Electronic Card Connector Switch Actuation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic card connectors face issues with damage to mobile devices and SIM cards due to improper actuation of detection switches during tray insertion and removal, leading to power and data transmission problems.
Innovation Solution
An electronic card connection device featuring a connector, tray, and switch design where the switch is actuated only when the card is securely in contact, using an operating handle to ensure proper power and signal integrity, preventing damage by ensuring power is supplied after full contact and turned off before disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the detection switch is actuated during movement of the tray, then power and data transmission can be started, but damage to data or circuit of the electronic card or mobile device occurs
Solution Approach 1:
The switch actuating member is pre-positioned on the operating handle, and the switch is pre-positioned in the connector. When the tray is inserted, the operating handle automatically actuates the switch at the appropriate moment before full contact, preparing the power and data transmission system in advance. This preliminary action ensures that power and data transmission are activated at the optimal time without causing damage to the electronic card or device circuit.
2Loss of time
If the detection switch cannot be actuated timely due to too quick inserting and pulling of the tray, then power and data transmission are delayed, but damage to data or circuit still occurs
Solution Approach 1:
The operating handle serves as an intermediary mechanism between the tray and the detection switch. Instead of the tray directly actuating the switch, the operating handle mediates this interaction. The switch actuating member on the operating handle is designed to engage with the switch at a specific position during tray insertion or removal, ensuring timely and reliable actuation regardless of the speed of tray movement. This intermediary mechanism eliminates the timing issues that occur with direct actuation.
3Productivity
If power is supplied before full contact between electronic card and terminal, then data transmission can start earlier, but damage to electronic card or mobile device circuit occurs
Solution Approach 1:
The detection switch provides feedback about the contact status between the electronic card and terminal. The switch is positioned and actuated only when the electronic card makes full contact with the terminal, ensuring that power and data transmission are activated at the correct moment. This feedback mechanism prevents premature power supply that could cause circuit damage, while still enabling early data transmission as soon as proper contact is established.

AI summary
The present disclosure relates to an electronic card connection device and an electronic device. The electronic card connection device comprises a connector, an electronic card tray and a switch. The connector comprises a terminal housing and a shell, the shell and the terminal housing define a mating space. The electronic card tray being inserted in the mating space, the electronic card tray may comprise an electronic card receiving recess, a mounting block positioned in front of the electronic card receiving recess and an operating handle pivotally connected to the mounting block. The switch may be positioned alongside a rotation range of the operating handle, and partially protrudes into the rotation range allowing rotation of the operating handle to switch the state of the switch.
