Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and more specifically, to an electricity meter with an electricity measuring structure. Background Technology

[0002] Electricity meters with a power measurement mechanism, commonly known as electricity meters, are used in power systems to measure and record electricity usage. Their primary and core function is to measure and record electricity consumption. Through electricity meters, users can clearly understand their electricity consumption over a certain period, enabling them to plan their electricity usage more rationally.

[0003] Among existing publicly available documents, patent publication number CN111413529A discloses a smart meter with a built-in hidden mechanism. This smart meter's power cord passes through the inlet hole on the right side of the meter box. An electric telescopic rod is located at both the top and bottom of the meter box, and is connected to a movable mounting plate. This invention allows one end of a drive key to be inserted into a gear, which rotates the gear, causing the outer baffle to move left and right, increasing the difficulty of opening the outer baffle and preventing children from easily opening it and causing safety hazards. However, this smart meter has the following shortcomings.

[0004] While smart meters with a power measurement structure can detect electricity consumption, the numerous connecting wires during wiring make it difficult to provide external and multi-point protection for multiple wires, resulting in poor protection. Therefore, a smart meter with a power measurement structure is needed. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a power meter with a measuring structure, comprising a wiring housing, a terminal block, and multiple wiring holes. The terminal block is fixed to one side of the wiring housing, and the multiple wiring holes are all opened at the bottom of the inner wall of the terminal block. A protective mechanism is provided on one side of the inner wall of the terminal block. The protective mechanism includes two energized posts fixedly disposed on one side of the inner wall of the terminal block. A connecting post is fixedly connected to one side of the outer wall of each energized post. A power meter is installed at one end of each connecting post, and both connecting posts are fixedly connected to the power meter. The power meter is fixedly connected to the wiring housing. An outer shell is provided above the terminal block. Side shells are fixedly connected to both sides of the outer shell. Multiple pressure blocks are fixedly installed at the top of the inner wall of the outer shell. An arc-shaped pressure strip is glued to the bottom of each pressure block, and multiple wire grooves are opened on one side of the inner wall of the outer shell.

[0006] Preferably, the two side shells are symmetrically arranged about the outer shell, the outer shell has an L-shaped vertical cross-section, and the side shells have a triangular vertical cross-section. Multiple pressure blocks are arranged equidistantly from right to left, and each arc-shaped pressure strip has a circular arc-shaped vertical cross-section. Threaded mounting screws are embedded on both sides of the wiring housing, and multiple mounting screws are arranged equidistantly from front to back.

[0007] In use, this technology involves inserting the wiring harness into multiple terminals on the terminal block, conducting electricity through the energized posts to the connecting posts, and then using a voltage meter to perform the voltage measurement operation. The outer casing protects the upper surface of the voltage meter, while the two side casings protect both sides of the terminal block. The wiring harness is clamped and locked by pressure blocks pressing against the arc-shaped pressure strip, allowing for the positioning and protection of multiple wiring harnesses.

[0008] Preferably, the upper surface of the outer casing is provided with a plug-in fixing mechanism; the plug-in fixing mechanism includes a compression electric cylinder fixedly mounted on the upper surface of the outer casing, two guide posts fixedly connected to the upper surface of the terminal block, and a compression strip fixedly connected to the output end of the compression electric cylinder. A rubber strip is adhered to one side of the compression strip, and two positioning groove rings are provided on one side of the rubber strip. Both positioning groove rings are fixedly connected to the outer casing. A positioning hole is provided on the inner wall of each positioning groove ring. A reinforcing block is provided on one side of the compression electric cylinder and fixedly connected to the outer casing. The reinforcing block is fixedly connected to the outer casing. The compression strip and the rubber strip are slidably connected to the outer casing. The rubber strip is made of rubber. The cross-sectional shape of the two positioning holes is circular. The rubber strip and the compression strip are slidably connected to the positioning groove rings.

[0009] In use, the outer shell guides the two guide pillars downwards along the outer wall of the outer shell. The positioning hole aligns with the outer wall of the guide pillar. The electric cylinder pushes the extrusion strip, which in turn pushes the rubber strip. The rubber strip then compresses along the inner wall of the positioning hole, thus compressing and fixing the two guide pillars.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This invention utilizes a protective mechanism to connect and install the terminal block by inserting the connecting wire harnesses into multiple wiring holes on the terminal block, enabling the voltage measuring meter to perform voltage measurement operations. By lowering the outer casing, the outer casing covers the upper surface of the voltage measuring meter for protection, while the two side shells protect both sides of the terminal block. The pressure block drives the arc-shaped pressure strip downwards, which presses against the connecting wire harnesses, providing positioning protection for multiple connecting wire harnesses and ensuring the safety of the voltage measuring structure of the meter.

[0012] 2. This utility model adopts a plug-in fixing mechanism. The outer shell moves downward along the outer wall of the two guide posts, and the positioning hole is connected to the outer wall of the guide post. The extrusion cylinder pushes the extrusion strip, and the rubber strip is extruded along the inner wall of the positioning hole. The rubber strip is extruded on the outer wall of the two guide posts to achieve the locking operation. Attached Figure Description

[0018] 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.

The specific structural configuration of the protection mechanism is as follows.

[0020] In this technical solution, as shown in the appendix Figure 1-3As shown, the terminal block 2 is fixed to one side of the terminal housing 1.

[0021] In this technical solution, as shown in the appendix Figure 1 As shown, threaded mounting screws 12 are embedded on both sides of the wiring housing 1. Multiple mounting screws 12 are arranged at equal intervals from front to back to facilitate fixing to the side of the wiring housing 1 using the mounting screws 12, so that the mounting screws 12 can be installed on the wiring housing 1.

[0022] In use, the meter with the electrical measuring structure is installed by inserting the connecting harness into the multiple wiring holes 3 on the terminal block 2. The terminal block 2 is then connected to the connecting post 5 via the energizing post 4, and the energizing post 5 supplies power to the meter 6, which then performs the electrical measurement operation. By lowering the outer casing 7, the two side casings 8 also move downwards, covering and protecting the upper surface of the meter 6. The two side casings 8 protect both sides of the terminal block 2. Simultaneously, multiple pressure blocks 9 move downwards, causing the arc-shaped pressure strip 10 to move downwards.

The compression strip 15 and the rubber strip 16 are slidably connected to the outer casing 7. The rubber strip 16 is made of rubber. The cross-sectional shape of the two positioning holes 18 is circular. Both the rubber strip 16 and the compression strip 15 are slidably connected to the positioning groove rings 17.

[0024] In this technical solution, the outer shell 7 is guided downward along the outer wall of the two guide posts 13, and the guide posts 13 slide along the inner wall of the positioning groove ring 17. The positioning hole 18 is connected to the outer wall of the guide post 13. The outer shell 7 is supported by the reinforcing block 19. The extrusion cylinder 14 pushes the extrusion strip 15, which pushes the rubber strip 16. The rubber strip 16 is extruded along the inner wall of the positioning hole 18. In this way, the rubber strip 16 is extruded onto the outer wall of the two guide posts 13, thereby extruding and fixing the two guide posts 13.
