Technical field
The utility model relates to can rotate the slip ring field of transmitting the signal of telecommunication relatively, relates in particular to a kind of slip ring with temperature compensation function.
Background technology
Conducting slip ring belongs to and electrically contacts the application category that is slidingly connected; Be called again that collector ring, collector ring, rotation electricity are hinged, rotary electric connector, adapter etc.; 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.
In the prior art; The structural design of conducting slip ring product only is adapted at work under the normal temperature environment; In case ambient temperature is lower than the normal working temperature scope of slip ring product; Signals transmission in the conducting slip ring product can make the signal transmission fault because of product temperature is low excessively, causes conducting slip ring product cisco unity malfunction, the serious phenomenons such as poor electric contact or short circuit that also can occur between signal transmission failure, the reduction of slip ring rotation flexibility ratio, rotor and the stator.Under subzero 30 degree or lower special low-temperature working, existing conducting slip ring product can not satisfy the requirement of operating ambient temperature.
Summary of the invention
The utility model technical problem to be solved is to the problem that has poor electric contact between signal transmission fault, slip ring rotation flexibility ratio reduction and slip-ring rotor and the stator that exists when conducting slip ring is worked now under low temperature environment, provides a kind of and has been adapted at low temperature environment work, can regulate the slip ring with temperature compensation function of slip ring bulk temperature automatically.
For addressing the above problem, the technical scheme of the utility model is:
A kind of slip ring with temperature compensation function; Comprise the conducting slip ring body, the conducting slip ring body has an axle and and is arranged on the outer housing of axle, and the excircle of axle is provided with some conducting rings; Accommodate slip-ring brush between housing and the axle; Conducting ring and slip-ring brush electrically connect, and are provided with the Automatic Temperature Compensator that is used to regulate the slip ring temperature in the said conducting slip ring body, and the quantity of Automatic Temperature Compensator is at least one.
Preferably, said Automatic Temperature Compensator is arranged in the cavity of shell inner surface and the formation of axle outer surface through mounting bracket.
Preferably, said Automatic Temperature Compensator comprises heater and the thermostat that is used for control heater work, and heater and thermostat electrically connect, and said heater and thermostat electrically connect with conducting ring respectively.
Be compared to prior art; The slip ring with temperature compensation function of the utility model has been set up the Automatic Temperature Compensator that is used to regulate the slip ring temperature on the basis of conventional slip ring; Realize the possibility that slip ring is worked under low temperature environment, guaranteed the accessible transmission of the signal of telecommunication under the low temperature environment.Simultaneously, Automatic Temperature Compensator adopts the mode of slip ring in-line power, need not externally fed, installs simple and conveniently, can in having conventional slip ring now, install, and need not to replace entire product, has reduced use cost.
Description of drawings
Fig. 1 is the sectional structure sketch map that the utlity model has the slip ring of temperature compensation function.
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, the slip ring with temperature compensation function of the utility model comprises the conducting slip ring body that is used for transmission of electric signals and is used to regulate the Automatic Temperature Compensator of slip ring temperature.
Said conducting slip ring body can adopt the slip ring of conventional design in the prior art; The conducting slip ring body has an axle 1 and and is arranged on the housing 2 outside the axle 1; The excircle of axle 1 is provided with some conducting rings 3 and some dead rings 4, and every 3 adjacent of two conducting rings are provided with dead ring 4.Be provided with slip ring brush holder 5.1 in the cavity that said housing 2 and axle 1 form, slip-ring brush 5 is installed on the slip ring brush holder 5, conducting ring 3 electrically connects with slip-ring brush 5.Be respectively equipped with annular end cap 6 on two end faces of housing 2, form the space of a sealing between annular end cap 6, housing 2 and the axle 1, said housing 2 can relatively rotate with axle 1 and be connected.About the driving of housing 2 and axle 1 relative rotation motion of driving system and the working method of conducting slip ring is prior art, repeats no more at this.
Be provided with a plurality of Automatic Temperature Compensators in the said conducting slip ring body, Automatic Temperature Compensator is arranged on through mounting bracket in the cavity 7 that the outer surface of inner surface and the axle 1 of housing 2 forms, and mounting bracket is a slip ring brush holder 5.1 in the utility model.Said Automatic Temperature Compensator comprises heater 8 and the thermostat 9 that is used for control heater 8 work, and heater 8 electrically connects with thermostat 9, and thermostat 9 opens the light for temperature control, temperature and instruction heater 8 work that temperature control is opened the light and is used for the perception slip ring.Automatic Temperature Compensator adopts the mode of slip ring in-line power, need not externally fed, and heater 8 electrically connects with conducting ring 5 respectively with thermostat 9, realizes in-line power through conducting ring 5.The quantity that Automatic Temperature Compensator is installed can be confirmed by heat balance in the power of the size of slip ring volume, heater and the slip ring required heating time.
The utility model is set the temperature controlling range of thermostat 9 earlier in use, and thermostat 9 detects the temperature of slip ring internal cavities; When the inner real-time working temperature of slip ring less than temperature controlling range; The temperature control closure of opening the light then, heater 8 work, compensation slip ring temperature inside; When the slip ring temperature inside is higher than temperature controlling range, the then temperature control disconnection of opening the light, heater 8 quits work.Constantly add thermal compensation through heater 8, the slip ring temperature inside is in the righttest working temperature of slip ring, guarantee the accessible transmission of the signal of telecommunication in the low temperature environment.
