Because the contact area of the brush wire is tile-shaped, the abrasion can be reduced, the generation of bounce during the operation of the slip ring can be avoided, and the transmission signal can be stably output.

Description

Electric brush wire structure and electric brush module structure

Technical Field

The utility model relates to an electric brush modular structure adopts tile form brush silk, can reduce wearing and tearing, and the spring when effectively avoiding the sliding ring function produces.

Background

the matching of the collecting ring and the electric brush can be applied to a circuit system which requires continuous rotation and needs to transmit power and/or electronic signals, so that the sprain of a lead in the rotation process is avoided. Since the brushes must be in constant contact with the metal ring to ensure the transmission of the power and/or electronic signals, their strength must be maintained at a certain level. In addition, when a metal wire is used as a brush, the contact pressure is light, the brush is easily worn, and the jumping of the pin causes a phenomenon that the transmission signal output is unstable.

SUMMERY OF THE UTILITY MODEL

in view of this, the utility model provides an electric brush silk structure has one and links section and two free sections and extends from the relative both ends of linkage section, and its characterized in that, the one end that the linkage section was kept away from to the free end is equipped with the metal ring contact of contact area and collecting ring, and contact area's vertical section is the tile shape of evagination indent.

The tile-shaped structure enables the surface of the contact area and the metal ring to have at least two contact positions, so that the generation of bouncing during the operation of the slip ring can be effectively avoided, and the instability of contact resistance is reduced. Moreover, the tile-shaped structure makes the contact area wear-resistant, prolongs the service life, has small ripple in contact with the collector ring, and reduces the generation of noise. Furthermore, precious metal can be plated only on the contact area of the brush wire, so that the cost pressure and the material waste are greatly reduced.

In addition, be the fillet between the section of linking of brush silk structure and the free segment, and this fillet is not wrapped by the fixing base when the brush modularization, and the one end that the connecting segment was kept away from to the free segment is equipped with the outside foot of bending, can control the angle and the coefficient of elasticity of free segment, control and the pressure of conducting ring contact, reduce the resistance of contact.

The utility model provides a brush modular structure again contains foretell brush silk and is the separation range to and have a fixing base of closed profile, the relative two ends of brush silk linkage segment side by side of cladding, but the linkage segment mid portion of fretwork brush silk makes the mid portion of fretwork can the electric connection wire, follows a fixing base side and sets up side by side.

Other functions and embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Detailed Description

For the purpose of clearly illustrating the embodiments, structures and effects achieved by the present invention, the following description is made with reference to the drawings:

Referring to fig. 1, a brush wire structure is shown, which has a connecting section 11 and two free sections 12 extending from two opposite ends of the connecting section 11, wherein one end of the free end 12 away from the connecting section 11 is provided with a contact area 15 contacting with a metal ring of a collector ring 40 (shown in fig. 4), and a longitudinal section of the contact area 15 is in a shape of a convex tile.

Fig. 1 shows a schematic vertical cross-sectional view of a contact region 15 at the lower left of fig. 1, the contact region 15 has a contact surface 151 contacting the slip ring 40 and an outer side surface 152 opposite to the contact surface 151, the contact surface 151 is recessed corresponding to the arc-shaped surface of the slip ring 40, and at least two contact positions are formed between the contact surface 151 and the slip ring 40, so as to reduce instability of contact resistance. When one of the contact locations wears, the recessed portion of the contact surface 151 can still create a new contact location, providing wear-resistant performance and increased service life. On the other hand, the outward surface 152 protrudes outward to provide adequate structural strength, so that the brush wire structure has less ripple in contact with the slip ring 40, reducing noise generation. In addition, contact surface 151 can be the sunk structure that the good precious metal coating 16 of electric conductivity formed, compare with the whole plating precious metal of brush silk among the prior art, the utility model discloses a manufacturing cost is lower.

In this embodiment, a fillet 13 is formed between the connection section 11 and the free section 12, and an outward (away from the collecting ring direction) bending pin 14 is disposed at an end of the free section 12 away from the connection section 11, so as to control an angle and an elastic coefficient of the free section, and a contact pressure between the brush wire 10 and the conductive ring, thereby reducing a contact resistance.

Referring to fig. 2 and 3, a brush module structure is shown, which includes a plurality of brush wires 10 arranged in a spaced manner and a fixing base 20, wherein the fixing base 20 has a rectangular closed contour, covers two opposite ends of a connecting section 11 of the brush wires 10, and hollows out a middle portion of the connecting section 11 of the brush wires 10. In this embodiment, the fixing base 20 does not cover the fillet structure, so as to control the contact pressure between the contact area 15 and the conductive ring, and the middle part of the connection section 11 of the brush wire 10 is a plane, and the hollow middle part can be used for electrically connecting wires, so that the wires (not shown) are electrically connected to each brush wire 10 one by one, and a plurality of wires can be stacked in a single layer perpendicular to the brush wires 10 and arranged on the plane, thereby reducing the mutual interference or ignition in signal generation.

The above-described embodiments and/or implementations are merely illustrative of preferred embodiments and implementations for implementing the technology of the present invention, and are not intended to limit the implementations of the technology of the present invention in any way, and those skilled in the art can make modifications or changes without departing from the scope of the technology disclosed in the present invention.
