Description

Carbon brush holder with insertion film trap structure

Technical field

The utility model relates to a kind of motor component, espespecially a kind of carbon brush holder with insertion film trap structure.

Background technology

Carbon brush holder is the important parts of motor, and effect is by spring pressure to be added on the carbon brush holder that contacts with commutator or collector ring surface sliding, makes its conduction current stably between fixed body and rotary body.

At present, referring to Fig. 1, Fig. 2, casing end face 110 peripheries of its support body 1 of existing carbon brush holder are generally around continuous support body outer wall 11 is arranged, thereby so that when the welding of the wire that carries out the parts such as electric capacity 4 and piezo-resistance 3 and inserted sheet 2 very limited of operating space, so the welding of wire and inserted sheet 2 can only be adopted the less demanding soldering in operating space is carried out, but soldering need to expend more tin material, and cost is higher and affect outer aesthetic.

Simultaneously; see also Fig. 2; Fig. 3; the position that the support body 1 of existing carbon brush holder is installed at corresponding protector 5 forms a protector mounting groove 15; and only offer two protector pin through holes 151 in the position of protector mounting groove 15 bottoms correspondence protector 5 pins; when protector 5 is installed from the casing end face 110 protector mounting groove 15 of packing into; protector 5 pins penetrate protector pin through hole 151; then carbon brush holder must be turn to gear box face 120; proceed again the weld job of protector 5 pins and other elements; so whenever at installation protector 5 time, all must increase the together operation of upset, increase the complexity of installing.

In addition, see also Fig. 3, the inserted slot 12 of existing carbon brush holder is the straight groove structure that cooperates with inserted sheet 2; Therefore the mould drawn needle must be grown and be thin, thereby so that drawn needle snaps when the processing straight trough easily, die life is low.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of carbon brush holder with insertion film trap structure is provided, and realized the not carbon brush holder of frangibility of a kind of mould drawn needle, have the saving raw material, reduce cost, environmental protection, the characteristics that installation procedure is succinct, the matching die life-span is long.

The technical scheme that realizes above-mentioned purpose is:

A kind of carbon brush holder with insertion film trap structure of the present utility model comprises the support body that is formed with two inserted slots, and described inserted slot inwall forms a plurality of axial strip depressions.

The utility model makes it have following beneficial effect owing to adopted above technical scheme:

The inserted slot inwall forms a plurality of axial strip depressions, thereby so that the both sides of the drawn needle of processing inserted slot can increase the ribs corresponding with the strip recessed position in the matching die of carbon brush holder, thereby reach the effect of strengthening drawn needle rigidity, prevent that drawn needle from adding losing of man-hour, prolonged the life-span of mould.

Embodiment

The utility model is described in further detail below in conjunction with specific embodiment.

See also Fig. 4, Fig. 5; a kind of carbon brush holder with insertion film trap structure of the present utility model; comprise that the support body 1, two that is formed with two inserted slots 12 and a protector mounting groove 15 plugs the inserted sheet 2, that is fixed in the inserted slot 12 and is fixed in the protector 5 in the protector mounting groove 15 and electric capacity 4 and the piezo-resistance 3 that is fixed in the casing end face 110 of support body 1; the support body outer wall 11 of casing end face 110 peripheries forms an opening 111 in corresponding two inserted sheets 2 positions; two inserted sheets, 2 afterbodys form respectively a groove 21, and the wire clamp of electric capacity 4 and piezo-resistance 3 is welded in the groove 21.

See also Fig. 4, Fig. 6, protector mounting groove 15 is the groove that cooperates with protector 5, and support body 1 forms butting section 13 in the outside of protector mounting groove 15 casing end faces 110 sides.

See also Fig. 5, butting section 13 comprise two be parallel to casing end face 110 and be positioned at support body outer wall 11 casing end faces 110 side ends two against sheet 131; Be fixed in respectively the outside of protector mounting groove 15 casing end faces 110 sides by a locating part 132 that is vertically installed in protector mounting groove 15 both sides against sheet 131.

See also Fig. 7, inserted slot 12 inwalls form a plurality of axial strip depressions 121.

The opening 111 that corresponding two inserted sheets 2 positions form has formed the operating space when the welding of the wire that carries out the parts such as electric capacity 4 and piezo-resistance 3 and inserted sheet 2, cooperate the groove 21 at inserted sheet 2 tops to realize that the folder weldering that the operating space is had 2 of necessarily required wire and inserted sheets replaces soldering, save the consumption of tin material, reduced production cost and outer aesthetic.And protector mounting groove 15 is groove; the butting section 13 that cooperates support body 1 to form; realized that protector 5 can directly pack into from gear box face 120; so that the installation of protector 5 and be weldingly fixed on the same face and carry out; saved conventional turn-over operation necessary during from casing end face 110 installation protector 5; so that the installation of carbon brush holder is more convenient, improved the formation efficiency of carbon brush holder.Inserted slot 12 inwalls form a plurality of axial strip depressions 121, thereby so that the both sides of drawn needle of processing inserted slot 12 can increase and strip ribs corresponding to 121 positions that cave in the matching die of carbon brush holder, thereby reach the effect of strengthening drawn needle rigidity, prevent that drawn needle from adding losing of man-hour, prolonged the life-span of mould.

Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not consist of restriction of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.

Claims (1)

1. the carbon brush holder with insertion film trap structure comprises the support body that is formed with two inserted slots, it is characterized in that, described inserted slot inwall forms a plurality of axial strip depressions.
