Technical Field

[0001] The present application relates to the technical field of medical device connection, and in particular to an anti-falling structure of a magnetic suction head. Background Art

[0002] In the field of medical device connection technology, magnetic suction heads have received widespread attention due to their convenience and efficiency. However, with the popularization of its application, some problems of magnetic suction heads have gradually become prominent, especially the stability of the connection between the magnet and the plug body. The outer surface of the traditional magnetic suction head design is smooth, and there is no strong interference force between the plastic and the magnet during injection molding. When the male and female parts of the finished product attract each other, when the external connection power supply needs to be pulled away from the magnet, the magnet and the plug body rubber core will fall off and separate, which not only affects the continuity and stability of the connection, but may also cause safety hazards to medical equipment.

[0003] At present, the industry has tried to deal with this problem by using stronger adhesive materials and other methods to enhance the bonding force between the magnet and the plug body. However, these solutions are often difficult to maintain continuous effectiveness in long-term use due to the aging of the adhesive material and the influence of external forces. The magnetic suction head is easy to fall off the plug body, and the stability and reliability of the overall connection of the magnetic suction head are low. Summary of the invention

[0004] In order to improve the stability and reliability of the overall connection of the magnetic suction head, the present application provides an anti-falling structure of the magnetic suction head.

[0005] The present application provides a magnetic suction head anti-falling structure, which adopts the following technical solution:

[0006] A magnetic suction head anti-falling structure, comprising:

[0009] By adopting the above technical solution, the outer side of the magnetic attraction component is set to a step shape, so that when the rubber core component is sleeved on the plug socket and the magnetic attraction component, one end of the rubber core component can be connected to the step surface of the magnetic attraction component, thereby increasing the bonding area and interference force between the rubber core component and the magnetic attraction component, thereby improving the connection stability between the magnetic attraction component and the plug body, effectively reducing the occurrence of the magnetic attraction component falling off the plug body, and improving the stability and reliability of the overall connection of the magnetic attraction head.

[0011] By adopting the above technical solution, the shell protects the contact terminals and provides certain waterproof and dustproof functions; the rubber core component not only mechanically connects the magnetic suction component and the shell, but also plays an electrical insulating role, reduces the possibility of short circuit of the contact terminals, and improves the correctness of the current path. At the same time, the magnetic connection part is coordinated with the electrical connection part to enhance the integration of the overall structure, reduce the possibility of power failure due to loose contact terminals, improve safe and reliable electrical connection, and provide a safe, stable and easy-to-use power connection structure for external power connection.

[0012] Preferably, the shell includes a connecting portion and a fixing portion, the connecting portion is connected to the magnetic attraction component, the connecting portion and the fixing portion are connected in a step shape, and the step surface formed by the connecting portion and the fixing portion is connected to the magnetic attraction component.

[0016] Preferably, the connecting portion and the fixing portion are integrally formed.

[0017] By adopting the above technical solution, the traditional assembly method may introduce connection defects such as looseness, misalignment or leakage. The one-piece molding makes the connecting part and the fixing part manufactured as a whole. There is no seam between the connecting part and the fixing part, which reduces the structural weaknesses caused by poor connection, enhances the overall structural strength of the shell, and reduces the possibility of the magnetic part driving the connecting part away from the fixing part when the magnetic part is pulled.

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses an anti-falling structure of a magnetic suction head.

[0035] Reference Figure 1 and Figure 2 , an anti-falling structure of a magnetic head, comprising a magnetic component 1 and a plug body 2, the extended cross-section of the magnetic component 1 is circular, the outer side of the magnetic component 1 is set in a step shape, the extended cross-sections at both ends of the magnetic component 1 are two circles with concentric centers and different areas, the plug body 2 comprises a plug socket 21 and a rubber core component 22, the plug socket 21 is fixed to the side with a larger extended cross-sectional area of ​​the magnetic component 1, the outer wall of the plug socket 21 is connected to the rubber core component 22, the rubber core component 22 is tubular, the rubber core component 22 is sequentially sleeved on the plug socket 21 and the magnetic component 1, and one end of the rubber core component 22 in the sleeve direction is tightly connected to the step surface of the magnetic component 1.

[0036] When the magnetic head of the external connection plug is adsorbed to the magnetic component 1, when the magnetic head is pulled away from the magnetic component 1, the magnetic head adsorbs the magnetic component 1, so that the magnetic component 1 generates a pulling force away from the plug socket 21. When used for a long time, the magnetic component 1 is easy to separate from the plug. The rubber core 22 is sleeved on the outer wall of the plug socket 21 to wrap the plug socket 21 so that the plug socket 21 and the rubber core 22 are tightly fitted. The rubber core 22 is sleeved on the magnetic component 1, and one end of the rubber core 22 is located at the magnetic component. The rubber core component 22 is injection molded at the step surface of the magnetic component 1, so that the rubber material can fully cover and tightly combine with the step position of the magnetic component 1, increase the combination area and interference force between the rubber core component 22 and the magnetic component 1, when the magnetic component 1 is pulled, the rubber core component 22 interferes with the movement of the magnetic component 1, reduces the possibility of the magnetic component 1 being separated from the plug socket 21, enhances the connection stability between the magnetic component 1 and the plug body 2, and reduces the possibility of the magnetic component 1 falling off due to external force during use.

[0037] The plug socket 21 includes a shell 211 and a contact terminal 212. The rubber core member 22 is sleeved on the shell 211, and the side wall of the shell 211 is fixed to the inner wall of the rubber core member 22. One side of the shell 211 is fixed to the magnetic attraction member 1. The contact terminal 212 is inserted into the shell 211. The contact terminal 212 is exposed to the external environment and is used to make an electrical connection with an external power supply. In application, the contact terminal 212 can be sheet-shaped, hole-shaped or needle-shaped.

[0038] When the male and female terminals of the finished products attract each other, the external connection plug is inserted into the shell 211, and the external connection plug is electrically connected to the contact terminal 212, so that the external connection plug is energized and the device connected to the external connection plug is operated. The shell 211 is provided, and the shell 211 has a protective effect on the contact terminal 212, provides a certain waterproof and dustproof function, reduces the possibility of short circuit of the contact terminal 212, and improves the correctness of the current path. At the same time, the magnetic connection part 2111 is coordinated with the electrical connection part 2111 to enhance the integration of the overall structure, reduce the possibility of power failure due to loose contact terminal 212, improve safe and reliable electrical connection, and provide a safe, stable and easy-to-use power connection structure for external power connection.

[0039] Furthermore, the shell 211 includes a connecting portion 2111 and a fixing portion 2112, the connecting portion 2111 is fixed to the magnetic component 1, and the connecting portion 2111 and the fixing portion 2112 are fixed in a step-like manner, the extended cross-sectional area of ​​the connecting portion 2111 is smaller than the extended cross-sectional area of ​​the fixing portion 2112, and the rubber core 22 is sleeved along the outer wall of the fixing portion 2112 to the step surface between the connecting portion 2111 and the fixing portion 2112, and the rubber core 22 is wrapped around the fixing portion 2112. This step-like connection makes the contact area between the shell 211 and the magnetic component 1 larger and the connection more stable. At the same time, the step surface formed by the connection between the connecting portion 2111 and the fixing portion 2112 is also tightly connected to the magnetic component 1, further enhancing the overall stability.

[0040] The outer wall of the connecting portion 2111 is tightly fixed to the groove wall of the mounting groove 11, and the magnetic attraction member 1 is fixedly connected to the step surface of the connecting portion 2111 and the fixing portion 2112. The output end of the contact terminal 212 is sequentially inserted and fixed to the fixing portion 2112 and the connecting portion 2111. The output end of the contact terminal 212 is located within the groove range of the mounting groove 11, and the external connection plug can be electrically connected to the contact terminal 212. At the same time, the connecting portion 2111 is inserted into the mounting groove 11, so that the side wall of the connecting portion 2111 is tightly connected to the groove wall of the mounting groove 11, further increasing the connection area between the magnetic attraction member 1 and the shell 211, increasing the friction between the two, further reducing the possibility of the magnetic attraction member 1 falling off from the plug socket 21 when the magnetic attraction member 1 is pulled, and improving the stability and reliability of the overall connection of the magnetic attraction head.

[0041] The extended cross-sectional area of ​​the side of the magnetic attraction component 1 close to the fixed part 2112 is larger than the extended cross-sectional area of ​​the side of the fixed part 2112 close to the connecting part 2111. The end of the magnetic attraction component 1 close to the fixed part 2112 forms an annular protrusion at the junction of the connecting part 2111 and the fixed part 2112. When the rubber core component 22 is injection molded, the rubber core component 22 fits the magnetic component and the fixed part 2112. The inner wall of the rubber core component 22 is provided with an annular groove that matches and fits the annular protrusion, which further enhances the interference force of the rubber core component 22 on the magnetic attraction component 1 and reduces the possibility of the magnetic component detaching from the shell 211.

[0042] In order to reduce the possibility of the connection part 2111 following the magnetic part to separate from the fixed part 2112 and the rubber core part 22, the connection part 2111 and the fixed part 2112 are made by an integrated molding process. There is no seam between the connection part 2111 and the fixed part 2112, which reduces connection defects such as looseness, misalignment or leakage, and enhances the overall structural strength of the housing 211, so that when the magnetic attraction part 1 is pulled, it is difficult for the magnetic attraction part 1 to drive the connection part 2111 to separate from the fixed part 2112.

[0043] The outer wall of the fixed part 2112 is fixedly connected with an anti-rotation component 3, and the anti-rotation component 3 is arranged in a convex shape on the outer side of the fixed part 2112. The rubber core component 22 is fitted and fixed to the anti-rotation component 3, which reduces the possibility of the rubber core component 22 being easy to rotate when connected to the fixed part 2112, thereby reducing the possibility of the fixed part 2112 loosening and causing the magnetic suction component 1 to be unstable, thereby improving the stability and reliability of the overall connection of the magnetic suction head.

[0044] The plug socket 21 is also provided with a positioning mechanism. Specifically, the positioning mechanism includes a guide groove 4 opened in the connecting portion 2111 away from the fixing portion 2112. The guide groove 4 is located in the mounting groove 11. The guide groove 4 is equidistantly arranged circumferentially along the inner groove wall of the mounting groove 11. The guide groove 4 provides a clear insertion path for the external connection plug, so that the external connection plug can smoothly make electrical contact with the contact terminal 212 along a predetermined direction, thereby simplifying the connection process of the plug and greatly improving the accuracy and speed of the connection.

[0045] Further, see Figure 3 An insertion mark is also provided on the magnetic member 1. In the present embodiment, the insertion mark is a beveled surface 5 provided at one end of the magnetic member 1 away from the fixing portion 2112. The extended cross-section of the magnetic member 1 is circular. The beveled surface 5 provides a different point for the magnetic member, which provides guidance when the external connection plug is connected to the contact terminal 212, thereby reducing the possibility of reverse insertion. The user can intuitively determine the insertion direction and position of the plug, thereby further reducing the possibility of errors when connecting the external connection plug and improving the safety of the magnetic head socket.

[0046] The implementation principle of the anti-falling structure of a magnetic head in an embodiment of the present application is as follows: when it is necessary to unplug the external connection plug adsorbed on the magnetic part, the external connection plug applies a pulling force to the magnetic part 1, so that the magnetic part 1 tends to move away from the fixing part 2112. The outer side of the magnetic part 1 is arranged in a step shape, and one end of the rubber core part 22 is sleeved on the step surface of the magnetic part 1. When the magnetic part is pulled, the rubber core part 22 blocks the moving trend direction of the magnetic part 1, thereby reducing the possibility of the magnetic part 1 falling off the plug socket 21. Furthermore, an annular protrusion is formed at the junction of the connecting part 2111 and the fixing part 2112 at one end of the magnetic part 1 close to the fixing part 2112, and the groove wall of the annular groove fits with the annular protrusion, thereby further enhancing the interference force of the rubber core part 22 on the magnetic part 1, reducing the possibility of the magnetic part detaching from the shell 211, and improving the stability and reliability of the overall connection of the magnetic head.

[0047] The above are all preferred embodiments of the present application.
