Abstract
The utility model relates to a novel electric brush which comprises brush wires bundled by a plurality of metal fiber wires and a hollow metal brush tube, wherein the brush wires are plugged into the hollow metal brush tube and are in soldering connection with the hollow metal brush pipe. According to the novel electric brush disclosed by the utility model, the metal fiber wires replace a traditional blocky electric brush, so that the surface contact between the electric brush and a conducting slip ring is changed into point contact and further the friction resistance and friction noise between the electric brush and the conducting slip ring are greatly reduced and the wear is reduced. Meanwhile, due to the adoption of the point contact mode, a dynamic contact resistance value is reduced, the service life of the electric brush and the service life of the conducting ring are prolonged and the maintenance-free effect within the design life period can be achieved. The novel electric brush disclosed by the utility model is simple in structure, convenient in processing and manufacturing and low in cost; the brush wires and the metal brush pipe in the electric brush are welded; the contact between the electric brush and the conducting slip ring is realized by adopting the elasticity of the electric brush; the pressure between the electric brush and the conducting slip ring can be adjusted according to actual conditions; and high contact reliability is obtained.
Description
Technical field
The utility model relates to electrical transmission technical field in the slip ring, relates in particular to a kind of novel brush that is used for slip ring conducting ring electrical transmission.
Background technology
Conducting slip ring belongs to and electrically contacts the application category that is slidingly connected; Be called collector ring, rotary electric connector etc. again; Be the accurate electric device of realizing power, signal and data interrupted transmission between two relative rotating mechanisms, be particularly suitable for 360 ° of equipment that rotate and need to realize signal of telecommunication interrupted transmission continuously.Wherein, two relative rotating mechanisms are called stator and rotor respectively, and brush can be designed to rotor or stator respectively according to the needs of product, is used to transmit the signal of telecommunication of conducting ring.In the prior art, the slip ring product all adopts traditional block brush structure, and block brush comprises black lead brush and metal block brush; Both utilize the elastic force of outside flexible member to make it to contact with the conducting ring surface, and the way of contact is the face contact, and frictional resistance is big; Noise is big, serious wear, and the dynamic contact resistance value is big; And need periodic cleaning or change brush, cause damage of product because of loose contact causes sparking ablation conducting ring or brush easily.
Summary of the invention
The utility model technical problem to be solved is the problems referred to above that in use exist to existing conducting slip ring brush, and the novel brush that a kind of frictional resistance is little, wearing and tearing are little, dynamic contact resistance is little, the life-span is long is provided.
For addressing the above problem, the technical scheme of the utility model is:
A kind of novel brush, said brush comprise the brush silk and hollow metal brush pipe that are become by number of metal filament boundling, and said brush silk is plugged in the hollow metal brush pipe, and brush silk and hollow metal are brushed and managed scolding tin and be connected.
Preferably, the said metal fiber wire specification that is plugged in the hollow metal brush pipe is identical, and the silk footpath of metal fiber wire is 0.1-0.3mm.
Be compared to prior art, the novel brush of the utility model adopts metal fiber wire to replace traditional block brush, brush is contacted with the face of conducting slip ring become a contact; Frictional resistance and frictional noise between brush and the conducting slip ring have been reduced greatly; Reduced wearing and tearing, simultaneously, the mode of some contact reduces the dynamic contact resistance value; Increase the useful life of brush and conducting ring, and in phase designed life, can reach non-maintaining effect.The utility model is simple in structure, and brush silk in the brush and metallic brush pipe adopt welding manner, convenient processing and manufacture; Cost is low; And brush and contacting of conducting slip ring be to adopt the elastic force of self to realize that pressure each other can be adjusted according to actual conditions, and contact reliability is high.
Description of drawings
Fig. 1 is the structural representation of the novel brush of the utility model.
Fig. 2 is the sectional structure sketch map of the novel brush of the utility model.
Fig. 3 is the user mode structural representation of the novel brush of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment further explain the utility model, but the protection range of the utility model is not limited to this.
With reference to Fig. 1-2, the novel brush of the utility model comprises the brush silk 1 and hollow metal brush pipe 2 by number of metal filament 1.1 boundlings one-tenth.Said brush silk 1 is plugged in the hollow metal brush pipe 2, and brush silk 1 is connected with hollow metal brush pipe 2 scolding tin in the grafting scope, and brush silk 1 and hollow metal brush pipe 2 are electrically connected.The said specification that is plugged on the metal fiber wire 1.1 in the hollow metal brush pipe 2 is identical, and the silk footpath of metal fiber wire 1.1 is 0.1-0.3mm, in actual use, and the brush that can design different size by the size and the physical dimension requirement of conducting slip ring electric current.
With reference to Fig. 3; The utility model is when user mode; The hollow metal brush pipe 2 of novel brush is installed on the brush carrier 4 of insulation; Brush silk 1 contact with conducting ring 6, brush and manage 2 installation site or the installation site of brush and conducting ring 6 changes the contact pressure between brush and the conducting ring 6 through regulating brush carrier 4 and hollow metal.Hollow metal brush pipe 2 upper ends of brush are provided with draws lead 5, is provided with in the conducting ring 6 and draws lead 6.1.When brush and conducting ring 6 relatively rotated, the signal of telecommunication that can will draw lead 6.1 transfers to drew the signal of telecommunication that maybe will draw lead 5 on the lead 5 and transfers to and draw on the lead 6.1, realizes signal of telecommunication transmission.
Claims (2)
1. novel brush; It is characterized in that; Said brush comprises that by the brush silk (1) of number of metal filament (1.1) boundling one-tenth and hollow metal brush pipe (2), said brush silk (1) is plugged on the hollow metal brush and manages in (2), and brush silk (1) is connected with hollow metal brush pipe (2) scolding tin.
