Description

Technical Field

[0001] This utility model relates to the field of sensor housing technology, specifically a housing for a high-precision sensor. Background Technology

[0002] Thermocouple sensors work on the Seebeck effect, which states that when two metals are at contact, the different rates of electron diffusion at the contact point lead to charge accumulation and the formation of a thermoelectric potential. The greater the temperature difference, the higher the potential value. Thermocouple sensors are widely used in high-temperature furnaces and heat treatment equipment in industrial production, and are also commonly used in temperature monitoring in energy, chemical, and metallurgical industries. Thermocouple sensors have a wide measurement range, fast response speed, simple structure, and low cost.

[0003] According to the search, Chinese patent document, publication number CN218600714U, discloses a sensor housing that facilitates the replacement of components on the circuit board during debugging, while also ensuring the safety of other components. It includes a frame-type housing and two cover plates. The inner sides of the two cover plates are respectively provided with contoured protrusions that mate with the opening of the housing. The two long side walls inside the housing are respectively provided with bosses supporting the circuit board, and the two short side walls inside the housing are respectively provided with pins.

[0004] The aforementioned device splits the housing into a housing frame and two cover plates. First, the circuit board is installed inside the housing frame and multiple pins are soldered. Then, the internal circuit board is tested before the cover plates are soldered to allow for timely replacement of faulty components before cover plate installation. The cover plates are then soldered only after confirmation that everything is correct. Although this structure can reduce defective products through pre-testing, the high temperature generated during cover plate soldering can easily cause the soldered pins to have poor solder joints or detach. At the same time, if the internal circuit board fails again after the cover plates are soldered, disassembly and repair require breaking the soldered structure, which can easily damage the sensor housing. In view of this, we provide a housing for a high-precision sensor. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a housing for a high-precision sensor.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a housing for a high-precision sensor, including a frame, with multiple cover plates at both ends of the frame, and multiple positioning plugs added to the bottom surface of the cover plates. A warped clip is added to one side of the outer wall of each of the multiple positioning plugs, and the positioning plugs and the warped clips are located on both sides inside the frame. Multiple slots are opened on both sides inside the frame, and a guide rail is added to one side of the inner wall of the slots.

[0007] As described above, multiple pins are fixedly connected to both sides of the outer wall of the frame, and one end of each of the multiple pins extends to a pole, and the multiple poles are respectively located on both sides of the inner cavity of the frame.

[0008] As mentioned above, a mounting partition is added to the center of the inner wall of the frame, and the top surface of the mounting partition has multiple threaded holes.

[0009] As mentioned above, the height of the mounting partition is lower than the height of the extreme point, and multiple corner bracing plates are added between the bottom surface of the mounting partition and the inner wall of the frame.

[0010] As described above, the outer wall of the guide rail penetrates the center of the positioning plug-in, and the outer wall of the guide rail is slidably connected to the center of the positioning plug-in.

[0011] The aforementioned warped clip is integrally machined from metal material and has a certain elastic deformation capability.

[0012] As described above, the warped clip is embedded inside the slot, and one end of the warped clip is tightly fitted against the inner wall of the slot.

[0013] Compared with existing technologies, the housing of this high-precision sensor has the following advantages:

[0014] 1. After the circuit board is installed on the mounting plate with bolts and multiple pins are soldered to the pins of the circuit board, the circuit board inside the frame can be tested. After confirming that the circuit board is normal, the positioning plug on the surface of the cover plate is aligned with the slot on the top surface of the frame and inserted to install the cover plate and the frame. This effectively avoids problems such as poor soldering and desoldering caused by high temperature.

[0015] Second, this utility model, through the cooperation of the warp clip and the slot, allows the cover plate to be removed by simply pressing the warp clip inward to release the obstruction during subsequent maintenance, without damaging the original structure of the frame or cover plate, thus avoiding damage to the sensor housing caused by disassembling the cover plate during maintenance.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: a housing for a high-precision sensor, including a frame 1, with multiple cover plates 2 at both ends of the frame 1, and multiple positioning plugs 201 added to the bottom surface of the cover plates 2, with a warped clip 202 added to one side of the outer wall of each of the multiple positioning plugs 201, and the positioning plugs 201 and the warped clips 202 located on both sides inside the frame 1, with multiple slots 101 opened on both sides inside the frame 1, and a guide rail 102 added to one side of the inner wall of the slots 101.

[0026] After the circuit board is installed on the mounting partition 104 with bolts and multiple pins 103 are soldered to the pins 103 of the circuit board, the circuit board inside the frame 1 can be tested. After confirming that the circuit board is normal, the positioning plug 201 on the surface of the cover plate 2 is aligned with the slot 101 on the top surface of the frame 1 and inserted to install the cover plate 2 and the frame 1.

[0027] like Figure 2 As shown, multiple pins 103 are fixedly connected to both sides of the outer wall of the frame 1, and each of the multiple pins 103 has a pole 1031 extending from one end. The multiple poles 1031 are located on both sides of the inner cavity of the frame 1.

[0028] The Pole 1031 is built into the inner cavity of the frame 1 to avoid interference from the external environment to the connection point.

[0029] like Figure 2As shown, a mounting partition 104 is added to the center of the inner wall of the frame 1, and a plurality of threaded holes 1041 are opened on the top surface of the mounting partition 104.

[0030] Installing partition 104 divides the interior of frame 1 into two independent cavities to prevent interference between different modules.

[0031] like Figure 4 As shown, the mounting partition 104 is set at a height lower than the height of the pole 1031, and multiple corner bracing plates 1042 are added between the bottom surface of the mounting partition 104 and the inner wall of the frame 1.

[0032] The gusset plate 1042 can enhance the support strength of the mounting partition 104 and improve the load-bearing capacity of heavy components.

[0033] like Figure 4-5 As shown, the outer wall of the guide rail 102 penetrates the center of the positioning plug 201, and the outer wall of the guide rail 102 is slidably connected to the center of the positioning plug 201.

[0034] The guide rail 102 passes through the positioning plug 201, providing vertical constraint for the cover plate 2 and avoiding the offset and jamming problems that are easy to occur during manual assembly.

[0035] like Figure 3 As shown, the warped clip 202 is integrally machined from metal material, and the warped clip 202 has a certain elastic deformation capability.

[0036] The warped clip 202 has good elastic deformation properties, ensuring stable support with the inner wall of the slot 101 when engaged, and allowing the warped clip 202 to maintain its shape recovery ability after multiple disassemblies and reassemblies.

[0037] like Figure 4 As shown, the warped clip 202 is embedded inside the slot 101, and one end of the warped clip 202 is tightly fitted against the inner wall of the slot 101.

[0038] The structure of the warp clip 202 embedded in the slot 101 makes the engaging part of the warp clip 202 completely hidden inside the slot 101, avoiding accidental disengagement caused by external collisions.

[0039] It should be noted that: the inner wall of the slot 101 extends through the outer side of the frame 1, allowing the operator to directly push the warped piece 202 inside the frame 1 through the opening of the slot 101 on the outer side of the frame 1, so that the warped piece 202, which was originally pressed against the inner wall of the slot 101, deforms and detaches from the inner wall of the slot 101, so that the cover plate 2 can be smoothly pulled out.

[0040] Working principle: First, the sensor circuit board is fixed through the threaded hole 1041 on the top surface of the mounting partition 104. Then, the circuit board is soldered to the pole 1031 inside the frame 1. Next, the cover plate 2 is pushed along the guide rails 102 on both sides of the frame 1. As the cover plate 2 moves, the warped clip 202 on the outer wall of the positioning plug 201 deforms and temporarily contracts due to the pressure of the inner wall of the top of the slot 101. When fully pushed in, the warped clip 202 springs back open and abuts against the inner wall of the slot 101, realizing the mechanical locking of the cover plate 2 and the frame 1. During operation, the external device receives the detection signal transmitted by the circuit board through the pin 103. If maintenance is required, simply press the warped clip 202 to release the abutment, and the cover plate 2 can slide out along the guide rail 102.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
