DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A typical implementation of the present invention is as follows: Figure 1 As shown, a new energy aluminum shell battery capacity detachable probe includes a fixing plate 1, which is fixedly connected to the cylinder on the press, so that the cylinder is used to drive the probe to move. A connecting hole is opened in the middle of the fixing plate 1, and a current probe 2 is arranged in the connecting hole. The current probe 2 is a cylindrical structure, and the diameter of the current probe 2 is smaller than the diameter of the connecting hole, so that the current probe 2 can slide in the connecting hole.

[0022] An external thread is provided on the outer surface of the top of the current probe 2, and a first nut 3 and a second nut 4 are threadedly connected to the external thread. The first nut 3 and the second nut 4 are both located above the fixing plate 1. A current connecting plate 5 is also sleeved on the outside of the current probe 2. The longitudinal cross-section of the current connecting plate 5 is L-shaped, including a bottom plate and a side plate. The bottom plate is located between the first nut 3 and the second nut 4, and the current connecting plate 5 is fixed to the current probe 2 through the first nut 3 and the second nut 4.

[0023] The bottom of the current probe 2 is provided with a current probe head. When in use, the current probe head contacts the battery cell pole, and the contact surface with the battery cell pole is made of copper plating. Figure 2 As shown, the current probe head includes an upper current probe head 6 and a lower current probe head 7. The upper current probe head 6 is fixed to the bottom end of the current probe 2, and the lower current probe head 7 is sleeved on the outside of the upper current probe head 6 and threadedly connected to the upper current probe head 6.

[0024] Specifically, the upper current probe head 6 is a cylindrical structure, the diameter of the upper current probe head 6 is larger than the diameter of the current probe 2, and an external thread is provided on the outer wall of the upper current probe head 6. The lower current probe head 7 is a cylindrical structure, which is hollow inside and has an open top, and is adapted to the upper current probe head 6. An internal thread is provided on the inner wall of the lower current probe head 7, and a threaded connection between the upper current probe head 6 and the lower current probe head 7 is realized through the external thread and the internal thread. The outer surface of the lower current probe head 7 is provided with rough texture to increase friction.

[0025] A spring 8 is also sleeved on the outside of the current probe 2. The top end of the spring 8 contacts the lower surface of the fixed plate 1, and the bottom end of the spring 8 contacts the top of the current upper probe head 6. By providing the spring 8, the current probe 2 is contracted when the probe press is pressed, thereby playing a buffering role.

[0026] A mounting hole is provided at the axis of the current probe 2, and a voltage probe 9 is arranged in the mounting hole. The length of the voltage probe 9 is greater than the length of the current probe 2. The top of the voltage probe 9 extends to the upper part of the current probe 2. A through hole 10 is provided in the middle of the bottom surface of the current probe head 7. The through hole 10 corresponds to the mounting hole. The bottom end of the voltage probe 9 passes through the through hole 10 and extends to the outside of the current probe head 7. When in use, the bottom end of the voltage probe 9 contacts the battery cell pole, and the contact surface with the battery cell pole is made of copper-plated material.

[0027] A spacer 11 is provided between the voltage probe 9 and the inner wall of the mounting hole. The spacer 11 is made of insulating material and can isolate the current probe 2 and the voltage probe 9 to prevent short circuit.

[0028] A voltage probe wiring port 12 is provided at the top of the voltage probe 9, and a current probe wiring port 13 is provided on the side panel of the current connection plate 5, wherein the voltage probe wiring port 12 is electrically connected to the voltage probe 9, and the current probe wiring port 13 is electrically connected to the current probe 2 through the current connection plate 5. The current probe wiring port 13 and the voltage probe wiring port 12 are respectively connected to the ammeter and voltmeter of the device, so as to charge the battery or test the voltage and current.

[0029] During production, the fixture with the battery cell enters the press, and the cylinder drives the fixed plate 1 and the probe to contact the battery cell pole for charging or testing voltage and current. When not in production, personnel entering the press only need to manually unscrew the current probe head 7 of the current probe 2 through the thread, clean and decontaminate it, and then manually screw it back in. This avoids the need to remove the nut and disconnect the connecting wires of the voltage and current probes, saving maintenance time.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
