Description
本發明係關於卡插件(card connector),其安裝在攜帶式電話機、PDA(個人數字助理,personal digital assistants)、攜帶式數字音響唱機、遊戲機裝置、數碼照相機、信息終端設備等各種電子設備中使用之IC卡,進行IC卡和設備間的電連接。 The present invention relates to a card connector installed in various electronic devices such as a portable telephone, a PDA (personal digital assistants), a portable digital acoustic player, a game machine device, a digital camera, and an information terminal device. Use the IC card to make an electrical connection between the IC card and the device.
IC卡係於卡中埋入IC(集成電路,integrated circuit)。作為IC卡的種類,使用非易失性存儲器之存儲卡得到廣泛使用。存儲卡例如SD存儲卡作為可移動記錄介質,在攜帶式數字音響唱機、數碼照相機等使用。再有,在攜帶式電話機中,使用記錄利用者之固有ID號的SIM卡(用戶身份模塊卡,或智能卡,subscriber identity module card)。 The IC card is embedded in an IC (integrated circuit). As a type of IC card, a memory card using a nonvolatile memory is widely used. A memory card such as an SD memory card is used as a removable recording medium, and is used in a portable digital acoustic player, a digital camera, or the like. Further, in the portable telephone, a SIM card (user identity module card, or a subscriber identity module card) that records the unique ID number of the user is used.
IC卡相對卡插件設為***/拔取自如。例如,收納IC卡的卡盤等的IC卡藉由操作推壓銷能從殼體取出,或藉由所謂推入/推出方式將IC卡或安裝在附加器(adapter)的IC卡相對殼體***/拔取等,這為人們所公知。 The IC card is set to be inserted/extracted with respect to the card plug-in. For example, an IC card that accommodates a chuck of an IC card or the like can be taken out from the casing by operating the push pin, or the IC card or the IC card mounted on the adapter can be opposed to the casing by a so-called push-in/out mode. Insertion/extraction, etc., are well known.
在卡插件中,設有用於檢測IC卡是否相對卡插件安裝的開關。即,藉由與IC卡之***/拔取的移動連動進行切換之開關,檢測IC卡之***/拔取狀態,這樣的卡插件為人們所公知(參照專利文獻1)。開關的檢測結果用於對於卡之信號傳遞端子的信號傳遞用觸頭之帶電導線/非帶電導線狀態的切換控制等。 In the card insert, there is provided a switch for detecting whether the IC card is mounted relative to the card insert. In other words, such a card insert is known by a switch that is switched in conjunction with the movement of the insertion/extraction of the IC card, and the card insert is known (refer to Patent Document 1). The detection result of the switch is used for switching control of the state of the live conductor/non-charged conductor of the signal transmission contact of the signal transmission terminal of the card.
關於專利文獻1記載的開關,參照圖18、圖19、以及圖20說明。開關10包括分別由導電板構成的第一觸頭1和第二觸頭2,互相形成截面L字形狀,配置為使得其板面形成直角。第一觸頭1包括平板狀具有彈性的第一彈簧部11,在第一彈簧部11從一端側向著上方成為凸地彎曲延伸的操作部12,從操作部12前端平坦地延伸的接觸基部13,從接觸基 部13一側部向著上方傾斜的傾斜部14,以及從傾斜部14前端進一步向著上方折曲的由平面構成的接觸片15。接觸片15和第一彈簧部11形成為各平面互相正交。藉由與接觸基部13連接的傾斜部14和接觸片15構成第一接觸部。 The switch described in Patent Document 1 will be described with reference to FIGS. 18, 19, and 20. The switch 10 includes a first contact 1 and a second contact 2 each formed of a conductive plate, and is formed in an L-shaped cross section, and is disposed such that a plate surface thereof forms a right angle. The first contact 1 includes a first spring portion 11 having a flat plate shape, and the first spring portion 11 is an operation portion 12 that is convexly curved from the one end side toward the upper side, and the contact base portion 13 that extends flat from the front end of the operation portion 12 From the contact base The inclined portion 14 which is inclined toward the upper side of the portion 13 and the contact piece 15 which is formed by the flat surface which is bent upward from the front end of the inclined portion 14 are further provided. The contact piece 15 and the first spring portion 11 are formed such that the respective planes are orthogonal to each other. The first contact portion is constituted by the inclined portion 14 and the contact piece 15 connected to the contact base 13.
開關10之第二觸頭2包括配置為第二觸頭2的平面與第一觸頭1的平板面正交的第二彈簧部21,作為第二彈簧部21之前端的平面部22,以及從平面部22的上端朝外方折曲的導向片23。形成為傾斜部14的面和導向片23的面大致平行。藉由平面部22和導向片23構成第二接觸部。 The second contact 2 of the switch 10 includes a second spring portion 21 that is disposed such that the plane of the second contact 2 is orthogonal to the flat surface of the first contact 1, as the planar portion 22 of the front end of the second spring portion 21, and The guide piece 23 whose upper end of the flat portion 22 is bent outward is bent. The surface formed as the inclined portion 14 and the surface of the guide piece 23 are substantially parallel. The second contact portion is formed by the flat portion 22 and the guide piece 23.
若參照圖19以及圖20說明上述開關10之動作,則因IC卡***,第一觸頭1的操作部12如箭頭所示,朝著Y方向被推壓。在推壓以前狀態下,第一觸頭1和第二觸頭2為非接觸的常開狀態(開關斷開狀態)。 When the operation of the switch 10 is described with reference to FIGS. 19 and 20, the operation portion 12 of the first contact 1 is pressed in the Y direction as indicated by an arrow when the IC card is inserted. In the previous state of pushing, the first contact 1 and the second contact 2 are in a non-contact normally open state (switch open state).
由於推壓,第一觸頭1之傾斜部14和接觸片15與第二觸頭2之導向片23接觸,將第二觸頭2朝與推壓方向Y大致正交方向推壓,使其變位。X方向成為卡插件的殼體的厚度方向。隨著第一觸頭1朝Y方向變位,第一觸頭1的接觸部沿著導向片23的斜面逐漸朝下方移動,成為第一觸頭1的接觸片15與第二觸頭2的平面部22面接觸的狀態(即,開關完全接通的狀態)。 Due to the pressing, the inclined portion 14 of the first contact 1 and the contact piece 15 are in contact with the guide piece 23 of the second contact 2, and the second contact 2 is pressed in a direction substantially orthogonal to the pressing direction Y, thereby Variable Bit. The X direction becomes the thickness direction of the housing of the card insert. As the first contact 1 is displaced in the Y direction, the contact portion of the first contact 1 gradually moves downward along the slope of the guide piece 23, becoming the contact piece 15 of the first contact 1 and the second contact 2 The state in which the flat portion 22 is in surface contact (that is, the state in which the switch is fully turned on).
在專利文獻1記載的開關中,第二觸頭2的變位方向X相對推壓方向Y正交,不管第一觸頭1的變位量,第二觸頭2能保持一定的變位量。因此,即使第一觸頭1的變位量大場合,也能抑制第二觸頭2的變位量少。再有,第二觸頭2不會變位到一定變位量以上,能保持穩定的接觸。 In the switch described in Patent Document 1, the displacement direction X of the second contact 2 is orthogonal to the pressing direction Y, and the second contact 2 can maintain a certain amount of displacement irrespective of the amount of displacement of the first contact 1. . Therefore, even when the displacement amount of the first contact 1 is large, the amount of displacement of the second contact 2 can be suppressed to be small. Further, the second contact 2 is not displaced to a certain amount of displacement or more, and stable contact can be maintained.
[專利文獻1]日本專利第3635398號公報 [Patent Document 1] Japanese Patent No. 3635398
在專利文獻1記載的開關中,第二觸頭2的變位方向X是卡插件的厚度方向,第二觸頭2的變位量成為與卡插件的殼體厚度相對應。因此,使得殼體厚度薄場合,變位量變少,產生不能充分確保第一觸頭1和第二觸頭2需要的接觸壓力的問題。因此,卡插件的低高度化存在限度。再有,第一觸頭1之彈簧跨距之方向和第二觸頭2之彈簧跨距之方向在同一場所大致平行,因此,難以使得導向片23之傾斜面的長度長,當 第一觸頭1相對第二觸頭2登上時,第二觸頭2的負荷相對第一觸頭1急劇施加。其結果,因第一觸頭1和第二觸頭2的摩擦力產生第一觸頭1不回復到原來位置,或第一觸頭1產生扭曲,存在壓彎的危險。 In the switch described in Patent Document 1, the displacement direction X of the second contact 2 is the thickness direction of the card insert, and the displacement amount of the second contact 2 corresponds to the thickness of the casing of the card insert. Therefore, in the case where the thickness of the casing is made thin, the amount of displacement becomes small, and there arises a problem that the contact pressure required for the first contact 1 and the second contact 2 cannot be sufficiently ensured. Therefore, there is a limit to the low height of the card insert. Further, the direction of the spring span of the first contact 1 and the direction of the spring span of the second contact 2 are substantially parallel at the same place, and therefore, it is difficult to make the length of the inclined surface of the guide piece 23 long. When the first contact 1 is mounted with respect to the second contact 2, the load of the second contact 2 is sharply applied with respect to the first contact 1. As a result, the first contact 1 does not return to the original position due to the frictional force of the first contact 1 and the second contact 2, or the first contact 1 is distorted, and there is a risk of bending.
本發明係鑑於這種以往技術所存在的問題而提出來的,其目的在於,提供能解決以往開關具有的上述問題的卡插件。 The present invention has been made in view of such problems in the prior art, and an object thereof is to provide a card insert that can solve the above problems of the conventional switch.
為了解決上述課題,本發明的卡插件包括:殼體,***卡狀體或載置卡狀體的盤,具有能收納卡狀體或盤的扁平的收納空間;板簧狀的第一觸頭,一端側固定在殼體,另一端側因與***收納空間的卡狀體或盤相接而撓曲;縫隙,另一端開放,從第一觸頭的另一端側向著一端側形成,因在第一觸頭的板面方向施加的力,該縫隙寬度變狹;以及板狀的第二觸頭,一端側固定在殼體;其中,藉由第一觸頭被賦能,第一觸頭的另一端側的端面朝板面方向撓曲,與第二觸頭接觸,進行滑動。 In order to solve the above problems, the card insert of the present invention includes a case, a card inserted into the card body or a disk on which the card body is placed, and a flat storage space capable of accommodating the card body or the disk; the first contact of the leaf spring shape One end side is fixed to the casing, and the other end side is flexed by being in contact with the card body or the disk inserted into the storage space; the slit is open at the other end, and is formed from the other end side of the first contact toward the one end side, because a force applied by a plate surface direction of the first contact, the slit width is narrowed; and a plate-shaped second contact fixed to the housing at one end side; wherein the first contact is energized by the first contact The end surface on the other end side is bent toward the board surface, comes into contact with the second contact, and slides.
按照本發明,在卡收納空間內第一觸頭能撓曲,因此,即使卡插件的殼體低高度化場合,也能確保必要的載荷。再有,能使得第一觸頭和第二觸頭接觸後的摩擦力伴隨第一觸頭移動逐漸變大,能避免如以往構成那樣第二觸頭的載荷對於第一觸頭急劇施加而引起的問題。即,能避免因第一觸頭與第二觸頭的摩擦力不能回復到原位置的問題,以及第一觸頭產生扭曲引起彎曲等問題。 According to the present invention, since the first contact can be flexed in the card housing space, the necessary load can be secured even when the housing of the card insert is lowered in height. Further, the frictional force after the contact between the first contact and the second contact can be gradually increased with the movement of the first contact, and the load of the second contact can be prevented from being sharply applied to the first contact as in the conventional configuration. The problem. That is, it is possible to avoid the problem that the friction of the first contact and the second contact cannot be restored to the original position, and the problem that the first contact is distorted to cause bending.

下面參照附圖說明本發明的實施形態。以下說明的第一實施 形態和第二實施形態是本發明的合適的具體例子,雖然對構成要素,種類,組合,形狀,相對配置等作了各種技術限定,但是,這些僅僅是例舉,本發明並不局限於此。 Embodiments of the present invention will be described below with reference to the drawings. The first implementation described below The form and the second embodiment are suitable specific examples of the present invention, and various technical limitations are imposed on constituent elements, types, combinations, shapes, relative arrangements, and the like, but these are merely examples, and the present invention is not limited thereto. .
[1.第一實施形態] [1. First embodiment]
說明根據本發明第一實施形態的卡插件。 A card insert according to a first embodiment of the present invention will be described.
圖1是在與IC卡的***/拔取方向一致的面切斷卡插件的截面圖。如圖1所示,卡插件包括絕緣板31,以及與絕緣板31對向設置的屏蔽罩(shield cover)32。由絕緣板31和屏蔽罩32構成殼體。絕緣板31是例如液晶聚合物的成型品。屏蔽罩32是將金屬例如不銹鋼折曲加工而成。從殼體的一端面的卡***口33,將IC卡例如SIM卡***形成在殼體內部的卡收納凹部。在本說明書中,將卡***口33側稱為前或前面,卡***口的相反側稱為後或背面,從卡***口看,將右側的面稱為右或右側面,左側的面稱為左或左側面。 Fig. 1 is a cross-sectional view showing the card insert cut in a plane coinciding with the insertion/extraction direction of the IC card. As shown in FIG. 1, the card insert includes an insulating plate 31, and a shield cover 32 disposed opposite the insulating plate 31. The casing is constituted by the insulating plate 31 and the shield case 32. The insulating sheet 31 is a molded article of, for example, a liquid crystal polymer. The shield case 32 is formed by bending a metal such as stainless steel. An IC card such as a SIM card is inserted into a card housing recess formed inside the casing from the card insertion opening 33 at one end surface of the casing. In the present specification, the side of the card insertion opening 33 is referred to as the front or the front side, and the opposite side of the card insertion opening is referred to as the rear or back side. When viewed from the card insertion opening, the right side surface is referred to as the right or right side surface, and the left side surface is referred to as the right side or the right side surface. For the left or left side.
作為SIM卡,有比標準SIM卡小的形狀的微SIM卡,或比微SIM卡小的毫微SIM卡。所述SIM卡尺寸不同,但插腳配置等物理特性互相相同。本發明對於任何SIM卡均能適用。再有,對於SD存儲卡等其它IC卡也能適用。再有,即使將尺寸不同的IC卡安裝在附加器、與標準IC卡同樣使用場合也能適用本發明。再有,即使卡插件設有盤、將IC卡載置在盤上使用場合也能適用本發明。卡狀體意味IC卡或附加器。 As a SIM card, there is a micro SIM card having a smaller shape than a standard SIM card, or a nano SIM card smaller than a micro SIM card. The SIM cards are different in size, but the physical characteristics such as the pin configuration are the same as each other. The invention is applicable to any SIM card. Further, it is also applicable to other IC cards such as an SD memory card. Further, the present invention can be applied even when an IC card having a different size is attached to an adder and used in the same manner as a standard IC card. Further, the present invention can be applied even when a card insert is provided with a disk and the IC card is placed on the disk. The card body means an IC card or an adder.
圖2和圖3是除去屏蔽罩32狀態的絕緣板31的立體圖。如圖2及圖3所示,絕緣板31一體形成右側壁34a、左側壁34b、後壁34c、以及與卡***口33鄰接的前壁34d,形成能收納IC卡的收納空間。屏蔽罩32安裝在絕緣板31上,用焊接等固定。 2 and 3 are perspective views of the insulating plate 31 in a state in which the shield case 32 is removed. As shown in FIGS. 2 and 3, the insulating plate 31 integrally forms a right side wall 34a, a left side wall 34b, a rear wall 34c, and a front wall 34d adjacent to the card insertion opening 33, thereby forming a storage space in which an IC card can be housed. The shield case 32 is attached to the insulating plate 31 and fixed by welding or the like.
在SIM卡上,藉由鍍金形成8個插腳(也稱為電極,端子,焊接點(pad)),各插腳分配為數據輸入/輸出端子,接地端子,電源輸入端子等。例如,在攜帶式電話機用的SIM卡場合,實際上在8個插腳內使用6個插腳。與SIM卡的插腳配置對應,在絕緣板31上,分別設有6個觸頭35a,35b,35c,35d,35e,35f。當沒有必要個別區分觸頭場合,簡稱為觸頭35。 On the SIM card, eight pins (also referred to as electrodes, terminals, pads) are formed by gold plating, and each pin is assigned as a data input/output terminal, a ground terminal, a power input terminal, and the like. For example, in the case of a SIM card for a portable telephone, six pins are actually used in eight pins. Corresponding to the pin configuration of the SIM card, six contacts 35a, 35b, 35c, 35d, 35e, 35f are respectively disposed on the insulating plate 31. When it is not necessary to separately distinguish the contacts, it is simply referred to as the contact 35.
觸頭35係例如由磷青銅構成的彈簧接點,從殼體底面切 起,前端設為與SIM卡的插腳的接觸面。觸頭35的另一端導出到絕緣板31的下側,面對形成在絕緣板31的開口36。觸頭35的另一端與殼體設置的印製配線基板上的配線圖形錫焊,***到卡插件的IC卡和印製配線基板之間電連接。觸頭35藉由例如鑲嵌成型設在絕緣板31。觸頭35以外的其它金屬零件也同樣藉由鑲嵌成型相對絕緣板31***。但是,後述滑塊41,螺旋彈簧42,導向銷43等零件設為與絕緣板31不同的另外零件。 The contact 35 is, for example, a spring contact made of phosphor bronze, cut from the bottom surface of the housing The front end is set to the contact surface with the pins of the SIM card. The other end of the contact 35 is led to the lower side of the insulating plate 31, facing the opening 36 formed in the insulating plate 31. The other end of the contact 35 is soldered to the wiring pattern on the printed wiring board provided in the casing, and is electrically connected between the IC card inserted into the card insert and the printed wiring board. The contact 35 is provided on the insulating plate 31 by, for example, insert molding. Metal parts other than the contacts 35 are also inserted into the insulating plate 31 by insert molding. However, components such as the slider 41, the coil spring 42, and the guide pin 43 which will be described later are different from the insulating plate 31.
本發明的第一實施形態藉由推入/推出方式***/拔取IC 卡。即,在推入/推出方式中,藉由反復同一方向的操作力,實行壓入動作和拉出動作。具體地說,使用心形凸輪式的推入/推出機構。本發明並不局限於推入/推出方式,即使對於***IC卡鎖定、操作鎖定銷使得IC卡從卡插件脫離結構的卡插件,也能適用。 The first embodiment of the present invention inserts/extracts an IC by push-in/out mode card. In other words, in the push/pull method, the press-in operation and the pull-out operation are performed by repeating the operation force in the same direction. Specifically, a heart-shaped cam type push-in/out mechanism is used. The present invention is not limited to the push-in/out mode, and can be applied even to a card insert in which the IC card is locked and the lock pin is operated so that the IC card is detached from the card insert.
如圖2至圖6所示,與IC卡一起往復移動的金屬制、例如 不銹鋼製的滑塊41配置在卡收納空間內。滑塊41的卡***口側的一端由螺旋彈簧42常時朝推出方向賦能。螺旋彈簧42配置在絕緣板31的沿右側壁34a配設的金屬制的彈簧收納套內。滑塊41的另一端大致彎曲成直角,使得IC卡的前端的相接部與滑塊41的前端相接。若IC卡***卡***空間,則反抗螺旋彈簧42的賦能方向,滑塊41和IC卡一體朝後方滑動。 As shown in FIGS. 2 to 6, a metal made to reciprocate with the IC card, for example, The slider 41 made of stainless steel is disposed in the card housing space. One end of the slider 41 on the card insertion opening side is energized by the coil spring 42 in the ejecting direction. The coil spring 42 is disposed in a metal spring housing that is disposed along the right side wall 34a of the insulating plate 31. The other end of the slider 41 is bent substantially at a right angle so that the abutting portion of the front end of the IC card is in contact with the front end of the slider 41. When the IC card is inserted into the card insertion space, the slider 41 and the IC card are integrally slid rearward in opposition to the energizing direction of the coil spring 42.
相對形成在滑塊41的孔,導向銷43的一端迴轉自如地插 入。即,導向銷43一端形成彎曲,一端***滑塊41的支持孔,構成導向銷43的迴轉中心軸。導向銷43的迴轉自如的另一端彎曲,彎曲的另一端的前端***銷導向槽44內。銷導向槽44形成在絕緣板31上。 Relatively formed in the hole of the slider 41, one end of the guide pin 43 is freely inserted In. That is, one end of the guide pin 43 is bent, and one end is inserted into the support hole of the slider 41 to constitute the center axis of rotation of the guide pin 43. The other end of the guide pin 43 is freely rotatable, and the front end of the other end of the bend is inserted into the pin guide groove 44.

In other words, the switch 51 that is switched in conjunction with the movement of the insertion/extraction direction of the IC card detects the insertion/extraction state of the IC card 50, and the detection result is used for switching control of the charged/non-charged state of the signal transmission contact 35. Wait.
參照圖8、圖9、圖10A、以及圖10B詳細說明開關51。開 關51由第一觸頭52以及第二觸頭53構成。第一觸頭52和第二觸頭53都是由磷青銅構成的彈簧接點,藉由鑲嵌成型設在絕緣板31的卡收納凹部的後方。與第一觸頭52電連接的端子以及與第二觸頭53電連接的端子導出到絕緣板31的側面或底面,與外部的印製配線基板連接。 The switch 51 will be described in detail with reference to FIGS. 8 , 9 , 10A, and 10B. open The closing 51 is composed of a first contact 52 and a second contact 53. The first contact 52 and the second contact 53 are spring contacts made of phosphor bronze, and are provided in the rear of the card housing recess of the insulating plate 31 by insert molding. The terminal electrically connected to the first contact 52 and the terminal electrically connected to the second contact 53 are led out to the side surface or the bottom surface of the insulating plate 31, and are connected to the external printed wiring board.
第一觸頭52是具有與IC卡50的***/拔取方向大致正交的 板面的板簧,其基部在卡收納凹部的後壁34c的附近藉由鑲嵌成型固定在絕緣板31。延長第一觸頭52的板狀的彈簧部54的前端,向著卡***口側彈性***,設有半圓狀的突出部。再有,彎曲成使得前端與卡***/拔取方向平行。半圓狀的突出部是與IC卡50的前端面相接的動作部55。 The first contact 52 is substantially orthogonal to the insertion/extraction direction of the IC card 50. The leaf spring of the plate surface is fixed to the insulating plate 31 by insert molding in the vicinity of the rear wall 34c of the card housing recess. The front end of the plate-shaped spring portion 54 of the first contact 52 is extended, and is elastically raised toward the card insertion opening side, and a semicircular projection is provided. Further, the bending is such that the front end is parallel to the card insertion/extraction direction. The semicircular protruding portion is an operation portion 55 that is in contact with the front end surface of the IC card 50.
第一觸頭52包括細帶狀的縫隙56,其另一端開放,從第一 觸頭52的另一端側向一端側延伸。例如,縫隙56形成為從開放端直到超過動作部55程度的位置。縫隙56形成在第一觸頭52的寬度的中間位置,設為從第一觸頭52的另一端側向著一端側開口寬度逐漸變小的形狀。第一觸頭52的另一端的下側端面設為與第二觸頭53接觸的接觸部57。接觸部57具有沿著第二觸頭53的傾斜接觸面的傾斜。 The first contact 52 includes a thin strip-shaped slit 56, the other end of which is open, from the first The other end side of the contact 52 extends toward one end side. For example, the slit 56 is formed to a position from the open end to the extent beyond the action portion 55. The slit 56 is formed at an intermediate position of the width of the first contact 52, and has a shape in which the opening width gradually decreases from the other end side of the first contact 52 toward the one end side. The lower end surface of the other end of the first contact 52 is provided as a contact portion 57 that is in contact with the second contact 53. The contact portion 57 has an inclination along the inclined contact surface of the second contact 53.
與絕緣板31的後壁34c相接,形成窗部58,設有板狀彈簧, 其具有與卡的***/拔取方向平行的板面,從後壁34c向著窗部58突出。板狀彈簧的中央部切起,設為第二觸頭53。形成從第一觸頭52的彈簧部54的下端面朝下方突出的突起59,突起59與窗部58的角部60相接,限制使得第一觸頭52不打開到必要以上。 It is in contact with the rear wall 34c of the insulating plate 31 to form a window portion 58 provided with a plate spring. It has a plate surface parallel to the insertion/extraction direction of the card, and protrudes from the rear wall 34c toward the window portion 58. The central portion of the plate spring is cut and set as the second contact 53. A projection 59 projecting downward from the lower end surface of the spring portion 54 of the first contact 52 is formed, and the projection 59 is in contact with the corner portion 60 of the window portion 58 to restrict the first contact 52 from being opened more than necessary.
第二觸頭53是具有傾斜面的切起片,所述傾斜面從卡*** 口側的基部向著後壁34c側的自由端上升。第一觸頭52的接觸部57設為能相對傾斜面接觸。再有,傾斜不同,使得第二觸頭53的自由端附近更向上側。這是為了在第一觸頭52的接觸部57沿第二觸頭53的傾斜面滑動場合,在第二觸頭53的傾斜面的前端附近,使其產生更大的接觸壓力,使得第一觸頭52和第二觸頭53的接觸穩定。 The second contact 53 is a chopped piece having an inclined surface that is inserted from the card The base on the side of the mouth rises toward the free end on the side of the rear wall 34c. The contact portion 57 of the first contact 52 is set to be in contact with the inclined surface. Further, the inclination is different so that the vicinity of the free end of the second contact 53 is further upward. This is to cause a larger contact pressure near the front end of the inclined surface of the second contact 53 when the contact portion 57 of the first contact 52 slides along the inclined surface of the second contact 53, so that the first contact pressure is made. The contact between the contact 52 and the second contact 53 is stable.
換言之,板狀之第二觸頭之一端側(後壁34c側)固定於上述 殼體。第二觸頭53具有傾斜面,從上述第二觸頭的另一端側向著上述一端側上升,第一觸頭52的另一端側的端面朝板面方向撓曲,與該傾斜面接觸,進行滑動。 In other words, one end side of the second contact of the plate shape (the side of the rear wall 34c) is fixed to the above case. The second contact 53 has an inclined surface, and rises from the other end side of the second contact toward the one end side, and the end surface of the other end side of the first contact 52 is deflected toward the plate surface direction, and is in contact with the inclined surface. Slide it.
圖11A放大表示IC卡50的安裝沒有結束的狀態,即,卡推 出狀態。在卡推出狀態下,第一觸頭52和第二觸頭53是非接觸狀態,為開關斷開狀態(常開)。接著,若推入IC卡50,成為安裝結束狀態,則如圖11B所示,IC卡50的相接部推壓第一觸頭52的動作部,第一觸頭52和第二觸頭53接觸,成為開關接通狀態。即,第一觸頭52的接觸部57與第二觸頭53的傾斜面彈性接觸。 11A is an enlarged view showing a state in which the mounting of the IC card 50 is not completed, that is, a card push Out of state. In the card push-out state, the first contact 52 and the second contact 53 are in a non-contact state, and are in a switch-off state (normally open). When the IC card 50 is pushed in and the mounting end state is reached, as shown in FIG. 11B, the contact portion of the IC card 50 pushes the operating portion of the first contact 52, and the first contact 52 and the second contact 53 are pressed. Contact, become the switch on state. That is, the contact portion 57 of the first contact 52 is in elastic contact with the inclined surface of the second contact 53.
***IC卡50,由IC卡50推壓第一觸頭52場合的開關51 的狀態變化過程表示在圖12A及圖12B。圖12A及圖12B表示由IC卡50的相接部推壓第一觸頭52的動作部、順序變化為狀態Sa、Sb、Sc的狀態。 The switch 51 in which the IC card 50 is inserted and the first contact 52 is pushed by the IC card 50 The state change process is shown in Figs. 12A and 12B. 12A and 12B show a state in which the operation portion of the first contact 52 is pressed by the contact portion of the IC card 50, and the states are changed to the states Sa, Sb, and Sc.
狀態Sa是沒有發生IC卡50的推壓動作的狀態,表示第一觸頭52和第二觸頭53非接觸的狀態。狀態Sb表示雖然IC卡50的相接部推壓第一觸頭52的動作部,但第一觸頭52和第二觸頭53還是非接觸狀態。狀態Sc表示推入IC卡50安裝結束、第一觸頭52和第二觸頭53接觸的接觸狀態。在狀態Sa及狀態Sb中,開關51斷開,在狀態Sc中,開關51接通。 The state Sa is a state in which the pressing operation of the IC card 50 does not occur, and indicates a state in which the first contact 52 and the second contact 53 are not in contact with each other. The state Sb indicates that the first contact 52 and the second contact 53 are in a non-contact state although the contact portion of the IC card 50 pushes the operation portion of the first contact 52. The state Sc indicates the contact state in which the mounting of the IC card 50 is completed and the first contact 52 and the second contact 53 are in contact. In the state Sa and the state Sb, the switch 51 is turned off, and in the state Sc, the switch 51 is turned on.
在狀態Sc中,第一觸頭52的彈簧跨距方向和第二觸頭53的彈簧跨距方向交叉成大致直角。所謂彈簧跨距是指板簧的載荷支持點間的距離,彈簧跨距方向是指連接載荷支持點間的方向。在第一觸頭52場合,連接基部的固定位置和可動的前端的方向成為彈簧跨距方向。在第二觸頭53場合,連接切起的基部和切起片的前端的方向成為彈簧跨距方向。 In the state Sc, the spring span direction of the first contact 52 and the spring span direction of the second contact 53 intersect at substantially right angles. The so-called spring span refers to the distance between the load support points of the leaf spring, and the spring span direction refers to the direction between the connection load support points. In the case of the first contact 52, the fixed position of the connection base and the direction of the movable front end become the spring span direction. In the case of the second contact 53, the direction of connecting the cut base and the front end of the cut and raised piece becomes the spring span direction.
在上述狀態的變化過程中,圖1213表示第一觸頭52的動作。在狀態Sa及狀態Sb中,第一觸頭52和第二觸頭53非接觸,因此,包含第一觸頭52的縫隙56的前端部不變化。在從狀態Sb向狀態Sc的變化過程中,第一觸頭52的接觸部57與第二觸頭53的傾斜面接觸,將第二觸頭53的傾斜面逐漸朝下側壓入。這種場合,對於第一觸頭52的接觸部57施加朝上方向推壓的力,由夾著縫隙56的下側片和上側片構成的彈簧動作,使得縫隙56寬度變小。 During the change of the above state, FIG. 1213 shows the action of the first contact 52. In the state Sa and the state Sb, the first contact 52 and the second contact 53 are not in contact, and therefore, the front end portion of the slit 56 including the first contact 52 does not change. During the change from the state Sb to the state Sc, the contact portion 57 of the first contact 52 comes into contact with the inclined surface of the second contact 53, and the inclined surface of the second contact 53 is gradually pressed inward. In this case, the contact portion 57 of the first contact 52 is biased in the upward direction, and the spring formed by the lower side piece and the upper side piece sandwiching the slit 56 is moved to make the width of the slit 56 small.
由第一觸頭52的夾著縫隙56的下側片和上側片構成的彈簧的回复力在第一觸頭52與第二觸頭53接觸後沿傾斜面滑動的過程中逐漸變強。因此,第一觸頭52和第二觸頭53的接觸後的接觸壓力(摩擦力)伴隨第一觸頭52的移動逐漸變大。藉由這樣的作用,能防止如上述以往開關那樣的觸頭的接觸不良或扭曲引起彎曲。 The restoring force of the spring constituted by the lower side piece and the upper side piece of the first contact 52 sandwiching the slit 56 gradually becomes stronger as it slides along the inclined surface after the first contact 52 contacts the second contact 53. Therefore, the contact pressure (frictional force) after the contact of the first contact 52 and the second contact 53 gradually becomes larger as the movement of the first contact 52 is increased. By such an action, it is possible to prevent the contact failure or the distortion of the contact such as the conventional switch described above from causing the bending.
再有,在本發明的第一實施形態中,能藉由縫隙56的下側的板簧部分的寬度或縫隙56的長方向的長度設定所希望的接觸壓力。即,下側的板簧部分的寬度越大,彈簧發生的載荷越大,縫隙56的長度越短,彈簧發生的載荷越大。 Further, in the first embodiment of the present invention, the desired contact pressure can be set by the width of the lower leaf spring portion of the slit 56 or the length of the slit 56 in the longitudinal direction. That is, the larger the width of the lower leaf spring portion, the larger the load generated by the spring, and the shorter the length of the slit 56, the larger the load generated by the spring.
[2.第一實施形態的變形例] [2. Modification of the first embodiment]
圖13A及圖13B表示本發明第一實施形態的變形例。在第一觸頭52的縫隙56的上側的動作部55a和下側的動作部55b之間,設有***/拔取方向 的階梯差61。例如,與第二觸頭53接觸的下側的動作部55b設為與上述第一實施形態的動作部55的位置相同。藉由彎曲第一觸頭52,上側的動作部55a設為更靠近IC卡的***口側的位置,形成階梯差61。 13A and 13B show a modification of the first embodiment of the present invention. An insertion/extraction direction is provided between the upper operation portion 55a of the slit 56 of the first contact 52 and the lower operation portion 55b. The step difference is 61. For example, the lower operation portion 55b that is in contact with the second contact 53 is set to be the same as the position of the operation portion 55 of the first embodiment. By bending the first contact 52, the upper operating portion 55a is placed closer to the insertion port side of the IC card, and a step 61 is formed.
即,上述第一觸頭52的位於上述縫隙56的上下的部分在與彈簧跨距大致垂直的方向具有階梯差,在上述位於上下的部分中,沒有與上述第二觸頭53接觸的部分與上述卡狀體50或上述盤相接。 That is, the upper and lower portions of the first contact 52 located at the slit 56 have a step in a direction substantially perpendicular to the spring span, and in the upper and lower portions, there is no portion in contact with the second contact 53 and The card body 50 or the disk is in contact with each other.
在該變形例中,能藉由階梯差61的大小調整開關51的接通/斷開的時間。即,若增大階梯差61,則當***IC卡50時,第一觸頭52的開始動作的時間變早,能提早開關接通時間。當拔取IC卡50場合,若增大階梯差61,則第一觸頭52的開始動作的時間變遲,能推遲開關斷開時間。 In this modification, the time during which the switch 51 is turned on/off can be adjusted by the size of the step 61. That is, when the step 61 is increased, when the IC card 50 is inserted, the time at which the first contact 52 starts to operate becomes earlier, and the switch-on time can be advanced. When the IC card 50 is taken out, if the step 61 is increased, the time until the start of the first contact 52 is delayed, and the switch off time can be delayed.
[3.第二實施形態] [3. Second embodiment]
參照圖14至圖17說明本發明第二實施形態。第二實施形態的開關71如圖14所示,由第一觸頭72及第二觸頭73構成。第一觸頭72是具有與IC卡70的***/拔取方向大致正交的板面的板簧,其基部在卡收納凹部的後壁附近藉由鑲嵌成型固定在絕緣板31。第一觸頭72設為使得板面與***/拔取方向正交的板簧的彈簧部74的自由端朝著卡***口側的相反側大致180°彎曲返回的形狀。 A second embodiment of the present invention will be described with reference to Figs. 14 to 17 .

A slit 76 is formed near the free end of the bending return. The lower side piece and the upper side piece of the slit 76 are extended downward at substantially right angles, and are bent inward by the extended end to form contact portions 77a and 77b which can come into contact with the second contact 73. Thus, by bending the leaf spring back to form a double-ended front end portion, an action portion 75 that is in contact with the front end of the IC card 70 can be provided at one end portion, and two slits 76 can be formed at the other front end portion. Contact portions 77a and 77b.

The above figure shows the state in which the shield case is removed. The casing is formed by the insulating plate 81 and the shield case. The card insert is provided with a slider 85 that is energized by the coil spring 84 in the discharge direction.
對於滑塊85形成心形凸輪86的銷導向槽87。導向銷88的前端部相對銷導向槽87滑動自如地***。導向銷88的基部迴轉自如地***形成在絕緣板81的凹部。藉由心形凸輪86構成鎖定機構,構成推入/推出方式的卡插件。 The pin guide groove 87 of the heart cam 86 is formed for the slider 85. The front end portion of the guide pin 88 is slidably inserted into the pin guide groove 87. The base of the guide pin 88 is rotatably inserted into a recess formed in the insulating plate 81. The card-shaped cam 86 constitutes a locking mechanism, and constitutes a card insertion/ejection type card insert.
再有,在滑塊85的卡***側設有板簧89。板簧89前端部彎曲成U字狀,使得板簧89的凸部朝卡收納凹部突出。板簧89的凸部進入形成在IC卡70的側面的卡合用凹部90。 Further, a leaf spring 89 is provided on the card insertion side of the slider 85.

The convex portion of the leaf spring 89 enters the engagement recess 90 formed on the side surface of the IC card 70.
開關71設在上述卡插件的卡收納空間內。開關71在IC卡70非***狀態或IC卡70沒有推入的彈出狀態(圖15B)下,第一觸頭72和第二觸頭73不接觸,為開關斷開狀態。如圖16B和圖17所示,若IC卡70相對卡插件推入,安裝結束,則第一觸頭72和第二觸頭73接觸,為開關接通狀態。這樣,檢測IC卡70的***/拔取狀態,根據檢測結果使用於信號傳遞用觸頭82的帶電線/非帶電線狀態的切換控制等。第二實施形態能具有與第一實施形態同樣的效果。並且,第二實施形態具有二個接觸部77a和77b,因此,能實現可靠的觸頭接觸,且能提高觸頭的自身清潔效果。 The switch 71 is provided in the card housing space of the card insert. The switch 71 is in a non-inserted state of the IC card 70 or an ejected state in which the IC card 70 is not pushed (FIG. 15B), and the first contact 72 and the second contact 73 are not in contact, and are in a switch-off state. As shown in FIG. 16B and FIG. 17, when the IC card 70 is pushed in with respect to the card insert, the mounting is completed, and the first contact 72 and the second contact 73 are in contact with each other, and the switch is in an ON state. In this way, the insertion/extraction state of the IC card 70 is detected, and the switching control of the wired/non-wired state of the signal transmission contact 82 is used based on the detection result. The second embodiment can have the same effects as those of the first embodiment. Further, the second embodiment has the two contact portions 77a and 77b, so that reliable contact contact can be achieved and the self-cleaning effect of the contact can be improved.
[4.變形例] [4. Modifications]
上述具體說明本發明的實施例,但是,本發明並不限定於上述各實施形態,能根據本發明技術思想進行各種變形。例如,在上述實施形態中,開關設在殼體裡側,第一觸頭設為在與卡狀體或盤的***/拔取方向大致正交方向具有板面。但是,也可以配設為在殼體側壁附近第一觸頭的板面具有與***/拔取方向大致相同方向,當卡狀體或盤***場合,第一觸頭朝著與***/拔取方向大致正交方向撓曲。 Although the embodiments of the present invention have been specifically described above, the present invention is not limited to the above embodiments, and various modifications can be made in accordance with the technical idea of the present invention. For example, in the above embodiment, the switch is provided on the inner side of the casing, and the first contact has a plate surface in a direction substantially orthogonal to the insertion/extraction direction of the card body or the disk. However, it is also possible to arrange that the plate surface of the first contact near the side wall of the casing has substantially the same direction as the insertion/extraction direction, and when the card body or the disk is inserted, the first contact is oriented substantially in the direction of insertion/extraction. Flexing in orthogonal directions.
例如,在上述第一實施形態及第二實施形態中,說明常開式 的開關,但是,開關也可以是常閉式。再有,也可以將本發明適用於推入/推出方式以外的卡插件。具體地說,即使對於不使用由心形凸輪所構成的鎖定機構的卡插件也能適用本發明。在上述實施形態中列舉的構成、方法、工序、形狀、材料、以及數值等都不過是舉例,可以根據需要使用與其不同的構成、方法、工序、形狀、材料、以及數值等。 For example, in the first embodiment and the second embodiment described above, the normally open type is described. The switch, however, can also be normally closed. Further, the present invention can also be applied to a card insert other than the push/pull method. Specifically, the present invention can be applied to a card insert that does not use a locking mechanism composed of a heart-shaped cam. The configurations, methods, steps, shapes, materials, numerical values, and the like listed in the above embodiments are merely examples, and different configurations, methods, steps, shapes, materials, numerical values, and the like may be used as needed.
