Abstract
Description
Technical Field
[0001] This utility model belongs to the field of batteries, and specifically relates to a rechargeable battery with an integrated TYPE-C tongue. Background Technology
[0002] Currently, lithium batteries with Type-C charging ports typically have a Type-C female connector installed on their circuit board to accommodate Type-C male connectors. For example, a lithium-ion battery with publication number CN118231780A includes a polymer cell encased in a steel shell. A plastic support is mounted on the steel shell, and a PCB assembly and a Type-C female connector are mounted on the plastic support. The Type-C female connector connects to the PCB assembly. The steel shell has Type-C openings to allow connection with charging cables having Type-C male connectors, facilitating battery charging.
[0003] However, Type-C connectors are typically assembled from a metal casing and a plastic tongue, with Type-C conductive pins injection-molded onto the plastic tongue. This type of Type-C connector, with its metal casing, is relatively large and occupies significant space in lithium batteries, hindering battery design and assembly. This is especially true for AAA cylindrical lithium batteries, where it not only complicates design and assembly but also reduces the space occupied by the battery cells. For example, the sealed 1.5V lithium battery with publication number CN118336174B, due to its small diameter, cannot have its Type-C connector positioned horizontally; it must be positioned vertically. This vertical placement occupies more space in the battery, further reducing the space available for the lithium cell and resulting in a smaller cell size and consequently, a smaller battery capacity. Utility Model Content
[0004] To address the aforementioned issues, the primary objective of this invention is to provide a rechargeable battery with an integrated Type-C connector. The Type-C connector is fabricated directly on the battery's circuit board, eliminating the need for a Type-C female connector. This simplifies the Type-C interface structure, thereby facilitating battery design and assembly and reducing costs.
[0005] Another objective of this invention is to provide a rechargeable battery with an integrated TYPE-C tongue, whose TYPE-C interface is small in size, which can reduce the space occupied, thereby increasing the size of the battery cell and improving the battery capacity.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] This utility model provides a rechargeable battery with an integrated TYPE-C tab, comprising:
[0008] case;
[0009] The battery cell is installed inside the housing;
[0010] A charge / discharge control module includes a main body and a circuit board. The main body is mounted on the housing, and the circuit board is fixed to the main body. One end of the circuit board has a TYPE-C tongue integrally formed therewith. The main body has a TYPE-C socket, and the TYPE-C tongue is located inside the TYPE-C socket.
[0011] Furthermore, the circuit board is a PCB board, and the TYPE-C tongue is formed by printing a TYPE-C interface circuit at one end of the PCB board, thereby enabling the TYPE-C tongue to form an integrated structure with the circuit board.
[0012] Furthermore, the main body has a mounting groove, and the inner wall of the TYPE-C connector is provided with a snap-fit hole communicating with the mounting groove. The circuit board passes through the snap-fit hole, and the end of the circuit board facing away from the TYPE-C tongue is located in the mounting groove. Through the above structural design, the circuit board can be fixed to the main body.
[0013] Furthermore, the housing has a mounting cavity and a mounting position, the mounting position being located above the mounting cavity, the battery cell being disposed within the mounting cavity, the main body being disposed on the mounting position, and the housing having an opening corresponding to the position of the TYPE-C connector, thereby facilitating the insertion of the TYPE-C male connector through the housing into the TYPE-C connector.
[0014] Furthermore, the main body extends downwards with two opposing connecting arms, each connecting arm having a positioning buckle, and the side wall of the mounting position having a positioning hole, the positioning buckle being engaged in the positioning hole.
[0015] Furthermore, the charging and discharging control module also includes a positive terminal and a conductive spring. The housing is made of a conductive metal material, and the bottom of the housing has a negative terminal. The positive terminal passes through the main body and is connected to the circuit board. The battery cell includes a battery cell body, on which a positive terminal tab and a negative terminal tab are provided. The positive terminal tab is electrically connected to the circuit board through the conductive spring, and the negative terminal tab is electrically connected to the circuit board through the housing.
[0016] Furthermore, the negative electrode tab is an "L"-shaped spring piece, with one side of the spring piece fitting against the inner wall of the housing and the other side fitting against the bottom of the battery cell body.
[0017] Furthermore, the circuit board is also provided with an "L"-shaped conductive connecting piece, one side of which is attached to the inner wall of the housing, and the other side is attached to the bottom of the circuit board.
[0018] The advantage of this invention compared to existing technologies is that:
[0019] First, by designing an integrated TYPE-C tongue at one end of the circuit board, which works in conjunction with the TYPE-C connector on the main body, a TYPE-C interface can be formed, eliminating the need for a TYPE-C female connector. This simplifies the structure of the TYPE-C interface, thereby facilitating battery design and assembly and reducing costs.
[0020] Secondly, compared to the traditional TYPE-C female connector, the TYPE-C tongue of this application occupies a smaller volume, which can reduce the space occupied by the TYPE-C interface. Under the premise of keeping the shell size unchanged, the size of the battery cell can be increased and the battery capacity can be improved. Attached Figure Description
