Abstract

A locking device of an electrical connector, wherein the electrical connector comprises an insulating housing, a terminal set and a shielding shell. The insulating housing has at least a sidewall thereby confining at least a containing space between the shielding shell and the sidewall. The locking device can be pivotally connected in the containing space by a pivot and be able to swivel with the pivot. The locking device comprises a main body, a locking portion, a spring arm and an operating portion. The main body has a pivot passing through the central part. The locking portion and the operating portion are respectively at the both ends of the main body. The spring arm, bent from the main body, exerts a pre-loading force toward the sidewall of the insulating housing to keep the locking portion of the locking device in a stationary position.

Claims

1. A locking device of an electrical connector, wherein the electrical connector has a terminal set inserted in an insulating housing, covered with a shielding shell, has at least a sidewall thereby confining at least a containing space between the sidewall and the shielding shell for accommodating the locking device, wherein the locking device comprises:

a main body, pivotally connected within the containing space by a pivot for being swiveled in the containing space;

a locking portion, at an end of the main body for locking on a coupled electrical device;

a spring arm, bent from the main body with the shape of crooks, wherein the spring arm provides for pressing toward the sidewall of the containing space; and

an operating portion, at the other end of the main body away from the locking portion, whereby pushing the operating portion swivels the main body with the pivot as center.

2. The locking device of claim 1, wherein the locking device is cut from a metal plate and the spring arm is bent perpendicularly from the main body of the locking device.

3. The locking device of claim 2, wherein the spring arm of the locking device has at least a U-shaped crooked portion bent from the main body.

4. The locking device of claim 1, wherein the sidewall is bent from the shielding shell.

5. The locking device of claim 1, wherein the spring arm of the locking device exerts a pre-loading force toward the sidewall of the containing space for keeping the locking portion of the locking device in a stationary position.
