Description
Technical field
The utility model relates to video socket improvement technology.
Background technology
In the prior art, video socket is directly with coupling like the nipple of video-frequency connector in the TV connector socket that is installed on connection TV in the body of wall and is connected with outside line, does not take any safeguard measure.Since outside line the circumstance complication of process, may receive various electromagnetic interference and make the signal transmission unstable, it is unusual that the equipment acknowledge(ment) signal is occurred.
The utility model content
In view of this, the utility model technical problem that will solve provides a kind of video socket with interference free performance.
The utility model adopts following scheme to realize:
A kind of video socket; Comprise the video-frequency connector with nipple and coupling and pcb board, the metal fixed head of permanent joint; Joint, pcb board and metal fixed head all are fixed in the shell of socket; The metal fixed head is provided with heart yearn terminal that is fixedly connected the coaxial line heart yearn and the screen terminal that is fixedly connected the coaxial line screen; Heart yearn terminal and nipple electrically connect, and screen terminal and coupling electrically connect, between heart yearn terminal and the nipple, all be in series with electric capacity between screen terminal and the coupling.
As the improvement to such scheme, described two electric capacity are packaged in the coupling outside through injection moulding, and described heart yearn terminal is fixed in pcb board and the off-centered position of metal fixed head through fixed screw, insulate between heart yearn terminal and the metal fixed head.Connect between screen terminal and the coupling electric capacity wherein a pin contact with coupling and realizes conducting, another pin passes pcb board and contacts realization with the metal fixed head and conduct, the screen terminal directly contacts realization with the metal fixed head and conducts.
As another improvement to such scheme, two electric capacity are perhaps patch capacitor of ceramic electrical, are fixedly welded on the pcb board.Described heart yearn terminal is fixed on the pcb board through fixed screw,, heart yearn terminal and nipple concentric are provided with.Connect between screen terminal and the coupling electric capacity wherein a pin contact with coupling and realizes conducting, another pin passes pcb board and contacts realization with the metal fixed head and conduct, the screen terminal directly contacts realization with the metal fixed head and conducts.
The utility model makes whole socket have effects such as anti-interference, anti-thunderbolt, isolated DC electricity, High frequency filter, coupling, resonance through between the video-frequency connector of socket and heart yearn terminal, screen terminal, setting up electric capacity, has further guaranteed stability and fail safe that signal transmits.And the utility model can directly be transformed acquisition on existing video socket, and the compatible installation requirement of existing video socket has reduced transformation, cost of manufacture.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representations.
Embodiment
Below will combine accompanying drawing and embodiment that the utility model is described in further detail for the ease of it will be appreciated by those skilled in the art that:
Embodiment one:
Be depicted as present embodiment video socket structural representation like accompanying drawing 1; This video socket comprises having nipple 11 and the video-frequency connector 1 of coupling 12 and pcb board 2, the metal fixed head 3 of permanent joint 1; Video-frequency connector 1, pcb board 2 and metal fixed head 3 all are fixed in the shell 4 of socket; Metal fixed head 3 is provided with heart yearn terminal 5 that is fixedly connected the coaxial line heart yearn and the screen terminal 6 that is fixedly connected the coaxial line screen; Heart yearn terminal 5 electrically connects with nipple 11; Screen terminal 6 electrically connects with coupling 12, has effects such as anti-interference, anti-thunderbolt, isolated DC electricity, High frequency filter, coupling, resonance in order to make this socket, between heart yearn terminal 5 and the nipple 11, all be in series with electric capacity 8 between screen terminal 6 and the coupling 12.
The electric capacity that present embodiment adopts is ceramic condenser; Because the ceramic condenser volume is big; For prevent to install and in use for a long time electric capacity get loose or damage, two electric capacity 8 are packaged in coupling 12 outsides through injection moulding, are encapsulated as an integral body with coaxial fitting 1.Described heart yearn terminal 5 is fixed in pcb board 2 and metal fixed head 3 off-centered positions through fixed screw 7, insulation between heart yearn terminal 5 and the metal fixed head 3.And connect between screen terminal 6 and the coupling 12 electric capacity wherein a pin contact realization with coupling 12 and conduct; Another pin passes pcb board 2 and contacts with metal fixed head 3 and realize conducting, and screen terminal 6 directly contacts realization with metal fixed head 3 and conducts.
Present embodiment can directly be transformed acquisition on existing video socket, the compatible installation requirement of existing video socket has reduced transformation, cost of manufacture.
Embodiment two:
Be depicted as another implementation structural representation of the utility model like accompanying drawing 2.Present embodiment can directly be transformed on existing video socket equally; With difference in embodiment one mode be electric capacity be chosen as the less patch capacitor of volume 8; Patch capacitor 8 directly is fixedly welded on the pcb board 2; And heart yearn terminal 5 is fixed on this pcb board 2 through fixed screw, heart yearn terminal 5 and nipple 11 concentric settings.And connect between screen terminal 6 and the coupling 12 electric capacity wherein a pin contact realization with coupling 12 and conduct; Another pin passes pcb board 2 and contacts with metal fixed head 3 and realize conducting, and screen terminal 6 directly contacts realization with metal fixed head 3 and conducts.
This embodiment can need not to carry out the injection moulding encapsulation, just in pcb board, sets up corresponding circuit and gets final product.
More than be the wherein concrete implementation of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these conspicuous replacement forms all belong to the protection range of the utility model.
