The electronic device of the present disclosure includes: a device case 11, a Printed Circuit Board (PCB) 12, and a connector 13. Wherein, the PCB 12 is located in the device housing 11 to carry communications between electronic components of the electronic device, and the connector 13 is disposed at an edge of the PCB 12 to allow external devices to implement communications connection through the connector 13, such as: a USB connector. Preferably, the connection port of the connector 1 is flush with the device housing 11, which not only facilitates connection with external devices but also increases the aesthetic appearance of the electronic device.

The position of the PCB 12 where the connector 13 is assembled is provided with a notch 121, so that the traditional PCB with a large area is removed from the leftover material (i.e. the PCB without the communication function part) for fixing the connector 13, and by such arrangement, not only the area of the PCB 12 can be reduced, but also the use space in the device housing 11 can be increased. Further, the connector 13 partially extends beyond the PCB 12 and does not extend beyond the device housing 11. In the present disclosure, the area of the gap 121 is smaller than the projection area of the connector 13 on the plane of the PCB 12. Thus, the PCB 12 reserves a part of space for accommodating the connector 13 without affecting the communication of the PCB 12.

Specifically, the connector 13 includes a connector body 131, connection pins 132 disposed at a tail portion of the connector body 131, and connection ports 133 disposed at a head portion of the connector body 131. The connecting pins 132 are connected to the PCB 12 and correspondingly connected to the circuit matching the connecting pins 132; the connection port 133 extends beyond the PCB 12, and preferably, the connector body 131 extends beyond the PCB 12 as much as possible on the basis of ensuring the connection stability with the PCB 12, so as to reduce the area of the PCB as much as possible, and thus, from the perspective of a manufacturer, the cost can be saved.
