## Abstract

A battery connecting device for mounting a power source battery in a battery accommodating space of an electronic appliance. The device includes a plurality of resilient strip-like connection terminals attached directly to a wall defining the battery accommodation space by means of slits formed in the wall. In consequence, the size of the battery accommodation space and, hence, the size of the electronic appliance as a whole can be reduced advantageously.

## Claims

### Claim 1

A battery connecting device comprising: at least a connection terminal constituted by a resilient strip-like member having one end soldered to a lead and the other end bent to form a retainer tab, the intermediate portion of said strip-like member being bent resiliently to form a contact portion of said connecting terminal; and a wall defining a battery accommodating space and having a first slit adapted to permit at least said retainer tab and said contact portion of said connection terminal to pass therethrough and a second slit adapted to permit at least said retainer tab to pass therethrough, said connection terminal being directly attached to said wall through said first and second slits in such a manner that said contact portion appears at the same side of said wall as the battery while said retainer tab and said end soldered to said lead appear at the opposite side of said wall to said battery and that a reactional force is generated to press said contact portion of said connecting terminal toward said battery.

### Claim 2 (depends on 1)

A battery connecting device as claimed in claim 1, wherein a plurality of pairs of slits each consisting of said first and second slits are formed in the same wall defining said battery accommodating section and that a plurality of connection terminals are inserted to respective pairs of said slits so as contact portion to extend in the direction of insertion of said battery.

### Claim 3 (depends on 2)

A battery connecting device as claimed in claim 2, wherein three connection terminals including a positive electrode terminal, negative electrode terminal and a charging electrode terminal are used and two of said connection terminals being arranged in parallel to each other while the remainder one connection terminal is arranged at a right angle to the parallel connection electrodes.

### Claim 4 (depends on 2)

A battery connection device as claimed in claim 2, wherein said first and second slits of each pair of slits are arranged such that said first slit is disposed at the outer side of said second slit as viewed in the direction of insertion of the associated connection terminal.
