Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention The present invention relates to a pull-out locking structure for a plug-in connector used for electrical connection of electronic equipment.

BACKGROUND OF THE INVENTION Plug-in connectors are used in prior art electronic and electronic equipment for electrical connections. That is, multiple cables are connected to the housing on one side (e.g., the "male side") of the connector, and when this housing is inserted into the housing on the other side (e.g., the "female side"), electrical It is used for making physical connections.

In conventional connectors, a pull-out locking structure as shown in FIGS. 1 to 3 has been used in order to disconnect the connection in the entire male housing described above. In this connector, a large number of cables 1 are connected to a 21 housing 2 on the male side, and each of the cables 1 and a plug portion 7 are electrically connected. The male housing 2 has a printed circuit board 6
It is inserted into the female side housing 3 which is connected to the female side housing 3. A handle 6 having a claw portion 12 and a pusher 6' is provided at both ends of the female housing 3 so as to be rotatable about the shaft 4.

In a conventional connector having such a structure, when the male housing 2 is completely pulled out, as shown in FIGS. , simultaneously rotate all the handles 6 outward from each other to fully release the lock by the claw portion 12, and push up the male housing 2t with the pusher 6'.
- By pushing up, the male housing 2 was completely removed from the female housing 3.

However, such operation requires two handles 16.6
It is necessary to rotate the connector with both hands at the same time, so there is a problem that the connector cannot be mounted in a narrow space where both hands cannot fit, or it is difficult to move the left and right sides due to the fact that it is difficult to use both hands to rotate the connector. There were various problems, such as the problem of imbalance occurring and damaging the pins of the gauze part 7 (see Fig. 3).

OBJECTS OF THE INVENTION The purpose of the present invention is to provide a connector puller which can solve all of the above-mentioned problems with conventional connectors, which can be operated with one hand, and which can be pulled out and pulled out immediately without damaging the bottle or the like. The objective is to provide a stopping structure.

The above-mentioned object of the present invention is to provide a connector consisting of a pair of removable housings that house electrical connectors, in which the housing on the side to be connected and disconnected has a retainer on the upper part, a pusher and a claw on the lower part. A pair of handles having a pair of handles are rotatably supported so that the pusher and the claw face each other, and when the handles are all rotated outward from each other, the mating housing is fully locked by the claw, and the handle is This is achieved by rotating the two housings inwardly to release the locking by the claw portions, and at the same time, the pusher contacts the mating housing and separates the two housings entirely relative to each other.

Embodiments of the present invention will be described in detail below with reference to all the drawings.

Embodiment of the Invention FIG. 4 is a perspective view showing a connector pull-out locking structure according to an embodiment of the invention. A large number of cables l are connected to the male housing 2 of the connector, and each of the cables l is electrically connected to a plug part. ) is inserted into the side housing 3, similar to conventional connectors.

The feature of this embodiment is that, as shown in detail in FIG.
A pair of handles 6At- are provided. That is, the handle 6A is rotatable about the shaft 4, and has a claw portion 12'ft at its lower end and a pusher 6' above it.

The operation of this embodiment configured as described above will be described below.
This will be explained with reference to FIGS.

When pulling out the male housing 2 from the female housing δ, as shown in FIG. They rotate inwardly, and the claw portion 12 separates from the claw engaging portion 13 of the female housing 3. Around this time, as shown in FIG. 6, the pusher 6 of the handle 6A comes into contact with the female housing 3 and pushes the entire male housing 2 away from the female housing 3, allowing the male housing 2 to be pulled out. can. In addition, as shown in Fig. 7, the handle 6A is attached to the male housing 2, so after pulling out the handle 6A, it is possible to hold the handle 6A without changing the grip.
- The entire male housing 2 can be moved to a predetermined position.

On the other hand, when inserting the male housing 2 into the female housing, the plug part 7 may be inserted into the female housing 3 by the same operation as in the conventional case. After insertion, handle 6A″f
By rotating each other outward, the claw portions 12 engage with the claw retaining portions 13 of the female housing 3, and the male housing 2 is securely locked to the female housing 3.

The above-mentioned operation of rotating the handles 6Ai outward relative to each other can be automatically performed by providing the handles 6m with springs that urge the handles 6Ai to rotate outward relative to each other. This spring is also effective in maintaining the locked state between the male housing 2 and the female housing 3. In addition,
In order to maintain the upper eye self-locking state, a so-called click-stop structure may be used in which the handles 6A' are stopped and maintained there when they are rotated outward from each other.

Furthermore, as shown in FIG. 8, the handle 6 is removed from the center of the housing.
By designing so that the relationship between the distance to the rotation axis of A @l and the separation l from the center of the housing to the engaging part satisfies 10≦l, it is possible to simply connect the cable 1 or Even if the male housing 2 is pulled, the force is applied to the claw portion 12 in the direction of strengthening the engagement, and the locking state 'l@ is maintained, so that the connection of the connector is not released.

In the above embodiment, the handle 6m is connected to the male side housing 2.
However, as shown in FIG. 9, the handle 6m may be provided on the side surface of the male housing 2, and the claw engaging portion 13t may be correspondingly provided on the side surface of the female housing 3. . This makes it possible to reduce the size of the male housing by 2'ft.

Effects of the Invention As described above, according to the present invention, in a connector consisting of a pair of removable housings that house electrical connectors, a retainer is provided on the upper part of the housing on the side that is to be connected and removed. , a pair of handles each having a pusher element and a claw portion at the bottom thereof are rotatably supported so that the pusher element and the claw portion face each other, and by rotating the handles outwardly, The mating housing is fully locked and the handle is rotated inward on all sides to completely release the locking by the claw portion, and the front F pusher comes into contact with the mating housing to relatively separate the two housings. With this structure, it is possible to operate the connector with one hand, and it has the remarkable effect of realizing a pull-out locking structure for the connector that can be pulled out and disconnected in a straight line without damaging the bottle, etc. at the connecting part. .
