Abstract
The utility model relates to an I type mother board joint protection box. The target is to provide a protection box which has the characteristics of better dust tightness, waterproofness, high temperature resistance, insulating performance, and anti-leakage performance between cover plates. The technical scheme is that the I type mother board joint protection box includes a rectangular hollow box which is formed by superposing an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate can be opened and closed; a rear side is connected into one body; and left and right sides are provided with an opening which enables a mother board to pass through; and front sides of the upper and lower cover plates are provided with folding edges which can superpose to each other and are fixed by inserting fasteners. The I type mother board joint protection box is characterized in that an edge of one folding edge is provided with a flanging which extends to the other folding edge, and the flanging just faces to and resists a gap which is formed by superposing the folding edge of the lower cover plate and the folding edge of the upper cover plate. The opening matches with the cross section of the mother board. The extending height of the flanging matches with the thickness of the folding edge. The two folding edges are provided with a plurality of corresponding circular holes which enable the fasteners to insert into, and the fasteners are locking screws.
Description
Technical field
The utility model relates to protection box, is specifically related to a kind of I type busbar joint protection box.
Background technology
Busbar be meant the switch in the total system switch and each shunt circuit in the mains supply line in the distribution electric supply installation (copper bar, aluminium row are busbar), in the switch cubicle be connected copper bar or aluminium is arranged, insulation processing is carried out on the surface, uses mainly as lead.Owing to busbar in the middle of use easily because exposed joint produce variety of problems (as: wet sudden strain of a muscle, pollution flashover, salt fog chemical gas burn into artificially contact, toy or foreign material are made contact, power stealing etc.) and then cause power failure that short circuit or ground connection causes, damage accidents such as power equipment and electric shock, therefore existing busbar joint all adopts busbar joint protection box to protect.The insulating protection of the busbar of power products such as high-low pressure transformer station and high and low voltage switch cabinet had fire-retardant, high voltage bearing characteristics during busbar joint protection box was applied to usually, was divided into two types of 10KV, 35KV; Not enough below but existing busbar joint protection box exists: the one, the faying face between the adjacent cover plate has narrow and small slit; When busbar surrounding environment humidity makes slit place have moisture content or surrounding environment impurity more for a long time; Moisture content or airborne impurity are easy to get in the protection box, influence power supply safety; The 2nd, because busbar inserts high-tension electricity, can discharge in the busbar tip, and can leak electricity in the place, slit between the adjacent cover plate, have potential safety hazard.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, a kind of I type busbar joint protection box is provided, the characteristics that this protection box should have better dustproof and waterproof property, heat-resisting quantity, insulating properties and prevent to leak electricity between the protection box cover plate.
For realizing above purpose, the technical scheme below the utility model has adopted:
A kind of I type busbar joint protection box; Comprise by upper cover plate and lower cover and being built up opening or closing and trailing flank is connected as a single entity and left and right sides face is shaped on the rectangle hollow box body that can supply the opening that busbar passes through respectively; The leading flank of said up and down two cover plates is shaped on respectively and can be superimposed with each other and interts fixing flanging with securing member; It is characterized in that: the edge of one of them flanging is shaped on the flange that stretches toward another flanging direction, this flange over against and stopping the flanging of flanging and upper cover plate of the lower cover gap after superimposed.
The cross section fit of said opening and busbar.
The height that said flange stretches and the thickness fit of said flanging.
Said two flangings respectively are shaped on the circular hole that several are used to insert securing member accordingly.
Said securing member is a stopping screw.
This protection box adopts silastic material to make.
The beneficial effect of the utility model is: because the edge of one of them flanging of cover plate is shaped on the flange that stretches toward another flanging direction up and down; This flange over against and be blocked between lower cover and the upper cover plate; The height that flange stretches and the thickness fit of said flanging; Therefore can stop two flangings of cover plate up and down gap after superimposed, thereby stop the electric discharge phenomena between the protection box cover plate, prevent short circuit or earth fault that toy, artificial contact cause; Improve fail safe, and made protection box have better water proof and dust proof property.In addition, because this protection box adopts the high quality silicon elastomeric material to make, so insulation property further strengthen, also significantly improve useful life.

Embodiment
Below in conjunction with Figure of description, the utility model is described further.
As shown in the figure; A kind of I type busbar joint protection box; This I type busbar joint protection box comprises the rectangle hollow box body that is built up opening or closing by upper cover plate 1 and lower cover 2; This rectangular box trailing flank is connected as a single entity (being that an end of upper cover plate and an end of lower cover are connected as a single entity), and the left and right sides face of this rectangle hollow box body is shaped on the opening 5 (the cross section fit of this opening and busbar) that can supply busbar to pass through.
The front side of said upper cover plate is shaped on a flanging 6, and the front side of lower cover also is shaped on a flanging 6, and described two flangings can fold each other and two flangings respectively are shaped on the circular hole 3 that several are used to insert securing member accordingly, and superimposed back is interted fixing with securing member.Owing to have certain interval after two flangings are superimposed; So the edge of one of them flanging is shaped on the flange 4 that stretches toward another flanging direction; This flange over against and stopping the gap between two flangings of lower cover and upper cover plate; The height that flange stretches and the thickness fit of said flanging, therefore can block electric spark directly from about discrepancy path the gap of two flangings of cover plate, thereby effectively stop the discharge electrical phenomena between the protection box cover plate; Improve security performance, and made protection box have better water proof and dust proof property.
The utility model adopts the high quality silicon elastomeric material to be made, and has than existing better insulating properties of busbar joint protection box and heat-resisting quantity.Before the utility model assembling is that deployed condition is (as shown in Figure 4; Directly injection moulding is processed), turn down after being enclosed within on the busbar joint during use superimposedly again, adopt stopping screw (plastics stopping screw, directly outsourcing) to insert the circular hole 3 on two flangings at superimposed place at last, thereby flanging is fixed.
The utility model can be according to the specification of busbar, the series of products that sized goes out different size.
