Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a connector in which a plug body is fitted into a socket body, and this fitted state can be locked by a locking means.

``Prior Art'' Conventionally, connectors have been used that are provided with locking means for locking the plug body into the socket body.

FIG. 2 shows an example of a conventionally used connector of this kind, and the configuration of the main parts is shown in FIG. The socket main body 11 is formed into a substantially rectangular cylindrical shape, and a fitting opening 13 is formed in one end surface.

Although not shown, a plurality of contact pins are arranged in the socket body 11 in parallel to the axis so as to face the fitting opening 13. These plurality of contact pins are each connected, for example, to a core wire of a cable connected to a connection port provided at an end of the socket body 11 opposite to the fitting port 13.

The plug body 12 is provided with a plug body 15 made of an insulating material, and the socket body 11 of this plug body 15
Insertion holes (not shown) are formed in the protruding end surface 15-P in the insertion direction, and contacts are accommodated in these insertion holes, and one end of these contacts is connected to the end surface 17 facing the protruding end surface of the plug body 12. taken from. A metal shell 20 is attached to the plug body 12 so as to cover the protruding end surface 15-P side of the plug body 12 with its peripheral surface. The metal shell 20 is extended outward at positions facing each other near the end face 17 at right angles to the plate surface of the metal shell 20, and a holding piece 22 is formed in this extended portion.

A metal shell 20 disposed around the plug body 12 from the protruding end surface 15-P side is formed to be similar to the inner circumferential shape of the fitting opening 13 and to be slightly smaller. Lock springs 23 are respectively attached to the holding pieces 22 formed at positions facing each other. The lock spring 23 is formed by bending a metal wire into an annular shape, and both open ends of the annular shape are rotatably attached to the holding piece 22. Further, a gap portion 25 is formed at an annular intermediate position of the lock spring 23 so that the opposing distance is narrowed.

On the other hand, engagement pieces 25-1 and 25-2 are formed on the peripheral surface of the socket body 11 in the vicinity of the fitting opening 13 and extend outward at right angles to the plate surface. An engagement groove 26 is formed between these engagement pieces 25-1, 25-2.
The width of the engagement groove 26 is narrowed in the extending direction of the engagement pieces 25-1 and 25-2 by the end flats 27-1 and 27-2, which are formed by extending the ends of the engagement pieces 25-1 and 27-2 toward each other. ing. On the other hand, the gap between the gap portions 25 of the lock spring 23 is
-2 is formed to be slightly larger than the interval between the two.

The plug body 12 is fitted into the socket body 11 by inserting the protruding portion covered by the metal shell 20 of the plug body 12 into the fitting opening 13 of the socket body 11. By this fitting and mounting, pin contacts (not shown) housed in the socket body 11 are respectively inserted into the insertion holes of the plug body 12. By fitting the socket body 11 and the plug body 12 together in this way,
Pin contacts housed in the socket body connect with contacts mounted on the plug body 12, respectively.

This installed state is locked by a lock means composed of a lock spring 23 and engaging pieces 25-1 and 25-2. That is, with the plug body 12 inserted and fitted into the fitting opening 13 of the socket body 11, the lock spring 23 is rotated to insert the gap portion 25 between the end pieces 27-1 and 27-2. .

Although the gap between the narrow portions 25 is larger than the gap between the end pieces 27-1 and 27-2, when the lock spring 23 is pressed against the engagement groove 26, the lock spring 2
3 moves along the tapers formed on the end pieces 27-1 and 27-2 while being elastically deformed, and the gap between the narrow portions 25 is narrowed and the grooves 3 are inserted into the engagement grooves 26. The gap between the gaps 25 is elastically returned to its original state within the engagement groove 26, and the lock spring 23 does not come out from the engagement groove 26.

In this way, the attachment state of the plug body 12 to the socket body 11 is locked by the locking means. To release the locking means, hold the annular portion of the locking spring 23 and
The lock spring 23 can be pulled out from the engagement groove 26 while being elastically deformed so as to narrow the interval between the lock springs 23 and 5.

``Problems to be solved by the invention'' In the previously used connectors described above, the insertion and fitting operation of the plug body 12 into the socket body 11 and the operation of locking the plug body in this fitted state must be performed separately. No. Therefore, when the lock is locked in the fitted state, after the plug body 12 is inserted and fitted into the socket body 11, the lock spring 23 is newly rotated and the lock spring 23 is inserted into the engagement groove 26. It is necessary to perform an operation to engage it.

Furthermore, a two-step operation is required to release the fitted state between the socket body 11 and the plug body 12. First, attach the lock spring 23 to the gap 2.
While elastically deforming so as to narrow the distance between the sockets 5 and 5, the socket body 11 is moved perpendicularly to the side surface of the socket body 11 in a direction in which it is pulled away from the side surface. By this operation, the engagement between the gap portion 25 and the engagement groove 26 is released, and the lock for fitting and mounting is released. Next, the socket body 1
By pulling out the plug body 12 from the fitting opening 13 of the plug body 1, the fitted state between the socket body 11 and the plug body 12 is released for the first time.

Since the mating operation and the locking operation are performed as separate operations in this way, the series of operations cannot be performed smoothly, and the operability of inserting and removing the socket body and plug body and the locking operation is not good. do not have. The purpose of this invention is to solve the operability problems of conventionally used connectors of this type. The purpose of the present invention is to provide a connector that can improve the performance and smoothly perform these operations through a series of operations.

"Structure of the invention" In this invention, a metal shell is fixedly disposed on the circumferential surface of the plug body on the insertion side with respect to the socket body.
The end of this metal shell opposite to the insertion side end face is located outside the fitting opening when it is fitted with the socket body, and the ends are extended outward at mutually opposing positions to integrally form an extension part. Ru. This extension part has an annular engagement part integrally formed in a part that is cut and raised at a nearly right angle to the insertion direction side of the plug body, and a semicircular A notch is formed. On the other hand, spring bodies are attached to both side edges of the socket body so as to be rotatable around a support shaft on a common plane perpendicular to the insertion/removal direction of the plug body. An engagement piece that elastically engages with the engagement portion is integrally formed at one end of the spring body on the fitting opening side formed in the socket body.
First and second contact pieces are integrally formed at the other end of the spring body, and first and second contact pieces are formed on the socket body to elastically engage with the first and second contact pieces, respectively. A joint is formed.

The spring body is attached to the socket body with the first contact piece being biased and pressure-welded to the first joint part, and the spring body has a common plane between the fulcrum and the other end at right angles to the direction of extension of the spring body. An operating portion is formed in which the spring bodies can be pushed in a direction toward each other. In the state where the engaging portion and the engaging piece are elastically engaged, the first opposing piece is elastically pressed against the first joint portion, and this elastic pressing locks the fitted state between the socket body and the plug body. be done.

When the operation part is pushed in, the elastic pressure contact between the first contact piece and the first joint part is released, and the second contact piece moves into the second contact piece.
It is configured such that it is elastically pressed into contact with the joint portion of the connector, and in this state, the engagement between the engaging portion and the joint piece is released.
