With the advent of the mobile Internet era, the popularity of high-definition portable devices (such as smart phones and tablet computers) is an inevitable trend. The high-definition audio-visual content stored on the high-definition portable device can be directly played by the high-definition portable device, but due to the limitation of its screen size and other aspects, it cannot bring users perfect sound and visual enjoyment. Users hope to transmit high-definition video and audio content stored on high-definition portable devices to high-definition TVs for playback, so as to enjoy high-quality sound and images. Thus, a mobile high-definition interface (Mobile High-Definition Link referred to as MHL) came into being. MHL can transmit high-definition audio and video content on high-definition portable devices to high-definition TV for playback, providing users with high-quality sound and visual enjoyment. High-definition portable devices still use the current charging method, that is, two signal lines are required in the sales accessories of high-definition portable devices: one USB signal line is used to charge high-definition portable devices, and one MHL signal line is used to transmit data to high-definition TVs. High-definition audio and video content, through the USB interface of the USB signal cable, connect to the computer to charge, or connect to the AC charger through the USB interface of the USB signal cable, and then connect to the AC power supply for charging. This not only increases the sales cost of the high-definition portable device, but also brings inconvenience to the user's use and portability.

Detailed ways

The utility model will be further described in conjunction with the following examples.

An interface converter in this embodiment includes a housing 1 integrally formed by die-casting zinc alloy, a rubber core 2 integrally formed in the housing 1 by insert injection molding and a terminal 3 integrally stamped and formed. The housing 1 is composed of an HDMI female housing 11 and a USB male housing 12 connected to each other. The rubber core 2 and the terminal 3 pass through the channel formed in the housing 1. The rubber core 2 and the terminal 3 At the same time, it is used as the rubber core and terminal of the HDMI female seat and the USB male seat.

One end of the MHL signal cable is an interface for plugging in a high-definition portable device, and the other end is an HDMI interface for plugging in an HDMI socket of a high-definition TV. There are A, B, C, and D types of HDMI interface. The HDMI female socket on the high-definition TV is a type A female socket, and the HDMI female socket of this converter is also a type A HDMI female socket. The USB interface of the computer or the charger is generally a type A USB female socket, and the USB male socket of this converter is also a type A USB male socket.
