Abstract

A cable apparatus includes a circuit board having ground and signal pads, an insulating body in front of the circuit board, a pair of differential signal terminals retained in the insulating body, a cable located in front of the insulating body, and a shielding shell fixed to the insulating body. One ground pad is provided on each of two sides of adjacent two signal pads. Each terminal has an elastic portion extending out of the insulating body and conducting the signal pad, and a contacting portion exposed on a surface of the insulating body. The cable has two cable cores connected to the contacting portions, two insulation layers respectively wrapping the cable cores, and a shielding layer wrapping the insulation layers. The shielding shell has one end covering the contacting portions and conducting the shielding layer, and the other end covering the elastic portions and connected to the ground pads.

First claim

What is claimed is:

1. A cable apparatus, comprising:
a circuit board provided with a plurality of ground pads and signal pads, wherein one of the ground pads is provided on each of two sides of adjacent two of the signal pads;
an insulating body located in front of the circuit board;
at least one pair of differential signal terminals retained in the insulating body, wherein one end of each terminal of the at least one pair of differential signal terminals is provided with an elastic portion that extends out of the insulating body and conducts with one of the signal pads, and the other end of each terminal of the at least one pair of differential signal terminals is provided with a contacting portion exposed on a surface of the insulating body;
a cable located in front of the insulating body, wherein the cable comprises two cable cores each being connected to corresponding one of the contacting portions, two insulation layers respectively wrapping the two cable cores, and one shielding layer wrapping the two insulation layers; and
at least one shielding shell fixed to the insulating body, wherein one end of the at least one shielding shell is covered on the contacting portions and conducts with the shielding layer, and the other end of the at least one shielding shell is covered on the elastic portions and is connected to one of the ground pads.

2. The cable apparatus of claim 1 , wherein only two of the signal pads are provided between any adjacent two of the ground pads on a same surface of the circuit board.

3. The cable apparatus of claim 1 ,
wherein the at least one shielding shell has a top wall and two side walls bending and extending from opposite two sides of the top wall;
wherein one end of the top wall is soldered to the shielding layer, and an edge of the other end bends and extends to form a rear wall; and
wherein the rear wall is conductively connected to the one of the ground pads, and an edge of each of the side walls extends to form a shrapnel to urge against the one of the ground pads.

4. The cable apparatus of claim 3 , wherein a location where the shrapnel urges against the one of the ground pads is a first contact location, a location where the elastic portion urges against the one of the signal pads is a second contacting portion, and the first contact location and the second contact location are arranged in a row.

5. The cable apparatus of claim 3 , wherein the shrapnel comprises a connecting portion formed by extending backward from the side wall toward the circuit board, and a guiding portion formed by further extending toward a direction away from the circuit board, the guiding portion urges against the one of the ground pads, and there is a gap between the guiding portion and the side wall.

6. The cable apparatus of claim 5 , wherein an included angle between the guiding portion and the connecting portion is an obtuse angle to make the shrapnel have a shape of a hook.

7. The cable apparatus of claim 3 , wherein the opposite two sides of the top wall further bend and extend to form two extending portions, each of the extending portions is located between the rear wall and corresponding one of the side walls, an edge of each of the extending portions is closer to the circuit board than the edge of corresponding one of the side walls, and does not contact the circuit board.

8. The cable apparatus of claim 7 , wherein the extending portions are not connected to the rear wall.

9. The cable apparatus of claim 1 , wherein the shielding layer is a copper foil, and the shielding layer longitudinally wraps the two insulation layers at the same time along a direction parallel to an axis of the cable core.

10. The cable apparatus of claim 1 ,
wherein each of the ground pads is located on an upper surface or a lower surface of the circuit board, the at least one shielding shell comprises a plurality of shielding shells, each of the ground pads is connected to one of the shielding shells; and
two of the ground pads aligned in a vertical direction are connected through at least two conductive paths, and the two conductive paths are located between two of the shielding shells.

11. The cable apparatus of claim 10 , wherein at least one of the two conductive paths directly faces a location where corresponding one of the shielding shells contacts the ground pad.

12. The cable apparatus of claim 10 , wherein each of the shielding shells has two side walls, an edge of each of the side walls tears and extends to form a shrapnel to urge against corresponding one of the ground pads, one of the conductive paths directly faces a location where the shrapnel contacts the corresponding one of the ground pads.

13. The cable apparatus of claim 1 ,
wherein the insulating body comprises a first body and a second body buckled with the first body;
wherein the at least one pair of differential signal terminals comprises an upper row and a lower row of differential signal terminals that are symmetrically arranged, the upper row and the lower row of the differential signal terminals are respectively integrally formed on the first body and the second body; and
wherein the differential signal terminals in the upper row have the contacting portions exposed on a surface of the first body and soldered to the cable cores, and the differential signal terminals in the lower row have the contacting portions exposed on a surface of the second body and soldered to the cable cores.

14. The cable apparatus of claim 13 , further comprising two plastic blocks respectively covered on the contacting portions of the upper row of the differential signal terminals and the contacting portions of the lower row of the differential signal terminals, wherein the two plastic blocks are integrally formed with the insulating body and the shielding shell.

15. The cable apparatus of claim 1 , wherein the shielding shell is connected to the shielding layer by soldering.

16. The cable apparatus of claim 1 , wherein two adjacent shielding shells and two pairs of the differential signal terminals are provided on a same surface of the circuit board, each of the shielding shells is correspondingly covered on one pair of the differential signal terminals, and adjacent side walls of the two shielding shells are attached to each other and are connected to a same one of the ground pads.
