Abstract

The utility model discloses a circuit board dustproof construction of motor, lid and circuit board behind the motor, the circuit board is fixed and is covered behind the motor, and the outer tip of lid is equipped with the mounting hole of indentation behind the motor, and the circuit board is fixed in the mounting hole, and the surface is less than behind the motor lid surface, and in the mounting hole was gone into in the indentation installation, and clamped the shield on the circuit board, covered and put on the circuit board. The utility model discloses both can easy to assemble, can need not to dismantle lid behind the motor again when maintaining the circuit board.

Description

Circuit board dustproof construction of motor
Technical Field
The utility model relates to a circuit board dustproof construction of motor belongs to the motor spare part field.
Background
The existing servo motors are all provided with circuit boards, and the circuit boards are usually installed in the rear covers of the motors. When the motor is installed, the circuit board is installed firstly, then the motor rear cover is installed, and the rear cover covers the circuit board to play a role in protection. When the circuit board is maintained, the rear cover of the motor needs to be detached firstly and then maintained. Thus, the installation and the maintenance are inconvenient.
Disclosure of Invention
An object of the utility model is to provide a circuit board dustproof construction that both can easy to assemble, can need not to dismantle the lid again when maintaining the circuit board behind the motor.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a circuit board dustproof construction of motor, covers behind motor and circuit board including, the circuit board is fixed and is covered behind the motor, and the outer tip of lid is equipped with the mounting hole of indentation behind the motor, and the circuit board is fixed in the mounting hole, and the surface is less than behind the motor lid surface, and in the mounting hole was gone into in the indentation installation, and clamped the shield on the circuit board, covered and put on the circuit board.
Preferably, three fixing holes are uniformly distributed on the periphery of the circuit board and fixedly connected with the rear cover of the motor through corresponding screws. The notch of mounting hole is radial groove, facilitates the use screw to install, improves the installation effectiveness.
Preferably, the peripheral edge department of circuit board is equipped with the three draw-in groove of equipartition, and the bottom of shield has three card posts that clamp with the draw-in groove. The dustproof cover is convenient to install, and after the dustproof cover is covered, an installation gap of the electronic element can be provided between the dustproof cover and the circuit board.
Preferably, after the dustproof cover is clamped and covered, the surface of the dustproof cover is flush with the end face of the motor rear cover. The surface is smooth.
Preferably, after the dustproof cover is clamped and covered, the peripheral edge of the dustproof cover abuts against the inner wall of the mounting hole. The dustproof effect is improved.
After the structure of the oil adding device is adopted, the utility model discloses fix the circuit board in the mounting hole, and the surface is less than behind the motor lid surface, in the mounting hole was gone into in the indentation installation, and clamped the shield on the circuit board, the lid was put on the circuit board. The structure that the retracted structure covers the dustproof cover again can improve the dustproof effect and protect the circuit board from being lost by external force; and when maintaining the circuit board, need not to dismantle the motor back cover, only need unpack the shield can.
Drawings
FIG. 1 is a perspective view showing an opened state of the dust cap according to the present invention;
FIG. 2 is a bottom view of the dust cover;
fig. 3 is a top view of fig. 2.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.
The first embodiment is as follows: referring to fig. 1-3, a circuit board dustproof structure of a motor comprises a motor rear cover 1 and a circuit board 2, wherein the outer end portion of the motor rear cover 1 is provided with a retractable mounting hole 3, three fixing holes 5 are uniformly distributed on the periphery of the circuit board 2, the fixing holes 5 are uniformly distributed round holes arranged along the outer edge of the circuit board 2, and the fixing holes 5 are fixedly connected with a step surface protruding from the inner wall of the mounting hole 3 of the motor rear cover 1 through corresponding screws 6. After the circuit board 2 is installed, the surface is lower than the surface of the motor rear cover 1, and after the circuit board is retracted, the circuit board is installed in the installation hole 3, so that the protection grade is improved.
Referring to fig. 2 and 3, three clamping grooves 7 are uniformly distributed at the peripheral edge of the circuit board 2, and three clamping posts 8 clamped with the clamping grooves 7 are arranged at the bottom of the dustproof cover 4. The card post 8 of shield 4 corresponds draw-in groove 7 and clamps, and shield 4 clamps the lid and closes the back, and the surface flushes with the terminal surface of lid 1 behind the motor, and the periphery border offsets with mounting hole 3 inner wall. The flatness of the end part of the motor is ensured, and the dustproof effect is also improved.
The utility model discloses during the installation, can install lid 1 behind the motor on motor body earlier, then install circuit board 2, clamp shield 4 after the installation is accomplished again. When the circuit board 2 is maintained, only the dust cover 4 needs to be disassembled, and the motor rear cover 1 does not need to be disassembled. The installation and maintenance are both convenient.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
