Abstract

An environmentally sealed battery connector (100) includes a battery contact member (102) having a battery contact location (108). Battery connector (100) also includes a resilient seal member (118) having a battery mating ridge (110) which compresses against battery (204) and environmentally seals the point of contact between battery (204) and battery contact location (108).

Claims

1. An environmentally sealed battery connector for mating with a battery having a battery terminal surface, comprising:

a battery connector member having a battery contact area for contacting to the battery terminal surface; and

a resilient seal member mounted onto the battery connector and having a battery mating surface substantially surrounding the battery contact area, the battery mating surface sealably contacting the battery terminal surface once the battery contact area is mated to the battery terminal surface.

2. The environmentally sealed battery connector of claim 1, wherein the resilient seal member wraps around the battery connector member and is insert molded onto the battery connector member.

3. The environmentally sealed battery connector of claim 1, wherein the battery connector member is a conductive formed cantilevered spring contact.

4. The environmentally sealed battery connector of claim 3, wherein the resilient seal member is made from an elastomer material.

5. The environmentally sealed battery connector of claim 3, wherein the resilient seal member is made from silicone.

6. The environmentally sealed battery connector of claim 3, wherein the battery connector member is made from a single piece of metal.

7. The environmentally sealed battery connector of claim 3, wherein the battery connector member includes at least one resilient seal member retainer.

14. The radio housing assembly of claim 1, wherein the battery connector member further includes a retainer means which is inserted into the battery connector cavity and retains the battery connector member to the radio housing member.

8. A battery connector for environmentally sealing a battery having a battery terminal surface the battery connector comprising:

a cantilevered spring formed battery connector member having a battery contact area for mating to the battery terminal surface the battery connector member is formed from a single piece of conductive material; and

a resilient seal member mounted onto the cantilevered spring formed battery connector member and having a battery mating surface substantially surrounding the battery contact area the resilient seal member having a compressible battery mating ridge that substantially surrounds the battery mating area and is located on the battery mating surface of the resilient seal member the compressible battery mating ridge sealably contacts the battery terminal surface once the battery terminal is mated to the battery contact area the resilient seal member is formed from an elastomeric material which is wrapped around the cantilevered spring formed battery connector.

9. The environmentally sealed battery connector of claim 8, wherein the resilient seal member is insert molded onto the spring formed battery connector.

10. The environmentally sealed battery connector of claim 8, wherein the battery connector member further includes a retainer means for retaining the battery connector member to a housing member.

11. A radio housing assembly, comprising:

a radio housing member having at least one battery connector cavity;

a cantilevered spring formed battery connector member having a battery contact area for mating to a battery having a battery terminal surface; and

a resilient seal member having a battery mating surface substantially surrounding the battery contact area, and the battery mating surface having a compressible battery mating ridge that substantially surrounds the battery contact area and is located on the battery mating surface the compressible battery mating ridge sealably contacts the battery terminal surface once the battery terminal mates to the battery contact area providing for an environmental seal around the battery contact area.

12. The radio housing assembly of claim 11, wherein the resilient seal member is made from an elastomer material and is insert molded onto the battery connector member.

13. The radio housing assembly of claim 12, wherein the battery connector member is made from a single piece of metal which is spring formed.

15. The radio housing assembly of claim 11, wherein the cantilevered spring formed battery connector becomes mechanically loaded once the battery contact area mates with the battery terminal surface, causing the compressible battery mating ridge to compress against the battery terminal surface and seals the battery contact area.

16. A battery connector for environmentally sealing a battery having a battery terminal surface, the batter connector comprising:

a cantilevered spring formed battery connector member having a battery contact area for mating to the battery terminal surface, the battery connector member is formed from a single piece of conductive material; and

a resilient seal member mounted onto the cantilevered spring formed battery connector member, the resilient seal member substantially wrapping around the cantilevered spring formed battery connector and having a battery mating surface substantially surrounding the battery contact area, the resilient seal member having a compressible battery mating ridge that substantially surrounds the battery mating area and is located on the battery mating surface of the resilient seal member, the compressible battery mating ridge sealably contacts the battery terminal surface once the battery terminal is mated to the battery contact area and provides for an environmental seal around the battery contact area.
