The hardware fitting comprises a combination sleeve, wherein the inside of the combination sleeve is provided with an upper step face and a lower step face, the outside of the upper portion of the combination sleeve is provided with an annular sealing groove, the upper portion of the combination sleeve is provided with a pressing cover in threaded connection with the combination sleeve in a screwed mode, the lower portion of the combination sleeve is provided with steel feet and a ball head, an expansion joint is reserved between the lower end face of the end of the pressing cover and the upper end face of the combination sleeve, the inside of the pressing cover is provided with a cone-shaped hole, the diameter of the upper portion of the cone-shaped hole is smaller than that of the lower portion of the cone-shaped hole, the upper step face of the inside of the combination sleeve is provided with a cone-shaped sleeve which is matched with the cone-shaped hole and is arranged on a mandrel in a sleeved mode, the side wall of the cone-shaped sleeve is provided with a vertical telescopic groove, and a cavity above the lower step face of the combination sleeve is a pressure buffering area. The hardware fitting eliminates the phenomenon that composite insulators are disconnected, and a power grid operates safely and reliably.
Description
Technical field
The present invention relates to electrical network with connecting gold utensil, be specially a kind of transmission line composite insulator end and connect gold utensil.
Background technology
Along with a large amount of uses of composite insulator in electrical network, the harm that single string composite insulator that end part of composite insulator gold utensil causes due to reasons such as crimp quality and brittle failures falls string happens occasionally, and brings potential safety hazard to the operation of electrical network.
Summary of the invention
The present invention, in order to solve existing compound inslation sub-connection gold utensil because unreasonable structure causes crimp quality poor and the problem that brittle failure phenomenon causes potential safety hazard easily occurs, provides a kind of transmission line composite insulator end to connect gold utensil.
The present invention adopts following technical scheme to realize: transmission line composite insulator end connects gold utensil, comprise that upper diameter is greater than the stepped combined sleeve of lower diameter, combined sleeve inside is provided with cascaded surface and downstairs face, combined sleeve upper outside has annular seal groove, combined sleeve top is screwed with the friction top being threaded with it, combined sleeve bottom is provided with steel pin and bulb, lower surface, friction top termination and combined sleeve upper surface are provided with expansion joint, friction top inside is provided with the tapered hole that upper diameter is less than lower diameter, on the upper cascaded surface of combined sleeve inside, be placed with and coordinate with tapered hole and be enclosed within the taper sleeve pipe on plug, taper sleeve pipe sidewall has vertical telescopic chute, the cavity of assembled casing downstairs face top is pressure buffer district.
During operation, by tightening friction top, taper sleeve pipe is tightened up along telescopic chute, thereby plug and taper sleeve pipe are fixed, extrusion stress when expansion joint is connected with combined sleeve for discharging friction top, flexible stress when pressure buffer district is used for discharging plug crimping, steel pin and bulb are for being connected with transmission pressure gold utensil, by cluster parachute silica gel sealing, come in seal groove locking, moistureproofly, overcome existing compound inslation sub-connection gold utensil because unreasonable structure causes crimp quality poor and the problem that brittle failure phenomenon causes potential safety hazard easily occurs.
Reasonable in design of the present invention is reliable, effectively guaranteed to meet the crimp quality that insulator end connects gold utensil, thoroughly stopped the generation of brittle failure phenomenon, and then stopped composite insulator and fallen to go here and there the generation of phenomenon, safe operation of electric network is reliable, has advantages of simple in structure, easy to process and cost is low.
