本發明係關於一種具有用於檢測卡之***及抽出的檢測開關之卡連接器。 The present invention relates to a card connector having a detecting switch for detecting insertion and withdrawal of a card.
過去，例如在容納記憶卡或SIM(加入者識別模組)卡等之卡的卡連接器等中，通常為具有用於檢測其卡之***及抽出的檢測開關者。 In the past, for example, in a card connector or the like that accommodates a card such as a memory card or a SIM (Joiner Identification Module) card, it is generally provided with a detection switch for detecting insertion and withdrawal of the card.
過去此種卡連接器之一例，例如已知為第十二圖及第十三圖所示者。第十二圖顯示過去之卡連接器的一例，(A)係拆下護蓋之狀態的斜視圖，(B)係重要部分放大斜視圖。第十三圖顯示設於第十二圖所示之卡連接器中的檢測開關之動作，(A)係卡抵接於第一觸頭的滑動接觸部之前的狀態剖面圖，(B)係卡已抵接於第一觸頭之滑動接觸部的狀態剖面圖，(C)係卡已搭乘在第一觸頭之滑動接觸部上的狀態剖面圖，(D)係卡抵接於第二觸頭之抵接部，而接點部從第一觸頭之接點部離開的狀態剖面圖。 An example of such a card connector in the past is known, for example, as shown in the twelfth and thirteenth drawings. Fig. 12 shows an example of a conventional card connector, (A) is a perspective view showing a state in which the cover is removed, and (B) is an enlarged perspective view of an important part. Fig. 13 is a view showing the operation of the detecting switch provided in the card connector shown in Fig. 12, and (A) a sectional view of the state before the card contacts the sliding contact portion of the first contact, (B) A cross-sectional view of the state in which the card has abutted against the sliding contact portion of the first contact, (C) a cross-sectional view of the state in which the card has been mounted on the sliding contact portion of the first contact, and (D) the card is abutted against the second A cross-sectional view of the contact portion of the contact, and the contact portion is separated from the contact portion of the first contact.
第十二圖(A)、(B)所示之卡連接器101，係卡140向箭頭A方向***並且向箭頭B方向抽出者，且具備容納卡140之塞槽(Housing)110。塞槽110中設有與設於卡140背面之複數個導電焊墊141接觸的複數個觸頭120。 In the card connector 101 shown in FIGS. 12A and (B), the card 140 is inserted in the direction of the arrow A and is drawn in the direction of the arrow B, and has a housing 110 for accommodating the card 140. A plurality of contacts 120 are formed in the plug slot 110 in contact with a plurality of conductive pads 141 disposed on the back surface of the card 140.
而後，在塞槽110之卡***方向(箭頭A方向)的裡端設有用於檢測卡之***的檢測開關130。該檢測開關130由彼此接觸分離之第一觸頭131及第 二觸頭132構成。 Then, a detection switch 130 for detecting insertion of the card is provided at the inner end of the card insertion direction (arrow A direction) of the slot 110. The detecting switch 130 is separated from the first contact 131 and the first The two contacts 132 are formed.
如第十二圖(B)所示，第一觸頭131係一端固定於塞槽110， 另一端延伸於與卡***方向正交之塞槽110寬度方向(第十二圖(B)之左右方向)的板簧構件。第一觸頭131將固定於塞槽110之一端作為固定端，另一端可在箭頭C及D所示的上下方向變位。而後，在第一觸頭131之另一端附近設有滑動接觸於卡140的滑動接觸部133。此外，在第一觸頭131之另一端設有延伸於上下方向之接點部134。 As shown in FIG. 12(B), the first contact 131 is fixed at one end to the plug groove 110, The other end extends through a leaf spring member in the width direction of the plug groove 110 (the left-right direction of the twelfth diagram (B)) orthogonal to the card insertion direction. The first contact 131 is fixed to one end of the plug groove 110 as a fixed end, and the other end can be displaced in the up and down direction indicated by arrows C and D. Then, a sliding contact portion 133 that is in sliding contact with the card 140 is provided near the other end of the first contact 131. Further, a contact portion 134 extending in the vertical direction is provided at the other end of the first contact 131.
此外，第二觸頭132係一端固定於塞槽110，另一端朝向第一 觸頭131側而延伸於塞槽110之寬度方向的板簧構件。在第二觸頭132之另一端附近設有卡140抵接之抵接部136。在第二觸頭132之另一端設有與第一觸頭131之接點部134的後面接觸之接點部135。接點部135彈性接觸於第一觸頭131之接點部134的後面。 In addition, the second contact 132 has one end fixed to the slot 110 and the other end facing the first The leaf spring member extends in the width direction of the plug groove 110 on the side of the contact 131. An abutting portion 136 that the card 140 abuts is provided near the other end of the second contact 132. A contact portion 135 that is in contact with the rear surface of the contact portion 134 of the first contact 131 is provided at the other end of the second contact 132. The contact portion 135 is elastically contacted to the rear of the contact portion 134 of the first contact 131.
而後，在卡140之***作業時，在第十三圖(A)所示之卡 140抵接於第一觸頭131的滑動接觸部133之前的狀態下，第二觸頭132之接點部135接觸於第一觸頭131之接點部134，開關形成關閉狀態。 Then, when the card 140 is inserted into the work, the card shown in the thirteenth figure (A) In a state before the sliding contact portion 133 of the first contact 131 abuts, the contact portion 135 of the second contact 132 contacts the contact portion 134 of the first contact 131, and the switch forms a closed state.
從該狀態使卡140向箭頭A方向進行。因而如第十三圖(B)所示，卡140之前端接觸於第一觸頭131之滑動接觸部133的彎曲引導面。 From this state, the card 140 is caused to proceed in the direction of the arrow A. Thus, as shown in the thirteenth diagram (B), the front end of the card 140 is in contact with the curved guiding surface of the sliding contact portion 133 of the first contact 131.
而後，卡140之***進行時，如第十三圖(C)所示，卡140 使滑動接觸部133下降而搭乘其上。此時，第一觸頭131之接點部134亦下降，該接點部134對第二觸頭132之接點部135滑動。亦即，執行所謂摩擦接觸動作，而拂去附著於接點部134、135之雜質。 Then, when the insertion of the card 140 is performed, as shown in the thirteenth (C), the card 140 The sliding contact portion 133 is lowered and rides thereon. At this time, the contact portion 134 of the first contact 131 also descends, and the contact portion 134 slides on the contact portion 135 of the second contact 132. That is, the so-called frictional contact action is performed, and the impurities adhering to the contact portions 134, 135 are removed.
進一步，卡140之***進行時，如第十三圖(D)所示，卡140之前端使 第二觸頭132之接點部135按壓移動於卡***方向，接點部135從第一觸頭131之接點部134離開。藉此，開關成為打開狀態，而探測卡140之***。 Further, when the insertion of the card 140 is performed, as shown in the thirteenth diagram (D), the front end of the card 140 is made The contact portion 135 of the second contact 132 is pressed and moved in the card insertion direction, and the contact portion 135 is separated from the contact portion 134 of the first contact 131. Thereby, the switch is turned on, and the insertion of the probe card 140 is performed.
此外，卡之抽出作業時的動作，與上述***作業時之動作相反，在該卡之抽出作業時亦執行摩擦接觸動作。 Further, the operation at the time of the card drawing operation is reversed from the operation at the time of the above-described insertion work, and the friction contact operation is also performed at the time of the card drawing operation.
根據該卡連接器101，係藉由第一觸頭131之接點部134在上下方向移動來執行摩擦接觸動作。因而，即使檢測開關130之動作行程短，仍可在第一及第二觸頭131、132之間獲得充分且確實的摩擦接觸動作。 According to the card connector 101, the frictional contact operation is performed by the contact portion 134 of the first contact 131 moving in the vertical direction. Therefore, even if the operation stroke of the detecting switch 130 is short, a sufficient and reliable frictional contact action can be obtained between the first and second contacts 131, 132.

但是，該過去之第十二圖及第十三圖所示的卡連接器101中存在以下之問題。 However, the following problems exist in the card connector 101 shown in the twelfth and thirteenth drawings.
亦即，卡連接器101之情況，如第十三圖(D)所示，即使在卡140之***完成狀態下，進行摩擦接觸動作之第一觸頭131的接點部134係配置成比卡140之前端仍保留於箭頭A所示之卡***方向的裡側。因而，欲縮短卡連接器101之卡***方向的長度有限度。 That is, in the case of the card connector 101, as shown in the thirteenth diagram (D), even when the insertion of the card 140 is completed, the contact portion 134 of the first contact 131 that performs the frictional contact operation is arranged to be larger than The front end of the card 140 remains in the inner side of the card insertion direction indicated by the arrow A. Therefore, it is desirable to shorten the length of the card insertion direction of the card connector 101 to a limited extent.
因此，本發明係鑑於該問題而研創者，其目的為提供一種卡連接器，其具有藉由構成檢測開關之觸頭的接點部在上下方向移動，可執行摩擦接觸動作，並且可縮短卡***方向之長度的用於檢測卡之***及抽 出的檢測開關。 Accordingly, the present invention has been made in view of the above problems, and an object thereof is to provide a card connector having a contact portion that constitutes a contact of a detecting switch in a vertical direction, which can perform a frictional contact action and can shorten a card The length of the insertion direction is used to detect the insertion and pumping of the card. The detection switch is out.
為了達成上述目的，本發明一種樣態之卡連接器，係具有安裝於容納卡之塞槽，用於檢測卡之***及抽出的檢測開關，其特徵為：前述檢測開關由彼此接觸分離之第一及第二觸頭構成，而前述第一觸頭具備：固定部，其係配置於前述卡之***路徑中途，並且固定於前述塞槽；凸輪部，其係從該固定部延伸而與前述卡嚙合；及第一接點部，其係從該凸輪部延伸，前述第二觸頭具備：固定部，其係固定於前述塞槽；彈性臂部，其係從該固定部延伸；及第二接點部，其係從該彈性臂部延伸，比前述第一接點部位於卡***方向之裡側，而對前述第一接點部彈性接觸，前述卡***時，前述卡之前端抵接於前述第一觸頭之前述凸輪部，前述卡之***進行時，前述卡使前述凸輪部下降並搭乘其上，前述第一接點部下降，對前述第二接點部進行摩擦接觸動作，前述卡之***進一步進行時，前述第一接點部之摩擦接觸動作結束，並且前述卡之前端通過前述第一接點部之上方而抵接於前述第二接點部，前述卡之***進一步進行時，前述卡之前端使前述第二接點部按壓移動於卡***方向之裡側，形成前述第二接點部可從前述第一接點部離開。 In order to achieve the above object, a card connector of the present invention has a detecting slot mounted on a receiving slot of a receiving card for detecting insertion and withdrawal of the card, wherein the detecting switch is separated from each other by a contact. And the first contact includes: a fixing portion disposed in the middle of the insertion path of the card and fixed to the plug groove; and a cam portion extending from the fixing portion and the foregoing a card engaging portion; and a first contact portion extending from the cam portion, wherein the second contact includes: a fixing portion fixed to the plug groove; and an elastic arm portion extending from the fixing portion; and a two-contact portion extending from the elastic arm portion and located inward of the first contact portion in the card insertion direction, and elastically contacting the first contact portion, the front end of the card being abutted when the card is inserted When the card is inserted into the cam portion of the first contact, the card lowers and rides the cam portion, the first contact portion descends, and the second contact portion is frictionally contacted , the aforementioned When the insertion is further performed, the frictional contact operation of the first contact portion is completed, and the front end of the card abuts against the second contact portion through the upper side of the first contact portion, and the insertion of the card is further performed. The front end of the card causes the second contact portion to be pressed and moved inward of the card insertion direction, and the second contact portion is formed to be detachable from the first contact portion.
此外，該卡連接器中，前述第一觸頭係從固定於前述塞槽之接地板(Ground Plate)延伸的接地觸頭(Ground Contact)，且前述第一觸頭在前述第二接點部從前述第一接點部離開狀態下，宜可接觸於形成在前述卡之背面的接地用焊墊。 In addition, in the card connector, the first contact is a ground contact extending from a ground plate of the plug groove, and the first contact is at the second contact portion. It is preferable to be in contact with the grounding pad formed on the back surface of the card from the state in which the first contact portion is separated.
根據本發明之卡連接器，在卡***時，卡抵接於第一觸頭之 凸輪部，卡之***進行時，卡使凸輪部下降並搭乘其上，第一觸頭之第一接點部下降，而對第二觸頭之第二接點部進行摩擦接觸動作。此外，卡抽出時，第一觸頭進行與卡***時相反之動作。因而，可藉由檢測開關之第一觸頭的第一接點部在上下方向移動來執行摩擦接觸動作，可在第一及第二觸頭之間獲得充分且確實之摩擦接觸動作。 According to the card connector of the present invention, when the card is inserted, the card abuts against the first contact In the cam portion, when the card is inserted, the card lowers the cam portion and rides thereon, the first contact portion of the first contact is lowered, and the second contact portion of the second contact is frictionally contacted. Further, when the card is withdrawn, the first contact performs the opposite action as when the card is inserted. Therefore, the frictional contact action can be performed by detecting that the first contact portion of the first contact of the switch moves in the up and down direction, and a sufficient and reliable frictional contact action can be obtained between the first and second contacts.
此外，卡之***進一步進行時，第一接點部之摩擦接觸動作 結束，並且卡之前端通過第一接點部上方而抵接於第二接點部，卡之***進一步進行時，卡之前端使第二接點部按壓移動於卡***方向的裡側，第二接點部即從前述第一接點部離開。因而，在卡之***完成狀態下，進行摩擦接觸動作之第一觸頭的第一接點部位於卡之下側。藉此，可縮短卡連接器在卡***方向之長度。 In addition, when the insertion of the card is further performed, the frictional contact action of the first contact portion When the card is inserted and the front end of the card abuts against the second contact portion through the first contact portion, the card insertion end moves the second contact portion to the inner side of the card insertion direction. The two contact portions are separated from the first contact portion. Therefore, in the state in which the insertion of the card is completed, the first contact portion of the first contact that performs the frictional contact action is located on the lower side of the card. Thereby, the length of the card connector in the card insertion direction can be shortened.

Each of the side surface portions 32 extends downward from each of the side surfaces in the width direction of the flat portion 31. Further, the rear portion 33 extends downward from the rear surface of the flat portion 31. The outer casing 30 is formed by punching and bending a metal plate.
再者，檢測開關40係用於檢測卡60之***及抽出者，且如第 一圖所示，配置於卡連接器1之後方側，亦即配置於卡***方向裡側。如第二圖所示，檢測開關40係由彼此接觸分離之第一觸頭41及第二觸頭42而構成。如第四圖及第五圖所示，檢測開關40係在卡60之前端抵接於第一觸頭41的凸輪部41b之前的狀態下，第一觸頭41接觸於第二觸頭42而開關為關閉的常閉型。該開關為關閉狀態時，檢測卡之抽出。而後，如第八圖至第十 一圖所示，卡60之前端使第二觸頭42按壓移動於卡***方向的裡側，第二觸頭從第一觸頭41離開，開關為打開。該開關為打開狀態時，檢測卡之***。 Furthermore, the detection switch 40 is used to detect the insertion and extraction of the card 60, and As shown in the figure, it is disposed on the rear side of the card connector 1, that is, in the card insertion direction. As shown in the second figure, the detecting switch 40 is constituted by the first contact 41 and the second contact 42 that are in contact with each other. As shown in the fourth and fifth figures, the detecting switch 40 is in a state in which the front end of the card 60 abuts against the cam portion 41b of the first contact 41, and the first contact 41 is in contact with the second contact 42. The switch is normally closed with the switch off. When the switch is in the off state, the detection card is pulled out. Then, as shown in the eighth to tenth As shown in the figure, the front end of the card 60 causes the second contact 42 to be pressed and moved to the inner side of the card insertion direction, the second contact is separated from the first contact 41, and the switch is opened. When the switch is in the open state, the insertion of the test card is performed.
在此，構成檢測開關40之第一觸頭41，如第五圖、第六圖、 第七圖、第九圖及第十一圖所示，係配置於卡60***卡***空間17後達到卡嵌合狀態為止的卡60之***路徑的中途。具體而言，第一觸頭41係配置於卡60之***路徑中，比接地觸頭21後方側，亦即係配置於卡***方向之裡側。該第一觸頭41係藉由將導電性金屬板沖裁及彎曲加工而形成，且如第五圖所示，具備固定於塞槽10之底壁11的固定部41a。固定部41a係從***成形於塞槽10之底壁11的導電性之接地板27延伸。因而，第一觸頭41構成接地觸頭。第一觸頭41係形成將固定部41a作為固定端之懸臂梁狀，其前端可在第五圖所示之箭頭Z1表示的上方向及箭頭Z2表示的下方向變位。而後，第一觸頭具備從固定部41a延伸於後方向，亦即箭頭X表示之卡***方向且斜上方向的凸輪部41b。如第五圖所示，該凸輪部41b突出於卡***空間17內。而後，如第六圖及第七圖所示，在該凸輪部41b中嚙合卡60之前端，形成在第一觸頭41前端之後述的第一接點部41c上下移動。再者，第一觸頭41具備從凸輪部41b之前端向下方延伸之接觸部41d，在其接觸部41d之前端設有第一接點部41c。接觸部41d接觸於卡60之背面，在後述之第二觸頭42的第二接點部42d從第一接點部41c離開的狀態下，可接觸於卡60之背面所形成的接地用焊墊61。第一接點部41c係以沖裁導電性金屬板時所形成的剪切角邊緣而形成。 Here, the first contact 41 of the detecting switch 40 is formed, as shown in FIG. 5 and FIG. The seventh, ninth, and eleventh drawings are disposed in the middle of the insertion path of the card 60 until the card 60 is inserted into the card insertion space 17 and the card is fitted. Specifically, the first contact 41 is disposed in the insertion path of the card 60, and is disposed on the rear side of the ground contact 21, that is, on the back side of the card insertion direction. The first contact 41 is formed by punching and bending a conductive metal plate, and as shown in FIG. 5, has a fixing portion 41a fixed to the bottom wall 11 of the plug groove 10. The fixing portion 41a extends from the conductive ground plate 27 inserted into the bottom wall 11 of the plug groove 10. Thus, the first contact 41 constitutes a ground contact. The first contact 41 has a cantilever shape in which the fixed portion 41a is a fixed end, and its front end is displaceable in the upward direction indicated by an arrow Z1 shown in FIG. 5 and in the downward direction indicated by an arrow Z2. Then, the first contact is provided with a cam portion 41b extending from the fixing portion 41a in the rear direction, that is, the card insertion direction indicated by the arrow X and obliquely upward. As shown in the fifth figure, the cam portion 41b protrudes into the card insertion space 17. Then, as shown in the sixth and seventh figures, the first contact portion 41c, which will be described later at the front end of the first contact 41, is moved up and down in the front end of the cam portion 41b that engages the card 60. Further, the first contact 41 has a contact portion 41d extending downward from the front end of the cam portion 41b, and a first contact portion 41c is provided at a front end of the contact portion 41d. The contact portion 41d is in contact with the back surface of the card 60, and the ground contact welding formed on the back surface of the card 60 can be contacted in a state where the second contact portion 42d of the second contact 42 to be described later is separated from the first contact portion 41c. Pad 61. The first contact portion 41c is formed by cutting the edge of the sheared corner formed when the conductive metal plate is punched.
此外，如第二圖所示，第二觸頭42係藉由將導電性金屬板沖 裁及彎曲加工而形成，且具備固定於塞槽10之後端左壁16的固定部42a。第二觸頭42形成將固定部42a作為固定端之懸臂梁狀，形成其前端可在後方向(箭頭X表示之卡***方向)及前方向(箭頭Y表示之卡排出方向)變位。而後，第二觸頭42具備：從固定部42a延伸於寬度方向右側且稍微斜前方向的第一彈性臂部42b；及從第一彈性臂部42b之前端延伸於寬度方向右側且更斜前方向的第二彈性臂部42c。而藉由第一彈性臂部42b及第二彈性臂部42c構成申請專利範圍第1項中規定之彈性臂部。再者，第二觸頭42具備從第二彈性臂部42c之前端與塞槽10之寬度方向大致平行地延伸於寬度方向右側的第二接點部42d。如第五圖所示，第二接點部42d比第一觸頭41之第一接點部41c位於卡***方向的裡側。而後，在卡60之前端抵接於第二接點部42d之前的狀態，係第二接點部42d彈性接觸於第一接點部41c。第二接點部42d以上下方向延伸之平板而形成，且第一接點部41c之剪切角邊緣對其滾筒面接觸。 In addition, as shown in the second figure, the second contact 42 is formed by punching a conductive metal plate It is formed by cutting and bending, and has a fixing portion 42a fixed to the rear left wall 16 of the plug groove 10. The second contact 42 has a cantilever shape in which the fixing portion 42a is a fixed end, and the front end thereof is deformed in the rear direction (the card insertion direction indicated by the arrow X) and the front direction (the card discharge direction indicated by the arrow Y). Then, the second contact 42 includes a first elastic arm portion 42b extending from the fixed portion 42a in the width direction right side and slightly obliquely forward; and extending from the front end of the first elastic arm portion 42b to the right side in the width direction and more obliquely The second elastic arm portion 42c in the direction. The first elastic arm portion 42b and the second elastic arm portion 42c constitute the elastic arm portion defined in the first item of the patent application. Further, the second contact 42 includes a second contact portion 42d that extends from the front end of the second elastic arm portion 42c substantially parallel to the width direction of the plug groove 10 in the width direction right side. As shown in the fifth figure, the second contact portion 42d is located on the back side of the card insertion direction than the first contact portion 41c of the first contact 41. Then, in a state before the front end of the card 60 abuts against the second contact portion 42d, the second contact portion 42d elastically contacts the first contact portion 41c. The second contact portion 42d is formed by a flat plate extending in the lower direction, and the sheared edge edge of the first contact portion 41c is in surface contact with the drum surface.
再者，彈出機構50係可藉由所謂推一推作用而排出卡60者，且具有習知之構成。簡言之，彈出機構50具備可與卡60一起在卡***方向及卡排出方向移動之滑塊51。在滑塊51之表面形成心形之凸輪溝52，軸支撐於塞槽10之前端右壁12的凸輪銷53前端位於該凸輪溝52內。而後，在滑塊51與塞槽10的後端右壁15之間配設將滑塊51施力於卡排出方向的彈簧構件54。 Further, the eject mechanism 50 can be configured to discharge the card 60 by a so-called push-push action, and has a conventional configuration. In short, the eject mechanism 50 is provided with a slider 51 that is movable in the card insertion direction and the card ejecting direction together with the card 60. A heart-shaped cam groove 52 is formed on the surface of the slider 51, and the front end of the cam pin 53 whose shaft is supported at the front right wall 12 of the plug groove 10 is located in the cam groove 52. Then, a spring member 54 that biases the slider 51 in the card discharge direction is disposed between the slider 51 and the rear end right wall 15 of the plug groove 10.
其次，參照第四圖至第十一圖說明檢測開關40之作用。 Next, the action of the detecting switch 40 will be described with reference to the fourth to eleventh drawings.
首先，考慮卡60尚未***卡連接器1之卡***空間17，或是如第四圖及第五圖所示，在該卡***空間17中***卡60，卡60之前端抵接於第一觸頭 41的凸輪部41b之前的狀態。此時，第二觸頭42之第二接點部42d彈性接觸於第一觸頭41之第一接點部41c，開關為關閉。藉此，檢測為卡未***。 First, it is considered that the card 60 has not been inserted into the card insertion space 17 of the card connector 1, or as shown in the fourth and fifth figures, the card 60 is inserted into the card insertion space 17, and the front end of the card 60 abuts the first Contact The state before the cam portion 41b of 41. At this time, the second contact portion 42d of the second contact 42 elastically contacts the first contact portion 41c of the first contact 41, and the switch is closed. Thereby, it is detected that the card is not inserted.
而後，此時接地用觸頭21尚未接觸於設在卡60背面之接地用焊墊61，此外，信號用觸頭22~26尚未接觸於信號用焊墊62~66。 Then, at this time, the grounding contact 21 is not in contact with the grounding pad 61 provided on the back surface of the card 60, and the signal contacts 22 to 26 are not yet in contact with the signal pads 62 to 66.
其次，從第四圖及第五圖所示之狀態，使卡60在箭頭X表示之卡***方向進行。因而如第六圖所示，卡60之前端抵接於第一觸頭41之凸輪部41b。而後，卡60之***進行時，如第七圖所示，卡60使凸輪部41b下降且搭乘其上。此時，第一觸頭41之第一接點部41c下降，而對第二觸頭42之第二接點部42d進行摩擦接觸動作。而後，卡60之***進一步進行時，第一接點部41c之摩擦接觸動作結束，並且卡60之前端通過第一接點部41c的上方而抵接於第二接點部42d。 Next, from the state shown in the fourth and fifth figures, the card 60 is caused to proceed in the card insertion direction indicated by the arrow X. Therefore, as shown in the sixth figure, the front end of the card 60 abuts against the cam portion 41b of the first contact 41. Then, when the insertion of the card 60 is performed, as shown in the seventh figure, the card 60 lowers the cam portion 41b and rides thereon. At this time, the first contact portion 41c of the first contact 41 is lowered, and the second contact portion 42d of the second contact 42 is subjected to a frictional contact operation. Then, when the insertion of the card 60 is further performed, the frictional contact operation of the first contact portion 41c is completed, and the front end of the card 60 abuts against the second contact portion 42d through the upper side of the first contact portion 41c.
而後，從第七圖所示之狀態使卡60的***進一步進行，卡60之前端壓入直至抵接於設於塞槽10的後端左壁16。因而，成為第八圖及第九圖所示之卡排除狀態。該卡排除狀態，係卡60之前端使第二觸頭42之第二接點部42d按壓移動於卡***方向的裡側，第二接點部42d從第一觸頭41之第一接點部41c離開。藉此，開關為打開，而檢測卡60之***。 Then, the insertion of the card 60 is further performed from the state shown in the seventh figure, and the front end of the card 60 is pressed in until it abuts against the rear end left wall 16 provided in the plug groove 10. Therefore, the card elimination state shown in the eighth diagram and the ninth diagram is obtained. In the card removal state, the front end of the card 60 causes the second contact portion 42d of the second contact 42 to be pressed and moved to the back side of the card insertion direction, and the second contact portion 42d is connected from the first contact of the first contact 41. The portion 41c leaves. Thereby, the switch is opened and the insertion of the card 60 is detected.
該卡排除狀態，係接地用觸頭21接觸於設於卡60背面的接地用焊墊61，此外，信號用觸頭22~26接觸於信號用焊墊62~66。 In the card removal state, the grounding contact 21 is in contact with the grounding pad 61 provided on the back surface of the card 60, and the signal contacts 22 to 26 are in contact with the signal pads 62 to 66.
此外，此時如第九圖所示，構成接地觸頭之第一觸頭41的接觸部41d接觸於形成在卡60背面的接地用焊墊61。因而，第一觸頭41也一併具備作為開關觸頭之功能與作為接地觸頭之功能，而無須另外設置接地觸頭，可謀求減少零件數量及降低成本。此外，已預定即使第一觸頭41接觸 於卡60之接地用焊墊61，仍使第一觸頭41作為接地觸頭之功能。因而，不致因第一觸頭41接觸於接地用焊墊61而造成短路。 Further, at this time, as shown in FIG. 9, the contact portion 41d of the first contact 41 constituting the ground contact is in contact with the ground pad 61 formed on the back surface of the card 60. Therefore, the first contact 41 also has a function as a switch contact and a function as a ground contact, and it is not necessary to separately provide a ground contact, thereby reducing the number of parts and reducing the cost. In addition, it has been predetermined that even the first contact 41 is in contact The grounding pad 61 of the card 60 still functions as the grounding contact of the first contact 41. Therefore, the short circuit is not caused by the first contact 41 coming into contact with the ground pad 61.
而後，在第九圖所示之卡排除狀態下，手從卡60離開而釋放時，藉由彈出機構50之作用，如第十圖及第十一圖所示，卡60在箭頭Y表示之卡排出方向移動，而成為卡嵌合狀態。 Then, in the card removal state shown in the ninth figure, when the hand is released from the card 60 and released, by the action of the eject mechanism 50, as shown in the tenth and eleventh figures, the card 60 is indicated by the arrow Y. The card discharge direction moves to become a card fitting state.
該卡嵌合狀態下，雖然第二觸頭42之第二接點部42d仍維持在抵接於卡60的前端，不過已與第一觸頭41之第一接點部41c分離。因而，維持開關打開狀態，且維持檢測出卡之***的狀態。 In the card fitting state, the second contact portion 42d of the second contact 42 is maintained in contact with the front end of the card 60, but is separated from the first contact portion 41c of the first contact 41. Thus, the switch is kept open, and the state in which the card is inserted is maintained.
此外，該卡嵌合狀態係維持接地用觸頭21接觸於設在卡60背面之接地用焊墊61的狀態，此外，係維持信號用觸頭22~26接觸於信號用焊墊62~66之狀態。 Further, the card fitting state maintains the state in which the ground contact 21 is in contact with the grounding pad 61 provided on the back surface of the card 60, and the sustaining signal contacts 22 to 26 are in contact with the signal pads 62 to 66. State.
另外，關於構成接地觸頭之第一觸頭41的接觸部41d，在卡60之嵌合狀態，如第十一圖(A)所示，有時形成於卡60背面之接地用焊墊61的長度縮短，而不接觸於該接地用焊墊61。此外，如第十一圖(B)所示，亦有時形成於卡60背面之接地用焊墊61的長度較長，而第一觸頭41之接觸部41d接觸於該接地用焊墊61。 Further, the contact portion 41d of the first contact 41 constituting the ground contact is formed in the fitting state of the card 60, as shown in FIG. 11(A), and may be formed on the grounding pad 61 on the back surface of the card 60. The length is shortened without contacting the grounding pad 61. Further, as shown in FIG. 11(B), the length of the grounding pad 61 formed on the back surface of the card 60 may be long, and the contact portion 41d of the first contact 41 may be in contact with the grounding pad 61. .
另外，從卡***空間17抽出卡60時，係將卡60從卡嵌合狀態先按壓於卡***方向。而後，當手從卡60離開時，藉由彈出機構50之彈簧構件54的作用將卡60施力於卡排出方向，藉此可從卡***空間17抽出卡60。在該卡60之抽走過程中，第一觸頭41及第二觸頭42係進行與卡60之***過程相反的動作。 Further, when the card 60 is taken out from the card insertion space 17, the card 60 is first pressed in the card insertion direction from the card fitting state. Then, when the hand is separated from the card 60, the card 60 is biased in the card discharge direction by the action of the spring member 54 of the eject mechanism 50, whereby the card 60 can be withdrawn from the card insertion space 17. During the pumping of the card 60, the first contact 41 and the second contact 42 perform the opposite action to the insertion of the card 60.
換言之，從第十圖及第十一圖所示之卡嵌合狀態，先將卡60 按壓於卡***方向時，成為第八圖及第九圖所示之卡排除狀態。此時，卡60之前端使第二觸頭42之第二接點部42d按壓移動於卡***方向的裡側，仍然維持第二接點部42d從第一觸頭41之第一接點部41c離開。因此，係維持開關之打開狀態，且維持檢測出卡之***的狀態。 In other words, from the card fitting state shown in the tenth and eleventh figures, the card 60 is first used. When pressed in the card insertion direction, the card is in the excluded state shown in the eighth and ninth drawings. At this time, the front end of the card 60 causes the second contact portion 42d of the second contact 42 to be pressed and moved to the inner side in the card insertion direction, and the second contact portion 42d is still maintained from the first contact portion of the first contact 41. 41c left. Therefore, the open state of the switch is maintained, and the state in which the card is inserted is maintained.
而後，在該卡排除狀態下，當手從卡60離開時，藉由彈出機構50之彈簧構件54的作用，將卡60施力於卡排出方向，經過第七圖及第六圖所示之狀態後，成為第五圖所示之卡排出狀態。 Then, in the card removal state, when the hand is separated from the card 60, the card 60 is biased in the card discharge direction by the action of the spring member 54 of the eject mechanism 50, as shown in the seventh and sixth figures. After the status, it becomes the card discharge state shown in the fifth figure.
在此，從卡排除狀態變成第七圖所示之狀態時，第二觸頭42之第二接點部42d抵接於第一觸頭41之第一接點部41c。藉此，開關成為關閉狀態，且成為檢測出卡未***之狀態。而後，從第七圖所示之狀態變成第六圖所示之狀態時，卡60之前端從第二觸頭42之第二接點部42d離開，第一觸頭41之凸輪部41b上昇。藉此，第一接點部41c上昇而對第二接點部42d進行摩擦接觸動作。在第四圖及第五圖所示之卡排出狀態，係維持第二接點部42d對第一接點部41c之接觸狀態，且維持開關之關閉狀態。 Here, when the card removal state is changed to the state shown in FIG. 7, the second contact portion 42d of the second contact 42 abuts against the first contact portion 41c of the first contact 41. Thereby, the switch is turned off, and it is detected that the card is not inserted. Then, when the state shown in Fig. 7 is changed to the state shown in Fig. 6, the front end of the card 60 is separated from the second contact portion 42d of the second contact 42, and the cam portion 41b of the first contact 41 is raised. Thereby, the first contact portion 41c is raised to perform the frictional contact operation on the second contact portion 42d. In the card discharge state shown in the fourth and fifth figures, the contact state of the second contact portion 42d with respect to the first contact portion 41c is maintained, and the closed state of the switch is maintained.
如此，根據本實施形態之卡連接器1，在卡60***時，卡60抵接於第一觸頭41之凸輪部41b。而後，卡60之***進行時，卡60使凸輪部41b下降且搭乘其上，第一觸頭41之第一接點部41c下降，而對第二觸頭42之第二接點部42d進行摩擦接觸動作。此外，卡60抽走時，第一觸頭41進行與卡60***時相反之動作。因而，藉由檢測開關40之第一觸頭41的第一接點部41c於上下方向移動，可執行摩擦接觸動作，可在第一及第二觸頭41,42之間獲得充分且確實之摩擦接觸動作。 As described above, according to the card connector 1 of the present embodiment, when the card 60 is inserted, the card 60 abuts against the cam portion 41b of the first contact 41. Then, when the insertion of the card 60 is performed, the card 60 lowers the cam portion 41b and rides thereon, the first contact portion 41c of the first contact 41 is lowered, and the second contact portion 42d of the second contact 42 is lowered. Frictional contact action. Further, when the card 60 is withdrawn, the first contact 41 performs the opposite action as when the card 60 is inserted. Therefore, by detecting the first contact portion 41c of the first contact 41 of the switch 40 moving in the up and down direction, a frictional contact operation can be performed, and sufficient and reliable can be obtained between the first and second contacts 41, 42. Frictional contact action.
此外，第一接點部41c下降，對第二接點部42d進行摩擦動作 後，卡60之***進一步進行時，第一接點部41c之摩擦接觸動作結束。同時，卡60之前端通過第一接點部41c之上方而抵接於第二接點部42d。而後，卡60之***進一步進行時，卡60之前端使第二接點部42d按壓移動於卡***方向的裡側，第二接點部42d即從第一接點部41c離開。因而，在卡60之***完成的狀態，亦即卡嵌合狀態，進行摩擦接觸動作之第一觸頭41的第一接點部41c位於卡之下側。因而，可縮短卡連接器1之卡***方向的長度。 Further, the first contact portion 41c is lowered, and the second contact portion 42d is rubbed. Thereafter, when the insertion of the card 60 is further performed, the frictional contact operation of the first contact portion 41c is completed. At the same time, the front end of the card 60 abuts against the second contact portion 42d through the upper side of the first contact portion 41c. Then, when the insertion of the card 60 is further performed, the second contact portion 42d is pressed and moved to the back side in the card insertion direction at the front end of the card 60, and the second contact portion 42d is separated from the first contact portion 41c. Therefore, in the state in which the insertion of the card 60 is completed, that is, in the card fitting state, the first contact portion 41c of the first contact 41 that performs the frictional contact operation is located on the lower side of the card. Thus, the length of the card connector 1 in the card insertion direction can be shortened.
另外，第二觸頭42之第二接點部42d係以上下方向延伸之平板而形成，且第一觸頭41之第一接點部41c的剪切角邊緣可對其滾筒面接觸。因而，與各平面彼此接觸時比較，可提高第一接點部41c對第二接點部42d接觸時的赫茲應力(Hertz Stress)。此外，亦可降低摩擦接觸動作時之接觸壓。 Further, the second contact portion 42d of the second contact 42 is formed by a flat plate extending in the lower direction, and the sheared edge edge of the first contact portion 41c of the first contact 41 is in surface contact with the roller. Therefore, the Hertz Stress when the first contact portion 41c comes into contact with the second contact portion 42d can be improved as compared with when the respective planes are in contact with each other. In addition, the contact pressure during the frictional contact action can also be reduced.
以上，係說明本發明之實施形態，不過本發明不限定於此，可進行各種變更、改良。 The embodiments of the present invention have been described above, but the present invention is not limited thereto, and various modifications and improvements can be made.
例如第一觸頭41之第一接點部41c的剪切角邊緣未必需要對第二接點部42d之滾筒面接觸。 For example, the shear angle edge of the first contact portion 41c of the first contact 41 does not necessarily need to be in contact with the roller surface of the second contact portion 42d.
此外，第一觸頭41除了作為開關觸頭的功能之外，未必需要一併具備作為接地觸頭之功能。 Further, the first contact 41 does not necessarily have to function as a ground contact in addition to the function as a switch contact.
