Description

MHL cable {MHL CABLE}

The present invention relates to an MHL cable, and more particularly, to an MHL cable capable of switching to first and second MHL systems through a switch.

Mobile phones such as smart phones and tablets provide users with various useful functions through various applications. Accordingly, the portable terminal is becoming a device that can utilize various types of information in addition to a voice call function by providing various functions. In particular, such a portable terminal provides a data input / output function connected to an external device to output data from an external device or input data to an external device.

In order to provide such a data input / output function, the portable terminal and the external device must be connected in a specific connection manner. Here, the specific connection method includes a USB (Universal Serial Bus) method and a MHL (Mobile High-Definition Link) method. The MHL method is a technology in which 13 lines of HDMI (High Definition Multimedia Interface) It is compatible with the standard micro USB method using a 5-pin connector. However, this MHL method has a limitation that it can not support the USB method and the MHL method at the same time. To overcome these limitations, certain manufacturers have devised an 11-pin connector that supports USB and MHL simultaneously.

However, since a general cable supports a 5-pin connector or an 11-pin connector, a general cable can connect only a portable terminal of a supported specification, so that the compatibility of the cable is deteriorated. Therefore, there has been a need for a cable that simultaneously supports 5-pin connectors and 11-pin connectors.
