Abstract

PROBLEM TO BE SOLVED: To provide a protector capable of reducing weight, improving a degree of shape freedom, and improving shield performance.SOLUTION: A protector 20 for covering an outer periphery of a connector device 1 includes: a resin body part 25 formed of a synthetic resin material; and a conductive coating layer 26, formed of a conductive material, provided on an inner surface of the resin body part 25.

Description

本発明は、電子機器等の外周を被うプロテクタに関する。   The present invention relates to a protector covering an outer periphery of an electronic device or the like.

従来より種々の電子機器が提案されている（特許文献１参照）。電子機器には、機器の保護とシールドの両方を図るために、電子機器の外周をシールドシェル（プロテクタ）で被う構造のものがある。図８〜図１２には、かかる構造の一従来例が示されている。   Conventionally, various electronic devices have been proposed (see Patent Document 1). Some electronic devices have a structure in which the outer periphery of the electronic device is covered with a shield shell (protector) in order to protect and shield the device. 8 to 12 show a conventional example of such a structure.

図８〜図１２において、コネクタ装置５０は、第１コネクタ５１と、第１コネクタ５１に電線Ｗを介して接続された第２コネクタ５２と、これらの外周を被うシールド部材であるシールドシェル６０とを備えている。   8 to 12, the connector device 50 includes a first connector 51, a second connector 52 connected to the first connector 51 via an electric wire W, and a shield shell 60 that is a shield member covering the outer periphery thereof. And.

シールドシェル６０は、第１コネクタ５１と電線Ｗの上部側を覆う第１ロアシールドシェル部材６１及び第１アッパーシールドシェル部材６２と、第２コネクタ５２と電線Ｗの下部側を覆う第２ロアシールドシェル６３部材及び第２アッパーシールドシェル部材６４とを備えている。これらシールドシェル部材６１〜６４は、鉄板（ＳＰＣＥ）等の金属材よりプレス成形でそれぞれ形成されている。   The shield shell 60 includes a first lower shield shell member 61 and a first upper shield shell member 62 that cover the upper side of the first connector 51 and the electric wire W, and a second lower shield that covers the lower side of the second connector 52 and the electric wire W. A shell 63 member and a second upper shield shell member 64 are provided. These shield shell members 61 to 64 are each formed by press molding from a metal material such as an iron plate (SPCE).

第２アッパーシールドシェル部材６４には、図１３に詳しく示すように、切欠部６４ａが形成されている。この切欠部６４ａは、プレス加工上の必要性から形成されている。   As shown in detail in FIG. 13, the second upper shield shell member 64 is formed with a notch 64 a. This notch 64a is formed because of the necessity for press working.

特開２００６−３４４３９３号公報JP 2006-344393 A

しかしながら、前記従来例では、シールドシェル６０を構成する各シールドシェル部材６１〜６４が鉄板等の金属材より形成されているため、シールドシェル６０が重量化する。これにより、電子機器であるコネクタ装置５０の重量が重くなる。又、各シールドシェル部材６１〜６４は、プレス加工で形成されるため、プレス加工上の制約（絞り深さ、絞り方向）を受けるため、形状の自由度が低い。更に、第２アッパーシールドシェル部材６４のように切欠部６４ａを形成する場合には、切欠部６４ａがシールド性能の低減を招来する。   However, in the conventional example, each shield shell member 61 to 64 constituting the shield shell 60 is formed of a metal material such as an iron plate, so that the shield shell 60 is weighted. Thereby, the weight of the connector apparatus 50 which is an electronic device becomes heavy. Moreover, since each shield shell member 61-64 is formed by press work, since it receives restrictions on press work (drawing depth, drawing direction), the degree of freedom in shape is low. Furthermore, when forming the notch part 64a like the 2nd upper shield shell member 64, the notch part 64a invites reduction of a shield performance.

そこで、本発明は、前記した課題を解決すべくなされたものであり、軽量化と形状自由度の向上とシールド性能の向上を図ることができるプロテクタを提供することを目的とする。   Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a protector capable of achieving weight reduction, improvement in shape freedom, and improvement in shielding performance.

本発明は、電子機器の外周を被うプロテクタであって、合成樹脂材より形成された樹脂本体部と、導電性材より形成され、前記樹脂本体部の内面と外面の少なくともいずれか一方に設けられた導電性皮膜層とを備えたことを特徴とするプロテクタである。   The present invention is a protector for covering the outer periphery of an electronic device, which is formed of a resin main body portion formed of a synthetic resin material and a conductive material, and is provided on at least one of the inner surface and the outer surface of the resin main body portion. And a conductive film layer formed thereon.

前記樹脂本体部は、着色された合成樹脂材より形成され、前記導電性皮膜層は、前記樹脂本体部の内面に設けられることが好ましい。取付部には、前記ボルト挿通穴を有するカラーが埋設されていることが好ましい。前記カラーは、導電性材より形成され、前記樹脂本体部側の面より突出されていることが好ましい。前記電子機器は、コネクタ装置である場合を含む。   It is preferable that the resin main body is formed of a colored synthetic resin material, and the conductive coating layer is provided on the inner surface of the resin main body. It is preferable that a collar having the bolt insertion hole is embedded in the mounting portion. The collar is preferably formed of a conductive material and protrudes from the surface of the resin main body. The electronic device includes a case where it is a connector device.

本発明によれば、プロテクタは、合成樹脂材より形成された樹脂本体部を有するため、軽量化を図ることができる。又、プロテクタの樹脂本体部は、形状制約がプレス加工に較べて遙かに少ない合成樹脂の射出成形で作製できるため、形状の自由度が高い。更に、射出成形上の理由から切欠部を形成する必要性もプレス加工に較べて遥かに少ないため、シールド性能が向上する。以上より、軽量化と形状自由度の向上とシールド性能の向上を図ることができる。   According to the present invention, since the protector has the resin main body portion formed of the synthetic resin material, the weight can be reduced. Moreover, since the resin main body part of a protector can be produced by the injection molding of a synthetic resin whose shape restrictions are much smaller than that of press processing, the degree of freedom in shape is high. Furthermore, the necessity for forming a notch for the reason for injection molding is far less than that of press working, so that the shielding performance is improved. As described above, it is possible to reduce the weight, improve the degree of freedom in shape, and improve the shielding performance.

以下、本発明の一実施形態を図面に基づいて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１〜図７は本発明の一実施形態を示す。図１〜図３に示すように、電子機器であるコネクタ装置１は、第１コネクタ２と、第１コネクタ２に電線Ｗを介して接続された第２コネクタ１０と、第１コネクタ２、電線Ｗ及び第２コネクタ１０の外周を被うプロテクタ２０とを備えている。   1 to 7 show an embodiment of the present invention. As shown in FIGS. 1 to 3, a connector device 1 that is an electronic device includes a first connector 2, a second connector 10 connected to the first connector 2 via an electric wire W, a first connector 2, and an electric wire.

An LA terminal (not shown) fixed to an electric wire (not shown) on one side is connected to each connection terminal 4 of the first connector 2 by screwing or the like.

第２コネクタ１０は、複数の接続用開口１１ａを有するハウジング１１と、接続用開口１１ａ内に配置された複数の接続端子１２とを備えている。第２コネクタ１０の各接続端子１２には、他方方側の電線（図示せず）に固定されたＬＡ端子（図示せず）がネジ止め等によって接続される。   The second connector 10 includes a housing 11 having a plurality of connection openings 11a and a plurality of connection terminals 12 disposed in the connection openings 11a. An LA terminal (not shown) fixed to the other side electric wire (not shown) is connected to each connection terminal 12 of the second connector 10 by screwing or the like.

プロテクタ２０は、第１コネクタ２と電線Ｗの上部側を覆う第１ロアプロテクタ部材２１及び第１アッパープロテクタ部材２２と、第２コネクタ１０と電線Ｗの下部側を覆う第２ロアプロテクタ部材２３及び第２アッパープロテクタ部材２４とを備えている。   The protector 20 includes a first lower protector member 21 and a first upper protector member 22 that cover the upper side of the first connector 2 and the electric wire W, a second lower protector member 23 that covers the lower side of the second connector 10 and the electric wire W, and And a second upper protector member 24.

第１ロアプロテクタ部材２１と第１アッパープロテクタ部材２２は、第１コネクタ２の接続用開口３ａを除く外周を被っている。第２ロアプロテクタ部材２３と第２アッパープロテクタ部材２４は、第２コネクタ１０のコネクタ嵌合箇所を除く外周をほぼ被っている。   The first lower protector member 21 and the first upper protector member 22 cover the outer periphery excluding the connection opening 3 a of the first connector 2. The second lower protector member 23 and the second upper protector member 24 substantially cover the outer periphery excluding the connector fitting portion of the second connector 10.

次に、各プロテクタ部材２１〜２４の構成を、第２ロアプロテクタ部材２３を例に説明する。第２ロアプロテクタ部材２３は、図６（ａ）、（ｂ）に示すように、合成樹脂材より形成された樹脂本体部２５と、この樹脂本体部２５の内面に設けられた導電性皮膜層２６の二層構造である。   Next, the structure of each protector member 21-24 is demonstrated to the 2nd lower protector member 23 as an example. As shown in FIGS. 6A and 6B, the second lower protector member 23 includes a resin main body portion 25 formed of a synthetic resin material, and a conductive coating layer provided on the inner surface of the resin main body portion 25. 26 double-layer structure.

樹脂本体部２５は、着色された合成樹脂より形成されている。着色の色は、他のコネクタ装置１との識別を行うことができる色に設定されている。導電性皮膜層２６は、導電性材の金属材より形成されている。導電性皮膜層２６は、樹脂メッキ、蒸着、導電塗料の塗布、スパッタリングなどで形成されている。第２ロアプロテクタ部材２３は、ベースプロテクタ部２３ａと、このベースプロテクタ部２３ａに対し斜め方向に傾斜している傾斜プロテクタ部２３ｂを有する。ベースプロテクタ部２３ａと傾斜プロテクタ部２３ｂの境界箇所には補強リブ２３ｃが設けられている。ベースプロテクタ部２３ａの複数箇所には、取付部２３ｄが突設されている。各取付部２４ｄには、図７（ａ）、（ｂ）に詳しく示すように、カラー（スペーサ）２７が埋設されている。カラー２７は、導電金属製のリング状で、その中心穴がボルト挿通穴２７ａである。カラー２７の内面にも導電性皮膜層２６が形成されている。カラー２７の樹脂本体部２５側は、樹脂本体部２５の表面よりｄだけ突出している。   The resin main body 25 is formed from a colored synthetic resin. The color of coloring is set to a color that can be distinguished from other connector devices 1. The conductive coating layer 26 is formed of a conductive metal material. The conductive coating layer 26 is formed by resin plating, vapor deposition, application of conductive paint, sputtering, or the like. The 2nd lower protector member 23 has the base protector part 23a and the inclination protector part 23b which inclines in the diagonal direction with respect to this base protector part 23a. Reinforcing ribs 23c are provided at the boundary between the base protector portion 23a and the inclined protector portion 23b. At a plurality of locations of the base protector portion 23a, mounting portions 23d are projected. As shown in detail in FIGS. 7A and 7B, a collar (spacer) 27 is embedded in each mounting portion 24d. The collar 27 is a ring shape made of a conductive metal, and the center hole is a bolt insertion hole 27a. A conductive coating layer 26 is also formed on the inner surface of the collar 27. The resin main body 25 side of the collar 27 protrudes from the surface of the resin main body 25 by d.

第２ロアプロテクタ部材２３は、取付部２３ｄを被取付部（図示せず）に配置し、樹脂本体部２５側からボルト（図示せず）をボルト挿通穴２７ａに通して被取付部（図示せず）に螺入することによって固定される。導電性皮膜層２６は、カラー２７、ボルト（図示せず）、被取付部（図示せず）等をアース経路としてアース接続される。   In the second lower protector member 23, the mounting portion 23d is disposed on the mounted portion (not shown), and a bolt (not shown) is passed through the bolt insertion hole 27a from the resin main body 25 side to be mounted (not shown). It is fixed by screwing in. The conductive coating layer 26 is grounded using a collar 27, a bolt (not shown), a mounted portion (not shown), etc. as a ground path.

以上説明したように、プロテクタ２０を構成する各プロテクタ部材２１〜２４は、合成樹脂材より形成された樹脂本体部２５と、樹脂本体部２５の内面に設けられた導電性皮膜層２６とを有する。従って、プロテクタ２０は、樹脂本体部２５の強度によって第１コネクタ２等を保護すると共に、導電性皮膜層２６によって内外からの電磁波を遮蔽するため、シールド性能を有する。   As described above, each protector member 21 to 24 constituting the protector 20 has the resin main body portion 25 formed of a synthetic resin material and the conductive coating layer 26 provided on the inner surface of the resin main body portion 25. . Accordingly, the protector 20 protects the first connector 2 and the like by the strength of the resin main body 25 and shields electromagnetic waves from inside and outside by the conductive coating layer 26, and thus has a shielding performance.

プロテクタ２０は、主に合成樹脂材より形成された樹脂本体部２５で形成されるため、軽量化になる。これにより、コネクタ装置１の軽量化を図ることができる。又、樹脂本体部２５は、形状制約がプレス加工に較べて遙かに少ない合成樹脂の射出成形で作製できるため、形状の自由度が高い。更に、射出成形上の理由から切欠部を形成する必要性もプレス加工に較べて遥かに少ないため、第１コネクタ２等を極力隙間なく被うことができ、シールド性能が向上する。以上より、プロテクタ２０の軽量化と形状自由度の向上とシールド性能の向上を図ることができる。   Since the protector 20 is formed by the resin main body 25 mainly formed of a synthetic resin material, the weight is reduced. Thereby, weight reduction of the connector apparatus 1 can be achieved. Further, the resin main body 25 can be manufactured by injection molding of a synthetic resin, which has much less shape restrictions than press processing, and thus has a high degree of freedom in shape. Furthermore, since the necessity of forming a notch for the reason for injection molding is far less than that of press working, the first connector 2 and the like can be covered with no gap as much as possible, and the shielding performance is improved. As described above, it is possible to reduce the weight of the protector 20, improve the degree of freedom in shape, and improve the shielding performance.

その上、プロテクタ２０の樹脂本体部２５は、樹脂成形されるため、従来例で必要であったエッジ処理が不要である。   In addition, since the resin main body portion 25 of the protector 20 is resin-molded, the edge processing that is necessary in the conventional example is unnecessary.

樹脂本体部２５は、着色された合成樹脂材より形成され、導電性皮膜層２６は、樹脂本体部２５の内面に設けられている。従って、プロテクタ２０の識別機能とシールド性能を両立させることができる。識別機能を持たせる必要がない場合には、導電性皮膜層２６を樹脂本体部２５の外面に設けても良く、又、樹脂本体部２５の内面と外面の両方に導電性皮膜層２６を設けても良い。   The resin main body portion 25 is formed from a colored synthetic resin material, and the conductive coating layer 26 is provided on the inner surface of the resin main body portion 25. Therefore, it is possible to achieve both the identification function of the protector 20 and the shielding performance. When it is not necessary to provide an identification function, the conductive coating layer 26 may be provided on the outer surface of the resin main body 25, or the conductive coating layer 26 is provided on both the inner and outer surfaces of the resin main body 25. May be.

各プロテクタ２０の取付部２３ｄには、ボルト挿通穴２７ａを有するカラー２７が埋設されている。従って、ボルト締結力等による樹脂本体部２５の割れを防止できる。   A collar 27 having a bolt insertion hole 27 a is embedded in the mounting portion 23 d of each protector 20. Accordingly, it is possible to prevent the resin main body portion 25 from being cracked by a bolt fastening force or the like.

カラー２７は、導電性材より形成され、樹脂本体部２５側の面より突出している。従って、ボルト（図示せず）の締結力が樹脂本体部２５に作用するのを防止できる。又、締結されたボルト（図示せず）とカラー２７が電気的に確実に接触するため、この実施形態のように、ボルト（図示せず）とカラー２７をアース経路として利用できる。   The collar 27 is formed of a conductive material and protrudes from the surface on the resin main body 25 side. Therefore, it is possible to prevent a fastening force of a bolt (not shown) from acting on the resin main body portion 25. Further, since the fastened bolt (not shown) and the collar 27 are in reliable electrical contact, the bolt (not shown) and the collar 27 can be used as a ground path as in this embodiment.

この実施形態では、電子機器は、コネクタ装置１であるが、コネクタ装置１以外の電子機器でも本発明を適用できることはもちろんである。   In this embodiment, the electronic device is the connector device 1, but it goes without saying that the present invention can be applied to an electronic device other than the connector device 1.
