Abstract
A combined contact for a high-voltage isolating switch comprises a static contact and a contact finger. The combined contact is characterized in that: the contact finger has an integrated U-shaped copper bar structure; the static contact has an L-shaped copper bar structure; the middle part of the U-shaped copper bar of the contact finger is fixed on one surface of the L-shaped copper bar of the static contact; a sleeve is arranged between an upper finger sheet and a lower finger sheet of the U-shaped copper bar of the contact finger; the upper finger sheet and the lower finger sheet of the U-shaped copper bar of the contact finger are respectively provided with a groove; the upper finger sheet and the lower finger sheet of the U-shaped copper bar of the contact finger are respectively provided with a pressure plate; each pressure plate is provided with a projection which is adapted with the groove on the finger sheet; the projection on each pressure plate is arranged in the groove on the finger sheet; a bolt which penetrates through the pressure plates, the finger sheets and the sleeve is arranged; a spring sleeves the bolt; and the end of the bolt is tightened through a nut. According to the combined contact of the utility model, because the contact finger with the U-shaped copper bar structure and the static contact with the L-shaped copper bar structure are adopted, processing technique is greatly simplified, and low product cost is realized. The static contact is integrated with the contact finger, thereby realizing good contact surface and high heat radiating performance, and improving electrical performance.
Description
Technical field
The utility model relates to a kind of isolating switch, the combination contact that particularly a kind of isolating switch is used.
Background technology
The contact of high voltage isolator is the another parts of the key of isolating switch, and the contact-making surface quality of fixed contact and fingertip is related to the problem of temperature rise in the middle of routine use, and product quality, product are had to direct shadow noon useful life.As shown in Figure 1, the fingertip of line contact isolating switch is all a pair of use all the time, and the contacting of fingertip and fixed contact, major part is to contact with the fillet surface of endoporus on fixed contact machined surface by the lonely face in fingertip Ban garden, this has just increased the difficulty of processing.Fixed contact is through the bad casting of hair, metal cutting machine-shaping, particularly for the easier moulding of complex-shaped part.Easily occur the phenomenon such as shrinkage cavity and porosity and burning into sand but water foundry goods inside in pouring process, contact electric conductivity is reduced, loop circuit increases.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, and original structure is improved, and can simplify technique, has the features such as the low and good electric property of production cost.
Technical solution adopted in the utility model is:
The combination contact that a kind of high voltage isolator is used, comprise fixed contact 2 and fingertip 1, it is characterized in that the U-shaped structure of copper bar that fingertip 1 is integrated, fixed contact 2 is L-type structure of copper bar, the U-shaped copper bar middle part of fingertip 1 is fixed on a face of L-type copper bar of fixed contact 2 with bolt assembly 3, 11 of the sheets that refer to up and down of the U-shaped copper bar of fingertip 1 are provided with sleeve pipe 4, the sheet 11 that refers to up and down of the U-shaped copper bar of fingertip 1 is provided with groove 12, the sheet 11 that refers to up and down of the U-shaped copper bar of fingertip 1 is provided with pressing plate 5, pressing plate 5 is provided with and the plush copper 51 that refers to that groove 12 on sheet 11 is suitable, plush copper 51 on pressing plate 5 is positioned at the groove 12 referring on sheet 11, be provided with bolt 6 through pressing plate 5, refer to sheet 11 and sleeve pipe 4, on bolt 6, be arranged with spring 7, bolt 6 ends are tightened by nut 8.
The utility model is a kind of high voltage isolator (line contact) special combination contact, and fixed contact is formed through bending by moulding copper bar, and fingertip is U-shaped through striking out of simple mould by moulding copper bar.Its technical scheme is the size according to electric current, and fixed contact is selected ready-made red copper row, as long as be sawn into required size, installing hole on brill, has just become the fixed contact of required use by bending or not bending as required.The processing of fingertip, by original single-piece work, becomes two disjunctors and becomes U-shaped, raw material and original similar, and mould is also simple than original single-piece work model.
The utility model high voltage isolator composite type contact, is combined into entirety by bolt fixed contact and fingertip, and contact-making surface is good, perfect heat-dissipating, and due to the processing of moulding copper bar, loop resistance is little.Composite type contact manufacturing procedure is simple, and raw material are not also wasted, and production cost is low, is that the one of line contact high voltage isolation switch contact is selected.
The beneficial effects of the utility model are: technical solutions of the utility model, owing to adopting the fingertip of U-shaped structure of copper bar and the fixed contact of L-type structure of copper bar, have been simplified processing technology greatly, and production cost is low, fixed contact and fingertip are combined into entirety, contact-making surface is good, and perfect heat-dissipating has improved electric property.
