Abstract
A wire holder comprises a metal inserts and an insulator. The metal inserts are embedded in the insulator by means of injection molding. The wire holder is characterized in that the metal inserts serve as wiring terminals of the wire holder, a insulating partition is disposed between each two metal inserts, and the insulating partitions and the insulator are made of same mold compound. Due to the fact that the metal inserts are embedded in the insulator by means of injection molding and the insulating partition which is made of mold compound reinforced by H-grade heat-resistant unsaturated polyester glass fiber is disposed between each two metal inserts, the insulator and the insulating partition are high in strength, good in high-temperature resistance, and can be subjected to insulation treatment along with stators. The mold compound is low in water absorption rate and good in weather fastness, and accordingly excellent electric insulating performance of the wire holder is guaranteed.
Description
Technical field
The utility model relates to a kind of junction block, particularly relates to a kind of high temperature resistant junction block take moulding compound as dielectric.
Background technology
Junction block generally all comprises metal inserted piece and insulator two parts, and existing motor adopts pottery or rubber with the junction block insulator more; Wherein adopt rubber to do junction block insulator water absorption rate higher, cause its electrical insulation properties relatively poor, and the physical and mechanical properties such as the hardness of rubber and intensity are also lower, can not satisfy the needs of motor, so now be the very few of motor junction block with rubber; And the junction block take pottery as insulator, intensity and the hardness of pottery are to satisfy the requirement of electrical machine insulation performance, but make insulator owing to adopting pottery, dielectric strength is to meet the demands by the distance of regulating between two binding posts, be that dielectric is air+pottery, but because the withstand voltage properties of air is unsettled, along with the rising of the humidity and temperature of air, the air insulation performance can worse and worse, therefore make the high-temperature insulation performance requirement of motor unstable.
Therefore, how to take into account physical and mechanical properties, resistance to elevated temperatures and the electrical insulation properties of insulator, to improve the combination property of junction block, become the problem that those skilled in the art need solve.
The utility model content
Technical problem to be solved in the utility model is: for physical and mechanical properties how to take into account insulator, resistance to elevated temperatures and electrical insulation properties, problem with the combination property that improves junction block proposes the better junction block of a kind of its performance of high temperature resistant electrical insulation properties.
In order to solve the problems of the technologies described above, implementer's case that the utility model proposes is: a kind of junction block, comprise metal inserted piece and insulator, and metal inserted piece is embedded in insulator; Its characteristics are, metal inserted piece is the binding post of junction block, is embedded in insulator by injection moulding, is provided with insulating barrier between every two metal inserted pieces, and insulating barrier and insulator adopt the identical molds plastic production.
Further, described metal inserted piece is the regular hexagon cylinder, and the side of cylinder is provided with the convex edge so that better contact with insulator.
Further, described insulating barrier is up-small and down-big cone tower structure, gives prominence on the upper surface of insulator.
Further, described insulating barrier extends to the side of insulator, forms the side projection.
Further, described insulator is to be formed by the moulding compound manufacturing that identical H level heat resisting unsaturated polyester glass fibre strengthens with insulating barrier.
The utility model has the advantage of: the utility model is by being injection-moulded in metal inserted piece in insulator, and the insulating barrier that the moulding compound that adopts H level heat resisting unsaturated polyester glass fibre to strengthen is made is set between two metal inserted pieces, make insulator and insulating barrier, not only intensity is high, and heat-resisting quantity is good, can carry out insulation processing with stator; This moulding compound water absorption rate is low, and weatherability is good, guarantees that junction block has excellent electrical insulation properties.

Embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is further detailed.
A kind of junction block comprises metal inserted piece 2 and insulator 1, and metal inserted piece 2 is embedded in insulator 1; Its characteristics are, metal inserted piece 2 is the binding post of junction block, be embedded in insulator 1 by injection moulding, and be provided with insulating barrier 3 between every two metal inserted pieces 2, and insulating barrier 3 adopts the identical molds plastic production with insulator 1.
Further, described metal inserted piece 2 is the regular hexagon cylinder, is provided with the convex edge so that better contact with insulator in the side of regular hexagon cylinder.
Further, described insulating barrier 3 is up-small and down-big cone tower structure, gives prominence on the upper surface of insulator.
Further, described insulating barrier 3 extends to the side of insulator, forms the side projection.
Further, described insulator 1 is to be formed by the moulding compound manufacturing that identical H level heat resisting unsaturated polyester glass fibre strengthens with insulating barrier 3.
