Problems solved by technology

However, since the distance between each gold finger is limited by the distance between the matching connecting terminal reeds and the size space of the module, the distance between two adjacent gold fingers is not large.
[0004] During hot plugging, there will be sparking and arcing between the gold fingers and the connecting terminals. Since the distance between two adjacent gold fingers is not large, the sparking and arcing may break through the air between the gold fingers and discharge, resulting in a short circuit. A short circuit may cause damage to the device or affect the working condition

Abstract

The invention discloses a golden finger structure and a power source module with the same. The golden finger structure is used for avoiding the phenomenon that in hot plug, breakdown short circuit occurs between adjacent golden fingers due to striking and arc discharging of golden fingers. The golden finger structure comprises at least two golden fingers which are arranged in an adjacent mode, the distance between front ends of the inserted direction of the two adjacent golden fingers is larger than that between rear ends of the inserted direction, and the distance between the front ends of the inserted direction of the two adjacent golden fingers is larger than that of arc extinguishing.

Description

technical field [0001] The invention relates to the technical field of gold fingers, in particular to a gold finger structure and a power module having the gold finger structure. Background technique [0002] The connecting finger refers to the connecting part between the memory stick and the memory slot, and all signals are transmitted through the connecting finger. Gold fingers are composed of many golden-yellow conductive contacts. Because the surface is gold-plated and the conductive contacts are arranged like fingers, they are called "gold fingers". [0003] At present, due to the limited size and space of power modules with high power and high power density, their input and output connections are usually connected by golden fingers. However, since the distance between each gold finger is limited by the distance between the matching connecting terminal reeds and the size space of the module, the distance between two adjacent gold fingers is not large. [0004] During ...
