[Prior Art] In recent years, electronic devices, such as mobile phones and digital cameras, are accelerating the miniaturization of products. In such an electronic device, an electronic component or a printed circuit board is installed. In order to connect such electronic parts and printed circuit boards, a flat and flexible FPC (Flexible Printed Circuit) and a connector for the FPC are mostly used. Therefore, this FPC connector is required to include a miniaturization with a reduced installation height (low profile). In order to solve this problem, there is a ZIF (Zero Insertion Force) type connector that can be inserted and removed with FPC almost effortlessly. This ZIF type connector can achieve low profile and prevent the cover from opening or flexing to ensure the conduction of the FPC. The ZIF type connector includes, for example, an insulating case having an opening, a plurality of connectors provided inside the case and extending toward the opening, and a cover member supported by the case and opening and closing the opening. (For example, refer to Japanese Patent Application Laid-Open No. 2002-252067.) The cover member has a support shaft mounted on the base end side and a fastening portion mounted on the front end side. The housing includes a guide support portion that supports the cover member support shaft to slide back and forth freely, and a lock portion that engages the cover member engagement portion. This connector closes the cover member in a state in which the support shaft of the cover member is located on the front side of the guide support portion. Then, the cover member is slid, the 89814.doc 1233238 support shaft of the cover member is moved to the rear side of the guide support portion, and the engaging portion is engaged with the locking portion. This connector system can achieve low back, prevent the cover from opening or flexing, and connect the FPC securely. However, the actual height of the connector on the printed circuit board is actually required to be 1.0 mm to 1.5 mm. Therefore, it is difficult to adopt a structure using the aforementioned sliding insulator, and a so-called NON-ZIF type connector has been disclosed. The NON-ZIF type connector is a two-piece connector that is installed inside the base insulator, and maintains the structure of the FPC by holding the front end of the FPC. Here, the base insulation system is formed of plastic of an insulating material. If the actual height of the NON-ZIF type connector is taken as 1.5 mm and the thickness of the FPC is taken as 0.3 mm, the FPC insertion opening of the connector will have a wall thickness of approximately 0.6 mm. In addition, if the actual height of the NON-ZIF type connector is taken as 1.0 mm and the thickness of the FPC is taken as 0.3 mm, the FPC insertion opening of the connector will have a wall thickness of approximately 0.35 mm. However, even if the base insulator is formed by using hard plastic to make the FPC insertion port a wall thickness of about 0.6 to 0.35 mm, there is still a problem that the base insulator is prone to cracks (cracks) when the FPC is inserted into the FPC insertion port of the connector. . [Summary of the Invention] The present invention is made to solve the above-mentioned problem, and an object thereof is to provide an FPC connector which can prevent the terminal of the socket housing even when the conductive portion of the FPC is slantly inserted into the terminal insertion port of the FPC connector. A crack (crack) was created at the insertion port 89814.doc 1233238. The inventors have invented a new type of FPC connector as follows in order to satisfy the above-mentioned object.

Here, the lengths of the upper adjustment pieces 62 and 72 in the length direction are shorter than the lengths of the embedment pieces 61 and 71 in the length direction. The embedding pieces 61 and 71 of the adjusting pieces 6 and 7 are press-fitted into the embedding holes 36 and 37 of the socket housing 3, respectively. At the same time, the upper adjusting pieces 62, 72 of the first adjusting pieces 6, 7 are inserted into the seat holes 34, 35 of the socket housing 3, and are arranged so as not to protrude from the surface of the socket body 3. Accordingly, as shown in FIG. 2B, the bottom surfaces of the embedding pieces 61 and 71 are exposed from the bottom surface of the socket housing 3 and are fixed on the printed circuit board 4 by welding. That is, as shown in FIG. 2B, the embedding piece 61 and the embedding piece 71 are oppositely disposed while sandwiching the terminal insertion opening 30 of the socket housing 3, and the upper adjustment piece 62 and the upper adjustment piece 72 and the printed circuit board 4 are sandwiching the terminal insertion opening. 30 ％。 Relative configuration.

Next, a procedure for inserting the FPC 2 into the connector 1 related to this embodiment mode will be described with reference to Figs. 4, 5A, and 5. FIG. 4 is a perspective view showing a state where the FPC 2 is inserted into the connector 1. FIG. 5A and 5B are sectional views showing a state in which the FPC 2 is inserted into the connector 1. FIG. While the conductive portion 2A of the FPC2 faces the connector 1 on the printed circuit board 4 upward, the FPC2 is inserted into the elastic holding portions 51A and 52A through the terminal insertion openings 30. Thereby, as shown in Figs. 5A and 5B, the conducting portion 2A of the FPC 2 is sandwiched by the elastic holding portions 51A and 52A. The above connector 1 has the following effects. The lower surface of the terminal insertion opening 30 side of the socket housing 3 is in contact with the upper surface of the printed circuit board 4. Therefore, even if the FPC2 is inserted obliquely downward at the end of the socket housing 3, 89814.doc -13-1233238 end insertion opening 30, the printed circuit board 4 can still support the socket housing 3, so the terminal insertion opening 30 does not crack. . Furthermore, since the two embedding pieces 61 and 71 are sandwiched between the terminal insertion openings 30, the socket housing 3 can be reliably fixed to the printed circuit board 4, and even if the FPC 2 is inserted obliquely into the terminal insertion openings 30, it can be prevented The terminal insertion opening 30 is widened in the width direction to generate a crack (crack). Furthermore, since the upper adjustment pieces 62, 72 and the printed circuit board 4 are arranged to sandwich the terminal insertion opening 30, even when the FPC2 is inserted into the terminal insertion opening 30 obliquely, the terminal insertion opening 30 can be prevented from expanding in the thickness direction and cracks ( Cracked). In addition, the edge in the thickness direction of the terminal insertion opening 30 in the socket housing 3 is defined by the lower front surface portion 14A and the upper front surface portion 14B having a specific thickness Lb L2 in the insertion direction of the FPC2. Further, the edge in the thickness direction of the terminal insertion opening 30 in the socket housing 3 is defined by the side surface portion 15. Therefore, the rigidity of the socket housing 3 can be improved, and cracks can be prevented from occurring in the terminal insertion port 30 with certainty. Moreover, as shown in FIG. 2B, since the upper adjustment pieces 62 and 72 are each arranged so as not to protrude from the upper surface of the socket housing 3, the height of the socket housing 3 can be made low, for example, the connector 1 can be installed The height is about 1.0 mm to 1.5 mm. The present invention has the following effects. A pair of adjustment pieces are mounted on both sides of the terminal insertion opening where cracks are likely to occur, and the pair of adjustment pieces are each mounted on a printed circuit board. Therefore, the socket case can be reliably fixed to the printed circuit board.
且，由於將2個埋設片夾住終端插入口配置，即使將FPC 89814.doc -14- 1233238 傾斜地插入終端插入口時，仍可防止終端插入口朝寬度方 向擴開而產生裂痕（龜裂）。 再者，由於將上部調整片和印刷基板夾住終端插入口配 置，即使將FPC傾斜地插入終端插入口時，仍可防止終端 插入口朝厚度方向擴開而產生裂痕（龜裂）。 且，由於使插座殼體之中規定終端插入口邊緣的部分， 在FPC之插入方向為特定厚度，因此可提高插座殼體之剛 性，進一步確實地防止終端插入口產生裂痕。 【圖式簡單說明】 圖1係表示本發明一實施型態相關之連接器及FPC之分 解立體圖。 圖2 A係前述實施型態相關之連接器之俯視圖。 圖2B係前述實施型態相關之連接器之前視圖。 圖2C係前述實施型態相關之連接器之側視圖。 圖2D係前述實施型態相關之連接器之後視圖。 圖2E係圖2B之X-X剖面圖。 圖2F係圖2B之Y-Y剖面圖。 圖3係形成在安裝前述實施型態相關之連接器之印刷基 板上面的圖案布局之模型圖。 圖4係表示將FPC插入前述實施型態相關之連接器的狀 態之立體圖。 圖5 A係表示將FPC插入前述實施型態相關之連接器的狀 態之剖面圖。 圖5B係表示將FPC插入前述實施型態相關之連接器的狀 89814.doc 15 1233238 態之剖面圖。 【圖式代表符號說明】 1 連接器 2 FPC 2A 導通部 3 插座殼體 4 印刷基板 6、Ί 調整片 11 下面部 12 壁部 13 上面部 14 正面部 14A 下側正面部 14B 上側正面部 15 側面部 16 背面部 30 終端插入口 34、35 座孔 36 - 37 埋入孑L 51 第1彈簧形接點 51A、52A 彈性挾持部 51B 、 52B 支持部 52 第2彈簧形接點 61、71 埋設片 -16- 89814.doc 1233238In addition, since the two embedded pieces are sandwiched between the terminal insertion openings, even when the FPC 89814.doc -14-1233238 is inserted obliquely, the terminal insertion openings can be prevented from expanding in the width direction and cracks (cracking) can be prevented. . Furthermore, since the upper adjustment piece and the printed circuit board are sandwiched between the terminal insertion openings, even when the FPC is inserted obliquely into the terminal insertion openings, it is possible to prevent the terminal insertion openings from expanding in the thickness direction and generate cracks (cracks). In addition, since the portion of the socket housing that defines the edge of the terminal insertion port has a specific thickness in the insertion direction of the FPC, the rigidity of the socket housing can be improved and cracks can be prevented from occurring at the terminal insertion port.
