Movable Shielding Tray for Card Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing card connectors face challenges in facilitating easy push-in and pull-out operations of small SIM cards while maintaining effective shielding to prevent interference, as the reduced operational space and exposed surface area compromise the ease of card extraction and anti-interference performance.
Innovation Solution
A card connector design featuring a base, shielding sleeve, and movable shielding tray that defines distinct directions for insertion and extraction, allowing for electrical connection and providing a larger operational space for card removal while minimizing exposed area, thus enhancing shielding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the card connector is designed with a compact structure to reduce device size, then the device occupies less space, but the operational space for card insertion and extraction is reduced making it difficult for users to operate
Solution Approach 1:
The shielding tray is designed to be movable relative to the base, transitioning between a first position during card insertion/extraction and a second position during data transmission. This dynamic structure allows the connector to provide adequate operational space when needed while maintaining compact dimensions when the card is inserted, resolving the contradiction between device size and ease of operation.
2Ease of operation
If the card connector provides a large operational space for easy card extraction, then users can easily remove cards, but the exposed surface area of the card increases reducing shielding performance
Solution Approach 1:
The shielding tray moves between positions: in the first position, it allows adequate card exposure for easy user extraction; in the second position, it covers the card surface area to provide effective electromagnetic shielding during data transmission. This dynamic positioning resolves the contradiction between ease of operation and anti-interference performance.
Solution Approach 2:
The card connector is segmented into multiple functional components: a base, a movable shielding tray, and a card receiving chamber. The shielding tray can be independently moved to different positions, allowing the system to provide either operational access or shielding coverage as needed, resolving the contradiction between card extraction ease and electromagnetic protection.
3Object-affected harmful factors
If the shielding tray covers a large area of the card during data transmission, then anti-interference performance is improved, but the operational space for card manipulation is reduced
Solution Approach 1:
The shielding tray is designed to dynamically change its position based on operational requirements. During data transmission, it moves to the second position to cover the card and provide maximum shielding. During card insertion or extraction, it moves to the first position to provide adequate operational space. This dynamic behavior resolves the contradiction between shielding effectiveness and ease of card manipulation.

AI summary
A card connector and a method of manufacturing the card connector are provided. In one embodiment, the card connector comprises a base; a shielding sleeve connected to the base, the base and the shielding sleeve defining a first direction for inserting a card and a second direction opposite to the first direction for extracting the card; and a shielding tray for receiving the card, the shielding tray being movable relative to the base in the first direction or the second direction, wherein the card connector is operable to electrically connect to the card if the card reaches a position of insertion along the first direction. The card connector is capable of facilitating the push-in and pull-out operations of a card by a user, while minimizing an exposed area of the card so as to improve the shielding performance.
