Technical Field
[0001] The utility model relates to the technical field of batteries, in particular to an anti-loosening battery terminal sleeve. Background Art
[0002] Terminals are components that connect batteries to external conductors. In electrical engineering, terminals mostly refer to wiring terminals, also called terminal blocks. They are classified into single-hole, double-hole, sockets, hooks, etc., and are made of materials such as silver-plated copper, zinc-plated copper, copper, aluminum, and iron. Their main function is to transmit electrical signals or conduct electricity. During operation, the protective layer of the connecting wire needs to be peeled off, inserted into the connecting hole of the terminal, and contacted with the contact pins installed in the hole.
[0003] Chinese patent CN215266593U discloses a lead-acid battery terminal, comprising a lead sleeve and a copper terminal, the lead sleeve and the copper terminal being fixedly connected by a connector, the copper terminal being provided with a threaded hole, and the outer surface of the lead sleeve being provided with a step. The hourglass-shaped through-hole structure within the lead sleeve of the utility model facilitates insertion and fixation of the positive and negative lead terminals of the battery within the lead sleeve, while the larger top opening effectively increases the degree of lead soldering and improves the terminal welding quality. The stepped design on the outside of the lead sleeve increases the path for the acid inside the battery to climb upward, reducing the risk of battery failure caused by acid creeping or leakage. Furthermore, the groove on the side of the connector increases the bonding strength between the plastic material of the battery cover and the terminal. When the terminal is in use, the load connection bolt can be screwed into the threaded hole of the copper terminal, preventing it from loosening.
[0004] When using this device, the stripped end of the connecting wire must first be inserted into the connecting hole of the terminal, and then the connecting wire is fixed by tightening bolts. However, the connecting wire is easily pulled by external force during long-term use, causing the core wire of the connecting wire to break and fall off. Utility Model Content
[0005] To address the above problem, a battery terminal sleeve with an anti-loosening function is provided. The connecting wire is wound around the outside of the sleeve using a wire winding roller. When the connecting wire is pulled by external force, the wire winding roller drives the L-shaped slide and the slider to move, and the slider squeezes the second spring when moving. The second spring is used to relieve the pulling force on the connecting wire and effectively prevent the connecting wire from being pulled out of the wire hole due to force.

[0027] The connecting wire is wound around the outside of the winding roller 5. When the connecting wire is pulled by external force, the winding roller 5 will drive the L-shaped slide 4 and the slider 16 to move, and the slider 16 will squeeze the second spring 18 when moving. The second spring 18 is used to relieve the pulling force on the connecting wire and effectively prevent the connecting wire from being pulled out of the wire hole 9 due to the force.
[0028] like Figure 2 and Figure 3 As shown, the side wall of the L-shaped slide 4 is provided with a support block 12, the top of the support block 12 is provided with a telescopic rod 13, the top of the telescopic rod 13 is provided with a cross bar 8, the bottom of the cross bar 8 is provided with several connecting parts 11, and the bottom of the connecting part 11 is provided with an arc-shaped pressure plate 6.
[0029] The crossbar 8 can be used to drive the connecting piece 11 and the arc-shaped pressing plate 6 to move upward, so as to facilitate the winding of the connecting line on the outside of the winding roller 5.
[0030] like Figure 2 and Figure 3 As shown, a first spring 14 is sleeved on the outside of the telescopic rod 13 , one end of the first spring 14 is connected to the top of the support block 12 , and the other end of the first spring 14 is connected to the bottom of the cross bar 8 .

[0042] Working principle: first rotate the pull block 15 ninety degrees, and then pull it upward so that the pull block 15 passes between the two L-shaped slides 4, and at the same time drives the connecting piece 11 and the arc-shaped pressure plate 6 to move upward. At this time, reverse the pull block 15 ninety degrees, and the pull block 15 will be stuck in the groove at the top of the two L-shaped slides 4, so that it is convenient to wind the connecting wire around the outside of the winding roller 5. When the winding is completed, the terminal of the connecting wire is connected to the terminal through the wire hole 9. After the connection is completed, rotate the screw 10 to drive the arc-shaped pressure block 19 to squeeze the connecting wire to prevent the terminal of the connecting wire from being stuck in the long When the connecting wire is loosened during operation, the pull block 15 is pulled upward to disengage it from the groove. At this time, the card block is rotated ninety degrees, and the pull block 15 will slide down from between the two L-shaped slides 4. The telescopic rod 13 and the first spring 14 can be used to squeeze the wound connecting wire. When the connecting wire is pulled by external force, the winding roller 5 will drive the L-shaped slide 4 and the slider 16 to move, and the slider 16 will squeeze the second spring 18 when moving. The second spring 18 is used to relieve the pulling force on the connecting wire and effectively prevent the connecting wire from being pulled out of the wire hole 9 under force.
