Connector with a locking lance

摘要

A locking lance (20) on the inner surface of a cavity (19) of a housing (11) includes a lance main body (21) and an inclined portion (22). The lance main body (21) is cantilevered forward toward the center of the cavity (19) from the inner surface of the cavity (19). The inclined portion (22) is connected to a front part of the lance main body (21) and is narrower than a rear part of the lance main body (21). A first inclined surface (31) of the inclined portion (22) faces the interior of the cavity (19) and inclines away from the center of the cavity (19) to the front. A second inclined surface (32) is opposite the first inclined surface (31), inclines toward the center of the cavity (19) to the front, and is tapered so that the first inclined surface (31) becomes gradually narrower toward the front.

主权项

1. A connector, comprising:
a housing with at least one cavity for receiving a terminal fitting; a lance main body cantilevered forward and toward the center of the cavity from an inner surface of the cavity and configured to interfere with the terminal fitting and deform resiliently during insertion of the terminal fitting into the cavity, the lance main body resiliently returning and retaining the terminal fitting when the terminal fitting is inserted properly in the cavity; an inclined portion connected to a front end part of the lance main body and including first and second inclined surfaces, the first inclined portion being at a position facing the interior of the cavity and inclined farther away from the center of the cavity toward the front, the second inclined surface being at a position substantially adjacent to the first inclined surface and inclined in a direction more toward the center of the cavity to the front and having a tapered shape so that the first inclined surface becomes gradually narrower toward the front; and a recess at a position of the inner surface of the cavity substantially facing the second inclined surface for receiving the inclined portion when the lance main body is resiliently deformed.
