Description
Technical field
The utility model relates to technical field of electronic components, particularly relates to a kind of electron tube mounting structure.
Background technology
Electron tube is a kind of electric signal amplifier part of earliest period.Be closed in the cathode electronics radiating portion in glass container (being generally glass tube), control gate, accelerating grid electrode, anode (anode) lead-in wire be welded on Guan Ji.Utilize electric field to inject electrical modulation signal to the control gate in vacuum, and obtain the different parameters signal data after to signal amplification or feedback oscillation at anode.Be applied in the electronic product such as television set, broadcast receiver sound amplifier in early days, replaced by the amplifier of semi-conducting material manufacturing and integrated circuit gradually in recent years, but at present in the sound appliances of some high-fidelities, still use the electron tube that low noise, the coefficient of stability are high to be audio-frequency power amplifier part.
The negative electrode pin of current electron tube and anode pin are all be fixedly mounted in the porcelain shell of electron tube, like this when porcelain shell or negative electrode pin, anode pin one are damaged, just all need to change, cause the increase of maintain and replace cost like this, be unfavorable for extensively promoting the use of of electron tube.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of electron tube mounting structure, by negative electrode pin, is installed by screw thread between anode pin and porcelain shell, is convenient to change and dismounting.
The utility model is achieved through the following technical solutions:
A kind of electron tube mounting structure, comprise electron tube porcelain shell, be arranged on negative electrode pin in electron tube porcelain shell and anode pin and described negative electrode pin and anode pin laid out in parallel in electron tube porcelain shell, two installing holes are offered in described electron tube porcelain shell, described installing hole is screwed hole, described negative electrode pin and anode pin are threaded with electron tube porcelain shell, and the bottom of junction is provided with sealing ring.
As optimal technical scheme of the present utility model, the upper end of described sealing ring is fixedly connected with the lower end of electron tube porcelain shell, comes off for preventing negative electrode pin and anode pin.
As optimal technical scheme of the present utility model, the upper end of described electron tube porcelain shell is provided with epoxy resin, and epoxy resin evenly offers circular hole along its length.
As optimal technical scheme of the present utility model, the bilateral symmetry of described electron tube porcelain shell offers installation window.
Compared with prior art, the beneficial effects of the utility model are: negative electrode pin, anode pin and electron tube porcelain shell are threaded connection by the utility model, being convenient to dismounting and changing, simultaneously by being provided with sealing ring, preventing negative electrode pin and anode pin from coming off.
