Description
Technical Field
The invention relates to the field of motors, in particular to an electric brush structure.
Background
The direct current motor needs a commutator to change the current direction in real time during rotation, so that the electric brush is particularly important during rotation of the direct current motor, the direct current electric brush needs to be grounded during high current operation, and the installation position of the current electric brush box is unstable.
Disclosure of Invention
In order to solve the problems, the invention provides a direct current motor brush holder, which comprises the following specific technical scheme:
the utility model provides a direct current motor brush yoke, is equipped with the base, the base cavity sets up, is equipped with two wire holders on two lateral walls of base, be equipped with two wires on the wire holder, the below of wire holder is connecting portion, and connecting portion are connected with the brush box, be equipped with the wire box in the brush box, the wire box is connected with the wire, and the opposite side of wire box is equipped with three side riser, be equipped with hold-down spring between the two side riser, hold-down spring's one end sets up between the two side riser, hold-down spring's the other end sets up between the rotatory piece, the rotatory piece sets up between the two side riser, and the cylindric lock wears to locate two side riser and the other end of hold-down spring with the hold-down spring coupling together, the second cylindric lock wears to locate two side riser and rotatory piece and hold-down spring to be in the same place, the tip of rotatory piece still is equipped with two return hooks.
The loop-shaped hook is provided with two inclined planes, one inclined plane is close to the brush box, and the other inclined plane is close to the motor.
The invention has the advantages that: the loop-shaped hook is contacted with the brush box for eliminating the phenomenon of large current,
so that the brush holder of the DC motor can run more smoothly.
