問題があつた。 The above terminal a is fixed to the housing g by using the board c
This is done by engaging the lance e formed on the back surface with the locking groove f inside the housing as shown in FIG. In this lance method, an overstroke D is always required in order to insert the lance e to the locking groove f, and therefore, wobbling occurs by the amount of the overstroke D after insertion. the result,
Wire wear and disconnection occur at the connection between the wire and the terminal. In addition, in the case of a pressure method in which lance e is omitted and the lower end of board c is press-fitted into the housing, terminal a
The width of slot b changes in order to press the upper end of the slot b. Furthermore, regardless of whether the lance method or the press-fit method is used, the side plate c' bent in an inverted U shape from the substrate c has an elastic piece h in contact with the substrate c;
Its tip is in an open state. Therefore,
When press-fitting the wire into slot b, press one side plate.
There were problems such as the position c' shifted downward, the wire press-fitting position of the opposing slot b was different, and the slot b expanded beyond the allowable stress, resulting in insufficient contact pressure.

接型端子Ａが連鎖状に形成される。Means for Solving the Problems To explain the present invention based on the drawings, in Figs. 1 to 3, 1 is a conductive metal plate having a predetermined width, and the central part along the longitudinal direction is centered at 1. A pair of side plates 2, 2 facing each other are formed by bending it into an inverted U-shape. The side plate 2 is provided with a wire press-fitting slot 6 having an enlarged opening 5 at the bending top 3 in an inverted U-shape from the bending top 3 toward its free edge 4.
will be established. A plurality of slots 6 are provided at predetermined intervals, and separating grooves 7 are provided between adjacent slots 6 to define each slot 6, and a connecting base piece 8 is provided below the groove 7. By leaving them alone, a plurality of press-contact type terminals A are formed in a chain.

ができる。Operation To press-fit and fix the chain-shaped pressure contact type terminals A into the housing, as shown in FIGS. When inserted and the connecting base piece 8 is pushed down, the tapered press-fitting part 9 fits into the press-fitting groove 1 of the housing 12.
3 can be easily reached and achieved easily. When press-fitting the chain-shaped terminals A, the press-fitting part 9
Since it is tapered, the synthetic resin housing 12 will not be contaminated by chips, and the press-fitting jig 10 will not come into contact with the slot 6 or its bent top 3, so the slot 6 will not be deformed. . In addition, since the lower free edges (including the press-fitting part 9) of the opposing side plates 2, 2 are fixed, there is no problem such as the press-fitting position being different when press-fitting the wire into the slot 6, and stable electricity is ensured. You can get the desired connection status. Furthermore, even if the chained terminals A are separated as described above and the number of poles is changed, connecting pieces 8 of sufficient length will protrude from both sides of the side plate 2 and remain at the cut site. It can be press-fitted easily.
