A kind of two modulus single-phase guide rail type electrical energy meters
The utility model relates to a kind of electric energy meter, especially relates to a kind of two modulus single-phase guide rail type electrical energy meters.
The mounting means that has more general single-phase electric energy meter at present now is wall-hanging or regulator cubicle is installed, and need be equipped with special watt-hour meter box during installation, and (small product size is relatively little greatly volume, function is few), inconvenience is installed in on-the-spot installation inconvenience, and its product inner structure complexity.If the mode that adopts screw to install is fixed on electric energy meter on the device such as electrical control cubicles, to waste time and energy, and need reserve screw at the place, fixed position, perhaps pre-sunk screw can't be regulated electric energy meter according to actual conditions after causing installing electric energy meter.Existing installation method can't satisfy the electric energy metrical demand of growing household electrical appliance and equipment.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of volume is little, reliability is high, conveniently install, two modulus single-phase guide rail type electrical energy meters of highly versatile.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of two modulus single-phase guide rail type electrical energy meters, comprise base, terminal base, wiring board, inserted sheet, shell and cover, described terminal base and wiring board are located in the cavity that is surrounded by base and shell, described terminal base is connected with wiring board by inserted sheet, and described cover is connected with shell, and this electric energy meter adopts the modularization design, described terminal base is modular construction, and removably connect with base, the width of described base is two moduluses, and the back side of base is provided with guide-track groove and elastic fastening hook.
Described cover is transparent cover.
Described base bottom is connected with slide.
Be connected with binding post on the described terminal base.
Described outer casing underpart is connected with terminal base by screw, and the bottom is provided with and renovates.
Compared with prior art, the utlity model has following advantage:
1, the utility model adopts the modularization design of similar miniature circuit breaker, the convenient installation, and suitable application area is wide, highly versatile, standard is strong;
2, the utility model can directly be fit in the terminal distribution box, adopt the guide tracked mounting means of 35mm standard, can realize that with equipment, room, zone be the electric energy metrical of least unit, volume is little, flexible for installation, avoided complicated construction links such as cabinet face perforate;
3, the output of the utility model connection terminal and isolating switch coupling can help and the isolating switch high speed interconnect;
4, separate type terminal base structural design: make shell mechanism have more versatility when ensureing the internal security spacing.

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.Present embodiment is that prerequisite is implemented with technical solutions of the utility model, provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Fig. 1-shown in Figure 5, a kind of two modulus single-phase guide rail type electrical energy meters, comprise base 1, terminal base 2, wiring board, inserted sheet 8, shell 3 and cover 4, terminal base 2 and wiring board are located in the cavity that is surrounded by base 1 and shell 3, and terminal base 2 is connected with wiring board by inserted sheet 8, cover 4 is connected with shell 3, this electric energy meter adopts the modularization design, and terminal base 2 is modular construction, and removably connects with base 1, outside the safe distance that guarantees between the current terminal, also taken into account its versatility like this.The width of base 1 is that (1 modulus is 18 ± 0.5mm) to two moduluses, the back side of base 1 is provided with guide-track groove 5 and elastic fastening hook, this electric energy meter can be installed on the 2.35mm standard guide rail by guide-track groove 5 and elastic fastening hook, has avoided complicated construction links such as cabinet face perforate, makes flexible for installation or the transformation convenience.Base 1 bottom is connected with slide 6.
Cover 4 is transparent cover, is the transparent material that stiffened is handled, and realizes not influencing the user scene and checks requirements such as electric energy meter, wear-resisting, high-protection level.
Be connected with binding post 7 on the terminal base 2.Shell 3 bottoms are connected with terminal base 2 by screw, and the bottom is provided with and renovates 9.Wiring board comprises upper plate 10, middle plate 11 and the lower plate 12 that connects successively.
The utility model adopts advanced chip technology and SMT technological design, and LCD shows to have pulse output and RS485 communication interface, the management of power use that has great convenience for the user; Having volume, little (2 moduluses, 1 modulus are 18 ± 0.5mm), low in energy consumption, the reliability advantages of higher.
