The various control system that are installed in automobile etc. possess usually: the sensor element that physical quantitys such as temperature, speed, pressure is changed into the signal of telecommunication; The signal that sensor element produced is carried out the ECU (Electric Control Unit, electronic control unit) of computing; And the actuator parts of working according to the output signal of ECU.Sensor element, ECU and actuator parts interconnect by the cable that transmits signal.In the anti-lock braking system (ABS) as one of this control system, sensor element is arranged near the wheel speed sensors the wheel.Wheel speed sensors is used for the environment that drenched by water in vehicle traveling process.Therefore, not only require wheel side sensor to have water proofing property, but also require the connecting portion between transducer and the cable to have water proofing property.
Consider from aspects such as dimensional accuracy or mechanical strength, shaping processabilities, case material as wheel speed sensors, select PBT mylar or 6-nylon, 6 such as (polybutylene terephthalate (PBT)s), 6-nylon, 6T-nylon polyamides such as (aromatic nylons) always.In addition, have excellent chemical-resistant and anti-flammability because fusing point is heat-resistant engineering plastic-polyphenylene sulfide (PPS) above about 280 ℃, so it is as the case material of wheel speed sensors.
On the other hand, as the cable of fifth wheel speed sensors and ECU, use the insulated cable that forms with restrictive coating coated insulation electric wire periphery.People not only require restrictive coating to have flexibility, resistance to wear, resistance to bend(ing), resistance to water etc., but also require the connecting portion between transducer and the cable to have water proofing property.Therefore, for example, as disclosed in No. 3428391 communiques of Japan Patent, the TOHKEMY 2006-156407 communique, someone has proposed such method: employing can form restrictive coating with the resin that the engineering plastics generation heat fusing that forms housing adheres to, and when the ejection formation of housing housing and restrictive coating heat fusing is adhered to sealing.
In addition, in No. 3428391 communiques of Japan Patent, TOHKEMY 2006-156407 communique, as the resin that satisfies above-mentioned requirements, proposed based on the crosslinked body of the resin combination of the mixture that contains TPUE and thermoplastic polyester elastomer or based on the crosslinked body of the resin combination of the mixture that contains TPUE and thermoplastic polyamide elastomer.
When contained the ingredients of a mixture ratio was in the scope of regulation in the crosslinked body of above-mentioned resin combination, the crosslinked body of above-mentioned resin combination can adhere to mylar or polyamide heat fusing.Therefore, under the situation that housing is made of these resins, do not use seal members such as O circle, just can guarantee the water proofing property of connecting portion.Yet, do not find to have the adhering resin of excellent heat fusion as yet with PPS.So as the material of the restrictive coating that forms cable, people require and can make the suitable material that the housing heat fusing adheres to PPS.
Summary of the invention
The invention provides a kind of like this insulated cable: it comprises with PPS having the adhering restrictive coating of excellent heat fusion, and adheres to by terminal part and the PPS system housing heat fusing with cable, can guarantee that the connecting portion between cable and the housing has water proofing property.In addition, the invention provides the control system parts and the manufacture method thereof of the water proofing property excellence of the connecting portion between cable and the housing.
The inventor furthers investigate above-mentioned problem.Found that, contain the resin combination of the above thermoplastic polyester elastomer of regulation ratio and the heat fusing adhesiveness excellence of PPS.The inventor also finds, with PPS as under the situation of case material, can the long term maintenance insulated cable and housing between the water proofing property of connecting portion, do not require characteristic and do not damage resistance to wear or resistance to bend(ing) etc.
To achieve these goals,, provide a kind of like this insulated cable according to first embodiment of the present invention: the restrictive coating that it possesses the insulated electric conductor of single core or multicore and is formed on the insulated electric conductor periphery, and it is used for adhering to the polyphenylene sulfide heat fusing.According to insulated cable of the present invention, restrictive coating is made of the crosslinked body of resin combination, and this resin combination contains the thermoplastic polyester elastomer that accounts for more than the 45 overall weight % of resin combination.
According to said structure, restrictive coating is made of the crosslinked body of resin combination, and this resin combination contains the above thermoplastic polyester elastomer of 45 weight % that accounts for resin combination integral body, therefore can improve the heat fusing adhesiveness of restrictive coating and PPS.
The forming temperature of PPS is about 310～360 ℃, and this temperature is higher than the melt temperature of the resin combination that contains the above thermoplastic polyester elastomer of 45 weight %.Therefore, under PPS being penetrated with situation about when forming housing cable seal being connected, restrictive coating as long as do not take place crosslinked just can fusion.Thereafter, it is crosslinked that the resin combination that contains thermoplastic polyester elastomer is taken place, thereby the restrictive coating of molten condition is solidified.For example, in trimethylol-propane trimethacrylate, triallyl cyanurate or triallyl isocyanate equimolecular, blend has the polyfunctional monomer of a plurality of carbon-to-carbon double bonds, and carries out radiation with ionization radial lines such as accelerated electron beam or gamma-rays, thereby carries out crosslinked.
In addition, also can adopt the heat curing system that utilizes organic peroxide or water crosslinking method etc. and said method diverse ways, wherein said water crosslinking method is: in advance with said mixture and alkoxy silane grafting (graft), and in the presence of catalyst such as organic tin compound, thereby material after the grafting is contacted carry out crosslinked with water or steam.Yet, mainly consider from the viewpoint of crosslinking Treatment speed, used the method for ionization radial lines such as accelerated electron beam easy and productivity is high.
In above-mentioned insulated cable, the ratio of the thermoplastic polyester elastomer in the resin combination preferably surpasses 80 weight %.
In the resin combination that constitutes restrictive coating, when the ratio of thermoplastic polyester elastomer surpasses 80 weight %, further improved the heat fusing adhesiveness of restrictive coating and PPS.According to No. 3428391 communiques of Japan Patent, TOHKEMY 2006-156407 communique, for for the heat fusing adhesiveness of mylar or polyamide, the ratio of the thermoplastic polyester elastomer in the resin combination is preferred when 80 weight % are following.In contrast, according to the present invention, for for the heat fusing adhesiveness of PPS, the ratio of the thermoplastic polyester elastomer in the resin combination is preferred when surpassing 80 weight %.Therefore, according to the opinion in the past in above-mentioned each document, can not predict the formation of the present patent application at all.
In above-mentioned insulated cable, thermoplastic polyester elastomer is the block copolymer of soft section of the hard section of crystalline state and amorphous state, and wherein said amorphous state is preferably the polyethers polymer for soft section.
As hard section of crystalline state, can enumerate polybutylene terephthalate (PBT) polymer such as (PBT).As soft section of amorphous state, can enumerate: polymer that constitutes by polyformaldehyde glycol such as polytetramethylene ether diols or the polymer that constitutes by polyester-diols such as polycaprolactone glycols.As soft section of amorphous state, when polyethers polymer such as use polyformaldehyde glycol, can obtain the formed body of flexibility excellence, therefore preferred this polymer that uses.
In above-mentioned insulated cable, preferably contain TPUE in the resin combination.
The resin combination that constitutes restrictive coating can contain other resin that mixes with thermoplastic polyester elastomer, as long as this resin combination contains the thermoplastic polyester elastomer in the aforementioned proportion scope.As other resin, for example can enumerate graft resin, the thermoplastic elastomer (TPE) of TPUE, polyethylene, polyacrylic bipolymer and terpolymer, these polymer, the resin that derives from plant, Biodegradable resin, engineering plastics etc.In these resins, consider the preferred thermoplastic polyurethane elastomer from requiring viewpoints such as thermal endurance, resistance to wear.
TPUE is segmented polyurethane and the soft section polymer that forms through chimeric copolymerization that is made of the difunctional polyalcohol.The condensation polymer that segmented polyurethane is formed by short-chain diols such as vulcabond such as toluene di-isocyanate(TDI) and ethylene glycol constitutes.According to soft section kind, TPUE can be divided into polyethers, caprolactone class, adipate ester class, kind such as polycarbonate-based.
In above-mentioned insulated cable, form the preferred selected self-contained nitrogen combustion inhibitor of resin combination of restrictive coating or one or more fire-retardantization of fire retardant in two bromine phthalimide, two (bromo phenyl) ethane of ethylene and the dibromo phenyl terephthalamide.
Thermoplastic polyester elastomer has combustibility, therefore when the cable of fire-retardantization of preparation, the restrictive coating that has used this resin combination need be carried out fire-retardantization or insulating barrier or interlayer are carried out fire-retardantization to guarantee anti-flammability outside restrictive coating.As the method for guaranteeing anti-flammability, be known that the method for blending fire retardant agent, in the method, if the resin combination after fire-retardantization is applicable in the restrictive coating of insulated cable of the present invention, the qualified possibility height of burning test of JASO standard (Japanese car industry meeting) or iso standard then.That is, can obtain safe cable.
Yet the adhesive strength after restrictive coating and case material heat fusing adhere to is subjected to the influence of the fire retardant kind of blend in elastomer blends.As fire retardant, contain nitrogen combustion inhibitor or two bromine phthalimide, two (bromo phenyl) ethane and two (bromo phenyl) terephthalamides of ethylene etc. if use, then can be with housing and restrictive coating heat fusing adhesion securely.As containing nitrogen combustion inhibitor, for example can enumerate melmac or melamine cyanurate etc.
On the other hand, if use PBDEs such as deca-BDE or octabromodiphenyl ether as fire retardant, the adhesive strength after then housing and restrictive coating heat fusing adhere to is sometimes insufficient.
The degree of cross linking of resin combination that forms restrictive coating is high more, and the influence of the adhesive strength after the heat fusing that the fire retardant kind is caused adheres to is just remarkable more.Be added with PBDEs such as deca-BDE forms under the situation of restrictive coating as the resin combination of fire retardant in use, if when injection molding, the degree of cross linking is brought up to the level that can keep the shape of restrictive coating really, the adhesive strength after the heat fusing that then sometimes can not obtain housing and restrictive coating adheres to.
In contrast, contain in use under the situation of fire retardants such as nitrogen combustion inhibitor, two bromine phthalimide, two (bromo phenyl) ethane or two (bromo phenyl) terephthalamides of ethylene, even when injection molding, the degree of cross linking brought up to the level that can keep the shape of restrictive coating really, also therefore housing and restrictive coating heat fusing adhesion securely can be able to be obtained desirable water resistance.In addition, also has such advantage: will contain nitrogen combustion inhibitor (particularly melamine cyanurate) blend in resins such as polyurethane elastomer the time, and decompose even under hot conditions, also be difficult to.
