Abstract
The utility model provides a wiring terminal used for a high-voltage transformer. The wiring terminal used for the high-voltage transformer comprises an epoxy resin insulator and a conductive insert inlaid in the epoxy resin insulator. The conductive insert inlaid in the epoxy resin is composed of an inner insert, an outer insert, a connecting plate, a first nut and a second nut, wherein the inner insert is fixedly connected with one end of the connecting plate through the first nut, and the outer insert is fixedly connected with the other end of the connecting plate through the second nut. According to the wiring terminal used for the high-voltage transformer, because the inner insert and the outer insert are fixedly connected through the connecting plate and are not in the same contour, even when gap is formed between the insert of a conductive rod and insulator material, loosening will not happen, and thus the loosening of the insert of the conductive rod is solved fundamentally, the stability and the reliability of the product are improved, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to a kind of high-voltage mutual inductor binding post.
Background technology
In existing production process, the secondary wiring terminals that high-voltage mutual inductor is used is the mode that adopts poured with epoxy resin, brass conductive bar inserts and the epoxy resin insulation material of some are bonded together, in order to guarantee that conducting rod inserts and epoxy resin insulation material have enough adhesive strengths, avoid conducting rod inserts to rotate in epoxy resin.Our company is in the patent No. of front application: 201320011046.4, the utility model patent that patent name is " secondary wiring terminals that high-tension current inductor is used " discloses the secondary wiring terminals that a kind of high-tension current inductor is used, its content is, on brass conductive bar inserts, be provided with two annular grooves, to increase the bond area of inserts and epoxy resin.Although this patent makes moderate progress to the loosening problem of conducting rod inserts and epoxide resin material, but or cannot avoid loosening problem completely, owing to adopting a conducting rod inserts, the shrinkage of brass conductive bar inserts is different from the shrinkage of epoxide resin material, owing to expanding with heat and contract with cold, cannot solve the problems of the technologies described above at all.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of simple in structure, secondary wiring terminals that the reliable high-tension current inductor of steady quality is used.
The technical solution of the utility model is such realization: a kind of high-voltage mutual inductor binding post, comprise epoxy resin insulator and be embedded in the conductive insert in epoxy resin insulator, the described conductive insert being embedded in epoxy resin is made up of embedded component, externally inlaid part, connecting plate, the first nut and the second nut, embedded component is fixedly connected with one end of connecting plate by the first nut, and externally inlaid part is fixedly connected with the other end of connecting plate by the second nut.
Further, the distance between described embedded component and externally inlaid part is 20-30mm.
Further, the distance between described embedded component and externally inlaid part is 25mm.
Beneficial effect: the utility model is owing to adopting embedded component to be fixedly connected with by connecting plate with externally inlaid part, and embedded component and externally inlaid part be not on same contour, even conducting rod inserts and insulator material production gap, can not produce loosening phenomenon yet, thereby fundamentally solve the loosening phenomenon of conducting rod inserts, improve stability, the reliability of product, extended the useful life of product.
Accompanying drawing explanation

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
As shown in Figure 1, a kind of high-voltage mutual inductor binding post, comprise epoxy resin insulator 1 and be embedded in the conductive insert in epoxy resin insulator, the described conductive insert being embedded in epoxy resin is made up of embedded component 2, externally inlaid part 3, connecting plate 4, the first nut 5 and the second nut 6, embedded component 2 is fixedly connected with one end of connecting plate 4 by the first nut 5, and externally inlaid part 3 is fixedly connected with the other end of connecting plate 4 by the second nut 6.
Further, the distance between described embedded component 2 and externally inlaid part 3 is 20-30mm.
Further, the distance between described embedded component 2 and externally inlaid part 3 is 25mm.
In use, wire need to be connected on the terminal of embedded component, externally inlaid part, and need to be fastening with spanner, owing to there being certain moment, and embedded component, externally inlaid part connect by connecting plate, and embedded component, externally inlaid part be not on same axis, even if use larger power, embedded component and externally inlaid part also can not rotate, loosening phenomenon, thereby improve the stability of product, increased the useful life of product.
It should be noted that, above-described execution mode is explanation to technical solutions of the utility model and unrestricted, person of an ordinary skill in the technical field be equal to replace or make according to prior art other revise as long as no the thinking and the scope that exceed technical solutions of the utility model, within all should being included in the desired right of the utility model and scope.
