Description

【0001】
【発明の属する技術分野】
本発明は、平形電線を住宅等に施設する時に電線の外観から、極性の判別を必要とする配線場所に有効な識別電線に関するものである。
【0002】
【従来の技術】
布設場所で極性の判別が必要な所にはシース外観にインクで印を入れておくか、識別項目を記入したラベルを張付ける方法がある。(例えば特開平10−172362)
【0003】
【発明が解決しようとする課題】
平形電線を施設していて、支持しなければならない所では丸型電線と異なり、長径部分を造営材と平行にするように考慮しながらサドルやステップルで堅ろうに固定しなければならない。
ほとんどの露出配線の場合、開閉器やしゃ断器を設けるキャビネットや電動機等の制御回路を設けるボックスの入口付近での配線は支持を数ヶ所設けて平形電線を引き込む事になる。
【0004】
機器までの距離が予め分かっていれば、先に電線を切断しておき断面を見て絶縁体心の配列から極性を確認しながら平形電線を捻れないように支持して行けるが、ほとんどの場合接続しようとする機器に向かって電線を1ヶ所ずつ支持しながら配電・配線ボックスに近づいて行き、電線の長さがある程度分かってから切断するのが常である。
この方法で有ると、特に線心数の多い平形電線を支持して行き機器に接続する時になって絶縁体を捻る事になる場合が出てくる。
また露出配線、いんぺい配線にかかわらず電線をキャビネットやボックス内に引き込んでからは支持具で接続機器まで数ヶ所止めて配線回路を組み立てている。
【0005】
本発明は、予め電線表面から極性が分かっていると、キャビネットやボックスの前後で捻れを起こさずに配線が行える。
また電線を施設後極性を識別する必要が生じた場合容易に目的の絶縁体位置が、シース表面から確定できる事を提供することができる。
【0006】
【課題を解決するための手段】
600Vビニル絶縁ビニルシースケーブル平形(VVF)の表面に、絶縁体色と同色のラインを電線軸に沿って入れた平形電線を製作する。
ラインが電線の長径の端にかかる所は、円弧状とし電線両面から判別できるようにする。
【0007】
【作用】
VVFケーブルの表面に絶縁体識別用のラインを入れる事により、配線時に各極性が予め分かるため支持具を取り付ける際に接続機器への配線方向を考慮し捻れを起こさずに布設でき、また後に絶縁体の極性を識別する必要が生じた時にシース上から極性が容易に分かる点が有る。
【0008】
【発明の実施の形態】
絶縁体心線2本(黒・白)上に色識別のライン入りシースを被覆させる場合には電線用主押出機1台と副押出機1台を使用して製造する事ができる。
図1の様な電線被覆設備を使用して、予め黒色ラインを被覆できるように加工されたダイス9を装着した主押出機1に黒色樹脂が入った副押出機3を図3のライン用の注入口8に接続し、主押出機1にて主要部分14白色を被覆し同時に副押出機3にて識別用黒色ライン部分13を被覆すると2心の色識別平形電線(図4)を得る事ができる。
【0009】
同様に3心(黒・白・赤)の場合も図1の様な電線被覆装置から副押出機2と3の2台を使用し主押出機1に2色用のライン用注入口を設けたダイスを装着して主押出機1で主要白色部分14を被覆し、副押出機3で黒色ライン部分13を被覆し、同様に副押出機3にて赤色ライン部分16を被覆する事により3心の色識別平形電線(図5)が得られる。
【発明の効果】
600Vビニル絶縁ビニルシースケーブル平形(VVF)のシース表面に絶縁体と平行に同色のラインを入れた事により、露出配線時やボックスの前後で支持する場合また施設後極性の識別する必要が生じた場合、外観から絶縁体の配置が分かる事から、シース上から絶縁体位置を容易に判別する事ができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an identification wire that is effective at a wiring place where the polarity needs to be determined from the appearance of the wire when installing a flat wire in a house or the like.
[0002]
[Prior art]
Where the polarity is required to be determined at the installation site, there is a method of marking the outer surface of the sheath with ink or attaching a label with an identification item. (For example, JP-A-10-172362)
[0003]
[Problems to be solved by the invention]
Where a flat wire is installed and must be supported, unlike a round wire, it must be fixed firmly with saddles and staples, taking into account that the long diameter part is parallel to the construction material.
In the case of most of the exposed wiring, the wiring near the entrance of the box in which the control circuit such as the cabinet or the electric motor is provided with the switch and the circuit breaker is provided with several supports and the flat electric wire is drawn in.
[0004]
If you know the distance to the device in advance, you can cut the wire first, check the cross section, check the polarity from the arrangement of the insulator cores, and support the flat wire so that it will not be twisted, but in most cases It is usual to approach the power distribution / wiring box while supporting the wires one by one toward the device to be connected, and cut the wires after the length of the wires is known to some extent.
According to this method, there is a case where the insulator is twisted when a flat wire having a large number of cores is supported and connected to a device.
Also, regardless of exposed wiring or impure wiring, wires are drawn into cabinets and boxes, and then fixed at several places to connected devices with supports to assemble the wiring circuit.
[0005]
According to the present invention, if the polarity is known in advance from the surface of the electric wire, wiring can be performed without twisting around the cabinet or box.
In addition, it is possible to provide that the target insulator position can be easily determined from the sheath surface when it is necessary to identify the polarity after the installation of the electric wire.
[0006]
[Means for Solving the Problems]
A flat electric wire in which a line of the same color as the insulator color is inserted along the electric wire axis on the surface of a 600 V vinyl insulated vinyl sheath cable flat type (VVF).
Where the line extends to the end of the major axis of the electric wire, it is formed in an arc shape so that it can be identified from both sides of the electric wire.
[0007]
[Action]
By inserting a line for identifying the insulator on the surface of the VVF cable, each polarity can be known in advance at the time of wiring, so that when mounting the support, the wiring direction to the connected device can be taken into consideration and the cable can be laid without twisting, and later insulated There is a point that the polarity can be easily recognized from the sheath when it is necessary to identify the polarity of the body.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
When two sheathed core wires (black and white) are covered with a sheath with a line for color identification, it can be manufactured using one main extruder and one sub-extruder for electric wires.
Using the electric wire coating equipment as shown in FIG. 1, a sub-extruder 3 containing black resin in a main extruder 1 equipped with a die 9 previously processed so as to be able to cover a black line is used for the line shown in FIG. When the main extruder 1 is connected to the inlet 8 and the main part 14 is covered with white and the sub-extruder 3 is covered with the identification black line part 13, a two-core color-identifying flat wire (FIG. 4) is obtained. Can be.
[0009]
Similarly, in the case of three cores (black, white and red), two auxiliary extruders 2 and 3 are used from the electric wire covering device as shown in FIG. The main extruder 1 covers the main white portion 14, the sub-extruder 3 covers the black line portion 13, and the sub-extruder 3 covers the red line portion 16 in the same manner. A heart-color-identifying flat wire (FIG. 5) is obtained.
【The invention's effect】
600V vinyl insulated vinyl sheathed cable Flat type (VVF) sheath line with the same color line parallel to the insulator to support at the time of exposed wiring, before and after the box, and when it is necessary to identify the polarity after the facility Since the arrangement of the insulator can be known from the appearance, the position of the insulator can be easily determined from the sheath.
