Description

Technical Field

[0001] This invention belongs to the field of electron tube socket technology, specifically a tensile-resistant electron tube socket for precision electronic components and its processing technology. Background Technology

[0002] A vacuum tube is one of the earliest electrical signal amplification devices. The cathode electron emitting part, control grid, accelerating grid, and anode lead are all enclosed in a glass container and soldered to the tube base. An electric field is used to inject electrons into the control grid in the vacuum to modulate the signal, and different parameter signal data are obtained at the anode after signal amplification or feedback oscillation.

[0003] The existing cathode lead-out structure of electron tube die pillars includes an inner cathode lead-out ring, a connecting ring on the outer circumferential surface of the inner cathode lead-out ring, and a pressure ring on the upper part of the connecting ring. When replacing some high-power electron tubes, the cathode of the electron tube die pillar is easily damaged, making it inconvenient to lead out the cathode of the electron tube die pillar.

[0006] The fixing mechanism includes a guide post fixed in a groove, a bidirectional lead screw rotatably connected to the guide post in the groove, two nuts symmetrically threaded on the outer side of the bidirectional lead screw, two guide plates symmetrically and movably sleeved on the outer side of the guide post, the two guide plates being fixed to the top of the two nuts respectively, two slide rods symmetrically and fixedly connected inside the groove, a slide plate movably sleeved between the two slide rods, the slide plate being located below the bidirectional lead screw, two movable rods symmetrically and rotatably connected on the outer side of the slide plate, the tops of the two movable rods being rotatably connected to the bottom of the two nuts respectively, two top rods symmetrically and fixedly connected to the top of the slide plate, the guide post and the two bidirectional lead screws being located between the two top rods, a base block fixedly connected to the bottom center of the electron tube core post, the bottom of the base block extending into the groove and located above the guide post, two bottom sleeves symmetrically and fixedly connected to the bottom of the base block, the two bottom sleeves being located directly above the two top rods respectively, and the inner diameter of the two bottom sleeves being equal to the outer diameter of the two top rods.

[0007] Preferably, the bottom block is located between two guide plates, and the bottom block is provided with a limiting hole. A limiting post is fixedly connected to the side of the two guide plates that are close to each other, and the two limiting posts are inserted into the limiting hole.

[0008] Preferably, the groove has an inner plate inside, and a support plate is fixedly connected between the bottom of the inner plate and the inner bottom wall of the groove. A drive shaft is rotatably connected to the side of the inner plate near the slide plate, and a handwheel is fixedly installed on the outside of the drive shaft.

[0009] Preferably, one end of the bidirectional lead screw is fixedly connected to a side shaft located above the drive shaft, a small gear is fixedly installed on the outer side of the side shaft, and a large gear is fixedly installed on the outer side of the drive shaft, with the large gear meshing with the small gear.

[0010] Preferably, the protective mechanism includes a protective plate movably installed in the groove, the side of the protective plate away from the handwheel being fitted with the inner plate, and the protective plate having a through hole.

[0011] Preferably, a vertical plate is fixedly installed inside the groove, the end of the drive shaft away from the inner plate is rotatably connected to the vertical plate, the side shaft passes through the vertical plate and is rotatably connected to the vertical plate, and one end of the guide column is fixedly connected to the vertical plate.

[0012] Preferably, a side plate located above the side axis is fixedly connected to the side of the protective plate near the upright plate, and a slider is fixedly connected to the side of the side plate away from the protective plate through the upright plate. The slider is movably sleeved on the outside of the guide post, and a spring is fixedly connected between the slider and the upright plate. The spring is sleeved on the outside of the guide post.

[0015] A fabrication process for a pull-type electron tube socket used in precision electronic components includes the following steps:

[0016] Step 1: First, the handwheel is exposed by the protective mechanism, and at the same time, the locking mechanism releases the restriction on the side shaft.

[0017] Step 2: Then rotate the handwheel to drive the side shaft to rotate, and move the two limit pins away from each other and out of the limit hole, thus releasing the fixation of the bottom block;

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, through the cooperation between the drive shaft, large gear, small gear, side shaft, double-acting lead screw and lead nut, when the handwheel is rotated, both guide plates slide along the guide post, allowing the two limiting posts to move out of the limiting holes, facilitating the release of the base block from the base. Through the cooperation between the movable rod, the sliding plate and the sliding rod, the two top rods rise and insert into the two bottom sleeves respectively, thereby pushing the base block upward, facilitating the disengagement of the electron tube cathode pin from the insertion hole, thus facilitating the lead-out of the electron tube core cathode.

[0021] 2. This invention, through the cooperation between the guide post, slider, upright plate, spring and side plate, facilitates the fit between the protective plate and the inner plate, blocking the through hole, thereby protecting the handwheel and preventing it from rotating due to external force. This ensures that the cathode pin of the electron tube is stably located in the socket and improves tensile strength.

[0022] 3. This invention facilitates the engagement of the locking gear and the pinion gear through the cooperation between the guide column, slider, upright plate, spring, side plate, drive rod, lifting plate, L-shaped round rod and connecting frame, and can limit the side shaft, thereby further ensuring the stable connection between the electron tube core column and the base.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1, by Figures 1-8 The present invention relates to a tensile-resistant electron tube socket for precision electronic components, comprising a base 1, an electron tube core 8 at the bottom of the base 1, a glass tube 9 at the top of the electron tube core 8, a plurality of insertion holes 6 on the base 1, a plurality of electron tube cathode pins 7 fixedly connected to the bottom of the electron tube core 8, each electron tube cathode pin 7 being inserted into a respective insertion hole 6, and a groove 5 on the base 1, wherein a fixing mechanism 2, a protective mechanism 3 and a locking mechanism 4 are provided in the groove 5.

[0036] In Embodiment 2, based on Embodiment 1, the fixing mechanism 2 includes a guide post 201 fixed within the groove 5. Below the guide post 201 is a bidirectional lead screw 204 rotatably connected within the groove 5. Two nuts 2012 are symmetrically threaded onto the outer side of the bidirectional lead screw 204. Two guide plates 202 are symmetrically and movably sleeved onto the outer side of the guide post 201. The two guide plates 202 are respectively fixed to the tops of the two nuts 2012. Two sliding rods 2011 are symmetrically and fixedly connected inside the groove 5. A sliding rod is movably sleeved between the two sliding rods 2011. Slide 209 is located below the bidirectional lead screw 204. Two movable rods 208 are symmetrically rotatably connected to the outer side of slide 209. The tops of the two movable rods 208 are rotatably connected to the bottoms of two lead nuts 2012. Two top rods 2010 are symmetrically fixedly connected to the top of slide 209. The guide post 201 and the two bidirectional lead screws 204 are located between the two top rods 2010. A base block 203 is fixedly connected to the bottom center of the electron tube die post 8. The bottom of the base block 203 extends into the groove 5, and the base block 203 is located in the guide... Above column 201, two bottom sleeves 2014 are symmetrically fixedly connected to the bottom of bottom block 203. The two bottom sleeves 2014 are located directly above the two top rods 2010, and the inner diameter of the two bottom sleeves 2014 is equal to the outer diameter of the two top rods 2010. Bottom block 203 is located between two guide plates 202. Bottom block 203 is provided with limiting holes 207. Limiting posts 2013 are fixedly connected to the sides of the two guide plates 202 that are close to each other. Both limiting posts 2013 are inserted into the limiting holes 207. The inside of the groove 5 is provided with an inner plate 2. 016, A support plate 2017 is fixedly connected between the bottom of the inner plate 2016 and the inner bottom wall of the groove 5. A drive shaft 206 is rotatably connected to the side of the inner plate 2016 near the slide plate 209. A handwheel 2018 is fixedly installed on the outside of the drive shaft 206. One end of the two-way lead screw 204 is fixedly connected to a side shaft 205 located above the drive shaft 206. A small gear 2015 is fixedly installed on the outside of the side shaft 205. A large gear 2019 is fixedly installed on the outside of the drive shaft 206. The large gear 2019 and the small gear 2015 are meshed and connected.

[0037] In the initial state, the bottom of the base block 203 extends into the groove 5, and both guide plates 202 are in contact with the base block 203. Both limiting posts 2013 are inserted into the limiting holes 207, fixing the base block 203 to the base 1 and improving tensile strength. When the handwheel 2018 is rotated, the drive shaft 206 rotates, which in turn rotates the large gear 2019. Since the large gear 2019 meshes with the small gear 2015, it drives the side shaft 205 to rotate, which in turn drives the bidirectional lead screw 204 to rotate. Then, through the two nuts 2012, the two guide plates 202 are driven to move along the guide posts 201... The two limiting posts 2013 move away from each other and disengage from the limiting hole 207. At the same time, the two movable rods 208 drive the slide plate 209 to slide upward along the two sliding rods 2011, and drive the two push rods 2010 to rise. When the two limiting posts 2013 are completely removed from the limiting hole 207, the two push rods 2010 are inserted into the two bottom sleeves 2014 respectively. Then, the handwheel 2018 is rotated to make the two push rods 2010 continue to rise, pushing the bottom block 203 upward, so that the electron tube cathode pin 7 disengages from the insertion hole 6, and finally the electron tube core cathode is led out.

[0038] In Example 3, based on Example 1, the protective mechanism 3 includes a protective plate 301 movably installed in the groove 5. The side of the protective plate 301 away from the handwheel 2018 is in contact with the inner plate 2016. The protective plate 301 has a through hole 306. A vertical plate 305 is fixedly installed inside the groove 5. The end of the drive shaft 206 away from the inner plate 2016 is rotatably connected to the vertical plate 305. The side shaft 205 passes through the vertical plate 305 and is rotatably connected to the vertical plate 305. One end of the guide post 201 is fixedly connected to the vertical plate 305. A side plate 302 located above the side shaft 205 is fixedly connected to the side of the protective plate 301 near the vertical plate 305. The side of the side plate 302 away from the protective plate 301 passes through the vertical plate 305 and is fixedly connected to a slider 303. The slider 303 is movably sleeved on the outside of the guide post 201. A spring 304 is fixedly connected between the slider 303 and the vertical plate 305. The spring 304 is sleeved on the outside of the guide post 201.

[0039] First, push the protective plate 301, which drives the slider 303 to slide along the guide post 201 via the side plate 302. At this time, the spring 304 is stretched, and the protective plate 301 separates from the inner plate 2016 until the handwheel 2018 passes through the through hole 306. At this time, the handwheel 2018 can be rotated to fix or loosen the bottom block 203. When the protective plate 301 is loosened, the protective plate 301 moves under the action of the spring force of the spring 304 until the protective plate 301 is in contact with the inner plate 2016, thus storing and protecting the handwheel 2018. Finally, it prevents the handwheel 2018 from rotating due to external force, ensuring that the electron tube cathode pin 7 is stably located in the socket 6 and improving tensile strength.

[0040] In Embodiment 4, based on Embodiment 1, the locking mechanism 4 includes a lifting plate 401 located above the side plate 302. A connecting frame 404 is fixedly connected to the side of the lifting plate 401 away from the vertical plate 305. A locking gear 405 is fixedly connected to the bottom of the connecting frame 404. The locking gear 405 meshes with a pinion 2015. Two L-shaped round rods 402 are symmetrically fixedly connected between the side of the vertical plate 305 near the protective plate 301 and the inner top wall of the groove 5. The lifting plate 401 is movably sleeved on the outside of the two L-shaped round rods 402. A drive rod 403 is rotatably connected to the side of the lifting plate 401 away from the vertical plate 305. The bottom end of the drive rod 403 is rotatably connected to the top of the side plate 302.

[0041] When the protective plate 301 is pushed, the slider 303 slides along the guide post 201 via the side plate 302. At this time, the spring 304 is stretched, and then the lifting plate 401 slides upward along the two L-shaped round rods 402 via the drive rod 403. The locking gear 405 rises and separates from the pinion 2015 via the connecting frame 404, releasing the restriction effect on the side shaft 205. At this time, the handwheel 2018 can be rotated to rotate the side shaft 205. When the protective plate 301 is released, the spring 304 returns to its original position, causing the slider 303 to slide along the guide post 201 and approach the upright plate 305. Then, the side plate 302 and the protective plate 301 slide. The lifting plate 401 slides downward along the two L-shaped round rods 402 via the drive rod 403. At the same time, the locking gear 405 descends and meshes with the pinion 2015 via the connecting frame 404. Finally, the side shaft 205 is limited, further ensuring the stable connection between the electron tube core 8 and the base 1.
