Description

Technical Field

[0001] The utility model relates to the electrical field, in particular to a novel vehicle-mounted HSD connector. Background Art

[0002] In today's society, vehicles require high-quality networks. The HSD connector system is a fully shielded interconnection system that can be used with shielded quad-twisted cables. It is a high-performance digital system for low-voltage differential signals that prevents crosstalk and interference from external sources, so it is widely used in vehicle network connections.

[0003] In the production of HSD connectors, a portion of the shielding layer of the wire needs to be stripped off at the crimping terminal at the end of the cable, resulting in excessively high impedance of the exposed portion of the cable without the outer sheath. Currently, a small gap sleeve is used between the metal parts and the inner sheath of the cable core wire to lock the core wire to reduce the impedance of this portion of the exposed wire. The defects are: first, the distance between the inner sheath of the core wire and the outer conductor is difficult to control, so the size control requirements of the outer conductor are high, which greatly increases the difficulty and cost of the production of the outer conductor, and the assembly is difficult to control; second, the outer conductor is used as a shielding layer, and the outer conductor cannot completely lock the wire, resulting in poor impedance consistency of this section of wire.
