Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a circuit component mounting structure in which components are mounted on an IC board, a printed circuit board, or the like.

[Conventional technology]

Generally, in conventional circuit component mounting structures, the terminal 1 used for adjusting the circuit component is comprised of a pair of U-shaped plates 1 having two parallel surfaces, as shown in FIG.

As shown in FIG. 3, each of the U-shaped terminals 1 is attached and soldered to each circuit pattern 31C of the IC board 2 with its lower mounting surface portion la facing each other. Next, the electrical components 4 are placed across each terminal 1 and soldered (O). [Problems to be Solved] However, due to recent advances in circuit technology, the electrical components 4 to be mounted are rapidly becoming dusty. - The number of electrical components 4 and terminals 10 mounted on a single IC board 2 and the like is also increasing as the density of circuit boards increases.

However, since the conventional terminals 1 are separated in pairs, they are difficult to handle when miniaturized, and there are few parallel surfaces that come in contact with the board 2, so they are mounted in an unstable manner, so the terminals 1 may fall over when soldering. There is a problem in that the soldering process may cause misalignment or misalignment, which may cause soldering defects. Further, the height of the terminal 1 itself is too high, which causes the problem that the thermal stress relieving effect of the If terminal 1 is halved.

[Means for solving problems]

The present invention solves the above problems, and provides a circuit component aesthetic structure in which an IC board and an electric component are connected via a pair of opposing U-shaped terminals, in which the pair of opposing U-shaped terminals are provided. Corresponding sides are connected in advance by a connecting plate part, and after each corresponding other side is attached to the IC board, the connecting plate part is cut off to separate the pair of U-shaped terminals. It is.

〔Example〕

Next, an example thereof will be explained with reference to FIG.

FIG. 1 is a perspective view of an example of a terminal applied to an embodiment of a circuit component mounting structure according to the present invention, and in the figure, the same parts as in FIG. 2 are given the same reference numerals.

In the figure, the terminals 5 are similar to the conventional example in that a pair of U-shaped terminals 1t are prepared, but differ in that the corresponding upper sides of the opposing terminals 1 are integrally connected by a connection g6. Incidentally, constricted portions 7 are formed on both sides of the connecting portion 6, respectively.

Next, the installation will be explained. As shown in FIG. 3, the terminals 5 are soldered to the respective circuit patterns of the IC board 2 at the mounting surface 1a of each terminal 1, as shown in FIG. As a result, a pair of U-shaped terminals 1 facing each other are formed in exactly the same way as in the case of FIG. 3, and then the electrical components 4 can be mounted in the same manner.

According to this, since each terminal 1 is integrated via the connecting part 6 when attached to the IC board 2, it is relatively large and easy to handle, and has a stable shape with many parallel surfaces in contact with the IC board 2. It will be installed in Therefore, good soldering can be performed without the terminal 1 falling over or being misaligned. Furthermore, the height of the terminal 5 can be increased, and the effect of thermal stress can be alleviated. Furthermore, since the fin portion 7 is provided, the connection [6] can be easily separated.

〔effect〕

As explained above, in the present invention, a pair of opposing ;-shaped terminals are connected in advance by a connecting plate part, and after the mounting surface part of each U-shaped terminal is attached to a board, the connecting plate part is removed. Because of this, small U-shaped terminals can be easily handled with appropriate size, and since the parallel surface that contacts the board is large, it can be mounted relatively stably on the board, which prevents the terminal from falling over and prevents the terminal from falling. Alleviation of heat stress effect by securing height,
The terminals can be easily handled, and the number of terminals mounted is also reduced, making it easier to harvest canes.
