Description
Technical field
The invention belongs to aircrafts to be electrically connected designing technique, is related to a kind of high temperature resistant minor diameter insulation switching.
Background technology
In the products such as pressure tube, incidence vane heating circuit, what sheathed heater was connect with its power supply circuit turns
It is one of important feature in heating circuit to connect son, affects realization and the functional reliability of product heating function.
For switching generally using glue seal structure, special 200 DEG C of epoxy adhesive highest heatproof used can permanent worker at present
It is 100 DEG C to make temperature, but can not be resistant to the high temperature more than 300 DEG C or more.Meanwhile switching of glue seal structure is when used for a long time
There is aging, problems of crack, influence product reliability and service life.
The development of new product is proposed and to be worked for a long time in 300 DEG C of temperature environments to switching, and outer diameter is less than Φ 5mm,
The requirement of 500M Ω dielectric strengths under 500V DC voltages.Current switching can not meet above-mentioned requirements.
Invention content
The purpose of the present invention is：A kind of high temperature resistant minor diameter insulation switching is provided, solving switching can not long-term work
The problem of under 300 DEG C of temperature environments.
The technical scheme is that：A kind of high temperature resistant minor diameter insulation switching, including switching subshell 1, jewel axis
Hold 2, switching casing 3；It is fixed between the switching subshell 1 and switching casing 3 using glass sintering；The switching subshell 1
Iron-cobalt-nickel glass sealing alloy material is used with switching casing 3；The switching 3 outer cover high-temperature insulation fibre sleeving 4 of casing, ensures electricity
The insulating requirements on road；
Described switching 3 one end of casing is connect with the internal thread of sheathed heater 6 by crimping form, and the other end is led with external
The inner core of line 5 is connected by crimping form, so as to reach the connection of circuit.
The beneficial effects of the invention are as follows：First, all structural members select inorganic material in of the invention, ensure that switching can be grown
Phase is resistant to 300 DEG C of high temperature, and heatproof is up to 500 DEG C in short-term.Second, the connection of circuit employs crimping form, avoids using tin
The low-temperature weldings techniques such as weldering, in addition to high temperature resistant is ensured, it is also ensured that be reliably connected.Third, using jewel bearing, high-temperature insulation
The materials such as fibre sleeving, glass sintering and method, to meet the insulating requirements of switching.4th, using glass sintering fixed form,
The diameter of switching is effectively reduced, meets the requirement that diameter is not more than Φ 5mm.
Description of the drawings
Fig. 1 is the structure diagram of high temperature resistant minor diameter of the present invention insulation switching.
Wherein, 1- transfer subshell, 2- jewel bearings, 3- switchings casing, 4- high-temperature insulations fibre sleeving, lead outside 5-
Line, 6- sheathed heaters.
Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described further.
A kind of high temperature resistant minor diameter insulation switching of the present invention, including switching subshell 1, jewel bearing 2, switching casing 3；
It is fixed between the switching subshell 1 and switching casing 3 using glass sintering,；The switching subshell 1 and switching casing 3 are equal
Using iron-cobalt-nickel glass sealing alloy material, coefficient of thermal expansion is small, can effectively avoid the glass sintering position caused by temperature change
Cracking.Switching 3 outer cover high-temperature insulation fibre sleeving 4 of casing ensures the insulating requirements of circuit.
The iron-cobalt-nickel glass sealing alloy material trademark is 4J29, performs standard YB/T5231-2006.
The high-temperature insulation fibre sleeving trade mark used is QKJYT03H.
Glass sintering used is QKBF10 with the glass dust trade mark.
Described switching 3 one end of casing is connect with 6 internal thread of sheathed heater by crimping form, the other end and external conducting wire
5 inner cores are connected by crimping form, so as to reach being reliably connected for circuit.
The switching subshell 1 is connect with sheathed heater by flame welding form, and sheathed heater 6 and switching are outer
The copper wire filling of gap wound into spring shape between shell 1, prevents solder from excessively overflowing to inside.
The installation and application method of the present invention is as follows：
A) 6 internal thread of sheathed heater is stripped out；
B) jewel bearing 2 is sleeved on to the internal thread root stripped out；
C) as shown in Figure 1, sheathed heater 6 is connect with switching, internal thread should be in switching 3 endoporus of casing；
D) by shown position crimping internal thread and switching casing 3；
E) gap between switching subshell 1 and sheathed heater 6 is filled with the copper wire of wound into spring shape；
F) with Welding fixed transfer subshell 1 and sheathed heater 6；
G) conducting wire 5 is stripped out into inner core, and connect and crimp with switching 6 other end of casing；
H) it in switching 3 outer cover high-temperature insulation fibre sleeving 4 of casing, and is fastened with copper wire.
The present invention has tested the incidence vane on aircraft, by verification, connects at a temperature of disclosure satisfy that 300 DEG C
The requirement of continuous work, the effective guarantee development of incidence vane and mating task.
