Abstract
The utility model relates to a plastic hot sticking coil, which is mainly composed of conductive wires with thermoplastic insulating layers. The shape of the utility model can be a circular sheet shape, or a rectangular sheet shape, or a circular barrel shape, or a rectangular barrel shape, or a rectangular column cross section shape, or a circular column cross section shape, or other proper shapes. After the coil is formed, the core wires of the conductive wires are conducted to heat to soften the plastic insulating layers to be automatically stuck for shaping. The utility model has the advantages of simple processing technology, no need of coil bobbin, no need of package, no need of bundle, no need of adhesive, high production efficiency, and low cost. The utility model is mainly used in the field of radio electronic technology, such as anti-theft devices, the degaussing coils of displayers, etc.
Description
The utility model relates to a kind of heating self-adhesion coil.
At present, airport, the used harmonic high frequency vibration shape alarm in supermarket, its resonance coil generally has two kinds.A kind of is to carve the involute groove in the alarm plastic casing, lead is embedded in relies on the shell location in the groove then, forms involute shape coil; Another kind is with enamelled wire coiled disk shape air core coil, through adhesive curing, forms coil.All there is the mass-production process complexity in these two kinds of resonance coils, the cycle is long, cost is high, need problems such as specialized apparatus aborning.
At electronic technology field, the anti-magnetized coil of some inductance coils, solenoid, radio frequency choke, oscillator coil, colour TV and display etc., generally use the enamelled wire coiling, need coil rack for gaining in strength or add the thick line footpath, the anti-magnetized coil of colour TV and display then needs the bag bundle to handle complex process.
It is the lead loop of insulating layer material with the thermoplastics that the purpose of this utility model provides a kind of, and the energising heating can once be finalized the design behind this coil coiled, need not coil rack, need not wrap bundle and handle, operation is simple, be suitable for producing in batches, the production efficiency height, equipment investment is few.
Plastic hot coil stuck described in the utility model mainly is made up of the lead of band thermoplastics insulating barrier.The heart yearn of lead can be bare copper wire, tinned wird, silver-coated copper wire, enamelled wire or other metal wires, and the thermoplastics insulating barrier can be polyvinyl chloride, polyethylene, polypropylene or other thermoplastics.Coil shape can be disk shape, rectangle sheet, circular tubbiness, rectangle tubbiness, rectangular column cross section shape, circular columns cross section shape.Used metal core wire directly through be 0.2 to 1.0 millimeter comparatively suitable, the applicable plastic thickness of insulating layer is 0.1 to 2.0 millimeter.
This plastic hot coil stuck, owing to adopted coiling, heating, self-adhesion once to finalize the design, thereby processing technology is simple, the production efficiency height, and the coil typing need not skeleton or the bag bundle is handled, and does not also need adhesive, has reduced production cost
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the profile of disk shape plastic hot coil stuck;
Fig. 2 is the profile of rectangle sheet plastic hot coil stuck;
Fig. 3 is the profile of round barrel shape plastic hot coil stuck;
Fig. 4 is the profile of rectangle tubbiness plastic hot coil stuck;
Fig. 5 is the profile of rectangular column cross section shape plastic hot coil stuck;
Fig. 6 is the profile of circular columns cross section shape plastic hot coil stuck.
Plastic hot coil stuck described in the utility model, its shape can be made disk shape 1, rectangle sheet 2, circular tubbiness 3, rectangle tubbiness 4, rectangular column cross section shape 5, circular columns cross section shape 6 or other suitable shape.Its structure mainly is made up of the lead of band thermoplastics insulating barrier.According to different purposes, the heart yearn of lead can be that diameter is 0.2 to 1.0 millimeter bare copper wire, zinc-plated or silver-coated copper wire, enamelled wire or other metal wire, also the resistive conductor two-wire can be unrolled into noninductive resistor, and at this moment heart yearn is to satisfy the resistance wire that the rate of attacking requires; The thermoplastics insulating barrier can be that thickness is 0.1 to 2.0 millimeter polyvinyl chloride, polyethylene, polypropylene or other thermoplastics, as modified thermoplastic.In a word, this lead that has insulating barrier, can be from the market or manufacturer buy, as single semi-finished product heart yearn of moulding copper cash, telecommunication cable etc.During coiling,, select different moulds for use, thereby different coilings and electrical heating process are arranged according to the difformity coil.Insulation when heating for making can be selected thermal and insulating performance is good, high temperature resistant and have certain intensity bakelite (phenolic resins), fiberglass (epoxy resin), polysulfone plastic or pottery etc., as mold materials.When carrying out heart yearn electric heating typing, according to the resistance characteristic of heart yearn material, determine that the current density that heart yearn passes through is 85 to 250 amperes every square millimeter, the current density that resistive conductor passes through is then littler.
Plastic hot coil stuck described in the utility model, its shape except above-mentioned points, other suitable shape can also be arranged, as straw hat shape, cup-shaped, polygon or other polymorphic structure, the thickness of coil, size, the diameter of heart yearn, the thickness of plastic insulating layer etc., different sizes can be arranged, but all belong to design concept of the present utility model.
Claims (2)
1, a kind of plastic hot coil stuck, mainly form by the lead of band thermoplastics insulating barrier, the heart yearn of lead can be bare copper wire, tinned wird, silver-coated copper wire, enamelled wire or other metal wires, the thermoplastics insulating barrier can be polyvinyl chloride, polyethylene, polypropylene or other thermoplastics, it is characterized in that: the shape behind the plastic hot coil stuck turn-to-turn self-adhesion can be disk shape [1], rectangle sheet [2], circular tubbiness [3], rectangle tubbiness [4], rectangular column cross section shape [5], circular columns cross section shape [6].
