, pushing the stopper piece 15 after inserting the terminal 16 into the housing 11. And both are 2
Operation was necessary and troublesome.

In these cases, when the terminals 2 and 16 are to be withdrawn from the housings 1 and 11 as necessary, in the former, the stopper 7 is returned to release the base end 2a of the terminal 2 from its engagement, and An operation of releasing the locked portion 9 from the engagement with the locking portion 4 by prying the piece 5 is necessary.
After releasing the convex portion 18 from the engagement, the operation of prying the elastic piece 14 to release the locked portion 17 from the engagement with the locking portion 13 is required, and both operations are required. It was troublesome.

The present invention has been made in view of the above-mentioned circumstances, and the object thereof is to provide a terminal in which the detent is doubled, so that both the assembling and extracting can be easily performed by one operation. An object of the present invention is to provide a connector for electric wiring.

[0009]

In order to achieve the above object, an electric wiring connector according to the present invention is configured by inserting a terminal into a housing. 1 has a slope portion and a first locking portion, and the first slope portion is displaced by being pressed by the insertion of the terminal to allow the terminal to be inserted, and then restored by elasticity. A first detent member that engages the first locking portion with the first locked portion of the terminal to detent the terminal;
A second slope portion provided in the housing and having a second slope portion in the direction of displacement of the first detent member, and a second locking portion in a direction opposite to the displacement direction; Is displaced by being pressed by the displacement of the first detent member to permit insertion of the terminal, and then restored by elasticity to engage the second locking portion with the second locked portion of the terminal. And a second detent member that detents the terminal together.

[0010]

According to the above means, when the terminal is inserted into the housing, the first detent member is displaced and restored to detent the terminal, and the first detent member is displaced and restored together with the first detent member. Since the second detent member is displaced and restored to detent the terminal, the detent of the terminal can be doubled by one operation of merely inserting the terminal into the housing.

In this state, if the first detent member is distorted by prying from the outside of the housing, the detent of the terminal by the first detent member can be released and the second detent member can be disengaged. Can be released to release the terminal detent by the second detent member. In short, a single operation of displacing the first detent member from the outside of the housing allows the double detent of the terminal to be released. Can be canceled at the same time.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. First, FIG.
And a terminal 22 before being inserted therein.
Among them, the housing 21 is made of plastic and has a hollow shape, and has a terminal insertion port 23 at one end on the right side in the figure and a mating terminal insertion port 24 at the other end on the left side.

A first detent member 25 and a second detent member 26 are provided inside the housing 21. Among them, the first detent member 25 is supported so as to be vertically displaceable by a support portion 27 protruding from the bottom of the housing 21. A first slope 28 having a gradually rising shape as shown in the figure is formed, and a first locking portion 29 is formed with a substantially vertical descent surface in front of the first slope 28, and a beak-shaped projection 30 is further formed in the front thereof.
Is formed.

On the other hand, the second detent members 26 are located on both sides of a portion near the tip of the first detent member 25 and project substantially vertically from the bottom of the housing 21. A gradually descending second slope portion 31 is formed by a convex portion 32 at a portion located immediately below the first detent member 25 and has a wall-like shape. Locking part 33
Is formed.

On the other hand, in this case, the terminal 22 is a female terminal corresponding to the male terminal (not shown), and is connected to the distal end of the lead wire 34 by a caulking 35. In the terminal 22, a first locked portion 36 is formed by a hole in the lower surface portion, and a second locked portion 37 is formed by a convex portion protruding downward from both sides of the lower surface portion. ing.

Now, in the case of the configuration as described above,
When the terminal 22 is inserted into the housing 21 from the terminal insertion port 23 as shown by an arrow E in FIG. 2, the first detent member 25 presses the first slope 28 from the tip of the terminal 22 by the lower surface. The terminal 22 is displaced downward as shown by an arrow F in FIG.
In addition, due to the downward displacement of the terminal 22, the second detent member 26 is moved to the second inclined surface portion 31 located ahead of the displacement direction.
Is pressed by the terminal 22 and is expanded and displaced as shown by an arrow G in the figure, thereby allowing the insertion of the terminal 22, especially the second locked portion 37 of the terminal 22.

Then, the terminal 22 is inserted by the insertion.
When the first locked portion 36 of the first detent member 36 has passed over the first slope portion 28 of the first detent member 25, as shown in FIG.
2 is released from pressing by 2 and restored by elasticity (up)
Then, the first locking portion 29 is engaged with the first locked portion 36 of the terminal 22 to stop the terminal 22 from returning. Further, by the restoration of the terminal 22, the second detent member 26 is released from the pressing by the terminal 22 and is restored (closed) by elasticity, and the second locking portion 33 is moved to the second position of the terminal 22. The terminal 22 is detented by engaging the locked portion 37 of the terminal 22. Thus, the detent of the terminal 22 is doubled.

On the other hand, from this state, if the tip depressed portion 30 of the first detent member 25 is pryed from outside the housing 21 to displace the first detent member 25 downward, the first locking portion 29 Is disengaged from the engagement position of the terminal 22 with the first locked portion 36 to release the detent of the terminal 22, and at the same time, the second detent is moved by the downward displacement of the first detent member 25. Since the stop member 26 is pressed against the second slope 31 and is expanded and displaced, the second locking portion 33 is thereby moved from the position where the second locking portion 33 is engaged with the second locked portion 37 of the terminal 22. The terminal 22 is released and the detent of the terminal 22 is released. Therefore, when the terminal 22 is removed from the housing 21 as necessary, the terminal 2
2 can be withdrawn.

As described above, in the present configuration, the double detent of the terminal 22 can be performed by one operation of merely inserting the terminal 22 into the housing 21, and the double detent of the terminal 22 is released. Can be performed by one operation of merely displacing the first detent member 25 from the outside of the housing 21, and each operation does not require two operations as in the prior art. Assembling for detent and removal for releasing the double detent can be easily performed by one operation, and workability can be improved.

The locking portions 29 and 33 and the locked portion 3
The specific shapes of 6, 37 are not limited to those described above. Also, the terminal 22 may be a male side instead of a female side. In addition, the present invention is not limited to the embodiment described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention.

[0021]

As is apparent from the above description, the electrical wiring connector of the present invention is provided with the first detent member for displacing and restoring the terminal by inserting the terminal into the housing to detent the terminal. And a second detent member for displacing and restoring the first detent member and restoring the terminal in the same manner as that of the first detent member, whereby the detent of the terminal is doubled. An excellent effect is achieved in that the assembling of the object and the extraction can be easily performed in one operation.
