従来よりIC素子等の電子部品を実装する場合に使用されるICソケット用コ ンタクトピンの内、板厚の薄いコンタクトピンを形成し得るものとして、特開6 1−150249号等に示されるような環状のコンタクトピンが知られているが (図9)、図10及び図11のようにソケット本体20に多数列設したコンタク トピンI0,の頂部3に載接されたIC素子のリード端子は、軸23を介してソ ケット本体20に枢支されている蓋体21が閉合することにより、該蓋体21に 固設されたパッド21−1,21−2によって押圧されてコンタクトピン10’ に圧接せしめられるようになっている。 An IC socket socket traditionally used to mount electronic components such as IC elements. Among contact pins, JP-A-6 Annular contact pins such as those shown in No. 1-150249 are known. (Fig. 9), Fig. 10, and Fig. The lead terminals of the IC element mounted on the top 3 of the top pin I0 are connected to the socket via the shaft 23. By closing the lid body 21 which is pivotally supported on the container body 20, the lid body 21 is closed. The contact pin 10' is pressed by the fixed pads 21-1 and 21-2. It is designed so that it can be pressed into contact with the

しかしながら、かかる従来のコンタクトピン10′では、蓋体21を閉合して 、蓋体21に固設されたパッド21−1,21−2による押圧力でリード端子と 、コンタクトピン10′との接続を図ろうとした場合、リード端子とコンタクト ピン10′との表面に形成された酸化皮膜が絶縁材となって電気的接続が得られ ないといった問題が生じていた。 However, in such a conventional contact pin 10', the lid body 21 is closed. , the lead terminal and , when attempting to connect with contact pin 10', the lead terminal and contact The oxide film formed on the surface of the pin 10' acts as an insulating material to establish an electrical connection. There was a problem that there was no.
【0004】 更に、本考案によるコンタクトピンは極めて簿い板材を環状に形成したもので あるから、大規模な塑性変形には極めて弱いといった欠点を有していた。0004 Furthermore, the contact pin according to the present invention is made of an extremely cheap plate material formed into an annular shape. Therefore, it had the disadvantage of being extremely weak against large-scale plastic deformation.
【0005】 本考案では、かかる実情に鑑み、リード端子やコンタクトピン表面に形成され がちな酸化皮膜による絶縁性もなく電気的接続が得られ、しかも塑性変形によっ て破損することのない極めて板厚の薄いICソケット用コンタクトピンを提供す ることを目的とする。[0005] In view of this situation, the present invention has developed a Electrical connection can be obtained without the insulation caused by oxide film, which is often caused by plastic deformation. We provide contact pins for IC sockets that are extremely thin and will not be damaged due to The porpose is to do.

本考案によるコンタクトピン10を図3に基づいて説明すれば、載接部3に上 方から矢印方向に力Fを加えると、一点鎖線で示すような動作となるが、この動 作の中心を解析すると0点となり、この0点はコンタクトピン10の環状の形状 からわずかばかり外方に離れた処にある。 If the contact pin 10 according to the present invention is explained based on FIG. When force F is applied in the direction of the arrow from When the center of the contact pin 10 is analyzed, it becomes 0 point, and this 0 point is the annular shape of the contact pin 10. It is located slightly outward from the
【0007】 同じように他の形状を比較してみると、図4では一枚の板状から成るコンタク トピン10であるが、力Fによる接触部のワイピング動作の中心Oはコンタクト ピンの形状内にあり、更に図5及び図6のように環状アームの一部を切り欠いた 場合でもワイピング動作の中心Oは、前記一枚板と同様実質的にコンタクトピン の形状内に存在する。[0007] Comparing other shapes in the same way, Figure 4 shows a contact made of a single plate. top pin 10, the center O of the wiping operation of the contact part due to force F is the contact It is in the shape of a pin, and a part of the annular arm is cut out as shown in Figures 5 and 6. Even in this case, the center O of the wiping operation is essentially the contact pin as in the case of the single plate. Exists within the shape of .
【0008】 これをワイピング(こする)量と歪み量をそれぞれ横軸、縦軸に取ってグラフ に示すと図8のような関係になり、環状でしかも二本のアームから成る本考案に よるコンタクトピン10が最も歪み量が大きい反面ワイピング量が小さい値を得 る。この場合、図9のように頂部3が直線状に下方移動しワイピング量が0であ ってはならない。[0008] This is graphed with the amount of wiping (scraping) and amount of distortion on the horizontal and vertical axes, respectively. The relationship shown in Figure 8 is shown in Figure 8, and the present invention is annular and has two arms. Contact pin 10 has the largest amount of distortion, but has the smallest amount of wiping. Ru. In this case, as shown in Fig. 9, the top portion 3 moves downward in a straight line and the wiping amount is 0. It should not be.
【0009】 更に、過大な力Fがコンタクトピン10の頂部3に加えられた場合に起こる塑 性変形によって破損を防止しようとする場合、図7のように環状内部に規制部材 を配設することによつて首部1に発生する変形等を防ぐことが可能となる。[0009] Furthermore, the plasticity that occurs when excessive force F is applied to the top 3 of the contact pin 10 When trying to prevent damage due to sexual deformation, a regulating member is installed inside the annular shape as shown in Figure 7. By arranging this, it becomes possible to prevent deformation or the like occurring in the neck portion 1.
【0010】0010
本考案によれば、蓋体を閉合する際パッドによって生ずる押力の歪みは、図2 に示すように二本のアームに相反する力のベクトルが仂くことにより歪み量は大 きく、しかも接触部のワイピングを確実に行なうことができる。更に過大な力に よるアクシデントに対しても環状内部に規制部材100を配設したから必要以上 に歪む心配がない。 According to the present invention, the distortion of the pushing force caused by the pad when closing the lid body is As shown in the figure, the amount of distortion is large due to the opposite force vectors being applied to the two arms. This makes it possible to wipe the contact area reliably. Even more excessive force In order to prevent accidents caused by There is no need to worry about distortion.
【0011】[0011]
図Iは、本考案によるコンタクトピン10を示しているが、図2のように上方 から力Fを加えられても、二本のアームが上方位置、下方位置に力を分散し合う ので、板厚の薄いコンタクトピンでも捩れたり、倒れたりすることはない。しか も、ワイピング(こすれ)動作の中心が形状外にわずかばかり離れているので歪 み量は大きくとも、ワイピング量としては小さく、益々多端子化傾向にあるショ ートタイプのリードフレームには最適である。 Figure I shows the contact pin 10 according to the invention, with the upper Even if a force F is applied from Therefore, even thin contact pins will not twist or fall. deer However, the center of the wiping (rubbing) motion is slightly away from the outside of the shape, causing distortion. Although the amount of wiping is large, the amount of wiping is small, and the number of terminals is increasing. It is ideal for sheet type lead frames.
【0012】 又、図7のように環状内部の首部1から左縁位置に規制部材(ピン等)100 を配設することによって塑性変形による破損を防止することが可能となる。0012 Also, as shown in FIG. 7, a regulating member (pin, etc.) 100 is placed at the left edge position from the neck 1 inside the annular shape. By providing this, it is possible to prevent damage due to plastic deformation.

上述のように、本考案のコンタクトピンによれば、板厚が薄くとも捩れたり倒 れたりすることなく、確実にリード端子とのワイピングをなし得、又規制部材の 配設によって塑性変形による破損を防ぐことができる。 As mentioned above, the contact pin of the present invention does not twist or fall even if the plate thickness is thin. It is possible to reliably wipe the lead terminal without causing any This arrangement can prevent damage due to plastic deformation.
