Description
Technical field
The present invention relates to a kind of electric energy meter electric source connecting box.
Background technology
in 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 fixed electorde, brace and fixed electorde are to press and conductive structure, if outage wiring, normally by becoming flexible simultaneously, lower gib screw, the mobile link sheet, in order to prevent that brace from naturally falling and connecting circuit under action of gravitation, need a hand to mention brace with insulating tool at brace knuckle place, an other hand is tightened gib screw, wiring is complete, unclamp again gib screw, allow brace naturally drop, tighten again, lower gib screw, in prior art, there are the following problems: potential safety hazard is arranged, if upper gib screw is not tightened, naturally the drop danger of electric shock of brace, during wiring, move morely, affect work efficiency, brace adds subpunch bed punching in man-hour, rear bending, and operation is more.
Summary of the invention
The present invention has proposed a kind of electric energy meter electric source connecting box in order to overcome above-mentioned deficiency, by architecture advances, improves performance.
Technical scheme of the present invention is:
A kind of electric energy meter electric source connecting box comprises:
The insulation fixed mount, it is provided with some winding line terminals, and this connection terminal comprises: upper fixed electorde; Be screwed into a plurality of upper gib screw of fixed electorde; Lower fixed electorde; Be screwed into a plurality of inlet wire gib screws of lower fixed electorde; Brace which is provided with through hole and lower through-hole; Screwing, in insertion, through hole is screwed into fixed electorde and is fixedly connected with sheet; Lower screw, the insertion lower through-hole is screwed into lower fixed electorde and is fixedly connected with sheet;
Be provided with insulation course between brace and upper fixed electorde and lower fixed electorde, this insulation course is integrated with the insulation fixed mount;
When screwing was unscrewed, screwing was electrically connected to disconnection with brace, and perhaps, when screw was unscrewed instantly, lower screw was electrically connected to disconnection with brace.
Need to prove, the diameter of upper through hole and lower through-hole is necessarily greater than the diameter of screwing, lower screw and leave surplus, select rational position can guarantee when unscrewing screwing and lower screw, brace does not contact with lower screw with screwing, that is to say no power.When screwing and lower screw-driving, brace and upper fixed electorde and lower 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 also is provided with the circular arc corresponding with brace with lower position block.
Described upper limit position block and lower position block and insulation fixed mount are integrated.
The upper through hole of described brace and screwing concentric arrange, lower through-hole and the also concentric setting of lower screw, and the diameter of upper through hole, lower through-hole is greater than the diameter 2-2.5mm of screwing, lower screw.
Need to prove, the diameter of screwing, lower screw refers to the diameter of threaded portion, and the head diameter of screwing, lower screw is greater than the diameter of upper through hole, lower through-hole, so that when screwing, lower screw-driving, guarantee and the brace electric connection.
It is safe and reliable that the present invention has wiring, high efficiency, beneficial effect easy to use.

Fig. 2 is one-piece construction schematic diagram of the present invention.
Fig. 3 is the side cutaway view of Fig. 2.
Fig. 4 is the side cutaway view of insulation fixed mount in Fig. 2.
Embodiment
Now the present invention is further illustrated by reference to the accompanying drawings:
As extremely shown in Figure 4 in Fig. 2, insulation fixed mount 2, it is provided with some winding line terminals, and this connection terminal comprises: upper fixed electorde 110; Be screwed into a plurality of upper gib screw 11 of fixed electorde 110; Lower fixed electorde 120; Be screwed into a plurality of lower gib screw 12 of lower fixed electorde 120; Brace 4 which is provided with through hole and lower through-hole; Screwing 31, in insertion, through hole is screwed into fixed electorde 110 and is fixedly connected with sheet 4; Lower screw 32, the insertion lower through-hole is screwed into lower fixed electorde 120 and is fixedly connected with sheet 4;
Be provided with insulation course 22 between brace 4 and upper fixed electorde 110 and lower fixed electorde 120, this insulation course 22 is integrated with insulation fixed mount 2;
When screwing 31 was unscrewed, screwing 31 was electrically connected to disconnection with brace 4, and perhaps, when screw 32 was unscrewed instantly, lower screw 32 was electrically connected to 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 the circular arc corresponding with brace 4, 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 integrated with insulation fixed mount 2.
The upper through hole of brace 4 and screwing 31 concentric settings, lower through-hole and the also concentric setting of lower screw 32, the diameter of upper through hole, lower through-hole is greater than the diameter 2-2.5mm of screwing 31, lower screw 32, the monolateral gap that has more than 1mm, when guaranteeing that screwing 31 or lower screw 32 are unscrewed, upper fixed electorde 110 and 120 outages of lower fixed electorde.
during use, as long as with screwing 31, any one in lower screw 32 unscrewed, upper fixed electorde 110 and lower fixed electorde 120 outages, tighten again after completing wiring, obviously, compared with prior art, need not loosening two screws and mobile link sheet, need not two hands operates simultaneously, solved the operating safety under the energising situation, also improved simultaneously work efficiency, in addition, the shape of brace 4 is simpler than the brace of prior art, the insulation course 22 that newly increases, upper limit position block 21 and lower position block 22 and 2 one-shot formings of insulation fixed mount, easy to process, the present invention has safety, characteristics conveniently.
