Receptacle connector

摘要

A receptacle connector, for being inserted by a plug connector and contacted with a casing of the plug connector, includes a housing, a plurality of elastic pieces and a plurality of auxiliary fastening members. The housing includes a plurality of first surfaces and a plurality of second surfaces. The second surfaces are connected to two ends of the first surfaces so as to form an inserting window. The elastic pieces are disposed on the first surfaces. The auxiliary fastening members are disposed on the first surfaces. Each auxiliary fastening member includes a contacting portion formed extendedly at an inner side of the inserting window. When the contacting portions connected with the casing, the contact area between the casing and the auxiliary fastening members can be increased by the contacting portions so as to reduce the contact impedance or resistance between the plug connector and the receptacle connector.

主权项

1. A receptacle connector for being-in contact with a metal shell of a plug connector when the plug connector is inserted into the receptacle connector, comprising:
a metal shell comprising: a plurality of first surfaces including an upper surface and a bottom surface; and a plurality of second surfaces including a right surface and a left surface, which are connected to two ends of the first surfaces so as to form an inserting window; a plurality of elastic pieces disposed on the first surfaces; and a plurality of auxiliary fastening members disposed on at least two corners of the first surfaces and near the inserting window, each of the auxiliary fastening members includes a contacting portion formed by extruding an inner face of the first surface toward an inner space of the metal shell of the receptacle connector, and the two ends of the contacting portion connected to the first surface; wherein when the contacting portions are in contact with the metal shell of the plug connector, the contact area between the metal shell of the plug connector and the auxiliary fastening members are increased by the contacting portions so as to reduce the electrical impedance between the metal shell of the plug connector and the metal shell of the receptacle connector.
