Abstract

A cable connector includes a metal housing, conductive terminals, and contact members. The metal housing includes a first end and a second end opposite to the first end. An accommodation space is formed for communicating with the first end and the second end. The conductive terminals are configured to clamp cables, and each conductive terminal includes a clamp portion, a containing portion, and an engaging portion. The clamp portion and the engaging portion are disposed at two ends of the containing portion, respectively. At least one slot is formed on the engaging portion. Each contact member passes through the accommodation space from the first end and is inserted into the engaging portion. An outside surface of the contact member contacts an inner surface of the engaging portion by making surface-to-surface contact, thereby reducing a resistance value to permit efficient power transmission.

Claims

1. A cable connector, adapted for connecting a cable, the cable connector comprising:

a metal housing having a first end and a second end opposite to the first end, an accommodation space being formed for communicating with the first end and the second end;

at least one conductive terminal for clamping the cable, the conductive terminal having a containing portion and an engaging portion, the engaging portion being directly in contact with one end of the containing portion, wherein at least one slot is formed on the engaging portion;

at least one contact member, passing through the accommodation space from the first end and inserted into the engaging portion, wherein at least a portion of an outside surface of the contact member is in surface-to-surface contact with an inner surface of the engaging portion; and

a wire-fixing block received in the second end, wherein the containing portion is partially disposed inside the wire-fixing block, and the engaging portion is fully disposed outside of the wire-fixing block.

2. The cable connector of claim 1, wherein the conductive terminal further includes a clamp portion and an enclosing portion connected to the clamp portion,

wherein the clamp portion is disposed at the other end of the containing portion opposite to the engaging portion and is partially disposed inside the wire-fixing block, and

the enclosing portion includes two extension arms for fastening a cable core of the cable.

3. The cable connector of claim 1, wherein a diameter of the containing portion is greater than or equal to a diameter of the engaging portion, and at least one protrusion protrudes from a surface of the clamp portion.

4. The cable connector of claim 1, wherein a foolproof portion is disposed on an outer surface of the first end.

5. The cable connector of claim 1, wherein the containing portion and the engaging portion are circular, and the contact member is of cylindrical shape.

6. The cable connector of claim 1, wherein the each of two sides of the wire-fixing block includes a plurality of barriers, a positioning trench is formed between two adjacent barriers for positioning the conductive terminal.

7. The cable connector of claim 6, further comprising an insulation covering, wherein the insulation covering includes a bottom, and the second end and the wire-fixing block are in contact with the bottom.

8. The cable connector of claim 6, wherein the metal housing includes a stop wall therein, and the cable connector further comprising:

a waterproof washer disposed adjacent to the wire-fixing block and in contact against the stop wall, the waterproof washer being provided with at least one through hole, the conductive terminal passing through the through hole.

9. The cable connector of claim 8, wherein the second end includes an engagement hole, and an end face of at least one of the barriers is disposed with an engagement point for engaged with the engagement hole.

10. The cable connector of claim 8, wherein the containing portion further includes at least one pair of barb portions and bumps, the waterproof washer is in contact with one end of the barb portion, and the wire-fixing block is disposed between the waterproof washer and the bottom.

11. The cable connector of claim 1, wherein at least one of the contact members further includes a root portion, the root portion is inserted in the engaging portion, and at least one of the contact members protrudes out of the metal housing from the first end.

12. The cable connector of claim 11, wherein a diameter of the root portion is greater than or equal to a diameter of the engaging portion.

13. A cable connector, adapted for connecting a cable, the cable connector comprising:

a metal housing having a first end and a second end opposite to the first end, an accommodation space being formed for communicating with the first end and the second end;

at least one conductive terminal for clamping the cable, the conductive terminal having a containing portion and an engaging portion, the engaging portion being disposed at one end of the containing portion respectively, wherein at least one slot is formed on the engaging portion;

at least one contact member, passing through the accommodation space from the first end and inserted into the engaging portion, wherein at least a portion of an outside surface of the contact member is in surface-to-surface contact with an inner surface of the engaging portion;

a wire-fixing block received in the second end, each of two sides of the wire-fixing block including a plurality of barriers, a positioning trench being formed between two adjacent barriers for positioning the conductive terminal, and

an insulation covering, wherein the insulation covering includes a bottom, and the second end and the wire-fixing block are in contact with the bottom.
