Described power line and transition lead wire adopt silver-bearing copper soldering processes to weld.
Described transition lead wire is silver wire or nickel down-lead.
Described power line is polyimide film insulation silver-plated copper wire.
In described outer Sealed casing pipe, encapsulation high-temp epoxy machine glue, fixes with high temperature inorganic glue between internal layer sealed tube and insulating sleeve.
The beneficial effects of the utility model are: because the utility model comprises internal layer Sealed casing pipe and outer Sealed casing pipe, the transition lead wire for being electrically connected with power line by the heater strip of heater is provided with in described internal layer Sealed casing pipe, two transition lead wires overlap outward respectively insulating sleeve, the outer two ends of stretching out insulating sleeve respectively, two ends of transition lead wire, transition lead wire one end with stretch into outer Sealed casing pipe power line and weld, the other end is used for welding with the fine electrical heating wire in heater, insulating sleeve is disposed side by side in internal layer Sealed casing pipe, be fixed in internal layer Sealed casing pipe by high temperature inorganic glue, described outer Sealed casing pipe is arranged on internal layer sealing shroud, filled high-temperature organic sealing material in it, by internal layer Sealed casing pipe, the solder joint of power line and power line and transition lead wire seals, form power line sealing device, during assembling, first internal layer Sealed casing pipe is inserted in the power line installing hole of cover of heater, welded seal, two transition lead wires (assembling electrical heating wire) penetrate internal layer Sealed casing pipe, and put insulating sleeve, fix with high temperature inorganic glue, transition lead wire welds with power line, put outer sealed tube, encapsulation high-temp epoxy glue.What power line sealing device adopted is double-layer sealing structure, efficiently solves the sealing transition problem of the power line of limited space, and each part match mounting process problem.
Between power line and the heater strip of heater, adopt transition lead wire, adopt the object of transition lead wire to be realize between two power lines by the insulating sleeve be enclosed within transition lead wire and power line and inside and outside layer sleeve pipe comprise insulation between heater housing.As directly power line being connected with electric heating element, naked road part can not put insulating sleeve, and (diameter dimension is little, just can not be arranged on too greatly internal layer Sealed casing pipe interior), just can not realize between two power lines and power line and inside and outside layer sleeve pipe comprise insulation between heater housing.
Because locus is narrow and small, power supply input lead section adopts outer Sealed casing pipe internal layer Sealed casing pipe double-layer seal mode, and the sealing in order to solder joint and naked line conductor is installed.The power line installing hole of cover of heater is little (lightweight, miniaturized sheathed heater structural requirement), the internal layer Sealed casing pipe of design is arranged in the power line installing hole of cover of heater, the transition lead wire of insulating sleeve on installation sleeve in it, transition lead wire welds with power line again, because solder joint diameter of section is larger than transition lead wire diameter, insulating sleeve can not be passed, so the outer Sealed casing pipe of design is enclosed within internal layer Sealed casing pipe, filled high-temperature epoxy glue in its space, thus the sealing realizing solder joint and naked line conductor is installed.
Described transition lead wire is silver wire or nickel down-lead.Described power line is polyimide film insulation silver-plated copper wire.Polyimide film insulation silver-plated copper wire and transition silver wire or nickel down-lead, and transition lead wire and microfilament heater strip adopt silver-bearing copper soldering processes, solder joint is solid and reliable, efficiently solves microfilament tie point strength problem.
In a word, it is reliable that the utility model possesses structural manufacturing process, simple and easy to do, moisture resistant performance is good, good insulation preformance, thus improve the reliability of small-sized sheathed heater power line seal section.
Be further described below in conjunction with the drawings and specific embodiments.
