- the first joint part 10, the second joint part 20 and the third joint part 30 attached to the connector part 70 are inserted from one opening part 66 so that the connector part 70 protrudes from the other opening part 64. To place.
- FIG. 13 (c) is a diagram showing a state in which the connector part 70 is attached to the housing body 62.
- the housing body 62 containing the first joint part 10, the second joint part 20, the third joint part 30 and the noise filter 50 is filled with a resin such as epoxy to be molded.
- the joint and noise filter are fixed to the housing 60 and waterproof.
- FIG. 14 is a perspective view schematically showing a state in which the joint part C and the mating connector connected to the wire terminals connected together by the joint part C are fitted.
- the connector 80 is attached to the end of the wire to which the terminal is attached by crimping or the like. By fitting this connector 80 and the connector portion 70 provided in the joint part C, each pin is connected. The terminal 12 and the terminal of each electric wire end are fitted and connected.
- the fitting and locking structure between the connector portion 70 and the connector 80 can be applied to a connector structure that is conventionally used, and therefore will not be described in detail.
- the connector 80 having the terminals connected to the wire terminals derived from the respective devices is simply fitted into the connector part 70 of the joint part C. Times Road connections can be completed.
- the second joint part 20 is Can be connected. Therefore, for example, even when there is a space limitation and a space for arranging the joint parts cannot be secured in the ground lead-out part such as the vehicle body, the second joint part 20 can be grounded.
- the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
- the arrangement of the first joint section, the second joint section, the ground terminals and the noise filter, the number of pin terminals and their arrangement, and the like can be changed as necessary.
- connection of the wire harness becomes easy and the connection workability is improved, and therefore, it can be suitably used for, for example, the wiring connection around the engine of an automobile.
