[0002] Mobile phone lithium battery cables are widely used to connect the power supply between the lithium battery and the phone's circuit board. However, the positions of the positive and negative power contacts on the circuit boards of different phone brands and models vary. Because existing cables are not universal, assembling different phone brands and models requires purchasing or customizing cables that match the positions of the positive and negative contacts on the phone's circuit boards. This increases the complexity of cable material management for mobile phone manufacturers. Summary of the Invention
[0003] The problem to be solved by the present invention is to provide a lithium battery cable suitable for a variety of mobile phone models, which is applicable to mobile phones of different brands and models and has universality.
[0004] To solve the above technical problems, a lithium battery cable suitable for various mobile phone models is provided in accordance with the utility model, which includes a strip-type substrate and a strip-type flexible circuit board. One end of the strip-type flexible circuit board is connected to one end of the strip-type substrate. The top surface of the strip-type substrate is provided with a battery positive contact pin and a battery negative contact pin. The top surface of the strip-type flexible circuit board is provided with a board positive contact pin and a board negative contact pin. The battery positive contact pin and the battery negative contact pin are electrically connected to the board positive contact pin and the board negative contact pin respectively.
[0005] Preferably, the strip-shaped substrate is an FR-4 glass substrate.
[0006] Preferably, the surfaces of the strip-type substrate and the strip-type flexible circuit board are both provided with an insulating layer.
[0007] The beneficial effects of the present invention are as follows: the present invention provides a lithium battery cable suitable for various mobile phone models. When in use, the strip-shaped substrate is placed tightly against one end face of the lithium battery, and the positive and negative contacts of the battery are respectively in contact with the positive and negative poles of the battery. The strip-shaped flexible circuit board is then superimposed on the back of the strip-shaped substrate. Since the strip-shaped flexible circuit board has sufficient adjustable length, the strip-shaped flexible circuit board can be moved to align the positive and negative contacts of the board with the positive and negative contacts of the mobile phone circuit board. The excess length of the strip-shaped flexible circuit board can be overlapped and arranged on one side of the lithium battery, and the strip-shaped flexible circuit board is fixed with adhesive tape. When the battery is assembled on the mobile phone, the positive and negative contacts of the board can be in contact with the positive and negative contacts of the mobile phone circuit board. The structure is simple, suitable for mobile phones of different brands and models, and has universality, which facilitates mobile phone manufacturers to assemble mobile phone batteries and is worthy of promotion and use.
