ABSTRACT:
When a compressed air is led into a reference pressure chamber along with a boundary between a resin housing and a terminal, such compressed air may cause a wire breaking. A barrier wall for blocking the compressed air from penetrating toward the wire is disposed. The reference pressure chamber is divided into a main chamber and a subchamber by the barrier wall. Since the barrier wall blocks the compressed air, the compressed air can not reach a silicon gel in the main chamber. Therefore, the wire breaking caused by the compressed air when connecting a connector therewith can be precluded.
