Description

Technical Field

[0001] This utility model relates to the field of aerospace equipment technology, specifically to an integrated magnetometer circuit box that is small in size and lightweight. Background Technology

[0002] A magnetometer is a precision instrument used to measure the strength and direction of a magnetic field, and it is widely used in aerospace, geological exploration, industrial non-destructive testing, and consumer electronics. Its core functions rely on internal sensing probes and signal processing circuits. These electronic components are usually integrated on the same circuit board and packaged in a protective circuit box, forming an integrated magnetometer circuit box, which provides mechanical support, physical protection, and electromagnetic shielding for the internal components.

[0003] With technological advancements, the industry has placed increasingly stringent demands on the miniaturization, weight reduction, and high reliability of magnetometers, leading to the widespread adoption of integrated magnetometer circuit boxes that are small in size and lightweight. However, existing circuit board mounting methods in these boxes still have significant shortcomings: most are secured inside the box with multiple screws, and some even employ a non-removable integrated design. When a circuit board subsequently malfunctions and requires repair or replacement, specialized tools are needed for disassembly, or the entire circuit box must be disassembled, making the process cumbersome and complex, severely reducing the convenience and efficiency of circuit board maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a small-sized and lightweight integrated magnetometer circuit box to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a small-sized and lightweight integrated magnetometer circuit box, comprising:

[0006] The magnetometer base has a top cover at its top, and four first locking screws pass through the top of the top cover and are fixedly connected to the magnetometer base through the first locking screws. Three individual probes are arranged on one side inside the magnetometer base, and a circuit board is slidably arranged on the other side inside the magnetometer base. An electrical connector is soldered to the top of the circuit board.

[0007] The fixing component includes a connecting plate, a connecting seat rotatably provided at the middle of the top of the connecting plate, a vertical rod fixedly provided at the top of the connecting seat, a spring sleeved at the bottom of the outer wall of the vertical rod, elastic blocks fixedly provided on both sides of the outer wall of the vertical rod, a fixing sleeve being engaged together on the outer walls of the two elastic blocks, and a pressing frame fixedly provided on the outer wall of the fixing sleeve, with the bottom end of the pressing frame contacting the top of the circuit board.

[0008] Preferably, the magnetometer base has three adjacent sides on its outer wall that are provided with second locking screws, which are used to fix the magnetometer base to the individual probe.

[0009] Preferably, the fixing component further includes a limiting block, the bottom end of which is fixedly disposed at the top end of the vertical rod, and the top end of the limiting block and the top end of the magnetometer base are located on the same horizontal plane.

[0010] Preferably, the fixing component further includes two placement rods, one end of each placement rod being fixedly disposed at both ends of one side of the connecting plate.

[0011] Preferably, the top end of the spring is fixedly connected to the bottom end of the fixed sleeve, and the bottom end of the spring is fixedly connected to the top end of the connecting seat.

Detailed Implementation

[0023] 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.

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a small and lightweight integrated magnetometer circuit box, comprising:

[0026] The magnetometer base 11 has a top cover 12 at its top. Four first locking screws 121 pass through the top of the top cover 12 and are fixedly connected to the magnetometer base 11 through the first locking screws 121. Three individual probes 13 are provided on one side inside the magnetometer base 11. A circuit board 14 is slidably provided on the other side inside the magnetometer base 11. An electrical connector 15 is soldered to the top of the circuit board 14.

[0027] The fixing component includes a connecting plate 21, a connecting seat 22 is rotatably provided at the middle of the top of the connecting plate 21, a vertical rod 23 is fixedly provided at the top of the connecting seat 22, a spring 24 is sleeved at the bottom of the outer wall of the vertical rod 23, elastic blocks 25 are fixedly provided on both sides of the outer wall of the vertical rod 23, a fixing sleeve 26 is engaged together on the outer walls of the two elastic blocks 25, a pressing frame 27 is fixedly provided on the outer wall of the fixing sleeve 26, and the bottom end of the pressing frame 27 contacts the top of the circuit board 14;

[0028] The magnetometer base 11 provides the mounting reference and housing space for all internal components. Both the magnetometer base 11 and the top cover 12 are made of high-strength carbon fiber composite material, balancing weight reduction and structural strength. The top cover 12 and the magnetometer base 11 form a closed cavity, which serves to prevent dust and moisture and slightly shield external stray magnetic fields. The four first locking screws 121 are threaded into the top cover 12 and are evenly distributed, so that the top cover 12 is subjected to balanced force. The three individual probes 13 are used to correspond to the X, Y, and Z three-dimensional directions of the magnetic field, respectively, to achieve accurate detection of magnetic field strength and direction. The circuit board 14 integrates the magnetometer's drive circuit, signal amplification circuit, etc. The filter circuit, etc., is used to receive the raw signal from the single probe 13 and process and convert it. The electrical connector 15 is used to realize the electrical connection between the circuit board 14 and the external device. The outer wall of the electrical connector 15 is engaged with one end of the inner wall of the magnetometer base 11. The outer wall of the fixing sleeve 26 has two locking holes that are adapted to the elastic block 25. When the elastic block 52 is engaged with the fixing sleeve 26, the spring 24 is in a compressed state. The inner wall of the fixing sleeve 26 is slidably set on the outer wall of the vertical rod 23. The clamping frame 27 is U-shaped, which not only increases the contact area with the circuit board 14 and makes the pressure evenly distributed, but also avoids blocking the electronic components on the circuit board 14.

[0029] The magnetometer base 11 has three adjacent sides on its outer wall that are provided with second locking screws 111, and is fixedly connected to the single probe 13 through the second locking screws 111.

[0030] The second locking screw 111 is used to limit and fix the individual probe 13.

[0031] The fixing component also includes a limiting block 28, the bottom end of which is fixedly set at the top end of the vertical rod 23, and the top end of the limiting block 28 is on the same horizontal plane as the top end of the magnetometer base 11.

[0032] The limiting block 28 is used to limit the maximum upward sliding stroke of the fixing sleeve 26, preventing the fixing sleeve 26 from detaching from the top of the vertical rod 23. At the same time, the design of being flush with the top of the magnetometer base 11 ensures the compactness of the internal space of the circuit box, meeting the requirements of lightweight and integrated design. When the fixing sleeve 26 contacts the limiting block 28, the bottom of the clamping frame 27 is higher than the top of the magnetometer base 11, and the spring 24 is in a slightly compressed state.

[0033] The fixing component also includes two placement rods 210, one end of each placement rod 210 being fixedly mounted at both ends of one side of the connecting plate 21;

[0034] The placement rod 210 and the clamping frame 27 cooperate to form a clamping structure for the circuit board 14.

[0035] The top end of the spring 24 is fixedly connected to the bottom end of the fixed sleeve 26, and the bottom end of the spring 24 is fixedly connected to the top end of the connecting seat 22.

[0036] Rubber pads 29 are glued to the opposite side of the clamping frame 27 and the two placement rods 210;

[0037] The rubber pad 29 is in direct contact with the upper and lower ends of the circuit board 14, and the elasticity of the rubber buffers the vibration and impact.

[0038] Working principle: When the circuit board 14 inside the small and lightweight integrated magnetometer circuit box malfunctions, after opening the top cover 12 of the circuit box, press the two elastic blocks 25 inward. Under the elastic deformation of the spring 24, the fixing sleeve 26 moves upward. The upward movement of the fixing sleeve 26 moves the clamping frame 27 upward until the top of the fixing sleeve 26 contacts the bottom of the limit block 28. Then, rotate the vertical rod 23. The rotation of the vertical rod 23 drives the clamping frame 27 to rotate outward until the clamping frame 27 rotates outward 180 degrees. Then, move the electrical connector 15 upward. Through the electrical connector 15, the circuit board 14 moves outward and separates from the magnetometer base 11. This method facilitates the disassembly, repair and replacement of the circuit board 14. The whole process is time-saving and labor-saving, and the operation is simple and convenient, greatly improving the convenience and efficiency of the maintenance of the circuit board 14.

[0039] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0040] It also includes a reference component, which includes reference rods 31 fixed on both sides of the top of the connecting plate 21. One of the reference rods 31 has a contact rod 32 on its outer wall, and one end of the contact rod 32 is fixedly connected to the outer wall of the fixing sleeve 26.

[0041] The reference rod 31 is used to provide a precise positioning reference and to provide a reference for the contact engagement of the contact rod 32. When the contact rod 32 rotates to contact another reference rod 31, the contact rod 32 rotates 180 degrees.

[0042] Working principle: When the vertical rod 23 rotates, it drives the fixed sleeve 26 to rotate. The rotation of the fixed sleeve 26 also drives the contact rod 32 to rotate. When the contact rod 32 rotates to contact another reference rod 31, the fixed sleeve 26 drives the clamping frame 27 to rotate 180 degrees, which facilitates the outward movement and removal of the circuit board 14. Conversely, the fixed sleeve 26 can drive the clamping frame 27 to rotate 180 degrees in reverse, so that the clamping frame 27 can quickly rotate to the top of the circuit board 14 for reset, which facilitates the subsequent clamping and fixing of the circuit board 14 and improves the overall structural positioning stability.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
