Abstract

A cable connector assembly includes a mating member ( 1 ), a cable ( 300 ) connected with the mating member, a strain relief member ( 4 ) enclosing on the cable and the mating member, a cover ( 6 ) enclosing on the strain relief member, and a retaining member ( 5 ) formed between the strain relief member and the cover. The strain relief member is made of a first type of plastic material, and the retaining member is made of a second type of plastic material, the second type of plastic material being harder than the first type of plastic material.

First claim

What is claimed is:

1. A cable connector assembly comprising:
a mating member;
a cable connected with the mating member;
a strain relief member enclosing on the cable and the mating member and made of a first type of plastic material;
a cover enclosing on the strain relief member; and
a retaining member formed between the strain relief member and the cover and made of a second type of plastic material, the second type of plastic material being harder than the first type of plastic material.

2. The cable connector assembly as recited in claim 1 , wherein the retaining member comprises a ring portion with a closed circumference, a pair of extension portions extending from a back end of the ring portion, and an opening formed by the two extension portions.

3. The cable connector assembly as recited in claim 2 , wherein the mating member has a metal shell, the mating shell comprising a front section for being inserted into a complementary connector and a rear section of a larger size than the front section.

4. The cable connector assembly as recited in claim 3 , wherein the ring portion has a front aperture accommodating the front section of the mating shell and abutting against the rear section of the mating shell.

5. The cable connector assembly as recited in claim 3 , wherein the retaining member is coupled with the strain relief member via glue.

6. The cable connector assembly as recited in claim 5 , wherein each extension portion has a groove exposed to outside for receiving glue when combining the cover with the retaining member.

7. The cable connector assembly as recited in claim 1 , wherein the first type of plastic material is PVC material.

8. The cable connector assembly as recited in claim 1 , wherein the second type of plastic material is ABS material mixed with PC material.

9. A method for manufacturing a cable connector assembly, comprising the steps of:
connecting a mating member with a cable;
enclosing a retaining member on the mating member along a front-to-back direction;
molding a strain relief member in the retaining member and enclosing the strain relief member on the cable and the mating member; and
enclosing a cover on the retaining member and the strain relief member along a back-to-front direction and attaching the cover on the retaining member via glue.

10. The method as recited in claim 9 , further comprising a step of coupling the retaining member with the strain relief member via glue.

11. A cable connector assembly comprising:
a mating member including an insulative housing having a plurality of contacts disposed therein and enclosed within a metallic shell, said mating member defining a small front section and a large rear section along a front-to-back direction;
a cable located behind the mating member and including a plurality of wires respectively electrically connected to the corresponding contacts, respectively;
an insulative inner mold enclosing an region about an interface of said wires and said contacts; and
an insulative retaining member including a front wall with an opening through which the small front section forwardly extends snugly, and at least one lateral wall rearwardlty extending from a periphery of the front wall; and
an insulative outer mold enclosing the inner mold; wherein
said lateral wall is sandwiched between the outer mold and the inner mold radially.

12. The cable connector assembly as claimed in claim 11 , wherein glue is applied to an interface between the outer mold and the lateral wall.

13. The cable connector assembly as claimed in claim 12 , wherein said lateral wall forms at least one slot to receive the glue.

14. The cable connector assembly as claimed in claim 11 , wherein glue is applied to an interface between the inner mold and the lateral wall.

15. The cable connector assembly as claimed in claim 11 , wherein the inner mold contacts the outer mold in a first lateral direction while isolated from the outer mold in a second lateral direction perpendicular to said first lateral direction.

16. The cable connector assembly as claimed in claim 11 , wherein said retaining member forms a short tubular structure around the front wall, and said lateral wall extends rearwardly from a rear edge of the short tubular structure.

17. The cable connector assembly as claimed in claim 11 , wherein said inner mold further includes a strain relief structure to surround the cable, and said outer mold defines a flange structure at the rear end to contact the strain relief structure radially.

18. The cable connector assembly as claimed in claim 11 , wherein said front wall is located adjacent to a boundary between the small front section and the large rear section.
