Abstract
The utility model provides a long-life compound electric soldering bit, for a head fixedly connected with anti solder tin erosion layer at the copper base member, connect in the periphery on copper base member and anti solder tin erosion layer and be fixed with the antioxidation layer, the utility model discloses improved anti solder tin erosion, high temperature oxidation's ability greatly, showing and prolonged life, excellent performance.
Description
The utility model relates to a kind of electrician's instrument.
Electric iron is electrician, electronics, the most frequently used instrument of electrical apparatus industry, and the consumption of electric soldering bit is very big.For a long time, electric soldering bit adopts red copper to make always, this is because copper has very high thermal conductivity, in metal, be only second to silver, but the copper electric soldering bit is in actual use owing to the etch of high-temperature oxydation and liquid scolding tin has had a strong impact on its service life, can only use a few hours on production line as copper 40W electric soldering bit, its head will be lost efficacy by the serious etch of liquid scolding tin, in this case, domestic electric iron manufacturer electroplates one deck nickel or nickel alloy one after another on the copper electric soldering bit, prolong 2-3 doubly than single copper electric iron its service life, but still differ greatly with external like product, though the electric soldering bit of external like product structurally also adopts the mode of electroplating layer of metal on the above-mentioned domestic electric soldering bit, with homemade different be that its top layer is the iron plating layer of thick 1-2mm.Modern Electronic electrical equipment manufacturer develops rapidly in recent years, life-span, the lower use of homemade electric soldering bit on these manufacturer production lines seriously influenced the production efficiency of whole production line and even whole factory, the electric soldering bit of online use sometimes was as long as one lost efficacy, and whole production line will be stopped.With regard to the whole nation, this situation can cause a large amount of wastes of copper material; The numerous and confused import electric soldering bit of numerous producers also causes the waste of national foreign exchange resources and the increase of production cost.
The purpose of the utility model aims to provide the good thermal conductivity of a kind of simple in structure, long service life, assurance, improves the compound electric soldering bit of long-life of oxidation-resistance property.
Technical solution of the present utility model is: compound electric soldering bit of this long-life is for being fixedly connected with the anti-scolding tin etch of one deck layer at the head of copper matrix, is fixedly connected with one deck anti oxidation layer in the periphery of copper matrix and anti-scolding tin etch layer.
The utility model is compared with prior art, both guaranteed the thermal conductive resin of electric soldering bit, the anti-scolding tin etch layer that the head of electric soldering bit is connected and fixed has greatly improved the anti-scolding tin etch of electric soldering bit ability, significant prolongation service life, the periphery anti oxidation layer of whole electric soldering bit has also improved oxidation-resistance property, avoided the phenomenon of copper electric soldering bit oxidation in use decortication, made it function admirable, the life-span prolongs greatly.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model example structure schematic diagram;
Be described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the utility model is divided into three parts, first is a central module, it is the matrix 1 that fine copper is made, second portion is the overcoat of head, promptly anti-scolding tin etch layer 2, and third part is the overcoat that is covered on the whole electric soldering bit, be anti oxidation layer 3, the annexation between them is such; Anti-scolding tin etch layer 2 is to glued joint or to electroplate or the mode of welding obtains and the fixedlying connected of copper matrix 1, anti-scolding tin etch layer 2 is iron or nickel or silicon or aluminium or their alloy, its thickness range is 0.05-3mm, anti oxidation layer 3 is to electroplate or chemistry expands the method for oozing and obtains and the fixedlying connected of copper matrix 1, anti-scolding tin etch layer 2 periphery, anti oxidation layer 3 its compositions are nickel or chromium or zinc or aluminium or their alloy, and thickness is 0.005-0.2mm.
Copper matrix 1 its head of Fig. 2 is common ramp structure, and with the two kind shapes of sharp structure for using always shown in Figure 1, the annexation between anti-scolding tin etch layer 2, anti oxidation layer 3 and the copper matrix 1, material composition illustrates identical with aforesaid Fig. 1.
Claims (4)
