Description

[0001] The present invention claims priority to Chinese Patent Application No. 202021561663.8, filed on July 31, 2020, and entitled “STORAGE BATTERY SCREW TERMINAL”, which is incorporated herein by reference in its entirety. TECHNICAL FIELD [0002] The present invention relates to a technical field of connecting automotive electrical devices and, in particular, to a quick-replaceable storage battery screw connection terminal. FUNDAMENTALS [0003] The automotive storage battery screw terminal is an indispensable component for connecting the automotive wiring harness to the storage battery and is required for all automobiles. The important function of the automotive storage battery screw terminal is to achieve the connection between the vehicle's entire wiring harness and the storage battery, so that the electrical functions of the entire vehicle can operate normally. It is necessary to install the storage battery screw reliably, safely, and conveniently. The existing storage battery screw terminal is first placed into a sleeve on a storage battery post and then tightened and secured with a screw, or when the storage battery screw terminal needs to be disassembled to cut off the power supply in case of maintenance or transport of the entire vehicle, the operation must be completed with a tool, which is very inconvenient and poses a safety risk in direct line work during maintenance. SUMMARY [0004] Addressing the shortcomings of the prior art, the problem to be solved here is to provide a storage battery screw terminal that is convenient and can be disassembled and assembled without tools, so as to overcome the technical defect caused by the fact that the existing storage battery screw terminal needs to be operated by a screw tightening tool during disassembly and assembly. [0005] The present invention adopts the following technical solution to solve the technical problem: a storage battery screw terminal is provided, including: a terminal including a storage battery terminal connection unit, compressible units being provided on two sides of one opening end of the storage battery terminal connection unit and a cable connection unit being provided on the other opening end of the storage battery terminal connection unit; and a gasket including a crimping unit and two rotary units provided in the crimping unit (201), wherein the compressible unit is rotatably connected to the rotary unit and the rotary unit is provided with a locking unit. The storage battery terminal connection unit is connected to a storage battery post, having a conical shape compatible with that of the storage battery post and a size compatible with that of the storage battery post and can be combined and connected to the anode and cathode of the storage battery as required. [0006] Another solution of the present invention is that the gasket is externally provided with a protective cover adapted to the pressing unit, and the protective cover is fixedly connected to the gasket by tightening. The protective cover includes a main unit and a fastening unit, and the main unit of the protective cover is rectangular in shape, or it can be of any circular or polygonal shape, provided it corresponds to the pressing unit. The function of the fastening unit is to hold the gasket without loosening or falling off. There may be a fastening unit at the top and bottom, respectively, or the number of fastening units may also be three, four, five, etc. [0007] An additional solution of the present invention is that when the overlapping part is rotated upwards from the terminal, the locking unit locks the terminal with a storage battery post by compressing the compressible unit. During the disassembly of the storage battery screw terminal, the locking unit can be released from the compressible unit once the protective cover is manually lifted, thus performing the disassembly between the storage battery screw terminal and the storage battery post, which is very convenient and quick. The storage battery terminal connection unit is connected to the storage battery post and matches its shape. [0008] Another solution of the present invention is that a stop unit is provided outside the compressible unit and, when the overlay is rotated, the rotating unit abuts the stop unit to form a limiting fit between the stop unit and the rotating unit. When the protective cover and the overlay are rotated to a certain point, the rotation of the overlay is stopped. At the same time, the storage battery terminal connection unit is connected to the storage battery terminal. [0009] An additional solution of the present invention is that the protective cover is made of a hard flame-retardant material. Different types of materials, such as PBT-GF30, PA6, PA66, PC/ABS, etc., are selected for the protective cover, depending on the strength, degrees of temperature resistance and material characteristics, and any material must meet the requirements of flame retardancy and strength.
