Abstract

An electrical connector for transmitting data signals between the insulated conductors of a first data cable and corresponding insulated conductors of a second data cable, including a socket shaped to at least partially receive a plug of said first data cable; a plurality of insulation displacement contact slots shaped to receive end sections of the conductors of the second data cable; a plurality of electrically conductive contacts including resiliently compressible spring finger contacts extending into the socket for electrical connection with corresponding conductors of the first cable; insulation displacement contacts seated in corresponding insulation displacement contact slots for effecting electrical connection with corresponding conductors of the second data cable; and mid sections extending therebetween; and a plurality of capacitive plates coupled to respective ones of the mid sections of the contacts by electrically conductive stems, wherein the capacitive plates induce capacitive coupling between adjacent contacts.

Claims

1. An electrical connector for transmitting data signals between the insulated conductors of a first data cable and corresponding insulated conductors of a second data cable, comprising:

(a) a housing comprising;

(i) a front part including a socket shaped to at least partially receive a plug of said first data cable; and

(ii) a back part including a plurality of insulation displacement contact slots shaped to receive end sections of the conductors of the second data cable;

(b) a plurality of electrically conductive contacts including resiliently compressible spring finger contacts extending into the socket for electrical connection with corresponding conductors of the first cable;

insulation displacement contacts seated in corresponding insulation displacement contact slots for effecting electrical connection with corresponding conductors of the second data cable; and

mid sections extending therebetween; and

(c) a plurality of capacitive plates coupled to respective ones of said mid sections of the contacts by electrically conductive stems,

wherein the capacitive plates induce capacitive coupling between adjacent contacts.

2. The electrical connector claimed in claim 1, wherein the capacitive plates are coupled to common points of said mid sections of the contacts.

3. The electrical connector claimed in claim 1, wherein said mid sections of the contacts lie generally in a common plane.

4. The electrical connector claimed in claim 3, wherein the stems extend in a substantially normal direction to said common plane.

5. The electrical connector claimed in claim 1, wherein the stems extend substantially one millimeter away from respective mid sections of the contacts.

6. The electrical connector claimed in claim 1, wherein the spring finger contacts are coupled to respective mid sections by elbows such that the spring finger contacts are bent away from said common plane towards the socket.

7. The electrical connector claimed in claim 6, wherein the stems are coupled to respective mid sections of the contacts adjacent corresponding elbows.

8. The electrical connector claimed in claim 1, wherein relative movement between the mid sections of the contacts is inhibited by a fastener.

9. The electrical connector claimed in claim 1, wherein relative capacitance between the capacitive plates is substantially unaffected by movement of the spring finger contacts.
