Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an auxiliary device for wiring and positioning of electricity meters. Background Technology

[0002] As the core equipment for electricity metering, the accuracy of the installation and wiring of electricity meters directly affects the fairness and impartiality of electricity metering and the safe and stable operation of the power grid. In low-voltage distribution networks, three-phase four-wire electricity meters are widely used. Their terminals usually need to connect three live wires (A, B, and C) and one neutral wire. In actual installation or maintenance, especially in situations where the space inside the distribution box is small and there are many wires, electricians need to accurately and orderly connect four thick-section wires from different directions to the corresponding terminals of the electricity meter.

[0003] This work relies entirely on the electrician's personal skills and experience. Electricians usually first perform a preliminary wire sequence and then connect the wires one by one. During the wiring process, the wires are prone to displacement and tangling due to their own weight or handling, leading to a chaotic wire sequence and making it very easy to make mistakes such as incorrect phase sequence or reversed live and neutral wires. Although there are some general cable positioning or binding tools on the market, there is a lack of auxiliary devices specifically designed for multi-wire wiring of electricity meters. Existing tools cannot effectively pre-position, isolate, and mark multiple wires before wiring, and cannot fundamentally avoid the chaos during the wiring process. Therefore, an auxiliary device for positioning wiring of electricity meters is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for wiring and positioning of electricity meters to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for wiring and positioning of an electricity meter, comprising a device body, a sliding groove inside the device body, multiple limiting rods installed in the sliding groove, multiple wiring blocks slidably installed in the sliding groove, an indicator light installed at one end of each wiring block, a wire-passing groove inside the wiring block, a communicating inner cavity at one end of the wire-passing groove, a spring installed in the inner cavity, a clamping block installed at one end of the inner cavity, and an arc groove at one end of the clamping block.

[0006] Preferably, a limiting groove is provided at one end of the slide, and a limiting groove adapted to the limiting block is installed at one end of the limiting rod.

[0007] Preferably, a threaded rod is threaded through and threaded to the side of the limiting rod, and a rotating block is installed at one end of the threaded rod.

[0008] Preferably, the top of the device body is provided with multiple scale lines, and the side of the device body is provided with multiple anti-slip grooves.

[0009] Preferably, a stop block is installed at one end of the main body of the device, a slot is installed at one end of the stop block, and a slot is provided on the side of the main body of the device to match the slot.

[0010] Preferably, one end of the spring is mounted on the inner wall of the inner cavity, and the other end of the spring is mounted on the clamping block.

[0011] Preferably, the limiting rod is slidably installed in the slide groove, and the side of the limiting rod abuts against one end of the wiring block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By setting up terminal blocks and wire grooves, when it is necessary to connect the electricity meter, the positions of multiple wires are determined by multiple terminal blocks. One end of the wire is placed through the wire groove, and the side of the wire groove abuts against the arc groove. The clamping block slides in the inner cavity, and the spring is compressed. When the wire groove is inserted, the spring rebound drives the clamping block to return to its original position and abut against the side of the wire groove to clamp and fix the wire groove, which helps the operator determine the position of wires such as ABCN.

[0014] (2) By setting a stop block and a slot, when the position of the wiring block is roughly determined, the rotating block drives the threaded rod to rotate, thereby driving multiple limit rods to move in the slide. The limit rods move at equal distances under the limit of the limit block, so that the range of motion of two adjacent wiring blocks in the slide is the same. When it is necessary to remove the wiring block, the side of the stop block is pulled to separate the slot from the block, and multiple wiring blocks are removed from the slide by continuously rotating the threaded rod.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an auxiliary device for wiring and positioning of an electricity meter, comprising a main body 1, a sliding groove 2 inside the main body 1, multiple limiting rods 3 installed in the sliding groove 2, multiple wiring blocks 4 slidably installed in the sliding groove 2, an indicator light 5 installed at one end of each wiring block 4, a wire-passing groove 6 inside the wiring block 4, a communicating inner cavity 7 at one end of the wire-passing groove 6, a spring 8 inside the inner cavity 7, a clamping block 9 installed at one end of the inner cavity 7, and an arc groove 10 at one end of the clamping block 9. One end of the slide groove 2 has a limiting groove 11. One end of the limiting rod 3 is fitted with a limiting groove 11 that matches the limiting block 12. A threaded rod 13 is threaded through and connected to the side of the limiting rod 3. A rotating block 19 is installed at one end of the threaded rod 13. One end of the spring 8 is installed on the inner wall of the inner cavity 7, and the other end of the spring 8 is installed on the clamping block 9. The limiting rod 3 is slidably installed in the slide groove 2. The side of the limiting rod 3 abuts against one end of the wiring block 4. When the electricity meter needs to be wired, the indicators on the multiple wiring blocks 4 will... Light 5 can display letters to help operators determine the connection positions of ABCN wires. The main body 1 of the device is placed at one end of the electricity meter. The placement position is determined by observing the scale line 14. By rotating the rotating block 19, multiple limit rods 3 slide in the slide groove 2. One end of the limit rod 3 is limited by the limit block 12. When moving, they are evenly distributed, thereby driving multiple terminal blocks 4 to move. The terminal blocks 4 are limited by two adjacent limit rods 3, fixing the movement range of the terminal blocks 4. By inserting the wire into the wire groove 6, the side of the wire will abut against the arc groove 10, causing the clamping block 9 to slide in the inner cavity 7. The spring 8 is compressed. After the wire groove 6 is installed, the spring 8 rebounds and causes the clamping block 9 to return to its original position, thereby clamping and fixing the side of the wire groove 6. The operator can fix multiple wires in different terminal blocks 4 to determine the initial position, which will not cause confusion during installation. The position of the terminal blocks 4 can also be adjusted by adjusting the position of the limit rod 3, thereby better adapting to the position of the electricity meter.

[0022] Example 2: Figure 2 and 3 As shown, the top of the device body 1 has multiple scale lines 14, the side of the device body 1 has multiple anti-slip grooves 15, one end of the device body 1 is equipped with a stop block 16, one end of the stop block 16 is equipped with a slot 17, and the side of the device body 1 is equipped with a locking block 18 that matches the slot 17. When it is necessary to remove the wiring block 4, the slot 17 is separated from the locking block 18 by moving one end of the stop block 16. By continuously rotating the rotating block 19, multiple limiting rods 3 are moved to the outside of the device body 1 to remove the limiting rods 3 and the wiring block 4. The remaining features are the same as in Embodiment 1.

[0023] The working principle is as follows: When wiring the electricity meter is required, the indicator lights 5 on multiple wiring blocks 4 can display letters to help the operator determine the connection position of the ABCN wires. The main body 1 of the device is placed at one end of the electricity meter, and the placement position is determined by observing the scale line 14. By rotating the rotating block 19, multiple limit rods 3 are driven to slide in the slide groove 2. One end of the limit rod 3 is limited by the limit block 12. When moving, they are evenly distributed, thereby driving multiple wiring blocks 4 to move. The wiring blocks 4 are limited by two adjacent limit rods 3, fixing the movement range of the wiring blocks 4. By inserting the wire into the wire groove 6, the side of the wire will abut against the arc groove 10, causing the clamping block 9 to slide in the inner cavity 7. The spring 8 is compressed. After the wire groove 6 is installed, the spring 8 rebounds. The moving clamp 9 returns to its original position, thereby clamping and fixing the side of the wire groove 6. The operator can fix multiple wires in different wiring blocks 4 to determine the initial position, which will not cause confusion during installation. The position of the wiring block 4 can also be adjusted by adjusting the position of the limit rod 3, so as to better match the position of the energy meter. The anti-slip groove 15 on the side of the device body 1 can increase the friction when the operator holds it to prevent slippage. When it is necessary to remove the wiring block 4, the slot 17 is separated from the block 18 by moving one end of the stop block 16. By continuously rotating the rotating block 19, multiple limit rods 3 are moved to the outside of the device body 1 to remove the limit rods 3 and wiring blocks 4. This makes it easy to install the number of limit rods 3 and wiring blocks 4 as needed, improving the applicability of the device body 1.
