A lever type connector includes: a first housing; a lever that is rotatably fixed to the first housing; a cam groove formed in the lever; and a second housing having a cam follower. The first housing and the second housing are fitted together by rotating the leverin a fitting direction in a state in which the cam groove and the cam follower are engaged to each other. A plurality of operation protrusions (fitting operating portions) are formed on the lever so as to contact an operator's finger at the time of a fitting operation, and are arranged at an interval in the rotating direction of the lever.

Lever type connector

Areas at outer edge sides of a draw-out area for wires () out of a rear end surface (R) of a housing () serve as operation surfaces () used to push the housing () forward. Areas of the outer periphery of a rear end portion of the housing () corresponding to and before the operation surfaces () are recessed to form outward forming grooves (). The housing () is formed with bores () by further recessing parts of groove bottom surfaces () of the outward facing grooves (). Inward facing projections () engageable with the outward facing grooves () are formed on the inner surface of a wire cover (). Each locking projection () is formed with restricting projections () engageable with the bores ().

Connector

An insulation barrel () of a terminal fitting () is formed with an inclination restricting portion () capable of restricting an inclination of the terminal fitting () in a direction intersecting an axial line direction by contacting an inner wall of a cavity () and a posture correcting portion () inclined with respect to the axial line direction of the terminal fitting () and capable of sliding contact with an opening edge at the rear end of the cavity () in the process of inserting the terminal fitting () into the cavity ().

Terminal fitting with posture correcting edge and inclination restricting portion and a connector provided therewith

A terminal fitting has a base () for receiving a cylindrical sealing plug () mounted on an end of a wire () and crimping pieces (F,R) projecting from opposite lateral edges of the base (). The crimping pieces (F,R) are crimped into connection at different positions of the outer circumferential surface of the sealing plug () in forward and backward directions. The base () is arranged Circumferentially along the lower half of the outer circumferential surface of the sealing plug () from its connected positions with the respective crimping pieces (F,R) and includes receiving portions (F,R) which have lateral edges (E) facing the leading ends of the respective crimping pieces (F,R) in circumferential direction and located at the upper half of the outer circumferential surface of the sealing plug ().

Terminal fitting

A female terminal fitting () is provided with a tubular main portion (), into which a mating male tab () is inserted along an axial center A from the front. A resilient contact piece () extends back in the main portion () and has a free end slidable on an inner surface of the main portion (). The inner surface of the main portion () includes a first slide surface () aligned for permitting displacement of the free end of the resilient contact piece () while maintaining a uniform distance to the axial center (A) of the main portion () and a second slide surface () for permitting displacement of the free end of the resilient contact piece () while increasing the distance to the axial center (A) of the main portion ().

Female terminal fitting

A shielding shell () of a male housing (M) and a shielding shell () of a female housing (F) have the same shape, touching portions () of the shielding shells () are such that outer touching pieces () having contact points at the inner sides and inner touching pieces () having contact points at the outer sides are arranged in circumferential direction, and the inner touching pieces () of one shielding shell () and the outer touching pieces () of the other shielding shell () correspond to and come into contacting with each other in radial directions. Since the shielding shell () of the male housing (M) and that of the female housing (F) have the same shape, cost can be reduced.

Shielded connector and shielding shell

A female housing () is mounted into a male housing () in a direction substantially normal to a connecting direction of the two housings (), and is inserted from this mount position toward the back side of a receptacle along the connecting direction. A moving plate () is assembled inside the receptacle (), has an opening (A) that is open toward a side from which the female housing () is mounted, and is formed with a guiding wall () for positioning the female housing () before the connection is started by being brought into contact with the upper surface and the opposite side surfaces of the female housing () reaching the mount position through the opening (A).
