Description
Technical field
What the present invention relates to is a kind of electrode system of technical field of electricity, specifically a kind of positive electrode system of electro-rheological vibration isolator.
Background technique
Electrorheological fluid is a kind of SMART FLUID material.Under electric field action, it can change the solid state of class into by liquid state moment; After electric field was cancelled, it again can be promptly from the solid-state liquid state that returns to of class.Utilize the rheology controllable characteristics of current liquid, developed multiple electrorheological device, as electro-rheological vibration isolator, electrorheological clutch and electrorheological valve or the like.Wherein, electro-rheological vibration isolator has been widely used in the control of half active vibration.Up to the present, the required electric field strength of electrorheological fluid generation significant rheology effect is generally all more than 2000V/mm.With the spacing between the positive and negative electrode is that 0.5mm calculates, and the voltage between the positive and negative electrode reaches 1000V so.Under so high voltage, the Security and the integrity problem of the power supply connected system of electrode are very important.When the fixed-site of the positive and negative electrode of electro-rheological vibration isolator, lead can directly be drawn from the correct position of electrode place parts, and process treating such as sealing and insulation are relatively simple, the reliability height of electro-rheological vibration isolator.And when an electrode or two electrode movements, unreasonable Security and the integrity problem of just causing easily of the power supply mode of electrode.
Find through retrieval prior art, China Patent No.: 97200698.2, name is called the utility model patent of " cartridge type current transformation vibration damper ", and the whole piston rod of vibration damper is a positive electrode, and the stretching travel of piston rod is long more, the high voltage bare area is just big more, and this can cause the safety problem of getting an electric shock.On the other hand, the current transformation vibration damper in this patent makes the inner core positively charged by contacting of piston and inner core, because the free gap of piston and inner core can not guarantee the reliability that the two electrically contacts fully.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of positive electrode system of electro-rheological vibration isolator is provided, make its high-voltage part not exposed fully, electrical conductivity component reliably contacts, and has improved electro-rheological vibration isolator Supply Security and reliability.
The present invention is achieved by the following technical solutions, the present invention includes: electro-rheological vibration isolator lower cover plate, annular positive electrode sheet, positive electrode pedestal, metal disk, upper strata epoxy resin, draw wire bonds hole, Copper Foil and lower floor's epoxy resin.Its annexation is: the annular positive electrode sheet is welded on the positive electrode pedestal; The bottom of positive electrode pedestal is a spherical, constitutes dynamic and static electric contact respectively with metal disk on the electro-rheological vibration isolator lower cover plate; Metal disk closely is connected with Copper Foil below it; Copper Foil and electro-rheological vibration isolator lower cover plate keep reliable clearance for insulation, and fill with upper strata epoxy resin and lower floor's epoxy resin respectively in the gap, but are reserving wire bonds hole and the corresponding wire bonds face of drawing near electro-rheological vibration isolator lower cover plate edge.
Positive electrode pedestal spherical bottom is as movable contact among the present invention, and the central metal disk of electro-rheological vibration isolator lower cover plate is as stationary electrode, and the two constitutes a contact type electric contact-system.In electro-rheological vibration isolator, the positive electrode pedestal is subjected to the effect of vertical direction precompression, and the positive electrode pedestal is no matter translation or rotation are kept in touch with metal disk all the time and conducted electricity.Metal disk closely contacts with Copper Foil below it and conducts electricity.The long and narrow end of Copper Foil extends to the edge of electro-rheological vibration isolator lower cover plate.Copper Foil and electro-rheological vibration isolator lower cover plate keep reliable clearance for insulation, and except reserving the wire bonds hole in close lower cover plate edge section, fill with epoxy resin in all the other gaps.In actual the use, high-voltage conducting wires is welded to after the Copper Foil in the wire bonds hole, with rubbery stopper welding hole is clogged, and makes the people can't directly touch live part.
When the present invention powers, high-tension busbar is in welding hole and Copper Foil welding, and electric current is transmitted to Copper Foil from lead, is transmitted to metal disk by Copper Foil, be transmitted to the positive electrode pedestal by electrically contacting of metal disk and positive electrode pedestal again, be transmitted to each annular positive electrode sheet on the positive electrode pedestal at last.
Compared with prior art, electro-rheological vibration isolator positive electrode system among the present invention is reasonably selected insulating material for use, make full use of mechanical parts in the electro-rheological vibration isolator spatial relationship and be in contact with one another, change fixedlying connected of high-voltage conducting wires and positive electrode into flexible connection.Effect owing to be subjected to precompression as the positive electrode pedestal of movable contact can contact reliably with the metal disk under it.As the key components of electro-rheological vibration isolator, the upper surface of the electrode film of positive electrode system, positive electrode pedestal, metal disk is all in the cavity of electro-rheological vibration isolator among the present invention.The copper-foil conducting electricity under the metal disk and the lower cover plate of electro-rheological vibration isolator keep reliable clearance for insulation, are reserving beyond the electric wire face of weld near the lower cover plate edge section, and all fill with epoxy resin in its space, so lower cover plate positively charged not.High-voltage conducting wires is welded to after the Copper Foil in the wire bonds hole, and welding hole seals with rubbery stopper.As mentioned above, the present invention is electrically connected reliably, and being applied to electro-rheological vibration isolator does not have the positively charged exposed part that can allow the people touch later on, is safe to the user therefore.Security of the present invention and good reliability help the practicability and the industrialization of electrorheological vibration isolation.
