A shield terminal () includes an inner conductor terminal (), dielectrics () configured to accommodate the inner conductor terminal (), an outer conductor terminal () configured to surround the dielectrics (), a tubular fitting () formed in a front end part of the outer conductor terminal () in an axial direction, and resilient contacts () formed in the tubular fitting () and having both front and rear ends integrally connected to the tubular fitting (). The tubular fitting () has interlocking regions () surrounding only front end parts (F) of the resilient contacts () and connected to front ends of the resilient contacts () are radially resiliently deflectable with front end sides thereof as free ends.

Shield terminal and outer conductor terminal

A connector includes a pressure receiving surface () on a front of a locking lance () and a lock () on a terminal () is configured to lock the pressure receiving surface (). An inclined surface () on a facing surface () of the locking lance () faces the terminal () and is inclined to be more separated from the terminal fitting () toward the back. A guiding surface () on the pressure receiving surface () is configured to deflect the locking lance () toward the terminal () when the lock () presses the pressure receiving surface (). A contact surface () behind the pressure receiving surface () on the locking lance () faces the terminal (). A deflection regulating portion () behind the lock () on the terminal () faces the contact surface () while being spaced apart parallel to a resilient deflecting direction of the locking lance ().

A connector (C) includes a housing () formed with terminal accommodation chambers (). Terminal fittings () are inserted into the terminal accommodation chambers () from behind. Rectangular tab insertion holes () penetrates through a front wall () of the housing () and allow tabs () to be inserted into the terminal accommodation chambers (). Guide slopes () are formed by recessing and tapering an opening edge part of the tab insertion hole () on a front surface of the front wall (). Detection holes () penetrate through the front wall () and communicate with corner parts of the tab insertion holes () so that a probe () for conduction test can be inserted into the terminal accommodation chambers () from the front.
