Description
Technical field
The utility model relates to circuit interconnection technique field, especially a kind of hollow 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, twisting and damage 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 finishing signal and power supply power.The mechanism of electric rotary connector exists than big difference according to the difference of the size of the occasion of its use and the electric current transmitted of wanting, existing a kind of electric rotary connector that transmits big electric current, comprise hollow slip ring axle sleeve, be provided with cable joint in the slip ring axle sleeve, the outer two ends of slip ring axle sleeve are arranged with bracing or strutting arrangement, be equipped with bearings between slip ring axle sleeve and the bracing or strutting arrangement, part on the slip ring axle sleeve between diaxon supports alternately is arranged with insulator and electric slip ring, insulation coordination between electric slip ring and the slip ring axle sleeve, be respectively equipped with corresponding brush the week of each electric slip ring to the periphery, brush is chip, insulation is fixed on the brush mounting panel, and the working end elasticity of brush is pressed the surface of touching at electric slip ring.Because this connector transmission is big electric current, require electric slip ring and brush that certain bearing capacity is all arranged, so need have certain contact width between the two, because of the contact-making surface between 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, processing and assembly difficulty are all bigger, thereby have influenced the production cost and the installation effectiveness of this electric connector; Brush must be pressed with bigger pressure and be touched on the electric slip ring surface simultaneously, even like this, brush also can not integral reliable contact on Width with electric slip ring, the problem that must produce local loose contact or not contact, bigger heat be will inevitably produce like this, thereby the transmission performance and the useful life of connector influenced.
The problem of heating when working in order to solve connector, application number is that 200910205329.0 Chinese patent discloses a kind of large-current electric rotary connector, this connector comprises hollow slip ring axle sleeve, be provided with the slip ring lead in the described slip ring axle sleeve, the two ends of slip ring axle sleeve are connected with bracing or strutting arrangement by bearing, described two bracing or strutting arrangements connect by the bridge joint beam, alternately be arranged with insulator and electric slip ring on the slip ring axle sleeve slip ring axle sleeve, insulation coordination between each electric slip ring and the slip ring axle sleeve, be respectively arranged with corresponding brushgear the week of each electric slip ring to the periphery, described brushgear comprises cylinder manifold and brush group, the brush group is by constituting to the brush monomer that the interval is laid on the described cylinder manifold along the electric slip ring axle sleeve, 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 and form rotational slide with it and cooperate.Described connector touches the pressure one by one that changes into by each brush monomer with original whole pressure and touches, and has reduced the width of brush monomer in the overall contact width that guarantees electric slip ring, has reduced the heating phenomenon that factors such as friction or loose contact cause.
Above-mentioned large-current electric rotary connector has solved the problem of rotary electric connector heating to a certain extent, but, some devices that need connect are when using rotary electric connector to connect, other parts (as cradle head etc.) need be installed in described slip ring axle sleeve, and the slip ring lead of above-mentioned large-current electric rotary connector is the inside that is arranged at its slip ring axle sleeve, therefore when needs are installed other parts in described slip ring axle sleeve, above-mentioned large-current electric rotary connector can not satisfy its requirement, makes its scope of application that limitation be arranged; In addition, since the brush lead of described large-current electric rotary connector be compile with described bridge joint beam on cylinder manifold on, in use, also need wiring between described cylinder manifold and garland lead and use equipment, strengthened staff's working strength so greatly, also made the difficult quality guarantee of wiring simultaneously.
In order to address the above problem, the patent No. is that 200820148717.0 Chinese patent discloses a kind of electric rotary connector, described electric rotary connector is by the inner rotary parts, jack shaft rotating parts and central shaft parts constitute, middle rotating shaft member rotates and is assemblied on the central shaft parts, the inner rotary parts rotate and are assemblied on the jack shaft rotating parts, at least one electric connector is installed on the rotating parts outside, at least one corresponding electric connector is installed on the jack shaft rotating parts, one end of described intermediate shaft part is provided with annular protrusion, and described electric connector is arranged on the outer ring surface of described annular protrusion; On the jack shaft rotating parts with the inner rotary parts in both assembly interface places corresponding contact slide ring portion and the contact brush parts of being equipped with.
Above-mentioned electric rotary connector has solved electric rotary connector wiring inconvenience to a certain extent, the problem that wiring quality is difficult to guarantee, but, because the electric connector on its intermediate shaft part is mounted on the end face bulge loop face of intermediate shaft part, the exit that is arranged at the lead on the described electric slip ring and is arranged at the lead on the described brush is all on the outer peripheral face of described electric rotary connector, so, when electric rotary connector need with the signal of telecommunication or power supply from electric rotary connector axially to conducting radially the time, above-mentioned electric rotary connector can not realize with use the equipment both direction (from electric rotary connector radially to axially) be connected, in addition, because described electric connector is installed on the outer peripheral face of electric rotary connector, increased the overall dimensions of electric separation rotary connector like this, and not attractive in appearance.
