FIG. 3B is a schematic top view of the ejector pin of the electronic card connector of FIG. 3A in a second position. Please refer to FIG. 2 , FIG. 3A and FIG. 3B , in this embodiment, the electronic card connector 100 includes a housing 110 , a tray 120 , an ejection mechanism 130 , a ejector rod 140 and a positioning member 150 . In order to make the drawing clearer, FIG. 2 omits to show the tray 120 in FIG. 3A and FIG. 3B . Specifically, the housing 110 has an opening 112 . The opening 112 corresponds to the opening 52a of the cabinet 52 of FIG. 1 . The tray 120 corresponds to the housing 110 and is adapted to enter the housing 110 through the opening 112 or exit the housing 110 through the opening 112 , as shown in FIGS. 3A and 3B . The tray 120 has two accommodating slots 122 (shown in FIG. 3B ) for carrying two electronic cards (not shown) respectively. Therefore, the electronic card is moved into the casing 110 through the tray 120 to be electrically connected with the circuit carrier 54 , or moved out of the casing 110 through the tray 120 . In addition, the ejection mechanism 130 is disposed in the casing 110 for pushing the ejection tray 120 away from the casing 110 . Furthermore, the ejection mechanism 130 of this embodiment is pivotally disposed on the housing 110 and adapted to rotate relative to the housing 110 so as to eject the tray 120 through rotation. However, in other embodiments, the ejection mechanism 130 may also be other mechanisms suitable for ejecting the tray 120 from the housing 110 , and the present invention does not limit the specific implementation of the ejection mechanism 130 . In addition, the ejector rod 140 is disposed on the housing 110 and coupled to the ejector mechanism 130 . Furthermore, the ejector rod 140 is adapted to move from the first position P1 to the second position P2 along the axial direction D, as shown in FIGS. .

Specifically, in this embodiment, the ejecting mechanism 130 has opposite first end 132 and second end 134 , wherein the first end 132 corresponds to the tray 120 , and the second end 134 corresponds to the ejector rod 140 . The ejection mechanism 130 is pivotally disposed on the casing 110 and is adapted to rotate relative to the casing 110 so that the first end 132 and the second end 134 thereof can move relatively. The tray 120 and the push rod 140 move relative to the casing 110 along two opposite directions of the axial direction D respectively. When the tray 120 is completely moved into the casing 110 along the axial direction D, the tray 120 pushes the first end 132 of the ejection mechanism 130, so that the ejection mechanism 130 rotates relative to the casing 110, and the ejection mechanism 130 rotates to The second end 134 pushes the push rod 140 to move out of the housing 110 along the axial direction D, and is located at the first position P1, as shown in FIG. 3A . Relatively, when the ejector rod 140 moves from the first position P1 to the second position P2 toward the housing 110 along the axial direction D, the ejector rod 140 pushes the second end 134 of the ejector mechanism 130 so that the ejector mechanism 130 is relatively When the casing 110 rotates, the ejection mechanism 130 pushes the tray 120 to move out of the casing 110 along the axial direction D through the rotation of the first end 132 , as shown in FIG. 3B . When the tray 120 is completely moved into the casing 110 along the axial direction D again, the tray 120 pushes the first end 132 of the ejection mechanism 130 again, so that the ejection mechanism 130 rotates relative to the casing 110, and the ejection mechanism 130 The second end 134 pushes the ejector rod 140 to move out of the casing 110 along the axial direction D to the first position P1 for the next time the tray 120 is withdrawn from the casing 110 . It can be seen that, in the electronic card connector 100 of this embodiment, the tray 120 can be moved out of the housing 110 and the electronic card can be ejected only by pushing the push rod 140 toward the housing 110 along the axial direction D. Accordingly, the electronic card connector 100 of this embodiment is suitable for connecting two electronic cards, and has a simple way of withdrawing the cards.

4A and 4B are partially enlarged schematic views of the electronic card connector shown in FIG. 3A and FIG. 3B . Please refer to FIG. 3A to FIG. 4B , in the present embodiment, the positioning member 150 is disposed in the casing 110 and located between the push rod 140 and the tray 120 . The positioning member 150 is, for example, an elastic elastic piece, wherein one end of the positioning member 150 is fixed to the housing 110 , and the other end is located at a side of the tray 120 . The ejector rod 140 is suitable for interfering with the positioning member 150 during a moving stroke between the first position P1 and the second position P2, so as to exert a lateral force on the tray 120 through the positioning member 150 . Specifically, the side of the tray 120 in this embodiment has a positioning groove 124 , and the positioning member 150 has a first abutting portion 152 and a second abutting portion 154 . The first abutting portion 152 faces the push rod 140 , and the second abutting portion 154 faces the positioning groove 124 on the side of the tray 120 . In addition, the push rod 140 in this embodiment has a pushing portion 142 facing the positioning member 150 . The above-mentioned first abutting portion 152 and second abutting portion 154 are, for example, protrusions formed by bending the positioning member 150 , while the pushing portion 142 is, for example, a protrusion formed by bending the push rod 140 . When the tray 120 is gradually moved into the housing 110, the ejector rod 140 is pushed by the ejection mechanism 130 to gradually move out of the housing 110, and the pushing portion 142 of the ejector rod 140 is adapted to the first abutting portion of the positioning member 150. 152 forms an interference to exert a lateral force on the tray 120 through the second abutting portion 154 of the positioning member 150 . In other words, when the push rod 140 gradually moves out of the casing 110 along the axial direction D to the first position P1, the pushing portion 142 of the push rod 140 moves out of the casing 110 along with the push rod 140 , and then contacts with the first position of the positioning member 150 . An abutting portion 152 forms interference. At this time, the pushing portion 142 of the push rod 140 pushes the first abutting portion 152 of the positioning member 150 toward the side of the tray 120, so that the second abutting portion 154 of the positioning member 150 also moves toward the direction of the tray 120, thereby The tray 120 exerts a lateral force, as shown in FIGS. 3A and 4A . When the tray 120 is completely moved into the casing 110 and the ejector rod 140 is at the first position, the above-mentioned lateral force reaches the maximum value, and the second abutting portion 154 of the positioning member 150 can fit into the positioning groove 124 of the tray 120 Inside. It can be seen that when the tray 120 is completely positioned in the casing 110, the tray 120 can be positioned by the positioning member 150, and can be firmly positioned in the casing by the above-mentioned lateral force and the second abutting portion 154 fitting into the positioning groove 124. body 110 , so that the unshown electronic card disposed on the tray 120 can be stably connected to the circuit carrier 54 without being shaken and causing poor contact. Accordingly, the electronic card connector 100 of this embodiment has good operational stability.

In contrast, when the ejector rod 140 moves from the first position P1 to the second position P2 along the axial direction D, and the ejector mechanism 130 pushes the tray 120 to move out of the housing 110 , the pushing portion 142 of the ejector rod 140 moves along with the ejector mechanism 130 . The rod 140 moves into the housing 110 to release the interference with the first abutting portion 152 of the positioning member 150 . At this time, the positioning part 150 is reset by its elasticity, and the first abutting part 152 and the second abutting part 154 move away from the tray 120 to gradually reduce the above-mentioned lateral force until the second abutting part 154 moves out of the positioning position. The groove 124 does not touch the side of the tray 120, or until the second abutting portion 154 only slightly touches the side of the tray 120, without affecting the movement path of the tray 120 moving out of the housing 110 along the axial direction D, as shown in FIG. 3B and Figure 4B. Therefore, the configuration of the positioning member 150 can increase the operational stability of the electronic card connector 100 , and does not affect the ejection mechanism 130 driven by the ejector rod 140 to eject the tray 120 out of the housing 110 . However, in other unillustrated embodiments, the side of the tray 120 may also omit the configuration of the positioning groove 124, and be directly positioned in the housing 110 by the lateral force applied to the side by the positioning member 150. The invention is not limited to the above-mentioned embodiments.

Please refer to FIG. 3A and FIG. 3B again. In this embodiment, the electronic card connector 100 further includes a plurality of conductive terminals 160 . The conductive terminals 160 are disposed in the housing 110 and electrically connected to the circuit carrier 54 . In addition, each accommodating slot 122 of the tray 120 has an opening 122 a (shown in FIG. 3B ). When two electronic cards (not shown) are carried in the two accommodating slots 122 of the tray 120 respectively, the openings 122a are adapted to expose parts of the electronic cards, for example, the conductive pads on the electronic cards. Therefore, when the two electronic cards are respectively loaded on the two accommodating slots 122 of the tray 120, and the tray 120 is moved into the housing 110, the two electronic cards are moved into the housing 110 through the tray 120, and are respectively connected to the conductive terminals 160 through the opening 122a. electrical connection. On the other hand, in this embodiment, the electronic card connector 100 further includes a switch 170 . The switch 170 is disposed in the casing 110 and electrically connected to the circuit board 54 . When the tray 120 is fully moved into the housing 110 , the tray 120 triggers the switch 170 to make the switch 170 electrically connect the electronic card connector 100 and the circuit carrier 54 . Relatively, when the tray 120 moves out of the housing 110 , the switch 170 cuts off the electrical connection between the electronic card connector 100 and the circuit carrier 54 . The manner in which the tray 120 triggers the switch 170 is, for example, that the tray 120 overlaps the switch 170 so that the switch 170 senses the position of the tray 120 , but the present invention is not limited to the above embodiments.

FIG. 5 is a side view of the electronic card connector of FIG. 2 . Please refer to FIG. 2 and FIG. 5 , in this embodiment, the bottom surface S1 of the housing 110 of the electronic card connector 100 has a first positioning structure 114 , and the bottom surface of the tray 120 has a second positioning structure (not shown). When the tray 120 moves into the casing 110, the first positioning structure 114 cooperates with the second positioning structure. Accordingly, the tray 120 can be prevented from being moved into the casing 110 in a wrong direction. In addition, in this embodiment, the top surface S2 of the housing 110 has a connecting portion 116 , wherein the top surface S2 is opposite to the bottom surface S1 . The connecting portion 116 extends from the top surface S2 toward the bottom surface S1 , and is connected to the circuit carrier 54 to fix the housing 110 on the circuit carrier 54 . Accordingly, the flatness when the tray 120 is moved into the casing 110 can be increased.

To sum up, the tray of the electronic card connector of the present invention is suitable for carrying two electronic cards, wherein the ejection mechanism is used to push the tray away from the housing, and the ejector rod is disposed on the housing and coupled to the ejection mechanism. When the ejector rod moves from the first position toward the inside of the housing to the second position, the ejector rod can drive the ejection mechanism to push the tray out of the housing. In addition, the positioning element is located between the ejector rod and the pallet. The ejector rod is suitable for interfering with the positioning member during a movement stroke between the first position and the second position, so as to exert a lateral force on the tray through the positioning member. When the tray is completely moved into the casing and the ejector rod is at the first position, the lateral force reaches a maximum value to fix the tray in the casing. Accordingly, the electronic card connector and the electronic device of the present invention are suitable for connecting two electronic cards, and have a simple card return method and good operational stability.
