Abstract

A battery housing comprising a main body portion, a socket in the main body portion shaped to receive a battery, contacts disposed at one end of the socket adapted to connect with correspondingly disposed electrodes on the battery, and a lid adapted to open and close over the socket, the lid including means for urging the battery electrodes into close connection with the contacts.

Claims

1. A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said means for urging comprising a latch for insertion into said socket at an end thereof opposite said contacts, said latch having an inward bend for forcing said battery toward said opposite end upon closing said lid, whereby said electrodes are urged into close connection with said contacts, and further including a resilient tab projecting from said lid at an acute angle thereto for forcing said battery into said socket upon closing said lid.

2. The battery housing of claim 1 wherein said lid is pivotally connected to said main body portion.

3. The battery housing of claim 1 wherein said lid includes an aperture for mounting said housing to a screw.

4. The battery housing of claim 1 wherein said main body portion is dimensioned to contain smoke alarm circuitry.

5. The battery housing of claim 1 wherein said main body portion is indented to receive said lid in closed position such that said lid and main body portion form a flat surface.

6. The battery housing of claim 1 wherein said socket conforms generally to a rectangular parallelepiped in shape.

7. The battery housing of claim 1 wherein said socket includes a cavity for receiving said latch, said latch being urged into connection with said cavity due to said inward bend being displaced by said battery.

8. The battery housing of claim 7 wherein said latch includes a tooth portion extending from a distal end thereof.

9. The battery housing of claim 8 wherein said cavity is bounded on one side by a surface against which said tooth portion rests for securing said lid upon closure thereof.

10. The battery housing of claim 1 further including a pair of differently sized rectangular slots in said socket for aligning said electrodes of the battery with like polarity ones of said contacts.

11. A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said lid including an aperture for mounting said housing to a screw.

12. A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said means for urging comprising a latch adapted to be inserted into said socket at an end thereof opposite said contacts, said latch having an inward bend for forcing said battery toward said opposite end upon closing said lid, whereby said electrodes are urged into close connection with said contacts, said socket including a cavity for receiving said latch, said latch being urged into connection with said cavity due to said inward bend being displaced by said battery.

13. A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, and further including a pair of differently sized rectangular slots in said socket for aligning said electrodes of the battery with like polarity ones of said contacts.
