An apparatus for indicating the position of a USB port of a mobile phone. At present, when a common mini USB or micro USB of a digital device such as a mobile phone is used under poor lighting conditions, misalignment, use inconvenience and even interface damage are easily caused during insertion. The technical solution of the present invention utilizes a transparent plastic piece having a light guiding effect plus an LED lamp having a built-in interface in combination with a virtual screen lock button or an on/off button to provide corresponding interface direction indication and outline marking and reverse prevention functions for using the mobile terminal at night. The technical solution solves the problem that a peripheral interface of digital and terminal devices is inconvenient to use at places with poor lighting, reduces the possibility of failing to achieve smooth insertion into the interface at one attempt, protects relevant interface devices and achieves a beautifying effect. |
