Description
【発明の詳細な説明】 この発明は電子部品リード切断方法に関する。[Detailed description of the invention] The present invention relates to a method for cutting electronic component leads.

うにしている。 When loading electronic components such as capacitors, resistors, or various semiconductor devices onto a printed circuit board, insert the leads of the electronic components into the mounting holes provided on the printed circuit board, and cut the legs that protrude from the back side to an appropriate length. After that, they are fixed with solder or the like.

る。 Figures 1 to 3 show a conventional lead cutting method, in which 1 is an electronic component, 2 is a plurality of leads, 3 is a board such as a printed circuit board, and 4 is a loading hole provided in the board 3 for inserting the leads. , 5 is a cutter with upper blade 6 and lower blade 7
Each blade is provided with penetrating blade portions 8 and 9. The leads 2 of the electronic component 1 are inserted into each of the loading holes 4. The extracted lead 2 is then inserted into each of the blade portions 8 and 9 of each of the blades 6 and 7. FIG. 2 shows the state at this time.
Then, with the board 3 and the upper blade 6 fixed, the lower blade 7
move in the direction of the arrow. Then, the legs of the lead 2 are cut by the sliding contact between the upper blade 6 and the lower blade 7. At this time, as shown in FIG. 3, the lead 2 is bent in a dogleg shape within the blade portion 8 along the moving direction of the lower blade 7.
ところでこのように切断したとき、リード２が
屈曲しているので、リード２はこれが真直な場合
よりも抜けにくくなり、したがつて簡単に電子部
品１が基板３から離脱しないようになつて都合が
よいが、しかし図示の状態から理解されるように
各リード２はいずれも同じ方向に屈曲しているの
で、その屈曲方向に沿つて上方に引上げたとする
と、簡単に装填孔４から抜け出てしまうことがあ
る。このような抜け出しは、リードを半田で固定
するまではできる限り阻止することが望ましいこ
とはいうまでもない。 By the way, when the leads 2 are cut in this way, since they are bent, the leads 2 are more difficult to come off than if they were straight, and therefore the electronic component 1 is not easily separated from the board 3, which is convenient. However, as can be understood from the illustrated state, each lead 2 is bent in the same direction, so if you pull it upward along the bending direction, it will easily come out of the loading hole 4. There is. Needless to say, it is desirable to prevent such slippage as much as possible until the leads are fixed with solder.
この発明はリードが基板から簡単には抜け出な
いような形状に切断することを目的とする。 The purpose of this invention is to cut the leads into a shape that prevents them from easily coming out of the board.
この発明は各リードのうちの少くとも２本のリ

ことを特徴とする。 The present invention is characterized in that at least two of each lead are cut while being bent in opposite directions.

定されてある。 Embodiments of the present invention will be described with reference to FIG. 4 and subsequent figures. Note that parts given the same reference numerals as in FIGS. 1 to 3 indicate the same or corresponding parts. The loading hole 4 of the upper blade of the cutter 5 used in this invention is as follows:
At least two are provided along the shearing direction indicated by the arrow. In addition, the lower blade 7 has its respective blade portions 9A and 9B.
are rectangular in shape, at least two are provided in the shearing direction, and are inclined with respect to the shearing direction. In this case, each blade part 9A,
9B, the linear oblique side (cutting edge) 9a, 9
b are made not to be parallel to each other, and in the example shown in the figure, they are tilted so as to be symmetrical with respect to a line perpendicular to a line L along the shearing direction. The lines L are set along a line connecting both leads 2, for example, parallel to each other.

屈曲されながら切断されていく。 The lead 2 is cut by inserting the lead 2 into the loading hole 4 of the board 3 in the same way as in the conventional method. Then, each lead 2 extracted from this is further inserted into the blade part 8 of the upper blade 6 and the lower blade 7.
Insert into the blade portions 9A and 9B. Then, the lower blade 7 is moved in the direction of the arrow, that is, in the shearing direction. Figure 5 sequentially shows the cutting process at this time.
indicates the initial state, and when the lower blade 7 moves in the direction of the arrow from here, the lead 2 contacts the rear oblique side 9a of the blade portion 9A and the rear oblique side 9b of the blade portion 9B, as shown in B. . When the lower blade 7 moves further, the lead 2
tend to come into sliding contact along the oblique sides 9a and 9b.
When the lower blade 7 moves further, the legs of the lead 2 are cut by the double blade parts 8, 9A, and 9B. At this time, regarding the lead 2 inserted into the blade part 9A, the moving direction of the lower blade 7 is P1 , and the inclination direction of the oblique side part 9a is P2 .
If so, the lead 2 is bent and cut in the direction toward the composite direction P 3 of both directions P 1 and P 2 . Similarly, regarding the lead 2 inserted through the blade portion 9B, if the inclination direction of the hypotenuse portion 9b is P 2 ′, the lead 2 is bent in the direction toward the composite direction P 3 ′ of both directions P 1 and P 2 ′. It is cut off while being cut off.
そして両刃部９の斜辺部９ａ，９ｂは互いに反

参照）。そのため電子部品１を基板３から引抜こ
うとする力が働いても、少くとも一方のリードが
装填孔４に引掛るようになり、したがつて簡単に
は引出すことができないようになる。 Since the oblique sides 9a and 9b of the double-edged portion 9 are inclined in opposite directions, both leads 2 are bent in a dogleg shape in opposite directions (see FIG. 6). Therefore, even if a force is applied to pull out the electronic component 1 from the board 3, at least one lead will be caught in the loading hole 4, and therefore it will not be possible to pull it out easily.

を、異なる角度で傾斜させておけばよい。 For electronic components having three or more leads, two of them may be cut according to the present invention, and the remaining leads may be cut with a blade portion having the same shape as the conventional one.
Alternatively, it goes without saying that the remaining leads may be cut in different bending directions in the same way as the two leads described above. For this purpose, the blade portion for cutting the remaining leads may be inclined at different angles.

防止できるといつた効果を奏する。 As detailed above, according to the present invention, at least two leads of an electronic component are inserted into the board and then cut from the parts that are pulled out from the board by bending them in opposite directions. After cutting, the lead is caught in the loading hole of the board and becomes difficult to come out, thereby achieving the effect that separation from the board can be reliably prevented.
