Even if it is not clearly understood, the fitting work between the housing parts can be easily performed, and the excessive twist of the electric wire W can be prevented.
- the rotation rail portions 13a and 13b are provided in the third housing portion 6 and the rotation suppression lock portions 11a and 11b are provided in the first housing portion 4, but conversely, the rotation suppression lock is provided in the third housing portion.
- a rotation rail part may be provided in the first housing part.
- the rotation base rail portion 13 is provided in the third housing portion 6 and the rotation guide portion 11 is provided in the first housing portion 4. Conversely, the rotation guide portion is provided in the third housing portion, and You may provide a rotation base rail part in 1 housing part.
- the guide rib 16 is provided in the first housing part 4 of the wire harness side connector 2 and the guide rail surface 19a is provided in the second housing part 19 of the sensor side connector 3, but conversely, the wire harness side connector is provided.
- a guide rail surface may be provided on the first housing portion, and a guide rail surface may be provided on the second housing portion of the sensor-side connector.
- the connector device 1 integrally includes a combustion pressure sensor element (not shown) and is attached to the cylinder head 21 of the engine 20, but the present invention is not limited to this.
- the connector device of the present invention can be applied, for example, with or without a sensor element, and it is needless to say that an apparatus having components other than the sensor element as an integral part can also be applied.
- the connector device of the present invention is effective when the mating housing part is not clearly seen by visual observation, but can be used even when the mating housing part is visible. That is, the fitting operation can be easily performed without considering the direction (rotational position) of the counterpart housing portion.
- the rotation prevention part prevents the rotation between the first housing part and the third housing part, and the first housing part and the third housing part. Since the gap does not rotate, rotation before connector fitting can be prevented.
- the rotation guide part guides the rotation between the first housing part and the third housing part, and the first housing part and the third housing part rotate. The connector fitting operation can be performed. Thereby, since rotation other than connector fitting operation
