A wiring assembly for an electricity meter

Abstract

This application discloses a wiring assembly for an electricity meter, belonging to the field of electricity meter technology. It includes a junction box, fixedly installed inside the base of the electricity meter, with a wiring hole at the end of the junction box. This application utilizes a design where, when the top of the wiring terminal contacts an L-shaped elastic sheet, the L-shaped elastic sheet is compressed and bends into a receiving groove. When the bottom of the wiring terminal passes the top of the L-shaped elastic sheet, the L-shaped elastic sheet is no longer restricted by space and resets under its own elasticity. Then, the top of the L-shaped elastic sheet abuts against the bottom of the wiring terminal, limiting and fixing the current position of the wiring terminal. Therefore, it effectively solves the problem of the slider being inconvenient to operate at the bottom of the protective box and requiring multiple adjustments to the slider position. This achieves the effect of pre-limiting the wire with a simple action, improving installation efficiency.

Description

Technical Field

[0001] This application relates to the field of electricity meter technology, and more specifically, to an electricity meter wiring assembly. Background Technology

[0002] The wiring assembly of an electricity meter is a key component connecting the electricity meter to the external circuit. It is responsible for connecting the electricity meter to the power system to realize the measurement of electricity. It is the "bridge" for the normal operation of the electricity meter and directly affects the accuracy of measurement and the safety of electricity use.

[0003] In related technologies, the wiring holes of existing electricity meters are exposed for extended periods. When the meter is not in use, dust or other impurities can easily enter the wiring holes, affecting the internal electronic structure and impacting future use. Furthermore, wiring is inconvenient. To address this, for example, patent CN221465621U provides an electricity meter with convenient wiring. This device features a main body with evenly spaced wiring holes at its lower end. A wiring bolt is movably inserted into one side of each wiring hole. A protective box is fixedly installed at the end, located below the wiring hole. During wiring, the wire passes through the insertion hole and is inserted into the wiring hole. The user pushes the slider, which moves along the groove. The slider drives the rotating ring to rotate, and the rotating ring drives multiple rotating sleeves to rotate synchronously through the meshing tooth ring and bevel gear. Under the action of the thread, the clamping screw moves into the insertion hole as the rotating sleeves rotate, thus limiting the wire inside the insertion hole. This can limit one end of the wire inside the wiring hole, making it convenient for the user to turn the wiring bolt, facilitating wiring, and improving the wiring effect.

[0004] Although the existing technical solutions mentioned above insert the wire into the wiring hole and connect it with the wiring bolt, avoiding long-term exposure of the wiring hole and improving the wiring effect, the slider is located at the bottom of the protective box. By driving the slider to rotate along the slide groove, the clamping screw limits the wire to the insertion hole. In actual use, this process is not convenient to operate the slider to move, and each wire installation requires more time to adjust the slider position, which affects the installation efficiency of the wire.

[0005] In view of this, we propose a wiring assembly for an electricity meter. Utility Model Content

[0006] The purpose of this application is to provide a wiring assembly for an electricity meter that can effectively solve the problems in the prior art where the slider is located at the bottom of the protection box, making it inconvenient to operate and requiring multiple adjustments to the slider position. This assembly enables the wire to be pre-limited with a simple action, thereby improving installation efficiency.

[0007] This application provides a wiring assembly for an electricity meter, including:

[0008] A junction box is fixedly installed inside the base of the electricity meter. A wiring hole is provided at the end of the junction box, and a clamping plate groove is provided on the side wall of the wiring hole.

[0009] A fixing box is fixedly installed at the bottom of the base of the electricity meter. The fixing box has an insertion hole at its end. A wiring terminal is detachably installed on the side wall of the insertion hole. A storage groove is opened on the side wall of the insertion hole. An L-shaped elastic piece is fixedly installed on the side wall of the storage groove for abutting against the bottom of the wiring terminal.

[0010] The clamping plate is slidably disposed inside the clamping plate groove and is driven by external force to clamp and fix the wiring terminal inside the wiring hole.

[0011] As an optional solution to the technical solution of this application, a pull rod is slidably provided inside the fixing box, and a metal pull rope is fixedly provided at the end of the pull rod near the L-shaped elastic piece. The metal pull rope is fixedly connected to the L-shaped elastic piece, and a pull ring is fixedly provided at the end of the pull rod away from the outside of the fixing box.

[0012] As an optional solution to the technical solution of this application, the pull rod is provided with symmetrical limit grooves on the outer side, and the pull rod is provided with limit protrusions along the limit grooves on the outer side, and the limit protrusions are fixedly provided on the outer side of the fixing box.

[0013] As an optional solution to the technical solution of this application, the L-shaped elastic sheet is made of metal, and an insulating sleeve is fitted onto the top of the L-shaped elastic sheet.

[0014] As an optional solution to the technical solution of this application, a push groove is provided on the side of the clamping plate groove away from the wiring hole, and a locking groove is symmetrically provided on the inner side of the push groove;

[0015] A push rod is fixedly installed on the outside of the clamping plate, and a push-pull handle is fixedly installed on the end of the push rod away from the clamping plate. A rubber protrusion is fixedly installed on the outside of the push rod corresponding to the slot inside the push groove, and the rubber protrusion is engaged with the slot.

[0016] As an optional solution to the technical solution of this application, the wiring hole is aligned with the socket, and the inner wall of the wiring hole is provided with a contact piece that is electrically connected to the electricity meter.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] (1) This application adopts the method that when the top of the terminal contacts the L-shaped elastic sheet, the L-shaped elastic sheet is squeezed into the storage groove by space. When the bottom of the terminal passes the top of the L-shaped elastic sheet, the L-shaped elastic sheet is not restricted by space and resets under its own elasticity. Then the top of the L-shaped elastic sheet abuts against the bottom of the terminal and limits and fixes the current position of the terminal. Therefore, it effectively solves the problem that the slider is inconvenient to operate when it is at the bottom of the protective box and the slider position needs to be adjusted many times. Thus, it can achieve the effect of pre-limiting the wire with a simple action and improving the installation efficiency.

[0019] (2) When it is necessary to disassemble the terminal block, the pull ring is fastened and moved outward, which drives the pull rod and metal pull rope to move outward as well. After moving a certain distance, the metal pull rope pulls the L-shaped elastic piece to bend it and store it in the storage groove, thereby relieving the L-shaped elastic piece from its abutting effect on the bottom of the terminal block. Then, the wire is pulled down to drive the terminal block to slide down and complete the disassembly operation. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 5 This application discloses a wiring assembly for an electricity meter, including a junction box 1, a fixing box 2, a clamping plate 3, and a terminal block 22. The junction box 1 is fixedly disposed inside the electricity meter base 100. The top of the electricity meter base 100 has a mounting groove 101 for fixing the junction box 1. The end of the junction box 1 has a wiring hole 11, and the side wall of the wiring hole 11 has a clamping plate groove 12. The fixing box 2 is fixedly disposed at the bottom of the electricity meter base 100. The end of the fixing box 2 has a socket 21, and the side wall of the socket 21 is detachably provided with a terminal block 22. There is a storage groove 23, and an L-shaped elastic piece 24 is fixedly installed on the side wall of the storage groove 23 for abutting against the bottom of the terminal 22. The clamping plate 3 is slidably installed inside the clamping plate groove 12 and is driven by external force to clamp and fix the terminal 22 inside the wiring hole 11. The wiring hole 11 and the inner side of the energy meter base 100 are slidably connected to the terminal 22. The L-shaped elastic piece 24 is made of metal and an insulating sleeve 25 is fitted on the top of the L-shaped elastic piece 24. The wiring hole 11 is aligned with the socket 21. The inner wall of the wiring hole 11 is provided with a contact piece that is electrically connected to the energy meter.

[0028] Before wiring, insert the wire into the terminal 22 for connection. Then, insert the terminal 22 from the bottom of the fixing box 2 into the socket 21. During insertion, when the top of the terminal 22 contacts the L-shaped elastic piece 24, the L-shaped elastic piece 24 is squeezed into the storage groove 23 by the space. When the bottom of the terminal 22 passes the top of the L-shaped elastic piece 24, since the wiring hole 11 is aligned with the terminal 22, the top of the terminal 22 can be directly inserted into the wiring hole 11 through the energy meter base 100 and is in a suitable connection position. At this time, the L-shaped elastic piece 24 is not restricted by space and resets under its own elasticity. Then, the top of the L-shaped elastic piece 24 abuts against the bottom of the terminal 22 to limit and fix the current position of the terminal 22, achieving the effect of pre-positioning. At the same time, the insulating sleeve 25 set on the top of the L-shaped elastic piece 24 has an insulating effect to prevent the conduction of current in the terminal 22. Then, the clamping plate 3 is driven by external force to approach and squeeze the terminal 22 to clamp and fix the terminal 22, completing the wiring installation.

[0029] Reference Figure 4 and Figure 5 A pull rod 26 is slidably provided inside the fixed box 2. A metal pull rope 27 is fixedly provided at one end of the pull rod 26 near the L-shaped elastic piece 24. The metal pull rope 27 is fixedly connected to the L-shaped elastic piece 24. A pull ring 28 is fixedly provided at one end of the pull rod 26 away from the outside of the fixed box 2. Limiting grooves 29 are symmetrically provided on the outside of the pull rod 26. Limiting protrusions 210 are slidably provided inside the limiting grooves 29. The limiting protrusions 210 are fixedly provided on the outside of the fixed box 2.

[0030] When it is necessary to disassemble the terminal 22, by fastening the pull ring 28 and moving it outward, the pull rod 26 and the metal pull rope 27 are also moved outward. After moving a certain distance, the metal pull rope 27 pulls the L-shaped elastic piece 24 to bend it and store it in the storage groove 23, thereby releasing the abutment of the L-shaped elastic piece 24 against the bottom of the terminal 22. Then, by pulling the wire downward, the terminal 22 can slide down and complete the disassembly operation. At the same time, during the sliding process of the pull rod 26, the sliding distance of the pull rod 26 is limited by the length limitation of the limiting groove 29 and the blocking effect of the limiting protrusion 210, so as to prevent the pull rod 26 from falling off.

[0031] Reference Figure 1 and Figure 3 A push groove 13 is provided on the side of the clamping plate groove 12 away from the wiring hole 11. A slot 14 is symmetrically provided on the inner side of the push groove 13. A push rod 31 is fixedly provided on the outer side of the clamping plate 3. A push handle 32 is fixedly provided on the end of the push rod 31 away from the clamping plate 3. A rubber protrusion 33 is fixedly provided on the outer side of the push rod 31 corresponding to the slot 14 on the inner side of the push groove 13. The rubber protrusion 33 is engaged with the slot 14.

[0032] By pushing the push-pull handle 32 to slide towards the junction box 1, the push rod 31 pushes the clamping plate 3 towards the terminal 22 in the wiring hole 11 and squeezes it. As the push rod 31 slides in the push groove 13, when the rubber protrusion 33 slides to the corresponding slot 14, the rubber protrusion 33 and the slot 14 complete the engagement connection, fixing the position of the push rod 31, so that the clamping plate 3 keeps clamping and fixing the terminal 22, achieving the effect of multiple sets of synchronous clamping and fixing.

[0033] In summary, when using the electricity meter wiring assembly disclosed in this application, before wiring, the wire is first inserted into the terminal block 22 for connection. Then, the terminal block 22 is inserted from the bottom of the fixing box 2 into the socket 21. During the insertion process, when the top of the terminal block 22 contacts the L-shaped elastic piece 24, the L-shaped elastic piece 24 is squeezed into the receiving groove 23 by space. When the bottom of the terminal block 22 passes the top of the L-shaped elastic piece 24, since the wiring hole 11 is aligned with the terminal block 22, the top of the terminal block 22 can be directly aligned and inserted. The L-shaped elastic piece 24 is not restricted by space and resets under its own elasticity. Then, the top of the L-shaped elastic piece 24 abuts against the bottom of the terminal 22, limiting and fixing the current position of the terminal 22 to achieve the pre-positioning effect. At the same time, the insulating sleeve 25 on the top of the L-shaped elastic piece 24 provides insulation to prevent current conduction in the terminal 22. Subsequently, the clamping plate 3 is driven by external force to move closer to and press the terminal 22, clamping and fixing the terminal 22 to complete the connection. When the wiring is installed and the terminal 22 needs to be removed, the pull ring 28 is engaged and moved outward, which in turn moves the pull rod 26 and the metal pull rope 27 outward. After moving a certain distance, the metal pull rope 27 pulls the L-shaped elastic piece 24, causing it to bend and be stored in the storage groove 23. This releases the L-shaped elastic piece 24 from its abutment against the bottom of the terminal 22. Then, pulling the wire downward will cause the terminal 22 to slide down, completing the removal operation. At the same time, during the sliding of the pull rod 26, it is limited by the length of the limiting groove 29 and the limiting protrusion 210. The blocking effect limits the sliding distance of the pull rod 26, preventing the pull rod 26 from falling off. By pushing the push-pull handle 32 to slide towards the junction box 1, the push rod 31 pushes the clamping plate 3 towards the terminal 22 in the wiring hole 11 and squeezes it. As the push rod 31 slides in the push groove 13, when the rubber protrusion 33 slides to the corresponding slot 14, the rubber protrusion 33 and the slot 14 complete the engagement connection, fixing the position of the push rod 31, so that the clamping plate 3 keeps clamping and fixing the terminal 22, achieving the effect of multiple sets of synchronous clamping and fixing.
