Description

Technical Field

[0001] The utility model relates to the technical field of precise DC shunt metering devices, and in particular to a precise DC shunt metering device that is convenient for expansion and connection. Background Art

[0002] The power supply of communication networks is the key to telecommunication systems, especially in wireless communication networks. Base stations are important nodes that connect mobile phones to the network. The standard power supply configuration of communication base stations is a combination of AC power (220V AC) and batteries. This is because most of the equipment in the base station uses DC power. After the AC power enters the base station, it needs to be converted from AC to DC before it is provided to the power-consuming equipment. In addition, in order to reduce unnecessary duplication of construction, multiple network providers now share base stations, so there are multiple users in one base station. Therefore, a DC shunt metering device is generated to improve the accuracy of shunt metering, and its accuracy far exceeds the original fixed proportion allocation method.

[0003] The general operation method is that the staff installs the DC shunt metering device in a fixed machine room, then inserts the connecting line of the equipment to be measured into the interface of the DC shunt metering device, and then performs shunt metering.

[0004] Based on the above-mentioned related technologies, the applicant believes that inserting the connecting wires of the equipment to be measured into the interface of the DC shunt metering device and then performing shunt metering will result in more lines being connected to the metering device. The space in the machine room is limited, and it is inevitable that the staff will accidentally touch the connecting wires when walking and working, causing the connecting wires to loosen and fall off, affecting the measurement accuracy. To address the above problems, we have introduced a precise DC shunt metering device that is easy to expand connections. Utility Model Content

A handle 10 for pulling the stabilizing plate 507 is fixedly connected to the top of the stabilizing plate 507 .

[0026] In the above technical solution, considering that the staff may accidentally touch the connecting line 4 when walking and working, causing the connecting line 4 to loosen and fall off, affecting the measurement accuracy, in order to solve such problems, the specific operations are as follows:

[0027] Reference Figure 1 and Figure 4 In a preferred embodiment, the connector of the connecting line 4 of the device is inserted into the interface 3, and then the handle 10 is held by hand to rotate the stabilizing plate 507 by 90°, the connecting plate 505 is rotated 90° around the slider 504, and then the stabilizing plate 507 is pulled horizontally by hand to make the slider 504 slide on the outside of the slide bar 502, the spring 503 is compressed, and then the card slot 508 clamps the connecting line 4, and then the staff releases the hand pulling the handle 10. Under the tension of the spring 503, the card slot 508 stably clamps the connecting line 4 at the interface 3. The stabilizing mechanism is set up to stabilize and fix the connecting line 4, avoiding the situation where the connector of the connecting line 4 falls off from the inside of the interface 3 when accidentally touched by the staff, thereby ensuring the accuracy of the measurement and the stability of the expansion of the meter during use. The structure is simple and the practicability is strong.

[0028] Reference Figure 2 and Figure 5In a preferred embodiment, the heat dissipation component includes a heat dissipation window 11, which is provided at the bottom of the meter body 1.

The bottom of the bottom feet 2 is provided with a rubber pad for anti-slip and noise reduction. The size of the slider 504 is consistent with the size of the connecting groove 501.

[0030] Working principle: In actual use, the staff first takes the DC shunt metering device to the position where it is needed, and then inserts the connector of the device's connecting line 4 into the interface 3, and then holds the handle 10 with his hand to rotate the stabilizing plate 507 90°, and the connecting plate 505 rotates 90° around the slider 504, and then pulls the stabilizing plate 507 horizontally with his hand to make the slider 504 slide on the outside of the slide bar 502, the spring 503 is compressed, and then the card slot 508 clamps the connecting line 4, and then the staff releases the hand pulling the handle 10. Under the tension of the spring 503, the card slot 508 stably clamps the connecting line 4 at the interface 3. When the DC shunt metering device is working, heat is generated, and the heat is dissipated through the heat dissipation window 11. The dust cover 7 can reduce the external dust from entering the interior of the DC shunt metering device. When the dust cover 7 needs to be cleaned, it only needs to be taken out from the inside of the magnetic suction groove 6. After cleaning, inside the magnetic suction groove 6, at this point, the staff has completed the expansion and stabilization of the DC shunt metering device.
