Description
Technical Field
The utility model relates to an electric power fitting technical field, concretely relates to insulating puncture fastener.
Background
The puncture wire clamp has the characteristics of low cost, safety, reliability and maintenance-free property. The cable branch can be made without cutting off the main cable and stripping the insulating layer of the cable, the joint is completely insulated, live-line work can be performed, and the field branch can be made at any position of the cable. The insulating puncture clamp mainly comprises a base, an upper cover, a puncture blade, a sealing gasket, a high-strength bolt, a torque nut and a cable terminal cap sleeve, however, the structural design of the existing puncture clamp is unreasonable, so that the puncture clamp has the defects of incompact structure, inconvenient assembly, poor insulating property and unstable performance.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide an insulating puncture fastener that compact structure, installation are convenient, stable performance is reliable, insulating properties is good.
In order to achieve the purpose, the utility model discloses an insulating puncture fastener, including base, upper cover, rubber pad, moment bolt, the moment nut of setting in the base, the rubber pad on be provided with the insulating tube to stress moment bolt department, the upper end of this insulating tube is contradicted on the inner wall of upper cover, the moment bolt pass base, rubber pad, insulating tube, upper cover in proper order and screw strong moment nut, and be formed with two wire clamping cavities that are used for pressing from both sides tight cable between rubber pad and the upper cover, the rubber pad in be provided with the puncture blade, the both ends of puncture blade on correspond each wire clamping cavity punishment and do not be provided with the puncture tooth, the one end of rubber pad be provided with the sleeve pipe of interlude in one of them wire clamping cavity, be provided with the through-hole that can supply the cable to pass on the sleeve pipe.
The beneficial effect of above-mentioned structure is: be provided with the insulating tube on the rubber pad, the moment bolt alternates in the insulating tube, is favorable to improving the insulating properties of this puncture fastener, and is provided with the sleeve pipe that alternates in the wire clamping intracavity on the rubber pad, can avoid the rainwater to flow into the puncture department of cable along the cable, is favorable to improving the waterproof performance of this puncture fastener to this insulation puncture fastener has compact structure, the installation is convenient, the stable performance is reliable, insulating properties is good advantage.
Particularly, a clamping ring is arranged at one end of the rubber pad, a clamping plate is arranged on the base corresponding to the clamping ring, and the clamping plate is clamped in the clamping ring and forms clamping fit of the base and the rubber pad. The rubber pad and the base are assembled in a clamping fit mode, so that the base and the rubber pad are assembled conveniently, the assembly efficiency of the puncture wire clamp is improved, the rubber pad is not easy to fall off from the base, and the puncture wire clamp is convenient to install.
