Description

本発明は、ケースの内部でシール材により封止された内部部品とその内部部品からケースの外部に延出した延出部品とを含む防水コネクタのような装置（ここでは、これを「コネクタ装置」と呼ぶ）、及びそれの製造方法に関する。   The present invention relates to a device such as a waterproof connector (here, referred to as “connector device”) including an internal component sealed with a sealing material inside the case and an extended component extending from the internal component to the outside of the case. And the manufacturing method thereof.

例えば特許文献１には、樹脂充填形電子回路装置が開示されている。その樹脂充填形電子回路装置は、多面体形状のケースと、ケースの内部に配置された回路基板と、回路基板に接続されかつケースの外部に突出したコネクタと、ケースの内部に充填され硬化した樹脂とを含んでいる。コネクタは、ケースの側壁に形成した嵌合部に嵌合した状態でケースに保持されている。樹脂は、ケースの上面に形成した大きな開口を通してケースの内部に充填される。即ち、コネクタは、ケースの樹脂を充填するための開口とは異なる面から引き出されている。   For example, Patent Document 1 discloses a resin-filled electronic circuit device. The resin-filled electronic circuit device includes a polyhedral case, a circuit board disposed inside the case, a connector connected to the circuit board and protruding outside the case, and a resin that is filled and cured inside the case. Including. The connector is held by the case in a state of being fitted to a fitting portion formed on the side wall of the case. The resin is filled into the case through a large opening formed in the upper surface of the case. That is, the connector is drawn out from a surface different from the opening for filling the resin of the case.

特開平６−１７６８０９号公報JP-A-6-176809

特許文献１においては、ケースの内部に充填された樹脂が、硬化の前に、ケースの側壁の嵌合部とコネクタとの隙間から漏出することが懸念される。そのため、ケースの側壁の嵌合部とコネクタとの隙間を塞ぐシール構造が必要となる。シール構造としては、例えばその隙間にシーリング剤やオーリングなどを備えることが考えられる。   In Patent Document 1, there is a concern that the resin filled in the case leaks from the gap between the fitting portion on the side wall of the case and the connector before curing. Therefore, a seal structure that closes the gap between the fitting portion on the side wall of the case and the connector is required. As a sealing structure, for example, it is conceivable to provide a sealing agent or an O-ring in the gap.

しかし、それらのシール構造は全体構造を複雑化させるため、製造工程も複雑になり、望ましくない。   However, these seal structures complicate the overall structure, which complicates the manufacturing process and is undesirable.

それ故に本発明の課題は、コネクタ装置の製造が容易な製造方法を提供することにある。 Problems of invention therefore is that the manufacture of the connector device to provide an easy manufacturing method.

本発明の一態様によれば、ケース、前記ケースの内部に配置された内部部品、前記内部部品から前記ケースの外部に延出した延出部品、及び前記ケースの内部に充填されて固化したシール材を含むコネクタ装置を製造する方法であって、前記内部部品が通過可能な開口部と前記シール材を注入可能な注入口とを互いに異なる面に有する多面体形状のケース本体を用意する準備工程、前記開口部を通して前記内部部品を前記ケース本体内に配置する部品配置工程、前記部品配置工程の後に、前記開口部を覆うように前記ケース本体にカバーを当てて治具で押さえて前記ケース本体と前記カバーとの段差の無い平面同士を密着させ、前記ケース本体と前記カバーとの間にシール面を形成する閉口工程、前記閉口工程の後に、前記注入口を通して前記シール材を前記ケース本体内に注入する注入工程、及び前記ケース本体内に注入されたシール材を硬化させ、前記カバーを前記ケース本体に固着させて前記ケースを形成する硬化工程を含み、前記治具は加熱装置を有するものであり、前記加熱装置により前記硬化工程を実行することを特徴とする製造方法が得られる。 According to one aspect of the present invention, a case, an internal part disposed inside the case, an extended part extending from the internal part to the outside of the case, and a seal that is filled and solidified inside the case A method for manufacturing a connector device including a material, comprising preparing a polyhedral case body having an opening through which the internal component can pass and an injection port through which the sealing material can be injected on different surfaces; A component placement step for placing the internal component in the case body through the opening, and after the component placement step, a cover is applied to the case body so as to cover the opening, and is pressed by a jig and the case body. A closing step in which flat surfaces having no step with the cover are brought into close contact with each other and a sealing surface is formed between the case body and the cover, and after the closing step, through the inlet. An injection step of injecting a sealing material into the case body; and a curing step of hardening the sealing material injected into the case body and fixing the cover to the case body to form the case. The tool has a heating device, and the manufacturing method is characterized in that the curing step is performed by the heating device.

本発明の製造方法によれば、カバーを押える治具が加熱装置を兼ねることになるので、コネクタ装置の製造工程を簡略化できる。 According to the manufacturing method of the present invention, since the jig for pressing the cover also serves as the heating device, the manufacturing process of the connector device can be simplified .

図１〜図４を参照して、本発明の第１の実施の形態に係るコネクタ装置の製造方法について説明する。 Referring to FIGS. 1 to 4, it described manufacturing method of the connector according to the first embodiment of the present invention.

概略構成を示す図１を参照すると、コネクタ装置は、ユニットケース（以下、単に「ケース」という）１、そのケース１の内部に配置された回路基板などの内部部品２、その内部部品２からケース１の外部に延出した延出部品としてのケーブル３、及びケース１の内部に充填されて固化したシール材４を含んでいる。シール材４としては、例えばポッティング剤などと呼ばれる通常は液体状又はゲル状を呈するシリコン系の熱硬化性の樹脂を用いることができる。   Referring to FIG. 1 showing a schematic configuration, a connector device includes a unit case (hereinafter simply referred to as “case”) 1, an internal component 2 such as a circuit board disposed in the case 1, and the internal component 2 to the case. 1 includes a cable 3 as an extended part extending to the outside of 1, and a sealing material 4 filled and solidified inside the case 1. As the sealing material 4, for example, a silicon-based thermosetting resin usually called liquid or gel called a potting agent can be used.

具体的構成を示す図２及び図３をも参照すると、ケース１は、多面体形状即ち六面体形状のケース本体５を含んでいる。ケース本体５は、内部部品２が通過可能な比較的大きい開口部６と、未硬化のシール材４を注入可能な比較的小さい注入口７とを互いに隣接した異なる面に有している。即ち、開口部６はケース本体５の一側面に形成され、注入口７はケース本体５の上面に形成されている。ただし、図２及び図３に示した構成では、開口部６及び注入口７は互いに繋がっている。   2 and 3 showing the specific configuration, the case 1 includes a case body 5 having a polyhedral shape, that is, a hexahedral shape. The case body 5 has a relatively large opening 6 through which the internal component 2 can pass and a relatively small inlet 7 through which the uncured sealing material 4 can be injected on different surfaces adjacent to each other. That is, the opening 6 is formed on one side surface of the case body 5, and the inlet 7 is formed on the upper surface of the case body 5. However, in the configuration shown in FIGS. 2 and 3, the opening 6 and the injection port 7 are connected to each other.

ケース１は、さらに、ケース本体５の開口部６を覆ったカバー８を含んでいる。カバー８は、固化したシール材４によりケース本体５に固着されている。   The case 1 further includes a cover 8 that covers the opening 6 of the case body 5. The cover 8 is fixed to the case main body 5 by the solidified sealing material 4.

ケーブル３は、ケース本体５の注入口７を有する面から引き出されている。具体的には、ケース本体５の注入口７を通してケーブル３がケース１の外部に引き出されている。   The cable 3 is drawn from the surface of the case body 5 having the inlet 7. Specifically, the cable 3 is drawn out of the case 1 through the inlet 7 of the case body 5.

上述したコネクタ装置は次に説明する複数の工程を含む製造方法によって製造することができる。   The connector device described above can be manufactured by a manufacturing method including a plurality of steps described below.

まず準備工程において、開口部６と注入口７とを互いに異なる面に有する六面体形状のケース本体５を用意する。次に部品配置工程において、開口部６を通して内部部品２をケース本体５内に配置すると共に、ケーブル３を注入口７に挿入する。部品配置工程の後に、開口部６を覆うようにケース本体５にカバー８を当てて仮装着し、さらに治具（ここでは図示せず）によって、図１に白抜き矢印Ａ１で示すようにカバー８を押してケース本体５に密着させて保持する。こうして閉口工程を実行する。このように治具でカバー８をケース本体５に押圧させる場合には、カバー８として平坦な板材を使用して、部品の単純化を図ることができる。   First, in the preparation step, a hexahedron-shaped case body 5 having an opening 6 and an inlet 7 on different surfaces is prepared. Next, in the component placement step, the internal component 2 is placed in the case body 5 through the opening 6 and the cable 3 is inserted into the inlet 7. After the component placement step, the cover 8 is temporarily attached by covering the case body 5 so as to cover the opening 6, and further covered with a jig (not shown here) as shown by a white arrow A1 in FIG. 8 is pressed and held in close contact with the case body 5. Thus, the closing process is performed. When the cover 8 is pressed against the case body 5 with a jig in this way, a flat plate material can be used as the cover 8 to simplify the parts.

ケース本体５とカバー８との段差の無い平面同士の面圧により一時的なシール面９が発生する。この面圧によるシール面９が未硬化のシール材の流出を防ぐため、ケース本体５には自由な方向に向けて注入口７を設計することが可能である。また、組み立て時に治具による押し付けの保持だけでケース本体５とカバー８とを固定するため、各々の部品にお互いの保持構造を持たせる必要がなく、簡単な構造にすることができる。   A temporary sealing surface 9 is generated by the surface pressure between the flat surfaces of the case body 5 and the cover 8 without any step. Since the sealing surface 9 due to this surface pressure prevents the uncured sealing material from flowing out, it is possible to design the inlet 7 in the case body 5 in a free direction. Further, since the case main body 5 and the cover 8 are fixed only by holding by pressing with a jig at the time of assembly, it is not necessary to provide each part with a holding structure for each part, and a simple structure can be achieved.

閉口工程の後に、図１に矢印Ａ２で示すように注入口７を通して未硬化のシール材４をケース本体５内に注入する注入工程を実行する。ケーブル３がケース本体５の注入口７を通して引き出された構造であるため、ケース１の内部の防水が容易に可能である。   After the closing step, an injection step for injecting the uncured sealing material 4 into the case body 5 through the injection port 7 as shown by an arrow A2 in FIG. Since the cable 3 is drawn out through the inlet 7 of the case body 5, the inside of the case 1 can be easily waterproofed.

最後に、ケース本体５内に注入されたシール材４を硬化させる硬化工程を経ると、カバー８がケース本体５に固着され、両者によりケース１を形成する。なお、治具に加熱装置を設け、その加熱装置により硬化工程を実行するようにしてもよい。   Finally, after a curing process for curing the sealing material 4 injected into the case main body 5, the cover 8 is fixed to the case main body 5, and the case 1 is formed by both. Note that a heating device may be provided on the jig, and the curing process may be executed by the heating device.

図４に示すように、カバー８の少なくともシール材４に対向する面、即ち、内面に格子状の凹凸部１１を設け、カバー８が固化したシール材４によりケース本体５に強固に固着されるように構成することは好ましい。この場合、シール材４が硬化すると、凹凸部１１によりカバー８はシール材４を介してケース本体５に強固に接着され一体化されるため、カバー８とケース本体５との境界面は防水状態で保持される。なお、凹凸部１１の形状や寸法には様々な変形が可能であることは勿論である。   As shown in FIG. 4, at least the surface of the cover 8 facing the sealing material 4, that is, the inner surface is provided with a grid-like uneven portion 11, and the cover 8 is firmly fixed to the case body 5 by the solidified sealing material 4. Such a configuration is preferable. In this case, when the sealing material 4 is cured, the cover 8 is firmly bonded and integrated with the case main body 5 via the sealing material 4 by the concavo-convex portion 11, so that the boundary surface between the cover 8 and the case main body 5 is waterproof. Held in. Of course, the shape and dimensions of the concavo-convex portion 11 can be variously modified.

また、図５に示すように、ケース本体５の注入口７を形成した面にさらに引出口１２を設け、ケーブル３を引出口１２を通して引き出してもよい。このように、注入口７と引出口１２を同一面に設計すれば、注入口７と引出口１２とを共通化する必要は無い。また、注入口７から未硬化のシール材４を注入する際に、これに応じてケース１内の空気が引出口１２から外部に排出されるので、シール材４の注入作業を円滑に行うことができる。   In addition, as shown in FIG. 5, an outlet 12 may be further provided on the surface of the case body 5 where the inlet 7 is formed, and the cable 3 may be pulled out through the outlet 12. Thus, if the inlet 7 and the outlet 12 are designed on the same surface, there is no need to share the inlet 7 and the outlet 12. Further, when the uncured sealing material 4 is injected from the injection port 7, the air in the case 1 is discharged from the outlet 12 to the outside accordingly, so that the sealing material 4 can be injected smoothly. Can do.

図６及び図７を参照して、本発明の第２の実施の形態に係るコネクタ装置の製造方法について説明する。図２及び図３と同様な部分については同じ参照符号を付して説明を省略する。 With reference to FIG.6 and FIG.7 , the manufacturing method of the connector apparatus based on the 2nd Embodiment of this invention is demonstrated. Parts similar to those in FIGS. 2 and 3 are denoted by the same reference numerals and description thereof is omitted.

図示のコネクタ装置においては、回路基板などの内部部品２からケース１の外部に延出した延出部品として、内部部品２に接続されたコネクタ１３を用いている。また、開口部６はケース本体５の一側面に形成され、注入口７はケース本体５の上面に形成されているが、これらは互いに繋がっている。   In the illustrated connector device, a connector 13 connected to the internal component 2 is used as an extended component extending from the internal component 2 such as a circuit board to the outside of the case 1. The opening 6 is formed on one side surface of the case body 5 and the injection port 7 is formed on the upper surface of the case body 5, which are connected to each other.

内部部品２をケース本体５の内部に配置する際に、コネクタ１３を注入口７に挿入する。さらに、カバー８を開口部６を塞ぐようにケース本体５に当接させる。この状態で、ケース本体５及びカバー８を図８及び図９に示すように治具１４に装着する。具体的には、ケース本体５及びカバー８を治具１４の受け部１５とこれに対しスライド可能な押圧部１６との間に挿入配置する。そして、図８に白抜き矢印Ａ１で示すように押圧治具１５でカバー８をケース本体５に向けて押圧しつつ、注入口７から未硬化のシール材を注入する。コネクタ１３がケース本体５の注入口７を通して引き出された構造であるため、ケース１の内部の防水が容易に可能である。最後に、ケース本体５内に注入されたシール材４を硬化させる硬化工程を経ると、カバー８がケース本体５に固着され、両者によりケース１を形成する。なお、治具１４に加熱装置を設け、その加熱装置により硬化工程を実行するようにしてもよい。   When the internal component 2 is placed inside the case body 5, the connector 13 is inserted into the inlet 7. Further, the cover 8 is brought into contact with the case body 5 so as to close the opening 6. In this state, the case body 5 and the cover 8 are mounted on the jig 14 as shown in FIGS. Specifically, the case main body 5 and the cover 8 are inserted and arranged between the receiving portion 15 of the jig 14 and the pressing portion 16 that can slide relative to the receiving portion 15. Then, as shown by a white arrow A1 in FIG. 8, an uncured sealing material is injected from the injection port 7 while pressing the cover 8 toward the case body 5 with the pressing jig 15. Since the connector 13 has a structure drawn through the inlet 7 of the case body 5, the waterproofing of the inside of the case 1 can be easily performed. Finally, after a curing process for curing the sealing material 4 injected into the case main body 5, the cover 8 is fixed to the case main body 5, and the case 1 is formed by both. In addition, a heating device may be provided in the jig 14 and the curing process may be executed by the heating device.
