Abstract

A cable connector assembly includes an electric connector having an insulating body, a first terminal group, a second terminal group, a latch member, and a first metal shell; and a second metal shell partially wrapping the periphery of a first metal shell. The first and second terminal groups have first and second ground terminals. The latch member is arranged in the insulating body and located between the first and second terminal groups. The latch member has a backward elastic arm partially protruding out of the insulating body. Both the first and second ground terminals are in electric contact with the latch member. The second metal shell has a cable-clamping portion for fixing a cable. The elastic arm elastically urges against the second metal shell.

First claim

What is claimed is:

1. A cable connector assembly for being plugged in a receptacle connector, comprising:
an electrical connector, comprising:
an insulating body;
a first terminal group and a second terminal group respectively received in the insulating body and arranged in an upper row and a lower row, wherein the first terminal group comprises at least one first ground terminal, and the second terminal group comprises at least one second ground terminal;
a latch member disposed in the insulating body and located between the first terminal group and the second terminal group, wherein the latch member comprises a pair of latch arms extending forward and received in the insulating body and at least one elastic arm extending backward and partially protruding out of the insulating body, the latch arms are configured to latch the receptacle connector, and both the at least one first ground terminal and the at least one second ground terminal are in electrical contact with the latch member; and
a first metal shell wrapping a periphery of the insulating body, wherein the elastic arm protrudes backward out of the first metal shell;

a cable for electrical contacting with the first terminal group and the second terminal group; and
a second metal shell, partially wrapping the periphery of the first metal shell and comprising a cable-clamping portion for fixing the cable, wherein the at least one elastic arm elastically urges against the second metal shell.

2. The cable connector assembly of claim 1 , wherein the at least one elastic arm comprises two elastic arms, each of the two elastic arms is formed by deflecting outward from a rear end of corresponding one of the latch arms and extending backward, and a spacing between the two elastic arms is larger than a spacing between the two latch arms.

3. The cable connector assembly of claim 1 , wherein the at least one first ground terminal and the at least one second ground terminal are located respectively on upper and lower sides of the at least one elastic arm to be in electrical contact with a front section of the at least one elastic arm, a rear section of the at least one elastic arm is provided with a conducting portion protruding toward a sidewall of the second metal shell, and the conducting portion elastically urges against the second metal shell.

4. The cable connector assembly of claim 1 , wherein an elastic portion extends integrally from a rear end of the at least one first ground terminal or a rear end of the at least one second ground terminal, and protrudes out of a rear end of the insulating body, and the elastic portion is located at a front side of the at least one elastic arm to elastically urge against the second metal shell.

5. The cable connector assembly of claim 1 , wherein the first terminal group and an upper insulating block are insert-molded as a whole, the second terminal group and a lower insulating block are insert-molded as a whole, a rear end of the insulating body is recessed forward with an accommodating cavity, the upper insulating block and the lower insulating block are installed into the accommodating cavity after being assembled together, a placement platform protruding out of a rear end of the accommodating cavity is formed, the cable is arranged on upper and lower surfaces of the placement platform in order to be soldered to the first terminal group and the second terminal group, and the at least one elastic arm protrudes out of a rear end of the placement platform for elastically urging against the second metal shell.

6. The cable connector assembly of claim 5 , wherein the placement platform is provided with at least one open slot along a direction from the rear end of the placement platform to a front end of the placement platform, the first terminal group comprises at least one first power terminal, the first power terminal has a first soldering surface exposed to the open slot, the second terminal group comprises at least one second power terminal, the second power terminal has a second soldering surface exposed to the open slot, the cable comprises at least one power wire for being inserted into the open slot and located between the first soldering surface and the second soldering surface, such that the power wire is solderable to the first soldering surface and the second soldering surface.

7. The cable connector assembly of claim 1 , wherein a front end of the second metal shell is provided with a first covering portion for wrapping and fixing a rear side of the first metal shell, the second metal shell is provided with a second covering portion for covering the cable, the cable-clamping portion is formed by extending backward from a rear end of the second covering portion, a ground sheet extends integrally from the second metal shell and is located between the first covering portion and the second covering portion, and the ground sheet is in electrical contact with the first ground terminal or the second ground terminal.

8. The cable connector assembly of claim 1 , wherein the cable comprises at least one ground wire, and the at least one ground wire is in electrical contact with at least one of the at least one first ground terminal, the at least one second ground terminal, the latch member and the second metal shell.

9. The cable connector assembly of claim 8 , wherein a sidewall of the second metal shell is provided with a soldering hole, and the ground wire is inserted in the soldering hole in order to be soldered to the second metal shell.

10. The cable connector assembly of claim 9 , wherein the second metal shell comprises an upper shell and a lower shell, both sides of the upper shell are provided with a plurality of fastening portions, both sides of the lower shell are provided with a plurality of fastening holes respectively matching with the plurality of fastening portions, and the soldering hole is located between two neighboring fastening portions.

11. A cable connector assembly for electrically connecting with a receptacle connector, comprising:
an electrical connector, comprising:
an insulating body;
a plurality of signal terminals received in the insulating body for electrically contacting with the receptacle connector;
a ground assembly, received in the insulating body and partially protruding out of a rear end of the insulating body; and
a first metal shell wrapping a periphery of the insulating body;

a second metal shell, partially wrapping a periphery of the first metal shell and comprising a cable-clamping portion, wherein the ground assembly elastically urges against the second metal shell; and
a cable fixed by the cable-clamping portion, wherein the cable comprises a plurality of signal wires and at least one ground wire, the signal wires respectively contact with the signal terminals, and the ground wire is in electrical contact with at least one of the ground assembly and the second metal shell.

12. The cable connector assembly of claim 11 , wherein the ground assembly comprises a first ground terminal and a latch member, a front end of the latch member is provided with a pair of latch arms for latching the receptacle connector, an elastic arm extends backward from each of the latch arms and protrudes out of the rear end of the insulating body, the elastic arms elastically urge against the second metal shell, and the first ground terminal is in electrical contact with at least one of the latch member and the second metal shell.
