ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a micro-type communication wire winder which has a simple structure and can be produced easily and conveniently. A desired length of a communication wire can be pulled from the winder then fixed. The communication wire may thus be maintained neatly, without being in tension.
BACKGROUND OF THE INVENTION
With the current prevalence of computers, modems, telephones, facsimile machines, and the like, communication wires are required to connect different devices. In order to prevent the communication wire from being too long or too short, various wire winders have been developed for winding such communication wires. The basic structure of known wire winders includes a housing, a rotary disk, a spiral screen, and a communication wire. The spiral screen pulls the rotary disk so that the communication wire wound around the rotary disk is biased by a restoring force. Since the communication wire must connect with two communication devices, the connection and conduction structure of the communication wire in the wire winder has many different designs. For example, a plurality of concentric and unequal diameter conductive rings are disposed on the rotary disk, while a plurality of conductive elastic pieces or steel balls are arranged on another rotary disc so that even during rotation, electric connection is maintained. These prior art designs require many components and a complicated structure which makes assembly more difficult, and makes it more likely that components will be arranged ineffectively. Moreover, since the spiral spring is often not arranged properly, the volume of the wound wire may be increased, heightening inconvenience in use and storage. Also, after the communication wire is pulled out from the prior art wire winder, it will be in tension due to the elastic force of the spiral spring and thus a proper length of the wire may not be left unwound. This proves quite troublesome to a user. Therefore, there is a need for a micro-type communication wire winder which addresses such prior art defects.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a micro-type communication wire winder. The wire winder has a simple structure and can be produced easily and conveniently. A desired length of a communication wire can be pulled out and fixed at that length. A communication wire is maintained in a simple untensioned configuration.
In order to achieve the aforesaid object, a micro-type communication wire winder is disclosed. A rotary disk is pivotally installed in a receiving groove of a housing, and one surface thereof is installed with an axle bushing and an outer circular cover with slots for fixing and winding a communication wire. Another surface is installed with a ring protrusion for receiving and engaging a spiral spring or receiving the spiral spring in a cavity adjacent to the rotary disk so that the spiral ring can be wound around the protrusion. Thus, the communication wire is biased by a rewinding force. The rim of the rotary disk is further installed with a tilt buckling groove. A buckling piece at the side of the housing obliquely resists against the rim of the rotary disc. Therefore, as the communication wire is pulled out to a predetermined length, the rotary disk can be buckled in the buckling groove by the buckling piece so as to retain the predetermined length. As the buckling piece is pressed, the rotary disc is released and rewound.
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 drawings.
