Abstract: With leverage of a second arm, in a connector locking mechanism that releases a lock of a first arm that corresponds to a locking arm body, a working face of a supporting portion of the second arm is arranged on an upper surface of an upper wall portion of a fitting hood portion of a second connector housing. The fitting hood portion fits with respect to a first connector housing. The working face of the supporting portion of each of a pair of the second arms is arranged so as to be a plane perpendicular to a pressing-down direction of an operating end of each of the second arms.

Abstract: A connector includes: a sensor side connector section mounted to a connector mounting hole and fastened thereto by thread fastening and including a first housing part in which a first terminal is disposed; and a wire harness side connector section disposing a second terminal and including a second housing part capable of being fitted to the first housing part. The connector mounting hole includes a key groove, and the first housing part includes a key protrusion. A bolt prevented from moving axially and supported rotatably is provided on the outer periphery of the first housing part. Screwing the bolt into the connector mounting hole fastens the first housing part to the connector mounting hole by thread fastening.

Abstract: A connector includes: a first connector constituent including a first terminal and a cylindrical part provided with a first locking part and a second locking part; a second connector constituent provided with a second terminal, a first locked part, and a second locked part; and a connector cover body including a first cylindrical part provided with a first abutment part, and a second cylindrical part provided with a second abutment part, the second cylindrical part constituting a locked-part holding part. When the connector cover body is moved closer to the first connector constituent from a state in which the second connector constituent is installed in the connector cover body, the second connector constituent is joined to the first connector constituent.

Abstract: In a connection structure, electric wire includes an inclined sheath section between an exposed core wire section and a whole circumferential sheath section. In the inclined sheath section, an end surface of the insulating sheath on one end side in a longitudinal direction inclines in a direction intersecting the longitudinal direction and thereby a portion of the core wire is exposed. Each of crimping pieces of a terminal has a core wire crimping section that crimps the exposed core wire section, a whole circumferential sheath crimping section that crimps the whole circumferential sheath section, and an inclined sheath crimping section that crimps the inclined sheath section. The terminal is crimped to the electric wire so that the end surface of the inclined sheath section faces a base plate section of the terminal.
