Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a connector used for connecting circuits in, for example, automobile wire harnesses.

"Conventional technology" Conventionally, as an example of a connector, Utility Model No. 59-36589
There is something described in the No. As shown in FIG. 3, a stopper 3 is provided on the upper wall 2 of a cylindrical female connector 1, and a stopper 3 is provided on the upper wall 5 of a cylindrical male connector 4.
A band-shaped locking arm 6 is provided in a cantilevered manner so as to be elastically deformable.
When the male connector 4 is inserted into the female connector 1, the locking arm 6 is elastically deformed, the locking projection 7 passes under the stopper 3, and the locking arm 6 is released. When the connector is restored upward, the locking protrusion 7 is caught on the stopper 3, and the male connector 4 can be locked onto the female connector 1.

``Problems to be Solved by the Invention'' However, with such a conventional connector 4, it is difficult to tell whether or not the male and female connectors are locked when the male connector 4 is inserted into the female connector 1. Since the male connector was not fully inserted into the female connector 1, the locking protrusion 7 was not securely engaged with the stopper 3, and the male connector 4 was at risk of slipping out from the female connector 1.

Therefore, conventionally, in order to generate a sound and increase reliability when the male connector 4 is fitted into the female connector 1 and locked, the materials of the female connector 1 and the male connector 4 are made to have high hardness, and the locking protrusion 7 is made of a material with high hardness. The height of the locking arm 6 was increased and the rigidity of the locking arm 6 was increased. However, with these methods, there is a problem in that the fitting force of the male connector 4 to the female connector 1 has to be increased, and the generated noise cannot be obtained even though the fitting force is increased.

An object of the present invention is to provide a connector that solves the above-mentioned problems of conventional connectors.

"Means for Solving the Problems" The present invention has the following configuration in order to achieve the above object. That is, a female housing, a stopper formed on the opening edge of the outer wall of the female housing toward the inside of the opening, and a resonant vibrating piece formed by cutting out the vicinity of the stopper, which can be freely fitted into and removed from the female housing. a male housing formed on the male housing; and an engagement protrusion formed on the male housing and provided on the stopper so as to face the stopper and to be able to freely engage and detach from the stopper when the male housing is fitted into the female housing. an elastic piece that is displaced by contact with the resonant vibrating piece, and is restored when the engaging protrusion passes the stopper and strikes the stopper to vibrate the resonant vibrating piece; The lock release member is configured to release the engagement between the stopper and the engagement protrusion.

"Operation" When the male housing is inserted into the female housing, when the engagement protrusion comes into contact with the stopper, the elastic piece is displaced.
When the engagement protrusion passes the stopper, the elastic piece restores itself and strikes the stopper, causing the resonant vibrating piece to vibrate and produce sound, and the engagement protrusion engages with the stopper to securely fit the male housing into the female housing. Lock.

When the resonant vibrating piece makes a sound, the operator who hears this sound can reliably recognize that the male connector is in the mated state within the female connector. The fitting operation can be ensured.

In other words, the connector of the present invention does not make the worker aware of the completion of the mating work of the male connector to the female connector by making a passive sound that is difficult for the worker to hear. In this way, it is possible to notify the operator by a positive vibration sound made by resonantly vibrating a resonant vibrating piece without particularly increasing the sound pressure.
