The invention not only has strong conductive performance and better mechanical property, but also has higher shield effect and strong anti-jamming capability.
Description
Technical field
The present invention relates to a kind of copper litz wire, relate in particular to a kind of tin-coated copper alloy litzendraht wire, specifically be applicable to electric device and electronic electric equipment or element wiring usefulness such as electric device, switching circuit, electric furnace and storage battery.
Background technology
The copper litz wire of Shi Yonging is generally TR type annealed copper wire in the market, and this kind copper litz wire is used for litzendraht wire with a large amount of copper wires and makes shielding usefulness, though have shield effectiveness preferably, has consumed a large amount of copper products, and production cost is very high.
The Chinese patent publication number is CN1822241A, the patent of invention that open day is on August 23rd, 2006 discloses a kind of tin-copper plating aluminium-magnesium cladded woven wire, described tin-copper plating aluminium-magnesium cladded woven wire comprises Al-Mg alloy core, be coated with the copper layer on the Al-Mg alloy core, the copper layer is electroplate with the tin layer outward, and the sectional area ratio of described copper layer and Al-Mg alloy core is 2: 23~1: 9.Though this invention has alleviated weight when not influencing shield effectiveness, saved copper product, and strengthened the solderability of litzendraht wire, its shield effectiveness is still not high, and electric conductivity is not strong, and mechanical performance is also relatively poor, frangibility during use.
Summary of the invention
The objective of the invention is to overcome that the shield effectiveness that exists in the prior art is not high, electric conductivity is strong, relatively poor defective and the problem of mechanical performance, provides that a kind of shield effectiveness is higher, electric conductivity is strong, the tin-coated copper alloy litzendraht wire of better mechanical property.
For realizing above purpose, technical solution of the present invention is: a kind of tin-coated copper alloy litzendraht wire, comprise inner core lead, outer conducting layer and tin coating, and the external packets of described inner core lead is covered with outer conducting layer, and the external packets of outer conducting layer is covered with tin coating; Described inner core lead is made of the inner core main line and the inner core by-pass of interlacing, and the quantity of inner core by-pass is at least two; Be provided with screen between the outside of described outer conducting layer and the tin coating.
The manufactured materials of described screen is epoxy resin, polyvinyl chloride or PET resin.
The interlacing mode of described inner core main line and inner core by-pass is a cross skewed crossing weaving manner.
The size of crossing angle is 60 degree in the described cross skewed crossing weaving manner.
The manufactured materials of described inner core main line is a Kufil, and described inner core by-pass constitutes by the albronze line is stranded, and the quantity of albronze line is at least two.
The mass percent of silver is 0.01%-0.15% in the described Kufil.
The quantity of described albronze line is three, and is twisted into pigtail shape mutually.
Compared with prior art, beneficial effect of the present invention is:
1. owing to the inner core lead in a kind of tin-coated copper alloy of the present invention litzendraht wire is made of inner core main line and inner core by-pass, the manufactured materials of inner core main line is a Kufil, the manufactured materials of inner core by-pass is the albronze line, the manufactured materials of inner core main line, inner core by-pass has determined its favorable conductive effect, and because inner core main line and the mutual interlacing of inner core by-pass, the inner core by-pass constitutes by the albronze line is stranded, and this design makes the present invention have the favorable mechanical performance, toughness is stronger.So electric conductivity of the present invention is strong, better mechanical property.
2. owing to be coated with outer conducting layer, screen and tin coating successively in the outside of inner core lead in a kind of tin-coated copper alloy of the present invention litzendraht wire, and the manufactured materials of outer conducting layer is copper or albronze, the manufactured materials of screen is epoxy resin, polyvinyl chloride or PET resin, this design makes the present invention not only have good shield effectiveness, antijamming capability is stronger, and welding easily, easy to use.Therefore not only shield effectiveness height, antijamming capability are strong in the present invention, and easily welding, and be easy to use.
Description of drawings
