Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electronic connector for dynamic blood glucose monitoring devices. Background Technology

[0002] In the field of medical testing, blood glucose monitoring devices play an indispensable role in the monitoring and treatment of diabetes and related diseases. Among these devices, the connector, a key component, serves the crucial function of connecting the test strip to the main body of the device. It acts as a bridge, ensuring that the test strip can accurately and stably work in conjunction with the internal detection sensor. The connector's structural design and performance directly affect the accuracy and reliability of blood glucose testing.

[0003] Existing continuous glucose monitoring devices typically come with connectors for attaching test strips. However, in practical use, these connectors have revealed some serious problems, such as test strip warping due to uneven force distribution. This is caused by uneven pressure distribution within the connector or excessive local friction during test strip insertion. Warping alters the contact between the test strip and the glucose sensor, thus affecting the accuracy of the test results. For example, warping may lead to poor local contact, causing deviations in the glucose signal acquired by the sensor, ultimately providing incorrect information for medical diagnosis.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.

[0030] like Figures 1 to 8 As shown in this embodiment, an electronic connector for a dynamic blood glucose monitoring device is mounted on the PCB board of the dynamic blood glucose monitoring device.

[0031] A first clamping terminal 2 is vertically inserted into the first terminal slot 12; a second clamping terminal 3 is vertically inserted into the second terminal slot 13; the first clamping terminal 2 has a first clamping opening 21; the first clamping opening 21 is provided with a first contact 22; the two first contacts 22 are located on one side of the test paper slot 11; the second clamping terminal 3 has a second clamping opening 31; the second clamping opening 31 is provided with a second contact 32; the two second contacts 32 are located on the other side of the test paper slot 11.

[0032] In this embodiment, the electronic connector for a dynamic blood glucose monitoring device is used such that, in actual use, the test strip is vertically inserted into the test strip slot 11. At this time, the test strip is inserted into the first clamping port 21 of the first clamping terminal 2 and the second clamping port 31 of the second clamping terminal 3. The first contacts 22 of the two first clamping terminals 2 are in contact with one surface of the test strip, and the second contacts 32 of the two second clamping terminals 3 are in contact with the opposite surface of the test strip, thereby forming a mutual pressure structure that clamps the test strip from both sides.

[0033] In addition, in this embodiment, the first clamping terminal 2 and the second clamping terminal 3 are both vertically embedded on the base 1, thereby saving the space occupied by the terminals in the horizontal direction and reducing the spacing between the terminals to achieve a small spacing effect, making the overall structure smaller and saving space.

[0035] A first contact 22 of one of the first clamping terminals 2 is located between the first slot segment 111 and the second slot segment 112; a first contact 22 of another of the first clamping terminals 2 is located between the fourth slot segment 114 and the fifth slot segment 115; a second contact 32 of one of the second clamping terminals 3 is located between the second slot segment 112 and the third slot segment 113; and a second contact 32 of another of the second clamping terminals 3 is located between the third slot segment 113 and the fourth slot segment 114.
