Description

Electronic component

[technical field]

The utility model relates to a kind of electronic component, the electronic component that the especially a kind of SMT of employing mode is connected with circuit board.

[background technology]

When electronic component adopts the SMT mode to be connected with circuit board, be generally earlier and apply one deck bonding agent at the electronic component weld part, then the tin ball is bonded on the weld part by bonding agent, thereby the electronic component placement that then this adhesion is had the tin ball is at high temperature toasted and is made the metal molten in the bonding agent firmly be welded in the tin ball on the weld part, the defective of the prior art is: electrically contact with circuit board for guaranteeing each weld part, above-mentioned tin ball needs to guarantee quite high flatness after being soldered on the weld part, therefore higher to the uniformity requirement of tin ball shape, and in the production scene storage of this tin ball with transport all comparatively time-consuming, therefore from the production of tin ball and the production actual state of electronic component, the production of electronic components cost of above-mentioned employing tin ball connected mode is higher.And under certain tin amount situation, tin club takies certain height and width, and for the situation that the conducting terminal spacing is more and more littler or the electronic component height is more and more littler of present electronic component, the use of tin ball has seriously restricted the development of electronic component.So, press for design at present and produce a kind of novel, highly less or the conducting terminal spacing is less and can guarantee the electronic component of good welds effect.

[summary of the invention]

The purpose of this utility model is to provide a kind of and has less conducting terminal spacing or than low height and can guarantee the electronic component of good welds effect.

Electronic component provided by the utility model comprises insulating body and is fixed in plurality of conductive terminals on the insulating body, the corresponding conducting terminal of this electronic component further is provided with some scolders, and it is non-spherical that this scolder is, thereby can make electronic component have less conducting terminal spacing or than low height and can guarantee the good welds effect.

[embodiment]

Please refer to Fig. 1, shown in Figure 2, implement electronic component of the present utility model and comprise insulating body 10, be fixed in plurality of conductive terminals 20 and scolder 30 on the insulating body 10, wherein insulating body is divided into two parts 12 up and down, 14, conducting terminal 20 parts are inserted in the insulating body 10, another part exposes insulating body 10 outsides, and its end is provided with roughly horizontal weld part 22, this weld part 22 fits with the upper surface of insulating body 10 lower parts 14, with the weld part 22 corresponding holes 16 that are provided with, scolder 30 promptly is embedded in the hole 16 on insulating body 10 lower parts 14.This scolder 30 is square, and its width is less but highly bigger, guarantees firmly to weld with circuit board (not drawing among the figure) thereby have enough tin amounts, and because this bead width is less, compare with existing tin ball, can have less spacing, can guarantee that conducting terminal is closely aligned.Certainly, also can scolder 30 ' is made than big width and than low height (as shown in Figure 3), thereby this electronic component can have than low height under certain tin amount condition, to adapt to the compact development trend of electronic product as required.

The conducting terminal 20 ' of this electronic component can be made into other different shape, as its upper surface (as shown in Figure 4) that is exposed to the part approximate horizontal of insulating body 10 ' outside and fits in insulating body 10 ' lower part, can produce above-mentioned effect equally.As Fig. 5, shown in Figure 6, the scolder of this electronic component can plant in the hole in the insulating body lower part by following method: 1) provide a tabular scolder 40; 2) provide a servicing unit 42, wherein this servicing unit 42 offers some through holes 44; 3) insulating body 48 that will assemble conducting terminal 46 places servicing unit 42 belows, wherein insulating body 48 bottoms up, then tabular scolder 40 is positioned over opposite side surface on the servicing unit 42, utilize decompressor 50 to make the scolder of reservation shape pass servicing unit through hole 44, be mounted in the insulating body hole 52, and contact with conducting terminal 46.By the method, can guarantee that the bottom of scolder is in the same plane, thus the welding effect of raising and circuit board.Be preferably between decompressor 50 and the scolder 40 and add stripper plate 54, to make things convenient for punch process.

Certainly, the utility model electronic component is embodied as many different forms, be not limited to conducting terminal weld part basal surface as scolder and contact, also can make a side contacts (as shown in Figure 7) of scolder 60 and conducting terminal 62, or scolder 70 is embedded in the through hole 76 that conducting terminal 72 weld parts 74 are provided with (as shown in Figure 8), or establish a hole 82 in scolder 80 central authorities, and conducting terminal 84 ends plug and are fixed in this scolder 80 (as shown in Figure 9), or be coated with adhesion 92 at conducting terminal weld part 90 basal surfaces, scolder 94 is adhered to (as shown in figure 10) on the weld part 90, or establish a through hole 106 at conducting terminal 102 weld parts 104 that are attached at insulating body 100 bottom surfaces, so that scolder 108 is embedded at (as shown in figure 11) in the through hole 106, in the above-described embodiments, insulating body 100 ' basal surface also can corresponding scolder 108 ' inside recessed certain distance, to hold and fixing scolder 108 ' (as shown in figure 12) or the like, and scolder is except fixing by insulating body or conducting terminal and insulating body, also can fix by conducting terminal, as through hole 112 peritremes of conducting terminal weld part 110 inwardly being given prominence to fixing scolder (as shown in figure 13), or conducting terminal weld part 120 is designed to the tubulose (as shown in figure 14) of tool fluting 122, or conducting terminal weld part 130 formation two arms 132 wait clamping scolder (as shown in figure 15), and scolder also can be made as other shape, as cylindric, prism-shaped, discoidly wait other non-spherical, but no matter which kind of mode of employing, scolder in the above-mentioned electronic component can both meet the needs of and make than low height or less width, guarantees that electronic component has than low height or less conducting terminal spacing.

Compared to prior art, the scolder of electronic component provided by the utility model adopts non-sphere, under certain tin amount condition, making, thereby can make electronic component have and can guarantee good welding effect than low height or less conducting terminal spacing than low height or less width.
