METHOD FOR MANUFACTURING A LOCKING DEVICE AS WELL AS LOCKING DEVICE FOR AN ELECTRIC CONTACT IN A PLUG-TYPE CONNECTOR

Abstract

In order to interlock an electric contact within an insulating body for a plug-type connector, the invention provides integral clips that are axially spaced apart from one another and on the edges of which the electric contact can be interlocked within a through-opening on the mating side and on the connection side. The invention also proposes a method in which two mould cores that encompass one another and form the through-opening can be removed from the through-opening in opposite directions after the injection-moulding process.

Claims

1. A method for manufacturing a locking device for an electric contact in a through-opening and an adjacent insertion compartment in an insulating body using an injection-moulding tool for a plug-type connector, wherein the through-opening in the insulating body is realized with the aid of two mould cores that partially encompass one another, namely a first mould core and a second mould core that are arranged within the injection-moulding tool forming the housing and can be respectively removed from the through-opening in axially opposite directions after the injection-moulding of the insulating body, wherein the mould cores are shaped such that clips featuring clip-on edges are formed on the two ends of the through-opening.

2. Mould cores for a method for manufacturing a locking device according to claim 1, wherein the first mould core has a roughly oval shape, and in that the second mould core is realized in the form of a U-shaped sleeve that can be pushed on and essentially encompasses the first mould core on three sides.

3. Mould cores for a method for manufacturing a locking device according to claim 1, wherein the mould cores are shaped such that they form slopes on the stopping bow and the locking block.

4. A locking device for an electric contact in a through-opening and an adjacent insertion compartment in an insulating body, wherein the through-opening respectively features clips that protrude into the interior on its two ends,wherein the clips are arranged such that they are offset relative to one another by 180°, andwherein the electric contact can be interlocked within the region of the clips that are axially spaced apart from one another.

5. The locking device according to claim 4, wherein the clips are in the form of a U-shaped stopping bow on the end that serves as the mating side and in the form of a locking block on the end that serves as the connection side.

6. The locking device according to claim 5, wherein the U-shaped stopping bow on the mating side extends from its maximum extension protruding into the interior to the inner wall of the through-opening, namely in a symmetric fashion on both sides and without a transition.

7. The locking device according to claim 5, wherein the U-shaped stopping bow features a clip-on edge.

8. The locking device according to claim 5, wherein the locking block on the connection side is provided with a clip-on edge and arranged in the through-opening on an exposed overhang within the insertion compartment of the insulating body on the connection side.

9. The locking device according to claim 4, wherein the electric contact features a circumferential groove, the edges of which are realized in the form of an undercut.
