Abstract
The utility model provides a connecting component for an oil sealing device. The connecting component comprises a base plate, a boss, a fixing insert and a connecting insert, wherein the fixing insert is embedded into the base plate, the boss is arranged on the outer surface of the base plate, the connecting insert is inlaid into the boss, the base plate, the boss, the fixing insert and the connecting insert are integrally die-cast, and both the boss and the base plate are made of DMC (dimethyl carbonate) insulating oil-resistant materials. The connecting component is fine in leakage resistance, particularly suitable for electrical connection of internal and external components of an oil-immersed transformer or a power capacitor, and also suitable for other similar places needing oil sealing.
Description
Technical field
The utility model relates to a kind of connecting part, specifically a kind of connecting part that is used for oil seal equipment.
Background technology
At present; For oil-filled transformer, power capacitor and other oil seal equipment; When inner member need be electrically connected with outer member or equipment, often connection cable or copper binding post are cast in the equipment top cover with epoxy resin or other insulating material, when normal temperature, can guarantee non-leakage; But when uniform temperature is arrived in the oily temperature rise in the oil seal equipment; Because connection cable or copper binding post are different with epoxy resin and top cover thermal coefficient of expansion, its faying face can form fine gap, easily seepage oil.
The utility model content
The purpose of the utility model is to provide a kind of connecting part that is used for oil seal equipment, thereby solves the foregoing problems that exists in the prior art.
To achieve these goals, the technical scheme of the utility model employing is following:
A kind of connecting part that is used for oil seal equipment comprises substrate, boss, fixedly inserts and wiring inserts; Said fixedly inserts is embedded in the said substrate, and said boss places the outer surface of said substrate, and said wiring inserts is embedded in the said boss; Said substrate, said boss, said fixedly inserts and the moulding of said wiring inserts integral die-cast; The material of said boss and the material of said substrate are DMC insulation oil resisting material.
Preferably, the surface of said wiring inserts is provided with annular knurl and grooving, and surperficial bottom-up 2/3～4/5 place of said wiring inserts is wound with silica gel.
Preferably, the material of said substrate, said boss is DMC bulk unsaturated polyester die plastic.
Preferably, two indent of said wiring inserts, the surface of said indent is provided with screw thread.
The beneficial effect of the utility model is:
The connecting part that is used for oil seal equipment of the utility model; Because of wiring insert surface annular knurl and grooving; Fundamentally avoided die casting tightly not form the capillary seepage; And twining proper silica gel at 2/3 place, silica gel and DMC bulk unsaturated polyester die plastic shrinkage are basic identical, avoid the seepage that causes because of the shrinkage difference.There is screw thread at wiring inserts two, is convenient to wiring, but the centre is not penetrating, prevents leakage of oil.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.Should be appreciated that embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
A kind of connecting part that is used for oil seal equipment of the utility model shown in Fig. 1-5; Comprise substrate, boss, fixedly inserts and wiring inserts; Said fixedly inserts is embedded in the said substrate, and said boss places the outer surface of said substrate, and said wiring inserts is embedded in the said boss; Said substrate, said boss, said fixedly inserts and the moulding of said wiring inserts integral die-cast; Said boss, said substrate are formed by DMC insulation oil resisting material integral die-cast.The precalculated position that earlier said wiring inserts and said fixedly inserts is positioned over mould during fabrication again in mould filling DMC bulk unsaturated polyester die plastic use mould then, the integral die-cast moulding.When the connecting part of the utility model is installed, through said fixedly inserts with its sealing and fixing on the housing of said oil seal equipment.The outer surface that said wiring inserts and said boss join is provided with annular knurl and grooving, makes wiring inserts and boss, substrates tightr, has fundamentally avoided die casting tight and form the capillary seepage; Bottom-up 2/3～4/5 place of the outer surface of said wiring inserts is wound with proper silica gel, because the shrinkage of silica gel and DMC bulk unsaturated polyester die plastic is basic identical, thereby has avoided the seepage that causes because of the shrinkage difference.Two indent of said wiring inserts, the surface of said indent is provided with screw thread, is convenient to wiring, but the indent at two is not communicated with, in case leak-stopping is oily.DMC insulation oil resisting material in the utility model is a DMC bulk unsaturated polyester die plastic.
The connecting part that the utility model provided can manufacture multiple shape to adapt to different oil seal equipment according to the different application scene.
Through as above technical scheme, the utility model has been realized following beneficial effect:
The connecting part that is used for oil seal equipment of the utility model; Because of wiring insert surface annular knurl and grooving; Fundamentally avoided die casting tightly not form the capillary seepage; And twining proper silica gel at 2/3 place, silica gel and DMC bulk unsaturated polyester die plastic shrinkage are basic identical, avoid the seepage that causes because of the shrinkage difference.There is screw thread at the inner two of wiring inserts, be convenient to wiring, but the centre is not penetrating, prevents leakage of oil.
The English full name of DMC is " dough moulding compound "; Chinese is mainly used in industry, electrical equipment, building materials etc. for " bulk unsaturated polyester die plastic ", have general, electrical equipment, heat-resisting, flame retardant rating other.The BMC-bulk of title moulding compound is also arranged.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be looked the protection range of the utility model.
