Abstract
Description
Technical Field
[0001] This utility model relates to the field of electron tube socket technology, and in particular to a high-precision, airtight electron tube socket. Background Technology
[0002] Vacuum tubes are one of the earliest electrical signal amplification devices. A vacuum tube is enclosed in a glass container (usually a glass tube), with the cathode electron emitting part, control grid, accelerating grid, and anode (plate) leads soldered to the tube base. Early applications included televisions, radios, and amplifiers. In recent years, however, they have been gradually replaced by amplifiers and integrated circuits made of semiconductor materials. Vacuum tubes now require a vacuum tube socket for use.
[0003] Most existing vacuum tube sockets rely solely on the insertion of a limiting post at the bottom of the vacuum tube into a limiting slot at the top of the socket to control the tube's position and allow the tube's pins to be inserted into the pin sockets for proper use. However, because the limiting post at the bottom of the tube is not properly secured, the tube is susceptible to slight rotation under external forces during use. This rotation can cause the tube's pins to bend and become damaged, thus reducing the protection of the tube. Therefore, it is necessary to propose a high-precision, airtight vacuum tube socket to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision, airtight electron tube socket to solve the problem mentioned in the background art, which is that without limiting and fixing the bottom of the electron tube, the electron tube is prone to slight rotation above the socket under the action of external force during use. This rotation can easily cause the pins of the electron tube to bend and be damaged, thereby reducing the protection of the electron tube.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision airtight electron tube socket, comprising an electron tube socket body, wherein a tube pin is fixedly connected to the bottom of the electron tube socket body, and a pin insertion hole is provided on the top of the electron tube socket body, and a limit slot is provided on the top of the electron tube socket body.
[0006] The limiting slot is provided with a limiting component inside. The limiting component includes a slider, a limiting plate, a rubber pad, and a limiting spring. A positioning groove is provided at the bottom of the limiting slot. The inside of the positioning groove is slidably connected to the outside of the slider. The top of the slider is fixedly connected to the bottom of the limiting plate. The outside of the slider is fixedly connected to one end of the limiting spring. The outside of the limiting plate is fixedly connected to the outside of the rubber pad.
[0007] The top of the electron tube socket body is provided with a rotating groove, and a sealing component is provided inside the rotating groove.
[0008] Preferably, the limiting plate is arc-shaped, and there are four limiting plates, which are arranged in a circumferential array inside the limiting slot.
[0009] Preferably, the other end of the limiting spring is fixedly connected to the inside of the limiting slot.
[0010] Preferably, the sealing assembly includes a rotating ring, a sealing plate, and rubber sealing rings. The outer side of the rotating ring is rotatably connected to the inner side of the rotating groove, and the outer side of the rotating ring is fixedly connected to the outer side of the sealing plate. The sealing plate has multiple through holes inside, and rubber sealing rings are fixedly connected to the interior of each of the multiple through holes.
[0011] Preferably, a connecting plate is fixedly connected to the outside of the electron tube socket body, and the connecting plate has mounting holes inside.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. By setting a limiting component, when the limiting post at the bottom of the electron tube is inserted into the limiting slot at the top of the electron tube socket body, the compressed limiting spring will restore its elasticity. The slider will drive the limiting plate to move, and together with the rubber pad, it can limit and fix the limiting post at the bottom of the electron tube. This avoids the electron tube from slightly rotating above the electron tube socket body under the action of external force during use, which could easily cause the pins of the electron tube to bend due to rotation and damage the pins of the electron tube. This improves the protection of the electron tube.
[0014] 2. By setting up a sealing component, when the electron tube pin is inserted into the pin socket, its rubber sealing ring will seal the top of the electron tube pin, preventing dust from entering the pin socket from the connection gap between the electron tube and the electron tube socket body. When the electron tube needs to be replaced or is not in use, the sealing plate can be rotated so that the through hole opened inside the sealing plate does not coincide with the pin socket. That is, the sealing plate is used to seal the pin socket, preventing dust from entering the interior of the pin socket and causing inconvenience for subsequent use of the electron tube, thereby further improving the sealing performance of the electron tube socket.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figures 1-5 The high-precision airtight electron tube socket shown includes an electron tube socket body 1. A pin 2 is fixedly connected to the bottom of the electron tube socket body 1, and a pin insertion hole 3 is opened at the top of the electron tube socket body 1. A limit slot 4 is opened at the top of the electron tube socket body 1. A limit component is installed inside the limit slot 4, including a slider 6, a limit plate 7, a rubber pad 8, and a limit spring 9. A positioning groove 5 is opened at the bottom of the limit slot 4, and the inside of the positioning groove 5 is slidably connected to the outside of the slider 6. The top of the slider 6 is fixedly connected to the bottom of the limit plate 7, and the outside of the slider 6 is fixedly connected to one end of the limit spring 9. The outside of the limit plate 7 is fixedly connected to the outside of the rubber pad 8. The limit plate 7 is arc-shaped, and there are four limit plates 7 arranged in a circumferential array inside the limit slot 4. The other end of the limit spring 9 is fixedly connected to the inside of the limit slot 4. When the limiting post at the bottom of the electron tube is inserted into the limiting slot 4 at the top of the electron tube socket body 1, the compressed limiting spring 9 will restore its elasticity and move the limiting plate 7 through the slider 6. Together with the rubber pad 8, it can limit and fix the limiting post at the bottom of the electron tube, thus preventing the electron tube from slightly rotating above the electron tube socket body 1 under the action of external force during use. This would easily cause the pins of the electron tube to bend due to rotation and damage the pins of the electron tube, thereby improving the protection of the electron tube.
[0023] In addition, a rotating groove 10 is provided on the top of the electron tube socket body 1. A sealing assembly is provided inside the rotating groove 10. The sealing assembly includes a rotating ring 11, a sealing plate 12, and a rubber sealing ring 13. The outside of the rotating ring 11 is rotatably connected to the inside of the rotating groove 10, and the outside of the rotating ring 11 is fixedly connected to the outside of the sealing plate 12. The inside of the sealing plate 12 has multiple through holes, and the inside of each of the multiple through holes is fixedly connected to a rubber sealing ring 13. When the electron tube pin is inserted into the pin socket 3, the rubber sealing ring 13 seals the top of the electron tube pin, preventing dust from entering the pin socket 3 from the connection gap between the electron tube and the electron tube socket body 1. When the electron tube needs to be replaced or is not in use, the sealing plate 12 can be rotated so that the through holes inside the sealing plate 12 do not coincide with the pin socket 3. That is, the sealing plate 12 is used to seal the pin socket 3, preventing dust from entering the inside of the pin socket 3 and causing inconvenience for the subsequent use of the electron tube, thereby further improving the sealing performance of the electron tube socket.
[0024] Finally, a connecting plate 14 is fixedly connected to the outside of the electron tube socket body 1, and the connecting plate 14 has mounting holes 15 inside. The connecting plate 14 can be used to fix the electron tube socket body 1 to the circuit board, which facilitates the use of the electron tube socket body 1.
[0025] Working Principle: The connecting plate 14 can be used to fix the electron tube socket body 1 to the circuit board, facilitating its use. When the limiting post at the bottom of the electron tube is inserted into the limiting slot 4 at the top of the electron tube socket body 1, the compressed limiting spring 9 will restore its elasticity, causing the limiting plate 7 to move via the slider 6. This, combined with the rubber pad 8, effectively limits and fixes the limiting post at the bottom of the electron tube, preventing the electron tube from slightly rotating above the electron tube socket body 1 under external force during use. This prevents the electron tube pins from bending due to rotation, which could damage the pins. This design improves the protection of the electron tube. When the electron tube pins are inserted into the pin socket 3, the rubber sealing ring 13 seals the top of the electron tube pins, preventing dust from entering the pin socket 3 through the gap between the electron tube and the electron tube socket body 1. When the electron tube needs to be replaced or is not in use, the sealing plate 12 can be rotated so that the through hole inside the sealing plate 12 does not coincide with the pin socket 3. That is, the sealing plate 12 is used to seal the pin socket 3, preventing dust from entering the interior of the pin socket 3 and causing inconvenience for the subsequent use of the electron tube, thereby further improving the sealing performance of the electron tube socket.
