Description

Technical Field

[0001] This utility model relates to the field of power grounding detection technology, and more specifically, to a grounding detection mechanism for low-voltage power systems. Background Technology

[0002] In the modern energy supply system, the low-voltage power system, as a key link connecting the high-voltage power grid and end users, bears the important responsibility of providing stable power support for various scenarios such as industrial production, commercial operation, and residential life. The safety and reliability of its operation are directly related to the stable development of the national economy and the safety of people's lives and property. Therefore, fault detection and maintenance of the low-voltage power system has always been a core issue of concern in the power industry. Appropriate instruments and equipment are required for grounding detection of low-voltage power systems; however, existing technologies have the following shortcomings in their application:

[0003] Existing testing and calibration equipment has connection sockets for connecting corresponding plugs. However, there is generally no anti-dislodgement positioning mechanism on the outside of the connection sockets. When the plug is inserted into the connection socket, it is easy for the plug to be affected by external force and detach from the connection socket, affecting the use of the testing and calibration equipment. At the same time, at the connection point between the plug end and the wire, the wire is usually in a bent state. Over time, the connection point between the wire and the plug may be damaged or cracked, posing a certain safety hazard.

[0004] Therefore, there is an urgent need for a grounding detection mechanism for low-voltage power systems to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grounding detection mechanism for low-voltage power systems. It solves the problem that existing testing and calibration equipment typically has connection sockets for connecting plugs, but these sockets generally lack anti-detachment positioning mechanisms. When a plug is inserted into the connection socket, it is easily detached from the socket due to external force, affecting the use of the testing and calibration equipment. Furthermore, at the connection point between the plug end and the wire, the wire is usually bent, which may cause the wire to crack or break at the connection point over time.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The application is as follows:

[0008] A grounding detection mechanism for low-voltage power systems includes a detection and calibration instrument body. The front of the detection and calibration instrument body has two connection holes. A connection plug is inserted into the connection hole and a connection wire is installed on the connection plug. An anti-disengagement positioning mechanism is provided on the outside of both connection holes.

[0009] The anti-detachment positioning mechanism includes two mounting blocks fixedly installed on the front of the testing and calibrating instrument body. A first guide rod is slidably connected through the mounting blocks. A limit block is fixedly connected to one end of the first guide rod away from the connector plug. An arc-shaped anti-detachment block is fixedly connected to the other end of the first guide rod. A fixing block is fixedly connected to the top of each of the two arc-shaped anti-detachment blocks. A spring is fixedly connected between the arc-shaped anti-detachment block and the mounting block. An L-shaped block is fixedly connected to the bottom of one of the arc-shaped anti-detachment blocks. A first arc-shaped block is fixedly connected to the upper surface of the L-shaped block. A connecting block is fixedly connected to the front of the testing and calibrating instrument body. Two second guide rods are fixedly connected to the top of the connecting block. A T-shaped block is slidably connected to both second guide rods. A second arc-shaped block is fixedly connected to the lower surface of the T-shaped block. A tension spring is provided between the two second guide rods. An arc-shaped support block is fixedly connected to the upper surface of the T-shaped block.

[0010] As a preferred technical solution of this application, the spring is located outside the first guide rod, and the two ends of the tension spring are fixedly connected to the lower surface of the T-shaped block and the upper surface of the connecting block, respectively.

[0011] As a preferred technical solution of this application, one side surface of the arc-shaped anti-detachment block is in contact with the back of the connector plug.

[0012] As a preferred technical solution of this application, one side surface of the limiting block is in contact with the outer surface of the mounting block.

[0013] As a preferred technical solution of this application, both the first arc-shaped block and the second arc-shaped block are convex, and the outer surface of the first arc-shaped block abuts against the outer surface of the second arc-shaped block.

[0014] As a preferred technical solution of this application, the upper surface of the arc-shaped support block is an arc-shaped concave surface, the arc-shaped support block is located between two arc-shaped anti-detachment blocks, and the upper surface of the arc-shaped support block is in contact with the outer surface of the connecting wire.

[0015] As a preferred technical solution of this application, one side surface of the connector plug is in contact with the front of the test and calibration instrument body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The anti-detachment positioning mechanism can limit the connection plug when it is inserted into the connection socket, preventing the end of the connection plug from coming out of the connection socket, which is conducive to the normal use of the test calibrator.

[0018] 2. The anti-detachment positioning mechanism can limit the connection plug to prevent it from detaching, while the arc-shaped support block can support the connecting wire, preventing the connection between the connecting wire and the connection plug from being damaged or torn due to bending, thus ensuring the safety of the connection plug and connecting wire.

[0027] Example:

[0028] like Figure 1-4 As shown in the figure, this embodiment proposes a grounding detection mechanism for low-voltage power systems, including a detection and calibration instrument body 1. Two connection sockets are opened on the front of the detection and calibration instrument body 1, and a connection plug 3 is inserted into each socket. One side surface of the connection plug 3 is in contact with the front of the detection and calibration instrument body 1, and a connection wire 4 is installed on the connection plug 3. Anti-detachment positioning mechanisms are provided on the outer sides of both connection sockets. Each anti-detachment positioning mechanism includes two mounting blocks 5 fixedly installed on the front of the detection and calibration instrument body 1. A first guide rod 6 is laterally slidably connected through each mounting block 5. A limit block 7 is fixedly connected to one end of the first guide rod 6 away from the connection plug 3, and an arc-shaped anti-detachment block 8 is fixedly connected to the other end of the first guide rod 6. A [missing information - likely a device or component] is fixedly connected to the top of each of the two arc-shaped anti-detachment blocks 8. A spring 10 is fixedly connected between the fixed block 9, the arc-shaped anti-detachment block 8 and the mounting block 5. An L-shaped block 11 is fixedly connected to the bottom of one of the arc-shaped anti-detachment blocks 8. A first arc-shaped block 12 is fixedly connected to the upper surface of the L-shaped block 11. A connecting block 13 is fixedly connected to the front of the detection and calibration instrument body 1. Two second guide rods 14 are fixedly connected to the top of the connecting block 13. A T-shaped block 15 is slidably connected to the two second guide rods 14. A second arc-shaped block 2 is fixedly connected to the lower surface of the T-shaped block 15. A tension spring 16 is provided between the two second guide rods 14. The spring 10 is located outside the first guide rod 6. The two ends of the tension spring 16 are fixedly connected to the lower surface of the T-shaped block 15 and the upper surface of the connecting block 13, respectively. An arc-shaped support block 17 is fixedly connected to the upper surface of the T-shaped block 15.

[0029] First, push the two fixed blocks 9 in the anti-detachment positioning mechanism to move them away from each other. This causes the two fixed blocks 9 to move the two arc-shaped anti-detachment blocks 8 away from each other. The two first guide rods 6 follow the movement of the two arc-shaped anti-detachment blocks 8. The two springs 10 are compressed and deformed. The L-shaped block 11 and the first arc-shaped block 12 follow one of the arc-shaped anti-detachment blocks 8. During this process, the tension of the tension spring 16 causes the T-shaped block 15, the second arc-shaped block 2, and the arc-shaped support block 17 to move downwards, ensuring that the second arc-shaped block 2 and the first arc-shaped block 12 are always in contact. The two second guide rods 14 guide the T-shaped block 15. Then, insert the end of the connector 3 into the connector socket, ensuring that one side of the connector 3 is in contact with the front of the testing and calibration instrument body 1. Then, release the two fixed blocks 9. The elastic force of the two springs 10 causes the two... The movement of the arc-shaped anti-detachment block 8 brings the two arc-shaped anti-detachment blocks 8 closer to each other. The L-shaped block 11 and the first arc-shaped block 12 move and reset with one of the arc-shaped anti-detachment blocks 8. The two first guide rods 6 move synchronously with the two arc-shaped anti-detachment blocks 8 respectively, so that the two limit blocks 7 are respectively attached to the two mounting blocks 5. At this time, the two arc-shaped anti-detachment blocks 8 are located on the back of the connector plug 3, which can prevent the end part of the connector plug 3 from coming out of the connector socket, which is conducive to the normal use of the test calibrator body 1. At the same time, through the cooperation of the first arc-shaped block 12 and the second arc-shaped block 2, the T-shaped block 15 and the arc-shaped support block 17 can be driven to move upward, so that the upper surface of the arc-shaped support block 17 contacts the outer surface of the connecting wire 4, thereby preventing the connection between the connecting wire 4 and the connector plug 3 from being broken due to bending, and ensuring the safety of the connector plug 3 and the connecting wire 4.

[0030] The model of the test and calibration instrument body 1 in this application is WZJ-S. The test and calibration instrument body 1 is a known prior art, and its working principle and usage method will not be described in detail here.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, one side surface of the arc-shaped anti-detachment block 8 is in contact with the back of the connector plug 3, which can prevent the end part of the connector plug 3 from coming out of the connector socket, thus facilitating the normal use of the test calibrator body 1.

[0032] like Figure 2As shown, one side surface of the limiting block 7 is in contact with the outer surface of the mounting block 5. The first arc-shaped block 12 and the second arc-shaped block 2 are both convex, and the outer surface of the first arc-shaped block 12 abuts against the outer surface of the second arc-shaped block 2. The upper surface of the arc-shaped support block 17 is an arc-shaped concave surface. The arc-shaped support block 17 is located between the two arc-shaped anti-detachment blocks 8. The upper surface of the arc-shaped support block 17 is in contact with the outer surface of the connecting wire 4, which can prevent the connection between the connecting wire 4 and the connecting plug 3 from being broken due to bending, thus ensuring the safety of the connecting plug 3 and the connecting wire 4 in use.
