The utility model discloses the constitution includes: insulating housing (3), inside worn bolt (2) of insulating housing, bolt top be saw -shaped, the bolt pass through the sawtooth be connected with insulating moment nut (1), insulating housing middle part both sides the recess has, the recess in install the longitudinal symmetry respectively sealed cushion (4), sealed cushion internally mounted have puncture blade (5), recess left side install cable termination cap sleeve (7). The utility model is used for insulating piercing depth of power cable.
Description
Technical field:
This utility model relates to a kind of power cable insulation sting device.
Background technology:
Along with the development of society, the following power reguirements to building of high stratification development is more and more higher, the informationization of society, makes building that the dependence of power supply is also increasing, and power cable branch technique fast and convenient, reliable becomes a difficult problem for supply line's development.The branch technique of the power cable insulation sting device of this product has coordinated cable power supply mode dexterously, with its distinctive advantage, there is provided quick, easy for cable branch, connect reliably, the most rising supply line's branch technique can be become, the key technology of cable insulation sting device branch is puncture seal branched structure, adopt and add strong fiber plastics and specific alloy, improve the electrical contact performance of the mechanical strength of branch joint, waterproof anti-corrosion performance and branch.
Utility model content:
The purpose of this utility model is to provide a kind of power cable insulation sting device.
Above-mentioned purpose is realized by following technical scheme:
A kind of power cable insulation sting device, its composition includes: insulation shell, it is installed with bolt inside described insulation shell, it is zigzag fashion above described bolt, described bolt is connected with insulation torque nut by described sawtooth, and described both sides, insulation shell middle part have groove, are separately installed with laterally zygomorphic seal gasket in described groove, described seal gasket is internally installed piercing blade, is provided with cable termination cap sleeve on the left of described groove.
Described power cable insulation sting device, described insulation shell bottom surface is provided with spring washer, and on described insulation shell, Plane Installation has retaining spring washer, is installed with described bolt in described spring washer, described retaining spring washer.
Described power cable insulation sting device, described seal gasket is C font, and described insulation shell adopts closed structure, has waterproof silicone grease inside described insulation shell.
Beneficial effect:
1. this utility model is a kind of power cable insulation sting device, mainly solve this difficult problem of power cable branch technique fast and convenient, reliable, having coordinated cable power supply mode dexterously by the branch technique of power cable insulation sting device, this product can become the most rising supply line's branch technique.
The key technology of this utility model cable insulation sting device branch is puncture seal branched structure, adopt the insulation shell of interpolation strong fiber plastics and the piercing blade that specific alloy is silver-plated, it is possible to increase the electrical contact performance of the mechanical strength of branch joint, waterproof anti-corrosion performance and branch.
This utility model has simple installation, low cost, safe and reliable non-maintaining feature, it is not necessary to block leader cable, insulating barrier without peelling off cable can do cable branch, and joint is completely insulated, can livewire work, on-the-spot branch can be made in cable optional position, do not need to use termination rack, coupling box.
Bolt of the present utility model adopts high-strength bolt, warp resistance, adopts special retaining spring washer, spring washer simultaneously, can shockproof, waterproof, anticorrosion aging, using insulating puncturing device to do cable branch, comprehensive benefit is obvious, and cost performance is better than conventional conventional coupling arrangement.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the left view in accompanying drawing 1.
Accompanying drawing 3 is the connection figure of the insulation torque nut in accompanying drawing 1 and bolt.
Detailed description of the invention:
Embodiment 1:
A kind of power cable insulation sting device, its composition includes: insulation shell 3, bolt 2 it is installed with inside described insulation shell, it is zigzag fashion above described bolt, described bolt is connected with insulation torque nut 1 by described sawtooth, and described both sides, insulation shell middle part have groove, are separately installed with laterally zygomorphic seal gasket 4 in described groove, described seal gasket is internally installed piercing blade 5, is provided with cable termination cap sleeve 7 on the left of described groove.
Embodiment 2:
Power cable insulation sting device according to embodiment 1, described insulation shell bottom surface is provided with spring washer 8, and on described insulation shell, Plane Installation has retaining spring washer 6, is installed with described bolt in described spring washer, described retaining spring washer.
Embodiment 3:
Power cable insulation sting device according to embodiment 1, described seal gasket is C font, and described insulation shell adopts closed structure, has waterproof silicone grease inside described insulation shell.
Embodiment 4:
Power cable insulation sting device according to embodiment 1-3, described power cable insulation sting device is mainly by insulation shell, piercing blade, seal gasket, waterproof silicone grease, bolt, insulation torque nut and cable termination cap sleeve composition, when cable Xu Zuo branch or when continuing, cable branch line terminal is inserted waterproof terminal cap sleeve, after determining main line branch location, with the insulation torque nut on box spanner screw device, stab knife sector-meeting penetrating insulating layer of cable in process, with conductor contact, fluid sealant gasket ring voltage cable is punctured around position, in insulation shell, silicone grease overflows, when moment reaches setting value, the moment explosive separation of insulation torque nut, main line and branch line are switched on, and water resistance and electrical effects have reached the parameter of standard-required.
