Description

The electric energy meter electric source connecting box
Technical field
The utility model relates to a kind of electric energy meter electric source connecting box.
Background technology
In the prior art, the structure of electric energy meter electric source connecting box is directly with gib screw brace (as shown in Figure 1) to be fixed on the fixed electorde, brace and fixed electorde are to press and conductive structure, if outage wiring, normally by becoming flexible simultaneously, following gib screw, mobile brace, in order to prevent that brace from falling naturally and connect circuit under the effect of gravity, need a hand to mention brace at brace knuckle place with insulating tool, an other hand is tightened gib screw, wiring finishes, and unclamps gib screw again, allows brace drop naturally, tighten again, following gib screw, there are the following problems in the prior art: potential safety hazard is arranged, do not tighten if go up gib screw, drop the naturally danger of electric shock of brace; During wiring, move morely, influence work efficiency; Brace adds subpunch bed punching in man-hour, the back bending, and operation is more.
The utility model content
The utility model has proposed a kind of electric energy meter electric source connecting box in order to overcome above-mentioned deficiency, by architecture advances, improves performance.
The technical solution of the utility model is:
A kind of electric energy meter electric source connecting box comprises:
The insulation fixed mount, it is provided with some set of connections terminals, and this connection terminal comprises: go up fixed electorde; Be screwed into a plurality of gib screws of going up of fixed electorde; Following fixed electorde; Be screwed into down a plurality of inlet wire gib screws of fixed electorde; Brace which is provided with through hole and lower through-hole; Screwing, through hole is screwed into fixedly connected of fixed electorde in the insertion; Following screw inserts lower through-hole and is screwed into down fixedly connected of fixed electorde;
Be provided with insulation course between brace and last fixed electorde and the following fixed electorde, this insulation course is an one with the insulation fixed mount;
When screwing was unscrewed, screwing was electrically connected disconnection with brace, and perhaps, when screw was unscrewed instantly, following screw was electrically connected disconnection with brace.
Need to prove, the diameter of last through hole and lower through-hole necessarily greater than screwing, down screw diameter and leave surplus, select rational position can guarantee that brace does not contact with following screw with screwing, that is to say no power when unscrewing screwing and following screw.When screwing and following screw-driving, brace and last fixed electorde and following fixed electorde circuit communication.
Described insulation fixed mount is provided with the limited block that the restriction brace moves up and down.
The two ends up and down of described brace are circular arc, and described limited block comprises upper limit position block and lower position block, and upper limit position block and lower position block also are provided with and the corresponding circular arc of brace.
Described upper limit position block and lower position block and insulation fixed mount are one.
The last through hole of described brace and screwing concentric are provided with, lower through-hole and the also concentric setting of following screw, and the diameter of last through hole, lower through-hole is greater than the diameter 2-2.5mm of screwing, following screw.
Need to prove that screwing, down the diameter of screw is meant the diameter of threaded portion, screwing, the head diameter of screw is greater than the diameter of last through hole, lower through-hole down, so that screwing, down during screw-driving, guarantee and the brace electric connection.
It is safe and reliable to the utlity model has wiring, high efficiency, beneficial effect easy to use.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
Extremely shown in Figure 4 as Fig. 2, insulation fixed mount 2, it is provided with some set of connections terminals, and this connection terminal comprises: go up fixed electorde 110; Be screwed into a plurality of gib screws 11 of going up of fixed electorde 110; Following fixed electorde 120; Be screwed into down a plurality of gib screws 12 down of fixed electorde 120; Brace 4 which is provided with through hole and lower through-hole; Screwing 31, through hole is screwed into fixed electorde 110 fixedly connected 4 in the insertion; Following screw 32 inserts lower through-hole and is screwed into down fixed electorde 120 fixedly connected 4;
Be provided with insulation course 22 between brace 4 and last fixed electorde 110 and the following fixed electorde 120, this insulation course 22 is an one with insulation fixed mount 2;
When screwing 31 was unscrewed, screwing 31 was electrically connected disconnection with brace 4, and perhaps, when screw 32 was unscrewed instantly, following screw 32 was electrically connected disconnection with brace 4.
Insulation fixed mount 2 is provided with the limited block that restriction brace 4 moves up and down, particularly, the two ends up and down of brace 4 are circular arc, described limited block comprises upper limit position block 21 and lower position block 22, upper limit position block 21 and lower position block 22 also are provided with and brace 4 corresponding circular arcs, utilize circular arc to block brace 4 and make it can not move up and down.
Described upper limit position block 21 and lower position block 22 are one with insulation fixed mount 2.
