Description

[Detailed description of the invention] [Field of industrial application] The present invention provides a lead for a hybrid integrated circuit in which one end of a plurality of terminal pins is connected via a connecting part, and the other ends are bent in the same direction at a substantially right angle. Regarding.

[Conventional technology]

FIGS. 5 to 8 are diagrams for explaining conventional leads for hybrid integrated circuits. 5 and 6, reference numeral 1 denotes a comb-shaped lead for a hybrid integrated circuit, in which a plurality of terminal pins 2 are arranged in one direction at a predetermined interval, each connected at one end via a connecting part 3. are connected. Further, the other ends of the terminal pins 2 are each bent approximately at right angles in the same direction from a predetermined length to form a fixing portion 4. Reference numeral 5 denotes a hybrid integrated circuit board, on one side of which a conductor pattern is formed, and a plurality of electronic components 6 such as surface-mounted components and leaded components are mounted to form a hybrid integrated circuit 7. The fixing portions 4 of the respective terminal pins 2 are soldered to the terminal portions 8 of the hybrid integrated circuit 7, as shown in FIG.

7 and 8 show a hybrid integrated circuit lead 1 in which the fixing portion 4 of the terminal pin 2 is U-shaped. In addition, the hybrid integrated circuit board 5 can be attached and fixed by the fixing portion 4 so as to be clamped therebetween. Therefore, in this case, the hybrid integrated circuit lead 1 can be soldered together with the electronic component 6 by reflow.

[Problem that the invention attempts to solve]

By the way, in the conventional lead 1 for a hybrid integrated circuit as shown in FIGS. 5 and 6, it is difficult to position the fixing part 4 of each terminal pin 2 and the terminal part 9 of the hybrid integrated circuit 8, and it is difficult to solder. Since the hybrid integrated circuit lead 1 is not fixed to the hybrid integrated circuit board 5 before it is attached, it is not possible to solder it together with the electronic components 7 by reflow, resulting in extremely poor workability and failure. It's the economy.

Furthermore, with conventional leads 1 for hybrid integrated circuits as shown in FIGS. 7 and 8, it is possible to solder them together with electronic components 6 by reflow, but as shown in FIG. The hybrid integrated circuit becomes larger by the thickness of the terminal pin 2 of the integrated circuit lead, and when the hybrid integrated circuit is housed in a case, there is a disadvantage that the hybrid integrated circuit cannot be housed closely in the case. be.

[Means for solving problems]

In order to eliminate the above-mentioned drawbacks, the present invention provides a lead for a hybrid integrated circuit in which one end of a plurality of terminal pins is connected via a connecting part and the other ends are bent in the same direction at a substantially right angle. The present invention provides a lead for a hybrid integrated circuit, characterized in that one of the terminal pins is longer than the other terminal pins by a predetermined distance, and is shifted by a predetermined distance in a direction opposite to the bending direction.

[Effect]

Since the present invention has the above structure,
The hybrid integrated circuit board can be attached so as to be sandwiched between the two types of terminal pins, and the terminal pins can be fixed inside the board.

〔Example〕

FIGS. 1 to 4 are diagrams for explaining one embodiment of the present invention. In these figures, a plurality of terminal pins 2 are arranged in one direction at predetermined intervals.
The lengths up to the terminal pins are alternately long and short, and the lengths of the long terminal pins are longer than the lengths of the short terminal pins by approximately the thickness of the hybrid integrated circuit substrate 5. Further, each of the long terminal pins 2 is bent in the vicinity of the connecting portion 3 so as to be shifted by a predetermined distance in a direction opposite to the fixing portion 4. Therefore, as shown in FIGS. 2 and 3, each fixing part 4 and the terminal part 8 are aligned with each other until the end of the hybrid integrated circuit 7 is stopped between the fixing parts 4 of the hybrid integrated circuit lead. When inserted, the fixing part 4 and the terminal part 8 of the hybrid integrated circuit can be positioned, and at the same time, the short terminal pin 2 can be fixed at a position a predetermined distance from the end of the hybrid integrated circuit 7. . In this state, the long terminal pins 2 are removed from the hybrid integrated circuit by soldering the terminal pins 2 together with the electronic components 6 by reflow, and then cutting and removing the connecting portions 3, as shown in FIG. Short terminal pin 2, which is the original terminal pin, as shown in
Only the leads remain as leads for hybrid integrated circuits. As a result of this, the terminal pins 2 of the hybrid integrated circuit lead 1 are connected inward from the terminals of the hybrid integrated circuit 7 by a predetermined distance, so the hybrid integrated circuit 7 can be stored closely in the case, making it compact. can be converted into

In the above embodiment, a case has been described in which adjacent terminal pins alternately sandwich both sides of the hybrid integrated circuit board, but any shape capable of holding both sides of the hybrid integrated circuit board may be used. The present invention can be implemented without being limited to the above embodiments.

[Effect of idea]

As described above, the present invention provides a lead for a hybrid integrated circuit in which one end of a plurality of terminal pins is connected via a connecting part and the other ends are bent in the same direction at a substantially right angle. A lead for a hybrid integrated circuit is characterized in that the terminal pin is longer than other terminal pins by a predetermined distance, and is shifted by a predetermined distance in a direction opposite to the bending direction. Since the present invention has such features, it is possible to easily position the hybrid integrated circuit lead and the hybrid integrated circuit board. Further, the hybrid integrated circuit can be housed in close contact with the case, and the size can be reduced.
