The electronic card connector 1 is a double-layer type, and the upper and lower layers have the same structure and are stacked on each other. , a plurality of conductive terminals 13, a sub-circuit board 14, a card ejection mechanism 15, and a positioning guide device 16, wherein the positioning guide device 16 is shown in FIG. The ground metal plate 12 shields the insulating base 10 to provide electromagnetic shielding. The sub-circuit board 14 has gold fingers that are plugged and welded with each conductive terminal 13 . This card ejecting mechanism 15 is a kind of driving mechanism, and its guide rod base 151 is connected on both sides of this insulating seat body 10, and ejection plate, rocking bar, push rod and positioning plate are all positioned at this grounding metal plate 12 below (not shown in the figure). Shown, can refer to the Taiwan patent application No. 83202198 of the applicant of the present invention), wherein the difference between the card ejecting mechanism 15 and the existing device is the push rod, please refer to Fig. 3B, the push rod 154 is divided into two sections, front and rear, The front section is an elongated plate body 1541 of metal material, and its end edge is provided with a set of openings 15410 for one end of the ejector plate 152 to be nested; the rear section is an elongated rod body 1542, which has a shaft hole 15421 and a socket 15422, The front edge is provided with a concave hole 15423, the rear edge is a push-in end, and a recess 15424 is provided on one side, which can cooperate with the protrusion 1513 of the guide rod seat 151, but its length is far longer than that of the protrusion 1513. It is to limit the maximum distance before and after the card ejection mechanism 15 operates. The front elongated plate body 1541 and the rear elongated rod body 1542 are juxtaposed in the groove 1511 of the guide rod seat 151, and the front elongated plate body 1541 is pushed indirectly by the axial movement of the rear elongated rod body 1542. Guide the ejection plate 152 to make the ejection plate 152 eject the electronic card for operation, which will be described in detail later in conjunction with the positioning guide device 16 .

The positioning guiding device 16 is arranged on the guide rod seat 151 on one side of the card ejecting mechanism 15, please refer to FIG. A pressure spring 163 and a cover plate 164, wherein the guide groove 160 is located on a concave surface outside the guide rod seat 151, which is an open ring groove body, please refer to Figure 4A, 4B, the guide groove There are four positioning steps 1601 , 1602 , 1603 , 1604 inside 160 , and inclined surfaces 1605 are provided between the first positioning step 1601 and the third positioning step 1603 and between the third positioning step 1603 and the fourth positioning step 1604 . The first positioning step 1601 is used to prevent the sliding block 161 (refer to FIG. 3B ) from slipping backward; the second positioning step 1602 is used for positioning when the card is inserted or not; the third positioning step 1603 is used for the positioning of returning the card ; The fourth positioning step 1604 is located between the second positioning step 1602 and the third positioning step 1603, and is used to prevent reverse sliding to the second positioning step 1602. Referring to Fig. 3B, one end of the slider 161 has a pivot hole 1610, through which a pivot 166 penetrates and is pivotally mounted on the shaft hole 15421 on the push rod 154, and the other end has a shaft 1611, which can be used in the guide sliding in slot 160. The elastic element 162 is a compression spring, which is sleeved on the positioning rod 1512 in the groove 1511 of the guide rod seat 151, one end of which is received in the concave hole 15423 on the end edge of the elongated rod body 1542, and the other end is against the guide rod 1542. The inner wall of the groove 1511 of the rod seat 151 can provide the restoring force after the push rod 154 slides. One end of the pressing reed 163 is a U-shaped body 1631 , which is embedded in the slot 15422 on the push rod 154 , while the other end is a long strip body 1632 , whose end edge is slightly bent against the surface of the slider 161 , so that the slider 161 is more stable when sliding. The cover plate 164 is covered on the groove 1511 of the guide rod base 151, and its left and right are provided with embedding lugs 1641, 1642, which can be embedded into the button body (not shown) on the guide rod base 151 to accommodate Components within the groove 1511 are fixed.

Please refer to FIGS. 5A, 5B, 5C and 5D, which are schematic diagrams of the operation of the push rod 154 and the positioning guide device 16 (only the side of the electronic card connector with the push rod 154 is shown in the figure), wherein FIG. 5A is a plug-in card Or the state of not inserting the card, at this moment, the end of the rear section elongated rod body 1542 of the push rod 154 is positioned at the inside of the casing 9 (a wall surface is simply shown in the figure) of the portable computer, and the fulcrum 1611 of the slide block 161 is positioned at the first On the second positioning step 1602, the compression spring 162 is in a state of being compressed and storing energy. In this state, the top end 1612 of the slider 161 is introduced into the central direction of the guide rod seat 151, never interfering with the movement of the front elongated plate 1541 of the push rod 154, so the front elongated plate 1541 of the push rod 154 can Free axial sliding without restriction, that is, the connector may or may not be inserted into the electronic card in this state. And when wanting to withdraw the card after inserting the card, as shown in Figure 5B, must first push forward the elongated rod body 1542 of the back section, make the supporting shaft 1611 break away from the second positioning step 1602 (at this time, the elongated rod body 1542 will be slightly protruded 9), and because the elongated rod body 1542 has the setting of the fourth positioning step 1604 during the pushing process, please refer to Figure 4B. It will slide backwards to the second positioning step 1602, and must fall into the fourth positioning step 1604, and slide along the slope 1605 to the third positioning step 1603, that is, from FIG. 5C to FIG. 5D. At this time, the end of the elongated rod body 1542 protrudes from the outer casing 9, so that the card can be easily pressed out of the outer casing 9, and the end of the upper elongated rod body 1542 in FIG. 3A is in a protruding state. And when pressing back card, because this slide block 161 is positioned at the side of fulcrum 1611, and is positioned at the rear end of elongated plate body 1541 of front section, after pressing elongate rod body 1542, the fulcrum 1611 of this slide block 161 moves along The inclined surface 1605 slides toward the first positioning step 1601 (as shown in FIG. 6A ). At this time, the top 1612 of the slider 161 pushes the front elongated plate body 1541 to slide forward, and the ejection plate 151 is operated to eject the electronic card. When continuing to push and guide the supporting shaft 1611 to the first positioning step 1601, the top 1612 of the slider 161 is guided by the guide groove 160 and gradually retracts into the center direction of the guide rod seat 151 until the supporting shaft 1611 is locked on the The second positioning step 1602 (as shown in Figure 5A), at this time the slider 161 as a whole is hidden under the elongated rod body 1542. During this process, due to the setting of the first positioning step 1601, the support shaft 1611 will not slip backwards .

It can be seen from the above description that the ejection operation of the present invention can be conveniently directly pressed from the outside of the computer case. Furthermore, since the front section and the rear section of the push rod are completely independent and separated, the operating distance between the two is not directly related, and due to the setting of the third positioning stage 1603, the distance that the rear section of the push rod protrudes can be greatly protruded from Outside the computer casing, it is convenient for users to operate. The operation of protruding the rear elongated rod body 1542 out of the computer casing before ejecting the card is also due to the setting of the first positioning step 1601 and the fourth positioning step 1604, which makes the overall operation smooth and convenient.
