Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 8, a power distribution panel of a separable electric power meter box having a main switch box 11 and a meter box 12 equipped with a plurality of meters 20, which are separated from each other, wherein the main switch box 11 is equipped with a main switch connected to an external power transmission line, and the meter box 12 is fixedly equipped with a plurality of meters 20, each of which has one end communicating with the main switch and the other end normally communicating with a resident for measuring the power consumption of the resident.

In order to solve the problems of excessive wiring, confusion and influence on the later-stage quick overhaul operation caused by the fact that a plurality of meters are assembled in a single metering box 12 at present, as shown in fig. 2, a plurality of distribution boards 3 which are in pluggable connection with a single meter 20 are uniformly distributed in the metering box 12, and each distribution board 3 is communicated with the main switch box 11. Specifically, the wires extending into the metering box 12 by the main switch are laid by copper bars (which are shielded by baffles arranged in the metering box 12 and not shown in the figure), and the copper bars have the regularity of wiring and are not easy to bend, so that the wires are not in a chaotic state caused by poor mutual conditions compared with the conventional flexible wires. Each distribution board 3 is provided with a plug-in column connected with a corresponding copper bar, and the meter is communicated with the distribution board 3 and the main switch through the plug-in column, so that the assembly communication of the metering box and the distribution board 3 can be quickly separated. And then can be quick overhauld and assemble the counter, and when the needs overhauld the copper bar, can dismantle the baffle and carry out directly perceivedly (the copper bar wiring has regularity, compares its connected state of clear definition of flexible wire).

As shown in fig. 3, after the distribution board 3 is connected with the copper bar through the plugging posts, assembly holes 3a which are connected and fastened with the metering box 12 (inner bottom surface) are uniformly distributed on the board body of the distribution board 3, and preferably, the distribution board 3 and the metering box 12 (the inner bottom surface of the distribution board is prefabricated with threaded holes connected with the threaded rods) are assembled and fastened through penetrating threaded rods so as to hang and support the metering device 20. Since the back side of the switchboard 3 has copper bar wiring, a gap exists between the switchboard 3 and the inner bottom surface of the metering box 12, and when the switchboard 3 is fastened by the screw, the external force applied is too large, the switchboard 3 is extruded towards the inner bottom surface direction of the metering box 12, so that cracks or fissures (shown in a in fig. 3) appear on the surface of the switchboard 3 as shown in fig. 3, the switchboard 3 is damaged, replacement is needed, and the assembly cost is increased. In order to solve this problem, as shown in fig. 4 to 5, an auxiliary leveling frame 4 (preferably, a hard material bracket) is further attached to the outer surface of the power distribution board 3, and a hole 4a corresponding to each of the fitting holes 3a is formed in the auxiliary leveling frame 4. During assembly, the auxiliary leveling frame 4 is attached to the outer surface of the distribution board 3, the auxiliary leveling frame 4 and the distribution board 3 can be bonded preferably, then the screw rod penetrates through the perforation 4a and the assembly hole 3a, the screw rod is connected with the threaded hole on the inner bottom surface of the metering box 12, when the auxiliary leveling frame is fastened, the plurality of screw rods are guaranteed to have the same horizontal fastening surface through the hard structure of the auxiliary leveling frame 4, the problem that the crack appears after the surface of the distribution board is bent due to overlarge fastening force applied by a single screw rod is avoided, and therefore the integrity of the distribution board 3 is effectively protected.

Because the detachable plug-in connection of the meter is realized through the distribution board 3, the stability of the meter on the inner bottom surface of the metering box 12 is lower than that of the conventional meter, in order to improve the stability of the meter after being plugged in with the distribution board, as shown in fig. 6, a limiting board 5 capable of being pressed against the top end of the meter 20 is horizontally hinged on the top of the outer surface of the distribution board 3, and a torsion spring (not shown in the figure) for driving the limiting board 5 to be pressed against the top surface of the meter 20 is arranged at the hinge position of the limiting board 5. When the counter is assembled in a plugging manner, the acting force of the torsion spring is manually overcome, the limiting plate 5 is driven to rotate upwards and parallel to the surface of the distribution board 3, in this state, smooth plugging of the counter and the plugging column of the distribution board can be realized, after the plugging is completed, the external force applied to the limiting plate 5 is withdrawn, under the acting force of the torsion spring, the limiting plate 5 is pressed on the top surface of the counter, the counter is pressed towards the bottom of the plugging column of the distribution board, and therefore the stability of the plugged counter and the stability of circuit conduction are improved.

Further to enhance the stability after plugging the gauge, as shown in fig. 7-8, an anti-drop plate 51 attached to the top of the outer surface of the gauge 20 is extended downward at the outer end of the limiting plate 5. After the limiting plate 5 is pressed against the top surface of the gauge 20 by the driving of the torsion spring, the anti-falling plate 51 of the limiting plate 5 is attached to the top of the outer surface of the gauge 20, so that the state of the gauge after being inserted is further limited, and the stability of the gauge after being inserted is improved.

The principle of the application is as follows: through set up a plurality of distribution boards of pegging graft with the counter in the batch meter, with the counter through the quick pegging graft of pegging graft mode and the distribution board of pegging graft and be connected, solve at present and be connected the wire confusion that exists through wire and counter, be difficult to with the quick dismantlement of counter when overhauing, and lead to the fact the difficult problem to overhaul work. After the counter is arranged in a pluggable connection mode, the stability of the counter after plugging and the stability of circuit conduction can be guaranteed through the limiting plate hinged to the top of the distribution board.

The foregoing has outlined and described the basic principles, main features and advantages of the present application. Various changes and modifications may be made to the present application without departing from the spirit and scope of the application, and such changes and modifications fall within the scope of the application as hereinafter claimed.
