DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0045] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, not to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

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

[0047] The inventors 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, the shielding case can collide or scratch with the socket. Since the shielding case contains terminals or electronic components inside, such long-term collision or scratching can cause the shielding case to be damaged and shaken, and then cause the terminals or electronic components to be damaged, thereby causing damage to the plug or the socket.

[0048] The plug structure and the socket structure are connected by optimizing the connection mode of the plug structure and the socket structure, and the guide member is used to guide the connection of the plug structure and the socket structure. Before the shielding shell contacts the socket structure, the guide member is used to align the shielding shell and the socket structure, thereby reducing the stress when the shielding shell contacts the socket structure. This design can effectively prevent damage or shaking of the shielding shell, thereby reducing the risk of damage to the plug structure or the socket structure.

[0049] The plug, socket structure and endoscope provided by the embodiment of the present application will be described in detail below in combination with specific embodiments and application scenarios.

[0050] The first aspect of the embodiment provides a detailed description of a plug structure.

[0051] Referring to FIGS. 1 and 2, the embodiment of the present application provides a plug structure for connecting with a socket structure. It can be understood that the plug structure needs to be connected with the socket structure in use, and therefore the socket structure is provided with a socket 610 adapted to the socket structure. The plug structure includes a housing 100, a shielding shell 200 and a guide member 300. The housing 100 provides a mounting basis for the shielding shell 200 and the guide member 300, that is, the shielding shell 200 and the guide member 300 are mounted or connected to the housing 100. Part of the shielding shell 200 is accommodated in the housing 100, so that the shielding shell 200 and the housing 100 are connected together, and the lines in the housing 100 can pass through the shielding shell 200, thereby protecting the lines by the housing 100 and the shielding shell 200.

[0052] The shielding shell 200 is provided with contacts. When the plug structure is inserted into the socket structure, the contacts in the shielding shell 200 will contact the terminals or contacts in the socket structure, thereby realizing the connection of the plug structure and the socket structure. It can be understood that the shielding shell 200 is made of metal material, which not only protects the contacts from being damaged, but also has the effect of electromagnetic shielding, so that the signal transmission is more stable.

[0053] Referring to FIGS. 2 and 3, in some schemes, the guide member 300 is arranged around the shielding shell 200. It can be understood that the guide member 300 is arranged around the shielding shell 200, which means that the guide member 300 is distributed around the shielding shell 200, that is, the guide member 300 is arranged around the shielding shell 200. In some embodiments, the guide member 300 is arranged along the circumference of the shielding shell 200, thereby forming a closed annular region surrounding the shielding shell 200. In other embodiments, a plurality of guide members 300 are distributed along the circumference of the shielding shell 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 plastic to provide better protection and buffering effect.

[0054] Referring to FIG. 1 and FIG. 2, in some embodiments, the guide 300 protrudes from the plug end of the shielding shell 200 in the axial direction of the shielding shell 200 and towards the plug end of the shielding shell 200. Here, the plug end of the shielding shell 200 refers to the end of the shielding shell 200 that is first inserted into the socket structure. That is, by making the guide 300 protrude from the plug end of the shielding shell 200 in the plug direction, the guide 300 can be brought into contact with the socket structure first during the plugging of the plug structure and the socket structure, so as to guide the plugging of the plug structure and the socket structure. In this way, the shielding shell 200 and the socket structure are aligned, and as the plug structure moves towards the inside of the socket structure, the aligned shielding shell 200 and the socket structure are brought into contact and completed plugging, so as to realize the transmission of signals and electric energy. During this process, most of the stress generated during plugging is borne by the guide 300, thereby effectively reducing the stress of the shielding shell 200 when it comes into contact with the socket structure, and reducing the risk of damage to the shielding shell 200 during frequent plugging. In some embodiments, the guide 300 is flush with the plug end of the shielding shell 200.

[0055] Referring to FIG. 2 and FIG. 3, according to an optional embodiment, the guide 300 is provided with a mounting cavity 310, and the shielding shell 200 is arranged in the mounting cavity 310, and at least part of the shielding shell 200 abuts against the inner wall of the mounting cavity 310. It can be understood that the shielding shell 200 has a first opening that is in communication with the mounting cavity 310, so that the shielding shell 200 located in the mounting cavity 310 can be plugged into the socket structure through the first opening. The design of the first opening not only facilitates the installation of the shielding shell 200, but also ensures the effective plugging of the shielding shell 200 and the socket structure, thereby improving the convenience and reliability of the entire assembly process. Here, the shielding shell 200 arranged in the mounting cavity 310 means that the shielding shell 200 is completely located in the mounting cavity 310. This design protects the shielding shell 200 through the guide 300 when the plug structure is plugged into the socket structure, so as to prevent the shielding shell 200 from being damaged due to excessive stress when it comes into contact with the socket structure. It should be noted that since the shielding shell 200 is completely located in the mounting cavity 310, even if the plug structure collides or collides with the outside world when the plug structure and the socket structure are not plugged, the shielding shell 200 can be protected by the guide 300 to reduce the risk of damage.

[0056] It can be understood that the abutment of at least part of the shielding shell 200 against the inner wall of the mounting cavity 310 means that part of the shielding shell 200 abuts against the inner wall of the mounting cavity 310 or the outer wall of the shielding shell 200 completely fits the inner wall of the mounting cavity 310. This design can make the shielding shell 200 and the guide 300 form an integral whole, and the shielding shell 200 can be tightly wrapped and protected by the guide 300, thereby further improving the strength of the shielding shell 200 and making it more stable and less likely to be damaged during use.

[0057] Referring to FIG. 2 and FIG. 3, according to an optional embodiment, the plug structure further comprises a center tongue 400 and an electronic component assembly, and the shielding shell 200 is arranged around the center tongue 400. The electronic component assembly comprises a PBC board. It can be understood that in order to meet various functions and improve performance, it is necessary to arrange the electronic component assembly in the plug structure. For example, in order to support power supply protocols, data transmission protocols and prevent signal transmission from being disturbed, it is necessary to arrange the electronic component assembly in the plug structure. The PBC board serves as a mounting base for at least part of the electronic components to enable the electronic components to work cooperatively.

[0058] The center tongue 400 is located in the shielding shell 200 and carries the contacts as a mounting base for the contacts to enable the plug structure to be connected with the socket structure. The PBC board is connected with the shielding shell 200 and is electrically connected with the contacts. This design ensures the relative position between the PBC board and the shielding shell 200 to be stable, thereby ensuring the connection between the contacts and the PBC board to be stable and further improving the reliability of the overall structure.

[0059] It can be understood that arranging the center tongue 400 in the plug structure can concentrate the arrangement of the contacts, thereby optimizing the signal transmission path and reducing interference and loss. At present, in the prior art, the center tongue 400 is usually arranged in the socket structure. However, in some special industries, such as the medical industry, a disposable sputum suction mirror is frequently used and needs to be discarded after each use. In order to enable the sputum suction mirror to be connected with a main device, the socket needs to be arranged on the sputum suction mirror, and the main device is provided with a plug. Since the manufacturing difficulty is relatively high, the manufacturing cost of the center tongue 400 is relatively high, and if it is directly discarded, the use cost of the sputum suction mirror will be increased.

[0060] According to the scheme of the present application, the center tongue 400 and the electronic component assembly with relatively high cost are integrated in the plug to form a reusable structure, and only a simple docking port is arranged on the sputum suction mirror. This design not only reduces the manufacturing and use cost of the sputum suction mirror, but also strengthens and protects the shielding shell 200 through the guide 300, thereby effectively protecting the center tongue 400 in use, making it not easy to be damaged, and prolonging the service life of the plug assembly with the center tongue 400 and the electronic component assembly.

[0061] Referring to FIG. 3 and FIG. 6, according to an optional embodiment, the shielding shell 200 is provided with a connecting lug 210, and the connecting lug 210 is connected with the PCB board 500. The connecting lug 210 can facilitate the connection between the shielding shell 200 and the PCB board 500. In some embodiments, the connecting lug 210 protrudes from the shielding shell 200, and a clamping groove is arranged on the PCB board 500 to clamp the connecting lug 210. When the connecting lug 210 is clamped in the clamping groove, the connection between the shielding shell 200 and the PCB board 500 is achieved.

[0062] In some embodiments, at least part of the PCB 500 is located in the mounting cavity 310, and the two sides of the PCB 500 in the width direction are in close contact with and abut against the inner wall of the mounting cavity 310. It can be understood that the PCB 500 is a plate-shaped structure, and the width direction of the PCB 500 is the width direction of the rectangular plate. In use, the length direction of the plate-shaped structure is consistent with the direction of the plug structure. By making the two sides of the PCB 500 in the width direction closely contact and abut against the inner wall of the mounting cavity 310, the close connection between the PCB 500 and the guide 300 is achieved, so that they can effectively transmit the force and form an integral whole. This design increases the contact area 351 between the PCB 500 and the inner wall of the mounting cavity 310, and improves the connection reliability between the PCB 500 and the mounting cavity 310.

[0063] In some embodiments, at least part of the connecting lug 210 is flush with the PCB 500 in the width direction of the PCB 500, so that the connecting lug 210 abuts against the inner wall of the mounting cavity 310. That is, the PCB 500 and the connecting lug 210 simultaneously contact the inner wall of the mounting cavity 310 in the width direction, thereby forming a stable support relationship between the shielding shell 200 and the guide 300, and between the PCB 500 and the guide 300. Through this design, the shielding shell 200, the guide 300 and the PCB 500 can effectively disperse and transmit the force, preventing stress concentration on the shielding shell 200 or the PCB 500, thereby reducing the risk of damage to the plug structure during use and prolonging its service life.

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

[0065] Referring to FIG. 2 and FIG. 3, according to an optional embodiment, the distance between the shielding shell 200 and the inner wall of the mounting cavity 310 is less than the distance between the PCB 500 and the inner wall of the mounting cavity 310 in the direction perpendicular to the width direction of the shielding shell 200. It can be understood that, in order to make the plug structure more compact, the width direction of the shielding shell 200 is arranged to be consistent with the width direction of the PCB 500, so that there is a larger contact area in the width direction of the shielding shell 200, so that the guide 300 is more susceptible to force in the direction perpendicular to the width direction of the shielding shell 200. In order to prevent the force in this direction from pressing the PCB 500, a certain distance is arranged between the PCB 500 and the inner wall of the mounting cavity 310 in the direction perpendicular to the width direction of the shielding shell 200. In this way, even if the guide 300 deforms in the vertical direction due to force, it will not directly contact the PCB 500, thereby reducing the risk of damage to the PCB 500 and helping to improve the stability of the plug structure.

[0066] Similarly, in order to protect the shielding shell 200, a certain distance is also reserved between the inner wall of the mounting cavity 310 and the shielding shell 200 in the direction perpendicular to the width direction of the shielding shell 200. In order to provide a buffering effect when the plug structure is subjected to force, the shielding shell 200 is arranged closer to the inner wall of the mounting cavity 310 in the vertical direction. In this way, when the guide 300 deforms due to force, the inner wall of the mounting cavity 310 will first bear and absorb part of the force, and then contact the metal shielding shell 200 and transmit part of the force to the shielding shell 200, thereby effectively dispersing the force. This design helps to protect the shielding shell 200 and the PCB 500, and avoids the situation where the PCB 500 is directly damaged due to excessive force on the guide 300.

[0067] Referring to FIG. 3 and FIG. 4, according to an optional embodiment, a support 320 is arranged in the mounting cavity 310, and the support 320 is distributed in the circumferential direction of the shielding shell 200 and abuts against the shielding shell 200 to provide support. The function of the support 320 is to maintain the stable position of the shielding shell 200 in the mounting cavity 310, so that the relative positional relationship between the shielding shell 200 and the guide 300 is more stable, which is conducive to the docking with the socket structure.

[0068] Referring to FIG. 4 and FIG. 5, in some embodiments, a clearance space 330 is provided between the support 320 and the guide 300, and the clearance space 330 is located on the side of the support 320 away from the body of the shielding shell 200. During the docking process of the socket structure and the plug structure, due to the limitation of manufacturing precision, it is still difficult to completely avoid the generation of a certain force between the shielding shell 200 and the socket structure even if the guide 300 is used for guiding. By providing the clearance space 330 between the support 320 and the guide 300, when the shielding shell 200 is subjected to a force, the force can be effectively transmitted to the support 320. The support 320 absorbs the force during deformation and adjusts the orientation of the shielding shell 200 through deformation, thereby ensuring that the socket structure and the plug structure can be smoothly docked. This design not only helps to reduce the risk of the shielding shell 200 being subjected to excessive force, but also improves the reliability and smoothness of the docking process.

[0069] Referring to FIG. 2 and FIG. 3, according to an optional embodiment, at least part of the guide 300 is located in the housing 100, and the guide 300 is provided with a limiting groove 370, and the housing 100 is provided with a limiting protrusion 110 matched with the limiting groove 370. Through the cooperation of the limiting groove 370 and the limiting protrusion 110, the guide 300 and the housing 100 can be firmly connected, and the separation of the guide 300 and the housing 100 during use can be avoided.

[0070] For example, the housing 100 can be formed on the guide 300 by means of overmolding. For example, during the overmolding process, the material of the housing 100 is partially embedded in the limiting groove 370 and hardened to form the limiting protrusion 110, thereby firmly connecting the guide 300 and the housing 100. In some embodiments, part of the guide 300 is located in the shell 600, and in other embodiments, the guide 300 can be completely located in the shell 600. It can be understood that the positional relationship between the guide 300 and the shell 600 can be adjusted according to actual needs, and this embodiment does not limit this.

[0071] Referring to FIG. 2 and FIG. 3, according to an optional embodiment, the guide 300 is provided with a docking interface 340, and the shielding shell 200 is movably arranged on the guide 300. When the shielding shell 200 moves relative to the guide 300, the shielding shell 200 can enter the docking interface 340, so that the shielding shell 200 is limited and matched with the docking interface 340 in the circumferential direction of the shielding shell 200. The guide 300 is provided with a guide structure 350 (referring to FIG. 4 and FIG. 5) to guide the shielding shell 200 to enter the docking interface 340. It can be understood that during assembly, the shielding shell 200 needs to be installed into the guide 300. In order to facilitate this process, a certain distance needs to be left between the shielding shell 200 and the installation cavity 310 to reduce the friction between the shielding shell 200 and the guide 300. Exemplarily, in the direction perpendicular to the width direction of the shielding shell 200, there is a certain distance between the inner wall of the installation cavity 310 and the shielding shell 200.

[0072] In order to provide higher stability after the shielding shell 200 and the guide 300 are assembled, the guide 300 is provided with the docking interface 340. During the installation process of the shielding shell 200, especially in the final stage of installation, when the shielding shell 200 is about to be in place, the guide structure 350 will guide the shielding shell 200 to enter the docking interface 340. Since the docking interface 340 is limited and matched with the shielding shell 200 in the circumferential direction of the shielding shell 200, the shielding shell 200 can be effectively positioned and limited, thereby ensuring the smoothness of the installation process of the shielding shell 200 and providing higher stability after installation. The shielding shell 200 is limited and matched with the docking interface 340 in the circumferential direction of the shielding shell 200, which means that the size of the docking interface 340 is comparable to the size of the shielding shell 200. After the shielding shell 200 enters the docking interface 340, the outer wall of the shielding shell 200 will completely fit the inner wall of the docking interface 340, thereby providing effective support for the shielding shell 200. This design ensures that the shielding shell 200 can be stably positioned after installation, reduces the possibility of shaking and displacement, and further improves the stability and durability of the overall structure.

[0073] Referring to FIG. 4 and FIG. 5, according to an optional embodiment, the guide structure 350 is provided in plurality and is spaced apart in the circumferential direction of the shielding shell 200. That is, part of the area of the shielding shell 200 is in contact with the guide structure 350, while the other part of the area is not in contact with the guide structure 350. The purpose of this design is to reduce the friction between the shielding shell 200 and the guide structure 350 by reducing the contact area, so that the shielding shell 200 is easier to install, and the problem of difficult installation of the shielding shell 200 due to excessive friction is avoided. By reducing the friction, the convenience of installation of the shielding shell 200 and the smoothness of the overall assembly can be improved.

[0074] Referring to FIG. 4 and FIG. 5, according to an optional embodiment, the guide structure 350 is provided with a fitting surface 351, which is fitted with the outer wall of the shielding shell 200 when the shielding shell 200 is located in the mating interface 340. Through this design, after the shielding shell 200 enters the mating interface 340, the fitting surface 351 can form a surface contact with the shielding shell 200, thereby providing a more stable limiting effect in the circumferential direction of the shielding shell 200 and reducing the shaking in use. Exemplarily, the guide structure 350 can be a protruding structure provided in the mounting cavity 310, which is provided with an inclined surface, which guides the shielding shell 200 to enter the mating interface 340 and makes the shielding shell 200 fit with the fitting surface 351.

[0075] Referring to FIG. 4 and FIG. 5, according to an optional embodiment, the guide structure 300 is provided with a limiting structure 360, which is limitedly matched with the shielding shell 200 in the direction in which the shielding shell 200 enters the mating interface 340 when the shielding shell 200 is located in the mating interface 340. Exemplarily, the limiting structure 360 is a protruding structure provided in the guide structure 300, which limits the depth of the shielding shell 200 inserted into the mating interface 340, thereby fixing the relative position of the shielding shell 200 and the guide structure 300 and avoiding the shielding shell 200 protruding from the guide structure 300 in the insertion direction.

[0076] The second aspect of the embodiment is to describe a socket structure in detail.

[0077] Referring to FIG. 8, a socket structure includes a housing 600 and a mating seat 700, the housing 600 is provided with a socket 610, and the mating seat 700 is provided in the socket 610. The mating seat 700 is used to mate with the shielding shell 200 in the plug structure in the above embodiment, and the socket 610 is used to accommodate the guide part in the plug structure in the above embodiment. It can be understood that the housing 600 is designed to be adapted to the plug structure, so that the plug structure can be smoothly mated with the socket structure.
