[0035] The beneficial effects of this application are as follows:

[0036] 1. By soldering pins within the pin insulator, the reliability of the power transmission path is ensured, meeting basic power connection requirements. An induction coil surrounding the pin insulator generates an induced current when current flows through the soldered pins. This current, combined with a control chip, generates an induction signal, enabling real-time monitoring of the connector's current flow status and providing a foundation for device status awareness. Simultaneously, the sensing module generates an unlocking command based on the induction signal. The device can only start or execute actions after receiving this command. This interconnected control of the device via the connector effectively reduces the risk of accidental startup and improves operational controllability.

[0037] 2. The guide step hole at the tail of the pin insulator's through-hole mates with the forward-facing beveled barb structure of the welding pin, providing precise guidance for automated mechanical assembly. The symmetrical flat position of the plug inner sleeve solves the problem of the raised key obstructing the view, reducing assembly alignment difficulty, and decreasing reliance on manual labor and costs. Furthermore, the stepped surface of the pin insulator fits snugly with the stepped hole of the plug inner sleeve, achieving precise axial and radial positioning; the vertical groove of the plug outer shell mates with the raised key of the inner sleeve, with the joint ends fitting snugly, ensuring consistent key positions and preventing assembly misalignment.

[0038] 3. The first connecting groove and platform of the plug housing limit the induction coil and control chip to prevent displacement. Simultaneously, waterproof fixing adhesive, inner mold coating, and outer mold coating form multiple layers of protection, isolating external interference and protecting the sensing components from damage. Furthermore, the third stepped hole in the plug inner sleeve incorporates the soldered pin ends into the protective area to avoid collision damage. The raised step at the front of the outer shell covers the joint gap between the inner sleeve and the outer shell, reducing dust and moisture intrusion and enhancing sealing and mechanical protection.

[0060] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by this application clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0062] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0063] Please see Figure 1 This disclosure provides a connector including a pin insulator 100 and a sensing unit 200. At least one solder pin 110 is connected to the pin insulator 100 along its own axis, and both ends of the solder pin 110 are exposed to the pin insulator 100, forming a first exposed body 111 at one end and a second exposed body 112 at the other end. The first exposed body 111 is used to connect a first electrical device, and the second exposed body 112 is used to connect a second electrical device. Therefore, the first electrical device and the second electrical device can be electrically connected through the connector of this disclosure.

[0064] It should be noted that the first and second power devices mentioned in this disclosure are not limited to two complete and independent devices, but can also be two different module units within a single device.

[0065] Furthermore, the sensing unit 200 includes an induction coil 210 and a control chip 220. The induction coil 210 is disposed around the needle insulator 100 and electrically connected to the control chip 220. The control chip 220 can generate an induction signal based on the induced current generated by the induction coil 210. Therefore, when the first power device and the second power device are connected through a connector, and current flows through the solder pins 110 inside the needle insulator 100, an induced current can be generated in the induction coil 210.

[0066] It should be noted that a sensing module for acquiring sensing signals is installed in the first power equipment and / or the second power equipment.

[0067] Understandably, the soldering pins 110 within the pin insulator 100 can stably connect the first electrical device and the second electrical device, or different module units of the same device, ensuring a power transmission path between them and meeting basic power connection requirements. Simultaneously, the induction coil 210 located around the pin insulator 100 generates an induced current when current flows through the soldering pins 110. This current, combined with the control chip 220, generates an induction signal, enabling real-time monitoring of the current flow status within the connector and providing a foundation for device status sensing.

[0068] Specifically, the induction coil 210 integrated around the pin insulator 100 precisely generates an induced current when current flows through the soldered pin 110, and works with the built-in control chip 220 to generate a unique induction signal. This process is the foundation of "identity verification" that ordinary connectors cannot replicate, enabling real-time monitoring and unique identification of the connector's current flow status.

[0069] Taking a power equipment scenario as an example, the sensing module can be specifically configured in the first power equipment. The sensing coil can only trigger the induced current when the connector provided in this disclosure is connected to the device and a current flows through it. The control chip 220 then generates a unique sensing signal, which in turn generates a device unlocking command. The first power equipment is only allowed to start or execute core actions after recognizing this specific unlocking command.

[0070] As can be foreseen, ordinary connectors, lacking the corresponding induction coil 210 and control chip 220, even if physical connection is achieved, cannot generate specific induced current and signals during current flow, thus failing to trigger the device unlocking mechanism. This fundamentally ensures that the device only recognizes the connectors provided in this disclosure; other connectors, regardless of physical compatibility, cannot pass the induction signal verification process. Completely blocking the use of unauthorized connectors effectively improves device controllability and reduces the risk of accidental activation.

[0071] Please see Figure 1 In one embodiment, at least one through hole for connecting a soldering pin 110 is provided along the axial direction of the needle insulator 100. Therefore, the soldering pin 110 is detachably connected to the needle insulator 100 through the corresponding through hole.

[0072] Specifically, the through-holes within the pin insulator 100 can be configured according to voltage and the number of solder pins 110, and the size of the through-holes matches the size of the solder pins 110. Therefore, it can adapt to connection scenarios with different voltage levels and different numbers of solder pins 110, broadening the connector's applicability. Specifically, a slightly enlarged stepped hole with a guiding function is provided at the tail of the through-hole, and the solder pins 110 have forward-facing barbs, positioning steps, and soldering cups on their exterior. The pin tip of the solder pin 110 is also designed with a smooth mirror surface. It is understandable that the stepped hole at the end of the through-hole within the pin insulator 100, and the forward-facing barb design of the solder pins 110, facilitate subsequent automated mechanical assembly. Simultaneously, the simplified internal structure of the pin insulator 100 reduces mold design and manufacturing costs, and decreases the cost of replacing vulnerable parts. Furthermore, the positioning steps on the solder pins 110 ensure accurate installation, preventing poor contact due to positional deviations. The welding cup design facilitates stable welding, and the smooth mirror-like contact structure at the front end further ensures the reliability and stability of power transmission.

[0073] Please see Figure 1 and Figure 2 In one embodiment, a plug inner sleeve 300 is provided around the needle insulator 100, and a through hole for connecting the needle insulator 100 is provided in the center of the plug inner sleeve 300. The through hole of the plug inner sleeve 300 is a stepped hole, including a first stepped hole 301 and a second stepped hole 302, and the diameter of the first stepped hole 301 is larger than the diameter of the second stepped hole 302.

[0074] The outer diameter surface of the needle insulator 100 adopts a stepped surface, which includes a first stepped surface 101, a second stepped surface 102, a third stepped surface 103 and a fourth stepped surface 104 in sequence along the first direction DX. The second stepped surface 102 is the maximum diameter of the needle insulator 100, and the diameter of the third stepped surface 103 is larger than the diameter of the fourth stepped surface 104.

[0075] Furthermore, the second stepped surface 102 is fitted to the inner wall of the first stepped hole 301, and a first gap 310 is maintained between the inner wall of the second stepped hole 302 and the third stepped surface 103 and the fourth stepped surface 104. By fitting the second stepped surface 102 to the inner wall of the first stepped hole 301, one end face of the second stepped surface 102 is fitted to the end face of the second stepped hole 302, achieving precise positioning between the pin insulator 100 and the plug inner sleeve 300. The precise fit between the stepped surface of the pin insulator 100 and the stepped hole of the plug inner sleeve 300 ensures the axial and radial positioning accuracy between the pin insulator 100 and the plug inner sleeve 300, reduces assembly deviations, and improves the stability of the overall structure. The first gap 310 left between the inner wall of the second step hole 302 and the third step surface 103 and the fourth step surface 104 of the needle insulator 100 provides a certain margin of error for the assembly process, avoids assembly jamming or structural stress caused by minor dimensional errors, and ensures the smoothness of the assembly process.

[0076] Furthermore, the stepped hole in the plug inner sleeve 300 also includes a third stepped hole 303. The third stepped hole 303 is located at the end of the plug inner sleeve 300, and its diameter is smaller than that of the second stepped hole 302. A chamfer 3031 is provided near the end of the plug inner sleeve 300 in the third stepped hole 303. By providing the third stepped hole 303, the end of the soldering pin 110 is located within the protective area of ​​the third stepped hole 303. The chamfer 3031 on the third stepped hole 303 serves as a guiding structure to facilitate connection between the connector and the electrical equipment. By acting as a guide when the connector is mated with the electrical equipment, it reduces the difficulty of alignment and improves the convenience and efficiency of the connection operation.

[0077] Understandably, the third step hole 303 at the end of the plug inner sleeve 300 incorporates the pin of the soldering pin 110 into the protective area, effectively preventing damage to the soldering pin 110 caused by external impact during assembly, transportation or use, and improving the durability and safety of the connector.

[0078] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 In one embodiment, a plug housing 400 is also provided on the outside of the plug inner sleeve 300, and the plug housing 400 is snapped together with the plug inner sleeve 300.

[0079] Specifically, the inner surface of the plug housing 400 has an axially oriented vertical groove 401, and the outer surface of the plug inner sleeve 300 has a forward-facing raised key 330 that mates with the vertical groove 401. The axial vertical groove 401 on the inner surface of the plug housing 400 mates with the raised key 330 on the surface of the plug inner sleeve 300, and the outermost end of the plug inner sleeve 300 mates with the rear inner wall of the plug housing 400. This structure effectively unifies and limits the markings on the plug inner sleeve 300 and the plug housing 400.

[0080] Understandably, the vertical groove 401 of the plug housing 400 and the raised key 330 of the plug inner sleeve 300 cooperate with each other. Combined with the fit between the outer side of the largest end of the plug inner sleeve 300 and the inner rear wall of the plug housing 400, the mechanical snap-fit ​​structure achieves precise positioning and firm connection between the two, effectively ensuring the uniformity of the key positions, avoiding misalignment or loosening during assembly, and improving the stability of the overall structure.

[0081] Furthermore, the largest stepped ring of the protrusion in the middle of the plug inner sleeve 300 has axially symmetrical flat portions at positions near the raised key 330 and on the opposite side. These symmetrical flat portions facilitate the assembly of the plug inner sleeve 300 and the plug housing 400, allowing for easier determination of the key's direction and position. During assembly, since the central step of the plug inner sleeve 300 completely obstructs the view of the raised key 330, designing flat portions at that position significantly reduces alignment difficulties during assembly, thereby indirectly reducing labor costs.

[0082] Specifically, a snap-fit ​​hole 410 is provided on the plug housing 400, and a snap-fit ​​block 420 corresponding to the snap-fit ​​hole 410 is provided on the outer surface of the plug inner sleeve 300. The snap-fit ​​block 420 includes a first guide surface 421 and a first snap-fit ​​surface 422, with the first guide surface 421 extending from the first snap-fit ​​surface 422 to the outer surface of the plug inner sleeve 300. Elongated slots 430 penetrating the body of the plug inner sleeve 300 are respectively provided on both sides of the snap-fit ​​block 420 of the plug inner sleeve 300.

[0083] Furthermore, the first guiding surface 421 of the latching block 420 extends from the first latching surface 422 to the outer surface of the plug inner sleeve 300, forming a natural guiding structure. When the plug outer shell 400 mates with the inner sleeve, it guides the latching block 420 to slide smoothly into the latching hole 410, reducing alignment resistance and making the latching process smoother and more efficient. Simultaneously, the latching block 420 adopts a U-shaped cable-like bevel structure and optimizes the internal cavity by reducing adhesive residue. Combined with the long, parallel slots running through both sides, this significantly enhances the elastic deformation capability of the latching block 420. This increased elasticity makes the locking of the plug and socket more secure and reliable, while also making unlocking easier and effectively optimizing the locking and unlocking experience.

[0084] The flexible structure design ensures a secure lock between the locking block 420 and the locking hole 410, preventing loosening during use. It also reduces the operating force through reasonable deformation space, making the locking and unlocking process easy and controllable, thus balancing connection reliability and ease of use.

[0085] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In one embodiment, a first connecting portion 440 is provided on the plug housing 400, which is disposed within the length region of the soldering pin 110. The first connecting portion 440 has a first connecting groove 441 and a first connecting platform 442. The first connecting platform 442 includes three-sided enclosures 443, and the opening formed by the three-sided enclosures 443 connects to the first connecting groove 441. The induction coil 210 is wound within the first connecting groove 441, and the control chip 220 is connected within the first connecting platform 442. This effectively protects the induction coil 210 and the control chip 220 from displacement, and also prevents damage to the induction coil 210 assembly from subsequent injection molding processes.

[0086] Furthermore, a layer of waterproof fixing adhesive is poured around the induction coil 210 assembly, and the outer surface of the waterproof adhesive needs to be treated with inner mold coating 600 for waterproofing and fixing position.

[0087] For example, in one embodiment, the connector provided in this disclosure further includes an inner mold covering 600 and an outer mold covering 700. The inner mold covering 600 is sleeved on the first connecting portion 440 of the plug housing 400, such that the induction coil 210 and the control chip 220 are both located within the coverage area of ​​the inner mold covering 600, and the outer mold covering 700 is sleeved on the outside of the inner mold covering 600.

[0088] An outer mold coating 700 is added to the outer layer of the inner mold coating 600. Simultaneously, arrow markings are made on the surface of the outer mold, with the arrow direction consistent with the keyway direction. The outer mold coating 700 primarily protects the induction coil 210 assembly from damage and interference.

[0089] Furthermore, an inwardly protruding step is provided at the front end of the plug housing 400, the inner diameter of which is similar to the inner diameter of the plug inner sleeve 300. This structure effectively conceals the joint gap between the plug inner sleeve 300 and the housing, providing effective protection. This reduces the intrusion of foreign objects such as dust and moisture, while enhancing the overall sealing and mechanical protection capabilities of the structure.

[0090] Understandably, the first connecting groove 441 and the first connecting platform 442 of the plug housing 400 provide adaptive accommodation and positioning for the induction coil 210 and the control chip 220, respectively, effectively preventing positional shifts during assembly or use. Simultaneously, this structure blocks direct impact from subsequent injection molding processes on the induction coil 210 assembly, preventing damage to core components. The waterproof adhesive around the induction coil 210 provides basic sealing and fixation, while the inner mold encapsulation 600 fully covers the induction coil 210 and the control chip 220, further enhancing waterproofing and positional fixation. The outer mold encapsulation 700 is fitted outside the inner mold encapsulation 600, providing double protection to effectively isolate external environmental interference, protecting the induction coil 210 assembly from damage and improving the overall structural stability.

[0091] Please see Figure 1 , Figure 2 , Figure 9 and Figure 10 In one embodiment, a cable clamping structure 500 is also connected to one side of the plug inner sleeve 300. The cable clamping structure 500 can be used to connect the cable of the power equipment, and the cable is connected to the solder pin 110 on the pin insulator 100.

[0092] Furthermore, the cable clamping structure 500 includes a cable clamp body 510 and a tail nut 520. The cable clamp body 510 includes a connecting end 511 and a clamping end 512. The connecting end 511 is sleeved on the first stepped surface 101, and a positioning block 5110 is provided on the connecting end 511. A first positioning groove 5111 for engaging the positioning block 5110 is provided on the second stepped surface 102.

[0093] Specifically, the first positioning groove 5111 is formed at the outer maximum diameter step of the pin insulator 100 and is strip-shaped. The positioning block 5110 is provided on the periphery of the connecting end 511 and is a raised strip. The small end of the tail of the pin insulator 100 mates with the inner wall of the connecting end 511, and the positioning block 5110 mates with the first positioning groove 5111. By mates the positioning block 5110 and the first positioning groove 5111, the arrangement of the pin insulator 100 assembly is effectively unified with the key positions of the plug inner sleeve 300 and the plug outer shell 400.

[0094] The clamping end 512 includes a plurality of clamping blocks 5120 that can be offset toward the axis of the cable clamp body 510. A tail nut 520 is sleeved on the cable clamp body 510, and a drive guide surface 521 is provided inside the tail nut 520 for driving the clamping blocks 5120 to offset toward the axis of the cable clamp body 510. The clamping blocks 5120 also have protrusions 5121 for clamping cables, and anti-slip textures are provided on the clamping surface of the protrusions 5121.

[0095] It can be understood that the tail nut 520 is sleeved on the cable clamp body 510 and connected to the inner sleeve 300 of the plug. The tail nut 520 is used to drive the clamping block 5120 to deflect towards the axis direction of the cable clamp body 510.

[0096] Specifically, an external thread for connecting the tail nut 520 is provided on the inner sleeve 300 of the plug. A second positioning groove 320 is provided at the external thread. The second positioning groove 320 corresponds to the first positioning groove 5111, and the positioning block 5110 can be simultaneously clamped in the first positioning groove 5111 and the second positioning groove 320. It can be understood that through this structure, the connecting part can be firmly protected therein. At the same time, the connecting part is designed with a structure that is large at the front and small at the back. The inner part of the small end at the back is set as a toothed structure and is cut into a four-equal-part petal structure. When the tail nut 520 tightens the screw teeth, the petal structure shrinks evenly, which can play a role in firmly protecting the cable.

[0097] The positioning block 5110 of the connecting end 511 of the cable clamp body 510 is precisely matched with the first positioning groove 5111 of the pin insulator 100 and the second positioning groove 320 of the inner sleeve 300 of the plug, ensuring that the component arrangement directions of the pin insulator 100, the inner sleeve 300 of the plug and the cable clamp are consistent, and effectively unified with the key positions of the inner sleeve 300 of the plug and the plug housing 400, avoiding assembly misalignment and improving the consistency and reliability of the overall structure.

[0098] The tail nut 520 is connected to the external thread of the inner sleeve 300 of the plug, fastening and integrating components such as the cable clamp and the pin insulator 100 to form a compact overall structure, effectively improving the anti-vibration and anti-impact capabilities of the connector during use and reducing the relative displacement between components.

[0099] In summary, the present disclosure provides a connector. Through the welding pin 110 in the pin insulator 100, the reliability of the power transmission path can be ensured to meet the basic power connection requirements. The induction coil 210 outside the pin insulator 100 can generate an induced current when the welding pin 110 conducts current, and cooperate with the control chip 220 to generate an induction signal to realize real-time monitoring of the current-carrying state of the connector, providing a basis for device state perception. At the same time, the induction module generates an unlocking instruction based on the induction signal. The device needs to obtain the instruction before it can start or execute an action, realizing the linkage control of the device through the connector, effectively reducing the risk of mis-start and improving the operation controllability.

[0100] The guide step hole at the tail of the through hole of the pin insulator 100 mates with the forward-facing beveled barb structure of the welding pin 110, providing precise guidance for automated mechanical assembly. The symmetrical flat position of the plug inner sleeve 300 solves the problem of obstruction of the view of the raised key 330, reducing the difficulty of assembly alignment and decreasing reliance on manual labor and costs. Furthermore, the stepped surface of the pin insulator 100 fits snugly with the stepped hole of the plug inner sleeve 300, achieving precise axial and radial positioning. The vertical groove 401 of the plug outer shell 400 mates with the raised key 330 of the inner sleeve, with the joint ends fitting snugly to ensure consistent key positions and avoid assembly misalignment.

[0101] The plug housing 400's first connecting groove 441 and platform limit the induction coil 210 and control chip 220 to prevent displacement. The inner mold coating 600 and outer mold coating 700 form multiple layers of protection, isolating external interference and protecting the sensing components from damage. The plug inner sleeve 300's third step hole 303 incorporates the end of the soldered pin 110 into the protected area, preventing collision damage. The raised step at the front of the housing covers the joint gap between the inner sleeve and the housing, reducing dust and moisture intrusion and enhancing sealing and mechanical protection.
