Automotive electrical connectors

Abstract

An automotive electrical connector includes a die-cast rear conductor; a stamped hollow front conductor, which is fitted, for example, snap-fitted into a connecting section of the rear conductor; and a plastic injection-molded inner core, which is fitted, for example, snap-fitted into the front conductor and inserted into the connecting section. The rear conductor, front conductor, and inner core, when assembled, provide a cable for insertion and fixation for grounding and signal transmission. The rear conductor exhibits varying wall thicknesses, which not only optimizes high-frequency performance but also provides complete shielding due to its fully enclosed structure, reducing electromagnetic interference and signal leakage during signal transmission and improving electromagnetic compatibility (EMC) performance of high-frequency signals.

Claims

1. An automotive electrical connector, comprising: A conductor formed by die casting has varying wall thicknesses to form a fully enclosed structure, and sequentially forms a tail section, a neck section, and a connecting section; wherein the tail section has a receiving hole for inserting a cable, wherein the cable includes two conductive cores located in the central part, and the free ends of the pair of conductive cores are each coupled to a terminal for signal transmission, and a mesh conductor covered by an outer sheath, the front section of the mesh conductor forming a reverse fold section grounded with the receiving hole; the neck section is for the pair of conductive cores to pass through; and the top surface of the connecting section has a tenon protruding, and an axially formed core chamber communicating with the neck section; a hollow front conductor formed by stamping is fitted onto the connecting section and has an axially formed through groove, the top surface of a rear section of the front conductor has interlocking grooves corresponding to the tenon position, and the bottom surface of the rear section extends backward obliquely with an elastic baffle; And a plastic injection-molded inner core, which is fitted into the through groove and inserted into the core chamber, and has a pair of terminal slots axially opened for the insertion and positioning of the terminals, and a stop wall with a groove and interlocking with each other is opened on at least one surface of the inner core corresponding to the elastic baffle, so that the contact surface between the elastic baffle and the rear conductor can generate a continuous positive force.

2. The automotive electrical connector as described in claim 1, wherein the neck forms a groove for each of the conductive cores to pass through.

3. The automotive electrical connector as described in claim 1, wherein the rear end of the connector segment is provided with a flange for the front conductor to abut against.

4. The automotive electrical connector as described in claim 1, wherein at least one first spring extending forward and / or at least one second spring extending backward are provided in a plurality of hollowed-out grooves circumferentially disposed on the outer peripheral surface of a front section of the front conductor.

5. The automotive electrical connector as described in claim 1, wherein the at least one surface of the inner core includes a top surface and a bottom surface, and the groove and the stop wall are symmetrically provided on the surfaces.

6. The automotive electrical connector as described in claim 1, wherein the front end of the inner core forms a guide ring.

7. The automotive electrical connector as described in claim 1, wherein after the rear conductor and the front conductor are snap-fitted together, they are fixed at the joint of the front conductor by laser spot welding.
