本考案は、合成樹脂製のガス管や水道管等の管路の途中に溶着接合される分岐 溶着継手に用いられる加熱マットに関する。 This invention is a branch that is welded and joined in the middle of synthetic resin gas pipes, water pipes, etc. This invention relates to a heating mat used for welded joints.
【０００２】0002
従来、分岐溶着継手に用いられる加熱マットとしては、例えば、特開昭５８− ６５６２４号公報に記載されているようなものが知られている。 Conventionally, heating mats used for branch welding joints include, for example, The one described in Japanese Patent No. 65624 is known.
【０００３】 この従来の加熱マットは、樹脂シートの片面に形成された渦巻溝の内部に導電 線が挿着され、該導電線の一端が渦巻溝の内側端から渦巻溝を横断して渦巻溝の 外側に引き出されたものであった。0003 This traditional heating mat has a conductive inside spiral grooves formed on one side of the resin sheet. A wire is inserted, and one end of the conductive wire crosses the spiral groove from the inner end of the spiral groove. It was brought out to the outside.
【０００４】0004
しかしながら、このような従来の加熱マットにあっては、導電線の一端が渦巻 溝を横断しているために、渦巻溝内の導電線が溝から外れてとび出したりすると 、そのとび出した部分が渦巻溝を横断する導電線の一端部と接触して通電時に短 絡を起こす場合がある。そして、導電線が短絡を生じるとその周辺の樹脂が過度 に過熱されるため、分岐溶着継手に使用した場合、溶着不良発生の原因になる。 尚、渦巻溝を深くして渦巻溝内の導電線と渦巻溝を横断する導電線の端部との距 離をかせぐという手段も考えられるが、そうすると、樹脂シートを厚くする必要 があるためにコスト面で不利であると共に、分岐溶着継手の成形時に過熱マット をコアに沿わせて曲げる等の作業が行ない難い。また、渦巻溝を深くすると導電 線を挿入する作業も困難になるという問題が生じる。 However, in such conventional heating mats, one end of the conductive wire is swirled. If the conductive wire inside the spiral groove comes off the groove and sticks out because it crosses the groove. , the protruding part contacts one end of the conductive wire that crosses the spiral groove, causing a short circuit when energized. It may cause a collision. When a short circuit occurs in a conductive wire, the resin around it becomes excessively When used in branch welded joints, it can cause welding failure. In addition, by deepening the spiral groove, the distance between the conductive wire inside the spiral groove and the end of the conductive wire crossing the spiral groove can be increased. One possibility is to increase the distance, but then it would be necessary to make the resin sheet thicker. In addition to being disadvantageous in terms of cost due to It is difficult to perform tasks such as bending the material along the core. In addition, if the spiral groove is deep, it will become conductive. A problem arises in that the work of inserting lines becomes difficult.
【０００５】 本考案は、上記従来の問題に着目し、渦巻溝内の導電線と渦巻溝を横断する導 電線の端部との間で短絡が生じない加熱マットを提供することを目的としている 。[0005] The present invention focuses on the above-mentioned conventional problem, and the present invention focuses on the conductive wire inside the spiral groove and the conductor that crosses the spiral groove. The purpose is to provide a heating mat that does not cause short circuits with the ends of electric wires. .

上記目的を達成するために、本考案の加熱マットでは、分岐溶着継手に埋設さ れる加熱マットであって、熱可塑性樹脂を素材とした樹脂シートの片面に渦巻溝 が形成され、該渦巻溝の内部に加熱要素としての導電線が挿着され、該導電線の 一端部が渦巻溝の内側端から渦巻溝を横断して渦巻溝の外側に引き出されている 加熱マットにおいて、前記樹脂シートに、前記渦巻溝を横断する導電線の端部を 支持する絶縁性突起を設けた構成とした。 In order to achieve the above purpose, the heating mat of the present invention has a It is a heating mat with spiral grooves on one side of a resin sheet made of thermoplastic resin. is formed, a conductive wire as a heating element is inserted inside the spiral groove, and the conductive wire is heated. One end is pulled out from the inner end of the spiral groove, across the spiral groove, and to the outside of the spiral groove. In the heating mat, the ends of the conductive wires that cross the spiral grooves are attached to the resin sheet. The structure includes an insulating protrusion for support.
【０００７】[0007]
本考案の加熱マットでは、樹脂シートに、渦巻溝を横断する導電線の端部を支 持する絶縁性突起が設けられているので、渦巻溝内の導電線が渦巻溝からとび出 たとしても、そのとび出した部分と渦巻溝を横断する導電線の一端部は絶縁性突 起によって離間されているので絶縁状態が維持される。 In the heating mat of this invention, the end of the conductive wire that crosses the spiral groove is supported on the resin sheet. Since the insulating protrusion is provided to hold the conductive wire inside the spiral groove, it will not protrude from the spiral groove. Even if the protruding part and one end of the conductive wire that crosses the spiral groove are insulating protrusions, The insulation state is maintained because they are separated by the spring.

One end is connected to the terminal pin 15 from the outer end of the spiral groove 12. The other end extends from the inner end of the spiral groove 12 across the spiral groove 12 to the outside of the spiral groove 12. It is pulled out and connected to the terminal pin 16. In addition, the conductive wire 2 is made of iron black. General resistance wire materials such as aluminum, nichrome, chromel, copper nickel, copper manganese nickel, etc. can be used. The wire diameter of the conductive wire 2 is 0.3 to 1.5 mm. In that case, the spiral grooves 12 formed in the resin sheet 1 have a depth that is conductive. 1.2 to 3 times the wire diameter of wire 2, and the width is about 0.01 to 0.03 mm than the wire diameter of conductive wire 2. It is preferable to widen the range.
【００１１】 更に、前記導電線２が樹脂シート１の渦巻溝１２からとび出さないようにする ために導電線２を渦巻溝１２内に挿入した後、渦巻溝１２の上からヒータを当て る等して樹脂シート１の表面を少しだけ溶融し、導電線２と樹脂シート１を溶着 してもよい。尚、樹脂シート１を溶融する手段としては、ヒーターの他に、高周 波や超音波を使用することもできる。[0011] Furthermore, the conductive wire 2 is prevented from protruding from the spiral groove 12 of the resin sheet 1. After inserting the conductive wire 2 into the spiral groove 12, a heater is applied from above the spiral groove 12. Melt the surface of the resin sheet 1 a little by melting, etc., and weld the conductive wire 2 and the resin sheet 1. You may. In addition, as a means for melting the resin sheet 1, in addition to a heater, a high frequency Waves or ultrasound can also be used.
【００１２】 絶縁性突起３は、樹脂シート１の渦巻溝１２の上に形成されており、渦巻溝１ ２を横断する導電線２の端部を支持している。この絶縁性突起３は、導電線２を 渦巻溝１２に装着した後であり、かつ、導電線２の端部をターミナルピン１５， １６に接続するより前に渦巻溝１２の上に形成する。尚、絶縁性突起３に導電線 ２の端部を支持させる場合には、絶縁性突起３が完全に固化する前に絶縁性突起 ３の上に導電線２を載せるようにし、その際、導電線２に張力を与え、導電線２ が絶縁性突起３の上部に少し食い込むようにする。0012 The insulating protrusion 3 is formed on the spiral groove 12 of the resin sheet 1. The end of the conductive wire 2 that crosses the conductive wire 2 is supported. This insulating protrusion 3 connects the conductive wire 2. This is after the conductive wire 2 is attached to the spiral groove 12, and the end of the conductive wire 2 is connected to the terminal pin 15, It is formed on the spiral groove 12 before connecting to the spiral groove 16. In addition, there is a conductive wire on the insulating protrusion 3. If the end of the insulating protrusion 3 is to be supported, the insulating protrusion 3 must be completely solidified. The conductive wire 2 is placed on top of the conductive wire 2, and at that time, tension is applied to the conductive wire 2, and the conductive wire 2 so that it bites into the upper part of the insulating protrusion 3 a little.
【００１３】 また、絶縁性突起３は、加熱装置によって溶融させた熱可塑性樹脂を押出し機 （例えば、ノズル径１ｍｍ、押出量１〜２０ｋｇ／ｈ）で樹脂シート１上に落し て形成されている。この場合、溶融させる樹脂として樹脂シート１を射出成形し た時に残る中空ゲートを使用すると経済的である。尚、絶縁性突起３の材料は合 成樹脂であればよいが、樹脂シート１と同色の同材料が好ましい。[0013] In addition, the insulating protrusion 3 is made by extruding thermoplastic resin melted by a heating device. (for example, nozzle diameter 1 mm, extrusion rate 1 to 20 kg/h) onto the resin sheet 1. It is formed by In this case, the resin sheet 1 is injection molded as the resin to be melted. It is economical to use a hollow gate that remains when the In addition, the material of the insulating protrusion 3 is Any synthetic resin may be used, but the same material with the same color as the resin sheet 1 is preferable.
【００１４】 また、絶縁性突起３の位置は、樹脂シート１の孔１１からの距離Ｌ１が、渦巻 部３０の幅Ｌの０．２倍から０．５倍の範囲（０．２Ｌ≦Ｌ１≦０．５Ｌ）内に なるように設定されている。[0014] Further, the position of the insulating protrusion 3 is such that the distance L1 from the hole 11 of the resin sheet 1 is Within the range of 0.2 to 0.5 times the width L of the portion 30 (0.2L≦L1≦0.5L) It is set to be.
【００１５】 以上説明したように本実施例の加熱マットでは、樹脂シート１の渦巻溝１２を 横断する導電線２の端部を、樹脂シート１に形成した絶縁性突起３に支持させて いるので、渦巻溝１２内の導電線２が渦巻溝１２からとび出たとしても、そのと び出した部分と渦巻溝１２を横断する導電線２の一端部は絶縁性突起３によって 離間されているので絶縁状態が維持される。従って、通電時に渦巻溝１２内の導 電線２と渦巻溝１２を横断する導電線２の端部との間で短絡が生じるのを防止す ることができる。[0015] As explained above, in the heating mat of this embodiment, the spiral grooves 12 of the resin sheet 1 are The ends of the conductive wires 2 that cross are supported by insulating protrusions 3 formed on the resin sheet 1. Therefore, even if the conductive wire 2 inside the spiral groove 12 protrudes from the spiral groove 12, the One end of the conductive wire 2 that crosses the protruding portion and the spiral groove 12 is connected by an insulating protrusion 3. Since they are spaced apart, an insulated state is maintained. Therefore, the conduction inside the spiral groove 12 when energized To prevent a short circuit from occurring between the electric wire 2 and the end of the conductive wire 2 that crosses the spiral groove 12. can be done.
【００１６】 図５は、溶着分岐サドルを示した断面図で、加熱マットＭはこの溶着分岐継手 Ｓのサドル部１０の内周部に埋設して使用するものである。従って、加熱マット Ｍに使用する絶縁性突起３の高さＨは、絶縁性を確保するために２ｍｍ以上とし 、かつ絶縁性突起３が製品の表面に現れないようにするためにできるだけサドル 部１０の肉厚Ｔの０．９倍以下に設定する。また、絶縁性突起３ａの外径Ｄは渦 巻溝１２の幅Ｌの０．３倍またはそれ以下（Ｄ≦０．３Ｌ）に設定することが好 ましい。それは、絶縁性突起３の外径Ｄが大きすぎると、樹脂シート１を溶着分 岐サドルＳのサドル部１０の内周に沿って湾曲させる際に、この絶縁性突起３の 部分だけが平たくなってしまうからである。[0016] Figure 5 is a sectional view showing the welded branch saddle, and the heating mat M is attached to this welded branch joint. It is used by being embedded in the inner peripheral part of the saddle part 10 of the S. Therefore, the heating mat The height H of the insulating protrusion 3 used for M should be 2 mm or more to ensure insulation. , and the saddle as much as possible to prevent the insulating protrusion 3 from appearing on the surface of the product. The thickness is set to 0.9 times or less of the wall thickness T of the portion 10. In addition, the outer diameter D of the insulating protrusion 3a is It is preferable to set it to 0.3 times the width L of the winding groove 12 or less (D≦0.3L). Delicious. If the outer diameter D of the insulating protrusion 3 is too large, the resin sheet 1 will be welded. When bending the saddle portion 10 of the branched saddle S along the inner circumference, the insulating protrusion 3 This is because only the part becomes flat.
【００１７】 以上、本考案の実施例を図面により詳述してきたが、具体的な構成はこの実施 例に限られるものではなく、本考案の要旨を逸脱しない範囲における設計の変更 等があっても本考案に含まれる。例えば、実施例では樹脂シートの形状を方形状 にしたが、円形や楕円形、多角形等にしてもよい。また、絶縁性突起の平面形状 は円形状に限らず、楕円形状等にしてもよい。更に、加熱マットは、溶着分岐サ ドル以外に、例えば溶着分岐サービスチー等に使用することができる。[0017] Above, the embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is as follows. This is not limited to examples, and changes in design within the scope of the gist of the present invention. Even if there is such a thing, it is included in this invention. For example, in the example, the shape of the resin sheet is rectangular. However, it may also be circular, oval, polygonal, etc. In addition, the planar shape of the insulating protrusion is not limited to a circular shape, but may be an elliptical shape or the like. Additionally, the heating mat has a welding branch service. In addition to dollars, it can be used, for example, for welding branch service chips.
