ABSTRACT:
PRIORITY
This application claims priority to an application entitled “Battery Pack Locking Apparatus for a Mobile Telephone” filed in the Korean Industrial Property Office on Jan. 11, 2000 and assigned Serial No. 2000-1163, the contents of which are hereby incorporated by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a battery pack locking apparatus for a mobile telephone, and in particular, to a battery pack locking apparatus in which a locker is operable with its own mechanical structure without using separate elastic means.
2. Description of the Related Art
In general, a mobile terminal such as a mobile telephone has a battery pack detachably mounted on the rear side of its body as a power source. The battery pack is locked by a locking apparatus mounted on the body of the mobile telephone, and at least one guide rib is formed on the body to guide the battery pack.
In addition, the battery pack has electrodes formed on the inner and outer surfaces of its lower portion. The electrodes formed on the inner surface of the battery pack are so structured as to contact the connection terminals formed on the rear surface of the body of the mobile telephone. Further, the electrodes formed on the outer surface of the battery pack are so structured as to contact the connection terminals of a charger during charge.
FIG. 1
is a perspective view illustrating the rear side of a general mobile telephone, with a battery pack detached from a body of the mobile telephone.
FIG. 2
is a partial plane view illustrating the battery pack locking apparatus of FIG.
1
.
Referring to
FIGS. 1 and 2
, the mobile telephone includes a body
100
comprised of an upper casing frame
101
and a lower casing frame
102
, and a battery pack
200
detachably mounted on the rear side of the body
100
. The lower casing frame
102
has a plane surface
103
formed on its rear side, and the plane surface
103
has connection terminals protuberantly formed at one end and a locking apparatus
105
mounted on another end, for fixedly attaching the battery pack
200
to the lower casing frame
102
. In addition, the plane surface
103
has guide ribs
104
formed on its both sides to guide the battery pack
200
to the locking apparatus
105
, and the battery pack
200
also has guide ribs
204
formed on its both sides to be combined with their associated guide ribs
104
on the plane surface
103
. In such a mobile telephone, the battery pack
200
is attached to and detached from the lower casing frame
102
in the direction “B”, and a locker
105
for locking the battery pack
200
operates in the direction “A”.
FIG. 3
is a cross-sectional view illustrating a conventional battery pack locking apparatus for the mobile telephone.
Referring to
FIG. 3
, a locker
105
includes a hook (
106
of
FIG. 1
) formed to be hooked at a hooking groove (not shown) formed on the front side of the battery pack
200
, at least one guide rib
107
mounted on the lower casing frame
102
to guide the locker
105
perpendicularly, and a spring pin
108
for supporting a spring
109
, the spring pin
108
extending downward from the center of the locker
105
. The guide rib
107
has a hook
107
a
formed at one end to be hooked at a hooking member
102
a
formed on the lower casing frame
102
, to thereby prevent the locker
105
from being detached from the lower casing frame
102
during its up-and-down movement. The spring pin
108
is mounted on the lower surface of the locker
105
such that it should freely pass through a guide hole
102
b
formed in the lower casing frame
102
, to thereby prevent interference with the up-and-down movement of the locker
105
.
However, the conventional battery pack locking apparatus uses the separate spring for the elastic means. Use of the spring unavoidably increases the number of assembling processes, making the assembling process complicated.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a battery pack locking apparatus for a mobile telephone, which has a structure with a reduced number of assembling processes.
It is another object of the present invention to provide a battery pack locking apparatus for a mobile telephone, in which a locker is operable with its own mechanical structure without using a separate element.
To achieve the above and other objects, there is provided a battery pack locking apparatus for a mobile telephone. The battery pack locking apparatus includes a locker up-and down movably mounted on a lower casing frame of the mobile telephone, and an elastic member formed on a lower surface of the locker to provide a restitution force to the locker.
Preferably, the elastic member is a zigzag tension rib, which is formed extending downward from the lower surface of the locker such that a free end of the tension rib should be pressingly in contact with to the lower casing frame.
Preferably, the lower casing frame has a plane surface with which the free end of the tension rib pressingly contacts.
