Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an electrical connection device and an analyte detection device. Background Technology

[0002] Traditional medical testing mostly involves obtaining samples by pricking fingers or drawing blood, and then testing them outside the body to obtain information on the content of analytes. This traditional method can only obtain limited data, and the sampling process is very unfriendly to the human body, causing significant harm. With technological advancements, current regulations allow the development of analyte detection devices that can continuously monitor human analyte levels over long periods. These devices include sensors that can acquire large amounts of data on the content of analytes in the human body over extended periods.

[0003] There are many analytes in the human body that need to be monitored. These bodily fluid analytes are valuable for long-term monitoring, such as glucose in bodily fluids. By frequently acquiring glucose data in the human body, we can understand in real time what measures need to be taken to increase / decrease blood sugar levels. This also includes comfort, convenience, pain associated with the monitored analytes, monitoring frequency, improving blood sugar control, and achieving efficient and accurate blood sugar management.

[0004] To obtain more monitoring data for analytes, the sensors of analyte detection devices need to be implanted in tissue fluid and worn on the body for extended periods. Therefore, electronic components are needed to provide the electrical signals required for the sensor to react with glucose in the tissue fluid, collect the generated electrical signals, and transmit them to the user so that the user can obtain the glucose level in the body. During the application and collection of electrical signals, electrical connection devices are needed to achieve a soft-hard connection between the sensor and the electronic components. Therefore, an electrical connection device with good electrical signal stability is required. Utility Model Content

[0051] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0052] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0053] This application provides an electrical connection device 1, such as... Figures 1 to 16 As shown, the electrical connection device 1 includes: at least one conductive element 100 and a mounting shell 200 covering the conductive element 100. The conductive element 100 includes a connecting piece 10, a welding piece 20, and a contact 30. One side of the connecting piece 10 is connected to the contact 30, and the other end of the connecting piece 10 is connected to the welding piece 20. The mounting shell 200 is provided with a communicating receiving groove 201 and a mounting groove 202. The connecting piece 10 and the welding piece 20 are placed in the mounting groove 202, and the contact 30 is placed in the receiving groove 201. The length direction of the contact 30 is consistent with the length direction of the receiving groove 201, and the contact 30 is used to abut against the sensor 2.

[0054] In this embodiment, as Figure 17 As shown, the welding piece 20 is used to weld together with electronic components (e.g., PCB board), and the contact piece 30 is used to contact the sensor 2. During assembly, the connecting piece 10 is fixed in the mounting groove 202 of the mounting housing 200, and the contact piece 30 is located in the receiving groove 201. Then, the sensor 2 is inserted into the receiving groove 201 and the contact piece 30 abuts against the sensor 2. Next, the mounting housing 200 is fixed on the electronic components, and the welding piece 20 is welded together with the electronic components.

[0055] In this embodiment, the contact 30 and the receiving groove 201 fix the sensor 2, preventing the sensor 2 from falling off during biological movement and preventing disconnection. This ensures stable and reliable contact between the sensor 2 and the contact 30, thereby guaranteeing a stable and effective connection between the sensor 2 and the electronic components in complex operating environments. Furthermore, the length direction of the contact 30 is aligned with the length direction of the receiving groove 201, increasing the proportion of the contact 30 within the receiving groove 201 and thus increasing the contact area between the contact 30 and the sensor 2. This prevents the contact 30 from damaging the sensor 2, avoiding abnormal or non-transmittable signal transmission and improving the stability of the electrical signal between the electronic components and the sensor 2. In addition, the mounting shell 200 covers the conductive component 100, ensuring the waterproof and dustproof protection of the connection circuit between the electronic components and the sensor 2. Moreover, the structure of this application is simple, consisting only of the mounting shell 200 and the conductive component 100, reducing the size of the electronic connection device.

[0056] In this embodiment, the connecting piece 10 and the mounting shell 200 can be connected by means of bonding, hot melt welding, or insert injection molding.

[0057] In this embodiment, the mounting shell 200 and the electronic components can be connected by means of bonding, welding or other methods.

[0058] In this embodiment, the contact element 30 can be a planar element, a curved element 60, or a structure formed by bending a surface into a cylindrical element.

[0059] In this embodiment, the welded part 20 can be a sheet or a sheet bent into an irregular shape.

The fastener 40 is spaced apart from the welding component 20 and the contact component 30, and the fastener 40 and the welding component 20 are respectively located at both ends of the connecting piece 10. The mounting shell 200 is provided with a slot 203 communicating with the mounting groove 202, and the fastener 40 is inserted into the slot 203.

[0061] In this embodiment, the fastener 40 is inserted into the slot 203 of the mounting shell 200 to connect the conductive component 100 to the mounting shell 200. This eliminates the need for methods such as bonding, hot-melt welding, or insert injection molding to fix the connector to the mounting shell 200, thus reducing assembly difficulty.

[0062] In this embodiment, the fastener 40 and the welded part 20 are located at the two ends of the connecting piece 10, so that when the fastener 40 is inserted into the slot 203, the mounting shell 200 will not block the welded part 20, so as to facilitate welding of the welded part 20.

[0063] Furthermore, the end of the fastener 40 away from the connecting piece 10 is provided with a bevel (not shown) to facilitate the insertion of the fastener 40 into the slot 203.

The mounting groove 202 and the receiving groove 201 are formed on the first end face 204. The first end face 204 is provided with a boss 206, which is located close to the receiving groove 201. The welded part 20 protrudes from the mounting groove 202, and the end of the welded part 20 away from the connecting piece 10 is flush with the end of the boss 206 away from the first end face 204.

[0065] In this embodiment, the welding component 20 protrudes from the mounting groove 202, so that when the mounting shell 200 is fixed on the electronic component, the welding component 20 can be exposed, so as to facilitate welding the welding component 20 to the electronic component. The end of the welding component 20 away from the connecting piece 10 is flush with the end of the boss 206 away from the first end face 204, which can prevent the welding component 20 from affecting the connection between the mounting shell 200 and the electronic component. In addition, the end of the boss 206 away from the first end face 204 is used to connect with the electronic component, which prevents the mounting shell 200 from accidentally touching the contact 30 when connecting with the electronic component, so that the contact between the sensor 2 and the contact 30 is stable and reliable.

[0066] Furthermore, the end of the contact member 30 away from the connecting piece 10 is flush with the end of the boss 206 away from the first end face 204.

[0067] In this embodiment, on the one hand, the contact 30 can be prevented from affecting the connection between the mounting shell 200 and the electronic components, and on the other hand, the area of ​​the contact 30 is increased, thereby increasing the contact area between the contact 30 and the sensor 2 and improving the stability of the electrical signal between the electronic components and the sensor 2.

[0072] Or, such as Figures 1 to 5 As shown, in Embodiment 1, the side of the second bent portion 52 away from the first bent portion 51 is located in the receiving groove 201.

[0073] In this embodiment, the irregular sheet 50 is formed by cutting or bending, and the first bending portion 51 and the second bending portion 52 form an L-shaped irregular sheet 50; wherein, the first bending portion 51 provides elastic force and deformation force to the contact member 30 to prevent the contact member 30 from deforming, so as to realize the controllable pressing force of the electrical connection device 1 on the sensor 2; the second bending portion 52 provides support for the contact member 30, so that the contact member 30 remains in a vertical state.

[0074] In this embodiment, the change in length of the second bend 52 affects the position of one side of it, thereby affecting the position of the contact member 30. The length of the second bend 52 can be changed according to actual needs, and this application does not impose any restrictions on it.

[0078] In this embodiment, the sensor 2 is located between the first contact convex surface 31 and the groove wall of the receiving groove 201. The first contact convex surface 31 can effectively press the sensor 2, ensuring that the sensor 2 and the electrical connection device 1 maintain a stable and effective connection in complex usage environments.

[0079] In this embodiment, the number of first contact convex surfaces 31 can be one or more, and this application does not impose any limitation.

[0080] In this embodiment, the shape of the first contact convex surface 31 can be a curved surface, a striped surface, a grid surface, etc., and this application does not impose any restrictions here.

The third bending portion 53 extends toward the welded member 20 and is located in the receiving groove 201.

[0082] In this embodiment, the first bending portion 51, the second bending portion 52 and the third bending portion 53 form a U-shaped irregular piece 50.

[0086] In this embodiment, the sensor 2 is located between the second contact convex surface 32 and the groove wall of the receiving groove 201. The second contact convex surface 32 can effectively press the sensor 2, ensuring that the sensor 2 and the electrical connection device 1 maintain a stable and effective connection in complex usage environments.

[0087] In this embodiment, the number of second contact convex surfaces 32 can be one or more, and this application does not impose any limitation on this.

[0088] In this embodiment, the shape of the second contact convex surface 32 can be a curved surface, a striped surface, a grid surface, etc., and this application does not impose any restrictions on it.

[0104] In this embodiment, the contact 30 and the receiving groove 201 fix the transmission end 22 of the sensor 2, preventing the transmission end 22 from falling off during biological movement and preventing disconnection. This ensures stable and reliable contact between the sensor 2 and the contact 30, thereby guaranteeing a stable and effective connection between the sensor 2 and the electronic components in complex operating environments. Furthermore, the length direction of the contact 30 is aligned with the length direction of the receiving groove 201, increasing the proportion of the contact 30 in the receiving groove 201 and thus increasing the contact area between the contact 30 and the sensor 2. This prevents the contact 30 from damaging the sensor 2, avoiding abnormal or non-transmittable signal transmission and improving the stability of the electrical signal between the electronic components and the sensor 2. Additionally, the mounting shell 200 covers the conductive element 100, ensuring the waterproof and dustproof connection circuit between the electronic components and the sensor 2. Moreover, the structure of this application is simple, consisting only of the mounting shell 200 and the conductive element 100, reducing the volume of the electronic connection device.

[0105] In this embodiment, the sensor 2, electronic components and electrical connection device 1 are housed in the housing, which makes the sensor 2, electronic components and electrical connection device 1 waterproof and dustproof, ensuring that the performance of the analyte detection device remains stable in complex and harsh environments, and can reduce the size of the analyte detection device and improve the comfort when wearing the analyte detection device.
