Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a printed circuit board mounting terminal for electrically connecting circuits on a printed circuit board.

[Prior art]

Conventionally, this type of printed circuit board mounting terminal includes a U-shaped conductive member 1 having through-hole insertion legs 1a fixed to a printed circuit board 3 having through holes 2, as shown in FIG. It has been adopted.

However, in conventional printed circuit board mounting terminals, the four through-hole insertion legs 1a are inserted into the same number of through holes 2, so circuits on the printed circuit board 3 cannot be selectively connected. Nakatsuta.

[Summary of the idea]

The present invention was developed in view of these circumstances, and consists of four through-holes that are formed on both sides of a U-shaped conductive member at the vertices of a rectangle on the printed circuit board depending on the mounting orientation. 3 of us
With the extremely simple configuration of extending three through-hole insertion legs that can be selectively inserted into one through-hole, jumper connection of the circuit can be made by simply selecting the direction in which the conductive member is installed on the printed circuit board. This provides printed circuit board mounting terminals that can be selected without making insertion mistakes. Hereinafter, the configuration and the like will be explained in detail by referring to embodiments shown in the drawings.

〔Example〕

FIG. 2 is a perspective view showing how the printed circuit board mounting terminal according to the present invention is attached to the printed circuit board, and FIG. 3 is a plan view showing the through holes of the printed circuit board. In the figure, reference numeral 11 indicates a printed circuit board, and four through holes 12 are provided at the vertices of a rectangle with two sides of, for example, 7 mm and 6.6 mm. Reference numeral 13 denotes a U-shaped printed circuit board mounting terminal made of a conductive material, with opposite side pieces 1
3a, three through-hole insertion legs 14 each extending in the same direction and capable of being selectively inserted into three of the four through-holes 12;
has been extended. That is, the through-hole insertion foot 14 is such that two through-hole insertion feet 14a and 14b are positioned on one side of the both side pieces 13a, and one through-hole insertion foot 14c is positioned on the other side. It is provided. Then, these through-hole insertion legs 14 are inserted into the through-holes 12, and the printed circuit board mounting terminals 13 are fixed to the printed circuit board 11. The base 13b of the printed circuit board mounting terminal 13 is provided with a screw hole 16 for screwing a cable terminal (not shown) with a screw 15, and a selection circuit 17 is provided on the side of the screw hole 16. A mark 18 for distinguishing is displayed. Further, this base portion 13b faces the printed circuit board 11 when the printed circuit board mounting terminal 13 is attached to the printed circuit board 11.

In the printed circuit board mounting terminal configured in this way, the through-hole insertion legs 14a, 14b, and 14c are inserted into the through-holes 12a, 12b, and 12c as shown in FIG. , 12c and 12d, two different types of circuit connections can be made. That is, jumper connection of circuits can be selectively performed simply by rotating the printed circuit board mounting terminal 13 by 180 degrees and changing the mounting direction to the printed circuit board 11. In this case, the selected circuit can be identified by the position of the mark 18 at a glance from above. Also,
Because the pitch of the through hole 12 is different vertically and horizontally,
The mistake of inserting the through-hole insertion foot 14 in a position other than the 2nd position does not occur.

Although this embodiment shows the printed circuit board mounting terminal 13 in which the through-hole insertion foot 14 extends in a direction perpendicular to the base 13b, the present invention is not limited to this. Of course, the printed circuit board mounting terminal 19 may have a through-hole insertion foot 19b extending in a direction parallel to the base 19a as shown in the figure.

[Effect of idea]

As explained above, according to the present invention, three through holes are provided on both sides of the U-shaped conductive member, which can be selectively inserted into three of the four through holes provided on the printed circuit board side. Since the insertion legs extend, circuit connections on the printed circuit board can be reliably made in the desired state simply by selectively changing the direction in which the conductive member is assembled onto the printed circuit board.

In addition, according to the present invention, since the through-hole is provided at the apex of the rectangle on the printed circuit board, the through-hole pitch is different vertically and horizontally, which makes it possible to insert the through-hole in positions other than the two positions. When the legs are inserted, there will be no insertion/connection errors on the circuit wiring.
