It is generally composed of a conductive copper sheet and an internal threaded column. The conductive copper sheet is firmly connected to the battery cell or battery module by welding, bolting or plugging, while the internal threaded column is connected to the conductive wire by a screw. Therefore, when the screw is tightened into the internal threaded column, a force will be generated at the connection between the conductive copper sheet and the internal threaded column. In order to ensure that the quality of the terminal meets the use requirements, the terminal will be subjected to a torque test to ensure that when the screw is tightened into the internal threaded column, the connection between the conductive copper sheet and the internal threaded column will not be broken or deformed.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-5 As shown, a battery terminal torque testing tool includes a base 1, a groove 5 for accommodating a terminal thread column is formed on one side of the base 1, the top of the groove 5 extends to the top of the base 1, a slot 2 for accommodating a copper sheet 602 of a terminal 6 is formed on one side of the groove 5, a positioning hole 3 is formed on the top of the base 1, the positioning hole 3 is connected to the slot 2 and is perpendicular to the slot 2, a positioning component is arranged in the positioning hole 3, and the positioning component is used to fix the copper sheet 601 of the terminal 6 in the slot 2.
[0023] In this embodiment, if Figure 1 and Figure 2 As shown, the positioning assembly includes a positioning rod 8 inserted into the positioning hole 3, the bottom of the positioning rod 8 passes through the base 1, the top of the positioning rod 8 is fixedly connected with a positioning column 4 matching the positioning hole 3, and the outer periphery of the positioning rod 8 located in the positioning hole 3 is sleeved with an elastic member 7, the elastic member 7 is located in the positioning hole 3, and the elastic member 7 is a columnar spring;
[0024] When performing a torque test on the terminal 6, first manually apply a downward force to the positioning rod 8, so that the positioning column 4 presses down the elastic member 7 until the height of the positioning column 4 is lower than the slot 2, and then, the copper sheet 601 of the terminal 6 is inserted into the slot 2, so that the terminal thread column 601 is located in the groove 5, and the groove 5 is not in close contact with the terminal thread column 601, and then, stop applying force to the positioning rod 8, so that the positioning column 4 is reset upward under the action of the elastic member 7, and then the positioning column 4 passes through the limiting hole 603 of the copper sheet 601 to fix the copper sheet 601 in the slot 2, and then, as shown in FIG. Figure 5 As shown, the screw is screwed into the terminal thread column 602 using a wrench 11 , and the connection between the copper sheet 601 and the terminal thread column 602 is observed to see if there is any abnormality such as breakage, so as to complete the torque test operation on the terminal 6 .
[0025] Among them, Figure 3 As shown, a limiting groove 9 is provided on the circumferential surface of the positioning hole 3, the top of the limiting groove 9 is connected with the slot 2, a limiting ring 10 is arranged in the limiting groove 9, and the limiting ring 10 is fixed to the outer periphery of the positioning column 4 to resist the copper sheet of the terminal 6. When the positioning column 4 passes through the limiting hole 603 of the copper sheet 601 under the action of the elastic member 7, the limiting ring 10 will resist the copper sheet 601 from below the copper sheet 601, thereby preventing the copper sheet 601 from shaking up and down in the slot 2, and when the positioning column 4 descends, the limiting ring 10 will also descend in the limiting groove 9 to avoid interfering with the normal lifting operation of the positioning column 4.
[0026] Among them, Figure 1 As shown, the diameter of the positioning rod 8 is smaller than the inner diameter of the positioning hole 3, the top of the elastic member 7 contacts the positioning column 4 and the bottom of the elastic member 7 contacts the inner bottom of the positioning hole 3. Therefore, when the positioning rod 8 descends, it will drive the positioning column 4 to descend, thereby compressing the elastic member 7. After the force on the positioning rod 8 stops, the elastic member 7 will reset, thereby driving the positioning column 4 to rise and pass through the limiting hole 603 of the copper sheet 601.
[0027] Working principle, first, apply downward force to the positioning rod 8, so that the positioning column 4 presses down the elastic part 7 until the height of the positioning column 4 is lower than the slot 2, next, insert the copper sheet 601 of the terminal 6 into the slot 2, so that the terminal thread column 601 is located in the groove 5, and then, stop applying force to the positioning rod 8. At this time, the positioning column 4 is reset upward under the action of the elastic part 7, so that the positioning column 4 passes through the limiting hole 603 of the copper sheet 601 to fix the copper sheet 601 in the slot 2, next, align the locking screw with the terminal thread column 602, and use the wrench 11 to screw the locking screw into the terminal thread column 602, and observe whether there is any abnormality such as breakage at the connection between the copper sheet 601 and the terminal thread column 602 to complete the torque test operation of the terminal 6.
