Description

[Detailed Description of the Invention] The present invention relates to a terminal of a printed circuit board, and particularly to its mounting structure.

In conventional printed circuit board terminals, as shown in Figures 1 to 3, a lead wire L is connected to terminal a.
cylindrical socket c for connection hole b and board d, etc.
When attaching the terminal a to the board d, insert the cylindrical part c into the mounting hole e provided in the board d, and use a fitting jig to open the part c. After fitting onto the board d, the fitting part c is soldered s.

However, although printed circuit boards are generally assembled in large numbers at once using self-insertion machines, conventional terminals require a fitting process that is independent of the insertion and soldering process of other parts. This requires a process, which requires securing equipment and increasing the number of processing steps. In addition, since the cylindrical eye part c of the terminal is formed by drawing, there is a limit to the length that can be obtained, and in particular, it cannot be used for thick boards. Since it is made of a relatively soft material to perform this, it tends to be deformed to some extent when it is assembled to a board.

Furthermore, in conventional terminals, the connection hole b for the lead wire L etc. is provided only at one end where it does not interfere with the board d, so as shown in FIG.
Even when connecting a plurality of lead wires L to a terminal, there is a drawback that they must be concentrated in one place.

An object of the present invention is to provide a printed circuit board terminal that eliminates the drawbacks of the prior art described above and has excellent workability.

In order to achieve this object, the present invention consists of an upright piece extending in the vertical direction and a mounting piece extending in the horizontal direction, and a part of the upright piece is cut and suspended in a direction opposite to the upright direction of the upright piece. The present invention is characterized in that a locking portion to the substrate is formed and a portion of the mounting piece is bent and suspended substantially parallel to the locking portion to form a fixing portion to the substrate.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 4 to 8.

The terminal 1 consists of an upright piece 2 that extends in the vertical direction and a mounting piece 3 that extends in the horizontal direction and is placed on a board 8. The upright piece 2 and the mounting piece 3 form a substantially L-shaped main body. . A portion of the upright piece 2 has a notch 4 formed by cutting it upward in a tapered shape, and the cutout piece is bent in the opposite direction to the upright direction of the upright piece 2 to form a hanging part. A locking piece 5 having a tapered tip is provided, and the mounting piece 3 is provided with a fixing piece 6 which is partially cut out and bent, and is formed to hang down approximately parallel to the locking piece 5. A connection hole 7 for a lead wire L or the like is bored in one end of the mounting piece 3 adjacent to the fixed piece 6. The board 8 to which the terminal 1 is attached has a circular hole 9 into which the locking piece 5 of the terminal 1 engages and a rectangular hole 10 into which the fixing piece 6 of the terminal 1 is inserted. When fixing the terminal 1 on the board 8, the locking piece 5 and the fixing piece 6 are inserted into the circular hole 9 and the rectangular hole 10, respectively, and the locking piece 5 protruding from the board 8 is inserted into the circular hole 9 and the rectangular hole 10, respectively. This is done by fixing the root side of the fixing piece 6 to the back surface of the board 8 by soldering s.

The locking piece 5 is press-fitted into the circular hole 9 through its tapered tip to temporarily fix the terminal 1 to the board 8, and the upright piece 2 holds the terminal 1 to the board 8.
When installing the terminal 1, it can be held by hand, making it possible to assemble the terminal 1 more effectively.

6 and 7, the board 8 is provided with a hole 9a into which the locking piece 5 of the terminal 1 is inserted, and an end 10a for positioning the fixing piece 6. After press-fitting the locking piece 5 into the hole 9a while positioning with is fixed to the substrate 8. Further, in FIG. 8, the terminal 1 is not only fixed to the substrate 8, but also has its connection hole 7 fitted into a cut-and-raised part 11, and is fixed by soldering s to that part. In this case, the notch 4 provided in the upright piece 2 of the terminal 1 is used as a connection hole for the lead L, etc.

In the above embodiment, the lead wire L is connected to the terminal 1.
In addition to being connected to the connection hole 7 of the holder, it can also be attached to the notch 4 provided in the upright piece 2, as shown in FIG. This is advantageous when connecting a plurality of lead wires L.

As explained above, according to the present invention, the terminal body is formed of a vertically erected upright piece and a horizontally extended mounting piece, and a part of the upright piece is bent and hangs to attach to the board. Since a locking part is formed and a part of the mounting piece is bent and suspended approximately parallel to the locking part to form a fixing part to the board, it can be mounted to the board without any special fitting process. , it is sufficient to solder the locking part and the fixing part, which can significantly reduce the number of processing steps, and it can be done in the same process as the assembly process of other parts, which has the advantage of extremely excellent workability and productivity. has.

In addition, the dimensions of the locking part and the fixing part can be arbitrarily set according to the thickness of the board, and it can be used even with a large board without special processing, making it highly versatile.
