Description

Electrical connector

This creation relates to an electrical connector, and more particularly to an electrical connector for use in blood glucose testing.

With the rapid evolution of technology, there has been considerable progress in the diagnosis of disease or health. However, the above-mentioned diagnosis relies on the reading of the detecting device, and the blood glucose testing device is an indispensable health diagnostic instrument for daily life for patients who have abnormal blood glucose and need to monitor blood sugar levels for a long time.

Take blood sugar test in diabetic patients as an example. First, insert the blood glucose test card into the test card connector of the blood glucose test device, and then take a needle on the patient (such as a finger) to take a blood sample. Next, the blood sample is dropped on the blood sugar test card, and the blood sample is reacted with the biological enzyme in the blood sugar test card, and converted into an electronic signal input blood sugar test device, thereby calculating the blood sugar level.

After the test is completed, the user (the caregiver or the patient itself) will use the blood glucose test card to perform the card withdrawal operation through the card return mechanism of the test card connector to discard the blood glucose test card.

However, due to the large number of brand specifications of blood glucose testing devices, the blood glucose test cards vary in size between brands, so they cannot be used for testing each other. For the manufacturer of the connector, if the requirements of different manufacturers are to be met, the connector molds of different specifications need to be opened separately, so that the unit price of the test card connector is increased, and the manufacturing management is inconvenient, so how to design and manufacture A test for blood glucose test cards of different sizes has become an issue that needs to be overcome and solved.

It can be seen that there are still many shortcomings in the above-mentioned conventional connectors, which is not a good designer, and needs to be improved.

The above and other objects, features and advantages of the present invention will become more apparent and understood.

Referring to the first to fifth figures, the electrical connector of the present invention comprises: a body 1 made of an insulating material, the body 1 is formed with a card space 11 and a card space. 11 is formed with a card insertion opening 12 at the front end, and a plurality of conductive terminal receiving slots 13 are formed at the bottom end of the card insertion space 11, and the conductive terminal receiving groove 13 is inserted through the rear end of the body 1 (away from the insertion slot) For inserting the conductive terminal, one side of the card space 11 is formed with a positioning surface 14; and the bottom end of the body 1 is provided with a slot 15, and the slot 15 and the card space 11 is connected to each other; a plurality of conductive terminals 2, the conductive terminal 2 includes a fixing portion 21 fixed to the body 1 and a soldering portion 22 and a contact portion 23 extending from opposite ends of the fixing portion 21, respectively, in this embodiment, The conductive terminal 2 is inserted into the set position through the fixing portion 21 from the conductive terminal receiving groove 13 of the body 1. The soldering portion 22 is used for soldering and fixing on the circuit board, and the structure of the contact portion 23 is from the fixing portion 21. After the reverse bending is extended, the protrusion is further disposed, and the end 24 of the conductive terminal 2 after bending is directed toward the card space 11 The rear end is disposed in a direction away from the card insertion opening, and the structure of the contact portion 23 is configured to prevent the bending deformation of the conductive terminal 2 from being damaged due to an incorrect angle when the test card is inserted; and the elastic positioning terminal 3 includes the insertion a fixing portion 31 on the main body 1 and a welded portion 32 and an elastic portion 33 extending from both sides of the fixing portion 31, and the end of the elastic portion 33 Then, a top abutting portion 34 is formed.
