Abstract
The invention discloses a wire wound resistor of a spark plug cap. Metal caps (2) are sleeved at two ends of a ceramic rod (1); an alloy wire (3) is wound around the rod body of the ceramic rod (1); each end of the alloy wire (3) is welded on the corresponding metal cap (2); a small section of the alloy wire (3), close to each end, is bonded and fixed on the corresponding metal cap (2) through a silver copper slurry layer (4); the outer side of the opening end of each metal cap (2) and the rod body of the ceramic rod (1), between the two metal caps (2), are coated with a high temperature paint coating (5) which covers the alloy wire (3) and the silver copper slurry layer (4). According to the wire wound resistor, as the alloy wire and the metal caps are bonded through the silver copper slurry layer, on the premise that the alloy wire is not damaged, the connection reliability between the alloy wire and the metal caps is guaranteed; thus the conduction performance of the wire wound resistor is effectively improved; the wire wound resistor has the characteristics of ingenious design, simple structure, easiness in modification and low modification cost.
Description
Technical field
The present invention relates to a kind of spark plug cap parts, the wire resistor particularly on spark plug cap.
Background technology
Spark plug cap is the vitals on automobile, motorcycle and logical machine, and for connecting high-voltage line and spark plug, its quality, directly affects the startability of automobile, motorcycle or logical machine.Wire resistor is arranged in spark plug cap, and be made up of porcelain rod, alloy wire and metal cap etc., press-fit metal cap at the two ends of porcelain rod, alloy wire is wound on porcelain rod, and the two ends of alloy wire are welded on two metal caps respectively.Welding procedure between alloy wire and metal cap is spot welding, and easily produce dry joint or rosin joint because point is welded in frequent production process, in use, spot welding place between alloy wire and metal cap easily comes off such wire resistor, causes wire resistor not conducting.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide the good spark plug cap wire resistor of a kind of conduction.
Technical solution of the present invention is as follows: a kind of spark plug cap wire resistor, metal cap (2) is all set with at the two ends of porcelain rod (1), the rod of porcelain rod (1) is wound around alloy wire (3) with it, the two ends of this alloy wire (3) and two metal cap (2) one_to_one corresponding, and the termination of alloy wire (3) is welded on corresponding metal cap (2), its key is: described alloy wire (3) is adhesively fixed on metal cap (2) near a bit of of termination by silver-bearing copper pulp layer (4), high temperature oil enamelled coating (5) is coated with it in the outside of described metal cap (2) opening end and porcelain rod (1) rod be positioned between two metal caps (2), this high temperature oil enamelled coating (5) by alloy wire (3) and silver-bearing copper pulp layer (4) coated.
The present invention starches near end coating silver-bearing copper at alloy wire, alloy wire is fixed on metal cap by the adhesive property starched by silver-bearing copper, and alloy wire is injury-free, and the conductivity of silver-bearing copper slurry does not affect the contact conduction property between alloy wire and metal cap, to be connected firmly between such alloy wire and metal cap, reliably, can not occur to loosen or come off, effectively eliminate wire resistor and not conducting phenomenon occurs, ensure that constant product quality.Alloy wire termination and the spot welding between metal cap as together with aided process, play a part to locate alloy wire termination, so that 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 sealing, and steam etc. can be avoided to enter the conduction property affecting wire resistor in metal cap; Meanwhile, high temperature oil enamelled coating can also aesthetic appeal, makes wire resistor more attractive in appearance.
Described metal cap (2) is stamped to form by the chromium plate that 0.27-0.33mm is thick, more than utilizes the good ductility of chromium, and not only processing technology is simple, and production efficiency is high, and the structural strength of metal cap is good, not easily deforms or damages.
For the ease of processing, guarantee uniform production, the external annulus of each metal cap (2) opening end is coated with a circle silver-bearing copper pulp layer (4).
Beneficial effect: the present invention is by silver-bearing copper slurry bonding alloy line and metal cap, can under the prerequisite not damaging alloy wire, guarantee the fixing be connected between alloy wire with metal cap, thus effectively improve the conduction property of wire resistor, there is the features such as design is ingenious, structure simple, transformation is easy, improvement cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, the present invention has porcelain rod 1, and this porcelain rod 1 is column structure.Be symmetrical arranged metal cap 2 at the two ends of porcelain rod 1, metal cap 2 is preferably stamped to form by the chromium plate that 0.27-0.33mm is thick, and is fixedly set on porcelain rod 1 by press-fiting.Be wound around alloy wire 3 with it at the rod of porcelain rod 1, the canoe of alloy wire 3 is same as the prior art, and therefore not to repeat here.The two ends of alloy wire 3 and two metal cap 2 one_to_one corresponding, and the termination of alloy wire 3 is by the metal cap 2 of spot-welded in correspondence.The external annulus of each metal cap 2 opening end is coated with a circle silver-bearing copper pulp layer 4, and alloy wire 3 is adhesively fixed on metal cap 2 by silver-bearing copper pulp layer 4 near a bit of of termination.In the outside of metal cap 2 opening end and porcelain rod 1, the rod between two metal caps 2 is coated with high temperature oil enamelled coating 5 with it, and this high temperature oil enamelled coating 5 is by coated for the silver-bearing copper pulp layer 4 on all alloy wires 3 and both sides.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection range of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
