Technical field

The utility model relates to a kind of terminal, and more particularly, it relates to a kind of plug-in AV terminal.

Background technology

General television set, Video Recorder, impact, loudspeaker ... etc., output or the input of the signals such as its image, sound, mostly be to be connected by signal connector set on body, and obtain nationality, by signal line, be plugged on plug-in AV terminal to be connected on aforesaid electrical equipment, make to transmit the signals such as image or sound.

And it is general in order to connect the signal connector of video signal or sound equipment, by socket and plug, formed, be aforementioned alleged plug-in AV terminal, this socket operated by rotary motion is on the circuit board of electrical equipment, plug is installed on the two ends of signal line, therefore, by the plug of signal line, be plugged on the plug of electrical equipment to connect two audio-visual appliances, and by signal line, transmitted the electric signals such as image or sound.

At present, on market, normally used plug-in AV terminal is comprised of plug and socket, and on the inserting column of plug, be provided with flexible tab or be provided with flexible tab on plug sleeve, thus abundant contact and the contact engaging and separating force of assurance plug and socket.

And because the socket of signal connector has been installed and is fixed on electrical equipment when dispatching from the factory, but the selected electrical equipment such as video signal sound equipment of consumer not all come from Yi Jia manufacturer, and because manufacture the problem of keeping away unavoidable manufacturing tolerance, likely due to material, design, the reasons such as technique cause between the unreliable plug and socket causing of structure, undesired separated between contact pin and jack, the serious consequence that will cause control system delivery of electrical energy and signal controlling to interrupt; Even if guaranteed sufficient contact engaging and separating force, but under severe working condition, plug and socket still exist owing to shaking or touching wire but problem that plug and socket get loose.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of plug-in AV terminal, and it can effectively solve the plug and the undesired separated of socket and the problem getting loose of prior art, and the complete clamping of plug and socket is provided.

For achieving the above object, the utility model provides following technical scheme: a kind of plug-in AV terminal, comprise socket and plug, on described socket, comprise pedestal and be located at the metallic sheath on pedestal, described plug comprises inserting column and sleeve, the front end of described sleeve is provided with projection, on described metallic sheath, be arranged with positive stop, in described positive stop, be provided with latch circle, in described latch circle, be provided with circumferentially uniform elastic latch, the opposite side of the relative pedestal of described positive stop is provided with backstop, described backstop is provided with for pushing the presenting a theatrical performance as the last item on a programme of boss shape of described latch, described presenting a theatrical performance as the last item on a programme is penetrated with the through hole inserting for inserting column.

By adopting technique scheme, make plug when inserting socket, elastic latch on the projections press latch circle of the sleeve of plug, elastic latch is expanded, until projection passes completely through latch circle, elastic latch shrinks, projection is blocked by the elastic latch of latch circle, prevent plug and the undesired separated of socket and the generation getting loose, when needs are normally extracted, press backstop, present a theatrical performance as the last item on a programme to squeeze and open the elastic latch on latch circle, projection is enough to through latch circle, thereby plug is extracted, the plug and the undesired separated shortcoming with getting loose of socket of prior art have been solved thus.

The utility model is further set to: described pedestal is fixedly connected with described positive stop.

By adopting technique scheme, realized being fixedly connected with of socket base and positive stop, become an integral body, solved the socket base problem separated with positive stop.

The utility model is further set to: between described positive stop and backstop, be provided with spring.

By adopting technique scheme, make backstop do not press down in situation, by spring supporting, the Long Term Contact of having avoided presenting a theatrical performance as the last item on a programme with latch circle latch, thereby the broken flexible problem of piece latch.

The utility model is further set to: described positive stop is equipped with front spring stopper slot.

By adopting technique scheme, make spring when packing between positive stop and backstop, by the front spring stopper slot of positive stop, limited, avoided spring because of the spacing problem not exclusively being flown by bullet.

The utility model is further set to: in described backstop, be equipped with the rear spring stopper slot concentric with described latch circle slot to make way.

By adopting technique scheme, make spring when packing between positive stop and backstop, also spacing firmly by rear spring stopper slot when spring is limited by front spring stopper slot, further promoted the stability of spring between positive stop and backstop.

The utility model is further set to: described positive stop is equipped with latch circle stopper slot.

By adopting technique scheme, can make latch circle and front back-up ring become two parts, and when latch circle packs positive stop into, spacing firmly by latch circle stopper slot, when the latch in latch circle has damage, can realize replacing easily by changing latch circle.

The utility model is further set to: in described backstop, be equipped with and described latch circle slot to make way of presenting a theatrical performance as the last item on a programme concentric.

By adopting technique scheme, when backstop is pressed down, avoid the touching of latch circle and backstop, thereby realize pressing down completely of backstop.

The utility model is further set to: between described positive stop and backstop, be also provided with guiding locking mechanism.

By adopting technique scheme, can make positive stop and backstop in locking, backstop can also directionally move mutually, has extended useful life and the safety in utilization of plug-in AV terminal.

The utility model is further set to: described guiding locking mechanism comprises support plate screw, be arranged on the screwed hole of described positive stop and be arranged on the through hole of described backstop, and described support plate screw is connected with screwed hole through after through hole.

By adopting technique scheme, realized simply and easily the locking guide function of backstop and positive stop.
