The prior art is a background of the invention. This Basso presents the wisdom of the memory circuit type 10 15 . Some forms of card readers are readable: electronic programming or memory. Such cards are used in the electronic age of the future = the use of video recorders, digital cameras, and smart models. Multi-application (PDA), music player, cash machine second line 1 = material assistant toy, game, computer adapter, multimedia card heart:: ', 'a money card including (four) through - card Lian ^ soil Then connect to the external device - the contact or terminal to read, enter and remove the card, to accept the frozen six-inch connector - the connector can be used to collect information and programs in the card. The card is connected to the terminal of the contact array of the 5 Lu Yi recall card. The word itself is read or written via the connection 11, and can be passed between the electric 11 supplies, such as the literary person, the personal poor assistant, and the like. The card can be used to identify the mobile phone stored in the SIM (User Identification Module) card, and then can be used to access the dragon's mobile phone. The SIM card has a - conduction surface of the ^ 妾 point, and the mobile phone has a SIM card connector, and the connected stone = some terminals are electrically connected with the contacts of the simple card to ensure the user identification 20 1250697 a basic The memory card connector includes some form of an insulative housing that is covered by a metal shell. The metal shell may be pressed from a sheet metal material and formed substantially in a box shape. The metal shell and the housing together define a card receiving aperture. One end of the hole is open to form a card insertion hole. The insulating case 5 body may be substantially L-shaped or U-shaped and includes a rear terminal-mounting portion on the rear end of the hole, and at least one longitudinal side wall portion is from one side of the hole or one end of the rear side of the hole Or both ends extend forward. The metal casing has a top plate that substantially covers the insulative housing, and the side panels extend downwardly on the side wall portion of the housing, and one or both side wall portions of the housing define opposite sides of the card receiving aperture. An example of such a memory card connector is disclosed in Japanese Patent Application Publication No. 2002-32953. Some card connectors include a card eject mechanism that allows the memory card to be easily inserted into the connector and the eject mechanism is used to facilitate removal of the card from the connector. Some eject mechanisms include engaging a memory card to move with the sliding elements inside and outside the connector. The latches, cams, ejectors, and other operational components are operatively associated with the slider, rather than the memory card itself. An example of a memory card connector having a 'push/push ejector mechanism' is disclosed in Japanese Patent Application Publication No. 2002-343468. The size of electrical appliances such as video recorders, digital cameras, mobile phones, personal data processing (PDA) 20 and other small electronic devices has been significantly reduced. Many such small devices are equipped with a push/push type or other form of card eject mechanism that must also be downsized to make the connector thinner. However, the insulative housing of the connector makes it difficult to reduce the size of the card connector, especially the height of the connector. The insulating housing is basically molded of an insulating plastic material, and 6 1250697 • includes a bottom plate or wall which is limited by the manufacturing area of the injection molding method and cannot be reduced to a certain thickness. (about 0.2 microns). Reducing the size and/or height of the insulative housing is limited by the fact that the eject mechanism must be mounted on the housing (e.g., on a longitudinal side wall portion of the housing) and cannot be reduced. The purpose of the invention is to solve these problems and to allow the memory card connector to have a reduced size and is particularly thin. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a novel and improved thin memory 10 card connector. In an exemplary embodiment of the invention, the connector includes a metal shell having a top wall and at least one substantially L-shaped sidewall depending from a side edge of the top wall to at least partially define A card accommodating a hole for accommodating a memory card. An insulative housing is disposed behind the aperture and is provided with a plurality of electrically conductive terminals having contacts that extend forwardly into the aperture to engage the -15 contacts on the memory card. A card for ejecting a memory card from a hole is provided. The card eject mechanism is positioned in an interior space defined by the L-shaped side walls ® of the metal shell. In accordance with a feature of the invention, the metal shell includes a pair of L-shaped sidewalls depending from opposite side edges of the top wall and defining opposite side edges of the card receiving aperture. The insulative housing includes an elongated terminal block that extends along a rear edge of one of the top walls of the metal shell between the side walls of the housing. The L-shaped side wall includes a guide bar for guiding movement of the card eject mechanism. According to another feature of the invention, the card eject mechanism includes a slider connectable to the memory card for movement with the card to the inside and outside of the aperture. The sliding 7 1250697 is movably mounted in the interior space of an L-shaped side wall. According to another feature of the invention, the slider includes a cam slot and the pop mechanism includes a cam pin operatively associated with the cam slot. A card guide is erected on a front end of one of the L-shaped side walls 5 on one side of the front insertion hole of one of the holes. One end of the cam pin is locked by a cam groove in the slider, and an opposite end of the cam pin is fixed to the card guide piece. Other objects, features, and advantages of the present invention will be apparent from the description accompanying drawings.

A card eject mechanism, generally designated 20, is mounted within one side of the metal casing and a card guide tab, generally designated 22, is disposed within a front corner of the metal casing. A memory card, generally indicated at 24, is inserted into the connector in the direction of the arrow, 'C〃 (Fig. 1A). 15 In particular, referring to Fig. 3 and Fig. 1A-2, the metal shell 14 is formed by pressing a sheet of metal material. The metal shell defines a card receiving aperture, generally indicated at 26 (Fig. 2), to accommodate a memory card 24 that includes a top plate or wall 28 and a pair of generally L-shaped side walls 30, 32 along which The opposite side edges of the top wall overhang and are combined to define the top and sides of the aperture 26. The 20 holes have a front receptacle 34. As clearly shown in Figures 1B and 2, the L-shaped side wall 30 has a vertical portion 30a bent at right angles to the top wall 28, and is bent at right angles to the vertical portion and extends inwardly from the vertical portion. A horizontal bottom 30b. A bottom guide piece 30c is formed on a front end of the side wall 30 to guide the memory card 24 to 9 1250697: in the cavity 26. The side wall 30 has a pressed erecting flange 3〇d that protrudes outwardly to secure the metal casing to a erecting pad on a printed circuit board by fusion bonding. Finally, a window 30e is formed on a rear end of the side wall 30. Similarly, the 'L-shaped side wall 32 includes a vertical wall portion 32a that is bent at right angles to the edge of one of the top walls 28 of the metal shell. A horizontal bottom portion 32b is bent at right angles to the vertical portion and extends inwardly from the vertical portion, and a flange 32c is pressed from the side wall to be erected to the printed circuit board. An elongated guide 32d is pressed from the horizontal portion 32b of the L-shaped side wall 32. The guide rod protrudes upward from the horizontal portion ί to guide a sliding member of the eject mechanism 20 as described below. As clearly shown in Fig. 2, a joint flange 36 is bent downward at the rear of the metal shell. The engagement flange has an engagement aperture 36a and a mounting flange 36b for mounting to the printed circuit board. As clearly shown in Fig. 3, a joint flange % is bent downward in front of the metal shell. Finally, an elastic leaf spring is pressed from the top wall 28 of the metal shell and rests against the inside of the side wall 32. -15 Referring now to Fig. 4A-3, the guide tab 22 is mounted on the inner side of the front end of the L-shaped side wall 32 of the metal shell 14 on one side of the hole 34. The engaging flange 38 (Fig. 3) from the top wall 28 of the gold® shell is pressed into a receiving hole 22a on the top of the guiding piece which can be molded of the plastic material (Fig. 4). A cam engagement hole 22b is also formed on the top of the guide piece to achieve the above object. Finally, the guide tab has an inwardly directed guide tab 22c that extends from the bottom wall 32b of the side wall 32 such that the memory card 24 is guided to the aperture by the bow guide tab 22c and a truncated inner surface 22d of the card guide tab 22 26 in. Referring now to Fig. 5 in conjunction with Fig. 1A-2, the insulating case is molded of a plastic material or the like to bridge the elongated terminal block of the terminal 18. The frame 10 J250697. = The plurality of perforations 16 on the terminal block also have the terminals suspended forwardly to the 妒8 26 to engage the appropriate contacts to the contacts on the memory cut. The = sub-has has a tail portion 18b (the second job picture)' to be connected by means of, for example, (4). It is suitable for the electric_line on the circuit board. The tail portion (10) of the terminal is coplanar with the metal-provided flange flanges 32c and 36b to simultaneously fuse to the end of the circuit terminal block and has a --joint projection Na to engage the window of the metal-provided side wall 30. Inside, as shown in Figure 2. The terminal block has a rear engagement projection 16C (Fig. 2) for engagement into the aperture 36a of the engagement flange 36 of the metal casing. Fig. 5 shows that at the end of the terminal block, there is a ratio of a wall (6), a member of the terminal block (6), and a spring-clamping projection that protrudes forward from the field wall. The generally elongated section 16 is spanned between the side walls of the metal shell 14 across the side walls of the shell and forms the rear of the card receiving aperture 26. Referring to Fig. 6, the card ejecting mechanism 20 is mounted in an inner space defined by the chevron side wall 32 (Fig. 2) of the metal shell 14. The card eject mechanism is a conventional 15 push/push mechanism and includes a cam slider 44, a coil spring 46 φ and a cam pin 48. The slider has a sliding elongated hole 44a that accommodates the guide bar 32d to guide the movement of the slider in the front-rear direction as indicated by double arrows, □'. The coil spring 46 is positioned on the spring catching projection 16e (Fig. 5) of the terminal block 16, and is biased by the striker in a forward or ejecting direction indicated by an arrow, E'/. The slider moves back and forth on the top of the horizontal portion 32b of the side wall of the metal shell. It can be seen from Fig. 6 that the horizontal portion of the side wall can have a height or area which does not substantially increase the connection, because the sheet metal material which is pressed into the shell is very thin. The slider has a curved surface 44b that engages a score edge of a test card. The slider has an arm 々Ac that protrudes toward 11 !25 〇 697 and ends with a hook 4 that is engaged on one side edge of the memory card such as 'so when the card is inserted into the hole 26 — the hook, the card The buckle < engages with the card slot' and the card and slider 44 - act on the connector.

First, however, Fig. 7 shows that the side edge of the memory card 24 has a slot 50 for receiving the hook of the slider 44, and collectively, the memory card and the sliding jaw. The memory card has a plurality of contacts 52 recessed along the edge of the card on the top of the card to engage the front portion 18a of the terminal 18 that is suspended toward the front. The card's - corner has a split (four) to pick up. The curved surface 44b of the slider 44. As is conventional, the slider has a heart shape at its top to accommodate the end of the cam pin 48. The opposite end of the cam pin is inserted into the hole 22b of the guide piece 22, as will be explained below. The blade spring 4 (Fig. 3) pressed from the top wall 28 of the metal shell 14 is pushed down on the cam pin and maintains the cam pin in the operating position shown in Fig. 7. position. It can be seen that the contact s52 on the memory card has not yet been engaged with the contact portion 18a of the terminal i8. However, the hook portion 4 of the slider 44 is elastically, snapped, to _5G on the side edge of the memory card. Thus the 'memory card and slider are engaged' to move further into the connector. Figure 7 shows the first h 20 direction plug-in terminal block inserted in the direction of the arrow, C „ direction. Figure 8 shows that the memory card 24 and the slider 44 have been inserted into the memory card by the arrows, and c. The front edge of the field is referenced by 12 1250697 16. This is sometimes referred to as over-insertion to allow the heart-shaped cam groove 56 to operatively position the cam pin 48 as is conventionally known. The memory card 24 is inserted into Figure 8. After the fully inserted position is shown, the card is released and the coil spring 46 advances the slider 44 5 and the memory card forward in the direction of arrow 'E 回到 back to the locked/connected position shown in Fig. 9. Next, one end 48a of the cam pin 48 is locked in a portion of the heart shaped cam groove 56 to support the slider and the memory card in the locked/connected position, and the contact 52 maintains the connection with the contact portion 18a of the terminal 18. Or when engaging. When the memory card 24 is to be ejected from the connector, the card is again pushed inward in the direction of the arrow ''c〃 in the 10th 10th figure, so that the card moves back to its fully inserted position. Here the second In the propulsion operation, one end 48a of the cam pin 48 is self-contained within the cam groove 56. The dwelling position is removed and is now free to move longitudinally within the elongate hole. Then, the coil spring 46 becomes operable to advance the slider 44 and the memory card 24 in the direction of the arrow ''F〃' (Fig. 10). Returning to the initial insertion position shown at 15 in Figure 7. The card can then be removed from the connector. From the above, it can be seen that the card ejection mechanism 20 operates exactly as in the prior art, but the ejection mechanism is not mounted on the connection. Any bulky portion of the device, such as a bulky sidewall portion of an insulated molded plastic housing. The ejection mechanism of the present invention is entirely erected in the interior space of the L-shaped sidewall 32 of the metal shell 14. Similar to the entire 20 metal shell, The side walls are made of a thin metal foil, and since the thin thickness of the metal material itself occupies a small space in the vertical direction, the height of the connector can be remarkably reduced. In fact, the width of the connector is due to the insulation or the plastic shell. The body is significantly reduced without any bulky side walls.
