Electronic television, HDMI high definition projectors and HDMI high-definition liquid crystal displays etc..
In family or public arena, the HDMI high definitions electronic equipment of program source is provided and for playing high-definition program content
HDMI high definitions show that equipment often and is not arranged in same room or close distance range, need to connect up connection again.
When being transmitted to video or audio, in order to adapt to the transmission of the vision signal of high definition and the audio signal of lossless sound quality, usually
Using the optoelectronic composite cable with HDMI interface as transmission cable, this optoelectronic composite cable solves traditional copper wire transmission range
Limitation.
However, the HDMI input ports and output port of existing HDMI optoelectronic composite cables are integrated knot with transmission cable
Structure needs when wiring the optoelectronic composite cable with HDMI input ports and output port being arranged in predeterminated position, in construction,
It is easy to damage HDMI input ports and output port, sometimes after construction wiring is completed, port has but been damaged, this is applied
Work causes great inconvenience.And an optoelectronic composite cable is generally only arranged in wiring, circuit is fixed after construction completion,
If circuit breaks down, later period maintenance needs dig up entire circuit, and repair is extremely inconvenient.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.In addition, institute in the various embodiments of the present invention described below
The technical characteristic being related to can be combined with each other as long as they do not conflict with each other.
Fig. 1 show a kind of HDMI Transmission systems with optical connector, including main cable 1, transmitting terminal 2 and receiving terminal 3,
Transmitting terminal 2 and receiving terminal 3 include HDMI connectors 21 and 31, and HDMI connectors 21 and 31 are respectively used to connection output equipment 101 and broadcast
Put equipment 102.It is respectively provided with the first connector 4 and the second connector 5 between transmitting terminal 2, receiving terminal 3 and main cable 1, first
Connector 4 and the second connector 5 are optical connector.When construction, main cable 1 is embedded in wall or conduit, construction party
Just.
Transmitting terminal 2 further includes electrooptic switching element 22, and receiving terminal 3 includes photoelectric conversion unit 32.Electrooptic switching element 22
