Description

本発明は、ケーブル同士の接続部を保護するクロージャカバー等に関するものである。   The present invention relates to a closure cover for protecting a connection portion between cables.

従来、光ファイバや電線などの各種のケーブルは、所定の間隔で接続されて用いられる。このようなケーブルの接続部を保護するために、当該接続部はクロージャに収容される。このようなクロージャは、通常水密に保たれ、内部に水が浸入しないように設計される。   Conventionally, various cables such as optical fibers and electric wires are used by being connected at predetermined intervals. In order to protect the connection part of such a cable, the connection part is accommodated in a closure. Such closures are usually designed to be kept watertight and prevent water from entering the interior.

クロージャを構成するクロージャカバーは、通常、半割構造の一対の本体部がヒンジで一体化されている。クロージャカバーの両端部には、端面板が収容される。端面板にはゴム部材が設けられており、クロージャカバーをケーブル等に固定すると、ゴム部材によってクロージャ内部への水の浸入が防止される。（例えば特許文献１、特許文献２）。   The closure cover constituting the closure usually has a pair of half-structured main body portions integrated with a hinge. End plates are accommodated at both ends of the closure cover. The end plate is provided with a rubber member, and when the closure cover is fixed to a cable or the like, the rubber member prevents water from entering the closure. (For example, patent document 1, patent document 2).

特開２００３−１５３４２４号公報JP 2003-153424 A 特開２００９−２３７３４０号公報JP 2009-237340 A

特許文献１、特許文献２に記載されたようなクロージャは、通常、以下のようにして用いられる。まず、ケーブル同士を接続し、トレイ等に収容する。次に、ケーブルの接続部を挟むように、一対の端面板をケーブルに固定する。すなわち、端面板に設けられたゴム部材をケーブルに固定する。次に、クロージャカバーをケーブルの接続部（トレイなど）とともに端面板を覆うように被せて固定する。以上により、クロージャが固定される。   The closures described in Patent Document 1 and Patent Document 2 are generally used as follows. First, the cables are connected and accommodated in a tray or the like. Next, the pair of end face plates are fixed to the cable so as to sandwich the connecting portion of the cable. That is, the rubber member provided on the end face plate is fixed to the cable. Next, the closure cover is covered and fixed so as to cover the end face plate together with the connection portion (tray or the like) of the cable. As described above, the closure is fixed.

しかし、従来の方法では、ゴム部材が端面板に固定されているため、一対の端面板をそれぞれ支持線等に固定し、さらにクロージャカバーを固定する必要があることから、作業工数を要する。また、端面板のピッチが所定範囲からずれると、クロージャカバーを装着することができず、作業のやり直しが生じる恐れがある。特に、通常、ゴム部材は低硬度であるため、端面板を固定した状態で、ケーブルに対する端面板の位置をずらそうとしても、ゴム部材が弾性変形するのみで、端面板の位置の微調整が困難である。   However, in the conventional method, since the rubber member is fixed to the end face plate, it is necessary to fix the pair of end face plates to the support line and the like, and further to fix the closure cover. Further, if the pitch of the end face plates deviates from a predetermined range, the closure cover cannot be attached, and there is a risk that the operation will be reworked. In particular, since the rubber member is usually low in hardness, even if it is attempted to shift the position of the end face plate with respect to the cable with the end face plate fixed, the rubber member is only elastically deformed, and the end face plate position can be finely adjusted. Have difficulty.

また、端面板はケーブル等を挟み込んだ状態で固定されるため、端面板には、端面板を閉じた状態で保持するための係合部が設けられる。しかし、この係合部を含めた端面板をクロージャカバー内に収容するため、必要以上にクロージャカバーの断面積を大きくする必要がある。   In addition, since the end face plate is fixed in a state where a cable or the like is sandwiched, the end face plate is provided with an engaging portion for holding the end face plate in a closed state. However, since the end face plate including the engaging portion is accommodated in the closure cover, it is necessary to increase the cross-sectional area of the closure cover more than necessary.

本発明は、このような問題に鑑みてなされたもので、取り付け作業性に優れたクロージャカバー等を提供することを目的とする。   The present invention has been made in view of such problems, and an object of the present invention is to provide a closure cover and the like excellent in attachment workability.

前述した目的を達成するため、第１の発明は、内部にケーブル接続部が収容されるクロージャカバーであって、一対の本体部と、一対の前記本体部を開閉可能に連結するヒンジ部と、前記本体部の両端部に設けられ、ケーブルが挿通されるケーブル挿通部と、前記ケーブル挿通部の内側に設けられるゴム部材収容部と、前記ゴム部材収容部に固定されるゴム部材と、を具備し、前記本体部を閉じると、それぞれの前記本体部に設けられた前記ゴム部材同士が密着して、前記ゴム部材によって前記ケーブル挿通部の水密を保つことができることを特徴とするクロージャカバーである。   In order to achieve the above-described object, the first invention is a closure cover in which a cable connecting portion is accommodated, and a pair of main body portions, a hinge portion that couples the pair of main body portions so as to be openable and closable, A cable insertion portion provided at both ends of the main body portion, through which a cable is inserted, a rubber member accommodation portion provided inside the cable insertion portion, and a rubber member fixed to the rubber member accommodation portion. And when the said main-body part is closed, the said rubber member provided in each said main-body part closely_contact | adheres, The watertight of the said cable insertion part can be maintained by the said rubber member, It is a closure cover characterized by the above-mentioned. .

前記ゴム部材収容部の内面と前記ゴム部材には、嵌合構造が設けられ、前記嵌合構造によって、前記ゴム部材が前記ゴム部材収容部に固定されてもよい。   A fitting structure may be provided on the inner surface of the rubber member housing portion and the rubber member, and the rubber member may be fixed to the rubber member housing portion by the fitting structure.

前記ヒンジ部は、前記本体部の長手方向に２列に形成され、それぞれの前記本体部の対向する位置に配置される前記ゴム部材は、別体で構成されてもよい。   The hinge portions may be formed in two rows in the longitudinal direction of the main body portion, and the rubber member disposed at a position facing each of the main body portions may be configured as a separate body.

前記ヒンジ部は、前記本体部の長手方向に２列に形成され、それぞれの前記本体部の対向する位置に配置される前記ゴム部材は、一体で構成されてもよい。   The hinge portions may be formed in two rows in the longitudinal direction of the main body portion, and the rubber members disposed at positions facing each of the main body portions may be integrally formed.

前記ゴム部材には、挿通されるケーブルの径に対応して薄肉部が設けられ、前記ヒンジ部の間隔は、前記薄肉部の径よりも広いことが望ましい。   The rubber member is preferably provided with a thin portion corresponding to the diameter of the inserted cable, and the interval between the hinge portions is preferably wider than the diameter of the thin portion.

前記ヒンジ部は、前記本体部の長手方向に１列に形成され、それぞれの前記本体部の対向する位置に配置される前記ゴム部材は、一体で構成されてもよい。   The hinge portions may be formed in a row in the longitudinal direction of the main body portion, and the rubber members disposed at positions facing each of the main body portions may be integrally formed.

第１の発明によれば、端面板を用いずにゴム部材とクロージャカバーとを一体で構成することで、端面板の固定作業が不要となり、また、端面板の位置調整も不要となる。このため、取り付け作業が容易となり、部品点数も削減することができる。   According to the first aspect of the present invention, the rubber member and the closure cover are integrally formed without using the end face plate, so that the fixing operation of the end face plate becomes unnecessary and the position adjustment of the end face plate becomes unnecessary. For this reason, attachment work becomes easy and the number of parts can also be reduced.

また、ゴム部材は、クロージャカバーの内面に形成された嵌合構造によって固定されるため、取扱い時などにおいて、ゴム部材がクロージャカバーから脱落することがない。   Further, since the rubber member is fixed by the fitting structure formed on the inner surface of the closure cover, the rubber member does not fall off the closure cover during handling.

クロージャカバーの本体部の開閉はヒンジ部で行われるが、この際、ヒンジ部は一列であっても２列であってもよい。ヒンジ部を２列とした場合には、ゴム部材をそれぞれの本体部に別体で収容してもよく、中央にゴム部材にもヒンジ部を形成して一体で構成してもよい。   The main body part of the closure cover is opened and closed by the hinge part. At this time, the hinge part may be one line or two lines. When the hinge portions are arranged in two rows, the rubber member may be accommodated separately in each main body portion, or the hinge portion may be formed in the rubber member at the center and may be configured integrally.

ヒンジ部を２本形成することで、クロージャカバーを開いた際に、ゴム部材とクロージャカバーのヒンジ部間との間に隙間が形成される。このため、ゴム部材でケーブル等を挟み込む際に、ゴム部材の変形を隙間で吸収することができる。このため、ケーブルを挟み込む際における、クロージャカバーを閉じる力が小さくて済む。特に、ヒンジ部間の距離がケーブルの径よりも大きければ、この効果が大きい。すなわち、ヒンジ部間の距離が、ゴム部材のケーブルを保持する部位である薄肉部の径よりも大きければ、特に有効である。   By forming two hinge portions, a gap is formed between the rubber member and the hinge portion of the closure cover when the closure cover is opened. For this reason, when a cable or the like is sandwiched between the rubber members, the deformation of the rubber members can be absorbed by the gaps. For this reason, when closing a cable, the force which closes a closure cover may be small. In particular, this effect is great if the distance between the hinge portions is larger than the diameter of the cable. That is, it is particularly effective if the distance between the hinge portions is larger than the diameter of the thin portion that is a portion for holding the cable of the rubber member.

なお、クロージャカバーのヒンジ部を１本とすれば、ゴム部材を一体化することが容易となる。   In addition, if the hinge part of a closure cover is made into one, it will become easy to integrate a rubber member.

第２の発明は、クロージャカバーの設置方法であって、一対の本体部と、一対の前記本体部を開閉可能に接続するヒンジ部と、前記本体部の両端部に設けられ、ケーブルが挿通されるケーブル挿通部と、前記ケーブル挿通部の内側に設けられるゴム部材収容部と、前記ゴム部材収容部に固定されるゴム部材と、を具備するクロージャカバーを用い、予め前記ゴム部材が取り付けられた前記クロージャカバーを、ケーブル接続部の上方から取り付け、前記本体部を閉じることで、それぞれの前記本体部に設けられた前記ゴム部材同士が密着して、前記ゴム部材によって前記ケーブル挿通部に挿通されるケーブルとの水密を保つことができることを特徴とするクロージャカバーの設置方法である。   A second invention is a method of installing a closure cover, which is provided at a pair of body parts, a hinge part that connects the pair of body parts so as to be openable and closable, and both ends of the body part, and a cable is inserted therethrough. The rubber member is attached in advance using a closure cover including a cable insertion portion, a rubber member accommodation portion provided inside the cable insertion portion, and a rubber member fixed to the rubber member accommodation portion. By attaching the closure cover from above the cable connecting portion and closing the main body portion, the rubber members provided in the main body portions are in close contact with each other, and are inserted into the cable insertion portion by the rubber member. This is a method of installing a closure cover, characterized in that it is possible to maintain watertightness with a cable.

第２の発明によれば、作業性に優れたクロージャカバーの設置方法を得ることができる。   According to the second invention, it is possible to obtain a method of installing a closure cover that is excellent in workability.

本発明によれば、取り付け作業性に優れたクロージャカバー等を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the closure cover etc. which were excellent in attachment workability | operativity can be provided.

以下、本発明の実施の形態にかかるクロージャカバー１について説明する。図１、図２はクロージャカバー１の外観を示す斜視図であり、図１は、閉じた状態を示す図、図２は開いた状態を示す図である。クロージャカバー１は、主に、一対の本体部２、ゴム部材７等から構成される。   Hereinafter, the closure cover 1 concerning embodiment of this invention is demonstrated. 1 and 2 are perspective views showing the appearance of the closure cover 1, FIG. 1 is a view showing a closed state, and FIG. 2 is a view showing an opened state. The closure cover 1 is mainly composed of a pair of main body portions 2, a rubber member 7, and the like.

クロージャカバー１は、電線や光ファイバなどのケーブルの接続部を保護する部材である。なお、以下の説明において、ケーブルとは、電線や光ファイバのみではなく、例えば、支持線や支持棒などのケーブル状の形態のものをすべて含むものとする。クロージャカバー１の本体部２は、箱状部材を略二分割した形状である。   The closure cover 1 is a member that protects connection portions of cables such as electric wires and optical fibers. In the following description, the cable includes not only an electric wire and an optical fiber but also all cable-like forms such as a support wire and a support rod. The main body 2 of the closure cover 1 has a shape obtained by dividing a box-shaped member into two substantially.

本体部２の上部には、ヒンジ部３が形成される。ヒンジ部３は、クロージャカバー１の長手方向に１本（１列）形成される。本体部２は、ヒンジ部３で連結されており、図２に示すように、ヒンジ部３を軸として開くことが可能である（図中矢印Ａ）。   A hinge portion 3 is formed on the upper portion of the main body portion 2. One hinge portion 3 is formed in the longitudinal direction of the closure cover 1 (one row). The main body 2 is connected by a hinge 3 and can be opened with the hinge 3 as an axis as shown in FIG. 2 (arrow A in the figure).

本体部２のヒンジ部３とは逆側の縁部近傍には、係合部９が設けられる。互いい対向する本体部２の互いの係合部９同士を係合することで、クロージャカバー１が閉じた状態で保持される。なお、係合部９の構造は互いに係合可能であれば、いずれの形態であってもよい。   An engaging portion 9 is provided in the vicinity of the edge of the main body 2 opposite to the hinge 3. By engaging the engaging portions 9 of the body portions 2 facing each other, the closure cover 1 is held in a closed state. In addition, as long as the structure of the engaging part 9 can be mutually engaged, any form may be sufficient.

本体部２の長手方向の両端面には、ケーブル挿通部５が設けられる。ケーブル挿通部５は、ケーブルが挿通される部位であって、半円状に端面の一部が切りかかれた形状である。図示した例では、ヒンジ部３を上部とし、係合部９を下部とした際に、ケーブル挿通部５が上下に２つ併設される。なお、ケーブル挿通部５の配置や個数は図示した例に限られない。   Cable insertion portions 5 are provided on both end surfaces of the main body portion 2 in the longitudinal direction. The cable insertion portion 5 is a portion through which the cable is inserted, and has a shape in which a part of the end surface is cut into a semicircular shape. In the illustrated example, when the hinge portion 3 is the upper portion and the engaging portion 9 is the lower portion, two cable insertion portions 5 are provided vertically. In addition, arrangement | positioning and the number of the cable penetration parts 5 are not restricted to the example shown in figure.

ケーブル挿通部５は、対向する本体部２の互いに対応した部位に形成され、クロージャカバー１を閉じた状態において、それぞれの本体部２のケーブル挿通部５が合わさって略円形となる。すなわち、ケーブル挿通部５の形状は、概ね挿通されるケーブルの形状に対応する。   The cable insertion portions 5 are formed in mutually corresponding portions of the main body portions 2 facing each other, and in a state where the closure cover 1 is closed, the cable insertion portions 5 of the main body portions 2 are combined to form a substantially circular shape. That is, the shape of the cable insertion portion 5 corresponds to the shape of the cable that is generally inserted.

クロージャカバー１の長手方向の両端部近傍であって、本体部２の内部には、ゴム部材７が収容される。ゴム部材７は低硬度のゲル状部材である。   A rubber member 7 is accommodated in the vicinity of both ends in the longitudinal direction of the closure cover 1 and inside the main body 2. The rubber member 7 is a low hardness gel-like member.

図３は、開いた状態のクロージャカバー１を示す平面図、図４（ａ）は、図３のＢ矢視図、図４（ｂ）は図３のＣ−Ｃ線断面図である。   3 is a plan view showing the closure cover 1 in an opened state, FIG. 4A is a view taken along arrow B in FIG. 3, and FIG. 4B is a cross-sectional view taken along line CC in FIG.

クロージャカバー１の両端部近傍であって、本体部２の内部には、それぞれゴム部材収容部２５が設けられる。すなわち、ケーブル挿通部５の内側には、ゴム部材収容部２５が設けられる。ゴム部材収容部２５には、それぞれゴム部材７が収容されて固定される。ゴム部材７の外形は、ゴム部材収容部２５の内形に対応する。また、ゴム部材７の一方の面は、本体部２の端面の内面に接触し、他方の面は、リブ１７に接触する。なお、ゴム部材７とゴム部材収容部２５との間の水密が十分確保できれば、ゴム部材７の外形は、必ずしもゴム部材収容部２５の内形と同一形状でなくてもよい。   In the vicinity of both end portions of the closure cover 1 and inside the main body portion 2, rubber member accommodating portions 25 are respectively provided. That is, the rubber member accommodating portion 25 is provided inside the cable insertion portion 5. Each rubber member 7 is accommodated and fixed in the rubber member accommodating portion 25. The outer shape of the rubber member 7 corresponds to the inner shape of the rubber member accommodating portion 25. Further, one surface of the rubber member 7 is in contact with the inner surface of the end surface of the main body 2, and the other surface is in contact with the rib 17. It should be noted that the outer shape of the rubber member 7 is not necessarily the same as the inner shape of the rubber member accommodating portion 25 as long as sufficient watertightness between the rubber member 7 and the rubber member accommodating portion 25 can be ensured.

なお、ゴム部材７と本体部２との水密を得るためには、ゴム部材７の外面がゴム部材収容部２５の内面と密着することが望ましい。すなわち、ゴム部材７は、ゴム部材収容部２５の大きさと同じかわずかに大きいことが望ましく、この場合、ゴム部材７がゴム部材収容部２５に押し込まれた状態となる。   In order to obtain watertightness between the rubber member 7 and the main body 2, it is desirable that the outer surface of the rubber member 7 is in close contact with the inner surface of the rubber member housing portion 25. That is, it is desirable that the rubber member 7 is the same as or slightly larger than the size of the rubber member accommodating portion 25. In this case, the rubber member 7 is pushed into the rubber member accommodating portion 25.

また、ゴム部材７によってケーブル等を挟み込んだ際に、ゴム部材７がケーブル等の軸方向に変形すると、ゴム部材７とケーブル等との密着性が悪くなる。このため、水密性が悪くなる恐れがある。したがって、ケーブル等の軸方向（クロージャカバー１の長手方向）へのゴム部材７の変形を抑制するためには、クロージャカバー１の端面とリブ１７を略同様の形状（高さ）で構成することが望ましい。すなわち、リブ１７にもケーブル挿通部を形成し、クロージャカバー１の端面とリブ１７とで、ゴム部材７の全体を挟み込むことが望ましい。   Moreover, when the rubber member 7 is sandwiched between the rubber member 7 and the rubber member 7 is deformed in the axial direction of the cable or the like, the adhesion between the rubber member 7 and the cable or the like is deteriorated. For this reason, there exists a possibility that watertightness may worsen. Therefore, in order to suppress deformation of the rubber member 7 in the axial direction of the cable or the like (longitudinal direction of the closure cover 1), the end surface of the closure cover 1 and the rib 17 are configured with substantially the same shape (height). Is desirable. That is, it is desirable to form a cable insertion part in the rib 17 and sandwich the entire rubber member 7 between the end face of the closure cover 1 and the rib 17.

ゴム部材収容部２５の内面には、嵌合爪１１が設けられる。また、ゴム部材７の嵌合爪１１に対応する部位には、貫通孔１９が設けられる。ゴム部材７をゴム部材収容部２５に収容した状態で、嵌合爪１１が貫通孔１９を貫通して、ゴム部材７と嵌合する。したがって、ゴム部材７がゴム部材収容部２５に固定される。なお、ゴム部材７とゴム部材収容部２５の嵌合構造は、図示した例に限られず、適宜設計される。例えば、ゴム部材７に突起爪を形成し、ゴム部材収容部２５に形成された貫通孔に嵌合させてもよい。   A fitting claw 11 is provided on the inner surface of the rubber member accommodating portion 25. Further, a through hole 19 is provided in a portion corresponding to the fitting claw 11 of the rubber member 7. In a state where the rubber member 7 is housed in the rubber member housing portion 25, the fitting claw 11 passes through the through hole 19 and fits with the rubber member 7. Accordingly, the rubber member 7 is fixed to the rubber member accommodating portion 25. In addition, the fitting structure of the rubber member 7 and the rubber member accommodating portion 25 is not limited to the illustrated example, and is appropriately designed. For example, a protrusion claw may be formed on the rubber member 7 and fitted into a through hole formed in the rubber member housing portion 25.

ゴム部材７のケーブルが挿通される部位には、薄肉部１３が設けられる。すなわち、本体部２のケーブル挿通部５に対応した位置に薄肉部１３が設けられる。   A thin portion 13 is provided at a portion of the rubber member 7 where the cable is inserted. That is, the thin portion 13 is provided at a position corresponding to the cable insertion portion 5 of the main body portion 2.

ゴム部材７は、クロージャカバー１のヒンジ部３に対応した位置に、ヒンジ部１５が設けられる。すなわち、それぞれの本体部２に収容されるゴム部材７はヒンジ部１５を介して一体で構成される。このため、クロージャカバー１をヒンジ部３で開閉すると、ゴム部材７もヒンジ部１５で開閉動作する。   The rubber member 7 is provided with a hinge portion 15 at a position corresponding to the hinge portion 3 of the closure cover 1. That is, the rubber member 7 accommodated in each main body 2 is integrally formed through the hinge 15. For this reason, when the closure cover 1 is opened and closed by the hinge portion 3, the rubber member 7 is also opened and closed by the hinge portion 15.

次に、クロージャカバー１の使用方法について説明する。図５は、クロージャカバー１を固定した状態を示す図である。図示した例では、支持線２１と光ファイバケーブル２３とが上下に１本ずつ配置される。   Next, a method for using the closure cover 1 will be described. FIG. 5 is a view showing a state in which the closure cover 1 is fixed. In the illustrated example, the support line 21 and the optical fiber cable 23 are arranged one above the other.

まず、光ファイバケーブル２３を通常の方法で接続する。光ファイバケーブル２３の接続部は、余長部を形成して支持線２１等に固定されたトレイ等に収容される。この状態で、クロージャカバー１を開いた状態で、光ファイバケーブル２３の接続部を覆うように、クロージャカバー１を上方から取り付ける。次に、クロージャカバー１を完全に閉じ、係合部９を係合させる。この際、支持線２１および光ファイバケーブル２３は、ケーブル挿通部５および薄肉部１３を貫通する。   First, the optical fiber cable 23 is connected by a normal method. The connection portion of the optical fiber cable 23 is accommodated in a tray or the like that forms an extra length portion and is fixed to the support line 21 or the like. In this state, with the closure cover 1 opened, the closure cover 1 is attached from above so as to cover the connection portion of the optical fiber cable 23. Next, the closure cover 1 is completely closed and the engaging portion 9 is engaged. At this time, the support wire 21 and the optical fiber cable 23 penetrate the cable insertion part 5 and the thin part 13.

以上、本実施の形態によれば、予めゴム部材７がクロージャカバー１に固定されているため、従来のように、端面板を支持線２１等に固定する必要がない。また、端面板のピッチをクロージャカバー１における端面板収容部のピッチに合わせる必要がないため、作業が容易である。また、端面板を用いないため、部品点数も少なくて済む。   As described above, according to the present embodiment, since the rubber member 7 is fixed to the closure cover 1 in advance, it is not necessary to fix the end face plate to the support line 21 or the like as in the prior art. Moreover, since it is not necessary to match the pitch of the end face plate with the pitch of the end face plate accommodating portion in the closure cover 1, the operation is easy. Further, since no end face plate is used, the number of parts can be reduced.

また、従来は、ある程度の剛性を有する端面板で、低硬度のゴム部材を保持することで、ゴム部材の変形を抑制していしていた。このため、ゴム部材で挟み込まれた支持線２１や光ファイバケーブル２３との水密を確保することができたが、端面板とクロージャカバーとの水密は十分に確保されていなかった。   Conventionally, a rubber member having a low hardness is held by an end face plate having a certain degree of rigidity to suppress deformation of the rubber member. For this reason, it was possible to ensure watertightness between the support wire 21 and the optical fiber cable 23 sandwiched between the rubber members, but watertightness between the end face plate and the closure cover was not sufficiently ensured.

本発明では、ゴム部材７は、ゴム部材７がクロージャカバー１と直接密着する。このため、ゴム部材７と、支持線２１および光ファイバケーブル２３との水密を確保することができるとともに、ゴム部材７とクロージャカバー１との間の水密を確保することができる。また、クロージャカバー１を閉じると、対向するそれぞれの本体部２内のゴム部材７の対向面が密着する。このため、ゴム部材７同士の合わせ部の水密を確保することができる。   In the present invention, the rubber member 7 is in direct contact with the closure cover 1. For this reason, while being able to ensure the watertightness of the rubber member 7, the support wire 21, and the optical fiber cable 23, the watertightness between the rubber member 7 and the closure cover 1 can be ensured. When the closure cover 1 is closed, the opposing surfaces of the rubber members 7 in the opposing main body portions 2 are in close contact with each other. For this reason, it is possible to ensure the watertightness of the mating portion between the rubber members 7.

また、ゴム部材７がヒンジ部１５で連結されているため、支持線２１等を挟み込む際に、支持線２１がゴム部材７同士の隙間に挟まることがない。   Further, since the rubber member 7 is connected by the hinge portion 15, the support wire 21 is not caught in the gap between the rubber members 7 when the support wire 21 or the like is sandwiched.

次に、第２の実施の形態について説明する。図６は、第２の実施の形態にかかるクロージャカバー１ａを示す断面図である。なお、以下の説明において、図１〜図５に示した構成と同様の機能を奏する構成については、図１〜図５と同一の符号を付し、重複する説明を省略する。   Next, a second embodiment will be described. FIG. 6 is a cross-sectional view showing a closure cover 1a according to the second embodiment. In the following description, components having the same functions as those shown in FIGS. 1 to 5 are denoted by the same reference numerals as in FIGS. 1 to 5, and redundant descriptions are omitted.

クロージャカバー１ａは、クロージャカバー１と略同様の構成であるが、ゴム部材７ａが用いられる点で異なる。ゴム部材７ａは、ゴム部材７とは異なり、ヒンジ部１５を有さない。すなわち、ゴム部材７ａは、対向するそれぞれの本体部２にそれぞれ別体として収容される。   The closure cover 1a has substantially the same configuration as the closure cover 1, but differs in that a rubber member 7a is used. Unlike the rubber member 7, the rubber member 7 a does not have the hinge portion 15. That is, the rubber member 7a is accommodated as a separate body in each opposing main body 2.

このように、第２の実施の形態にかかるクロージャカバー１ａであっても、クロージャカバー１とほぼ同様の効果を得ることができる。   Thus, even with the closure cover 1a according to the second embodiment, substantially the same effect as the closure cover 1 can be obtained.

次に、第３の実施の形態について説明する。図７は、第３の実施の形態にかかるクロージャカバー１ｂを示す斜視図であり、図８（ａ）は側面図、図８（ｂ）は断面図である。   Next, a third embodiment will be described. 7A and 7B are perspective views showing a closure cover 1b according to the third embodiment. FIG. 8A is a side view and FIG. 8B is a cross-sectional view.

クロージャカバー１ｂは、クロージャカバー１とほぼ同様の構成であるが、ヒンジ部３が２本（２列）形成される点で異なる。ヒンジ部３は、所定の間隔をあけて、クロージャカバー１ｂの長手方向に平行に形成される。ヒンジ部３の間は天面部４であり、それぞれのヒンジ部３において、天面部４と本体部２が開閉可能に連結する。   The closure cover 1b has substantially the same configuration as that of the closure cover 1, but differs in that two hinge portions 3 are formed (two rows). The hinge part 3 is formed in parallel with the longitudinal direction of the closure cover 1b at a predetermined interval. Between the hinge parts 3, it is the top surface part 4. In each hinge part 3, the top surface part 4 and the main-body part 2 are connected so that opening and closing is possible.

なお、図示した例では、ゴム部材７ａは、対向する本体部２にそれぞれ分割して収容されるが、ヒンジ部３に対応する部位にヒンジ部１５を２本設け、ゴム部材７ａ同士を連結して一体で構成してもよい。   In the illustrated example, the rubber member 7a is divided and accommodated in the opposing main body portion 2, but two hinge portions 15 are provided at portions corresponding to the hinge portion 3 to connect the rubber members 7a to each other. May be configured integrally.

図９は、クロージャカバー１ａとクロージャカバー１ｂの違いを示す図であり、図９（ａ）は、クロージャカバー１ａによって支持線２１を挟み込む状態を示す断面図、図９（ｂ）はクロージャカバー１ｂによって支持線２１を挟み込む状態を示す断面図である。   FIG. 9 is a diagram showing a difference between the closure cover 1a and the closure cover 1b. FIG. 9A is a cross-sectional view showing a state in which the support wire 21 is sandwiched by the closure cover 1a, and FIG. 9B is a diagram showing the closure cover 1b. It is sectional drawing which shows the state which pinches | interposes the support line 21 by.

図９（ａ）に示すように、ヒンジ部３が１本であるクロージャカバー１ａを支持線２１に被せる場合において、クロージャカバー１ａを閉じていくと、支持線２１にゴム部材７ａが接触する。この状態から、さらにクロージャカバー１ａを閉じようとすると、ゴム部材７ａの薄肉部１３に支持線２１が押し付けられて、ゴム部材７ａに力が加わる（図中矢印Ｆ）。このため、図示した状態から、クロージャカバー１ａを閉じようとすると、このゴム部材７ａに加わる力に打ち勝つような力が必要となる。   As shown in FIG. 9A, when the closure cover 1 a having one hinge portion 3 is put on the support line 21, the rubber member 7 a comes into contact with the support line 21 when the closure cover 1 a is closed. If the closure cover 1a is further closed from this state, the support wire 21 is pressed against the thin portion 13 of the rubber member 7a, and a force is applied to the rubber member 7a (arrow F in the figure). For this reason, if it is going to close the closure cover 1a from the state shown in figure, the force which overcomes the force added to this rubber member 7a is needed.

一方、図９（ｂ）に示すように、ヒンジ部３が２本であるクロージャカバー１ｂを支持線２１に被せる場合において、クロージャカバー１ｂを閉じていくと、図９（ａ）と同様に、支持線２１にゴム部材７ａが接触する。この状態から、さらにクロージャカバー１ａを閉じようとすると、ゴム部材７ａの薄肉部１３に支持線２１が押し付けられて、ゴム部材７ａに力が加わる（図中矢印Ｄ）。この際、天面部４の内面とゴム部材７ａとの間には、隙間が形成されている。このため、図示した状態から、クロージャカバー１ａを閉じようとした際に、ゴム部材７ａに加わる力が、ゴム部材７ａの変形（図中矢印Ｅ）によって吸収される。このため、クロージャカバー１ｂの固定作業が容易である。   On the other hand, as shown in FIG. 9 (b), when the closure cover 1b having two hinge portions 3 is put on the support line 21, when the closure cover 1b is closed, as in FIG. 9 (a), The rubber member 7a contacts the support wire 21. If the closure cover 1a is further closed from this state, the support wire 21 is pressed against the thin portion 13 of the rubber member 7a, and a force is applied to the rubber member 7a (arrow D in the figure). At this time, a gap is formed between the inner surface of the top surface portion 4 and the rubber member 7a. For this reason, when closing the closure cover 1a from the illustrated state, the force applied to the rubber member 7a is absorbed by the deformation of the rubber member 7a (arrow E in the figure). For this reason, it is easy to fix the closure cover 1b.

なお、このような効果を効率よく得るためには、天面部４の幅（すなわちヒンジ部３同士の間隔）を、挟み込むケーブル等の外径よりも大きくすることが望ましい。例えば、図示した例では、支持線２１の外径よりも、天面部４の幅を広くすることが望ましい。   In order to efficiently obtain such an effect, it is desirable to make the width of the top surface portion 4 (that is, the interval between the hinge portions 3) larger than the outer diameter of a cable or the like to be sandwiched. For example, in the illustrated example, it is desirable to make the width of the top surface portion 4 wider than the outer diameter of the support wire 21.

ここで、ゴム部材７ａには、挟み込まれるケーブル類の外径に応じて、薄肉部１３が形成される。したがって、クロージャカバー１ｂを閉じた際に、対向するゴム部材７ａ同士の接触によって形成される略円形の薄肉部１３の外径は、挟み込まれるケーブル等の外径に応じて設計される。このため、天面部４の幅は、薄肉部１３の外径よりも大きくすればよい。   Here, the thin part 13 is formed in the rubber member 7a according to the outer diameter of the cables to be sandwiched. Therefore, when the closure cover 1b is closed, the outer diameter of the substantially circular thin portion 13 formed by the contact between the opposing rubber members 7a is designed according to the outer diameter of a cable or the like to be sandwiched. For this reason, the width | variety of the top | upper surface part 4 should just be made larger than the outer diameter of the thin part 13. FIG.

このように、第３の実施の形態にかかるクロージャカバー１ｂであっても、クロージャカバー１等とほぼ同様の効果を得ることができる。   Thus, even the closure cover 1b according to the third embodiment can obtain substantially the same effect as the closure cover 1 and the like.

また、ヒンジ部３を２本設けて、ヒンジ部３の間に天面部４を形成することで、クロージャカバー１ｂを開いた状態において、ゴム部材７ａと天面部４との間に隙間を形成することができる。このため、支持線２１などのケーブルを挟み込む際に、ゴム部材７ａの変形を許容し、小さな力でクロージャカバー１ｂを閉じることができる。   Further, by providing two hinge portions 3 and forming the top surface portion 4 between the hinge portions 3, a gap is formed between the rubber member 7a and the top surface portion 4 in a state where the closure cover 1b is opened. be able to. For this reason, when the cable such as the support wire 21 is sandwiched, the deformation of the rubber member 7a is allowed, and the closure cover 1b can be closed with a small force.

特に、天面部４の幅を挟み込むケーブル等の外径よりも大きくすることで、より確実にこの効果を得ることができる。   In particular, this effect can be obtained more reliably by making the width of the top surface portion 4 larger than the outer diameter of a cable or the like that sandwiches the width of the top surface portion 4.
