【発明の詳細な説明】 〔産業上の利用分野〕 本発明はリード接触子に関し、特にICの電気的特性試
験を行うコンタクタ内のリード接触子に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead contact, and more particularly, to a lead contact in a contactor for performing an electrical characteristic test of an IC.
従来、この種のリード接触子は、第４図に示すよう
に、先端にIC（図示せず）のリードと接触する接触部２
を有する軸1bと、軸1bが収納され接触部２を押下したと
き軸1bが内壁面に沿って内部に押込まれるケース3bと、
ケース3bの内部に収納され軸1bが押込まれたとき軸1bを
ケース3bの外へ押上げるばね４とを含んで構成されてい
た。Conventionally, as shown in FIG. 4, this type of lead contact has a contact portion 2 at its tip which contacts a lead of an IC (not shown).
A shaft 1 b having a Murrell casing 3 b pushed inside along the inner wall surface shaft 1 b is when the shaft 1 b presses the stored contact portion 2,
Case 3 Axis 1 b housed inside the b has been configured to include a shaft pushed Gerubane 4 1 b to the outside of the case 3 b when was pushed.
このようなリード接触子を用いたコンタクタ（図示せ
ず）に測定すべきICを挿入すると、ICのリードの先端は
軸1bの先端の接触部２に圧接するようになる。When inserting such IC to be measured to the lead contacts the contactor used (not shown), the tip of the IC leads become pressed against the contact portion 2 of the end of the shaft 1 b.
上述した従来のリード接触子は、接触部がICのリード
と接触するときリードの先端部が接触部の上面と点接触
になるので、電気的特性試験を行う場合接触不良を発生
するという欠点がある。The conventional lead contact described above has the disadvantage that when the contact part comes into contact with the lead of the IC, the tip of the lead makes point contact with the upper surface of the contact part. is there.
本発明のリード接触子は、先端にICのリードとの接触

構成される。A lead contactor according to the present invention includes a shaft having a contact portion with an IC lead at a tip thereof, a case in which the shaft is housed and the shaft is pushed along an inner wall surface when the contact portion is pressed, and A contact piece that presses against the lead with the lead interlocked with the pressing of the portion, and a spring that is housed in the case and pushes the shaft outward when the shaft is pushed in. .
次に、本発明について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.
第１図は本発明の一実施例の断面図である。 FIG. 1 is a sectional view of one embodiment of the present invention.
第１図に示すように、先端に接触部２を有する軸１
と、軸１が収納され接触部２の押下により軸１が内壁面
に沿って押込まれる一端が開口し他端が密閉された中空
円筒状のケース３と、ケース３の内部に収納され軸１が
押込まれたとき軸１をケース３の開口方向へ押上げるば
ね４と、ケース３の開口側の先端に設けられ接触部２の
押下に連動して先端が内側に傾き挿入されたICのリード
を挟んで押圧する弾性材の接触片５と、接触部２がばね
４で初期位置に戻ったとき接触片５を初期状態に戻すケ
ース３内に収納されたばね６とを含む。As shown in FIG. 1, a shaft 1 having a contact portion 2 at the tip end
And a hollow cylindrical case 3 in which one end is opened and the other end is closed, and the shaft 1 is housed inside the case 3 and the shaft 1 is housed and the contact portion 2 is pushed down to push the shaft 1 along the inner wall surface. A spring 4 for pushing the shaft 1 in the direction of opening of the case 3 when the member 1 is pushed in, and an IC provided at the tip of the case 3 on the opening side and having the tip inclined inward in conjunction with the depression of the contact portion 2 and inserted. The spring includes a contact piece made of an elastic material for pressing the lead therebetween and a spring housed in a case returning the contact piece to an initial state when the contact portion returns to an initial position by the spring.
すなわち、軸１の先端の接触部２の外周に接触片５が
設けられていて、図示しないICのリードで接触部２が押
下され、従って、軸１がケース３内に押込まれたとき、
接触部２の下面が接触片５の底面を押すことにより、接
触片５の先端部が内側へ傾きリードを挟むようにしてリ
ードに圧接する。ばね６は接触片５の復帰用であり、
又、ばね４は軸１の復帰用である。That is, the contact piece 5 is provided on the outer periphery of the contact portion 2 at the tip of the shaft 1, and when the contact portion 2 is pressed by the lead of the IC (not shown), and when the shaft 1 is pushed into the case 3,
When the lower surface of the contact portion 2 presses the bottom surface of the contact piece 5, the tip of the contact piece 5 tilts inward and presses against the lead so as to sandwich the lead. The spring 6 is for returning the contact piece 5,
The spring 4 is for returning the shaft 1.
第２図は第１図の実施例を用いたコンタクタの断面図
である。FIG. 2 is a sectional view of a contactor using the embodiment of FIG.
第２図において、リード接触子10はコンタクタ11内に
内蔵される。IC12は上部から下方へ押下げられIC12のリ
ードが各々のリード接触子10の中へ挿入され接触をと
る。In FIG. 2, a lead contact 10 is built in a contactor 11. The IC 12 is pushed down from above and the leads of the IC 12 are inserted into each lead contact 10 to make contact.
第３図は本発明の第２の実施例の断面図である。 FIG. 3 is a sectional view of a second embodiment of the present invention.
第３図に示すように、第２の実施例ではケース3aの先
端部に弾性材の接触片5aを形成し、軸1aの先端の接触部
２がケース3aの接触片5aを外方へ押広げている。Third, as shown in figure, in the second embodiment the contact piece 5 a of the elastic member is formed at the tip portion of the casing 3 a, the axis 1 a of the tip contact piece 5 a of the contact portion 2 cases 3 a of Is spreading outward.
ICのリードが接触部２を押下げ軸1aがケース3a内に押
込まれたとき、接触部２がなくなるため接触片5aが弾性
で内側に閉まり、リードを挟んでリードに圧接する。When IC leads pressing axis 1 a of the contact portion 2 is pushed into the case 3 a, the contact piece 5 a the contact portion 2 is eliminated is closed inwardly by resilient and pressure contact with the leading sides of the lead.
第２の実施例では、ケース3aと接触片5aとが一体とな
っているため、より確実な接触性を得ることができると
ともに、構造が簡単になる利点がある。In the second embodiment, since the case 3a and the contact piece 5a are integrated, there is an advantage that more reliable contact can be obtained and the structure is simplified.
以上説明したように本発明は、ICのリードが接触部を
押下げることにより、先端の接触片がリードを挟んで圧
接するので、確実な接触性を得ることができ、従って、
良好な電気的特性試験ができる効果がある。As described above, according to the present invention, when the lead of the IC presses down the contact portion, the contact piece at the tip presses against the lead, so that reliable contact can be obtained.
There is an effect that a good electrical characteristic test can be performed.
