Electrical connector having a pair of metallic shells

摘要

An electrical connector (100) includes an insulative housing (1), a plurality of terminals (2), a metal plate (3), a first metallic shell (4) and a second metallic shell (5). The first metallic shell has a pair of side walls (43). The second metallic shell includes a pair of side boards (52). Each side wall has a first portion (4301), a second portion (4302), an elastic fin (431) extending from the first portion and a first angle relative to the second portion. Each side board defines a window (521) and the elastic fin protrudes into the window and resists against a contour of the window at a plurality of resisting points (4321) for prohibiting a relative movement of the first metallic shell, with respect to the second metallic shell. Each elastic fin is located in a vertical plane and the degree of the first angle is between 0 and 90°.

主权项

1. An electrical connector comprising:
an insulative housing having a base portion; a plurality of terminals retained in the insulative housing; a first metallic shell enclosing the insulative housing and having a pair of opposite side walls, each side wall having a first portion and a second portion; and a second metallic shell covering the first metallic shell and having a top board and a pair of side boards; wherein said side wall having an elastic fin extending from the first portion and located in a vertical plane, said elastic fin forming a first angle between 0 and 90° relative to the second portion; each side board defining a window, said elastic fin protruding into the window and resisting against a contour of the window at a plurality of resisting points for prohibiting a relative movement of the first metallic shell, with the respect to the second metallic shell; wherein each elastic fin is formed with a bulge protruding outwardly through the window and abutting against the contour of the window at a plurality of abutting points for prohibiting a relative movement of the first metallic shell, with the respect to the second metallic shell along a front-to-back direction; each window has a first hole and a second hole located below the first hole, the resisting points are disposed around the first hole, and the abutting points are disposed around the second hole; wherein each bulge has a curved surface, a pair of side surfaces and a bottom surface connecting the curved surface and the side surfaces, and the bottom surface resists against the contour of the second hole.
