Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electronic connector. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to their personal health. As a result, many families are equipped with blood glucose meters. In order to obtain accurate data when conducting blood glucose tests, continuous blood glucose monitoring is generally used. The blood glucose sensor is inserted into the body through a device, and the sensor transmits the data back to the meter.

[0003] Currently, existing CGM sensors generally consist of terminals and a housing. Typically, the terminals and housing are separate structures, such as the Chinese Utility Model Patent "An Electronic Connector and Sensor Connection Structure for a Blood Glucose Meter" (application number: 202420039334.9), or the terminals and housing are integrated structures, such as the Chinese Utility Model Patent "A Compact Connector" (application number: 202421695146.8). However, the terminals in the above two types of connectors have poor elasticity. When the sensor is inserted into the slot and abuts against the arc-shaped section of the terminal, the outward-curved section of the terminal bends outward based on the curved part. This can easily lead to breakage during long-term insertion and removal of the sensor pin, reducing the service life of the terminal. Utility Model Content

[0004] The purpose of this utility model is to provide an electronic connector that addresses the shortcomings of the existing technology by solving the technical problem that the terminals of the existing connectors have poor elasticity and are prone to breakage during long-term insertion and removal of sensor pins, thus reducing the service life of the terminals.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electronic connector, including a housing and a cover disposed on the upper side of the housing, the housing having a placement part for accommodating sensors, two rows of terminals being fixedly connected in the placement part by in-mold forming, the terminals being staggered and separating the placement part into several cavities, a number of positioning posts for clamping sensors being staggered and fixedly connected on the lower surface of the cover, the positioning posts being precisely inserted into the cavities when the cover and housing are assembled, the housing having slots with upward openings for inserting sensors, the slots being respectively disposed on opposite sides of the housing, the terminals including a contact section, a U-shaped elastic section and an L-shaped fixing section connected in sequence, the contact section being continuously bent downwards and inwards, the front ends of the contact section, elastic section and fixing section all extending into the placement part.

[0006] Furthermore, the terminal also includes a connecting section connected to the fixed section, the fixed section and the connecting section are connected to form a Z-shaped structure, and the connecting section extends out of the housing.

[0007] Furthermore, the width of the connecting segment is greater than the width of the fixed segment.

[0008] Furthermore, the terminal is a metal spring with a multi-bent structure.

[0009] Furthermore, a circuit board is connected to the lower surface of the housing, and the circuit board is welded and fixed to the connecting section.

[0010] Furthermore, the circuit board is provided with connection points corresponding to the upper and lower elastic segments.

[0011] Compared with the prior art, the beneficial effects of this application are as follows: By setting an elastic segment between the contact segment and the fixed segment of the terminal, the terminal forms a long elastic lever arm with a U-shaped elastic segment, which can form a buffer when the contact segment abuts against the sensor, thereby enhancing the elasticity of the terminal. It can better adapt to the long-term insertion and removal of the sensor pin, reduce the risk of the terminal breaking easily, and extend the service life of the connector.

[0017] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings, and to understand in detail how to solve the problems raised in the background art.

[0018] like Figures 1 to 5 As shown, an electronic connector includes a housing 1 and a cover 2 disposed on the upper side of the housing 1. The housing 1 is provided with a placement part 11 for accommodating a sensor 5. Two rows of terminals 3 are fixedly connected in the placement part 11 by in-mold forming. The terminals 3 are staggered and divide the placement part 11 into several cavities 12. Several positioning posts 21 for clamping the sensor 5 are staggered and fixedly connected to the lower surface of the cover 2. When the cover 2 is assembled with the housing 1, the positioning posts 21 are inserted into the cavities 12. The housing 1 is provided with slots 13 with the opening facing upward for inserting the sensor 5. The slots 13 are respectively disposed on opposite sides of the housing 1. The terminals 3 include a contact section 31, a U-shaped elastic section 32 and an L-shaped fixing section 33 connected in sequence. The contact section 31 is continuously bent downward and inward. The front ends of the contact section 31, the elastic section 32 and the fixing section 33 all extend into the placement part 11.

[0019] With the above solution, by setting an elastic segment 32 between the contact segment 31 and the fixed segment 33 of the terminal 3, the terminal 3 forms a long elastic arm with a U-shaped elastic segment 32, which can form a buffer when the contact segment 31 abuts against the sensor 5, thereby enhancing the elasticity of the terminal 3, which can better adapt to the long-term insertion and removal of the sensor 5 pin, reduce the risk of the terminal 3 being easily broken, and extend the service life of the connector.

[0020] like Figure 2As shown, in this embodiment, after the pin of the sensor 5 is inserted into the slot 13, the pin abuts against the contact section 31, and the two rows of terminals 3 are distributed on the left and right sides of the pin. The front end of the fixing section 33 extends into the placement part 11, and the rear end is fixed to the housing 1. An integral structure is formed by in-mold molding technology, so that the front end of the fixing section 33 also becomes part of the elastic lever arm.

[0021] like Figure 1 and Figure 2 As shown, in the above technical solution, the placement part 11 is divided into several cavities 12 by staggered terminals 3. This design effectively utilizes the space inside the housing 1 and makes the entire connector structure more compact. The positioning posts 21, which are staggered and fixed on the lower surface of the cover 2, match the cavities 12 in the housing 1. When the cover 2 and the housing 1 are assembled, the positioning posts 21 can be accurately inserted into the cavities 12 and isolate the terminals 3 from each other, thereby achieving a stable connection and precise positioning. This design improves the assembly efficiency of the connector and avoids mutual interference between components. The terminals 3 are fixed inside the housing 1 by in-mold molding technology. This fixing method enhances the connection strength between the terminals 3 and the housing 1 and enables the entire connector to maintain good stability when subjected to external impact or vibration, effectively extending the service life of the equipment. The slot 13 allows the sensor 5 to be accurately inserted into the predetermined position, ensuring that the sensor 5 and the connector are correctly and accurately connected. This ensures that the sensor 5 is not easy to loosen or fall off during operation, thereby ensuring the reliability of the connection.

[0022] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, the terminal 3 further includes a connecting section 34 connected to the fixed section 33. The fixed section 33 and the connecting section 34 are connected to form a Z-shaped structure, and the connecting section 34 extends out of the housing 1.

[0023] Specifically, based on the U-shaped structure of the elastic segment 32, the contact segment 31 and the fixing segment 33 are respectively located at the ends of the left and right sides of the elastic segment 32. The contact segment 31 is bent downward and inward relative to the elastic segment 32, so that the bent end of the contact segment 31 is set inward, which can accurately align and engage the pin of the sensor 5, ensuring a stable connection between the sensor 5 and the connector. Furthermore, the terminals 3 on the left and right sides clamp the pin together under the elastic action, preventing the sensor 5 from loosening or falling off during operation and ensuring the stability of the connection. The fixing segment 33 has an L-shaped structure, so that the connecting segment 34 is perpendicularly connected to the end of the fixing segment 33. At the same time, part of the connecting segment 34 is also fixed to the bottom surface of the frame of the housing 1, ensuring that the bottom surface of the connecting segment 34 is exposed and extends outward to the outside of the housing 1, ensuring the stability of the spring clip fixation and facilitating the assembly of the connector. The pin of the sensor 5 can be disassembled by simply inserting and removing it from the connector, reducing the complexity and cost of maintenance.

[0024] like Figure 3 and Figure 5 As shown, in one specific embodiment of the improvement, the width of the connecting segment 34 is greater than the width of the fixed segment 33.

[0025] Specifically, the width of one end of the fixed section 33 and the connecting section 34 gradually increases, making the width of the connecting section 34 greater than the width of the fixed section 33. This widens the welding feet of the terminal 3, increasing the contact area during welding and improving the welding strength and connection stability.

[0026] like Figures 3 to 5 As shown, in one specific embodiment of the improvement, terminal 3 is a metal spring with a multi-bent structure.

[0027] Specifically, both the housing 1 and the cover 2 are made of plastic. The cover 2 and the positioning posts 21 are an integral structure, enhancing structural strength. The positioning posts 21 are staggered on the bottom surface of the cover 2. When the cover 2 is installed on top of the housing 1, the positioning posts 21 can clamp the sensor 5, allowing the terminal 3 to engage with the positioning posts 21 in a predetermined position, maintaining installation stability and accuracy, and reducing the risk of component loosening or damage due to vibration or impact. The contact section 31 and the elastic section 32 are connected to form an S-shaped structure, and the fixed section 33 and the connecting section 34 are connected to form a Z-shaped structure. The elastic section 32 is U-shaped and open. With the opening facing upwards, the fixed section 33 is L-shaped, so that after the elastic section 32 and the fixed section 33 are connected, they form two U-shaped structures with opposite openings on the left and right sides. This forms a multi-bending structure for the elastic arm of the terminal 3, making the terminal 3 appear as a "snake-like structure". In actual production, with this structure design, the height of the connector in the vertical direction can be made to less than 0.8mm. Since the sensor 5 is worn on the human body, the heavier it is, the worse the feeling will be, and there is also a risk of it falling off during exercise. This structural design can provide users with a better experience and make CGM's transmitter smaller and smaller, which can also meet users' demand for a thinner sensor 5.

[0028] like Figure 1 and Figure 2 As shown, in one specific embodiment of the improvement, a circuit board 4 is connected to the lower surface of the housing 1, and the circuit board 4 is welded and fixed to the connecting section 34.

[0029] Specifically, the circuit board 4 and the connecting section 34 are soldered and fixed using SMT (Surface Mount Technology), which ensures a strong and reliable electrical connection between the circuit board 4 and the terminal 3, guarantees stable transmission of electrical signals, and provides a support structure for the circuit board 4.

[0030] like Figure 2 As shown, in one specific embodiment of the improvement, the circuit board 4 is provided with connection points 41 that correspond to the upper and lower parts of the elastic segment 32.

[0031] Specifically, there are 5 terminals 3. Each terminal 3 has a corresponding connection point 41 below the bend of the U-shaped elastic segment 32. The bottom of the elastic segment 32 at its initial position has a small gap with the connection point 41. In actual application, when the sensor 5 pin is inserted into the slot 13, the contact segment 31 abuts against the pin, which compresses the contact segment 31 and the elastic segment 32. The bottom of the elastic segment 32 will contact the connection point 41, which can further increase the stability of the connection between the terminal 3 and the circuit board 4, and also strengthen the firmness of the terminal 3 clamping the sensor 5.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
