Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching terminals for connecting printed circuit boards to each other, for example.

[0002]

2. Description of the Related Art In recent electronic devices such as tuners, for example, as shown in FIG. 5, each circuit unit is unitized for each printed circuit board 100, and a plurality of circuit boards for connecting these printed circuit boards 100 are connected. Some terminals 101 are inserted and fixed on a printed circuit board.

A terminal 101 which is inserted into and fixed to the printed circuit board 100 is bent at one end into a substantially L shape to form leg pieces 102, and the leg pieces 102 are respectively formed on the printed board 100. The printed circuit board 10 is inserted into the leg piece mounting holes 103 corresponding to
It has a structure in which the back side of 0 is soldered.

In such a printed circuit board 100, first, as shown in FIG. 6, another electronic component 110 is mounted, and the other end opposite to each leg 102 is integrally connected by a tie bar 104. The terminal member string 105 is prepared, and the leg pieces 102 of the terminals 101 corresponding to the leg piece mounting holes 103 preliminarily drilled in the printed circuit board 100 are inserted, and molten solder is accumulated on the back surface side of the printed circuit board 100. By immersing each leg 102 in the solder bath, the printed circuit board 100
Then, the tie bars 104 are cut off along the alternate long and short dash line shown in FIG. 7 to separate the individual terminals 101.

[0005]

However, in the printed circuit board 100 as described above, the leg pieces 1 of each terminal 101 are provided.
02 corresponds to the leg piece mounting hole 103 of the printed circuit board 100.
When the tie bar 104 is cut off and divided into the individual terminals 101 after being inserted and fixed to the terminals 101, the terminals 101 inserted and fixed to the leg mounting holes 103 formed in the printed circuit board 100 are fixed.
Since the tip end side is a free end from the root portion of the leg piece 102, there is a problem that bending easily occurs from the root portion of the terminal 101 in the printed circuit board 100.

When each terminal 101 is bent at the root portion of the leg piece 102 in this way, it is difficult to straighten each terminal 101, and, for example, if a misalignment occurs with the connection site of the other printed circuit board 100. It becomes impossible to connect,
If the bending of the terminal 101 is to be corrected on the spot, it takes time and labor, which is disadvantageous in terms of cost.

Further, as a means for connecting the printed circuit boards to each other, there is a means for directly soldering and fixing by using a lead wire (not shown) or the like, but it is time-consuming and disadvantageous in cost.

Further, the means for connecting the concavo-convex connectors (not shown) attached to the printed board 100 can easily connect both boards, but there is a problem that the connector itself becomes expensive.

[0009]

In order to solve the above-mentioned problems, in the first terminal connecting structure to the printed circuit board of the present invention, two or more leg pieces bent at one end side of the terminal are respectively formed. It is characterized in that it is inserted and fixed in a leg piece mounting hole punched in the printed circuit board, and the terminal mounting structure to the second printed circuit board has two or more leg pieces in a parallel positional relationship. Each of the leg pieces of the bent terminal is inserted and fixed in each leg piece mounting hole punched in the printed circuit board corresponding to the leg pieces. In the terminal mounting structure to the printed circuit board of, at least one leg of each of the two or more legs is bent at a right angle relative to the other leg, and each leg of the terminal is bent. , It must be inserted and fixed in each leg mounting hole of the printed circuit board punched corresponding to these legs. And it features.

[0010]

In the terminal mounting structure for the printed circuit board according to the present invention,
Two or more leg pieces are bent on one end side of the terminal, and leg piece mounting holes are punched on the printed circuit board corresponding to each leg piece,
The leg piece 102 of each terminal 101 is inserted into the leg piece mounting hole.
By inserting and fixing, the terminals 101 located in the printed circuit board are less likely to bend, and the connection with the adjacent printed circuit board can be ensured.

Further, since each of the two or more leg pieces of each terminal is bent in a parallel positional relationship,
Terminals are fixed to the printed circuit board at two or more points, are reinforced by minimizing movement in the front-back direction, and at least one leg is bent at a right angle relative to the other leg. And, the movement in the front, rear, left and right directions is suppressed and reinforced,
There is no need to worry about bending around the terminal legs.
