Description

Copper alloy wire, twisted wire, coaxial cable, its manufacture method and multicore cable
Technical field
The present invention relates to have high strength, high conduction performance, and its intensity also is difficult to reduce in the operation that applies heat load of squeeze job, solder operation and so on, heat resistance is also very excellent superfine copper alloy wire, its twisted wire, insulated wire, coaxial cable and their manufacture method and use the multicore cable that their make.
Background technology
The anti-bending cable employed conductor materials such as (for example, probe cable) that anti-bending cable of using as electronic equipment (for example, the automatics cable) or Medical Devices are used uses the alloy with high-strength and high-conductivity usually.
Now, as the copper alloy wire made from a large amount of levels of production, can enumerate the Cu-Sn alloy wire and the Cu-Sn-In alloy wire of the economical that can produce with continuous casting and milling method, and be widely used as electronic equipment with and the conductor material of the anti-bending cable used of Medical Devices.In addition, other copper alloy wire also is applicable to various fields according to the various characteristics of product cost and copper alloy wire.
In recent years, along with the miniaturization of miniaturization, lightweight or the Medical Devices of electronic equipment, the conductor diameter of their employed electric wires also requires superfine, reaches the following degree of conductor diameter requirement Φ 0.03mm.Complicated along with the ultrasonic endoscope head can be found the tendency that ultrasonic endoscope has further the direction to multiple-core (200-260 core) develop with cable.On the other hand, in order to reduce patient's misery, the diameter that reduces endoscope head has also been improved requirement.Also be significant the employed curling cable etc. when the requirement of thin footpathization is performed the operation in implementing in blood vessel near the blood vessel of the affected part of being scheduled to.
In addition, not only require thin footpathization recently, and in order to improve resistance to bend(ing) and to increase transmission capacity, also the strong request exploitation has the conductor material of high-strength characteristic and high conductive characteristic simultaneously.
The copper alloy that above-mentioned Cu-Sn alloy wire and Cu-Sn-In alloy wire have generated by added Sn in the reverberatory refining copper as parent metal constitutes.Yet the Cu-Sn alloy wire must increase the addition of Sn in order to gain in strength, its result, and its conductance reduction will take into account intensity and conductance two aspects are difficult.
On the other hand, as the copper alloy that has high intensity and high conductance simultaneously, the Cu-Ag alloy comes into one's own.The Cu-Ag alloy that tensile strength and conductance are good for example passes through, the Cu-Ag alloy that will contain 1.0-15 weight % in copper carries out following processing and makes: 1. the bar that casting is obtained carries out cold working and makes after its reduction of area reaches more than 70%, 2. under 400-500 ℃ temperature, carry out 1-30 hour heat treatment, subsequently, 3. carry out reduction of area and reach cold working (with reference to patent documentation 1-TOHKEMY 2001-40439 communique) more than 95.
In addition, also can manufacture superfine copper alloy twisted wire as follows: the silver that adds 0.1-1.0 weight % in fine copper forms the Cu-Ag alloy, making diameter again is that 0.01-0.8mm, tensile strength are the above single line of 600MPa, with this single line with predetermined bar number stranded after, make (with reference to patent documentation 1-TOHKEMY 2001-234309 communique) by this twisted wire being heat-treated with the stress of eliminating when stranded.
When this superfine copper alloy wire that is made of the Cu-Ag alloy is used as anti-bending cable, generally be to coat in skin extruding to use after fusing point is a insulator about 300 ℃, but in this squeeze job, because the heat of the insulator when coating and the heat load of extruder head reduce mechanical property, the especially tensile strength of superfine copper alloy wire.And then, endways in the processing, owing to the heat of about 300-350 ℃ flatiron of solder operation significantly reduces the tensile strength of the superfine copper alloy wire of terminal part.Therefore, after squeeze job and solder operation, then be difficult to sometimes guarantee electrical characteristic and mechanical property both, especially because the reduction of tensile strength, the Mechanical Reliability to cable and cable end piece processing part produces infringement greatly sometimes.Thereby, as to the desired characteristic of superfine copper alloy wire, not only to have high intensity and high conductance simultaneously, but also require its intensity not because of standing the thermal stability that thermal processs such as squeeze job reduce.
In addition, for example, in the cable that probe cable that diagnostic ultrasound equipment is used or ultrasonic endoscope are used, owing to use diameter to be the superfine wire below the 0.025mm, thereby, then become problem with the corresponding resistance of such conductor size.Concrete is according to American wire gage (AWG-America Wire Gauge) standard, to require really to reach the superfine copper alloy twisted wire of thin footpathization and good this two aspect of electrical characteristic.The pass of AWG standard and twisted wire structure (twisted wire radical/line footpath) is 42AWG (7/0.025), 43AWG (7/0.023), 44AWG (7/0.020), 45AWG (7/0.018), 46AWG (7/0.016), 48AWG (7/0.013), 50A
Yet, for the Cu-Ag alloy of patent documentation 1 record, as the method that it is reached have simultaneously high tensile strength and high conductance to be taken into account, owing to be under specific temperature, it to be carried out the heat treatment of (1-30 hour) for a long time, thereby, not only reduced production efficiency but also improved cost.In addition, the thermal process during for the heat load that applied by squeeze job etc. and intensity is reduced had not both had any relating to, and did not take some countermeasures yet.Have again, for also not having any relating to the corresponding resistance of the conductor size of superfine diameter.
On the other hand, in the superfine copper alloy twisted wire of patent documentation 2, though record silver as the interpolation element of copper alloy, addition arrives 0.1-1.0 weight % less, does not look to improving intensity with it.In addition, in this superfine copper alloy twisted wire, though with the flexural property that improves the plastic deformation field be purpose mainly guaranteed the elongation characteristic more than 5%, for having paid attention to the elongation characteristic, its tensile strength must reduce.Therefore, especially for use line through as the electronic equipment of the superfine wire below the 0.025mm with cable or cable for medical apparatus, for example there is its undercapacity in the cable applications used of the probe cable used of diagnostic ultrasound equipment or ultrasonic endoscope, the inadequate problem of bendability.

Below, the superfine copper alloy wire that has formed coating, superfine copper alloy twisted wire are described.
Fig. 3 represents the example of plating superfine copper alloy wire.
Plating superfine copper alloy wire 2 is the periphery formation coating 6 at superfine copper alloy wire shown in Figure 11.Coating 6 is mainly considered from the corrosion resistance and the solder connectivity aspect that improve superfine copper alloy wire 1, is formed the coating that is made of tin (Sn), silver (Ag) or nickel (Ni) usually.
In addition, as shown in Figure 4, with 7 plating superfine copper alloy wires, the 2 stranded superfine copper alloy twisted wires 4 of plating of also can making.
Below, the manufacture method of the superfine copper alloy wire 1 and the superfine copper alloy twisted wire 3 of present embodiment is described.
At first, in fine copper, add the silver of 1-3 weight %, preferably add the silver of 1.5-2.5 weight %, generate copper alloy, then, through wire drawing processing or carry out intermediate heat-treatment and make line and directly be the superfine wire of 0.025-0.010mm.At this moment, also can in the course of processing, carry out zinc-plated (Sn), silver (Ag) or nickel (Ni) and handle, finally make line and directly be the superfine wire of 0.025-0.010mm the line surface.
Secondly, resulting superfine copper alloy wire single line or for example 7 stranded superfine copper alloy twisted wires that form that will be scheduled to the bar number are heat-treated under given conditions.Heat treatment is handled 0.2-5 and is carried out second by moving in being heated to 300-500 ℃ heating furnace.
Why being decided to be as heat-treat condition and carrying out under 300-500 ℃ 0.2-5 second, is because if heat treatment temperature is lower than 300 ℃, heat treatment time less than 0.2 second, though then the reduction of tensile strength is little, the increase of conductance is also less and the characteristic that can not obtain requiring.In addition, if heat treatment temperature surpasses 500 ℃, heat treatment time surpasses 5 seconds, though conductance increases, tensile strength significantly reduces, and can not obtain desired characteristic.
Concrete is, by heat-treating under the condition of 300-500 ℃ and 0.2-5 second, can accomplish to make the tensile strength (σ after the heat treatment A1) with respect to the tensile strength (σ before the heat treatment A0) reduced rate [(1-σ A1/ σ A0) * 100%] be below 30%, and, make the conductance (ρ after the heat treatment A1) with respect to the conductance (ρ before the heat treatment A0) increment rate [((ρ A1)/(ρ A0)-1) * 100% be more than 60%].
Carry out the superfine copper alloy wire or the superfine copper alloy twisted wire that obtain after the above processing, its line is 0.025-0.010mm directly, contains the silver of 1-3 weight %, the silver of preferred 1.5-2.5 weight %, its tensile strength is more than the 850MPa, and conductance is more than the 85%IACS, and elongation is 0.5-3.0%; And, through temperature below 350 °, the heat treated of time below 5 seconds, the tensile strength (σ after its heat treated H1) with respect to the tensile strength (σ before the heat treated H0) reduced rate [(1-σ H1/ σ H0) * 100%] below 2%.
If adopt present embodiment, can obtain finish line and directly be the following superfine wire of 0.025mm, can be had simultaneously high-strength characteristic and low resistance characteristic (high conductivity) both, and, even its intensity also is difficult to reduce in the heat loads such as extruding manufacturing process of the coaxial cable that has used superfine wire, also with the superfine copper alloy wire and the superfine copper alloy twisted wire of high-fire resistance.
Therefore, make coaxial cable etc. if use these superfine copper alloy wires, superfine copper alloy twisted wire, just can be applicable to require miniaturization, thin footpathization, in light weight, high resistance to bend(ing) the electronic equipment usefulness and the cable for medical apparatus of performance such as transmission performance is good well.

Below, the 3-23 to embodiment is described, comparative example 3-24, the evaluation result of the superfine copper alloy twisted wire of original routine 3-6.
Table 7 expression be conductance, tensile strength and tensile strength and changes in resistance rate after tensile strength before and after the superfine copper alloy twisted wire of embodiment 3-23, comparative example 3-24, original routine 3-6 is heat-treated and resistance, the heat treatment.
Table 7
[the 7th table] (based on the data of 7 cabling lines)
Figure A20061016877000431
* rate of change=[value before (value after the value-heat treatment before the heat treatment)/heat treatment] * 100%
As shown in table 1, for 7 cabling lines of embodiment 3-5 (43AWG), because interpolation metal concentration and heat-treat condition are suitable, thereby, the reduced rate of tensile strength arrives 6.9-10.8% at most, and the tensile strength after the heating is 910MPa, surpasses the tensile strength 850MPa as desired value.In addition, the reduced rate of resistance also arrives 6.1-7.3% (resistance change rate is more than 6%) significantly greatly, and the resistance after the heating is 6450 Ω/km, can obtain the wire rod of the high conductivity of conductance more than 85%.
Corresponding therewith, 7 cabling lines of the original routine 3-6 (43AWG) of signal bronze, its tensile strength is lower than 850MPa, and then, even original signal bronze line is carried out heat treatment of the present invention (original routine 3-6) equally, its tensile strength also is reduced to 710-730MPa significantly, and the reduced rate of resistance at most only 0.9% is difficult to reach the characteristic that has high tensile strength and high conductivity two aspects simultaneously.
7 cabling lines of original Cu-Sn-In alloy wire (with reference to comparative example 10-24), its tensile strength is lower than 850MPa after heating, can not obtain high-intensity material.
In addition, comparative example 3 is not owing to heat-treat, though its tensile strength height, its resistance still can not obtain the material of the high conductivity of conductance more than 85% up to 6870 Ω/km.
Comparative example 4 is because the interpolation concentration of silver is 0.5 weight % and low excessively, thereby its tensile strength is lower than the 850MPa of desired value, and the reduced rate of resistance is up to 2%, and hence one can see that, and it is difficult to reach the characteristic that has high tensile strength and low resistance two aspects simultaneously.
Comparative example 5 is because the interpolation concentration of silver is 3.5 weight % and too high, thereby, the highest ability 1% of its resistance reduced rate, hence one can see that, and it is difficult to reach the characteristic that has high tensile strength and low resistance two aspects simultaneously.
Comparative example 6 is because heat treatment temperature is low to 250 ℃, thereby its resistance reduced rate is up to 0.5%, and hence one can see that, and it is difficult to reach the characteristic that has high tensile strength and low resistance two aspects simultaneously.
Comparative example 7 since heat treatment temperature up to 600 ℃, thereby the reduced rate of its tensile strength is significantly up to 27.3%, hence one can see that, it is difficult to reach the characteristic that has high tensile strength and low resistance two aspects simultaneously.
Comparative example 8 is because heat treatment time is short to 0.1 second, thereby its resistance reduced rate is up to 1%, and hence one can see that, and it is difficult to reach the characteristic that has high tensile strength and low resistance two aspects simultaneously.
Comparative example 9 is because heat treatment time reaches 6 seconds, thereby its tensile strength reduced rate is 22.1%, and tensile strength is low, and hence one can see that to 810MPa, and it is difficult to reach the characteristic that has high tensile strength and low resistance two aspects simultaneously.
If embodiment 3-23 and comparative example 10-24 are compared, the twisted wire of comparative example 10-24, its resistance reduced rate is up to about 0.8-3.2%, all is the higher wire rod of resistance value.As for comparative example 10-comparative example 24, its tensile strength also is lower than desired value 850MPa.
That is to say, as known from Table 7, as comparative example 10-24, using under the situation of Cu-0.19%Sn-0.19%In alloy that no matter whether heat-treat, its tensile strength all is lower than embodiment 3-23, and its resistance also all is higher than embodiment 3-23.
In addition, as illustrated in the prior art, existing product uses the Cu-0.19%Sn-0.19%In alloy twisted wire without special heat treated, does not carry out other heat treatment.Therefore, even have high conductivity and high-intensity characteristic 7 bursts of twisted wire bare wire stages, but the heating that produces during because of squeeze job (for example 400-300 ℃ 1 second-5 seconds), shown in the alloy twisted wire of comparative example 10-24, its resistance reduced rate is also little, but its tensile strength reduces than heating is preceding.
In contrast, the twisted wire of embodiment, owing to after twisted wire processing, carried out heat treatment in advance, thereby, can provide is not squeezed adds the influence of the thermal process that the heating that produces man-hour causes, at the coaxial cable that can not change aspect its tensile strength of the front and back of extrusion process and the resistance two.
Result according to table 7, the electrical characteristic of the coaxial cable of embodiment and the thicker original coaxial electric axis identical (for example, the electrical characteristic of the coaxial cable of the 43AWG of embodiment, 45AWG, 47AWG is identical with the electrical characteristic and the mechanical property of the coaxial cable of original 42 AWG, 44 AWG, 46 AWG with mechanical property) of wire size.Therefore, as 43 AWG, 45 AWG, 47 AWG,, when just can make coaxial cable realize carefully the footpathization, can also prevent the rapid deterioration of coaxial wire rod electrical characteristic by using the coaxial wire rod of odd number size.
Below, the evaluation result to the coaxial cable of embodiment 3-23, original routine 3-6 is described.

In addition, the various coaxial cables of embodiment 3-23, comparative example 3-24, original routine 3-6 electrostatic capacitance, attenuation and characteristic impedance have also been estimated.
The mensuration of electrostatic capacitance is to be connected with the LCR table between the inner conductor of the sample cable (coaxial cable) of 1m and the external conductor, to measure the electrostatic capacitance of 1KHz.In addition, with measuring with coaxial cable (lead-in wire), measured the attenuation of 10MHz with being connected with receiving terminal with the transmitting terminal of network analyzer between the inner conductor at the sample cable two ends of 1m and the external conductor.And, before the attenuation of measuring sample, proofread and correct the influence of measuring with coaxial cable (lead-in wire) to get rid of.In addition, characteristic impedance is to use network analyzer to measure numerical value at 10MHz.
Table 8, table 9 have been represented the evaluation result of these electrical characteristics and mechanical property.
Table 8 and table 9 are as follows:
*Flex life in the bracket before the expression heating
Figure A20061016877000481
*Flex life in the bracket before the expression heating

As shown in table 9, flex life with respect to the coaxial cable 20B of embodiment 3-5 (43 AWG) is more than 20900 times, the flex life of comparative example 3-9 (43 AWG) and original routine 3-6 (43 AWG) is respectively 19600 times, 12300 times, 18200 times, 20600 times, 12400 times, 18800 times, 9300 times, 16500 times, 12400 times, 11900 times, 12300 times, hence one can see that, the flex life of the coaxial cable of embodiment 3-5 is long, shows good flexural property.
In addition, the embodiment 6-23 of identical wire size and comparative example 13-24 compared also know that the coaxial cable of embodiment is longer with respect to its flex life of coaxial cable of comparative example, flexural property is better.
In addition, the result according to table 8, table 9 can confirm that the coaxial cable of the coaxial cable of embodiment 3-23 and comparative example and original example has relatively been kept identical electrostatic capacitance and characteristic impedance.Attenuation when being 10MHz about frequency can confirm that also the coaxial cable of embodiment compares with the original example of identical wire size and the coaxial cable of comparative example, has kept equal above attenuation characteristic.
Especially, though comparative example 8 is coaxial cables of 42 AWG, when comparing with regard to the coaxial cable of flex life and attenuation and embodiment 3-5, then can be evaluated as, embodiment 3-5 is longer aspect flex life, and equates substantially aspect attenuation.
In addition, with reference to table 7, when the tensile strength of twisted wire state and resistance are compared, then can be evaluated as, embodiment 3-5 is better aspect tensile strength, and about the same aspect resistance.
That is to say, according to present embodiment, according to requirement of client etc., even it is thinner that coaxial cable is made wire size, its electrical characteristic (center conductor resistance, attenuation) is also identical with the thicker comparative example of wire size, and flexural property (tensile strength) the comparative example higher coaxial cable thicker than wire size of coaxial wire rod can be provided.Therefore, when reducing the size of coaxial cable, can suppress the deterioration of electrical characteristic (resistance, attenuation) and mechanical property (flex life) as much as possible.
