Description

本発明は、光コネクタプラグの高密度実装において、パネルのアダプタ取付孔に対する光コネクタ用アダプタのガタ止め機構に関する。 The present invention relates to a mechanism for preventing backlash of an optical connector adapter with respect to a panel adapter mounting hole in high-density mounting of an optical connector plug.

従来、光コネクタプラグの高密度実装における光コネクタ用の例えばＭＰＯのアダプタ本体１００をパネルのアダプタ取付孔に取り付ける場合、図１６乃至図２０に示すように、該アダプタ本体１００の一方の挿入用開口端１０１ａ側の上下左右の各対称部位に切り起こし状の爪片によるラッチレバー１０３を設けたスナップイン方式を採っている。 Conventionally, when the adapter body 100 of, for example, an MPO for an optical connector for high-density mounting of an optical connector plug is attached to an adapter mounting hole of a panel, as shown in FIGS. 16 to 20, one opening for inserting the adapter body 100 is used. A snap-in method is adopted in which a latch lever 103 with a raised claw piece is provided at each symmetrical portion of the top, bottom, left, and right on the end 101a side.

すなわち、アダプタ本体１００の具体的な構成としては、図１６乃至図２０に示すように、ＭＰＯ型コネクタプラグのフェルールの光ファイバテープ心線を相互接続できるように、当該アダプタ本体１００の両端に、光学軸が一致するようにして、一方の挿入用開口端１０１ａと、他方の挿入用開口端１０１ｂとをそれぞれ備え、両挿入用開口端１０１ａ、１０１ｂそれぞれの内側には、挿着されたＭＰＯ型コネクタプラグを係止するための、先端に鉤状の爪部を備えた左右方向へ撓曲自在なレバー片１０４を対向配置させてある。 That is, as a specific configuration of the adapter main body 100, as shown in FIGS. 16 to 20, both ends of the adapter main body 100 can be interconnected with the optical fiber tape core wires of the ferrule of the MPO type connector plug. One insertion opening end 101a and the other insertion opening end 101b are provided so that the optical axes are aligned with each other, and an MPO type is inserted inside both the insertion opening ends 101a and 101b. A lever piece 104 that is flexible in the left-right direction and has a hook-shaped claw at the tip for locking the connector plug is arranged so as to face each other.

また、アダプタ本体１００の上下側壁は、その各中間部に係止フランジ１０２が形成され、該係止フランジ１０２と一方の挿入用開口端１０１ａとの間に前記したパネル保持用のラッチレバー１０３が設けられている。前記係止フランジ１０２は、パネルのアダプタ取付孔の後面において当該パネルに係止されると同時に前記ラッチレバー１０３によってパネルのアダプタ取付孔の前面に係止保持される。 Further, on the upper and lower side walls of the adapter main body 100, a locking flange 102 is formed in each intermediate portion thereof, and the above-mentioned panel holding latch lever 103 is formed between the locking flange 102 and one of the insertion opening ends 101a. It is provided. The locking flange 102 is locked to the panel on the rear surface of the adapter mounting hole of the panel, and at the same time, is locked and held on the front surface of the adapter mounting hole of the panel by the latch lever 103.

さらに、前記両挿入用開口端１０１ａ、１０１ｂそれぞれの上下いずれかの内側壁中央には、ＭＰＯ型コネクタプラグ挿入時のガイドおよび安定保持のために、当該ＭＰＯ型コネクタプラグに設けられたキー突起（図示せず）を嵌合させるよう光軸方向に沿って直線溝条となったキー溝１０５が形成されている。 Further, at the center of either the upper or lower inner wall surface of each of the upper and lower opening ends 101a and 101b for both insertions, a key protrusion provided on the MPO type connector plug for guiding and stable holding when inserting the MPO type connector plug ( A key groove 105 formed as a straight groove along the optical axis direction is formed so as to fit (not shown).

ところで、このようなスナップイン方式によると、パネルのアダプタ取付孔とアダプタ本体１００との間に若干のクリアランスが生じるため、パネルを動かすとアダプタ本体１００が上下左右方向にガタが生じる。 By the way, according to such a snap-in method, a slight clearance is generated between the adapter mounting hole of the panel and the adapter main body 100, so that when the panel is moved, the adapter main body 100 is loosened in the vertical and horizontal directions.

このようなガタ付きを未然に防止するため、従来では、特許文献１に示すように、光コネクタ用のアダプタ本体に形成した取付孔に挿入し、該取付孔内側で折り込みあるいは圧入により固定可能となるよう形成した複数の爪脚部と、中央面が若干***してなる係止面とを有する係止バネを備えたガタ止め機構が提案されている。ここにおいて、前記係止バネは、その係止面がアダプタ本体の上側壁に向けて順次圧潰しながらパネルにおけるアダプタ取付部に嵌着保持するものとされている。 In order to prevent such rattling, conventionally, as shown in Patent Document 1, it can be inserted into a mounting hole formed in the adapter body for an optical connector and fixed by folding or press-fitting inside the mounting hole. A backlash prevention mechanism including a locking spring having a plurality of claw legs formed so as to be formed and a locking surface having a slightly raised central surface has been proposed. Here, the locking spring is supposed to be fitted and held to the adapter mounting portion on the panel while its locking surface is sequentially crushed toward the upper side wall of the adapter main body.

特開２００９－２３００３３号公報Japanese Unexamined Patent Publication No. 2009-230033

しかしながら、上記した特許文献１においては、上記係止バネはアダプタ本体とは別部材であるため、アダプタ本体の上側壁に係止バネ固定用の取付孔を形成するなどアダプタ本体自体の構造が複雑となり、製造コストも高くなる。しかも、光コネクタプラグの高密度実装における狭小スペース、例えば係止バネが付けられないスペースでは係止バネとしての本来の機能を十分に発揮することができない。 However, in Patent Document 1 described above, since the locking spring is a separate member from the adapter body, the structure of the adapter body itself is complicated, such as forming a mounting hole for fixing the locking spring on the upper side wall of the adapter body. Therefore, the manufacturing cost is also high. Moreover, in a narrow space in high-density mounting of the optical connector plug, for example, in a space where a locking spring cannot be attached, the original function as a locking spring cannot be fully exhibited.

そこで、本発明は、叙上のような従来存した諸事情に鑑み案出されたもので、アダプタ本体のガタ止めを別部材によらずに、当該アダプタ本体と一体構造によるものとすることで、簡易な構成で確実にガタ止め機能を発揮できる光コネクタ用アダプタのガタ止め機構を提供することを目的とする。 Therefore, the present invention has been devised in view of the above-mentioned conventional circumstances, and the backlash prevention of the adapter body is not based on a separate member, but is integrated with the adapter body. The purpose is to provide a backlash prevention mechanism for an optical connector adapter that can reliably exert a backlash prevention function with a simple configuration.

上述した課題を解決するために、本発明にあっては、アダプタ本体の外側面部がパネルのアダプタ取付孔の開口縁内側に押接するよう形成されたラッチレバーと、該ラッチレバーに対向すべく外側面部中央から外方に突設してなる係止フランジと、該係止フランジと前記ラッチレバーとの間における外側面部に形成された突起とを備え、前記アダプタ本体は、前記ラッチレバーを押圧しながら前記パネルのアダプタ取付孔に挿入され、前記係止フランジとラッチレバーとの間に当該アダプタ取付孔の開口縁部を挟んで固定すると共に、前記突起は少なくとも先端の一部が圧潰されて前記パネルのアダプタ取付孔の開口縁内側に圧接するよう形成し、一方前記パネルのアダプタ取付孔の内縁部には微小凹凸を形成してなることを特徴とする。 In order to solve the above-mentioned problems, in the present invention, a latch lever formed so that the outer surface portion of the adapter body is pressed against the inside of the opening edge of the adapter mounting hole of the panel is to face the latch lever. The adapter body has a locking flange protruding outward from the center of the outer side surface portion and a protrusion formed on the outer surface portion between the locking flange and the latch lever, and the adapter body presses the latch lever. While being inserted into the adapter mounting hole of the panel, the opening edge of the adapter mounting hole is sandwiched and fixed between the locking flange and the latch lever, and at least a part of the tip of the protrusion is crushed. It is characterized in that it is formed so as to be in pressure contact with the inside of the opening edge of the adapter mounting hole of the panel, while minute irregularities are formed on the inner edge portion of the adapter mounting hole of the panel .

前記ラッチレバーは、前記アダプタ本体の外側面部が前記パネルのアダプタ取付孔の開口縁内側に押接するよう斜め外方向に切り起こし折曲して形成されていることを特徴とする。 The latch lever is characterized in that the outer surface portion of the adapter body is formed by cutting and bending diagonally outward so as to press against the inside of the opening edge of the adapter mounting hole of the panel.

前記突起は、アダプタ本体の外側面部の上下両面または左右両面に、当該突起のサイズに応じて１個もしくは複数個が設けられてなることを特徴とする。 The protrusions are characterized in that one or a plurality of the protrusions are provided on both the upper and lower sides or the left and right sides of the outer surface portion of the adapter body depending on the size of the protrusions.

前記突起は、平面視で略丸形、多角形、楕円形のいずれかの形状を呈してなることを特徴とする。 The protrusion is characterized in that it exhibits a substantially round shape, a polygonal shape, or an elliptical shape in a plan view.

前記突起は、前記パネルのアダプタ取付孔の開口縁に対して僅かに大きいかもしくは略同じ高さを有してなることを特徴とする。 The protrusion is characterized in that it is slightly larger or has approximately the same height with respect to the opening edge of the adapter mounting hole of the panel.

本発明によれば、アダプタ本体のガタ止めを別部材によらずに、当該アダプタ本体と一体構造によるものとすることで、簡易な構成で確実にガタ止め機能を発揮できる光コネクタ用アダプタのガタ止め機構を安価に提供することができる。 According to the present invention, the backlash of the adapter main body is not based on a separate member, but is integrated with the adapter main body, so that the backlash of the adapter for the optical connector can be reliably exerted with a simple configuration. The stopping mechanism can be provided at low cost.

すなわち、本発明は、アダプタ本体の外側面部がパネルのアダプタ取付孔の開口縁内側に押接するよう形成されたラッチレバーと、該ラッチレバーに対向すべく外側面部中央から外方に突設してなる係止フランジと、該係止フランジと前記ラッチレバーとの間における外側面部に形成された突起とを備え、前記アダプタ本体は、前記ラッチレバーを押圧しながら前記パネルのアダプタ取付孔に挿入され、前記係止フランジとラッチレバーとの間に当該アダプタ取付孔の開口縁部を挟んで固定すると共に、前記突起は少なくとも先端の一部が圧潰されて前記パネルのアダプタ取付孔の開口縁内側に圧接するよう形成し、一方前記パネルのアダプタ取付孔の内縁部には微小凹凸を形成してなるので、前記パネルのアダプタ取付孔にアダプタ本体を挿入した際に、当該アダプタ取付孔の開口縁内側とアダプタ本体の側面との間に発生した隙間（クリアランス）に起因するガタの発生を前記突起及び前記微小凹凸によって効果的に防止することができる。要するに、前記突起の他に、パネルのアダプタ取付孔の微小凹凸を設けることによって、よりいっそうのフィット効果が期待できるものである。 That is, in the present invention, a latch lever is formed so that the outer surface portion of the adapter body is pressed against the inside of the opening edge of the adapter mounting hole of the panel, and the latch lever is projected outward from the center of the outer surface portion so as to face the latch lever. The adapter body is inserted into the adapter mounting hole of the panel while pressing the latch lever. The opening edge of the adapter mounting hole is sandwiched and fixed between the locking flange and the latch lever, and at least a part of the tip of the protrusion is crushed inside the opening edge of the adapter mounting hole of the panel. It is formed so as to be in pressure contact, while the inner edge of the adapter mounting hole of the panel is formed with minute irregularities. Therefore, when the adapter body is inserted into the adapter mounting hole of the panel, the inside of the opening edge of the adapter mounting hole is formed. The protrusions and the minute irregularities can effectively prevent the occurrence of play due to the gap (clearance) generated between the adapter body and the side surface of the adapter body. In short, a further fitting effect can be expected by providing minute irregularities in the adapter mounting holes of the panel in addition to the protrusions.

前記ラッチレバーは、前記アダプタ本体の外側面部が前記パネルのアダプタ取付孔の開口縁内側に押接するよう斜め外方向に切り起こし折曲して形成されているので、前記アダプタ本体と同一部材で一体構造となっている分、堅牢性に優れていると共に、ガタの発生防止に一層効果的である。 Since the latch lever is formed by cutting and bending diagonally outward so that the outer surface portion of the adapter body is pressed against the inside of the opening edge of the adapter mounting hole of the panel, the latch lever is integrated with the same member as the adapter body. Due to its structure, it has excellent robustness and is more effective in preventing backlash.

前記突起は、アダプタ本体の外側面部の上下両面または左右両面に、当該突起のサイズに応じて１個もしくは複数個が設けられてなるので、アダプタ取付孔の開口縁内側とアダプタ本体の外側面との間に発生した隙間に起因するガタの発生を、前記突起の個数とサイズとのバランスによって挿入時の嵌合摩擦抵抗を極力抑えつつ効果的に防止することができる。 Since one or more of the protrusions are provided on both the upper and lower sides or the left and right sides of the outer surface portion of the adapter body depending on the size of the protrusions, the inside of the opening edge of the adapter mounting hole and the outer surface of the adapter body. By balancing the number and size of the protrusions, it is possible to effectively prevent the occurrence of backlash caused by the gaps generated between the two while suppressing the fitting frictional resistance at the time of insertion as much as possible.

前記突起は、平面視で略丸形、多角形、楕円形のいずれかの形状を呈してなるので、接触の可能性がある箇所については潰れ易い形状となり、これによってガタの発生を確実に防止することができる。 Since the protrusions have a substantially round shape, a polygonal shape, or an elliptical shape in a plan view, the protrusions have a shape that is easily crushed at a place where there is a possibility of contact, thereby reliably preventing the occurrence of backlash. can do.

前記突起は、前記パネルのアダプタ取付孔の開口縁に対して僅かに大きいかもしくは略同じ高さを有してなるので、パネルをスライドさせてアダプタ本体側のラッチレバーを超えて嵌め込む際に、前記突起がアダプタ取付孔の開口縁部で擦られることで潰れて、前記パネルの取付孔に合わせた形状に確実にフィットさせることができる。 The protrusions are slightly larger or have approximately the same height as the opening edge of the adapter mounting hole of the panel, so that when the panel is slid and fitted beyond the latch lever on the adapter body side. The protrusion is crushed by being rubbed by the opening edge of the adapter mounting hole, and can be reliably fitted to the shape of the panel mounting hole.

以下、図面を参照して本発明に係る光コネクタ用アダプタのガタ止め機構の実施の一形態をＭＰＯ用のアダプタ本体１に適用した場合について詳細に説明する。尚、アダプタ本体１は、単心あるいは多連でも良く、またアダプタ本体１の種類もＭＰＯアダプタだけでなく、例えばＳＣ、ＬＣ、ＭＵ等の各他種のアダプタにも本発明が適用可能であることは勿論である。 Hereinafter, a case where an embodiment of the backlash prevention mechanism of the optical connector adapter according to the present invention is applied to the adapter main body 1 for MPO will be described in detail with reference to the drawings. The adapter body 1 may be single-core or multiple, and the type of the adapter body 1 is not limited to the MPO adapter, but the present invention can be applied to other types of adapters such as SC, LC, and MU. Of course.

本発明に係るアダプタ本体１は、図１乃至図５に示すように、例えば合成樹脂の成型品によって角筒状に形成されており、不図示のＭＰＯ型コネクタプラグのフェルールの光ファイバテープ心線を相互接続できるように、当該アダプタ本体１の両端に、光学軸が一致するようにして、一方の挿入用開口端１ａと、他方の挿入用開口端１ｂとをそれぞれ備え、両挿入用開口端１ａ、１ｂそれぞれの左右内壁面には、挿着されたＭＰＯ型コネクタプラグ（図示せず）を係止するための、先端に鉤状の爪部を備えた左右方向へ撓曲自在なレバー片４を対向配置させてある。 As shown in FIGS. 1 to 5, the adapter body 1 according to the present invention is formed in a square tube shape, for example, by a molded product of synthetic resin, and is an optical fiber tape core wire of a ferrule of an MPO type connector plug (not shown). The adapter body 1 is provided with one insertion opening end 1a and the other insertion opening end 1b so that the optical axes coincide with each other so that the adapter main body 1 can be interconnected. A lever piece that is flexible in the left-right direction and has a hook-shaped claw at the tip for locking the inserted MPO-type connector plug (not shown) on the left and right inner wall surfaces of 1a and 1b. 4 are arranged facing each other.

また、前記アダプタ本体１の上下外側面は、その各中間部から外方に突設してなる矩形状の係止フランジ２が形成され、該係止フランジ２と一方の挿入用開口端１ａとの間には、アダプタ本体１の外側面部がパネルＰのアダプタ取付孔Ｑの開口縁内側に押接するよう左右一対のパネル保持用のラッチレバー３が形成されている。前記係止フランジ２は、前記パネルＰのアダプタ取付孔Ｑ（図１２乃至図１５参照）の後面において当該パネルＰに係止されると同時に、前記ラッチレバー３によってパネルＰのアダプタ取付孔Ｑの前面に係止保持される。 Further, on the upper and lower outer surfaces of the adapter main body 1, a rectangular locking flange 2 is formed so as to project outward from each intermediate portion thereof, and the locking flange 2 and one of the insertion opening ends 1a are formed. A pair of left and right panel holding latch levers 3 are formed between the adapter bodies 1 so that the outer surface portion of the adapter body 1 presses against the inside of the opening edge of the adapter mounting hole Q of the panel P. The locking flange 2 is locked to the panel P on the rear surface of the adapter mounting hole Q (see FIGS. 12 to 15) of the panel P, and at the same time, the latch lever 3 of the adapter mounting hole Q of the panel P. Locked and held on the front.

前記実施形態では、パネル保持用のラッチレバー３は、前記アダプタ本体１の外側面部の上下左右の両面を斜め外方向に各々切り起こし折曲することで当該アダプタ本体１と一体に形成されているが、本発明はこのような構造に限定されるものではなく、例えば必要な個数（本例では４個）の前記ラッチレバー３を別個に製作し、これらを前記アダプタ本体１の外側面部の当該部位に溶着、接着などの固定手段を使って一体に形成することもできる。 In the embodiment, the panel holding latch lever 3 is integrally formed with the adapter main body 1 by cutting and bending both the upper, lower, left and right sides of the outer surface portion of the adapter main body 1 in the diagonally outward direction. However, the present invention is not limited to such a structure. For example, a required number (4 in this example) of the latch levers 3 are separately manufactured, and these are separately manufactured and used on the outer surface portion of the adapter body 1. It can also be integrally formed on the site by using fixing means such as welding and adhesion.

また、前記した左右一対のラッチレバー３と、前記係止フランジ２との間における上下外側面部、すなわち、パネルＰのアダプタ取付孔Ｑの開口縁内側が係合するアダプタ本体１の上下側外壁面には、例えば平面視略丸形を呈する突起６を備えている。この突起６は、前記アダプタ本体１の上下両面に１個ずつ、あるいは２個ずつ（図１乃至図４参照）等複数個設けることもできる。この場合、これら突起６は、前記パネルＰのアダプタ取付孔Ｑの開口縁に対して僅かに大きいかもしくは略同じ高さを有しており、当該パネルＰをスライドさせてアダプタ本体１側のラッチレバー３を超えて嵌め込んだ際に、前記突起６がアダプタ取付孔Ｑの開口縁部で擦られることで潰れて、前記パネルＰのアダプタ取付孔Ｑに略合わせた形状にフィットさせるものとしてある。尚、前記パネルＰのアダプタ取付孔Ｑの内縁部がフラットではなく微小凹凸を設けることにより、よりいっそうのフィット効果が期待できるものである。 Further, the upper and lower outer wall surfaces of the adapter main body 1 with which the upper and lower outer surface portions between the pair of left and right latch levers 3 and the locking flange 2, that is, the inside of the opening edge of the adapter mounting hole Q of the panel P are engaged. Is provided with, for example, a protrusion 6 having a substantially round shape in a plan view. A plurality of the protrusions 6 may be provided on both the upper and lower surfaces of the adapter body 1 one by one or two by two (see FIGS. 1 to 4). In this case, these protrusions 6 are slightly larger than or have substantially the same height as the opening edge of the adapter mounting hole Q of the panel P, and the panel P is slid to be latched on the adapter body 1 side. When the lever 3 is fitted over the lever 3, the protrusion 6 is crushed by being rubbed by the opening edge of the adapter mounting hole Q, so that the protrusion 6 fits into a shape substantially matched with the adapter mounting hole Q of the panel P. .. It should be noted that the inner edge of the adapter mounting hole Q of the panel P is not flat but has minute irregularities , so that a further fitting effect can be expected.

而して、前記アダプタ本体１が前記ラッチレバー３を押圧しながらアダプタ取付孔Ｑ（アダプタ本体１に対しパネルＰが大きな抵抗なく挿入できる大きさ）に挿入された際には、前記係止フランジ２とラッチレバー３との間にアダプタ取付孔Ｑの開口縁部を挟んで固定すると同時に、前記突起６は少なくとも先端の一部が圧潰されてアダプタ取付孔Ｑの開口縁内側に圧接する。このようにパネルＰの嵌合時にアダプタ取付孔Ｑのサイズに合わせて潰れることで両部材の接触面の摩擦抵抗が増え前記アダプタ本体１の上下左右方向のガタ付を防止する構造としている。 Therefore, when the adapter body 1 is inserted into the adapter mounting hole Q (the size at which the panel P can be inserted into the adapter body 1 without a large resistance) while pressing the latch lever 3, the locking flange is used. At the same time that the opening edge portion of the adapter mounting hole Q is sandwiched and fixed between 2 and the latch lever 3, at least a part of the tip of the protrusion 6 is crushed and pressed against the inside of the opening edge of the adapter mounting hole Q. In this way, when the panel P is fitted, it is crushed according to the size of the adapter mounting hole Q, so that the frictional resistance of the contact surfaces of both members is increased and the adapter body 1 is prevented from rattling in the vertical and horizontal directions.

さらに、前記両挿入用開口端１ａ、１ｂそれぞれの上下いずれかの側壁中央には、ＭＰＯ型コネクタプラグ挿入時のガイドおよび安定保持のために、当該ＭＰＯ型コネクタプラグに設けられたキー突起（図示せず）を嵌合させるよう光軸方向に沿って直線溝条となったキー溝５が形成されている。 Further, at the center of either the upper or lower side wall of each of the upper and lower side walls of the opening ends 1a and 1b for both insertions, a key protrusion provided on the MPO type connector plug for guiding and stable holding when inserting the MPO type connector plug (FIG. A keyway 5 formed as a straight groove along the optical axis direction is formed so as to fit (not shown).

尚、前記突起６は、アダプタ本体１の左右外側面部に、当該突起６のサイズに応じて１個もしくは複数個ずつ設けても良い。また、前記突起６は、図示のように平面視略丸形が好適であるが、必ずしもこれに限られるものではなく、例えば平面視で略多角形、楕円形のいずれかの形状を呈していても良い。 The protrusions 6 may be provided on the left and right outer surface portions of the adapter main body 1 one by one or a plurality of protrusions 6 depending on the size of the protrusions 6. Further, the protrusion 6 is preferably a substantially round shape in a plan view as shown in the drawing, but is not necessarily limited to this, and has, for example, a shape of either a substantially polygonal shape or an elliptical shape in a plan view. Is also good.

次に、図６乃至図９に基づき、アダプタ本体１の他例について説明する。
本例では、本件出願人によって先に出願された特開２０１１－１３３６１１号公報に開示されている略コ字枠状のガタ止め具１１（前記公開公報では「１」）が、ＳＣ型コネクタプラグ挿入用のアダプタ本体１の上壁面から左右両側面にかけて略コ字状の扁平な溝となって凹設された係合部１２に装着して使用される。 Next, another example of the adapter main body 1 will be described with reference to FIGS. 6 to 9.
In this example, the substantially U-shaped frame-shaped backlash stopper 11 (“1” in the above-mentioned publication) disclosed in Japanese Patent Application Laid-Open No. 2011-133611 filed earlier by the applicant is an SC type connector plug. The adapter body 1 for insertion is used by being attached to the recessed engaging portion 12 as a substantially U-shaped flat groove from the upper wall surface to the left and right side surfaces.

尚、前記係合部１２は、前記アダプタ本体１の左右外側面の略中央に互いに外向きとなって突設された係止フランジ１３を介して前後一対となって形成されており、パネルＰのアダプタ取付孔Ｑへの挿入方向に対応して、これら係合部１２のうちいずれか一方にガタ止め具１１が装着される。 The engaging portions 12 are formed in pairs in the front-rear direction via locking flanges 13 projecting outward from each other at substantially the center of the left and right outer surfaces of the adapter main body 1.
