Electronic card connector against accidental card ejection

Abstract

The invention discloses an electronic card connector capable of preventing a card from withdrawn accidentally. The electronic card connector comprises an insulation seat, contact terminals, a shielding case and a card support. A card withdrawing limiting part is arranged on the upper surface of the card support, and an elastic arm is formed on the top wall of the shielding case. A card stopping part is arranged at the free end of the elastic arm, and the card stopping part is matched with the card withdrawing limiting part of the card support. For the elastic arm, a push rod is arranged in a second containing space beside the insulation seat. The push rod comprises a body part, an operation part, a butting pushing part, a reset pushed part and a first stroke limit part which is used for preventing the push rod from resetting and being disengaged out, wherein the operation part, the butting pushing part, the reset pushed part and the first stroke limit part are arranged on the body part. A push rod reset elastic mechanism and a second stroke limit part are arranged in the second containing space, and an automatic card support pop-up mechanism is arranged for the card support. Accordingly, in the card inserting state, the card stopping part is buckled on the card withdrawing limiting part to lock the card support, and the phenomenon that the card support is disengaged when a product is shaken, accidentally falls and the like is avoided. In the card withdrawing process, the push rod is pushed forwards so that a clamping state can be removed, operation is convenient and fast, and the card withdrawing structure is simple.

Description

technical field [0001] The invention relates to the technology in the field of electronic card connectors, in particular to an electronic card connector for preventing accidental withdrawal of cards. Background technique [0002] With the development of electronic products, electronic card connectors have also been widely used. For example, many mobile phones are usually equipped with drawer-type electronic card connectors. The current drawer-type electronic card connectors generally include insulating seats, which are arranged on insulating The contact terminal in the seat, the shielding shell covering the outside of the insulating seat, the card holder for accommodating the electronic card, and the card ejection mechanism for controlling the withdrawal of the card holder; , it is very prone to undesirable phenomena such as Cato falling off, which has caused unnecessary troubles to people. [0003] Therefore, it is urgent to work out a new technical solution to solve the a...
