Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, specifically to a storage battery terminal connection structure. Background Technology

[0002] Lead-acid batteries mainly consist of electrolyte, battery case, and electrode arrays. The electrolyte is a sulfuric acid solution. The electrode arrays primarily consist of positive plates, negative plates, and separators. The separators mainly serve to store the electrolyte, act as a gas channel for oxygen recombination, prevent the shedding of active materials, and prevent short circuits between the positive and negative electrodes. The electrode arrays have busbars and lead bridges that connect all the electrode arrays in series. Terminal posts are connected to the electrode arrays at both ends, passing through terminal holes in the battery case cover. These terminal posts are typically connected to terminals for connecting external power lines.

[0003] A search revealed that application number CN209607832U discloses "a battery terminal block," which includes a terminal post with a connection hole on its top surface and a slot on the side wall of the connection hole. The battery terminal block also includes a connector, which comprises a connecting segment and an operating segment. The end of the connecting segment extends into the connection hole and is provided with a locking block that engages with the slot. This utility model of a battery terminal block replaces the commonly used threaded connection in the prior art by providing a connection hole on the top surface of the terminal post, a slot on the side wall of the connection hole, and a connector comprising a connecting segment and an operating segment. The connector end extends into the connection hole and is provided with a locking block that engages with the slot. The connector and the terminal post are connected by a snap-fit ​​connection, avoiding problems such as insufficient thread, loose terminal welding leading to loose screws, and excessively large screw holes rendering the entire battery pack unusable.

[0004] Therefore, it is necessary to propose a solution for battery devices to address the aforementioned problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution:

[0026] A battery terminal connection structure includes a base plate 1, a terminal post 2 mounted on the top of the base plate 1, a threaded groove 3 formed in the terminal post 2, a recessed hole 4 mounted below the threaded groove 3, a vertical groove 5 formed on the surface of the threaded groove 3, a first fixing mechanism 6 installed inside the vertical groove 5, a second fixing mechanism 8 installed in a first rotating column 61 of the first fixing mechanism 6, and a protective mechanism 9 installed in a second rotating column 82 of the second fixing mechanism 8.

[0027] In the specific implementation process, such as Figure 5 The first fixing mechanism 6 shown includes a first rotating column 61 installed in the terminal block 2. The surface of the first rotating column 61 is provided with a threaded groove 62, and a rotating handle 63 is installed above the threaded groove 62.

[0028] It should be noted that the first rotating post 61 installed in the terminal block 2 has a threaded groove 62 on its surface. A rotating handle 63 is installed above the threaded groove 62. After the wire end is connected, the operator can rotate the rotating handle 63 to thread the first rotating post 61 through the threaded groove 62 to the threaded groove 3 in the terminal block 2, ensuring a secure connection.

[0029] In the specific implementation process, such as Figure 5 The second fixing mechanism 8 shown includes a bolt 81 installed in the movable hole 7, a second rotating column 82 installed below the bolt 81, and a rotating block 83 installed below the second rotating column 82.

[0030] It should be noted that the bolt 81 installed in the movable hole 7 has a second rotating column 82 installed below it, and a rotating block 83 installed below the second rotating column 82. After the first fixing mechanism 6 is fixed, the second rotating column 82 installed in the movable hole 7 of the first rotating column 61 will move downward with the threaded connection, while the rotating block 83 moves downward in the vertical groove 5 until it reaches the concave hole 4. Then, by rotating the bolt 81, the rotating block 83 is fixed in the concave hole 4, which can effectively perform lateral and longitudinal positioning to ensure the fixation of the wire end.

[0031] In the specific implementation process, such as Figure 4 The protective mechanism 9 shown includes a spring 91 installed inside the second rotating column 82, a pressing block 92 installed on the other side of the spring 91, a balance block 93 installed below the pressing block 92, fixing blocks 94 installed on both sides of the balance block 93, and a squeezing block 95 installed below the balance block 93.

[0032] It should be noted that the spring 91 installed inside the second rotating column 82 has a pressing block 92 installed on the other side, a balancing block 93 installed below the pressing block 92, fixing blocks 94 installed on both sides of the balancing block 93, and a pressing block 95 installed below the balancing block 93. When the second fixing mechanism 8 is fixed, the protective mechanism 9 installed inside the second rotating column 82 will press the pressing block 92, the balancing block 93, and the pressing block 95 downward under the action of the spring 91 and the fixing block 94. This fixes the wire end without damaging it, thus preventing the fixing of the device from causing damage to the wire end.

[0033] In the specific implementation process, such as Figure 1 The threaded protrusion 62 shown is threadedly connected to the threaded groove 3.

[0034] It should be noted that the threaded protrusion 62 is threadedly connected to the threaded groove 3.

[0035] In the specific implementation process, such as Figure 1 The extrusion block 95 shown is made of rubber.

[0036] It should be noted that the material of the extrusion block 95 is rubber, which is known for its wear resistance, as well as high strength and good elasticity.

[0037] In the specific implementation process, such as Figure 5 The first rotating column 61 shown has a moving hole 7 inside.

[0038] It should be noted that a movable hole 7 is provided inside the first rotating column 61.

[0039] The working principle of this embodiment is as follows: In specific use, after the wire end is connected, the operator rotates the rotating handle 63 to connect the first rotating column 61 to the threaded groove 3 in the terminal post 2 through the threaded protrusion 62, ensuring a firm connection. After the first fixing mechanism 6 is fixed, the second rotating column 82 installed in the moving hole 7 in the first rotating column 61 will move downward with the threaded connection, while the rotating block 83 moves downward in the vertical groove 5 until it reaches the concave hole 4. Then, by rotating the bolt 81, the rotating block 83 is fixed in the concave hole 4, which can effectively perform lateral and longitudinal positioning to ensure the wire end is fixed. After the second fixing mechanism 8 is fixed, the protective mechanism 9 installed in the second rotating column 82 will press the lower pressure block 92, the balance block 93, and the squeezing block 95 downward under the action of the spring 91 and the fixing block 94. This ensures that the wire end is fixed without damaging it, thus preventing the fixing of the device from causing damage to the wire end.

[0040] The remaining parts not described in this utility model are existing or known technologies.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
