ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a battery stage module, especially to a battery stage module, which has simple structure and easy assembling.
BACKGROUND IF THE INVENTION
The conventional consumer electronic devices using battery as primary or auxiliary power source generally has battery stage
10
arranged on a case
1
thereof and having a battery chamber
100
, as shown in FIG.
1
. The battery chamber
100
has two conductive members
101
in metal spring or tongue forms on both sides thereof and connected to positive and negative poles of battery. As shown in
FIG. 2
, the conductive members
101
are fixed to corresponding contacts
20
on a circuit board
2
to provide connection between the battery and the circuit board
2
.
The battery stage
10
is generally integrally formed on the case
1
and the conductive members
101
are soldered to the contacts
20
on the circuit board
2
or connected to the contacts
20
through wiring in advance. The conductive members
101
pass through corresponding through holes
102
on both sides of the battery chamber
100
and are clamped by the through holes
102
when the circuit board
2
is assembled to the case
1
. The soldering and wiring task for the conductive members
101
are cumbersome and the conductive members
101
cannot be firmly assembled to the case
1
. Therefore, the cost is increased and the yield is reduced.
It is the object of the invention to provide a battery stage module, which has simple structure and easy assembling.
In one aspect of the invention, two conductive elements contacting the poles of the battery is assembled on a battery stage in advance to form a battery stage module. The conductive elements are also in contact with contacts on a circuit board when the battery stage module is assembled to the circuit board.
In another of the invention, each conductive element comprises a first spring and a second spring formed by bending a metal wire. The first spring is assembled to two lengthwise ends of a battery chamber to touch the poles of the battery. The second spring is arranged beside the jumper contacts of the circuit board. The second spring is in contact with the jumper contacts of the circuit board by a clamping means.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
