２が形成されているものである。FIGS. 1 and 2 show a conventional female electrical connector of this type. This female electrical connector 6 has both sides of the bottom wall 6h bent upward to form both side walls 6C1 and 6C2. Further, the upper portions of the side walls 6C1 and 6C2 are respectively bent inward to form elastic contact portions 6a1 and 6a2, and pairs of claws 6e1 and 6e2 are protruded from the upper edges of the side walls 6C1 and 6C2, respectively. At the same time, there are protrusions 6g1 and 6g at the bottom of both side walls for contacting the printed circuit.

2 is connected in contact with the exposed circuit surfaces 7a1 and 7a2 of the flexible printed circuit board 7 bent into the mounting hole 8a. When an electrical connector with such a structure is used, for example, the flexible printed circuit board 7 When removing the electrical connector 6 from the board for the purpose of replacing the circuit board, the female electrical connector 6 must be removed from the board unless the male terminal 5 inserted into the female electrical connector 6 is pulled out. It was impossible to remove it from the mounting hole 8a of No.8.

り成る電気接続子であるから本考案によれば次の如き効
果がある。As described above, the present invention provides an opening having a pair of notches 3b1 and 3b2 provided in the electrically insulating substrate 3 and barrier walls 3C1 and 3C2 provided on one side of the insulating substrate corresponding to the notches. 3a, an electric device is inserted into one side of the insulating substrate, and a printed circuit board 2 is installed on the other side of the insulating substrate.
An electrical connector that connects a rectangular substrate portion 1a formed of an electrical conductor, a pair of sidewall portions 1b1 and 1b2 that stand up at right angles from two opposing sides of the substrate portion 1a, and the sidewall. elastic contact portions 1C1 and 1C2 provided at the ends of the portion and capable of sandwiching the male terminal 4 connected to the electric device; and cut and raised from each of the side wall portions parallel to the substrate portion 1a,
They are spaced apart from each other at regular intervals, and one of the notches 3 b, 3
1 that can be inserted through b2 and engaged with the periphery of the opening 3a;
Pair of cut and raised tongue pieces 1 fl, 1 f2, 1gt, Igz
and elastic contact pieces 1d1 and 1d2 that extend diagonally laterally from the other two opposing sides of the substrate portion 1a and can contact the circuit foil of the printed circuit board 2 held on the insulating substrate 3. Since it is a connector, the present invention has the following effects.

ａ 雌型電気接続子が絶縁基板とプリント基板に設けた
透孔にワンタッチで接続できるので従来のナラｌ−締め
による方法に比べ作業性が良く組立工数が少なくて済む
。a) Since the female electrical connector can be connected to the through hole provided in the insulating substrate and the printed circuit board with one touch, the workability is improved and the number of assembly steps is reduced compared to the conventional l-tightening method.

ｂ 電気装置に設けた雄端子及びプリント回路との接続
は全てスプリングコンタクト方式である為、安定した電
気的接触が得られる。b. All connections with the male terminals provided on the electrical device and the printed circuit are spring contact type, so stable electrical contact can be obtained.

Ｃ雌型電気接続子の取付が適当なる回転角を与えて、組
み付けるので振動等が加わった場合、従来方式がナツト
のゆるみ、即ち接触不良に継かったのに比べ、電気接続
子の回転角度の範囲で若干の振動等による位置の移動が
仮にあっても電気接続部へ与える影響はほとんどない。Since the C female type electrical connector is installed with an appropriate rotation angle and assembled, if vibration etc. are applied, the rotation angle of the electrical connector will be reduced compared to the conventional method which would result in loosening of the nut or poor contact. Even if there is a slight shift in position due to vibration, etc. within this range, it will have almost no effect on the electrical connections.

しかも、雄端子及びプリント回路面と各スプリングとの
接触による摩擦の為簡単に位置の移動も起らない。Moreover, the position does not easily shift due to friction caused by contact between the male terminal and the printed circuit surface and each spring.

ｄ 従来方式がプリント回路面より後方へかなりの高さ
露出して周辺の電気配線のターミナル等とショー ト事
故を起し易い構造であるのに対して、本考案ではプリン

ピングしても良いので電気的に安全な電気接続子を提供
出来る。d The conventional method has a structure in which the printed circuit is exposed at a considerable height backward from the printed circuit surface, easily causing short-circuit accidents with surrounding electrical wiring terminals, etc., whereas in the present invention, the printed circuit is exposed backward from the printed circuit surface. It is electrically safe because the height of the electrical connector is extremely low and, depending on the case, the electrical contact part may be masked in advance with a suitable jig and the electrical part may be coated with insulating paint or dipped with insulating material. We can provide electrical connectors.

ｅ 電気接続子の組立工層の選択が自由である。e) Free selection of the assembler level for electrical connectors.
