Description

本発明は、引込線を固定する碍子を支持体で支持させるべく、碍子と支持体とを接続する引込線支持具に関する。   The present invention relates to a lead-in wire support tool for connecting a lever and a support body so that the support member supports the lever that fixes the lead-in wire.

従来、引込線を支持する方法として、図１０に示すように、引込線を固定する碍子６と、碍子６を支持体７に接続することにより、碍子６を支持体７で支持させる引込線支持具９とにより、引込線を支持する方法が知られている。斯かる引込線支持具９は、碍子６に取り付けられる碍子取付部９１と、支持体７に取り付けられる支持体取付部９２とを備え、碍子取付部９１及び支持体取付部９２は、金属線でリング状となるように形成されている（例えば、特許文献１及び２）。   Conventionally, as shown in FIG. 10, as a method for supporting the lead-in wire, an insulator 6 for fixing the lead-in wire, and a lead-in wire support 9 for supporting the insulator 6 by the support body 7 by connecting the insulator 6 to the support body 7. Thus, a method for supporting a lead-in wire is known. Such a lead-in wire support 9 includes an insulator attachment portion 91 attached to the insulator 6 and a support attachment portion 92 attached to the support body 7, and the insulator attachment portion 91 and the support body attachment portion 92 are made of metal wires. (For example, patent documents 1 and 2).

そして、斯かる引込線支持具９においては、支持体取付部９２が支持体７の取付孔７１に先端側から挿入された後に、引込線支持具９は、支持体取付部９２がリング状に形成される方向(図１０（ａ）におけるＢ矢印方向）に沿って、支持体７に対して相対的に（少なくとも１８０°）回転変位される。これにより、支持体取付部９２が取付孔７１に挿通した状態となるため、支持体取付部９２が取付孔７１に取り付けられることになる。   In the lead-in wire support 9, the support attachment portion 92 is formed in a ring shape after the support attachment portion 92 is inserted into the attachment hole 71 of the support 7 from the distal end side. Along the direction (B arrow direction in FIG. 10 (a)) relative to the support 7 (at least 180 °). As a result, since the support attachment portion 92 is inserted into the attachment hole 71, the support attachment portion 92 is attached to the attachment hole 71.

また、引込線が碍子６に固定されていない状態においては、図１０（ｂ）に示すように、碍子６は、碍子取付部９１がリング状に形成される方向（図１０（ｂ）におけるＣ矢印方向）に沿って、引込線支持具９に対して相対的に（少なくとも１８０°）回転変位される。これにより、碍子取付部９１が碍子６の取付孔６１に挿通した状態となるため、碍子取付部９１が取付孔６１に取り付けられることになる。   Further, in a state where the lead-in wire is not fixed to the insulator 6, as shown in FIG. 10B, the insulator 6 has a direction in which the insulator attachment portion 91 is formed in a ring shape (C arrow in FIG. 10B). (Direction) relative to the lead-in wire support 9 (at least 180 °). Thereby, since the insulator attachment part 91 is inserted into the attachment hole 61 of the insulator 6, the insulator attachment part 91 is attached to the attachment hole 61.

しかしながら、引込線が碍子６に固定されている場合、例えば、碍子６を支持していた既設の支持体７を交換する場合等においては、上記（図１０）のように、引込線支持具９を、碍子６や支持体７に取り付けることができない場合がある。具体的には、まず引込線支持具９を支持体７に取り付けた場合においては、碍子６が引込線により引っ張られ、且つ、引込線支持具９が支持体７に取り付けられているため、引込線支持具９と碍子６とを十分に相対的に回転変位させることができない。   However, when the lead-in wire is fixed to the insulator 6, for example, when replacing the existing support 7 that has supported the insulator 6, the lead-in wire support 9 is used as described above (FIG. 10). In some cases, it cannot be attached to the insulator 6 or the support 7. Specifically, when the lead-in wire support 9 is first attached to the support 7, since the insulator 6 is pulled by the lead-in wire and the lead-in wire support 9 is attached to the support 7, the lead-in wire support 9 And the insulator 6 cannot be sufficiently rotationally displaced.

他方、まず引込線支持具９を碍子６に取り付けた場合においては、碍子６及び引込線支持具９が引込線により引っ張られているため、引込線支持具９を支持体７に対して十分に相対的に回転変位させることができない。そして、このような場合には、引込線を碍子６から取り外す必要があるため、斯かる作業が煩雑となり、しかも、停電を伴う作業になった場合には、さらに非効率的である。   On the other hand, when the lead-in wire support 9 is first attached to the insulator 6, since the insulator 6 and the lead-in wire support 9 are pulled by the lead-in wire, the lead-in wire support 9 rotates sufficiently relative to the support 7. It cannot be displaced. In such a case, since it is necessary to remove the lead-in wire from the insulator 6, such work becomes complicated, and moreover, it is further inefficient when the work is accompanied by a power failure.

よって、本発明は、かかる事情に鑑み、引込線が碍子に固定された状態においても、支持体と碍子とに容易に取り付けることができる引込線支持具を提供することを課題とする。   Therefore, in view of such circumstances, an object of the present invention is to provide a lead-in wire support that can be easily attached to a support and a lever even when the lead-in wire is fixed to the lever.

本発明に係る引込線支持具は、引込線を固定する碍子を支持体で支持させるべく、碍子に取り付けられる碍子取付部と、支持体に取り付けられる支持体取付部とを備え、碍子と支持体とを接続する引込線支持具において、碍子取付部は、碍子に設けられる取付孔に先端側から差し入れられる差入部と、差入部が取付孔から抜けるのを防止すべく、取付孔から突出する差入部の先端側を掛止する掛止部とを備え、掛止部は、差入部を掛止する状態と、当該掛止を解除する状態とに切り替え可能に構成されることを特徴とする。   The lead-in wire support according to the present invention includes a lever attachment portion attached to the insulator and a support attachment portion attached to the support so that the insulator fixing the lead-in wire is supported by the support, and the insulator and the support. In the lead-in wire support to be connected, the insulator mounting portion includes an insertion portion that is inserted into the attachment hole provided in the insulator from the tip side, and a distal end of the insertion portion that protrudes from the attachment hole in order to prevent the insertion portion from coming out of the attachment hole. A latching portion that latches the side, and the latching portion is configured to be switchable between a state of latching the insertion portion and a state of releasing the latching.

本発明に係る引込線支持具によれば、掛止部は、差入部を掛止する状態と、当該掛止を解除する状態とに切り替えることができる。これにより、掛止部が差入部の掛止を解除する状態で、碍子に設けられる取付孔に差入部が先端側から差し入れられる。そして、掛止部が取付孔から突出する差入部の先端側を掛止することにより、差入部が取付孔から抜け出るのを防止できる。   According to the lead-in wire support according to the present invention, the latching portion can be switched between a state in which the insertion portion is latched and a state in which the latch is released. Thereby, in a state where the latching portion releases the latch of the insertion portion, the insertion portion is inserted into the attachment hole provided in the insulator from the distal end side. And it can prevent that an insertion part pulls out from an attachment hole by latching the front end side of the insertion part which a latching part protrudes from an attachment hole.

また、本発明に係る引込線支持具は、引込線を固定する碍子を支持体で支持させるべく、碍子に取り付けられる碍子取付部と、支持体に取り付けられる支持体取付部とを備え、碍子と支持体とを接続する引込線支持具において、支持体取付部は、支持体に設けられる取付孔に先端側から差し入れられる差入部と、差入部が取付孔から抜け出るのを防止すべく、取付孔から突出する差入部の先端側を掛止する掛止部とを備え、掛止部は、差入部を掛止する状態と、当該掛止を解除する状態とに切り替え可能に構成されることを特徴とする。   Moreover, the lead wire support tool which concerns on this invention is equipped with the insulator attachment part attached to an insulator, and the support body attachment part attached to a support body so that the insulator which fixes a lead wire may be supported with a support body, and an insulator and a support body In the lead-in wire support tool for connecting to the support wire, the support attachment portion protrudes from the attachment hole so as to prevent the insertion portion from being inserted into the attachment hole provided in the support member from the tip end side and the insertion portion from coming out of the attachment hole. A hook portion that hooks the distal end side of the insertion portion, and the hook portion is configured to be switchable between a state in which the insertion portion is hooked and a state in which the hook is released. .

本発明に係る引込線支持具によれば、掛止部は、差入部を掛止する状態と、当該掛止を解除する状態とに切り替えることができる。これにより、掛止部が差入部の掛止を解除する状態で、支持体に設けられる取付孔に差入部が先端側から差し入れられる。そして、掛止部が取付孔から突出する差入部の先端側を掛止することにより、差入部が取付孔から抜け出るのを防止できる。   According to the lead-in wire support according to the present invention, the latching portion can be switched between a state in which the insertion portion is latched and a state in which the latch is released. Thereby, in a state where the latching portion releases the latch of the insertion portion, the insertion portion is inserted into the attachment hole provided in the support body from the distal end side. And it can prevent that an insertion part pulls out from an attachment hole by latching the front end side of the insertion part which a latching part protrudes from an attachment hole.

また、本発明に係る引込線支持具においては、一本の金属線から形成され、金属線の一端部側で差入部を構成し、金属線の他端部側で掛止部を構成してもよい。   Moreover, in the lead-in wire support tool according to the present invention, it is formed from a single metal wire, and the insertion portion is configured on one end side of the metal wire, and the latching portion is configured on the other end side of the metal wire. Good.

斯かる構成の引込線支持具によれば、一本の金属線の一端部側で差入部が構成されると共に、一本の金属線の他端部側で掛止部が構成される。これにより、構成が簡易であり、製作コストを低減することもできる。   According to the lead-in wire support tool having such a configuration, the insertion portion is configured on one end portion side of one metal wire, and the latching portion is configured on the other end portion side of one metal wire. Thereby, the configuration is simple, and the manufacturing cost can be reduced.

以上の如く、本発明に係る引込線支持具によれば、引込線が碍子に固定された状態においても、支持体と碍子とに容易に取り付けることができるという優れた効果を奏する。   As described above, according to the lead-in wire support according to the present invention, there is an excellent effect that the lead-in wire can be easily attached to the support body and the lever even when the lead-in wire is fixed to the lever.

以下、本発明に係る引込線支持具における一実施形態について、図１〜図６を参酌して説明する。なお、図１〜図６において、図１０の符号と同一の符号を付した部分は、従来技術と同一の構成又は要素を表す。   Hereinafter, an embodiment of a lead-in wire support according to the present invention will be described with reference to FIGS. 1 to 6, the same reference numerals as those in FIG. 10 denote the same components or elements as those in the related art.

図１〜図３に示すように、本実施形態に係る引込線支持具１は、引込線５を固定する碍子６を支持体７で支持させるべく、碍子６に取り付けられる碍子取付部１１と、支持体７に取り付けられる支持体取付部１２とを備え、碍子６と支持体７とを接続する。ここで、引込線支持具１の各構成を説明するのに先立って、碍子６及び支持体７について説明する。   As shown in FIGS. 1 to 3, the lead-in wire support 1 according to the present embodiment includes a lever attachment portion 11 that is attached to the lever 6 and a support body so that the lever 6 that fixes the lead-in wire 5 is supported by the support body 7. 7 and a support attachment part 12 attached to 7, and the insulator 6 and the support 7 are connected to each other. Here, prior to describing each configuration of the lead-in wire support 1, the insulator 6 and the support 7 will be described.

碍子６は、引込線支持具１に取り付けられるための取付孔６１と、引込線５を固定すべく、本体部６２から突出する突出部６３，…とを備える。そして、碍子６は、突出部６３，…に引込線５を巻き付けることにより、引込線５を固定する。また、取付孔６１は、長穴状に形成されている。なお、碍子６は、一般的に、バンドレス碍子や、平型碍子と呼ばれている。   The insulator 6 includes an attachment hole 61 for attachment to the lead-in wire support 1, and protrusions 63,... That protrude from the main body portion 62 in order to fix the lead-in wire 5. Then, the insulator 6 fixes the lead-in wire 5 by winding the lead-in wire 5 around the protrusions 63. The attachment hole 61 is formed in a long hole shape. The insulator 6 is generally called a bandless insulator or a flat insulator.

支持体７は、引込線支持具１に取り付けられるための取付孔７１を備える。そして、支持体７は、引込線５が引き込まれる建物８に固定されている。なお、支持体７は、本実施形態のように、リング状の金具である場合に限られず、例えば、各種の型鋼（山形鋼、Ｈ鋼等）や管材等でもよい。要するに、支持体７は、建物８に固定され又は一体的に形成され、且つ、引込線支持具１に取り付けられるための取付孔７１を備えていればよい。   The support 7 includes an attachment hole 71 for attaching to the lead-in wire support 1. And the support body 7 is being fixed to the building 8 in which the lead-in wire 5 is drawn. In addition, the support body 7 is not limited to a ring-shaped metal fitting as in the present embodiment, and may be various types of steel (an angle steel, H steel, etc.), a pipe material, and the like. In short, the support body 7 should just be provided with the attachment hole 71 fixed to the building 8 or integrally formed, and attaching to the lead wire support tool 1. FIG.

碍子取付部１１は、碍子６の取付孔６１に先端側から差し入れられる差入部１１ａを備える。また、碍子取付部１１は、差入部１１ａが碍子６の取付孔６１から抜け出るのを防止すべく、碍子６の取付孔６１から突出する差入部１１ａの先端側を掛止する掛止部１１ｂを備える。そして、碍子取付部１１は、掛止部１１ｂが差入部１１ａを掛止する状態にて、環状（無端状）に構成される。   The insulator attachment portion 11 includes an insertion portion 11a that is inserted into the attachment hole 61 of the insulator 6 from the distal end side. In addition, the lever mounting portion 11 has a latching portion 11b that latches the distal end side of the insertion portion 11a protruding from the mounting hole 61 of the lever 6 in order to prevent the insertion portion 11a from coming out of the mounting hole 61 of the lever 6. Prepare. And the insulator attachment part 11 is comprised by the cyclic | annular form (endless form) in the state which the latching part 11b latches the insertion part 11a.

差入部１１ａは、円弧状に形成される。そして、差入部１１ａの先端部は、フック状に形成される。また、差入部１１ａは、先端側が碍子６の取付孔６１から突出すべく、高さ寸法が碍子６の高さ寸法よりも大きく形成される。   The insertion portion 11a is formed in an arc shape. And the front-end | tip part of the insertion part 11a is formed in a hook shape. Further, the insertion portion 11 a is formed with a height dimension larger than the height dimension of the insulator 6 so that the tip side protrudes from the attachment hole 61 of the insulator 6.

掛止部１１ｂの先端部は、フック状に形成され、差入部１１ａにおけるフック状に形成される先端部を掛止する。そして、掛止部１１ｂは、差入部１１ａと一体的に形成されると共に、差入部１１ａに対して接離可能（相対的に変位可能）に構成される。これにより、掛止部１１ｂは、差入部１１ａを掛止する状態と、当該掛止を解除する状態とに切り替え可能に構成される。   The distal end portion of the latching portion 11b is formed in a hook shape, and latches the distal end portion formed in the hook shape in the insertion portion 11a. And the latching | locking part 11b is comprised integrally with the insertion part 11a, and it is comprised by the insertion part 11a so that contact / separation is possible (relatively displaceable). Thereby, the latching | locking part 11b is comprised so that switching to the state which latches the insertion part 11a and the state which cancels | releases the said latching is carried out.

また、掛止部１１ｂの幅寸法は、碍子６の取付孔６１の内幅寸法よりも大きく形成される。これにより、掛止部１１ｂが差入部１１ａを掛止する状態において、差入部１１ａが碍子６に対して相対的に変位した場合でも、掛止部１１ｂが碍子６の本体部６２を係止することにより、差入部１１ａが取付孔６１から抜け出るのを防止できる。   Moreover, the width dimension of the latching | locking part 11b is formed larger than the inner width dimension of the attachment hole 61 of the insulator 6. FIG. Thereby, even when the insertion portion 11a is displaced relative to the lever 6 in a state where the hook portion 11b hooks the insertion portion 11a, the hook portion 11b locks the main body portion 62 of the lever 6. Thus, it is possible to prevent the insertion portion 11a from coming out of the mounting hole 61.

支持体取付部１２は、環状（無端状）に構成される。そして、支持体取付部１２は、支持体７の取付孔７１に挿通可能に構成される。   The support attachment part 12 is configured in an annular shape (endless shape). And the support body attaching part 12 is comprised so that insertion to the attachment hole 71 of the support body 7 is possible.

なお、引込線支持具１は、一本の金属線から形成され、金属線の一端部側で差入部１１ａを構成し、金属線の他端部側で掛止部１１ｂを構成する。そして、引込線支持具１は、中間部で金属線を交差させることにより、一方側に環状（無端状）の碍子取付部１１ａを配置し、他方側に環状（無端状）の支持体取付部１１ｂを配置している。   The lead-in wire support 1 is formed of a single metal wire, and constitutes an insertion portion 11a on one end side of the metal wire, and constitutes a latching portion 11b on the other end side of the metal wire. And the lead-in wire support 1 arrange | positions the cyclic | annular (endless shape) insulator attachment part 11a on one side by making a metal wire cross | intersect in an intermediate part, and the cyclic | annular (endless shape) support body attachment part 11b on the other side. Is arranged.

本実施形態に係る引込線支持具１の構成については以上の通りであり、次に、本実施形態に係る引込線支持具１の取り付け方法について図４〜図６を参酌して説明する。なお、図４〜図６においては、引込線５を図示していないが、以下、引込線５が碍子６に固定されているものとして説明する。   The configuration of the lead-in wire support 1 according to the present embodiment is as described above. Next, a method for attaching the lead-in wire support 1 according to the present embodiment will be described with reference to FIGS. 4 to 6, the lead-in wire 5 is not illustrated, but the following description will be made assuming that the lead-in wire 5 is fixed to the insulator 6.

まず、差入部１１ａ又は掛止部１１ｂを支持体７の取付孔７１に差し入れ、引込線支持具１を支持体７に対して相対的に変位する。そうすると、図４に示すように、環状の支持体取付部１２が支持体７の取付孔７１に挿通した状態となるため、支持体取付部１２が支持体７を掛止可能な状態となる。このとき、掛止部１１ｂは、差入部１１ａを掛止しておらず、離間して配置されている。   First, the insertion part 11 a or the latching part 11 b is inserted into the mounting hole 71 of the support 7, and the lead-in wire support 1 is displaced relative to the support 7. Then, as shown in FIG. 4, since the annular support body attachment portion 12 is inserted into the attachment hole 71 of the support body 7, the support body attachment portion 12 is in a state in which the support body 7 can be hooked. At this time, the latching part 11b does not latch the insertion part 11a, but is spaced apart.

次に、引込線支持具１を碍子６に対して相対的に変位させ、図５に示すように、差入部１１ａを先端側から碍子６の取付孔６１に差し入れる。そして、差入部１１ａを碍子６の取付孔６１に挿通させ、差入部１１ａの先端側を碍子６の取付孔６１から突出（臨出）させる。   Next, the lead-in wire support 1 is displaced relative to the insulator 6, and the insertion portion 11a is inserted into the attachment hole 61 of the insulator 6 from the distal end side as shown in FIG. And the insertion part 11a is inserted in the attachment hole 61 of the insulator 6, and the front end side of the insertion part 11a is protruded (projects) from the attachment hole 61 of the insulator 6.

その後、図６に示すように、掛止部１１ｂが差入部１１ａの先端側を掛止するように、掛止部１１ｂを差入部１１ａに接近させる。そうすると、環状の碍子取付部１１が碍子６の取付孔６１に挿通した状態となるため、碍子取付部１１が碍子６を掛止可能な状態となる。このとき、引込線５が布設される方向（図６におけるＡ矢印方向）に碍子６が引っ張られるため、掛止部１１ｂが差入部１１ａをさらに強固に掛止することになる。   Then, as shown in FIG. 6, the latching part 11b is made to approach the insertion part 11a so that the latching part 11b latches the front end side of the insertion part 11a. If it does so, since it will be in the state which the cyclic | annular insulator attaching part 11 was penetrated to the attachment hole 61 of the insulator 6, the insulator attaching part 11 will be in the state which can latch the insulator 6. FIG. At this time, since the insulator 6 is pulled in the direction in which the lead-in wire 5 is laid (A arrow direction in FIG. 6), the latching portion 11b more firmly latches the insertion portion 11a.

以上より、本実施形態に係る引込線支持具１は、掛止部１１ｂが差入部１１ａに接離することにより、掛止部１１ｂが差入部１１ａを掛止する状態と、当該掛止を解除する状態とに切り替えることができるため、掛止部１１ｂが差入部１１ａの掛止を解除する状態で、差入部１１ａが碍子６の取付孔６１に先端側から差し入れられる。   As described above, the lead-in wire support 1 according to the present embodiment releases the latch and the state in which the latching part 11b latches the insertion part 11a when the latching part 11b contacts and separates from the insertion part 11a. Therefore, the insertion portion 11a is inserted into the attachment hole 61 of the lever 6 from the front end side in a state in which the engagement portion 11b releases the engagement of the insertion portion 11a.

そして、掛止部１１ｂが碍子６の取付孔６１から突出する差入部１１ａの先端側を掛止することにより、差入部１１ａが碍子６の取付孔６１から抜け出るのを防止できる。したがって、引込線５が碍子６に固定された状態においても、碍子６と支持体７とに容易に取り付けることができる。   And the latching | locking part 11b can prevent that the insertion part 11a slips out from the attachment hole 61 of the insulator 6 by latching the front end side of the insertion part 11a which protrudes from the attachment hole 61 of the insulator 6. FIG. Therefore, even when the lead-in wire 5 is fixed to the insulator 6, it can be easily attached to the insulator 6 and the support body 7.

また、本実施形態に係る引込線支持具１は、一本の金属線から形成され、金属線の一端部側で差入部１１ａが構成されると共に、金属線の他端部側で掛止部１１ｂが構成されているため、構成が簡易であり、製作コストを低減することもできる。   In addition, the lead-in wire support 1 according to the present embodiment is formed of a single metal wire, the insertion portion 11a is configured on one end portion side of the metal wire, and the latching portion 11b on the other end portion side of the metal wire. Therefore, the configuration is simple and the manufacturing cost can be reduced.

なお、本発明に係る引込支持具は、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。また、下記する各種の変更例に係る構成や方法等を任意に選択して、上記した実施形態に係る構成や方法等に採用してもよいことは勿論である。   It should be noted that the retractable support according to the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. Moreover, it is needless to say that configurations, methods, and the like according to various modifications described below may be arbitrarily selected and employed in the configurations, methods, and the like according to the above-described embodiments.

例えば、上記実施形態に係る引込線支持具１においては、碍子取付部１１の差入部１１ａの先端部が円弧状に沿ってフック状に形成される場合を説明したが、斯かる場合に限られない。例えば、図７に示すように、引込線支持具２の碍子取付部２１は、円弧状に形成される差入部２１ａを備え、差入部２１ａは、先端部が円弧状に形成される面と直交する方向（横方向）に屈曲して形成される場合でもよい。   For example, in the lead-in wire support 1 according to the above-described embodiment, the case where the distal end portion of the insertion portion 11a of the lever attachment portion 11 is formed in a hook shape along the arc shape has been described, but the present invention is not limited to such a case. .

For example, as shown in FIG. 8, the lead-in wire support 3 may be a case where the insertion portion 32 a and the latching portion 32 b are provided in the support attachment portion 32.

具体的には、引込線支持具３は、碍子６に取り付けられる碍子取付部３１と、支持体７に取り付けられる支持体取付部３２とを備え、支持体取付部３２は、支持体７の取付孔７１に先端側から差し入れられる差入部３２ａと、差入部３２ａが支持体７の取付孔７１から抜け出るのを防止すべく、取付孔７１から突出する差入部３２ａの先端側を掛止する掛止部３２ｂとを備える。   Specifically, the lead-in wire support 3 includes an insulator attachment portion 31 attached to the insulator 6 and a support attachment portion 32 attached to the support 7. The support attachment portion 32 is an attachment hole of the support 7. The insertion portion 32a to be inserted into the 71 from the distal end side, and the latching portion for latching the distal end side of the insertion portion 32a protruding from the attachment hole 71 in order to prevent the insertion portion 32a from coming out of the attachment hole 71 of the support 7 32b.

さらに、例えば、図９に示すように、引込線支持具４は、碍子６に取り付けられる碍子取付部４１と、支持体７に取り付けられる支持体取付部４２とを備え、碍子取付部４１は、碍子６の取付孔６１に先端側から差し入れられる差入部４１ａと、碍子６の取付孔６１から突出する差入部６１ａの先端側を掛止する掛止部６１ｂとを備え、支持体取付部４２は、支持体７の取付孔７１に先端側から差し入れられる差入部４２ａと、支持体７の取付孔７１から突出する差入部４２ａの先端側を掛止する掛止部４２ｂとを備える場合でもよい。   Further, for example, as shown in FIG. 9, the lead-in wire support 4 includes an insulator attachment portion 41 attached to the insulator 6 and a support attachment portion 42 attached to the support body 7, and the insulator attachment portion 41 is an insulator. 6 is provided with an insertion portion 41a inserted into the attachment hole 61 from the distal end side, and a latching portion 61b for latching the distal end side of the insertion portion 61a protruding from the attachment hole 61 of the insulator 6. It may be provided with the insertion part 42a inserted in the attachment hole 71 of the support body 7 from the front end side, and the latching part 42b which latches the front end side of the insertion part 42a which protrudes from the attachment hole 71 of the support body 7.

また、上記実施形態に係る引込線支持具１は、一本の金属線で形成される場合を説明したが、斯かる場合に限られない。例えば、引込線支持具は、複数の金属線で形成される場合でもよく、また、他の形状の金属材で形成される場合でもよい。要するに、本発明に係る引込線支持具は、材料やその数量に限定されることはない。   Moreover, although the lead wire support tool 1 which concerns on the said embodiment demonstrated the case where it formed with one metal wire, it is not restricted to such a case. For example, the lead-in wire support may be formed of a plurality of metal wires, or may be formed of a metal material having another shape. In short, the lead-in wire support according to the present invention is not limited to the material and the quantity thereof.
