[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model connector trip mechanism is further specified.

See also Fig. 1 and Fig. 6, the connector at the utility model connector trip mechanism place comprises an insulating body 1, is located in the terminal 2 in this insulating body 1, and is used to move back the trip mechanism 3 of card and the lid 4 that part is covered this trip mechanism 3.

One side of described insulating body 1 is provided with a front end and has the rectangle accepting groove 11 that inserts mouth 110, one guide channel 12 that communicates with this accepting groove 11, and the support slot 13 that connects this accepting groove 11 and guide channel 12, also be provided with three not rectangular through-hole 14 of conllinear at homonymy, the line at three through hole 14 centers forms a right angle triangle, and this through hole 14 is used for inserting holds described lid 4, in addition, on the long right-angle side of described right-angled triangle, convex with a drive-connecting shaft 15, be provided with one section slideway 16 concentric with this drive-connecting shaft 15 in the outside of drive-connecting shaft 15, also be provided with a receiving space 17 on the next door of slideway 16, one end wall 171 of this receiving space 17 is linearly, and a sidewall 172 is curved.

Described trip mechanism 3 comprises an action bars 31 and the elastomer 32 that is placed on this action bars 31, and an actuator 33.Wherein, described action bars 31 is directly tabular, comprise connecting portion 310 and width slipping part 311 greater than this connecting portion 310, described connecting portion 310 passes described insertion mouth 110 and is contained in the described accepting groove 11, described slipping part 311 passes described support slot 13 and slides along described guide channel 12 under external force, drives connecting portion 310 simultaneously together along same linear slide; As shown in Figure 4, the front end face of described elastomer 32 is butted on the front end face of described accepting groove 11, and end face is connected to the front end face of described slipping part 311 thereafter; Described actuator 33 comprises a circular articulated section 330, and the forced section 3300 that extends to form of the outer bending of these articulated section 330 1 side direction and from force section 3301 that opposite side extends to form certainly, wherein, described articulated section 330 is articulated on the described drive-connecting shaft 15, institute's pivot forced section 3300 contacts with the rear end face of described slipping part 311, and slide along described slideway 16, the lateral margin horizontal-extending of described force section 3301 from described articulated section 330 forms a horizontal part 33010, lateral margin bending downwards from this horizontal part 33010 extends to form a vertical component effect 33011 again, its cross section is curved, after described forced section 3300 is subjected to thrust from action bars 31, power is passed to this vertical component effect 33011, and this vertical component effect 33011 is about to electronic cards and withdraws from from connector.

Described lid 4 be provided with one with the described drive-connecting shaft 15 corresponding holding parts that cooperate 41, and a side of this holding part 41 extends to form two first button pin 411 certainly, extend to form one second button pin 412, the first button pin 411 and 412 actings in conjunction of the second button pin from opposite side and prevent that lid 4 from swinging all around.

Fig. 5 is not when inserting electronic cards, the position of trip mechanism 3, electronic cards is pushed in the process of connector, electronic cards promotes described vertical component effect 33011, make actuator 33 rotate, driving action bars 31 simultaneously slides, under the effect that clips of the front end face of described slipping part 311 and accepting groove 11 front end faces, described elastomer 32 produces strain, stored the energy that electronic cards is withdrawed from, because the bounce that produces behind the pressurized of stiction between described slideway 16 and the described forced section 3300, at electronic cards insertion connector and remove under the situation of external force greater than elastomer 32, described actuator 33 can not turn round, the energy of described elastomer 32 does not obtain discharging, like this, and when electronic cards is withdrawed from, only need apply less power, just can electronic cards be withdrawed from connector by the bounce of elastomer 32.
