Abstract
A spacing-adjustable ground wire clamp relates to a ground wire clamp and is used to mainly solve the inconvenient ground connection problem of busbars of different thicknesses during power maintenance operation. The spacing-adjustable ground wire clamp comprises an upper wire-clamp contact, a movable contact, a lower wire-clamp contact and a ground wire crimping plate. The upper wire-clamp contact and the lower wire-clamp contact are arranged in parallel up and down and are fixed in a chute on the ground wire crimping plate through screws fixed on the side surfaces. In addition, the movable contact is arranged between the upper and lower wire-clamp contacts. A spring is arranged between the movable contact and the lower wire-clamp contact. The lower part of the ground wire crimping plate is provided with a bolt connected with a ground wire. Through a clamping space enclosed by the upper wire-clamp contact and the movable contact and by the compression effect of the spring, the inconvenient ground connection problem of busbars of different thicknesses during power maintenance operation is effectively solved.
