Abstract

Electrical connector that includes a pair of electrical contacts. Each of the electrical contacts has a mounting portion and a flexible mating portion that is configured to electrically engage a conductive component. The mating portions of the electrical contacts are separated by a component-receiving space and oppose each other across the component-receiving space. The electrical connector also includes a spring clip that is configured to mechanically engage the mating portions and is movable with respect to the mounting portions. The spring clip has a pair of opposing clip arms and a bridge member that joins the clip arms. The clip arms are separated by a gap with the mating portions positioned therebetween. The clip arms are biased against the corresponding mating portions. The spring clip has a dielectric member that is positioned to electrically isolate at least one of the electrical contacts.

Claims

1. An electrical connector comprising:

a pair of electrical contacts, each of the electrical contacts having a mounting portion that is configured to be mounted to an electrical element and a flexible mating portion that is configured to electrically engage a conductive component, the mating portions of the electrical contacts being separated by a component-receiving space and opposing each other across the component-receiving space; and

a spring clip that is configured to mechanically engage the mating portions of the electrical contacts and is movable with respect to the mounting portions, the spring clip having a pair of opposing clip arms and a bridge member that joins the clip arms, the clip arms being separated by a gap with the mating portions positioned therebetween, the clip arms being biased against the corresponding mating portions, wherein the spring clip has a dielectric member that is positioned between the spring clip and at least one of the electrical contacts to electrically isolate the spring clip from said at least one of the electrical contacts.

2. The electrical connector in accordance with claim 1, wherein the dielectric member includes first and second dielectric pads, the first dielectric pad being disposed on one of the clip arms and extending toward one of the mating portions, the second dielectric pad being disposed on the other clip arm and extending toward the other mating portion.

3. The electrical connector in accordance with claim 1, wherein the spring clip includes a clip body and the dielectric member comprises an insulative layer that is attached to a surface of the clip body.

4. The electrical connector in accordance with claim 1, wherein the electrical contacts have a cavity space therebetween, the electrical connector further comprising an insulative partition that is located within the cavity space between the electrical contacts.

5. The electrical connector in accordance with claim 4, wherein the insulative partition is held by the electrical contacts.

6. The electrical connector in accordance with claim 4, wherein the insulative partition moves with the electrical contacts when the conductive component engages the mating portions in a misaligned manner.

7. The electrical connector in accordance with claim 1, further comprising a connector housing having a socket opening that is configured to receive an edge of the conductive component, the electrical contacts positioned in the socket opening such that one of the electrical contacts is configured to engage a first side of the conductive component and the other electrical contact is configured to engage a second side of the conductive component.

8. The electrical connector in accordance with claim 1, wherein the spring clip has a clip body that is stamped from sheet material and formed to include the bridge member and the clip arms, the dielectric member being at least one of a dielectric pad or an insulative layer that is attached to the clip body.

9. The electrical connector in accordance with claim 1, wherein each of the electrical contacts extends longitudinally between front and rear ends and has inner and outer surfaces, the inner surfaces of the electrical contacts facing each other and having an insulative partition located therebetween, the outer surfaces of the electrical contacts facing the spring clip, wherein the dielectric member of the spring clip is configured to engage the outer surfaces of the electrical contacts.

10. The electrical connector in accordance with claim 1, wherein the spring clip moves relative to the mounting portions when the conductive component is advanced into the component-receiving space along a mating direction and engages the mating portions in a misaligned manner, the spring clip being permitted to rotate about an axis that extends substantially perpendicular to the mating direction.

11. The electrical connector in accordance with claim 1, further comprising the electrical element, wherein the electrical contacts are electrically independent from each other and configured to carry different voltages.

12. An electrical connector comprising:

a connector housing having an interior cavity and a socket opening that provides access to the interior cavity, the socket opening configured to receive a conductive component;

a pair of electrical contacts positioned in the interior cavity, each of the electrical contacts having a flexible mating portion that is configured to electrically engage the conductive component proximate to the socket opening, the mating portions being separated by a component-receiving space and opposing each other across the component-receiving space; and

a spring clip that is configured to mechanically engage the mating portions of the electrical contacts, the spring clip having a pair of opposing clip arms and a bridge member that joins the clip arms, the clip arms being biased against the mating portions located between the clip arms, wherein the spring clip has a dielectric member that is positioned between the spring clip and at least one of the electrical contacts to electrically isolate the spring clip from the electrical contacts.

13. The electrical connector in accordance with claim 12, wherein the dielectric member includes first and second dielectric pads, the first dielectric pad being disposed on one of the clip arms and extending toward one of the mating portions, the second dielectric pad being disposed on the other clip arm and extending toward the other mating portion.

14. The electrical connector in accordance with claim 12, wherein the spring clip includes a clip body and the dielectric member comprises an insulative layer that is attached to a surface of the clip body.

15. The electrical connector in accordance with claim 12, wherein the electrical contacts have a cavity space therebetween, the electrical connector further comprising an insulative partition that is located within the cavity space between the electrical contacts.

16. The electrical connector in accordance with claim 15, wherein the insulative partition is held by the electrical contacts.

17. The electrical connector in accordance with claim 15, wherein the insulative partition moves with the electrical contacts when the conductive component engages the mating portions in a misaligned manner.

18. The electrical connector in accordance with claim 12, further comprising a connector housing having a socket opening that is configured to receive an edge of the conductive component, the electrical contacts positioned in the socket opening such that one of the electrical contacts is configured to engage a first side of the conductive component and the other electrical contact is configured to engage a second side of the conductive component.

19. The electrical connector in accordance with claim 12, wherein the spring clip has a clip body that is stamped from sheet material and formed to include the bridge member and the clip arms.

20. The electrical connector in accordance with claim 12, wherein the spring clip moves relative to the connector housing when the conductive component is advanced into the component-receiving space along a mating direction and engages the mating portions in a misaligned manner, the spring clip being permitted to rotate about an axis that extends substantially perpendicular to the mating direction.
