The utility model discloses the spring compression type electric energy metrical termination of band control loop access, comprise ambroin shell, screw and brace, brace is fixedly connected with by two screws and is fixed on ambroin shell, ambroin shell is provided with wire jack and inserts the screw of screw, the position of screw and the position of wire jack suitable, it is characterized in that: described ambroin shell is also provided with control loop access terminal, the bottom in described screw chamber is provided with spring.The utility model structure is simple, with low cost, safe and reliable, easy to carry, to perform take the client controlled can Access Control loop safely and effectively, and also can make after loosened screw voltage, electric current, tripping operation line all the time with terminals close contact, greatly facilitate debugging and the replacing of acquisition terminal, effectively prevent the leakage meter of electric energy.

Description

With the spring compression type electric energy metrical termination of control loop access
Technical field
The utility model relates to a kind of improvement of electric energy metrical termination, specifically a kind of spring compression type electric energy metrical termination with control loop access, uses when connecting voltage, electric current and control loop when being applicable to electric energy meter and acquisition terminal installation.
Background technology
Along with the development of economy, user on annual new increases year by year, and major part installs and uses is box-type substation, the electric energy metering combined wiring box of current use, be made up of ambroin shell, screw and brace, brace is fixedly connected with by two screws and is fixed on ambroin shell, can On current or voltage by brace, ambroin shell is provided with wire jack and inserts the screw of screw, the position of screw and the position of wire jack suitable.Its weak point is: owing to all performing expense control to new upper client now, this just means needs the control loop by acquisition terminal to be connected with on-load switch, but control loop is with 220V voltage, for convenience of debugging safely or change acquisition terminal in charged situation, need control loop to access termination, the convenient break-make controlling trip(ping) circuit; Simultaneously the equipment such as transformer is in operational process, the slight vibrations of metering cabinet can be caused, thus loosening of electric energy metering combined wiring box screw can be caused, cause voltage, current return open loop state, make the few quantity calculation of electric energy meter, current return open circuit brings potential safety hazard also can to equipment and staff.
Summary of the invention
It is simple, with low cost, safe and reliable, easy to carry that the purpose of this utility model is to provide a kind of structure, energy safety control loop is accessed, utilize simultaneously its own resilient of spring leaf make voltage, electric current, control line all the time with terminals close contact, avoid the generation of open fault, the safe and stable operation of effective guarantee equipment and accurate-metering, prevent electric energy from leaking meter, guarantee the spring compression type electric energy metrical termination of the band control loop access of personal handling safety.
In order to reach above object, the technical scheme that the utility model adopts is: the spring compression type electric energy metrical termination of this band control loop access, comprise ambroin shell, screw and brace, brace is fixedly connected with by two screws and is fixed on ambroin shell, ambroin shell is provided with wire jack and inserts the screw of screw, the position of screw and the position of wire jack suitable, it is characterized in that: described ambroin shell is also provided with control loop access terminal, the bottom in described screw chamber is provided with spring.
The beneficial effects of the utility model are: structure is simple, with low cost, safe and reliable, easy to carry, to perform take the client controlled can Access Control loop safely and effectively, and after loosened screw, also can make voltage, electric current, tripping operation line all the time with terminals close contact, greatly facilitate debugging and the replacing of acquisition terminal, in on-load situation, safety is exchanged or field-checking electric energy meter, electric meter, the electrical equipments such as relay protection, effectively prevent the leakage meter of electric energy, stop the generation of electric energy metrical accident, guarantee personal handling safety, improve work on the spot efficiency.
Accompanying drawing explanation
Fig. 1 is structure schematic front view of the present utility model.
Fig. 2 is that the utility model analyses and observe enlarged diagram along the structure of Figure 1A-A.
In figure: 1, ambroin shell; 2, screw; 3, brace; 4, control loop access terminal; 5, spring; 6, wire jack.
Embodiment
The utility model is made with reference to Fig. 1, Fig. 2.The spring compression type electric energy metrical termination of this band control loop access, comprise ambroin shell 1, screw 2 and brace 3, brace 3 is fixedly connected with by two screws 2 and is fixed on ambroin shell 1, can On current or voltage by brace 3, ambroin shell 1 is provided with wire jack 6 and inserts the screw of screw 2, the position of screw 2 and the position of wire jack 6 suitable, this is prior art, it is characterized in that: described ambroin shell 1 is also provided with control loop access terminal 4, to facilitate Access Control loop, make it integrated, be convenient to the concentrated wiring management of terminal stud, bottom in described screw chamber is provided with spring 5.
Described control loop access terminal 4, the control loop wire with 220V voltage can be accessed, for performing the client of taking control, the control loop of acquisition terminal is needed to be connected with on-load switch, but control loop is with 220V voltage, by control loop access terminal 4, can conveniently debug safely in charged situation or change acquisition terminal, the convenient break-make controlling trip(ping) circuit.
When using the utility model, ambroin shell 1 is fixed in metering cabinet, screw 2 and brace 3 are all made up of the metal conducting electricity, the maximum diastole height of spring 5 is advisable with the central axis arriving wire jack 6, terminal is inserted in wire jack 6, and corresponding screw 2 is tightened, now, screw 2 heads on terminal holddown spring 5, like this when screw 2 loosens a little, spring 5 also can under natural resiliency effect diastole and make terminal continue contact with screw 2, ensure that screw 2, wire and spring 5 are in close contact state always, play the effect of correct metering, structure is simple, easy to use.
