Technical Field
[0001] This utility model belongs to the field of sensor technology, specifically a quick connection device for flexible sensor detection. Background Technology
[0002] Currently, when connecting flexible sensors to PCB boards, cables are usually directly soldered to the conductive material of the flexible sensor. This method is inexpensive, but it has poor tensile strength and is prone to desoldering, leading to breakage and product failure.
[0003] According to a search, patent document CN218270806U discloses a flexible connection structure for a flexible sensor, including a flexible conductive element, a connecting mechanism, a connecting terminal, and a cable. The connecting terminal is fixedly connected to the cable. The cable is used to connect to a PCB board. The connecting terminal is rotatably connected to the flexible conductive element through the connecting mechanism. An adhesive layer is provided on the side of the flexible conductive element opposite to the connecting terminal, and the flexible conductive element is used to connect the flexible sensor through the adhesive layer. By adopting the above solution, the problems of poor tensile strength, easy desoldering leading to breakage and product failure caused by welding the cable to the flexible sensor, and the high temperature during the welding process easily damaging the flexible sensor are solved.
[0004] The aforementioned comparative documents also have the following shortcomings:
[0005] The connection stability and contact reliability are insufficient. The flexible conductive parts are mostly conductive cloth, and the contact with the connection mechanism (such as the eyelet buckle) is mostly point contact or line contact. Moreover, the metal coating of the conductive cloth is relatively thin. During long-term use, it is easy to cause fluctuations in contact resistance due to wear and oxidation. In particular, in humid and dusty environments, the problem of poor contact is more prominent, which affects the accuracy of sensor signal transmission. Utility Model Content
[0006] To overcome the above-mentioned defects, this utility model provides a quick connection device for flexible sensor detection, which solves the technical problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick connection device for flexible sensor detection, comprising a flexible conductive sheet, a flexible support base at the bottom of the flexible conductive sheet, a protruding post fixedly connected to the top of the flexible support base, the protruding post penetrating the flexible conductive sheet, a connecting ring at the top of the flexible conductive sheet, a cable connected to one side of the connecting ring, the connecting ring being sleeved on the outside of the protruding post, conductive cloth embedded at both ends of the flexible conductive sheet, reinforcing sheets provided on both sides of the conductive cloth, a connecting hole opened in the flexible conductive sheet, an insulating component provided at the top of the flexible conductive sheet, and a connecting terminal for use with the cable provided on one side of the top of the flexible conductive sheet.
[0008] As a further embodiment of this utility model: a first slot is provided on the outer side of the flexible conductive sheet to cooperate with the reinforcing sheet and the conductive cloth, and the ends of the reinforcing sheet and the conductive cloth are embedded in the first slot and fixed by conductive adhesive.
[0009] As a further embodiment of this utility model: the flexible support base is provided with a second slot for use with the reinforcing sheet and the conductive cloth.
[0010] As a further embodiment of this utility model: the insulating component has a third slot that cooperates with the protrusion, the connecting ring, the reinforcing sheet, and the conductive cloth.
[0011] As a further embodiment of this utility model: the bottom of the insulating component is provided with a through hole for use with the connecting terminal and the cable.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. By combining the first slot with the conductive adhesive, and with the reinforcing sheet having an area larger than the end of the conductive cloth, the connection force-bearing area is greatly increased. Combined with the longitudinal support of the second slot, the problem of easy detachment and breakage of the connection between the conductive cloth and the flexible conductive sheet under tension is effectively solved.
[0014] 2. The third slot achieves precise matching of multiple types of sub-slots, which not only realizes the assembly and positioning of core components such as protrusions, connecting rings, and reinforcing plates, ensuring the flexibility of the connection to rotate around the protrusion to relieve deformation stress, but also forms a closed protective space through the covering of insulating parts to prevent external dust and moisture from contacting conductive parts and causing signal abnormalities.
[0015] 3. Through holes serve to organize and protect the cables, preventing damage caused by arbitrary bending or friction with sharp parts. At the same time, the orderly wiring path reduces interference during signal transmission, improving the reliability and service life of the device. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0022] like Figures 1-4 As shown, this utility model provides a technical solution:
[0023] A quick connection device for flexible sensor detection includes a flexible conductive sheet 1, a flexible support base 3 at the bottom of the flexible conductive sheet 1, a protruding post 4 fixedly connected to the top of the flexible support base 3, the protruding post 4 penetrating the flexible conductive sheet 1, a connecting ring 5 at the top of the flexible conductive sheet 1, a cable 6 connected to one side of the connecting ring 5, the connecting ring 5 being sleeved on the outside of the protruding post 4, conductive cloth 8 embedded at both ends of the flexible conductive sheet 1, reinforcing sheets 7 on both sides of the conductive cloth 8, a connecting hole 12 opened inside the flexible conductive sheet 1, an insulating component 2 at the top of the flexible conductive sheet 1, and a connecting terminal 9 for use with the cable 6 on one side of the top of the flexible conductive sheet 1.
[0024] Specifically, when the flexible sensor deforms during the testing process, the flexible support 3 can adapt to the deformation synchronously, and the connecting ring 5 can rotate flexibly around the protrusion 4 to avoid the cable 6 and conductive cloth 8 being pulled and damaged. Through the silicone material of the flexible support 3, both load-bearing stability and flexible deformation of the sensor are guaranteed. The rotation structure of the protrusion 4 and the connecting ring 5 can eliminate the lateral force generated by insertion, removal and deformation. Combined with the strengthening effect of the reinforcing piece 7 on the conductive cloth 8, the risk of the conductive cloth 8 falling off and the lead wire breaking can be greatly reduced.
[0025] The insulating component 2 achieves precise protection for each component through the third slot 13 and through hole 14, which not only avoids signal short circuits but also ensures the neat wiring of the cable 6. Each component is positioned and assembled through the slot, and the connection can be completed quickly without professional tools. The connection terminal 9 is compatible with the standard interface of the testing equipment, which can realize stable signal transmission between the flexible sensor and the testing system. At the same time, the adhesive-backed support can be flexibly adapted to different testing scenarios, taking into account both ease of operation and testing reliability.
[0026] The flexible conductive sheet 1 has a first slot 10 on its outer side for use with the reinforcing sheet 7 and the conductive cloth 8. The ends of the reinforcing sheet 7 and the conductive cloth 8 are embedded in the first slot 10 and fixed with conductive adhesive. The flexible support base 3 has a second slot 11 for use with the reinforcing sheet 7 and the conductive cloth 8. The insulating component 2 has a third slot 13 for use with the protrusion 4, the connecting ring 5 and the reinforcing sheet 7 and the conductive cloth 8. The bottom of the insulating component 2 has a through hole 14 for use with the connecting terminal 9 and the cable 6.
[0027] Specifically, the first slot 10 on the outer side of the flexible conductive sheet 1 forms a lateral limit on the ends of the reinforcing sheet 7 and the conductive cloth 8, and the conductive adhesive achieves a stable bond between the two and the flexible conductive sheet 1. At the same time, the second slot 11 in the flexible support base 3 corresponds to the position of the first slot 10, and forms a longitudinal support and positioning for the bottom of the conductive cloth 8, so as to prevent the conductive cloth 8 from warping or shifting due to force.
[0028] When the insulating component 2 is closed, the third slot 13 inside it forms a precise fit and limit on the protruding post 4, connecting ring 5 and reinforcing plate 7 through the cylindrical slot, annular slot and plate slot respectively, ensuring that each moving part can rotate flexibly within the reserved gap without misalignment. Meanwhile, the through hole 14 at the bottom of the insulating component 2 provides a regular passage for the cable 6, fixing the path of the cable 6 from the connecting ring 5 to the connecting terminal 9, and preventing it from getting tangled or rubbing against other parts.
[0029] By combining the first slot 10 with the conductive adhesive, and with the reinforcing sheet 7 having a larger area than the end of the conductive cloth 8, the connection force-bearing area is greatly increased. Combined with the longitudinal support of the second slot 11, the problems of easy detachment and easy breakage of the connection between the conductive cloth 8 and the flexible conductive sheet 1 are effectively solved.
[0030] The third slot 13 achieves precise matching of multiple types of sub-slots, which not only realizes the assembly and positioning of core components such as protrusion 4, connecting ring 5, and reinforcing plate 7, ensuring the flexibility of the connecting ring 5 to rotate around protrusion 4 to relieve deformation stress, but also forms a closed protective space through the covering of insulating part 2 to prevent external dust and moisture from contacting conductive parts and causing signal abnormalities.
[0031] The through hole 14 serves to organize and protect the cable 6, preventing damage caused by arbitrary bending or friction with sharp parts. At the same time, the orderly wiring path reduces interference during signal transmission, improving the reliability and service life of the device.
[0032] The working principle of this utility model is as follows:
[0033] First, a bearing base is provided by a flexible support base 3 and fixed with adhesive backing. The protrusion 4 at the top of the support base passes through the connection hole 12 of the flexible conductive sheet 1, providing a rotation shaft for the connecting ring 5. The connecting ring 5 is sleeved on the outside of the protrusion 4 and connected to the cable 6. The other end of the cable 6 is fixed to the connection terminal 9 at the top of the flexible conductive sheet 1. At the same time, the two ends of the flexible conductive sheet 1 are embedded with the conductive cloth 8 through the first slot 10. The reinforcing pieces 7 on both sides of the conductive cloth 8, together with the conductive adhesive, achieve a stable connection, forming a signal transmission path of "sensor-conductive cloth 8-flexible conductive sheet 1-connecting ring 5-cable 6-connecting terminal 9-detection equipment".
[0034] Secondly, during detection, the flexible sensor deforms, and the flexible support base 3 can adapt to the deformation synchronously. The connecting ring 5 rotates flexibly around the protrusion 4 to eliminate the lateral force generated by insertion, removal, and deformation. The first slot 10 forms a lateral limit on the conductive cloth 8 and the reinforcing sheet 7. Together with the second slot 11 of the flexible support base 3, it provides longitudinal support to the bottom of the conductive cloth 8. Combined with the increased force-bearing area of the reinforcing sheet 7, it effectively prevents the conductive cloth 8 from falling off or breaking, ensuring the continuity of signal transmission. The reinforcing sheet 7 is made of polyimide, which can effectively disperse the stress at the connection part of the conductive cloth, avoid the conductive cloth from tearing due to repeated bending or pulling, and significantly improve the mechanical strength of the connection between the conductive cloth and the flexible conductive sheet.
[0035] Finally, when the insulating part 2 is closed, the cylindrical groove, annular groove and plate groove of the third slot 13 form precise limits on the protruding post 4, connecting ring 5 and reinforcing plate 7 respectively, ensuring that the moving parts can rotate flexibly and without misalignment. At the same time, a closed space is formed to isolate dust and moisture. The through hole 14 provides a fixed path for the cable 6, avoiding tangling and friction, reducing signal interference, which protects the cable and improves signal stability.
[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
