[0025] Example 2, as Figure 4As shown, a cable insulation withstand voltage test protection fixture includes a base 1 made of POM material to prevent conductivity. The base 1 has a first groove 101 at the top and a second groove 102 at the bottom. The first groove is used to place the cable under test; the second groove is used to place the wires of the test equipment. A conductive block assembly 2 is provided in the first groove 101, and the conductive post 201 of the conductive block assembly 2 extends downward into the second groove 102. The cable under test and the wires of the test equipment are electrically connected through the conductive post 201. A top cover 3 matching the first groove 101 is provided on one side of the top of the base 1, and a buckle 5 for locking the top cover 3 is provided on the other side. The top cover is fixed to the top of the base by the buckle and seals the first groove. A floating plug block assembly 4 corresponding to the conductive block assembly 2 is provided on the top cover 3. The terminals of the cable under test are connected to the conductive block assembly 2. When the top cover 3 is closed, the floating plug block assembly 4 presses down and secures the terminals on the conductive block assembly, ensuring a stable connection between the terminals and the conductive block assembly during the test. This invention conceals exposed terminals internally through the first groove, the second groove, and the top cover on the base, preventing electric shock and improving testing safety. At the same time, the floating plug block assembly ensures stable connection and smooth conductivity of the terminals, improving testing stability.

[0026] like Figure 3 As shown, in this embodiment, the front panel of the base 1 has a first inlet slot communicating with the first groove 101, and the rear panel of the base 1 has a second inlet slot communicating with the second groove 102. The first inlet slot is used for the cable under test to enter the first groove 101, and the second inlet slot is used for the testing equipment to enter the second groove. In this embodiment, the first groove 101 is provided with two conductive block assemblies 2, namely an inner conductive block assembly 2-1 and an outer conductive block assembly 2-2. The inner conductive block assembly 2-1 and the outer conductive block assembly 2-2 are arranged in parallel, and the outer conductive block assembly 2-2 is close to the first groove 101. The terminals of the cable under test are divided into copper tube terminals and ground wire terminals. The copper tube terminals are connected to the conductive posts of the outer conductive block assembly, and the ground wire terminals are connected to the conductive posts of the inner conductive block assembly.

[0027] As a preferred option, such as Figure 5 , 6As shown, the conductive block assembly 2 in this embodiment includes a positioning plate 202, on which a positioning sleeve 203 is fixedly mounted. Two positioning sleeves are provided. The conductive post 201 is divided into a short post 2011 and a long post 2012, which are respectively positioned within their corresponding positioning sleeves 203. The positioning sleeves limit and fix the conductive post. The long post 2012 extends downward into the second groove 102 for connection to the test equipment wires. Both the short post 2011 and the long post 2012 extend upward into their corresponding positioning sleeves 203 for connection to terminals. Preferably, the positioning sleeve 203 of the inner conductive block assembly 2-1 is a cylindrical sleeve, while the positioning sleeve 203 of the outer conductive block assembly 2-2 is a rectangular sleeve. The rectangular sleeve is flush with the pressure plate, and the cylindrical sleeve extends slightly upward beyond the pressure plate to stably position the relatively soft grounding wire terminal. The two long posts extend into the second groove for connection to the two positive and negative wires of the test equipment.

[0028] In this embodiment, the bottom of the first groove 101 is provided with two mounting slots 103, which correspond to the inner conductive block assembly 2-1 and the outer conductive block assembly 2-2, respectively. The first groove 101 is connected to the second groove 102 through the mounting slots 103; this facilitates installation and ensures that the long conductive post can be smoothly inserted into the second groove. The conductive block assembly 2 is disposed in the mounting slot 103 and fixed to the base 1 by the pressure plate 6. The pressure plate 6 is fixed to the bottom of the first groove 101 by screws.

The positioning sleeve 203 of the outer conductive block assembly 2-2 is flush with the pressure plate to provide greater support for the long and short posts to accommodate the connection of the copper tube terminal; the two long and short posts of the positioning sleeve 203 of the inner conductive block assembly 2-1 are connected to the relatively soft ground wire terminal. The positioning sleeve 203 of the inner conductive block assembly 2-1 extends slightly upward from the pressure plate to facilitate contact with the bottom of the ground wire terminal and provide stable positioning for the ground wire terminal.

[0029] like Figure 7 As shown, in this embodiment, a baffle 104 is provided in the mounting slot 103, and the positioning plate 202 is located on the baffle 104 and is pressed into the mounting slot 103 by the pressure plate 6; to ensure the stable fixing of the positioning plate, the baffle method is adopted to facilitate installation and disassembly.

[0030] Example 3, as Figure 8As shown, a cable insulation withstand voltage test protection fixture is further optimized based on embodiment 1 or 2. In this embodiment, the floating plug block assembly 4 includes four insertable sleeves 401, each corresponding to one of the four conductive posts. A vertical limiting groove 301 is provided on the top cover 3, and the insertable sleeves 401 slide in conjunction with the vertical limiting groove 301. A retaining ring 302 is provided within the vertical limiting groove 301, and a spring 402 is provided between the retaining ring 302 and the insertable sleeves 401. The insertable sleeves 401 correspond one-to-one with the conductive posts 201 of the conductive block assembly 2. When the top cover is closed, the insertable sleeves are inserted into the conductive posts, and the spring design presses the insertable sleeves above the terminals to prevent poor contact during testing and ensure the stability of the test connection.

[0031] In this embodiment, the insertable sleeve 401 includes a sleeve portion 4011 and a rod portion 4012 fixedly connected. The sleeve portion 4011 and the rod portion 4012 can also be designed as an integral structure.

The rod portion 4012 has a threaded hole with a retaining bolt 403 inside, ensuring that the rod portion slides up and down relative to the retaining ring. A spring 402 is sleeved on the rod portion 4012 and located between the sleeve portion 4011 and the retaining ring 302. When the top cover is closed, the spring presses the insertable sleeve onto the conductive post, securing the terminals on the conductive post and ensuring the stability of the connection.

[0032] In this embodiment, a wall wire groove is provided on the column sleeve 4011 corresponding to the outer conductive block assembly 2-2; so as to avoid the cable and allow the copper tube terminal to fit better on the positioning sleeve, ensuring its conductivity and connection stability.

[0033] In this embodiment, the top cover 3 is preferably connected to the base 1 via an automatic spring hinge 7, enabling the top cover to automatically pop up. The buckle 5 is a push-type buckle, which can lock the top cover in time and preferably confine the cable within the first groove to prevent workers from touching it and causing electric shock.
