Description

本発明は、メモリーモジュールなどのサブ基板をメイン基板に接続するために用いられるコネクタに関し、更に詳しくは、挿入されたサブ基板をコネクタより排出させるための排出機構に関する。   The present invention relates to a connector used for connecting a sub board such as a memory module to a main board, and more particularly to a discharge mechanism for discharging an inserted sub board from the connector.

基板同士を接続するコネクタは従来知られており、一方の基板(メイン基板と称する)に固定されて他方の基板(サブ基板と称する)を受容する受容溝を有したハウジングと、このハウジングに保持されてメイン基板上の配線パターンと繋がる複数のコンタクトとから構成されている。メイン基板に接続されるサブ基板としてはメモリーモジュールやインターフェースカード、ICカードなどが知られており、メイン基板に挿入される端部にはコネクタのコンタクトと接触する端子がコンタクトの配列に対応して整列配置されている。サブ基板はコネクタのハウジングに形成された受容溝内に挿着され、この状態においてコネクタ側のコンタクトとサブ基板側の端子とが接触するようになっている。   2. Description of the Related Art A connector for connecting boards to each other is conventionally known. A housing having a receiving groove fixed to one board (referred to as a main board) and receiving the other board (referred to as a sub board), and held in the housing. And a plurality of contacts connected to the wiring pattern on the main board. Memory modules, interface cards, IC cards, etc. are known as sub-boards connected to the main board, and terminals that contact the connector contacts correspond to the contact arrangement at the end inserted into the main board. Aligned. The sub board is inserted into a receiving groove formed in the housing of the connector, and in this state, the contact on the connector side and the terminal on the sub board side come into contact with each other.

サブ基板のコネクタからの排出は、ハウジングの両端部に設けられた2つのレバー部材を操作して行われる。各レバー部材はその中間部がハウジングに枢支されたシーソーのような構成となっており、一方側の端部に形成された操作部をサブ基板のハウジングへの挿入方向に押圧するとレバー部材全体が枢支部を中心として揺動し、他方側の端部に形成された押圧部がこれとは反対の方向に移動してサブ基板をハウジングから押し出す(排出する)ようになっている(例えば下記の特許文献参照)。
特開2000−91032号公報 特開平8−148223号公報
The sub-board is discharged from the connector by operating two lever members provided at both ends of the housing. Each lever member has a structure like a seesaw whose middle part is pivotally supported by the housing. When the operation part formed at one end is pressed in the insertion direction of the sub-board into the housing, the entire lever member Oscillates around the pivot, and the pressing portion formed at the other end moves in the opposite direction to push out (discharge) the sub-board from the housing (for example, the following) In the patent literature).
JP 2000-91032 A JP-A-8-148223

しかしながら、上記従来のコネクタでは、サブ基板の排出操作時には2つのレバー部材の操作部はレバー部材全体の揺動によって互いに離間するように移動するため、2つのレバー部材の片手による同時操作は行いにくく、安全のため両手を用いて行う必要があった。また、サブ基板をハウジングより排出させる際、レバー部材の操作力が大き過ぎた場合には、その操作部や枢支部を破損させてしまうおそれがあった。   However, in the conventional connector, when the sub-board is ejected, the operation portions of the two lever members move away from each other by swinging the entire lever member, so that simultaneous operation with one hand of the two lever members is difficult to perform. It was necessary to use both hands for safety. Further, when the operation force of the lever member is excessively large when the sub-board is discharged from the housing, there is a possibility that the operation portion or the pivot portion is damaged.

本発明はこのような問題に鑑みてなされたものであり、サブ基板を排出させる2つのレバー部材の同時操作を片手で行うことができるようにし、サブ基板の排出操作性を向上させることができるようにしたコネクタを提供することを目的としている。また、レバー部材の操作力が過大であった場合でもその操作部や枢支部を破損させるおそれのない構成のコネクタを提供することを目的としている。   The present invention has been made in view of such a problem, and enables simultaneous operation of two lever members for discharging a sub board with one hand, thereby improving the discharge operability of the sub board. An object of the present invention is to provide such a connector. It is another object of the present invention to provide a connector having a configuration that does not cause damage to the operation part and the pivotal support part even when the operation force of the lever member is excessive.

本発明に係るコネクタは、第1の基板(例えば、実施形態におけるメイン基板50)に取り付けられ、第1の基板と接続される第2の基板(例えば、実施形態におけるサブ基板60)を受容する受容溝を有したハウジングと、ハウジングに保持され、ハウジングの受容溝内に挿入された第2の基板の端子と接触するコンタクトと、ハウジングにおける受容溝の延びる方向の両端部に取り付けられて第2の基板のハウジングに対する挿脱面と平行な面内で揺動自在な2つのレバー部材とを有し、これら2つのレバー部材の各々はハウジングに枢支されたアーム部及びアーム部と連結してハウジングにおける受容溝の延びる方向の端部の外方に位置した操作部からなっており、第2の基板がハウジングの受容溝内に挿入されている状態から2つのレバー部材の操作部を互いに近づく方向に押圧操作したとき、前記2つのレバー部材それぞれのアーム部が揺動して、操作部とアーム部の揺動中心(例えば、実施形態における枢支円孔32a)との間に形成された押圧部が第2の基板をハウジングから排出させる方向に押圧し、これにより第2の基板がハウジングより排出されるようになっている。   The connector according to the present invention is attached to a first board (for example, the main board 50 in the embodiment) and receives a second board (for example, the sub board 60 in the embodiment) connected to the first board. A housing having a receiving groove; a contact held by the housing and in contact with a terminal of the second substrate inserted into the receiving groove of the housing; and a second attached to both ends of the housing in the extending direction of the receiving groove. Two lever members swingable in a plane parallel to the insertion / removal surface of the substrate with respect to the housing, and each of the two lever members is connected to an arm portion and an arm portion pivotally supported by the housing. Two levers from a state in which the second board is inserted into the receiving groove of the housing, the operating part being located outside the end of the receiving groove extending in the housing. When the operation portion of the member is pressed in a direction approaching each other, the arm portions of the two lever members swing, and the swing center of the operation portion and the arm portion (for example, the pivotal support hole 32a in the embodiment). Is pressed in the direction in which the second substrate is discharged from the housing, whereby the second substrate is discharged from the housing.

上記コネクタでは、第2の基板がハウジングの受容溝内に挿入されている状態から2つのレバー部材の操作部を押圧操作したとき、これら操作部は第2の基板がハウジングから排出された時点でハウジングに当接するようになっていることが好ましい。また、第2の基板がハウジングの受容溝内に挿入されたとき、ハウジングに設けられた係止突起が第2の基板に形成された被係止凹部(例えば、実施形態における被係止孔62)に嵌入して第2の基板がハウジング内にロックされるようになっており、第2の基板がハウジングの受容溝内に挿入されている状態から2つのレバー部材の操作部を押圧操作したとき、2つのレバー部材それぞれの操作部から延びて設けられたロック解除部(ロック解除突起34)が係止突起を第2の基板の面外方向に移動させてハウジングの第2の基板に対するロックを解除させるようになっていることが好ましい。   In the above connector, when the operation parts of the two lever members are pressed from the state where the second board is inserted into the receiving groove of the housing, these operation parts are at the time when the second board is ejected from the housing. It is preferable to contact the housing. In addition, when the second substrate is inserted into the receiving groove of the housing, the locking protrusion provided on the housing has a locked recess formed in the second substrate (for example, the locked hole 62 in the embodiment). ) And the second board is locked in the housing, and the operation parts of the two lever members are pressed from the state where the second board is inserted into the receiving groove of the housing. At this time, the unlocking portion (unlocking projection 34) provided extending from the operation portion of each of the two lever members moves the locking projection in the out-of-plane direction of the second substrate to lock the housing with respect to the second substrate. Is preferably canceled.

本発明に係るコネクタでは、第2の基板がハウジングの受容溝内に挿入されている状態からハウジングの両端部に取り付けられた2つのレバー部材の操作部を互いに近づく方向に押圧操作すると、2つのレバー部材それぞれのアーム部が揺動して、操作部とアーム部の揺動中心との間に形成された押圧部が第2の基板をハウジングから排出させる方向に押圧し、これにより第2の基板がハウジングの受容溝より排出されるようになっている。このように本発明に係るコネクタでは、ハウジングの両端部に設けられて第2の基板の排出時に押圧操作される2つのレバー部材が、従来のようにその操作部同士が遠ざかる方向ではなく、操作部同士が近づく方向に揺動するので、これら2つのレバー部材の同時操作を片手で行うことができ、第2の基板の排出操作性を向上させることができる。   In the connector according to the present invention, when the second board is inserted into the receiving groove of the housing and the operation portions of the two lever members attached to the both end portions of the housing are pressed in a direction approaching each other, The arm portion of each lever member swings, and the pressing portion formed between the operating portion and the swing center of the arm portion presses the second substrate in the direction of discharging from the housing, whereby the second portion The substrate is discharged from the receiving groove of the housing. As described above, in the connector according to the present invention, the two lever members provided at both ends of the housing and operated to be pressed when the second board is ejected are not operated in the direction in which the operation units move away from each other as in the conventional case. Since the parts swing in the direction in which they approach each other, the two lever members can be operated simultaneously with one hand, and the discharge operability of the second substrate can be improved.

また、本発明に係るコネクタでは、第2の基板がハウジングの受容溝内に挿入されている状態から2つのレバー部材の操作部を押圧操作したとき、これら操作部が、第2の基板がハウジングから排出された時点でハウジングに当接するようになっているのであれば、レバー部材の操作力が過大であった場合でもその操作部や枢支部を破損させるおそれがない。更に、第2の基板がハウジングの受容溝内に挿入されたとき、ハウジングに設けられた係止突起が第2の基板に形成された被係止凹部に嵌入して第2の基板がハウジング内にロックされるようになっており、第2の基板がハウジングの受容溝内に挿入されている状態から2つのレバー部材の操作部を押圧操作したとき、2つのレバー部材それぞれの操作部から延びて設けられたロック解除部が上記係止突起を第2の基板の面外方向に移動させてハウジングの第2の基板に対するロックを解除させるようになっているのであれば、第2の基板のハウジングへのロック及びその解除を行う構成は簡易なものとなり、製造コストの低減に資することができる。   Further, in the connector according to the present invention, when the operation portions of the two lever members are pressed from the state in which the second substrate is inserted into the receiving groove of the housing, these operation portions are used as the second substrate is the housing. If the lever comes into contact with the housing at the time when the lever is discharged, there is no possibility of damaging the operation portion and the pivot portion even when the operation force of the lever member is excessive. Further, when the second substrate is inserted into the receiving groove of the housing, the locking protrusion provided on the housing is fitted into the locked recess formed on the second substrate, and the second substrate is inserted into the housing. When the operation parts of the two lever members are pressed from the state where the second substrate is inserted into the receiving groove of the housing, the two lever members extend from the operation parts. If the unlocking portion provided in the above-mentioned manner moves the locking projection in the out-of-plane direction of the second substrate to release the lock on the second substrate of the housing, The structure for locking and releasing the housing is simple and can contribute to the reduction of the manufacturing cost.

サブ基板60のコネクタ1への挿着は、サブ基板60の先端部(上述のように端子64が設けられた側の端部)をハウジング10の受容溝14内に上方から挿入することにより行う(図1及び図3参照)。このときサブ基板60はハウジング10の左右端部に設けられた2つのガイド部16によって受容溝14内に導かれる。サブ基板60が受容溝14内に入ると、サブ基板60の端子64はコネクタ1のコンタクト40の接触部42を押し退けて(弾性的に撓ませて)進み、サブ基板60の先端部がハウジング10の後壁12に形成された段差部からなるストッパ22(図3及び図6(A)参照)に上方から当接したところでサブ基板60のハウジング10内への挿入が完了する。このサブ基板60のハウジング10内への挿入が完了した時点では、図6に示すように、コネクタ1側の各コンタクト40の接触部42はサブ基板60側の各端子64に適当な接触圧をもって接触する。また、このサブ基板60のハウジング10内への挿入によって、コンタクト1に設けられた図示しない電源スイッチがオンとなる。このような状態では、サブ基板60はコネクタ1を介してメイン基板50と電気的に接続された状態となり、サブ基板60とメイン基板50との間では信号の伝送が可能となる。   The sub-board 60 is inserted into the connector 1 by inserting the tip of the sub-board 60 (the end on the side where the terminal 64 is provided as described above) into the receiving groove 14 of the housing 10 from above. (See FIGS. 1 and 3). At this time, the sub-board 60 is guided into the receiving groove 14 by the two guide portions 16 provided at the left and right ends of the housing 10. When the sub-board 60 enters the receiving groove 14, the terminal 64 of the sub-board 60 advances by pushing away the contact portion 42 of the contact 40 of the connector 1 (elastically bent), and the tip of the sub-board 60 is moved to the housing 10. The insertion of the sub-board 60 into the housing 10 is completed when it comes into contact with the stopper 22 (see FIGS. 3 and 6A) formed of a stepped portion formed on the rear wall 12 from above. When the insertion of the sub board 60 into the housing 10 is completed, as shown in FIG. 6, the contact portions 42 of the contacts 40 on the connector 1 side have appropriate contact pressures on the terminals 64 on the sub board 60 side. Contact. Further, when the sub board 60 is inserted into the housing 10, a power switch (not shown) provided on the contact 1 is turned on. In such a state, the sub board 60 is in a state of being electrically connected to the main board 50 via the connector 1, and signal transmission is possible between the sub board 60 and the main board 50.

ここで、サブ基板60がハウジング10に対して正しい向きで挿入された場合には、ベース部材61の先端部に形成された切り欠き部63と、ハウジング10の受容溝14内に上方に突出して延びて設けられた誤挿入防止突起23(図1及び図2参照)とが嵌合するようになっている。ここで、切り欠き部63及び誤挿入防止突起23はそれぞれサブ基板60若しくはハウジング10の左右方向中心部よりも左右方向にずれた位置に設けられているため、サブ基板60がハウジング10に対して正しい向きで挿入されなかった場合には、切り欠き部63と誤挿入防止突起23とは嵌合せず、サブ基板60のハウジング10内への挿入は不能となる。すなわち、切り欠き部63と誤挿入防止突起23とによってサブ基板60のハウジング10への誤挿入が防止されるようになっている。   Here, when the sub-board 60 is inserted in the correct orientation with respect to the housing 10, it projects upward into the notch 63 formed at the tip of the base member 61 and the receiving groove 14 of the housing 10. The extension insertion prevention protrusion 23 (refer FIG.1 and FIG.2) provided by extending is fitted. Here, since the notch 63 and the erroneous insertion preventing projection 23 are provided at positions shifted in the left-right direction from the center of the sub-board 60 or the housing 10 in the left-right direction, the sub-board 60 is located with respect to the housing 10. If it is not inserted in the correct orientation, the notch 63 and the erroneous insertion preventing projection 23 are not fitted, and the sub board 60 cannot be inserted into the housing 10. In other words, the notch 63 and the erroneous insertion preventing projection 23 prevent the erroneous insertion of the sub board 60 into the housing 10.

また、サブ基板60がハウジング10内に挿入されると、サブ基板60のベース部61はハウジング10の係止突起支持部17に形成された係止突起18を押し退けて進むので、係止突起支持部17はサブ基板60の面外方向に撓み変形するが、サブ基板60がハウジング10内に正常に挿着されたときには、係止突起18がサブ基板60の左右両端に設けられた被係止孔62に嵌入する。ここで、図3に示すように、被係止突起18はその上面が傾斜面となっているが、下面はこのような傾斜面とはなっていないので、係止突起18が被係止孔62内に嵌入した状態では、サブ基板60を上方に引っ張ってもハウジング10から抜けることはない。すなわち、被係止突起18が被係止孔62内に嵌入することによってサブ基板60はハウジング10内にロックされる。   Further, when the sub board 60 is inserted into the housing 10, the base portion 61 of the sub board 60 moves away from the locking protrusion 18 formed on the locking protrusion support portion 17 of the housing 10, so that the locking protrusion support is supported. The portion 17 bends and deforms in the out-of-plane direction of the sub-board 60, but when the sub-board 60 is normally inserted into the housing 10, the locking protrusions 18 are provided at the left and right ends of the sub-board 60. Fit into the hole 62. Here, as shown in FIG. 3, the upper surface of the locked projection 18 is an inclined surface, but the lower surface is not such an inclined surface. In the state of being fitted in 62, even if the sub-board 60 is pulled upward, it will not come out of the housing 10. That is, the sub-board 60 is locked in the housing 10 by fitting the locked protrusion 18 into the locked hole 62.

ハウジング10内に挿着された状態のサブ基板60をハウジング10から排出させるには、ハウジング10の左右端部に設けられた2つのレバー部材30の操作部31を互いに近づく方向に押圧操作すればよい。具体的には、2つのレバー部材30の操作部31を片手で摘まみ上げるようにする。これにより2つのレバー部材30,30のアーム部32はその揺動中心(枢支円孔32a)を中心に上方へ揺動し、各レバー部材30に設けられた押圧部33がサブ基板60の先端部を上方へ押し上げる(図7(B)参照)。これによりサブ基板60はハウジング10の受容溝14より排出される。また、このような2つのレバー部材30,30の揺動によって、各レバー部材30に設けられた2つのロック解除突起34,34はガイド部支持部15と係止突起支持部17との間の空間20内に入り込むが、このとき係止突起支持部17側に位置するロック解除突起34はその傾斜面34a(図4参照)において係止突起支持部17を外側(ハウジング10の前方)に押圧してこれを撓み変形させるので、係止突起18はサブ基板60の面外方向(ハウジング10の前方)に移動することとなり、サブ基板60の被係止孔62から離脱するので、ハウジング10のサブ基板60に対するロックが解除される。このような状態となれば、サブ基板60を指で摘んでハウジング10より抜き去ることができる。なお、各レバー部材30の操作部31はサブ基板60がハウジング10から排出された時点でその上端当接部31bがハウジング10のガイド部16の当接面16aに当接するようになっており、レバー部材30の揺動範囲はサブ基板60がハウジング10から排出されたところまでに制限される。   In order to eject the sub-board 60 inserted in the housing 10 from the housing 10, the operation portions 31 of the two lever members 30 provided at the left and right end portions of the housing 10 are pressed in a direction approaching each other. Good. Specifically, the operation portions 31 of the two lever members 30 are picked up with one hand. As a result, the arm portions 32 of the two lever members 30, 30 swing upward about the swing center (the pivotal support hole 32 a), and the pressing portion 33 provided on each lever member 30 is moved to the sub-board 60. The tip is pushed upward (see FIG. 7B). As a result, the sub-board 60 is discharged from the receiving groove 14 of the housing 10. Further, due to the swinging of the two lever members 30, 30, the two unlocking projections 34, 34 provided on each lever member 30 are located between the guide portion support portion 15 and the locking projection support portion 17. At this time, the unlocking projection 34 located on the locking projection support portion 17 side presses the locking projection support portion 17 outward (in front of the housing 10) on the inclined surface 34a (see FIG. 4). Since this is bent and deformed, the locking projection 18 moves in the out-of-plane direction of the sub-board 60 (in front of the housing 10) and is detached from the locked hole 62 of the sub-board 60. The lock on the sub-board 60 is released. In such a state, the sub-board 60 can be grasped with a finger and removed from the housing 10. The operation portion 31 of each lever member 30 is configured such that the upper end contact portion 31b contacts the contact surface 16a of the guide portion 16 of the housing 10 when the sub board 60 is discharged from the housing 10. The swing range of the lever member 30 is limited to the point where the sub board 60 is discharged from the housing 10.

このように本コネクタ1では、サブ基板60がハウジング10の受容溝14内に挿入されている状態からハウジング10の両端部に取り付けられた2つのレバー部材30,30の操作部31を互いに近づく方向に押圧操作すると、2つのレバー部材30,30それぞれのアーム部32が揺動して、操作部31とアーム部32の揺動中心(枢支円孔32a)との間に形成された押圧部33がサブ基板60をハウジング10から排出させる方向に押圧し、これによりサブ基板60がハウジング10の受容溝14より排出されるようになっている。このように本コネクタ1では、ハウジング10の両端部に設けられてサブ基板60の排出時に押圧操作される2つのレバー部材30,30が、従来のようにその操作部同士が遠ざかる方向ではなく、操作部31同士が近づく方向に揺動するので、これら2つのレバー部材30,30の同時操作を片手で行うことができ、サブ基板60の排出操作性を向上させることができる。   As described above, in the present connector 1, the operation portions 31 of the two lever members 30 and 30 attached to both ends of the housing 10 are brought closer to each other from the state in which the sub board 60 is inserted into the receiving groove 14 of the housing 10. When the pressing operation is performed, the arm portion 32 of each of the two lever members 30 and 30 swings, and a pressing portion formed between the operating portion 31 and the swing center (the pivotal circular hole 32a) of the arm portion 32. 33 presses the sub board 60 in the direction of discharging from the housing 10, whereby the sub board 60 is discharged from the receiving groove 14 of the housing 10. Thus, in this connector 1, the two lever members 30, 30 provided at both ends of the housing 10 and operated to be pressed when the sub-board 60 is ejected are not in a direction in which the operation units move away from each other as in the related art. Since the operating portions 31 are swung in a direction in which they approach each other, the two lever members 30 and 30 can be operated simultaneously with one hand, and the discharge operability of the sub-board 60 can be improved.

また、本コネクタ1では、サブ基板60がハウジング10の受容溝14内に挿入されている状態から2つのレバー部材30,30の操作部31を押圧操作したとき、これら操作部31が、サブ基板60がハウジング10から排出された時点でハウジング10に(具体的にはガイド部16の当接面16aに)当接するようになっているので、レバー部材30の操作力が過大であった場合でもその操作部31や枢支部(具体的には枢支突起19)を破損させるおそれがない。   In the connector 1, when the operation parts 31 of the two lever members 30 and 30 are pressed from the state in which the sub board 60 is inserted into the receiving groove 14 of the housing 10, the operation parts 31 are moved to the sub board. When 60 is discharged from the housing 10, it contacts the housing 10 (specifically, the contact surface 16 a of the guide portion 16), so even if the operating force of the lever member 30 is excessive. There is no possibility of damaging the operation portion 31 or the pivot portion (specifically, the pivot projection 19).

更に本コネクタ1では、サブ基板60がハウジング10の受容溝14内に挿入されたとき、ハウジング10に(係止突起支持部17に)設けられた係止突起18がサブ基板60に形成された被係止孔62に嵌入してサブ基板60がハウジング10内にロックされるようになっており、サブ基板60がハウジング10の受容溝14内に挿入されている状態から2つのレバー部材30,30の操作部31を押圧操作したとき、2つのレバー部材30,30それぞれの操作部31から延びて設けられたロック解除部33が上記係止突起18をサブ基板60の面外方向に移動させてハウジング10のサブ基板60に対するロックを解除させるようになっている。このように本コネクタ1では、サブ基板60のハウジング10へのロック及びその解除を行う構成が簡易であるので、製造コストの低減に資することができる。   Further, in the connector 1, when the sub board 60 is inserted into the receiving groove 14 of the housing 10, the locking protrusion 18 provided on the housing 10 (on the locking protrusion support portion 17) is formed on the sub board 60. The sub-board 60 is inserted into the locked hole 62 and locked in the housing 10, and the two lever members 30, from the state in which the sub-board 60 is inserted into the receiving groove 14 of the housing 10, When the operation part 31 of 30 is pressed, the lock release part 33 provided extending from the operation part 31 of each of the two lever members 30 and 30 moves the locking projection 18 in the out-of-plane direction of the sub-board 60. Thus, the lock on the sub-board 60 of the housing 10 is released. Thus, in this connector 1, since the structure which locks to the housing 10 of the sub board | substrate 60 and the cancellation | release is simple, it can contribute to reduction of manufacturing cost.

これまで本発明の好ましい実施形態について説明してきたが、本発明の範囲は上述の実施形態において示したものに限定されない。例えば、上述の実施形態では、コネクタ1はその受容溝14の延びる方向がメイン基板50に対して垂直方向となるようにメイン基板50に取り付けられていたが、受容溝の延びる方向がメイン基板50に対して平行となるように取り付けられるものであっても。また、上述の実施形態においては、サブ基板60がハウジング10内に正常に挿着されたとき、ハウジング10に形成された係止突起18がサブ基板60に形成された被係止孔62内に嵌入するようになっていたが、この被係止孔62は孔でなくても凹部であればよい。   Although the preferred embodiments of the present invention have been described so far, the scope of the present invention is not limited to those shown in the above-described embodiments. For example, in the above-described embodiment, the connector 1 is attached to the main board 50 so that the extending direction of the receiving groove 14 is perpendicular to the main board 50. However, the extending direction of the receiving groove is the main board 50. Even if it is attached so as to be parallel to. Further, in the above-described embodiment, when the sub-board 60 is normally inserted into the housing 10, the locking protrusions 18 formed on the housing 10 are in the locked holes 62 formed on the sub-board 60. Although the fitting hole 62 is not a hole, it may be a recess.
