Abstract

An improved structural arrangement for holding a battery having male and female terminals within the battery compartment of a portable electrical appliance includes two plate springs each connected at one end to the appliance circuitry and carrying, at the other end, one of the circuitry terminals for engagement with the corresponding battery terminal. The terminals of the battery are brought into engagement with the circuitry terminals simply by inserting the battery into the battery compartment against the elastic force of the plate springs. After engagement of the circuitry terminals with the battery terminals, the battery is held securely in place by the elastic force of the plate springs and contact between the mating terminals is likewise secured.

Claims

1. An improvement for an electrical apparatus for holding a battery which includes a pair of male and female terminals at one end thereof, the apparatus being of the type comprising a main body which includes a compartment therein for receiving the battery and a pair of female and male circuit terminals extending into the compartment and arranged for engagement with the respective male and female terminals of the battery, the improvement comprising:

first and second resilient, electrically conductive, plate springs rigidly secured at their end portions to the main body and extending into and terminating in the battery compartment, one of said plate springs carrying at its free end portion the female circuit terminal for engagement with the battery male terminal and the other of said plate springs carrying at its free end portion the male circuit terminal for engagement with the battery female terminal, said first and second plate springs being electrically isolated from each other, the compartment being sized so that when the battery terminals on one end of the battery are engaged by the plate springs the other end of the battery will engage a surface of the compartment opposite said plate springs.

2. The improvement in claim 1, wherein the plate springs are L-shaped, one portion of the "L" being connected to the main body and the other portion containing the terminal.
