Abstract
The invention relates to a large-current electric rotary connector, which comprises a slip-ring shaft; insulators and electric slip-rings are alternately sheathed on the slip-ring shaft; each electric slip-ring is matched with the slip-ring shaft in an insulating way; the circumferential periphery of each electric slip-ring is provided with a corresponding electric brush device respectively; the electric brush device comprises a confluence plate and an electric brush group; the electric brush group consists of electric brush monomers that are axially and intermittently arranged on the confluence plate; each electric brush monomer is conducted with the confluence plate; and the working end of each electric brush monomer is elastically pressed and contacted on the surface of the electric slip-ring corresponding to the electric brush device so as to form a rotary sliding contact matching. The connector changes the existing whole press-contact into press-contact of each electric brush monomer, thus ensuring the total contact width of the electric slip-ring; as the width of the electric brush monomer is greatly reduced, small press-contact force is needed to ensure the reliable contact between the electric brush monomer and the electric slip-ring, thereby greatly reducing the heat generated due to excessively large friction force and bad contact.
Description
Technical field
The present invention relates to a kind of electric rotary connector.
Background technology
Electric rotary connector be a kind of can be at the electric connector of transmission signals under the rotary state and power supply power, in rotary course, the damage of twisting property can not take place in the cable that is used for transmission signals and power supply power.The main composition member of electric rotary connector is electric slip ring and brush, utilizes the relative rotational slide between electric slip ring and the brush to contact the transmission of accomplishing signal and power supply power.The structure of electric rotary connector exists bigger difference according to its employed occasion is different with the different of want electric current transmitted size; Existing a kind of electric rotary connector that transmits big electric current comprises hollow slip ring axle, is provided with cable joint in the slip ring axle; The outer two ends of slip ring axle are arranged with bracing frame; Be equipped with bearings between slip ring axle and the bracing frame, the part on the slip ring axle between two bearings supports alternately is arranged with insulator and electric slip ring, is insulation coordination between electric slip ring and the slip ring axle; Be respectively equipped with corresponding brush the week of each electric slip ring to the periphery; Brush is chip, and insulation is fixed on the brush mounting panel, and the working end elasticity of brush is pressed and touched the surface at electric slip ring.Because this connector transmission is big electric current; Require electric slip ring and brush all should have certain current capacity; So need have certain contact width between the two, because of the contact-making surface of each electric slip ring in this connector and each brush all is a contact-making surface integral body, broad, if will guarantee both whole contacts on Width; Not only require both adding the form accuracy that reaches higher man-hour; And when assembling is also higher to the position accuracy demand of brush, and processing and assembly difficulty are all bigger, certainly will have influence on cost and efficient; Brush must be pressed with bigger pressure and touched on the electric slip ring surface simultaneously; Even like this; Brush also can not integral body contact on Width with electric slip ring reliably; Must there be local loose contact perhaps not contact, produces bigger heat, thereby influence the transmission performance and the serviceability of connector so must cause when work; In addition, this whole contact matching structure makes that also the wearing and tearing of brush are inhomogeneous, can shorten the useful life of brush.
Summary of the invention
The purpose of this invention is to provide a kind of large-current electric rotary connector, to solve the existing large-current electric rotary connector big problem of caloric value between brush and electric slip ring in use.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of large-current electric rotary connector, comprise the slip ring axle, and alternately be arranged with insulator and electric slip ring on the slip ring axle; Insulation coordination between each electric slip ring and the slip ring axle; Be respectively equipped with corresponding brushgear the week of each electric slip ring to the periphery, said brushgear comprises cylinder manifold and brush group, and the brush group is made up of the brush monomer that is laid on the cylinder manifold along the electric slip ring axially spaced-apart; Each brush monomer is connected with the cylinder manifold conducting, the equal elasticity in the working end of each brush monomer press touch with the surface of the corresponding electric slip ring of place brushgear on, form the rotational slide contact matching with it.
Said each electric slip ring surface be provided with corresponding brushgear on each brush monomer one to one, the chute of rotational slide contact matching.
Be equipped with insulating case between the endoporus of each electric slip ring and the slip ring axle, each insulating case is one-body molded with the insulator of the same side that is positioned at pairing electric slip ring.
All be arranged with two cover brushgears the week of each electric slip ring to the periphery.
Each brush monomer in the said brushgear is arranged in parallel, and each brush monomer all has two working ends, and two working ends are the splayed symmetric arrangement.
The cylinder manifold of said brushgear is provided with two cable connectors.
The whole slice structure that the present invention will have brush now changes into by several conductings and is connected in the brush monomer on the cylinder manifold; Each brush monomer is connected in parallel along the axially-aligned of electric slip ring and through cylinder manifold, is connected with outside cable by cylinder manifold during use, simultaneously; The working end of each brush monomer is all pressed and is touched on electric slip ring; Form the rotational slide contact matching with electric slip ring, this connector has changed original brush whole pressure electric shock slip ring on the brush width direction by each brush monomer into has pressed the electric shock slip ring one by one, has both guaranteed the overall contact width of electric slip ring; That is to say the current capacity when having guaranteed connector work; As far as single brush monomer,, only need to guarantee that with less pressure touch the brush monomer contacts with electric slip ring reliably because of the width of brush monomer reduces significantly; Thereby work the time can significantly reduce original whole chip brush and heat because of exist loose contact part produce excessive because of frictional force, thereby improves the transmission performance and the serviceability of connector.In addition, brush monomer in a narrow margin guarantees easily evenly to press with electric slip ring and touches, and the wearing and tearing of brush monomer will be comparatively even, and the degree of wear of brush monomer also can reduce along with pressing reducing of touch to some extent, makes be able to prolong the useful life of brush monomer; Simultaneously, brush monomer in a narrow margin when form accuracy that adds man-hour and general assembly and the positional precision of electric slip ring all be easy to guarantee, reduced the difficulty of processing and assembling, and then reduced cost, improved production efficiency.
The present invention is convenient to the location and the assembling of each brush monomer being provided with on the surface of electric slip ring and brush monomer one to one behind the chute.Insulating case in the electric slip ring endoporus adopts with corresponding insulator one-body molded as a whole, has made things convenient for the general assembly of processing and connector.Two cable connectors are set on the cylinder manifold of brushgear; Adopt two-way cable transmission current; Compare with a route cable, under the prerequisite that does not reduce current capacity, can reduce the diameter of cable; The cable that connects usefulness can more softly, better be installed, can guarantee the reliable connection of cable better.
