Description

この発明は、半導体装置（以下「ＩＣパッケージ」という）等の電気部品を収容する電気部品用ソケット、特に、電気部品を押圧するラッチが設けられた電気部品用ソケットに関するものである。   The present invention relates to an electrical component socket for housing an electrical component such as a semiconductor device (hereinafter referred to as an “IC package”), and more particularly to an electrical component socket provided with a latch for pressing the electrical component.

従来から、この種の「電気部品用ソケット」としては、例えば特許文献１に記載されたようなＩＣソケットがある。すなわち、この特許文献１の要約書の［解決手段］の欄には、「ＩＣパッケージを収容するソケット本体にコンタクトピンが設けられると共に、ＩＣパッケージを押圧するラッチが回動自在に設けられ、このラッチを作動させる操作部材がソケット本体に対して上下動自在に設けられたＩＣソケットにおいて、操作部材には、下降時にラッチを開く方向に回動させる開き用作動部と、上昇時にラッチを閉じる方向に回動させる閉じ用作動部とを形成し、ラッチには、ＩＣパッケージを押圧する押圧部と、開き用作動部にて押圧される開き用被押圧部と、閉じ用作動部にて押圧される閉じ用被押圧部とを有する。」旨開示されている。   Conventionally, as this type of “electrical component socket”, for example, there is an IC socket as described in Patent Document 1. That is, in the [Solution means] column of the abstract of this Patent Document 1, “a contact pin is provided on the socket body that accommodates the IC package, and a latch that presses the IC package is provided rotatably. In an IC socket in which an operating member for operating the latch is provided so as to be movable up and down with respect to the socket body, the operating member includes an opening operating portion that rotates in a direction to open the latch when lowered, and a direction that closes the latch when raised The latch is pressed by the pressing portion that presses the IC package, the pressing target portion that is pressed by the opening operating portion, and the closing operating portion. And a pressed portion for closing. ”.

これによれば、「ラッチ作動専用のばねが必要なく、ばねの装着場所の確保や必要圧力の計算などの設計工数、又、製品製作の際の部品費用、組立工数等が必要なく、設計不具合、組立不具合の要素をなくすことができ、高品質の製品を製作できる。」旨記載されている。
特開２００４−１４１３３号公報。 According to this, there is no need for a spring dedicated to latch operation, no design man-hours such as securing the spring mounting location and calculating the required pressure, and no part costs or assembly man-hours required for product production. The element of assembly failure can be eliminated, and a high-quality product can be manufactured. "
Japanese Patent Application Laid-Open No. 2004-14133.

しかしながら、このような従来のものにあっては、操作部材を上昇させて閉じ用作動部で、ラッチの閉じ用被押圧部を下方から上方へ持ち上げるようにして、ラッチを閉じる方向へ回動させ、この操作部材の最上昇位置で、閉じ用作動部により、ラッチの閉じ用被押圧部を持ち上げた状態で保持しているため、電気部品用ソケットに振動等が作用した場合には、その操作部材が上下動して、ラッチが動いてしまう虞がある。これにより、コンタクトピンとＩＣパッケージとの接触が不安定となり、接触抵抗が不安定になる虞がある。   However, in such a conventional device, the operating member is raised and the closing actuating portion lifts the closing pressed portion of the latch upward from below, and rotates the latch in the closing direction. The operation member for closing holds the pressed portion for closing the latch at the highest position of the operating member, so that when vibration or the like acts on the socket for electrical parts, the operation is performed. The member may move up and down and the latch may move. As a result, the contact between the contact pin and the IC package becomes unstable, and the contact resistance may become unstable.

そこで、この発明は、ラッチ作動専用のばねを用いることなく、部品点数や組立工数の増加並びに、ソケット外形の大型化を招くことなく、ラッチ閉状態で、電気部品を押圧した状態では、ラッチが動かないようにして、コンタクトピンと電気部品との接触安定性を確保する電気部品用ソケットを提供することを課題としている。   Therefore, the present invention does not use a spring dedicated to the latch operation, increases the number of parts and the number of assembly steps, and does not increase the size of the socket. An object of the present invention is to provide a socket for an electrical component that ensures contact stability between the contact pin and the electrical component without moving.

かかる課題を達成するために、請求項１に記載の発明は、電気部品が収容される収容部を有するソケット本体と、該ソケット本体にラッチ軸を介して回動自在に設けられ、閉状態で前記電気部品を押圧し、開状態で前記電気部品の収容・取出し範囲から退避されるラッチと、前記ソケット本体に対して上下動自在に設けられて前記ラッチを回動させる操作部材とを備えた電気部品用ソケットにおいて、前記ラッチは、一端部側に前記電気部品を押圧する押圧部が形成され、中間部が前記ラッチ軸を介して回動自在に設けられ、他端部側に前記操作部材に摺接する***作部が形成され、前記操作部材には、前記ラッチによる前記電気部品の押圧状態である前記閉状態で、前記***作部に当接して前記ラッチの開方向への回動を停止させる略鉛直方向に沿うストッパ壁が形成された電気部品用ソケットとしたことを特徴とする。   In order to achieve such an object, the invention according to claim 1 is provided with a socket main body having an accommodating portion in which an electric component is accommodated, and the socket main body rotatably provided via a latch shaft. A latch that presses the electrical component and is retracted from a range in which the electrical component is accommodated / removed in an open state; and an operation member that is provided to be movable up and down with respect to the socket body and rotates the latch. In the electrical component socket, the latch has a pressing portion that presses the electrical component on one end side, an intermediate portion is rotatably provided via the latch shaft, and the operation member on the other end side. An operated portion that is slidably contacted is formed, and the operating member is in contact with the operated portion and rotates in the opening direction of the latch in the closed state that is a pressed state of the electrical component by the latch. Almost vertical to stop Characterized in that the socket for electrical parts which stopper wall is formed along the direction.

請求項２に記載の発明は、請求項１に記載の構成に加え、前記操作部材が最下降された状態で、前記ラッチの開方向への回動によって、前記ストッパ壁の上端部が、前記ラッチの前記***作部の下面側に入り込み、前記操作部材の上昇時に、前記ストッパ壁の上端部で前記***作部の下面を上方に向けて押圧して、前記ラッチを閉じる方向に回動させるように構成されたことを特徴とする。 According to a second aspect of the present invention, in addition to the configuration according to the first aspect, the upper end portion of the stopper wall is moved by the rotation of the latch in the opening direction with the operation member in the lowest position. The latch enters the lower surface side of the operated portion, and when the operating member is lifted, the upper end portion of the stopper wall presses the lower surface of the operated portion upward to rotate the latch in a closing direction. It was configured as described above.

請求項３に記載の発明は、請求項１又は２に記載の構成に加え、前記ラッチは、閉状態で、前記操作部材から前記***作部への操作力が解除されると、開方向へ回動されるように、前記ラッチの重心位置及び前記ラッチ軸の位置が所定の位置関係に設定されていることを特徴とする。   According to a third aspect of the present invention, in addition to the configuration of the first or second aspect, when the operating force from the operating member to the operated portion is released in the closed state, the latch is moved in the opening direction. The position of the center of gravity of the latch and the position of the latch shaft are set in a predetermined positional relationship so as to be rotated.

請求項１に記載の発明によれば、操作部材には、ラッチによる電気部品の押圧状態である閉状態で、***作部に当接してラッチの開方向への回動を停止させる略鉛直方向に沿うストッパ壁が形成されたため、ラッチ専用のスプリングを配設する必要がなく、部品点数や組立工数の増加並びに、ソケット外形の大型化を招くことなく、ラッチ閉状態で、電気部品を押圧した状態で、ラッチが動かないようにして、コンタクトピンと電気部品との接触安定性を確保することができる。   According to the first aspect of the present invention, the operation member is in a substantially vertical direction in which the operation member is in a closed state, which is a pressing state of the electric component by the latch, and abuts on the operated portion to stop the rotation of the latch in the opening direction. Because the stopper wall along the line is formed, it is not necessary to install a spring dedicated to the latch, and the electrical parts are pressed in the latch closed state without increasing the number of parts and the number of assembly steps and increasing the size of the socket outer shape. In this state, it is possible to ensure contact stability between the contact pin and the electric component by preventing the latch from moving.

請求項３に記載の発明によれば、ラッチは、閉状態で、操作部材から***作部への操作力が解除されると、開方向へ回動されるように、ラッチの重心位置及びラッチ軸の位置が所定の位置関係に設定されているため、ストッパ壁を形成するだけの簡単な構造の改良で、ラッチ専用のばねを用いる必要なく、操作部材の上下動によりラッチの開閉動作を行わせることができる。   According to the third aspect of the present invention, when the latch is in the closed state and the operating force from the operating member to the operated portion is released, the latch is positioned in the center of gravity and the latch so as to rotate in the opening direction. Since the shaft position is set to a predetermined positional relationship, the simple structure improvement that only forms the stopper wall makes it possible to open and close the latch by moving the operating member up and down without using a spring dedicated to the latch. Can be made.

以下、この発明の実施の形態について説明する。   Embodiments of the present invention will be described below.

図１乃至図３には、この発明の実施の形態を示す。   1 to 3 show an embodiment of the present invention.

まず構成を説明すると、図中符号１１は「電気部品用ソケット」としてのＩＣソケットで、このＩＣソケット１１に「電気部品」であるＩＣパッケージ１２を収容することにより、このＩＣパッケージ１２と図示省略の配線基板とをＩＣソケット１１を介して電気的に接続するようにしている。この接続状態で、ＩＣパッケージ１２の性能試験が行われるようになっている。   First, the configuration will be described. Reference numeral 11 in the drawing denotes an IC socket as an “electrical component socket”. By housing the IC package 12 as an “electrical component” in the IC socket 11, the IC package 12 is omitted from the illustration. These wiring boards are electrically connected via the IC socket 11. The performance test of the IC package 12 is performed in this connected state.

このＩＣパッケージ１２は、図３に示すように、いわゆるＱＦＮ(Quad Flat Non-Leaded Package)タイプと称されるもので、方形状のパッケージ本体１２ｂの下面に「端子」としての多数の板状端子１２ｂが四角形の枠形状に配列されている。   As shown in FIG. 3, the IC package 12 is called a so-called QFN (Quad Flat Non-Leaded Package) type, and a large number of plate-like terminals as “terminals” are formed on the lower surface of the rectangular package body 12b. 12b are arranged in a rectangular frame shape.

一方、ＩＣソケット１１は、配線基板上に取り付けられるソケット本体１３を有し、このソケット本体１３に、複数のコンタクトピン１５が配設されると共に、このソケット本体１３にＩＣパッケージ１２が収容されるようになっている。また、この収容されたＩＣパッケージ１２を押圧するラッチ１６がソケット本体１３に回動自在に設けられると共に、このラッチ１６を開閉させる操作部材１７がソケット本体１３に上下動自在に設けられている。   On the other hand, the IC socket 11 has a socket body 13 that is mounted on a wiring board. The socket body 13 is provided with a plurality of contact pins 15 and the IC package 12 is accommodated in the socket body 13. It is like that. A latch 16 for pressing the accommodated IC package 12 is rotatably provided on the socket main body 13, and an operation member 17 for opening and closing the latch 16 is provided on the socket main body 13 so as to be movable up and down.

より詳しくは、そのソケット本体１３は、配線基板上に配設されるベース部１９と、このベース部１９の中央部に配設され、ＩＣパッケージ１２を収容するフローティングプレート２０とを有している。   More specifically, the socket main body 13 includes a base portion 19 disposed on the wiring board, and a floating plate 20 disposed in the central portion of the base portion 19 and accommodating the IC package 12. .

そのベース部１９には、複数のコンタクトピン１５が配設されていると共に、このベース部１９には、ＩＣパッケージ１２と配線基板とを電気的に接続するグランドピン２１が配設されている。   The base portion 19 is provided with a plurality of contact pins 15, and the base portion 19 is provided with ground pins 21 that electrically connect the IC package 12 and the wiring board.

このコンタクトピン１５は、導電性及び弾力性を有する板材から形成され、図２に示すように、ベース部１９に圧入固定される基板部１５ａと、この基板部１５ａから下方に延長されて配線基板に電気的に接続されるリード部１５ｂと、その基板部１５ａから上方に延長されたばね部１５ｃと、このばね部１５ｃの先端部から上方に突設されてＩＣパッケージ１２の板状端子１２ｂに下方から接触されて電気的に接続される接触部１５ｄとを有している。   As shown in FIG. 2, the contact pin 15 is formed of a plate material having conductivity and elasticity. As shown in FIG. 2, the contact portion 15 is press-fitted and fixed to the base portion 19 and is extended downward from the substrate portion 15a. A lead portion 15b electrically connected to the base plate portion 15a, a spring portion 15c extending upward from the substrate portion 15a, and projecting upward from the distal end portion of the spring portion 15c to the plate-like terminal 12b of the IC package 12; A contact portion 15d that is contacted and electrically connected.

また、フローティングプレート２０は、ベース部１９上に上下動自在に案内され、四隅に設けられたコイルスプリング２２により上方に付勢され、ＩＣパッケージ１２が収容される収容部２０ａが形成され、更に、この収容部２０ａの四隅には、そのＩＣパッケージ１２の各角部をガイドするガイド部２０ｂが上方に向けて突設されている。また、このフローティングプレート２０には、コンタクトピン１５の接触部１５ｄが下方から上方に向けて挿入されて上方に露出するように開口２０ｃが形成されている。   Further, the floating plate 20 is guided on the base portion 19 so as to be movable up and down, and is biased upward by coil springs 22 provided at the four corners to form a housing portion 20a for housing the IC package 12, and further, At the four corners of the housing portion 20a, guide portions 20b for guiding the respective corner portions of the IC package 12 are projected upward. The floating plate 20 has an opening 20c so that the contact portion 15d of the contact pin 15 is inserted upward from below and exposed upward.

さらに、ラッチ１６は、左右に一対配設され、ソケット本体１３のベース部１９にラッチ軸２４を介して回動自在に設けられ、閉状態（図２中、中心から左半分に示す）でＩＣパッケージ１２を押圧し、開状態（図２中、中心から右半分に示す）でＩＣパッケージ１２の収容・取出し範囲から退避されるようになっている。   Further, a pair of latches 16 are provided on the left and right sides, and are rotatably provided on the base portion 19 of the socket body 13 via a latch shaft 24, and in a closed state (shown in the left half from the center in FIG. 2). The package 12 is pressed and retracted from the accommodation / removal range of the IC package 12 in an open state (shown in the right half from the center in FIG. 2).

具体的には、ラッチ１６は、一端部側にＩＣパッケージ１２を押圧する押圧部１６ａが形成され、中間部１６ｂがラッチ軸２４を介して回動自在に設けられ、他端部側に操作部材１７に摺接する***作部１６ｃが形成されている。   Specifically, the latch 16 has a pressing portion 16a that presses the IC package 12 on one end side, an intermediate portion 16b that is rotatably provided via a latch shaft 24, and an operating member on the other end side. An operated portion 16 c slidably in contact with 17 is formed.

また、このラッチ１６は、閉状態から***作部１６ｃへの操作力が解除されると、開方向へ回動されるように、このラッチ１６の重心位置及びラッチ軸２４の位置が所定の位置関係に設定されている。なお、ここでは、ラッチ１６専用のスプリングが配設されていない。   Further, when the operating force to the operated portion 16c is released from the closed state, the latch 16 is rotated in the opening direction so that the position of the center of gravity of the latch 16 and the position of the latch shaft 24 are predetermined positions. Set in a relationship. Here, a spring dedicated to the latch 16 is not provided.

一方、操作部材１７は、図１に示すように、略枠形状を呈し、ベース部１９の四隅に突設されたリベット２５により、上下動自在に案内されると共に、四カ所に設けられたコイルスプリング２６により上方に付勢されている。   On the other hand, as shown in FIG. 1, the operation member 17 has a substantially frame shape, and is guided by a rivet 25 protruding from the four corners of the base portion 19 so as to be movable up and down, and is provided with coils provided at four locations. The spring 26 is biased upward.

さらにまた、この操作部材１７には、枠形状の内側面側に略鉛直方向に沿うストッパ壁１７ａが形成され、ラッチ１６によるＩＣパッケージ１２の押圧状態である閉状態で、そのストッパ壁１７ａにラッチ***作部１６ｃの先端１６ｄに当接してラッチ１６の開方向への回動を停止させるように構成されている（図２中、左半分参照）。   Furthermore, the operation member 17 is formed with a stopper wall 17a extending in a substantially vertical direction on the inner side surface of the frame shape, and is latched to the stopper wall 17a when the IC package 12 is pressed by the latch 16. It is configured to abut on the tip 16d of the operated portion 16c and stop the rotation of the latch 16 in the opening direction (see the left half in FIG. 2).

また、ストッパ壁１７ａの上端部１７ｂは、操作部材１７が最下降された状態で、ラッチ１６の***作部１６ｃの下面１６ｅ側に入り込むように構成されると共に、操作部材１７を最下降状態から上昇させる場合には、その上端部１７ｂが***作部１６ｃの下面１６ｅを上方に向けて押して、ラッチ１６を閉じる方向に回動させるように構成されている。   In addition, the upper end portion 17b of the stopper wall 17a is configured to enter the lower surface 16e side of the operated portion 16c of the latch 16 in a state where the operation member 17 is lowered, and the operation member 17 is moved from the lowest lowered state. In the case of raising, the upper end portion 17b is configured to push the lower surface 16e of the operated portion 16c upward and rotate the latch 16 in the closing direction.

次に、かかるＩＣソケット１１の使用方法について説明する。   Next, how to use the IC socket 11 will be described.

ＩＣパッケージ１２をＩＣソケット１１にセットするには、まず、操作部材１７をコイルスプリング２６の付勢力に抗して下方に押し下げる。すると、この操作部材１７のストッパ壁上端部１７ｂが、ラッチ１６の***作部１６ｃの下側に入り込み、ラッチ１６が開く方向に回動される。   In order to set the IC package 12 in the IC socket 11, first, the operation member 17 is pushed downward against the urging force of the coil spring 26. Then, the stopper wall upper end portion 17b of the operation member 17 enters the lower side of the operated portion 16c of the latch 16 and is rotated in the direction in which the latch 16 is opened.

この場合には、ラッチ１６の重心位置及びラッチ軸２４の位置等の関係により、そのラッチ１６は、操作部材１７からの押圧力が解除されると、スプリングの付勢力によらず、開く方向に回動される。   In this case, due to the relationship between the position of the center of gravity of the latch 16 and the position of the latch shaft 24, when the pressing force from the operation member 17 is released, the latch 16 is opened in the opening direction regardless of the biasing force of the spring. It is rotated.

そして、操作部材１７が最下降された状態では、図２中、右半分に示すように、ラッチ１６が最大限開かれて、押圧部１６ａがＩＣパッケージ１２の収容・取り出し範囲から退避される。   In the state where the operation member 17 is lowered to the lowest, as shown in the right half of FIG. 2, the latch 16 is opened to the maximum, and the pressing portion 16 a is retracted from the accommodation / removal range of the IC package 12.

この状態で、ＩＣパッケージ１２をフローティングプレート２０の収容部２０ａ上に収容する。この収容時には、ガイド部２０ｂにより案内されて所定の位置に収容されることとなる。   In this state, the IC package 12 is accommodated on the accommodating portion 20 a of the floating plate 20. At the time of this accommodation, it will guide by the guide part 20b and will be accommodated in a predetermined position.

次に、操作部材１７への押下げ力を解除すると、この操作部材１７は、コイルスプリング２６の付勢力により上昇し、この操作部材１７のストッパ壁上端部１７ｂが、ラッチ１６の***作部１６ｃの下面１６ｅに当接して押し上げられ、ラッチ１６が閉じる方向に回動させられる。   Next, when the pressing force to the operating member 17 is released, the operating member 17 is raised by the urging force of the coil spring 26, and the stopper wall upper end portion 17b of the operating member 17 is operated by the operated portion 16c of the latch 16. The latch 16 is rotated in the closing direction by being pushed up by abutting against the lower surface 16e.

そして、ラッチ１６が閉じ、このラッチ１６の押圧部１６ａで、ＩＣパッケージ１２が押圧されると、フローティングプレート２０がコイルスプリング２２の付勢力に抗して僅かに下降し、コンタクトピン接触部１５ｄとＩＣパッケージ板状端子１２ｂとが所定の接触圧力で接触することとなる。   When the latch 16 is closed and the IC package 12 is pressed by the pressing portion 16a of the latch 16, the floating plate 20 is slightly lowered against the urging force of the coil spring 22, and the contact pin contact portion 15d The IC package plate-like terminal 12b comes into contact with a predetermined contact pressure.

この状態で、ラッチ１６は、***作部１６ｃの先端１６ｄが、略鉛直方向に沿うストッパ壁１７ａに当接されることにより、ラッチ１６は開く方向への回動が停止状態（ロック状態）とされる。   In this state, when the tip 16d of the operated portion 16c is brought into contact with the stopper wall 17a along the substantially vertical direction, the latch 16 is brought into a stopped state (locked state). Is done.

かかるロック状態は、ＩＣソケット１１に振動が加わり、操作部材１７が多少上下動した場合でも、ラッチ１６の***作部１６ｃの先端１６ｄが、操作部材１７の鉛直方向に沿うストッパ壁１７ａを摺動するだけであるため、ロック状態が維持されることから、ラッチ１６の回動を防止できる。   In this locked state, even when vibration is applied to the IC socket 11 and the operation member 17 moves up and down somewhat, the tip 16d of the operated portion 16c of the latch 16 slides on the stopper wall 17a along the vertical direction of the operation member 17. Therefore, since the locked state is maintained, the latch 16 can be prevented from rotating.

してみれば、ラッチ１６専用のスプリングを配設する必要がないため、部品点数や組立工数の増加並びに、ソケット外形の大型化を招くことなく、ラッチ１６閉状態で、ＩＣパッケージ１２を押圧した状態で、ラッチ１６が動かないようにして、コンタクトピン１５とＩＣパッケージ１２との接触安定性を確保することができる。   As a result, since there is no need to provide a spring dedicated to the latch 16, the IC package 12 is pressed in the closed state of the latch 16 without increasing the number of parts and the number of assembly steps and increasing the size of the socket. In this state, it is possible to ensure the contact stability between the contact pin 15 and the IC package 12 by preventing the latch 16 from moving.

また、ラッチ１６は、閉状態で、操作部材１７から***作部１６ｃへの操作力が解除されると、開方向へ回動されるように、ラッチ１６の重心位置及びラッチ軸２４の位置が所定の位置関係に設定されているため、ストッパ壁１７ａを形成するだけの簡単な構造の改良で、ラッチ１６専用のばねを用いる必要なく、操作部材１７の上下動によりラッチ１６の開閉動作を行わせることができる。   In addition, when the latch 16 is in a closed state and the operating force from the operating member 17 to the operated portion 16c is released, the position of the center of gravity of the latch 16 and the position of the latch shaft 24 are adjusted so as to rotate in the opening direction. Since it is set in a predetermined positional relationship, the latch 16 can be opened and closed by the vertical movement of the operating member 17 without the need for using a spring dedicated to the latch 16 by simply improving the structure by simply forming the stopper wall 17a. Can be made.

なお、ラッチ１６の形状やコンタクトピン１５の形状等は、上記実施の形態に限定されるものでなく、他の形状でも良いと共に、ＩＣパッケージ１２も、ＱＦＮ(Quad Flat Non-Leaded Package)タイプに限らず、ＬＧＡ(Land Grid Array)タイプやＢＧＡ(Ball Grid Array)タイプ等、他のタイプのものでも良いことは勿論である。   Note that the shape of the latch 16 and the shape of the contact pin 15 are not limited to the above embodiment, and may be other shapes, and the IC package 12 is also of a QFN (Quad Flat Non-Leaded Package) type. Of course, other types such as LGA (Land Grid Array) type and BGA (Ball Grid Array) type may be used.
