In the utility model, six insulation boards are followed successively by base plate, cover plate, a pair of long side plate and a pair of short side plate; Base plate is placed with the bar shaped notch parallel with arris with cover plate along the arris direction; Arris arranges plate up and down in the short side plate, vertical bar shaped notch is offered near edge position in the left and right sides; Be provided with plate on all arris of long side plate, offer vertical bar shaped notch and incoming line on its plate body; In the bar shaped notch on the last lower plugboard of long side plate and short side plate corresponding insertion base plate and the cover plate, the plate of the long side plate left and right sides inserts in the bar shaped notch of adjacent short side plate.
In the utility model, also comprise dividing plate, dividing plate upper edge and left and right sides arris are provided with plate, and dividing plate left and right sides plate is inserted in the vertical bar shaped notch on the long side plate plate face; Plate on long side plate, short side plate and the dividing plate all is inserted in the bar shaped notch of corresponding position on base plate and the cover plate.
In the utility model, the quantity of base plate is two, and two base plates are fitted fixing.
In the utility model, all offer pin hole on the plate of arris about long side plate and the short side plate.
Compared with prior art, the beneficial effects of the utility model are:
1. ohmically charged position is closed, and has significantly shortened electric clearance, can save installing space.
2. this pieced Rapid Combination mounting means need not the tapping of punching, and has reduced the set-up time.
3. can strengthen the assembly unit fastness at the plate place with pin is stuck, improve production efficiency, reduce cost.
