Definitions

• the present invention relates to a card-ejection mechanism for a card socket, and more
• a card-ejection mechanism comprises: a sliding rail, having a protruding part, a push-end position, and a push-out position; an ejector, mounted on the sliding rail and slideable between the push-end position and the push-out position of the sliding rail for ejecting a card; and a spring, for linking the ejector and providing an ejection spring force, wherein, when the ejector is pushed from the push-out position to the push-end position of the sliding rail, the ejector is hooked on the protruding part and thereby stretches the spring to generate an ejection spring force, and when the ejector is pushed again, the ejector is unhooked from the protruding part, and then slides back to the push- out position

• the card connector 1 includes a housing 10 and a card-ejection mechanism 20.
• the present invention more particularly relates to a card- ejection mechanism 20, wherein the card-ejection mechanism 20 comprises a sliding rail 201, an ejector 202, and a spring 203.
• the sliding rail 201 has a protruding part 208, a push-end position 206, and a push-out position 207.
• Fig. 1 is schematic views of a card-ejection mechanism applied in a card connector according to a preferred embodiment of the present invention.
• the card connector 1 includes a housing 10 and a card-ejection mechanism 20.
• the present invention more particularly relates to a card- ejection mechanism 20, wherein the card-ejection mechanism 20 comprises a sliding rail 201, an ejector 202, and a spring 203.
• the ejector 202 can be mounted on the sliding rail 201 and slideable between the push-end position 206 and the push-out position 207 of the sliding rail 201, for ejecting a card (not shown).
• the spring 203 is connected between the sliding rail 201 and a rod 204, and provides an ejection spring force.
• the ejector 202 When the ejector 202 is pushed from the push-out position 207 to the push-end position 206 of the sliding rail 201, the ejector 202 is hooked on the protruding part 208 and thereby stretches the spring 203 to generate an ejection spring force, and when the ejector 202 is pushed again, the ejector 202 is unhooked from the protruding part 208, and then slides back to the push-out position 207 and ejects the inserted card by the ejection spring force.
• the housing 10 includes a bottom side 102 and a top cover 101 for accommodating a card.
• the card connector 1 is usually installed in the computer or system host computer (not shown), and coupled with a socket, and thereby can be linked with the computer or system host computer when a card is inserted into the card connector 1.
• the bottom side 102 and top cover 101 of the housing 10 shown in Fig. Ia are made of metal material or other materials. Also as shown in Fig.lb, the housing has only a single side. Several holes are on the bottom side 102 and top cover 101 for sinking heat.
• the housing 10 has an inner wall 103 defining a groove for the insertion of a card.
• the card connector 1 further comprises a guiding plate 30 for guiding a card to ensure that the card is properly inserted in the card connector 1.
• Fig. 2a is a schematic view of the card-ejection mechanism according to the preferred embodiment of the present invention.
• Fig. 2b is an exploded view of the component parts of the card-ejection mechanism 20.
• the ejector 202 is mounted on the sliding rail 201, and is slideable between two ends of the sliding rail 201.
• One end of the spring 203 is hooked on the ejector 202, and the other end of the spring 203 is connected to the housing 10 or the sliding rail 201 by a rod. Therefore, when the card is inserted in the housing 10 and pushed inwards along the inner wall 103 of the groove, the card pushes the connection rod 2022 of the ejector 202. Then, the ejector 202 is dragged and slides on the sliding rail 201 and thereby stretches the spring 203.
• the sliding rail 201 has a protruding part 208, a push-end position 206, and a push-out position 207.
• a groove 2081 is formed around the protruding part 208.
• the front end of the groove 2081 is V-shaped, or on the whole, roughly heart-shaped.
• the rod 204 shown in Fig. 2b has a first end 2041 coupled with a hole 2023 of the ejector 202 and a second end 2042 bent to be hook-shaped.
• the spring band 205 is used to press the rod 204, such that the second end 2042 can be forced against the sliding rail 201 for ensuring that the second end 2042 of the rod 204 remains in the groove 2081.
• the first end 2041 of the rod 204 extends through the hole 2023 of the ejector 202.
• the position of the hole 2023 in the ejector 202 is shown in Fig. 2b, and it is better that it deviates from the central line 2021 of the ejector 202, to ensure that the second end 2042 moves circularly around the protruding part 208 in the groove 2081.
• Fig. 4 is a partial enlarged view of the card connector according to the preferred embodiment of the present invention, for further illustrating the card-ejection mechanism of the present invention.
• the connection rod 2022 of the ejector 202 is pushed by the card, such that the ejector 202 slides on the sliding rail 201.
• the rod 204 is pushed from the push-out position 207 to the push-end position 206 in the groove 2081. Then, the rod 204 slides into the V-shaped front end of the groove 2081.
• the ejector 202 As the rod 204 is hooked on the V-shaped front end of the groove 2081, the ejector 202 is fixed at the rear end of the sliding rail 201.
• the rod 204 When the second end 2042 of the rod 204 is pushed away from the V-shaped front end of the groove 2081, the rod 204 returns back to the push-out position 207 in the groove 2081 in the direction shown in Fig. 4 by the restoring force of the spring 203.
• the ejector 202 also pushes out the inserted card due to the restoring force of the spring 203.
• the second end 2042 of the rod 204 can move circularly in the groove 2081.
• cards can be displaced to the insert position or the remove position repeatedly via a single push action.
• the card-ejection mechanism described in the present invention is not limited to application in the card connector described in the embodiment, but can be applied in other embodiments.
