Abstract

An cable assembly (100) includes an insulative housing (1); a plurality of terminals (2) combined with the insulative housing; at least one lens (3) mounted to the insulative housing; a cable (4) having a plurality of copper wires (41), a fiber wire (423) and a strength element (43); a cylindrical protective member (6) inserted into an interior of a front segment the cable, with the copper wires, the fiber wire and the strength element extending therethrough, said copper wires electrically connected with the terminals, and the fiber wire optically connected with the fiber; a retaining member having a cylindrical holding portion (51) and the protective member coaxially arranged to clamp the strength element therebetween; and a metallic shell (7) having frame (711) and an accommodating part (712) connected with the frame, the insulative housing enclosed in the frame, and the retaining member received in the accommodating part.

Claims

1. A cable assembly, comprising:

an insulative housing;

a plurality of terminals combined with the insulative housing;

at least one lens mounted to the insulative housing;

a cable having a plurality of copper wires, a fiber wire and a strength element;

a cylindrical protective member inserted into an interior of a front segment the cable, with the copper wires, the fiber wire and the strength element extending therethrough, said copper wires electrically connected with the terminals, and the fiber wire optically connected with the lens;

a retaining member having a cylindrical holding portion and the protective member coaxially arranged to clamp the strength element therebetween; and

a metallic shell having frame and an accommodating part connected with the frame, the insulative housing enclosed in the frame, and the retaining member received in the accommodating part.

2. The cable assembly as recited in claim 1, wherein the cable further includes a metallic braiding enclosing the copper wires, the fiber wires and the strength element.

3. The cable assembly as recited in claim 2, wherein the metallic braiding is sandwiched between the protective member and the holding portion of the retaining member.

4. The cable assembly as recited in claim 2, wherein the strength element is placed on the metallic braiding and collectively clamped between the protective member and the holding portion of the retaining member.

5. The cable assembly as recited in claim 1, wherein the retaining member further has two wing portions laterally projecting from a back edge of the holding portion.

6. The cable assembly as recited in claim 5, wherein there are two blocking portions spaced apart from each other and projecting upwardly from a back edge of the accommodating part.

7. The cable assembly as recited in claim 6, wherein the two wing portions are located in front of the two blocking portions and the cable backwardly extends outward via an opening between the two blocking portions.

8. A cable assembly, comprising:

an insulative housing having a longitudinal base portion with a top side and a front side perpendicular to the top side, at least one mounting cavity recessed backwardly from the front side of the base portion;

a plurality of terminals located on the top side of the insulative housing;

a number of lenses received in the mounting cavity;

a cable having a plurality of copper wires, a number of fiber wires and at least one strength element associated with the copper wires and the fiber wires;

a protective member mounted to a front segment the cable, with the copper wires, the fiber wires and the strength element extending therethrough, said copper wires electrically connected with the terminals, and the fiber wires optically connected with lenses;

a retaining member having a holding portion together with the protective member to clamp the strength element therebetween; and

a metallic shell enclosing the insulative housing and the retaining member.

9. The cable assembly as recited in claim 8, wherein the cable further includes a metallic braiding enclosing the copper wires, the fiber wires and the strength member, the metallic braiding is sandwiched between the protective member and the holding portion of the retaining member.

10. The cable assembly as recited in claim 9, wherein the protective member, the metallic braiding and the holding portion are coaxially arranged.

11. The cable assembly as recited in claim 9, wherein a front part of the strength element is exposed outward the metallic braiding and disposed on the metallic braiding and further sandwiched between the protective member and the holding portion of the retaining member.

12. The cable assembly as recited in claim 8, wherein the strength member is kevlar or nylon.

13. The cable assembly as recited in claim 8, wherein the retaining member further has two wing portions unitarily formed with the holding portion and extending oppositely.

14. The cable assembly as recited in claim 8, wherein there is a transversal beam formed on the top side of the base portion to position the terminals.

15. The cable assembly as recited in claim 8, wherein the metallic shell includes a first shell and a second shell assembled together to hold the retaining member.

16. A cable assembly comprising:

an insulative housing;

a plurality of contacts disposed in the housing;

a plurality of optical elements disposed in the housing;

a cable including a plurality of wires connected to the corresponding contacts, respectively, a plurality of fibers connected to the corresponding optical elements, at least one strength member associated with the wires and the fibers, a braiding surrounding the wires, the fibers and the strength member, and a jacket enclosing surrounding the braiding;

a protective sleeve inserted into the cable within the braiding while surrounding the wires, the fibers and the strength member; and

a retaining sleeve grasping the cable outside of the jacket;

wherein the strength member having one inner portion sandwiched between the outer protective sleeve and the inner wires and fibers in a radial direction.

17. The cable connector assembly as claimed in claim 16, wherein the sleeve member further includes an outer portion sandwiched between the retaining sleeve and the jacket.

18. The cable connector assembly as claimed in claim 17, wherein a front portion of the braiding is exposed upon the jacket and backward folded on an outer surface of the jacket, and the outer portion of the strength member is sandwiched between the retaining sleeve and the backward folded braiding in the radial direction.

19. The cable connector assembly as claimed in claim 16, wherein the retaining sleeve further including a pair of wings abutting against a rear wall of a metallic shell, said shell enclosing the housing.
