Abstract

A connector for connecting to at least a cable (5), includes an insulated housing (2); a plurality of contacts (31, 32) supported by the insulated housing (2), said contacts including at least two pairs of signal contacts (31) and at least a grounding contact (32); said signal contacts (31) divided into two juxtaposed differential contact pairs (310); each of the differential contact pairs (310) including a first signal contact (310A) and a second signal contact (310B) juxtaposed closely to each other; each of the first and second signal contacts (310A, 310B) having a retention portion, a mating portion extending forward from the retention portion and a tail portion extending rearward from the retention portion, and a first side (3101) and a second side (3103) which are divergent from a front segment of the retention portion to an free end of the mating portion such that a first distance (30′) between the retention portions of two adjacent differential contact pairs of signal contacts is smaller than a second distance (30) between the mating portions of the same differential contact pairs of signal contacts; and said grounding contact having a mating portion disposed between the mating portions of the two adjacent differential contact pairs.

Claims

1. An electrical contact insert for a cable connector assembly, comprising:

a set of signal contacts, including at least two differential contact pairs arranged in juxtaposed manner;

each of the differential contact pairs including a first signal contact and a second signal contact juxtaposed closely to each other;

each of the first signal and second signal contacts having a base portion and a contact engaging portion, and a first side and a second side which are divergent from the base portion to an free end of the contact engaging portion such that a first distance between the base portion of two adjacent differential contact pairs of signal contacts is smaller than a second distance between the contact engaging portion of the same differential contact pairs of signal contacts, wherein a first gap formed between the contact engaging portions of the differential contact pair is equal to a second gap formed between the base portions of the same differential contact pair, wherein a grounding contact has a mating portion disposed between the contact engaging portions of the two differential contact pairs and a tail portion being apart from the base portions of the two differential contact pairs and arranged at a different level, wherein the signal contacts and the grounding contact are integrated with an insulator.

2. The electrical contact insert as recited in claim 1, wherein the first side has a curve surface and the second side has a planar surface.

3. A connector for connecting to at least a cable, comprising:

an insulated housing;

a plurality of contacts supported by the insulated housing, said contacts including at least two pairs of signal contacts and at least a grounding contact;

said signal contacts divided into two juxtaposed differential contact pairs;

each of the differential contact pairs including a first signal contact and a second signal contact juxtaposed closely to each other;

each of the first and second signal contacts having a retention portion, a mating portion extending forward from the retention portion and a tail portion extending rearward from the retention portion, and a first side and a second side which are divergent from a front segment of the retention portion to an free end of the mating portion such that a first distance between the retention portions of two adjacent differential contact pairs of signal contacts is smaller than a second distance between the mating portions of the same differential contact pairs of signal contacts; and

said grounding contact having a mating portion disposed between the mating portions of the two adjacent differential contact pairs, wherein a spacer combined with the contacts is assembled to the insulated housing, wherein the signal contacts and grounding contacts are insert-molded with the spacer, wherein the mating portions of the signal contacts and the grounding contact extend beyond a front face of the spacer, and tail portions of the signal contacts and the grounding contact are respectively located on a top surface and bottom surface of a rear portion of the spacer, wherein the spacer has an inserter portion received in a cavity defined in a rear portion of the insulated housing, wherein two arms extends rearward from lateral sides of a back surface of the insulated housing, wherein a pair of flange portions formed at lateral sides of the spacer are accommodated in guiding passages of the two arms.

4. The connector as recited in claim 3, wherein a tail portion of the grounding contact and the tail portions of the signal contacts are arranged at different levels.

5. The connector as recited in claim 3, wherein a distance formed between each of the differential contact pairs is constant.

6. The connector as recited in claim 3, wherein the insulated housing has a sunken portion defined in the front portion thereof.

7. The connector as recited in claim 6, wherein a plurality of grooves located in the sunken portion to receive the mating portions of the signal contacts and grounding contacts.

8. The connector as recited in claim 3, wherein additional two grounding contacts have mating portions respectively disposed outside of the mating portions of the two differential contact pairs.

9. The connector as recited in claim 8, wherein retention portions of the grounding contacts are interconnected together one another.

10. An electrical connector comprising:

an insulative housing defining a mating port;

a plurality of signal contacts arranged as differential pairs, disposed in the housing with a juxtaposed manner at a first level, each of said signal contacts including a front mating section and a rear tail section; and

a plurality of grounding contacts disposed in the housing essentially at a second level, each of said grounding contacts including a front mating portion and a rear tail portion;

wherein the tail sections of the signal contacts and the tail portions of the grounding contacts are located at different planes while the mating sections of the signal contacts and the mating portions of the grounding contacts are located in a same plane under a condition that the mating sections of every adjacent two corresponding differential pairs are separated by the mating portion of the corresponding grounding contact, wherein said grounding contacts are unified together as one piece, wherein a plurality of wires are provided behind the tail sections of the signal contacts and the tail portions of the grounding contacts under a condition that in each of said wires, a pair of signal conductors thereof are mechanically and electrically connected to the tail sections of the corresponding differential pair, and a drain line thereof is mechanically and electrically connected to the tail portion of the corresponding grounding contact.
