Description
Technical field
This utility model relates to motor technology field, particularly relates to the binding post of a kind of threephase asynchronous.
Background technology
Make the threephase asynchronous machine of motor running.The rotating speed of three-phase asynchronous motor rotor is less than the rotating speed of rotating excitation field, and rotor windings produces electromotive force and electric current because there is relative motion between magnetic field, and produces electromagnetic torque with magnetic field interaction, it is achieved energy conversion.
Compared with monopole asynchronous motor, threephase asynchronous runnability is good, and can save various material.By the difference of rotor structure, threephase asynchronous can be divided into cage and Wound-rotor type two kinds.The Induction Motor Structure of cage rotor is simple, reliable, lightweight, low price, is widely used, and its major defect is speed governing difficulty.The rotor of wound three-phase asynchronous motor is the same with stator to be also provided with three-phase windings and is connected with outside rheostat by slip ring, brush.Standardsizing rheostat resistance can improve starting performance and the rotating speed of regulation motor of motor.
In prior art, the power line of threephase asynchronous is directly connected with internal electronic devices and components, after power line damages, need to take apart the shell of motor, then be replaced power line, bother very much, electronic devices and components for the personnel being ignorant of circuit engineering, it is easy to while taking motor apart, within damage, so that whole motor is scrapped, thus bring the biggest loss.
Summary of the invention
In view of this, it is necessary to a kind of binding post being easy to connect the threephase asynchronous of power line is provided.
nullThis utility model is realized in，A kind of binding post of threephase asynchronous，It is arranged on motor，Including cylindrical bump、Inserting terminal and power line，Described cylindrical bump is fixed on the outer wall of motor，The center of described cylindrical bump is provided with bullet groove，The bottom of described bullet groove is provided with electric shock shell fragment，Circuit within described electric shock shell fragment electrical connection electric motor，The port of described bullet groove is provided with a spacing rubber ring of circle，The internal diameter of described spacing rubber ring is less than the maximum gauge of described bullet groove，Described cylindrical bump is provided with circular depressed groove，Described circular depressed groove surrounds described bullet groove，Described inserting terminal includes cylindric block rubber、Plug connector and sealing ring，The shape of described plug connector is identical with described bullet groove，Plug connector is fixed on described cylindric block rubber，And connect described power line，Described plug connector is plugged in described bullet groove，The shape of described sealing ring is identical with the shape of described circular depressed groove，Described sealing ring is arranged on cylindric block rubber，And surround described plug connector，Described sealing ring is plugged in described circular depressed groove.
Further, described plug connector is provided with fluting, and described fluting is through the centrage of described plug connector, and described fluting extends to bottom from the middle part of plug connector.
The advantage of the binding post of a kind of threephase asynchronous that this utility model provides is: this utility model is rational in infrastructure simply, it is easy to be connected on motor power line by arranging cylindrical bump, inserting terminal and power line, and during the later stage uses, in the case of power line damages, have only to pull out inserting terminal, again one new inserting terminal of grafting and power line, convenient and swift, and need not take motor casing apart, being prevented effectively from the phenomenon generation damaging motor interior electronic devices and components, security performance is high.
