度を大きくして小さな基板を使用しても複雑な回
路構成を有するキツトを提供できるのである。 Taking these differences into consideration, this proposal provides coil spring terminals for the external circuit connection terminals, provides upward insertion type sockets for the internal circuit component connection terminals, and allows the lead wires to be folded when changing component connections. It is designed to be able to be carried out quickly and accurately without bending over, and it also reduces the space occupied by these connection terminals on conventional boards, increases the packaging density of circuit components, and eliminates the need for complex circuits even when using a small board. A kit having the circuit configuration can be provided.
本案品の実施例を第1図について説明する。 An embodiment of this product will be described with reference to FIG.

2は、電池その他の外部回路を接続するための
コイル状端子であつて撚線の挟み込み接続が容易
に行なえる。 Reference numeral 2 denotes a coiled terminal for connecting a battery or other external circuit, and connection of twisted wires can be easily made by sandwiching the wire.
3は回路部品差替用ソケツト、4は抵抗、コン
デンサ、トランジスタ等の回路部品、5はその単
線リード線である。 3 is a socket for replacing circuit components, 4 is a circuit component such as a resistor, capacitor, transistor, etc., and 5 is a single lead wire thereof.
差替用ソケツトの構造は第2図のようであつ
て、7は、中心にリード線を挿入する孔6を有す

設けられている。 The structure of the replacement socket is as shown in Fig. 2, where 7 is an inner cylinder made of contact-resistant elastic metal such as Be-Cu or phosphor bronze, which has a hole 6 in the center for inserting the lead wire, and a A clamping portion 9 is provided with a slit 8 or the like.
10は、ホルダーであつて内筒7をその中心孔
11内に嵌着している円筒部12とその底部に突
設した取付ピン13を備えている。 Reference numeral 10 denotes a holder, which includes a cylindrical portion 12 into which the inner tube 7 is fitted into its center hole 11, and a mounting pin 13 protruding from the bottom of the cylindrical portion 12.
取付ピン13は基板1を貫通し裏面の配線部1
4に達してハンダ付15されることによつてホル
ダー10を基板上に固定するものである。 The mounting pin 13 penetrates the board 1 and connects to the wiring section 1 on the back side.
4 and is soldered 15 to fix the holder 10 on the board.
16は、ホルダーの中心孔の外端面に設けたリ
ード線挿入案内用テーパである。 Reference numeral 16 denotes a lead wire insertion guide taper provided on the outer end surface of the center hole of the holder.
17は絶縁性合成樹脂製の外筒であつてホルダ
ーの外周面を被覆している。 Reference numeral 17 denotes an outer cylinder made of insulating synthetic resin, which covers the outer peripheral surface of the holder.

判り易くなる。 Incidentally, the socket 3 may be used as a single unit, but it is also possible to combine a plurality of sockets into one set by joining the synthetic resin outer cylinder 17, thereby making it easier to design and assemble the board. Along with this, it becomes easier to insert and remove the lead wire, and the assembly of the kit becomes easier to understand.
以上の如く本案基板においては撚線用接続端子
