Description
Technical field
The utility model relates to electric motors, and in particular to a kind of back cover of motor.
Background technique
It is a kind of rotating electric machine that direct current energy can be converted into mechanical energy that dc motor, which is commonly called as motor, is widely used
Every field in life.Motor mainly has magnetic pole, base, brush, commutator and rotor to constitute, and brush is fixed on base
After cover, brush and commutator cooperate so that motor can realize rotation at work.Important composition one of of the brush as motor,
Its structure it is reasonable whether, quality height have a significant impact to the service life of motor.Existing brush is when fixed with rear cover
Only it is embedded into rear cover by the interference fit of itself, will appear loose phenomenon in use for some time, leads to opening for motor
It moves unstable.
Summary of the invention
That the technical problem to be solved by the utility model is to provide a kind of structures is simple, brush can be reliably fixed on after
The back cover of motor covered.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of back cover of motor, including brush and
The rear cover of motor base, one end of the brush are fixedly installed brush head, and the other end of the brush has been wholely set end
Son, center symmetric setting has 2 brushes in the rear cover, and the side of the brush other end is integrally fixedly installed fixation
One end of block, the fixed block and the terminal is integrally fixed, and the fixed block is mutually fixed with rear cover, the terminal
It for stepped ramp type, is covered after described and is symmetrically arranged with the perforative jack with mounting terminal, the jack is on the outside of rear cover
Partial width be greater than front side part.
Preferably, the rear cover is circle, is fixedly installed 2 brushes in the rear cover, and 2 brushes are about rear
The center of circle of lid is centrosymmetric.
Preferably, it is provided in the middle part of the fixed block for the mounting hole by rivet, the rear cover is provided with
The fixation hole matched with mounting hole, the fixed block cover after being fixedly mounted on by rivet.
Preferably, lateral sides separate before the boss of terminal, and the inner wall of the rear side of the separate section and jack of boss offsets.
Preferably, the brush head of the brush is electrographite carbon brush.
Preferably, the brush, fixed block, terminal are vertically arranged two-by-two.
Compared with prior art, this practical advantage is terminal setting stepped and the front end of step is utilized icking tool
Separated to two sides, at the same after cover the corresponding step-like jack of setting so that terminal offsets with jack.Secondly the side of brush
It is fixedly installed fixed block, fixed block mutually fixes the stability for further strengthening brush by rivet with rear cover.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing motor electrical brush and rear cover；
Fig. 2 is the schematic diagram of the section structure of the terminal of the utility model；
Fig. 3 is the bottom view of the rear cover of the utility model.
Fig. 4 be Fig. 3 along the sectional view of A-A；
Fig. 5 is the side schematic view of the brush of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in the picture, a kind of back cover of motor, the rear cover 1 including brush 2 and motor base, the rear cover 1 are circle,
2 brushes 2 are fixedly installed in the rear cover 1, and 2 brushes 2 are centrosymmetric about the center of circle of rear cover 1.
One end of the brush 2 is fixedly installed brush head 3, and the brush head 3 of the brush 2 is electrographite carbon brush.Institute
The other end for the brush 2 stated has been wholely set terminal 4, and center symmetric setting has 2 brushes 2, the electricity in the rear cover 1
The side for brushing 2 other ends is integrally fixedly installed fixed block 5, and one end of the fixed block 5 and the terminal 4 is integrally solid
Fixed, the fixed block 5 is fixed with 1 phase of rear cover, and the terminal 4 is stepped ramp type, is symmetrically arranged with and is run through on the rear cover 1
The jack 6 with mounting terminal, partial width of the jack 6 on the outside of rear cover be greater than front side part；The electricity
Brush 2, fixed block 5, terminal 4 are vertically arranged two-by-two.
The middle part of the fixed block 5 is provided with for by the mounting hole 7 of rivet 10, the rear cover 1 be provided with
The fixation hole 8 that mounting hole matches, the fixed block 5 are fixedly mounted on rear cover 1 by rivet 10.
Lateral sides separate before the boss 9 of terminal 4, and the separate section of boss 9 and the inner wall of the rear side of jack 6 offset；In
In assembling process, the boss 9 of 4 front end of terminal is first mounted in jack 6, then passes through terminal push type broach 11 from the other side to jack 6
Boss 9 in upper is separated, and makes the main part partially away from terminal 4 of boss 9, to make itself and step-like jack 6
It offsets, terminal 4 is reinforced.
Above embodiments are merely to illustrate the technical solution of the utility model, rather than limit it；And according to aforementioned implementation
The utility model is described in detail in example.Although being made that the single technical staff of detailed description still can be to this technology side
Case is modified or is replaced on an equal basis；The modification or same replacement that technical staff makes in the case where not paying creative make great efforts still exist
In the protection scope of the utility model.
