Description

Technical Field

[0001] This utility model relates to the field of high-frequency circuit ceramic substrate technology, specifically to a corrosion-resistant high-frequency circuit ceramic substrate. Background Technology

[0002] Ceramic substrates are special boards made by directly bonding copper foil to the surface (single-sided or double-sided) of an alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperatures. The resulting ultra-thin composite substrates possess excellent electrical insulation properties, high thermal conductivity, excellent solderability, and high adhesion strength. Like PCB boards, they can be etched with various patterns and have a large current-carrying capacity. Therefore, ceramic substrates have become a fundamental material for high-power power electronic circuit structure and interconnection technologies.

[0003] Most existing high-frequency circuit ceramic substrates are fixed and installed using adhesives, which makes it inconvenient to quickly disassemble and repair or replace them when they malfunction, resulting in poor usability. To address this issue, we propose a corrosion-resistant high-frequency circuit ceramic substrate. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant high-frequency circuit ceramic substrate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant high-frequency circuit ceramic substrate, comprising:

[0006] A ceramic substrate body has fixing seats at both ends. Each fixing seat has a sliding groove, within which a clamping plate is slidably connected. A groove is formed on one side of the fixing seat near the sliding groove, with a through groove on the inner wall of one end of the groove communicating with the sliding groove. A slider is slidably connected within the groove, and a locking block is fixedly adhered to one side wall of the slider. A locking groove is formed on the side wall of the clamping plate near the groove, and the locking block is movably inserted into the locking groove. A first semi-circular stud is fixedly adhered to the top wall of the fixing seat, and a second semi-circular stud is fixedly adhered to the top wall of the slider. The first and second semi-circular studs are in contact with each other, and screw sleeves are threaded onto both the first and second semi-circular studs.

[0007] Preferably, the outer wall of the fixing seat has an opening that communicates with the groove, and a limiting block is slidably connected in the opening, the limiting block being fixedly bonded to the slider.

[0008] Preferably, a fixing block is fixedly bonded to the top wall of the clamping plate, and a slot is formed on the top wall of the fixing block.

[0009] Preferably, positioning grooves are provided on both sides of the ceramic substrate body, and positioning blocks are fixedly bonded to the inner wall of the fixing seat, with the positioning blocks being movably inserted into the positioning grooves.

[0010] Preferably, the ceramic substrate body is an alumina ceramic substrate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, the two fixing seats are first fixedly installed in the required positions, and then the ceramic substrate body is placed between the two fixing seats. Then, the clamping plate is pushed so that it slides in the groove and clamps onto the ceramic substrate body. Then, the slider drives the locking block to insert into the locking groove to limit the clamping plate. Finally, the screw sleeve is screwed onto the first and second semi-circular studs to lock the slider. This realizes the convenient disassembly and assembly of the ceramic substrate body, so that it can be quickly repaired or replaced when the ceramic substrate body fails. Attached Figure Description

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.

[0018] Please see Figure 1-3This utility model provides a technical solution: a corrosion-resistant high-frequency circuit ceramic substrate, comprising:

[0019] A ceramic substrate body 1 has a fixing seat 2 at both ends. The fixing seat 2 has a sliding groove 3, and a clamping plate 4 is slidably connected in the sliding groove 3. The fixing seat 2 has a groove 5 on one side of the sliding groove 3. A through groove is formed on the inner wall of one end of the groove 5, and the through groove of the groove 5 communicates with the sliding groove 3. A slider 6 is slidably connected in the groove 5. A locking block 7 is fixedly bonded to one side wall of the slider 6. A locking groove 8 is formed on the side wall of the clamping plate 4 near the groove 5. The locking block 7 is movably inserted into the locking groove 8. A first semi-circular stud 9 is fixedly bonded to the top wall of the fixing seat 2. A second semi-circular stud 10 is fixedly bonded to the top wall of the slider 6. The first semi-circular stud 9 and the second semi-circular stud 10 are in contact with each other. A screw sleeve 11 is threadedly connected to the first semi-circular stud 9 and the second semi-circular stud 10.

The limiting block 13 is fixedly bonded to the slider 6. By the sliding cooperation between the limiting block 13 and the opening 12, the slider 6 can be easily limited in the groove 5, preventing the slider 6 from falling out of the groove 5.

[0021] A fixing block 14 is fixedly bonded to the top wall of the clamping plate 4. A latching groove 15 is provided on the top wall of the fixing block 14. The latching groove 15 facilitates the latching block 14 to be pulled out, thus facilitating the clamping plate 4 to be pulled out.

[0022] Positioning grooves 16 are provided on both sides of the ceramic substrate body 1. Positioning blocks 17 are fixedly bonded to the inner wall of the fixing base 2. The positioning blocks 17 are movably inserted into the positioning grooves 16 to facilitate positioning of the ceramic substrate body 1 during installation.

[0023] The ceramic substrate body 1 is an alumina ceramic substrate, which has high chemical stability and can resist corrosion from acids, alkalis and salts, thus improving corrosion resistance.

[0024] Working principle: When using this utility model, firstly, two fixing seats 2 are fixedly installed in the required positions, then the ceramic substrate body 1 is placed between the two fixing seats 2. Then, push the clamping plate 4 so that the clamping plate 4 slides in the slide groove 3 and clamps onto the ceramic substrate body 1. Then, the slider 6 drives the locking block 7 to be inserted into the locking groove 8 to limit the clamping plate 4. Then, tighten the screw sleeve 11 onto the first semi-circular stud 9 and the second semi-circular stud 10 to lock the slider 6. This realizes the convenient disassembly and assembly of the ceramic substrate body 1, so that when the ceramic substrate body 1 fails, it can be quickly repaired or replaced.
