Abstract
The utility model discloses a low voltage busbar terminal, which comprises an insulation body, through which a conductive bar penetrates. The conductive bars at the two ends of the insulation body are fixedly connected with a pressure plate on which a groove for installing a cable wire is arranged. The insulation body is in an umbrella structure. The utility model increases the insulation performance of the terminal effectively and creepage size by using the umbrella structure on the insulation body, consequently the problems of small discharge clearance, short creepage distance, nonideal insulation strength and the like are solved for a device connection wire. The conductive bar can increase the sectional area of a conductor. The pressure plate can improve effective contact area and reduce contact resistance.
Description
Technical field
The utility model relates to a kind of binding post, particularly is applied to the bus binding post of the low voltage electrical equipment in Coal Mechanical field.
Background technology
In existing flame proof low voltage product, the low-voltage bus bar binding post of product is varied, but the problem that the ubiquity discharging gap is little, creepage distance is short, dielectric strength is not enough and conductive current is little.
Summary of the invention
Goal of the invention: the utility model is at above-mentioned technical problem, a kind of low-voltage bus bar binding post is provided, and it can effectively increase the insulation property of binding post, increases creepage size, increase conductive area, thereby solve discharging gap, creepage distance, the dielectric strength problem of interfacility link.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of low-voltage bus bar binding post, it comprises insulator, and busbar passes insulator; Be fixed with pressing plate on the busbar at insulator two ends, pressing plate is provided with the groove that cable is installed, and described insulator is a beveled structure.
Wherein, the cross section of described busbar is a rectangle.
Wherein, busbar and insulator are cast into one.
Wherein, the longitudinal center line of described busbar overlaps with the longitudinal center line of insulator.
Wherein, pressing plate is provided with plain cushion and bullet pad by being bolted on the busbar between nut and the busbar.
Beneficial effect: (1) makes it can effectively increase the insulation property of binding post by adopt beveled structure on insulator, increases creepage size, thus problems such as the discharging gap that solves interfacility link is little, creepage distance weak point, dielectric strength difference.(2) adopt busbar can increase the sectional area of electric conductor, can improve effective contact area, reduce contact resistance with pressing plate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of insulator of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
Shown in Fig. 1,2 and 3, a kind of low-voltage bus bar binding post of the present utility model comprises insulator 1, busbar 2, pressing plate 3, packing ring 4, bullet pad 5, nut 6 and bolt 7.
Busbar 2 passes insulator 1, and insulator 1 and busbar 2 are cast into one.The cross section of busbar 2 is a rectangle, has effectively increased the sectional area of electric conductor.The longitudinal center line of busbar 2 overlaps with the kernel of section line of insulator 1 so that guarantee insulating material be symmetrically distributed in busbar 2 around.
On the busbar 2 at insulator 1 two ends, be fixed with pressing plate 3, be fixed with two block pressur plates 3 on the busbar 2 of every end.Pressing plate 3 is fixed in the screw on the busbar 2 by packing ring 4, bullet pad 5, nut 6.Pressing plate 3 is provided with the groove adaptive with cable, and external line is installed in this groove.
During use, the cable that needs are connected is pressed in the groove of pressing plate 3, can jam-packed.
The utility model is applied in the BBD series flame-proof mine low-voltage variation case, is used for the external of connecting line, meets national standard, has reached purpose of design.
The above only is a preferred implementation of the present 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 improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
