Abstract
The utility model discloses a locomotive resistance cabinet side insulator. The ceramic comprises a ceramic body, a connecting hole and a groove, wherein an inner hole is formed in the middle of the ceramic body, the connecting hole is formed in two sides of the inner hole in the ceramic body, the connecting hole is a step hole and is symmetrically distributed on two sides of the inner hole, the groove is formed in the outer surface of the periphery of the ceramic body, and the cross section of the groove is rectangular or square. The utility model has the characteristics of compact structure, simple to operate, withstand voltage is high, change swiftly etc.
Description
Technical field
The utility model relates to a kind of electroceramics spare, and is especially relevant with the resistor box insulator.
Background technology
Existing locomotive resistor box side insulator does not have the structure that increases the product creepage distance because structure is single, and it is bigger to exist size, and institute takes up space big, shortcomings such as the product compressive resistance is low, in addition, because insulator does not have connecting hole, also exist fixing difficulty, connect inconvenience, change deficiencies such as trouble.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, and is easy for installation, the proof voltage height, changes locomotive resistor box side insulator efficiently.
For achieving the above object, the utility model is achieved through the following technical solutions.Locomotive resistor box side insulator comprises porcelain body and connecting hole, is provided with endoporus at the porcelain body middle part, and connecting hole is located at endoporus both sides on the porcelain body.
Described locomotive resistor box side insulator, its connecting hole is a stepped hole, and is symmetrically distributed in endoporus two limits.
Described locomotive resistor box side insulator also comprises groove, and groove is located at the outer surface around the porcelain body.
Described locomotive resistor box side insulator, its groove cross sectional shape is a rectangle or square.
The utility model compared with prior art has the following advantages: (one) is owing to endoporus both sides on porcelain body are provided with connecting hole, can inside square insulator and other holders be fastenedly connected by screw, thereby easy for installation, change quick; (2) be owing to groove is set around the porcelain body, thereby increased the creepage distance of product, improved compressive resistance, reduced product size.
