Single battery housing assembly

1. A battery housing for use with a night vision device, the housing being configured to contain a battery and a circuit board, the housing being further configured to cooperate with fasteners for removably securing the housing to the night vision device and comprising:

a battery holder for retaining a single battery and configured to be carried in the housing, the battery holder being operatively associated with electrical contacts for connecting the battery in an electrical circuit and including a sleeve member, wherein the sleeve member is electronically conductive, the housing is conductive, and the electrical contacts include

a first conductor electrically connected to the sleeve member for electrical connection to a first terminal of the battery, the first conductor outwardly projecting from an outer surface of the sleeve and protruding through a first opening in the housing, and

a second conductor for electrical connection to a second terminal of the battery, the second conductor protruding through an opening in an end portion of the sleeve and protruding through a second opening in the housing.

2. The battery housing in accordance with claim 1 , wherein a cap is removably carried by the sleeve member, the cap being located on the outside of the sleeve and providing access to the interior of the sleeve when the cap is removed from the sleeve member.

3. A battery housing in accordance with claim 1 , further comprising a step-up arrangement for increasing the voltage of the single battery.

4. The battery housing in accordance with claim 1 , wherein the first conductor is integral with the sleeve and further comprising a support for the first conductor, the support being integral with an end of the first conductor and with the outer surface of the sleeve.

5. The battery housing in accordance with claim 1 , further comprising:

a first spring for electrical coupling to the first terminal of the battery, and

a second spring for electrical coupling to the second terminal of the battery, said second spring being inside the end portion of the sleeve and integral with the second conductor.

6. The battery housing in accordance with claim 5 , further comprising:

a spacer, inside the end portion of the sleeve, between the second spring and the second terminal of the battery for providing reverse polarity protection for the battery and for stabilizing the battery; and

a stop inside the cap for limiting movement of the spacer and the battery.

7. The battery housing in accordance with claim 5 , wherein an inner surface of the cap has a groove to receive the first spring, threads to provide an interface with a first segment of an outer surface of the sleeve member, and an area to provide an interface for a second segment of the outer surface of the sleeve member.

8. A battery housing comprising:

a sleeve for receiving a battery, the sleeve having an outer surface;

a first conductor for electrical connection to a first terminal of the battery, the first conductor being integral with the sleeve and projecting outwardly from the outer surface of the sleeve at an angle with respect to an axis of the sleeve; and

a second conductor projecting from an end portion of the sleeve for electrical connection to a second terminal of the battery.

9. The battery housing of claim 8 , further comprising

a first spring for electrically coupling to the first terminal of the battery;

a second spring for electrical coupling to the second terminal of due battery, said second spring being inside the end portion of the sleeve and integral with the second conductor;

a spacer, inside the end portion of the sleeve, between the second spring and the second terminal of the battery for providing reverse polarity protection for the battery and for stabilizing the battery; and

a stop inside the end portion of the sleeve for limiting movement of the spacer and the battery.

10. The battery housing of claim 8 , wherein the end portion of the sleeve is a first end portion, and further comprising a second end portion of the sleeve and threads on a portion of an outer surface of the second end portion.

11. The battery housing of claim 10 , further comprising:

a cover coupled to the second end portion of the sleeve, an inner surface of the cover having

a groove to receive the first spring,

other threads to provide an interface with the threads on the outer surface of the sleeve, and

an area to provide an interface with another portion of the outer surface of the sleeve.

12. A battery housing comprising:

an electrically conductive sleeve for receiving a battery;

an electrically conductive housing for receiving the sleeve;

a first conductor electrically connected to the sleeve for electrical connection to a first terminal of the battery and to electric circuitry, the first conductor outwardly projecting from an outer surface of the sleeve and protruding through a first opening in the housing; and

a second conductor for electrical connection to a second terminal of the battery and to the electric circuit, the second conductor protruding through an opening in an end portion of the sleeve and protruding through a second opening in the housing.

13. The battery housing of claim 12 , wherein a portion of the sleeve protrudes from the housing, and further comprising a cover coupled to the portion of the sleeve protruding from the housing.
