[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 connectors generally consist of multiple terminals and a housing. Typically, the terminals and housing are separate structures, such as the Chinese Utility Model Patent for an Electronic Connector and Sensor Connection Structure for a Blood Glucose Meter (Application No.: 202420039334.9), or the terminals and housing are integrated structures, such as the Chinese Utility Model Patent for a Compact Connector (Application No.: 202421695146.8). However, in both of these types of connectors, the multiple terminals are staggered along the slots. This design increases the longitudinal dimension of the housing, resulting in a larger overall product size and increased space occupied by the device. 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 in existing connectors, most of the terminals are arranged alternately along the slot, which increases the longitudinal dimension of the housing, resulting in a larger product size and increased space occupied by the whole machine.

[0008] Furthermore, the housing is provided with a step placed between the slot and the notch, and the connecting section is bent relative to the snap-fit ​​section and abuts against the step.

[0009] Furthermore, the connecting segment is provided with two symmetrically distributed lugs, the connecting segment is placed between the two lugs, and the length of the connecting segment is greater than the depth of the step.

[0010] Furthermore, the height of the step is less than the height of the shell.

[0011] Furthermore, the bottom surface of the extension platform is provided with at least one downwardly extending positioning post.

[0012] Furthermore, the circuit board is provided with a socket for mounting the housing, a positioning hole corresponding to the positioning post, and a clearance hole for accommodating the sensor.

[0019] 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.

[0020] like Figures 1 to 5 As shown, an electronic connector includes a housing 1 and a plurality of terminals 2. The housing 1 is provided with a slot 11 for inserting a sensor 4 along its length and a plurality of mounting grooves 12 symmetrically distributed on both sides of the slot 11. The terminal 2 includes an abutting section 21 that extends into the slot 11 and a connecting section 24 that extends out of the housing 1 and is used to connect with a circuit board 3. The terminal 2 is inserted into the mounting groove 12, and the slot 11 is connected to the mounting groove 12.

[0021] With the above scheme, the housing 1 is provided with a slot 11 for inserting the sensor 4 and a plurality of mounting slots 12 symmetrically distributed on both sides of the slot 11. The slot 11 and the mounting slots 12 are connected. The terminal 2 is inserted into the mounting slot 12 so that the terminal 2 abuts against the circuit board 3. The symmetrical distribution of the terminal 2 can reduce the longitudinal dimension of the housing 1, making the product smaller in size, thereby reducing the space occupied by the whole machine.

[0022] In this embodiment, the housing 1 is made of plastic, and the terminals 2 are made of metal. The terminals 2 are inserted into the symmetrical mounting slots 12 on both sides of the slot 11, so that multiple terminals 2 form two rows. The abutment section 21 extends into the slot 11, and after the pin of the sensor 4 is inserted into the slot 11, the pin abuts against the contact section. The connecting section 24 extends out of the housing 1 and is soldered and fixed to the circuit board 3. The terminals 2 are inserted into the mounting slots 12, which enables the connector to maintain good stability when subjected to external impact or vibration. The design of the slot 11 and the mounting slots 12 enables the pin of the sensor 4 and the terminals 2 to be accurately inserted into the predetermined position, ensuring that the sensor 4 and the connector are correctly and accurately connected.

[0023] like Figures 2 to 4 As shown, in one specific embodiment of the improvement, the terminal 2 further includes an elastic section 22 connected to the abutment section 21 and a snap-fit ​​section 23 connected to the elastic section 22. The snap-fit ​​section 23 is connected to the connecting section 24. The mounting groove 12 includes a receiving hole 121, a slot 122 and a notch 123 connected in sequence. The receiving hole 121 is connected to the slot 11 so that the elastic section 22, the snap-fit ​​section 23 and the connecting section 24 are respectively accommodated in the receiving hole 121, the slot 122 and the notch 123.

[0024] Specifically, the end of the abutment section 21 is oriented upwards and bent outwards, facilitating the insertion of the sensor 4's pin from top to bottom and ensuring a stable connection between the sensor 4 and the connecting machine. Simultaneously, the two symmetrical terminals 2 on the left and right can clamp the pin, preventing loosening or detachment during operation. The receiving hole 121 penetrates the housing 1 vertically, preventing the elastic section 22 from contacting the housing 1 and providing space for the elastic expansion and contraction of the abutment section 21 and the elastic section 22. The slot 122 is adapted to the locking section 23, and the width of the slot 122 is greater than the width of the receiving hole 121 and the notch 123. When the locking section 23 of the terminal 2 is aligned with the slot 122 and inserted, it can be inserted straight in, which is simple and precise. It can also limit the left and right movement of the terminal 2, preventing offset or loosening after insertion, and improving the efficiency and accuracy of terminal 2 insertion. Furthermore, based on the connection section 24 being housed in the notch 123 and welded to the circuit board 3, it can limit the upper and lower movement of the terminal 2, enhancing the stability of the terminal 2 connection and installation.

[0025] like Figure 2 and Figure 3 As shown, in one specific embodiment of the improvement, the two symmetrical sides of the housing 1 are provided with grooves 13 along the height direction, so that the upper ends of the two sides of the housing 1 form protruding extension platforms 14, and the notches 123 penetrate the extension platforms 14, so that the grooves 13 and the notches 123 are connected.

[0026] Specifically, the groove 13 is designed to form a T-shaped structure in the cross section at the center of the housing 1. An extension platform 14 is formed on the upper part of the housing 1, extending outward along the width direction. The notch 123 of the mounting groove 12 passes through the extension platform 14, so that the extension platform 14 forms multiple independent bosses. The connecting section 24 is placed between two adjacent bosses, which can provide space for the installation of the connecting section 24.

[0027] like Figures 2 to 4 As shown, in one specific embodiment of the improvement, the housing 1 is provided with a step 15 placed between the slot 122 and the notch 123, and the connecting section 24 is bent relative to the snap-fit ​​section 23 and abuts against the step 15.

[0028] Specifically, step 15 is placed between slot 122 and groove 13, notch 123 is connected vertically to groove 13, and step 15 has an inclined surface at one end near slot 11 to assist in the insertion of terminal 2 and prevent scratching terminal 2. The top surface of step 15 is flat. When connecting section 24 is placed at notch 123, connecting section 24 fits against the top of step 15, so that step 15 can provide physical support and accurately position the bending of connecting section 24.

[0029] like Figures 2 to 4 As shown, in one specific embodiment of the improvement, the connecting segment 24 is provided with two symmetrically distributed lugs 231, the connecting segment 24 is placed between the two lugs 231, and the length of the connecting segment 24 is greater than the depth of the step 15.

[0030] Specifically, the connecting segment 24 is bent relative to the snap-fit ​​segment 23. The snap-fit ​​segment 23 is a vertically arranged planar structure. In practical applications, the two lugs 231 can facilitate the insertion or removal of the terminal 2. When the connecting segment 24 is formed, a bending cut is set from the top of the snap-fit ​​segment 23 downwards, so that the connecting segment 24 forms a tear structure. The length of the connecting segment 24 is greater than the depth of the step 15, that is, the depth of the cut is greater than the setting depth of the step 15, ensuring that the connecting segment 24 can fit against the top surface of the step 15 after bending. At the same time, the inclined surface of the step 15 can also prevent the connecting segment 24 from being scraped or blocked, ensuring that the terminal 2 can be tightly installed in the housing 1.

[0031] like Figures 2 to 4 As shown, in one specific embodiment of the improvement, the height of step 15 is less than the height of housing 1.

[0032] Specifically, based on the notch 123 formed above the step 15, the height of the step 15 is less than the height of the housing 1. Also, based on the length of the connecting segment 24 being greater than the depth of the step 15, and the connecting segment 24 having a tear structure relative to the snap-fit ​​segment 23, in practical applications, the bending depth of the connecting segment 24 can be adjusted according to customer needs. That is, the bending reference point of the connecting segment 24 is changed, allowing the length and height of the bent portion of the connecting segment 24 to be adjusted. At this time, the connecting segment 24 can be bent according to the height setting of the step 15, which can improve the adaptability of the terminal 2. The change of the bending reference point of the connecting segment 24 can change the bending area of ​​the connecting segment 24, that is, the area of ​​the connecting segment 24 and the circuit board 3 can also be adjusted according to customer needs.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, in one specific embodiment of the improvement, the bottom surface of the extension platform 14 is provided with at least one downwardly extending positioning post 16, and the circuit board 3 is provided with an insertion hole 31 for mounting the housing 1, a positioning hole 32 corresponding to the positioning post 16, and a clearance hole 33 for accommodating the sensor 4.

[0034] Specifically, multiple protrusions are formed by the notch 123 penetrating the extension platform 14. A positioning post 16 is set below one of the protrusions on the left and right sides, so that the two positioning posts 16 are symmetrical. The cross-section of the housing 1 is a T-shaped structure, so that the lower part of the housing 1 can be embedded in the insertion hole 31. The extension platform 14 is placed above the circuit board 3, and the connecting section 24 is attached to the circuit board 3. The positioning post 16 is precisely embedded in the positioning hole 32, which can limit the housing 1 after installation and prevent loosening or displacement. The clearance hole 33 is set on the side of the insertion hole 31 and connected to it, which facilitates the insertion and removal of the sensor 4 pin. It makes full use of the space of the circuit board 3 thickness and further reduces the space occupied by the whole machine.

[0035] 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.
