From the viewpoint of dimensional accuracy or mechanical strength, shaping processability etc., case material as wheel speed sensors, select mylar or the 6-nylon, 6 such as PBT (polybutylene terephthalate (PBT)), the polyamides such as 6-nylon, 6T-nylon (aromatic nylon) always.In addition, because fusing point is that 280 ℃ of heat-resistant engineering plastic-polyphenylene sulfides (PPS) more than left and right have excellent chemical-resistant and anti-flammability, so it is as the case material of wheel speed sensors.
On the other hand, as the cable that connects wheel speed sensors and ECU, use the insulated cable forming 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 cable to have water proofing property.Therefore, for example, disclosed in No. 3428391 communiques of Japan Patent, 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 housing and restrictive coating heat fusing is adhered to seal when the ejection formation of housing.
In addition, in No. 3428391 communiques of Japan Patent, TOHKEMY 2006-156407 communique, as the resin that meets above-mentioned requirements, the crosslinked of the resin combination that the crosslinked of the resin combination that the mixture that has proposed take to contain TPUE and thermoplastic polyester elastomer is main body or the mixture that contains TPUE and thermoplastic polyamide elastomer of take are main body.
In the crosslinked of above-mentioned resin combination, in contained the ingredients of a mixture ratio scope in regulation time, the crosslinked of above-mentioned resin combination can adhere to mylar or polyamide heat fusing.Therefore, in the situation that housing consists of these resins, do not use the seal members such as O circle, just can guarantee the water proofing property of connecting portion.Yet, not yet find to there is the adhering resin of excellent heat melting with PPS.So as the material that forms the restrictive coating of cable, people require the suitable material that can adhere to PPS housing heat fusing processed.
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 melting, and by the terminal part of cable and PPS housing heat fusing processed are adhered to, can guarantee that the connecting portion between cable and housing has water proofing property.In addition the invention provides, parts and the manufacture method thereof for control system of the water proofing property excellence of the connecting portion between cable and housing.
The inventor conducts in-depth research above-mentioned problem.Found that, the heat fusing adhesiveness of the resin combination that contains thermoplastic polyester elastomer more than regulation ratio and PPS is excellent.The inventor also finds, by PPS as case material in the situation that, can long term maintenance insulated cable and housing between the water proofing property of connecting portion, and do not damage resistance to wear or resistance to bend(ing) etc., do not require characteristic.
To achieve these goals, according to the first embodiment of the present invention, provide a kind of like this insulated cable: the restrictive coating that it possesses the insulated electric conductor of single core or multicore and is formed on insulated electric conductor periphery, and it is for adhering to polyphenylene sulfide heat fusing.According to insulated cable of the present invention, restrictive coating consists of the crosslinked of resin combination, and this resin combination contains the thermoplastic polyester elastomer accounting for more than 45 overall % by weight of resin combination.
According to said structure, restrictive coating consists of the crosslinked of resin combination, and this resin combination contains thermoplastic polyester elastomers more than 45 % by weight that account for resin combination integral body, therefore can improve the heat fusing adhesiveness of restrictive coating and PPS.
The forming temperature of PPS is 310～360 ℃ of left and right, and this temperature is higher than the melt temperature of the resin combination that contains thermoplastic polyester elastomers more than 45 % by weight.Therefore,, in the situation that cable seal is connected when PPS is penetrated to form housing, restrictive coating just can melting as long as do not occur to be cross-linked.Make the resin combination that contain thermoplastic polyester elastomer occur be cross-linked, thereby the restrictive coating of molten condition solidified thereafter.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 is cross-linked.
In addition, also can adopt and utilize the heat curing system of organic peroxide or water crosslinking method etc. and said method diverse ways, wherein said water crosslinking method is: in advance by said mixture and alkoxy silane grafting (graft), and under the existence of the catalyst such as organic tin compound, thereby make the material after grafting contact and be cross-linked with water or steam.Yet, mainly from the viewpoint of crosslinking Treatment speed, consider, used that the method for the ionization radial lines such as accelerated electron beam is easy and productivity is high.
In above-mentioned insulated cable, the ratio of the thermoplastic polyester elastomer in resin combination preferably surpasses 80 % by weight.
In forming the resin combination of restrictive coating, when the ratio of thermoplastic polyester elastomer surpasses 80 % by 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 the heat fusing adhesiveness with mylar or polyamide, the ratio of the thermoplastic polyester elastomer in resin combination is preferred in 80 % by weight when following.In contrast, according to the present invention, for the heat fusing adhesiveness with PPS, the ratio of the thermoplastic polyester elastomer in resin combination is preferred when surpassing 80 % by 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 soft section of wherein said amorphous state is preferably polyethers polymer.
As hard section of crystalline state, can enumerate the polymer such as polybutylene terephthalate (PBT) (PBT).As soft section of amorphous state, can enumerate: the polymer being formed by polyformaldehyde glycol such as polytetramethylene ether diols or the polymer being formed by polyester-diols such as polycaprolactone glycols.As soft section of amorphous state, when using the polyethers polymer such as polyformaldehyde glycol, can obtain the formed body of flexibility excellence, therefore preferably use this polymer.
In above-mentioned insulated cable, in resin combination, preferably contain TPUE.
The resin combination that forms restrictive coating can contain other resin mixing with thermoplastic polyester elastomer, as long as this resin combination contains the thermoplastic polyester elastomer within the scope of aforementioned proportion.As other resin, such as enumerating 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, from requiring the viewpoints such as thermal endurance, resistance to wear to consider, preferred thermoplastic polyurethane elastomer.
TPUE is segmented polyurethane and the soft section of polymer forming through chimeric copolymerization consisting of difunctional polyalcohol.The condensation polymer that segmented polyurethane is formed by short-chain diols such as the vulcabond such as toluene di-isocyanate(TDI) and ethylene glycol forms.According to the kind of soft section, TPUE can be divided into polyethers, caprolactone class, adipate ester class, the 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 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 to be carried out to fire-retardantization or insulating barrier or interlayer are carried out to 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 possibility that burning test of JASO standard (Japanese car industry meeting) or iso standard is qualified is high.That is, can obtain safe cable.
Yet the adhesive strength after restrictive coating and case material heat fusing adhere to is subject to the impact of the fire retardant kind of blend in elastomer blends.As fire retardant, if used containing nitrogen combustion inhibitor or two bromine phthalimide, two (bromo phenyl) ethane and two (bromo phenyl) terephthalamides of ethylene etc., can be by housing and restrictive coating heat fusing adhesion securely.As containing nitrogen combustion inhibitor, such as enumerating melmac or melamine cyanurate etc.
On the other hand, if use the PBDEs such as deca-BDE or octabromodiphenyl ether as fire retardant, the adhesive strength after housing and the adhesion of restrictive coating heat fusing is sometimes insufficient.
The degree of cross linking of the resin combination of formation restrictive coating is higher, and the impact of the adhesive strength after the heat fusing that fire retardant kind is caused adheres to is just more remarkable.In the situation that form restrictive coating with being added with the resin combination of the PBDEs such as deca-BDE as fire retardant, if the degree of cross linking is brought up to the level that can really keep the shape of restrictive coating when injection molding, the adhesive strength after the heat fusing that sometimes can not obtain housing and restrictive coating adheres to.
In contrast, in the situation that using containing fire retardants such as nitrogen combustion inhibitor, two bromine phthalimide, two (bromo phenyl) ethane or two (bromo phenyl) terephthalamides of ethylene, even if the degree of cross linking is brought up to the level that can really keep the shape of restrictive coating when injection molding, also can, by housing and restrictive coating heat fusing adhesion securely, therefore can obtain desirable water resistance.In addition, also have advantages of such: will be containing nitrogen combustion inhibitor (particularly melamine cyanurate) blend in the resins such as polyurethane elastomer time, even be also difficult under hot conditions, decompose.
