Abstract

The utility model relates to an electric card connector, comprising a shell, a first body which detains a plurality of conductive terminals, a second body which is jawing fixed on the first body and a card drawing back mechanism. The card drawing back mechanism comprises a first card drawing back mechanism and a second card drawing back mechanism. After the electric card is inserted, the card margin actuates the first card drawing back mechanism and the first card drawing back mechanism moves to a stationary position, and the first card drawing back mechanism is locked to the position through the sliding orbit effect of a first metal card making department and a third body. When the card is drawn back, the pushing stalk of the second card drawing back mechanism is clicked, the pushing stalk is driven to move forward and actuate the sliding vane, the locking is rescinded, the electric card is drawn back, and a second metal card making department and a cam lock the pushing stalk. When pushing stalk is clicked a second time, the locking is rescinded, the pushing stalk is popped out and returns to the initial position. The electric card connector provided by the utility model makes the card drawing back more convenient and reliable.

Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers in particular to a kind of electronic card coupler with trip mechanism.

[background technology]

Electronic card coupler is widely used in the electric connection that realizes between electronic cards and the circuit board, prior art such as Japan special permission publication TOHKEMY 2000-251024 number and TOHKEMY 2000-251025 number etc., the electronic card coupler that these patents disclosed, be provided with the card receiving space that the power supply subcard inserts, be provided with in the receiving space when inserting electronic cards at card and contact, and can remove the contact site of above-mentioned contact when extracting with external connector; And a card push piece, it compresses the card front end face when inserting electronic cards, and when electronic cards when direction of insertion is advanced, accumulate card release elastic force; Wherein when having inserted electronic cards, the card push piece is locked on the progressive position, when again electronic cards when direction of insertion is pressed into, will remove above-mentioned locking, and discharge elastic force, make it to act on the front end face of electronic cards, make this electronic cards edge move back card in contrast to the direction of plug-in card.

Because the trip mechanism of above-mentioned electronic card coupler is by pressing electronic cards, to realize moving back the card function.But along with electronic technology develops to microminiaturization, the size of electronic cards is also small day by day.Directly press electronic cards in such cases and very easily it is pushed in the electronic installation fully, be difficult to press the electronic cards rear portion and to move back card with hand once more, even phenomenon such as card occurs eating.
