Description

Technical Field

[0001] This utility model relates to the field of power meter technology, and in particular to a power meter with stable wiring. Background Technology

[0002] In power monitoring systems, the wiring stability of power meters has a significant impact on the measurement accuracy and operational reliability of the entire system. To achieve accurate and stable measurement and monitoring of power parameters, dedicated power meters are typically required. These meters usually include measurement modules, wiring terminals, and auxiliary function modules such as signal processing. Especially during field installation, with frequent wiring operations, the ease of wiring and connection stability of the meter itself directly affects installation efficiency and measurement accuracy. Therefore, developing an integrated, reliable, and easy-to-operate quick-wiring power meter has become an important direction for the technological improvement of power measurement equipment.

[0003] In existing technologies, instruments used for power measurement generally include a metering module, a display unit, and a terminal block structure. Structurally, the instrument has wiring ports for connecting wires, using screw crimping or plug-in methods to achieve electrical connections; it is also equipped with an insulating protective cover to prevent safety hazards caused by exposed live parts. In practical use, the terminals are usually fixedly connected to the instrument housing. Quick wiring requires tools to tighten them one by one, and the conductive contact surfaces and fixing devices are mostly rigid structures, making adjustment inconvenient, time-consuming, and difficult to achieve a quick and stable connection of the wires.

[0004] However, existing power meters still have certain problems in practical applications. On the one hand, during power testing, it is necessary to repeatedly switch the wiring configuration of the power meter. Traditional structures cannot quickly and stably connect the wiring, affecting the power testing work. On the other hand, it is inconvenient to view the test data during testing. These problems reduce the operational efficiency and convenience of power meters, and there is an urgent need to optimize the structural design. Therefore, a power meter with stable wiring is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a power meter with stable wiring, aiming to improve the problem that existing power meters cannot quickly and stably connect wires, thus affecting the efficiency of testing work.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power meter with stable wiring, including a housing, an inlet pipe inside the housing, a terminal block inside the inlet pipe, a wiring assembly inside the inlet pipe, and a support assembly inside the housing; The wiring assembly includes a push plate, the inner wall of which is slidably connected to the outer wall of the inlet pipe. A retaining ring is fixedly connected to the outer wall of the inlet pipe. A spring is sleeved on the outer wall of the inlet pipe. One end of the spring is fixedly connected to the outer wall of the inlet pipe, and the other end of the spring is fixedly connected to the inner wall of the push plate. A slider is slidably connected inside the inlet pipe. A recycling groove is opened inside the push plate, and the outer wall of the slider slides inside the recycling groove.

[0007] As a further description of the above technical solution: The support assembly includes a support bar, which is disposed inside the housing.

[0008] As a further description of the above technical solution: The outer shell has two rotating columns fixedly connected inside, and the outer wall of the support bar is rotatably connected to the outer wall of the two rotating columns.

[0009] As a further description of the above technical solution: A rotating column is fixedly connected inside the support bar, and a fixed bar is rotatably connected to the outer wall of the rotating column. The outer wall of the fixed bar slides inside the outer shell.

[0010] As a further description of the above technical solution: The outer wall of the outer shell is fixedly connected to a second locking block, and the inside of the second locking block is rotatably connected to a locking post.

[0011] As a further description of the above technical solution: The outer wall of the outer shell is fixedly connected to a locking block, and the outer wall of the locking post slides inside the locking block.

[0012] As a further description of the above technical solution: The card block has a baffle that is slidably connected inside, and a column is connected to the bottom of one end of the baffle.

[0013] As a further description of the above technical solution: The outer wall of the column is fitted with a second spring. One end of the second spring is fixedly connected to one end of the baffle, and the other end of the second spring is fixedly connected to the inside of the first locking block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the push plate is first pushed inward, and then the terminal block is pushed into the inside of the inlet pipe. The slider has an inclined structure. When the terminal block is pushed in, it slides over the outer wall of the slider and pushes the slider into the recycling groove. After the terminal block is pushed to the designated position, the push plate is released, and the push plate slides over the surface of the slider and pushes the slider into the groove inside the terminal block, thereby fixing the terminal block and the inlet pipe. This achieves the effect of quickly and stably fixing the terminal block and the inlet pipe, solving the problem that the power instrument cannot be quickly and stably wired, which affects the efficiency of the detection work, and improving the stability of the power instrument.

[0015] 2. In this utility model, the support bar and the fixing bar are first rotated out of the shell. After rotating the support bar and the fixing bar to a suitable angle, the fixing bar is inserted into the slot opened in the shell, so that the support bar, the fixing bar and the shell form a triangle, which achieves the effect of supporting the shell to view the test data. This solves the problem that the test data cannot be easily viewed when using the power instrument, and improves the convenience of the power instrument. Attached Figure Description

[0020] Working principle: When wiring this power meter, first push the push plate 2 inward. The push plate 2 compresses the spring 6, pushing the recycling groove 8 inside the push plate 2 to one end of the slider 7. Then push the terminal 3 into the inside of the inlet pipe 4. The slider 7 has an inclined structure. When the terminal 3 is pushed in, it slides over the outer wall of the slider 7 and pushes the slider 7 into the recycling groove 8. After pushing the terminal 3 to the designated position, release the push plate 2. Under the rebound action of the spring 6, the push plate 2 returns to its original position. The push plate 2 slides over the surface of the slider 7 and pushes the slider 7 into the groove inside the terminal 3, thereby fixing the terminal 3 and the inlet pipe 4. This achieves the effect of quickly and stably fixing the terminal 3 and the inlet pipe 4.

[0021] When data needs to be viewed during measurement, first pull the baffle 12 outward, compressing the second spring 14. Then lift the locking pin 11 upward and rotate it, thus sliding the locking pin 11 out of the locking block 9. Then rotate the support bar 15 and the fixing bar 16 out of the outer shell 1. After resetting the locking pin 11, release the baffle 12. Under the action of the second spring 14, the baffle 12 will be reset. Then rotate the support bar 15 and the fixing bar 16 to a suitable angle and insert the fixing bar 16 into the slot opened in the outer shell 1, so that the support bar 15, the fixing bar 16 and the outer shell 1 form a triangle, achieving the effect of supporting the outer shell 1 to view the test data.
