Description

Improved electric connector

Technical field

The utility model provides a kind of improved electric connector, espespecially the electric connector of switching signal transmission, in insulation The terminal groove in the grafting space of pedestal wears the signal terminal of terminal group, inspection terminal, and is covered outside insulating base frame outside metal Shell, using contact or disconnection of the signal terminal with inspection terminal, achievees the purpose that to switch electric connector work.

Background technology

As electronics technology continues to develop, electronic device such as TV, recorder, videocorder, CD for playing audio-visual are broadcast Put device, digital video disk player (DVD), family's theater and broadcast also a large amount of appearances such as system, for playing audio-visual, video image Screen or display etc. in application function, broadcast effect etc. and also lifted therewith, then be used for transmission the input of video-audio signal/ Also there occurs many changes, general common audio-visual terminal to include AV terminal, S terminals and color for the species of lead-out terminal, pattern Poor terminal etc., and the S terminals and aberration terminal be only used for transmission signal of video signal, AV terminal except for transmission signal of video signal it Outside, it can be used for transmission audio signal；Common signal of video signal is mostly that after light is carried out color separation by image-forming component, can obtain To the tristimulus signal of red, green, blue, then it is converted into colour difference signal of the luminance signal (Y) of performance lightness with representing color (Chrominance), colour difference signal can be divided into two kinds of signals of Pr, Pb (or Cr, Cb), then luminance signal and two kinds of colour difference signals It can be transmitted by aberration terminal (Component-Vido)；Usual S terminals can be used to output brightness and color separated Signal (two of which colour difference signal is mixed), what AV terminal can transmit that brightness mixes with colour difference signal blendes together signal (Composite-Vido)。

Currently used AV terminal transmission line, both sides carry out the transmission of video-audio signal by three RCA connectors respectively, and Three RCA connectors all can dispensing different colours, to distinguish the function of its transmission signal, typically with white, red, yellow three kinds of face Color indicates, and for white therein with red R CA connectors to transmit audio signal, yellow RCA connectors are then transmission images Vision signal, also referred to as blendes together image terminal；Another S terminals, that is, Super Signal terminal (Super-Vido), and S terminals Transmission line both sides be respectively cylindrical connector, four terminal pin holes are internally provided with circular iron-clad, for opposing connector Four terminal needle bodies are inserted into corresponding terminal pin hole, and be transmitted that brightness mixes with colour difference signal blendes together signal；Also, the color Poor terminal is also utilized respectively three RCA connectors in transmission line both sides and carries out video-audio signal transmission, and three kinds of different colours of dispensing Be made for distinguishing, respectively green, blue, red three kinds of colors, its green RCA connector to transmit luminance signal (Y), and blueness, Red RCA connectors are used for transmission colour difference signal (Pb, Pr or Cb, Cr)；Then the transmission line of various types is in practical application When, it need to be only plugged on respectively on the RCA connectors of corresponding color on electronic product according to the different colours of RCA connectors, you can Carry out the transmission of video-audio signal.

Therefore, general video-audio signal player (such as videocorder or DVD player) can all add the S ends of three kinds of patterns Sub- transmission line, AV terminal transmission line and aberration terminal transmission line etc., and connect video-audio signal output, the electronic device (shadow of input Sound player and display etc.) must possess the multigroup output port and input port of three kinds of patterns, transmitted respectively for S terminals The cylindrical connector of line, three RCA connectors of AV terminal transmission lines, three RCA connectors of aberration terminal transmission line carry out Grafting, and the signal transmission form of various transmission lines is to work independently, multiple RCA connectors carry out luminance signal, shadow respectively It as the transmission of signal, and can not carry out detecting the signal transfer mode between each RCA connectors, common cannot also use, switch Deng causing the elder generation of multigroup transmission line the missing such as easily to interfere with each other, be entangled with or pull certainly, i.e., still exist when practical application is implemented Many missings, it is to be improved.

Therefore, the problems such as wire rods of a variety of video-audio signal transmission wires is easily disturbed, is entangled with or pullled how is solved, and it is a variety of Signal transmssion line independently works, common can not use the trouble switched over and inconvenience, is as engaged in the correlation of the industry Manufacturer desires most ardently the direction that research improves.
