Abstract

A cable connector assembly has a first connector, a second connector and a ribbon cable connecting the first and the second connectors. The first connector includes a first insulating housing, a number of first contacts and a first shielding covering the first insulating housing. Each first contact includes a first contacting portion, a first retaining portion and a first connection portion. The first shielding has a first grounding section. The second connector includes a second insulating housing, a number of second contacts and a second shielding. Each second contact includes a second contacting portion, a second retaining portion and a second connection portion. The second shielding has a second ground section. The ribbon cable includes a number of wires, each wire having one end electrically connecting with the first connection portions and the first grounding section and having the other end electrically connecting the second connection portions and the second ground section.

Claims

1. A cable connector assembly, comprising:

a first connector, said first connector comprising;

a first insulating housing;

a plurality of first contacts assembled on said first insulating housing, each of said first contacts comprising a first contacting portion, a first retaining portion and a first connection portion;

a first shielding covering said first insulating housing, said first shielding having a first grounding section;

a second connector, said second connector comprising;

a second insulating housing;

a plurality of second contacts assembled on said second insulating housing, each of said second contacts comprising a second contacting portion, a second retaining portion and a second connection portion;

a second shielding covering said second insulating housing, said second shielding having a second ground section; and

a ribbon cable electrical connecting said first and said second connector, said ribbon cable comprising a plurality wires, each wire having one end electrically connecting with said first connection portions and said first grounding section and having the other end electrically connecting said second connection portions and said second ground section.

2. The cable connector assembly as claimed in claim 1, wherein said first contacts are divided into a first group of first contacts and a second group of first contacts, and wherein said first and said second groups of first contacts extend along different planes.

3. The cable connector assembly as claimed in claim 2, wherein said second contacts are divided into a first group of second contacts and a second group of second contacts, and wherein said first and said second groups of second contacts extend along different planes.

4. The cable connector assembly as claimed in claim 3, wherein said first shielding comprises a first top wall, a first bottom wall opposite to said first top wall, a pair of first side walls connecting said first top wall and said first bottom wall, and wherein a pair of first ground sections extends oppositely from rear ends of said first side walls.

5. The cable connector assembly as claimed in claim 4, wherein said second shielding comprises a second top wall, a second bottom wall opposite to said second top wall, a pair of second side walls connecting said second top wall and said second bottom wall, and wherein a pair of second ground sections extends oppositely from rear ends of said second side walls.

6. The cable connector assembly as claimed in claim 5, wherein said plurality of wires includes a first group of wires and a second group of wires.

7. The cable connector assembly as claimed in claim 6, wherein said first group of wires electrically connect part of the second group of first contacts with part of the second group of second contacts, and connect one of first ground sections with one of second ground sections, and wherein said second group of wires electrically connect rest of the second group of first contacts with rest of the second group of second contacts, and connect the other one of first ground sections with the other one of second ground sections.

8. The cable connector assembly as claimed in claim 7, wherein said first group of wires and said second group of wires are staggeredly arranged between said first connector and said second connector.

9. The cable connector assembly as claimed in claim 8, wherein said plurality of wires further comprises a third group of wires, and wherein said third group of wires connect said first group of first contacts and said first group of second contacts, and wherein said third group of wires have opposite ends located at different planes.

10. The cable connector assembly as claimed in claim 9, wherein each group of wires comprises four wires.
