Summary of the invention

The purpose of this utility model is: proposes one and can guarantee wire rod fail safe, and the Rapid Thermal wire stripper of peeling clean.

The technical solution of the utility model is: a kind of Rapid Thermal wire stripper, comprises DC current regulator power supply [10], heat fusing device [9], connects wire [8].It is characterized in that, heat fusing device [9] is made up of combustion wire [1], stuck-module [2], standing screw [3], control switch [4], heat fusing device shell [5], fixed head [6], hold-down screw [7], connection wire [8], wherein, by standing screw [3], combustion wire [1] two ends are connected with stuck-module [2], control switch [4] and stuck-module [2] are connected on heat fusing device shell [5].Described combustion wire [1] material is that the trade mark is the nichrome of Cr5Ni60.Described combustion wire [1] length is between 2 centimetres to 5 centimetres.

The utility model has the advantages that:

Structurally, simply light and handy, volume is little, is easy to carry for this hot wire stripper; Usability aspect, easy operating, requires lower to operator; Aspect economical and practical, with low cost, wire stripping is fast, practical, wire stripping is effective, and wire stripping is neat, wire inner wire and cover in order contents melted, not damaged, the useful life of having improved wire; Aspect the scope of application, applicable to polytype (different materials, wire diameter) wire; Aspect the scope of application, can be widely used in military, civilian electronic wire peeling and be suitable for, be convenient to popularize.

Since this wire stripper is made, always for the production of scene, use wire stripper to carry out verification experimental verification.Adopt same wire, with mechanical wire stripping and 10 contrasts of hot wire stripper wire stripping, then carry out life test (wire creasy is carried out to cripping test, and number of times when record damages, as the life-span) respectively, hot wire stripper raising wire useful life is more than 3 times.

Embodiment

Below in conjunction with accompanying drawing, operation principle of the present utility model and operating state are described in detail.

The operation principle of hot wire stripper

Adopt nichrome wire to make combustion wire, make combustion wire heating by controlling current flow heats, the short time is melted conductor casing around, reaches the object of wire stripping.

Nichrome wire is a kind of fusing point very high (1400 ℃ of left and right), and density is large, the alloy that resistivity is little, and it can keep high strength under the condition of high temperature, and plasticity is strong, and structure is not yielding, and radiance is high, nonmagnetic, and corrosion resistance is strong, long service life.In the time adopting it to carry out hot melt wire stripping, its radiating surface temperature moment can reach more than 350 ℃, rapidly conductor casing is carried out to heat fusing.

When a direct current supply voltage adds on nickel chromium triangle metallic resistance silk by controller switches, resistance wire is burnt red by large electric current because of moment, emit heat, surface temperature can reach 400 ℃, and contrectation stripping wire can melt conductor casing fast and not make wire inner wire impaired.

If supply voltage is U, nickel chromium triangle metallic resistance silk resistance is R, and the electric current that flows through resistance wire is I, has: I=U/R

According to Joule law, liberated heat is Q=0.24 × (U ²/ R) × t (1)

T is conduction time

Again because R=ρ L/s (2)

Wherein: ρ---the resistivity of nickel filament

L---nickel filament length,

S---nickel filament cross-sectional area

(2) are brought into (1) formula, liberated heat

Put=0.24 × (U of Q ²Л r ²t)/ρ L (3)

Consume according to put=Q of law of conservation of energy: Q suction+Q

Because heating time is very short, general several seconds, thermal losses was very little, negligible.

: put=Q of Q inhales

That is: 0.24 × (U ²Л r ²t)/ρ L=cm Δ T

ΔT=0.24×（U ²Лr ²t）/ρLcm

=0.24×（U ²ЛD ²t）/ρLc(dЛLD ²)

=(0.24/ρcd)×(U/L) ²×t

Make K*=0.24/ ρ cd

Δ T=K* × (U/L) ²× t (4)

(4) in formula: the specific heat of c — Nie Chrome silk

The proportion of d — Nie Chrome silk

The transformation temperature (temperature rise) of Δ T — Nie Chrome silk

Visible, at short notice, temperature variation and its diameter of nickel-chromium resistance wire heating are irrelevant, and have relation with its specific heat, proportion and resistivity.Square being directly proportional of variations in temperature and its voltage length ratio.

In the time selecting nickel Chrome silk, the direct voltage 5VDC of 5 centimetres of length, trade mark Cr5Ni60, K* was 0.05447,1 second, 544.7 ℃ of nickel filament variations in temperature, that is and, nickel filament surface temperature can reach more than 560 ℃.

Connected mode as shown in Figure 3, couples together heat fusing device 9 and DC current regulator power supply 10 with wire 8.

Working method is: in the time coupling together by Fig. 3 mode, first open the switch of DC current regulator power supply 10, pin the control switch 4 on heat fusing device 9, Voltage-output to the combustion wire 1 of adjusting DC current regulator power supply 10 is burnt red, unclamps control switch 4.Pick up wire to be stripped 11 with left hand, the right hand is picked up heat fusing device 9, near wire to be stripped 11, pins control switch 4, by burning the crust of red combustion wire cutting wire to be stripped 11, after dissolving, unclamps control switch 4, puts down heat fusing device 9, takes off wire sheath.See Fig. 4.
