屬材料片衝壓而形成。殼體及殼套係組合以界定一具有一 卡插入開口 28(第1及3圖）之内部卡接收腔體27(第2及3圖）。 如第2圖清楚地顯示，模製的塑料介電殼體24可概呈u 1267240 形（未圖示）或L形（如圖所示）。任一情形下，殼體皆具有一 橫越腔體27後方之後端子安裝段30,以及一從後段一端往 前延伸以界定腔體27—側之縱向側壁段32。殼體包括一用 於界定腔體體部之底壁34。 複數個端子36在殼體的後端子安裝段30中安裝於複數 個貝牙通道38内。各端子具有一從懸臂式往前進入腔體27 内之接觸部36a，藉以接合一插入腔體27中的正常尺寸記憶 卡40上的適當接觸件。 將一習知的推-推(pUSh-pUsh)型卡退出機構42安裝在側 10壁段32上。已公知此卡退出機構構成有一凸輪滑件料、一 凸輪銷46及一線圈彈簧48。簡言之，凸輪滑件44具有一接 合突部44a以接合正常尺寸記憶卡4〇的一前導邊緣4加。線 圈彈簧48通常在-朝向卡插入開口 Μ之方向將凸輪滑件料 偏壓。凸輪銷46的一端46a接合側壁段32，凸輪銷的一相對 15縞4你接合在一心形凸輪溝槽50内。 正第尺寸兄憶卡40插入卡接收腔體27内直到卡抵達其 凡王插入位置為止（第5圖）。凸輪滑件44隨著記憶卡移動， ==_簧48。當卡上的壓力被釋放時，依據凸輪槽

頂壁26a的相對側邊緣延伸且概以直角自該處往下懸吊之 —對側壁26a及26b。側壁26a覆蓋住退出機構42及殼體的側 壁段32外側。側壁26b界定腔體27的相對側。側壁具有沿著 其底邊緣往内彎轉的凸緣26c。複數個開孔狀、往外彎轉的 安裝籤片26e提供了用於將連接器安裝至一下層結構之裝 置。最後’金屬殼套的一彈簧臂2分係衝壓而形成以接合退 出機構42的凸輪銷46頂部，以將凸輪銷的端點4613偏壓至此 1〇機構的心形凸輪槽50内。 芩照第3及5圖，記憶卡連接器22與一電器52一起裝設 ，此電器52具有一與連接器的卡接收腔體”重合之卡接收 通道54。通道54具有一對準於腔體的前插入開口 28之口部 54a ° 第1至15圖顯示本發明的第一實施例之各種不同版本 ’而第16至20圖顯示本發明第二實施例之—版本。圖中類 似的編號盡可能代表兩實施例所有版本中類似的元件。基 2上述瞭解，此時當，然知道本發明包含了提供在一介於腔 出仅的插人開π 28與端子36的闕部36am的位置上延伸 至腔體27中之至少—彈簧構件6〇。在第1至15圖的第-實施 =之三種版本中’彈簧構件师金屬殼套26_壁施往下 =起。第16至2G圖的第二實施例中，彈簣構件從殼體^的 &壁^往上延伸。在兩實施例的所有版本中，較佳有複數 固彈簧構件在記憶卡插入方向中呈橫向分隔。譬如，第涓 1267240 顯示兩個在金屬殼套26的頂壁26a中衝壓出開口 ， J W而形成 之彈簧構件60。如第3圖所示，彈簧構件60朝向腔體後方以 角度或歪斜地懸臂式進入腔體27内。如下令& 一 | 乂所示，這對 於本發明的第二實施例亦然成立。 5 參照第4圖，各彈簧構件60包括一歪斜或往下成一角产 地延伸至腔體27内之斜角狀臂部64。一制動部的定位在^ 角狀臂部的一末端上。制動部為凸形且界定一面對一艽产 卡的插入方向之彎曲或凸形表面66a。 心 茶照第5圖及第4圖，當-正常尺寸記憶卡4〇插入腔體 10 27内時，記憶卡的一前導端40a將接合斜角狀臂部私(第4圖 )並將整體彈簧構件往上偏壓。隨著正常尺寸記憶卡持續插 入’彈簧構件的制動部66往上偏壓至正常尺寸記憶卡插入 腔體之路徑外，而不與彈簧構件60產生任何干擾，如第5圖 所示。 15 現在，第3、6及7圖顯示一在箭頭A方向插入腔體27之 正常尺寸記憶卡70的順序圖。記憶卡具有一前導端7加及一 尾鳊70b。使用者在正常尺寸記憶卡的尾端7〇b推押直到前 $、70a接合彈黃構件的制動部66為止。可防止記憶卡進 步插入。當使用者釋放小尺寸記憶卡的尾端70b時，彈簧 構件60可有效將小尺寸記憶卡在箭頭b方向中（第7圖）偏壓 或推押回到腔體27外。 第8至11圖顯示衝壓出金屬殼套26的頂壁26a而形成且 往下歪斜地延伸至腔體内之彈簧構件60的第二版本。在第8 至11圖的第二版本中，彈簧構件再度包括一斜角狀臂部64 12 1267240 。然而，斜角狀臂部的末端如74般地單純以輕微角度往上 彎轉，所以臂部的末端不會損傷一插入腔體27之正常尺寸 記憶卡的頂表面。易言之，斜角狀臂部的末端不像第一版 本般地具有用於抵靠住一小尺寸記憶卡7〇的前導端7如之 5 確定的制動部。 然而，第8至11圖顯示包含在兩實施例所有版本中之本 發明的一特性。具體言之，電器52中通道54的口部54a與彈 簧構件60之間的距離近似等於小尺寸記憶卡的長度（亦即 卡的前導端70a與尾端70b之間）。因此，當小記憶卡完全插 ίο入第η圖所示的位置時，卡的尾端70b與口部54a齊平且使 用者絲毫無法將一卡進一步插入腔體27内。當人員釋放此 卡時，彈簧構件60將卡在箭頭B方向中偏壓或推押回到腔體 外。經由本發明之兩實施例的所有版本來進行此現象。因 此，因為每當使用者將小記憶卡插入及釋放時此卡均會被 15往外推回，使用者顯然可發現到小尺寸記憶卡的錯誤插入 。此外，小尺寸記憶卡不能夠被完全插入其中將無法取出 或可能損傷端子36的接觸部36a之腔體内。 第12至15圖所示的本發明第一實施例之第三版本與前 兩版本之相似點係在於彈簧構件6〇具有一衝壓出金屬殼套 20 26的頂壁26a而形成之斜角狀臂部64。並且，斜角狀臂部再 度朝向腔體後方歪斜地往下懸臂式進入腔體27内。在第U 至15圖的此第三版本中，斜角狀臂部64的末端上之制動部 66係提供一小尺寸記憶卡之很確實的阻止作用。具體言之 ，制動部66為鉤形以界定—面對—記憶卡的插人方向之囊 13 1267240 ^ 鉤形制動部在一圓形接合部74上接合至斜角狀臂部 鉤形制動部66的極末端係由一特定長度的一接合壁76 所界定。 田正$尺寸記憶卡插入腔體27内時，藉由第12至15 圖所不的本發明第—實施例之第三版本，前導端他(第5圖 )再度接口斜角狀臂部64並將彈簧構件往上偏壓。隨著彈菁 構件往上偏壓’當記憶卡移入其在腔體”中的完全插入位 置時，記憶卡將沿著圓形接合部74騎乘。如上述，接合壁 76具有-特定長度’亦即此壁具有狗短的長度而足以使其 1〇移動至正常尺寸記憶卡的插入路徑外。 :、、;、而弟及15圖顯示一被插入直到卡的前導端 ?〇a接合在彈構件60之鉤形制動部的的囊部6价内為止之小 尺寸記憶卡70。當使用者釋放此卡時，彈簧構件再度有效 運作而將記憶卡推回到腔體外。 15 第16至20圖顯示本發明第二實施例，其中使彈簧構件 6〇身為分離的構件且具有一固定在殼體24的底壁34之一孔 杈82中（第18圖）之安裝腳80。彈簧構件6〇由彈簧金屬材料衝 壓而形成，其中腳80藉由壓入配合而插入塑料殼體的孔經 82内。 2〇 特別參照第18圖，彈簧構件60與第12至15圖所示的第 一實施例之第三版本相同，差異在於斜角狀臂部64朝向腔 體後方以一角度或歪斜地往上懸臂式進入腔體27内。比較 第二實施例的第18圖與第一實施例第三版本的第13圖可看 出，唯一差異在於第二實施例的彈簧構件60往上斜角狀延 14 1267240 伸至腔體27内，實施_彈簧構件_以—角度往 下延伸至腔體内。因此，已經利用類似的編號來界定:動 部66、囊部66b、接合部74及接合壁76。 5 10 第16至20圖的第二實施例之操作係與上文對於第12至 15圖所示的第-實施例第三版本所描述者相同。—正常尺 寸記憶卡將接合斜練料64並將彈簧構件往下偏壓，其 中當接合壁76移動至正常尺寸雜卡的插人路徑外時正常 尺寸記憶卡的底部將沿著圓形接合部74騎乘。小尺寸 記憶卡70插人腔體27内時，小尺寸記憶卡的前導端7〇a將被 彈簧構件_形制動部66所阻止，如㈣圖所示。 可瞭解本發明可以其他特定形式實施而不脫離本發明 之精神與中^特徵。因此，將這些目前的範例及實施例在 各方面視為示範性f而非限制性質，且本發明不限於此處 供的細節。 15【圖式簡單說明】

summarizes the art of electrical connectors and is particularly related to a card connector. t first ^ only to make up ί 3 Background of the invention 3, the card is known for this technology and contains the wisdom of the memory circuit or other forms of emperor. Part of the form of the card reader reads the information or memory stored on the card 10. These cards are used in many of today's electronic society, including video cameras, digital still cameras, smart phones, PDAs, music players, ATMs, cable TVs, toys, game consoles, PC adapters. , multimedia cards and other electronic applications. The Jiyi card includes a contact or terminal array that is connected to the card reader system via a connector and that is connected to the external δ after 15 ports of operation. This connection is easy to accommodate the insertion and removal of cards for quick access to information and programs on the card. This card connector includes terminals for the contact array of the docked memory card. The memory card itself is written or read via a connector and can be transferred between appliances such as a word processor, a personal computer, a personal digital assistant or the like. The card can be used in applications such as action or cellular activity that are activated or allowed to access data after identification of the identification stored on the -SIM (Subscriber Identity Module) card. The SIM card has a conductive surface comprising an array of contacts, and the mobile phone has a SIM card connector having terminals for making electrical connections to the components of the SIM card to ensure user confirmation. 1267240 A typical memory card connector includes a dielectric housing in the form of a portion covered by a metal sheath. The metal casing can be formed by stamping a sheet of metal material and forming a substantially box shape. The metal casing and the casing are combined to define a card receiving cavity. One end of the cavity is opened to form a card insertion opening. The dielectric housing 5 can be substantially L-shaped or U-shaped and includes a rear terminal mounting section at the rear of the cavity, and at least the longitudinal side wall section extends forward from one end or both ends of the rear section on one or both sides of the cavity . The metal casing has a top plate that substantially covers the dielectric casing. The side panels extend downwardly over the side wall sections of the casing. The side panels of the metal casing and/or the side wall segments of the body define the sides of the card receiving cavity. 10 One or more of the above-mentioned design features of the conventional memory card connector are shown in Japanese Patent Laid-Open No. 3299945, No. 3, 306, 395, and No. 3,325, 865, and Japanese Unexamined Patent Publication Nos. 2001-160458, 2001-167232, 2002-216905, and 10-187896 No. Numerous types of memory card connectors have been in use for many years and have design and/or dimensional parameters for receiving 15 (referred to herein and in the scope of the patent) conventional or normal size memory cards. In other words, these connectors receive a typical memory card that has been used for many years. However, with the increasing miniaturization or downsizing of small electronic devices, the memory card connector is also being miniaturized or downsized, resulting in the size reduction of the memory itself. Such reduced size memory will be referred to herein as a "compact size" memory card. For recently used small size memory cards, problems have arisen when inserting a small size memory card into a card receiving cavity of a card connector designed to receive a larger normal size memory card. Small size memory card is bent or bent 1267240 The contact part of the terminal in the normal memory card is bent. The terminals may even be shorted, causing severe damage to the circuits and appliances associated with the card connector. The small memory card may be blocked in the cavity of the normal memory card connector, so the small size memory card cannot be or is difficult to exit or remove from the normal card connector. This is to solve these problems in the normal size memory card connector to prevent the insertion of a small size memory card. [Certificate of the Invention] Summary of the Invention Therefore, there is a new and improved memory card connector having the above characteristics, wherein the connector is adapted to receive a normal size memory card but has a miscellaneous - A device that is fully inserted into a small-sized memory card. In an exemplary embodiment of the present invention, the memory card connector includes: a housing having a rear terminal mounting section, wherein the rear terminal mounting section mounts a plurality of terminals having contact portions, thereby engaging - normal size Suitable contacts on the card. The metal casing is embossed on the casing and combined to define a card joint (four) lining. The card is pure (four) multiplexed with a hole for inserting the opening before receiving the memory card 4 wherein the terminal mounting section is located behind the cavity. The spring member extends into the cavity at a position between the insertion opening and the contact portion of the terminal. The spring member is constructed such that the normal size is latched and the spring member is biased to the normal size memory card insertion cavity. The spring member is made to be engageable - a small size fe card and prevents the small size memory card from reaching the contact portion of the terminal. According to an embodiment of the invention, the spring member extends from a bottom wall of the housing to the moon body. The bump is made of a dielectric plastic material, and the spring member is made of spring 20 1267240 spring metal material and fixes the bottom wall of the domain body. In another embodiment, the spring member extends from a top wall of the metal casing into the cavity. The casing is formed by stamping a sheet of metal material, and the spring member is formed by punching out the wall of the casing. 5 10 In both embodiments, the elastomeric members are cantilevered into the cavity obliquely toward the rear of the cavity. The spring member includes a beveled arm portion and a portion located at the end of the beveled arm portion. The positive f-size needle feeds the oblique arm and biases the brake to the outside of the path of the normal size memory card insertion cavity. The small size memory card passes over the beveled arm and is blocked by the brakes. According to another aspect of the invention, the connector is attached to the same appliance having a card receiving passage that is coincident with the card receiving cavity. The passage has a mouth that is aligned with the front insertion opening of the cavity. The present invention contemplates that the mouth and the spring are framed in a small size, and the length of the card is inserted in the insertion direction. Other objects, features and advantages of the present invention will become apparent from the description of the appended claims.

A plurality of terminals 36 are mounted in a plurality of bead channels 38 in the rear terminal mounting section 30 of the housing. Each of the terminals has a contact portion 36a that extends from the cantilever into the cavity 27 to engage a suitable contact member of the normal size memory card 40 inserted into the cavity 27. A conventional push-push (pUSh-pUsh) type card ejecting mechanism 42 is mounted on the side wall section 32. It is known that the card ejecting mechanism constitutes a cam slider material, a cam pin 46 and a coil spring 48. In short, the cam slider 44 has a engaging projection 44a for engaging a leading edge 4 of the normal size memory card 4''. The coil spring 48 normally biases the cam slider in a direction toward the card insertion opening Μ. One end 46a of the cam pin 46 engages the side wall section 32, and an opposing 15缟4 of the cam pin engages within a heart shaped cam groove 50. The positive size brother card 40 is inserted into the card receiving cavity 27 until the card reaches its position of insertion (Fig. 5). The cam slider 44 moves with the memory card, ==_spring 48. When the pressure on the card is released, the exit mechanism biases the card back to a small extent in accordance with the cam grooves H. At the = terminal, the contact portion 36 of 36 transmits the second "push" system on the card, causing the exit mechanism to record at least part of the end of the card for the operator to grasp instead of taking off = The withdrawal mechanism may be dispensed with or replaced by a different type of organization without departing from the invention. 20 1267240 Referring to Figures 1 and 3, the metal casing 26 is generally rectangular and includes a top wall 27a that is generally used to define the top of the card receiving cavity 27. The metal casing has sidewalls 26a and 26b extending along opposite side edges of the top wall 26a and suspended therefrom at a right angle. The side wall 26a covers the exit mechanism 42 and the outside of the side wall section 32 of the housing. Sidewalls 26b define opposite sides of cavity 27. The side wall has a flange 26c that curves inwardly along its bottom edge. A plurality of open-ended, outwardly bent mounting tabs 26e provide means for mounting the connector to the underlying structure. Finally, a spring arm 2 of the metal casing is stamped to engage the top of the cam pin 46 of the ejecting mechanism 42 to bias the end point 4613 of the cam pin into the heart cam groove 50 of the mechanism. Referring to Figures 3 and 5, the memory card connector 22 is mounted with an appliance 52 having a card receiving passage 54 that coincides with the card receiving cavity of the connector. The passage 54 has an alignment chamber. Portion 54a of the front insertion opening 28 of the body, Figures 1 to 15 show various versions of the first embodiment of the invention, and Figures 16 to 20 show the version of the second embodiment of the invention. The numbers represent, as far as possible, similar elements in all versions of the two embodiments. Base 2 is understood above, and it is understood at this time that the present invention encompasses providing a portion 36am that is interposed between the opening and the opening 36 of the terminal 36. Positionally extending to at least the spring member 6〇 in the cavity 27. In the three versions of the first embodiment of the first to fifteenth versions, the 'spring member metal shell 26_ wall is applied downward=from the 16th to In a second embodiment of the 2G diagram, the magazine member extends upwardly from the & wall of the housing. In all versions of both embodiments, preferably the plurality of solid spring members are laterally separated in the insertion direction of the memory card. For example, Dijon 1267240 shows two punches in the top wall 26a of the metal casing 26 The spring member 60 is formed by the opening, JW. As shown in Fig. 3, the spring member 60 is cantilevered into the cavity 27 at an angle or a skewed direction toward the rear of the cavity. As shown in the following & A second embodiment of the present invention is also established. 5 Referring to Figure 4, each spring member 60 includes a beveled arm portion 64 that extends obliquely or downwardly into the cavity 27 at a corner. The position of a braking portion is ^ On one end of the horn arm. The braking portion is convex and defines a curved or convex surface 66a facing the insertion direction of the card. Heart tea photo 5 and 4, when - normal size When the memory card 4 is inserted into the cavity 10 27, a leading end 40a of the memory card will engage the beveled arm (Fig. 4) and bias the integral spring member upward. As the normal size memory card continues to be inserted The braking portion 66 of the spring member is biased upwardly out of the path of the normal size memory card insertion cavity without any interference with the spring member 60, as shown in Fig. 5. Now, Figures 3, 6 and 7 A sequence diagram showing a normal size memory card 70 inserted into the cavity 27 in the direction of the arrow A The memory card has a leading end 7 plus a tail 70b. The user pushes on the rear end 7〇b of the normal size memory card until the front $, 70a engages the braking portion 66 of the elastic member to prevent the memory card from being inserted. When the user releases the tail end 70b of the small-sized memory card, the spring member 60 can effectively bias or push the small-sized memory card out of the cavity 27 in the direction of the arrow b (Fig. 7). Figure 11 shows a second version of the spring member 60 formed by stamping the top wall 26a of the metal casing 26 and extending downwardly into the cavity. In the second version of Figures 8 through 11, the spring member is again included An angled arm portion 64 12 1267240. However, the end of the beveled arm is simply bent upward at a slight angle as 74, so that the end of the arm does not damage the top surface of the normal size memory card inserted into the cavity 27. In other words, the end of the beveled arm does not have a braking portion for the abutment of the leading end 7 of a small-sized memory card 7A, as in the first version. However, Figures 8 through 11 show a feature of the present invention included in all versions of both embodiments. Specifically, the distance between the mouth portion 54a of the passage 54 of the electric appliance 52 and the spring member 60 is approximately equal to the length of the small-sized memory card (i.e., between the leading end 70a and the trailing end 70b of the card). Therefore, when the small memory card is fully inserted into the position shown in the figure n, the tail end 70b of the card is flush with the mouth portion 54a and the user wire cannot insert a card into the cavity 27 in any way. When the person releases the card, the spring member 60 biases or pushes the card back into the cavity in the direction of arrow B. This phenomenon is performed by all versions of the two embodiments of the present invention. Therefore, since the card is pushed back 15 whenever the user inserts and releases the small memory card, the user can obviously find the wrong insertion of the small-sized memory card. In addition, the small-sized memory card cannot be fully inserted into the cavity in which the contact portion 36a of the terminal 36 cannot be removed or may be damaged. The third version of the first embodiment of the present invention shown in Figures 12 to 15 is similar to the first two versions in that the spring member 6'' has a beveled shape formed by punching the top wall 26a of the metal casing 2026. Arm 64. Further, the beveled arm portion is again cantilevered into the cavity 27 obliquely downward toward the rear of the cavity. In this third version of Figures U through 15, the braking portion 66 on the end of the beveled arm portion 64 provides a very positive blocking action for a small size memory card. Specifically, the braking portion 66 is in the shape of a hook to define a face-facing pocket of the memory card 13 1367240. The hook-shaped braking portion is joined to the beveled arm hook-shaped braking portion on a circular engaging portion 74. The extreme end of 66 is defined by a joint wall 76 of a particular length. When the Tianzheng size memory card is inserted into the cavity 27, the third version of the first embodiment of the present invention, which is not shown in Figures 12 to 15, the front end (Fig. 5) reconnects the beveled arm portion 64. And bias the spring member up. As the elastomeric member is biased upwards 'when the memory card is moved into its fully inserted position in the cavity, the memory card will ride along the circular joint 74. As described above, the engagement wall 76 has a - specific length' That is, the wall has a short length of the dog enough to move it 1 to the insertion path of the normal size memory card. :, ,;, and the figure 15 shows that it is inserted until the leading end of the card? The small-sized memory card 70 of the capsule portion 6 of the hook-shaped braking portion of the elastic member 60 is priced at a price. When the user releases the card, the spring member operates again to push the memory card back to the outside of the cavity. Figure 20 shows a second embodiment of the invention in which the spring member 6 is formed as a separate member and has a mounting foot 80 secured in one of the bores 82 of the bottom wall 34 of the housing 24 (Fig. 18). The member 6 is formed by stamping a spring metal material, wherein the foot 80 is inserted into the hole 82 of the plastic housing by press fitting. 2〇, particularly with reference to Fig. 18, the spring member 60 and the figures 12 to 15 The third version of the first embodiment is the same, with the difference that the beveled arm portion 64 faces Comparing the rear of the cavity at an angle or obliquely upward into the cavity 27. Comparing Fig. 18 of the second embodiment with Fig. 13 of the third version of the first embodiment, the only difference is that the second The spring member 60 of the embodiment extends into the cavity 27 in an upwardly beveled manner 14 1267240, and the spring member _ extends downwardly into the cavity at an angle. Therefore, similar numbers have been used to define: the moving portion 66 The bladder portion 66b, the joint portion 74, and the joint wall 76. 5 10 The operation of the second embodiment of Figs. 16 to 20 is the same as described above for the third version of the first embodiment shown in Figs. The same. The normal size memory card will engage the skewer 64 and bias the spring member downwards, wherein the bottom of the normal size memory card will follow the circle when the joint wall 76 moves beyond the insertion path of the normal size card. When the small-size memory card 70 is inserted into the cavity 27, the leading end 7〇a of the small-sized memory card will be blocked by the spring member-shaped braking portion 66, as shown in the figure (4). The invention may be embodied in other specific forms without departing from the spirit and scope of the invention. Therefore, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not limited to the details provided herein. 15 [Simplified Schematic] FIG. 1 is a top view of the memory card connector of the first embodiment; FIG. 2 is a perspective view of the insulating case of the first embodiment; FIG. 3 is a vertical cross-sectional view taken along line 3-3 of FIG. 20 with H from the (four) connector, and shows the _ small size memory card inserted into the connector; Figure 4 is a magnified segment of a region in the A circle in Figure 3; Figure 5 is similar to Figure 3, Where a normal size memory card is fully inserted into the connector; 15 1267240 Figures 6 and 7 are similar to Figure 3, showing the gradual phase of attempting to insert a small size memory card; Figures 8 through 11 are similar to the 3rd, 4th, and 6th, respectively.
