Description
本発明は防水構造を備える電源接続装置に関し、より詳細には、電源を接続する接続箇所にゴム材料を有し、当該接続箇所の密封性を複数の縦棒及び横棒構造により強化することで、水気の浸み込みを防止して意図しないリスクを低下させるとの目的を達成するものである。 The present invention relates to a power supply connection device having a waterproof structure, and more specifically, by having a rubber material at a connection point for connecting a power supply and enhancing the sealing property of the connection point by a plurality of vertical bar and horizontal bar structures. , It achieves the purpose of preventing infiltration of water and reducing unintended risks.
人類社会に電力が普及して以降、我々の生活には各種機能の電気機器が導入されるようになった。電気機器には、電気エネルギーや電気信号の伝送、或いは交流及び直流の変圧や整流といった機能を有する電源接続装置が取り付けられている。例えば、現在市場で一般的なノートパソコンの電源接続装置には整流機能が遍く備わっている。また、携帯型スマート機器の電源接続装置は、信号及び電気エネルギーの伝送、整流機能等を兼ね備えている。 Since the spread of electric power in human society, electric appliances with various functions have been introduced into our lives. A power supply connecting device having a function of transmitting electric energy or electric signals, or transforming or rectifying AC and DC is attached to the electric equipment. For example, the power supply connection device of a notebook computer, which is currently popular in the market, has a rectifying function. In addition, the power supply connection device of the portable smart device has a function of transmitting signals and electric energy, a rectification function, and the like.
図１を参照して、従来技術では、一般的な電源接続装置（１００）の構成として、通常はプリント回路（１０１１）又は電子部品を内部に含む電源モジュール（１０１）を有しており、電気エネルギーや電気信号を伝送する接続ケーブル（１０３）が、電源モジュール（１０１）の外部に設けられた接続ポート（１０１３）における対応する各種オス、メスコネクタを介して接続される。しかし、上述した従来の電源接続装置（１００）の構成では、電源モジュール（１０１）の外部に設けられた接続ポート（１０１３）に防水又は防塵構造が備わっておらず、往々にして水気や浮遊微粒子が接続ポート（１０１３）の電極に浸み込んだり蓄積したりしやすい。そのため、装置が次第に老朽化するに伴って電極が腐食し、故障や短絡が生じる結果、装置全体の電圧が瞬間的に上昇する。これにより、電気エネルギーを供給する電気機器が損傷することで寿命が短縮し、ひいては火災や漏電が招来される。 With reference to FIG. 1, in the related art, as a configuration of a general power supply connection device (100), a power supply module (101) that normally includes a printed circuit (1011) or an electronic component therein is provided. A connection cable (103) for transmitting energy and electric signals is connected via corresponding male and female connectors in a connection port (1013) provided outside the power supply module (101). However, in the above-described configuration of the conventional power supply connection device (100), the connection port (1013) provided outside the power supply module (101) is not provided with a waterproof or dustproof structure, and water and airborne particles are often present. Easily penetrates into and accumulates in the electrode of the connection port (1013). Therefore, as the device gradually deteriorates, the electrodes corrode, causing a failure or a short circuit. As a result, the voltage of the entire device instantaneously rises. As a result, the electrical equipment that supplies the electrical energy is damaged, shortening the life of the electrical equipment and eventually leading to a fire or an electric leakage.
そこで、現在、市場には防水構造を備える電源接続装置を打ち出すメーカーも現れており、例えば、特許文献１は、防水構造を備える電源コネクタを開示している。当該電源コネクタのコネクタハウジングの構造は、接続ポートのインターフェース表面に装設されるゴムワッシャを含むとともに、電線をコネクタの内部と外部に挿設可能とすべくハウジングの先端に設けられる複数の凹溝を備える。接続の過程では、一定レベルの防水性能を備えるよう、接続ポートと接続ケーブルを当該ゴムワッシャの変形によって互いにしっかりと噛合させる。しかし、現在のところ、このような防水構造には依然として改良の余地が残されている。まず、ゴムワッシャについて、現在市販されている製品の多くは、接続ポートにおけるインターフェースの平面のうち電極付近の位置にのみゴムワッシャが敷設され、接続ポートにおけるインターフェースの表面全体に完全に敷設されるわけではない。そのため、依然として水気が接続ポートと接続ケーブルとの隙間に浸み込む恐れがあり、全面的な防水機能は達し得ない。また、接続ポートと接続ケーブルの表面構造は、接続過程で内部の残留空気を均等に外部へ押し出す構成とはなっていないか、そのような構成のものは少数である。そのため、接続ポートと接続ケーブルとの隙間に少量の空気が存在したままとなって、電源接続装置全体の密封性が低下する。 Therefore, at present, some manufacturers have launched a power supply connection device having a waterproof structure, and for example, Patent Document 1 discloses a power supply connector having a waterproof structure. The structure of the connector housing of the power supply connector includes a rubber washer mounted on the interface surface of the connection port, and a plurality of recessed grooves provided at the tip of the housing to allow the electric wire to be inserted inside and outside the connector. Equipped with. In the process of connection, the connection port and the connection cable are firmly meshed with each other by the deformation of the rubber washer so as to have a certain level of waterproof performance. However, at present, such a waterproof structure still has room for improvement. First, with regard to rubber washers, most of the products currently on the market have rubber washers laid only near the electrodes on the plane of the interface at the connection port and completely laid over the entire surface of the interface at the connection port. is not. Therefore, water may still permeate into the gap between the connection port and the connection cable, and the overall waterproof function cannot be achieved. Further, the surface structure of the connection port and the connection cable is not configured to evenly push out the residual air inside during the connection process to the outside, or there are few such configurations. Therefore, a small amount of air remains in the gap between the connection port and the connection cable, and the sealing performance of the entire power supply connection device deteriorates.
そこで、上記より、現在の市場では、密封性を改善して電源接続装置への水気の浸み込みを阻止するとの目的を達成すべく、電源接続装置の防水構造を改良することが依然として求められている。 Therefore, from the above, in the current market, it is still required to improve the waterproof structure of the power supply connection device in order to achieve the purpose of improving the sealing property and preventing the infiltration of water into the power supply connection device. ing.
上記の従来技術における欠点に鑑みて、本発明は、接続ポートと第１ゴムワッシャが設けられ、接続ポートが第１縦棒と第２縦棒をそれぞれ備え、且つ、当該第１縦棒の長さが当該第２縦棒よりも大きい電源モジュールと、接続ケーブルハウジングを有する接続ケーブルと、接続ケーブルハウジングの先端に設けられるコネクタと、を含み、接続ケーブルハウジングの先端表面に第２ゴムワッシャが設けられており、電源モジュールと接続ケーブルが電気的に連接する際に、第２ゴムワッシャと第１ゴムワッシャが互いに押圧及び噛合することで電源接続装置が固定され、前記の第１縦棒と第２縦棒はコネクタの設置方向に対し垂直であり、縦方向の押圧によって空気を電源接続装置から排出し、接続の密封性を向上させる防水構造を備える電源接続装置を提供する。 In view of the above-mentioned drawbacks of the prior art, the present invention provides a connection port and a first rubber washer, the connection port includes a first vertical bar and a second vertical bar, respectively, and the length of the first vertical bar. A power supply module having a size larger than the second vertical bar, a connection cable having a connection cable housing, and a connector provided at a tip of the connection cable housing, and a second rubber washer provided on a tip surface of the connection cable housing. When the power supply module and the connection cable are electrically connected to each other, the second rubber washer and the first rubber washer press and mesh with each other to fix the power supply connection device, and the first vertical bar and the first vertical bar are connected to each other. The two vertical bars are perpendicular to the installation direction of the connector and provide a power supply connection device having a waterproof structure that discharges air from the power supply connection device by pressing in the vertical direction and improves the sealing property of the connection.
本発明の内容によれば、前記コネクタは第１横棒と第２横棒を含み、コネクタと電源モジュールの連接過程において、前記第１縦棒及び第２縦棒とともに横方向及び縦方向の押圧力経路をそれぞれ形成する。これにより、コネクタと接続ポートとの隙間における空気の緩やかな排出を促すことで、接続の密封性を更に向上させる。 According to the content of the present invention, the connector includes a first horizontal bar and a second horizontal bar, and in the connecting process of the connector and the power supply module, the first vertical bar and the second vertical bar are pushed together in the horizontal and vertical directions. Each pressure path is formed. This promotes the gentle discharge of air in the gap between the connector and the connection port, thereby further improving the sealing property of the connection.
上記について、接続ケーブルのコネクタを正面から見ると、複数の第１横棒と第２横棒の配列により「∞」状構造が形成される。当該「∞」状構造は、電源モジュールとの連接過程における受力面積が従来の「Ｏ」状構造よりも大きくなるため、コネクタの左右両端における圧力が均等となる。よって、密封性が改善されるとともに、電源接続装置において、コネクタの左右両端の圧力が一致しないために、コネクタの高圧側の一端は密封性が向上するが、低圧側の一端には隙間が生じ、環境中の空気や水気、浮遊微粒子が電源接続装置の内部に進入して正常な運転に支障をきたす恐れがなくなる。 With respect to the above, when the connector of the connection cable is viewed from the front, the “∞”-like structure is formed by the arrangement of the plurality of first horizontal bars and the second horizontal bars. The “∞”-shaped structure has a larger force-receiving area in the process of connecting with the power supply module than the conventional “O”-shaped structure, so that the pressures at the left and right ends of the connector are equalized. Therefore, the sealability is improved, and in the power supply connection device, since the pressures at the left and right ends of the connector do not match, the sealability is improved at one end on the high voltage side of the connector, but there is a gap at the end on the low voltage side. Therefore, there is no possibility that air, water, and airborne particles in the environment enter the inside of the power supply connection device and hinder normal operation.
また、接続ケーブルハウジングの後端には後端ゴムカバーが設けられており、接続ケーブルと接続ケーブルハウジングとの隙間を封止している。これにより、接続ケーブルハウジングの外部と内部が隔離されるため、外部環境における空気や水気、浮遊微粒子が接続ケーブルハウジングの内部に進入するとの事態が阻止される。 Further, a rear end rubber cover is provided at the rear end of the connection cable housing to seal the gap between the connection cable and the connection cable housing. As a result, the outside and the inside of the connection cable housing are separated from each other, so that it is possible to prevent air, water, and suspended particles in the external environment from entering the inside of the connection cable housing.
本発明の内容によれば、第２ゴムワッシャ及び第１ゴムワッシャには、ポリウレタン（Ｐｏｌｙｕｒｅｔｈａｎｅ，ＰＵ）、ブチルゴム（Ｂｕｔｙｌ Ｒｕｂｂｅｒ，ＩＩＲ）、ハイパロンゴム（Ｈｙｐａｌｏｎ Ｐｏｌｙｅｔｈｌｅｎｅ Ｒｕｂｂｅｒ，ＣＳＭ）、天然ゴム（Ｎａｔｕｒａｌ Ｒｕｂｂｅｒ，ＮＲ）、ポリアクリル酸ゴム（Ｐｏｌｙａｃｒｙｌａｔｅ Ｒｕｂｂｅｒ，ＡＣＭ）、ネオプレンゴム（Ｎｅｏｐｒｅｎｅ Ｒｕｂｂｅｒ，ＣＲ）等を使用してもよいし、これら材料の組み合わせとしてもよいが、上記に限らない。 According to the content of the present invention, the second rubber washer and the first rubber washer include polyurethane (Polyurethan, PU), butyl rubber (Butyl Rubber, IIR), hypalon rubber (Hypalon Polyethylene rubber, CSM), natural rubber (Natural Rubber). , NR), polyacrylate rubber (Polymerized Rubber, ACM), neoprene rubber (Neoprene Rubber, CR), or the like, or a combination of these materials, but not limited to the above.

本発明は、まずは、ゴムワッシャのような部分について、従来の電源接続装置の防水構造を改良することを目的とする。本発明のゴムワッシャは、インサート成形方式によって、接続ポート及びコネクタにおけるインターフェースの平面に、電極付近の位置も含めて完全に敷設されるため、水気や浮遊微粒子が接続ケーブルハウジングの内部に進入する恐れが除去される。また、電源モジュールと接続ケーブルの連接過程において、内部の残留空気をできる限り均等に外部へ押し出す構成とすることで、コネクタ両端の圧力が均一化するため、低圧の隙間から水気が浸み込む恐れが低下する。なお、詳細な構造及び実施形態については以下で詳述する。最後に、本発明では、前記複数の第１縦棒、第２縦棒、第１横棒、第２横棒について、応用上の必要性に基づいて適切な数量を選択可能である。また、これらはそれぞれ「縦棒」及び「横棒」と総称される。なお、これらもまた同様に説明のためのものにすぎず、本発明の権利範囲を制限するものではない。 An object of the present invention is to improve a waterproof structure of a conventional power supply connecting device for a portion such as a rubber washer. Since the rubber washer of the present invention is completely laid by the insert molding method on the plane of the interface of the connection port and the connector, including the position near the electrode, water and airborne particles may enter the inside of the connection cable housing. Are removed. In addition, in the process of connecting the power supply module and the connection cable, the residual air inside is pushed out to the outside as evenly as possible, so that the pressure at both ends of the connector is equalized, so that water vapor may infiltrate from the low-pressure gap. Is reduced. The detailed structure and embodiment will be described in detail below. Finally, in the present invention, an appropriate quantity can be selected for the plurality of first vertical bars, second vertical bars, first horizontal bars, and second horizontal bars based on application needs. In addition, these are collectively referred to as "vertical bar" and "horizontal bar", respectively. It should be noted that these are also just for explanation, and do not limit the scope of rights of the present invention.
図２及び図３を参照して、本発明は、防水構造を備える電源接続装置（２００）を提供する。当該装置は、接続ポート（２０１３）と第１ゴムワッシャ（２０１１）が設けられ、接続ポート（２０１３）が第１縦棒（２０１５）と第２縦棒（２０１７）をそれぞれ備え、且つ、第１縦棒（２０１５）の長さが第２縦棒（２０１７）よりも大きい電源モジュール（２０１）と、接続ケーブルハウジング（２０３３）を有する接続ケーブル（２０３）を含む。また、コネクタ（２０３１）が接続ケーブルハウジング（２０３３）の先端に設けられ、接続ケーブルハウジング（２０３３）の先端表面に第２ゴムワッシャ（２０３７）が設けられている。電源モジュール（２０１）と接続ケーブル（２０３）が電気的に連接する際には、第２ゴムワッシャ（２０３７）と第１ゴムワッシャ（２０１１）が互いに押圧及び噛合することで電源接続装置が固定される。前記第１縦棒（２０１５）と第２縦棒（２０１７）はコネクタ（２０３１）の設置方向に対し垂直であり、縦方向の押圧によって空気を電源接続装置から排出し、接続の密封性を向上させる。 2 and 3, the present invention provides a power supply connection device (200) having a waterproof structure. The device is provided with a connection port (2013) and a first rubber washer (2011), the connection port (2013) includes a first vertical bar (2015) and a second vertical bar (2017), respectively. It includes a power supply module (201) in which the length of the vertical bar (2015) is longer than the second vertical bar (2017), and a connection cable (203) having a connection cable housing (2033). Further, the connector (2031) is provided at the tip of the connection cable housing (2033), and the second rubber washer (2037) is provided on the tip surface of the connection cable housing (2033). When the power supply module (201) and the connection cable (203) are electrically connected, the second rubber washer (2037) and the first rubber washer (2011) press and mesh with each other to fix the power supply connection device. It The first vertical bar (2015) and the second vertical bar (2017) are perpendicular to the installation direction of the connector (2031), and the air is discharged from the power supply connection device by the vertical pressing to improve the sealing property of the connection. Let
前記接続ケーブルハウジング（２０３３）の外形は箱型構造をなしており、先端と基端に接続ケーブル（２０３）の配線材料を挿設するための貫通孔が設けられている。先端の貫通孔には横棒が組み合わされて「∞」状構造をなしている。また、後端は、接続ケーブル（２０３）の配線材料を徐々に収束することで接続ケーブル（２０３）に対する接続ケーブルハウジング（２０３３）の密封性が向上するよう、２つ又は複数の半径の異なる円柱形状が積層されてなる。 The outer shape of the connection cable housing (2033) has a box-shaped structure, and a through hole for inserting the wiring material of the connection cable (203) is provided at the front end and the base end. A horizontal bar is combined with the through hole at the tip to form an "∞"-like structure. In addition, the rear end has two or more cylinders with different radii so that the wiring material of the connection cable (203) is gradually converged to improve the sealing property of the connection cable housing (2033) with respect to the connection cable (203). The shapes are laminated.
図３を参照して、本発明の一実施例において、前記第１縦棒（２０１５）は第２縦棒（２０１７）の左側に位置している。当該第１縦棒（２０１５）の長さを第２縦棒（２０１７）よりも大きくしているのは、コネクタ（２０３１）を電源モジュール（２０１）に挿入する際に、左側に位置する第１縦棒（２０１５）が第２縦棒（２０１７）よりも大きな押圧力を付与できるようにするためである。これにより、第１ゴムワッシャと第２ゴムワッシャが互いに噛合及び押圧される過程で残留空気が右側へと押し出され、電源接続装置（２００）の外部に排出されるため、電源接続装置（２００）の密封性が向上する。よって、環境中の水気や浮遊微粒子の電源接続装置（２００）に対する浸み込みを防止するとの目的が達成される。 Referring to FIG. 3, in one embodiment of the present invention, the first vertical bar (2015) is located on the left side of the second vertical bar (2017). The length of the first vertical bar (2015) is larger than that of the second vertical bar (2017) because the first vertical bar (2015) is located on the left side when the connector (2031) is inserted into the power supply module (201). This is because the vertical bar (2015) can apply a larger pressing force than the second vertical bar (2017). As a result, residual air is pushed out to the right in the process of the first rubber washer and the second rubber washer being meshed with each other and pressed, and is discharged to the outside of the power supply connecting device (200). The sealing property of is improved. Therefore, the purpose of preventing water and airborne particles in the environment from seeping into the power supply connection device (200) is achieved.
上述した本発明の好ましい実施例では、コネクタ（２０３１）の中央の長さがコネクタ（２０３１）の周縁よりも長くなるよう、第２横棒（２０３９）の長さを第１横棒（２０３８）よりも長くしている。且つ、横棒同士は互いに平行である。本発明の観点において、このような構造は、コネクタ（２０３１）が電源モジュール（２０１）に挿入される際に、第２横棒（２０３９）を中央に位置させることで、周縁の第１横棒（２０３８）よりも残留空気に対する押圧力を大きくし、連接過程で空気を確実に電源接続装置（２００）から排出することを目的としている。このように、上記の縦棒と横棒によって二方向の押圧力経路をそれぞれ形成し、コネクタ（２０３１）と電源モジュール（２０１）との隙間の空気が確実に排出されるよう促すことで、接続の密封性を更に向上させている。 In the preferred embodiment of the present invention described above, the length of the second horizontal bar (2039) is set so that the central length of the connector (2031) is longer than the peripheral edge of the connector (2031). Have been longer than. Moreover, the horizontal bars are parallel to each other. In view of the present invention, such a structure allows the second horizontal bar (2039) to be positioned at the center when the connector (2031) is inserted into the power supply module (201), so that the first horizontal bar at the peripheral edge is positioned. The purpose is to make the pressing force against the residual air larger than that of (2038) and to reliably discharge the air from the power supply connection device (200) in the connecting process. As described above, the vertical bars and the horizontal bars form two-direction pressing force paths respectively, and promptly ensure that the air in the gap between the connector (2031) and the power supply module (201) is exhausted, thereby connecting. The sealing performance of is further improved.
図５を参照して、接続ケーブル（２０３）のコネクタ（２０３１）を正面から見ると、複数の第１横棒（２０３８）と第２横棒（２０３９）が配列されて「∞」状構造をなしている。これにより、接続ポート（２０１３）におけるコネクタ（２０３１）の受力面積をできる限り拡大し、コネクタ（２０３１）の左右両端における圧力が均等となるようにしている。また、第２ゴムワッシャ（２０３７）は、コネクタ（２０３１）の内側及びこれと平行な表面に全体的に敷設されている。また、本発明の観点では、伝送する電気エネルギーや電気信号が大量となる場合に（例えば、高速充電を強調する大電流充電器や、ハイスループットのデータストリームを強調する伝送器の場合）、電源接続装置（２００）がコネクタ（２０３１）又は接続ポート（２０１３）に複数のピン（ｍｕｌｔｉｐｌｅ−ｐｉｎ）を要するときは、応用上の必要性に応じて相応数の縦棒及び横棒を補充すればよい。これにより、電源接続装置（２００）に複数の「∞」状構造を有するコネクタ（２０３１）を形成し、電源接続装置（２００）の接続ポート（２０１３）の圧力を同一に維持することで、密封性を効果的に向上させられる。本発明で提供する防水構造では、比較的経済的なコストでＩＰＸ４以上の要求を満たすことができる。即ち、国際保護等級（Ｉｎｔｅｒｎａｔｉｏｎａｌ Ｐｒｏｔｅｃｔｉｏｎ Ｍａｒｋｉｎｇ，ＩＰ）の認証基準に基づき、本発明が提供する電源接続装置（２００）は、８０〜１００ｋＰａの水圧、１０Ｌ／ｍｉｎの水流量、連続５分間の散水を受けても損傷することがない。また、応用上の必要性に応じて防水基準をＩＰＸ８のレベルまで向上させられる。本発明の実施例において、密封性は低真空（Ｒｏｕｇｈ Ｖａｃｕｕｍ）から中真空（Ｍｅｄｉｕｍ Ｖａｃｕｕｍ）の範囲、即ち１０〜７５０Ｔｏｒｒの間となる。 Referring to FIG. 5, when the connector (2031) of the connection cable (203) is viewed from the front, a plurality of first horizontal bars (2038) and second horizontal bars (2039) are arranged to form an “∞”-shaped structure. I am doing it. As a result, the force receiving area of the connector (2031) at the connection port (2013) is expanded as much as possible so that the pressures at the left and right ends of the connector (2031) are equalized. The second rubber washer (2037) is entirely laid on the inside of the connector (2031) and the surface parallel to the inside. Further, according to the aspect of the present invention, when a large amount of electric energy or electric signals to be transmitted is transmitted (for example, in the case of a high current charger that emphasizes fast charging or a transmitter that emphasizes a high throughput data stream), a power source When the connection device (200) requires a plurality of multiple pins for the connector (2031) or the connection port (2013), the number of vertical and horizontal bars may be supplemented according to the application needs. Good. As a result, a connector (2031) having a plurality of “∞”-shaped structures is formed in the power supply connection device (200), and the pressure of the connection port (2013) of the power supply connection device (200) is maintained at the same level, thereby sealing the device. The sex can be effectively improved. The waterproof structure provided by the present invention can satisfy the requirements of IPX4 or higher at a relatively economical cost. That is, based on the international protection grade (International Protection Marking, IP) certification standard, the power supply connection device (200) provided by the present invention provides a water pressure of 80 to 100 kPa, a water flow rate of 10 L/min, and continuous water sprinkling for 5 minutes. No damage when received. Also, the waterproof standard can be improved to the level of IPX8 according to the application needs. In an embodiment of the present invention, the hermeticity is in the range of low vacuum to medium vacuum, that is, between 10 and 750 Torr.
接続ケーブル（２０３）の組み立て過程を説明する図４Ａ〜図４Ｃを参照する。接続ケーブルハウジング（２０３３）は、製造時にインサート成形方式を採用する。第２ゴムワッシャ（２０３７）は製造時に予め金型内に配置されるため、金型を開いて接続ケーブルハウジング（２０３３）を取り出せば、第２ゴムワッシャ（２０３７）は自身の弾性によって第１横棒（２０３８）と第２横棒（２０３９）の構造に完全に適合可能となる。また、接続ケーブルハウジング（２０３３）の体積が縮小するとともに、製造精度を向上させられ、防水密封性も自ずと改善可能となる。これにより従来の防水構造ではゴムワッシャを接着剤は真空接着により装置の表面に直接貼り付けることから、防水効果が芳しくないとの欠点が改善される。また、本発明の他の実施例において、第１ゴムワッシャ（２０１１）と接続ポート（２０１３）の製造にインサート成形を採用してもよいが、これに限らない。 Please refer to FIG. 4A to FIG. 4C for explaining the assembling process of the connection cable (203). The connection cable housing (2033) adopts an insert molding method at the time of manufacturing. Since the second rubber washer (2037) is placed in the mold in advance at the time of manufacturing, if the mold is opened and the connection cable housing (2033) is taken out, the second rubber washer (2037) is elastically moved by the first lateral washer (2037). It is fully compatible with the structure of the bar (2038) and the second cross bar (2039). In addition, the volume of the connection cable housing (2033) is reduced, the manufacturing accuracy is improved, and the waterproof sealing property can be naturally improved. As a result, in the conventional waterproof structure, the rubber washer is directly adhered to the surface of the device by vacuum bonding of the adhesive, which improves the disadvantage that the waterproof effect is not good. In addition, in another embodiment of the present invention, insert molding may be used to manufacture the first rubber washer (2011) and the connection port (2013), but is not limited thereto.
