DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector suitable for smoothly connecting and disconnecting multipolar male and female connector housings from each other.

[0002]

BACKGROUND OF THE INVENTION The applicant of the present invention has disclosed a connector of this type in Japanese Patent Application No.
No. 215304. This will be briefly described with reference to FIGS. 19 and 20. A synthetic resin-made male connector housing 2 which forms one connector housing of the connector 1 is press-fitted with a synthetic resin-made substantially rectangular cylindrical hood cover 3 or the like. It is fixed by. This hood cover 3
Is slidably provided in a substantially rectangular tubular holder 5 made of synthetic resin and attached to an attached body such as a vehicle body panel (not shown). A flexible locking piece 4 having a rectangular engaging hole 4a is integrally formed on both sides of the hood cover 3. Further, on both sides of the holder 5, flexible arms 6 having projections 6a which are engaged with and disengaged from the engagement holes 4a are formed integrally at the ends.

[0003] A flexible locking piece 4 of the hood cover 3 is provided.
Projection 6a of the flexible arm 6 of the holder 5 in the engagement hole 4a
When the male connector housing 2 is temporarily locked, the hood portion 7a of the synthetic resin female connector housing 7 constituting the other connector housing is connected to the male connector housing 2 and the hood cover 3 in a fitting standby state (so-called standby state). Between the female connector housings 7
The flexible arm 6 of the holder 5 is
Of the male connector housing 2 and the holder 5 in the temporarily locked state. Thus, when the two connector housings 2 and 7 are fitted to each other, the two connector housings 2 and 7 are slidable toward the attached body with respect to the holder 5.

, The position of the male connector housing 2 with respect to the holder 5 at which the male connector housing 2 projects forward is restricted.

[0005]

In the prior art connector 1, the male connector housing 2 is detached when the two connector housings 2, 7 are disengaged by the stopper convex portion 3a of the hood cover 3 and the stopper receiving portion 5b of the holder 5. Although the stopper is used, as shown in FIG. 20, only the stopper receiving portion 5b of the holder 5 has an inverted tapered surface and the cross-sectional shape of the stopper convex portion 3a of the hood cover 3 is a right angle. The stopper holding force is weak, and the hood cover 3 may come off the holder 5.
Since slits are formed on both sides of the flexible arm 6 of the holder 5, the fitting opening side of the holder 5 is easily expanded, the stopper holding force in the detaching direction of the male connector housing 2 is weak, and the hood cover 3 is separated from the holder 5. There was a risk of coming off.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problem, and ensures that the cover is detached from the holder when the male and female connector housings are detached and when one of the connector housings is in a standby state for fitting. It is an object of the present invention to provide a connector that can prevent the occurrence of a connector.

Means for Solving the Problems The invention of claim 1 is a male,
One of the female and female connector housings is latched in the cover in a fitting standby state, and the temporarily locked holders are accommodated in the cover to accommodate the cover, and these holders and the cover are mounted. In a connector in which the other connector housing is detachably fitted to the one connector housing in the fitting standby state in the cover in the provisionally locked state, the cover is slidably provided in the holder, and The cover is provided with provisional locking means for holding the one connector housing in a fitting standby state, while a plurality of guide grooves are provided at a position of high rigidity on the inner wall side of the holder, and the guide groove on the outer wall side of the cover is provided. Stopper protrusions are provided at positions facing the respective guide grooves, and the front end of each of the guide grooves and the respective stopper protrusion are alternately provided. Are provided in the same direction, so that the reverse taper surface of the front end of each guide groove and the reverse taper surface of each stopper convex portion can freely contact each other when the one connector housing is in the fitting standby state. In this connector, the position of each guide groove of the holder for slidably storing the cover is set at a position where each stopper convex portion of the cover is difficult to come off in consideration of the balance of force. As a result, the retaining force of the stopper in the detaching direction of one connector housing is increased, so that the cover is reliably prevented from being detached from the holder due to deformation of the holder when the two connector housings are detached and when the one connector housing is in a standby state for fitting. .

According to a second aspect of the present invention, there is provided the connector according to the first aspect, wherein each of the guide grooves is provided in the vicinity of the lever on both sides of the upper center of the holder and the vicinity of the reinforcing portion on both sides of the lower part.
It is characterized by being provided for each part.

In this connector, since the positions of the guide grooves on the upper and lower sides of the holder are shifted from each other, erroneous assembly of the cover or the like in the holder is reliably prevented.

When the two connector housings 50 and 60 are detached from the completely fitted state of the two connector housings 50 and 60 shown in FIGS. 13 and 14 in maintenance and inspection, as shown in FIGS. To operate. That is,
Between the start of detachment of the two connector housings 50 and 60 shown in FIG. 14 and the detachment of the female and male terminals 53 and 63 shown in FIG. 17, the distal end portion 44 side of the lever 40 is located inside the hood 61 of the female connector housing 60. The lever 40 rotates in a direction opposite to that of the engagement when the lever 67 comes into contact with the projection 67a for the lever fulcrum of the rib 67, and comes off while pulling in the guide portion 54 of the male connector housing 50. Then, in the state shown in FIG. 17, the rib 67 in the hood portion 61 of the female connector housing 60 passes under the distal end portion 44 of the lever 40, and at the same time, the detachment of the female and male terminals 53 and 63 is completed. As a result, the lever operation of the lever 40 allows the female connector housing 60 to be easily detached from each other simply by a slide operation of pulling out the female connector housing 60 with a small operating force in the detaching direction.

As described above, the positions of the guide grooves 29 of the holder 20 that slidably accommodates the cover 30 are set to positions where the respective stopper projections 35 of the cover 30 are hard to come off in consideration of the balance of force. Is set near the portion where the male connector housing 50 is located), so that the stopper holding force in the detaching direction of the male connector housing 50 can be further improved, and when the two connector housings 50 and 60 are detached and the male connector housing 50 is fitted. In this state, it is possible to reliably prevent the cover 30 from coming off the holder 20 due to deformation of the holder 20. Further, as shown in FIG.
Since the positions of the guide grooves 29 on the upper and lower walls 20a and 20b are shifted from each other, the cover 30
Erroneous assembling can be reliably prevented, and overall assembling workability can be improved.

[0040]

As described above, according to the first aspect of the present invention, the position of each guide groove of the holder for slidably housing the cover is determined by taking into account the balance of force and the position of each stopper projection of the cover. Is set to a position where it is difficult to remove, so that the stopper holding force in the detaching direction of one connector housing is improved, and the cover is displaced from the holder by deformation of the holder when both connector housings are detached and when one connector housing is in the mating standby state. Detachment can be reliably prevented.

According to the invention of claim 2, on the holder,
Since the positions of the guide grooves on the lower side are respectively shifted, erroneous assembly of the cover or the like in the holder can be reliably prevented.
