[0015] Through the above technical solution, when the internally threaded tube rotates, it causes the torsion spring to twist and deform, when the steel cable loses traction, the torsion spring restores deformation to drive the internally threaded tube to rotate and reset.

[0016] Optionally, in the above-mentioned quick connection tooling for the copper busbar of the test cell's electrical performance load, an external thread adapted to the internally threaded tube is provided on the outer wall of the clamping rod, a rubber ring is fixedly arranged at one end of the clamping rod and the test joint, two limiting rods are symmetrically arranged on the outer wall of the rubber ring, limiting tubes opposite to the limiting rods are symmetrically arranged on the outer wall of the support plate, and the limiting rods are movably inserted into the inner walls of the limiting tubes.

[0021] When the operator inserts the test joint on the copper busbar plate and abuts against the driving member, the driving member is pushed downward to drive the fixing member to move, and then the test joint is fixed on the copper busbar plate through the fixing member. Therefore, it is more convenient to test the copper busbar plate;

Detailed Description of the Embodiment

[0027] The following will further elaborate on the present application Figures 1-3 with reference to the attached

[0028] Please refer to the drawings in the specification Figure 1 andFigure 2 and Figure 3 An embodiment provided by the present application: A rapid connection tooling for testing the electrical performance load copper bar of a fuel cell stack, including a front clamping plate 1, a rear clamping plate 2, a copper bar plate 3 and a test joint 4. The copper bar plate 3 is arranged between the front clamping plate 1 and the rear clamping plate 2. Grooves 21 for accommodating the copper bar plate 3 are provided on the opposite sides of the front clamping plate 1 and the rear clamping plate 2. Through the grooves 21, it is convenient for the operator to install the copper bar plate 3 between the front clamping plate 1 and the rear clamping plate 2.

[0029] A number of connecting rods 11 are fixedly arranged on the side of the front clamping plate 1 facing the rear clamping plate 2. The connecting rods 11 are movably inserted into the rear clamping plate 2. Through the connecting rods 11, it is convenient to accurately dock the front clamping plate 1 and the rear clamping plate 2 together and fix the copper bar plate 3.

[0030] The test joint 4 is connected to one end of the copper bar plate 3 extending out of the front clamping plate 1 and the rear clamping plate 2. When the test joint 4 is connected to the copper bar plate 3, it is convenient to test the copper bar plate 3.

[0031] Fixing members 5 for fixing the test joint 4 are arranged on the tops of the front clamping plate 1 and the rear clamping plate 2. The fixing member 5 includes a support plate 51. A through hole 52 is provided at the upper end of the support plate 51. An internally threaded tube 53 is rotatably inserted into the through hole 52. A clamping rod 54 is threadedly inserted into the internally threaded tube 53. The clamping rod 54 passes through the internally threaded tube 53 and abuts against the test joint 4. Through the through hole 52, it is convenient to assemble the internally threaded tube 53. When the internally threaded tube 53 rotates, it causes the clamping rod 54 to move and abut against the test joint 4, thereby fixing the test joint 4 on the copper bar plate 3. Therefore, it is more convenient to connect the test joint 4 and the copper bar plate 3.

[0032] A driving member 6 is movably arranged in the fixing member 5. The upper end of the driving member 6 abuts against the bottom of the test joint 4. The driving member 6 is connected to the fixing member 5 by a steel cable 7. The internally threaded tube 53 is connected to the inner wall of the through hole 52 by sleeving a torsion spring 55. When the internally threaded tube 53 rotates, it causes the torsion spring 55 to be torsionally deformed. When the steel cable 7 loses traction, the torsion spring 55 restores deformation to drive the internally threaded tube 53 to rotate and reset, and causes the clamping rod 54 to move and separate from the test joint 4, thereby facilitating the operator to disassemble the test joint 4.

[0033] The outer wall of the clamping rod 54 is provided with an external thread adapted to the internal thread tube 53. A rubber ring 56 is fixedly arranged at one end of the clamping rod 54 and the test joint 4. Two limiting rods 57 are symmetrically arranged on the outer wall of the rubber ring 56. Limiting tubes 58 opposite to the limiting rods 57 are symmetrically arranged on the outer wall of the support plate 51. The limiting rods 57 are movably inserted into the inner walls of the limiting tubes 58. When the internal thread tube 53 rotates, the rubber ring 56 and the clamping rod 54 are limited by the cooperation of the limiting rods 57 and the limiting tubes 58. Thus, when the internal thread tube 53 rotates, the clamping rod 54 is prompted to drive the rubber ring 56 to move. Furthermore, the test joint 4 is abutted through the rubber ring 56, and thus the test joint 4 is fixed on the copper busbar plate 3.

[0034] A chute 59 is arranged on the side wall of the support plate 51. The driving member 6 includes a movable plate 61 which is movably arranged in the chute 59. One end of the movable plate 61 inserted into the chute 59 is connected to the inner bottom wall of the chute 59 by a spring 62 arranged thereon. One end of the steel cable 7 is fixedly connected to the top surface of the movable plate 61. The other end of the steel cable 7 is wound around the internal thread tube 53. A contact rod 63 is fixedly arranged at the end of the movable plate 61 extending out of the chute 59. The upper end of the contact rod 63 abuts against the bottom of the test joint 4. The chute 59 facilitates the assembly of the movable plate 61. When the test joint 4 pushes the contact rod 63 and the movable plate 61 to move downward, the spring 62 is compressed and deformed. And the steel cable 7 is pulled to move synchronously by the downward movement of the movable plate 61 and the internal thread tube 53 is rotated, thus controlling the movement of the clamping rod 54.

[0035] Working principle: When using the quick connection tooling for testing the electrical performance load copper busbar of the test battery, first, the copper busbar plate 3 is installed between the front clamping plate 1 and the rear clamping plate 2. Then the test joint 4 is inserted on the copper busbar plate 3 and abuts against the driving member 6, thus pushing the driving member 6 downward and driving the fixing member 5 to move. Furthermore, the test joint 4 is fixed on the copper busbar plate 3 through the fixing member 5. Therefore, it is more convenient to test the copper busbar plate 3.

[0036] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
