A Universal Serial Bus (USB) modem is provided. The USB modem includes a USB plug (1), a Printed Circuit Board (PCB) (2), and a signal input apparatus (3) that connects the USB plug (1) and the PCB (2). The signal input apparatus includes: a support (4) that is disposed on the PCB (2), in which the USB plug is disposed on the support (4); and a connector (5) that is disposed on the PCB and capable of being connected to the USB plug (5). The USB modem implements signal input by adopting the connector (5), thereby extending the service life of the USB modem and greatly reducing the cost. |
