Description
Technical Field
The invention relates to a vibration-proof arc-shaped top armature structure for the field of motors.
Background
The brush of the motor is a conductive sliding contact body for transmitting energy or signals between a fixed part and a rotating part of a rotary machine such as a motor or a generator, and is also called a carbon brush. The top of the traditional electric brush is in an inclined plane state, so that the phenomenon of pressing or deflection can occur when the spring brush holder is pressed on the top of the electric brush, the situation of uneven pressing of the electric brush, poor contact of a clamping shell and the like can be caused, and the electric brush burst accident can occur under serious conditions. If the electric brush is in a problem in the direct current motor, spark is increased, and normal use of the motor is affected.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a vibration-proof arc-shaped top armature structure which can effectively prevent the phenomena of brush bias and uneven brush compression caused by the fact that a pressure spring is bent and falls off, and prevent the phenomena of shell clamping, bursting and the like.
The technical scheme for achieving the purpose is as follows: the vibration-proof arc-shaped top armature structure comprises an electric brush body connected with an electric brush joint and also comprises a vibration-proof connecting part arranged at the top of the electric brush body;
The vibration-proof connecting part comprises a rubber insulating pad and a U-shaped rubber pad, the rubber insulating pad is arranged at the top of the electric brush body, the U-shaped rubber pad is arranged on the rubber insulating pad, the cross section of the side surface of the U-shaped rubber pad is U-shaped, two connecting through holes are symmetrically formed in the rubber insulating pad and the U-shaped rubber pad, two insulating sleeves are inserted into the connecting through holes, and copper wire connectors are arranged in the two insulating sleeves and connected with the electric brush body;
The electric brush joint is provided with a pressure spring, the bottom of the electric brush joint is a protruding connecting part, and the electric brush joint is connected with the electric brush body through a copper wire.
Further, the brush joint is outwardly divided into two connecting wires, and each connecting wire is coated with an insulating layer.
Further, the thickness of the rubber insulating pad is 3-5cm.
According to the vibration-proof arc-shaped top armature structure, the rubber insulation pad and the U-shaped bakelite pad are additionally arranged at the top of the electric brush body, the connecting through holes are formed in the rubber insulation pad, the wires connected with the external insulation protection layer are connected with the electric brush connector, the U-shaped bakelite pad can furl the lead-out wire harness of the electric brush connector, so that the clamping position of the brush holding pressure spring of the electric brush connector is accurate, and the pressure spring is prevented from being bent and sliding; the rubber insulating pad can play a role in elastic vibration prevention, so that the running stability of the electric brush and the service life of the electric brush are improved, and the electric brush joint is prevented from being accidentally cheaper or disconnected due to overlarge vibration. The invention can effectively improve the running stability and efficiency of the motor.

The U-shaped rubber pad 22 is arranged on the rubber insulating pad 21 and is used for strengthening and fixing the butt joint part of the electric brush connector 3 and the electric brush body 1, the cross section of the side surface of the U-shaped rubber pad is U-shaped, and the outgoing line of the electric brush connector 3 can be bundled, so that the pressure spring of the electric brush connector 3 is accurate in clamping position, and the pressure spring is prevented from being pressed askew and sliding. Two connecting through holes are symmetrically formed on the rubber insulating pad 21 and the U-shaped rubber pad 22, two insulating sleeves 23 are inserted into the connecting through holes, and copper wire connectors connected with the electric brush body 1 are arranged in the connecting through holes.
Referring to fig. 3, the brush joint 3 is provided with a compression spring 31, the bottom of the brush joint 3 is a protruding connection part 33, and the brush joint 3 is connected with the copper wire joint at the top of the brush body 1 through a copper wire outgoing line 32. When the brush joint 3 is connected with the brush body 1, the pressure spring 31 is pressed down to enable the brush joint 3 to be close to the brush body 1, the brush joint 3 and the brush body are connected through the outgoing line and the joint, and the connecting portion 33 is clamped in the U-shaped groove and is not easy to fall off.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the invention, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the invention as long as they fall within the true spirit of the invention.
