Detailed description of the invention
Watt metering distribution box as shown in Figure 1 to Figure 3, including watt metering distribution box originally
Body 1 and case lid 2, on the left and right sides wall of watt metering distribution box body 1, correspondence offers
Entrance hole 3 and wire hole 3, the inner bottom part being positioned at watt metering distribution box body 1 is provided with
Electric mounting board 4, on electric mounting board 4, the position of corresponding entrance hole 8 and wire hole 3 is divided
It is not fixedly installed junction block 5, electric mounting board 4 is further fixedly arranged on electronics watt-hour meter
Measuring device 6, is positioned on described case lid 2 and is provided with and the display end of electronics watt-hour meter measuring device 6
The through hole 7 socket-connected, the radiating end of electronics watt-hour meter measuring device 6 is fixed on electric mounting board 4
On.
Preferably, described watt metering distribution box body 1 and case lid 2 are the fire-retardant of insulation
Plastics, electric mounting board 4 is the metal material of heat conduction, and electric mounting board 4 is to pass through screw
With screw hole stake and the watt metering distribution being arranged on watt metering distribution box body 1 inner bottom part
Case body 1 is fixing to be connected.(the preferred aluminium sheet of metal material of heat conduction, due to electric degree
Metering switch box uses isolation material without having to worry about electric leakage electric shock)
Preferably, described watt metering distribution box body 1 is provided with thermal vias (heat radiation
Through hole symmetry is correspondingly arranged and contributes to forming convection current).
Preferably, described entrance hole 8 and wire hole 3 are all fixed with protective jacket 9 can do
Good protection wire is the most impaired.
Preferably, the inner side edgewise of described case lid 2 offers cannelure 10, described electricity
It is provided with, on the opening edgewise of degree metering switch box body 1, the annular protrusion coordinated with cannelure
11, described cannelure 10 is built-in with sealing ring, and case lid 2 is by screw and watt metering distribution
After the fixing connection of case body 1, described annular protrusion 11 compresses the sealing in cannelure 10
Circle.
