[0002] 従来、電子部品と接触するコンタクトとして、例えばスプリング式コンタクトや、板バ ネコンタクトがある。スプリング式コンタクトは、電子部品と接触する接触部と、接触部 に対する押圧力に応じて伸縮するスプリング部とを備えている。ここで電子部品の一 例としては、信号の授受を行う電極を有するプリント基板やプローブカード、平面的 に IC端子が配列されている半導体デバイス(IC)がある。また、これら電子部品は、半 導体試験装置に使用される。例えばウェハプローバ装置や ICハンドラ装置等との間 で中継接続を行うデバイスインターフェース装置にも使用される。尚、必要とされるコ ンタタトのピン数は被試験デバイスの品種や同時測定する個数によって変わってくる が、例えば 2万ピン数以上が必要とされる場合がある。  [0002] Conventionally, as contacts that come into contact with electronic components, for example, there are a spring contact and a plate spring contact. The spring-type contact includes a contact portion that contacts the electronic component, and a spring portion that expands and contracts according to a pressing force on the contact portion. Here, examples of the electronic component include a printed circuit board and a probe card having electrodes for transmitting and receiving signals, and a semiconductor device (IC) in which IC terminals are arranged in a plane. These electronic components are used in semiconductor testing equipment. For example, it is also used as a device interface device for relay connection with a wafer prober device or IC handler device. The required number of contact pins varies depending on the type of device under test and the number of devices to be measured simultaneously. For example, more than 20,000 pins may be required.
[0003] また、板パネコンタクトは、弾性を有する板状のコンタクトであって、電子部品により 押圧された場合に、コンタクトの弾性により湾曲するコンタクトである。  [0003] The panel contact is a plate-shaped contact having elasticity, and is a contact that is bent by the elasticity of the contact when pressed by an electronic component.

When a large number of panel contacts are provided on the connector, the load and contact pressure per contact are small.
、接触不良を起こす問題がある。このため、低荷重、低接圧において、高い接続信頼 性を保つことのできる板パネコンタクトが望まれている。例えば、図 10に示す多数個 のコネクタ 100によりインターフェース部分では数万端子が必要となる場合がある。こ の場合、両者間の押圧力は大きな力が必要となる。また、両者間の押圧力に伴い、 両方の接続面において湾曲変形する難点がある。この為、コネクタ 100は可能な限り 低レ、押圧力であることが望まれてレ、る。 However, there is a problem of poor contact. For this reason, a panel contact that can maintain high connection reliability under low load and low contact pressure is desired. For example, as shown in Figure 10, Due to the connector 100, tens of thousands of terminals may be required at the interface. In this case, a large pressing force is required between the two. In addition, there is a problem that both connecting surfaces are curved and deformed due to the pressing force between them. For this reason, it is desirable that the connector 100 has as low a pressing force as possible.
[0006] また、多数の板パネコンタクトをコネクタに設けた場合、それぞれの板パネコンタクト が湾曲するため、それぞれの板パネコンタクト間の絶縁を良好に保つ必要がある。 課題を解決するための手段  [0006] Further, when a large number of board panel contacts are provided in the connector, each board panel contact is curved, so that it is necessary to maintain good insulation between the board panel contacts.

[0024] 波形整形部 412は、試験パターンを所定の波形に整形し、所定のタイミングにして 、テストヘッドで所定の振幅波形にした後、デバイスインターフェース装置 500を介し て単一又は複数のソケット 700に供給する。被試験デバイス 200はソケット 700に電 気的に接続された状態で、半導体試験装置 400との間で信号の授受を行う。判定部 414は、試験パターンに応じて被試験デバイス 200から出力される出力信号を、デバ イスインターフェース装置 500とテストヘッド 600を介して受け、前記期待値信号に基 づき所定のタイミングで比較が行われ、得られた比較結果に基づいて、被試験デバ イス 200の良否を判定する。  The waveform shaping unit 412 shapes the test pattern into a predetermined waveform, generates a predetermined amplitude at a predetermined timing, and forms a predetermined amplitude waveform with the test head. To supply. The device under test 200 transmits and receives signals to and from the semiconductor test apparatus 400 while being electrically connected to the socket 700. The determination unit 414 receives an output signal output from the device under test 200 according to the test pattern via the device interface device 500 and the test head 600, and performs comparison at a predetermined timing based on the expected value signal. Then, the quality of the device under test 200 is determined based on the obtained comparison result.
[0025] 図 10 (b)は、デバイスインターフェース装置 500の構成を示す図である。デバイスィ ンターフェース装置は、図 10 (b)の構成例に示すように、共通インターフェース部 51 0、複数のコネクタ 100、及び品種対応部 520を備える。共通インターフェース部 510 は、被試験デバイスの品種に依存しない部分であり、共通的に使用される。複数のコ ネクタ 100は、共通インターフェース部 510と品種対応部 520とが分離できるように着 脱可能なコネクタで電気的に接続する。品種対応部 520は、被試験デバイスの品種 に対応して交換される部分であり、その端部がソケット 700に接続されて、 ICハンドラ 装置に電気的 Z機械的に接続される。テストヘッドは、前記デバイスインターフェース 装置 500を電気的/機械的に接続して信号の授受、その他を行う。 尚、図 10 (a) に示すソケット 700は、ウェハプローバ装置の場合にはプローブカードのプローブ針 に該当する。  FIG. 10 (b) is a diagram showing a configuration of the device interface device 500. The device interface device includes a common interface section 510, a plurality of connectors 100, and a product type correspondence section 520 as shown in the configuration example of FIG. The common interface unit 510 is a part that does not depend on the type of the device under test and is commonly used. The plurality of connectors 100 are electrically connected by a detachable connector so that the common interface unit 510 and the product type corresponding unit 520 can be separated. The type corresponding unit 520 is a part that is exchanged according to the type of the device under test. The end is connected to the socket 700, and is electrically and mechanically connected to the IC handler device. The test head electrically / mechanically connects the device interface device 500 to exchange signals and perform other operations. The socket 700 shown in FIG. 10A corresponds to a probe needle of a probe card in the case of a wafer prober device.
[0026] ここで、共通インターフェース部 510と品種対応部 520との間で必要とされるピン数 は被試験デバイスの品種や同時測定する個数によつて変わってくるが、例えば 2万ピ ン数以上が必要とされる。従来では、 1ピン当たり 10グラム (約 0. 1ニュートン)の押圧 と仮定すると、 0. 1 X 20000 = 2000Nの押圧力で保持する必要があり、両者の接続 面の構造体は十分な強度の重量構造を備える必要性があり、実用上の難点がある。 尚、 ZIF (Zero insertion Force)型コネクタを適用する方法も考えられる力 電気的接 触/解放を行う機械的な駆動機構が必要となる為、高密度にピンを配列できない結 果、所望の多数ピンを実用的に実装できない。 Here, the number of pins required between the common interface unit 510 and the product type correspondence unit 520 varies depending on the product type of the device under test and the number of devices to be simultaneously measured. The above is required. Conventionally, 10 grams per pin (approximately 0.1 Newton) Assuming that, it is necessary to hold with a pressing force of 0.1 X 20000 = 2000N, and the structure of the connecting surface of both must have a weight structure with sufficient strength, which has practical difficulties. In addition, a method of applying a ZIF (Zero insertion Force) type connector is also conceivable. A mechanical drive mechanism that performs electrical contact / release is required, so that pins cannot be arranged at high density. The pins cannot be mounted practically.
[0027] 図 1は、本発明の実施形態に係るコネクタ 100の一例を示す図である。但し、後述 する多数個のコンタクト 60の表示は省略している。コネクタ 100は、例えば半導体デ バイスを試験する試験装置に使用されるものであり、半導体デバイスと半導体試験装 置 400との間で信号を受け渡しする。  FIG. 1 is a diagram showing an example of the connector 100 according to the embodiment of the present invention.

The upper substrate 12 is, for example, a substrate provided on the semiconductor device side, and the lower substrate 14 is, for example, a substrate provided on the test apparatus side. The relative positions of the upper substrate 12 and the lower substrate 14 are determined by the positioning holes 16. For example, the upper substrate 12 has a positioning hole 16 that penetrates the upper substrate 12, the lower substrate 14 has a projection that fits into the positioning hole 16, and the projection is fitted into the positioning hole 16. Thereby, the upper substrate 12 and the lower substrate 14 are fitted.
[0029] また、基板 10は、複数のコンタクトを基板 10の表面の縦方向及び横方向に予め定 められた間隔で配列するように保持する。また、基板 10は、スリット部 40の外形に対 応する貫通孔 26、 56 (図 3参照)が設けられる。また、当該貫通孔は、コンタクト保持 部を表出させる。また、基板 10は、試験装置側へ固定する構造として、例えば図 1に 示す 4個の取付孔を四隅に備える。コネクタ 100は、電気的に接続する一方の接続 相手に、当該取付孔によって取り付けられ固定される。  Further, the substrate 10 holds a plurality of contacts so as to be arranged at predetermined intervals in the vertical and horizontal directions on the surface of the substrate 10. Further, the substrate 10 is provided with through holes 26 and 56 (see FIG. 3) corresponding to the outer shape of the slit portion 40. In addition, the through hole exposes the contact holding portion. Further, the substrate 10 has, for example, four mounting holes shown in FIG. 1 at four corners as a structure to be fixed to the test apparatus side. The connector 100 is attached and fixed to one of the electrical connection partners through the attachment hole.
[0030] スリット部 40は、基板 10に設けられた複数のコンタクトを通過させるスリット 48が、同 一のピッチで簾状に複数設けられている。例えば、基板 10はコンタクト保持部によつ て複数のコンタクトを保持し、それぞれのコンタクトは、スリット 48を通過して電子部品 と接続する。また、基板 10は、複数のコンタクトを、スリット 48のピッチと略同一の間隔 で保持することが好ましい。 [0030] In the slit section 40, a plurality of slits 48 for allowing a plurality of contacts provided on the substrate 10 to pass therethrough are provided at the same pitch in a blind shape. For example, the substrate 10 holds a plurality of contacts by a contact holding portion, and each contact passes through the slit 48 and is Connect with Further, the substrate 10 preferably holds a plurality of contacts at substantially the same interval as the pitch of the slits 48.
[0031] 図 2は、コネクタ 100の断面の一例を示す図である。図 2においては、図 1に示した A-A'の断面を示す。前述したように、基板 10は、上側基板 12と下側基板 14との間 に設けられたコンタクト保持部 20を有する。コンタクト保持部 20は、複数のブロックに 分割されていてもよい。 FIG. 2 is a view showing an example of a cross section of the connector 100. FIG. 2 shows a cross section taken along the line AA ′ shown in FIG. As described above, the substrate 10 has the contact holding unit 20 provided between the upper substrate 12 and the lower substrate 14. The contact holding unit 20 may be divided into a plurality of blocks.
[0032] また、スリット部 40は、上側スリット部 42と下側スリット部 44とから構成される。上側 基板 12は、上側スリット部 42と略同一の形状の貫通孔を有し、上側スリット部 42を格 納し、下側基板 14は、下側スリット部 44と略同一形状の貫通孔を有し、下側スリット 部 44を格納する。また、コンタクト保持部 20は、上側スリット部 42と下側スリット部 44 との間に設けられる。例えば、下側スリット部 44のコンタクト保持部 20側の表面には、 コンタクト保持部 20と嵌合する複数の突起部 46が設けられる。またコンタクト保持部 2 0の下側スリット部 44側の表面には、下側スリット部 44と嵌合する複数の突起部 22が 設けられる。突起部 46と突起部 22とが嵌合することにより、コンタクト保持部 20は、下 側スリット部 44に対して所定の位置に配置される。  [0032] The slit portion 40 includes an upper slit portion 42 and a lower slit portion 44. The upper substrate 12 has a through hole having substantially the same shape as the upper slit portion 42, and stores the upper slit portion 42. The lower substrate 14 has a through hole having substantially the same shape as the lower slit portion 44. Then, store the lower slit part 44. Further, the contact holding section 20 is provided between the upper slit section 42 and the lower slit section 44. For example, on the surface of the lower slit portion 44 on the contact holding portion 20 side, a plurality of protrusions 46 that fit with the contact holding portion 20 are provided. A plurality of protrusions 22 that fit with the lower slits 44 are provided on the surface of the lower side of the contact holding parts 20 on the side of the lower slits 44. By fitting the protrusions 46 and the protrusions 22, the contact holding portion 20 is arranged at a predetermined position with respect to the lower slit portion 44.
[0033] また、コンタクト 60は、図 6において後述するように、コンタクト保持部 20に保持され る固定部と、固定部から電子部品側に延伸して設けられる保持部と、保持部から延 伸して設けられ、電子部品と接触する先端部とを有する。コンタクト 60の保持部は、 弾性材料により形成され、先端部が電子部品により押下された場合に、先端部を予 め定められた回動方向に回動させる。  As will be described later with reference to FIG. 6, the contact 60 includes a fixing portion held by the contact holding portion 20, a holding portion extending from the fixing portion to the electronic component side, and an extension extending from the holding portion. And a tip portion that comes into contact with the electronic component. The holding portion of the contact 60 is formed of an elastic material, and rotates the tip in a predetermined rotation direction when the tip is pressed by the electronic component.
[0034] また、コンタクト保持部 20は、複数のコンタクト 60を、回動方向を基板 10の表面に 投影した縦方向に、予め定められた間隔で配列させ、縦方向と垂直な横方向にスリツ ト 48のピッチと略同一の間隔で配列させるように保持する。つまり、複数のコンタクト 6 0は、縦方向及び横方向にそれぞれ予め定められたピッチで連続して設けられてお り、縦方向に一列に設けられたコンタクト 60は、同一のスリット 48を通過して電子部品 と接触する。  The contact holding unit 20 arranges the plurality of contacts 60 at predetermined intervals in the vertical direction in which the rotation direction is projected on the surface of the substrate 10, and slits the horizontal direction perpendicular to the vertical direction. G so that they are arranged at approximately the same pitch as the pitch of 48. That is, the plurality of contacts 60 are provided continuously at predetermined pitches in the vertical direction and the horizontal direction, respectively, and the contacts 60 provided in a line in the vertical direction pass through the same slit 48. Contacts with electronic components.
[0035] また、スリット部 40は、それぞれのスリット 48が縦方向に沿って設けられ、横方向に おいて隣接するコンタクト 60を、異なるスリット 48を通過させることにより離間させる。 このような構成により、コンタクト 60が電子部品によって押圧された場合であっても、 横方向において隣接するコンタクト 60がショートすることを防ぐことができる。また、ス リット 48力 コンタクト 60の回動方向を投影した縦方向に沿って設けられているため、 それぞれのコンタクト 60が電子部品の押圧に応じて回動することができ、コンタクト 60 が所定の接触圧で電子部品と接触することができる。また、スリット 48の基板 10の表 面と垂直な方向における深さは、コンタクト 60の保持部の基板 10の表面と垂直な方 向における高さと略同一であることが好ましい。つまり、スリット 48は、それぞれのコン タクト 60の保持部をほぼ覆う形状であり、横方向に隣接するコンタクト 60同士が接触 することを防ぐこと力 Sできる。 In the slit section 40, each slit 48 is provided along the vertical direction, and the adjacent contacts 60 in the horizontal direction are separated by passing through different slits 48. With such a configuration, even when the contact 60 is pressed by the electronic component, it is possible to prevent the adjacent contact 60 in the lateral direction from being short-circuited. Also, since the slit 48 force is provided along the vertical direction that projects the rotation direction of the contact 60, each contact 60 can rotate according to the pressing of the electronic component, and the contact 60 It can be in contact with electronic components with contact pressure. The depth of the slit 48 in the direction perpendicular to the surface of the substrate 10 is preferably substantially the same as the height of the holding portion of the contact 60 in the direction perpendicular to the surface of the substrate 10. In other words, the slit 48 has a shape substantially covering the holding portion of each contact 60, and can exert a force S for preventing the contacts 60 adjacent in the lateral direction from contacting each other.
[0036] また、下側基板 14は、上側基板 12と対向する面に、位置決め孔 16と嵌合する突 起部 18を有する。突起部 18が位置決め孔 16と嵌合することにより、下側基板 14に 対する上側基板 12の相対位置が定まる。また、図 2に示すように、上側スリット部 42 は、突起部 18が貫通する貫通孔を有していてもよい。突起部 18が当該貫通孔を貫 通することにより、下側基板 14に対する上側スリット部 42の相対位置が定まる。また、 下側基板 14は、下側スリット部 44と嵌合する突起部 24を更に有していてもよい。この 場合、下側スリット部 44は、突起部 24と嵌合する嵌合孔を有する。突起部 24が当該 嵌合孔と嵌合することにより、下側基板 14に対する下側スリット部 44の相対位置が定 まる。このような構成により、基板 10とスリット部 40との相対位置を定めることができる  The lower substrate 14 has a protrusion 18 on the surface facing the upper substrate 12 to be fitted in the positioning hole 16. The relative position of the upper substrate 12 with respect to the lower substrate 14 is determined by fitting the projection 18 into the positioning hole 16. Further, as shown in FIG. 2, the upper slit portion 42 may have a through hole through which the projection 18 penetrates. The relative position of the upper slit 42 with respect to the lower substrate 14 is determined by the projection 18 penetrating through the through hole. Further, the lower substrate 14 may further include a projection 24 that fits with the lower slit 44. In this case, the lower slit portion 44 has a fitting hole that fits with the protrusion 24. The relative position of the lower slit portion 44 with respect to the lower substrate 14 is determined by fitting the protrusion 24 into the fitting hole. With such a configuration, the relative position between the substrate 10 and the slit portion 40 can be determined.
[0037] 図 3は、コネクタ 100のそれぞれの構成部材の関係を説明する図である。但し、コン タクト保持部 20に備える多数のコンタクト 60は省略している。前述したように、上側基 板 12は、上側スリット部 42を格納するための貫通孔 26を有し、貫通孔 26に上側スリ ット部 42を格納する。また、上側スリット部 42は、下側基板 14の突起部 18が貫通す る貫通孔 50を有する。コンタクト保持部 20は、図 2に示すように下側スリット部 44に嵌 合して載置される。またコンタクト保持部 20は、図 5に示すように複数のブロックに分 割可能である。例えばコンタクト保持部 20は、コンタクト 60の一列又は複数列単位毎 に分割される。 FIG. 3 is a diagram illustrating the relationship between the respective constituent members of the connector 100. However, a number of contacts 60 provided in the contact holding unit 20 are omitted. As described above, the upper substrate 12 has the through-hole 26 for storing the upper slit portion 42, and stores the upper slit portion 42 in the through-hole 26. The upper slit 42 has a through hole 50 through which the projection 18 of the lower substrate 14 passes. As shown in FIG. 2, the contact holding section 20 is fitted and mounted on the lower slit section 44. Further, the contact holding section 20 can be divided into a plurality of blocks as shown in FIG. For example, the contact holding unit 20 is divided for each row of the contacts 60 or for each of a plurality of rows.
[0038] 下側スリット部 44には、コンタクトを試験装置側に通過させる複数のスリット 48、下 側基板 14と係合するための係合部 52、及び嵌合孔 82が設けられる。下側スリット部 44のスリット 48は、上側スリット部 42のスリット 48と対応する位置に設けられ、スリット 部 40を貫通する貫通孔を形成する。スリット 48はコンタクト 60が押圧により回動する ときに、コンタクト 60の長レヽ保持き 64、 66におレヽて、スリツ卜 48の両面に接角虫するよう にガイドされて回動することで図 6に示す先端部 68、 86が安定した位置関係を保つ こと力 Sできる。これにより、スリット 48の間隔を狭くすることができる結果、高密度にコン タクト 60を配設することが可能となる。 [0038] The lower slit portion 44 has a plurality of slits 48 through which the contact passes to the test apparatus side. An engagement portion 52 for engaging with the side substrate 14 and a fitting hole 82 are provided. The slit 48 of the lower slit portion 44 is provided at a position corresponding to the slit 48 of the upper slit portion 42, and forms a through-hole passing through the slit portion 40. When the contact 60 is rotated by pressing, the slit 48 is guided by the contact 60 so as to be in contact with the both sides of the slit 48 by rotating to the long rails 64, 66 of the contact 60, and is rotated. The force S can maintain the stable positional relationship between the tip portions 68 and 86 shown in FIG. As a result, the interval between the slits 48 can be reduced, so that it is possible to arrange the contacts 60 with high density.
[0039] また、下側基板 14は、下側スリット部 44を格納するための貫通孔 56を有し、貫通孔 56に下側スリット部 44を格納する。貫通孔 56には、下側基板 14の係合部 52と係合 する突起部 54が設けられる。突起部 54が係合部 52と係合し、突起部 24が嵌合孔 8 2と嵌合することにより、下側基板 14に対する下側スリット部 44の相対位置が定まる。  The lower substrate 14 has a through hole 56 for storing the lower slit portion 44, and stores the lower slit portion 44 in the through hole 56. The through hole 56 is provided with a projection 54 that engages with the engagement portion 52 of the lower substrate 14. The relative position of the lower slit portion 44 with respect to the lower substrate 14 is determined by the engagement of the projection 54 with the engagement portion 52 and the engagement of the projection 24 with the fitting hole 82.
[0040] つまり、上側基板 12と下側基板 14とは、上側スリット部 42と下側スリット部 44とを収容 して保持し、上側スリット部 42と下側スリット部 44とは、コンタクト保持部 20を上下方 向力 挟み込むように収容保持する。コンタクト保持部 20は、複数のコンタクト 60を 所定間隔に配設固定して備え、複数のコンタクト 60が上側スリット部 42と下側スリット 部 44のスリット 48に挿入されてスリット 48から露出すると共に、当該コンタクト 60がス リット 48により案内される。  That is, the upper substrate 12 and the lower substrate 14 receive and hold the upper slit portion 42 and the lower slit portion 44, respectively, and the upper slit portion 42 and the lower slit portion 44 20 is held and held so as to pinch it. The contact holding portion 20 includes a plurality of contacts 60 arranged and fixed at predetermined intervals, and the plurality of contacts 60 are inserted into the slits 48 of the upper slit portion 42 and the lower slit portion 44 and are exposed from the slits 48, The contact 60 is guided by the slit 48.
[0041] 図 4は、下側スリット部 44の拡大図の一例を示す。図 4においては、図 3に示した下 側スリット部 44の部分 Bを拡大した図を示す。下側スリット部 44は、コンタクト保持部 2 0のそれぞれのブロックのピッチと略同一のピッチで、縦方向に連続して設けられた 突起部 46を、コンタクト保持部 20と対向する面に有する。また突起部 46は、横方向 においても、スリット 48と同一のピッチで連続して設けられる。また、スリット 48は、横 方向に連続して設けられた突起部 46の間に設けられ、コンタクト 60を通過させる。  FIG. 4 shows an example of an enlarged view of the lower slit portion 44. FIG. 4 is an enlarged view of a portion B of the lower slit portion 44 shown in FIG. The lower slit portion 44 has, on the surface facing the contact holding portion 20, a projection 46 continuously provided in the vertical direction at substantially the same pitch as the pitch of each block of the contact holding portion 20. The projections 46 are also provided continuously at the same pitch as the slits 48 in the horizontal direction. The slits 48 are provided between the protrusions 46 provided continuously in the lateral direction, and allow the contacts 60 to pass therethrough.
[0042] 図 5は、複数のブロックに分割されたコンタクト保持部 20の一つのブロックを示す。  FIG. 5 shows one block of the contact holding unit 20 divided into a plurality of blocks.
コンタクト保持部 20の一つのブロックは、前述したように下側スリット部 44と嵌合する ための突起部 22を有する。突起部 22は、横方向に連続して設けられた複数の突起 部 46 (図 4参照)と嵌合する。本例においては、突起部 22が、縦方向に隣接する突 起部 46により形成される凹部に挿入される。 [0043] また、コンタクト保持部 20は、縦方向に連続して設けられた複数のブロックにより形 成される。複数のブロックは、縦方向に連続して設けられたそれぞれの突起部 46と嵌 合する。本例においては、コンタクト保持部 20のそれぞれのブロックの突起部 22が、 下側スリット部 44の突起部 46によって横方向に連続して形成される複数の凹部に揷 入される。これにより、コンタクト保持部 20のそれぞれのブロックは、下側スリット部 44 の所定の位置に載置される。 One block of the contact holding portion 20 has the protruding portion 22 for fitting with the lower slit portion 44 as described above. The protrusions 22 are fitted with a plurality of protrusions 46 (see FIG. 4) provided continuously in the lateral direction. In this example, the protrusion 22 is inserted into a recess formed by the protrusion 46 adjacent in the vertical direction. [0043] The contact holding unit 20 is formed by a plurality of blocks provided continuously in the vertical direction. The plurality of blocks are fitted with respective protrusions 46 provided continuously in the vertical direction. In the present example, the protrusions 22 of each block of the contact holding portion 20 are inserted into a plurality of recesses formed continuously in the lateral direction by the protrusions 46 of the lower slit portion 44. Thereby, each block of the contact holding section 20 is placed at a predetermined position of the lower slit section 44.
[0044] また、コンタクト保持部 20のそれぞれのブロックは、複数のスリット 48と対応する位 置に、複数のコンタクト 60を保持する。このような構成により、基板 10において連続し て設けられるべき複数のコンタクト 60を所定の位置に容易に保持することができる。  Each block of the contact holding unit 20 holds a plurality of contacts 60 at positions corresponding to the plurality of slits 48. With such a configuration, it is possible to easily hold a plurality of contacts 60 to be continuously provided on the substrate 10 at predetermined positions.
[0045] 図 6は、コンタクト 60の構成の一例を示す。コンタクト 60は導電材料による長尺の平 板部材で形成され、電子部品側先端部 68、電子部品側保持部 64、固定部 62、試 験装置側保持部 66、及び試験装置側先端部 86を有する。電子部品側先端部 68は 、基板 10の表面より電子部品に近い位置に設けられ、電子部品と接触する。尚、電 子部品がプリント基板の場合にはプリント基板のパターン電極に接触する。電子部品 側保持部 64は、電子部品側先端部 68から固定部 62まで延伸して設けられ、電子部 品により先端部 68が押下された場合に、電子部品側先端部 68を予め定められた回 動方向に回動させる。電子部品側保持部 64及び試験装置側保持部 66は、電子部 品の押下方向に対して斜めに設けられ、弾性材料により形成されることが好ましい。 また、電子部品側保持部 64は、上側スリット部 42のスリット 48を通過して設けられ、 試験装置側保持部 66は、下側スリット部 44のスリット 48を通過して設けられる。  FIG. 6 shows an example of the configuration of the contact 60. The contact 60 is formed of a long flat plate member made of a conductive material, and has an electronic component side tip 68, an electronic component side holding portion 64, a fixing portion 62, a test device side holding portion 66, and a test device side tip 86. Have. The electronic component side tip 68 is provided at a position closer to the electronic component than the surface of the substrate 10 and comes into contact with the electronic component. When the electronic component is a printed circuit board, it comes into contact with the pattern electrode of the printed circuit board. The electronic component side holding portion 64 is provided to extend from the electronic component side distal end portion 68 to the fixing portion 62, and when the electronic component presses the distal end portion 68, the electronic component side distal end portion 68 is determined in advance. Rotate in the direction of rotation. The electronic component side holding section 64 and the test apparatus side holding section 66 are preferably provided obliquely with respect to the pressing direction of the electronic component, and are preferably formed of an elastic material. Further, the electronic component side holding section 64 is provided through the slit 48 of the upper slit section 42, and the test apparatus side holding section 66 is provided through the slit 48 of the lower slit section 44.
[0046] 固定部 62は、コンタクト保持部 20により保持又は固定される。例えば、コンタクト保 持部 20は、コンタクト 60を保持するための貫通孔を有し、固定部 62は、当該貫通孔 により保持される。尚、コンタ外保持部 20が成形可能な樹脂部材の場合には、複数 個のコンタクト 60を一体成形で形成してもよレ、。固定部 62は、電子部品の押下方向 と平行に設けられることが好ましレ、。これにより複数のコンタクト 60がコンタクト保持部 20によって一列に位置決めされて整列保持された状態になる。これにより、スリット 4 8の間隔に対応した狭いピッチで整列することができるので、高密度にコンタクト 60を 配設することができる。 [0047] 試験装置側保持部 66は、固定部 62から試験装置側先端部 86まで延伸して設けら れる。また試験装置側先端部 86は、基板 10の裏面に対向する位置にある試験装置 側の電極面と接触する。また試験装置側先端部 86は、図 7—図 9において説明する 電子部品側先端部 68と同一の形状を有してよい。 The fixing part 62 is held or fixed by the contact holding part 20. For example, the contact holding section 20 has a through hole for holding the contact 60, and the fixing section 62 is held by the through hole. If the outer contour holding portion 20 is a moldable resin member, a plurality of contacts 60 may be formed by integral molding. The fixing portion 62 is preferably provided in parallel with the pressing direction of the electronic component. As a result, the plurality of contacts 60 are positioned in a line by the contact holding unit 20 and are aligned and held. Thus, the contacts 60 can be arranged at a narrow pitch corresponding to the interval between the slits 48, so that the contacts 60 can be arranged with high density. [0047] The test apparatus side holding section 66 is provided to extend from the fixed section 62 to the test apparatus side tip section 86. Further, the test device side tip 86 comes into contact with the test device side electrode surface at a position facing the back surface of the substrate 10. Further, the test apparatus side tip section 86 may have the same shape as the electronic component side tip section 68 described with reference to FIGS.
[0048] 図 7は、電子部品側先端部 68の一例を示す図である。図 7 (a)は、電子部品側先 端部 68の斜視図を示し、図 7 (b)は、延伸部 70の幅方向と垂直な面における電子部 品側先端部 68の断面図を示す。電子部品側先端部 68は、電子部品側保持部 64か ら延伸して設けられた延伸部 70と、延伸部 70の電子部品と略対向する対向面に、延 伸部 70の延伸方向と垂直な幅方向に沿って、延伸部 70の幅方向の一端力も他端 に渡って設けられる第 1の突起部 72とを有する。  FIG. 7 is a diagram illustrating an example of the electronic component-side distal end portion 68. FIG. 7A is a perspective view of the electronic component side front end portion 68, and FIG. 7B is a cross-sectional view of the electronic component side front end portion 68 on a plane perpendicular to the width direction of the extension portion 70. . The electronic component-side tip portion 68 extends perpendicularly to the extension direction of the extension portion 70 on an extension portion 70 provided by extending from the electronic component-side holding portion 64 and on a facing surface of the extension portion 70 substantially facing the electronic component. Along the wide width direction, the one end force in the width direction of the extending portion 70 also has a first projection 72 provided over the other end.
[0049] 図 7 (b)に示すように、第 1の突起部 72は、延伸部 70の幅方向と垂直な面における 断面の電子部品側の稜線が曲線であり、稜線の中央部が稜線の端部より電子部品 側に膨らんでいる。また、第 1の突起部 72は、延伸部 70より電子部品側に突起して おり、電子部品と接触する。第 1の突起部 72の稜線は、円の外周の一部を有してよく 、また楕円の外周の一部を有していてもよい。また、第 1の突起部 72の、延伸部 70の 幅方向と垂直な面における断面は、左右非対称であってもよい。  As shown in FIG. 7 (b), the first protrusion 72 has a curved ridge on the electronic component side in a cross section in a plane perpendicular to the width direction of the extension 70, and the center of the ridge is a ridge. Bulges toward the electronic component side from the end of the. Further, the first protrusion 72 protrudes toward the electronic component from the extension 70, and comes into contact with the electronic component. The ridge line of the first protrusion 72 may have a part of the outer circumference of a circle or may have a part of the outer circumference of an ellipse. Further, the cross section of the first protrusion 72 in a plane perpendicular to the width direction of the extension 70 may be asymmetrical in the left-right direction.
[0050] このような構成により、コンタクト 60は、第 1の突起部 72の曲面部分で電子部品と接 触する。このため、コンタクト 60と電子部品との接触面積を小さくでき、単位面積あた りの接触圧を大きくすることができるため、高い信頼性で電気的に接続することができ る。また、コンタクト 60と電子部品との接触圧が小さくした場合であっても、接触圧が 大きい場合と同等の接続信頼性を得ることができる。このため、多数のコンタクトを有 するコネクタと電子部品との接触圧を低減することができ、コネクタと電子部品とを容 易に着脱することができる。  With such a configuration, contact 60 makes contact with the electronic component at the curved surface of first projection 72. For this reason, the contact area between the contact 60 and the electronic component can be reduced, and the contact pressure per unit area can be increased, so that the electrical connection can be performed with high reliability. Even when the contact pressure between the contact 60 and the electronic component is reduced, the same connection reliability as when the contact pressure is large can be obtained. Therefore, the contact pressure between the connector having a large number of contacts and the electronic component can be reduced, and the connector and the electronic component can be easily attached and detached.
[0051] また、コンタクト 60と電子部品との接触面積を小さくすることにより、効果的にワイピ ングすることができる。このため、電子部品の電力に付着する酸化被膜等の異物を容 易に除去することができる。また、コンタクト 60と電子部品とが曲面で接触することに より、コンタクト 60が押下され電子部品側先端部 68が移動した場合に、第 1の突起部 72の異なる箇所で順次電子部品と接触する。このため、ワイビングにより異物を除去 するときに電子部品と接触する第 1の突起部 72の箇所を異ならせることができ、接続 の信頼性を向上させることができる。 [0051] Further, by reducing the contact area between the contact 60 and the electronic component, wiping can be performed effectively. Therefore, foreign matter such as an oxide film adhered to the electric power of the electronic component can be easily removed. In addition, when the contact 60 is pressed down and the electronic component side tip 68 moves due to the contact between the contact 60 and the electronic component on a curved surface, the electronic component contacts the electronic component sequentially at different locations of the first protrusion 72. . Therefore, foreign matter is removed by wiping In this case, the first protruding portions 72 that are in contact with the electronic component can be made different from each other, and the connection reliability can be improved.
[0052] 図 8は、電子部品側先端部 68の他の例を示す図である。図 8 (a)は、電子部品側 先端部 68の斜視図を示し、図 8 (b)は、延伸部 70の延伸方向と垂直な面における第 1の突起部 72の断面図を示す。図 7に関連して説明した例と同様に、電子部品側先 端部 68は、電子部品側保持部 64から延伸して設けられた延伸部 70と、延伸部 70の 電子部品と略対向する対向面に、延伸部 70の延伸方向と垂直な幅方向に沿って、 延伸部 70の幅方向の一端力 他端に渡って設けられる第 1の突起部 72とを有する。 また、第 1の突起部 72は、延伸部 70の幅方向と垂直な面における断面の電子部品 側の稜線が曲線であり、稜線の中央部が稜線の端部より電子部品側に膨らんでいる 。また、第 1の突起部 72は、延伸部 70より電子部品側に突起しており、電子部品と接 触する。 FIG. 8 is a view showing another example of the electronic component-side distal end portion 68. FIG. 8A is a perspective view of the electronic component-side tip portion 68, and FIG. 8B is a cross-sectional view of the first protrusion 72 in a plane perpendicular to the extending direction of the extending portion. As in the example described with reference to FIG. 7, the electronic component side leading end 68 is substantially opposed to the extended portion 70 provided by extending from the electronic component side holding portion 64 and the electronic component of the extended portion 70. On the opposing surface, a first protrusion 72 is provided along the width direction perpendicular to the extension direction of the extension portion 70 and provided at one end and the other end in the width direction of the extension portion 70. The first projection 72 has a curved ridge line on the electronic component side in a cross section in a plane perpendicular to the width direction of the extending portion 70, and a central portion of the ridge bulges toward the electronic component from an end of the ridge line. . In addition, the first protrusion 72 protrudes from the extension 70 toward the electronic component, and comes into contact with the electronic component.
[0053] 本例において、延伸部 70の延伸方向と垂直な面における、第 1の突起部 72の断 面の電子部品側の稜線は、図 8 (b)に示すように曲線であり、当該稜線の中央部が 当該稜線の端部より電子部品側に膨らんでいる。また同様に、延伸部 70の延伸方向 と垂直な面における、延伸部 70の断面の稜線も、中央部が当該稜線の端部より電子 部品側に膨らんでいてよい。このような構成により、コンタクト 60と電子部品側先端部 68との接触面積を更に低減することができる。また、第 1の突起部 72周辺の剛性を 高めること力 Sできる。  In the present example, the ridge line on the electronic component side of the cross section of the first projection 72 on the plane perpendicular to the direction of extension of the extension section 70 is a curve as shown in FIG. The center of the ridge bulges toward the electronic component from the end of the ridge. Similarly, the ridge line of the cross section of the extending portion 70 in a plane perpendicular to the extending direction of the extending portion 70 may have a central portion bulging toward the electronic component from an end of the ridge line. With such a configuration, the contact area between the contact 60 and the electronic component-side tip portion 68 can be further reduced. In addition, the force S for increasing the rigidity around the first projection 72 can be obtained.

On the opposing surface, there is a first protrusion 72 provided along the width direction perpendicular to the stretching direction of the stretching portion 70 and one end in the width direction of the stretching portion 70 and the other end.

[0058] 電子部品側先端部 68と電子部品とを接続する場合、例えばまず第 1の突起部 72 が電子部品と接触する。そして、電子部品が電子部品側先端部 68を押下することに より、電子部品側先端部 68は回動方向に回動する。このとき、第 1の突起部 72により 、電子部品の電極がワイビングされ異物を除去することができる。次に、第 2の突起部 74が電子部品と接触し、異物が除去された電極と電気的に接続する。このように、本 例の構成によれば、複数の突起部を設けることにより、ワイビングを行う機能を有する 突起部と、電子部品と電気的に接続する機能を有する突起部とを設けることができ、 接続の信頼性を更に向上させることができる。また、本例のように、複数の突起部を 連続して設けることにより、複数のコンタクト 60の角度にバラツキが生じた場合であつ ても、いずれかの突起部により上述したワイビングを行う機能を得ることができる結果 、接続の信頼性を更に向上させることができる。これにより、低接圧であっても良好な 電気的接触が得られる。 When connecting the electronic component side tip portion 68 and the electronic component, for example, first, the first protrusion 72 first contacts the electronic component.

[0059] 以上、本発明を実施の形態を用いて説明したが、本発明の技術的範囲は上記実 施の形態に記載の範囲には限定されない。上記実施の形態に、多様な変更または 改良をカ卩えることが可能であることが当業者に明らかである。その様な変更または改 良をカ卩えた形態も本発明の技術的範囲に含まれ得ることが、請求の範囲の記載から 明らかである。 As described above, the present invention has been described with reference to the embodiment. However, the technical scope of the present invention is not limited to the scope described in the above embodiment. It is apparent to those skilled in the art that various changes or improvements can be made to the above embodiment. It is apparent from the description of the appended claims that embodiments in which such changes or improvements are made can also be included in the technical scope of the present invention.
[0060] 例えば、図 6から図 9に示す電子部品側先端部 68の構造を試験装置側先端部 86 側に適用しても良い。前記の場合には上下両方の接触点において、接触圧が小さく ても効果的にワイビングすることができるため、接触圧が大きい場合と同等の接続信 頼性を得ることができ、上下両面に電子部品を接続することもできる。  For example, the structure of the tip 68 on the electronic component side shown in FIGS. 6 to 9 may be applied to the tip 86 on the test apparatus side. In the above case, wiping can be effectively performed at both upper and lower contact points even if the contact pressure is small, so that the same connection reliability as when the contact pressure is large can be obtained, and the electronic contact can be provided on both the upper and lower surfaces. Parts can also be connected.
[0061] また例えば、図 6に示す電子部品側先端部 68と電子部品側保持部 64との形状が上 下対称となるように形成しても良レ、。また例えば、図 5に示すコンタクト保持部 20のブ ロックはコンタクト 60を一列に配列するブロック単位の具体構造例で示した力 コンタ タト 60の複数列をブロック単位とした構成としても良い。  Further, for example, the shape of the electronic component side tip portion 68 and the electronic component side holding portion 64 shown in FIG. 6 may be formed so as to be vertically symmetrical. Further, for example, the block of the contact holding unit 20 shown in FIG. 5 may have a configuration in which a plurality of rows of the force contacts 60 shown in the specific structural example of the block unit in which the contacts 60 are arranged in a line are formed in the block unit.
[0062] また例えば、図 5に示すスリット部 44と嵌合する突起部 22を下側のみに備える具体 例で示したが、上下両方に備えて、図 3に示すコンタクト保持部 20が正転/反転の 何れでも実装可能にしても良レ、。また例えば、図 5に示すコンタクト 60の電子部品側 先端部 68の配設方向は全て同一方向へ配列する具体例で示したが、図 3に示す奇 数列のスリット 48に対応するコンタクト 60の配設方向と、偶数列のスリット 48に対応す るコンタクト 60の配設方向とを、逆方向に配設しても良レ、。この場合には、全コンタク トにおける半数が互いに反対方向に向いている結果、上下方向からの押圧力によつ て横方向への分力が相殺できる。特に、プローバ装置又は ICハンドラ装置と、前記 装置に接続される半導体試験装置のテストヘッドと、の間を中継接続するデバイスィ ンターフェース装置のように、多数個のコネクタ 100を使用する場合に有効である。 [0062] Further, for example, although the specific example in which the protruding portion 22 fitted with the slit portion 44 shown in Fig. 5 is provided only on the lower side is shown, the contact holding portion 20 shown in Fig. Even if it can be mounted in any of / reversal, it is OK. Also, for example, in the specific example in which the arrangement directions of the electronic component side tip portions 68 of the contacts 60 shown in FIG. 5 are all arranged in the same direction, the arrangement of the contacts 60 corresponding to the odd-numbered rows of slits 48 shown in FIG. The installation direction and the arrangement direction of the contacts 60 corresponding to the even-numbered rows of slits 48 may be reversed. In this case, as half of all contacts are in opposite directions, the lateral force can be offset by the vertical pressing force. In particular, a device for relay connection between a prober device or an IC handler device and a test head of a semiconductor test device connected to the device. This is effective when a large number of connectors 100 are used as in an interface device.
[0063] また例えば、図 1に示すスリット 48は横方向へ長く形成したスリット形状とした具体例 で示したが、縦方向へスリットを形成しても良レ、。このときは、縦方向のスリットに対応 するように、上側スリット部 42と下側スリット部 44とコンタクト保持部 20とを形成する。  Further, for example, although the slit 48 shown in FIG. 1 is a specific example in which the slit is formed to be long in the horizontal direction, the slit may be formed in the vertical direction. At this time, the upper slit part 42, the lower slit part 44, and the contact holding part 20 are formed so as to correspond to the vertical slit.
[0064] また例えば、図 10及び図 11に示すように、共通インターフェース部 510と品種対応 部 520との間で多数のコネクタ 100を配列する実施例がある。ここで、必要とされるコ ンタクト 60のピン数は被試験デバイスの品種や同時測定する個数によって変わって くる力 例えば 2万ピン数以上が必要とされる場合がある。本願のコンタクト 60におい て、 1ピン当たり 2グラム(糸勺 0. 02ニュートン)の甲圧と仮定すると、 0. 02 X 20000 = 400Nの押圧力で足りるので実用可能である。更に、本願のコネクタ 100は狭ピッチ で高密度に多数個のコンタクト 60を配設でき、且つ低荷重で高信頼性のある接続が 可能であるからして、機械的な構造も軽量化でき、より実用的な実装が可能である。  Further, for example, as shown in FIGS. 10 and 11, there is an embodiment in which a number of connectors 100 are arranged between the common interface unit 510 and the product type correspondence unit 520. Here, the required number of pins of the contact 60 depends on the kind of the device under test and the number to be simultaneously measured. Assuming a contact pressure of 2 grams per pin (0.02 Newtons) per pin at the contact 60 of the present application, a pressing force of 0.02 X 20000 = 400N is sufficient, so that it is practical. Further, the connector 100 of the present application can arrange a large number of contacts 60 at a high pitch with a narrow pitch, and can make a highly reliable connection with a low load. More practical implementation is possible.
