Electric plug and socket assembly
First Claim
1. An electrical plug and socket assembly, comprising:
- an outside part having a barb;
an inside part to be coupled to the outside part, the inside part defining a recess; and
a sleeve positioned on the outside part and arranged to be axially displaced on the outside part, the sleeve having a locked position and an unlocked position, an annular chamber being defined between the sleeve and the outside part, wherein the barb extends into the recess during a coupled state, the barb being secured against a radial deflection by the sleeve in the locked position, the barb having a spring shaft with two spring legs being positioned in a first plane, each of the spring legs supporting a cam, the cams extending radially into a second plane, perpendicular and transverse to the first plane, wherein the inside part has an inside contour for guiding the cams into the recess, the outside part having a first stop for stopping the sleeve in the locked position and a second stop for stopping the sleeve in an unlocked position, the first stop being formed by a retaining collar of the outside part at an insertion opening of the recess, and the sleeve having a sleeve collar that abuts the retaining collar when the sleeve is in the locked position; and
a spring positioned in the annular chamber for restoring the sleeve to the locked position.

Abstract
In order to reliably lock an electric plug and socket assembly (1) including an outer part (2) and inner part (3) which can be coupled to the outer part, the inner part is provided with a recess (17,17′) into which, when the two parts are coupled, a snap-on hook means (14,14′) is engaged and maintained so as to act as a spring. When the plug and socket assembly (1) is in a locked position, the snap-on hook means (14) or each snap-on hook means is locked against radial excursion since it rests on a bushing (7) which is axially displaceable on the outer part (2). In the locked position, the backward pulled bush (7) releases the snap-on hook means (14,14′) thereby allowing for disengagement of the outer and inner parts (2,3). In order to enable the plugging of the parts (2,3) when the bushing (7) is in the locked position, the snap-on hook means (14′) is provided with two spring legs (14c) whose end cam (14′a) and an inner contour (41) running into the recess (17′) of the inner part (3) form a guide for the two leg snap-on hook means (14′).

14. An electrical plug and socket assembly, comprising:
-
an outside part having first and second barbs and having oppositely located openings, the barbs being located in the respective openings;
an inside part to be coupled to the outside part, the inside part defining a recess;
a sleeve positioned on the outside part and arranged to be axially displaced on the outside part, the sleeve having a locked position and an unlocked position;
wherein the barbs extend into the recess during a coupled state, the barbs being secured against a radial deflection by the sleeve in the locked position, the barbs having a spring shaft with two spring legs being positioned in a first plane, each of the spring legs supporting a cam, the cams extending radially into a second plane, perpendicular and transverse to the first plane, wherein the inside part has an inside contour for guiding the cams into the recess, the outside part having a first stop for stopping the sleeve in the locked position and a second stop for stopping the sleeve in an unlocked position, and wherein the inside part and the outside part deviate from a circular shape. - View Dependent Claims (15, 16, 17, 18, 19, 20)
