The insulating puncture wire clamp mainly comprises an insulating shell, a puncture blade, a sealing gasket, a high-strength bolt, a torque nut and a cable terminal cap sleeve, when a cable needs to be branched or connected, a cable branch wire terminal is inserted into the waterproof terminal cap sleeve, after the branch position of a main wire is determined, the torque nut on the wire clamp is screwed by a socket wrench, the puncture blade can puncture a cable insulating layer and is in contact with a conductor, the sealing gasket annularly presses the periphery of the punctured position of the cable, when the torque reaches a set value, a nut torque mechanism falls off, and the main wire and the branch wire are connected.
At present, the working of plastics and the rubber piece of puncture fastener on the market, though can play certain insulating effect, in actual production, installation and use, the quality and the installation technique of ordinary working of plastics and rubber piece hardly reach the insulating nature of expectation, and current puncture fastener still has the defect that the structure is complicated, the performance is unreliable, the installation is not convenient.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance, connect reliable, install convenient puncture fastener.
In order to achieve the purpose, the utility model discloses a puncture wire clamp, including base, upper cover, puncture blade, bolt, torque nut, base, upper cover and be provided with the storage tank that is used for placing the puncture blade respectively, the one end of puncture blade alternate in the storage tank, and one of puncture blade serves and is provided with the spacing portion of arc arch, the spacing portion block of arc arch in the storage tank, and constitute the puncture blade respectively with the spacing cooperation of base, upper cover, the other end of puncture blade on be provided with a plurality of puncture teeth of extension in the wire-pressing groove of base, upper cover respectively, and be provided with the silicone grease on each puncture tooth, the bolt pass base, upper cover in proper order and screw torque nut.
The beneficial effect of above-mentioned structure is: the base and the upper cover of the puncture wire clamp are both made of aluminum alloy materials, the puncture wire clamp is light in specific gravity and energy-saving, the manufacturing process adopts die-casting or casting molding, the product is small in deformation and high in precision, the puncture wire clamp is tightly matched with a puncture blade, the puncture force is transmitted uniformly, the electrical conductivity is good, the upper cover and the base cannot age, and stable electrical performance and weather resistance are guaranteed. And the puncture blade is assembled with the base and the upper cover in a limiting matching mode, so that the puncture blade can be effectively prevented from being reversely mounted, the puncture teeth are provided with silicone grease, and the silicone grease is extruded to automatically fill gaps of an insulating layer of the cable, so that the penetrated insulating layer is still in a sealed and insulated state, and the service life of the cable is ensured. Therefore, the puncture wire clamp has the advantages of simple structure, stable performance, reliable connection and convenient installation.
In particular, the plurality of piercing teeth are arranged at intervals, and the tangent of the tip of each piercing tooth is arc-shaped. Design into circular-arc with the prong tangent line of puncture tooth, the puncture tooth can more laminate the external diameter of cable, guarantees that every puncture tooth can both contact the conductor in the cable, is favorable to improving the puncture effect of this puncture fastener.
Particularly, the upper cover is provided with a through hole with a sector-shaped cross section, and the bolt is inserted in the through hole and forms free matching of the upper cover and the bolt. The upper cover adopts the fan-shaped through hole, and when the installation, the bolt freely swings in the through hole to this puncture fastener can adapt to the installation of different external diameter cables, and application scope is wider.
Particularly, the bolt is a square head bolt, a limiting groove is formed in the base corresponding to the head of the bolt, the head of the bolt is clamped in the limiting groove, and the base is in limiting fit with the bolt.
