Length-adjustable cable tie capable of eliminating the waste thereof

Abstract

Disclosed is a cable tie used for the purpose of tying and arranging cables, and it is formed of a belt part 310 which is stored in the shape of a reel 370 at usual time and is unwound for tying cables when needed, and engaging head parts 320 and 420 fixing and preventing the belt part, which has tied the cables, from loosening. The present invention makes it possible to conveniently arrange the cables without using a special tool, and over consumption of the belt part can be prevented as compared to a conventional cable tie 100 in which the leftovers of the belt part 130 after it is cut are discarded. In case of the conventional cable tie 100, the cable tie 100 should be used depending on the thickness of the cables to be arranged; however in the present invention, the belt part 310 is unwound as much as the needed length long enough to tie the cables, and the cables are tied, and the belt part 310 is tightened and cut, and the remaining leftovers are wound on the reel 370 and are stored. So, it does not need to carry various types of cable ties during the cable arranging work, and the leftovers of the belt part 310 can be effectively stored.

1 . A cable tie which includes a belt part  310  surrounding electric cables or ordinary cables, and engaging head parts  320  and  420  fixing the belt part so that the electric cables or ordinary cables remains surrounded by the belt part, comprising:
 toothed blades  323  and  324  which are arranged in different directions at both sides of the belt part, 
 the start inlet of the belt part surrounding the electric cables or ordinary cables via the start inlet  329  of the engaging head part and being inserted into an end inlet  331  of the engaging head part. 
 
     
     
         2 . A cable tie according to  claim 1 , wherein said belt part is fixed so that the belt part inserted in the end inlet does reliably fits a volume-reduced space of the engaging head part and does not escape from it when the belt part is inserted into the end inlet of the engaging head part after the belt part surrounds the cables to be arranged as the empty space in the interior of the engaging head part is reduced, the belt part having passed through the engaging head part in the interior of the engaging head part. 
     
     
         3 . A cable tie according to  claim 1 , wherein said engaging head parts  320  and  420  are separate from the belt part  310 . 
     
     
         4 . A cable tie according to  claim 1 , wherein said toothed blades of both sides of the belt part are formed in protruded shapes. 
     
     
         5 . A cable tie according to  claim 1 , wherein said toothed blades of both sides of the belt part are formed in concaved shapes. 
     
     
         6 . A cable tie according to  claim 1 , wherein a toothed blade of one side of the belt part is formed in a protruded shape, and a toothed blade of the other side of the belt part is formed in a concaved shape. 
     
     
         7 . A cable tie according to  claim 1 , wherein the start inlet and the end inlet of the engaging head part are placed on the facing surfaces of the engaging head part. 
     
     
         8 . A cable tie according to  claim 1 , wherein the start inlet and the end inlet of the engaging head part are placed on the same surfaces of the engaging head part. 
     
     
         9 . A cable tie according to  claim 7 , wherein the toothed blades of the belt part inserted in the end inlet  331  of the engaging head part is caught and is not withdrawn by means of the toothed blades  321  formed at the inner side of the engaging head part, and the belt part inserted in the end inlet of the engaging head part comes into contact with the belt part, which has passed via the start inlet  329  of the engaging head part, in the interior of the engaging head part, and when the toothed blades are engaged with each other on the contacting surfaces of two contacting surfaces, the belt can escape from the engaging head part in the opposite direction that the belt part has passed through the engaging head part via the start inlet, and in the engaged state, the belt part no more passes through the engaging head part via the start inlet in the direction that it has passed. 
     
     
         10 . A cable tie according to  claim 8 , wherein in the interior of the engaging head part, a separation plates  425  separates a space accommodating the belt part passes through the start inlet of the engaging head part and a space accommodating the belt part which is inserted again via the end inlet of the engaging head part, and at the separation plate are formed toothed blades which hold the belt part inserted in the end inlet of the engaging head part for it no to escape, and the separation plate is configured in such a way that the side where the toothed blade is not formed is fixed at a body of the engaging head part, and the side where the toothed blades are formed is bent with a certain elasticity, and when the belt part is inserted into the end inlet of the engaging head part, the portion of the separation pate at the side of the toothed blade is pushed in a bent state into the space of the start inlet of the engaging head part with the aid of the height of the shoulder of the toothed blade formed at the separation plate and the thickness of the inserted belt part, and the engaging head part makes the belt part pass via the start inlet of the engaging head part when the belt part is not inserted into the end inlet of the engaging head part, and when the belt part is inserted into the end inlet of the engaging head part, the toothed blade formed at the separation plate of the engaging head part holds the toothed blade formed at the contacting surface of the belt part which has been inserted into the end inlet of the engaging head part for thereby preventing the belt part from escaping in the opposite direction that it is inserted into the end inlet of the engaging head part, and when the belt part is inserted into the end inlet of the engaging head part, as described above the separation plate is pushed toward the passing through space of the belt in the engaging head part by means of the height of the toothed blades of the separation plate of the engaging head part and the thickness of the belt part inserted into the end inlet of the engaging head part, and consequently, the bent separation plate pressurizes the belt part which passes through the start inlet of the engaging head part, and the toothed blades of the passing belt part is engaged with the corner of the separation plate, so the belt part passing through the start inlet of the engaging head part can be pulled and escape in the opposite direction that the engaging head part passes through, but can no longer pass. 
     
     
         11 . A cable tie according to  claim 9 , wherein at said engaging head part is formed a stopper wall for the purpose of preventing the belt part inserted in the end inlet of the engaging head part from protruding and escaping from the engaging head part. 
     
     
         12 . A cable tie according to  claim 10 , wherein at said engaging head part is formed a stopper wall for the purpose of preventing the belt part inserted in the end inlet of the engaging head part from protruding and escaping from the engaging head part. 
     
     
         13 . A cable tie, comprising:
 an engaging head part  320  fixing a belt part  310  which serve to tie a plurality of cables, and   said engaging head part including in its interior:   a through space through which the belt part passes; and   a space in which the start end portion  327  of the belt part surrounding the cables to be tied and having passed via the through space is folded with the passing belt part, and   an inner toothed blade  321  being formed at an inner surface of the engaging head part for the purpose of fixing the start end of the inserted belt part and preventing it from escaping.   
     
     
         14 . A cable tie, comprising:
 an engaging head part  420  fixing a belt part  310  which serve to tie a plurality of cables, and   said engaging head part  420  including in its interior:   a through space through which the belt part passes; and   a separation space  425  which is formed along the through space, and   a toothed blade  426  being formed at one side end of the separation plate.   
     
     
         15 . A cable tie according to  claim 14 , wherein said separation plate  425  is connected to only a partial portion of the inner surface of the engaging head part  420  and has a certain elasticity.
