Optical connector

Housing for optical connector

There is provided a waterproof connector. The waterproof connector comprises a connector member supporting a ferrule to be butted against a target ferrule disposed in a target connector, the connector member being adapted to be locked to an adapter member of the target connector by an action of a lock operation portion provided in the connector member; unlocking means being adapted to operate the lock operation portion to release the locked state; and a housing body allowing the unlocking means to be slidably moved. The waterproof connector is adapted to be released from the connection with the target connector in such a manner that the unlocking means is allowed to be moved away from the connector member, whereby the unlocking means is operable to operate the lock operation portion to release the locked state, and to move the connector member away from the adapter member to release the fitting.

Waterproof connector and waterproof device using the same

A waterproof connector is to be connected to a mating connector, and a waterproof apparatus includes the waterproof connector and the mating connector. The waterproof connector includes a connector member to be connected to an adapter member; a connecting member to be connected to a cylindrical portion of a mating connector; and a main body portion. The connector member is able to slide along a facing direction of the connectors in a given range. The waterproof connector and the waterproof apparatus improve an efficiency of the performance by associating the operations with each other.
