Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a DIP (dual inline package) method for surface mount IC sockets. j) Enables mounting on a breadboard with the same 2.54mm pitch as the IC. This is related to the structure of the conversion adapter.

0002

[Conventional technology]

Conventional techniques in this field include, for example, those shown below. FIG. 4 is a diagram showing an example of the pin arrangement of such a conventional IC socket. As shown in this figure, the pitch of the IC socket is 0.8 mm, and the pins 1 are arranged in a staggered pattern, so it cannot be attached to a commonly used breadboard board with a pitch of 2.54 mm. There wasn't. Incidentally, l ₁ is 14 mm, l ₂ is 1.6 mm, l ₃ is 14 mm, l ₄ is 1.6 mm, l ₅ is 8 mm, l ₆ is 1 mm in diameter, and l ₇ is 0.8 mm.

0003 Therefore, conventionally, as shown in FIG. 5, an IC socket is attached to the board 2, and the Conversion board with 2.54mm pitch through holes 3 surrounding it was used.

0004

[Problem that the idea aims to solve]

However, in the conventional configuration described above, the converted through holes are aligned in a row. Because they are lined up, the board itself becomes larger, and when incorporated into a circuit, the circuit also becomes larger. There was a problem that it could become. Also, the IC socket itself is larger than the IC itself, and Since the conversion board is larger than the socket, the connection between the IC itself and the components to be connected is There was a fatal problem that the distance was extremely long and the electrical characteristics deteriorated.

[0005] The present invention eliminates the above problems and uses a socket that is approximately the same size as an IC socket and has a pin socket. We provide conversion adapters that can perform multiple conversions and have good electrical characteristics. The porpose is to do.

[0006]

[Means to solve the problem]

In order to achieve the above object, the present invention uses pins of the narrow pitch IC socket 30. In the adapter that converts to the pitch of a wide pitch breadboard 10, after conversion The through holes 25 and 26 are arranged within the projection range of the IC socket 30, and Part 26 of the through holes 25 and 26 is inside the through hole of the IC socket pin. It was designed to be placed in Here, the pitch of the pins of the IC socket is It is a staggered pin arrangement with a substrate of 0.8 mm, and the pitch of the breadboard is The pitch is 2.54 mm.

[0007]

[Effect]

According to the present invention, as described above, SMD (surface mount device: Surfac e Mount Device) IC socket pins at a pitch of 2.54 mm. In the adapter board to be converted, a part of the through hole to be converted is Place it inside the through-hole.

[0008] Therefore, it is possible to convert the pitch with dimensions that are approximately the same as the IC socket. Moreover, the electrical characteristics can be improved.

[0009]

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 shows the fine pitch of pins of a 44-pin IC showing an embodiment of the present invention. Converting to mm pitch, Figure 2 is an exploded top view showing an example of the implementation of the conversion adapter of the present invention. FIG. 3 is an exploded rear perspective view showing an example of mounting the conversion adapter. In addition, In FIG. 2, the wiring part is omitted.

0010 In these figures, 10 is a breadboard, and the breadboard 10 Through holes 11 are arranged at a pitch of 2.54 mm. 20 is a conversion adapter 2.54mm pitch pins protruding downward and placed on the outer periphery. 21, and a pin 23 with a pitch of 2.54 mm located at the center of the inside. . Also, pin 31 of the short IC socket 30 is connected between pin 21 and pin 23. A through hole 22 is arranged. There is a pin 21 on the top surface of the conversion adapter 20. A through hole 25 and a through hole 26 for the pin 23 are formed.

[0011] Therefore, the IC socket 30 connects its pin 31 to the through hole of the conversion adapter 20. 22, connect, and combine. Breadboard the combination. Insert pins 21 and 23 of conversion adapter 20 into through hole 11 of 10, Implement. In that case, the length of pin 31 of IC socket 30 is the length of pin 21 and pin 2. Since the length of pin 31 is quite short compared to the length of 3, the tip of pin 31 is It never reaches the through hole 11. In other words, pin 31 of IC socket 30 is , are not directly connected to the breadboard 10.

0012 That is, the IC socket 30 connects pin 21 and pin 2 via its pin 31 and wiring. 3, and the pins 21 and 23 are connected to the breadboard through the through hole 11. It is connected to the card 10. In this way, the through hole 11 of the breadboard 10 can be used for at least an IC socket. It is placed within the projection range of the IC socket 30, and a part of the pin 31 of the IC socket 30 is inserted. It is also arranged inside the through hole 22.

[0013] Figure 1 shows an example of 44 pins, but the same applies if the number of pins is large or small. With a similar idea, place the through-hole of the breadboard 10 within the projection range of the IC socket. It is possible to arrange 11. Furthermore, the present invention is not limited to the above embodiments, but based on the spirit of the present invention. Various modifications are possible and are not excluded from the scope of the invention.

[0014]

[Effect of the idea]

As explained in detail above, according to the present invention, the size of the IC socket is approximately the same as that of the IC socket. It is possible to convert the pitch and improve the electrical characteristics. I can do that. Even if the number of IC pins changes, the pins of the IC socket can be inserted through the The area inside the hole changes similarly, so it can be applied regardless of the number of pins. Wear.

[0015] Also, the wiring between the through holes and the wiring with the components to be connected on the board are approximately equidistant. Since the distance between the It can be made into a difficult structure.
