Problems solved by technology
[0003] The current guide plate installation structure adopted by the DC motor is as follows: figure 1 As shown, buckles or slots are provided on the insulating fixing plate 1, and the conduction plate 2 is loaded into the buckling of the insulating fixing plate by forcible pressing. This structure has the advantages of simple design and low manufacturing cost, but there are Several shortcomings: 1. It is difficult to install and there is a risk of falling off
During assembly, it is necessary to apply a large external force to turn the conductive plate into the buckle of the insulating fixing plate. There is a problem that the pressing is too laborious and causes operator fatigue, and the buckle of the insulating fixing plate is damaged to some extent when it is forcibly pressed in. Phenomenon, resulting in the hidden danger of the conductive plate falling off after being pressed in; 2. The axial direction of the conductive plate lacks a limit
There is no axial limit, which may cause the assembled guide plate to shift and affect normal work

The invention discloses an installation structure of a breakover plate of a direct current motor. The installation structure comprises an insulation fixing support and the breakover plate and is characterized in that at least a pair of buckles or clamping grooves is arranged on the insulation fixing support, the buckles or the clamping grooves correspond to each other, protruding sides are arranged on two sides of the breakover plate, and the protruding sides of the breakover plate are embedded in the buckles or the clamping grooves of the insulation fixing support to enable the breakover plate to be installed on the insulation fixing support. The installation structure has the advantages that the breakover plate is axially and slidingly installed on the insulation fixing support, and the buckles are matched with the protruding sides to achieve location of the breakover plate. The installation structure solves the problem that assembly in a traditional installation mode of the breakover plate wastes labor, the buckles of the insulation fixing support have certain damage, and the assembled breakover plate shifting is easy to shift and drop. The installation structure is characterized by being simple in structure, easy and convenient to assemble and good in reliable in fixation after assembly, and bringing convenience to mass production.
Description
technical field [0001] The invention relates to a motor conduction plate installation structure, in particular to a direct current motor conduction plate installation structure applied to a three-phase brushless direct current motor. Background technique [0002] In order to solve the problem of electric corrosion of DC motor bearings, people have invented a three-phase brushless DC motor with an anti-electric corrosion structure. This motor is formed by connecting the first side end cover and the second side end cover of the motor through a conductive plate. The equipotential body reduces the voltage difference between the stator and the shaft, so that the pressure difference between the inner and outer rings of the bearing is effectively reduced, so that the oil mold of the bearing will not be broken down, so that the electric corrosion of the bearing can be prevented and the service life of the motor can be prolonged. [0003] The current guide plate installation structu...
