[0002] Currently, I²C or SMBUS communication methods are commonly used to connect batteries with integrated fuel gauges to a host computer, allowing the computer to read the fuel level information recorded in the fuel gauge. To achieve this communication connection between the battery and the host computer, dedicated pre-fabricated fixtures are typically used. However, the specific locations of the positive and negative terminals and communication contacts on the battery output port often differ between different battery models. Since custom-made fixtures are time-consuming and costly, to improve the efficiency of battery fuel level detection and reduce costs, technicians generally use pre-fabricated fixtures on the battery output port (e.g.,...) Figure 1 The + and - symbols shown) and communication contacts (such as Figure 1 Soldering wires onto the SCL and SDA contacts shown in the diagram and connecting these wires to the host computer is somewhat inconvenient, and soldering wires onto the battery will also affect the appearance of the battery.

[0009] In one of the technical solutions, the outer wall of the clamp is fixed with a plurality of screws, and the terminal is sleeved in a corresponding screw and can rotate around the central axis of the corresponding screw.

[0010] In one of the technical solutions, the test fixture further includes multiple wires, which are connected one-to-one with multiple terminals. One end of each wire is held by the head of the screw and the terminal, and the other end of the wire is used to connect to an external host computer.

[0011] In one of the technical solutions, the elastic element is a torsion spring.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 2 This utility model provides a battery testing fixture, which mainly includes a holder 1 and multiple terminals 2 arranged at intervals. Since the host computer needs to connect to the battery's positive and negative terminals and two communication contacts to establish a communication connection, the number of terminals 2 is preferably at least four. Two terminals 2 are used to connect to the battery's positive and negative terminals; specifically, the first terminal 2 is connected to the positive terminal of the battery's output port, the second terminal 2 is connected to the negative terminal of the battery's output port, the third terminal 2 is preferably connected to the SCL contact of the battery's output port, and the fourth terminal 2 is preferably connected to the SDA contact of the battery's output port. The ends of all four terminals 2 furthest from the battery are connected to the host computer to achieve a communication connection between the battery and the host computer, enabling the host computer to obtain data information from the battery. This data information includes, but is not limited to, battery level information, temperature information, voltage information, or current information. Preferably, the testing fixture in this embodiment also includes multiple wires 3, which are connected one-to-one with the multiple terminals 2. Specifically, before use, the battery test fixture of this solution allows multiple terminals 2 to be pre-connected to the host computer via wires 3. When communication testing of a battery is required, the spacing between the terminals 2 can be pre-adjusted according to the specifications of the battery to be tested. Then, the battery is placed in the holder 1, and each terminal 2 is aligned with the corresponding contact on the battery output port. At this point, the battery and the host computer will establish a communication connection, and the host computer can acquire the battery data. During the battery testing process, the battery remains firmly clamped by the holder 1, ensuring a reliable communication connection between the battery and the host computer, thus improving the reliability of the battery testing operation. Using this test fixture, there is no need for a dedicated fixture or repeated soldering of wires to the output ports of each battery. This solution only requires adjusting the positions of multiple terminals 2 to a suitable location to quickly meet the communication testing needs of batteries with various output ports. This test fixture has the advantages of compatibility with multiple battery specifications and ease of operation, which helps improve the efficiency of battery communication testing and reduce testing costs.

[0024] Please refer to it again. Figure 2 The clamp 1 specifically includes a base 11, a clamping plate 12, and an elastic element 13. The base 11 and the clamping plate 12 are rotatably connected at a rotating shaft 121. The elastic element 13 is preferably a low-cost torsion spring. The elastic element 13 is sleeved in the rotating shaft 121 and connected to the base 11 and the clamping plate 12 respectively. The clamping plate 12 has a rotational tendency to automatically push against the base 11 under the elastic force of the elastic element 13. A clamping space 14 is formed between the base 11 and the clamping plate 12. The end of the clamping plate 12 away from the clamping space 14 is provided with a bent pressing part 122. The operator can drive the clamping plate 12 to rotate and open the clamping space 14 by pressing the pressing part 122. At this time, the battery can be placed in the clamping space 14. After releasing the pressing part 122, the clamping plate 12 and the base 11 together clamp the battery under the elastic force of the elastic element 13, so that the battery can be in a relatively stable state. The aforementioned multiple terminals 2 can be designed to be movably connected to the base 11 or to be movably connected to the clamping plate 12. However, the ends of the multiple terminals 2 need to extend into the clamping space 14 so that the multiple terminals 2 can be interconnected with the output port of the battery located in the clamping space 14.

[0025] Please refer to it again. Figure 2In this embodiment, the multiple terminals 2 are preferably movably connected to the outer surface of the clamping plate 12. The movable connection can be a sliding connection or a rotating connection, both of which can achieve the purpose of adjustable spacing between adjacent terminals 2. In addition, the clamping plate 12 is preferably a transparent structure, allowing operators to more intuitively place the multiple terminals 2 against the corresponding positions of the battery output port through the transparent clamping plate 12, reducing the difficulty of operation for operators and thus improving the efficiency of battery testing.

[0026] Please refer to it again. Figure 2 Multiple screws 15 are fixed to the outer wall of the clamping plate 12. The terminal 2 is sleeved on the outer wall of a corresponding screw 15 and can rotate around the central axis of the corresponding screw 15. This design achieves a rotatable connection between the terminal 2 and the base 11. Using screws 15 to enable the rotation of the terminal 2 has the advantage of low cost. Furthermore, the end of the aforementioned wire 3 furthest from the host computer is designed to be clamped by the head of the screw 15 and the terminal 2, ensuring a reliable connection between the wire 3 and the corresponding terminal 2, thus improving the reliability of the connection between the wire 3 and the battery and the host computer.

These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
