Abstract

An electric connector has a housing, signal and ground contacts disposed in the housing and a metal shell surrounding the housing. The metal shell has a support segment covering a top surface of the housing and with a first edge positioned adjacent to a back surface of the housing, and a second edge positioned adjacent to a front surface of the housing. The ground contacts are formed integral with and extend forwardly from the second edge of the support segment by a one-step stamping process.

Claims

1. An electric connector, comprising:

a housing having a front surface and a back surface;

a plurality of signal contacts disposed in the housing;

a metal shell covering side surfaces of the housing, one segment of the metal shell having a first edge positioned adjacent to the back surface and a second edge positioned adjacent to the front surface; and

a plurality of ground contacts disposed in the housing;

wherein the plurality of ground contacts are formed integral of and extended forwardly from the second edge of said segment, wherein said segment is supported by two corner portions of the metal shell, wherein said segment is depressed with respect to the two corner portions, wherein the housing has a recess formed at a back surface thereof for receiving said segment of the metal shell, wherein said segment is connected to the two corner portions via a respective link portion, wherein the housing further comprising a notch formed at each end portion of the recess for receiving one of the link portion.

2. The electric connector of claim 1, wherein said segment is supported by two corner portions of the metal shell, wherein said segment is within a same plane as the two corner portions.

3. The electric connector as claimed in claim 1, wherein the signal contacts and the grounding contacts are to clamp the counterpart connector.

4. An electric connector, comprising:

a housing, comprising;

a body, comprising a first wall, a second wall opposite to the first wall, and a space formed between the first wall and the second wall for receiving a counterpart connector;

a plurality of upper grooves, formed on a first inner surface of the first wall;

a plurality of lower grooves, formed on a second inner surface of the second wall; and

a recess, formed on an outer rear surface of the housing, wherein the recess is communicating with the space through the upper grooves, and two ends of the recess are respectively formed with a notch penetrating upwardly;

a plurality of signal contacts, disposed in the lower grooves of the housing; and

a metal shell, comprising;

a frame portion, encompassing the housing;

an inwardly deformed portion, integrally connecting the frame portion by means of a bent portion bending downwardly and recessed downwardly with respect to the frame portion, the inwardly deformed portion comprising;

a straight portion embedded in the recess of the housing; and

a plurality of grounding contacts extending from the straight portion and inserting into the upper grooves.

5. The electric connector as claimed in claim 4, wherein each of the grounding contacts comprises:

a contact portion, for contacting the counterpart connector to achieve grounding; and

a spring portion, coupled to the contact portion for urging the contact portion against the counterpart connector.

6. The electric connector as claimed in claim 5, wherein the contact portion is V-shaped.

7. The electric connector as claimed in claim 5, wherein the contact portion is semicircular.

8. The electric connector as claimed in claim 4, wherein the metal shell further comprises at least one folding portion extending from the frame portion and folded inwardly into the frame portion to engage to at least one side wall of the housing.

9. The electric connector as claimed in claim 4, wherein the housing further comprises a plurality of holes and the metal shell further comprising a plurality of tabs each for being received in a hole to fix the metal shell and the housing together.

10. The electric connector as claimed in claim 4, wherein the metal shell further comprises a plurality of second protruding tabs for fixing the connector onto a circuit board.
