Spring contact finger, socket and socket system

Abstract

The embodiment of the invention discloses a spring contact finger, a socket and a socket system, wherein the spring contact finger comprises a spring wire; the spring wire is spirally coiled along an oblique elliptical track to form a unit ring; and multiple unit rings are bi-directionally spirally coiled along the axial line to form an oblique ellipse spring contact finger. The spring contact finger follows two spiral tracks, the unit ring of the spring contact finger is formed by coiling along the oblique elliptical track, and multiple unit rings are bi-directionally spirally coiled along the axial line track again to form an oblique ellipse bi-directional spring contact finger. When the contact finger receives contact pressure to generate stress and deformation, on the basis of guaranteeing reliable contact and slow stress, because the oblique ellipse bi-directional spring contact finger can provide multiple row-type contact points to combine with the contact points on the oblique ellipse of the unit ring, the number of the contact points between the socket and the spring contact finger are greatly increased, contact temperature rise is effectively reduced, the service life of the spring contact finger and the socket is prolonged, and accident probability is reduced.

Description

technical field [0001] The invention relates to the technical field of electric contact, and more specifically relates to an oblique elliptical two-way spring contact finger, a socket and a socket system. Background technique [0002] A socket is an electrical device that provides a power interface for an electrical appliance, enabling the electrical appliance to be energized or wired. Existing socket contact conductors mostly use arc-shaped punched shrapnel or oblique elliptical spring contacts to form jacks. [0003] Due to the limitation of stamping precision, the circular arc-shaped stamped shrapnel is prone to poor contact between the socket and the plug, and the cross-sectional area of ​​the stamped shrapnel is relatively small, resulting in limited transmission current. [0004] Therefore, the existing arc-shaped stamping shrapnel has unreliable contact when the plug is frequently plugged in and out, and the contact temperature rises when a large current is applied, ...

[0003] The arc-shaped stamping shrapnel is prone to poor contact between the socket and the plug due to the limitation of punching precision, and the cross-sectional area of ​​the stamping shrapnel is relatively small, resulting in limited transmission current

[0004] Therefore, the existing arc-shaped stamping shrapnel has unreliable contact when the plug is frequently plugged in and out, and the contact temperature rises when a large current is applied, which reduces the service life of the spring contact fingers and the socket and increases chance of accident
