Embodiment

For being illustrated more clearly in the utility model, lift preferred embodiment now and cooperate diagram to specify as after.

Fig. 1 and shown in Figure 2 for the utility model provides the collector ring carbon brush holder 1 of a preferred embodiment, includes a connecting support 10, two conducting brackets 20 and two carbon brush 30.

This connecting support 10 is by the made conductor of conductive material; It has breach 14 and two faying faces 16 that an axis hole 12, is communicated with this axis hole; This axis hole 12 supplies a fixed axis (figure does not show) to wear; And respectively have one first screw 15 on the connecting support 10 corresponding to these breach 14 2 sides, supply a bolt 41 to penetrate, and this bolt 41 and two nuts 45 are locked on this connecting support 10; And dwindle the width of this breach 14 through this bolt 41 of screwing, so that the hole wall of this axis hole 12 is oppressed on this fixed axis (figure shows).This two faying face 16 is the expansion that stretches out of folder one predetermined angle each other downwards, and respectively has one second screw 17 on this two faying face 16.

This two conducting bracket 20 includes a shell fragment 22, two flaps 24 and two stiffening plates 26 respectively, wherein:

This shell fragment 22 has one first end 22a and one second end 22b; This first end 22a has a perforation 23, one bolts 42 and passes this perforation 23 and this second screw 17, this conducting bracket 20 is fixed on the faying face 16 of this connecting support 10; The second end 22b of this shell fragment 22 extends outside this connecting support 10; And form a folder between this 2 second end 22b and establish the space, again, this shell fragment 22 has the punching press of utilizing at the second end 22b place and cuts two clamps 27 that make; As shown in Figure 3, this two clamp 27 is and turns up and in being formed with a gap 28 to each other;

This two flap 24 is the mode of establishing be connected in this shell fragment 22 and be positioned on this first end 22a, to press from both sides between this two flap 24 and establish this connecting support 10, to use so that not these connecting support 10 swings relatively of this conducting bracket 20;

This two stiffening plate 26 also is the mode of establishing is connected with this shell fragment 22 and is positioned at this second end 22b; Specifically; This two stiffening plate 26 is good with corresponding position in the both sides in this gap 28, has the effect of strengthening this second end 22b intensity, to improve the non-deformability of this second end 22b.

Explanation is in addition, and each conducting bracket 20 does not exceed with above-mentioned with the fixed form that combines of each faying face 16, can also the spot welding mode for it.

This two carbon brush 30 respectively has the two corresponding grooves 32 that are provided with, and when this carbon brush 30 was arranged in the gap 28 of corresponding conducting bracket 20, groove 32 just was that clamp 27 embeds wherein (as shown in Figure 4), makes this carbon brush 30 firmly be incorporated on this conducting bracket 20.
