Description

Technical Field

[0001] This invention belongs to the field of electronic components technology, and in particular relates to a button assembly with integrated sensing function. Background Technology

[0002] In the prior art, the button assemblies with integrated sensing functions applicable to fields such as electronics, aviation, aerospace, and shipbuilding need to realize signal transmission and signal shielding between the sensor substrate and the cable assembly; some sensors need to be installed in the inner hole of the hexagonal screw, where space is extremely limited, and the function of disassembly and separation is required, so a solderless interconnection method is needed.

[0003] CN207098212U designs a snap-fit ​​BNC radio frequency triaxial connector, which adopts a structure consisting of an outer conductor, an inner conductor, and an insulator. The outer conductor does not transmit signals and is used to shield external interference. The three-snap-fit ​​connection method enables fast and reliable insertion and removal, enhancing anti-interference capabilities.

[0004] CN218732098U designs a detachable button-type RF coaxial connector including an installation mechanism and a limiting mechanism. The connector achieves convenient installation and limiting through components such as a positioning block, a fixing ring, a spring, a connecting rod, and a moving ring. The installation mechanism secures the connector through the cooperation of the spring and the connecting rod, while the limiting mechanism prevents malfunction of the moving ring through the cooperation of the spring and the pull rod, ensuring a stable connection.

[0005] However, the above two designs have complex structures and large sizes, which cannot meet the application requirements.

[0006] CN114039251A designs an RF coaxial button adapter. Through a combination of an inner conductor, outer conductor, insulating support medium, button, and probe conductor, it achieves contact interconnection between modules without microstrip soldering. RF signal transmission is achieved using axial elastic contact and radial clamping force. This design meets space requirements; however, as a coaxial connector, it lacks adequate shielding and relies solely on insertion and extraction force for fixation, posing a certain risk to its stability under vibration and shock conditions.

[0007] Therefore, there is a need to invent a detachable, well-shielded, and well-fixed button assembly with integrated sensing functions for use in confined spaces. Summary of the Invention

[0008] To address the problems in the prior art, the present invention proposes the following technical solution: A bobbin thread assembly with integrated sensing function, used in conjunction with an internal hexagonal screw, wherein the internal hexagonal screw has an inner groove, the bobbin thread assembly includes... A socket is assembled at the bottom of the inner groove. The socket includes an outer conductor, a base plate, and a sensor. The outer conductor has an axially distributed and through mounting cavity 1 and a mounting cavity 2. The base plate and the sensor are both welded and assembled in the mounting cavity 2. The base plate is provided with contacts. The insertion end of the outer conductor has a gap A with the inner groove, and the outer ring of the insertion end of the outer conductor has an external thread structure. A plug that is connected to a socket, the plug including a snap button assembly and an outer conductor two sleeved outside the snap button assembly, the plug end of the outer conductor two having a gap B between it and the snap button assembly, and the inner ring of the plug end of the outer conductor two having an internal thread structure. When the socket and plug are connected, the outer conductor 2 is inserted into gap A, the outer conductor 1 is inserted into gap B, and the plug end of the button assembly is inserted into the mounting cavity 1 and contacts the contact point on the substrate. The outer conductor 2 is controlled to rotate until the internal thread structure and the external thread structure are threadedly engaged. At this time, the button assembly is confined inside the outer conductor 2 and stably connected with the socket.

[0009] As a preferred embodiment of the above technical solution, the button assembly includes a dielectric body, on which a limiting step one is distributed around the dielectric body, and on which a limiting step two is distributed around the outer conductor two. After the outer conductor two is threadedly connected to the outer conductor one, the protective cap abuts against the substrate to limit the insertion end of the button assembly, and the limiting step one and the limiting step two abut against the tail end of the button assembly to limit the insertion end.

[0010] As a preferred embodiment of the above technical solution, the button assembly further includes a protective cap, a button, a solder cup, and a cable, which are assembled inside the dielectric body and connected in sequence at their ends. The plug end of the protective cap extends axially to the outside of the dielectric body, and the tail end of the cable extends axially to the outside of the second outer conductor. The combination structure of the protective cap, the button, the solder cup, and the cable is provided in three sets, and the substrate is provided with two signal contacts and one grounding contact.

[0011] As a preferred embodiment of the above technical solution, the diameter of the first mounting cavity is smaller than the diameter of the second mounting cavity, and a limiting step three is formed at the connection between the first mounting cavity and the second mounting cavity; When the socket is installed inside the inner groove, the end face of the substrate abuts against the limiting step, and the end face of the sensor abuts against the bottom wall of the inner groove.

[0012] As a preferred embodiment of the above technical solution, the substrate and the sensor are provided with a first protrusion, and the inner wall of the second mounting cavity is provided with a second protrusion groove that matches the first protrusion.

[0013] As a preferred embodiment of the above technical solution, the outer conductor is provided with a milled edge that matches the inner groove.

[0014] As a preferred embodiment of the above technical solution, a convex groove is provided on the side wall of the mounting cavity, and a convex bulge matching the convex groove is provided on the medium body.

[0015] As a preferred embodiment of the above technical solution, the outer wall of the second outer conductor is provided with a milled edge.

[0016] The beneficial effects of this invention are as follows: This technical solution presents a button-type assembly with integrated sensing function. In the socket, a substrate is housed within an outer conductor, and a sensor is welded and assembled inside a mounting cavity. By reducing the impact of the socket's mating height and miniaturizing the socket's proportion of the inner space, the miniaturization requirement of the button-type assembly is achieved. When the socket and plug are engaged, the outer conductor 2 is inserted into gap A, and the outer conductor 1 is inserted into gap B, forming a shielding layer. This provides excellent shielding performance for the button-type assembly with integrated sensing function. The plug-in end of the button-type assembly contacts the contacts on the substrate within the mounting cavity, ensuring reliable signal transmission. After the socket and plug are engaged, the outer conductor 2 is rotated until the internal and external threads engage. This threaded locking ensures the stability of the engagement between the socket and plug, solving the problem of insufficient holding force and unreliable contact in existing spring-loaded connectors after dozens of insertions and removals. This design is particularly suitable for vibration and shock environments.

[0017] This technical solution presents a button-type component with integrated sensing function. Sound waves are converted into electrical signals after passing through a sensor and a substrate. These electrical signals are then transmitted to the mainboard via the button-type component for amplification and processing of analog signals. In this embodiment, the button-type component with integrated sensing function can be installed into the inner groove of a hexagonal screw. The integrated sensing button-type component formed by the combination of a socket and a plug offers advantages such as solderless flexible interconnection, good shielding, high reliability, detachability, and miniaturization. It is suitable for applications in electronics, aviation, aerospace, and shipbuilding, and is particularly suitable for the installation of integrated sensing button-type components in confined spaces and for solderless, detachable analog signal transmission.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1 The present invention relates to a button assembly with integrated sensing function, which is assembled in the inner groove 21 of the internal hexagon screw 2. The internal hexagon screw 2 is a GB / T70.1 screw. Due to the tightening requirements of the internal hexagon screw 2 itself, the height of the socket 1 cannot be higher than the inner groove 21. Therefore, the socket 1 needs to be assembled at the bottom of the inner groove 21 to facilitate the torque tightening of it with an internal hexagon wrench. Traditional mating connectors cannot meet this requirement, which is very difficult in terms of spatial structure.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a hair button assembly with integrated sensing function is used in conjunction with an internal hex screw 2. The internal hex screw 2 has an inner groove 21. The hair button assembly includes... The socket 1 is assembled at the bottom of the inner groove 21. The socket 1 includes an outer conductor 11, a base plate 12 and a sensor 13. The sensor 13 is a sound sensor. The outer conductor 11 has an axially distributed and through mounting cavity 111 and a mounting cavity 212. The base plate 12 and the sensor 13 are both welded and assembled in the mounting cavity 212. The base plate 12 is provided with a contact point. The insertion end of the outer conductor 11 has a gap A with the inner groove 21, and the outer ring of the insertion end of the outer conductor 11 is provided with an external thread structure. The plug 3 is connected to the socket 1. The plug 3 includes a button assembly 31 and an outer conductor 32 sleeved on the outside of the button assembly 31. There is a gap B between the plug end of the outer conductor 32 and the button assembly 31, and the inner ring of the plug end of the outer conductor 32 is provided with an internal thread structure. In this embodiment, the outer conductor 11 and the outer conductor 32 are both made of brass or stainless steel. When the socket 1 and plug 3 are plugged in, the outer conductor 2 32 is inserted into gap A and the outer conductor 11 is inserted into gap B. The plug end of the button assembly 31 is inserted into the mounting cavity 111 and contacts the contact point on the substrate 12. The outer conductor 2 32 is controlled to rotate until the internal thread structure and the external thread structure are threadedly engaged. At this time, the button assembly 31 is confined inside the outer conductor 2 32 and stably plugged into the socket 1.

[0023] In this technical solution, a button assembly with integrated sensing function is provided. In the socket 1, a substrate 12 is set in the outer conductor 11 and a sensor 13 is welded and assembled inside the mounting cavity 112. By reducing the influence of the socket docking height, the height space ratio of the socket 1 in the inner groove 21 is reduced, thus achieving the miniaturization requirement of the button assembly. When the socket 1 and plug 3 are plugged in, the outer conductor 2 32 is inserted into gap A and the outer conductor 11 is inserted into gap B. The outer conductor 11 and the outer conductor 2 32 form a shielding layer, which makes the button assembly with integrated sensing function in this technical solution have good shielding performance. The plug end of the button assembly 31 is inserted into the mounting cavity 111 and contacts the contact point on the substrate 12 to realize reliable signal transmission. After the socket 1 and plug 3 are plugged in, the outer conductor 32 is rotated until the internal thread structure and the external thread structure are threaded together. The stability of the plugging and mating between the socket 1 and plug 3 is ensured by thread locking. This solves the problem of insufficient holding force and unreliable contact in the existing spring-type connector after dozens of plugging and unplugging cycles. It is especially suitable for vibration and shock environments. In this technical solution, an integrated sensing button assembly converts sound waves into electrical signals after passing through sensor 13 and substrate 12. The electrical signals are then transmitted to the mainboard via button assembly 31 for amplification and processing of analog signals. In this embodiment, the integrated sensing button assembly can be installed into the internal hexagonal slot of a GB / T70.1 screw. The integrated sensing button assembly formed by the cooperation of socket 1 and plug 3 has the requirements of solderless flexible interconnection, good shielding, high reliability, detachability, and miniaturization. It is suitable for fields such as electronics, aviation, aerospace, and shipbuilding, and is particularly suitable for the installation of integrated sensing button assemblies in confined spaces and the solderless detachable analog signal transmission.

[0024] How to achieve a stable plug-in connection between the button assembly 31, which is confined inside the outer conductor 32, and the socket 1; such as... Figure 9 As shown, the button assembly 31 includes a dielectric body 313, which can be made of engineering plastics that meet performance requirements, such as PEEK, PI, etc. Limiting steps 3132 are distributed around the dielectric body 313, and limiting steps 321 are distributed around the outer conductor 32. After the outer conductor 32 is threadedly connected to the outer conductor 11, the protective cap 311 abuts against the substrate 12 to limit the insertion end of the button assembly 31. The limiting steps 3132 and 321 abut against the tail end of the button assembly 31 to limit the tail end of the button assembly 31, preventing the button assembly 31 from coming off the outer conductor 32 after locking.

[0025] like Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, the button assembly 31 also includes a protective cap 311, a button 312, a solder cup 314, and a cable 315, which are assembled inside the medium body 313 and connected sequentially at their ends. More specifically, the button 312 is an elastic, compressible material made of uniformly braided copper wire with a gold-plated surface. The solder cup 314 is made of brass and is fixed inside the medium body 313 by barbs. The two ends of the solder cup 314 are respectively assembled with the button 312 and the cable 315 by welding. The protective cap 311 and the button 312 can move axially relative to the medium body 313. The insertion end of the protective cap 311 is axial. Extending to the outside of the dielectric body 313, when the socket 1 and plug 3 are plugged in, the protective cap 311 contacts the solder pad of the substrate 12. The button 312 achieves the function of elastic solderlessness. When compressed, it provides positive pressure to the protective cap and transmits it to the solder pad, realizing reliable signal transmission. The tail end of the cable 315 extends axially to the outside of the outer conductor 32 and can be connected to a standard coaxial or triaxial connector for interconnection with the device. In this embodiment, the combination structure of the protective cap 311, button 312, solder cup 314 and cable 315 is provided in three sets. The substrate 12 is provided with two signal contacts and one ground contact.

[0026] To achieve stable assembly of socket 1, firstly, to achieve stable assembly of substrate 12 and sensor 13 inside mounting cavity 112, such as... Figure 5 As shown, the diameter of mounting cavity 111 is smaller than the diameter of mounting cavity 112, and a limiting step 3 is formed at the connection between mounting cavity 111 and mounting cavity 112. When the socket 1 is assembled inside the inner groove 21, the end face of the substrate 12 abuts against the limiting step 3, and the grounding pad of the substrate 12 is fixed by welding after being limited by the limiting step 3. The end face of the sensor 13 abuts against the bottom wall of the inner groove 21 and is fixed by welding. At the same time, the grounding pad of the substrate 12 needs to be fixed by welding after being limited by the limiting step 3 of the outer conductor 11, and the sensor 13 also needs to be fixed by welding to the substrate 12, which further reduces the height space ratio of the socket 1 in the inner groove 21.

[0027] Secondly, such as Figure 7 As shown, the substrate 12 and sensor 13 are provided with a first protrusion 14, and the inner wall of the second mounting cavity 112 is provided with a second protrusion groove 1121 that matches the first protrusion 14. When the substrate 12 and sensor 13 are assembled in the second mounting cavity 112, the first protrusion 14 is located inside the second protrusion groove 1121. When the substrate 12 and sensor 13 are installed, the substrate 12 and sensor 13 and the outer conductor 11 are limited by the protrusion to ensure that the position direction of the points during the installation process is correct, thus ensuring the accuracy of the assembly.

[0028] Again, such as Figure 3 , Figure 4 , Figure 5 As shown, the outer conductor 11 is provided with a milled edge 15 that matches the inner groove 21; when the socket 1 is assembled in the inner groove 21, the milled edge 15 matches the inner groove 21, so that the socket 1 has an anti-rotation function when it is in the inner groove 21, ensuring the stability of the position of the socket 1.

[0029] like Figure 6 , Figure 9 , Figure 10 As shown, a convex groove 1111 is provided on the side wall of the mounting cavity 111, and a convex second 3131 matching the convex groove 1111 is provided on the medium body 313. When the socket 1 and the plug 3 are plugged in, the convex second 3131 in the plug 3 is inserted into the convex groove 1111 in the socket 1, and the outer conductor 11 abuts against the limiting step 321. The socket 1 and the plug 3 adopt a step positioning and convex limiting structure technology to ensure that the points between the socket 1 and the plug 3 are correctly aligned, and to ensure that the signal received by the sensor can be normally transmitted to the inside of the device for amplification and processing through the substrate 12 and the button assembly 31. At the same time, it is used for positioning and anti-rotation between the socket 1 and the plug 3 to ensure the stability of the plug-in engagement between the socket 1 and the plug 3.

[0030] To improve the ease of operation of the external conductor 232, such as Figure 8 As shown, the outer wall of the second outer conductor 32 is provided with a milled edge 322. When the second outer conductor 32 is tightened, the milled edge 322 is provided to facilitate the tightening of the second outer conductor 32 by force.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
