Description

Technical Field

[0001] This utility model relates to the field of sensor sintering base technology, and more specifically to a novel brazing sensor sintering base. Background Technology

[0002] A sensor is a detection device that can sense a measured quantity (such as temperature, pressure, light intensity, etc.) and convert it into a usable electrical signal or other form of output. It is a core component of automation and intelligent systems.

[0003] When using a sensor, it needs to be connected to a circuit. In this process, a special base is required. First, the sensor is fixed on the base, and then the sensor and the base are installed in the corresponding position in the circuit, such as a new type of brazed sensor sintering base with announcement number CN214666908U.

[0004] The existing sensor sintering base is a complete unit, with the sensor embedded in the groove of the base. If the sensor is tightly embedded in the groove, although it can effectively prevent problems such as displacement and shaking of the sensor during operation, it will bring great inconvenience to the subsequent disassembly and maintenance work, and will also easily cause wear to the sensor during disassembly, affecting its sensing accuracy and causing increased data deviation. If the two are not tightly embedded for the sake of convenient maintenance, it is very easy for the sensor to loosen and fall off the base, affecting the normal operation. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a novel brazed sensor sintering base, which can disassemble and separate the two ceramic semicircular seats that are fastened together so as to remove the sensor. This ensures that the sensor is tightly fixed and does not loosen in the use state, and can be disassembled for maintenance without damaging the sensor, which is very convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel brazed sensor sintering base, comprising two interlocking ceramic semicircular seats, which together form a complete circular ceramic base, wherein a mounting groove for embedding a sensor is provided at the center of the top of the ceramic base. The top of the ceramic semicircular base has two connecting grooves, which are located outside the mounting groove. The inner wall of the connecting groove has a connecting hole, the depth of which is greater than the depth of the connecting groove. When the two ceramic semicircular bases are fastened together, the two connecting grooves on one ceramic semicircular base are respectively connected to the two connecting grooves on the other ceramic semicircular base. Solder can be injected into the connecting groove and the connecting hole. A heat-conducting metal rod for facilitating the melting of solder is fixed on the inner wall of the connecting groove.

[0007] Furthermore, two elastic plates for reinforcing the sensor are fixedly provided on the inner wall of the mounting groove, and the two elastic plates are respectively located on two ceramic semi-circular seats.

[0008] Furthermore, each of the two ceramic semi-circular bases is fixed with two fixing claws at its top, one end of which extends to the inside of the mounting groove opening.

[0009] Furthermore, two support pads are fixedly provided at the bottom of each of the two ceramic semicircular seats to provide support. Two needles are fixedly provided at the bottom of one ceramic semicircular seat, and two conduits are fixedly provided at the bottom of the other ceramic semicircular seat. The outer ends of the needles and conduits are covered with rubber protective sleeves when not in use, and the rubber protective sleeves can be torn off before use.

[0010] Furthermore, semi-cylinders are fixedly provided on both sides of the ceramic semi-circular base. Two semi-cylinders on one ceramic semi-circular base are respectively engaged with two semi-cylinders on the other ceramic semi-circular base. The four semi-cylinders are engaged in pairs to form two cylinders, and a fixing sleeve is fitted on the outer end of each cylinder.

[0011] Furthermore, an elastic ring is fitted around the outer end of the circular ceramic base, and two limiting strips are fixedly provided at the outer ends of the two ceramic semicircular bases. The elastic ring is sandwiched between the two limiting strips to prevent slippage.

[0012] Furthermore, the top of the circular ceramic base is provided with a plastic dust cover when idle, and a rubber plug embedded in the mounting groove is fixedly provided at the bottom of the plastic dust cover.

[0013] The technical effects and advantages of this utility model are as follows: This invention combines two ceramic semicircular bases into a single circular ceramic base, with the sensor embedded in the mounting groove. The connecting grooves on the two ceramic semicircular bases are aligned in pairs, and solder is injected into the connecting grooves to connect the two ceramic semicircular bases. During maintenance, the solder can be remelted to separate the two ceramic semicircular bases, allowing the sensor to be removed. This method ensures that the sensor is tightly fixed in use and can be disassembled for maintenance without damaging the sensor, making it very convenient. Attached Figure Description

[0016] 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.

[0017] Refer to the instruction manual appendix Figures 1-5 This utility model provides a novel brazing sensor sintering base, including two interlocking ceramic semicircular seats 1, which together form a complete circular ceramic base. The top center of the ceramic base is provided with an installation groove 101 for embedding the sensor. Two elastic pieces 102 for reinforcing the sensor are fixedly provided on the inner wall of the mounting groove 101. The two elastic pieces 102 are respectively located on two ceramic semi-circular seats 1. Two fixing claws 103 are fixedly provided at the top of each of the two ceramic semi-circular seats 1. One end of the fixing claw 103 extends to the inner side of the opening of the mounting groove 101.

[0018] During the process of fastening the two ceramic semicircular bases 1 into a complete circular ceramic base, the sensor to be fixed is placed between the two ceramic semicircular bases 1. After the two ceramic semicircular bases 1 are fastened together, the sensor is naturally embedded in the mounting groove 101. The elastic piece 102 will also contact the sensor and use its own elasticity to buffer, preventing the inner wall of the mounting groove 101 from directly squeezing the sensor and causing damage to the sensor. In addition, after the two ceramic semicircular bases 1 are fastened together, the fixing claw 103 will also rest on the top of the sensor to limit the sensor from above and prevent the sensor from falling out of the mounting groove 101.

[0019] Before firmly fixing the two ceramic semicircular bases 1 into a single unit, a simple preliminary fixation is required, such as... Figure 1 , Figure 5 As shown, semi-cylinders 10 are fixed on both sides of the ceramic semi-circular base 1. Two semi-cylinders 10 on one ceramic semi-circular base 1 are respectively fastened to two semi-cylinders 10 on the other ceramic semi-circular base 1. The four semi-cylinders 10 are fastened to two cylinders in pairs. The outer ends of the two cylinders are fitted with fixing sleeves 5.

[0020] The outer end of the circular ceramic base is fitted with an elastic ring 4, and the outer ends of the two ceramic semicircular bases 1 are each fixed with two limiting strips 3. The elastic ring 4 is sandwiched between the two limiting strips 3 to prevent slippage.

[0021] After the two ceramic semicircular bases 1 are initially engaged, the four semicircular cylinders 10 are also engaged in pairs to form two cylinders. Then, the fixing sleeve 5 is placed on the outer end of the cylinder, thereby fixing the engaged semicircular cylinders 10 in the fixing sleeve 5, which also indirectly fixes the two ceramic semicircular bases 1. Furthermore, the semicircular cylinders 10 placed inside the fixing sleeve 5 can also play a positioning role, ensuring that the two ceramic semicircular bases 1 are accurately aligned and do not deviate. Then, the elastic ring 4 is placed on the outer end of the initially engaged circular ceramic base, and the limiting strip 3 is used to limit the elastic ring 4. At this time, the elastic ring 4 is in a taut state, and the elasticity of the elastic ring 4 can fix the two ceramic semicircular bases 1, further fixing the two ceramic semicircular bases 1 in the engaged state.

[0022] After the initial snap-fit, the two ceramic semicircular bases 1 still need to be connected into a whole, such as... Figure 1 , Figure 3 As shown, the top of the ceramic semicircular base 1 has two connecting grooves 2, which are located outside the mounting groove 101. The inner wall of the connecting groove 2 has a connecting hole 202, and the depth of the connecting hole 202 is greater than the depth of the connecting groove 2. When the two ceramic semicircular bases 1 are fastened together, the two connecting grooves 2 on one ceramic semicircular base 1 are respectively connected to the two connecting grooves 2 on the other ceramic semicircular base 1. Solder can be injected into the connecting groove 2 and the connecting hole 202. A heat-conducting metal rod 201 for facilitating the melting of solder is fixed on the inner wall of the connecting groove 2.

[0023] After the two ceramic semicircular seats 1 are snapped together and initially fixed, the four connecting slots 2 are also connected in pairs. At this time, molten solder is injected into the connected slots 2 in the connected state. The solder enters the connected slots 2 and the connecting holes 202, roughly filling them. Since the two connected slots 2 are interconnected at this time, the solder enters both connected slots 2 simultaneously and comes into contact with the two ceramic semicircular seats 1 at the same time. After the solder cools and solidifies, the two ceramic semicircular seats 1 can be fixed as a whole. The two ceramic semicircular seats 1 are connected and fixed by brazing. The connecting holes 202 can then... The depth of the connecting groove 2 can be further increased to make the connection between the solder and the ceramic semi-circular seat 1 tighter. By connecting the two ceramic semi-circular seats 1 in this way, when the sensor needs to be inspected and maintained, the solder in the connecting groove 2 can be reheated to melt it, or the heat-conducting metal rod 201 can be heated to conduct heat to the solder and melt it. After the solder melts, the two ceramic semi-circular seats 1 can be separated, and the sensor can be taken out for inspection and maintenance. This method ensures that the sensor is tightly fixed and does not loosen when in use, and can be disassembled for inspection and maintenance without damaging the sensor, which is very convenient.

[0024] When not in use, it is necessary to prevent dust and impurities from entering the connection slot 2 and the mounting slot 101, such as... Figure 4 , Figure 5 As shown, the top of the circular ceramic base is provided with a plastic dust cover 9 when it is not in use, and a rubber plug 901 is fixedly provided at the bottom of the plastic dust cover 9 and embedded in the mounting groove 101.

[0025] When not in use, the unused circular ceramic base has two ceramic semicircular bases 1 initially engaged, and a rubber plug 901 is filled inside the mounting groove 101. The plastic dust cover 9 connected to the top of the rubber plug 901 covers the mounting groove 101 and the connecting groove 2 at the top of the ceramic semicircular base 1, effectively preventing dust and impurities from entering the mounting groove 101 and the connecting groove 2. When in use, the rubber plug 901 can be removed.

[0026] Two support pads 104 are fixedly provided at the bottom of each of the two ceramic semicircular bases 1 to provide support. Two needles 6 are fixedly provided at the bottom of one ceramic semicircular base 1, and two conduits 7 are fixedly provided at the bottom of the other ceramic semicircular base 1. When not in use, the outer ends of the needles 6 and the conduits 7 are covered with rubber protective sleeves 8, which protect the needles 6 and the conduits 7. The rubber protective sleeves 8 can be removed before use.

[0027] When in use, peel off the rubber protective sleeve 8 at the outer end of the lead pin 6 and the conduit 7, connect the sensor to the circuit through the lead pin 6, and the conduit 7 is connected to the target being detected. For example, the hydraulic sensor detects hydraulic pressure through the conduit 7, and the air pressure sensor transmits air pressure through the conduit 7. The support pad 104 supports the ceramic semi-circular base 1 after installation, so that there is a certain space below it for heat dissipation.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
