Description
Technical field
The utility model relates to a kind of break that is used on the motor, relates in particular to a kind of electromagnetism power-off brake.
Background technique
Electromagnetism power-off brake of the prior art is a kind of very common break; Generally comprise break body and a rectifier that is used with the break body, its break body has a magnetic shell, and the outside of magnetic shell is the urceolus cylindraceous of end sealing; Having inside of urceolus by the outward extending stationary magazine creel of the closed end of urceolus; Have coil between the periphery wall of stationary magazine creel and the inner circle wall of urceolus, coil is set on the stationary magazine creel, and the coil is here formed around upper conductor by a coil rack; Its coil rack is cylindric and is located on the stationary magazine creel through its inner hole sleeve; The two ends, the outside of coil rack have the retaining edge of turning up, and the part that coil is between the two retaining edges is the coiling part of coil, and its lead just is on this part.Magnetic shell is provided with the magnetic lid, and the magnetic lid is assembled together through screw and magnetic shell, and the opening end of urceolus is sealed up, and makes coil be in fully in the structure of a sealing.Because the break body needs between that rectifier is set when being used with motor, therefore, two the end of a thread of coil are by on two pins stretching and be connected rectifier in the magnetic shell, and two other pin of rectifier is used for linking to each other with motor.Like this, the rectifier and the break body that are used with the break body structurally are two independently parts, are connected through lead between the two, and integrated degree is not high.
Summary of the invention
The purpose of the utility model is to provide a kind of electromagnetism power-off brake; To solve in the existing technology outside and the break body that rectifier because of the electromagnetism power-off brake is in the break body is two independently parts, and the not high problem of integrated degree of the electromagnetism power-off brake that causes.
For realizing above-mentioned purpose; The utility model adopts following technological scheme: a kind of electromagnetism power-off brake comprises magnetic shell and rectifier, the magnetic shell interior loop; Two the end of a thread of coil are electrically connected with two pins of rectifier respectively; Two other pin of said rectifier is used for linking to each other with motor, and described rectifier is arranged in the said magnetic shell, the separated heat-insulating structure that is provided with between said rectifier and the coil.
Described rectifier is sticked at the coiling position of said coil; Said heat-insulating structure is an organic silicon insulation paper; Said rectifier is sticked at the coiling position of coil through organic silicon insulation paper, and said organic silicon insulation paper is sticked on coil, and said rectifier is sticked on organic silicon insulation paper.
The arranged outside of described coil has high temperature resistant enamelled coating.
Described rectifier is a diode rectifier.
Be powered with the cable that stretches out magnetic shell on two pins that rectifier is used for linking to each other with motor.
The rectifier of the electromagnetism power-off brake of the utility model is arranged in the magnetic shell, and whole electromagnetism power-off brake is structurally as a whole, and integrated degree is high; And rectifier is in the magnetic shell; Not fragile, in addition, the separated heat-insulating structure of having established between rectifier and coil; Be used to intercept the heat that coil produces, guaranteed the operating temperature of rectifier.
