ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention generally relates to an adapter for a portable telephone, and more particularly to an adapter for a portable telephone which can be used as a mobile telephone in a vehicle.
(2) Description of the Related Art
In a case where a portable telephone is used as a mobile telephone in a vehicle, it is important to be capable of simply operating the portable telephone.
A conventional adapter for a portable telephone is shown in FIG.
1
. Referring to
FIG. 1
, an adapter
10
has an adapter body
11
and a connector
13
. The connector is mounted at an end of a curl cord
12
extending from the adapter body
11
. The adapter body
11
is installed in the vehicle
14
. The adapter body
11
is connected with a cord
16
extending from an antenna
15
provided on the vehicle
14
and wires
18
extending from a battery
17
provided in the vehicle
14
.
A user of the portable telephone
20
gets into the vehicle
14
and connects the connector
13
at the end of the curl cord
12
to a socket
21
formed at an end surface of the portable telephone
20
as shown by an arrow A in FIG.
1
. The user then sets the portable telephone
20
on a telephone setting portion
19
of the adapter body
11
as shown by an arrow B in FIG.
1
.
In a state where the portable telephone
20
is connected to the adapter
10
as described above, the portable telephone
20
can be used as a mobile telephone in the vehicle
14
. In this state, a battery
22
of the portable telephone
20
is charged by the battery
17
in the vehicle
17
.
To make the portable telephone
20
capable of use as the mobile telephone in the vehicle
14
, it is necessary for the user to carry out at least two operations: a connecting operation for connecting the connector
13
to the socket
21
of the portable telephone
20
(see the arrow A) and a setting operation for setting the portable telephone
20
on the adapter body
11
(see the arrow B). Specifically, since the connector
13
is small, the connecting operation is awkward.
In addition, the curl cord
12
is formed of a coaxial cable
23
which is expensive. Thus, the production costs of the adapter
10
for the portable telephone
20
is increased.
SUMMARY OF THE INVENTION
Accordingly, a general object of the present invention is to provide a novel and useful adapter for a portable telephone in which the disadvantages of the aforementioned prior art are eliminated.
A more specific object of the present invention is to provide an adapter to which a portable telephone can be connected by simple operations.
Another object of the present invention is to provide an adapter in which the production costs can be decreased.
The above objects of the present invention are achieved by an adapter in which a portable telephone having a first connecting unit including terminals connected to electric terminals therein is receivable, the adapter comprising: an adapter body having a concave portion in which the portable telephone is receivable; a second connecting unit provided in the adapter body so as to be exposed to the concave portion, the second connecting unit having terminals connected to predetermined electric units including at least an antenna, the second connecting unit being connectable to the first connecting unit of the portable telephone; and a clamping mechanism for clamping the portable telephone received in the concave portion of the adapter body in a state where the second connecting unit is connected to the first connecting unit of the portable telephone so that the terminals of the second connecting unit are in contact with the terminals of the first connecting unit of the portable telephone.
According to the present invention, when the portable telephone is set in the adapter body and clamped by the clamping mechanism, the portable telephone and adapter are electrically connected with each other via the first and second connecting units. Thus, due to simple operations, the portable telephone and the adapter can be electrically connected with each other.
In addition, to electrically connect the adapter and the portable telephone, the curl cord is not needed. Thus, the production cost of the adapter can be decreased.
