Description
Technical field
The present invention relates to motor accessory technical field, especially relate to a kind of carbon brush component.
Background technology
Carbon brush is as the main consumables of motor, thereby its lower end is arc surfaced all the time with the end of rotor contact, then very easily occurs the phenomenon of loose contact.
For this reason, the inventor has prepared a kind of carbon brush with good contact performance, and it has avoided the lower end of this brush body to form the situation of arc surfaced by brush body can be rotated in moving down, and has ensured that this brush body has good contact with rotor all the time.
But, to find in actual use, brush body wherein and the connection of wire are easy to occur the phenomenon of loose contact.
Summary of the invention
The object of this invention is to provide a kind of carbon brush component, it has and can be all the time keeps comparatively good contacting with rotor, and the also better feature of electrical connection of its brush body and wire.
The technical solution adopted in the present invention is: carbon brush component, and described carbon brush component comprises:
---urceolus prepared by insulation material, this urceolus upper end is bolted the rounded upper cover of downward projection prepared by insulation material, and the axial line place of this upper cover is provided with through hole;
---inner core prepared by insulation material, the upper end of this inner core is fixed on the upper end of this urceolus and is positioned at the inside of this urceolus, between the outer surface of this inner core and the inner surface of this urceolus, there is gap, simultaneously, the sidewall of this inner core is provided with helicla flute, and this spiral fluted lower end closed, upper end extend to the upper end of this inner core;
---brush body prepared by electrographite material with carbon element, this brush body is positioned at this inner core inside, and the projection that the circumferential surface of this brush body is provided with and this helicla flute matches;
---stage clip;
Described carbon brush component also comprises connector prepared by electrographite material with carbon element, this connector is positioned at this inner core and is positioned at the top of this brush body, simultaneously, the upper end of this connector is connected with wire, this wire extends up through this through hole, and the two ends of this stage clip act on respectively between this upper cover and this connector.
The upper surface of described connector is provided with annular groove, and the lower end of this stage clip withstands in this groove, and the degree of depth of this groove and width are all greater than the diameter of the spring body of this stage clip.
The advantage that the present invention has is: can be all the time keep comparatively good contacting with rotor, and its brush body and wire also have better electrical connection.The brush body of carbon brush component of the present invention constantly shortens along with the wearing and tearing of lower end, then moves down.Meanwhile, in the process moving down at it, projection slides in helicla flute, makes brush body be rotation shape.Like this, the lower end of this brush body remains round and smooth state but not arc surfaced, and then has ensured the good contact of this brush body and rotor.Meanwhile, the connection of brush body and wire realizes by the connector being pressed in closely all the time on this brush body, thereby has ensured that the good electrical of this brush body and wire is connected.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front view (internal structure half section, outer partial are analysed and observe) of embodiments of the invention.
In figure: 10, urceolus, 11, bolt, 12, upper cover, 121, through hole; 20, inner core, 21, helicla flute; 30, brush body, 31, projection; 40, connector, 41, wire, 42, groove; 50, stage clip.
Embodiment
Embodiment, as shown in Figure 1: carbon brush component, comprises the parts such as urceolus 10, inner core 20, brush body 30, connector 40, stage clip 50.Concretely:
This urceolus 10 is taked the insulation material preparations such as plastics.These urceolus 10 upper ends are connected with insulation material preparations such as taking equally plastics and the downward rounded upper cover 12 of projection by bolt 11, and the axial line place of this upper cover 12 is provided with through hole 121.
This inner core 20 is also taked the insulation material preparations such as plastics.The upper end of this inner core 20 is fixed on the upper end of this urceolus 10 and is positioned at the inside of this urceolus 10, between the outer surface of this inner core 20 and the inner surface of this urceolus 10, has gap.Meanwhile, the sidewall of this inner core 20 is provided with helicla flute 21, and the lower end closed of this helicla flute 21, upper end extend to the upper end of this inner core 20.
This brush body 30 is taked the preparation of electrographite material with carbon element.This brush body 30 is positioned at this inner core 20 inside, and the projection 31 that the circumferential surface of this brush body 30 is provided with and this helicla flute 21 matches., this projection 31 slides along this helicla flute 21.
This connector 40 is taked the preparation of electrographite material with carbon element.This connector 40 is positioned at this inner core 20 and is positioned at the top of this brush body 30.Meanwhile, the upper end of this connector 40 is connected with wire 41, and this wire 41 is connected to brace (not shown on figure) prepared by a copper material after extending up through this through hole 121.
The two ends of this stage clip 50 act on respectively between this upper cover 12 and this connector 40, thereby not only keep the excellent electric contact of this connector 40 and this brush body 30, and make this brush body 30 have all the time the trend to bottom offset.
Further say, the upper surface of this connector 40 is provided with annular groove 42, and the lower end of this stage clip 50 withstands in this groove 42, and the degree of depth of this groove 42 and width are all greater than the diameter of the spring body of this stage clip 50., this stage clip 50 can significantly not rotate this connector 40.
Operation principle of the present invention: under the effect of this stage clip, this brush body backward bottom offset that shortens, and this projection is subject to the restriction of this spiral fluted and makes this brush body rotating in bottom offset, then make the lower end of this brush body comparatively round and smooth all the time, and then can remain good contact with this rotor.Meanwhile, because the connection of this brush body and wire realizes by the connector being pressed in closely all the time on this brush body, ensured that the good electrical of this brush body and this wire is connected.
Combination carbon brush of the present invention in the preparation, first packs this brush body into inner core from top to bottom, and projection is entered in this helical groove.Then, this connector is packed in this inner core, then pack stage clip into this inner core, finally this upper cover is installed.
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.
