Description

A connector structure and medical device Technical Field

[0001] This application relates to the technical field of medical devices, and more specifically, to a connector structure and medical device. Background Technology

[0002] Currently, most medical devices connect their main unit and peripherals via connectors, which include plugs and sockets. In existing technologies, the plug and socket are locked or unlocked by threads or snaps. When the plug and socket are locked, they are not easily dislodged under strong external forces, ensuring the reliability of the connection.

[0003] When multiple connectors exist between the main unit and peripherals of a medical device to facilitate the connection of various peripherals, or when the main unit and peripherals need to be frequently connected or disconnected to replace different types of peripherals, the plugs and sockets in the connectors require frequent tightening or unlocking to achieve the desired connection or disconnection. Current technologies using threads or snap-fit ​​mechanisms to tighten and unlock the plugs and sockets are cumbersome, making the connection or disconnection between the main unit and peripherals inconvenient and impacting work efficiency. Summary of the Invention

[0004] This application provides a connector structure and a medical device. The connector structure is easy to operate and simple in structure. It can lock or unlock at the same time as the insertion and removal operation, which simplifies the connection or disconnection operation between the medical device host and the peripheral device and improves the work efficiency of the operator.

[0010] The locking and unlocking structure includes a second connector and a limiting member. The second connector is adapted to move along a first direction to lock and unlock with the first connector, and the limiting member has a first position and a second position that limit and cooperate with the second connector.

[0011] When the plug is inserted into the socket, the limiting member moves from the first position to the second position, and the second connector locks with the first connector; when the plug is removed from the socket, the limiting member moves from the second position to the first position, and the second connector unlocks with the first connector.

[0012] Optionally, the connector structure includes a first elastic element and a mounting base, the mounting base being disposed on the socket, the limiting element being slidably disposed on the mounting base along a second direction, and the two ends of the first elastic element being connected to the mounting base and the limiting element respectively;

[0013] When the plug is inserted into the socket, the limiting member compresses the first elastic member and moves to the second position. When the plug is removed from the socket, the first elastic member rebounds to reset the limiting member to the first position.

[0014] Optionally, the second connector includes a first groove and a second groove that are interconnected; when the limiting member is in the first position, the limiting member is located in the first groove and engaged with the first groove; when the limiting member is in the second position, the limiting member is located in the second groove and engaged with the second groove.

[0015] Optionally, the limiting member has a protrusion and a recess that are connected to each other, and the size of the first recess is larger than the size of the second recess; when the limiting member is in the first position, the protrusion engages with the first recess; when the limiting member is in the second position, the limiting member compresses the first elastic member to engage the recess with the second recess.

[0016] Optionally, the connector structure includes a second elastic element, one end of which is connected to the mounting base and the other end of which is connected to the second connector.

[0017] When the limiting member is in the first position, the second connecting member compresses the second elastic member; when the limiting member is in the second position, the second elastic member rebounds and drives the second connecting member to move along the first direction to reset.

[0018] Optionally, the outer peripheral wall of the first connector is provided with a locking groove, the limiting member moves from the first position to the second position, the second connector moves along the first direction, and the first connector passes through the first groove and engages with the second connector.

[0019] Optionally, the locking and releasing structure is provided in two sets, with the two second connectors moving in opposite directions. The number of the first connectors and the second connectors are the same and they are arranged in a one-to-one correspondence. The two second connectors simultaneously engage with the two first connectors to prevent the plug from rotating.

[0020] Optionally, the plug includes a housing and a button, the button being movably disposed in the housing and corresponding to the second connector, pressing the button causing the second connector to compress the second elastic member and move toward the central axis of the socket.

[0021] Optionally, the plug further includes a male terminal, and the socket further includes a female terminal, wherein when the plug is inserted into the socket, the male terminal is inserted into the female terminal to achieve an electrical connection.

[0025] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0026] When the socket and plug need to be locked, the plug is moved towards the socket, and the plug and the first connector move synchronously. When the plug is inserted into the socket, the limiting member moves from the first position to the second position, and the first connector gradually moves closer to the second connector, locking the second connector with the first connector. This achieves relative fixation between the first and second connectors, thus locking the plug and socket, reducing the probability of the plug and socket falling off, effectively preventing electric shock accidents, eliminating safety hazards, and ensuring high safety. When the socket and plug need to be unlocked, the plug is moved away from the socket, and the limiting member moves from the second position to the first position, resetting the limiting member. At the same time, the first connector gradually moves away from the second connector, unlocking the second connector from the first connector, thus unlocking the plug and socket. This structure is simple and easy to operate, automatically completing the locking or unlocking work during plugging and unplugging operations. It simplifies the connection or disconnection operation between the medical device host and peripherals, improving the operator's work efficiency. Attached Figure Description

Detailed Implementation

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] This application provides a connector structure and a medical device that can simultaneously lock or unlock the plug and socket during insertion and removal operations, simplifying the connection or disconnection process between the medical device host and peripherals and improving the operator's work efficiency.

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application. Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0042] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0043] Please refer to Figures 1 to 3, which show one embodiment of the connector structure in this application. The connector structure includes a plug 1, a socket 2, and a locking structure 3. The socket 2 is detachably connected to the plug 1. The locking structure 3 is used to lock when the plug 1 and socket 2 need to be plugged in, in order to ensure the reliability of the connection between the plug 1 and the socket 2; and to unlock when the plug 1 and socket 2 need to be separated, so as to facilitate the separation of the plug 1 and the socket 2 and release the electrical connection between the plug 1 and the socket 2.

[0044] Please refer to Figures 1 to 3. The plug 1 includes a housing 13 and a male terminal 11, with the male terminal 11 fixedly mounted on the housing 13. The socket 2 includes a base plate 24 and a female terminal 21, with the female terminal 21 fixedly mounted on the base plate 24. The male terminal 11 and the female terminal 21 are inserted into each other to achieve electrical connection between the plug 1 and the socket 2. In this embodiment, the housing 13 includes a cover and an end cap. The end cap is fixedly mounted on the cover by bolts. The cover and the end cap together form a cavity to accommodate the male terminal 11 and other electronic components.

[0045] Furthermore, to ensure that the male terminal 11 is accurately and quickly inserted into the female terminal 21 to achieve electrical connection, the plug 1 is provided with multiple guide posts 12, and the socket 2 is provided with multiple positioning holes 22 for the guide posts 12 to be inserted. The multiple guide posts 12 are arranged one-to-one with the multiple positioning holes 22, and the male terminal 11 is aligned with the female terminal 21. In this embodiment, the guide posts 12 are vertically arranged, and the length of the guide posts 12 is greater than the length of the male terminal 11. When the plug 1 gradually approaches the socket 2, the guide posts 12 first contact the positioning holes 22 on the socket 2 and begin to guide the plug 1 to move in the vertical direction. The multiple guide posts 12 are simultaneously inserted into the positioning holes 22. At this time, the male terminal 11 is accurately aligned with the female terminal 21, which facilitates the insertion of the male terminal 11 and the female terminal 21 to achieve electrical connection. The guide post 12 can play a preliminary position correction role, limiting the relative angle range of the plug 1 and socket 2 before they come into contact, ensuring that the two parts can only move along a specific path, avoiding the problem that the male terminal 11 cannot be properly inserted into the female terminal 21 due to angle deviation. With the guidance of the guide post 12, even if the user's feel is not precise, the user can accurately align the plug 1 with the socket 2 with the help of the physical structure. The user does not need to spend too much effort to adjust the position and can easily complete the connection operation, improving work efficiency and reducing potential risks.

[0046] The plug 1 includes a first connector 17, and the locking / unlocking structure 3 includes a second connector 32 and a limiting member 34. The first connector 17 is fixedly disposed on the end face of the plug 1 facing the socket 2. The second connector 32 is adapted to move along a first direction to achieve locking and unlocking with the first connector 17. The limiting member 34 has a first position and a second position that limit and cooperate with the second connector 32. When the plug 1 is inserted into the socket 2, the limiting member 34 moves from the first position to the second position, and the second connector 32 locks with the first connector 17. When the plug 1 leaves the socket 2, the limiting member 32 moves from the second position to the first position, and the second connector 32 unlocks with the first connector 17.

[0047] Understandably, when the socket 2 and plug 1 need to be locked, the plug 1 is moved towards the socket 2, and the plug 1 and the first connector 17 move synchronously. When the plug 1 is inserted into the socket 2, the limiting member 34 moves from the first position to the second position, and the first connector 17 gradually moves closer to the second connector 32. The second connector 32 locks with the first connector 17, achieving relative fixation between the first connector 17 and the second connector 32. This locks the plug 1 and socket 2, reducing the probability of the plug 1 falling off the socket 2, effectively preventing electric shock accidents, and eliminating safety hazards. Furthermore, it offers high security. When socket 2 and plug 1 need to be unlocked, the plug 1 is moved away from socket 2, and the limiting member 34 moves from the second position to the first position, causing the limiting member 34 to reset. At the same time, the first connecting member 17 gradually moves away from the second connecting member 32, thereby unlocking the second connecting member 32 from the first connecting member 17, thus unlocking the plug 1 and socket 2. This structure is simple and easy to operate. It can automatically complete the locking or unlocking work while plugging and unplugging, simplifying the connection or disconnection operation between the medical device host and peripherals and improving the work efficiency of the operator.

[0048] Please refer to Figures 2 and 3. Specifically, the first connector 17 is vertically arranged, and its outer peripheral wall is provided with a locking groove 171 for engaging with the second connector 32. The second connector 32 includes a locking portion 321 and a pressing portion 322. The pressing portion 322 is disposed on one side of the locking portion 321 and is integrally formed with the locking portion 321. In this embodiment, the connector structure includes a mounting base 23, which is fixedly disposed on the socket 2. The mounting base 23 is provided with a guide groove 231 along a first direction. The locking portion 321 is slidably disposed in the guide groove 231, and the pressing portion 322 is vertically arranged and located on one side of the mounting base 23.

[0049] To enable the second connector 32 to move along the first direction, the connector structure includes a second elastic member 35. One end of the second elastic member 35 is connected to the mounting base 23, and the other end is connected to the second connector 32; that is, the second elastic member 35 is disposed between the pressing part 322 and the mounting base 23. When the limiting member 34 is in the first position, the second connector 32 compresses the second elastic member 35; when the limiting member 34 is in the second position, the second elastic member 35 rebounds, causing the second connector 32 to move along the first direction to reset. Understandably, the pressing part 322 moves toward the mounting base 23 to compress the second elastic member 35, and simultaneously drives the locking part 321 to slide along the guide groove 231. At this time, the second connecting member 32 is in the first position for limiting engagement through the limiting member 34. The second elastic member 35 rebounds to drive the pressing part 322 away from the mounting base 23, and simultaneously drives the locking part 321 to move synchronously. At this time, the second connecting member 32 is in the first position for limiting engagement through the limiting member 34, so that the second connecting member 32 is suitable for moving along the first direction.

[0050] When plug 1 is inserted into socket 2, the second connector 32 locks with the first connector 17. At this time, the locking groove 171 of the first connector 17 and the snap-fit ​​part 321 snap into each other. When plug 1 leaves socket 2, a force is applied to the pressing part 322. The pressing part 322 moves toward the mounting base 23 to compress the second elastic member 35, and simultaneously drives the snap-fit ​​part 321 to slide along the guide groove 231. At this time, the locking groove 171 and the snap-fit ​​part 321 disengage from each other, thereby releasing the lock between the first connector 17 and the second connector 32. After plug 1 is completely removed from socket 2, the force applied to the pressing part 322 is released. Under the rebound force of the second elastic member 35, the second elastic member 35 drives the pressing part 322 to move away from the mounting base 23, and simultaneously drives the snap-fit ​​part 321 to move synchronously to reset.

[0051] Please refer to Figures 2, 5, and 7. To facilitate operation of the second connector 32, the plug 1 also includes a button 14. The button 14 is movably disposed on the housing 13 and corresponds to the second connector 32. Pressing the button 14 causes the second connector 32 to compress the second elastic member 35 and move towards the central axis of the socket 2. In this embodiment, to reset the button 14, the housing 13 is also provided with a reset member 15. The reset member 15 is preferably a spring, and it is fixedly disposed on the cover by a mounting member 16 so that the reset member 15 is fixed relative to the housing 13. Specifically, one end of button 14 is provided with a protrusion 141. The reset member 15 is sleeved on the outer peripheral wall of the protrusion 141 and fixedly connected to the protrusion 141. Pressing button 14 causes button 14 to press against pressing part 322. The button 14 applies force to pressing part 322. At this time, the protrusion 141 compresses the end of reset member 15. At the same time, button 14 presses against pressing part 322 and moves toward mounting base 23, and second elastic member 35 is compressed. After releasing the press of button 14, reset member 15 rebounds, causing the end of reset member 15 to drive the protrusion 141 to move synchronously, so that button 14 is reset, making it easy to unlock the button 14 by pressing it again.

[0052] Referring to Figures 4 and 5, to enable the movement of the limiting member 34 between the first and second positions, the connector structure further includes a first elastic member 33. The limiting member 34 is slidably disposed on the mounting base 23 along the second direction, and both ends of the first elastic member 33 are connected to the mounting base 23 and the limiting member 34, respectively. When the plug 1 is inserted into the socket 2, the limiting member 34 compresses the first elastic member 33 and moves to the second position. When the plug 1 is removed from the socket 2, the first elastic member 33 rebounds to reset the limiting member 34 to the first position. In this embodiment, the first direction is perpendicular to the second direction, the first direction is the width direction of the base plate, and the second direction is the height direction of the base plate. Understandably, when the plug 1 moves toward the socket 2, the plug 1 gradually presses against the limiting member 34, causing the limiting member 34 to slide relative to the base plate 24 along the second direction, aiming to compress the first elastic member 33 and move to the second position; when the socket 2 and the plug 1 need to be unlocked, the plug 1 gradually moves away from the limiting member 34, releasing the compression of the first elastic member 33 by the limiting member 34, and the first elastic member 33 rebounds so that the limiting member 34 moves toward the plug until it is reset to the first position.

[0053] Furthermore, to achieve the limiting engagement between the limiting member 34 and the second connecting member 32 in the first and second positions, the second connecting member 32 includes a first groove 3211 and a second groove 3212 that are interconnected. When the limiting member 34 is in the first position, the limiting member 34 is located within and engaged with the first groove 3211. When the limiting member 34 is in the second position, the limiting member 34 is located within and engaged with the second groove 3212. Specifically, the limiting member 34 has a protrusion 341 and a recess 342 that are interconnected. The size of the first groove 3211 is larger than the size of the second groove 3212. When the limiting member 34 is in the first position, the protrusion 341 engages with the first groove 3211. When the limiting member 34 is in the second position, the limiting member 34 compresses the first elastic member 33 to engage the recess 342 with the second groove 3212.

[0054] Understandably, when the plug 1 is away from the socket 2, the limiting member 34 is in the first position. At this time, the protrusion 341 of the limiting member 34 is located in the first groove 3211 and engages with the first groove 3211. The limiting member 34 restricts the movement of the engaging part 321, and the pressing part 322 is in a state of compressing the second elastic member 35. When the plug 1 gradually approaches the socket 2, the plug 1 presses against the limiting member 34, and the limiting member 34 moves downward to compress the first elastic member 33. The limiting member 34 gradually moves from the first position to the second position, and the part of the limiting member 34 that presses against the engaging part 321 gradually moves upward until it reaches the groove 342. Since the outer diameter of the protrusion 341 is larger than the outer diameter of the groove 342, the first groove 3211... The size is larger than that of the second groove 3212. When the limiting member 34 and the second connecting member 32 switch their limiting engagement, it provides movement space for the locking part 321. Under the action of the rebound force of the second elastic member 35, the locking part 321 moves synchronously with the pressing part 322 in the first direction to realize the switching between the first groove 3211 and the second groove 3212. When the plug 1 is inserted into the socket 2, the limiting member 34 is in the second position, the recess 342 is located in the second groove 3212 and is locked with the second groove 3212. At the same time, the first connecting member 17 passes through the first groove 3211 and is locked with the second connecting member 35. That is, the locking groove 171 of the first connecting member 17 is locked with the second groove 3212, thereby realizing the locking between the plug 1 and the socket 2.

[0055] Please refer to Figures 5 and 7. To enhance the locking effect between the plug 1 and the socket 2, in this embodiment, two sets of locking and releasing structures 3 are provided, symmetrically arranged along the central axis of the base plate 24. The two second connecting members 32 move in opposite directions, and the number of first connecting members 17 and second connecting members 32 are the same and correspond one-to-one. The two second connecting members 32 simultaneously engage the two first connecting members 17 to prevent the plug 1 from rotating. Correspondingly, two buttons 14 are provided, and the two buttons 14 are respectively located on both sides of the reset member 15. When it is necessary to unlock the plug 1 and socket 2, press the buttons 14 on both sides of the plug 1 simultaneously so that the buttons 14 contact and press against the pressing part 322. The buttons 14 move closer to each other and compress the two ends of the reset member 15. At this time, the two second connecting members 32 move towards each other, and the two first connecting members 17 move from the second position to the first position at the same time. The second connecting members 32 and the first connecting members 17 are unlocked. After the button 14 is released, the reset member 15 springs back to reset so that the two protrusions 141 move away from each other so that the button 14 is reset. At this time, the two second connecting members 32 move away from each other.

[0056] The following describes in detail the locking process between plug 1 and socket 2. Please refer to Figures 5 and 6. When plug 1 moves towards socket 2, plug 1 and first connector 17 move synchronously. Plug 1 gradually presses against the upper end of limiting member 34. Limiting member 34 moves along the first direction to gradually compress the first elastic member 33. Limiting member 34 moves from the first position to the second position. At this time, the state in which the protrusion 341 is engaged with the first groove 3211 gradually moves upward to the state in which the concave part 342 is engaged with the second groove 3212. Under the rebound force of the first elastic member 33, the first groove 3211 moves synchronously with the pressing part 322. At this time, the first connector 17 passes through the first groove 3211, and the locking groove 171 engages with the second connector 32. The first connector 17 and the second connector 32 are relatively fixed, thereby achieving the locking between plug 1 and socket 2, and thus enhancing the stability of the electrical connection between male terminal 11 and female terminal 21.

[0057] The following describes in detail the unlocking process of plug 1 and socket 2. Please refer to Figures 7 and 8. First, press the buttons 14 on both sides of plug 1 so that the buttons 14 contact and press against the pressing part 322. The pressing part 322 compresses the second elastic member 35 and moves towards the mounting base 23, so that the locking part 321 moves synchronously to drive the first groove 3211 to disengage from the slot 3421. At the same time, operate plug 1 to move away from socket 2. Plug 1 gradually releases the pressure on the limiting member 34. The first elastic member 33 drives the limiting member 34 to move upward to reset, so that the limiting member 34 moves from the second position to the first position. The protrusion 341 moves upward synchronously to gradually approach the first groove 3211 and then locks against the first groove 3211. Continue to operate plug 1 to move away from socket 2 to separate plug 1 from socket 2, thereby unlocking plug 1 and socket 2, and at the same time, disconnecting the electrical connection between male terminal 11 and female terminal 21.

[0058] Referring to Figure 9, this application also discloses a medical device, which includes a host, peripherals, and a connector structure as described above. A plug 1 is connected to the peripherals via a connecting cable, and a socket 2 is fixedly mounted on the host. In this embodiment, the socket 2 is fixed to the host by bolts. The plug 1 and socket 2 are electrically connected to achieve signal transmission between the peripherals and the host. The connector structure of this application is convenient to operate and simple in structure. During insertion and removal operations, the locking or unlocking of the plug 1 and socket 2 can be completed simultaneously, simplifying the connection or disconnection process between the medical device host and peripherals, improving the operator's work efficiency, effectively preventing electric shock accidents, eliminating safety hazards, and ensuring high safety.
