[embodiment]
Shown in Fig. 1 to 5, meet a kind of card connector 100 of the present utility model, it comprises insulating base frame 10, be coated on the metal shell 20 of insulating base frame 10, be immobilizated in some signal terminals 30 on the insulating base frame 10, be immobilizated in the detecting of first on the insulating base frame 10 terminal 40, be installed on the trip mechanism 50 on the insulating base frame 10.
Described insulating base frame 10 comprises long and narrow base portion 11, a pair of side arm 12 that extends from base portion 11 two ends, be positioned at the middle part of a pair of side arm 12 and connect the installation portion 13 of this a pair of side arm 12.Described base portion 11 is provided with a draw-in groove 111 in the longitudinal direction, is provided with a pair of through hole 112 that runs through insulating base frame 10 in the described draw-in groove 111.
Described metal shell 20 comprises roof 21, parallel pair of sidewalls 22 of extending in the same way, the rear wall 23 that extends from roof 21 opposite sides from roof 21 relative both sides.Described metal shell 20 cooperate back formation to power with insulating base frame the receiving space with opening 24 25 that subcard (not shown) inserts.Described roof 21 is provided with the second detecting terminal 211 of in card connector 100 diagonally extending, the rake 213 that the described second detecting terminal 211 comprises the connecting portion 212 that extends along the electronic cards direction of insertion from metal shell 20, extend to card connector 100 inner inclination from connecting portion 212, continues the contact arm 214 that extends from rake 213.In the present embodiment, the second detecting terminal 211 is elastic piece structures, and metal shell 20 is provided with a pair of second detecting terminal 211.
Described signal terminal 30 is immobilizated in the installation portion 13 on the insulating base frame 10, and described signal terminal 30 comprises the docking section 31, the holding parts 32 that is immobilizated in the installation portion 13 of insulating base frame 10 that electrically connect with electronic cards, can be welded to the welding foot 33 on the circuit board.
In the described first detecting terminal, the 40 elongated draw-in grooves 111 that are installed on the insulating base frame 10, therefore thereby the first detecting terminal 40 is positioned at the side of signal terminal 30 away from opening 24, will reduce the width of electronic card coupler 100 under the situation of the side that switch terminal is installed on insulating base frame 10.The first detecting terminal 40 and the second detecting terminal 211 form switch terminal, second detecting terminal 211 resilient abutment on the first detecting terminal 40, the described first detecting terminal 40 comprises the contact site 41 of the strips that electrically contacts with the contact arm 214 of the second detecting terminal 211, from contact site 41 that extend downwards and be fastened on the insulating base frame 10 112 fixing pin 42 in the through hole, the horizontally extending welding foot 43 that is welded on the external circuit board also downwards from contact site 41 two ends.Described contact site 41 is provided with salient point 411, and described salient point 411 electrically contacts with second contact arm of detecting on the terminal 211 214.When electronic cards is not inserted card connector, salient point 411 on described second detecting terminal 211 and the contact site 41 keeps electrically connecting, when electronic cards is inserted, electronic cards outwards struts the second detecting terminal 211 gradually, when electronic cards continues inwardly to insert, electrically connect thereby make the contact arm 214 of the second detecting terminal 211 disconnect, thereby can know that electronic cards inserted in the card connector 100 with salient point 411.
