it during handling. The overmolding combines, in this case, three main functions: change of direction, secure fixing, and mechanical protection of the fragile parts.

Extending the life of cable assemblies
The connector-cable transition area is traditionally the weakest point of cable assemblies or harnesses. The basic use of heat-shrink tubing provides a degree of protection of the connections between the wires and the connector contacts but is not always sufficient for links subject to severe operating conditions. Furthermore, the space requirement for heat-shrink sleeves is not always optimized. A cut in the cable or wires quickly leads to a deterioration in the electrical performance of the connection. Overmolding the rear of the connector is the best possible protection. Low bend radii of cables subjected to repeated bending, premature wear due to friction, sealing, or resistance to handling are examples of constraints to be addressed when designing the shapes.
