Description

The present invention relates to an electric wire and a connector for connecting the electric wire and a lighting fixture including the connector.

Conventionally, there are many types of connectors for connecting electric wires, which are placed in a movable state without being fixed in a device in which the connectors are housed. However, in the case of a connector that is placed in a movable state, when vibration is applied to the device in which the connector is housed, the connector may collide with surrounding members, causing abnormal noise or damage to the wire coating. I was afraid. Further, when tension is applied to the electric wire due to vibration, there is a risk that the energized state may become unstable, such as the contact coming out of the connector or the fitting portion of the connector coming off.

Therefore, a connector provided with a fixing device that fixes the connector to the device with a clip and prevents the connector from moving has been proposed. (For example, Patent Document 1.)

Published Utility Model Heisei 1-130277 (Fig. 1)

However, the connector provided with the fixing device described in Patent Document 1 fixes the connector to the panel in a state where the connector is fitted. Therefore, it is necessary to remove the clip (claw) of the connector inserted in the panel every time the instrument connected to the other connector is replaced, and the workability is poor. Also, the clip (claw) is deformed during removal. Therefore, there is a problem that the connector cannot be fixed to the panel and cannot be used again after the device is replaced.

The present invention has been made in view of the above circumstances, and prevents the generation of an abnormal noise and an unstable energized state even when vibration or the like is applied to the device in which the connector is housed, and the mounting workability. It is an object of the present invention to provide an economical connector which is excellent in operation and can be repeatedly used, and a lighting fixture having the connector.

In order to achieve the above object, the present invention has a housing, an insertion opening into which a second connector holding the second wiring is inserted, and a claw extending from the housing, and the insertion opening is a housing. The first opening is provided at a position distant from the bottom surface of the housing and electrically connected to the second wiring while opening at the second surface inclined with respect to the first surface orthogonal to the bottom surface of the body. It is provided with a connector for holding wiring and a lighting fixture having the connector.

According to the present invention, since the claw fixed to the main body unit is provided only on one of the connectors, when removing the connector, the main body unit can be simply removed without removing the claw fixed to the main body unit. The other connector, which is not fixed to the unit, can be removed. Therefore, it is possible to provide an economical connector that can be repeatedly used without the possibility that the claws of the connector will be deformed when the connector is attached or detached.
