ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an improved structure of a communication line connecting box, and especially to a communication ling connecting box for connecting between a communication box and related equipment. The communication line connecting box has a telescopic conductive wire and a simple structure, can be easily assembled and thus is made with a lower cost.
BACKGROUND OF THE INVENTION
Prior art communication line connecting box is connected between a communication source and related information equipment and has a telescopic conductive wire. As shown in
FIG. 1
, the communication line connecting box includes a first case
10
a
, a second case
11
a
, a spacer
12
a
, a curled reed
13
a
, a conductive wire
14
a
and a check body
15
a
. The spacer
12
a
, curled reed
13
a
, conductive wire
14
a
and check wheel
15
a
are arranged within the first case
10
a
and the second case
11
a
. Two ends of the conductive wire
14
a
are connected to respective connectors
16
a
. Two ends of the conductive wire
15
a
are protruded out of the first case
10
a
and the second case
11
a
. Thereby, the two connectors are arranged outsides. By the power stored within the curled reed
13
a
, the conductive wire
14
a
is elastically stored within the first case
10
a
and the second case
11
a
for providing a telescopic conductive wire
14
a
. Moreover, by the two connectors
16
a
, the conductive wire is connected to a communication source or an information equipment.
A part of the check body may protrude out of the conductive wire
10
a
and the second case
11
a
. The check wheel
15
a
may be rotarily adjusted for properly tightening the curled reed
13
a
so as to provide a proper elasticity to the curled reed. Thus, two ends of the conductive wire
14
a
may be elastically stored within the cases
10
a
and
11
a
. A plurality of check bodies
17
a
is protruded from the check wheel
15
a
and wedge shape grooves (not shown) are installed within the first case
10
a
and the second case
11
a
. By the check bodies
17
a
and the wedge shape groove to form as a check structure, the check wheel
15
a
only rotates unidirectionally along the direction of tightening the curled reed
13
a
in order to prevent that the curled reed
13
a
to release power to push the check wheel
15
a
to rotate backwards to that the curled reed
13
a
will become loose. The aforementioned structure may refer to U.S. Pat. No. 5,230,481.
However, in the prior art communication line connecting box, the installation of the check wheel
15
a
is very complex. Thus, it is very difficult to be assembled and needs many labor hour. Also, the cost is increased.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an improved structure of a communication line connecting box comprising a first case, a second case, a spacer, a curled reed, and a conductive wire. The check structure is integrally formed on the first case and the second case. The prior art check wheel is unnecessary in the present invention. Thus, the whole structure can be simplified greatly. Moreover, the assembly thereof is easy and the labor time is saved effectively and therefore, cost is reduced.
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.
