Wearable device

Abstract

The invention provides a wearable device, and the main body of the wearable device comprises a shell and a shell inner cavity, wherein a charging hole is formed in a lower shell, and a charging connector is installed in the charging hole. A PCB is detachably installed in the shell inner cavity. The charging connector comprises a pin head, a pin tube and a spring piece, wherein the pin head abuts against the PCB to achieve conductive connection, and a sealing ring is installed in a first annular groove in the outer surface of the tube wall of the pin tube in a matched mode and is in interference fit with the charging hole. The principle of the charging connector is the same as that of a pogo pin, and the charging connector is conducted with the PCB through stretching and retracting of the pin head. Moreover, the PCB is detachable and convenient to replace, the lower shell and the PCB cannot be damaged, and the rejection rate is reduced; the charging connector is simple in installation structure, convenient to assemble and especially suitable for being installed in a narrow space. The sealing ring is in interference fit with the charging hole, so that the waterproof performance of the charging connector mounting position is greatly improved.

Description

technical field [0001] The present invention relates to structural improvement of wearable devices. Background technique [0002] At present, the charging connectors on wearable devices on the market are mostly solid copper pillars. Taking smart watches as an example, the copper pillars are interference-fitted into the charging hole on the lower case of the watch, and the top end is connected to the PCB by shrapnel or welding. The back of the watch is conductive, and the PCB is fixed to the watch case by thermal fusion. When connecting with the PCB by soldering, there is little requirement for assembly space, but when the copper pillar needs to be replaced due to poor airtightness, it is necessary to detach the PCB board first to expose the copper pillar for replacement. However, due to the connection between the copper pillar and the PCB Welding conduction, the interference fit between the copper pillar and the watch case, when the PCB board is disassembled, it will inevit...

Problems solved by technology

When connecting with the PCB by soldering, there is little requirement for assembly space, but when the copper pillar needs to be replaced due to poor airtightness, it is necessary to detach the PCB board first to expose the copper pillar for replacement. However, due to the connection between the copper pillar and the PCB Welding conduction, the interference fit between the copper pillar and the watch case, when the PCB board is disassembled, it will inevitably cause tearing and cracking between the copper pillar and the PCB board, resulting in damage to the PCB board, and even the scrapping of the entire lower case; the copper pillar passes through The method of shrapnel and PCB board conduction can effectively solve the above problems. However, this method has a large number of structural parts and requires a large assembly space. It is difficult to assemble in such a small space in the lower case of the watch.
