CGM products test blood sugar by puncturing human skin with a puncture needle and sensor pins. The bio-enzyme on the sensor reacts with the subcutaneous interstitial fluid to produce an electrochemical reaction, which is converted into an electrical signal and then converted into a blood sugar value to provide to the user.
[0003] The online blood glucose monitoring device includes a transmitter, a connector provided on the transmitter, and a sensor. The connector is provided with a receiving groove, the sensor is plugged into the receiving groove, and the groove wall of the receiving groove is provided with a conductive part. The sensor is provided with an electrical contact in contact with the conductive part, so that the sensor is electrically connected with the transmitter through the connector. The conductive part is usually a convex point protruding from the groove wall of the receiving groove, which leads to a high hardness of the conductive part, and in order to ensure the connection stability between the sensor and the connector, the conductive part needs to be pressed against the electrical contact, which leads to a high pressure between the electrical contact of the sensor and the conductive part during the assembly of the sensor, so there is a risk of damage to the electrical contact, which in turn affects the product quality and production cost of the online blood glucose monitoring device. Utility Model Content
[0004] The present application provides a connector and an online blood glucose monitoring device to ensure the product quality of the online blood glucose monitoring device and reduce the production cost.
[0005] The technical solution adopted in this application is:
[0006] A plug connector, used to electrically connect a sensor to a transmitter, comprises a body and an elastic conductive sheet, the body being provided with a plug slot and a mounting slot interconnected with the plug slot, the elastic conductive sheet being arranged in the mounting slot and having a contact section extending into the plug slot and contacting with the sensor, the contact section being able to move relative to the slot wall of the plug slot so that the contact section elastically avoids the sensor when the sensor is inserted into the plug slot.
[0007] By adopting the above technical solution, when assembling the sensor, first align the sensor with the notch of the plug-in slot, and then apply a force toward the plug-in slot to the sensor so that the sensor enters the plug-in slot. When the sensor contacts the contact section, the sensor applies an extrusion force toward one side of the plug-in slot to the contact section, and then the contact section moves toward the side away from the sensor, so that the contact section and the sensor elastically give way to each other, thereby reducing the pressure between the contact section and the sensor, thereby reducing the pressure between the contact section and the sensor, and further reducing the risk of possible damage to the sensor, so as to improve the product quality of the online blood glucose monitoring device equipped with the connector, and at the same time avoid the need to replace the sensor during the assembly process, thereby reducing the production cost of the online blood glucose monitoring device equipped with the connector.
[0008] In addition, after the sensor is installed in the plug slot, the elastic conductive sheet is pressed against the sensor under the action of its own elastic force to ensure the connection stability between the sensor and the plug connector, thereby ensuring the electrical connection effect between the sensor and the transmitter. In addition, the presence of the elastic conductive sheet enables the plug connector to be adapted to sensors of various thicknesses, so as to improve and optimize the online blood glucose monitoring device, thereby reducing the cost of improving and optimizing the online blood glucose monitoring device.
[0009] Optionally, the elastic conductive sheet further comprises a guide section, and the guide section is obliquely extended from the first end of the contact section in a direction close to the notch of the plug-in slot.
[0010] By adopting the above technical solution, when assembling the sensor, the sensor first contacts the guide section. Since the guide section is obliquely extended from the first end of the contact section in the direction close to the notch of the plug-in slot, the guide section can guide the sensor so that the sensor can enter the plug-in slot more smoothly and quickly, thereby improving the assembly efficiency of the sensor and reducing the assembly cost of the sensor; at the same time, the guide section can also guide the contact section to further increase the elastic avoidance effect between the contact section and the sensor, thereby further avoiding the risk of possible damage to the sensor and ensuring the electrical conduction effect between the sensor and the transmitter.

[0014] By adopting the above technical solution, the connecting section is extended from the second end of the contact section, and the first end is closer to the top surface of the body than the second end, so that the elastic conductive sheet is connected to the body at its bottom to ensure the elastic movement range of the contact section, thereby ensuring the elastic avoidance effect of the contact section and the sensor; at the same time, at least part of the welding section is exposed to the bottom of the body, so as to electrically connect the welding section and the transmitter together, thereby achieving the effect of facilitating electrical conduction between the plug-in and the transmitter. In addition, the connection between the welding section and the transmitter can also play the effect of fixing the plug-in to increase the connection stability between the plug-in and the transmitter.
[0015] Optionally, the contact segment is in contact with the sensor line;
[0016] Alternatively, the contact section is in contact with the sensor surface.
[0017] By adopting the above technical solution, after the sensor is installed on the connector, the contact section contacts the sensor line, thereby increasing the contact area between the sensor and the elastic conductive sheet, thereby increasing the electrical connection stability between the sensor and the elastic conductive sheet, to ensure the electrical conduction effect between the sensor and the transmitter, and further ensure the stability of the online blood glucose monitoring device installed with the connector during operation, thereby improving the user experience. At the same time, the pressure between the contact section and the sensor is reduced to further reduce the wear on the sensor, thereby further avoiding the risk of possible damage to the sensor.
[0018] After the sensor is installed on the connector, the contact section contacts the sensor surface, which further increases the contact area between the sensor and the elastic conductive sheet, thereby further increasing the electrical connection stability between the sensor and the elastic conductive sheet, further ensuring the electrical conduction effect between the sensor and the generator, and further ensuring the stability of the online blood glucose monitoring device installed with the connector. At the same time, the pressure between the contact section and the sensor is also reduced to further reduce the wear on the sensor, thereby further avoiding the risk of possible damage to the sensor.
[0019] Optionally, the contact segment is provided with a contact arc surface protruding toward the outside of the plug-in slot;

At the same time, when assembling the sensor, the contact arc surface can also guide the sensor and the contact segment to ensure the avoidance effect of the contact segment and the sensor, further avoiding the risk of possible damage to the sensor.

In addition, it can also reduce the difficulty of producing sensors that match the plug connector, so as to reduce the production cost of the online blood glucose monitoring device installed with the plug connector.

[0053] Reference Figures 1 to 5 A connector is used to electrically connect a sensor 3 with a transmitter, comprising a main body 1 and an elastic conductive sheet 2. The main body 1 is provided with a plug-in slot 11 and a mounting slot 12 interconnected with the plug-in slot 11. The elastic conductive sheet 2 is arranged in the mounting slot 12 and has a contact section 21 extending into the plug-in slot 11 and contacting the sensor 3. The contact section 21 can move relative to the slot wall of the plug-in slot 11 so that the contact section 21 elastically avoids the sensor 3 when the sensor 3 is inserted into the plug-in slot 11.
[0054] When assembling the sensor 3, first align the sensor 3 with the notch of the plug-in slot 11, and then apply a force to the sensor 3 in the direction of the plug-in slot 11 to make the sensor 3 enter the plug-in slot 11. When the sensor 3 contacts the contact section 21, the sensor 3 applies an extrusion force to the contact section 21 toward the side of the plug-in slot 11, and then the contact section 21 moves toward the side away from the sensor 3, so that the contact section 21 and the sensor 3 elastically give way to each other, so as to reduce the pressure between the contact section 21 and the sensor 3, thereby reducing the pressure between the contact section 21 and the sensor 3, and further reducing the risk of possible damage to the sensor 3, so as to improve the product quality of the online blood glucose monitoring device equipped with the connector, and at the same time avoid the need to replace the sensor 3 during the assembly process, thereby reducing the production cost of the online blood glucose monitoring device equipped with the connector.
[0055] In addition, after the sensor 3 is installed in the plug slot 11, the elastic conductive sheet 2 is pressed against the sensor 3 under the action of its own elastic force to ensure the connection stability between the sensor 3 and the plug connector, thereby ensuring the electrical connection effect between the sensor 3 and the transmitter. In addition, the presence of the elastic conductive sheet 2 enables the plug connector to be adapted to sensors 3 of various thicknesses, so as to improve and optimize the online blood glucose monitoring device, thereby reducing the cost of improving and optimizing the online blood glucose monitoring device.
[0056] The present application does not specifically limit the structure of the elastic conductive sheet 2. Preferably, refer to Figure 1, Figure 2 , Figure 4 and Figure 5 The elastic conductive sheet 2 also has a guide section 22 , which is obliquely extended from the first end of the contact section 21 along a direction close to the notch of the plug-in slot 11 .
[0057] That is to say, when assembling the sensor 3, the sensor 3 first contacts the guide section 22. Since the guide section 22 is obliquely extended from the first end of the contact section 21 in the direction close to the notch of the plug-in slot 11, the guide section 22 can guide the sensor 3 so that the sensor 3 can enter the plug-in slot 11 more smoothly and quickly, thereby improving the assembly efficiency of the sensor 3 and reducing the assembly cost of the sensor 3. At the same time, the guide section 22 can also guide the contact section 21 to further increase the elastic avoidance effect between the contact section 21 and the sensor 3, thereby further avoiding the risk of possible damage to the sensor 3 and ensuring the electrical conduction effect between the sensor 3 and the transmitter.
[0058] It should be noted that the notch of the plug-in slot 11 is the notch located on the top surface of the body 1 , and the first end of the contact segment 21 is the end of the contact segment 21 close to the notch of the plug-in slot 11 .
[0059] In a preferred embodiment, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 The main body 1 is also provided with an avoidance groove 13 which is recessed from the top of the main body 1 and communicates with the plug-in groove 11 , and the guide section 22 is at least partially disposed in the avoidance groove 13 .
[0060] Specifically, the end of the guide section 22 away from the contact section 21 is located in the avoidance groove 13, so that the guide section 22 and the notch of the plug-in slot 11 are avoided, thereby ensuring the width of the notch of the plug-in slot 11, so as to further achieve the effect of facilitating the installation of the sensor 3 in the plug-in slot 11; at the same time, the avoidance space between the guide section 22 and the sensor 3 can be increased to avoid the situation that the sensor 3 may be stuck with the guide section 22 when the sensor 3 is installed, so as to further improve the assembly efficiency of the sensor 3. At the same time, because the guide section 22 is located on the side of the contact section 21 close to the notch of the plug-in slot 11, the setting of the avoidance groove 13 can also remind the assembler that the contact section 21 is located at the position of the plug-in slot 11, so as to greatly improve the assembly efficiency of the assembler for the sensor 3. In addition, when the contact section 21 is deformed, the guide section 22 contacts the groove wall of the avoidance groove 13, so that the groove wall of the avoidance groove 13 applies a reverse force to the guide section 22, thereby increasing the ability of the elastic conductive sheet 2 to recover the deformation, so as to ensure that the contact section 21 and the sensor 3 are in a tight state, increase the connection stability between the sensor 3 and the connector, and increase the electrical conduction effect between the sensor 3 and the transmitter.
[0061] It should be noted that the formation method of the avoidance groove 13 is not limited to the above-mentioned formation method. In other embodiments, the avoidance groove 13 can also be formed by the groove wall of the plug-in groove 11 being recessed toward the outside of the body 1 .
[0062] In a preferred embodiment, referring to Figure 2 The elastic conductive sheet 2 also has a connecting section 23 extending from the second end of the contact section 21 and a welding section 24 extending from the connecting section 23. The connecting section 23 is connected to the body 1 to fix the elastic conductive sheet 2 to the body 1. The welding section 24 is at least partially exposed to the bottom of the body 1. The first end and the second end are arranged opposite to each other and the first end is closer to the top surface of the body 1 than the second end.
[0063] The connecting section 23 is extended from the second end of the contact section 21, so that the elastic conductive sheet 2 is connected to the body 1 at its bottom to ensure the elastic movement range of the contact section 21, thereby ensuring the elastic avoidance effect of the contact section 21 and the sensor 3; at the same time, at least part of the welding section 24 is exposed to the bottom of the body 1, so as to electrically connect the welding section 24 with the circuit board of the transmitter, thereby achieving the effect of facilitating the electrical connection between the plug-in component and the transmitter. In addition, the connection between the welding section 24 and the transmitter can also play the effect of fixing the plug-in component to increase the connection stability between the plug-in component and the transmitter.
[0064] It should be noted that the end of the contact section 21 away from the notch of the plug-in slot 11 is the second end; the first end is closer to the top surface of the body 1 than the second end, that is, the distance from the first end to the top surface of the body 1 is smaller than the distance from the second end to the top surface of the body 2.
[0065] Better, refer to Figure 4 and Figure 5 A notch 14 is provided at the bottom of the main body 1 corresponding to the welding section 24, and the portion of the welding section 24 located at the notch 14 is bent and extended toward the outside of the main body 1, so that at least part of the welding section 24 extends to the outside of the main body 1, and at the same time, the bottom of the welding section 24 is flush with the bottom of the main body 1 to ensure that the main body 1 can contact the circuit board of the transmitter, thereby increasing the connection stability between the connector and the circuit board; in addition, the connection difficulty between the welding section 24 and the circuit board of the transmitter is reduced, thereby further achieving the effect of facilitating the connection of the welding section 24 with the circuit board of the transmitter.
[0066] In a preferred embodiment, the connecting section 23 has a first section extending upward from the bottom of the contact section 21 and a second section extending downward from the first section, and the first section and the second section together form a "V"-shaped or "U"-shaped structure opening downward to further increase the elastic deformation range of the contact section 21, thereby ensuring the elastic avoidance effect between the contact section 21 and the sensor 3.
[0067] The present application does not specifically limit the connection method between the connecting section 23 and the body 1. Preferably, refer to Figure 3 and Figure 5 , the second section is provided with extension pieces 231 extending from opposite sides, the groove wall of the installation groove 12 is provided with a connecting groove 121 corresponding to the extension piece 231, and the extension piece 231 is plugged and matched with the connecting groove 121 to realize the fixed connection between the connecting section 23 and the body 1. In other embodiments, the connecting section 23 can also be fixedly connected to the body 1 by other methods such as hot melting, fastener fixing, etc.
[0068] The present application does not specifically limit the assembly method of the connecting section 23 and the body 1, and any one of the following embodiments may be adopted:
[0069] Embodiment 1, in this embodiment, refer to Figure 2 The notch of the mounting groove 12 and the notch of the plug-in groove 11 are arranged to be opposite to each other, that is, the notch of the plug-in groove 11 is located on the top surface of the body 1, and the notch of the mounting groove 12 is located on the bottom surface of the body 1, so that the connecting section 23 is installed in the mounting groove 12 from top to bottom, so that the notch of the mounting groove 12 and the notch of the avoidance groove 13 form an avoidance, so as to achieve the effect of preventing the connecting section 23 from being installed misplaced.
[0070] Example 2, in this embodiment, refer to Figure 5 The notch of the mounting groove 12 and the notch of the plug-in groove 11 are located on the same end surface of the main body 1, that is, the notch of the plug-in groove 11 and the notch of the mounting groove 12 are both located on the top surface of the main body 1, so that the connecting section 23 is installed in the mounting groove 12 from top to bottom, so that after the welding section 24 is connected to the circuit board of the transmitter, it can apply pressure to the main body 1 in the direction of the circuit board, so as to increase the stability of the main body 1 and avoid relative shaking between the main body 1 and the circuit board.
[0071] In other embodiments, the guide section 22 may be omitted, and the contact section 21 may be bent in a direction away from the notch of the plug slot 11 , so that the contact section 21 itself can guide the sensor 3 .
[0072] The present application does not specifically limit the contact method between the contact segment 21 and the sensor 3, and it can adopt any one of the following embodiments:
[0073] Embodiment 1: In this embodiment, the contact segment 21 is in line contact with the sensor 3, thereby increasing the contact area between the sensor 3 and the elastic conductive sheet 2, thereby increasing the electrical connection stability between the sensor 3 and the elastic conductive sheet 2, to ensure the electrical conduction effect between the sensor 3 and the transmitter, thereby ensuring the stability of the online blood glucose monitoring device equipped with the connector during operation, and improving the user experience. At the same time, the pressure between the contact segment 21 and the sensor 3 is reduced to further reduce the wear on the sensor 3, thereby further avoiding the risk of possible damage to the sensor 3.
[0074] In a preferred embodiment, referring to Figure 2 The contact segment 21 is provided with a contact arc surface 211 protruding toward the outside of the plug slot 11, so that the sensor 3 is in line contact with the contact segment 21, so as to ensure the electrical conduction effect between the sensor 3 and the elastic conductive sheet 2, and further ensure the electrical conduction effect between the sensor 3 and the transmitter. At the same time, the contact arc surface 211 can also guide the sensor 3, so as to further ensure the elastic avoidance effect between the contact segment 21 and the sensor 3, and further ensure the smoothness of the sensor 3 being installed in the plug slot 11.
[0075] The present application does not specifically limit the formation method of the contact arc surface 211. Preferably, refer to Figure 2 The contact segment 21 is arranged to be inclined toward the outside of the body 1 along the direction close to the notch of the plug slot 11, and the inclined direction is opposite to the inclined direction of the guide segment 22. At the same time, one end of the contact segment 21 close to the guide segment 22 is bent toward the direction where the guide segment 22 is located, so that the contact segment 21 forms a contact arc surface 211 at a position close to the guide segment 22, and the deformation range of the contact segment 21 is increased. In other implementation examples, the contact segment 21 is provided with a protrusion, and the side of the protrusion facing away from the contact segment 21 forms a contact arc surface 211.
