## Background
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.

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 10a, a second case 11a, a spacer 12a, a curled reed 13a, a conductive wire 14a and a check body 15a. The spacer 12a, curled reed 13a, conductive wire 14a and check wheel 15a are arranged within the first case 10a and the second case 11a. Two ends of the conductive wire 14a are connected to respective connectors 16a. Two ends of the conductive wire 15a are protruded out of the first case 10a and the second case 11a. Thereby, the two connectors are arranged outsides. By the power stored within the curled reed 13a, the conductive wire 14a is elastically stored within the first case 10a and the second case 11a for providing a telescopic conductive wire 14a. Moreover, by the two connectors 16a, 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 10a and the second case 11a. The check wheel 15a may be rotarily adjusted for properly tightening the curled reed 13a so as to provide a proper elasticity to the curled reed. Thus, two ends of the conductive wire 14a may be elastically stored within the cases 10a and 11a. A plurality of check bodies 17a is protruded from the check wheel 15a and wedge shape grooves (not shown) are installed within the first case 10a and the second case 11a. By the check bodies 17a and the wedge shape groove to form as a check structure, the check wheel 15a only rotates unidirectionally along the direction of tightening the curled reed 13a in order to prevent that the curled reed 13a to release power to push the check wheel 15a to rotate backwards to that the curled reed 13a 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 15a is very complex. Thus, it is very difficult to be assembled and needs many labor hour. Also, the cost is increased.

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.

With reference now to FIGS. 2.about.5, an improved structure of a communication line connecting box of the present invention is illustrated. The improved structure of a communication line connecting box includes a first case 10, a second case 20, a spacer 30, a curled reed 41, and a conductive wire 50. The first case 10 is a round hollow case. One side thereof has an opening. The center within the first case 10 is formed with an axle body 11. The round periphery of the first case 10 is installed with a first through hole 12 and a second through hole 13. The opening of the first case 10 is integrally formed with a buckling body 14 and a plurality of check bodies 15.

The second case 20 is a round hollow case. One side thereof has an opening. The center of the second case 20 is installed with an axle hole 21. A buckling groove 22 is integrally formed on the opening of the second case 20 and a plurality of spaced wedge shape grooves 23 are installed. Inside the second case 20 is further installed with a gap 24. The second case 20 is installed with respect to the first case 10.

The spacer 30 is a circular plate and is installed between the first case 10 and the second case 20. One the center of each side of the spacer is protruded with a sleeve 31 (as shown in FIGS. 6 and 7) and an axle body 32. A conductive wire pillar 33 is formed on the periphery of the spacer 31. A gap 34 is formed on the axle body 32.

The curled reed 40 is disposed between the spacer 30 and the second case 20. The curled reed 40 has an inner hook 41 and an outer hook 42. The inner hook 41 of the curled reed 40 is embedded into the gap 34 of the spacer 30. The outer hook 42 of the curled reed 40 is embedded into the gap 24 of the second case 20. The axle body 32 of the spacer 30 matches with the axle hole 21 of the second case (as shown in FIG. 6) so that one side of the spacer 30 can be pivotally connected to the second case 20.

The conductive wire 50 is installed between the spacer 30 and the first case 10. The conductive wire 50 is folded in half and then is curled. The folded portion 51 covers the conductive wire pillar 33 of the spacer 30 so that the conductive wire 50 can be positioned on one side of the spacer 30. The sleeve 31 of the spacer 30 covers the axle body 11 of the first case (as shown in FIG. 6) so that another side of the spacer 30 is pivotally connected to the first case 10. The two ends of the conductive wire 50 are penetrated outwards through the first through hole 12 and the second through hole 13 of the first case. Therefore, two connectors 52 is arranged on the outside.

After the spacer 30, curled reed 40 and conductive wire 50 are assembled inside the first case 10 and second case 20, the buckling body 14 of the first case 10 and the buckling groove 22 of the second case 20 are connected with each other. Then they are combined by high frequency adhesion or thermal welding. Of course, the first case 10 and second case 20 can be combined by screwing or other ways. By the aforementioned structure, a an improved structure of a communication line connecting box according to the present invention is formed.

In the present invention, by the function of the curled reed 40, the conductive wire 50 can be curled so as to be stored within the first case 10 and the second case 20 so as to provide a telescopic conductive wire 50. Then, two connectors 52 is further used to be connected with a communication source and a information equipment.

Referring now to FIGS. 8 and 9, a check structure is formed by the combination of the check bodies 15 and the wedge shape grooves 23. Therefore, the first case 10 and the second case 20 only rotate unidirectionally for properly rotating the curled reed 40 so as to provide a proper elasticity to the curled reed 40. Thus, two ends of the conductive wire 50 is elasticity stored within the cases 10 and 20. As shown in FIGS. 4 and 5, as the curled reed 40 releases the power for pushing the first case 10 and the second case 20 to rotate in another direction. The check body 15 will buckle in the check grooves 23 to prevent that the first case 10 and second case 20 can not rotate in that direction so that the curled reed 40 is avoided to become loose.

With reference to FIG. 10, a plurality of wedge shape grooves 16 may be further installed on the first case 10, and a plurality of check bodies 25 may be further installed on the second case 20, then a check structure is formed by the matching of the wedge shape grooves 16 and the check bodies 15.

In the present invention, the check structure is directly and integrally formed on the first case 10 and the second case 20. As a result, a prior art check wheel is not employed. Thus, the whole structure is simplified greatly and the present invention can be assembled easily so that labor time and cost are reduced effectively.

Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
