【産業上の利用分野】[Industrial applications]

本考案は、各種ICパッケージ等のICデバイスを搭載して該デバイスと外部 回路との接続を図るためのICソケットに関する。 The present invention relates to an IC socket for mounting an IC device such as various IC packages and connecting the device with an external circuit.

【従来の技術】[Prior Art]

近年のICデバイスの機能の拡張,高集積化に伴い、ICソケット自体におい ても、コンタクトピンの多ピン化やピン間隔及びピンの板厚の薄狭化が進んでい る。 With the recent expansion of functions and high integration of IC devices, even in the IC socket itself, the number of pins of the contact pins is increasing and the pin interval and the plate thickness of the pins are becoming thinner.

【0003】 図4及び図5は、例えばコンタクトピンの板厚が0.2〜0.4mm程度のも のを使用した、従来のICソケットの構成例を示しているが、図中、1はソケッ ト本体、2はソケット本体1に多数形成されたガイド壁1aに並設しつつ植設さ れていて該壁の底部に設けられた嵌挿孔1bに嵌挿された挿通端子2aとICデ バイスのリード端子と接触すべき接触端部2bを有しているコンタクトピン、3 はソケット本体1に棒軸4を介して回動可能に枢支される蓋体、5,5は蓋体3 に植設されていてソケット本体1に載置されたICデバイスをガイド・位置決め するための押圧パッド、6は蓋体3をソケット本体1に対して閉蓋状態に保持せ しめる係止レバーである。FIG. 4 and FIG. 5 show an example of the configuration of a conventional IC socket using, for example, a contact pin having a plate thickness of about 0.2 to 0.4 mm. The socket body 2 and the insertion terminal 2a, which are arranged in parallel with each other in the guide wall 1a formed in the socket body 1 and are inserted into the insertion hole 1b provided at the bottom of the wall, and the IC. A contact pin having a contact end portion 2b to be in contact with a lead terminal of the device, 3 is a lid body pivotally supported by the socket body 1 via a rod shaft 4, and 5 and 5 are lid bodies. 3 is a pressing pad for guiding and positioning the IC device placed in the socket body 1 mounted on the socket body 3, and 6 is a locking lever for holding the lid body 3 in the closed state with respect to the socket body 1. is there.

【0004】 かかる構成でなるICソケットにおいては、コンタクトピン2の板厚は0.2 〜0.4mm程度と厚く而も載置されるICデバイスのリード端子の数が比較的 多くないことから、ガイド壁1aの幅及び隣接する壁との間隔は十分広くとるこ とができ、ソケット本体1を合成樹脂を用いて射出成形により一体的に形成する ことは何ら問題がなかった。In the IC socket having such a configuration, the contact pin 2 has a large plate thickness of about 0.2 to 0.4 mm, and since the number of lead terminals of the IC device to be mounted is relatively small, The width of the guide wall 1a and the space between the guide wall 1a and the adjacent wall can be made wide enough, and there was no problem in integrally forming the socket body 1 by injection molding using a synthetic resin.

【考案が解決しようとする課題】[Problems to be solved by the device]

然し乍ら、前述したように、ICデバイスの機能の拡張,高集積化に伴って、 ICソケット自体もこれに対応させようとすると、ガイド壁1aの幅及び隣接す る壁との間隔はより薄狭化せざるをえず、ソケット本体1と極めて多数且つ微細 間隔で列設されるガイド壁1aとを一体的に形成しようとすると、溶融樹脂の流 動性から溶融樹脂が充填不足で形成される場合があった。即ち、合成樹脂を用い て射出成形する際に、成形用金型においてはゲート数が増えると共にゲート径を 大きくしなければならず又、金型温度,溶融樹脂温度及び該溶融樹脂の射出圧力 ,射出スピード等の成形条件を適正に設定・制御することが難しかった。又、多 ピン化に伴うガイド壁1aの壁間隔の薄狭化により、ガイド壁1aの強度は弱ま り、例えばコンタクトピン2が板厚が0.1〜0.15mm程度の極めて薄い部 材を用い而もピン間隔が0.3mm程度の微細間隔で多数植設される従来例の如 きICソケットでは、ICデバイスを載置して蓋体6を係止するとことにより押 圧パッド5,ICデバイス及びコンタクトピン2を介してガイド壁1aにかかる 押圧力は、コンタクトピン2の総本数が約80ピンの場合で3Kg・F,約20 0ピンの場合では8Kg・F程度の荷重にまで達し、該押圧力によりガイド壁1 aが破損し絶縁不良をおこしやすくなるという問題があった。そして、この問題 は前述したように、多ピン化やピン間隔及びピンの板厚の薄狭化が進む程、益々 大きな問題になった。 However, as described above, when the function of the IC device is expanded and the IC socket is made compatible with it, the width of the guide wall 1a and the space between the guide wall 1a and the adjacent wall are narrower. Inevitably, if an attempt is made to integrally form the socket body 1 and the guide walls 1a that are arranged in an extremely large number and at minute intervals, the molten resin will be insufficiently filled due to the fluidity of the molten resin. There were cases. That is, when injection molding is performed using a synthetic resin, the number of gates must be increased and the gate diameter must be increased in the molding die, and the mold temperature, the molten resin temperature and the injection pressure of the molten resin must be It was difficult to properly set and control molding conditions such as injection speed. Also, the strength of the guide wall 1a is weakened due to the thinning of the space between the guide walls 1a accompanying the increase in the number of pins, and for example, the contact pin 2 is a very thin member having a plate thickness of about 0.1 to 0.15 mm. In addition, in an IC socket such as the conventional example in which a large number of pins are implanted at a fine interval of about 0.3 mm, the IC pad is placed and the lid body 6 is locked so that the pressing pad 5, The pressing force applied to the guide wall 1a through the IC device and the contact pins 2 is 3 Kg · F when the total number of contact pins 2 is about 80 pins, and about 8 Kg · F when the number of contact pins 2 is about 200 pins. Then, there was a problem that the guide wall 1a was damaged by the pressing force and insulation failure was likely to occur. And, as mentioned above, this problem became more and more serious as the number of pins increased and the pin spacing and the plate thickness of the pins became thinner.

【0006】 本考案は、従来の技術の有するこのような問題点に鑑みてなされたものであり 、その目的とするところは、樹脂成形による製造を容易ならしめ、ピン間隔の薄 狭化等に有効に対応し得るようにしたICソケットを提供しようとするものであ る。The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to facilitate manufacturing by resin molding and to reduce the pin interval. It intends to provide an IC socket that can effectively deal with it.

And the fixing means is used to integrally fix the socket body and the guide carrier.

【実施例】【Example】

以下、図1乃至図3に基づき、本考案によるICソケットの一実施例を説明す る。図中、7は底部に突部7a,7b,7c,7d,7eとボス7f,7g,7 h,7iが形成されているソケット本体、8,8’は各2.0mm程度の厚さを 有し多数且つ微細間隔で列設されるガイド壁8a,8b,8c,8d,8e及び 8a’,8b’,8c’,8d’,8e’が夫々形成されているガイド担体であ り、該ガイド担体の四方にはソケット本体7のボス7f,7g,7h,7iと対 応した位置に穴8f,8g,8h,8i及び8f’,8g’,8h’,8i’が 夫々形成されている。ガイド担体8,8’のガイド壁8a,8b,8c,8d, 8e及び8a’,8b’,8c’,8d’,8e’の突部の裏側は凹部になって いて、ガイド壁8aと8a’,8bと8b’,8cと8c’,8dと8d’,8 eと8e’が夫々圧入して位置決め係合されソケット本体7の突部7a,7b, 7c,7d,7e上に夫々係合載置されるようになっている(図2参照)。そし て、ガイド担体8と8’の穴8fと8f’がソケット本体のボス7fに、穴8g と8g’がボス7gに、穴8hと8h’がボス7hに、穴8iと8i’がボス7 iに夫々嵌入し、ハトメ9によって一体的に固定される。尚、ハトメ9の管中に あけられた穴を介して、ICソケットをIC基板にネジによって固定することも 可能である。上記ガイド壁及び突部は係合位置決め手段を、又上記ボスとハトメ は固定手段を夫々構成している。 An embodiment of an IC socket according to the present invention will be described below with reference to FIGS. In the figure, 7 is a socket body having protrusions 7a, 7b, 7c, 7d, 7e and bosses 7f, 7g, 7h, 7i formed on the bottom, and 8 and 8'are each about 2.0 mm thick. A guide carrier having a plurality of guide walls 8a, 8b, 8c, 8d, 8e and 8a ', 8b', 8c ', 8d', 8e ', which are arranged in a row at fine intervals. Holes 8f, 8g, 8h, 8i and 8f ', 8g', 8h ', 8i' are formed on the four sides of the guide carrier at positions corresponding to the bosses 7f, 7g, 7h, 7i of the socket body 7, respectively. .. The guide walls 8a, 8b, 8c, 8d, 8e and 8a ', 8b', 8c ', 8d', 8e 'of the guide carriers 8, 8'are recessed on the back side of the projections, and the guide walls 8a and 8a ', 8b and 8b', 8c and 8c ', 8d and 8d', 8e and 8e 'are press-fitted and positioned and engaged, respectively, and engaged on the protrusions 7a, 7b, 7c, 7d, 7e of the socket body 7. It is designed to be mounted together (see Fig. 2). Then, the holes 8f and 8f ′ of the guide carriers 8 and 8 ′ are the boss 7f of the socket body, the holes 8g and 8g ′ are the boss 7g, the holes 8h and 8h ′ are the boss 7h, and the holes 8i and 8i ′ are the bosses. 7i are fitted in each and fixed integrally by eyelets 9. It is also possible to fix the IC socket to the IC board with a screw through a hole formed in the tube of the eyelet 9. The guide wall and the protrusion form an engagement positioning means, and the boss and the eyelet form a fixing means.

【0010】 又、コンタクトピン10は、例えば図3に示した形状のものを使用し、ソケッ ト本体7とガイド担体8,8’とを固定後、コンタクトピン10の基部10aの 両端をガイド担体8のガイド壁間に圧入し挿通端子10bをガイド壁の底部に設 けられた嵌挿孔(図示せず)に嵌挿して固定される。ICデバイスのリード端子 と接触すべき接触端部10cは別の仕切部材等(図示せず)でガイドされる。蓋 体は、図示されてないが、例えば図4及び図5に従来例として示した、押圧パッ ドを有するものを使用すれば良い。尚、ソケット本体7とガイド担体8,8’と の位置決め・嵌合は、上記したソケット本体7及びガイド担体8,8’に夫々形 成した凹凸部分で行わず、その他の部分に位置決め用の係合部を形成して行うよ うにしても良い。Further, the contact pin 10 has, for example, the shape shown in FIG. 3, and after fixing the socket body 7 and the guide carriers 8 and 8 ′, the both ends of the base portion 10 a of the contact pin 10 are connected to the guide carrier. 8 is press-fitted between the guide walls, and the insertion terminal 10b is fitted and fixed in a fitting insertion hole (not shown) provided at the bottom of the guide wall. The contact end 10c to be brought into contact with the lead terminal of the IC device is guided by another partition member or the like (not shown). Although the lid is not shown, for example, one having a pressing pad, which is shown as a conventional example in FIGS. 4 and 5, may be used. The positioning and fitting of the socket body 7 and the guide carriers 8 and 8 ′ are not performed at the uneven portions formed on the socket body 7 and the guide carriers 8 and 8 ′, respectively, but at other portions for positioning. It is also possible to form the engaging portion.

【0011】 本考案によるICソケットは上記のように構成されているから、その製造にお いて特にガイド担体8又は8’を射出成形する場合、ソケット本体7と別にガイ ド担体8又は8’が薄く形成されることにより、成形用金型のゲート径を小さく した上で、射出成形時における溶融樹脂の流動性を極めて良好にすることができ る。この結果、ガイド担体8,8’のガイド壁8a,8b,8c,8d,8e及 び8a’,8b’,8c’,8d’,8e’を微細間隔で多数形成する場合でも 、成形用金型に溶融樹脂を適正に充填することができ、金型温度,溶融樹脂温度 及び溶融樹脂の射出圧力,射出速度等の成形条件は容易且つ正確に設定・制御す ることができる。Since the IC socket according to the present invention is configured as described above, when the guide carrier 8 or 8 ′ is manufactured by injection molding, the guide carrier 8 or 8 ′ is provided separately from the socket main body 7. By making it thin, the gate diameter of the molding die can be made small and the fluidity of the molten resin during injection molding can be made extremely good. As a result, even when a large number of guide walls 8a, 8b, 8c, 8d, 8e and 8a ', 8b', 8c ', 8d', 8e 'of the guide carriers 8, 8'are formed at fine intervals, the molding metal is used. The mold can be properly filled with the molten resin, and the molding conditions such as the mold temperature, the molten resin temperature, the injection pressure of the molten resin, and the injection speed can be easily and accurately set and controlled.

【0012】 又、コンタクトピン10が多数植設される場合には、薄く形成されるガイド担 体8,8’を更に複数枚重ねて使用することにより、ICデバイスの装填時に蓋 体を係止することによりかかる押圧力に対して必要な強度が保証され得、ガイド 壁の破損は防止される。Further, when a large number of contact pins 10 are implanted, by using a plurality of thinly formed guide carriers 8 and 8 ′, the lid member is locked when the IC device is loaded. By doing so, the necessary strength can be ensured against such pressing forces and damage to the guide wall is prevented.

【考案の効果】[Effect of the device]

上述のように本考案によれば、ソケット本体とガイド担体を別々に形成したこ とにより、その樹脂形成を容易且つ適正に行うことができ、これによりコンタク トピンの多ピン化やピン間隔及びピンの板厚の薄狭化に有効に対応することがで きる。而も、ガイド担体を複数枚重ねて使用することによりガイド壁の強度は増 すので破損は生じ難く、従って絶縁不良はおこり難くなり、品質が向上する等の 利点がある。 As described above, according to the present invention, the socket body and the guide carrier are separately formed, so that the resin can be easily and properly formed, thereby increasing the number of contact pins, pin spacing, and pin spacing. It is possible to effectively cope with the thinning of the plate thickness. In addition, since the strength of the guide wall is increased by using a plurality of guide carriers in piles, damage is less likely to occur, and thus insulation failure is less likely to occur, which has the advantage of improving quality.
