Abstract
The utility model discloses a stay insulator, and the stay insulator comprises two metal pull rings and an insulator, wherein the two metal pull rings are respectively fixedly connected to the upper and lower end parts of the insulator; one end of each metal pull ring is provided with a pull ring, and the other end is provided with a hollow sleeve; screw threads are arranged on the inner wall of the sleeve; a stud is arranged in an inner chamber of the sleeve; hollow connecting columns are arranged at both upper and lower end parts of the insulator; screw threads matched with the stud are arranged on the inner walls of the connecting columns; and screw threads matched with the inner wall of the sleeve are arranged on the external surfaces of the connecting columns. By being connected with the insulator by the sleeve internally provided with the stud, the stay insulator disclosed by the utility model implements dual connection and greatly enhances the mechanical tensile strength thereof.
Description
Technical field
The utility model belongs to electrical equipment technical field, relates in particular to a kind of guy insulator.
Background technology
Guy insulator is the seal for cable pole bracing wire on power line, and its product quality is determined by two large factors: 1, have tensile strength preferably, namely must bear larger pulling force; 2, have good insulation property, in case leak-stopping electricity casualty accident occurs.After existing guy insulator is installed in the bracing wire of the large specification of using at present additional, frequent fracture phenomenon, the reason circular arc that to be steel strand wire bend in installing insulating place can not and the installation circular arc of existing guy insulator fit like a glove, in a single day bracing wire establishes, will produce stress concentration point at the two ends of circular arc, lifting surface area with great pulling force and performance acts on guy insulator, gives crowded year old insulator, thus the generation that causes the accident.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide that a kind of tension mechanical strength is large, the guy insulator of good insulation preformance.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of guy insulator comprises two metal draw rings and insulator, and two metal draw rings are fixedly connected on respectively on the both ends up and down of insulator; Described metal draw ring one end is provided with draw ring, the other end is provided with the sleeve pipe of hollow, the inwall of sleeve pipe is provided with screw thread, be provided with double-screw bolt in the inner chamber of sleeve pipe, the upper/lower terminal section of described insulator is provided with the joint pin of hollow, be provided with the screw thread suitable with telling double-screw bolt on the inwall of joint pin, be provided with the screw thread suitable with internal surface of sleeve pipe on the outer surface of joint pin.
Further, the draw ring of metal draw ring and sleeve pipe are one-body molded.
Further, insulator adopts ceramic material to make.
Owing to adopting technique scheme, the utlity model has following superiority:
The sleeve pipe that is provided with double-screw bolt in this guy insulator adopts is connected with insulator, realized dual connection, greatly strengthened the tension mechanical strength of this guy insulator, simultaneously, insulator adopts ceramic material, has good insulation property, and the utility model is simple in structure, reasonable in design, have great promotional value.
