The utility model purpose of design is for avoiding the disadvantages of background technology part, with existing connection box of electric energy meter terminal, be designed to the cup joint style mode of connection and cup joint style ramp (seeing accompanying drawing 1), this mode of connection and ramp both can avoid the traditional formula that presses closer ramp (accompanying drawing 3) when using multiply aluminium matter lead as the electric energy meter outside lead effectively, used the unsafe factor that brings owing to press closer formula wiring easy damaged lead to electric energy meter; Can solve its pressing plate of traditional presser type ramp (seeing accompanying drawing 4) the use inconvenience that can not upspring automatically and the defective that is difficult for compressing again.
Design of the present utility model: design of the present utility model is a purpose with damage wires not, and employing activity anchor ear is as the main body of ramp, and therefore contact resistance is little because its contact area is big, thereby has reduced the contact heating of lead effectively.Technical scheme: a kind of connection box of electric energy meter terminal, by brace (3), movable anchor ear (2), trip bolt (1) and insulation shell (4) have been formed scalable wiring hole size ramp, movable anchor ear (2) is positioned at insulation shell (4), insulation shell has entrance hole on (4), the hoop chamber of movable anchor ear (2) is directly to entrance hole, trip bolt (1) is screwed on the movable anchor ear (2), brace (3) is fixed on the insulation shell (4), the end of trip bolt (1) contacts with brace (3), and movable anchor ear (2) dwindles wiring hole with tightening of trip bolt (1) and compresses lead, with trip bolt (1) loosen and the convenient lead of removing.
The comparison of the connection box of electric energy meter terminal of the utility model and prior art, it is big to have the wiring aperture, advantages such as wiring is easy to operate, no matter single cord and stranded conductor all are easy to use, the wiring of particularly suitable multiply aluminium matter lead, contact reliably and to lead does not have any damage after the wiring, can prevent and solve defective effectively because of the architectural feature of the mode of connection of traditional electric energy meter and ramp, to stranded conductor aluminium matter stranded conductor easy damaged particularly, the connection box of electric energy meter place easily takes place cause many unsafe factors of local pyrexia and the defective of using inconvenience because of loose contact.
Description of drawings:

Fig. 2 is the stereogram of the utility model ramp
Fig. 3 is the cutaway view of the traditional formula that presses closer ramp.
Fig. 4 is the cutaway view of traditional presser type ramp.
In conjunction with the accompanying drawings 1 and the real row of the 2 pairs of the utility model of accompanying drawing be further described below.
Formed scalable wiring hole size ramp by brace (3), movable anchor ear (2), trip bolt (1) and insulation shell (4), movable anchor ear (2) can be with the tightening and loosen to produce and move of trip bolt, and wiring hole is dwindled and reduces; Movable anchor ear (2) is positioned at housing, has entrance hole on the housing, and the hoop chamber of movable anchor ear is directly to entrance hole; Trip bolt (1) is screwed on the movable anchor ear (2); The end of trip bolt contacts with brace, brace be fixedly mounted in the housing of insulating material immovable.Movable anchor ear (2) dwindles wiring hole to compress lead, loosening and break away from lead with trip bolt (1) with tightening of trip bolt (1).Movable anchor ear (2) is the metal material manufacturing, has two screws on it and is complementary with trip bolt (1) simultaneously.The end diameter of trip bolt (1) is criticized the diameter of pilot hole greater than the spiral shell of insulating material.The position that brace (3) and movable anchor ear (2) are complementary is shaped on the rib of indention.When trip bolt (1) when clockwise rotating movable anchor ear move to screw orientation, wiring hole dwindles; When trip bolt was tightened clockwise, wiring hole was reduced to minimum, this moment with outside lead with compressed securely in flakes, realized connection box of electric energy meter.Go up the rib that indention has been designed at the position that contacts with lead at movable anchor ear (2) with brace (3), increased the frictional force of wiring hole wall, make wiring more reliable lead.When trip bolt (1) when rotating counterclockwise, because being positioned at the spiral shell of being made by insulating material of screw head, to criticize the diameter of pilot hole littler than the diameter of screw head, screw can not move axially and make movable anchor ear to oppositely moving wiring hole be amplified, thereby loosens the convenient dismounting that wiring has realized connection box of electric energy meter.Even do not having under the situation of wiring, the size of wiring hole can be with trip bolt 1) turn size freely.Because movable anchor ear dwindles the relative motion of not having other direction in the process at wiring hole, so electric energy meter outside lead lead in compacted process is to be subjected to unexpected damage, therefore the quality of wiring is especially for the wiring of the lead of multiply aluminium matter, make the line conduction quality good, the contact resistance of wiring place is little, and power loss is little during big electric current.Exempted the mode of connection of traditional electric energy meter product and ramp thereof the potential safety hazard when adopting the wiring of aluminium matter stranded conductor under the especially big current conditions of stranded conductor.
