Detailed implementation manners

[0044] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0045] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means that the related objects before and after are in an "or" relationship.

[0046] In the connector technologies of USB Type-A, USB Type-B, USB Type-C, Micro USB, HDMI and DisplayPort interfaces, frequent plugging and unplugging operations are likely to cause damage to the plug or socket.

[0047] The inventor found that the docking of these interfaces usually relies on the guidance of the shielding case to align the plug and the socket. However, during the docking process, there may be bumps or scratches between the shielding case and the socket. Since the inside of the shielding case contains terminals or electronic components, such long-term bumps or scratches may cause the shielding case to be damaged and shaken, which may further damage the terminals or electronic components, thereby causing damage to the plug or the socket.

[0048] In this application, by optimizing the docking method of the plug structure and the socket structure, a guiding member is used to guide the docking of the plug structure and the socket structure. Before the shielding case contacts the socket structure, the shielding case and the socket structure are aligned through the guiding member, thereby reducing the stress when the shielding case contacts the socket structure. This design can effectively avoid damage or shaking of the shielding case, and further reduce the risk of damage to the plug structure or the socket structure.

[0049] The following combines Figures 1 to 8 A plug, a socket structure, and an endoscope provided by an embodiment of this application are described in detail through specific embodiments and their application scenarios.

[0050] The first aspect of this embodiment describes a plug structure in detail.

[0051] Referring to Figure 1 、 Figure 2 As shown, an embodiment of this application provides a plug structure for docking with a socket structure. It can be understood that during use, the plug structure needs to be docked with the socket structure, so the socket structure is provided with jacks 610 adapted to the socket structure. The plug structure includes a housing 100, a shielding case 200, and a guiding member 300. The housing 100 provides an installation basis for the shielding case 200 and the guiding member 300, that is, the shielding case 200 and the guiding member 300 are installed or connected to the housing 100. A part of the shielding case 200 is received in the housing 100, so that the shielding case 200 is connected to the housing 100, and the wires in the housing 100 can pass through the shielding case 200, and the housing 100 and the shielding case 200 provide protection for the wires.

[0052] Among them, contacts are provided in the shielding case 200. After the plug structure is inserted into the socket structure, the contacts in the shielding case 200 will contact the terminals or contacts in the socket structure, thereby realizing the docking of the plug structure and the socket structure. It is worth understanding that the shielding case 200 is made of a metal material, which not only provides protection for the contacts to prevent them from being damaged, but also plays an electromagnetic shielding role, making the signal more stable during transmission.

[0053] Referring to Figure 2 、 Figure 3As shown, in some solutions, the guide member 300 is disposed around the shielding case 200. It can be understood that the guide member 300 being disposed around the shielding case 200 means that the guide member 300 is distributed around the shielding case 200, that is, the guide member 300 is arranged to surround the shielding case 200. In some embodiments, the guide member 300 extends along the circumferential direction of the shielding case 200, thereby forming a closed annular region that surrounds the shielding case 200. In other embodiments, a plurality of guide members 300 are circumferentially spaced apart along the shielding case 200, and these guide members 300 can be arranged at equal intervals or at unequal intervals. It can be understood that the material of the guide member 300 can be selected as plastic to provide better protection and buffering effects.

[0054] Referring to Figure 1 、 Figure 2 As shown, in some solutions, in the axial direction of the shielding case 200 and in the direction towards the insertion end of the shielding case 200, the guide member 300 protrudes from the insertion end of the shielding case 200. Among them, the insertion end of the shielding case 200 refers to the end where the shielding case 200 is first inserted into the socket structure. That is to say, by making the guide member 300 protrude from the insertion end of the shielding case 200 in the insertion direction, during the insertion process of the plug structure and the socket structure, the guide member 300 can first contact the socket structure to guide the docking of the plug structure and the socket structure. In this way, the shielding case 200 and the socket structure can be aligned, and as the plug structure moves into the socket structure, the aligned shielding case 200 contacts the socket structure and completes the docking, realizing the transmission of signals and electrical energy. During this process, most of the stress generated during docking is borne by the guide member 300, thereby effectively reducing the stress when the shielding case 200 contacts the socket structure and reducing the risk of damage to the shielding case 200 during frequent docking. In some solutions, the guide member 300 is flush with the insertion end of the shielding case 200.

[0055] Referring to Figure 2 、 Figure 3As shown, according to an optional embodiment, the guide member 300 is provided with an installation cavity 310, and the shielding case 200 is disposed within the installation cavity 310. At least a part of the shielding case 200 abuts against the inner wall of the installation cavity 310. It can be understood that the shielding case 200 has a first opening that communicates with the installation cavity 310, enabling the shielding case 200 located within the installation cavity 310 to be docked with the socket structure through the first opening. The design of the first opening not only facilitates the installation of the shielding case 200, allowing it to smoothly enter the guide member 300, but also ensures the effective docking of the shielding case 200 with the socket structure, enhancing the convenience and reliability of the entire assembly process. Herein, the shielding case 200 being disposed within the installation cavity 310 means that the shielding case 200 is completely located within the installation cavity 310. This design protects the shielding case 200 through the guide member 300 when the plug structure is docked with the socket structure, preventing the shielding case 200 from being damaged due to excessive stress when contacting the socket structure. It should be noted that since the shielding case 200 is completely located within the installation cavity 310, even if the plug structure collides or impacts with the outside world when the plug structure and the socket structure are not docked, the shielding case 200 can be protected by the guide member 300, reducing the risk of damage.

[0056] It can be understood that at least a part of the shielding case 200 abutting against the inner wall of the installation cavity 310 means that a part of the shielding case 200 abuts against the inner wall of the installation cavity 310 or the outer wall of the shielding case 200 completely fits against the inner wall of the installation cavity 310. This design enables the shielding case 200 and the guide member 300 to form a whole, with the guide member 300 tightly wrapping and protecting the shielding case 200, thereby further enhancing the strength of the shielding case 200, making it more stable and less prone to damage during use.

[0057] Referring to Figure 2 、 Figure 3 As shown, according to an optional embodiment, the plug structure further includes a center tongue 400 and an electronic component assembly, and the shielding case 200 is disposed around the center tongue 400. Among them, the electronic component assembly includes a PBC board. It can be understood that in order to meet various functions and improve performance, an electronic component assembly needs to be provided in the plug structure. For example, in order to support power supply protocols, data transmission protocols, and prevent signal transmission interference, etc., an electronic component assembly needs to be provided in the plug structure. The PBC board serves as the installation basis for at least some of the electronic components, enabling the electronic components to work together synergistically.

[0058] Among them, the central tongue piece 400 is located inside the shielding case 200 and carries the contacts, serving as the installation basis for the contacts, so as to dock the plug structure with the socket structure. The PBC board is connected to the shielding case 200 and electrically connected to the contacts. This design ensures the relative position stability between the PBC board and the shielding case 200, thereby ensuring the connection stability between the contacts and the PBC board, and further improving the reliability of the overall structure.

[0059] It can be understood that setting the central tongue piece 400 in the plug structure can centrally arrange the contacts, thereby optimizing the signal transmission path and reducing interference and loss. Currently, in the prior art, the central tongue piece 400 is usually located in the socket structure. However, in some special industries, such as the medical industry, the disposable sputum aspirator mirror frequently used needs to be discarded after each use. In order to dock the sputum aspirator mirror with the main device, a socket needs to be set on the sputum aspirator mirror, and the main device is equipped with a plug. Due to the relatively high manufacturing difficulty, the manufacturing cost of the central tongue piece 400 is relatively high. If it is directly discarded, the use cost of the sputum aspirator mirror will increase.

[0060] Through the solution of this application, the relatively high-cost central tongue piece 400, electronic component assemblies, etc. are integrated in the plug to form a reusable structure, and only a simple docking socket is set on the sputum aspirator mirror. This design not only reduces the manufacturing and use costs of the sputum aspirator mirror, but also strengthens and protects the shielding case 200 through the guiding member 300, thereby effectively protecting the central tongue piece 400 during use, making it not easily damaged, and extending the service life of the plug assembly with the central tongue piece 400 and electronic component assemblies.

[0061] Refer to Figure 3 、 Figure 6 As shown, according to an optional embodiment, the shielding case 200 is provided with connection ears 210, and the connection ears 210 are connected to the PCB board 500. By providing the connection ears 210, it is convenient to connect the shielding case 200 to the PCB board 500. In some embodiments, the connection ears 210 protrude from the shielding case 200, and a clamping groove for clamping the connection ears 210 is provided on the PCB board 500. After the connection ears 210 are clamped into the clamping groove, the connection between the shielding case 200 and the PCB board 500 can be realized.

[0062] In some solutions, at least a part of the PCB board 500 is located within the installation cavity 310, and both sides in the width direction of the PCB board 500 are in contact and abut against the inner wall of the installation cavity 310. It can be understood that the PCB board 500 is in a plate-like structure. Exemplarily, the PCB board 500 is in a rectangular plate-like structure, and its width direction refers to the width direction of the rectangular plate. During use, the length direction of this plate-like structure is consistent with the docking direction of the plug structure. By making both sides in the width direction of the PCB board 500 closely contact and abut against the inner wall of the installation cavity 310, a tight connection between the PCB board 500 and the guide member 300 is achieved, enabling them to effectively transfer the acting force and thus form an integral body. Such a design increases the contact area 351 between the PCB board 500 and the inner wall of the installation cavity 310, and improves the connection reliability between the PCB board 500 and the installation cavity 310.

[0063] In some solutions, in the width direction of the PCB board 500, at least a part of the connecting ear 210 is flush with the PCB board 500, so that the connecting ear 210 abuts against the inner wall of the installation cavity 310. That is to say, the PCB board 500 and the connecting ear 210 are in contact with the inner wall of the installation cavity 310 simultaneously in the width direction, thereby forming a stable support relationship between the shielding case 200 and the guide member 300, as well as between the PCB board 500 and the guide member 300. Through this design, the shielding case 200, the guide member 300, and the PCB board 500 can effectively disperse and transfer the force, preventing stress from concentrating on the shielding case 200 or the PCB board 500, thereby reducing the damage risk of the plug structure during use and extending its service life.

[0064] Furthermore, the above plug structure is a type-c model connector. For example, the plug structure can be in the interface form similar to USB Type-C 3.1 Gen 1, USB Type-C 3.1 Gen 2, USB4, Thunderbolt 3, or Thunderbolt 4.

[0065] Refer to Figure 2 、 Figure 3As shown, according to an optional embodiment, in the direction of the width of the vertical shielding case 200, the distance between the shielding case 200 and the inner wall of the installation cavity 310 is less than the distance between the PCB board 500 and the inner wall of the installation cavity 310. It can be understood that in order to make the socket structure more compact, the width direction of the shielding case 200 is set to be the same as the width direction of the PCB board 500, so that there will be a larger contact area in the width direction of the shielding case 200, making it easier for the guiding member 300 to be subjected to a force in the direction perpendicular to the width direction of the shielding case 200. To prevent the force in this direction from pressing on the PCB board 500, a certain distance is provided between the PCB board 500 and the inner wall of the installation cavity 310 in the direction perpendicular to the width direction of the shielding case 200. In this way, even if the guiding member 300 deforms due to the force in the vertical direction, it will not directly contact the PCB board 500, thus reducing the risk of damage to the PCB board 500 and helping to improve the stability of the plug structure.

[0066] Similarly, to protect the shielding case 200, a certain distance is also reserved between the inner wall of the installation cavity 310 and the shielding case 200 in the direction perpendicular to the width direction of the shielding case 200. To provide a buffering effect when the plug structure is stressed, the shielding case 200 is set closer to the inner wall of the installation cavity 310 in the vertical direction. In this way, when the guiding member 300 deforms due to the force, the inner wall of the installation cavity 310 will first bear and absorb part of the force, and then contact the metal shielding case 200 and transfer part of the force to the shielding case 200, effectively dispersing the force. This design helps to protect the shielding case 200 and the PCB board 500 and avoid the situation where the PCB board 500 is directly damaged due to excessive force on the guiding member 300.

[0067] Refer to Figure 3 、 Figure 4 As shown, according to an optional embodiment, a support member 320 is provided in the installation cavity 310. The support member 320 is distributed in the circumferential direction of the shielding case 200 and abuts against the shielding case 200 to provide support. The function of the support member 320 is to keep the shielding case 200 in a stable position in the installation cavity 310, so that the relative position relationship between the shielding case 200 and the guiding member 300 is more stable, which is beneficial to the docking with the socket structure.

[0068] Refer to Figure 4 、 Figure 5As shown, in some schemes, an escape space 330 is provided between the support member 320 and the guide member 300, and the escape space 330 is located on the side of the support member 320 away from the shielding shell 200 body. During the docking process between the socket structure and the plug structure, due to the limitation of manufacturing precision, even if guided by the guide member 300, it is still difficult to completely avoid a certain force between the shielding shell 200 and the socket structure. By providing the escape space 330 between the support member 320 and the guide member 300, when the shielding shell 200 is subjected to force, the force can be effectively transmitted to the support member 320. The support member 320 absorbs the force during the deformation process, and fine-tunes the orientation of the shielding shell 200 through deformation, thereby ensuring that the socket structure and the plug structure can be docked smoothly. This design not only helps to reduce the risk of excessive force on the shielding shell 200, but also improves the reliability and smoothness of the docking process.

[0069] Reference Figure 2 , Figure 3 As shown, according to an optional embodiment, at least part of the guide member 300 is located in the housing 100, the guide member 300 is provided with a limiting groove 370, and the housing 100 is provided with a limiting protrusion 110 that cooperates with the limiting groove 370. Through the cooperation between the limiting groove 370 and the limiting protrusion 110, the guide member 300 can be firmly connected to the housing 100, and the guide member 300 is prevented from being separated from the housing 100 during use.

[0070] Exemplarily, the housing 100 can be molded on the guide member 300 by overmolding. For example, during the overmolding process, the limiting groove 370 on the guide member 300 is partially embedded in the limiting groove 370 and hardened to form a limiting protrusion 110, so that the guide member 300 is firmly connected to the housing 100. In some embodiments, part of the guide member 300 is located in the housing 600, while in other embodiments, the guide member 300 can be completely located in the housing 600. It is understood that the positional relationship between the guide member 300 and the housing 600 can be adjusted according to actual needs, and this embodiment is not limited thereto.

[0071] Reference Figure 2 , Figure 3 As shown, according to an optional embodiment, the guide member 300 is provided with a docking port 340, and the shielding shell 200 can be movably arranged on the guide member 300. When the shielding shell 200 moves relative to the guide member 300, the shielding shell 200 can enter the docking port 340, so that the shielding shell 200 is limitedly matched with the docking port 340 in its circumferential direction, and the guide member 300 is provided with a guide structure 350 (refer to Figure 4 , Figure 5As shown, it guides the shielding case 200 into the docking interface 340. It can be understood that during assembly, the shielding case 200 needs to be installed into the guiding member 300. To facilitate this process, a certain gap needs to be left between the shielding case 200 and the installation cavity 310 to reduce the frictional force between the shielding case 200 and the guiding member 300. Exemplarily, in the direction perpendicular to the width direction of the shielding case 200, there is a certain distance between the shielding case 200 and the inner wall of the installation cavity 310.

[0072] To provide higher stability after the shielding case 200 and the guiding member 300 are assembled, a docking interface 340 is provided on the guiding member 300. During the installation process of the shielding case 200, especially in the final stage of installation, when the shielding case 200 is about to be in place, the guiding structure 350 will guide the shielding case 200 into the docking interface 340. Since the docking interface 340 is in limit cooperation with the shielding case 200 in the circumferential direction of the shielding case 200, it can effectively position and limit the shielding case 200, thereby ensuring the smooth installation process of the shielding case 200 and making it have higher stability after installation. The shielding case 200 is in limit cooperation with the docking interface 340 in its circumferential direction, which means that the size of the docking interface 340 is comparable to the size of the shielding case 200. When the shielding case 200 enters the docking interface 340, the outer wall of the shielding case 200 will be completely attached to the inner wall of the docking interface 340, thereby providing effective support for the shielding case 200. Such a design ensures that the shielding case 200 can be stably positioned after installation, reducing the possibility of shaking and displacement, and further improving the stability and durability of the overall structure.

[0073] Refer to Figure 4 、 Figure 5 As shown, according to an optional embodiment, there are multiple guiding structures 350, and the multiple guiding structures 350 are spaced apart and distributed in the circumferential direction of the shielding case 200. That is to say, some areas of the shielding case 200 are in contact with the guiding structures 350, while other areas are not in contact with the guiding structures 350. The purpose of such a design is to reduce the frictional force between the shielding case 200 and the guiding structures 350 by reducing the contact area, so that the shielding case 200 is easier to install and avoid the problem that the shielding case 200 is difficult to install due to excessive frictional force. By reducing the frictional force, the convenience of installing the shielding case 200 and the smoothness of the overall assembly can be improved.

[0074] Refer to Figure 4 、 Figure 5As shown, according to an optional embodiment, the guiding structure 350 is provided with a fitting surface 351. When the shielding case 200 is located within the docking port 340, the fitting surface 351 is in contact with the outer wall of the shielding case 200. With this design, after the shielding case 200 enters the docking port 340, the fitting surface 351 can form a surface contact with the shielding case 200, thereby providing a more stable limiting effect in the circumferential direction of the shielding case 200 and reducing the shaking during use. Exemplarily, the guiding structure 350 can be a protruding structure provided within the installation cavity 310. The protruding structure is provided with an inclined surface, which guides the shielding case 200 into the docking port 340 and makes the shielding case 200 in contact with the fitting surface 351.

[0075] Referring to Figure 4 、 Figure 5 As shown, according to an optional embodiment, the guiding member 300 is provided with a limiting structure 360. When the shielding case 200 is located within the docking port 340, the limiting structure 360 is in limiting cooperation with the shielding case 200 in the direction in which the shielding case 200 enters the docking port 340. Exemplarily, the limiting structure 360 is a protruding structure provided within the guiding member 300. The limiting structure 360 limits the insertion depth of the shielding case 200 into the docking port 340, thereby fixing the relative position of the shielding case 200 and the guiding member 300 and preventing the shielding case 200 from protruding beyond the guiding member 300 in the insertion direction.

[0076] The second aspect of this embodiment will elaborate on a socket structure in detail.

[0077] Referring to Figure 8 As shown, a socket structure includes a housing 600 and a docking base 700. The housing 600 is provided with insertion holes 610, and the docking base 700 is disposed within the insertion holes 610. The docking base 700 is used to dock with the shielding case 200 in a plug structure in the above embodiment, and the insertion holes 610 are used to accommodate the insertion of the guiding portion in the plug structure in the above embodiment. It can be understood that the housing 600 is designed with a structure adapted to the plug structure so that the plug structure can be smoothly docked with the socket structure.

[0078] The docking base 700 is provided with a hole adapted to the center tongue 400 for the center tongue 400 to insert, and pins or contacts for docking with the contacts in the plug structure are arranged within the hole, thereby realizing the electrical connection between the plug structure and the socket structure.

[0079] The third aspect of this embodiment will elaborate on an endoscope in detail.

[0080] An endoscope includes a socket structure in the above embodiments. The endoscope referred to in the embodiments of the present application may be a sputum aspirator mirror, a bronchoscope, a pyeloscope, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasal speculum, an oral speculum, a laryngoscope, a vaginoscope, a laparoscope, an arthroscope, etc. The embodiments of the present application do not specifically limit the types of endoscopes. Exemplarily, the above socket structure is provided on a disposable sputum aspirator mirror, so that the plug structure with a relatively complex structure and high cost can be reused, reducing the use cost of the disposable sputum aspirator mirror.

[0081] Referring to Figure 7 、 Figure 8 As shown, according to an optional embodiment, the endoscope 10 includes a plug structure in the above embodiments. It can be understood that in the reusable endoscope 10, the above plug structure can be integrated. Considering that the endoscope 10 is a precision instrument and appropriate protective measures are usually taken during use and storage, integrating the plug structure onto the endoscope 10 can effectively reduce the risk of damage to the plug structure. In addition, by integrating the plug structure onto the endoscope 10 instead of installing it on the cable, the situation where the plug structure is impacted or damaged due to the cable swinging during use can be avoided, thereby further extending the service life of the endoscope 10 and improving its stability.

[0082] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
