Description

Technical Field

[0001] This utility model relates to the field of batteries, specifically a cylindrical battery with a quick-connect terminal structure. Background Technology

[0002] Cylindrical batteries are a type of battery with high capacity, long cycle life, and a wide operating temperature range. With the continuous development of the new energy field, cylindrical batteries are being used more and more widely due to their advantages such as high energy density.

[0003] However, the existing technology has the following drawbacks: To extend battery life and enable cyclic use, existing batteries have external terminals for easy charging. However, existing cylindrical batteries are fixedly connected to the terminals and cannot be disassembled. If either the terminal or the battery is damaged, the entire battery must be replaced, resulting in wasted resources. Furthermore, the structure is complex and installation is difficult. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical battery with a quick-connect terminal structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical battery with a quick-connect terminal structure, comprising a cylindrical battery body, a fixing strip, and a terminal mechanism. A connecting sleeve is fixedly installed in the middle of the top of the battery body. Four through slots are evenly opened in the middle of the connecting sleeve. The terminal mechanism includes a mounting base. A connecting post is provided at the bottom of the mounting base and is inserted into the inside of the connecting sleeve. Four third slots are evenly opened in the middle of the connecting post and are corresponding to the through slots. The fixing strip is divided into a connecting area and a reinforcing area. Four third blocks are evenly provided in the middle of one side of the connecting area. The connecting area is wrapped around the outside of the connecting sleeve. The third blocks pass through the through slots and engage with the inside of the third slots.

[0006] The above technical solution features a separate design for the battery body and terminals, which simplifies the connection structure, facilitates quick installation, makes it easy to replace parts, and extends the service life.

[0007] The battery body has an installation groove in the middle of its top, and an annular plate is fixedly installed on the top of the installation groove. Four second slots are evenly provided on the annular plate, and four second blocks are evenly provided around the bottom of the connecting post. The second blocks are engaged and installed inside the second slots, and the bottom of the connecting post is in close contact with the top of the annular plate.

[0008] In this technical solution, the second card block is inserted into the second card slot, ensuring a tight connection and preventing it from falling off.

[0009] A connector is provided in the middle of the bottom inner wall of the mounting groove. A plug is fixedly installed on the top of the mounting base, and two inserts are symmetrically arranged inside the plug. The bottom of the insert passes through the mounting base and is fixedly connected to the wire. A through hole is opened in the middle of the connecting post, and the wire at the bottom of the insert passes through the through hole and is fixedly connected to the connector.

[0010] The above technical solution connects the terminal mechanism to the battery body via wires, facilitating electrical connection of the cylindrical battery through the terminals and making charging convenient.

[0011] The inner walls at both ends of the third slot are provided with grooves in the middle. A spring is fixedly installed on the inner wall of the groove. A first locking block is fixedly installed on the side of the spring away from the groove. A fourth slot is provided at the middle of both ends of the third locking block. The first locking block is engaged and installed inside the fourth slot.

[0012] Using the above technical solution, the spring has good elasticity and can extend and retract inside the grooves at both ends of the third slot, carrying the first locking block.

[0013] The first card block has beveled edges on both sides, the length of the spring is less than the depth of the groove, the shape of the fourth card slot is the same as the shape of the first card block, and the size of the fourth card slot is larger than the size of the first card block.

[0014] The above technical solution involves cutting the first card block at an angle on both sides, which facilitates squeezing the first card block into the groove when the front end of the connecting column is inserted into the middle section of the third card slot.

[0015] The inner wall of the connecting sleeve is evenly provided with four first slots, which are staggered with the through slots. The side wall of the connecting column is evenly provided with four protruding strips, which are corresponding to the first slots and are engaged and installed inside the first slots.

[0016] The above technical solution, in which the protruding strip and the first slot are positioned to provide positioning, ensures the quick installation of the connecting column and the connecting sleeve.

[0017] An adhesive strip is attached to the side of the reinforcement area near the third card block. The reinforcement area is wrapped around the outside of the connection area and the two are bonded together by the adhesive strip.

[0018] With the above technical solution, the reinforcement area continues to be wrapped around the outside of the connecting sleeve, which strengthens the connection between the connecting area and the connecting sleeve and the connecting column.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a separate terminal mechanism and cylindrical battery design, which facilitates repair and disassembly for replacement, effectively extending the service life of the cylindrical battery. The terminal mechanism is snapped into one end of the cylindrical battery and reinforced with a fixing strip on the outside. The connection structure is simple, easy to operate, and allows for quick installation. Attached Figure Description
