DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low insertion / extraction force connector used for connection between wire harnesses or connection between a wire harness and electric equipment.

[0002]

2. Description of the Related Art In FIG.
No.), a drive lever c is rotatably provided on a male connector a by a support shaft b, and a driven pin e is protruded from a female connector d.

[0003] Female, arrows male connector a, the initial insertion of d, the driven pin e is positioned into the end of the cam groove c ₁ of the drive lever c (FIG. 5 (A)), the driving lever c from this state female connector d by rotating the marks P direction is drawn by the engagement of the driven pin e cam groove c ₁ (FIG. 5
(B)) The female and male connectors a and d are completely fitted by a leverage of the drive lever c with a low insertion force, and terminal fittings (not shown) accommodated in the female and male connectors a and d. Are connected (FIG. 5C).

The female and male connectors a and d are detached by rotating the drive lever c in a direction opposite to the above, but a greater force is required at the time of detachment than at the time of insertion. That is, at the time of the connector insertion operation, the terminal fitting is connected following the connector insertion operation, so that the insertion movement is performed in the kinetic friction region, whereas at the time of the detaching operation, the terminal fitting is detached from the stationary state of the connector. start be those that withdrawal movement static friction region by, separation force becomes greater than the insertion force, yet is intended to be required maximum withdrawal force during detachment initiation, the
If the disconnection operation is performed for multiple connectors,
This is particularly problematic.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is intended to reduce a detachment force for a plurality of connectors in a low insertion / extraction force connector using a driving member such as a lever.

[0006]

In order to achieve the above-mentioned object, according to the present invention, there are provided a plurality of pairs inserted and removed from each other.
Connector and one of the plurality of connectors are collectively inserted.
And a driving member for entering and leaving operation.
In the number of connector housing chambers, the connector housing chamber and the connector
The drive pin formed on one side of the connector and the
Each connector is supported by the drive member by engagement with the drive slot
At the rear ends of the plurality of driven long holes.
The lengths of the driven long holes are mutually different so that the
A different configuration was adopted.

[0007]

The driving member has a plurality of connectors during the detaching operation.
Starts the detachment operation separately .

[0008]

FIG. 1 shows an electric connection box J connected to a wire harness for an automobile. Two female connectors A are integrally provided on the upper surface of the electric connection box (see FIG. 4). A drive frame C as an insertion / removal drive member is rotatably provided on the female connector A via a rotation fulcrum on one side. That is, a pivot 3 is provided on one side of the drive frame C via the arm 2, and the pivot 3 is rotatably supported by a bearing 4 provided on the electric connection box J. . Therefore, the drive frame C is seated so as to house the female connector A inside from a state of being erected on one side of the female connector A by moving together with the rotation shaft 3 as a fulcrum. An operation unit 5 is provided on the drive frame C on the side opposite to the rotation shaft 3.

In the drive frame C, partition plates 6 and 6 are provided, and two connector accommodating chambers 7 and 7 are formed.
The partition plate 6 and the side plate 8 facing the partition plate 6 are provided with flexible support plates 10 by slits 9, and drive pins 11 are protruded inside each flexible support plate 10 and supported by the drive pins 11. As a result, the male connector B,
B 'is swingably supported. That is, driven elongated holes 12, 12 'extending in the front-rear direction are formed at the rear portions of both side walls of the male connectors B, B', and the driving pins 11 are engaged with the driven elongated holes 12, 12 '. (See FIGS. 3 and 4).
As shown in FIG. 4, the front end portions 12a and 12a 'of the driven elongated holes 12 and 12' are in the same position, but the rear end portions
Are not coincident with each other, and the driven elongated hole 12 'is formed longer. Reference numeral 13 denotes a male terminal accommodated in the female connector A.
A female terminal (not shown) is accommodated in B '.

When the drive frame C is rotated in the direction of the arrow from the state shown in FIG. 1, the male connectors B and B 'are connected to the female connector A.
The drive pin 11 inserts the male connectors B and B 'into the female connector A via the driven elongated holes 12 and 12' (see FIG. 3 (A)). Hole 12,
Since the front ends 12a and 12a 'of 12' coincide with each other,
The male connectors B and B 'are simultaneously completely fitted with the female connector A (see FIGS. 3B and 4A).

When the male connectors B and B 'are disconnected,
After the drive frame C performs a no-load operation due to the play operation of the drive pin 11 due to the driven elongated holes 12 and 12 ′, the drive pin 11 is moved to the rear end of the driven elongated hole 12 by its inertia.
The male connector B is first disengaged by abutting against the engaging portion 12b of the male connector B, and then another drive pin 11 abuts against the engaging portion 12b 'at the rear end of the driven elongated hole 12'. ′ Is disengaged.

[0012]

According to the present invention, as described above, mutual insertion,
A plurality of pairs of connectors to be disconnected;
A drive member that inserts and removes one at a time.
In the plurality of connector accommodating chambers of the driving member,
Driving pin formed on one of the connector housing chamber and the connector
And the driven portion by engagement with a driven elongated hole formed on the other side.
Each connector is supported on the material, and the plurality of driven lengths are provided.
The engagement parts at the rear end of the hole are not aligned with each other.
Since the lengths of the driving slots are different from each other,
Since the detaching operation for the connectors is not started at the same time, the detaching force of the plurality of connectors by the driving member can be reduced and the detaching operation can be facilitated.
