Description

Lead-acid batteries for starting with side-mounted terminals Technical Field

[0001] The present invention relates to the technical field of lead-acid batteries, in particular to a side-terminal starting lead-acid battery. Background Art

[0002] The terminal side-mounted lead-acid starting battery refers to a battery with the terminals originally installed on the top moved to the side to save space in the vehicle.

[0003] Existing terminals are often covered with rubber sleeves for protection after production. However, when they are connected to the wires through bolts, the connection is often directly exposed to the outside. Since the bolts are conductors, there are certain safety hazards when they are exposed to the outside. Bolts exposed to the outside for a long time are prone to dust or rust, which increases obstacles to subsequent disassembly.

[0004] Summary of the Invention

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Existing terminals are often covered with rubber sleeves for protection after production. However, when they are connected to the wires through bolts, the connection is often directly exposed to the outside. Since the bolts are conductors, there are certain safety hazards when they are exposed to the outside. Bolts exposed to the outside for a long time are prone to dust or rust, which increases obstacles to subsequent disassembly.

[0026] In response to the above technical problems, the present application provides a lead-acid battery for starting with a side-mounted terminal. FIG1 shows a schematic diagram of the overall structure of a lead-acid battery for starting with a side-mounted terminal.

[0027] In FIG1 , the side-terminal starting lead-acid battery includes a body 100 and two sets of connection terminals 200 . The two sets of connection terminals 200 are symmetrically arranged on any two opposite end surfaces of the body 100 .

[0028] FIG2 shows a schematic cross-sectional structure diagram of the cavity; in FIG2 , along the extension direction of the connection terminal 200, the following are connected in sequence:

[0029] An extension sleeve 310 is concentrically disposed with the mounting hole of the terminal block 200. A cavity 311 is defined within the extension sleeve 310. A shaft 312 is rotatably connected within the cavity 311. A torsion spring 313 is connected to the shaft 312. The other end of the torsion spring 313 is connected to the inner wall of the cavity 311.

[0030] A sealing cover 320 is placed on the end surface of the extension sleeve 310 to seal it, and the other end of the rotating shaft 312 is connected to the sealing cover 320;

[0031] The sealing cover 320 is driven by an external force to rotate around the rotating shaft 312 to open the extension sleeve 310, and is reset by the elastic force of the torsion spring 313 after the external force is removed.

[0032] In specific use, the sealing cover 320 is driven by the elastic force of the torsion spring 313 to form a continuous closure for the extension sleeve 310. During installation, an external force is applied to the sealing cover 320 and it is driven to rotate around the rotating shaft 312. At this time, the extension sleeve 310 is opened, and the torsion spring 313 is deformed, and the terminal connection can be performed. After the connection is completed, the external force applied to the sealing cover 320 is removed, and the elastic force of the torsion spring 313 can drive the sealing cover 320 to reset, and the terminal connection is blocked again. Through this structure, the connection can be automatically and continuously protected after the terminal is installed, avoiding the connection from being exposed to the outside, reducing safety hazards, and extending the service life of the installation parts, providing convenience for subsequent disassembly and maintenance.

[0033] FIG3 shows a schematic cross-sectional view of the extension sleeve 310 ; FIG4 shows a schematic view of the state structure of FIG3 ; in FIG3 and FIG4 , a notch 314 is provided on the extension sleeve 310 , and the size of the notch 314 matches the size of the wire.

[0034] In specific use, after the terminal is installed, the wire can be placed in the recess 314 and led out, as shown in FIG4 . This design can complete the placement of the wire while ensuring the sealing of the protection.

[0035] Referring to Figures 3 and 4; a sliding cavity 315 is opened in the extension sleeve 310, and a clamping block 316 is slidably connected in the sliding cavity 315. One end of the clamping block 316 passes through the sliding cavity 315 and extends into the recess 314. A spring 317 is provided between the inner wall of the sliding cavity 315 and the clamping block 316. The spring 317 is in a compressed state and drives the clamping block 316 to clamp the wire.

[0036] During use, an external force is applied to drive the clamp 316 into the sliding cavity 315, and then the wire is placed in the recess 314. When the external force is removed, the clamp 316 is reset and the wire is clamped. Through this structure, it can be applied to wires of different sizes to improve the applicability of the device.

[0037] 3 and 4 , one end of the clamping block 316 away from the notch 314 is connected to a pull rope 318 , and the other end of the pull rope 318 is connected to the rotating shaft 312 ;

[0038] The clamping block 316 is driven by the rotating shaft 312 to release the sealing of the notch 314 when the extension sleeve 310 is opened, and is reset to clamp the wire when the extension sleeve 310 is closed.

[0039] During use, when the sealing cover 320 rotates around the rotating shaft 312, the rotating shaft 312 rotates synchronously and wraps the pull rope 318 around its surface, thereby pulling the clamping block 316 into the sliding cavity 315 to release the closure of the recess 314. At this time, the extension sleeve 310 and the recess 314 are opened synchronously. When the sealing cover 320 is reset, the rotating shaft 312 rotates in the opposite direction and releases the traction on the clamping block 316. At this time, the clamping block 316 is driven to reset by the compression force of the spring 317. At this time, the extension sleeve 310 and the recess 314 are closed synchronously. Through this structure, the synchronous opening or closing of the extension sleeve 310 and the recess 314 can be achieved, thereby improving the integrity of the device.

[0040] A rubber pad is provided on the end surface of the clamping block 316 that is released from the wire.

[0041] When the clamping block 316 squeezes the wire, the rubber pad is deformed by the squeezing, which protects the wire on one hand, and fills the gap between the notch 314 and the wire on the other hand, thereby improving the sealing effect.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
