Electrical connector and method of fabricating the same

Abstract

This invention provides an electrical connector and its fabrication method. The structure of the electrical connector comprises a metallic element, an insulator shell, and a metallic shell. The metallic element comprises a first spring portion extending lengthwise and a second spring portion extending lengthwise in opposition to the first spring portion. The first spring portion and the second spring portion are connected by a near vertical portion. The insulator shell is a hollow rectangular casing which has a fitting portion. The metallic shell is also a hollow rectangular casing and is used to partially clad the insulator shell. The metallic shell has a flexible first slant portion and a flexible second slant portion which extend into the fitting portion of the insulator shell. When the first spring portion of the metallic element extends into the fitting portion of the insulator shell and forms a gap between it and the bent part of the metallic shell, and the second spring portion of the metallic element extends out of the insulator shell, an electrical connector is formed.
