The heart-shaped ring connector 14 has a hollow U-shaped groove 21 inside. When the heart-shaped ring 5 is installed, the U-shaped groove 21 is embedded into the outer periphery of the first hanger 3 or the second hanger 4.

[0028] The first hanger 3 and the second hanger 4 are U-shaped hangers. Before installation, the heart-shaped ring 5 is installed around the first hanger 3 and the second hanger 4. The top of the first hanger 3 is provided with a left end 10 and a right end 11. The outer surface of the left end 10 and the right end 11 is provided with an external connecting port 20. The left end 10 and the right end 11 of the first hanger 3 are inserted into the first insertion port 17 from the bottom surface of the connector 1. The hanger connecting port 12 is a thread on the outer surface of the left end 10 and the right end 11. After insertion, the hanger nut 13 is installed at the hanger connecting port 12 of the left end 10 and the right end 11 to complete the installation of the first hanger 3. The first hanger 3 and the second hanger 4 have the same structure.

The bottom of the vertical force transmission rod 2 is provided with a lower rod body 8, and the outer connection port 20 is provided around the lower rod body 8. When installing the vertical force transmission rod 2, the lower rod body 8 is inserted from the top of the top insertion port 19. After the lower rod body 8 protrudes from the bottom of the connector 1, the installation nut 9 is installed from the bottom of the lower rod body 8 to complete the installation of the vertical force transmission rod 2. A hook 16 is installed at the hanging hole 7 at the top of the vertical force transmission rod 2 to connect the vertical force transmission rod 2 to one end of the horizontal tensile testing machine.

If all indicators of the test hardware meet the standard requirements, it is qualified.

[0030] like Figure 5 As shown, the heart-shaped ring mechanical performance testing fixture is installed on a hydraulic universal testing machine for testing. The vertical force transmission rod 2 is disassembled and replaced with a replacement part 22. The replacement part 22 is a bolt structure, with an external connection port 20 on its bottom outer surface. An installation nut 9 is installed around the external connection port 20.

[0031] The heart-shaped ring 5 is a commonly used power connector 1 cable accessory. Commonly used heart-shaped rings 5 on the market are TC-5, TC-7, TC-10, TC-12, TC-16, and TC-22. The specifications of the heart-shaped ring 5 are distinguished according to the rated load of the heart-shaped ring 5. These heart-shaped ring 5 specifications are suitable for different use scenarios and requirements, with different rated loads, suitable cable diameters, and weights. For example, the rated load of TC-5 is 50 kN, the suitable cable diameter is 16 mm, the connecting pin diameter is 2.3 mm, and the weight is 1.5 kg. As the rated load of the heart-shaped ring 5 increases, the weight increases, and the volume of the heart-shaped ring 5 increases, the internal space of the U-shaped groove 21 of the heart-shaped ring connector 14 also increases. The first hanger 3 and the second hanger 4 are made of solid steel bars. When the heart-shaped ring connector 14 is installed, the diameter of the steel bars that make up the first hanger 3 should be smaller than the size of the internal space of the U-shaped groove 21 of the heart-shaped ring connector 14. The heart-shaped ring connector 14 can be smoothly installed on the periphery of the first hanger 3. The diameter of the steel bars that make up the first hanger 3 should meet the installation requirements of the TC-5 heart-shaped ring 5. After meeting the installation requirements of the TC-5 heart-shaped ring 5, the first hanger 3 can at least meet the mechanical performance test requirements of the TC-5, TC-7, TC-10, and TC-12 heart-shaped rings 5. As the rated load of the heart-shaped ring 5 increases, the weight increases, and the volume increases, the internal space of the U-shaped groove of the heart-shaped ring connector 14 also increases. The first hanger 3 cannot meet the mechanical performance test requirements of the heart-shaped ring 5 with a larger rated load. The diameter of the solid steel bars that make up the second hanger 4 is greater than the diameter of the steel bars that make up the first hanger 3. The second hanger 4 is suitable for mechanical performance tests of heart-shaped rings 5 with a rated load greater than TC-12. The installation method of the heart-shaped ring 5 at the second hanger 4 is the same as the installation method of the heart-shaped ring 5 at the first hanger 3. The installation of the first hanger 3 and the second hanger 4 can be used for mechanical performance tests of at least six specifications of heart-shaped rings 5.

[0032] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and detail without departing from the scope defined by the claims of the present application.
