Abstract
The utility model relates to a contact box comprising a box body as well as a coil-in cylinder and a coil-out cylinder integrally connected with the box body, wherein, outward scattering aprons is arranged on the outer peripheral walls of the box body, the coil-in cylinder and the coil-out cylinder, front connecting plates and rear connecting plates are arranged respectively in opposite directions at the two ends of supporting plates on the outer side of the box body and the coil-in cylinder, the distance between the end surface of the front connecting plate and the end surface of the coil-in cylinder is smaller than 20mm, and an inwards apron is arranged on the inner wall of one side where the opening of the coil-in cylinder is formed. By controlling the distance delta between the end surface of the front connecting plate of the supporting plate and the end surface of the coil-in cylinder below 20mm, the utility model reduces the length of the contact box and the size of a switch cabinet while retaining the electric property.
Description
Technical field
The utility model relates to a kind of contact box, belongs to the high-tension switch cabinet technical field.
Technical background
Be being connected between the primary cut-out of switch cubicle and high voltage bus row and high voltage bus cable to realize by patching of dynamic and static contact, therefore, contact in the switch cubicle becomes one of critical component of the normal operation of this type of switch cubicle, and contact box is as the insulation and the support of bus, and the quality of its quality will directly have influence on the insulation property of whole switch cubicle and the reliability of safe operation.For reaching security requirement, contact box is the size by the increase contact box usually, and the while is diffusing skirt outside the outside of box body increases again, increases the creepage distance of contact box.Therefore conventional contact box volume is bigger, makes the volume of switch cubicle also bigger.
Summary of the invention
The purpose of this utility model provides a kind of contact box, under the prerequisite that keeps electric property, can reduce the contact box volume.
The utility model is that the technical scheme that achieves the above object is: a kind of contact box, comprise box body and the wire feeding tube and the output cylinder that fuse with box body, has the outer skirt that looses on the periphery wall of box body and wire feeding tube and output cylinder, connecting plate and back connecting plate before the supporting bracket two ends in the box body and the wire feeding tube outside oppositely are provided with respectively, it is characterized in that: before described between end face and the wire feeding tube end face of connecting plate apart from δ between 15-20mm, and the inwall of wire feeding tube opening one side be provided with in diffusing skirt.
The utility model with supporting bracket before being controlled at below the 15-20mm between the end face of connecting plate and the wire feeding tube end face apart from δ, not only has the outer skirt that looses on the periphery wall of box body and wire feeding tube and output cylinder, and the skirt that looses in also being provided with on the inwall of wire feeding tube opening one side, therefore increased the creepage distance of contact box, make contact box reach electricity function index, satisfy the instructions for use of contact box, also shorten the contact box length dimension simultaneously, and reduce the volume of contact box, the size of dwindling switch cubicle.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model contact box.
Wherein: the 1-box body; The diffusing outward skirt of 2-; The 3-output cylinder; The 4-wire feeding tube; Diffusing skirt in the 5-, connecting plate before the 6-; Connecting plate behind the 7-.
Embodiment
See shown in Figure 1, contact box of the present utility model, comprise box body 1 and the wire feeding tube 4 and the output cylinder 3 that fuse with box body 1, box body 1, wire feeding tube 4 and output cylinder 3 can adopt nonconductive material to be integral, the contact fixture is arranged in the box body 1, busbar is fixed on the contact fixture by fixed contact, has the outer skirt 2 that looses on the periphery wall of box body 1 and wire feeding tube 4 and output cylinder 3, to increase creepage distance, connecting plate 6 and back connecting plate 7 before the supporting bracket two ends in the box body 1 and wire feeding tube 4 outsides oppositely are provided with respectively, be fixed with two threaded blocks on the preceding connecting plate 6, also be provided with threaded block on the back connecting plate 7, preceding connecting plate 6 and back connecting plate 7 are installed in respectively on separately the connector, between the end face of this preceding connecting plate 6 and wire feeding tube 4 end faces apart from δ less than 20mm, this can be less than 16mm, to reduce the length dimension of contact box apart from δ.See shown in Figure 1ly, the skirt 5 that looses in the inwall of wire feeding tube 4 openings one side is provided with to increase the creepage distance of contact box, makes contact box reach electric property.
