Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of connecting a self-fusing tape to a required electric wire by an indirect hot wire method when connecting a bypass cable. The present invention relates to a live wire tape winding tool used for winding. 2. Description of the Related Art Conventionally, for example, when performing repair work or the like on an overhead distribution line, a covered wire at a repair location is peeled with a peeling tool, and both ends of the peeled wire are connected via bypass devices. By connecting the required bypass line, the required construction will be performed in an uninterrupted state. After completion of required works such as repair work, the self-fusing tape is spirally wound around the exfoliated electric wire to perform insulation waterproofing after removing the bypass wire. [0003] As a tool for winding such a self-fusing tape around a peeled wire, a hollow rotary body having an opening and closing portion for wire insertion is rotatably mounted on a required case body via a drive mechanism. At the same time, a tape mounting arm and a swinging arm with a biasing spring are attached to the hollow rotating body via a bracket, and a tip of the swinging arm is attached to the tip of the swinging arm. It is known that a friction roller is pivotally mounted (see Japanese Utility Model Laid-Open No. 3-30713). In such a tape winding tool, after a required electric wire is inserted into the hollow rotary body through the opening / closing section, the hollow rotary body is rotated by a driving mechanism, and is mounted on a tape mounting arm. The winding operation is performed while the back tension is applied to the self-fusing tape by a friction roller. [0004] However, in the tape winding tool having the above-described structure, the friction roller is urged by the urging spring via the swing arm. Since the back tension is applied to the self-fusing tape, the strength of the back tension is inevitably different depending on the winding outer diameter of the self-fusing tape.
For this reason, the wound outer diameter of the mounted self-fusing tape is large,
That is, in the early stage of the winding operation, the back tension is very strong, but as the winding operation progresses, the back tension gradually weakens in conjunction with the self-fusing tape in which the outer diameter of the winding gradually decreases, The winding work must always be performed with non-uniform back tension, and as a result, the winding on the peeled wire is insufficient, which is likely to cause electrical problems in terms of insulation and waterproofness. It is. In addition, since the conventional winding tool does not have a separator winding function, the separation type self-fusing tape which has been widely used recently, that is, the adhesive surface of the self-fusing tape. It is impossible to cope with the case where the separator is detachably attached to the above. The present invention has been made to solve the conventional problems, and performs a winding operation reliably while giving a stable and constant tension to a separate type self-fusing tape. Another object of the present invention is to provide a live wire tape winding tool capable of effectively exhibiting an excellent winding function in terms of electrical characteristics such as water resistance and waterproofness. That is, the present invention provides a hollow rotator 1 having an opening 3 for inserting an electric wire, which is rotatable by an insulating operating rod 2, and a tip side of the hollow rotator 1.

After the tape 33 is mounted on the tape mounting shaft 10, the tip thereof is inserted between the guide roller 18 and the pressure roller 20, and the knob 21 is turned to rotate the operation shaft 22, thereby obtaining the gear. The guide roller 18 and the separator winding roller 15 are manually and synchronously rotated via the mechanism 23. Then, the separator type self-fusing tape 33 is sent out along the rotating guide roller 18 while being pressed by the pressure roller 20, thereby separating the separator 34b to remove the separator. -Attach the stopper piece 17 of the roller 15 and lightly hook the self-fusing tape main body 34a to the tape pressing claw 9 of the contact member 8.

Begins to wrap in a spiral. At this time, a separate type self-fusion tape 3
3 is pressed by the pressure roller 20, so that a constant tension is always applied at the time of winding,
The winding can be performed reliably. Further, the guide roller 18 is rotated by rewinding the separator type self-fusing tape 33 accompanying the winding, and the separator winding roller 15 is automatically rotated via the gear mechanism 23. Then, the separator 34b which is sequentially peeled off by winding is wound up. In particular, since the separator take-up roller 15 is formed slightly larger than the outer diameter of the guide roller 18, the separated separator 3 is removed.
4b can be reliably wound up while applying tension thereto. Further, even when the winding of the separator 34b becomes large and a tension higher than a predetermined level is generated, the separator winding roller 15 can be used. The winding operation can be always performed smoothly by operating the idle rotation as appropriate. In the same manner, the operation rod 2 is successively retracted and operated, and the hollow rotary body 1 is rotated to wind the self-fusing tape body 34a around the peeled wire A in a spiral shape. When the winding is completed, the separate type self-fusing tape 34 is cut with a tape cutter, and then the winding end is pressed with a yoke to complete the winding operation. In the above embodiment, the gear mechanism 23 is shown as the transmission mechanism.
