[0036] It can be understood that CID (Current Interrupt Device) is a safety protection device in a lithium battery, which is used to prevent the battery from exploding or catching fire under abnormal conditions such as overcharging, overheating or internal short circuit. Its main function is to automatically disconnect the circuit when detecting abnormally high voltage, thereby cutting off the current to protect the battery and the user's safety. CID is usually a small metal sheet or plastic structure located in a specific position inside the battery. CID flip battery refers to the battery after CID, CID will break or bend, disconnect the circuit, cause mechanical deformation in the battery, and cause the battery to fail, but avoid more serious safety accidents such as explosion or fire.

Correspondingly, the adjusting screw passes through the adjusting hole 1121 and is fixedly connected with the second electrode connecting member 140, and the adjusting screw drives the second electrode connecting member 140 to move when the adjusting screw moves relatively.

[0040] Optionally, in combination with Figure 1 and Figure 2 As shown, one end of the adjusting screw away from the second electrode connecting member 140 is provided with an adjusting portion 131, and the adjusting portion 131 and the second electrode connecting member 140 are located on opposite sides of the second support member 112. The second support member 112 is used for connecting the adjusting screw and the second electrode connecting member 140, so that the adjusting screw can be rotated by rotating the adjusting portion 131. The user uses the adjusting portion 131, so that the setting position of the adjusting portion 131 does not hinder and affect the battery in the accommodation space.

[0041] In one embodiment, optionally, referring to Figure 1 As shown, the base 110 is parallel to the first electrode connecting member 120 and the second electrode connecting member 140, respectively. The first electrode connecting member 120 and the second electrode connecting member 140 are arranged along the first direction X, so that the base 110 does not affect the adjustment between the first electrode connecting member 120 and the second electrode connecting member 140.

[0042] Optionally, as Figure 1 As shown, the center line of the first electrode connecting member 120 and the center line of the second electrode connecting member 140 are arranged in the same line. The first electrode connecting member 120 and the second electrode connecting member 140 are arranged towards the battery, so that the first electrode connecting member 120 and the second electrode connecting member 140 can correspond to the relevant parts of the battery more accurately.

[0043] In summary, the containing space of the CID flip cell test fixture 100 is used to place the CID flip cell, the opposite ends of the CID flip cell abut against the first electrode connecting piece 120 and the second electrode connecting piece 140 respectively, the negative electrode of the CID flip cell is in contact with the first electrode connecting piece 120, the positive electrode of the CID flip cell is in contact with the second electrode connecting piece 140, the adjusting piece 130 can drive the second electrode connecting piece 140 to move, so that the second electrode connecting piece 140 is close to or away from the first electrode connecting piece 120, so as to adjust the distance between the second electrode connecting piece 140 and the first electrode connecting piece 120, optimize the physical contact effect of the CID flip cell, realize the test of the CID flip cell through the change of the distance, avoid the damage of the CID flip cell during the test, and then improve the test effect.

[0044] Embodiment 2

[0045] Reference Figure 1 and Figure 2 As shown in

[0046] Specifically, in combination with Figure 1 and Figure 2As shown, the base 110 is provided with a first support member 111 and a second support member 112, with the first support member 111 and the second support member 112 disposed opposite to each other. The first electrode connector 120 is fixedly connected to the first support member 111; one end of the adjusting member 130 is movably connected to the second support member 112. The second electrode connector 140 is connected to the end of the adjusting member 130 away from the second support member 112, so that the base 110, the first electrode connector 120, and the second electrode connector 140 together form an accommodating space. The adjusting member 130 moves the second electrode connector 140 closer to or further away from the first electrode connector 120. Correspondingly, the accommodating space is used to place the CID reversible battery, so that the opposite ends of the CID reversible battery abut against the first electrode connector 120 and the second electrode connector 140 respectively. The negative terminal of the CID reversible battery is in contact with the first electrode connector 120, and the positive terminal of the CID reversible battery is in contact with the second electrode connector 140. The adjusting member 130 can move the second electrode connector 140, so that the second electrode connector 140 is closer to or further away from the first electrode connector 120, thereby adjusting the distance between the second electrode connector 140 and the first electrode connector 120. This avoids the situation where the distance is too small and the battery is squeezed, or the distance is too large and the battery cannot be connected. It optimizes the physical contact effect of the CID reversible battery. The CID reversible battery can be tested by changing the distance, avoiding damage during the testing of the CID reversible battery.

[0047] like Figure 1 and Figure 2 As shown, the CID flip battery test fixture 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the CID flip battery test fixture 100, the second direction Y refers to the height direction of the CID flip battery test fixture 100, and the third direction Z refers to the width direction of the CID flip battery test fixture 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts of the CID flip battery test fixture 100 and should not be construed as limitations on this application.

Correspondingly, the adjusting screw passes through the adjusting hole 1121 and is fixedly connected to the second electrode connector 140. When the adjusting screw moves relative to the first electrode connector 120, it drives the second electrode connector 140 to move. For example, the adjusting hole 1121 is a threaded hole, and the adjusting screw is threadedly connected to the threaded hole. The adjusting screw drives the second electrode connector 140 to reciprocate along the length direction of the CID flip battery test fixture 100 to adjust the distance between the second electrode connector 140 and the first electrode connector 120.

[0049] Optionally, combined Figure 1 and Figure 2 As shown, an adjustment section 131 is provided at the end of the adjustment screw away from the second electrode connector 140. The adjustment section 131 and the second electrode connector 140 are located on opposite sides of the second support member 112. The second support member 112 is used to connect the adjustment screw and the second electrode connector 140, allowing the adjustment screw to be rotated by rotating the adjustment section 131. The user uses the adjustment section 131 to ensure that its position does not obstruct or affect the battery within the housing space. Exemplarily, the adjustment section 131 has a polygonal prismatic structure.

[0050] In one embodiment, alternatively, referencing Figure 1 As shown, the base 110 is parallel to the first electrode connector 120 and the second electrode connector 140 respectively. The first electrode connector 120 and the second electrode connector 140 are both arranged along the first direction X to prevent the base 110 from affecting the adjustment between the first electrode connector 120 and the second electrode connector 140.

[0051] Optionally, such as Figure 1 As shown, the center line of the first electrode connector 120 and the center line of the second electrode connector 140 are collinear. The first electrode connector 120 and the second electrode connector 140 are respectively oriented towards the battery, so that the first electrode connector 120 and the second electrode connector 140 can correspond to the relevant parts of the battery relatively accurately. Exemplarily, the axis of the first electrode connector 120 and the axis of the second electrode connector 140 are collinear.

[0052] In one embodiment, alternatively, referencing Figure 1As shown, the second electrode connector 140 moves relative to the first direction X. The moving direction of the second electrode connector 140 is parallel to the extending direction of the first electrode connector 120. The second electrode connector 140 moves relative to the length direction of the CID flip battery test fixture 100. The extending direction of the first electrode connector 120 is the length direction of the CID flip battery test fixture 100.

[0053] In one embodiment, alternatively, referencing Figure 1 As shown, the first support member 111 and the second support member 112 are located at opposite ends of the base 110. Both the first support member 111 and the second support member 112 extend towards the second direction Y, which is perpendicular to the first direction X. Both the first support member 111 and the second support member 112 extend towards the height direction of the CID flip battery test fixture 100, forming a concave frame structure with the base 110, the first support member 111, and the second support member 112. The first support member 111 connects to and supports the first electrode connector 120, and the second support member 112 connects to and supports the second electrode connector 140 and the adjusting member 130. Exemplarily, both the first support member 111 and the second support member 112 are plate-like structures.

[0054] In one embodiment, alternatively, referencing Figure 1 As shown, the second electrode connector 140 is made of insulating material and is used to isolate the negative terminal of the battery. Conversely, the first electrode connector 120 is made of conductive material to facilitate connecting the positive terminal tab of the battery to the first electrode connector 120 using a multimeter.

[0055] In one embodiment, alternatively, referencing Figure 1 As shown, the second electrode connector 140 is provided with a positioning part 141, which is a hemispherical structure. The positioning part 141 of the second electrode connector 140 is used to abut against the battery, so that the hemispherical positioning part 141 adapts to the shape and size of the battery, reduces the battery from shaking during the test, and ensures the test effect.
