1249277 IX. DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present invention relates generally to an electrical connector _1 5 relating to a memory card connector. BACKGROUND OF THE INVENTION Memory cards are conventional in the prior art and include information in the form of a memory circuit or other electronic program, and some type of card reader reads information or memory stored on the card 10. These cards are used in many applications in today's electronic society, including cameras, digital still cameras, smart phones, PDAs, music players, ATMs, cable TV decoders, toy 'games, PC connectors, multimedia. Cards and other electronic applications. Typically, a memory card includes a connector or terminal array for connecting to a card reader system via a card connector and then to an external device. The connector can be easily adapted to the insertion and withdrawal of the card to quickly obtain information and programs on the card, and the card connector includes a plurality of terminals for deformably coupling the connector array of the memory card. The memory card connector is often mounted on a printed circuit board, and the memory card itself can be read and written through the connector and can be transferred between electrical appliances such as word processors, personal computers, personal digital assistants and the like. . The card can be used in a variety of applications, such as mobile phones or cell phones, which can be actuated and allowed to enter after identifying a SIM (Subscriber Identity Module) card. The SIM card has a conductive surface to which a connector array 1249277 is attached, and the mobile phone has a SIM card having a plurality of terminals for electrically connecting the SIJV [card connector) to ensure the user identification. A typical memory card connector includes a 5-state insulating housing covered by a metal cover, and the metal cover can be forged from a sheet metal material and formed into a substantially box shape. The metal shroud, in conjunction with the housing, defines a card receiving recess ' and the recess is open to form a card insertion opening. The insulative housing may be generally L-shaped or U-shaped and includes a terminal ampoule section after the recess, and at least one of the recesses may extend forwardly from one or both ends of the rear section at one or both sides Longitudinal side wall section. The metal shroud has a top plate that substantially obscures the insulative housing, and a plurality of side panels extend downwardly on the outside of the side wall sections of the housing. One or both of the side panels of the metal shroud and/or the side wall segments of the housing define the sides of the card receiving recess. Examples of these connectors are disclosed in Japanese Patent Nos. 2002-3295 53 and 2002-343468. 15 Some card connectors include a card eject mechanism whereby the card can be inserted into the connector and the card eject mechanism can be used to assist in removing the card from the connector. Some eject mechanisms include a plurality of sliding members that incorporate the memory card and move in and out of the connector, and then the latches, cams, ejectors, and other operational components are operatively coupled to the slider rather than the memory The card itself. A card eject mechanism includes a heart shaped cam groove in the slider and a pin member is operatively biased into the heart cam groove and, under normal conditions, biases the slider with a spring member Exit the direction of the memory card. The card eject mechanism is referred to as a "push/push" "ejector' wherein the memory card is first pushed into the recess of the connector and reaches the operational position of a lock 1249277 buckle, and a pair of the card The second push effectively releases the card and allows the spring to eject the card from its latched position. Figures 18 and 19 show a conventional push/push memory card connector 70, and the connector includes a general An insulating housing is indicated at 72, and the insulating housing 72 is shielded by a metal housing substantially indicated at 74, and the metal housing 74 is coupled to the housing to form a card housing recess for receiving a memory card 76. A card eject mechanism, generally indicated at 78, is mounted to the housing and wherein the mechanism includes a cam slider 80, a cam pin 82, and a push/push of a spiral pop-up spring 84. The slider is along The longitudinal side wall 72 a of the housing moves between an initial position (Fig. 18) for receiving the 10 nanometer insulating housing 72 and an inner connecting position, and in the inner connecting position, most of the The 76a bond on the memory card is generally indicated at 86 and is mounted in the housing The terminal on the terminal mounting portion 72b. The cam slider 80 has a hook 88 detachably held in the recess 76b of the memory card 76, so that the memory card is in the outer initial position 15 together with the slider The metal housing 74 includes a top wall 74a and a side wall 74b. As shown in Fig. 19, the hook 88 is configured such that the rear side 90 faces the top wall 74a of the metal casing %. A bridge-like elastic piece 92 formed by the side wall 74b is provided, and the opposite ends of the elastic piece are not cut or connected to the side wall, and the elastic piece 92 2 is disposed on the rear side 90 of the hook 88. When the cam slider 8 is at its outer initial position, the slider can push the slider. When the memory card 76 is inserted into the card housing recess, the hook 88 is first pushed outwardly against the blade 92, and then the hook is buckled. The person has the recessed hole 76b of the memory card, and leaves a gap between the rear side 9〇 of the hook and the elastic piece. 94 〇7 1249277 This push/push type uses the spring member to bounce the card away from its latching position. There are many problems with other types of ejecting mechanisms. For example, to maintain the elastic force in the magazine structure must be difficult. If the pop-up spring is rather weak, it will be difficult and unsatisfactory to eject and remove the memory card. On the other hand, if the pop-up spring is too strong, the card and the sliding member will be quickly secreted in the pop-up direction, and in fact the card will eject the card connector and fall to the ground. Under the elastic force of the strong pop-up spring, the bridge-like elastic piece 92 of the conventional memory card connector 70 shown in Figs. 18 and 19 is insufficient to prevent the hook from being pulled out of the recessed hole 76b in the memory card. The present invention is intended to solve these problems by preventing the memory card from coming out of the connector even if a foot 10 is used to eject the memory card with a short and fast movement.

[Embodiment] 15 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in detail, and referring to FIG. 1A-2, the present invention is based on a memory card connector substantially indicated at 12 as an embodiment, and the memory The card connector 12 includes a metal housing, generally indicated at 14, and an insulative housing, generally indicated at 16, and the insulative housing 16 is mounted with a plurality of terminals that are generally indicated by 2〇18. A card eject mechanism, generally indicated at 20, is mounted within one side of the metal housing, and a card insertion guide, generally indicated at 22, is mounted in a front corner of the metal housing. A memory card, generally indicated at 24, can be inserted into the connector in the direction of the arrow "C". In detail, referring to Fig. 3 and Fig. 1A-2, the metal casing 14 is forged from 11 1249277 sheet metal material. The metal casing defines a card receiving recess generally indicated at 26 for receiving the memory card 24, and the metal casing includes a top or top wall 28 and a pair of substantially l-shaped side walls 30 extending downwardly along the top wall. With 32. The L-shaped side walls 30 and 32 together define opposite side edges of the recess 26, and the recess has a front insertion opening 34. As shown in Figures 1B and 2, the L-shaped side wall 3 has a vertical section 30a that is bent 90 degrees with respect to the top wall 28, and a horizontal bottom section 30b that is bent 9 degrees relative to the vertical section and extends inwardly therefrom. . A bottom guide 30 () is formed at the front end of the L-shaped side wall 30 to guide the memory card 24 into the recess 26. The L-shaped side wall 30 has a forged press-fit mounting flange 30d, and the mounting flange 3〇d protrudes forward to fix the metal case to a mounting pad of a printed circuit board by, for example, soldering. Finally, a window 30e is formed in the L-shaped side wall 30 and at its rear end. Similarly, the L-shaped side wall 32 includes a vertical wall section 32a that is bent 90 degrees along the edge of the top wall 28 15 of the metal casing, and a horizontal bottom section 32b is bent 90 degrees relative to the vertical section and extends inwardly therefrom. A mounting flange 32 () is forged from the side wall and can be mounted to the printed circuit board. An elongate guide 32d is forged from the horizontal bottom section 32b of the L-shaped side wall 32, and the guide rail projects upwardly from the horizontal section to guide the sliding member of the card ejecting mechanism 20 as follows. As shown in Fig. 2, a coupling flange 36 is bent in the rear direction of the metal casing, and the coupling flange has a coupling opening 36a and a mounting flange 36b for mounting to the printed circuit board. As shown in Fig. 3, a coupling flange 38 is bent forward in front of the metal casing and inside the side wall 32. Finally, an elastic leaf spring 40 is forged from the top wall 28 of the metal casing, 12 1249277 and immediately adjacent the inside of the L-shaped side wall 32. Referring to Figures 4 and 1A-3, the card insertion guide 22 is mounted inside the front end of the L-shaped side wall 32 of the metal casing 14 and at the side of the front insertion opening 34. A coupling flange 38 (Fig. 3) 5 which is downwardly defined by the top wall 28 of the metal casing is press-fitted into the latching hole 22a (Fig. 4) fitted in the top of the guide member, and the latching hole 22a is The plastic material is molded. A cam pin coupling hole 22b is also formed in the top of the guide member for the purpose described below. Finally, the guide member has an inward guide 22c that connects the bottom portion 32b of the side wall 32, whereby the memory card 24 can be introduced into the recess 10 by the guide 22c and the chamfered inner surface 22d of the card insertion guide 22. 26 in. Referring to Fig. 5 and Fig. 1A-2, the insulating case 16 is a one-piece structure molded of a plastic material or the like and has a long terminal block in which a plurality of terminals 18 are mounted. The terminals are mounted in a plurality of through holes 16a in the terminal block, and the terminals have a plurality of contact portions 18a that are overhanged into the recesses 26 to engage the appropriate connectors on the 15 memory card 24. The terminals have a plurality of tail portions 18b for connecting to appropriate circuit traces on the printed circuit board by, for example, soldering, and the tail portions 18b of the terminals are coplanar with the mounting flanges 30d, 32c and 36b of the metal housing. To solder to the board at the same time. The tweezers block has a coupling projection 16b at one end thereof for bonding into the window 30e of the side wall 2 of the metal casing, as shown in Fig. 2. The terminal block has a rear coupling projection 16c (Fig. 2) for coupling into the opening 36a of the metal flange of the coupling flange 36. Fig. 5 shows that the terminal block has an abutting wall 16d at one end thereof, and a spring holding projection 16e protrudes forward from the abutting wall. In fact, the elongated insulating housing 16 is mounted between the sides of the metal housing 14 13 1249277 to span the side walls of the metal housing and form the rear of the card receiving recess 26. Referring to Fig. 6, the card ejecting mechanism 20 is embedded in an internal space surrounded by the L-shaped side walls 32 (Fig. 2) of the metal casing 14. The card eject mechanism is a conventional push/push card eject mechanism and includes a cam slider 44, a coil spring 46 and a cam pin 48. The slider has a chute 44a for accommodating the guide 32d to guide the slider in a front-rear direction as shown by the double "D", and the coil spring 46 is positioned at the spring retaining projection 16e of the insulating housing 16. Up and continuously biasing the slider toward the arrow "E, shown moving forward or in the direction of the 10 out. The slider moves back and forth on the horizontal bottom section 321 of the side wall of the metal casing, and at 6th It can be seen that because the sheet metal material used for the forging of the metal casing is relatively thin, the horizontal section of the side wall can have a relatively large size or area and does not increase the height profile of the connector. There is a curved surface 15 surface 44b which is combined with a curved positioning edge of the memory card 24, and the slider has a hook portion 44d which protrudes forward and terminates at a side edge of the memory card. Therefore, when the card is inserted into the recess 26 The hook portion is "snapped" in conjunction with the card recess and the card moves with the slider 44 within the connector. As described below, the cam pin 48 has a cam pin bond secured to the card insertion guide 22. a front end in the hole 22b, and the cam pin The opposite end is inserted and operatively coupled to the cam groove in the top of the slider 44. Figures 7-10 show the operation of the card eject mechanism 2 when the memory card 24 is inserted into the connector and ejected by the connector 12. First, however, Fig. 7 shows that the memory card 24 has a recessed hole 5 at its side edge for receiving the hook portion of the slider 44 and moving the memory card together with the slider. The memory card has a majority 1249277 is recessed into the top of the card along the front edge of the card to engage the joint 52 of the contact portion 18a of the terminal 18, and a corner of the card has a curved locating surface 54 for engaging the curved surface 44b of the slider. In the prior art, the slider generally has a heart-shaped 5 cam groove 56 at its top for receiving one end 48a of the cam pin 48, and the opposite end 48b of the cam pin 48 is inserted into the card insertion guide 22 as follows. Hole 22b. The leaf spring 40, which is forged from the top wall 28 of the metal casing 14, is pushed down against the cam pin and holds the cam pin in its operative position, as shown in Fig. 7. The figure shows that the memory card is inserted outside the insertion in the direction of the arrow "C" 10 initial position, and it can be seen that the joint 52 on the memory card has not been combined with the contact portion 18a of the terminal 18. However, the hook portion 44d of the slider 44 has been elastically buckled into the recessed hole of the side edge of the memory card. 5G. Therefore, the memory card is combined with the slider to be collectively moved into the connector. Fig. 8 shows that the memory card 24 and the cam slider have been inserted into the direction of the arrow "c" 15 The final insertion position of the card is read, and at this time the leading edge of the card abuts the terminal block 16. In the prior art, this is sometimes referred to as an over-insertion and the heart-shaped cam slot 56 is operatively positioned to cam. After the memory card 24 is inserted into its final insertion position as shown in Fig. 8, the card is released, and the coil spring 46 is pushed forward in the direction of the arrow "E" to the slider 44 2〇 and the memory. Card to - the position within the lock, as shown in Figure 9. In this position, 'one of the cam pins 48 is held in a portion of the heart shaped cam groove 56' to hold the slider and the memory card in the inner position, so that the joint 52 remains opposite the terminal 18. Some ISa are combined or connected. When it is desired to eject the memory card 24 from its inner connection position, the card is pushed inwardly in the direction of the arrow "c" in the first 〇 15 1249277 view, causing the card to move back to its final insertion position. At this second push operation, one end 48a of the cam pin 48 is moved away from its position within the cam groove 56 and is now free to move longitudinally within the slot. Next, the coil spring 46 is operable to push the slider 44 and the memory card 24 outwardly toward the initial position of the insertion in the direction of the arrow ‘ 'F', as shown in FIG. As described in the prior art, the helical magazine 46 of the card ejection mechanism 20 has a tendency to fully push the memory card out of the connector under the inertia of the coil spring 46, which causes the memory card to fall out of the connector. Figure 11 shows an embodiment of a device for preventing this from happening. In detail, the 11th and 12th views show an elastic plate spring 60 which is forged from the side wall 32 of the metal casing 14. The leaf spring is a bridge member and has an opposite end 60a formed integrally with the side wall 32, and the plate magazine has a 15 direction toward the rear side 64 of the arm 44c that is coupled to the rear of the hook portion 44d of the slider 44. The protrusion 62 is internally extended. The protrusion 62 is coupled behind the hook portion 44d to force the hook portion to be retained in the recess 50 of the memory card 24 and prevent the coil spring 46 of the eject mechanism from moving the memory card 24 outwardly away from its initial state as shown in FIG. position. The slider has a tendency to incline outwardly in the direction of the arrow "G", but the projection 62 prevents this tendency to move and holds the hook portion 44d in the recess 50. Figure 13 shows the memory card 24 in its inner connection position, and it can be seen from the figure that the rear side 64 of the hook portion 44d has moved inwardly or away from the projection 62, so that the hook for holding the slider is applied. The force in the recess of the memory card is small. Therefore, if it is necessary to completely withdraw the memory card 24 from the connector, the memory card can be pushed inwardly to its inner connecting position, so that the ejecting mechanism 2 疋 locks the slider 16 1249277 44 in the money-carrying position. Then, since the force on the slider becomes small, it is possible to recall the connector. In other words, the slab is configured to provide a relatively strong resistance to prevent the fishing portion when the slider is in the initial position other than that shown in FIG. Lai pulls out 5 recesses 5 〇 but 疋, § the slider moves inwardly away from the projection 62 to its inner (locked) connection position, providing a relatively weak resistance so that the memory card can be more easily connected by the connection The device is taken out. Figures 14 and 15 show another form of the protrusion on the elastic plate spring (9). In Fig. 14, the protrusion 62 is smaller than the protrusion shape shown in Figs. The angle is formed in a V-shaped manner. Fig. 15 shows that the projection 62 has a substantially U-shape and is more inwardly convex than the shapes of Figures 12 and 13. The v-shape and the u-shape in the 14th and 15th figures The force of holding the hook portion 44d of the slider in the recessed hole 5〇 in the side edge of the memory card 24 is further increased. Fig. 16 shows the elasticity of the bridge plate spring 6 in Fig. 11 Another embodiment of the leaf spring 60A. In the embodiment of Fig. 16, the leaf spring 60A is also forged from the side wall 32 of the metal casing 14, but the plate Spring 60A is an overhanging spring arm and has an end 65 that is integral with side wall 32 and has a projection 62 located adjacent the free distal end 66 of the arm. Figure 17 shows the positioning of the metal housing 14 A card ejecting mechanism 20 is formed in the interior of the side wall 32, and the elastic plate spring 40 forged by the top wall 28 of the metal casing biases the cam pin of the ejecting mechanism to enter the sliding member 44.
