[0002] In the production process of lead-acid batteries, it is necessary to accurately detect the battery's current, voltage, and other electrical signals in order to control the battery's quality and ensure that the battery performance meets the standards.

[0003] Currently, the common method for testing lead-acid battery packs is to directly connect the testing equipment to the battery electrodes. However, this connection method has many drawbacks. First, the battery manufacturing process often involves complex electrochemical reactions, and the surrounding environment may pose certain safety risks, such as potential leakage. Direct connection lacks effective safety protection structures, and in the event of an accident, it can easily threaten the personal safety of operators and may also damage the testing equipment.

[0004] Secondly, traditional connecting components are mostly fixed and non-removable. This means that if a component malfunctions or is damaged during use, the entire testing device needs to be replaced, increasing production costs and reducing testing efficiency. Furthermore, fixed connections are cumbersome to install and remove, requiring significant time and manpower, which is detrimental to rapid testing and maintenance during production. Therefore, there is an urgent need for a lead-acid battery pack testing device that improves safety, is easy to install and remove, and provides stable testing.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0020] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0021] Example 1: like Figures 1-6 As shown, this embodiment provides a lead-acid battery pack testing device. The battery pack is composed of several batteries connected in series, including a series clamp 1, a connecting structure 2, and a testing clamp 3. The series clamp 1 is used for connecting two adjacent batteries in series. The connecting structure 2 is detachably mounted on the series clamp 1 and is provided with a conductor 21 for leading out the battery signal. The testing clamp 3 is detachably clamped onto the connecting structure 2 and is connected to the battery through the conductor 21.

[0022] In this embodiment, as a specific solution, the battery is provided with electrode holes, and the series clamp 1 includes a conductive clamp body 11. The conductive clamp body 11 is provided with a conductive clamp plate 12 for insertion into the electrode holes and a connecting post 13 for detachable connection with the adapter structure 2.

[0023] In this embodiment, as a specific solution, the adapter structure 2 includes an insulator 22, the conductor 21 is disposed on the insulator 22, the insulator 22 is provided with a connection hole 23, and the connecting post 13 is detachably inserted into the connection hole 23.

[0024] In this embodiment, as a specific solution, the two adjacent batteries are connected in series by two series clamps 1, and then the negative terminal of the previous battery and the positive terminal of the next battery are respectively connected to the conductor 21 on the adapter structure 2 by two wires. In this way, the battery signal can be led out through the adapter structure 2. After the insulator 22 is inserted into the connecting post 13, the detection clamp can be clipped onto the adapter structure 2. In case of failure, the insulator 22 can be removed from the connecting post 13 to quickly disconnect the line.

[0025] In this embodiment, as a specific solution, a protruding structure 24 is provided inside the connecting hole 23; this can improve the connection strength between the insulator 22 and the connecting post 13.

[0026] In this embodiment, as a specific solution, the conductive clamp 12 includes a first clamp 121 and a second clamp 122. Both the first clamp 121 and the second clamp 122 are arc-shaped structures, and their bending directions are consistent when they are closed. In this way, the outer circumference of the two clamps when they are closed is much smaller than the inner circumference of the electrode hole. Even if the first clamp and the second clamp are not completely identical in structure during production, they can still be smoothly inserted into the electrode hole, which can reduce the resistance during insertion, thereby reducing the risk of wear on the inner wall of the electrode hole and improving the safety and service life of the battery.

[0027] In this embodiment, as a specific solution, when the conductive clamp 12 is inserted into the electrode hole, the outer wall of the first clamp 121 is in close contact with the inner wall of the electrode hole, and the edge of the second clamp 122 is in close contact with the inner wall of the electrode hole and the arc surface is away from the inner wall of the electrode hole.

[0028] In this embodiment, as a specific solution, the outer wall of the first clamping plate 121 is provided with a plurality of outer wall protrusions 123; the outer wall protrusions 123 can make the contact between the first clamping plate 121 and the electrode hole 12 more reliable.

[0029] In this embodiment, as a specific solution, the conductive clamp body 11, the conductive clamp plate 12, and the connecting post 13 are integrally formed from conductive materials.

[0030] In this embodiment, as a specific solution, the series clamp 1 is provided with an insulating protective sleeve 4; the insulating protective sleeve 4 is provided with anti-slip texture.

[0031] In another preferred embodiment, as a specific solution, the conductive clip body 11 is provided with a groove structure 14 for connecting wires. One side of the groove structure 14 is provided with a fixing slot 15 for fixing the wires. When wrapping the wires, the wires and the conductive clip body 11 are fixed with insulating tape, especially by wrapping multiple turns at the fixing slot 15, which can achieve better fixation. In specific application scenarios, it is necessary to connect one conductive clip body 1 to another conductive clip body 1 with a wire, and to connect two single batteries in series through the two conductive clip bodies; the groove structure 14 and the fixing slot 15 facilitate the installation and fixation of the wires.

[0032] Two adjacent batteries are connected in series using two series clamps 1. The two series clamps 1 are connected by wires. The negative terminal of the previous battery and the positive terminal of the next battery are respectively connected to the conductor 21 on the adapter structure 2 through the two wires. In this way, the signal of the battery can be brought out through the adapter structure 2.

[0033] The working principle of this utility model is as follows: In use, insert the insulator 22 of the adapter structure 2 into the connecting post 13 through the connecting hole 23, clamp the detection clip 3 onto the adapter structure 2, and connect the detection clip to an external voltage detection device.

[0034] The series clamp, adapter structure, and detection clamp of this utility model are all detachably connected. If any component fails or is damaged, the adapter structure can be quickly separated from the series clamp to quickly disconnect the circuit and improve detection safety. Furthermore, the detachable connection allows for quick replacement of individual components without replacing the entire detection device, which can reduce production costs and improve detection efficiency. Installation and disassembly are also more convenient, enabling rapid detection and maintenance.

[0035] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
