Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to a connector and a continuous blood glucose monitoring device. Background Technology

[0002] CGM (Continuous Glucose Monitoring) is a technology that uses a glucose sensor to continuously monitor the glucose concentration in the subcutaneous interstitial fluid, thereby indirectly reflecting blood glucose levels. CGM products require a needle that punctures the skin using a sensor and auxiliary sensor pins. The sensor's enzymes react with the subcutaneous fluid in an electrochemical reaction, converting the signal into an electrical signal, which is then used to provide the user with a blood glucose value.

[0003] Currently, continuous glucose monitoring devices typically include a transmitter, a sensor, and a connector located on the transmitter. The connector has a receiving slot for accommodating the sensor and conductive plates for electrically connecting the sensor and the transmitter. During sensor assembly, the conductive end of the sensor needs to be installed in the receiving slot so that the conductive contacts of the sensor's conductive end contact the conductive plates, thus achieving electrical connection between the sensor and the transmitter via the connector. Simultaneously, the walls of the receiving slot can be used to clamp and fix the sensor, increasing its stability. However, due to the small size of continuous glucose monitoring devices, the connector's size is reduced, resulting in thinner walls. Consequently, when the sensor is installed in the connector's receiving slot, the walls on opposite sides of the receiving slot may move away from each other under the sensor's influence. This affects both the connector's clamping stability and the conductive stability between the sensor and the conductive plates. Utility Model Content

[0004] This application provides a connector to increase the clamping stability of the connector on the sensor and to increase the conductivity stability between the sensor and the conductive sheet.

[0005] The technical solution adopted in this application is as follows: A connector for electrically connecting a sensor to a transmitter, comprising: The base includes a first support part, a second support part, a connecting part, and a reinforcing structure for connecting the first support part and the second support part. The two sides of the connecting part are respectively fixedly connected to the first support part and the second support part, and the first support part, the second support part, and the connecting part together form a receiving groove for accommodating the sensor. A conductive sheet is disposed on the first support portion and at least partially protrudes from the groove wall of the receiving groove, so that the conductive sheet can abut against the conductive contact of the sensor.

[0006] By adopting the above technical solution, when assembling the sensor, first align the conductive end of the sensor with the receiving groove, and then apply pressure to the sensor in the direction of the connector so that the conductive end of the sensor moves into the receiving groove, and at the same time, the conductive contact of the conductive end of the sensor abuts against the conductive sheet to complete the assembly of the sensor.

[0007] Since the reinforcing structure is used to connect the first support and the second support, the connection stability of the first support and the second support can be increased by the reinforcing structure, thereby reducing the amount of movement of the first support and the second support in opposite directions when assembling the sensor. This increases the clamping stability of the connector on the sensor, thereby increasing the connection stability between the sensor and the connector. It also increases the conductivity stability between the sensor and the conductive sheet, thereby ensuring the working stability of the continuous blood glucose monitoring device with the connector of this application installed. Furthermore, the reinforcing structure can also increase the structural strength of the base, thereby further reducing the deformation of the base when installing the sensor, which further increases the clamping stability of the connector on the sensor and further increases the conductivity stability between the sensor and the conductive sheet.

[0008] Optionally, the reinforcing structure includes a reinforcing portion located at one end of the receiving groove, and the two ends of the reinforcing portion are respectively fixedly connected to the first supporting portion and the second supporting portion.

[0009] By adopting the above technical solution, since the two ends of the reinforcing part are fixedly connected to the first support part and the second support part respectively, when installing the sensor, the reinforcing part can be used to apply a pulling force in the direction of mutual approach to the first support part and the second support part, thereby reducing the amount of movement of the first support part and the second support part, thereby increasing the stability of the connector clamping the sensor and ensuring the conductivity stability of the conductive sheet and the sensor. Furthermore, since the reinforcing part is located at one end of the receiving groove, when installing the sensor, the reinforcing part can also be used to position the sensor, thereby reducing the difficulty of installing the sensor and achieving the effect of facilitating the precise installation of the sensor, and further ensuring the conductivity stability of the conductive sheet and the sensor.

[0010] Optionally, one side of the bottom of the reinforcing part is fixedly connected to the connecting part.

[0011] By adopting the above technical solution, when the first support and the second support move in opposite directions, the connecting part will deform toward the receiving groove. However, by fixing one side of the bottom of the reinforcing part to the connecting part, the bottom of the reinforcing part can be used to support the connecting part, so as to avoid the connecting part deforming toward the receiving groove. This reduces the amount of movement of the first support and the second support in opposite directions when assembling the sensor, thereby further increasing the clamping stability of the connector on the sensor and further increasing the conductivity stability between the conductive sheet and the sensor, and further increasing the working stability of the continuous blood glucose monitoring device with the connector of this application installed.

[0012] Optionally, the reinforcing structure includes a reinforcing rib located at the bottom of the base, with both ends of the reinforcing rib fixedly connected to the first support portion and the second support portion, respectively.

[0013] By adopting the above technical solution, when the sensor is installed, the tops of the first support and the second support will move away from each other under the action of the sensor, while the bottoms will move closer to each other. By setting the reinforcing rib at the bottom of the base and fixing both ends of the reinforcing rib to the first support and the second support respectively, the bottoms of the first support and the second support can be supported by the reinforcing rib, so as to keep the distance between the bottoms of the first support and the second support as constant as possible. This reduces the amount of movement of the tops of the first support and the second support in the away direction, thus keeping the distance between the tops of the first support and the second support as constant as possible. This increases the clamping stability of the connector on the sensor and the conductivity stability between the conductive sheet and the sensor, thereby ensuring the working stability of the continuous blood glucose monitoring device with the connector of this application installed. At the same time, by setting a groove structure to accommodate the reinforcing rib on the circuit board of the transmitter, the positioning and limiting of the connector can be achieved by the cooperation of the reinforcing rib and the groove structure, thereby increasing the connection stability between the connector and the transmitter.

[0014] Optionally, the base has a length direction, and multiple reinforcing ribs are spaced apart along the length direction.

[0015] By adopting the above technical solution, since multiple reinforcing ribs are spaced apart along the length of the base, the number of support points for the first and second support parts is increased. This further increases the difficulty for the bottoms of the first and second support parts to move towards each other, and thus further increases the difficulty for the tops of the first and second support parts to move away from each other. This further increases the clamping stability of the connector on the sensor and the conductive stability between the conductive sheet and the sensor, thereby further ensuring the working stability of the continuous blood glucose monitoring device equipped with the connector of this application.

[0016] Optionally, the bottom of the base has a positioning post with a length L and the reinforcing rib has a height H, where L and H satisfy: L > H.

[0017] By adopting the above technical solution, since the bottom of the base has a positioning post, a hole structure for accommodating the positioning post can be set on the transmitter's circuit board. The positioning post and the hole structure cooperate to achieve the positioning and limiting of the connector, thereby increasing the connection stability between the connector and the transmitter. Furthermore, since the length of the positioning post is greater than the height of the reinforcing rib, when assembling the connector on the transmitter's circuit board, the positioning post can first contact the transmitter's circuit board, allowing the positioning post to be inserted into the hole structure on the transmitter's circuit board. This allows the connector to be guided by the cooperation between the positioning post and the hole structure on the transmitter's circuit board, reducing the assembly difficulty of the connector and improving the assembly efficiency of the connector, thereby reducing the assembly cost of the continuous blood glucose monitoring device equipped with the connector of this application.

[0018] Optionally, the positioning post includes a positioning section and a guide section located on the side of the positioning section away from the base body. The diameter of the guide section gradually decreases in the direction away from the positioning section, and the length of the positioning section is greater than the height of the reinforcing rib.

[0019] By adopting the above technical solution, since the diameter of the guide section gradually decreases in the direction away from the positioning section, and the conductive section is located on the side of the positioning section away from the seat, the diameter of the end of the guide section away from the positioning section is smaller than the aperture of the hole structure on the circuit board of the transmitter. This reduces the difficulty of inserting the positioning post into the hole structure on the circuit board of the transmitter during the installation of the connector, thereby further reducing the assembly difficulty of the connector and further improving the assembly efficiency of the connector. In turn, it further reduces the assembly cost of the continuous blood glucose monitoring device with the connector of this application installed.

[0020] Optionally, the first support portion is provided with a first extension portion on the side opposite to the second support portion, and the bottom of the first extension portion is flush with the bottom of the first support portion. And / or, the second support portion is provided with a second extension portion on the side opposite to the first support portion, and the bottom of the second extension portion is flush with the bottom of the second support portion.

[0021] By adopting the above technical solution, since the first support part is provided with a first extension part on the side away from the second support part, and the bottom of the first extension part is flush with the bottom of the first support part, after the connector is installed on the circuit board of the transmitter, the bottoms of both the first support part and the first extension part can abut against the circuit board of the transmitter. This allows the first extension part to support the first support part, thereby increasing the stability of the first support part and reducing the amount of movement of the first support part away from the second support part when assembling the sensor. This further increases the clamping stability of the connector on the sensor and the conductive stability between the conductive sheet and the sensor.

[0022] Since the second support has a second extension on the side opposite to the first support, and the bottom of the second extension is flush with the bottom of the second support, after the connector is installed on the transmitter's circuit board, the bottoms of both the second support and the second extension can abut against the transmitter's circuit board. This allows the second extension to support the second support, thereby increasing the stability of the second support and reducing the amount of movement of the second support away from the first support when assembling the sensor. This further increases the clamping stability of the connector on the sensor and the conductive stability between the conductive sheet and the sensor.

[0023] Optionally, a limiting part is provided on the side of the second support part away from the first support part, and the limiting part is provided with a limiting hole.

[0024] By adopting the above technical solution, since a limiting part is provided on the side of the second support part away from the first support part, and the limiting part is provided with a limiting hole, a limiting post can be provided in the housing of the continuous blood glucose monitoring device. The insertion and cooperation of the limiting post and the limiting hole can further position and limit the connector, thereby further increasing the stability of the connector, and thus further increasing the stability of the connector in electrically connecting the transmitter and the sensor together, while indirectly increasing the stability of the sensor. In addition, after the connector is assembled with the circuit board of the transmitter, the bottom of the limiting part can also abut against the circuit board of the transmitter, so as to support the second support part with the limiting part, thereby further increasing the stability of the second support part, further reducing the amount of movement of the second support part away from the first support part when assembling the sensor, and further increasing the clamping stability of the connector on the sensor and further increasing the conductivity stability between the conductive sheet and the sensor.

[0025] This application also provides a continuous glucose monitoring device to increase the stability of the sensor and the stability of the electrical connection between the sensor and the transmitter.

[0026] A continuous glucose monitoring device includes a sensor, a transmitter, and a connector as described above. The transmitter has a circuit board, the connector is disposed on the circuit board, a conductive sheet is fixedly connected to the circuit board, at least a portion of the sensor is located in the receiving groove, and the conductive contacts of the sensor are in contact with the conductive sheet.

[0027] By adopting the above technical solution, since the continuous blood glucose monitoring device in this application uses the aforementioned connector, the amount of movement of the first support and the second support in opposite directions during sensor assembly is reduced, thereby increasing the clamping stability of the connector on the sensor and increasing the conductive stability between the sensor and the conductive sheet, thus increasing the stability of the sensor and the electrical connection stability between the sensor and the transmitter, and further increasing the working stability of the continuous blood glucose monitoring device.

[0028] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The connector in this application is used to electrically connect a sensor and a transmitter. It includes a base and a conductive plate. The base includes a first support portion, a second support portion, a connecting portion, and a reinforcing structure for connecting the first and second support portions. The two sides of the connecting portion are fixedly connected to the first and second support portions, respectively. The first, second, and connecting portions together form a receiving groove for accommodating the sensor. The conductive plate is disposed on the first support portion and at least partially protrudes from the groove wall of the receiving groove, so that the conductive plate can abut against the conductive contacts of the sensor. The reinforcing structure can then be used to increase the connection stability of the first and second support portions, thereby reducing... The reduced movement of the first and second support parts in opposite directions during sensor assembly increases the clamping stability of the connector on the sensor, thereby improving the connection stability between the sensor and the connector. It also increases the conductivity stability between the sensor and the conductive sheet, ensuring the operational stability of the continuous blood glucose monitoring device equipped with the connector of this application. Furthermore, the reinforced structure increases the structural strength of the base, further reducing the deformation of the base during sensor installation, which in turn further increases the clamping stability of the connector on the sensor and the conductivity stability between the sensor and the conductive sheet.

[0029] 2. The reinforcing structure in this application includes a reinforcing part, the two ends of which are fixedly connected to the first support part and the second support part, respectively. When installing the sensor, the reinforcing part can apply a pulling force in a mutually closer direction to the first support part and the second support part, thereby reducing the amount of movement of the first support part and the second support part, thus increasing the stability of the connector clamping the sensor and ensuring the conductivity stability of the conductive sheet and the sensor. The reinforcing part is located at one end of the receiving groove, and when installing the sensor, the reinforcing part can also be used to position the sensor, thereby reducing the difficulty of installing the sensor and facilitating the precise installation of the sensor, further ensuring the conductivity stability of the conductive sheet and the sensor.

[0030] 3. The reinforcing structure in this application includes a reinforcing rib located at the bottom of the base. The two ends of the reinforcing rib are fixedly connected to the first support part and the second support part, respectively. The reinforcing rib can support the bottom of both the first support part and the second support part, so as to keep the distance between the bottom of the first support part and the second support part as constant as possible. This reduces the amount of movement of the tops of the first support part and the second support part in opposite directions, thus keeping the distance between the tops of the first support part and the second support part as constant as possible. This increases the clamping stability of the connector on the sensor and the conductivity stability between the conductive sheet and the sensor, thereby ensuring the working stability of the continuous blood glucose monitoring device equipped with the connector in this application.

[0033] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0035] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0038] Reference Figures 1 to 6 A connector is disclosed for electrically connecting a sensor 8 to a transmitter. The connector includes a base and a conductive sheet 6. The base includes a first support portion 1, a second support portion 2, a connecting portion 3, and a reinforcing structure for connecting the first support portion 1 and the second support portion 2. The two sides of the connecting portion 3 are fixedly connected to the first support portion 1 and the second support portion 2, respectively. The first support portion 1, the second support portion 2, and the connecting portion 3 together form a receiving groove 11 for accommodating the sensor 8. The conductive sheet 6 is disposed on the first support portion 1 and at least partially protrudes from the groove wall of the receiving groove 11 so that the conductive sheet 6 can abut against the conductive contacts of the sensor 8.

[0039] It is understandable that the opposite sides of the first support part 1 and the second support part 2 respectively form the two opposite walls of the receiving groove 11, and the top end face of the connecting part 3 forms the bottom wall of the receiving groove 11.

[0040] When assembling the sensor 8, first align the conductive end of the sensor 8 with the receiving groove 11, and then apply pressure to the sensor 8 in the direction of the connector so that the conductive end of the sensor 8 moves into the receiving groove 11, and at the same time, the conductive contact of the conductive end of the sensor 8 abuts against the conductive sheet 6 to complete the assembly of the sensor 8.

[0041] Since the reinforcing structure is used to connect the first support 1 and the second support 2, the connection stability of the first support 1 and the second support 2 can be increased by the reinforcing structure, so as to reduce the amount of movement of the first support 1 and the second support 2 in opposite directions when assembling the sensor 8. This increases the clamping stability of the connector on the sensor 8, thereby increasing the connection stability between the sensor 8 and the connector. On the other hand, it increases the conductivity stability between the sensor 8 and the conductive sheet 6, so as to ensure the working stability of the continuous blood glucose monitoring device with the connector of this application installed. Furthermore, the reinforcing structure can also increase the structural strength of the base body, thereby reducing the deformation of the base body when installing the sensor 8, which further increases the clamping stability of the connector on the sensor 8 and further increases the conductivity stability between the sensor 8 and the conductive sheet 6.

[0042] This application does not specifically limit the structure of the first support part 1, the second support part 2, and the connecting part 3. Preferably, refer to Figures 1 to 6 The first support portion 1 and the second support portion 2 are both block structures, and the connecting portion 3 is a sheet structure located between the first support portion 1 and the second support portion 2. The first support portion 1, the second support portion 2, and the connecting portion 3 are integrally formed to reduce the manufacturing difficulty of the base and increase the connection stability between the connecting portion 3 and the first support portion 1 and the second support portion 2. In other embodiments, the first support portion 1, the second support portion 2, and the connecting portion 3 can all be other structures, as long as a receiving groove 11 is formed between the first support portion 1 and the second support portion 2, and both sides of the connecting portion 3 can be fixedly connected to the first support portion 1 and the second support portion 2 respectively.

[0043] This application does not specifically limit the structure of the conductive sheet 6; preferably, refer to... Figure 1 and Figure 3 The conductive sheet 6 includes a conductive segment 61 and an integrally formed connecting segment 62. The connecting segment 62 is fixedly connected to the first support portion 1. At least a portion of the connecting segment 62 is located on the side of the first support portion 1 opposite to the second support portion 2, and the portion of the connecting segment 62 on the side of the first support portion 1 opposite to the second support portion 2 is used for soldering to the circuit board of the sensor 8 to achieve electrical connection between the conductive sheet 6 and the circuit board of the sensor 8. The first support portion 1 is provided with a relief groove for accommodating the conductive segment 61. Both ends of the conductive segment 61 are located in the relief groove, and the middle position of the conductive segment 61 in the length direction protrudes towards the direction of the second support portion 2 and is located in the receiving groove 11, so that the portion of the conductive segment 61 located in the receiving groove 11 can guide the sensor 8 to facilitate the assembly of the sensor 8 into the connector. In other embodiments, the conductive sheet 6 can also have other structures, as long as it can be used to electrically connect the conductive contacts of the sensor 8 to the circuit board of the transmitter.

[0044] This application does not impose specific limitations on the strengthening structure, which can adopt any of the following embodiments: Implementation Method 1, in this implementation method, refer to Figure 1 The reinforcing structure includes a reinforcing part 4, which is located at one end of the receiving groove 11, and the two ends of the reinforcing part 4 are respectively fixedly connected to the first support part 1 and the second support part 2.

[0045] Since the two ends of the reinforcing part 4 are fixedly connected to the first support part 1 and the second support part 2 respectively, when the sensor 8 is installed, the reinforcing part 4 can apply a pulling force in the direction of mutual approach to the first support part 1 and the second support part 2, thereby reducing the amount of movement of the first support part 1 and the second support part 2, thereby increasing the stability of the connector clamping the sensor 8, so as to ensure the conductivity stability of the conductive sheet 6 and the sensor 8.

[0046] Furthermore, since the reinforcing part 4 is located at one end of the receiving groove 11, the reinforcing part 4 can be used to position the sensor 8 during installation, thereby reducing the difficulty of installing the sensor 8 and facilitating the precise installation of the sensor 8, thus further ensuring the conductivity stability of the conductive sheet 6 and the sensor 8.

[0047] This application does not specifically limit the structure of the reinforcing part 4. Preferably, the reinforcing part 4 is a block-shaped structure located in the receiving groove 11 to increase the connection stability between the reinforcing part 4 and the first support part 1 and the second support part 2, thereby further increasing the clamping stability of the connector on the sensor 8 and further increasing the conductivity stability between the conductive sheet 6 and the sensor 8. In other embodiments, the reinforcing part 4 may also be a sheet-like structure located at the ends of the first support part 1 and the second support part 2, or other structures capable of connecting the first support part 1 and the second support part 2.

[0048] This application does not specify the method of fixing the reinforcing part 4 to the first support part 1 and the second support part 2. Preferably, the reinforcing part 4 is integrally formed with the first support part 1 and the second support part 2. This increases the connection stability between the reinforcing part 4 and the first support part 1 and the second support part 2, and reduces the number of parts required for assembly during connector production, thereby improving connector production efficiency and reducing assembly costs. In other embodiments, the reinforcing part 4 can also be fixedly connected to the first support part 1 and the second support part 2 by means of adhesive bonding or other methods.

[0049] This application does not specifically limit the relationship between the reinforcing part 4 and the connecting part 3. Preferably, refer to... Figure 1 The bottom side of the reinforcing part 4 is fixedly connected to the connecting part 3.

[0050] When the first support 1 and the second support 2 move toward each other, the connecting part 3 will deform toward the receiving groove 11. By fixing one side of the bottom of the reinforcing part 4 to the connecting part 3, the bottom of the reinforcing part 4 can be used to support the connecting part 3, so as to avoid the connecting part 3 deforming toward the receiving groove 11. This reduces the amount of movement of the first support 1 and the second support 2 toward each other when assembling the sensor 8, thereby further increasing the clamping stability of the connector on the sensor 8 and further increasing the conductivity stability between the conductive sheet 6 and the sensor 8, and further increasing the working stability of the continuous blood glucose monitoring device equipped with the connector of this application.

[0051] Preferably, the reinforcing part 4 and the connecting part 3 are integrally formed to increase the connection stability between the reinforcing part 4 and the connecting part 3. The top of the reinforcing part 4 is flush with the top of the second support part 2 to increase the connection area between the connecting part 3 and the first support part 1 and the second support part 2, thereby further increasing the clamping stability of the connector on the sensor 8 and further increasing the conductivity stability between the conductive sheet 6 and the sensor 8, thereby further increasing the working stability of the continuous blood glucose monitoring device equipped with the connector of this application.

[0052] In other embodiments, the bottom side of the reinforcing part 4 may have a gap with the connecting part 3 or the two may simply be in contact.

[0053] Implementation Method Two: In this implementation method, refer to... Figures 2 to 4 The reinforcing structure includes a reinforcing rib 5 located at the bottom of the base, with both ends of the reinforcing rib 5 fixedly connected to the first support part 1 and the second support part 2, respectively.

[0054] When the sensor 8 is installed, the tops of the first support part 1 and the second support part 2 will move away from each other under the action of the sensor 8, and the bottoms will move closer to each other. By setting the reinforcing rib 5 at the bottom of the base and fixing the two ends of the reinforcing rib 5 to the first support part 1 and the second support part 2 respectively, the bottoms of the first support part 1 and the second support part 2 can be supported by the reinforcing rib 5, so as to keep the distance between the bottoms of the first support part 1 and the second support part 2 as constant as possible. This reduces the amount of movement of the tops of the first support part 1 and the second support part 2 in the opposite direction, thus keeping the distance between the tops of the first support part 1 and the second support part 2 as constant as possible. This increases the clamping stability of the connector on the sensor 8 and the conductive stability between the conductive sheet 6 and the sensor 8, so as to ensure the working stability of the continuous blood glucose monitoring device with the connector of this application installed.

[0055] Meanwhile, by setting a groove-shaped structure to accommodate the reinforcing rib 5 on the transmitter's circuit board, the positioning and limiting of the connector can be achieved by utilizing the cooperation between the reinforcing rib 5 and the groove-shaped structure, thereby increasing the connection stability between the connector and the transmitter.

[0056] This application does not specify the method of fixing the reinforcing rib 5 to the first support portion 1 and the second support portion 2. Preferably, the reinforcing rib 5 is integrally formed with the first support portion 1 and the second support portion 2 to increase the connection stability between the reinforcing rib 5 and the first support portion 1 and the second support portion 2. At the same time, it reduces the number of parts required for assembly during connector production, thereby improving the assembly efficiency of the connector and reducing the assembly cost of the connector. In other embodiments, the reinforcing rib 5 can also be connected to the first support portion 1 and the second support portion 2 by adhesive or other fixing methods.

[0057] This application does not specifically limit the relationship between the reinforcing rib 5 and the connecting portion 3. Preferably, the reinforcing rib 5 is integrally formed into the connecting portion 3 to further increase the stability of the reinforcing rib 5, thereby increasing the supporting effect of the reinforcing rib 5 on the first supporting portion 1 and the second supporting portion 2, and further increasing the clamping stability of the connector on the sensor 8 and the conductive stability between the conductive sheet 6 and the sensor 8. In other embodiments, there may be a gap between the reinforcing rib 5 and the connecting portion 3, or they may simply be in contact.

[0058] This application does not specify the number of reinforcing ribs 5; preferably, refer to... Figure 2 The base has a length direction, and multiple reinforcing ribs 5 are spaced apart along the length direction, thereby increasing the number of support points of the reinforcing ribs 5 for the first support part 1 and the second support part 2. This further increases the difficulty of the bottoms of the first support part 1 and the second support part 2 moving towards each other, and thus further increases the difficulty of the tops of the first support part 1 and the second support part 2 moving towards each other. This further increases the clamping stability of the connector on the sensor 8 and the conductivity stability between the conductive sheet 6 and the sensor 8, thereby further ensuring the working stability of the continuous blood glucose monitoring device equipped with the connector of this application.

[0059] Preferably, there are two reinforcing ribs 5 spaced apart, so as to reduce the manufacturing difficulty of the base body while ensuring the support points of the first support part 1 and the second support part 2.

[0060] In other embodiments, the reinforcing rib 5 may be provided as one or in other quantities.

[0061] Furthermore, refer to Figure 3 and Figure 4 The bottom of the base has a positioning post 7 with a length L and a reinforcing rib 5 with a height H. L and H satisfy: L > H.

[0062] It is understandable that the length direction of the positioning post 7 is set parallel to the height direction of the base body, and the length direction of the positioning post 7 is set parallel to the height direction of the reinforcing rib 5.

[0063] Because the base has a positioning post 7 at the bottom, the positioning post 7 can be positioned and limited by setting a hole structure on the transmitter circuit board to accommodate the positioning post 7, thereby increasing the connection stability between the connector and the transmitter.

[0064] Furthermore, since the length of the positioning post 7 is greater than the height of the reinforcing rib 5, when assembling the connector onto the transmitter's circuit board, the positioning post 7 can first contact the transmitter's circuit board, allowing it to be inserted into the hole structure on the transmitter's circuit board. This allows the positioning post 7 to guide the connector by cooperating with the hole structure on the transmitter's circuit board, reducing the difficulty of assembling the connector and improving the assembly efficiency, thereby reducing the assembly cost of the continuous blood glucose monitoring device equipped with the connector of this application.

[0065] This application does not specifically limit the location of the positioning post 7. Preferably, the positioning post 7 is located at the bottom of the first support part 1 to improve the positioning and limiting effect of the first support part 1, thereby ensuring the stability of the conductive sheet 6 as much as possible.

[0066] This application does not specifically limit the connection method between the positioning post 7 and the first support part 1. Preferably, the positioning post 7 is integrally formed into the first support part 1 to increase the connection stability between the positioning post 7 and the first support part 1, thereby ensuring the positioning and limiting effect of the positioning post 7 on the first support part 1. At the same time, it can also reduce the number of parts required for assembly during connector production, thereby improving connector production efficiency and reducing connector assembly costs. In other embodiments, the positioning post 7 can also be connected to the first support part 1 by adhesive bonding or plug-in connection.

[0067] In other embodiments, the positioning post 7 may also be located at the bottom of the second support portion 2 or the bottom of the connecting portion 3.

[0068] This application does not specifically limit the structure of the positioning column 7; preferably, refer to... Figures 2 to 4 The positioning column 7 includes a positioning section 71 and a guide section 72 located on the side of the positioning section 71 away from the seat. The diameter of the guide section 72 is gradually reduced in the direction away from the positioning section 71, and the length of the positioning section 71 is greater than the height of the reinforcing rib 5.

[0069] It is understandable that the end of the positioning segment 71 away from the guide segment 72 is connected to the base, the diameter of the positioning segment 71 remains unchanged in the direction away from the base, the diameter of the guide segment 72 near the base is equal to the diameter of the positioning segment 71, and the diameter of the hole structure on the circuit board of the transmitter is equal to the diameter of the positioning segment 71.

[0070] Since the diameter of the guide section 72 gradually decreases in the direction away from the positioning section 71, and the conductive section 61 is located on the side of the positioning section 71 away from the seat, the diameter of the end of the guide section 72 away from the positioning section 71 is smaller than the aperture of the hole structure on the transmitter's circuit board. This reduces the difficulty of inserting the positioning post 7 into the hole structure on the transmitter's circuit board during connector installation, thereby further reducing the difficulty of connector assembly and improving connector assembly efficiency. This further reduces the assembly cost of the continuous blood glucose monitoring device with the connector of this application.

[0071] In other implementation examples, the positioning post 7 can also be a structure with a cross-sectional shape such as a cone, an isosceles trapezoid, or a rectangle.

[0072] This application does not specify a particular number of positioning posts 7; preferably, refer to... Figure 2 Two positioning posts 7 are spaced apart along the length of the base body to enhance the guiding and positioning effect of the base body. This further facilitates the assembly of the connector and enhances the positioning and limiting effect of the connector, thereby increasing its stability. Both positioning posts 7 are located between two reinforcing ribs 5 to increase the distance between the two reinforcing ribs 5, thus ensuring the supporting effect of the reinforcing ribs 5 on the first support part 1 and the second support part 2. In other embodiments, one or other numbers of positioning posts 7 may be provided.

[0073] Implementation Method 3: In this implementation method, refer to... Figure 5 and Figure 6 The reinforcing structure includes a reinforcing part 4 and a reinforcing rib 5. The reinforcing part 4 is located at the ends of the first support part 1 and the second support part 2, and the two ends of the reinforcing part 4 are respectively fixedly connected to the first support part 1 and the second support part 2. The reinforcing rib 5 is located at the bottom of the seat, and the two ends of the reinforcing rib 5 are respectively fixedly connected to the first support part 1 and the second support part 2.

[0074] This embodiment can be understood as a combination of the above-described Embodiment 1 and Embodiment 2.

[0075] Because this embodiment combines the above-described embodiments one and two, the stability of the first support part 1 and the second support part 2 is further increased, thereby further increasing the clamping stability of the connector on the sensor 8 and the conductive stability between the connector and the conductive sheet 6, and further ensuring the working stability of the continuous blood glucose monitoring device equipped with the connector of this application.

[0076] Of course, in other embodiments, the reinforcing structure may also adopt other structures; for example, the reinforcing structure includes a C-shaped rod, which is located at the ends of the first support part 1 and the second support part 2, and the two ends of the C-shaped rod are respectively inserted into the first support part 1 and the second support part 2.

[0077] In a preferred embodiment, the first support portion 1 is provided with a first extension portion on the side opposite to the second support portion 2, and the bottom of the first extension portion is flush with the bottom of the first support portion 1.

[0078] It should be noted that, for the solutions of the above-described embodiments two and three, where the transmitter circuit board is provided with a groove-shaped structure for accommodating the reinforcing rib 5, the bottom of the first extension is flush with the bottom of the first support portion 1; while for the solution of the above-described embodiment one, or for the solutions of the above-described embodiments two and three where the transmitter circuit board does not have a groove-shaped structure for accommodating the reinforcing rib 5, the bottom of the first extension is flush with the bottom of the reinforcing rib 5.

[0079] Since the first support part 1 has a first extension part on the side away from the second support part 2, and the bottom of the first extension part is flush with the bottom of the first support part 1, after the connector is installed on the circuit board of the transmitter, the bottoms of both the first support part 1 and the first extension part can abut against the circuit board of the transmitter. The first extension part can support the first support part 1, thereby increasing the stability of the first support part 1 and reducing the amount of movement of the first support part 1 away from the second support part 2 when assembling the sensor 8. This further increases the clamping stability of the connector on the sensor 8 and the conductivity stability between the conductive sheet 6 and the sensor 8.

[0080] This application does not specifically limit the structure of the first extension. Preferably, the first extension is a block-shaped structure formed by at least a portion of the first support portion 1 extending in a direction away from the second support portion 2, thereby increasing the connection stability between the first extension and the first support portion 1, ensuring the supporting effect of the first extension on the first support portion 1, and also reducing the number of components required to assemble the connector, thus improving the assembly efficiency and reducing the assembly cost. In other embodiments, the first extension may also be a structure of other shapes separately provided on the first support portion 1.

[0081] In a preferred embodiment, the second support portion 2 is provided with a second extension portion on the side opposite to the first support portion 1, and the bottom of the second extension portion is flush with the bottom of the second support portion 2.

[0082] It should be noted that, for the solutions of the above-described embodiments two and three, where the transmitter circuit board is provided with a groove-shaped structure for accommodating the reinforcing rib 5, the bottom of the second extension is flush with the bottom of the second support 2; while for the solution of the above-described embodiment one, or for the solutions of the above-described embodiments two and three where the transmitter circuit board does not have a groove-shaped structure for accommodating the reinforcing rib 5, the bottom of the second extension is flush with the bottom of the reinforcing rib 5.

[0083] Since the second support part 2 has a second extension on the side opposite to the first support part 1, and the bottom of the second extension is flush with the bottom of the second support part 2, after the connector is installed on the circuit board of the transmitter, the bottoms of both the second support part 2 and the second extension can abut against the circuit board of the transmitter. The second extension can support the second support part 2, thereby increasing the stability of the second support part 2 and reducing the amount of movement of the second support part 2 away from the first support part 1 when assembling the sensor 8. This further increases the clamping stability of the connector on the sensor 8 and the conductivity stability between the conductive sheet 6 and the sensor 8.

[0084] This application does not specifically limit the structure of the second extension. Preferably, the second extension is a block-shaped structure formed by at least a portion of the second support portion 2 extending in a direction away from the first support portion 1, thereby increasing the connection stability between the second extension and the second support portion 2, ensuring the supporting effect of the second extension on the second support portion 2, and also reducing the number of components required to assemble the connector, thus improving the assembly efficiency and reducing the assembly cost. In other embodiments, the second extension may also be a structure of other shapes separately provided on the second support portion 2.

[0085] In a preferred embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The second support part 2 is provided with a limiting part 21 on the side opposite to the first support part 1, and the limiting part 21 is provided with a limiting hole 211.

[0086] It is understandable that the limiting part 21 is fixedly connected to the side of the second support part 2 that is away from the first support part 1.

[0087] It should be noted that, for the solutions of Embodiment 2 and Embodiment 3 described above, where the transmitter circuit board is provided with a groove-shaped structure for accommodating the reinforcing rib 5, the bottom of the limiting part 21 is flush with the bottom of the second support part 2; while for the solution of Embodiment 1 described above, or for the solutions of Embodiment 2 and Embodiment 3 described above where the transmitter circuit board does not have a groove-shaped structure for accommodating the reinforcing rib 5, the bottom of the limiting part 21 is flush with the bottom of the reinforcing rib 5.

[0088] Since the second support part 2 is provided with a limiting part 21 on the side opposite to the first support part 1, and the limiting part 21 is provided with a limiting hole 211, a limiting post can be provided in the housing 9 of the continuous blood glucose monitoring device to further position and limit the connector by using the insertion and cooperation of the limiting post and the limiting hole 211, so as to further increase the stability of the connector, thereby further increasing the stability of the connector in electrically connecting the transmitter and the sensor 8 together, and indirectly increasing the stability of the sensor 8.

[0089] In addition, after the connector is assembled onto the transmitter's circuit board, the bottom of the limiting part 21 can be made to abut against the transmitter's circuit board, so that the limiting part 21 can support the second support part 2, thereby further increasing the stability of the second support part 2, further reducing the amount of movement of the second support part 2 away from the first support part 1 when assembling the sensor 8, and further increasing the clamping stability of the connector on the sensor 8 and further increasing the conductivity stability between the conductive sheet 6 and the sensor 8.

[0090] This application does not specifically limit the fixing connection method between the limiting part 21 and the second support part 2. Preferably, the limiting part 21 is integrally formed into the second support part 2 to increase the connection stability between the limiting part 21 and the second support part 2, thereby ensuring the stability of the connector. It also reduces the number of parts required for assembly during connector production, thus improving assembly efficiency and reducing assembly costs. In other embodiments, the limiting part 21 can also be connected to the second support part 2 using other fixing methods such as adhesive bonding.

[0091] This application does not specifically limit the structure of the limiting part 21. Preferably, the limiting part 21 is a block structure to increase the mating area between the limiting part 21 and the housing 9 of the continuous glucose monitoring device through the limiting hole 211, thereby further increasing the stability of the connector. In other embodiments, the limiting part 21 may also be a sheet or other shapes.

[0092] Of course, in other embodiments, the limiting part 21 can also be disposed at the ends of the first support part 1 and the second support part 2, and the limiting part 21 and the reinforcing part 4 can both be arranged at the same end of the first support part 1 and the second support part 2, so that the limiting part 21 can be used to position and support the first support part 1 and the second support part 2, thereby further increasing the clamping stability of the connector on the sensor 8 and further increasing the conductivity stability between the conductive sheet 6 and the sensor 8; or, the second extension part and the limiting part 21 can be integrated into a single structure to simplify the structural design of the connector and reduce the manufacturing cost of the connector.

[0093] Reference Figure 7 This application also discloses a continuous glucose monitoring device, which includes a sensor 8, a transmitter, and a connector as described above. Figure 7 (Not shown) It has a circuit board, a connector is disposed on the circuit board, a conductive sheet 6 is fixedly connected to the circuit board, at least a portion of the sensor 8 is located in the receiving groove 11, and the conductive contact of the sensor 8 is in contact with the conductive sheet 6.

[0094] It is understood that the continuous glucose monitoring device may also have a housing 9, with the transmitter, sensor 8 and connector all located inside the housing 9, and at least a portion of the sensor 8 extending outside the housing 9 to be able to penetrate subcutaneous tissue; the connecting segment 62 of the conductive sheet 6 is soldered and fixed to the circuit board, and the sensor 8 has a conductive end located in the receiving groove 11, and the conductive end is provided with a conductive contact that contacts the conductive segment 61 of the conductive sheet 6.

[0095] Because the continuous blood glucose monitoring device in this application uses the aforementioned connector, the amount of movement of the first support 1 and the second support 2 in opposite directions during the assembly of the sensor 8 is reduced. This increases the clamping stability of the connector on the sensor 8 and the conductive stability between the sensor 8 and the conductive sheet 6, thereby increasing the stability of the sensor 8 and the electrical connection stability between the sensor 8 and the transmitter, and further increasing the operational stability of the continuous blood glucose monitoring device.

[0096] Regarding the solutions of Embodiments 2 and 3 above, the circuit board is provided with a groove structure for accommodating the reinforcing rib 5 and a hole structure for accommodating the positioning post 7, so as to realize the positioning and limiting of the connector by utilizing the cooperation between the reinforcing rib 5 and the groove structure and the cooperation between the positioning post 7 and the hole structure, thereby increasing the connection stability between the connector and the circuit board.

[0097] Preferably, the housing 9 is provided with a limiting post extending into the limiting hole 211, so as to limit the connector by the cooperation of the limiting post and the limiting hole 211, thereby increasing the stability of the connector.
