Grounding structure of electrical connectors

Abstract

This invention relates to a grounding structure for an electrical connector, comprising: an insulating body having a mating space inside; two terminal groups disposed in the mating space, including a plurality of signal terminals and a plurality of ground terminals arranged in an alternating manner, each of the plurality of signal terminals and the plurality of ground terminals having a mating portion bent inward from the top and a soldering portion bent outward from the bottom, and a terminal base being provided between the mating portion and the soldering portion of each of the two terminal groups; and two grounding plates embedded in the two terminal bases, each of the two grounding plates having a main body and a plurality of turning portions extending to one side from the main body, the plurality of turning portions having a soldering surface that is fixed by soldering at the plurality of ground terminals of the two terminal groups, thereby forming a highly stable soldering between the plurality of turning portions of the two grounding plates and the plurality of ground terminals of the two terminal groups.

Claims

1. A grounding structure for an electrical connector, comprising: An insulating body having a mating space inside; two terminal groups installed on opposite sides of the mating space, each terminal group including a plurality of signal terminals and a plurality of ground terminals arranged in an alternating manner, each signal terminal and ground terminal having a mating portion bent inward from above and a welding portion bent outward from below, and a terminal base provided between the mating portion and the welding portion of each terminal group; and two grounding plates embedded in the two terminal bases, each grounding plate having a main body and a plurality of turning portions extending to one side from the main body, the turning portions having a fixed welding surface formed by welding at the grounding terminals of the two terminal groups.

2. The grounding structure of the electrical connector as described in claim 1, wherein both ends of the insulating body are provided with a sliding groove and a positioning groove, the sliding groove and the positioning groove respectively for the guide spring and the positioning spring of a shielding shell to slide and position and hold, so that the shielding shell is fixed to the outside of the insulating body.

3. The grounding structure of the electrical connector as described in claim 2, wherein the shielding housing has a plurality of fixed pins at both ends that can be soldered to an external circuit board.

4. The grounding structure of the electrical connector as described in claim 1, wherein the insulating body is provided with a plurality of latching grooves on both sides for a plurality of latches protruding from the outer surface of the two terminal blocks to be fastened and fixed, and a plurality of limiting grooves are provided on both sides of the insulating body for a plurality of accommodating and supporting the suspended ends of the mating portions of the two terminal blocks.

5. The grounding structure of the electrical connector as described in claim 1, wherein the insulating body has a plurality of positioning posts at both ends downward for insertion and fixing to an external circuit board.

6. The grounding structure of the electrical connector as claimed in claim 1, wherein the two terminal blocks are embedded on opposite outer sides of the two terminal groups by an embedded injection method, and the turning portions of the two ground blocks are welded to the grounding terminals on opposite inner sides.

7. The grounding structure of the electrical connector as described in claim 1, wherein the two terminal blocks are embedded in the opposite inner side of the two terminal blocks by an embedded injection method, and the turning portions of the two ground blocks are welded to the grounding terminals on the opposite outer side.

8. The grounding structure of the electrical connector as described in claim 7, wherein the two terminal blocks are provided with a plurality of staggered protrusions and a plurality of hollowed-out portions on their respective inner sides, a storage space is formed between adjacent protrusions, and a fixing groove is provided in each of the protrusions, while the hollowed-out portions are for the main body of the two grounding plates to be exposed.

9. The grounding structure of the electrical connector as described in claim 8, wherein a conductive plastic is provided between the two terminal blocks, the conductive plastic being composed of a plurality of substrates and fixing posts disposed between adjacent substrates, the fixing posts extending upward into the fixing grooves of the two terminal blocks to form a snap-fit ​​fixation, and the substrate including a top protrusion with a longer vertical length and a bottom protrusion with a shorter vertical length, the top protrusions being located in the receiving spaces of the two terminal blocks, and the side protrusions extending horizontally to both sides of the substrate, the outward contact surfaces of the side protrusions forming hard interference contact with the abutting surfaces of the main bodies of the two grounding plates.

10. The grounding structure of the electrical connector as claimed in claim 1, wherein the bends of the grounding plate and the grounding terminals are fixedly and electrically connected by laser spot welding.
