Description
Technical field
The utility model is related to a kind of data transmission interface, especially compatible audio video transmission interface.
Background technology
Video-frequency connector is generally referred to as BNC video-frequency connectors, and the four-part form that audio connector is generally referred to as national regulations connects
Head (being respectively L channel contact, right channel contact, M1C contacts and earth wire contact from tip to base portion).Due to above-mentioned the two
Between architectural difference it is huge, it is impossible to it is mixed.Since connector difference is so its interface must be also equipped with.
In some special occasions, such as lip reading training, observation group only must receive vision signal and presentation group then can only
Audio signal is received, is usually that different interfaces (preventing from practising fraud) is set for different groups in the prior art, however lip reading is trained
In be necessarily required to exchange group, if using the prior art, that personnel just can only transposition, bring inconvenience.
Invention content
In view of the deficiencies of the prior art, the utility model provides a kind of compatible audio video transmission interface.
The technical solution of the utility model is：
Compatible audio video transmission interface, it is characterised in that：It includes housing, square groove, video-frequency connector female and audio
Interface, the housing are a solid plastic block, and the upper part of the housing is equipped with a square groove, and the square groove bottom end is provided with
Audio interface, the square groove lower sides are provided with several video contacts, and the square groove is embedded in a video-frequency connector
Female, the video-frequency connector female outside, which is enclosed at the top of square insulating sheath and video-frequency connector female, is provided with connection ring, uses
In the male connector of socket video-frequency connector, the video-frequency connector female bottom cooperation video contact is provided with shrapnel described in shrapnel and stretches out absolutely
Except edge sheath.
Specifically, the audio interface include the first sleeve of corresponding earth wire contact, corresponding M1C contacts second sleeve,
The 3rd sleeve of corresponding right channel contact and the 4th sleeve of corresponding L channel contact.
Specifically, the video contact passes through the external video equipment of belt leather conducting wire, first sleeve, second sleeve,
Three sleeves and 4th sleeve pass through belt leather conducting wire external audio frequency equipment respectively.
Specifically, the video-frequency connector female is the female of BNC video-frequency connectors.
Specifically, the square groove side wall is equipped with guide groove, the square insulating sheath outer wall corresponds to guide groove setting
There is guide runner, the conducting wire sliding block is caught in guide groove.
The usage of the utility model：
1) when only exporting video, the BNC video-frequency connectors male connector of display is spirally connected by video-frequency connector female connection ring；
2) when only exporting audio, video-frequency connector female is extracted, national standard 3.5mm headphone plug is inserted into audio interface.
The beneficial effects of the utility model are：By the way that the interface of Voice and Video is arranged in same channel so that
The interface has both two kinds of functions, but single can only use one of which function again so that and training process prevents various cheatings,
The change place time can be saved in the other exchange of training group.
