Description of the invention: [Technical field to which the invention belongs] Field of invention 5 The present invention relates generally to an electrical device and a memory card connector. The technology of air connector and especially [pre-existing technology] Background of the invention, memory card is well known in the prior art and contains information in the form of-memory circuit or other electronic programs, and some # 卡 机 硕 取 取Information or memory on the card. These cards are used in Xu Xi applications in today's electronic society, including cameras, digital still cameras, smart electric years, PDAs, music players, ATMs, cable TV decoders, toys, games, pc connectors , Multimedia cards and other electronic applications. Normally, the ⑳card spoon includes a connector or terminal array for connecting to the card reading system through a -card connector and then the shaft = 15 external devices. The connector can easily fit with the card. • Insert and withdraw quickly to get information and programs on the card, and the card connector includes most terminals that are used to deformably combine the connector array of the memory card. The memory card connector is often mounted on a printed circuit board. The memory card itself can be read and written through the connector and can be used between electrical appliances such as text processors, personal computers, personal digital assistants, etc. transfer. The card can be used in a variety of applications such as mobile phones or mobile phones. These mobile phones or mobile phones can be activated and allow data access after identifying a stored on a SIM (Subscriber Identity Module) card. The SIM card has a conductive surface with a connector array 200531376, and the mobile phone has a SIM card, and the SIM card has most of the terminals for electrically connecting the SIM card connector to ensure the user identification certificate. A typical memory card connector includes an insulating shell of a certain shape covered by a metal cover, and the metal cover can be forged and formed from a sheet metal material to form a substantially box shape. The metal cover and the casing together define a card receiving recess, and the recess is open to form a card insertion opening. The insulating housing may be substantially L-shaped or U-shaped and includes a terminal mounting section 'behind the recess and at least one of the rear sections, 10 or both ends extending forwardly at one or both sides of the recess. Longitudinal sidewall segment. The metal cover has a top plate that substantially shields the insulating case, and most of the side plates extend downwardly on the outside of the side wall section of the case. One or both of the side plate of the metal cover and / or the side wall section of the housing defines the side of the card receiving recess. Examples of these connectors are disclosed in Japanese Patent Nos. 20002-329553 and 20002 343468. 15 Some card connectors include a card ejection mechanism whereby the memory card can be inserted into the connector, and the card ejection mechanism can be used to assist the card in the quick connection. Remove it. Some ejection mechanisms include a majority of sliding members that incorporate the memory card and move them in and out of the connector. Then, the latch, cam, ejection device, and other operating elements are operatively connected to the slider instead of the 20 The card itself. A card ejection mechanism includes a heart-shaped cam groove in the slider, and a pin member is operatively biased into the heart-shaped cam groove, and under normal circumstances, a spring member is used to bias a The slider is in the direction of exiting the needle. This card ejection mechanism is called-"push / push type. Ejector" where the memory card is first pushed into the recess of the connector and reaches the operating position of a lock 200531376 buckle, and- The second push effectively releases the card and allows the spring to eject the card from its locked position. Figures 18 and 19 show a conventional push / push memory card connector 70, and the connector includes a The insulating case is generally indicated by 72, and the insulating case 72 series 5 is shielded by a metal case generally indicated by 74, and the metal case 74 is combined with the case to form a card storage for receiving a memory card 76 Recess. A card ejection mechanism, generally designated 78, is mounted on the housing and includes a push / push type of a cam slider 80, a cam pin 82, and a spiral ejection spring. The longitudinal side wall 72a of the casing is moved between an initial position (FIG. 18) outside the insulating casing 72 for receiving 10 nanometers and an internal connection position, and most of the internal connection position is in the memory. The 76a combination on the card is indicated generally by 86 and is installed behind the housing The terminal on the sub-mounting section 72b. The cam slider 80 has a hook 88 that is detachably held in the recessed hole 76b of the memory card 76, so the memory card and the slider are in the outer initial position 15 with the The metal housing 74 includes a top wall 74a and a side wall 74b. As shown in FIG. 19, the hook 88 is configured so that its rear side 90 faces the top wall 74a of the metal housing 74. The metal housing 74 There is a bridge-shaped elastic piece 92 formed by the side wall 74 b, and the opposite end of the elastic piece is not cut or connected to the side wall, and the elastic piece 92 20 is provided as a cam slider on the side 90 after the hook 88 When it is in the initial position outside, it can push the slider. When the memory card 76 is inserted into the card receiving recess, the hook 88 is first pushed out against the elastic piece 92, and then the hook "buckles" into the memory card. The recessed hole 76b 'leaves a gap between the rear side 90 and the elastic piece 92 of the angle 94 ° 7 200531376 This push / push type using a spring member to spring the card away from its locking position and other types of ejection There are many problems with the mechanism, for example, it is necessary to maintain the spring force in the spring member. difficult. If the ejection spring is relatively weak, it will be difficult and unsatisfactory to eject and remove the memory card. On the contrary, if the ejection spring is too strong, the card and the sliding member will be quickly driven in the ejection direction, and in fact, the memory card will eject the card connector and fall to the ground. Under the action of the spring force of the strong ejection spring, the bridge-like elastic piece 92 of the conventional memory card connector 70 shown in Figs. 18 and 15 is insufficient to prevent fishing from being pulled out of the recessed hole 76b in the memory card. The present invention intends to solve these problems by preventing the memory card from coming out of the connector even if a strong elasticity that ejects the memory card with a full-speed and fast movement is used. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a new and improved memory card connector having the aforementioned characteristics. In this "Mingzhi-Yuan" embodiment, the memory card connector includes an insulating ㈣ with a-terminal mounting section, and the terminal mounting section is installed with a plurality of suitable connectors for bonding to a notebook U 卞.

The metal casing 14 is formed by forging of 11 200531376 sheet metal material. The metal case defines a card receiving recess, generally indicated by 26, for receiving the memory card 24. The metal case includes a top plate or top wall 28 and a pair of substantially B-shaped side walls 30 extending downwardly along the top wall. 32. Together, the L-shaped side walls 30 and 32 define the opposite 5 side edges of the recessed portion, and the recessed portion has a front insertion opening 34. As shown in Figs. 1B and 2, the 1 ^ -shaped side wall 30 has a vertical section 30a which is "bent 90 degrees" from the top wall, and a horizontal bottom section that is bent 90 degrees from the vertical section and extends inwardly therefrom. 30b. A bottom section guide 3 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 forming mounting flange 30d, and the mounting The flange 30d 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 bent 90 degrees along the edges of the top wall 28 15 of the metal housing, and a horizontal bottom section 32b is bent 90 degrees relative to the vertical section and extends inwardly therefrom. The mounting flange 32 (: is forged from the side wall® and can be mounted on the printed circuit board. An elongated guide 32d is forged from the horizontal bottom section 32b of the L-shaped side wall 32, and the guide The horizontal section protrudes upward to guide the sliding member of the card ejection mechanism 20 as described below. As shown in FIG. 2, a coupling flange 36 is articulated behind the metal housing, and the 4 coupling flange has a coupling opening 36 a and a mounting flange 36 b for mounting to the printed circuit board. As shown in Fig. 3, a coupling flange 38 is bent in front of the metal casing and downward on the inside of the side wall. Finally, an elastic leaf spring 40 is forged and formed from the top wall 28 of the metal casing, 12 200531376, and is close to L The inner side of the side wall 32. Referring to FIGS. 4 and 1A-3, the card insertion guide 22 is installed 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. The metal casing The top wall 28 is a downwardly extending coupling flange 38 (FIG. 3) 5 is pressed into a latching hole 22a (FIG. 4) fitted in the top of the guide, and the latching hole 22a is molded from a plastic material A cam pin coupling hole 22b is also formed in the top of the guide member to achieve the purpose described below. Finally, the guide member has an inward guide plate 22c that continues the bottom section 32b of the side wall 32, thereby memorizing The card 24 can be guided into the recess 10 by the guide plate 22c and the chamfered inner surface 22d of the card insertion guide 22 Please refer to Fig. 5 and Figs. 1A-2. The insulating case 16 is a one-piece structure molded from a plastic material and the like, and is a long terminal block for mounting a large number of terminals 18. These terminals are installed In most of the through holes 16a in the terminal block, the terminals have a majority of the contact portions 18a overhanging into the recesses 26 to fit the appropriate connectors on the 15 memory card 24. The terminals have a majority of So as to be connected to the tail portions 18b of appropriate circuit lines 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 be simultaneously soldered to the Circuit board. The terminal block has a coupling protrusion 16b at one end for coupling in the window 30e of the side wall 20 30 of the metal casing, as shown in FIG. 2. The terminal block has a rear engaging projection 16c (Fig. 2) for engaging in the opening 36a of the engaging flange 36 of the metal case. 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 case 16 is installed between the sides of the metal case 14 and the 200531376 wall, and bridges the side wall of the metal case and forms the rear part of the card receiving recess 26. Referring to FIG. 6, the card ejection mechanism 20 is embedded in an internal space surrounded by the household body's L-shaped side wall 32 (FIG. 2). The card ejection mechanism is a conventional push / push card ejection mechanism and includes a cam slider 44, a coil spring 46 and a cam pin 48. The slide member has a slide groove 44 a for accommodating the guide 32d to guide the slide member to move forward and backward as shown by the double arrow “D”, and the coil spring 46 is positioned on the spring holding projection of the insulating case 16 16e and continuously bias the slider toward the arrow "E," as shown in the forward or spring direction. The slider moves forward and backward on the horizontal bottom section 32b of the side wall of the metal casing, and moves on the 6th It can be seen in the figure that because the sheet metal material used for the metal shell forging is quite thin, the horizontal section of the side wall can have a relatively large size or area without increasing the height profile of the connector. The slider The curved surface 15b 44b is provided with a curved positioning edge of the memory card 24, and the slider has a hook portion 44d protruding forward and terminating at a side edge of the memory card. Therefore, when the card is inserted into the recess 26 , The hook portion "clicks" and combines with the card recessed hole and the card moves with the slider 44 in the connector. As described below, the cam pin 48 has a wheel pin fixed to the card insertion guide η. Coupling hole 22b_front end, and the cam-like opposite end A cam slot inserted and operatively connected to the top of the slider 44. Figures 7-10 show the operation of the card ejection mechanism 20 when the memory card 24 is inserted into the connector and ejected by the connector 12. However, First, FIG. 7 shows that the memory card 24 has a recess at the side edge thereof for receiving the fishing part of the slider 44 and moving the memory card and the slider together. The memory card has a majority of 14 200531376 The top of the card is recessed along the leading edge of the card to join the connector 52 of the contact portion 18a of the terminal 18, and a corner of the card has a curved positioning surface 54 for engaging the curved surface 44b of the slider 44. As in Generally, in the prior art, the slider has a heart-shaped 5 cam groove 56 on the top thereof for receiving one end 48a of the cam pin 48, and the opposite end 48 of the cam pin 48 is inserted into the card insertion guide as described below. 22 的 孔 22b. The leaf spring 40 forged from the top wall 28 of the metal casing 14 is pushed down on the cam pin and holds the cam pin in its operating position, as shown in FIG. Figure 7 shows that the memory card is inserted in the direction of the arrow "c" beyond the beginning. It can be seen that the connector 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 snapped into the recess 50 in the side edge of the memory card. Therefore, the memory card and the slider are combined together to re-enter the connector. Figure 8 shows that the memory card 24 and the cam slider 44 have been inserted into the memory card in the direction of arrow "C" 15 To the final insertion position, and at this time the leading edge of the card is against the terminal block 16. In the prior art, this is sometimes referred to as a state where over-insertion allows the heart-shaped cam groove 56 to operatively position the cam pin 48. After the memory card 24 is inserted into its final insertion position as shown in FIG. 8, release the card so that the coil spring 46 pushes the slider 44 forward in the direction of the arrow “E”. The locked inner connection position is shown in Figure 9. In this position, one end 48a of the cam pin 48 is held in a part of the heart-shaped cam groove 56 to hold the slider and the memory card in this position, so that the joint 52 is kept in contact with the terminal 18 Portion 18a is bonded or linked. When the memory card 24 needs to be ejected from its internal connection position, push the card inward in the direction of the arrow "c" in Fig. 10 15 200531376 to move the card back to its final insertion position. During this second push operation, one end 48a of the cam pin 48 is moved away from its position held in the cam groove 56 and is now freely movable in the groove in the longitudinal direction. Next, the coil spring 46 is operable and pushes the slider 44 and the memory card 24 back to the initial position of the insertion in the direction of arrow "F", as shown in FIG. As described in the prior art, the spiral spring 46 of the card ejection mechanism 20 has a tendency to completely push the memory card out of the connection under the inertia of the coil spring 46, which will cause the memory card to fall out of the connector. Figure U shows an embodiment of a device to prevent this from happening. Specifically, FIGS. 11 and 12 show an elastic leaf spring 60 formed by forging and forming the side wall 32 of the metal casing 14. The leaf spring is a bridge-shaped member and has an opposite end 60a integrally formed with the side wall 32, and the leaf spring has a 15-direction to the rear side 64 of the arm 44c facing and coupled to the rear side of the hook 44d of the slider 44内 Extending the protrusion 62. The protrusion 62 is combined 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 ejection mechanism from moving the memory card 24 outward from its initial position shown in FIG. 12 position. The slider has a tendency to tilt outward in the direction of the arrow "G", but the protrusion 62 prevents this tendency to move and holds the hook portion 44d within the recessed hole 50. 20 Figure 13 shows that the memory card is in 24 positions in its internal connection position. It can be seen from the figure that the rear side 64 of the hook portion 44d has moved inward or away from the protrusion 62, so that the hook applied to hold the slider is applied. The force embedded in the recess of the memory card is small. Therefore, if the memory card 24 needs to be completely pulled out of the connector, the memory card can be pushed inward to its internal connection position, so that the ejection mechanism 20 locks the slider 16 200531376 44 in the connection position. Or, because the force on the slider becomes smaller, the memory can be replaced with a leaf spring 60 series, .. 5 dogs 62 and the slider to the slider in Figure 12 Beginning when not shown, when placed, it provides-relatively strong resistance to prevent the fish paste from coming out of the recessed hole 50. However, the "moving" piece moves away from the protrusion 62 into it (locking) connection When in position, provide relatively weak resistance, such as', so that the memory card can be more easily removed from the connector.
