[0026] Please see Figure 1 , Figure 7 and Figure 11 The present invention provides a connector 100 for use in a medical device 1000. The medical device 1000 includes an accessory 300 and a monitoring device 200. The connector 100 includes a plug 10 and a socket 20. One of the plug 10 and the socket 20 is located in the accessory 300, and the other is located in the monitoring device 200.

[0027] The plug 10 includes a first terminal 11 and a frame 12. The socket 20 includes a mating part 21, which is provided with a second terminal 211. The frame 12 is provided with a insertion cavity 124 with an opening 125 on one side. The first terminal 11 is disposed in the insertion cavity 124 and connected to the frame 12. The first terminal 11 is used to electrically connect with the second terminal 211 to transmit electrical signals. The frame 12 is used to interference fit with the mating part 21 and provide insertion and extraction force during the insertion and extraction of the connector 100.

[0028] The skeleton 12 surrounds the wall 121 with the insertion cavity 124 and has a notch 122. The notch 122 is used to deform the skeleton 12 under the action of external force to reduce the attenuation rate of the insertion and extraction force of the skeleton 12 during the insertion and extraction process of the connector 100.

[0029] In the connector 100 described above, the skeleton 12 surrounds the wall 121 of the insertion cavity 124 and has a notch 122. The notch 122 is used to deform the skeleton 12 under the action of external force to reduce the wear of the skeleton 126 and the mating part 212, thereby reducing the decay rate of the insertion and extraction force and improving the service life of the connector 100.

[0030] Specifically, please combine Figure 11 Medical device 1000 refers to an electronic device used for diagnosing, monitoring, treating, or supporting human physiological functions. Medical device 1000 includes accessories 300 and monitoring equipment 200. Accessories 300 and monitoring equipment 200 are electrically connected via connector 100 for electrical signal exchange. Accessories 300 refers to components that come into contact with or indirectly act on the patient. Monitoring equipment 200 refers to the main control unit in medical device 1000, used to receive, analyze, process, display, and record signals transmitted from accessories 300.

[0031] Connector 100 includes a plug 10 and a socket 20. One of the plug 10 and the socket 20 is located in accessory 300, and the other is located in monitoring device 200. Figure 1 , Figure 2 and Figure 11 In the middle, plug 10 is located in accessory 300, and socket 20 is located in monitoring equipment 200.

[0032] The plug 10 includes a frame 12 and a first terminal 11, and the socket 20 includes a mating part 21, which is provided with a second terminal 211. The first terminal 11 and the second terminal 211 are conductive elements, and the first terminal 11 and the second terminal 211 can contact each other to form an electrical connection, so as to realize the transmission of electrical signals.

[0033] The frame 12 serves as the supporting body for the plug 10, capable of withstanding mechanical loads during insertion and removal. The frame 12 encloses a mating cavity 124, a hollow internal structure designed to accommodate the mating portion 21 of the socket 20. The mating portion 21 is the part where the socket 20 mates with the plug 10. The mating cavity 124 and the mating portion 21 are matched in shape, and the connection between the frame 12 and the mating portion 21 is achieved through an insertion action. The frame 12 provides insertion and removal force during insertion and removal. Insertion and removal force refers to the resistance caused by the interference fit between the frame 12 and the mating portion 212 during insertion and removal. The magnitude of the insertion and removal force directly affects the smoothness of insertion and removal and the reliability of the connection of the connector 100: excessive insertion and removal force may lead to operational difficulties or structural wear, while insufficient force may cause poor contact or loosening.

[0034] It should be noted that the insertion and removal process of connector 100 refers to the process of inserting plug 10 into socket 20 to achieve mating, and the process of pulling plug 10 out of socket 20 to achieve separation.

[0035] The enclosure 121 of the skeleton 12 refers to the wall surrounding the forming of the insertion cavity 124. During use, if the skeleton 12 is too rigid or has a closed structure, it is difficult to produce outward expansion deformation, resulting in greater resistance during insertion and removal. This intensifies wear between the skeleton 126 and the mating part 21, accelerating the decay of the insertion and removal force provided by the skeleton 12 and affecting the lifespan of the connector 100. Therefore, in this embodiment, the enclosure 121 is provided with a notch 122. When external forces (including insertion and removal forces) act on the connector 100, the area where the notch 122 is located can produce controllable elastic deformation to release some stress, effectively reducing the overall rigidity of the enclosure 121 and making it easier to produce outward expansion deformation. This reduces the resistance between the skeleton 126 and the mating part 212 during insertion and removal. As the resistance decreases, the friction also decreases, resulting in less wear between the skeleton 126 and the mating part 212, reducing the decay rate of the insertion and removal force, and improving the lifespan of the connector 100.

[0036] It should be noted that the insertion and extraction force is inversely proportional to the number of insertion and extraction cycles performed on connector 100. The more insertion and extraction cycles, the lower the insertion and extraction force. The insertion and extraction force decay rate refers to the rate at which the insertion and extraction force gradually decreases as the number of insertion and extraction cycles increases. Under the premise of the same number of insertion and extraction cycles, a greater insertion and extraction force decay rate indicates that the wear of connector 100 is more severe and the lifespan of connector 100 is shorter. Conversely, a smaller insertion and extraction force decay rate indicates that connector 100 can maintain relatively stable insertion and extraction performance and structural strength after multiple insertions and extractions, and the lifespan of connector 100 is longer.

[0037] Please combine Figure 9 , Figure 9 A graph showing the relationship between insertion / removal force and the number of insertions / removals is provided. The solid line represents the relationship between insertion / removal force and the number of insertions / removals for the connector 100 in this embodiment of the invention. The dashed line represents the relationship between insertion / removal force and the number of insertions / removals for the comparative connector, which does not have a notch 122. It can be seen from the graph that as the number of insertions / removals increases, the rate of decrease in insertion / removal force of the connector 100 in this embodiment of the invention is less than the rate of decrease in insertion / removal force of the comparative connector.

[0038] In addition, the notch 122 also has a recovery function. After the external force is removed, it will elastically return to its original shape, so that the insertion and extraction force is maintained at a relatively stable level, thereby reducing the tendency of the insertion and extraction force to decrease rapidly with the increase of the number of insertions and extractions.

[0039] Optionally, the present invention does not limit the shape and number of notches 122. The number of notches 122 can be single or multiple, and the shape of notches 122 can be straight, arc or other arbitrary curved form.

[0040] The number of first terminals 11 and second terminals 211 is equal. Optionally, the number of both first terminals 11 and second terminals 211 does not exceed 7.

[0041] The materials of the skeleton 12 include, but are not limited to, acrylonitrile-butadiene-styrene copolymer (ABS), polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), etc.

[0042] The materials of socket 20 include, but are not limited to, metals, acrylonitrile-butadiene-styrene copolymer (ABS), polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), etc.

[0043] In some implementations, please refer to Figures 1 to 4 The notch 122 connects the insertion cavity 124 and the outside of the skeleton 12, and one end of the notch 122 is connected to the opening 125.

[0044] In the above embodiments, the deformability of the skeleton 12 is further improved, so as to further reduce the wear of the skeleton 12 during the insertion and removal process and improve the service life of the connector 100.

[0045] Specifically, the notch 122 penetrates the thickness of the wall 121 of the frame 12, thereby connecting the insertion cavity 124 and the outside of the frame 12. One end of the notch 122 is connected to the opening 125 of the insertion cavity 124. When the plug 10 is inserted into the mating part 21 of the socket 20, the wall 121 of the frame 12 will undergo a slight elastic deformation that expands outward under the action of external force. The notch 122 provides a release path for the deformation of the wall 121 by connecting the inner and outer spaces, thereby making the deformation of the wall 121 more compliant and avoiding local stress concentration.

[0046] The present invention does not limit the position of the end of the notch 122 away from the opening 125 of the insertion cavity 124. Optionally, the notch 122 can be arranged in a straight line along the axial direction of the skeleton 12, or it can be arranged in an arc or ring around the wall 121 of the skeleton 12 to adapt to different structural designs and stress requirements.

[0047] In some implementations, please refer to Figures 1 to 4 The notch 122 extends along the insertion / removal direction of the connector 100.

[0048] In the above embodiments, the deformability of the skeleton 12 is further improved, so as to further reduce the wear of the skeleton 12 during the insertion and removal process and improve the service life of the connector 100.

[0049] Specifically, the insertion and removal directions of connector 100 refer to the direction in which plug 10 is inserted into socket 20 and the direction in which plug 10 is pulled out of socket 20. During insertion and removal, the insertion and removal force is applied in the opposite direction of insertion and removal, and notch 122 extends along the insertion and removal direction, so that the stress perpendicular to the insertion and removal direction of skeleton 12 during insertion and removal can be evenly released along both sides of notch 122, thereby providing a better elastic release path, giving skeleton 12 better compliance and strain buffering performance during insertion and removal, thereby further improving the deformation capacity of skeleton 12, further reducing wear of skeleton 12 during insertion and removal, and improving the service life of connector 100.

[0050] In some implementations, please refer to Figure 4 The end of the notch 122 away from the opening 125 has a rounded corner structure.

[0051] The above embodiments help maintain the long-term stability of the insertion and extraction force of the connector 100, thereby extending the service life of the connector 100.

[0052] Specifically, the end of the notch 122 furthest from the opening 125 has a rounded corner structure, which makes the transition at the end of the notch 122 smoother. When the frame 12 undergoes elastic deformation under external force during insertion and removal, the end of the notch 122 is a part where stress is concentrated. By adopting a rounded corner structure design, this utility model can effectively reduce the stress concentration effect at this point, making the stress distribution more uniform, thereby avoiding cracks or structural fatigue damage caused by sharp corners.

[0053] In addition, the rounded corner structure can provide better deformation recovery ability during the repeated deformation of the skeleton 12, and to a certain extent prevent the skeleton 12 from undergoing permanent deformation or breakage at sharp corners.

[0054] In some implementations, please refer to Figures 1 to 4 In the direction perpendicular to the enclosure 121, the outer surface of the enclosure 121 is provided with a foolproof groove 123.

[0055] In the above embodiments, damage to the connector 100 caused by misinsertion can be avoided to a certain extent, and the user can quickly locate the insertion direction of the plug 10.

[0056] Specifically, in the direction perpendicular to the enclosure 121, the outer surface of the enclosure 121 is provided with a foolproof groove 123. The foolproof groove 123 is a limiting structure provided on the outer surface of the frame 12, used to match the limiting structure on the socket 20.

[0057] In one embodiment, the socket 20 includes a first mounting hole (not shown), and a mating part 21 is disposed in the first mounting hole and spaced apart from the hole wall of the first mounting hole. The hole wall of the first mounting hole is provided with a protrusion, and the anti-misalignment groove 123 cooperates with the protrusion to limit the insertion and removal position of the plug 10 and the socket 20, and prevent the plug 10 from being inserted in reverse or misaligned during use.

[0058] In some implementations, please refer to Figures 1 to 4 All or part of the notch 122 is located on the bottom wall of the anti-fooling groove 123.

[0059] The above embodiments can reduce the processing difficulty of the skeleton 12.

[0060] Specifically, since the anti-misalignment groove 123 is recessed, all or part of the notch 122 is located at the bottom wall of the anti-misalignment groove 123. On the one hand, it can effectively reduce the weakening of the skeleton 12 and maintain the overall strength and rigidity of the enclosure 121. On the other hand, the recessed space of the anti-misalignment groove 123 can be used to form a notch structure, thereby reducing the processing difficulty and simplifying the molding process.

[0061] It should be noted that in this embodiment, "all or part" can refer to both the structural meaning and the quantitative meaning (e.g., two notches 122, one located inside the anti-mistake groove 123 and the other located opposite the anti-mistake groove 123).

[0062] In some implementations, please refer to Figures 1 to 5 The maximum width of the anti-fooling groove 123 is greater than the maximum width of the notch 122.

[0063] In the above embodiments, the service life of connector 100 is improved while achieving the foolproof function.

[0064] Specifically, since the sidewall of the anti-misplacement groove 123 is used to engage with the protrusion on the socket 20 to achieve anti-misplacement positioning, if the width of the notch 122 is too large, the sidewall of the anti-misplacement groove 123 will be weakened or damaged, which may cause the anti-misplacement function to fail. Therefore, by making the maximum width of the anti-misplacement groove 123 greater than the maximum width of the notch 122, the anti-misplacement function can be guaranteed.

[0065] exist Figure 5 In the implementation, the notch 122 is of equal width and the width of the notch 122 is X1, the anti-mistake groove 123 is of equal width and the width of the anti-mistake groove 123 is X5, X5 > X1.

[0066] In some implementations, please refer to Figures 3 to 8 The inner diameter of the insertion cavity 124 is larger than the outer diameter of the mating part 21. The inner surface of the enclosure 121 is provided with a first limiting part 126, and the outer wall surface of the mating part 21 is provided with a second limiting part 212. The first limiting part 126 and the second limiting part 212 cooperate with each other to limit the relative position between the skeleton 12 and the mating part 21.

[0067] In the above embodiments, wear on the skeleton 12 is reduced, and the service life of the connector 100 is improved.

[0068] Specifically, the inner diameter of the insertion cavity 124 is X7, and the outer diameter of the mating part 21 is X8, where X7 > X8. When the plug 10 is inserted into the socket 20, that is, when the frame 12 and the mating part 21 are connected, there is a certain gap between them, which makes insertion and removal smooth and avoids friction or jamming caused by tight fit to a certain extent, thereby reducing wear on the frame 12 and improving the service life of the connector 100. At the same time, the inner surface of the enclosure 121 is provided with a first limiting part 126, and the outer wall surface of the mating part 21 is provided with a second limiting part 212. The first limiting part 126 and the second limiting part 212 cooperate with each other to accurately limit the relative position between the frame 12 and the mating part 21 and provide insertion and removal force.

[0069] exist Figures 1 to 8In the embodiment shown, the first limiting part 126 can be a groove, and the second limiting part 212 can be a protrusion. The groove and the protrusion fit together to limit the relative position between the skeleton 12 and the mating part 21 and provide insertion and extraction force.

[0070] It is understandable that during the process of inserting the plug 10 into the socket 20, a part of the mating part 21 is first inserted into the insertion cavity 124. At this time, there is a gap fit between the mating part 21 and the inner wall of the insertion cavity 124 until the protrusion on the outer surface of the mating part 21 contacts the inner wall of the insertion cavity 124 and forces the frame 12 to deform. The plug 10 is then inserted until the protrusion fits into the groove. At this time, the frame 12 returns to its original shape under the action of elasticity, and the plug 10 is fully inserted into the socket 20.

[0071] During the process of pulling the plug 10 out of the socket 20, the protrusion gradually disengages from the groove, contacts the inner wall of the insertion cavity 124 and forces the frame 12 to deform. Continue pulling out the plug 10 until the protrusion separates from the inner wall of the insertion cavity 124. At this time, the frame 12 returns to its original shape under the action of elasticity. Continue to pull out the remaining mating part 21 from the insertion cavity 124. The plug 10 has been completely pulled out of the socket 20.

[0072] In some implementations, please refer to Figure 3 and Figure 5 In the insertion / removal direction of connector 100, the depth of notch 122 is X2, the distance between opening 125 and first limiting part 126 is X3, and X2≥X3.

[0073] In the above embodiments, the deformability of the skeleton 12 is further improved, so as to further reduce the wear of the skeleton 12 during the insertion and removal process and improve the service life of the connector 100.

[0074] Specifically, the depth X2 of the notch 122 refers to the dimension of the notch 122 in the insertion and extraction direction, X2≥X3, that is, the position where the notch 122 extends to or beyond the first limiting part 126.

[0075] It is understandable that during the insertion and removal process of the connector 100, the area between the opening 125 and the first limiting part 126 is the area where the force is most concentrated. The notch 122 extends to or beyond the position of the first limiting part 126, which can give the enclosure 121 of this area more elastic deformation space under the action of external force, so as to further reduce the attenuation rate of the insertion and removal force of the skeleton 12 during the insertion and removal process of the connector 100. This can reduce the wear of the skeleton 12 during the insertion and removal process to a certain extent and improve the service life of the connector 100.

[0076] exist Figure 5In the embodiment, the notch 122 and the anti-mistake groove 123 extend in a straight line along the insertion and removal direction. The depth of the notch 122 is X2, and the depth of the anti-mistake groove 123 is X6, where X6 > X2, so that the notch 122 can be located in the recessed area of ​​the anti-mistake groove 123 to ensure the realization of the anti-mistake function.

[0077] In some implementations, please refer to Figure 5 The notch 122 is of equal width, and the width of the notch 122 is X1, where 1 mm ≤ X1 ≤ 2 mm.

[0078] In the above embodiments, the attenuation rate of insertion and extraction force can be reduced as much as possible while ensuring that the connection between the plug 10 and the socket 20 is stable and does not become loose.

[0079] Specifically, the notch 122 has a uniform width structure, meaning that the width of the notch 122 remains consistent along its extension direction, and the two side walls of the notch 122 are parallel to each other. The width of the notch 122 is X1, where 1 mm ≤ X1 ≤ 2 mm. On the one hand, this can, to some extent, prevent the elastic deformation of the frame 12 from being restricted due to the notch 122 being too narrow, thus avoiding operational difficulties or structural wear. On the other hand, it can, to some extent, prevent the enclosure wall 121 from being too strong due to the notch 122 being too wide, thus preventing the plug 10 and socket 20 from becoming loose, resulting in poor contact or detachment.

[0080] In some examples, X1 = 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm or other values ​​that satisfy 1mm≤X1≤2mm.

[0081] Please combine Figure 10 , Figure 10 The graphs showing the relationship between insertion / extraction force and number of insertions / extractions are presented when X1 = 1 mm, 1.5 mm, and 2 mm.

[0082] In some implementations, please refer to Figure 5 During the insertion and removal process of connector 100, connector 100 includes an intermediate state and a final state. When plug 10 is being inserted into or pulled out of socket 20, connector 100 is in the intermediate state. When plug 10 is fully inserted into or fully pulled out of socket 20, connector 100 is in the final state. The minimum distance between the two side walls of notch 122 is X4. In the intermediate state, X4 > X1. In the final state, X4 = X1.

[0083] In the above embodiments, the notch 122 can be restored to its initial width X1 in the final state, thereby ensuring that the connector 100 can maintain a stable structural shape in multiple insertion and removal cycles, and improving the reliability and service life of the connector 100.

[0084] Specifically, during the insertion and removal process of the connector 100, the two side walls of the notch 122 can undergo relative displacement with the elastic deformation of the skeleton 12, thereby reflecting the stress state of the skeleton 12 at different stages.

[0085] In one embodiment, the inner diameter of the insertion cavity 124 is larger than the outer diameter of the mating part 21. The inner surface of the enclosure 121 is provided with a first limiting part 126, and the outer wall surface of the mating part 21 is provided with a second limiting part 212. The first limiting part 126 and the second limiting part 212 cooperate with each other to limit the relative position between the skeleton 12 and the mating part 21. When the connector 100 is in an intermediate state, that is, when the plug 10 is being inserted into or removed from the socket 20, the second limiting part 212 of the mating part 21 contacts the inner wall of the insertion cavity 124 and forces the skeleton 12 to undergo elastic outward expansion deformation. At this time, the two side walls of the notch 122 are pulled apart, and the minimum distance X4 is greater than the initial width X1, indicating that the skeleton 12 is in a state of stress deformation. As the plug 10 continues to be inserted or removed, the second limiting part 212 of the mating part 21 disengages from the inner wall of the insertion cavity 124 or engages with the first limiting part 126, and the skeleton 12 returns to its original shape under its own elasticity. At this time, the connector 100 enters the final state, and the two side walls of the notch 122 return to their initial positions, making X4 equal to X1.

[0086] In some implementations, please refer to Figure 1 and Figure 2 The connector 100 includes a housing 13 that encloses at least a portion of a skeleton 12 and at least a portion of a first terminal 11. The first terminal 11 includes a pin 111 and a second terminal 211 includes a socket 2111. The pin 111 is inserted into the socket 2111 to achieve an electrical connection between the first terminal 11 and the second terminal 211. The outer diameter of the pin 111 is larger than the inner diameter of the socket 2111.

[0087] In the above embodiments, the skeleton 12 and the first terminal 11 can be protected, while improving the electrical connection stability and conductivity of the connector 100.

[0088] Specifically, the outer shell 13 encloses at least a portion of the frame 12 and at least a portion of the first terminal 11, which can protect the frame 12 and the first terminal 11 and reduce the impact of external environmental factors (such as dust, moisture, etc.) on the frame 12 and the first terminal 11.

[0089] The outer diameter of the pin 111 is larger than the inner diameter of the socket 2111. This means that when the pin 111 is inserted into the socket 2111, an interference fit is formed between them. This generates a certain contact pressure during insertion, ensuring reliable electrical contact between the pin 111 and the wall of the socket 2111, thus improving the stability and conductivity of the electrical connection. Simultaneously, the interference fit also provides a certain insertion and extraction force after the plug 10 is connected to the socket 20, further preventing the plug 10 from becoming loose or making poor contact, and improving the reliability of the connector 100 during long-term use.

[0090] In one embodiment, the pin 111 includes a fixing part 112 and a pin part 113. The frame 12 is provided with a second mounting hole 127, and the fixing part 112 is mounted in the second mounting hole 127 to fix the pin part 113. The second terminal 211 includes a socket 2111, and the pin part 113 can be inserted into the socket 2111 to achieve electrical connection.

[0091] The shape of the pin portion 113 includes, but is not limited to, cylindrical, square, or flat. The shape of the socket 2111 includes, but is not limited to, cylindrical, tuning fork, or cantilever beam.

[0092] The materials of the outer shell 13 include, but are not limited to, acrylonitrile-butadiene-styrene copolymer (ABS), polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polyurethane (PU), etc.

[0093] In some implementations, please refer to Figures 1 to 8 The number of first terminal 11 and second terminal 211 are both 2.

[0094] The above embodiments enable the acquisition and transmission of body temperature signals.

[0095] Specifically, in one embodiment, the medical device 1000 can be used to detect body temperature. There are two first terminals 11 and two second terminals 211, which can serve as the signal acquisition terminal and reference terminal in the body temperature detection circuit, respectively. This enables the acquisition and transmission of body temperature signals and forms a complete loop structure along the signal transmission path, reducing the influence of external electromagnetic interference and thus improving the anti-interference performance and stability of body temperature detection.
