Conventionally, this earthing and short-circuiting device is used to grip the core wire of the distribution line at the clamp part. To install it, it is necessary to strip off the insulation of the distribution line. After removing the instrument, it was necessary to perform insulation treatment such as attaching an insulating cover.

  For this reason, the earthing | grounding short circuit instrument which can be attached, without stripping off the insulation coating of a distribution line is known (for example, refer patent document 1). This ground short-circuit instrument includes a wire connecting portion made up of a first type and a second type having a wire receiving portion having a semicircular cross section, and has a needle electrode in the wire receiving portion. Then, at the clamping position where the first type and the second type are coupled, the tip of the needle electrode reaches the core portion of the distribution line and is electrically connected.

  On the other hand, there is known a connection clamp device that eliminates the need for stripping the insulation coating of the distribution line when attaching the bypass cable to the distribution line (see, for example, Patent Document 2). In this connection clamp device, a movable contact base equipped with a contact blade that penetrates the insulation coating of the distribution line is arranged below the clamp body, and a contact blade is provided on the upper part of the clamp body so as to face the contact blade. The electric wire holding part is arranged.
