【考案の詳細な説明】 (イ) 産業上の利用分野 本考案は印刷配線板に関するものである。[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to printed wiring boards.
(ロ) 従来技術
従来から印刷配線板に於いては、印刷配線板に
リードピンを取付け、コネクタを嵌合させるだけ
で他の印刷配線板との接続を容易にする工夫がな
されている。例えば第１図に示す様に、鉄板等の

成し、導電板１、絶縁層２、回路パターン３を貫
通す挿通孔４を形成するとともに、この挿通孔４
より小径のリードピン５を導電板１に接触させな
いように挿通孔４に挿入するとともに回路パター
ン３に半田６付けした印刷配線板７が知られてい
る。(B) Prior Art Conventionally, printed wiring boards have been devised to facilitate connection with other printed wiring boards by simply attaching lead pins to the printed wiring board and fitting connectors. For example, as shown in FIG. 1, a circuit pattern 3 is formed on a conductive plate 1 such as a steel plate through an insulating layer 2, and an insertion hole 4 passing through the conductive plate 1, the insulating layer 2, and the circuit pattern 3 is formed. , this insertion hole 4
A printed wiring board 7 is known in which a smaller diameter lead pin 5 is inserted into the insertion hole 4 so as not to come into contact with the conductive plate 1 and is soldered 6 to the circuit pattern 3.
しかしこの様な印刷配線板は挿通孔４を打抜き
等で形成する際、回路パターン３の端部にバリが
生じて導電板１に接触して不良品が発生し易い。 However, in such a printed wiring board, when the insertion holes 4 are formed by punching or the like, burrs are generated at the ends of the circuit pattern 3 and come into contact with the conductive plate 1, resulting in the production of defective products.
このため回路パターンにバリを生じさせない構
造として第２図に示す様に、回路パターンを予め
大径に形成したものも提案されている。 For this reason, as a structure that does not cause burrs on the circuit pattern, a structure in which the circuit pattern is previously formed to have a large diameter, as shown in FIG. 2, has been proposed.
ところが第２図の様な印刷配線板に於いても、
リードピン５を導電板１に接触しない様に支持し
ながら回路パターン３に半田付けしなければなら
ないので、製造が面倒である上、リードピン５と
回路パターン３との間隔が長くなるので、半田付
け不良が生じ易い欠点がある。 However, even in printed wiring boards as shown in Figure 2,
Since the lead pin 5 must be soldered to the circuit pattern 3 while being supported so as not to come into contact with the conductive plate 1, manufacturing is troublesome, and the distance between the lead pin 5 and the circuit pattern 3 becomes long, resulting in poor soldering. It has the disadvantage that it tends to occur.
更に第１図、第２図の様な構造にせずに従来公
知のコネクタを導電板に取付けてもよいが、取付
け用のネジ等が必要となつて、やはり部品点数が
増加しコスト高を招くという欠点がある。 Furthermore, conventionally known connectors may be attached to the conductive plate without having the structure shown in Figures 1 and 2, but screws, etc. for attachment are required, which increases the number of parts and increases costs. There is a drawback.
(ハ) 考案の目的
本考案は斯る点に鑑み、上記の欠点を解消し、
組立が簡単で外部接続を容易に行なうことが出来
る安価な印刷配線板を得ることを目的としてい

The purpose is to obtain an inexpensive printed wiring board that is easy to assemble and can be easily connected to the outside.

It is a connector. The connector 15 has a locking portion 17,
17' and a support portion 18 that protrudes downward, and the lead pin 16 protrudes from the right side surface 19 of the locking portion 17 and the lower end surface 20 of the support portion 18. The connector 15 is installed with the support part 18 press-fitted into the insertion hole 14, the support part 18 being supported between the clamping pieces 13, 13, and the locking parts 17, 17' being locked on the top surface of the printed wiring board 12. The lead pin 16 protruding from the right side surface 19 of the locking portion 17 comes into contact with the circuit pattern 11 and is soldered 27 thereto.
