Technical Field

[0001] The utility model relates to the technical field of electric energy meter wiring, in particular to a single-phase electric energy meter wiring structure. Background Technique

[0002] Single-phase electric energy meters are used for active electric energy measurement: accurate measurement, modular and small volume (18mm), can be easily installed in various terminal distribution boxes, rail-mounted, bottom-wired, perfectly matched with miniature circuit breakers, intuitive and easy-to-read mechanical display, reducing the risk of data loss due to accidental power outages, without external working power supply, and wide working temperature range.

[0003] When wiring a single-phase electric energy meter, it is usually necessary for electric power construction personnel to insert wires into the corresponding wiring terminals in sequence and then tighten the bolts to clamp them. However, the wiring terminals of the single-phase electric energy meter are located at the bottom, and it is necessary to look up for a long time during wiring. When tightening the screws, it is necessary to hold the wire with one hand and tighten the screws with the other hand, which is very inconvenient.

[0004] Therefore, a single-phase electric energy meter wiring structure is proposed to solve the above problems. Content of the Utility Model

When tightening the screws, it is necessary to hold the wire with one hand and tighten the screws with the other hand, which is very inconvenient.

[0007] 2. Technical Solutions

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] A single-phase electric energy meter wiring structure includes an electric energy meter. A wiring cover is clamped inside the bottom of the electric energy meter. A plurality of inlet coils are equidistantly installed at the bottom of the wiring cover. A plurality of positioning cylinders are fixedly installed at equal intervals on the top of the wiring cover. One end of the positioning cylinder coincides with the edge of the wiring terminal inlet of the electric energy meter. A plurality of groups of partition plates are equidistantly installed inside the wiring cover. Two partition plates form a group. A fixed sleeve is fixedly installed at the bottom inside the partition plate. A clamping sleeve is slidably installed at the top inside the partition plate. The two ends of the fixed sleeve coincide with the bottom edge of the inner side of the inlet coil and the bottom edge of one end of the positioning cylinder respectively.

[0010] As a preferred solution of the present utility model, a mounting plate is fixedly installed on the back of the electric energy meter. Through holes for bolt inlet installation and fixation are opened at the four corners of the outer side of the mounting plate.

[0011] As a preferred solution of the present utility model, a slot matching the size of the wiring cover is opened at the bottom of the electric energy meter, and clamping grooves are symmetrically opened at the bottom of both side surfaces of the electric energy meter.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Embodiment:

[0025] Please refer to Figures 1-4 , this embodiment provides a single-phase electric energy meter wiring structure, including an electric energy meter 2. A wiring cover 3 is clamped inside the bottom of the electric energy meter 2. A plurality of incoming coils 7 are equidistantly installed at the bottom of the wiring cover 3. A plurality of positioning cylinders 4 are fixedly installed at equal intervals on the top of the wiring cover 3. One end of the positioning cylinder 4 coincides with the edge of the wiring terminal inlet of the electric energy meter 2. A plurality of groups of partitions 8 are equidistantly installed inside the wiring cover 3. Two partitions 8 form a group. A fixing sleeve 10 is fixedly installed at the bottom inside of the partition 8. A jacket 9 is slidably installed at the top inside of the partition 8. The edges at both ends of the fixing sleeve 10 coincide with the bottom edge of the inner side of the incoming coil 7 and the bottom edge of one end of the positioning cylinder 4 respectively. When performing the wiring operation of the electric energy meter 2, first, the zero wire and the live wire are distributed and inserted into the incoming coil 7 according to the position distribution, pass through the inside of the fixing sleeve 10, and pass out from the inside of the positioning cylinder 4, and then cut to the corresponding length. At this time, the whole wiring cover 3 is inserted into the bottom of the electric energy meter 2 to complete the wiring, without the need to connect the wires one by one with the head up, let alone hold the wire with one hand and tighten the screw with the other hand, thus effectively reducing the operation difficulty of the power personnel and improving the convenience of wiring the electric energy meter 2.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a slot matching the size of the wiring cover 3 is opened at the bottom of the electric energy meter 2, and card slots 201 are symmetrically opened at the bottom of both sides of the electric energy meter 2. Buckles 6 are symmetrically installed on both sides of the wiring cover 3. The buckle 6 is inclined outward at an angle of 30 degrees in the initial state. One end of the buckle 6 matches the size of the card slot 201. When the wiring cover 3 is inserted into the slot, the buckle 6 is squeezed. When the buckle 6 passes through the card slot 201, one end of it pops out from the inside of the card slot 201, thereby clamping the wiring cover 3 in the slot at the bottom of the electric energy meter 2.

[0027] In this embodiment, asFigure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , a plurality of circular hole grooves 301 are equidistantly arranged on one side surface of the wiring cover 3. Bolts 5 are installed inside the circular hole grooves 301, and the bolts 5 are threadedly connected to the inner side surfaces of the circular hole grooves 301. After the bolts 5 are tightened clockwise, they can extend to the inside of a group of partition plates 8 to squeeze the incoming line of the clamping sleeve 9. When the length of the wire is cut at the top of the positioning cylinder 4, the bolts 5 are tightened. At this time, one end of the bolts 5 squeezes the clamping sleeve 9 to move towards the fixed sleeve 10, so that the clamping sleeve 9 and the fixed sleeve 10 clamp the wire outer skin incoming line, thereby fixing the wire incoming line and preventing it from slipping.

[0028] Working principle: When the single-phase watt-hour meter wiring structure is in use, first, the neutral wire and the live wire are distributed according to the positions and inserted into the incoming coil 7, pass through the inside of the fixed sleeve 10, and pass out from the inside of the positioning cylinder 4, and then cut to the corresponding length. Then the bolts 5 are tightened. At this time, one end of the bolts 5 squeezes the clamping sleeve 9 to move towards the fixed sleeve 10, so that the clamping sleeve 9 and the fixed sleeve 10 clamp the wire outer skin incoming line, thereby fixing the wire incoming line and preventing it from slipping. At this time, the whole wiring cover 3 is inserted into the bottom of the watt-hour meter 2. At this time, the buckle 6 is squeezed. When the buckle 6 passes through the card slot 201, one end of it pops out from the inside of the card slot 201, so that the wiring cover 3 can be clamped in the slot at the bottom of the watt-hour meter 2 to complete the wiring. There is no need to carry out the wiring operation of looking up one by one, and there is no need to hold the wire with one hand and tighten the screw with the other hand, thus effectively reducing the operation difficulty of the power personnel and improving the convenience of wiring the watt-hour meter 2.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
