Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a terminal fitting for a socket for an integrated circuit.

``Prior Art'' As is well known, an integrated circuit is mounted on a printed circuit board through a plate-shaped socket body made of synthetic resin. A terminal fitting is fitted into each hole.

This terminal fitting is made by fitting a pair of products into a hole in opposing positions and inserting a terminal piece of an integrated circuit into the opposing contact area, but for the purpose of cost reduction, it is preferable to use only one terminal fitting. is also being considered.

That is, the tip of the terminal fitting is curved, the curved part is fitted into the inner surface of the hole in elastic contact, and the terminal piece of the integrated circuit is inserted into the hole from above and held between the inner surface of the hole and the terminal fitting. hold it.

In such a configuration, the hole has an inclined surface with an upper inner surface facing upward so that the terminal piece of the integrated circuit can be easily inserted from above, and the lower end of the terminal piece of the integrated circuit It comes into contact with the inclined surface and descends while being guided, and enters into a position between it and the terminal fitting.

During this insertion, the lower end of the terminal piece of the integrated circuit may scrape the inclined surface of the hole in the synthetic resin socket body, albeit slightly, and this shavings may form between the terminal piece and the terminal fitting. This caused the metal to get inside and cause poor contact.

"Problems to be Solved by the Invention" This invention is a terminal fitting for an integrated circuit socket that was devised to eliminate the above-mentioned conventional drawbacks and inconveniences, and the lower end of the terminal piece of the integrated circuit is scraped off when inserted. The purpose is to prevent shavings from entering between the terminal piece and the terminal fitting.

"Means for Solving the Problems" The present invention provides a terminal fitting 6 that is fitted into a hole 2 formed in a socket body 1 for an integrated circuit, and the terminal fitting 6 is made of a thin metal plate. The piece is formed,
a curved portion 10 that is curved and faces the inner surface of the hole 2;
A leg piece 11 is bent toward the inner surface of the hole 2 and protrudes from both sides of the curved portion 1 to make elastic contact with the inner surface of the hole 2.
0 and the inner surface of the hole 2, and furthermore, the width of the curved portion 10 is set to be smaller than the width of the terminal piece 12 of the integrated circuit inserted between the inner surface of the hole 2 and the inner surface of the hole 2 from above. It has a slightly larger configuration.

"Function" In the above-described configuration, when the terminal fitting 6 is inserted into the hole 2, the legs 11 on both sides of the curved portion 10 are bent toward the opposing inner surface of the hole 2. The tip of the leg piece 11 comes into elastic contact with the inner surface of the hole 2, and a gap corresponding to the rising width of the leg piece 11 is formed between the inner surface of the hole 2 and the surface of the curved part 10.

Therefore, even if the terminal piece 12 of the integrated circuit is inserted from above the hole 2 and the lower end of the terminal piece 12 scrapes the inclined surface 4 of the hole 2, this scraping will fall downward from the gap and the terminal The piece 12 is held between the inner surface of the hole 2 and the surface of the curved portion 10, and there is no risk of shavings entering.

Note that since the width of the curved portion 10 is slightly larger than the width of the terminal piece 12 of the integrated circuit, the terminal piece 12 reliably abuts against the surface of the curved portion 10 and is electrically conductive.

"Embodiment" In the illustrated embodiment, first, the hole 2 drilled in the socket body 1 has a square hole shape, one of the opposing surfaces is a vertical surface 3, and the lower part of the other surface is also vertical. This configuration has a surface 5 and an inclined surface 4 formed above the vertical surface 5.

On the other hand, in the terminal fitting 6, the abutting part 8 continuous with the upper end of the leg part 7 extending downward of the socket main body 1 is provided facing the one vertical surface 3, and is inverted at the upper end of the abutting part 8. A bent portion 9 is formed, and a portion facing the other lower vertical surface 5 is formed as the curved portion 10.

As mentioned above, the leg pieces 11 are provided protruding from both sides of the curved portion 10, and the protruding height thereof is about 0.15 to 0.2 mm.

There are many ways to form this leg piece 11, but since it is made to protrude in the opposite direction to the bending direction of the curved portion 10, it would be effective to form it by ironing, for example, by eyeloning. .

"Effect of the invention" The present invention has the structure and functions as explained above.

Therefore, from above the hole 2, the terminal piece 12 of the integrated circuit is
the lower end of the terminal piece 12 is on the inclined surface 4 of the hole 2.
Even if the shavings are scraped, the shavings will fall downward from the gap, and the terminal piece 12 will be sandwiched between the inner surface of the hole 2 and the surface of the curved part 10, and there is no risk of the shavings entering. There is no possibility of poor contact.

Therefore, according to the terminal fitting of the integrated circuit socket of the present invention, the operation of assembling the terminal piece 12 is easy;
It has many excellent functions and effects, such as no poor contact due to shavings, simple structure, and easy molding.
