Background technology:
In recent years, along with the raising of product design level, the electronic products such as mobile phone, computer are the little future development towards volume all, and the microminiaturization of loud speaker has also been proposed to harsh requirement.After the loud speaker volume reduces, the coil wire diameter is corresponding dwindling also, and conductor resistance increases, and in use can produce very large heat, so the thermal endurance class of conductor coils insulating material is required also improving constantly.Ultra-fine conductor coils not only will have good electrical property, mechanical performance, chemical property and adapt to outside the required anti-processing characteristics of High-Speed Automatic coiling, mechanical rule, also good thermal endurance must be arranged.In recent years, although domestic also at the positive ultra-fine conductor coils of hot melt self-adhering of the high thermal endurance class of development, current technical merit is compared with Foreign Advanced Lerel or there is a big difference.The ultra-fine conductor coils of hot melt self-adhering of domestic required high thermal endurance class is dependence on import basically.
The heat resisting temperature of home products hot melt self-adhering coil, generally at 130 ℃ ~ 150 ℃, is used coil because heat up and there will be the problem of distortion, fracture, makes the coil poor electric conductivity, thereby has reduced the quality of product.
The utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, provides a kind of high thermal endurance class hot melt self-adhering ultra-fine conductor coils, as a kind of exoskeletal coil, is widely used on the loudspeaker assembly of the electronic products such as television set, sound equipment, mobile phone.
Technology solution of the present utility model is as follows:
The ultra-fine conductor coils of a kind of high thermal endurance class hot melt self-adhering, comprise coil, and described coil is entwined in a spiral manner by the single conductor wire rod has inside and outside two-layer exoskeletal coil; Described single conductor wire rod is comprised of center conductor, the first insulating barrier and the second insulating barrier, and the first insulating barrier is coated on the center conductor outer surface, and the second insulating barrier is coated on the first insulating barrier outer surface; Described center conductor is the Kufil round conductor, and the first insulating barrier is the polyurethane enamelled coating, and the second insulating barrier is polyamide insulation enamelled coating.
As preferably, the diameter of described center conductor is 0.08mm.
As preferably, described the second insulating barrier adopts the mode that hot melt melts to fuse the outer surface at the first insulating barrier.
The beneficial effects of the utility model are:
The utility model improves coil insulation coating formula and coating processes, use a kind of special finish coatings material, adopt the automatic intelligent mode of spraying paint, Based Intelligent Control is evenly painted, and evaporates film-forming after levelling, realizes resistance to elevated temperatures, the high temperature resistant degree of hot melt self-adhering coil is reached more than 200 ℃, the problem of having avoided coil to be out of shape, to rupture because of heating up, make the coil electric conductivity more stable, improves the quality of products.
The utility model has also improved the hot melting cohesion performance of coil, be conducive to product processing, filled up the resistant to elevated temperatures blank of domestic hot melt wire, and this japanning can realize that product hot melt dissolution mechanism is shaped, changed the restriction of the molten mode of traditional alcohol, can realize full-automatic production by hot melting way, improve the technical merit that product is used.
Round conductor of the present utility model is to adopt to stretch, japanning, the curing technology high tensile that the 4% silver medal composition made is composited that combines with application technology, high power, high-intensity yellow gold material, it can bear the pressure of 420MPa, and fine copper can only bear the pressure of 280MPa, the high-strength complex film wire rod of being made by the yellow gold material, its pulling force can reach 190CN, and the pull-off force of industry product is only 130CN at present, the pull-off force of this product is higher than industry product 38%, therefore outage is low, high-strength complex film wire rod can bear the power of 2W simultaneously, the high-power characteristics of fine degree have been realized, leading position in hollow voice coil loudspeaker voice coil.
The utility model anti-bending strength is high, can curvedly to 960 times, just can rupture, and its anti-bending strength is quite high.
The utility model the is high temperature resistant ultra-fine conductor coils of hot melt self-adhesion, as a kind of exoskeletal coil, is widely used on the loudspeaker assembly of the electronic products such as television set, sound equipment, mobile phone.
