Abstract
The invention discloses an insulator set clamp and support clamps of the insulator set clamp. The sheath wall of a supporting part of each support clamp jacks outwards a pushing part through a wheel poking part and then pushes a contact piece through the corresponding pushing part outwards, and finally the support clamps are assembled in a tubular busbar through the contact pieces in a tensioned mode. In the using process, when a fixing part is inserted to the front of a tube opening of the tubular busbar, the inner ends of the pushing parts are located in sediment grooves in the wheel poking parts, the contact pieces on the supporting parts are not jacked by the pushing parts and naturally contract, and accordingly the support clamps can be conveniently and wholly inserted into the tube opening of the tubular busbar; after the support clamps are wholly inserted into the tube opening of the tubular busbar, the wheel poking parts are then rotated or pulled, the inner ends of the pushing parts are moved to the peripheral faces from the sediment grooves of the wheel poking parts, the peripheral faces of the wheel poking parts jack the contact pieces outwards through the pushing parts, and the support clamps are assembled in the tubular busbar in the tensioned mode. The insulator set clamp has the advantages that assembling is convenient, the structure is simple, and small space is occupied.
