High current floating connecting structure

Abstract

A high-current floating connection structure includes a plastic housing, a conductive elastic terminal, and a male pin. The plastic housing has a first opening to define a floating space. The conductive elastic terminal has a fixing portion, a first main body portion, and two opposing second main body portions. The fixing portion of the conductive elastic terminal abuts against a fixing area of ​​the plastic housing to secure the conductive elastic terminal to the plastic housing. The first main body portion is disposed on one side of the two second main body portions, and the first main body portion and the second main body portions are connected to the connecting section of the conductive elastic terminal. The male pin has a short side and a long side and is used to insert into the plastic housing to contact the conductive elastic terminal, such that the male pin can move along a first direction and / or a second direction perpendicular to the first direction through the floating space of the plastic housing.
