Abstract
The present invention basically involves replacing all the mechanical protection (corrugated tube, cover) and sealing (annular seals) parts that are mechanically fitted in electrical connection solutions, in particular for coaxial connection, of the prior art with a joint directly overmolded on the conductive jacket (ferrule, shell or two half-shells), partly inside the connector housing and around the part of the outer sheath of the cable that is near the housing.
Claims14
Electrical connection assembly comprising:
- an electric cable comprising:
- at least one central conductor;
- an electrically insulating outer sheath surrounding the central conductor(s);
- an electrical connector comprising:
- a housing;
- an outer contact (extending along at least one longitudinal axis (X), the outer contact being mounted in the housing;
- at least one central contact extending at least along the longitudinal axis (X), the central contact(s) being mounted inside the outer contact with interpositioning of an electrically insulating body, the central contact(s) being provided with at least one portion that is crimped around the bare free end of the central conductor(s) of the cable;
- an electrically conductive jacket surrounding the inside of the housing, the central contact(s) and the outer contact at least over the length, along the X axis, of the portion that is crimped around the free crimped end of the central conductor(s), by forming a cavity that is practically or fully closed;
- a sealing and mechanical retention joint overmolded both between the jacket and a part of the housing, between the housing part and part of the sheath of the cable, and around said parts.

Method for producing an electrical connection assembly, comprising the following steps:
- a/ supplying an electrical connection assembly comprising:
- an electric cable comprising:
- at least one central conductor;
- an electrically insulating outer sheath surrounding the central conductor(s);
- an electrical connector comprising:
- a housing;
- an outer contact extending along at least one longitudinal axis (X), the outer contact being mounted in the housing;
- at least one central contact extending at least along the longitudinal axis (X), the central contact(s) being mounted inside the outer contact with interpositioning of an electrically insulating body, the central contact(s) being provided with at least one portion that is crimped around the bare free end of the central conductor(s) of the cable;
- an electrically conductive jacket surrounding the inside of the housing, the central contact(s) and the outer contact at least over the length, along the X axis, of the portion that is crimped around the free crimped end of the central conductor(s), by forming a cavity that is practically or fully closed;
- b/ producing an overmold made of at least one polymer material, using a technique called low pressure overmolding, both between the jacket and part of the housing, between the housing part and part of the cable sheath, and around said parts.
