Therefore, there is a problem that workability is not good. In addition to the connector's original wire, a wire for mating inspection must be provided, and the extra unnecessary wires for the connector make the connector troublesome and complicated. There is a problem that is.

In view of the above circumstances, an object of the present invention is to be able to immediately know whether or not the mating is good at the time of mating work, reduce the handleability of the connector due to the mating inspection wire, and complicate the wire. It is to provide a connector that solves the above problem.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a connector according to a first aspect of the present invention has a male connector portion and a female connector portion that are fitted to each other, and one of the connector portions has a first locking portion. , A second locking portion is formed on the other side, and when the both connector portions are fitted, the first and second locking portions are locked to each other and are fitted into the locking recess by the locking. In the connector for preventing the disengagement of both connector parts from each other, a first conductor is provided on the first locking part, and the second locking part is locked to the first locking part. At this time, a second conductor is provided in the front part of the fitting direction adjacent to the contact part, excluding the contact part that comes into contact with the first locking part, and either of the first or second conductors is provided. One of the conductors is composed of a pair of separated conductive pieces, and the connector part provided with the pair of conductive pieces is A sound generating circuit connected to the pair of conductive pieces is provided, and in a half-fitted state before the first and second locking portions are locked to each other, the pair of conductive members contact each other to cause the pair of conductive members to contact each other.

[0008]

[Action]

 As described above, in the connector according to the first aspect of the invention, the first conductor is provided in the first locking portion, and the second conductor is provided in the front portion of the second locking portion in the fitting direction. Since the connector is provided with the connector, the first and second locking portions are in a state before they are in a completely fitted state by locking the first and second locking portions, that is, the first locking portion is in the second state. In the semi-fitted state, which is in the front position in the fitting direction adjacent to the locking part, the first and second conductors come into contact with each other and a sound is generated from the sound generation circuit, resulting in a completely fitted state. When that happens, the contact between both conductors is released and the sound stops.

That is, when the connector is engaged, sound is generated in the semi-engaged state, and the sound is stopped when the connector is in the fully engaged state. It is possible to know whether the mating is good or bad without requiring any operation, and workability is improved. In addition, since the sound generation circuit is provided directly on any of the connector sections, and there is no need for an inspection electric wire to connect to an external lamp, etc., the handleability of the connector caused by the extra inspection electric wire It is possible to prevent a decrease in power consumption and a complicated electric wire.

Further, in the connector according to the second aspect of the present invention, since the electric conductor is provided on the first and second locking portions as described above, the first locking is achieved when the both connector portions are fitted together. When the part and the second locking part are locked to each other and are in a completely fitted state, both conductors come into contact with each other, and sound is generated from the sound generation circuit. Therefore, also in this case, similarly to the connector according to the first aspect of the present invention, the sound is generated, so that it is possible to know the quality of the fitting at the time of the fitting work and without requiring any additional operation, thereby improving the workability. In addition, since the inspection electric wire connected to an external lamp or the like is unnecessary, it is possible to prevent the handling of the connector from being deteriorated and the electric wire from being complicated due to the electric wire.

Further, since the connector according to the second aspect of the present invention produces a sound only when it is in a completely mated state, it is necessary for an operator to check the sound of all the mating connectors. If it sounds for only a short time, it is difficult to verify it after the work, and when mating two or more connectors, it may cause an illusion that the worker heard the sound. However, in contrast, the connector according to the first invention continues to emit a sound in the half-fitted state until it is completely mated, so even if the connector flows through the line as it is in the half-fitted state, In the next step, another worker notices it, so that the half-fitting prevention is more reliable.
