Description
本發明係有關在150℃以上的高溫環境下使用的耐熱帶型電纜及其製造方法以及耐熱線束。 The present invention relates to a heat-resistant ribbon type cable used in a high-temperature environment of 150 ° C or higher, a method for manufacturing the same, and a heat-resistant wire harness.
如第3圖所示，作為在150℃以上的高溫環境下(例如內燃機的周邊配線)使用的耐熱帶型電纜30，習知為具有並列的多根電線31及被覆層32的耐熱帶型電纜，該被覆層32被一體地擠出被覆在多根電線31的周圍並且由具有150℃以上耐熱性的氟樹脂構成(參照專利文獻1)。 As shown in FIG. 3, the heat-resistant ribbon type cable 30 used in a high-temperature environment of 150 ° C or higher (for example, peripheral wiring of an internal combustion engine) is known as a heat-resistant ribbon cable having a plurality of electric wires 31 and a coating layer 32 in parallel. The coating layer 32 is integrally extruded around the plurality of electric wires 31 and is made of a fluororesin having heat resistance of 150° C. or higher (see Patent Document 1).
然而，在這樣結構的耐熱帶型電纜30中，有以下問題之虞：在分支型的終端配線加工時即使想要僅將被覆層32撕開剝下，電線31的絕緣層33也會與被覆層32一起裂開，使電線31的導體34露出而引起電氣短路、絕緣不良等問題。 However, in the heat-resistant ribbon type cable 30 having such a configuration, there is a problem that even if it is desired to peel only the covering layer 32 at the time of branch-type terminal wiring processing, the insulating layer 33 of the electric wire 31 is covered and covered. The layer 32 is split together to expose the conductor 34 of the electric wire 31 to cause problems such as electrical short circuit and poor insulation.
另外，由於被覆層32被一體地擠出被覆在多根電線31的周圍，作為電纜整體，可撓性差而難以彎曲，因此，在彎曲時有被覆層32、絕緣層33容易裂開且耐彎曲性差這樣的問題、配線自由度降低這樣的問題。 In addition, since the covering layer 32 is integrally extruded around the plurality of electric wires 31, the flexibility of the entire cable is poor and it is difficult to bend. Therefore, the covering layer 32 and the insulating layer 33 are easily cracked and resistant to bending during bending. Problems such as poor performance and problems such as reduced degree of freedom in wiring.
進一步，如上所述，由於無法進行分支型的終端配線加工，能夠與終端連接的連接器被限制為壓接連接器，因此，還有終端配線加工性差這樣的問題。 Further, as described above, since the branch type terminal wiring processing cannot be performed, the connector that can be connected to the terminal is limited to the crimp connector, and therefore there is a problem that the terminal wiring workability is poor.
對此，已知一種耐熱帶型電纜，其具有並列的多根電線及對多根電線不會變形而織入到每規定根數中之柔軟的纖絲(例如參照專利文獻2)。 On the other hand, a heat-resistant ribbon type cable having a plurality of parallel electric wires and a flexible filament which is woven into a predetermined number without deforming the plurality of electric wires is known (for example, see Patent Document 2).
通過這樣使用柔軟的纖絲例如具有伸縮性的聚酯纖維，從而與將被覆層一體地擠出被覆在多根電線的周圍的情況相比，電纜整體的可撓性提高。 By using a soft filament such as a stretchable polyester fiber in this manner, the flexibility of the entire cable is improved as compared with the case where the coating layer is integrally extruded around the plurality of electric wires.

專利文獻2：日本特開2001-101934號公報 Patent Document 2: Japanese Laid-Open Patent Publication No. 2001-101934
然而，由於聚酯纖維的推薦額定溫度約為80℃，因此，擔心有在上述的高溫環境下不能連續地捆紮多根電線，產生由於承受反復彎曲而容易引起電線彼此的牽連及其所伴隨斷線的問題。 However, since the recommended rated temperature of the polyester fiber is about 80 ° C, there is a fear that the plurality of electric wires cannot be continuously bundled in the above-mentioned high temperature environment, and it is easy to cause the electric wires to be implicated and their accompanying due to repeated bending. Line problem.
為了解決該問題，雖然考慮使纖絲的材質為具有優異的耐熱性的氟樹脂纖維，但由於氟樹脂纖維與聚酯纖維相比柔軟性差，因此，可能會在捆紮的多根電線上產生彎曲半徑小的彎曲，由於承受反復彎曲而產生斷線、或者降低電纜整體的可撓性從而使耐彎曲性降低。 In order to solve this problem, it is considered that the material of the filament is a fluororesin fiber having excellent heat resistance. However, since the fluororesin fiber is inferior in flexibility to the polyester fiber, bending may occur on the bundled plurality of wires. The bending with a small radius causes the wire to be broken due to repeated bending, or the flexibility of the entire cable is lowered to lower the bending resistance.
因此，本發明的目的在於提供一種儘管使用氟樹脂纖維作為纖絲的材質但其耐彎曲性也很優異的耐熱帶型電纜及其製造方法以及耐熱線束。 Accordingly, an object of the present invention is to provide a heat-resistant ribbon type cable which is excellent in bending resistance despite the use of a fluororesin fiber as a material of a filament, a method for producing the same, and a heat-resistant wire harness.

下面，基於附圖說明本發明的優選實施方式。 Hereinafter, preferred embodiments of the present invention will be described based on the drawings.
如第1圖(a)及第1圖(b)所示，本實施方式有關的耐熱帶型電纜10的特徵在於，具有並列的多根電線11及在多根電線11中織入的纖絲12，纖絲12是對具有150℃以上耐熱性的多根氟樹脂纖維進行假撚加工而形成。 As shown in Fig. 1 (a) and Fig. 1 (b), the heat-resistant ribbon cable 10 according to the present embodiment is characterized in that it has a plurality of electric wires 11 juxtaposed and filaments woven into the plurality of electric wires 11 12. The filament 12 is formed by subjecting a plurality of fluororesin fibers having heat resistance of 150 ° C or higher to false twist processing.
多根電線11具有導體13及在導體13的周圍形成的絕緣層14，絕緣層14可以使用任意材料。例如，在對耐熱帶型電纜10具有細徑化要求的情況下可以使用氟樹脂，具體地說，可以從四氟乙烯-乙烯共聚物(ETFE)、四 氟乙烯-六氟丙烯共聚物(FEP)、四氟乙烯-全氟烷基乙烯基醚共聚物(PFA)或者聚四氟乙烯(PTFE)中之任一種或者二種以上的組合中選擇。由於這些氟樹脂的介電常數低至2.1至2.6，且可以使絕緣層14的厚度變薄，因此可以使耐熱帶型電纜10細徑化。另外，在對耐熱帶型電纜10具有柔軟性要求的情況下，可以從聚乙烯(PE)、聚丙烯(PP)等聚烯烴系樹脂、聚氯乙烯(PVC)系樹脂、聚胺酯(PU)系樹脂、該等的交聯樹脂或者該等的發泡樹脂中之任一種或者二種以上的組合中選擇。這些樹脂雖然柔軟性良好而耐熱性、阻燃性差，但是通過織入後述的氟樹脂纖維來覆蓋表面，可以在保持柔軟性的狀態下對耐熱帶型電纜10賦予耐熱性、阻燃性。另外，進一步，聚氯乙烯樹脂、聚胺酯樹脂雖然耐摩擦性、耐磨耗性差，但通過織入後述的氟樹脂纖維來覆蓋表面，可以在保持柔軟性的狀態下對耐熱帶型電纜10賦予耐摩擦性、耐磨耗性，即使在狹小部分進行配線的情況，也不用擔心絕緣層14產生擦傷、刮傷等。 The plurality of electric wires 11 have a conductor 13 and an insulating layer 14 formed around the conductor 13, and any material can be used for the insulating layer 14. For example, a fluororesin may be used in the case where the heat-resistant ribbon type cable 10 has a thinning requirement, specifically, a tetrafluoroethylene-ethylene copolymer (ETFE), four Any one or a combination of two or more of a vinyl fluoride-hexafluoropropylene copolymer (FEP), a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA), or a polytetrafluoroethylene (PTFE). Since the dielectric constant of these fluororesins is as low as 2.1 to 2.6, and the thickness of the insulating layer 14 can be made thin, the heat-resistant ribbon type cable 10 can be made thinner. In addition, when the heat-resistant tape type cable 10 has flexibility requirements, it can be made of a polyolefin resin such as polyethylene (PE) or polypropylene (PP), a polyvinyl chloride (PVC) resin, or a polyurethane (PU) system. Any one or a combination of two or more of a resin, such a crosslinked resin or the above-mentioned foamed resins is selected. Although these resins are excellent in flexibility and are inferior in heat resistance and flame retardancy, by covering the surface with a fluororesin fiber to be described later, heat resistance and flame retardancy can be imparted to the heat-resistant ribbon cable 10 while maintaining flexibility. In addition, the polyvinyl chloride resin and the polyurethane resin are inferior in abrasion resistance and abrasion resistance. However, by covering the surface with a fluororesin fiber to be described later, the heat-resistant ribbon cable 10 can be provided with resistance while maintaining flexibility. Friction and wear resistance, even in the case where wiring is performed in a narrow portion, there is no fear of scratching, scratching, or the like of the insulating layer 14.
另外，多根電線11可以在絕緣層14的外周進一步具有遮罩層及其外周的護套，護套可以與絕緣層14同樣地根據目的使用任意材料。 Further, the plurality of electric wires 11 may further have a sheath layer and a sheath of the outer periphery thereof on the outer circumference of the insulating layer 14, and the sheath may be any material used depending on the purpose, similarly to the insulating layer 14.
另外，上述的交聯樹脂可以使用通過化學交聯、電子束交聯等一般的交聯法製造的樹脂，上述的發泡樹脂可以使用通過化學發泡、物理發泡等一般的發泡法而製造的樹脂。 Further, as the above-mentioned crosslinking resin, a resin produced by a general crosslinking method such as chemical crosslinking or electron beam crosslinking can be used, and the above-mentioned foaming resin can be used by a general foaming method such as chemical foaming or physical foaming. Manufactured resin.
纖絲12如上所述是對具有150℃以上耐熱性的多根氟樹脂纖維進行假撚加工而形成的多彈性纖維。這裡，所謂的假撚加工，其代表性的是通過順向加撚纖維，將加撚後的纖維加熱而固定形狀，最後逆向加撚纖維而解撚，從而對纖維賦予伸縮性(柔軟性)、捲縮性的加工方法。 As described above, the filament 12 is a multi-elastic fiber formed by subjecting a plurality of fluororesin fibers having heat resistance of 150 ° C or higher to false twist processing. Here, the so-called false twist processing is typically performed by heating the twisted fibers in a forward direction to fix the shape, and finally twisting the fibers in the reverse direction to release the fibers, thereby imparting stretchability (softness) to the fibers. , crimping processing methods.
多根氟樹脂纖維例如由四氟乙烯-全氟烷基乙烯基醚共聚物構成。四氟乙烯-全氟烷基乙烯基醚共聚物的耐熱性優異，具有150℃以上的耐熱性。 The plurality of fluororesin fibers are composed, for example, of a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer. The tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer is excellent in heat resistance and has heat resistance of 150 ° C or higher.
通過將該纖絲12織入多根電線11中，與僅將1根氟樹脂形成之纖維織入多根電線11中的情況相比，能夠降低纖絲12對電線11產生的局部應力。 By weaving the filaments 12 into the plurality of electric wires 11, the local stress generated by the filaments 12 on the electric wires 11 can be reduced as compared with the case where only the fibers formed of one fluororesin are woven into the plurality of electric wires 11.
具體地說，在將由1根氟樹脂纖維構成的纖絲織入多根電線11時，由於織入纖絲時的應力通過1根氟樹脂纖維作用在電線11上，因此，使該應力局部地集中作用在電線11的一部分。 Specifically, when the filaments composed of one fluororesin fiber are woven into the plurality of electric wires 11, the stress at the time of weaving the filaments acts on the electric wires 11 through one fluororesin fiber, so that the stress is locally made Concentrated on a part of the electric wire 11.
與此相對，在將由多根氟樹脂纖維構成的纖絲12織入多根電線11時，由於將纖絲12織入時的應力通過多根氟樹脂纖維作用在電線11上，因此，使該應力分散地作用在多根氟樹脂纖維的各自上。 On the other hand, when the filaments 12 composed of a plurality of fluororesin fibers are woven into the plurality of electric wires 11, the stress when the filaments 12 are woven is applied to the electric wires 11 through the plurality of fluororesin fibers. The stress acts discretely on each of the plurality of fluororesin fibers.
因此，能夠降低纖絲12對電線11產生的局部應力，在捆紮的多根電線11上不易產生彎曲半徑小的彎曲，耐熱帶型電纜10即使承受反復彎曲電線11也難以產生斷線。 Therefore, the local stress generated by the filaments 12 on the electric wires 11 can be reduced, and the bending of the plurality of bundled electric wires 11 is less likely to occur, and the heat-resistant ribbon cable 10 is less likely to be broken even if the electric wires 11 are repeatedly bent.
另外，由於纖絲12的伸縮性(柔軟性)、捲縮性優異，因此不會損害電纜整體的可撓性，即使對耐熱帶型電纜10承受反復彎曲的部分進行配線，電線11的斷線壽命與以往的耐熱帶型電纜30相比也更長。 In addition, since the filament 12 is excellent in stretchability (flexibility) and crimping property, the flexibility of the entire cable is not impaired, and even if the heat-resistant ribbon cable 10 is subjected to repeated bending, the wire 11 is broken. The life is longer than that of the conventional heat-resistant ribbon cable 30.
因此，根據耐熱帶型電纜10，儘管使用氟樹脂纖維作為纖絲12的材質，也能夠實現充分的耐彎曲性。 Therefore, according to the heat-resistant tape type cable 10, although the fluororesin fiber is used as the material of the filament 12, sufficient bending resistance can be achieved.
另外，纖絲12由於通過假撚加工將多根氟樹脂纖維各自分散開而織入電線11中，因此可以用氟樹脂纖維覆蓋電線11的表面，即使電線11的絕緣層14、護套使用了耐熱性低的樹脂，也不會損害電線11的柔軟性等特性，可以對電線11賦予耐熱性。 In addition, since the filaments 12 are woven into the electric wires 11 by dispersing a plurality of fluororesin fibers by false twisting, the surface of the electric wires 11 can be covered with the fluororesin fibers even if the insulating layer 14 and the sheath of the electric wires 11 are used. The resin having low heat resistance does not impair the properties such as flexibility of the electric wire 11, and heat resistance can be imparted to the electric wire 11.
進一步，基於同樣的理由，可以對電線11賦予阻燃性、耐摩擦性、及/或耐磨耗性。 Further, for the same reason, the electric wire 11 can be imparted with flame retardancy, abrasion resistance, and/or abrasion resistance.
另外，由於纖絲12可以在任意位置切斷而容易地解開，因此能夠在多根電線11各自為獨立的狀態下以不同的長度且由不同的終端配線加工而與各種連接器(例如PCB基板、FPC、MFJ)連接。 In addition, since the filament 12 can be easily cut at any position, it is possible to process various connectors (for example, PCB) with different lengths and different terminal wirings in a state in which the plurality of electric wires 11 are independent from each other. Substrate, FPC, MFJ) connection.
進一步，由於終端配線加工時不會對電線11的絕緣層14產生任何影響，因此，不用擔心如以往的耐熱帶型電纜30那樣，電線11的絕緣層14裂開而露出電線11的導體13，引起電氣短路、絕緣不良這樣的問題。 Further, since the terminal wiring is processed without any influence on the insulating layer 14 of the electric wire 11, there is no fear that the insulating layer 14 of the electric wire 11 is cracked to expose the conductor 13 of the electric wire 11 as in the conventional heat-resistant ribbon cable 30. Problems such as electrical short circuit and poor insulation.
另外，即使在將耐熱帶型電纜10用作內燃機的周邊配線的情況下，由於通過伸縮性(柔軟性)、捲縮性優異的纖絲12可以吸收施加在耐熱帶型電纜10上的振動，因此，無需為了實施用於防止由振動引起的疲勞斷裂等的振動對策而在耐熱帶型電纜10上設置其他構件、其他被覆，能夠實現耐熱帶型電纜10的小型化。 In addition, even when the heat-resistant ribbon type cable 10 is used as the peripheral wiring of the internal combustion engine, the vibration applied to the heat-resistant ribbon type cable 10 can be absorbed by the filament 12 excellent in stretchability (flexibility) and crimping property. Therefore, it is not necessary to provide other members and other coatings on the heat-resistant ribbon cable 10 in order to prevent vibration countermeasures such as fatigue fracture caused by vibration, and it is possible to reduce the size of the heat-resistant ribbon cable 10.
接著，對耐熱帶型電纜的製造方法進行說明。 Next, a method of manufacturing the heat-resistant belt type cable will be described.
本實施方式相關的耐熱帶型電纜的製造方法，其特徵在於，具有如下 步驟：對具有150℃以上耐熱性的多根氟樹脂纖維實施假撚加工而製作纖絲12的步驟、以及在並列的多根電線11中織入纖絲12的步驟。 A method of manufacturing a heat-resistant ribbon cable according to the present embodiment is characterized by having the following Step: a step of producing a fibril 12 by performing a false twisting process on a plurality of fluororesin fibers having a heat resistance of 150 ° C or higher, and a step of weaving the filaments 12 in a plurality of parallel electric wires 11 .
對於並列的多根電線11中織入纖絲12的步驟，一邊將捲縮的纖絲12伸長一邊在多根電線11中進行織入。由此，多根電線11被牢固地捆紮，能夠防止由於對耐熱帶型電纜10施加的振動等而使多根電線11解開、電線11彼此接觸、損傷電線11的絕緣層14。 The step of weaving the filaments 12 into the plurality of parallel electric wires 11 is performed by weaving the plurality of electric wires 11 while stretching the crimped filaments 12. Thereby, the plurality of electric wires 11 are firmly bundled, and it is possible to prevent the plurality of electric wires 11 from being unwound due to vibration or the like applied to the heat-resistant belt-type cable 10, and the electric wires 11 are in contact with each other, and the insulating layer 14 of the electric wires 11 is damaged.
接著對耐熱線束進行說明。 Next, the heat resistant wire harness will be described.
如第2圖所示，本實施方式有關的耐熱線束20的特徵在於，具有耐熱帶型電纜10及連接於耐熱帶型電纜10的終端的連接器21。連接器21例如連接於耐熱帶型電纜10的每個分支終端。 As shown in FIG. 2, the heat-resistant wire harness 20 according to the present embodiment is characterized in that it has a heat-resistant tape type cable 10 and a connector 21 connected to a terminal end of the heat-resistant tape type cable 10. The connector 21 is connected, for example, to each branch terminal of the heat-resistant ribbon type cable 10.
在該耐熱線束20中，由於可以將耐熱帶型電纜10的纖絲12在任意的位置切斷而容易地解開，因此能夠將連接器21連接於耐熱帶型電纜10的每個分支終端。也就是說，能夠根據配線狀況、配線佈局而實現各種形態的耐熱線束20。 In the heat-resistant wire harness 20, since the filament 12 of the heat-resistant ribbon cable 10 can be easily cut at an arbitrary position, the connector 21 can be connected to each branch terminal of the heat-resistant ribbon cable 10. In other words, the heat-resistant wire harness 20 of various forms can be realized in accordance with the wiring condition and the wiring layout.
如上所述，根據本發明，可以提供一種儘管使用氟樹脂纖維作為纖絲的材質，耐彎曲性也優異的耐熱帶型電纜及其製造方法以及耐熱線束。 As described above, according to the present invention, it is possible to provide a heat-resistant tape type cable which is excellent in bending resistance, although a fluororesin fiber is used as a material of the filament, a method for producing the same, and a heat-resistant wire harness.
