Description

[Detailed explanation of the invention] (Industrial application field) This invention is an IC socket (Shrink package).
It is related to contacts used in connectors, etc.

(Prior art) Conventionally, this type of contact was
There are those described in No. 49292 and Japanese Utility Model Application Publication No. 58-154574. In each of these, as shown in FIG. 5, the widthwise central portion B of the strip conductor A is punched out and divided into three parts, a terminal C and two clamping pieces D and E.

(Problem that the invention aims to solve) In recent years, housings into which contacts are inserted have become smaller and smaller due to demands for smaller connectors and higher density mounting, and the width of contact insertion holes in housings has also become smaller. . Therefore, the width of the contact inserted into the contact insertion hole must also be reduced.

However, the conventional contact shown in Fig. 5 is divided into three parts, consisting of terminal C and clamping pieces D and E on both sides. The width is also narrower. However, since the width of the terminal C cannot be made very narrow considering that it will be dipped, the width of the clamping pieces D and E must be made narrower. However, if this width becomes too narrow, the mechanical strength will decrease, so it cannot be made too narrow.
For this reason, there is a limit even if the width of the contact can be made narrower.

(Purpose of the invention) An object of the invention is to provide a contact that can be made narrow in width and has strong mechanical strength even if the width is made somewhat narrow.

(Means for Solving the Problems) As shown in FIG. 1, in the contact of the present invention, the upper part 1a and the lower part 1b of the strip conductor 1 in the longitudinal direction are not divided, and only the central part 1c is separated in the width direction of the conductor 1. One divided piece 2 is used as a terminal, and the other divided piece 3 has its horizontally bent part 3a bent outward from the base 3e of the divided part, and the vertically bent part 3b beyond that is bent upward. , the folded part 3c which is not divided and has the same width as the upper part 1a of the strip conductor 1 is folded back downward to the upper part 1a side, and this folded part 3c and the same upper part 1a
An insertion portion 6 is formed between the two and into which a terminal of an electronic component can be inserted and clamped.

(Function) To use the contact 10 of the present invention, as shown in FIG. Locking protrusion 5a
is press-fitted and secured to the inner wall surface of the housing 11. Then, insert the terminal (split piece) 2 of the contact 10 into the through hole 21 of the printed circuit board 20 as shown in FIG.
When the terminal 31 of the IC component 30, for example, is inserted into the insertion part 6 of the contact 10 shown in FIG. be done.

(Embodiment) Figures 1 to 4 are explanatory diagrams of the contact of the present invention. As shown in Figure 1, the upper and lower parts 1a and 1b of the strip conductor 1 are left as they are without being divided, and a vertical cut is made only in the center of the longitudinal direction to form two divided pieces 2 and 3. In the contact of Figure 1, the widths of the two divided pieces 2 and 3 are the same, but they do not have to be the same.

As shown in FIGS. 1 and 3, one divided piece 3 has
Ribs 4 are formed that are pushed out toward the band-shaped conductor 1 side. The width, length, extrusion dimension, extrusion direction, etc. of the rib 4 are appropriately selected so that the divided piece 3 has a desired strength.

In FIG. 1, the folded part 3c of the divided piece 3 is folded downward toward the upper part 1a of the strip conductor 1, but the divided piece 3 has a tip end at the end of the folded part 3c as shown in FIG. 3d further vertically bent part 3b
You can also fold it to the side.

(Effects of the invention) The contact of the invention has the following various effects.

(1) Since the strip conductor 1 is divided, the contact is miniaturized, and since it is divided into two parts, the width of the divided pieces 2 and 3 is wider than the conventional contact, which is divided into three parts. The mechanical strength of the divided pieces is strong, and the terminals of inserted IC parts etc. can be securely clamped.

(2) Only the center part in the longitudinal direction of the strip conductor 1 is divided, and the upper part 1 is folded back and faces the opposite part.
Since the width of the strip conductor 1 remains the same as that of the strip conductor 1 without being divided, the terminal 31 such as an IC component can be easily inserted between the upper portion 1a and the lower portion 1b.

(3) The horizontally bent portion 3a and the vertically bent portion 3b are divided into two parts and have a narrow width, so that they are easy to bend and can be easily bent during contact manufacturing.

Claims (1)

[Scope of utility model registration request] The longitudinally upper part 1a and lower part 1b of the strip conductor 1 are not divided, and only the central part 1c is divided into two parts in the width direction of the conductor 1. One divided piece 2 is used as a terminal, and the other divided piece 3 is used as a terminal. The bent portion 3a is bent outward from the base 3e of the divided portion, and the vertically bent portion 3b beyond that is bent upward, and the folded portion beyond that is undivided and has the same width as the upper portion 1a of the strip conductor 1. 3c is folded downward toward the upper part 1a, and an insertion part 6 is formed between the folded part 3c and the upper part 1a, into which a terminal of an electronic component can be inserted and clamped.
