Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment / detachment rod for connecting a power cable.

[0002]

[Prior art]

 FIG. 3 is an explanatory view of a conventional attachment / detachment operation rod of a power cable connecting portion. In FIG. 3, 1 is a hook, 2 is a spacer, 3 is a clamp, 4 is an insulating rod, and 5 is a protrusion. The attachment / detachment operation rod is a hook 1 that engages with a hook 7 fixed to the power cable connection portion 6 at one end of the insulation rod 4, an annular spacer 2 for holding the attachment / detachment operation rod itself at the cable end portion, and an insulation of the spacer 2. It is composed of an annular tightening fitting 3 fixed by a protrusion 5 of a rod 4. The fastening fitting 3 is provided with a groove that is engaged with the protrusion 5 and is inclined so as to press the fastening fitting 3 against the spacer 2 by turning.

FIG. 4 is an explanatory view of a structure when a conventional attachment / detachment operation rod is attached to the power cable connecting portion 6. In FIG. 4, 6 is a power cable connecting portion, and 7 is a hook. This attachment / detachment rod sticks the hook 1 to the hook 7 of the power cable connecting portion 6, and fixes the hook 1 by sliding the spacer 2 to the left, and the fastening metal fitting 3 is slid to the left so that the spacer 2 does not come off. , Is rotated upward and hooked on the protrusion 5, and fixed by frictional resistance between the protrusion 5 and the groove of the fastening member 3.

[0004]

[Problems to be solved by the device]

 Conventionally, the tip of the attachment / detachment operation rod has a tightening portion to the power cable connecting portion 6, and the attachment / detachment operation rod is fixed by the friction resistance between the protrusion and the groove by the metal fastening member. Therefore, in the unlikely event that the grounding wire of the connection part is disconnected and the external shield of the connection part floats above the ground and a voltage is induced in the external shield, an electric shock to the human body is generated through the metal fastening member. There was a danger of.

An object of the present invention is to provide a detachable operating rod for a power cable connecting portion, which enhances safety and can be operated at hand.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the attachment / detachment operation rod of the power cable connection portion of the present invention has a cylindrical holder portion for fixing the attachment / detachment hook of the power cable connection portion, which is fixed to one end of the insulating rod. A vertical groove having a width larger than the outer diameter of the rope hooking portion of the hook in the center of the end face, and an angle of 45 ° with the vertical groove communicating with the vertical groove and extending from both ends of the vertical groove to both sides. Is provided, and a slope is provided in the turning direction on the end face side surface of the cut groove.

[0007]

[Action]

 To connect and disconnect the power cable connection part, apply the vertical groove of the attachment / detachment operation rod to the hook of the connection part, insert the hook along the vertical groove, and rotate the insulating rod 45 ° clockwise to make the hook slope. Slide it into the cut groove, and then pull or press the insulating rod and rotate it 45 degrees to the right to remove it, so the holder will not be touched, and there is no danger of electric shock to the human body. You can eliminate the sex.

【Example】

 Hereinafter, the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view of an embodiment of an attachment / detachment operating rod of a power cable connecting portion according to the present invention. In FIG. 1, 8 is a holder part. FIG. 2 is an explanatory view of an embodiment of an attachment / detachment operating rod of a power cable connecting portion of the present invention. In FIGS. 1 and 2, 9 is a vertical groove, 10 is a cut groove, and 11 is a slope. A cylindrical holder portion 8 is provided at one end of the insulating rod 4, and a vertical groove 9 is formed in the center of the end face of the insulating rod 4 and a cut groove 10 having a quarter circumference is connected to both side surfaces of the holder portion 8. 2 are provided on the opposite side, and a slop 11 is provided on the end face side of the cut groove 10. The widths of the vertical groove 9 and the cut groove 10 are made slightly larger than the outer shape of the hook 7. To attach and detach the power cable connecting portion 6, apply the vertical groove 9 of the attachment / detachment operation rod to the hook 7 of the connecting portion, insert the hook 7 along the vertical groove 9, and rotate the insulating rod 4 45 ° to the right so that the slope 11 is removed. It can be carried out by sliding it into the cut groove 10 and then pulling or pressing the insulating rod 4 and rotating it 45 ° to the right.

[0010]

[Effect of device]

 According to the present invention, it is possible to attach / detach the power cable connecting portion without touching the holder portion during the attaching / detaching operation of the power cable connecting portion, thereby eliminating the risk of electric shock to the human body.
