A plurality of card edge connectors can be provided on a printed circuit board that provides only limited functionality to receive printed circuit cards having different functions, thereby expanding the functions of the circuit boards. The card circuit card that is inserted into the cut connectors is detachable to smoothly exit the printed circuit cards, and the card ejecting mechanism is often used to exit the printed circuit cards. By way of example, in a computing system, a memory module is a printed circuit card that is well known to Daping. In order to exit the memory module, many retreat mechanisms have been developed. Traditionally, lever arms have often been used for card withdrawal. However, the lever arm is usually close to the main board, so it is not easy to operate 1 and the lever arm requires a large space to facilitate its rotation. Therefore, ' is not compatible with today's compact design. In order to solve the above-mentioned deficiencies, a number of card-removing institutions are proposed, for example, U.S. Patent No. 5,571,025 to Arai et al., U.S. Patent No. 5,577,922 to En. et al., and U.S. Patent No. 5 to Suzuki et al. 66〇, 552, etc. have related disclosures. Each of the foregoing patents discloses a similar ejecting machine, which includes a push rod and a rotating member, wherein the rotating member can be inserted into one of the push rod and the road card. The pusher transmits a force to the rotating member - the rotating member rotates. After the other end of the rotating rotating member contacts the insertion end of the printed circuit card 201108513, it is pushed until the printed circuit card is ejected. Typically, the inserted printed circuit card is clamped to prevent accidental movement. Moreover, the inserted printed circuit card usually needs to be moved a certain distance before it can be completely exited. Since λ ' is such that the inserted printed circuit card is completely withdrawn, the rotating member must be large enough to generate sufficient leverage to allow the card ejection operation to be smooth, and the rotating member must be rotated to a certain degree to enable the printed circuit card Move beyond one of the aforementioned distances. Therefore, the card edge connector needs to have a large

The support portion in further has a pair of rear bottom surfaces 1112, and each of the rear bottom surfaces 1112 and the top end surface of the corresponding end wall 1213 of the end portion 121 are disposed correspondingly and can abut each other. Each of the pushers is supported by a front bottom surface 11u and a rear bottom surface 1112. It is possible to avoid exceeding the lowest position when moving down, and to avoid tipping in or out when the top button member 13 is in the open position. Referring to FIG. 8 , FIG. 9 and FIG. 10 , the two positioning rods 113 extend from one side of the front bottom surface 1111 of the support portion m, and a pushing portion 114 is disposed between the two positioning rods 113 , wherein The pushing portion 114 has an end surface 1141 that is configured to abut against the end portion 1342 of the arm portion 134. Accordingly, as shown in Fig. 8, a rod receiving groove 12112 is formed on the inner side surface of each side wall 1211 of the end portion i2i to guide the corresponding positioning rod 113. On the bottom surface of the rod receiving groove 12112, a concave section 12113 is formed. Each of the positioning rods 113 includes a side projection 1131, and the side projections 1131 protrude laterally and are disposed corresponding to the concave portion 12U3. Referring to FIG. U, when the pusher u is mounted on the end portion i2i, the side bumps 1131 enter the corresponding concave sections 12113, and the pusher 11 is restricted to extend only vertically from the concave section 12113. Move within the range. Referring to Figs. 8 and 10, on the inner side surface of the end wall 1213 of each end portion 121, three parallel elongated grooves 12131 are formed in the moving direction of the pusher U. Accordingly, an elongate projection member 112 and two side lug members 1132 are formed on the pusher member 11. The projecting member 112 is movable within an intermediate elongated slot 12131 formed in the side of the push portion 114 that faces the end wall 1213. The two side protrusions 1132 are respectively protruded from the corresponding positioning rods ι 3, and the two side protrusions 1132 are disposed corresponding to the two sides of the elongated slots J 2丨3丨, and can be respectively disposed on the two sides of the elongated slots 1213 1 Move inside. The combination of the projecting member 丨丨2 and the intermediate elongated slot 12131, and the combination of the tab members 1132 on both sides and the elongated slots 12131 on both sides guide the movement of the pusher u. Furthermore, the engagement of the projecting member η with the intermediate elongated slot 12131 prevents the pushers u from being mounted in an incorrect combination orientation. -12· 201108513 Referring to FIG. 12 and FIG. 13 , each pusher member further includes a body portion 115 and a head end portion 116, wherein the head end portion 116 is supported by the body portion 115, and is constructed to be A user's finger or thumb is pressed. The body portion US can have an elongated shape to thereby encourage airflow through the body portion 115 to enhance heat dissipation into the printed circuit card 3. A long slit 17 is provided along the inner side of the body portion 丨15. The slit 1 is constructed so that the corresponding side portion of the printed circuit card 3 can be slipped therein to guide the printed circuit card 3 when it is mounted. The head end portion 116 can have a beveled surface 1161 that faces and slightly faces away from the card edge connector 丨 so that when the printed circuit card 3 is being ejected, the pusher 丨丨 can still be pushed toward the card edge connector 1.
