[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1-4 This utility model discloses a battery terminal leakage testing device, comprising a base 1, an inverted U-shaped support plate 2 fixedly connected to the upper end of the base 1, a placement groove 3 provided in the upper surface of the base 1, in which a battery body 4 is placed, an auxiliary fixing device 5 provided on the base 1 to fix the battery body 4, a sealing testing device 6 provided on the support plate 2 to wrap the battery body 4, the sealing testing device 6 including an air compressor 7 fixed to the support plate 2, a cylinder 8 fixedly fixed vertically downward on the top wall of the support plate 2, a sealing shell 9 fixedly connected to the output end of the cylinder 8, the sealing shell 9 being open at the lower end. The base 1 has an orifice-shaped design with a sealing groove 10 on its upper surface, which is aligned vertically with the sealing shell 9. Both the sealing groove 10 and the sealing shell 9 have sealing gaskets on their contact surfaces. The upper end of the sealing shell 9 has two sets of guide rods 11 on the symmetrical cylinder 8, which extend upward through the bracket plate 2. The sealing shell 9 is connected to the air compressor 7 via a connecting pipe 12. When the battery body 4 is sealed by the sealing shell 9, the air compressor 7 injects high-pressure gas into the sealing shell 9. If the pressure inside the sealing shell 9 drops below the standard within a certain time, it can be determined that there is leakage at the terminals of the battery body 4. This method is convenient, quick, and saves manpower.

[0022] like Figure 3-4 The auxiliary fixing device 5 includes an electric push rod 13, which is vertically fixed to the upper end face of the base 1 and symmetrically placed in two sets of slots 3. A pressure plate 14 is fixed to the upper end of the electric push rod 13. The contact surface between the pressure plate 14 and the battery body 4 is made of silicone material. By pulling the pressure plate 14 with the electric push rod 13, the battery body 4 can be fixed, preventing it from shaking during testing.

[0023] like Figure 1-2A pressure sensor 15 is installed in the sealed housing 9, and a control panel 16 is installed on the bracket plate 2. The control panel 16 is connected to the signal line 17 of the pressure sensor 15. The pressure sensor 15 can monitor the gas pressure in the sealed housing 9 and transmit it to the display screen of the control panel 16 through the signal line 17, so that the pressure value can be seen.

[0024] In practical use, when detecting leakage at the terminals of the battery body 4, the battery body 4 is first placed in the placement groove 3, which is the same size as the battery body 4. Then, by controlling the electric push rod 13, the pressure plate 14 moves down. The pressure plate 14 can press and fix the upper two sides of the battery body 4 to prevent it from shaking.

[0025] Then, by controlling cylinder 8, cylinder 8 pushes the sealing shell 9 downward, and the lower end of the sealing shell 9 is inserted into the sealing groove 10. At this time, there is space between the upper end of the sealing shell 9 and the battery body 4. By working through air compressor 7, the connecting pipe 12 pressurizes the sealing shell 9. After the pressure reaches a certain value, the work stops. Pressure sensor 15 monitors the gas pressure in the sealing shell 9 and transmits it to the display screen of control panel 16. By timing, if the pressure continues to drop within the timing time, it can be determined that there is a crack at the terminal of the battery body 4, which means there is a leakage. The whole test is convenient to operate, has good test results, and does not require manual monitoring.

[0026] It should be noted that the air compressor 7 and electric push rod 13 involved in the solution need to be connected to the power supply via cables. The wiring of the electric push rod 13 can be passed through the bottom of the base 1 to connect to the power supply. The cylinder 8 needs to be equipped with an air compressor station to supply pressurized gas and controlled by a control valve. The electrical equipment needs to be equipped with a switch to control the start and stop. All of the above belong to the prior art. Those skilled in the art can clearly understand its principle and apply it in practice, so it will not be described in detail here.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
