Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings 1-3 and the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The back clip type mobile power supply includes a housing 1 and a battery and a circuit board accommodated in the housing 1, and the battery is electrically connected to the circuit board, and the housing 1 is provided with a The connector 2 is molded and used to connect to the charging interface of a mobile phone or a tablet computer, and the connector 2 is electrically connected to the circuit board. Here, the housing 1 and the connector 2 are both made of insulating materials, such as insulating plastics, insulating rubber, and the like. In this way, in this embodiment, by providing the connector 2 integrally formed with the housing 1 on the housing 1, the overall structure of the clip-on mobile power supply can be made more compact, which facilitates the layout of other components. It is beneficial to improve the overall aesthetic design of the clip-on mobile power supply.

In this embodiment, a first clamping block 11 extending from the housing 1 to the upper side of the housing 1 is provided on a periphery of the housing 1 , and the connector 2 is clamped by the first clamping block 11 . The block 11 extends horizontally towards the inside of the housing 1 . In this way, the first clamping block 11 is arranged on the housing 1, and the connector 2 is arranged on the first clamping block 11 and extends horizontally toward the inside of the housing 1, so that the entire back clamp The length of the clip-on mobile power supply is basically the same as that of the mobile phone or tablet computer used in conjunction with it, which improves the convenience and beautiful design of the back-clip mobile power supply.
