The ear button 4 includes a base portion 41. Two pivoting shafts 42 are disposed on two sides of the base portion 41. An ejector portion 43 is disposed under the base portion 41, and a latching portion 44 is disposed on the upper portion of the base portion 41. One of the outer sides of the 44 portion 45. When the ear button 4 is inserted into the recess 221, the pivot shaft 42 enters the pivot hole, and the ear button 4 is rotatable about the pivot shaft 42. The ejector portion 43 Located within the slot 212.

Referring to the second to fourth figures, when the electronic card 1 is inserted into the card edge connector 100, the electronic card 1 enters the slot 212, and the foolproof portion 23 enters the The recess 11 prevents the user from inserting the electronic card 1 backward. Pressing the electronic card 1 , the bottom of the electronic card 1 firstly abuts the ejector portion 43 of the ear button 4 , and presses the ejector portion 43 to rotate the ear button 4 inwardly. The bottom edge 10 is first inserted between the two rows of terminals 3, and the contact portion 32 contacts the metal pad 13. At this time, the flat portion 122 at the recessed portion 12 has not entered between the two rows of terminals 3. Continue to press the electronic card 1, the flat portion 122 of the recessed portion 12 is inserted between the two rows of terminals 3, while the ear button 4 is rotated to a vertical position, and the latching portion 44 holds the electronic card A notch 151 of the side edge 15 of 1 to lock the electronic card 1. At this time, the step portion 24 enters the recessed portion 12 and cooperates with the recessed portion 12 to prevent the electronic card 1 from being skewed, and the inclined portion 243 abuts against the slope 121 of the electronic card 1 to prevent the electronic card 1 Displacement occurs in the longitudinal direction of the insulative housing 2, and at this time, the flat portion 122 abuts against the first step surface 241.

In the above process, since the bottom edge 10 and the flat portion 122 of the electronic card 1 are sequentially inserted between the two rows of terminals 3, the clamping force generated by the terminal 3 on the electronic card 1 is divided. At the stage, the force received by the electronic card 1 can be buffered, and the insertion force can be reduced, so that the user can insert the electronic card 1 into the card edge connector 100 with a small force.

In summary, the creation meets the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the foregoing embodiments, and any equivalent modifications or changes made by those skilled in the art to the spirit of the present invention are It should be covered by the following patent application.
