和將該彈性片部的前端側予以彎折而形成的基板卡合爪42 :及由「構成有該基板卡合爪42之彈簧片」的前端部所構 成的下側移動限制片43。 基板卡合爪42是由以下所構成：傾斜片部42a，該傾 斜片部42 a是將彈性片部4 1的前端朝斜下側延長而成；及 向上卡止片部42b，該向上卡止片部42b是將該傾斜片部 42a前端向上彎折後延長而成。 -12- 201119157 此外，在外殼本體28，於下側移動限制片43的上方位 置形成有：可供該下側移動限制片43朝上下出入移動的開 闊的退避用窗孔44。 接著，至少使基板卡合爪42的前端部，通過「開口形 成於殼體1〇上面」的細縫45而插入基板插入部20內。雖然 該實施例中的細縫45，其前方側，也就是指殼體1 〇前面側 ，是形成朝殼體前面開放的形狀，但也可以是朝殼體1 〇上 φ 面開放的窗孔狀。 在其中一個基板的連接器內插入片部a的左右兩緣部 ，形成有貫通上下的卡合爪嵌合部46，在該連接器內插入 片部a已插入至連接器內之特定深度的狀態下於卡合爪嵌 合部46的位置處，配置有前述基板卡合爪42。 下側移動限制片43，是藉由將前述向上卡止部42b的 前端，朝向殻體背面側彎折成水平所構成。 下側移動限制片43，是藉由使其下面抵接於「殼體1 0 • 上面的限制片抵接部47」，而形成限制朝下側的移動。 在外殼12處，於向上卡止片部42b的背面側，也就是 指殻體前面側，一體地形成有向下突出的前側移動限制片 50。該前側移動限制片50，是將「在外殼1 2上施以〔字型 切除而形成矩形」的舌片，向下彎折後形成的部分，在該 例子中，是利用衝裁前述退避用窗孔44時所衝斷後折彎的 舌片》 再者，雖然該前側移動限制片50並非必要的構件，但 可藉由與下側移動限制片43 —起使用，來增強基板A的耐 -13- 201119157 移除力。 接下來，說明上述FPC連接器的作用。 在基板A插入前，外殻12是重疊於殼體10的上面，而 接頭11的彈性接觸片部23是形成突出於基板插入部20內的 狀態。此時外殻1 2是形成：卡止突起卡合於夾具33，使豎 起方向的動作受到阻止的狀態。 在上述的狀態下，將基板A的連接器內插入片部a朝殼 體的基板插入部2 0內插入。此時，接頭1 1的彈性接觸片部 23是被插入片部a所按壓，而朝退避方向移動，在插入片 部a插入至特定深度爲止的狀態下，藉由彈性接觸片部23 的彈性而將接點部25按壓接觸於插入片部a的連接端子26 。同樣地，接地接頭38也被按壓接觸於插入片部a的接地 端子。 在插入該插入片部a時，因爲該插入片部a的前端緣滑 動於基板卡合爪42之傾斜片部42a的下面側，而將該基板 卡合爪42朝上側推起。此時，由於下側移動限制片43上升 至外殼本體28的退避用窗孔44內，因此基板卡合爪42可不 受干擾地上升。 接著，一旦插入片部a被插入至特定位置爲止，基板 卡合爪部42便將落入插入片部a的卡合爪嵌合部46內而形 成嵌合。 如此一來，在插入片部a已插入基板插入部20內的狀 態下，一旦受到某種原因而對基板A作用移除力時，卡合 爪嵌合部46的前端側緣部46a將接觸於基板卡合爪42的向 201119157 上卡止片部42b，而阻止移除。 一旦作用上述的移除力，雖然基板卡合爪42便將彈性 片部41的基端部作爲支點來對抗移除力，倘若所作用的移 除力大於該抵抗力時，基板卡合爪42將形成：作用使彈性 片部41側浮起之方向的力量，並作用使向上卡止片部42 a 向下的力量，但在此時，與基板卡合爪42呈一體的下側移 動限制片43，是抵接於殼體上面側而阻止向下動作，並防 φ 止基板卡合爪42朝向下側的旋轉動作，藉此可對抗更大的 移除力。 此外，由於在向上卡止片部42a的背面存在著前側移 動限制片50，因此當作用前述的移除力，而使基板卡合爪 42朝基板拉出方向移動時，向上卡止片部42b的背面側將 抵接於該限制片50而對抗朝向基板拉出方向的力量，並配 合前述下側移動限制片43的作用，而成爲對抗強大移除力 的構造。 • 因此，即使在因更小型化的需求，而藉由衝裁而在「 厚度爲0.1 mm以下的極薄外殼」上一體地形成基板卡合爪 分的場合中，也能對抗強大的移除力，而達成在小型化中 安全性更高的製品。 此外，在拔出所插入的基板A時，是在藉由將夾具33 朝開啓方向彎折而解除對外殼12之兩側板部29的卡止的狀 態下，使外殻1 2朝豎起於殼體上面的方向轉動。藉此，使 基板卡合爪42從殼體10的基板插入部20脫離，並釋放基板 A之拉出方向的拘束，而形成可容易拔出的狀態。 -15- 201119157 【圖式簡單說明】 第1圖：是顯示本發明中基板連接用連接器的其中一 例的俯視圖。 第2圖：爲第1圖之基板連接用連接器的前視圖。 第3圖：爲第1圖之基板連接用連接器的側視圖。 第4圖：爲第1圖所示的基板連接用連接器中，基板防 止脫落機構部分的縱剖面圖。 第5圖：爲顯示第1圖之基板連接用連接器的接頭部分 的縱剖面圖。 第6圖：爲第1圖的基板連接用連接器中，從前方下側 觀看外殼的立體圖。 第7圖：是從前方上側觀看上述外殼的立體圖。 第8圖：是顯示用來卡合上述外殼之夾具部分的局部 放大後視圖。 第9圖：是顯示藉由第1圖的基板連接用連接器所連接 之基板的其中一例，其中（a)爲局部底面圖，（b)爲局 部俯視圖。 第10圖：是顯示傳統基板連接用連接器的其中一例， 其中（a)爲連接器整體的俯視圖，（b)爲基板防止脫落 機構部分的縱剖面圖。 【主要元件符號說明】 A :基板 -16- 201119157 a :連接器內插入片部 10 :殼體 1 1 __接頭 1 2 :外殼 20 :基板插入部 2 1 :接頭固定溝 2 2 :支承片部 2 3 :彈性接觸片部 24 :連接端子部 2 5 :接點部 26 :連接端子 2 6 a :接地端子 2 8 :外殼本體部 29 :側板部 3 0 :軸承孔 3 1 :卡止突起 32 :支軸 33 :夾具 3 4 :接地構件 3 5 :向下片部 3 6 :支承片部 37 :卡止窗 3 8 :接地接頭 40 :帶狀彈簧片部 -17- 201119157 41 :彈性片部 4 2 :基板卡合爪 42a :傾斜片部 42b:向上卡止片部 43 :下側移動限制片 44 :退避用窗孔 45 :細縫 46 :卡合爪嵌合部 50 :前側移動限制片[Technical Field] The present invention mainly relates to a substrate for connecting a substrate such as an FPC or an FFC to another substrate or a device for connecting a substrate, and is for adding a substrate to be inserted. The connector for connecting the substrate for improving the removal force of the removal force. [Prior Art] Traditionally, in the ZIF (Zero Insertion Force) type and the NONZIF (Non Zero Insertion Force) type of substrate connection connector, a type of "overlap and card" has been developed. a housing that is coupled to the upper surface of the housing and that is rotatably disposed in a erecting direction, the housing is subjected to a cutting process to integrally form a spring piece portion, and the substrate engaging claw is integrally formed at the spring piece portion When the substrate is inserted into the connector, the substrate engagement claw is pressed by the substrate, and the substrate engagement claw is moved toward the "retracted to the upper side of #", and the card in which the substrate engagement claw is fitted to the substrate is formed. In the state of the joint portion, the substrate is prevented from falling off by a certain removal resistance (for example, Patent Document 1). In the above-described conventional FPC prevention device, the conventional technique shown in Patent Document 1 is to form an elastic sheet 3 which is formed by punching a part of the outer casing 2 which is also a shielding member, and is formed along the front end. One of the side edges is bent downward, and the non-return type substrate engaging claws 4 having a "front end triangular shape" are integrally formed, and the outer casing 2 serving as a shielding member is overlapped by the tenth figure. The conductive gold-5-201119157 is formed on the surface of the molded case 1 of the molded article. Then, the substrate 5 to be connected is placed in the casing 1 so that the substrate engaging claws 4 are fitted in the hole-like or notched contact preventing portion 6 formed in the substrate 5. [Problem to be Solved by the Invention] The conventional connector for connecting a substrate is highly functional and miniaturized by a portable electronic device such as a mobile phone. Significant miniaturization is required. In addition, the anti-drop mechanism is formed by punching and bending the outer casing which is also a masking material. Although it is simple in structure and easy to be compact, it has the following problems: When the force in the pull-out direction acts on any of the inserted substrates, the substrate engaging claws are liable to be broken in the board pulling-out direction. In view of the above conventional problems, an object of the present invention is to provide a substrate engaging claw which is formed by processing a casing which is superposed on an operating element, and which has a large removing force against the substrate. </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> Forming: -6 - 201119157 housing 'the housing has an elongated flat substrate insertion portion into which the connector of the substrate is interposed; and a joint at a specific interval of the width of the substrate insertion portion, and most of the arrays a connection terminal portion supported by the casing, exposed outside the casing, and a contact spring piece for connecting the substrate protruding from the base; and a casing 'the casing is formed of a metal plate, and the gold Φ is disposed as an overlap card Cooperating with the upper surface of the casing, and being freely rotatable in a erect direction; and having a substrate engaging claw which is integrally formed with the outer casing In the state in which the outer body is overlapped, the substrate is inserted from the upper surface side of the casing, and the insertion portion of the connector in the connector of the substrate is inserted, so that the substrate is engaged with the claw The substrate connection φ in the detachment preventing engagement portion provided in the splicing portion is formed by bending the spring piece portion to integrally form the engagement claw, and the substrate engagement claw is configured as follows: the inclined slant portion The front side of the substrate inserted into the substrate insertion portion is pushed up; and the sheet portion is upwardly bent, and the portion is bent upward and extended for the engagement of the engaging claws. The edge portion of the portion abuts to restrict the extraction side movement restricting piece of the substrate; the lower side movement restricting piece is integrally formed at a front end of the upward locking portion toward the flat direction of the casing, and the upper side thereof limits the substrate card The downward movement of the claws. The plate-insertion-incorporated sheet material is held in the insertion direction of the sheet insertion portion, and is formed in the casing and the casing insertion portion from the casing, and the substrate insertion portion is inserted into the substrate insertion portion. The tip end edge slides on the substrate of the upward locking piece and the water having the lower back side is in contact with the casing 201119157. The invention described in claim 2 is characterized by the fact that the structure of the request item 1 is The spring piece portion, the substrate engagement claw, and the lower movement restricting piece are integrally formed by bending a band-shaped spring piece portion integrally formed with the outer casing when the outer casing is molded. The invention is characterized in that, in addition to the configuration of any one of the request items 1 or 2, at the outer casing, at a position corresponding to the lower side movement restricting piece, the lower side movement restricting piece is allowed to face up and down The invention according to claim 4 is characterized in that, in addition to the configuration of any one of the claims 1 or 2, the outer casing is integrally provided with the outer casing. The front side movement restricting piece for restricting the operation of the upward locking piece portion toward the board pulling-out direction side is sagged on the back side of the upper locking piece portion of the substrate engaging claw. The feature of the invention described in claim 5 In addition to the structure of the request item 4, the "retracting window hole" is formed by punching the punching hole formed by the front side movement restricting piece. [Effect of the Invention] In the present invention, the substrate engaging claw is provided. The substrate engaging claw is integrally formed on the spring piece portion, and the spring piece portion is integrally formed with the outer casing formed of "a metal plate which is freely rotatable in a direction rising from the housing", and the substrate engaging claw is The outer casing is inserted into the substrate insertion portion from the upper surface side of the casing in a state in which the casing is overlapped with the casing, and the substrate card is inserted in a state in which the insertion portion of the substrate is inserted into the substrate insertion portion. 8-201119157 The claw connector is engaged with the insertion preventing portion of the insertion preventing portion provided in the insertion portion of the connector, and the base connector is formed by bending the spring piece portion. The card engaging claw is composed of an inclined piece portion that is pushed up by the front end edge of the substrate inserted into the substrate insertion portion, and is pushed upward: The upward locking piece portion is formed by bending the front end of the inclined piece portion upward and extending it to abut against an edge portion of the engaging claw fitting portion of the substrate, thereby restricting the pulling out of the substrate; a lower side movement restricting piece that is integrally formed at a front end of the upper locking portion and that is in contact with the front end side of the casing to restrict the downward movement of the substrate engaging claw, and functions after the substrate is inserted When the force is removed, the downward force is applied to the upward locking piece, but the downward movement restricting piece abuts against the upper surface side of the casing to prevent the downward movement, thereby preventing the rotation toward the lower side, This can fight against greater removal forces. Further, in the invention, the spring piece portion, the substrate engaging claw, and the lower movement restricting piece are bent at a time when the outer casing is molded, and the strip-shaped spring piece integrally formed with the outer casing is bent. It is formed whereby the above-described respective portions can be easily formed at low cost. Further, in the present invention, the retracting window opening for the lower side movement restricting piece to enter and exit in the vertical direction is provided at the position corresponding to the lower side movement restricting piece at the outer casing, and the retracting window hole can be enlarged. The vertical movement length of the side movement restricting piece can be easily matched even with a substrate having a thick material thickness. In the present invention, the outer casing is integrally provided with a "sag on the back side of the upper locking piece portion of the substrate engaging claw, and is used to restrict the upward locking piece portion toward the substrate pulling direction side of 201119157. When the above-described removal force acts on the substrate and the substrate engagement claw moves in the substrate pulling direction, the back side of the upward locking piece abuts against the front side movement restricting piece against the front side movement restricting piece. The force in the direction in which the substrate is pulled out is combined with the action of the aforementioned lower side movement restricting piece to form a structure against a larger removal force. Further, in the present invention, the retracting window hole is formed by punching "forming the front side movement restricting piece", and the material utilization rate can be reduced (refer to reducing the waste generated by the cutting). ) is better and can reduce the processing steps.

The rear end side of the portion 22 protrudes to the same height as the bottom surface of the casing; the arcuate contact portion 25 integrally formed at the front end portion of the elastic contact piece portion 23 is inserted into the substrate from the lower side of the casing. Within the department 20. Then, 'the insertion portion a of the connector in the connector is inserted into the substrate insertion portion 20'. The contact portion 25 presses the inserted sheet portion a and moves downward toward the lower side, and is inserted into the insertion portion a. In the completed position, the contact portion 25 is formed to elastically contact the connection terminal 26 of the board substrate. The outer casing 12 is formed by applying a punching and bending process to the conductive metal plate and is configured to overlap the upper surface of the casing 10 and cover the flat casing body portion on the upper surface of the casing 10. 28; and a pair of side plate portions 29 and 29 which are integrally formed into "a rectangular shape in which both end portions of the casing main body portion 28 are bent"; and a bearing hole 30 and a locking projection 31 are formed in the side plate portion 29. A support shaft 3 2 integrally formed on the side surface of the casing is fitted into the bearing hole 30 to form an outer φ shell 1 2 which is centered on the support shaft 32 and rotates between the following positions: The position above the housing 10 is up to a position above the housing. Fixings 3 3 are provided on both sides of the casing 10 for preventing the casing 12 from coming off and being engaged with the casing 12 being superposed on the casing. The jig 33 is integrally formed at both ends of the grounding member 34 fixed to the upper surface of the casing, and has a lower piece portion 35 that bends the grounding member 34 downward at the tip end of the grounding member 34, and includes: The support piece portion 36 that bends the lower end of the lower piece portion 35 toward the outer horizontal direction bends the front end of the support piece portion 36 upward by -11 - 201119157 to form the jig 3 3 . The side plate portions 29 at both ends of the outer casing are inserted between the lower piece portion 35 and the jig 3' and the side plate portion 29 is prevented from being detached from the support shaft 32 by the jig 33'. Further, a locking window 37 is formed by squeezing the jig 33, and a locking protrusion 31 for "punching and integrally forming the side plate portions 29, 29 of the outer casing 12" is engaged with the locking window 37. In a state in which the outer casing 12 is superposed on the upper surface of the casing, the locking projections 3 1 are fitted to the locking windows 37, whereby the outer casing 12 is not easily rotated in the vertical direction. Further, the tongue piece which is punched out by the formation of the locking window 37 is soldered to the ground terminal 39 which is "the board on which the connector is mounted (not shown in the drawing)". A grounding joint 38 is integrally formed in the grounding member 34, and its front end is inserted into the substrate insertion portion 20 of the casing 10 to form a grounding terminal 26a that is in contact with the substrate A. At the outer casing 12, a substrate prevention preventing mechanism is integrally provided at both end portions thereof. In the front side of the casing of the casing main body portion 28, that is, the strip spring portion 40 which is extended from the edge portion on the opening side of the substrate insertion portion toward the front side, the anti-drop mechanism has a U-shaped portion 40 which is folded downward toward the lower side. The elastic piece portion 4 1 of the shape and the substrate engagement claw 42 formed by bending the distal end side of the elastic piece portion and the front end portion of the "spring piece constituting the substrate engagement claw 42" The lower side moves the restriction piece 43. The substrate engaging claw 42 is configured by an inclined piece portion 42a that extends the front end of the elastic piece portion 41 from the obliquely lower side, and an upward locking piece portion 42b that is upwardly clicked. The stopper portion 42b is formed by bending the distal end of the inclined piece portion 42a upward. Further, in the casing main body 28, an upper retracting window opening 44 for allowing the lower side movement restricting piece 43 to move up and down is formed in the upper direction of the lower side movement restricting piece 43. Next, at least the distal end portion of the substrate engagement claw 42 is inserted into the substrate insertion portion 20 through the slit 45 which is "opened in the upper surface of the casing 1". Although the slit 45 in this embodiment has a shape in which the front side, that is, the front side of the casing 1 is formed to open toward the front of the casing, it may be a window opening which faces the φ face of the casing 1 shape. The right and left edge portions of the sheet portion a are inserted into the connector of one of the substrates, and the engagement claw fitting portion 46 that penetrates the upper and lower sides is formed, and the insertion portion a is inserted into the connector at a specific depth in the connector. In the state of the engagement claw fitting portion 46, the substrate engagement claws 42 are disposed. The lower side movement restricting piece 43 is formed by bending the front end of the upward locking portion 42b toward the back side of the casing to be horizontal. The lower side movement restricting piece 43 is formed so as to restrict the downward movement of the lower side by abutting against the "receiving piece abutting portion 47 of the upper surface of the casing 10". At the outer casing 12, on the back side of the upward locking piece portion 42b, that is, the front side of the casing, a front side movement restricting piece 50 projecting downward is integrally formed. The front side movement restricting piece 50 is a portion which is formed by bending a tongue which is formed into a rectangular shape by a shape cut in the outer casing 12, and in this example, the backing is used for punching. The tongue which is bent after the window hole 44 is broken. Further, although the front side movement restricting piece 50 is not an essential member, it can be used together with the lower side movement restricting piece 43 to enhance the resistance of the substrate A - 13- 201119157 Remove force. Next, the action of the above FPC connector will be explained. Before the insertion of the substrate A, the outer casing 12 is superposed on the upper surface of the casing 10, and the elastic contact piece portion 23 of the joint 11 is formed to protrude into the substrate insertion portion 20. At this time, the outer casing 12 is formed such that the locking projection is engaged with the jig 33 to prevent the movement in the vertical direction from being blocked. In the above state, the connector insertion portion a of the substrate A is inserted into the substrate insertion portion 20 of the casing. At this time, the elastic contact piece portion 23 of the joint 1 is pressed by the insertion piece portion a, and is moved in the retracting direction, and the elasticity of the elastic contact piece portion 23 is made in a state where the insertion piece portion a is inserted to a certain depth. The contact portion 25 is pressed into contact with the connection terminal 26 of the insertion piece portion a. Similarly, the grounding joint 38 is also pressed into contact with the ground terminal of the insertion piece a. When the insertion piece portion a is inserted, the front end edge of the insertion piece portion a slides on the lower surface side of the inclined piece portion 42a of the substrate engagement claw 42, and the substrate engagement claw 42 is pushed upward. At this time, since the lower side movement restricting piece 43 is raised into the retracting window hole 44 of the casing main body 28, the substrate engaging claw 42 can be raised without being disturbed. Then, when the insertion piece portion a is inserted into the specific position, the substrate engagement claw portion 42 is fitted into the engagement claw fitting portion 46 of the insertion piece portion a to be fitted. In this state, when the insertion piece portion a is inserted into the substrate insertion portion 20, when the removal force is applied to the substrate A for some reason, the front end side edge portion 46a of the engagement claw fitting portion 46 comes into contact. The sheet portion 42b is locked to the 201119157 of the substrate engaging claw 42 to prevent removal. Once the above-described removal force is applied, the substrate engaging claw 42 serves as a fulcrum for the base end portion of the elastic piece portion 41 as a fulcrum, and if the applied removal force is greater than the resistance, the substrate engaging claw 42 A force acting in a direction in which the elastic piece portion 41 is floated is formed, and acts to urge the downward direction of the piece 42 a downward, but at this time, the lower side movement restriction integral with the substrate engaging claw 42 is restricted. The sheet 43 abuts against the upper surface side of the casing to prevent downward movement, and prevents the rotation of the substrate engaging claw 42 toward the lower side, thereby resisting a larger removal force. Further, since the front side movement restricting piece 50 is present on the back surface of the upward locking piece portion 42a, when the above-described removal force acts to move the substrate engaging claw 42 toward the substrate pulling-out direction, the upper piece piece 42b is latched upward. The back side of the back side abuts against the restriction piece 50 against the force in the direction in which the substrate is pulled out, and cooperates with the action of the lower side movement restricting piece 43 to become a structure against strong removal force. • Therefore, even in the case where the substrate engagement claw is integrally formed on the "thin thin case having a thickness of 0.1 mm or less" by punching, it is possible to resist strong removal. Force to achieve higher safety products in miniaturization. Further, when the inserted substrate A is pulled out, the state of the outer side plate portion 29 of the outer casing 12 is released by bending the jig 33 in the opening direction, and the outer casing 12 is erected The direction above the housing rotates. Thereby, the substrate engagement claws 42 are detached from the substrate insertion portion 20 of the casing 10, and the restraining of the drawing direction of the substrate A is released, thereby forming a state in which it can be easily pulled out. -15-201119157 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a plan view showing an example of a connector for board connection in the present invention.
