DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention is a pair of female, also relates to a lever coupling type connector coupling of the male connector carried by the rotation of the lever provided on the cam member of.

[0002]

2. Description of the Related Art In FIG. 7, a is a female connector, b is a male connector, c is a rotary cam plate, and a rotary cam plate c has a pair of drive cam grooves e, e around a rotary shaft d. 'the provided in point symmetry is that you had engagement flange d ₁ is provided at the tip of the rotation shaft d, the engagement Tometsuba d ₁ on the inner side of the pin guide notch f formed in the longitudinal direction of the female connector a By engaging, the rotation shaft d or the rotation cam plate c is provided so as to be movable along the pin guide notch f. A driven pin g is projected from the front end of the male connector b, and a driven pin g 'is projected from the rear end of the female connector a.

With the rotating shaft d engaged with the pin guide groove f and the driving cam groove e 'previously engaged with the driven pin g', the rotating cam plate c is provided on the female connector a, and the drive is performed. Upon insertion of the male connector b into the female connector a state where the inlet e ₁ coincides with the pin guide notch f of the cam grooves e, the driven pin g
There enters the inlet _{e 1} of the driving cam groove e (FIG. 8 (A)).
When the rotating cam plate c is rotated in this state, the driving cam grooves e,
e 'draws the driven pins g and g' (FIG. 8B),
At this time, the rotating shaft d pulls the female and male connectors a and b twice while moving the pin guide notch f by themselves, and completely fits them (FIG. 8C).

In this structure, since the rotating cam plate c or the driven pin g is provided only on one side of the female and male connectors a and b, the male connector b on the driven side is provided.
Tend to be inserted obliquely, and as the number of poles of the terminal increases, the resistance increases and the fitting becomes more difficult (see FIG. 9).

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention is to prevent the oblique insertion of a driven connector while using a double-fitting drive mechanism using a rotating cam member.

[0006]

To achieve the above object, according to an aspect of, the present invention, the male connector B with the driving pin 6, and the female connector A with 4 notches pin guide and the driven pin 6 ' , dial rotation lever C having a pair of driving cam grooves 2, 2 'in the longitudinal side of the rotation shaft 1 in the operating section C pair of rotating cam plate C 2 which faces provided on both sides of the _1, C ₂ from made, with respect to the female connector a to dial rotating lever C provided in movable state shafts to 1 longitudinal direction times, you to the initial position operating section C ₁ is in contact with the female connector a
The driven pin 6 'projecting from the female connector A is
At the inlet 2a 'of the drive cam groove 2'.
Inlet 2a matches the notch pin guide 4, dial rotating lever C driving cam grooves of a pair Te rotation when the smell of 2,2 'is the <br/> drive pin 6, 6' via the female Connector A and male connector B
The structure which drives the fitting of was adopted.

[0007]

A pair of rotating cam plates provided opposite to each other uniformly drive both sides of the male connector.

[0008]

In FIG. 1, A is a female connector, B is a male connector, and a dial rotating lever C is provided on the female connector A so as to be rotatable about a rotating shaft 1. As shown in FIG. 3, the dial rotation lever C is provided with a pair of rotation cam plate portions C ₂ and C ₂ on both sides of the operation portion C _{1 so} as to face each other.
In each of the rotating cam plates C ₂ , C ₂ , a pair of driving cam grooves 2, 2 ′ are provided point-symmetrically about the rotating shaft 1, and a locking flange 1 a is provided at the tip of the rotating shaft 1. The locking flange 1a is engaged with the inside of the pin guide notch 4 formed in the front-rear direction in the body 3 of the female connector A so that the rotating shaft 1 is movable in the pin guide notch 4, in those on the female connector a is provided a dial rotating lever C (see FIG. 1), the operation unit
C ₁ is driven cam groove 2 is in contact with the female connector A '
A driven pin 6 ′ projecting from the female connector A over the tapered step 5 provided at the entrance 2 a ′ of
The initial position of the dial rotation lever C is set.

In the initial position, the entrance 2a of the drive cam groove 2 is aligned with the pin guide notch 4 (see FIG. 1), and in this state, the male connector B is inserted into the sleeve 3 of the female connector A. When inserted, the driven pins 6 projecting from both sides of the male connector B enter the entrance 2a of the driving cam groove 2 together with the pin guide notches 4 (FIG. 4A).

[0010] Here, the female operation unit _{C 1} by the driving cam groove to rotate the dial rotational lever C in the arrow P direction 2, 2 'driven pin 6, 6' via the male connector A, B Are attracted to each other (FIGS. 4 (B) and 4 (C)) to reach a completely fitted state (FIG. 4 (D)). As shown in FIGS. 5A and 5B, female and male connectors A ',
In the fitting operation of the B ', the distance L ₁ between the rotary shaft 1 and the driven pin 6 during the initial fitting (FIG. 5 (A)), in the post-fitting end becomes the distance L ₂ (Fig. 5
(B)), in the case of the present invention, the distance L _1/2 between the rotating shaft 1 and the driven pin 6 at the time of initial fitting is (FIG. 6A)
After the completion of the fitting by the same fitting stroke, L ₂ /
In the same fitting stroke, the degree of rotation of the rotating shaft 1 is １ ／ of that in the conventional case.

[0011]

According to the present invention, as described above, the driven pin 6
And the female connector A having the male connector B, and cutouts 4 for pin guide and the driven pin 6 'have, set on either side of the operating portion C ₁
Consists dial pivoting lever C having a pair of driving cam grooves 2, 2 'in the pair of rotating cam plate portion C _2, C ₂ which faces digits before and after side of the rotation shaft 1, dial rotating lever C
The provided in movable state shafts to 1 longitudinal direction times with respect to the female connector A, the operation unit C ₁ is abutted to the female connector A
Driven at the initial position
When the pin 6 'is located at the entrance 2a' of the drive cam groove 2 ',
The entrance 2a of the drive cam groove 2 coincides with the notch 4 for pin guide
And, fitting dial rotating lever C driving cam grooves of a pair Te rotation when the smell of 2,2 'are driven pin 6, 6' of the female connector <br/> data A and the male connector B through the Because it drives
And without tilting the male connector B by dialing pivot lever C can be smoothly fitted operation, also it is possible to reduce the rotational travel of dial rotation lever C, to be capable of miniaturization of the connector Become. Also, diamond
Operating section C ₁ Le rotating lever C is in contact with the female connector A
In the state, the driven pin 6 'on the female connector A side is driven.
The drive cam groove 2 is located at the entrance 2a 'of the cam groove 2'.
Since the entrance 2a of the hole coincides with the notch 4 for pin guide,
The initial position of the ear rotation lever C can be easily set.
