Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 3 This utility model provides a solderless magnetic battery, including a shell 1. Inside the shell 1, from one end to the other, a battery cell 2, a base 3, a PCB board 5, and a magnetic connector 6 are arranged sequentially. The battery cell 2 has positive and negative leads 21. The PCB board 5 is provided with positive and negative pads. Solderless terminals 4 are electrically connected through the positive and negative pads. The solderless terminals 4 are inserted into the positive and negative leads of the battery cell 2, so that the PCB board 5 and the battery cell 2 are electrically connected. This insertion method can quickly improve production efficiency and battery installation reliability, and avoid the defects caused by traditional welding processes.

[0028] Please see Figure 4 The magnetic connector 6 includes a positive electrode contact 61 mounted on one side of the PCB board 5 and a negative electrode ring 62 surrounding the outside of the positive electrode contact 61. A substrate layer is provided on the surface of the PCB board 5 to cooperate with the positive electrode contact 61 and the negative electrode ring 62. The positive electrode contact 61 and the negative electrode ring 62 are electrically connected to the PCB board 5 through the substrate layer. Furthermore, there is a certain gap between the positive electrode contact 61 and the negative electrode ring 62. This gap can be adjusted according to the external power supply equipment required to be suitable for various battery power supply equipment. It should be noted that the positive and negative electrode pins of the battery cell 2 include positive electrode pins and negative electrode pins. The positive electrode contact 61 is the positive electrode of the battery, and the negative electrode ring 62 is the negative electrode. The positive electrode contact 61 is electrically connected to the positive electrode pin of the battery cell 2, and the negative electrode ring 62 is electrically connected to the negative electrode pin of the battery cell 2.

[0029] Specifically, the positive electrode contact pin 61 has a cylinder 611 electrically connected to the substrate layer of the PCB board 5. The cylinder 611 has an integrally connected contact 612 at one end relative to the PCB board 5. The contact 612 is used to connect with the positive electrode of an external power supply device. A magnet is provided inside the negative electrode ring 62 for magnetic connection with the external power supply device. This allows for quick installation with the power supply device, simple installation and disassembly, and solves the problem of traditional battery installation requiring pressing operations at both ends.

[0030] Furthermore, one end of the housing 1 has an opening 11 that is adapted to the magnetic connector 6. The positive contact pin 61 and the negative ring 62 of the magnetic connector 6 are exposed through the opening 11, which facilitates the installation of the positive contact pin 61 and the negative ring 62 with external power supply equipment.

[0031] Please see Figure 5 The solderless terminal 4 includes a terminal body 41, which is cylindrical. Two symmetrically arranged lugs 42 extend from one side wall of the terminal body 41. The two lugs 42 are fixedly connected to the positive and negative pads of the PCB board 5. The other end of the terminal body 41 is provided with an elastic clamping waist 43 integrally connected to the terminal body 41. The elastic clamping waist 43 has a flared opening with elastic force.

[0032] Furthermore, the base 3 is made of elastic rubber material, and the base 3 has a socket 31 that is compatible with the solderless terminal 4. When the solderless terminal 4 is inserted into the positive and negative pins of the battery cell 2, the elastic clamping waist 43 of the solderless terminal 4 enters the socket 31 and clamps with the positive and negative pins of the battery cell 2. The socket 31 squeezes the flared opening of the elastic clamping waist 43 inward, so that the elastic clamping waist 43 tightly clamps the positive and negative pins of the battery cell 2, thereby forming an electrical connection by clamping the positive and negative pins of the battery cell 2 with the elastic clamping waist 43.

[0033] A control chip 51 is also mounted on the surface of the PCB board 5. The control chip 51 has an overcharge power-off function. When the battery cell 2 is being charged or charging the power supply equipment, if overcharging occurs, the control chip 51 controls the PCB board 5 to disconnect the electrical connection, providing a certain safety function.
