At the same time, it ensures the stability of the contact between the first terminal 21 and the second terminal 22 and the external device, which is beneficial to the stable transmission of signals.

[0048] In one embodiment, the first contact portion 2101 and the second contact portion 2200 are respectively provided with inclined guide surfaces 2103. The guide surfaces 2103 are inclined downward toward the rear end of the insulating housing 10 and are configured to guide the external expansion device into the plug slot 11.

[0049] By tilting the guide surface 2103 downward toward the rear end of the insulating housing 10, the insertion of external expansion devices can be guided, making the insertion process smoother, reducing resistance and risk of damage during insertion, and improving the ease of use and reliability of the connector.

[0050] In one embodiment, the first retaining portion 211 is integrally formed with the first lever arm 210, and the second retaining portion 221 is integrally formed with the second lever arm 220.
