Description

[Detailed description of the invention] This invention prevents the board from being deformed due to the mounting of conductive terminals when a terminal board is constructed by mounting a large number of conductive terminals into mounting holes provided in the board. This invention relates to conductive terminals for terminal boards intended for use in terminal boards.

Conventionally, in order to manufacture a terminal board that can be connected to a printed circuit board, a board made of an insulating material is provided with the necessary number of mounting holes for mounting and fixing conductive terminals in a straight line, as shown in Figure 1. As shown, on the lower side of both sides of the eye-shaped screw threading part 20,
a conductive piece 21 in contact with the connecting end of the printed circuit board;
21 are arranged in series so that the connecting end can be sandwiched between the two conductive pieces 17 and 17, and both side edges of the screw threaded part 20 are formed into hooking edges. terminal 2
2 is attached so that the hooking edge and the mounting hole walls (left and right walls) of the board are hooked, so that the deformation of the board due to the mounting of the conductive terminal 22 is overlapped in the longitudinal direction of the board. However, as the number of conductive terminals increases, the board becomes curved.

However, in this invention, the latching edge formed in the screw attachment part and which engages with the mounting hole of the board faces the wall surfaces (front and rear walls) perpendicular to the longitudinal direction of the board, so that the board can be easily attached to the board by attaching conductive terminals. The deformations of the substrate were no longer superimposed in the longitudinal direction, and the substrate was successfully prevented from curving.

That is, to explain this invention with reference to an embodiment, a conductive plate is bent into a cross-sectional shape, a screw 7L1 is bored in the center of the top piece 2a to form a screw threaded part 2, and the side end of the side piece 2b is The edge is made into a serrated hooking edge 3, and a trough-like bent part 4 with a "shaped cross section and a hanging piece bent into a trough-like shape is formed on the inside of the lower end of one side piece 2b, and the trough-like bent part 4 A conductive terminal 7 for a terminal board is constructed by connecting an elastic clamping part 6 consisting of arc-shaped conductive pieces 5, 5 to the lower side of the part 4 in a direction perpendicular to the side piece 2b of the screw threaded part 2.

In the figure, 8 is a split groove provided in the arc-shaped conductive pieces 5, 5, and 9 is a temporary fixing projection formed on the outer surface of the side piece 2b of the screw threaded part 2 by pressure punching into an upwardly tapered surface shape. It is.

Next, FIGS. 5 and 6 show leg plates 11, 11 (
5) is bent in a gutter-like manner toward one side of the other side, and the lower end portions of the leg plates 11, 11 are formed in an arc shape to form an elastic clamping portion perpendicular to the side piece of the screw threaded portion 10. 12 is formed to form a conductive terminal 13 for a terminal board.

The terminal board is completed by inserting and latching the conductive terminals 7 and 13 for the terminal board of the above embodiment into the conductive terminal mounting holes 15 provided in the negative row of the substrate 14 made of an insulating material.

- As an example, using the conductive terminals 13 for a terminal board shown in FIGS. It is inserted from the part 12 side, and the locking edge 3 formed on the screw threading part 10 is attached to the front and rear walls of the mounting hole 15 (the direction perpendicular to the longitudinal direction of the board 14 is defined as the front and rear direction).

), the elastic clamping part 12 is positioned in the connecting part 17 formed by sandwiching the partition wall 16 at the lower part of the conductive terminal mounting hole 14, and is completed.

The latching edge 3 is serrated, so there is no risk of the latching coming off and coming off.

However, due to the relationship between the conductive terminals 13 and the substrate 14, the deformation of the substrate 14 due to the engagement of both is only in the front and rear directions. The deformations of the board 14 for each terminal are not superimposed, and therefore the board 14 can be prevented from curving.

As described above, the elastic clamping part 12 is in the direction perpendicular to the side piece of the screw threading part 10, so that when it is attached to the board 14, it is parallel to the front and rear surfaces of the board 14, and the printed circuit board 18 is As shown in FIGS. 8 and 9, connections are made between each elastic clamping part 12 and the side edge of the printed circuit board 18 by inserting the negative side edge into the connection part 17. The two ends are connected in one motion.

In the figure, reference numeral 19 indicates a screw screwed into the screw threaded portion 2.

That is, according to this invention, the retaining edges formed on the screw threading portion are engaged with the front and rear walls of the conductive terminal mounting hole of the board, and in this state, the printed circuit board inserted parallel to the longitudinal direction of the board is inserted. Since the connecting ends can be connected in a pinched state,
This has the effect of efficiently manufacturing a terminal board that can be connected to a printed circuit without bending or deforming it.
