[0002] A detachable leakage current detection probe is a tool used to detect leakage current in electrical equipment or cable systems. Its design allows users to easily remove and replace probe parts, and it is commonly used in electrical inspections and maintenance to ensure equipment safety.

[0003] The existing detachable leakage current detection probe mainly consists of a probe body and a connecting wire installed at one end of the probe body. When connecting the probe body to the leakage current detector, the plug with the end of the connecting wire facing away from the probe body is directly inserted into the connection socket on the leakage current detector body, thereby realizing convenient installation of the probe body and the leakage current detector.

[0004] While existing detachable leakage current detection probes can be quickly installed by direct insertion, the probe body mainly relies on friction after insertion for positioning. This not only poses a risk of the probe body becoming loose and falling off the leakage current detector body, but also has the drawback of incomplete insertion, resulting in significant errors in leakage current detection and hindering stable use of the probe body. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a detachable leakage current detection probe quick-installation device that can automatically limit the position between the probe body and the leakage current detector body after insertion, prevent the probe body from loosening and falling off during the leakage current detection process, and ensure that the probe body and the leakage current detector body can be quickly connected in place.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the existing detachable leakage current detection probe will first be introduced.

[0025] The existing detachable leakage current detection probe mainly consists of a probe body and a connecting wire installed at one end of the probe body. When connecting the probe body to the leakage current detector, the plug with the end of the connecting wire facing away from the probe body is directly inserted into the connection socket on the leakage current detector body, thereby realizing convenient installation of the probe body and the leakage current detector.

[0026] Please see Figures 1-4 This application discloses a detachable leakage current detection probe quick-installation device, comprising a leakage current detector body 1. Two connecting wires 3 are provided on one side of the leakage current detector body 1. Each connecting wire 3 is connected to a probe body 4 at its end facing away from the leakage current detector body 1. A quick-installation assembly 6 is installed between each connecting wire 3 and the leakage current detector body 1. The quick-installation assembly 6 includes a plug 61, a limiting groove 62, a ramp 63, a wedge block 64, a connecting post 65, a spring 66, a pull cap 67, and a socket 68. The socket 68 is installed at the wiring port on the leakage current detector body 1, and the pull cap 67... Installed at the top center of the plug 68, the connecting post 65 is installed at the top center of the inner top of the pull cap 67, the wedge block 64 is connected to the bottom of the connecting post 65, the spring 66 is installed on the wedge block 64 located outside the connecting post 65, the plug 61 is connected to the end of the connecting wire 3 facing the leakage current detector body 1, the limiting groove 62 is opened on one side of the top of the plug 61, and the ramp 63 is reserved at one corner of the top of the plug 61; a guide push assembly 7 is also installed between the plugs 61, the guide push assembly 7 includes the second spring 71, the T-shaped slider 72, the push block 73, the mounting hole 74, the T-shaped slide groove 75, and the push rod 76.

[0027] Specifically, when connecting the connecting wire 3 on the probe body 4 to the leakage current detector body 1, the plug 61 is directly inserted into the socket 68. After the plug 61 enters the socket 68, the ramp 63 on the plug 61 will fit against the inclined surface on the lower side of the wedge block 64. As the plug 61 is continuously inserted, the wedge block 64 will be pushed upward. When the plug 61 is fully inserted into the socket 68, the limiting groove 62 is exactly aligned with the wedge block 64. At this time, the spring 66 is in a compressed state. Under the rebound and reset action of the spring 66, the wedge block 64 will be pushed in. The limiting groove 62 is used to reliably limit the insertion of the plug 61 and the socket 68 after insertion. When the plug 61 is inserted into the socket 68, the T-shaped slider 72 and the T-shaped groove 75 cooperate to ensure that the plug 61 is inserted more smoothly and without any tilting. When the probe body 4 is disassembled and replaced, simply pull up the pull cap 67, and under the action of the spring 71 and the push block 73, the push rod 76 is separated from the mounting hole 74, so that the plug 61 can be quickly ejected from the socket 68, ensuring the quick disassembly and replacement of the probe body 4.

[0028] Please see Figures 1-3The T-shaped groove 75 is opened in the middle of the bottom end of the insert 68, and the push rod 76 is installed in the middle of the T-shaped groove 75 along the length of the T-shaped groove 75.

[0029] As one implementation, the T-shaped groove 75 cooperates with the T-shaped slider 72 to ensure that the plug 61 slides more smoothly when it is inserted into the socket 68.

[0030] Please see Figure 3 The T-shaped slider 72 is installed at the bottom of the plug 61, directly opposite the T-shaped groove 75, and the mounting hole 74 is opened on the T-shaped slider 72, directly opposite the top rod 76.

[0031] As one implementation method, the mounting hole 74 cooperates with the push rod 76, which not only serves as a secondary guide, but also enables the plug 61 to pop out quickly during disassembly.

[0032] Please see Figure 3 and Figure 4 One end of spring 71 is inserted into mounting hole 74, and the other end of spring 71 is inserted into push block 73. Push block 73 is in sliding fit with mounting hole 74.

[0033] In one implementation, when the push rod 76 is inserted into the mounting hole 74, the second spring 71 is in a compressed state. If the plug 61 is not limited at this time, the plug 61 will pop out from the socket 68. When the limit on the upper side of the plug 61 is released, the mounting hole 74 will be separated from the push rod 76 under the action of the second spring 71 and the push block 73, thereby realizing the quick separation and replacement of the plug 61 and the socket 68.

[0034] Please see Figure 3 The push rod 76 is slidably fitted with the mounting hole 74, and the push rod 76 has a cylindrical structure.

[0035] As one implementation method, the sliding fit installation method can ensure stable movement and adjustment between the top rod 76 and the mounting hole 74.

[0036] Please see Figures 1-3 The shape of the limiting groove 62 matches the shape of the bottom end of the wedge block 64, and the slope of the inclined surface of the wedge block 64 is consistent with the slope of the inclined slope 63.

[0037] In one implementation, the slope of the wedge block 64 is made to match the slope of the ramp 63, so that the plug 61 can be inserted into the socket 68, ensuring that the ramp 63 can fit against the slope of the lower side of the wedge block 64.

[0038] Please refer to 3. The top of the sleeve 68 is hollow, directly opposite the wedge block 64. The wedge block 64 and the sleeve 68 slide together.

[0039] As one implementation method, the hollow structure at the top of the socket 68 facilitates the easy upward movement and retraction of the wedge block 64.

[0040] Please see Figures 2-4 The top of the connecting post 65 is bonded to the pull cap 67, and the bottom of the connecting post 65 is bonded to the wedge block 64. The spring 66 is inserted into the pull cap 67 and the sleeve 68. The connecting post 65 passes through the spring 66.

[0041] In one implementation, spring 66 is mainly used to realize the automatic springback reset of wedge block 64 after it moves upward, and connecting post 65 can ensure that wedge block 64 is synchronously adjusted with pull cap 67.

[0042] Please see Figure 1 The top of the leakage current detector body 1 is also equipped with a display screen 2, and the top of the leakage current detector body 1 is equipped with operation buttons 5 located on the side of the display screen 2.

[0043] As one implementation method, the lower display screen 2 is mainly used to display the results of leakage current detection, and the operation button 5 is mainly used to adjust the functions of the leakage current detector body 1.

[0044] The specific working principle is as follows: When connecting the connecting wire 3 on the probe body 4 to the leakage current detector body 1, the plug 61 is directly inserted into the socket 68. After the plug 61 enters the socket 68, the ramp 63 on the plug 61 will fit against the inclined surface on the lower side of the wedge block 64. As the plug 61 is continuously inserted, the wedge block 64 will be pushed upward. When the plug 61 is fully inserted into the socket 68, the limiting groove 62 is exactly aligned with the wedge block 64. At this time, the spring 66 is in a compressed state. Under the rebound and reset action of the spring 66, the wedge block 64 will be pushed into the limiting groove 62 to achieve reliable positioning of the plug 61 and the socket 68 after insertion. When the plug 61 is inserted into the socket 68, the T-shaped slider 72 and the T-shaped groove 75 cooperate to ensure that the plug 61 is inserted more smoothly and without any tilting. When disassembling and replacing the probe body 4, simply pull up the cap 67. Under the action of the spring 71 and the push block 73, the push rod 76 will separate from the mounting hole 74, allowing the plug 61 to pop out quickly from the socket 68. This ensures quick disassembly and replacement of the probe body 4. During the installation of the probe body 4, the plug 61 is directly inserted into the socket 68, achieving quick engagement between the limiting block and the limiting groove 62. This ensures quick positioning of the plug 61 and the socket 68 after connection, ensuring quick connection between the probe body 4 and the leakage current detector body 4. This prevents the probe body 4 from becoming loose or falling off during connection. Furthermore, due to this positioning structure, the plug 61 and the socket 68 are fully engaged after insertion, eliminating any possibility of incomplete insertion. This results in smaller errors during leakage current detection and facilitates stable use of the probe body 4.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
