The engaging device 11 includes two engaging arms 110 integrally provided on the left and right sides of the connector body 10 , and protruding buckles 111 are provided at the ends for engaging the card ejecting mechanism 12 .

The card ejection mechanism 12 includes a fixed plate 121, a guide seat 122, an ejector plate 123 and a push rod 124, wherein the fixed plate 121 is generally U-shaped, and its left and right ends are provided with square buttonholes 1214 and cards 1215 for They are engaged with the buckle 111 of the connector body 10 and the slot 1225 of the guide seat 122 respectively. The central plate partially covers the connector body 10 , and a clamping piece 1211 with proper elasticity is punched out in the center, and the clamping piece 1211 can clamp the ejector plate 123 . An arc guide groove 1212, 1213 is provided on both sides of the clip 1211, which can be used to guide the displacement of the ejector plate 123, and a guide port 1216 is provided on one side to provide a space for the ejector plate 123 to push. And this guide seat 122 is arranged on the both sides of connector body 10 separately, and one end 1221 is provided with slot 1225 as mentioned above for the card 1215 ferrules on both sides of U-shaped fixing plate 121, and the other end is provided with screw hole 1222, can Locked on the connector, a guide groove 1223 is provided on its inner edge to guide the insertion of the electronic card. In addition, a grounding reed 1224 is provided near the end of the guide slot 1223 to form a grounding loop with the inserted electronic card to suppress the interference of messy signals. The ejector plate 123 is a rectangular plate, which is placed flat on the connector body 10. It has a push end 1231 and a drive end 1232, wherein the push end 1231 is bent toward the electronic card insertion direction to form a push surface of 190 degrees. , can push and guide the electronic card, and the opposite side of the push surface is an inclined surface, which serves as a guide for the ejection plate 123 when it rotates. The driving end 1232 can be inserted into the socket 1241 of the push rod 124 . In addition, a first guide shaft 1233 is provided near the push-in end 1231 on the ejector plate 123, and a second guide shaft 1234 is provided at a place away from the push-in end 1231, and the two guide shafts 1233, 1234 correspond to the fixed plate respectively. The arc-shaped guide grooves 1212, 1213 of 121 can slide in the arc-shaped guide grooves 1212, 1213. In addition, there are adjustable movable fulcrums 15, 15' near the push end 1231 and the driving end 1232 respectively, including a shaft 151, 151' and a chute 152, 152', wherein the bottom edges of the shafts 151, 151' extend There are sliding seats 153, 153', which can be inserted into the sliding grooves 152, 152' to adjust the position. The supporting shaft 151 is the first supporting point for implementing the new card ejection operation, and the supporting shaft 151' is the second supporting point. When acting on the first fulcrum 151, the distance from the pushing end 1231 to the fulcrum 151 (resistance arm R1) is smaller than the distance from the driving end 1232 to the fulcrum 151 (force arm F1), so it is a labor-saving state when operating on the first fulcrum (as shown in Figure 5A). And when acting with the second fulcrum 151', the distance from the pushing end 1231 to the fulcrum 151' (the resistance arm R2) is greater than the distance from the driving end 1232 to the fulcrum 151' (the force arm F2), so the second fulcrum operates When pushing the leading end, the pushing stroke is larger than that of the first fulcrum. With the help of the adjustable movable fulcrums 15, 15', the force arm ratio between the pushing end 1231 and the driving end 1232 can be adjusted, so that the ejection stroke of the pushing electronic card can be adjusted. And the push rod 124 is arranged in the guide groove 1223 of the guide seat 122, and the fork 1241 provided at one end thereof is connected with the driving end 1232 of the ejector plate 123, and the other end is the force application end.

When the utility model is assembled, as shown in Figure 1, the connector body 10 is fastened in the button hole 1213 of the fixed plate 121 with the convex buckle 111 in turn, and then the left and right guide seats 122 are inserted into the two sides of the U-shaped fixed plate 121, using The card 1214 is connected and fixed with the plug-in card of the slot 1225, and finally the push rod 124 is put through the socket 1226 of the left guide seat 122, and the fork 1241 is forked on the driving end 1232 of the ejector plate 123, so that the ejector plate The pushing end 1231 of 123 is located in the guide opening 1216 of the fixing plate 121, and the assembly can be completed (as shown in FIG. 4 ).

After the combination is completed, adjust the fulcrum 151, 151' to an appropriate position as needed. The principle of adjustment is that when the fulcrum 151 is used as the fulcrum, the closer it is to the pushing end 1231, the more labor-saving it will be. And when the fulcrum 151' is used as the fulcrum, the closer to the driving end 1232, the larger the stroke of the pushing end 1231 is, that is, when the distance of the electronic card being pushed is longer, the distance for the fulcrum 151 is larger. 'needs to be closer to the driving end 1232 for adjustment, and vice versa. Referring to Figures 5A, 5B, and 5C, the action schematic diagrams of the electronic card connector of the present invention when the card is withdrawn show the sliding state of the ejector plate 123 on the fixed plate 121 and the arc on the connector body 10. The relationship between the movement of the fulcrum of the shaped support plate 125 is for the sake of clarity of the drawing, and the components that are not related to the action of pushing out the electronic card are not shown in the figure. Referring to Fig. 5A, when the electronic card (not shown) is inserted and positioned, the pushing end 1231 of the ejector plate 123 is pressed against the bottom end of the connector body 10 by the electronic card, while the driving end 1232 is located away from the connector body 10 , the side of the pushing end 1231 of the ejector plate 123 abuts against the supporting shaft 151 . When the card is withdrawn, press the push rod (not shown) to make the driving end 1232 shift to the bottom end of the connector body 10. At this time, the fulcrum 151 is used as the fulcrum and the guide shaft 1233 is a sliding guide shaft. For the end 1231, because the moment from the driving end 1232 to the fulcrum 151 is longer (that is, the force arm F1 is long), and the moment from the pushing end 1231 to the fulcrum 151 is shorter (that is, the resistance arm R1 is short), therefore The electronic card plugged into the connector body 10 can be pushed out with less effort. Please refer to FIG. 5B , the electronic card is not completely pushed out (not shown) after being ejected, but is only in a state of disengaging from the connector body 10 , and the exerting force arm and the resisting force arm are approximately equal in length. If you continue to press the push rod (not shown), the guide shaft 1234 will be used as the sliding guide shaft, and referring to Fig. The leading end 1231 moves away from the connector body 10. At this time, because the electronic card is in a loose state (it has been detached from the connector body), even if the force distance from the driving end 1232 to the support shaft 151' is relatively short ( That is, the applying force arm F2 is short), but it is also very labor-saving in pushing and pulling, and relatively longer than the resisting force arm R2, the electronic card can be completely pushed out.

Therefore, the card ejection mechanism of the electronic card connector of the present utility model adopts a two-stage segmental type ejection card, and sets the required distance of pushing out the electronic card through two adjustable fulcrums, and then through the force arm and the force arm during the card ejection operation process. To change the resistance arm, the electronic card plugged on the connector body is ejected to a disengaged state in a labor-saving manner with a longer force application arm. Then push and guide the electronic card with a larger displacement stroke with a longer resistance arm, and push the electronic card out of the plugged electronic card in a labor-saving manner but with a larger push-out stroke.
