Abstract

A cable connector assembly, comprising comprises: a plurality of contacts (2) defining a plurality of first contacts (27) which may be used as power contacts and a plurality of second contacts (28), an insulative housing (1) molding outside the contacts (2), a flat-shaped cable (3) connecting with the contacts (2), the cable (3) comprises a plurality of coaxial wires arranged along the level direction, each coaxial wire comprises a plurality of inner conductors (30), two inner conductors (30) are connected with a first contact (27), and one inner conductor (30) is connected with a second contact (28), a metallic shell (4) shielding outside the insulative housing (1).

Claims

1. A cable connector assembly, comprising:

a plurality of contacts defining first contacts and second contacts;

an insulative housing receiving the contacts;

a flat-shaped cable connecting with the contacts, the cable comprises a plurality of coaxial wires side by side arranged along a horizontal direction, each coaxial wire having an inner conductor, and the middle one pair of conductors connected with the second contacts in a one-to-one manner, the other two pairs of inner conductors which are respectively located on two lateral sides, connected with the first contacts in a two-to-one manner;

a metallic shell shielding outside the insulative housing.

2. The cable connector assembly as claimed in claim 1, wherein the insulative housing comprises a base portion and a tongue portion extending backwardly from the base portion, a plurality of terminal receiving grooves are formed in the upper surface of the tongue portion.

3. The cable connector assembly as claimed in claim 1, wherein each coaxial wire comprises a braiding layer closing the inner conductor and the inner conductor is exposed from the front edge of the braiding layer.

4. The cable connector assembly as claimed in claim 3, the metallic shell comprises a shielding portion shielding the insulative housing and a supporting portion behind the shielding portion for supporting the braiding layer and electrically connecting with the braiding layer.

5. The cable connector assembly as claimed in claim 2, wherein a pair of locking holes are recessed downwardly from the upper surface of the base portion.

6. The cable connector assembly as claimed in claim 5, wherein the metallic shell comprises a top shell and a bottom shell assembled to each other, and a pair of locking tabs mating with the locking holes are formed in the lateral walls of the bottom shell.

7. The cable connector assembly as claimed in claim 6, wherein a pair of tabs are formed in the two lateral walls of the top shell and the tabs are extending inwardly from the lateral walls.

8. The cable connector assembly as claimed in claim 7, wherein a pair of holes are formed in the bottom shell for mating with the tabs and the holes is running through the upper and lower surface of the bottom shell.

9. The cable connector assembly as claimed in claim 7, wherein a pair of posts are defined in the lateral sides of the tongue portion and a pair of gaps are formed between the posts and the lateral walls behind the locking tabs.

10. The cable connector assembly as claimed in claim 9, wherein the front section of the lateral walls of the top shell are disposed in the gaps.

11. An electrical connector comprising:

an insulative housing defining a mating tongue with opposite upper and bottom surfaces;

a plurality of contacts disposed in the housing, each of the contacts defining a front contacting section exposed upon the upper surface of the mating tongue and a rear tail section;

a cable including a plurality of wires located behind the housing, each of said wires defining an inner conductor connected to the corresponding contact, an inner insulative layer enclosing the inner conductor, a braiding layer enclosing the inner insulative layer, and an outer jacket enclosing the braiding layer; and

a metallic shell having a front portion covering the bottom surface, and a rear portion connecting to the braiding layer;

wherein

said wires include six wires side by side transversely arranged with one another at equal intervals, including two leftmost wires and two right most wires commonly sandwiching two middle wires, while the contacts include four contacts, including a leftmost contact and a rightmost contact commonly sandwiching two middle contacts, with different intervals on the corresponding contacting sections thereof;

wherein

the two middle wires are respectively connected to the rear tail sections of the corresponding two middle contacts while the two leftmost wires are commonly connected to the rear tail section of the leftmost contact and the two rightmost wires are commonly connected to the rear tail section of the rightmost contact.

12. The electrical connector as claimed in claim 11, wherein an overmold encloses a rear portion of the housing and a front portion of the cable.

13. The electrical connector as claimed in claim 11, wherein the rear portion of the shell includes a first part and a second part located by two sides of the corresponding wires while assembled to each other.

14. The electrical connector as claimed in claim 11, wherein front end regions of the two middle wires extend offset away from each other while a front end region of an inner one of the two leftmost wires extends toward the outer one, and a front end region of an inner one of the two rightmost wires extends toward the outer one.
