Embodiment Construction

[0021] Preferred embodiments of the present invention are shown below.

[0022] In the connector housing of the present invention, an inclined surface that slides on the inclined surface may be provided at a front end portion of the displacement restricting portion. According to such a structure, since the front end of the displacement restricting portion is less likely to catch on the distal end of the lance, the load applied to the displacement restricting portion and the lance can be further reduced when the terminal fitting is half-inserted.

[0023] Furthermore, in the connector housing of the present invention, a wall surface of the terminal accommodating portion that contacts the detecting portion may be a collision surface substantially perpendicular to the mounting direction of the front holder. According to such a configuration, when there is a terminal fitting in a half-inserted state, since the detection portion collides with the collision surface of the terminal a...

Abstract

The invention provides a connector housing capable of preventing the damage of a spear-shaped member when a terminal fitting is in a semi-inserted state. A front holder (30) is provided with a displacement restricting part (33). When the terminal fitting (10) is correctly inserted, the terminal fitting (10) is inserted into a deflection space (26) from the front part thereof to limit the displacement of the spear-shaped member (23) towards the engagement releasing direction. A detection part (35) detects the existence of the terminal fitting in the semi-inserted state. The front end portion of the spear-shaped member is provided with an inclined surface for preventing the displacement restricting part of the front holder from sliding when in the semi-inserted state. The detection part and the displacement restricting part are integrally formed. When the terminal fitting is correctly inserted, the detection part is accommodated inside the accommodating space (27) of a terminal accommodating part (20). When the terminal fitting is in the semi-inserted state, the displacement restricting part slides to be inclined relative to the inclined surface. at the same time, the detection part is inclined to be in contact with the wall surface of the terminal accommodating part. As a result, the installation action of the front holder is prevented.

Description

technical field [0001] The invention relates to a connector housing. Background technique [0002] Conventionally, a connector housing including a terminal accommodating portion accommodating a terminal fitting and a front holder attached to the terminal accommodating portion from the front is known (for example, described in Patent Document 1 below). The terminal accommodating portion is provided with terminal accommodating chambers each independently accommodating terminal fittings, and each terminal accommodating chamber is provided with a lance that engages with a terminal fitting inserted at a correct position and prevents the terminal fitting from falling off. During the insertion of the terminal fitting, the lance is pressed by the terminal fitting and recedes to the deflection space. If the terminal fitting is inserted correctly, the lance recovers elastically and is locked with the terminal fitting. [0003] The front retainer is provided with a deflection restrict...
