Abstract
A novel brush bracket for an auto electric fuel pump mainly solves the problem that the assembly elements of a conventional brush bracket are cumbersome, and have low qualification rate and high cost, and is characterized in that a carbon brush mounting base (2) is arranged on a brush bracket main body (1), the carbon brush mounting base (2) and the brush bracket main body (1) adopt an integrated structure, element mounting bases are positioned on the brush bracket main body (1) on the same side as the carbon brush mounting base (2). The novel brush bracket for the auto electric fuel pump adopts the design that the carbon brush fixing seat and the brush bracket main body are integrated, and the elements are arranged on one side, so that the assembly is easy, and two oil-proof and heat-proof fluoroplastic sheaths are not needed. The novel brush bracket for the auto electric fuel pump has the characteristics of easiness in assembly, high qualification rate and low cost.
Description
Technical field
The utility model relates to the parts on a kind of motorcar electric fuel pump, is specifically related to the novel brush holder of a kind of motorcar electric fuel pump.
Background technology
Brush holder is the critical piece in the motorcar electric fuel pump, mainly plays a supportive role, and elements such as carbon brush holder, carbon brush, solenoid, electric capacity are installed on the brush holder main body.There is following defective in existing brush holder: 1, the installation site of each element is that the two sides arranges that the carbon brush holder adopts separate piece made of copper, and assembling element is loaded down with trivial details, is not easy to assembling, and qualification rate is low, and efficiency of assembling is low; 2, assemble each element after, need the two sides that the oil-resisting and heat-resisting sheath is installed, and adopt carbon brush holder made of copper, cost height.
Summary of the invention
Existing brush holder assembling element is loaded down with trivial details in order to overcome, qualification rate low and the high deficiency of cost, the utility model provides a kind of motorcar electric fuel pump novel brush holder, the novel brush holder of this motorcar electric fuel pump adopts carbon brush holder and the main body integrated design of brush holder, each element pedion is arranged, not only be easy to assembling, and replaced two oil-resisting and heat-resisting fluorine with the coil injection cap and moulded the pyrocondensation sheath, have be easy to assemble, qualification rate height and the low characteristics of cost.
The technical solution of the utility model is: the novel brush holder of this motorcar electric fuel pump comprises brush holder main body and element mount pad, the brush holder main body is provided with the carbon brush mount pad, described carbon brush mount pad and brush holder main body are structure as a whole, and the position of element mount pad all is arranged on the brush holder main body with carbon brush mount pad homonymy.
The material of described brush holder main body is engineering plastics.
Described element mount pad comprises coil stationary hole, electric capacity installing hole, spring erection column, coil cap and spring limited post.
The beneficial effects of the utility model are: owing to take such scheme, when being installed, each element only need the one side operation to get final product, because carbon brush mount pad and brush holder main body are one, the positional precision of carbon brush mount pad guarantees during by injection moulding brush holder main body, cause site error when having avoided installation elements, guarantee the assembly precision of element, be easy to assembling, the qualification rate height.Because each element is positioned at the same side of brush holder main body, replace two oil-resisting and heat-resisting fluorine with the coil injection cap and moulded sheath, the carbon brush mount pad is identical with the material of brush holder main body, compare with background technology and to have saved two copper carbon brush mount pads and two oil-resisting and heat-resisting fluorine are moulded the pyrocondensation sheath, when having saved the assembler, reduced cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of coil installing hole 7 among Fig. 1.
1-brush holder main body among the figure, 2-carbon brush mount pad, 3-spring erection column, 4-electric capacity installing hole, 5-spring limited post, 6-coil cap, 7-coil installing hole.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, the novel brush holder of this motorcar electric fuel pump comprises brush holder main body 1 and element mount pad, brush holder main body 1 is provided with carbon brush mount pad 2, described carbon brush mount pad 2 is structure as a whole with brush holder main body 1, and the position of element mount pad all is arranged on the brush holder main body 1 with carbon brush mount pad 2 homonymies.Carbon brush mount pad 2 and together injection mo(u)lding of brush holder main body 1, when being installed, each element only need the one side operation to get final product, because carbon brush mount pad 2 is an one with brush holder main body 1, the positional precision of carbon brush mount pad 2 guarantees during by injection moulding brush holder main body 1, cause site error when having avoided installation elements, guarantee the assembly precision of element, be easy to assembling, qualification rate height.Because each element is positioned at the same side of brush holder main body 1, compare with background technology and to have saved two copper carbon brush mount pads and two oil-resisting and heat-resisting fluorine are moulded pyrocondensation sheath (substituting with coil injection cap 6), carbon brush mount pad 2 is identical with the material of brush holder main body 1, has reduced cost.
By shown in Figure 1, the material of described brush holder main body 1 is engineering plastics.Carbon brush mount pad 2 is identical with the material of brush holder main body 1, adopts engineering plastics to substitute in the background technology independently copper carbon brush mount pad, and easy for installation, cost is low.
In conjunction with shown in Figure 2, described element mount pad comprises coil stationary hole 7, electric capacity installing hole 4, spring erection column 3 and two coil caps 6 by Fig. 1.Be used to install elements such as solenoid, electric capacity, carbon brush, spring.
Claims (3)
1. novel brush holder of motorcar electric fuel pump, comprise brush holder main body (1) and element mount pad, it is characterized in that: brush holder main body (1) is provided with carbon brush mount pad (2), described carbon brush mount pad (2) and brush holder main body (1) are structure as a whole, and the position of element mount pad all is arranged on the brush holder main body (1) with carbon brush mount pad (2) homonymy.
