Abstract

The utility model discloses an improved generation paster transformer, including the transformer body, the both ends of transformer body be provided with elementary paster pin and secondary paster pin respectively and expose in the transformer body, twine primary and secondary coil on the transformer body, primary and secondary coil include coil body who comprises single enameled wire and the two coil ends that are formed by many enameled wire transposition, wherein, many are the odd number root, and the diameter size of enameled wire is 0.03mm~0.10mm, the coil end is through soaking tin welding on the paster pin that corresponds. Carry out the tie lines after this novel paster transformer adopts the fine rule of stranded to strand, can not take place the broken string in the in -process end that winds the line, improved wire -wound yield, it is few to produce the line tail during automatic machine tie lines, need not artifical the pruning, and production efficiency is high.

Description

A kind of modified model SMD transformer

Technical field

This utility model relates to transformer technology field, particularly a kind of modified model SMD transformer.

Background technology

And making rapid progress along with electronic technology, be frequently used in prior art is SMD transformer.And prior art In SMD transformer, use the coil of sub-thread about 0.03mm～0.08mm to be wrapped on reel, the termination of coil lead-in wire is straight Binder, on the pin of transformer base, so has the disadvantage that

One is, owing to carrying out tie lines with the enamel-covered wire of the 0.03～about 0.08mm of sub-thread with pin, is wound around at enamel-covered wire Easily break during pin, cause whole coil to be scrapped.

Two are, are easily generated line tail when automatic machinery tie lines, need manually to prune.

Three are, when immersed solder, during Pb-free coating immersed solder, stannum can produce certain copper erosion to enamel-covered wire, 0.03mm's～0.08mm Enamel-covered wire makes diameter reduce, if immersed solder time and temperature control improper the most directly blow lead-in wire because copper erosion;Immersed solder copper loses The lead-in wire that rear diameter diminishes, is manufacturing or during client's use, can be because easily breaking when other article encounter lead-in wire Line, causes product failure.

Utility model content

The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of modified model paster Transformator.

For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of modified model SMD transformer, Including transformer body, the two ends of described transformer body are respectively arranged with primary paster pin and secondary paster pin and outer It is exposed to described transformer body, described transformer body is wrapped primary coil and secondary coil；Described primary coil is with secondary Level coil includes the coil body that is made up of single enamel-covered wire and by stranded two coil ends of many enamel-covered wires；Wherein, Described many is odd number root, and the diameter dimension of described enamel-covered wire is 0.03mm～0.10mm；Described coil end is by leaching Soldering is connected on the paster pin of correspondence.

In technique scheme, described transformer body includes reel for being wound around coil and is arranged at about reel two Holding as the base supporting and installing paster pin, reel transverse strands is located between the base of the left and right sides, and the side of reel hangs Empty.

In technique scheme, described base includes upper bed-plate and lower bottom base, described primary paster pin and secondary paster Pin correspondence respectively is installed in described upper bed-plate and lower bottom base.

In technique scheme, the upper surface of described upper bed-plate is provided with the mounting groove of depression, and U-shaped described paster draws Foot inserts from this mounting groove and stretches out from the bottom surface of lower bottom base, and the two ends pin of paster pin is parallel, and phase on lower bottom base The breach of arch (bridge) type is set between adjacent paster pin.

The beneficial effects of the utility model are: this Novel patch transformator use multiply fine rule stranded after carry out tie lines, In winding process, will not break in termination, improves the yield rate of coiling；Line tail is produced few, nothing during automatic machinery tie lines Need to manually prune, production efficiency is high；And when to SMD transformer coil immersed solder, because termination is that multiply fine rule is stranded, termination is straight Footpath is more than 3 times of original sub-thread diameter, thus the diameter reduction scope that copper erosion causes when Pb-free solder is little, it is to avoid immersed solder is broken Line is bad and avoids the broken string caused in producing and using, and product reliability improves, and SMD transformer is long for service life.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail.

As shown in Figure 1-2, a kind of modified model SMD transformer, including transformer body 1, the two of described transformer body 1 End is respectively arranged with primary paster pin 2 and secondary paster pin 2 and exposes to described transformer body 1, described transformator Primary coil and secondary coil it is wrapped on body 1；Described primary coil and secondary coil include being made up of single enamel-covered wire 4 Coil body 9 and by stranded two coil ends 3 of many enamel-covered wires 4；Wherein, described many is odd number root, and described The diameter dimension of enamel-covered wire 4 is 0.03mm～0.10mm；Single enamel-covered wire 4 can be gone back slightly than original, improves stability And reliability；Described coil end 3 is welded on the paster pin 2 of correspondence by wicking.

Wherein, described transformer body 1 includes the reel 5 for being wound around coil and is arranged at reel about 5 two ends conduct Supporting and install the base 6 of paster pin 2, reel 5 transverse strands is located between the base 6 of the left and right sides, and the side of reel 5 hangs Empty.Improve the structural reliability of transformator.

Wherein, described base 6 includes integrated upper bed-plate 6 and lower bottom base 6, described primary paster pin 2 and secondary Paster pin 2 correspondence respectively is installed in described upper bed-plate 6 and lower bottom base 6.

Wherein, the upper surface of described upper bed-plate 6 is provided with the mounting groove 7 of depression, and U-shaped described paster pin 2 is from this Mounting groove 7 inserts and stretches out from the bottom surface of lower bottom base 6, and the two ends pin of paster pin 2 is parallel, and adjacent on lower bottom base 6 The breach 8 of arch (bridge) type is set between paster pin 2.Improve reliability of structure.

Above embodiment simply indicates that rather than limits this utility model, therefore all according to this utility model patent application The equivalence that method described in scope is done changes or modifies, and is all included in this utility model patent claim.
