Description

Technical Field

[0001] The utility model belongs to the technical field of battery wiring harnesses, and in particular relates to a battery wiring harness with a quick-fastening connector. Background Art

[0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery. After discharge, the internal active substances can be regenerated by charging - storing electrical energy as chemical energy; when it is necessary to discharge, the chemical energy is converted into electrical energy again. Usually, when the automotive battery harness is connected to the battery, the fastening connection function is achieved by tightening the nut. When connecting or disconnecting the battery, a special wrench must be used for operation. It is not possible to quickly achieve tool-free disassembly, and the protective cover at the joint also lacks a fixed structure, which leads to the problem of loss during use, and it is also prone to oxidation and rust.

[0003] To this end, a battery wiring harness with a quick-fastening connector with a bulletin number of "CN218160874U" is provided, comprising a wire body and a fixing ring; the wire body: both ends are fixed with mounting rings, the bottom end of the outer side surface of the mounting ring is provided with a fixing plate, the fixing ring is sleeved on the outer side surfaces of the two fixing plates, the rear side surface of the fixing ring is provided with a shell, the interior of the shell is slidably connected with a sliding rod, the outer end of the sliding rod is fixed with a side plate, the inner side surface of the side plate is installed with a locking block, the outer side of the wire body is sleeved with a fixing component, and the front side surface of the fixing ring is provided with a protective component; wherein: it also includes a gear lever, the gear lever is rotatably connected to the front end of the side surface of the fixing ring, the mounting ring is installed to the outside of the battery pole, and the fixing ring is clamped on the outside of the fixing plate at the bottom end of the mounting ring, so that it is easy to disassemble and assemble, firmly fixed, and highly practical.

[0004] However, for the above-mentioned battery wiring harness with quick-tightening connector, although the fixing ring is clamped on the outer side of the fixing plate at the bottom end of the mounting ring, and the sliding rod inserts the locking block on the inner side of the side plate into the locking groove in the middle of the fixing plate, thereby increasing the firmness of the mounting ring and solving the problem of using tools for disassembly and assembly, the following obvious defects still exist during use: the battery pole is fixed by the clamping structure on the fixing ring, and this fixing method cannot continuously lock the battery pole on the battery pole, which can easily cause the fixing ring to slip and loosen on the battery pole when the battery wiring harness is connected to the battery, thereby failing to ensure the stability and firmness of the fixing ring on the battery pole.
