Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a protective cover device for an unwrap tool used when removing a signal wire from a terminal pin of a terminal board.

[0002]

[Prior art]

 A wrapping tool is used to attach the signal wire to the terminal pin of the terminal board, and an unwrap tool is used to remove it. FIG. 3 is a perspective view of the terminal board, and FIG. 4 is a cross-sectional view of the terminal board in which signal lines are wrapped around the terminal pins. As shown in FIG. 3, the terminal board is made by implanting a large number (for example, 8 × 25 = 200) of terminal pins 16 on a board 15 made of a glass epoxy substrate or the like.

As shown in FIG. 4, the terminal pin 16 is planted so as to penetrate the board 15. The signal line 9a is provided on one side of the terminal pin and the signal line 9b is provided on the other side thereof. Are connected by wrapping. The signal lines are covered with vinyl or polyethylene, etc. When connecting to the terminal pins, remove the insulating cover from the connection and then wrap (wrap) with a wrapping tool. For example, in the case of a terminal board used in a subscriber line drawer of a telephone station, the signal line 9a connected to one side of the terminal board is a line drawn from an exchange (subscriber exchange) in the telephone station. The signal line 9b connected to the other side is a line that is directly led to the subscriber's facility as a subscriber line.

By the way, sometimes it is necessary to remove the signal line 9b from the terminal board or replace it with another terminal pin. In that case, the signal line to be removed or replaced must be removed from the terminal pin using an unwrap tool. FIG. 5 is a perspective view of the unwrap tool 10 used for this purpose. As shown in the figure, the unwrap tool 10 is provided with tool parts 12 for unwrapping at both ends of a gripping part 11.

The tool parts at both ends are formed to have different diameters so that unwrapping can be performed from terminal pins having different diameters. Usually, one tool part is covered with a cap 13. The tool portion is formed of a cylindrical metal, and a screw valley having a little more than one turn is carved on the outer peripheral surface of the tool tip portion 12a. Further, a sharp claw 12b is formed at the most distal end of the tool portion 12.

In removing the signal line, first, the tool tip portion 12a is put on the corresponding terminal pin, and the claw 12b is put on the tip portion of the signal line to peel off the signal line tip portion from the terminal pin. Then, when the unwrap tool is pressed and rotated slowly, the signal wire is peeled off from the terminal pin and wound up along the thread valley formed on the outer periphery of the tool tip portion 12a of the unwrap tool.

Therefore, even when the signal line is removed, the other terminal pins remain active. For example, when the signal line is removed from the terminal pin 16a in FIG. 4, the terminal pins around it are in the active state. Therefore, if the bare wire of the removed signal line comes into contact with another terminal pin, it will lead to a circuit accident.Therefore, it is necessary to take protective measures (so-called curing) in advance in order to prevent contact accidents when removing. . Conventionally, for example, when the signal line is removed from the terminal pin 16a shown in FIG. 4, the vinyl tube 14 is put on the terminal pin around the signal line for curing.

[0008]

[Problems to be solved by the device]

 In the method of covering with the vinyl tube described above, the terminal plate is often placed in a place where the scaffolding is not good, which makes the work difficult and takes a long time. In addition, the vinyl tube may come off during the work of removing the signal line (the terminal pin on which the signal line to be removed is not always facing upward as shown in Fig. 4), and it may be necessary to perform curing. Even if I went there, I could not eliminate contact accidents. The present invention has been made in view of such a situation, and an object thereof is to surely prevent a contact accident of a removed signal line without performing curing. Is.

[0009]

[Means for Solving the Problems]

 An unwrap tool protection cover device according to the present invention for achieving the above object comprises a cylindrical spring accommodating member (1) accommodating a coil spring (7) and one end portion fixed to the spring accommodating member. A cylindrical stopper member (2) that serves as a stopper for the coil spring, and a protrusion that engages with a protrusion formed on the inner surface of the tip of the spring accommodating member are formed on the outer peripheral portion of the coil spring. A cylindrical slide member (3) held by the spring housing member so that a part of the unwrapping member can slide in the spring housing member against the urging force of the unwrapping member. It is characterized in that the tool (10) can be housed inside so that the tool part (12) is located on the slide part and can be fixed to the spring housing member.

[Embodiment of device]

 Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which an unwrap tool according to an embodiment of the present invention is accommodated. As shown in FIG. 1, most of the unwrap tool other than the part covered with the cap 13 is housed in the protective cover device of this embodiment. The stopper member 2 is fixed to the spring housing member 1 by a screw (hexagonal groove screw) 5. The grip portion of the unwrap tool is also fixed to the spring housing member 1 and the stopper member 2 by the screw 5.

A slide member 3 is slidably held on the side of the spring housing member 1 opposite to the side where the stopper member 2 is attached. The slide member 3 includes a slide member body 3a and a transparent cover 3b adhered to the slide member body 3a. The unwrap tool is usually fixed such that the tool tip portion 12a is located inside the transparent cover 3b. The slide member 3 can slide in the spring housing member 1 against the spring force of the coil spring in the state where the unwrap tool is housed.

FIG. 2 is a sectional view of the unwrap tool protection cover device of this embodiment. The stopper member 2 is provided with four screw holes 6, and the spring housing member 1 is provided with two screw holes 6. A step is provided on the outer periphery of the tip end portion of the stopper member, and that portion is inserted into the spring accommodating member 1. By screwing screws into the screw holes 6 of these members with the unwrap tool 10 inserted, the gripping portion 11 of the unwrap tool can be fixed to the present protective cover device, and the stopper member 2 can be used as the spring accommodating member. It is fixed at 1.

A protrusion is formed on the inner peripheral portion of the tip of the spring housing member 1, and a protrusion is also formed on the outer peripheral portion of the tip portion of the slide member body 3 a. It is designed so that the attached stopper member does not fall out. A coil spring 7 is mounted in the spring accommodating member 1, and one end of the coil spring 7 abutting on the end of the stopper member 2 abuts on one end of the slide member 3 to project from the slide member 3.
