Abstract
Generally speaking, the overlapping area formed between a static contact mounted inside a contact box and a bus is very small, and the contacting is not firm so that the resistance at the contacting place is increased, the heating and the rising of temperature are caused, the insulation of the contact box is damaged, and consequently, severe accidents are triggered. The utility model provides a heat-dissipation contact box structure, comprising a bus, a box shell, an embedding hole, a contacting plate, and a through hole, wherein the embedding hole is located on the box shell; the through hole is arranged on the contacting plate; the contacting plate contacts with the embedding hole; a screw fixes the bus through the through hole of the contacting plate and the embedding hole; and heat-dissipation holes are located on a cylindrical body of the box shell. According to the utility model, by fixing the bus with the contacting plate, the extrusion area is greatly increased; the problem of contact failure is solved; the heat-dissipation function is additionally provided at the same time; and the heat-dissipation contact box structure is stable and reliable.
Description
Technical field
The utility model relates to contact box and makes the field, relates in particular to a kind of heat radiation contact box structure.
Background technology
Contact box is insulating element commonly used in high-tension switch cabinet, the middle-placed switch cabinet.For contact box, the quality of its insulation property is very important, accidentally leads to easily serious accident.In general, the overlap joint area that is installed in the fixed contact of contact box and bus is very little, and contact insecure, can cause like this contact position resistance to increase, if causing the heating heat can not in time distribute, also can cause the rising of temperature, can cause the destruction of contact box insulation, thereby cause serious accident.
The utility model content
For existing technical problem, the utility model provides a kind of heat radiation contact box structure, can effectively solve the problems such as fixed contact and busbar shiplap joint area are little, loose contact, can realize good heat radiation simultaneously.To achieve these goals, technical solution adopted in the utility model is, a kind of heat radiation contact box structure comprises bus, box shell, inlaid hole, contact plate, through hole, louvre, and wherein, inlaid hole is positioned on the box shell; Dig on the contact plate through hole is arranged; Contact plate and inlaid hole contact; Screw is realized the fixing of bus by through hole and the inlaid hole of contact plate; Louvre is positioned on the cylindrical shell of box shell.
A kind of heat radiation contact box structure that the utility model provides by allowing bus and contact plate fix, has greatly improved and has extruded area, has solved the problem of loose contact, has increased simultaneously heat sinking function, stable, reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 bus, 2 box shells, 3 inlaid holes, 4 contact plates, 5 through holes, 6 louvres
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model, comprises bus 1, box shell 2, inlaid hole 3, contact plate 4, through hole 5,6 louvres, and wherein, inlaid hole 3 is positioned on the box shell 2; Dig on the contact plate 4 through hole 5 is arranged; Contact plate 4 and inlaid hole 3 contact; Screw is realized the fixing of bus by through hole 5 and the inlaid hole 3 of contact plate 4, and louvre 6 is positioned on the cylindrical shell of box shell 2.A kind of contact box structure that the utility model provides by making bus 1 fixing with contact plate 4, has greatly improved and extruded area, has solved the problem of loose contact, has increased simultaneously heat sinking function, and is stable, reliable.
