Abstract

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.

First claim

What is claimed is:

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.

2. The receptacle connector according to claim 1 , wherein each of the auxiliary fastening members defines an elongating opening disposed between the contacting portion and the first surface.

3. The receptacle connector according to claim 1 , wherein each contacting portion comprises a connecting point, each contacting portion is contacted with the metal shell of the receptacle connector by the connecting point.

4. The receptacle connector according to claim 1 , wherein each contacting portion comprises a connecting line, each contacting portion is contacted with the metal shell of the receptacle connector by the connecting line.

5. The receptacle connector according to claim 1 , wherein each contacting portion comprises a connecting plane, each contacting portion is contacted with the metal shell of the receptacle connector by the connecting plane.

6. The receptacle connector according to claim 1 , wherein the contact areas between the metal shell of the plug connector and the auxiliary fastening members are increased by the contacting portions so as to reduce the contact impedance between the metal shell of the plug connector and the metal shell of the receptacle connector when the contacting portions are in contact with the metal shell of the plug connector.

7. The receptacle connector according to claim 1 , further comprises:
an insulated housing comprising a base portion and a tongue portion protruding beyond the base portion, wherein the tongue portion is extended along a rear-to-front direction and includes a mating face and an opposite face thereof;
a plurality of terminals held in the insulated housing and divided into a first set of terminals and a second set of terminals, wherein a plurality of elastic contact portions of the first set of terminals are located on the mating face in a first position along the rear-to-front direction and a plurality of non-elastic contact portions of the second set of terminals are located on the mating face in a second position along the rear-to-front direction which are different from the first position.

8. The receptacle connector according to claim 1 , wherein each auxiliary fastening member is disposed between the near elastic piece and the near second surface.

9. The receptacle connector according to claim 1 , wherein a first interval is defined between the auxiliary fastening member and the near second surface and a second interval is defined between the auxiliary fastening members.

10. A receptacle connector provided for being inserted by a plug connector and contacted with a casing of the plug connector, comprising:
a metal shell comprising:
a plurality of first surfaces; and
a plurality of second surfaces, 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 two sides of the first surfaces, each auxiliary fastening member comprising a contacting portion extendedly formed at an inner side of the inserting window;
wherein when the contacting portions are 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 electrical resistance between the plug connector and the receptacle connector, and
wherein the contacting portion comprises a bending segment and an extending segment, the bending segment is disposed on flange of the inserting window, the extending segment is connected to the bending segments and extended toward the inner side of the inserting window.

11. The receptacle connector according to claim 10 , further comprises:
an insulated housing comprising a base portion and a tongue portion protruding beyond the base portion, wherein the tongue portion is extended along a rear-to-front direction and includes a mating face and an opposite face thereof;
a plurality of terminals held in the insulated housing and divided into a first set of terminals and a second set of terminals, wherein a plurality of elastic contact portions of the first set of terminals are located on the mating face in a first position along the rear-to-front direction and a plurality of non-elastic contact portions of second set of terminals are located on the mating face in a second position along the rear-to-front direction which are different from the first position.

12. 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:
an insulated housing comprising a base portion and a tongue portion protruding beyond the base portion, wherein the tongue portion is extended along a rear-to-front direction and includes a mating face and an opposite face thereof;
a plurality of terminals held in the insulated housing and divided into a first set of terminals and a second set of terminals, wherein a plurality of elastic contact portions of the first set of terminals are located on the mating face in a first position along the rear-to-front direction and a plurality of non-elastic contact portions of the second set of terminals are located on the mating face in a second position along the rear-to-front direction which are different from the first position;
a metal shell, comprising:
a plurality of first surfaces comprising an upper surface and a bottom surface; and
a plurality of second surfaces comprising a right surface and a left surface which are connected to two ends of the upper surface and the bottom surface 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, wherein each of the auxiliary fastening members is disposed between the near first surface and the near elastic pieces and each of the auxiliary fastening members comprises a contacting portion formed toward an inner space of the metal shell of the receptacle connector.

13. The receptacle connector according to claim 12 , wherein the contacting portions are formed by extruding the inner faces of the first surfaces toward the inner space of the metal shell of the receptacle connector, and two ends of the contacting portion connected to the first surface.
