Embodiment
With reference to the accompanying drawings, the execution mode with regard to band electronic parts of the present invention describes.Fig. 1 illustrates first execution mode of band electronic parts of the present invention.This band electronic parts 1 is to have square sheet electronic component 2 and band electronic parts two metal line 3, that be ladder shape, and sheet electronic component 2 has terminal electrode, and terminal electrode is formed on the two ends of the element of cuboid substantially; The maintaining part 4 of two metal line 8 separates certain interval and forms and be connected with the terminal electrode of above-mentioned sheet electronic component 2.The terminal electrode of sheet electronic component 2 and maintaining part 4 are fixing by the electric conducting material (not having diagram) of scolder or electroconductive resin etc.Need to prove, with the interval between the maintaining part 4 of metal wire 3, be that the lead-in wire that can form Len req in the time will being divided into single parts with electronic parts on electronic unit is set at interval between the sheet electronic component 2 for.
Sheet electronic component 2 is the parts that are formed with terminal electrode on the two ends of rectangular member are relative two faces, and this sheet electronic component 2 can be lamination electronic unit, chip resistor of lamination capacitor, laminated coil, laminated heat sensitive resistor and lamination variable resistance etc. etc.Terminal electrode also can be formed the face adjacent with its formation face that extend to.The size of sheet electronic component 2 has 1.6mm * 0.8mm, 1.0mm * 0.5mm and 0.6mm * 0.3mm, 0.4mm * 0.2mm etc., and this first execution mode is suitable for the above square sheet electronic component of 1.0mm * 0.5mm most.
As shown in Figure 2, the S shape that forms by the bending machining to metal wire 3 adds the Ministry of worker 4 ' with certain being spaced.This adds the Ministry of worker 4 ' and is formed the maintaining part 4 that takes the shape of the letter U substantially at sweep BL place by further bending.Utilize this maintaining part 4 that bends to the cardinal principle U-shaped to clamp and keep the terminal electrode of sheet electronic component 2.The thickness of metal wire 3 has 0.2mm φ～1.0mm φ etc., but for the first-class purposes of the terminal of bobbin that is wound on intermediate frequency transformer or iron core, is preferably below the 0.3mm φ.And the shape that adds the Ministry of worker 4 ' is not limited to S shape, can be 8 fonts or swirl shape etc. also, so long as the shape that can form by bending machining gets final product.
Below describe with regard to second execution mode of band electronic parts of the present invention.The band electronic parts 11 shown in Figure 3 and the difference of first execution mode are that maintaining part 14 is not by bending process but be processed to form by flattening.When sheet electronic component 12 is little during to 0.6mm * 0.3mm or 0.4mm * 0.2mm, if metal wire 13 for example is the thickness of 0.2mm φ, then the thickness of the size of sheet electronic component and metal wire is approaching.Therefore, more favourable by flattening processing than forming maintaining part 14 by bending process.
As shown in Figure 4, metal wire 13 pass through flatten processing form add the Ministry of worker 14 ' with certain being spaced.This adds the Ministry of worker 14 ' and is further bent at folding line BL place and form the maintaining part 14 that takes the shape of the letter U substantially.Utilize this to be bent into the terminal electrode that sheet electronic component 12 was clamped and kept to the maintaining part 14 that takes the shape of the letter U substantially.
This adds the Ministry of worker 14 ' is flattened it to form by for example beaing metal wire 13 with drift etc.Therefore, the side depression that mostly occurs of contact drift.In order fully to be clamped and kept the effect of sheet electronic component 12, will make the length lengthening of bending part, therefore preferably will add the Ministry of worker 14 ' bends to form maintaining part 14, so that the length of available bending part is longer to the rightabout that contacts a side with drift.Therefore, as shown in Figure 3, the opposition side that preferably adds a side that contacts with drift of the Ministry of worker 14 ' corresponding to the terminal electrode of sheet electronic component 12 to maintenance bends to form maintaining part 14, so that keep the terminal electrode of sheet electronic component 12.
Need to prove, form under the situation of face at the size of the face of the contact drift that adds the Ministry of worker 14 ' terminal electrode greater than sheet electronic component 12, band electronic parts 11 ' as shown in Figure 5 like that, to add the Ministry of worker 14 ' to the face lateral buckling that contacts with drift to form maintaining part 14, utilize bending part and recess to keep getting final product.In this case, owing to form the hold mode identical, so clamp and keep the effect of sheet electronic component 12 higher with crown cap.In addition, process is flattened the maintaining part 14 of processing owing to the thickness of its thickness less than metal wire 13, thus the intensity reduction, but owing to can reinforce by the electric conducting material (do not have and illustrate) of scolder or electroconductive resin etc., so do not have problem.
Following according to Fig. 6, to be example with the band electronic parts of first execution mode describe with regard to the manufacture method of band electronic parts of the present invention.At first, prepare two metal line 3 (for example 0.2mm φ).Respectively this two metal line 3 is carried out bending process, add the Ministry of worker 4 ' with what certain interval formed S shape.Then, this two metal line 3 is arranged in parallel and makes add the Ministry of worker 4 ' toward each other.
Then, as shown in Figure 6, the terminal electrode of sheet electronic component 2 (for example being the lamination capacitor of 1.6mm * 0.8mm) is contacted with the Ministry of worker 4 ' that respectively adds of two metal line 3.Afterwards, the terminal electrode that makes sheet electronic component 2 by pressing component PT will add the Ministry of worker 4 ' and be bent into U-shaped substantially with adding the Ministry of worker's 4 ' crimping, thereby will form maintaining part 4 to seize on both sides by the arms.This pressing component PT has the parts that make the shape that adds the Ministry of worker's 4 ' bending, for example is the parts with the groove that takes the shape of the letter U substantially, also can be elastomeric plates such as rubber.In addition, also can be in advance form substantially U-shaped and form maintaining part 4 adding the Ministry of worker 4 ', then with the terminal electrode crimping of sheet electronic component 2 to seize on both sides by the arms.
Utilize 5 pairs of maintaining parts 4 of scolder and terminal electrode to weld then.So just, can access the band electronic parts of ladder shape.
More than be illustrated with regard to band electronic parts of the present invention and manufacture method thereof, but as long as within the scope of the invention, the kind of electronic unit, the material of metal wire etc. can be carried out various changes.
