3) at the weld coating silver-bearing copper slurry of alloy wire (3) with metal cap (2), silver-bearing copper slurry forms silver-bearing copper pulp layer (4) after solidifying, and makes alloy wire (3) be adhesively fixed on metal cap (2) by silver-bearing copper pulp layer (4) near a bit of of termination；
4) it is positioned at the rod between two metal caps (2) in the outside of metal cap (2) opening end and porcelain rod (1) and is coated with high temperature paint, it is then fed into oven for baking, make high temperature paint curing, forming high temperature oil enamelled coating (5), alloy wire (3) and silver-bearing copper pulp layer (4) are coated with by this high temperature oil enamelled coating (5).
Present invention process is simple, and operation is few, be conducive to batch production meanwhile, it is capable to guarantee quality and the uniform production of product.The present invention is coated with silver-bearing copper at alloy wire near end and starches, alloy wire is fixed on metal cap by the adhesive property starched by silver-bearing copper, and alloy wire is injury-free, and the electric conductivity of silver-bearing copper slurry does not affect and contacts conduction property between alloy wire with metal cap, it is connected firmly between such alloy wire and metal cap, reliably, will not occur to loosen or come off, effectively eliminate wire resistor and be not turned on phenomenon, it is ensured that constant product quality.Alloy wire termination and the spot welding between metal cap as together with aided process, play the effect of alloy wire termination, location, in order to alloy wire coating silver-bearing copper slurry is fixed with metal cap.The opening end of metal cap is hidden in high temperature oil enamelled coating, and high temperature oil enamelled coating plays the effect of sealing, it is possible to avoid steam etc. to enter the conduction property affecting wire resistor in metal cap；Meanwhile, high temperature oil enamelled coating can also aesthetic appeal, make wire resistor more attractive.
Described metal cap (2) is stamped to form by the chromium plate that 0.27-0.33mm is thick.The good ductility of chromium utilized above, not only processing technique is simple, and production efficiency is high, and the structural strength of metal cap is good, is not susceptible to deformation or damages.
In order to improve efficiency, silver-bearing copper slurry is made to solidify as early as possible, as preferably, step 3) in, after the weld coating silver-bearing copper slurry of alloy wire (3) and metal cap (2), send into oven for baking, baking time is 25-35 minute, and baking temperature is 65-75 DEG C, makes silver-bearing copper slurry solidify.
In order to make high temperature oil enamelled coating have enough thickness, to protect alloy wire, make high temperature paint solidify as early as possible, step 4 simultaneously) three high temperature paint of middle coating；The temperature sending into oven for baking is 195-205 DEG C, and baking time is 1.9-2.1 hour.
Beneficial effect: the present invention is by silver-bearing copper slurry bonding alloy line and metal cap, can under the premise not damaging alloy wire, guarantee the fixing being connected between alloy wire with metal cap, thus being effectively increased the conduction property of wire resistor, the feature such as there is ingenious, the simple in construction of design, transformation is easy, improvement cost is low.
