Abstract

An arrangement for removably mounting filter or transient suppression components in a connector includes an insulator having a plurality of feedthrough contact openings and a plurality of openings for the components. The components are electrically connected to the contacts via fixed conductive clips in the component openings, the clips including integral spring members for engaging the feedthrough contacts. The components are also connected to a ground plate by spring members extending into the component openings for biasing each component against a respective clip, thereby permitting separate removal of each component and contact pin.

Claims

1. A connector, comprising:

a conductive shell;

a first insulator member supported by said shell and including a first aperture extending through said insulator member, said first aperture arranged to permit passage of a feedthrough contact, and a second aperture extending partially through said insulator member in communication with said first aperture, said second aperture including a floor and two opposed walls which support an electrical component having first and second electrodes;

a conductive clip secured within said second aperture and including means for electrically contacting said feedthrough contact;

a ground plate including means for electrically connecting said ground plate to said shell, and a resilient ground contact member which extends into said second aperture,

wherein said ground contact member is biased against said first electrode, thereby biasing said second electrode against said conductive clip in order to establish an electrical connection between said feedthrough contact and said second electrode via said conductive clip, and between said first electrode and said shell via said ground plate.

2. An electrical connector as claimed in claim 1, further comprising a passageway in communication with said first and second apertures and extending from said second aperture to an outter surface of said insulator member for receiving said means for establishing an electrical connection between said clip and said contact pin.

3. A connector as claimed in claim 2, wherein said clip is a plate spring and said means for establishing an electrical connection between said clip and said feedthrough contact comprises a spring member extending from and integral with said clip, said spring member being arranged to extend into said first aperture prior to insertion of a feedthrough contact, and to be pushed into said passageway in response to insertion of the feedthrough contact, thereby biasing said spring member against said feedthrough contact.

4. A connector as claimed in claim 1, wherein said ground plate comprises a single stamped and formed sheet of conductive material.

5. A connector as claimed in claim 1, wherein said clip comprises means including barbs which penetrate said two walls to secure said clip within said insulator member.

6. A connector as claimed in claim 1, further comprising a second insulator member arranged to sandwich said ground plate between said first and second insulator members.

7. A connector as claimed in claim 1, wherein said insulator member includes a raised portion projecting into an opening in said ground plate for insulating said ground plate from said feedthrough contact.

8. A connector as claimed in claim 1, wherein said first insulator member comprises a plurality of said first and second apertures, each second aperture including one of said conductive clips secured therein and, extending into each second aperture, one of said resilient ground contact members integral with said ground plate, wherein the feedthrough contacts and components inserted into respective ones of said first and second apertures may be separately removed for replacement or repair.

9. An arrangement for removably mounting an electrical component in an electrical connector, comprising:

electrical connector, comprising;

an insulator member having a feedthrough contact opening and an electrical component opening in communication with said contact opening;

a conductive clip and an electrical component secured in said component opening;

means on said conductive clip which engages a feedthrough contact inserted into said contact opening to establish an electrical connection between said feedthrough contact and said clip;

grounding means for electrically connecting a ground electrode of said component with ground, said grounding means including biasing means which biases a live electrode of said component against said conductive clip.

10. An arrangement as claimed in claim 9, wherein said clip and said ground electrode are planar.

11. An arrangement as claimed in claim 9, wherein said means on said conductive clip comprise a spring member integral with said clip.

12. An arrangement as claimed in claim 9, wherein said grounding means is a ground plate and said biasing means is a conductive member integral with said ground plate and extending into said component opening.

13. A connector as claimed in claim 12, wherein said clip comprises means including barbs which penetrate said two walls to secure said clip within said insulator member.

14. A connector as claimed in claim 12, further comprising a second insulator member arranged to sandwich said ground plate between said first and second insulator members.

15. A connector as claimed in claim 12, wherein said insulator member includes a raised portion projecting into an opening in said ground plate for insulating said ground plate from said feedthrough contact.
