Abstract
The utility model relates to a passive component group which comprises a passive component body and a base board. A cylindrical feed-through portion and a flat fixing portion are formed at the pin of the passive elements. The base board is provided with a cave which can be used for the embedding of the body. A plurality of groups of combination holes, each group of the combination holes is relative to a pin are arranged in the cave. The combination holes comprise a flat pin portion and a steering pin portion which are formed by overlapping. The flat pin portion is relative to the fixing portion and is matched with the fixing portion in size. The steering portion is corresponding to the steering portion of the pin and the interior diameter of the steering portion of the pin is somewhat larger than the external diameter of the steering portion. Thereby while installing, the passive elements can be infixed into the steering portion of the combination holes through the steering portion of the pin, further the close fixing is realized by embedding from the fixing portion of the pin into the flat pin portion, thereby reducing the gap and reaching stable combination.
Description
Technical field
The utility model is about a kind of passive device, refers to a kind of passive device group that reduces the gap thereby can reach firm combination especially.
Background technology
Passive device (for example: capacitor or resistance etc.) is generally to be installed on the circuit board, but its mat certain way carries out the control of circuit, makes the electronic installation that is equiped with this circuit board reach the start of expection.
In today that the electronic installation precision requirement promotes day by day, how passive device firmly is installed on the circuit board and avoids influencing its start, has formed an important problem.Passive device generally is to include a passive device body and a seat board for passive device body integrated positioning, all be formed with circular combination bore on the present employed seat board, when both sides bent, it fixed impetus and only depends on its all side 2 points after the pin of passive device body penetrates combination bore; And this seat board is to be plastic products, thus become when the two edge break pin angle and point against, cause the cracked of combination bore peritreme easily, and rocking after causing making up.Because it rocks, when this passive device and circuit board surface stick together, can't be connected in the predetermined conductiving point of circuit board accurately.
And for example its seat board changes the rectangle combination bore into, and then the width of this rectangle combination bore must can penetrate for it greater than the diameter of the guide hole post of passive device body; Yet it penetrates the back holding division and combination bore will form very big gap, so after this passive device body combination, will cause serious rocking.
In addition, the circular section pin that passive device had is when outwards bending is placed in the pin groove of seat board bottom, be must further exert pressure processing could be smooth, trim in the seat board bottom, cause shakiness to avoid outstanding replacing to circuit board surface; Not only increased the Operating Complexity of passive device and seat board assembling process thus, and the shape area behind the pin compressive deformation is to be difficult to control, the time regular meeting and groove the both sides inwall between still have certain interval, have influence on when connecting firmly.
Summary of the invention
Because the passive device of prior art when combining with seat board, still can't reach firmly really, this creator further provides passive device group of the present utility model after further investigation.
Passive device group of the present utility model not only can firmly be incorporated on the circuit board really, can not rock because of the gap causes producing, and its assembling is gone up very convenient, quick.
For reaching aforementioned purpose, the technological means that passive device group of the present utility model is used provides a passive device body and a seat board, wherein:
This passive device body includes the plural pin that is connected in the bottom, and the contiguous free end of each pin partly forms columned guide hole portion, and the part of contiguous passive device body forms flat-shaped holding division;
This seat board is formed with the appearance cave that can supply the passive device body to insert, penetrate in this appearance cave that to be formed with plural combination bore corresponding with the pin of passive device respectively, wherein each combination bore is to include a flat hole portion and the guide hole portion that mutual overlapping forms, this flat hole portion conforms to the holding division size of passive device pin, and that this guide hole portion can be circular cone is poroid, and its internal diameter is slightly larger than the external diameter of guide hole portion; So, can be earlier when then assembling penetrate in the guide hole portion of combination bore with the guide hole portion of passive device pin, obtain guiding by this and make things convenient for pin to take advantage of a situation to slip into, and then embed with holding division and to reach engaging closely in the portion of flat hole, it can reduce the gap thereby can locate really, avoids the passive device body to produce and rocks.
In addition, aforementioned seat board bottom can be formed with plural number folding pin groove, and each rolls over pin groove size size is corresponding with the holding division of a pin respectively, can be closely chimeric with holding division for the pin bending, and make the seat board bottom directly form even curface; Its must be not other processing, therefore more quick in the assembling, convenient, and by holding division with roll over the closely chimeric of pin groove, can more and then provide firm adhesion, more firm when making passive device body mat seat board be installed on the circuit board.
