【考案の詳細な説明】
本考案はラジオ、ラジカセ等フロントケースとバックケ
ースの間に挟持されるプリント基板の電気的接続装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical connection device for a printed circuit board held between a front case and a back case of a radio, boombox, etc.
従来この種の接続は、リード線を基板のパターンに半田
付けするか又は基板にファストン、ピンを半田付けしリ
ード線にコネクタを取付けて接続していた為、二つのケ
ースの間がリード線でつながっていて、組立時、サービ
ス時に於て断線、接続もれ等が生じていた。Conventionally, this type of connection was made by soldering the lead wire to the pattern on the board, or by soldering a faston pin to the board and attaching a connector to the lead wire, so the lead wire was connected between the two cases. However, disconnections and connection leaks occurred during assembly and service.
又ケースを閉じた状態では、ノード線が自由となりビリ
ツキの原因にもなる事があった。In addition, when the case is closed, the node wires become free, which can cause twitching.
本考案の目的は、２つのケースをリード線でつなぐこと
なく、組立時、サービス時の断線、接続もれ、又ビリツ
キをなくした接続装置を提供するにある。An object of the present invention is to provide a connecting device that eliminates disconnection, leakage, and twitching during assembly and service without connecting two cases with lead wires.
以下本考案の実施例を図面を用いて説明する。Embodiments of the present invention will be described below with reference to the drawings.
第２図に示す様にプリント基板３を２つのケース２．５

る事なく電気的接続を得る様にしてなる。As shown in Figure 2, the printed circuit board 3 is placed in two cases 2.5.
In this structure, a conical coil spring 1 with a large diameter and an open winding at one upper end is press-fitted into the boss 2a of one case 2, and a lead is attached to the other. Connect the pattern of the printed circuit board 3 to which the wire 6 has been soldered by tightening the bosses 2a and 5a of the two cases 2 and 5 with the screw 4, crimping the open winding side of the coil spring 1, and connecting the two cases 2 and 5. Electrical connection is obtained without connecting with the lead wire 6.
ここでプリント基板３のパターン面と接触にて電気的接
続をする為にコイルスプリング１の形状を第１図に示す

としたことにより、又ケース２，５、プリント基板３の
温度変化による寸法変化を考慮し巻数を多くしてたわみ
を取り、又短かいボス２ａに取付ける為の密着時の寸法
を小さくすることができる。Here, in order to make an electrical connection through contact with the patterned surface of the printed circuit board 3, the shape of the coil spring 1 is made so that one side is open-wound as shown in FIG. can also be made to break through the film,
Also, by making it conical, the pattern surface of the printed circuit board 3 attached to the case 5 can be easily fitted to the coil spring 1 from any direction, and the assemblability can be improved. In consideration of dimensional changes due to temperature changes in the printed circuit board 3, the number of turns can be increased to take up the deflection, and the dimensions can be reduced when tightly attached to the short boss 2a.

Claims (1)
ものに於て、一方を開放巻とし他方にリード線を接続し
た円錐形状のコイルスプリングを、一方のケースのボス
に圧入して両ケースをネジ締めしてスプリングの開放巻
側を基板パターンに圧着して、電気的接続を得る事を特
徴とする接続装置。In cases where printed circuit boards are fastened together using bosses provided on two cases, a conical coil spring with open winding on one side and a lead wire connected to the other is press-fitted into the boss on one case, and both cases are fastened together. A connection device characterized in that an electrical connection is obtained by tightening a screw and crimping the open side of a spring to a circuit board pattern.
