However, the current installation of electric energy meters is the traditional wiring method, which basically uses copper wires to be repeatedly laid out in the box. When the device is fastened, it is locked with screws, and the contact surface of the wires at the connection is only about 30%, which is prone to current obstruction and causes the wire connection to be heated and burned; this traditional installation method of electric energy meters not only consumes a lot of metal materials, Moreover, the installation is labor-intensive and time-consuming, the work efficiency is low, and the labor cost is huge; and the installation position of the meter box is demanding and occupies a large area

Embodiment Construction
[0017] The conductive rail-type integrated electric meter box consists of a box body 1, a conductive rail placement slot 2, a conductive rail 3, a connecting piece 4, an electric energy meter plug-in device 5, a power connection device 6, an insulating partition 7, a sliding type electric energy meter 12 and The branch switch 17 is composed. The box 1 is provided with a conductive rail placement slot 2. The function of the conductive rail placement slot 2 is to provide a fixed space for the conductive rail 3. The number of the conductive rail placement slot 2 is determined according to the actual situation, generally 4, 3 live wire slots , 1 zero wire slot; the shape of the slot is determined according to the shape of the conductive rail. The cross-sectional shape of the conductive rail placement slot 2 can be flat, square or round according to the cross-sectional shape of the conductive rail 3. The conductive rail placement slot 2 A conductive rail 3 is placed inside, and a po...

The invention relates to a meter box supplying power for an electric energy meter through a conductor rail and belongs to the technical field of low-voltage power distribution and electric energy metering devices. The integrated meter box comprises a box body, the conductor rail, an insulation partition, a sliding type electric energy meter and the like. The box body is provided with a conductor rail holding groove for holding the conductor rail. An electric energy meter socketing device is made on the conductor rail. The insulation partition covers the conductor rail holding groove and is provided with an electric energy meter sliding-clamping hole, an electric energy meter inserting-sliding contact hole, a signal contact and a signal bus, and the sliding electric energy meter and a branch switch are mounted on the insulation partition. A conventional wiring mode of the meter box is changed into a mounting mode of inserting-sliding or socketing of the conductor rail, wiring is standardized, contact area of the electric connecting point is larger and can reach 70%, complicated and repeating manual wiring is substituted by assembly lines in workshops, comprehensive cost of production and construction of the meter box is greatly reduced, and the electric energy metering devices can be mounted more standardly and conveniently.
Description
technical field [0001] The invention relates to a conductive rail type integrated electric meter box, which belongs to the technical field of low-voltage power distribution and electric energy metering devices. Background technique [0002] The construction of smart grid is closely related to the requirements of low-carbon, environmental protection, technology, green and harmonious development of human society. Material saving is an important indicator in the construction of smart grid. In addition to ensuring safety, simple construction, convenient operation, and saving labor, on the other hand, it is necessary to save raw materials in product production and use to the greatest extent. However, the current installation of electric energy meters is the traditional wiring method, which basically uses copper wires to be repeatedly laid out in the box. When the device is fastened, it is locked with screws, and the contact surface of the wires at the connection is only about 30...
