[Previous Background of the Invention Memory cards are conventional in the prior art and contain information in the form of a memory circuit or other electronic program, and some card reader reads the information or memories 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, atm, cable TV decoders, toys, games, PC connectors, multimedia Cards and other electronic applications. Generally, a memory card includes a connector or terminal array for connecting to a card reading system through a card connector and then to 15 external devices. The connector can easily cooperate with the insertion and extraction of the card to quickly obtain the information and programs on the card, and the card connector includes most terminals for deformably combining 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 transferred between electrical appliances such as word processors, personal computers, personal digital assistants, etc. . The card is 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 1237421, 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 case of the same shape, and the 5 insulating case is generally covered by a metal outer cover as disclosed in Japanese Unexamined Patent Publication Nos. 2001-291552 and 2002-23751. The metal outer cover may be The sheet metal material is forged and formed into a substantially box shape. The metal cover and the housing together define a receiving recess, which 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 10 behind the recess, and at least one extending forward from one or both ends of the rear section at one or both sides of the recess. Longitudinal sidewall segment. The metal cover has a top plate that substantially shields the insulating housing (at least its contact interface area), and most of the side plates extend downwardly outside the side wall section of the housing. The side plates of the metal cover and / or the side wall sections of the casing together define the sides of the receiving recess of the card 15. § When the connector structure is installed on a printed circuit board, a reinforcing device of the same form may be provided to fixly connect the connector to the printed circuit board by, for example, welding and through the metal cover. The most typical system is to provide one or more reinforcing 20 members that are separate or integrally formed from the side plate of the metal cover. These reinforcing members are made of metal materials and are fixedly connected to the circuit board by welding. . Figures 12 and 13 show an example of a board mounting system using a reinforcing member generally designated as 14, and the reinforcing member 14 is generally designated as 18 by a typical memory card connector mounted on a printed circuit board 20. The side plate of the metal cover 1237421 is forged. The reinforcing member 14 is composed of a pair of horizontally divided cuts or slits 22 which are opened at the bottom edge 16a of the side plate 16 and extend upwardly into the side plate by about one and a half height of the side plate. As shown in FIG. 13, the reinforcing member 14 is substantially L-shaped to define a vertical plate portion 14a and a horizontal plate portion 14b protruding outward from the side plate 165. The reinforcing member 14 is fixedly connected to a suitable mounting pad on the circuit board 20 by a soldering pad 24. With the aforementioned board mounting system, the load on the memory card connector is absorbed by one or more reinforcing members 14 integrally formed with the metal cover 18 and soldered to the circuit board 20. The metal material of the metal cover that is forged and formed has a thickness of about 10 mm. Therefore, the reinforcing member 14 formed by the slit 22 that extends only about half the height of the side plate 16 cannot have obvious elasticity. Remember that the metal The outer cover is rigidly fixedly connected to the non-conductive or insulating case, and the case has a thermal shrinkage greater than that of the printed circuit board. Therefore, when a temperature change occurs in a re-soldering process, the case and the circuit board There will be a heat shrinkage change in between, and this heat shrinkage change will deform the metal cover. In other words, 'because the reinforcing member 14 lacks elasticity, the side plate 16 of the metal cover cannot deform with this deformation', as a result, a stress is applied to the welding pads 24. Therefore, 'cracks or micro-cracks may be generated in the packing and the electrical connection with other terminals of the connector may be unreliable. In fact, the mechanical 20 peel resistance is reduced due to the lack of flexibility or elasticity of these reinforcing members. In addition, 'when the reinforcing member 14 is soldered to the circuit board 20, excess solder will flow upward along the vertical plate portion 14a of the reinforcing member, as shown in FIG. 13' This excess solder hardens and reduces the connector The visibility of the card receiving recess and / or the memory card cannot be smoothly inserted into the recess. 1237421 The present invention is intended to solve these problems. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a memory card connector having an improved circuit board mounting device or system. In one embodiment of the present invention, the connector is used to be mounted on a circuit board and includes a housing mounted with a plurality of terminals, and the terminals have a plurality of suitable connectors for coupling to the memory card. The contact part. A metal cover is mounted on the casing and combined with it to define an internal card receiving recess for receiving the 10 memory card. The metal cover includes a top plate defining a main portion of a top portion of the recess. At least one side plate extends along the side edge of the top plate and projects downwardly at a right angle to it, and a plate mounting section is formed by the side plate and is defined by a pair of slits in the side plate, and The slits are configured to provide the maximum flexibility and 15 elastic characteristics of the installation section. A soldering lug is integrally formed with the bottom edge of the mounting section and protrudes outward between the slits from the bottom edge to connect the mounting section to the circuit board by, for example, soldering. According to an embodiment of the present invention, the slits extend all the way from the bottom edge of the side plate at the welding tab to the top of the side plate at the side edge of the top plate. The top plate is bent downward, and the slits extend completely through the bent portion. According to another embodiment of the present invention, the mounting section includes an opening therethrough and between the slits to increase the pullability of the mounting section. The opening is elongated in a direction substantially parallel to the top plate and the circuit board, and the 1237421 mounting section is bent downward by the top plate, and the opening extends between the slits along the bent portion. According to another aspect of the present invention, the mounting section has a predetermined width between the slits and in the longitudinal direction of the side plate. At least all the seams are generally in the shape of 15 to define a slit end that extends toward another slit and forms a narrow connecting portion, which combines the mounting section and the metal cover to make the mounting section flexible and elastic. . As disclosed herein, the two slits are generally in the shape of an inverted L to define a narrow connection between the ends of the slits that extend inwardly, and the slit ends may be at the side edges of the top plate. Extend inward. 10 According to yet another embodiment of the present invention, the inwardly extending slit ends of all the slits extend substantially through the mounting section toward the other slit to locate the narrow connection portion at the other slit. Finally, a feature of the present invention includes that the mounting section is provided with a pocket portion 'in its inner side surface, and the pocket portion accommodates excess solder during the soldering process. 15 Other objects, features and advantages of the present invention will be understood from the following detailed description in conjunction with the accompanying drawings. The drawings briefly explain that I believe that the new features are specifically disclosed in the scope of the following patent applications.

Various embodiments of the present invention are here connected by a memory card generally represented by 30 "The memory card connector 30 is mounted on a printed circuit board with a designation 1237421 indicated generally at 32." The connector consists of two main components, namely a non-conductive or insulating housing, generally designated -34, and a metal housing, generally designated 36. The casing can be molded from an insulating material such as plastic, and the metal cover is forged from a conductive sheet metal material. The casing and the cover combination 5 form an internal card receiving recessed portion generally indicated by 38, and the card receiving recessed portion 38 has a card insertion hole 40 (Fig. 1).

The casing includes a bottom plate 46, and the entire casing has a bottom surface 48 for mounting on the top of the printed circuit board 32. Most of the terminals indicated generally at 50 are installed in the passages 52 in the terminal mounting section 42 located behind the housing, and each terminal includes a tail portion 50a which is approximately 4 levels from the bottom surface I5 surface 48 of the housing, so that If soldered, it is connected to the appropriate signal circuit line 54 on the circuit board 32. These terminals also have a majority of the contact portion 50b at the distal end of the contact arm 50c to incorporate the majority on a memory card, such as a suitable connector on the bottom of the card. A conventional double-push card ejection mechanism indicated generally at 58 is mounted on the 20 side wall section 44. As is known to all, the card ejection mechanism is provided with a cam slider 60, a cam lock 62 and a coil spring 64. In short, the cam slider 6q has a combination of protrusions that can be combined with the recessed holes of the side edges of the memory card 56 to slide therewith. The coil spring 64 normally biases the cam slider-cam lock 62-end 62a to the side wall section 44 in the direction of the insertion hole 4 (), and the cam 11 1237421 opposite end 62b of the pin is combined in a heart-shaped cam Within the groove 64. The memory card is inserted into the card accommodating recess 38 until the card reaches its fully inserted position 'as shown by the dotted line 56A in FIG.胄 When the pressure on the card is released, the ejection mechanism biases the card back to position 56B. In this position, the contact portion 50b of the terminal 50 remains electrically connected to the appropriate connector on the memory card. -A second "push" on the memory card causes the ejection mechanism to bias the memory card to eject to the eject position 56 (:. Please refer to Figures 2-4, a metal "stud approximately indicated by 66" Is fixed in the slot 68 in the side wall section 44 of the housing, and the metal stud% 10 is connected to a suitable mounting pad on the circuit board by, for example, soldering. The L-shaped aspect is similar to the prior art metal reinforcing member 14 shown in FIGS. 12 and 13, but the stud is a separate member and the stud is before the metal cover 36 is assembled to the housing. 15 Please refer to FIGS. 1, 3 and 4. The metal cover 36 is substantially rectangular and includes a top plate 36 a defining a main portion of the top of the card receiving recess 38. The metal cover has a pair of > The side plates 36b and 36c of which the opposite side edges of the top plate 36a extend and hang downward at a right angle. The side plate 36b covers the outer side of the card ejection mechanism 58 and 36c forms the opposite side of the card receiving recess 38. The side plate 36c has a rim 20 the inward flange 36d formed by the bottom edge, a pair of coupling tabs 36e and 36f Top-plate 36a is forged and protruded downward into a suitable slot in the top of the housing 34 to secure the metal cover to the housing.

In detail, the conventional embodiment of FIG. 7 also includes a plate mounting section 70 having a body plate 72 and solder bumps μ, and the excess solder pocket portion 86 is also formed in the inner side surface of the body plate 72. However, in the second embodiment, the slit ends 78a and 80a extend along the side plate 36c upward from the bottom edge of the side plate to the top of the side plate at the side edge of the top plate 36a. In other words, the main body plate 72 is bent downward by the top plate 36a of the metal cover, and the slits 78 and 80 are fully extended and pass through the bent portion-88 (Fig. 7). FIG. 8 shows a third embodiment of the present invention which is substantially the same as the second embodiment, except that a side formed along the top of the body plate 72 and close to the top plate 36a of the metal cover is added. Edge of the opening 90. Similar to the slits 78 and 80 in Figs. 7 and 8, the opening 90 extends into and passes through the bent portion between the body plate 72 and the top plate 36a of the cover. The second embodiment of FIG. 7 obviously increases the flexibility and elasticity of the mounting section of the prior art. The opening 905 enters another level and provides a narrow connection for the body plate 72 to bend around. The portion 92 further increases flexibility and elasticity.
