Abstract

The invention is suitable for the technical field of connectors, and provides an HDMI connector. The HDMI connector comprises a plug and a socket, wherein each of the plug and the socket comprises a housing and multiple pins; the pins in the plug correspond to the pins in the socket; each pin comprises an A attribute pin, a power pin and input / output pins; when the plug is inserted into the socket, the contact order of the plug and the socket is as follows: contact of the socket and the housing of the plug is a first contact order; the contact of the input / output pins in the socket and the input / output pins in the plug is a second contact order; the contact of the A attribute pin in the socket and the A attribute pin in the plug is a third contact order; and the contact of the socket and the power pin in the plug is a fourth contact order. According to the HDMI connector, through changing the contact order of the pins when the plug is inserted into the socket, a failure, caused by surge impact, of the A attribute pins in the third contact order can be avoided by priority contact in the second contact order even if in a function failure of the first contact order.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to an HDMI connector and a Blu-ray player with the HDMI connector. Background technique [0002] The HDMI1.4a specification originally stipulated the contact sequence of the pins of the HDMI A-type plug inserted into the A-type socket. The contact sequence requirements are: the first contact sequence is the HDMI A-type socket and the HDMI A-type plug shell contact, the second The second contact sequence is that pins 1–17 and pin 19 of the HDMI Type A socket correspond to pins 1-17 and pin 19 of the HDMI Type A plug, and the third contact sequence is the HDMI Type A socket and HDMI Type A plug of pin 18 contacts. [0003] The HDMI Type A plug is part of the HDMI cable. The quality of HDMI cable manufacturers varies greatly, and the HDMI cable may cause the shell of the first contact sequence to fail during use by the user and not have electrical conduction characteristics.
