Abstract

A battery receptor to make it possible to insert a battery having a protruding end and a flat end in either orientation which includes a first pair of contacts which is mounted at one end of the receptor and which is capable of accommodating one end of the battery and a second pair of contacts which is mounted at the other end of the receptor for accommodating the other end of the battery. Each of the pair of contacts is made up of two members--an electrically conductive retainer member and an electrically conductive flat contact, both of which are rigidly connected to the battery receptor. The retainer member is in electrical contact with one of the two receptor electrical contacts while the flat contact is in electrical contact with the other of the receptor electrical contacts. The retainer member is sized and shaped to retain the flat end of the battery but not the protruding end of the battery while the flat contact, which is adjacent to, and separated from, the retainer member and on the side of the retainer member away from the battery, is capable of electrically contacting the protruding end of the battery.

Claims

1. A battery receptor to render operative an inserted battery having a protruding portion and a flat portion regardless of the orientation of the inserted battery, comprising:

(a) a first pair of contacts mounted at one end of the receptor for accommodating one end of the battery;

(b) a second pair of contacts mounted at the other end of the receptor for accommodating the other end of the battery;

each of said pair of contacts characterized in that each pair includes;

(i) an electrically conductive retainer member rigidly connected to, or integrally formed with, the battery receptor, said retainer member being in electrical contact with a first receptor electrical contact, said retainer member being sized and shaped to retain the flat end of the battery but not the protruding end of the battery; and

(ii) an electrically conductive flat contact rigidly connected to, or integrally formed with, said receptor, said flat contact being in electrical contact with a second receptor electrical contact, said fiat contact being adjacent to, and separated from, said retainer member and on the side of said retainer member away from the battery.

2. A battery receptor as in claim 1, wherein each of said retainer elements is formed with a cutout sized to allow the protruding portion of the battery to penetrate the plane of said retainer element.

3. A battery receptor as in claim 1, wherein the protruding portion of the battery is the positive end of the battery and said retainer members are in electrical contact with the positive contact of said receptor.

4. A battery receptor as in claim 1, wherein the protruding portion of the battery is the negative end of the battery and said retainer members are in electrical contact with the negative contact of said receptor.

5. A battery receptor as in claim 1, wherein said retainer member and said flat contact of each of said pair of contacts are rigidly connected to each other.

6. A battery receptor as in claim 5, wherein each of said pair of contacts features an electrically insulating material interposed between said retainer member and said flat contact.

7. A battery receptor as in claim 6, wherein the inner-facing edge of said insulating material extends inward beyond the inward-facing edge of said retainer member.

8. A battery receptor as in claim 5, wherein the separation between said retainer member and said fiat contact of each of said pair of contacts is related to the axial extent of the protruding portion of the battery.

9. A battery receptor as in claim 8, wherein said separation is from about 0.25 to about 0.75 of the axial extent of the protruding portion of the battery.

10. A battery receptor as in claim 8, wherein said separation is about one half of the axial extent of the protruding portion of the battery.
