Abstract
The utility model discloses a transformer wiring terminal connecting mechanism. The transformer wiring terminal connecting mechanism comprises a rubber mat, an elastic pressing mechanism and a nut, wherein the rubber mat, the elastic pressing mechanism and the nut sequentially penetrate into a sleeve. The nut is provided with a sleeve cap, a skirt body of the sleeve cap covers the rubber mat, the elastic pressing mechanism comprises an arc-shaped insulating gasket, an elastic component and an insulating flat cushion, the lower surface of the arc-shaped insulating gasket is arranged into an arc shape, and a boss is arranged on the upper surface of the arc-shaped insulating gasket. The elastic pressing mechanism is utilized to store elastic potential energy, the rubber mat can be pressed down to seal the sleeve when the rubber mat is subject to chilling shrink, the sleeve is always kept sealed and is in good condition, the problem of oil leakage or oil inflow caused by the fact that slits are easily generated in the rubber mat under the effect of expanding with heat and contracting with cold is effectively solved, the elastic pressing mechanism is protected through the skirt body of the sleeve cap, impurities are also prevented from entering and blocking normal motion of the elastic pressing mechanism, the lower surface of the arc-shaped insulating gasket is arranged into the arc shape, the contact is full, and the boss on the upper surface facilitates installation of the elastic component. The transformer wiring terminal connecting mechanism is simple in structure and convenient to use and is universally popularized and used conveniently.
Description
Technical field
The utility model belongs to electric power safety technical field of construction, particularly a kind of transformer wiring terminal bindiny mechanism.
Background technology
In power circuit, the porcelain vase upper end of existing transformer seals by rubber cushion, insulator, pad and nut, but because rubber cushion easily and between porcelain vase produces gap under the effect of expanding with heat and contract with cold, and then cause the Harms such as leakage of oil, water inlet, greatly affect the safe operation of electrical network.Application number: 201110030511.4 Chinese invention patent discloses a kind of all-insulation transformer, comprise the porcelain vase arranging on casing and cabinet exterior, primary connection end and secondary connection end, once described, secondary connection end is connected with outlet cable respectively, on cabinet exterior, be provided with the pedestal I that the cast of insulative water-proof material forms, porcelain vase, the line place of primary connection end and primary connection end and outlet cable is fixed in pedestal I by cast, pedestal I is sleeved in metal shell, metal shell is weldingly fixed on casing, the cable outlet end of metal shell is provided with sealing ring and blind flange, the line place of the porcelain vase of transformer of the present invention, primary connection end and primary connection end and outlet cable is all fixed in pedestal by cast, live part and the external world of high pressure grade are isolated completely, when secondary connection end is also closed in metal shell or while being fixed in pedestal by cast, all live parts of transformer are all isolated from the outside, reach two-stage live part and all realize the effect of totally-enclosed all insulation, use more safe and reliable.But described all-insulation transformer complex structure, it is unfavorable to promote.
Utility model content
The utility model, in order to address the above problem, provides a kind of simple in structure, connects safe and reliable transformer wiring terminal bindiny mechanism.
For achieving the above object, the technical solution adopted in the utility model is: a kind of transformer wiring terminal bindiny mechanism, comprise the rubber cushion, elastic hold-down mechanism and the nut that are placed through successively on sleeve pipe, on described nut, cap bag is set, the skirt body of described cap bag covers described rubber cushion.
Described elastic hold-down mechanism comprises arc insulation spacer, elastic component and insulation plain cushion, and described arc insulation spacer bottom connects described rubber cushion, and described insulation plain cushion is pressed in described nut below.
Described arc insulation spacer lower surface is set to arc, and upper surface arranges boss.
Described elastic component is set to holddown spring.
The utility model by arranging rubber cushion on sleeve pipe, elastic hold-down mechanism and nut, utilize elastic hold-down mechanism storage elasticity potential energy, in rubber cushion shrinkage, rubber cushion can be pressed down to Sealed casing pipe, remain that sealing is intact, effectively avoid rubber cushion under the effect of expanding with heat and contract with cold, easily to produce the problem that leakage of oil or water inlet are caused in gap, on described nut, cap bag is set, the skirt body of described cap bag covers described rubber cushion, avoid described elastic hold-down mechanism lost of life under rainwater and the sun, also prevent that foreign material from entering the proper motion that blocks described elastic hold-down mechanism, described elastic hold-down mechanism comprises arc insulation spacer, elastic component and insulation plain cushion, two ends good insulating effect, guarantee to connect up and down reliable, using described arc insulation spacer as movable end, described arc insulation spacer lower surface is set to arc, contact fully, upper surface arranges boss, be convenient to install elastic component, , holddown spring.The utility model is simple in structure, easy to use, is convenient to generally promote the use of.
