Abstract

The invention discloses a contact spring coil in a power connector, which comprises at least two contact sheets (10) extending to a distal end, wherein a narrow groove (11) is formed between the contact sheets (10), each contact sheet (10) is provided with a distal end circular arc contact region (110) protruding outwards slightly and a proximal end circular arc contact region (111) retracting inwards slightly, and a tail end of the contact spring coil (1) connects a plurality of contact sheets (10) into a whole via a connecting strip (12). The contact spring coil (1) is an axially opened semi-closed cylindrical structure. The connecting strip (12) is connected with the contact sheets (10) via a circular arc transition region (13). The contact spring coil (1) is a thin elastic copper alloy formed by punching and circle curling. The contact spring coil is used in a jack of the power connector in order to be reliably connected with a pin in cooperation with the jack, can meet the requirements of the power connector on high density and miniaturization, and is reliable in contact, low in cost, capable of mass production and great in practical value.

Description

technical field

[0001] The invention relates to the technical field of power connectors, in particular to a contact coil in the power connector. 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 dis...
