Description

Connector {Connector}

The present invention relates to connectors.

Connectors are generally constructed by installing terminals of conductive material in a housing of insulating material. Among such connectors, in a connector for signal transmission, a shield shell made of a conductive material is installed in an inner housing in which a terminal is installed in order to minimize generation of noise. Through the shield shell, an electrical connection with the shield shell of the mating connector and the ground structure of the wire is realized.

Such a shield shell may be made to surround the outer surface of the inner housing. However, in general, the inner housing has a cylindrical shape within the outer housing where it is coupled to the mating connector, and the remaining portion has a hexahedral shape. Therefore, the shield shell surrounding the hexahedral portion and the cylindrical portion of the inner housing must be made separately and coupled to each other. In particular, since the metal plates constituting the shield shell meet and are coupled to each other at the corners of the inner housing of the hexahedron-shaped portion, a certain amount of gaps inevitably occur. There is a problem that electromagnetic waves may leak through these gaps.

The shield shell 40 may be electrically connected to the shield of the mating connector and the ground structure of the board.

The shield shell 40 may include a shell body 42 and a tubular portion 56. The shell body 42 may be located on the surface of the inner housing body 22 of the inner housing 20 . The shell body 42 may be composed of a semi-cylindrical portion 43 and a side plate 45. The semi-cylindrical portion 43 may be located on the upper half surface of the inner housing body 22 and the side plate 45 may be located on the surface of the inner cut portion 36 of the inner housing 20.

The center of the semicircle of the cross section of the shell body 42, particularly the semi-cylindrical portion 43, and the center of the cross section of the tubular portion 56 may coincide. Therefore, the shell body 42 of the shield shell 40, in particular, the semi-cylindrical portion 43 and the tubular portion 56 may be concentric. In order to make the semi-cylindrical portion 43 and the tubular portion 56 of the shell body 42 concentric, a portion of the inner housing body 22 is formed in a semi-cylindrical shape.
