Abstract
The utility model discloses a kind of combined type carbon brush, described combined type carbon brush comprises: left brush body, the upper right of this left brush body is provided with the step extending to the right, and the right flank of this left brush body is provided with the dovetail boss that is vertical, simultaneously, this step is provided with vertical through hole, and this step upper end is connected with left wire; Right brush body, the upper surface of this right brush body withstands on the downside of this step, and the dovetail groove that the left surface of this right brush body is provided with and this dovetail boss matches, and meanwhile, is connected with right wire on the upper surface of this right brush body, and this right wire is upward through this through hole; And this left wire and this right wire upper end are all connected on a bus, the upper end of this bus is connected with copper brace.The utility model has the advantages that: working stability, globality is better.
Description
Technical field
The present invention relates to motor accessory technical field, especially relate to a kind of combined type carbon brush.
Background technology
Carbon brush is the indispensable accessory of conventional motors, higher as the frequency of its replacing of running stores.At present, most carbon brush are unitary structure, thereby work is stable not.Put into mode even if having is close together 2 carbon brush monomers to use to make it have comparatively stable operating state, also because the two is in conjunction with defective tightness poor effect.
Summary of the invention
The object of this invention is to provide a kind of combined type carbon brush, it has working stability, and preferably feature of globality.
The technical solution adopted in the present invention is: combined type carbon brush, and described combined type carbon brush comprises:
Left brush body, the upper right of this left brush body is provided with to the right the step extending, and the right flank of this left brush body is provided with the dovetail boss that is vertical, and meanwhile, this step is provided with vertical through hole, and this step upper end is connected with left wire;
Right brush body, the upper surface of this right brush body withstands on the downside of this step, and the dovetail groove that the left surface of this right brush body is provided with and this dovetail boss matches, and meanwhile, is connected with right wire on the upper surface of this right brush body, and this right wire is upward through this through hole; And
This left wire and this right wire upper end are all connected on a bus, and the upper end of this bus is connected with copper brace.
The advantage that the present invention has is: working stability, globality is better.Combined type carbon brush of the present invention adopts the carbon brush of 2 monomers to combine, thereby work is comparatively stable.Meanwhile, between the carbon brush of two monomers, not only top, by the stopping of step, makes right brush body hold out against the step of left brush body, and dovetail structure links together the two closely, thereby globality is better.And left wire forms after " Y " type is connected and puts and be connected to brace with right wire, thereby has further improved the stability of this combined type carbon brush work.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks cutaway view;
Fig. 2 is that A-A of Fig. 1 is to view.
In figure: 10, left brush body, 11, step, 111, through hole, 12, dovetail boss, 13, left wire; 20, right brush body, 21, dovetail groove, 22, right wire; 30, bus; 40, brace.
Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: combined type carbon brush, comprises the left brush body 10 and the right brush body 20 that are arranged side by side.Concretely, the upper right of this left brush body 10 is provided with the step 11 extending to the right, and this step 11 is provided with vertical through hole 111, and these step 11 upper ends are connected with left wire 13.Meanwhile, the right flank of this left brush body 10 is provided with the dovetail boss 12 that is vertical.The upper surface 21 of this right brush body 20 withstands on the downside of this step 11.Meanwhile, the dovetail groove 21 that the left surface of this right brush body 20 is provided with and this dovetail boss 12 matches., after being buckled well with this dovetail boss 12, this dovetail groove 21 promotes from bottom to up this right brush body 20, until the upper surface of this right brush body 20 holds out against on the downside of this step 11.And, on the upper surface of this right brush body 20, being connected with right wire 22, this right wire 22 is upward through this through hole 111.And this left wire 13 and these right wire 22 upper ends are all connected on a bus 30, the upper end of this bus 30 is connected with copper brace 40., this left wire 13 and this right wire 22 are not all connected directly to this brace 40.Like this, by the combination of two carbon brush connecting as one, make this combined type carbon brush work comparatively stable, and left wire 13 and right wire 22 that " Y " type connects further improve the stability of this combined type carbon brush work.
Conventionally, this left brush body 10 and right brush body 20 all adopt the preparation of electrographite material with carbon element.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
