Abstract
The invention discloses a two-section type HDMI connector and a manufacturing method thereof. The shielding shell of the two-section type HDMI connector is composed of a shell front end part and a shell rear cover part. The shell front end part is provided with a spacing bulge, a first strip-shaped bulge and a first cambered-surface bulge. The rear end of the shell rear cover part is provided with a cylindrical extension segment. The surface of the shell rear cover part is provided with a second strip-shaped bulge and a second cambered-surface bulge. The shell front end part and the shell rear cover part are integrally molded through the stamping process of complete metal sheets. In this way, the generation of slits is effectively reduced and the shielding function is better achieved. The connection part of the shell front end part is embedded in the front interface part of the shell rear cover part, and the connection part is connected with the front interface part via a buckle connection structure. Therefore, the assembly is simple in operation and the connection is steady in effect. After the shell front end part and the shell rear cover part are connected together, the surfaces of the two parts, except that with a plug-in tongue part, are coated with a copper foil or a tin foil. Since the shell is coated, the shielding effect is further improved. Meanwhile, the leakage of electromagnetic waves is avoided and the resistance of the two-section type HDMI connector to the interference of external signals is improved.
