AI Technical Summary

Technical Problem

The existing design of electronic display card slots fails to effectively address the needs for thinner electronic display paper, precise alignment, and convenient placement and removal, resulting in insufficient guidance and positioning accuracy and poor connection stability.

Method used

The mounting slot for inserting display paper is formed by the snap-fit of the card slot body and the guide component. The thickness of the guide slot gradually decreases along the insertion direction. A paper pick-up port is provided for easy paper picking and putting. The connection port, together with the gold finger female, ensures a stable conductive connection. The annular boss and the flared structure enhance the connection stability, and the positioning ribs achieve precise positioning and error prevention.

Benefits of technology

It achieves precise guidance, convenient placement and removal, and stable connection of the display paper, avoiding insertion deviation and damage, and improving the overall structural stability and ease of use of the electronic display card slot.
