Abstract

The invention discloses a power supply connector jack. A contact ring (1) is arranged in a round hole (22) of the jack (2). The contact ring (1) comprises at least two contact chips (10) extending to remote ends. A narrow groove (11) is formed between the contact chips (10). Each of the contact chips (10) is provided with a remote end arc contact region (110) slightly protruding outwardly, and a near end arc contact region (111) slightly retracting inwardly. The tail end of the contact ring (1) connects a plurality of contact chips (10) into a whole through a connecting strip (12). A groove (21) is formed at the front part of the round hole (22). The connecting strip (12) is inserted into the groove (21). The contact ring (1) is a semi-sealing cylindrical structure having an axial opening. The connecting strip (12) and the contact chips (10) are connected through a section of arc transition region (13). The power supply connector jack is capable of meeting the requirements on high density and miniaturization of the power supply connector, can be produced on a large scale, has an excellent practical value, and is reliable in contact and low in cost.

Description

technical field [0001] The invention relates to the technical field of power connectors, in particular to a power connector socket. Background technique [0002] In the interconnection of electronic circuits, the power connector is an indispensable component in the interconnection system of the power circuit, and its quality will directly affect the performance of the entire transmission circuit. [0003] The future development trend of power connectors must be miniaturization and high density. Therefore, how to reduce the contact resistance of the contacts and provide high-reliability contact becomes particularly important in a limited heat dissipation area environment. [0004] In order to improve the current transmission capacity, power connectors generally adopt the method of increasing the heat dissipation area and increasing the thickness of the material, but to meet the requirements of miniaturization and high density, the range of increasing the heat dissipation area...
