## 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

### Claim 1

A method for manufacturing a locking device for an electric contact in a through-opening with two ends, namely a mating side and a connection side, an adjacent insertion compartment in an insulating body of a connector housing using an injection-moulding tool for a plug-type connector,
wherein the through-opening in the insulating body is realized via 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, wherein the two mould cores can be respectively removed from the through-opening in axially opposite directions after the injection-moulding of the insulating body, and wherein the mould cores are shaped such that clips featuring clip-on edges are formed on the two ends of the through-opening,
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 side.

### Claim 2

A method for manufacturing a locking device for an electric contact in a through-opening with two ends, namely a mating side and a connection side, an adjacent insertion compartment in an insulating body of a connector housing using an injection-moulding tool for a plug-type connector,
wherein the through-opening in the insulating body is realized via 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, wherein the two mould cores can be respectively removed from the through-opening in axially opposite directions after the injection-moulding of the insulating body, and wherein the mould cores are shaped such that clips featuring clip-on edges are formed on the two ends of the through-opening,
wherein the mould cores are shaped such that they form slopes on the one end of the through-opening as a stopping bow and on the other end as a locking block.
