Abstract
The utility model is a combined type electric energy meter terminal comprising two or more the same or different basic modules and fixing in the electric energy meter body. The utility model is capable of making the three-phase meter and the simple-phase meter share the basic modules, thereby making the inventory more inflexible, and saving inventory cost, further more, the combined terminal has a smaller volume than that of the integral terminal knob case, saving the high cost materials of heat-proof and voltage endurance.
Description
Technical field
The utility model relates to the terminal of electric energy meter.
Background technology
Existing energy meter terminal adopts monoblock type terminal box more, terminal box is of a great variety, single-phase terminal box, three-phase terminal box, the terminal box of band auxiliary terminal, terminal box of charged pressure hook or the like are arranged, can not shared terminal box between the electric energy meter of different cultivars, thereby need are made and the terminal box of stock's many types, make that production and inventory cost are all bigger.And between the terminal box for same current specification, have a lot of general physical dimensions.
Summary of the invention
The purpose of this utility model is the problems referred to above of existing at traditional terminal box, provides a kind of terminal of the electric energy meter that makes different cultivars can shared a part of structure and can reduce the combined type electric energy meter terminal of the cost of energy meter terminal.
The purpose of this utility model is achieved in that the utility model combines to several basic modules identical or inequality by two, is installed in the electric energy meter housing.
Basic module in the utility model can be following structure: be provided with housing, and be provided with a pair of electric current outlet lambda line terminal and the screw that compresses terminals of a circuitry phase on housing.On the housing of aforementioned basic module, also have additional auxiliary terminal, then constitute the basic module of another kind of basic module----band auxiliary terminal.On the housing of aforementioned basic module, also have additional the voltage hook, then constitute the basic module of the charged pressure hook of another basic module----.
Basic module in the utility model also can be following structure: be provided with housing, and be provided with the electric energy measurement part of measuring a circuitry phase on housing.
Technique effect of the present utility model is:
1. but go out the energy meter terminal of multiple function by several basic module flexible combination;
2. realized that three-phase table and single-phase table can shared basic modules;
3. make the stock more flexible, save inventory cost;
4. multi-piece terminal is long-pending littler than monoblock type terminal box body, thereby has saved the expensive material of heat-resisting proof voltage;
5. because material reduces, can under the prerequisite that does not increase cost, adopt the thermoplastic that can be recycled of environmental protection to replace thermosetting terminal box material.
The utility model is described in further detail below in conjunction with drawings and Examples.
