Page 9 M275598 IV. Creation instructions (5) The buckle arm 4 2 is formed by bending a rod-shaped wire, which includes a retaining end (not labeled) fixed in the retaining groove 43 and a protruding protrusion 4 〇 side is exposed to the locking portion 45 in the trough space 14 and the end 46 opposite to the locking portion 45. The locking portion 45 can cooperate with the notch 81 formed on one side of the electronic card 80 so that the electronic card 80 and the slider 40 can slide together in the insertion and withdrawal directions of the electronic card 80. A slot 47 is formed on the bottom of the slider 40 on the outer side of the locking arm 42 to allow the locking arm 42 to elastically deflect to the outside to avoid being damaged when the electronic card 80 is inserted. Please refer to the third to fifth figures. The bottom wall 11 of the insulating body 10 is formed with a card slot 丨 1 between the stepped surface 1 1 〇 on the right side and the adjacent side wall 丨 2 for receiving the withdrawal. Card agency. The side wall 12 adjacent to the slot 1 1 1 is provided with a convex rib 123, and the rear wall 13 corresponds to the slot 111 to form a cylinder 131 protruding forward perpendicular to the rear wall 13. The card slot ill penetrates through the rear wall 13 near the rear end of the rear wall 13 to form a through hole 11 2, and a front end is further provided with a support block 11 3 ′ that strikes the left and right sides of the bottom wall 11 and the adjacent side wall 12. Each one extends backward a live broadcast wall 114. The stopper 113 includes a hexagonal cavity 115 penetrating forwardly therethrough and a circular cavity 116 penetrating backwardly and completely communicating with the hexagonal cavity 115. The cross-sectional size of the circular cavity 11 6 is smaller than the cross-sectional size of the hexagonal cavity 1 1 5, and the circular cavity 1 16 further extends backward to form an arc-shaped cross-section on the two vertical retaining walls 丨 4 Through the two vertical blocking walls 114. Referring to the sixth figure, the insulating body 10 penetrates the bottom wall 11 in a hexagonal cavity 1 1 5 near the circular cavity 1 16 to form all the holes 117 downward. In addition, a plurality of bumps 11 8 are formed on the bottom surface of the insulating body 10. The bumps 11 8 include linear bumps 11 8 provided along the leading edge of the insulating body 10, and a plurality of bumps 11 8 are provided at each turn.

M275598 IV. Creation Instructions (6) Corner bumps 1 1 8 and plural rectangular bumps 1 1 8. Please continue to refer to the fifth figure. When assembling the card ejection mechanism, the slider 40 is placed in the slot 111, and the rib 123 of the insulating body 10 is located in the slot 47 at the bottom of the slider 4. The first spring 6 〇 Set on the cylinder 131, the other end is placed in the hole (not labeled) of the slider 40; the second spring 70 is inserted from the hexagonal cavity ιΐ5 = the circular cavity 116, and then the metal sheet 71 is passed through the cutout 117 is inserted into the insulating body 10, and the second spring 70 is reliably fixed in the circular cavity 116 by the restriction of the two vertical retaining walls 114 and the metal sheet. One end of the guide 50 is fixed to the supporting block. Inside the small hole 119 on 112, the other end is slidably arranged in the heart-shaped guide groove of the slider 40. When the metal shell 30 is assembled on the insulating body 10, the bean elastic arm 34 can press the guide 5 () downward to prevent the guide 5 () from popping out of the heart-shaped guide groove, and the stopper piece 35 abuts against the slider A side wall of 40 plays a certain limiting role. When the electronic card 80 is inserted, it is electrically connected to the terminal 20 by means of the guide = space 14 of the two stepped surfaces 110 on the bottom wall 11. In Ι! Ι, the locking arm 42 will slide into the notch of the electronic card J: split = into the recessed part 82 of the front end of the electronic card 8 ° against the second card '41 of the slider, and the lunar block 40 is driven together Moving backward, it slides in the heart-shaped guide groove and the first spring 60 is compressed. When the electronic card 801 is inserted and inserted, the guide 50 cooperates with the heart-shaped guide groove to set the slider M and the electronic card ，. At this time, the convex rib 123 can restrict the locking portion of the locking arm 42. Flash lock device, and then push down the electronic card, the electronic card 80 can be ejected. With the card; two degrees: the resilience effect, positioning Jinribei, 筮-遝 益 7Π bamboo card is over%, when the slider 40 slides To # 一 弹 通 0 will touch the independent wall 44 of the slider 40, and M275598 IV. Creation instructions (7) Generate a spring force that prevents the slider 40 from further sliding, so that the structure can prevent rapid withdrawal of the card and cause the electronic card 8 〇 Flying out. During the entire insertion and withdrawal process of the electronic card 80, its bottom surface only slips on the step surface 11 of the bottom wall 11. The contact area between them is relative to the electronic card 80 on the entire bottom wall 1 The sliding on the top 1 is much smaller, so the electronic card 80 has less friction when sliding, and it can be easily inserted into the storage space 1 4. The bottom soil 1 1 can choose the electronic card 8 0, That is to say, the structure of the connector of the electronic card is relatively comprehensive. The author has indeed filed a patent application. However, the above methods do not In this way, the conversion or changes of those with ordinary knowledge in the field of innovation should be included in the attached requirements for new patents, and those who are disclosed according to law are only the scope of rights for the best implementation of this creation.
