Description

  The present invention relates to a cord of a USB connector, and more particularly, to a cord reel having at least one terminal and extending and winding the cord by an operation of pulling the cord of the terminal.

  The development of science and technology is steadily progressing, but with the spread of personal computers and the development of 3C (Computer, Consumer Electronics, Communication) electronic devices, various different peripheral devices have appeared, and various new products such as terminals, sockets, transmission lines, etc. Has been released continuously. Currently, USB (Universal Serial Bus), which is a data input interface, has become widespread, and in particular, it is often used by businessmen and travelers by extending terminals of two different standards using transmission lines. ing. However, the handling of transmission lines connecting terminals and sockets with different standards has been a problem.

  In order to solve this problem, a cord reel appeared. In this case, a reel board coupled with a winding spring is arranged in the case, the transmission line is wound around the reel board, and the inner end of the transmission line is connected to the connection line outside the case from the center of the reel board via the contact holding mechanism. Even when the reel board rotates, it continues to be connected to the connection line outside the case. The outer end of the transmission line extends directly out of the case, and the reel board is connected to the localization / recovery mechanism. When the outer end of the transmission line is pulled, the reel board is linked and the take-up spring is extended, and the localization / recovery mechanism positions the reel board and keeps the transmission line extended to an appropriate length outside. For use. After use, the localization / recovery mechanism causes the reel board to wind up the transmission line extending outside the case by the spring force of the take-up spring. Thus, the transmission line is automatically wound on the reel board.

In the case of a commercially available cord reel, if the distance for extending the transmission line is too long, the winding spring is often excessively pulled and damaged, or contact failure is often caused by friction. For this reason, a cord reel that has improved these problems has been demanded.

A first object of the present invention is to provide a cord reel for connecting terminals in which the cord can be extended and wound quickly.
The second object of the present invention is to provide a cord reel for connecting terminals that eliminates noise and can be used smoothly.

  To achieve the above object, the present invention provides a cord reel. The cord reel of the present invention includes a main body 11, a cord reel shaft portion 12, a cord body 17, a guide member 15, and at least one guide operation portion 16. The main body has a shaft body. The cord reel shaft portion 12 is disposed on the shaft body. The cord body 17 has at least one terminal, and a part thereof is wound around the surface of the outer edge of the cord reel shaft portion. The guide member 15 is disposed on the cord reel shaft portion, has a guide groove of a predetermined shape, and has at least one localization housing recess. The guide operating unit 16 is connected to the main body and has at least one guide body, and the guide body is disposed in the guide groove. When the terminal cord is pulled out, the cord reel shaft rotates around the shaft body, and the cord is moved and positioned along the shape of the guide groove at the position where the cord is pulled out for a predetermined length. When located in the recess, the terminal is fixed at a predetermined position.

  In the cord reel of the present invention, when the terminal cord is pulled out, the cord reel shaft portion simultaneously rotates around the shaft body and moves and positions along the shape of the guide groove. Extension and winding can be done quickly. Further, since the guide groove is located on the same plane, noise can be eliminated and the guide groove can be used smoothly.

Embodiments of the present invention will be described below with reference to the drawings. Please refer to FIG. 1 and FIG. FIG. 1 is an exploded perspective view illustrating a cord reel for connecting terminals according to an embodiment of the present invention. FIG. 2 is a perspective view showing a terminal connecting cord reel according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the terminal connecting cord reel 1 of the present invention includes a main body 11, a cord reel shaft portion 12, a cord body 17, a guide member 15, and a guide operating portion 16.
The main body 11 includes a case upper part 111 and a case lower part 112. The case lower portion 112 has a shaft body 113. The cord reel shaft portion 12 is in contact with the case lower portion 112, and the outer edge surface is in a substantially parallel relationship with the extending direction 92 of the shaft body 113. The cord reel shaft portion 12 has a shaft hole 121 through which the shaft body 113 is inserted, and performs a rotational motion 91 with the shaft body 113 as an axis. The main body 11 further has an accommodation recess 114. The accommodating recess 114 has a shape corresponding to the shape of the guide operating portion 16, and the guide operating portion 16 is disposed in the accommodating recess 114. In the present embodiment, the cord body 17 has at least one terminal 18. Further, the cord body 17 is collected by the arrangement portion 19, and the arrangement portion 19 is arranged in the cord reel shaft portion 12. As a result, the cord body 17 is neatly arranged in the cord reel shaft 12 and is wound around the cord reel.

  Please refer to FIG. FIG. 3 is a perspective view showing the guide member 15 of the cord reel for connecting terminals according to the present invention. As shown in FIG. 3, the guide member 15 is disposed on the cord reel shaft portion 12 and has a guide groove 151 having a predetermined shape. In the present embodiment, the guide member 15 has a substantially vertical relationship with the shaft body 113. The guide member 15 has four protruding portions 152 formed by the guide grooves 151. Two sets of the four projecting portions 152 are symmetrical with each other, and two of them have a stereotaxic recess 153, respectively.

  Please refer to FIG. FIG. 4 is a perspective view showing the guide operating part of the present invention. As shown in FIG. 4, the guide operating unit 16 has an L shape and has a long side 161 and a short side 162. The long side 161 and the short side 162 are in a substantially vertical relationship. The guide operating unit 16 further includes at least one guide body 163 on one end of the short side 162. Two guide bodies 163 are arranged in the guide groove 151, and the guide body 163 is guided and moved in the guide groove by the rotation accompanying the pulling operation of the cord reel, and the rotation corresponds to a predetermined cord pulling length. Thus, the two guide actuating portions 16 are correspondingly arranged so as to be positioned in the localization housing recess 153 of the guide member.

  Please refer to FIG. FIG. 5 is a front view showing the connecting operation of the guide operating part and the guide member of the present invention.
