Description

本発明は、フレキシブルプリント基板をリジッド基板（硬質基板）のコネクタに接続する際の誤挿入防止装置に関する。   The present invention relates to an erroneous insertion prevention device when a flexible printed board is connected to a connector of a rigid board (hard board).

例えばデジタルカメラにおいては、撮像素子が取り込んだ画像情報を撮像素子基板（第一のリジッド基板）で信号化し、この画像情報信号をフレキシブルプリント基板によってメイン基板（第二のリジッド基板）に送信する。このようなリジッド基板同士のコネクタをフレキシブルプリント基板で接続する際には、フレキシブルプリント基板の端子部（挿入端）をリジッド基板コネクタに挿入する作業が不可欠である。このフレキシブルプリント基板の組立（接続）作業は、自動化が困難であり、人の手によってリジッド基板のコネクタに接続されているのが実情である。   For example, in a digital camera, image information captured by an image sensor is converted into a signal by an image sensor substrate (first rigid substrate), and the image information signal is transmitted to a main substrate (second rigid substrate) by a flexible printed circuit board. When connecting connectors of such rigid boards with a flexible printed board, it is indispensable to insert a terminal portion (insertion end) of the flexible printed board into the rigid board connector. The assembly (connection) operation of the flexible printed circuit board is difficult to automate, and is actually connected to the connector of the rigid circuit board by a human hand.

特開２００７−１０９５６３号公報JP 2007-109563 A

フレキシブルプリント基板の端子部（挿入端）は一般に、単純な平板状をなしているため、表裏が逆でもリジッド基板コネクタに挿脱可能である。このため、表裏を間違って挿入したり、逆方向に挿入してしまうという問題があった。   Since the terminal portion (insertion end) of the flexible printed board generally has a simple flat plate shape, it can be inserted into and removed from the rigid board connector even when the front and back sides are reversed. For this reason, there was a problem that the front and back sides were inserted incorrectly or in the opposite direction.

特許文献１は、作業者の不注意によるコネクタの接続不良を防止するフレキシブルプリント基板の誤挿入防止装置として、フレキシブルプリント基板の端子部近傍に突起部を形成し、リジッドプリント基板及びこのリジッドプリント基板を真空吸着するステージ台に、コネクタに端子部が挿入されたフレキシブルプリント基板の突起部に対応する位置に位置する真空吸着孔と、 この真空吸着孔に真空漏れが生じているか否かを検知する真空圧力センサを設けている。コネクタにフレキシブルプリント基板の端子部が挿入接続されたとき、真空圧力センサの検知結果に基づき、突起部の真空吸着が完全である場合には硬質プリント基板の真空吸着固定を解除し、真空漏れが生じている場合には硬質プリント基板の真空吸着固定を維持することで、誤挿入を防止している。   Patent Document 1 discloses a rigid printed circuit board and a rigid printed circuit board, in which a protrusion is formed in the vicinity of a terminal portion of the flexible printed circuit board as a flexible printed circuit board erroneous insertion prevention device for preventing poor connection of a connector due to carelessness of an operator. The vacuum suction hole located at the position corresponding to the protrusion of the flexible printed circuit board with the terminal part inserted into the connector is detected on the stage base that vacuum-sucks the connector, and whether or not a vacuum leak has occurred in the vacuum suction hole is detected. A vacuum pressure sensor is provided. When the terminal part of the flexible printed circuit board is inserted and connected to the connector, if the vacuum suction of the protrusion is complete based on the detection result of the vacuum pressure sensor, the vacuum print fixing of the hard printed circuit board is released and the vacuum leak is When this occurs, the hard printed circuit board is maintained by vacuum suction fixing to prevent erroneous insertion.

この誤挿入防止装置はしかし、真空源を必要とし、装置が大がかりになるという問題がある。   However, this erroneous insertion preventing device requires a vacuum source and has a problem that the device becomes large.

本発明は、大がかりな設備を必要とせず、フレキシブルプリント基板の誤挿入を防止できる装置を得ることを目的とする。   An object of this invention is to obtain the apparatus which does not require a large-scale installation and can prevent misinsertion of a flexible printed circuit board.

本発明は、フレキシブルプリント基板の端子部をリジッド基板のコネクタに挿入して接続する基板接続装置において、上記フレキシブル基板を、上記コネクタへの挿入方向を含む平面視で非回転対称形状としたこと、及び上記リジッド基板または該リジッド基板を支持するベースに、上記リジッド基板コネクタに対する正規装着状態では上記フレキシブル基板に干渉せず、誤装着状態では干渉する誤挿入防止部材を設けたこと、を特徴としている。   The present invention provides a board connection device for connecting a terminal portion of a flexible printed circuit board by inserting it into a connector of a rigid circuit board, wherein the flexible circuit board has a non-rotationally symmetric shape in a plan view including an insertion direction to the connector, In addition, the rigid board or the base that supports the rigid board is provided with an erroneous insertion preventing member that does not interfere with the flexible board in a normal mounting state with respect to the rigid board connector but interferes in an erroneous mounting state. .

上記フレキシブルプリント基板は、その一実施形態では、一対のリジッド基板の上記コネクタに挿入される一対の平面部と、この一対の平面部とは該平面部と直交する方向に離間した底壁部と、該一対の平面部と底壁部を接続する接続壁部とを有しており、上記誤挿入防止部材は、非正規装着状態の上記底壁部に干渉する位置に設けられている。   In one embodiment, the flexible printed circuit board includes a pair of planar portions inserted into the connector of a pair of rigid substrates, and a pair of planar portions spaced from each other in a direction perpendicular to the planar portions. The connection wall portion connecting the pair of flat portions and the bottom wall portion is provided, and the erroneous insertion preventing member is provided at a position that interferes with the bottom wall portion in the irregularly mounted state.

上記フレキシブルプリント基板にはスリットを形成することができる。   A slit can be formed in the flexible printed circuit board.

上記誤挿入防止突起は、一実施形態では、断面Ｔ字型である。   In the embodiment, the erroneous insertion preventing protrusion has a T-shaped cross section.

本発明によるフレキシブルプリント基板の誤挿入防止装置は、フレキシブルプリント基板の端子部をリジッド基板のコネクタに挿入して接続する基板接続装置において、フレキシブル基板を非対称形状とし、リジッド基板または該リジッド基板を支持するベースに、リジッド基板コネクタに対する正規装着状態ではフレキシブル基板に干渉せず、誤装着状態では干渉する誤挿入防止部材を設けたので、単純な構成で、フレキシブルプリント基板の誤挿入を防止することができる。   An apparatus for preventing erroneous insertion of a flexible printed circuit board according to the present invention is a circuit board connection device for connecting a terminal portion of a flexible printed circuit board to a connector of a rigid circuit board. The flexible circuit board has an asymmetric shape and supports the rigid circuit board or the rigid circuit board. In order to prevent mis-insertion of the flexible printed circuit board with a simple configuration, the base is provided with a mis-insertion preventing member that does not interfere with the flexible circuit board in the regular mounting state with respect to the rigid board connector but interferes in the incorrect mounting state. it can.

図示実施形態は、図１に示すように、デジタルカメラの撮像素子基板（リジッド基板）１０とメイン基板（リジッド基板）２０をフレキシブルプリント基板３０で接続する装置に、本発明によるフレキシブルプリント基板の誤挿入防止装置を適用したものである。撮像素子基板１０とメイン基板２０は、デジタルカメラのボディベース（機枠）４０上に支持されていて、それぞれ、コネクタ１１とコネクタ２１が備えられており、このコネクタ１１とコネクタ２１に、フレキシブルプリント基板３０の両端部が挿入されている。基板１０とコネクタ１１、基板２０とコネクタ２１は、それぞれサーフェスマウントにより、一体に結合されている（図６参照）。   In the illustrated embodiment, as shown in FIG. 1, an error of a flexible printed circuit board according to the present invention is applied to an apparatus for connecting an image pickup device substrate (rigid substrate) 10 and a main substrate (rigid substrate) 20 of a digital camera with a flexible printed circuit board 30. An insertion prevention device is applied. The image pickup device substrate 10 and the main substrate 20 are supported on a body base (frame) 40 of the digital camera, and are provided with a connector 11 and a connector 21, respectively. Both ends of the substrate 30 are inserted. The substrate 10 and the connector 11, and the substrate 20 and the connector 21 are integrally coupled by a surface mount, respectively (see FIG. 6).

図３は、フレキシブルプリント基板３０の単体形状を示しており、一対の左右の平面部３１、３２と、この平面部３１、３２とは高さ位置（平面部３１、３２と直交する方向の位置）が異なる底壁部３３と、平面部３１、３２と底壁部３３を接続する接続壁部３４、３５を有している。平面部３１と３２の先端部には、コネクタ１１とコネクタ２１に挿脱される一対の平板状の端子部（挿入部）３１ａ、３２ａが形成されている。このフレキシブルプリント基板３０は、図３ないし図６に示すように、平面部３１と接続壁部３４の接続部、平面部３２と接続壁部３５の接続部、及び底壁部３３と接続壁部３４、３５の接続部の４箇所で鋭角に曲げられていて、変形が容易とされている。また、フレキシブルプリント基板３０には、底壁部３３から接続壁部３４、３５に跨らせてＺＸ平面方向のスリット３６が形成されていて、同様に、フレキシブルプリント基板３０をコネクタ１１とコネクタ２１に接続した際の反力を小さくする。   FIG. 3 shows a single shape of the flexible printed circuit board 30. The pair of left and right plane portions 31, 32 and the plane portions 31, 32 are at a height position (a position in a direction orthogonal to the plane portions 31, 32). ) Have different bottom wall portions 33 and connecting wall portions 34 and 35 connecting the flat surface portions 31 and 32 and the bottom wall portion 33. A pair of flat terminal portions (insertion portions) 31 a and 32 a that are inserted into and removed from the connector 11 and the connector 21 are formed at the tip portions of the flat portions 31 and 32. As shown in FIGS. 3 to 6, the flexible printed board 30 includes a connecting portion between the flat portion 31 and the connecting wall portion 34, a connecting portion between the flat portion 32 and the connecting wall portion 35, and a bottom wall portion 33 and the connecting wall portion. It is bent at an acute angle at four locations of the connecting portions 34 and 35, and is easily deformed. The flexible printed circuit board 30 is formed with slits 36 in the ZX plane direction extending from the bottom wall 33 to the connection wall sections 34 and 35. Similarly, the flexible printed circuit board 30 is connected to the connector 11 and the connector 21. Reduce reaction force when connected to.

以上のフレキシブルプリント基板３０の端子部３１ａ、３２ａは、それぞれ同一形状であり、コネクタ１１とコネクタ２１のそれぞれに挿脱可能である。従って、誤挿入の可能性がある。   The terminal portions 31 a and 32 a of the flexible printed circuit board 30 have the same shape, and can be inserted into and removed from the connector 11 and the connector 21. Therefore, there is a possibility of erroneous insertion.

この誤挿入を防止するため、フレキシブルプリント基板３０は、端子部３１ａと３２ａのコネクタ１１とコネクタ２１への挿入方向を含む平面視で、非回転対称形状とされている。より具体的には、図１、図３に示すようにＸＹＺの直交座標系を考えると、フレキシブルプリント基板３０の底壁部３３（及び接続壁部３４、３５）は、平面部３１と３２の中間位置Ｏに対してＹ方向（ＸＹ平面）形状が非対称であり、Ｙ方向の一端部に干渉突部３３Ｘが形成されている。フレキシブルプリント基板３０の平面部３１、３２、底壁部３３、及び接続壁部３４、３５も、詳細には回転中心Ｏに対して非対称であり、平面部３１と３２はＺ方向の高さ位置が異なっているが、本実施形態では、ＸＹ平面（端子部３１ａと３２ａのコネクタ１１とコネクタ２１への挿入平面）における底壁部３３（フレキシブルプリント基板３０）の非対称性を問題としている。   In order to prevent this erroneous insertion, the flexible printed circuit board 30 has a non-rotationally symmetric shape in a plan view including insertion directions of the terminal portions 31a and 32a into the connector 11 and the connector 21. More specifically, considering the XYZ orthogonal coordinate system as shown in FIGS. 1 and 3, the bottom wall portion 33 (and the connection wall portions 34 and 35) of the flexible printed circuit board 30 is formed by the planar portions 31 and 32. A shape in the Y direction (XY plane) is asymmetric with respect to the intermediate position O, and an interference projection 33X is formed at one end in the Y direction. In detail, the plane portions 31 and 32, the bottom wall portion 33, and the connection wall portions 34 and 35 of the flexible printed circuit board 30 are also asymmetric with respect to the rotation center O, and the plane portions 31 and 32 are at a height position in the Z direction. However, in this embodiment, the asymmetry of the bottom wall portion 33 (flexible printed circuit board 30) in the XY plane (the plane of insertion of the terminal portions 31a and 32a into the connector 11 and the connector 21) is a problem.

一方、ベース４０には、端子部３１ａがコネクタ１１に挿入され、端子部３２ａがコネクタ２１に挿入されるときには、底壁部３３の干渉突部３３Ｘと干渉することがなく（図１）、逆に端子部３１ａをコネクタ２１に挿入し、端子部３２ａをコネクタ１１に挿入しようとするときには（図２）、干渉突部３３Ｘと干渉する誤挿入防止突起（部材）４１が突出形成されている。この誤挿入防止突起４１は、平面Ｔ字状をしており、Ｚ方向に同一断面で突出している。このＴ字状の誤挿入防止突起４１は、図１に示すように、Ｚ方向から見たとき、Ｘ方向に長いＸ方向直線部４１Ｘと、このＸ方向直線部４１Ｘの中央部から、フレキシブルプリント基板３０の配置位置とは反対方向に延びるＹ方向直線部４１Ｙを有している。Ｘ方向直線部４１Ｘの長さは、フレキシブルプリント基板３０の底壁部３３のＸ方向の長さより若干短い程度（半分以上）であり、Ｙ方向直線部４１Ｙは、誤挿入防止突起４１全体の強度を確保しつつ、他の部品（部材）の配置や組立に与える影響が少ないように設置面積を小さくしている。また、誤挿入防止突起４１のＺ方向の高さは、方向を間違えたフレキシブルプリント基板３０の底壁部３３の干渉突部３３Ｘを十分変形させるように定められている。   On the other hand, in the base 40, when the terminal portion 31a is inserted into the connector 11 and the terminal portion 32a is inserted into the connector 21, the base 40 does not interfere with the interference projection 33X of the bottom wall portion 33 (FIG. 1). When the terminal portion 31a is inserted into the connector 21 and the terminal portion 32a is to be inserted into the connector 11 (FIG. 2), an erroneous insertion prevention protrusion (member) 41 that interferes with the interference protrusion 33X is formed to protrude. The erroneous insertion preventing protrusion 41 has a planar T shape and protrudes in the same cross section in the Z direction. As shown in FIG. 1, the T-shaped erroneous insertion preventing protrusion 41 has an X-direction straight portion 41 </ b> X that is long in the X-direction and a central portion of the X-direction straight portion 41 </ b> X when viewed from the Z-direction. The Y-direction linear portion 41Y extends in the direction opposite to the position where the substrate 30 is disposed. The length of the X-direction straight portion 41X is slightly shorter (half or more) than the length of the bottom wall portion 33 of the flexible printed circuit board 30 in the X direction. The Y-direction straight portion 41Y is the strength of the erroneous insertion preventing protrusion 41 as a whole. The installation area is reduced so as to reduce the influence on the arrangement and assembly of other components (members). Further, the height in the Z direction of the erroneous insertion preventing projection 41 is determined so as to sufficiently deform the interference projecting portion 33X of the bottom wall portion 33 of the flexible printed board 30 having the wrong direction.

以上のフレキシブルプリント基板の誤挿入防止装置は、フレキシブルプリント基板３０の向きが正しいときには、図１のように、フレキシブルプリント基板３０の干渉突部３３Ｘは、ベース４０上の誤挿入防止突起４１と干渉することはなく、平面部３１の端子部３１ａと平面部３２の端子部３２ａを正しくコネクタ１１とコネクタ２１に挿入することができる。この挿入状態（正規接続状態）では、撮像素子基板１０上の撮像素子１２（図６）が画像情報を取り込み、撮像素子基板１０でその画像情報が信号化され、フレキシブルプリント基板３０によって画像情報の信号がメイン基板２０に伝えられる。   In the above-described flexible printed circuit board misinsertion prevention apparatus, when the orientation of the flexible printed circuit board 30 is correct, the interference projection 33X of the flexible printed circuit board 30 interferes with the erroneous insertion prevention projection 41 on the base 40 as shown in FIG. The terminal part 31a of the plane part 31 and the terminal part 32a of the plane part 32 can be correctly inserted into the connector 11 and the connector 21. In this insertion state (normal connection state), the image sensor 12 (FIG. 6) on the image sensor substrate 10 captures image information, the image information is signaled by the image sensor substrate 10, and the flexible printed circuit board 30 stores the image information. A signal is transmitted to the main board 20.

一方、フレキシブルプリント基板３０の向きを１８０゜間違えたときには、図２（あるいは図５、図６）に示すように、底壁部３３の干渉突部３３Ｘが誤挿入防止突起４１と干渉する。このため、端子部３１ａをコネクタ２１に、端子部３２ａをコネクタ１１にそれぞれ挿入することができない（図２は図示の便宜上フレキシブルプリント基板３０の両端端子部をコネクタ１１と２１に挿入したように描いているが実際には挿入できない）。仮に、フレキシブルプリント基板３０の柔軟性により、端子部３１ａをコネクタ２１に、端子部３２ａをコネクタ１１に挿入することが可能であったとしても、作業者は、底壁部３３の非対称形状及び誤挿入防止突起４１によって与えられる不自然な反力により方向の間違いに容易に気づく。前述のように、誤挿入防止突起４１のＺ方向の高さは、誤挿入ができないように、あるいは誤挿入に容易に気づくように設定されているる。別言すると、フレキシブルプリント基板３０の柔軟性（ばね定数）は、平面部３１、３２と、底壁部３３と、接続壁部３４、３５による巾着状断面形状と、スリット３６の数と大きさにより調整することができ、誤挿入防止突起４１と干渉したときの誤挿入の認識（変形抵抗）が得られるように定めることができる。誤挿入防止突起４１（のＸ方向直線部４１Ｘ）は、フレキシブルプリント基板３０の底壁部３３のＸ方向の幅の半分以上に当接するから、誤挿入を確実に防止し、あるいは作業者が方向の間違いに容易に気づく。   On the other hand, when the orientation of the flexible printed circuit board 30 is changed by 180 °, the interference projection 33X of the bottom wall portion 33 interferes with the erroneous insertion prevention projection 41 as shown in FIG. 2 (or FIGS. 5 and 6). For this reason, the terminal portion 31a cannot be inserted into the connector 21 and the terminal portion 32a cannot be inserted into the connector 11 (FIG. 2 is drawn as if both terminal portions of the flexible printed circuit board 30 were inserted into the connectors 11 and 21 for convenience of illustration. But can't actually insert). Even if it is possible to insert the terminal portion 31 a into the connector 21 and the terminal portion 32 a into the connector 11 due to the flexibility of the flexible printed circuit board 30, the operator may have an asymmetric shape and an error in the bottom wall portion 33. Due to the unnatural reaction force provided by the insertion prevention protrusion 41, the wrong direction is easily noticed. As described above, the height in the Z direction of the erroneous insertion preventing protrusion 41 is set so as to prevent erroneous insertion or to easily recognize erroneous insertion. In other words, the flexibility (spring constant) of the flexible printed circuit board 30 is determined by the width of the flat portions 31 and 32, the bottom wall 33, and the purse-like cross-sectional shape of the connection walls 34 and 35, and the number and size of the slits 36. And can be determined so as to obtain recognition (deformation resistance) of erroneous insertion when it interferes with the erroneous insertion prevention protrusion 41. The erroneous insertion prevention protrusion 41 (the X-direction linear portion 41X) abuts more than half of the width in the X direction of the bottom wall portion 33 of the flexible printed circuit board 30, so that erroneous insertion is reliably prevented or the direction of the operator is Easily notice the mistakes.

フレキシブルプリント基板３０に、底壁部３３から接続壁部３４、３５に跨らせて形成したスリット３６は該基板３０の変形を容易にし、平面部３１と接続壁部３４の接続部、３２と３５の接続部、及び底壁部３３と接続壁部３４、３５の接続部の４箇所で鋭角に曲折した曲折構造もスリット３６と同様に変形を容易にする。   The slit 36 formed on the flexible printed circuit board 30 from the bottom wall portion 33 to the connection wall portions 34, 35 facilitates deformation of the substrate 30, and connects the flat portion 31 and the connection portions 32, 32 of the connection wall portion 34, Similarly to the slit 36, the bent structure which is bent at an acute angle at the four connecting portions 35 and the connecting portion between the bottom wall portion 33 and the connecting wall portions 34 and 35 facilitates deformation.

以上の説明では、撮像素子基板１０とメイン基板２０をリジッド基板（硬質基板）と説明したが、「リジッド（硬質）」は、単にフレキシブルプリント基板と比較して「硬質」であるとの意である。   In the above description, the imaging device substrate 10 and the main substrate 20 are described as rigid substrates (hard substrates). However, “rigid” is simply “hard” compared to a flexible printed circuit board. is there.

また以上の実施形態では、ベース４０に誤挿入防止突起４１を一体に設けたが、別体として誤挿入防止突起をベースに装着し、あるいは誤挿入防止突起をリジッド基板１０またはメイン基板２０に一体に設ける態様も可能である。   In the above embodiment, the erroneous insertion preventing protrusion 41 is integrally provided on the base 40. However, the erroneous insertion preventing protrusion is separately attached to the base, or the erroneous insertion preventing protrusion is integrally formed on the rigid board 10 or the main board 20. It is also possible to provide an embodiment.
