Connector with a locking and unlocking mechanism

摘要

A connector with a locking and unlocking mechanism is disclosed. The connector includes a case, a spring member and an unlocking member. The case includes a guiding groove, a narrow groove, a protrusion, a vertical stop wall and a latching groove. The spring member and the unlocking member are mounted the case. The unlocking member includes a guiding arm, a latching plate and a bending end. A vertical portion of the unlocking member is inserted between the spring member and the case. The guiding arm extends into the corresponding guiding groove. The latching plate enters into the latching groove. The bending end enters into the narrow groove and covers the protrusion. When a pulling portion is pulled back, the vertical portion compresses the spring member, the latching plate slides back along the latching groove, and the bending end moves back along the protrusion.

主权项

1. A connector with a locking and unlocking mechanism, comprising:
a case including an inserting portion located in the front thereof, a retaining portion located in the rear thereof, and two guiding grooves being symmetrically formed two opposite sides of the case; the retaining portion including a top surface, a mounting surface lower than the top surface, and a shoulder connecting the mounting surface and the top surface; the case further including a narrow groove, which is located in front of each guiding groove and the width of which is less than that of the guiding groove, a protrusion located in the narrow groove, a vertical stop wall located between the guiding groove and the narrow groove, and a latching groove located in rear of the vertical stop wall; a spring member being mounted on the mounting surface and having at least one supporting foot facing the shoulder; and an unlocking member including a top wall, a vertical portion bent downward from a front side of the top wall, two symmetrical guiding arms respectively bent downward from two sides of the top wall and extending forward, and a pulling portion located in rear of the top wall; the unlocking member further including a latching plate, which is formed in front of each of the two guiding arms and the width of which is larger than that of the guiding arm, and a bending end, which extends forward from a front edge of the latching plate and the width of which is less than that of the guiding arm; wherein the top wall of the unlocking member covers the mounting surface, the vertical portion being inserted between the supporting foot and the shoulder, the supporting foot pressing on the vertical portion, the guiding arm extending into the corresponding guiding groove, the latching plate entering into the latching groove, the bending end entering into the narrow groove and covering the protrusion, the length of the latching plate being less than that of the latching groove; when pulling the pulling portion backward, the vertical portion being moved backward and compressing the spring member, the guiding arm being moved backward along the guiding groove, the latching plate sliding backward along the latching groove, and the bending end being moved backward along the protrusion.
