In addition, the socket S of the embodiment described later is an example of the socket of the present invention, and the present invention is not limited by the embodiment.

[實施型態] [Implementation Type]

參照圖1至圖5C，針對本實施型態的插座S加以說明。 1 to 5C, the socket S of this embodiment will be described.

如圖1及圖2所示，本實施型態是使用直角座標系統(X、Y、Z)來做說明。 As shown in Figure 1 and Figure 2, this embodiment uses a Cartesian coordinate system (X, Y, Z) for illustration.

直角座標系統(X、Y、Z)當中的X方向相當於插座S的橫方向。又，直角座標系統(X、Y、Z)當中的Y方向相當於插座S的縱方向。又，直角座標系統(X、Y、Z)當中的Z方向相當於插座S的高度方向。插座S的橫方向及插座S的縱方向亦可交換。 The X direction in the Cartesian coordinate system (X, Y, Z) is equivalent to the horizontal direction of the socket S. In addition, the Y direction in the Cartesian coordinate system (X, Y, Z) corresponds to the longitudinal direction of the socket S. In addition, the Z direction in the Cartesian coordinate system (X, Y, Z) corresponds to the height direction of the socket S. The horizontal direction of the socket S and the vertical direction of the socket S can also be exchanged.

又，直角座標系統(X、Y、Z)當中的Z方向也相當於插座S的上下方向。Z方向+側相當於插座S的上側，Z方向-側相當於插座S的下側。 In addition, the Z direction in the Cartesian coordinate system (X, Y, Z) is also equivalent to the vertical direction of the socket S. The Z direction + side corresponds to the upper side of the socket S, and the Z direction-side corresponds to the lower side of the socket S.

〈插座〉 <socket>

插座S是在檢查IC封裝80(參照圖5C)等電氣零件時，用來作為將IC封裝80與檢查用基板81(參照圖5C)電性連接的插座。本實施型態當中，IC封裝80屬於第一電氣零件之一例。又，檢查用基板81屬於第二電氣零件之一例。此外，也有檢查用基板81屬於第一電氣零件之一例，IC封裝80屬於第二電氣零件之一例的情況。 The socket S is used as a socket for electrically connecting the IC package 80 and the inspection substrate 81 (refer to FIG. 5C) when inspecting electrical components such as the IC package 80 (refer to FIG. 5C). In this embodiment, the IC package 80 is an example of the first electrical component. In addition, the inspection board 81 is an example of the second electrical component. In addition, there are cases where the inspection substrate 81 is an example of the first electrical component, and the IC package 80 is an example of the second electrical component.

複數個封裝側端子801(參照圖5C)呈矩陣狀設置在IC封裝80的下表面。封裝側端子801是例如銲錫球。又，複數個基板側端子811(參照圖5C)呈矩陣狀設置在檢查用基板81的上表面。 A plurality of package-side terminals 801 (refer to FIG. 5C) are arranged on the lower surface of the IC package 80 in a matrix. The package-side terminal 801 is, for example, a solder ball. In addition, a plurality of substrate-side terminals 811 (see FIG. 5C) are provided in a matrix on the upper surface of the inspection substrate 81.

以下的說明當中，將檢查中使用的插座S的狀態(圖4C及圖5C所示的狀態)稱為插座S的使用狀態。在插座S的使用狀態當中，插座S是以收容有IC封裝80的狀態配設在檢查用基板81上。在插座S的使用狀態當中，IC封裝80藉由覆蓋構件92等(參照圖2)的推壓構件朝向下方被推壓。此外，推壓構件可為構成插座S的一部分的構件，亦可與插座S為不同的裝置。 In the following description, the state of the socket S used in the inspection (the state shown in FIGS. 4C and 5C) is referred to as the use state of the socket S. In the use state of the socket S, the socket S is arranged on the inspection substrate 81 in a state in which the IC package 80 is accommodated. In the use state of the socket S, the IC package 80 is pressed downward by a pressing member such as the cover member 92 (refer to FIG. 2). In addition, the pressing member may be a member constituting a part of the socket S, or may be a device different from the socket S.

又，將未在插座S的下方配設檢查用基板81的狀態(圖4A及圖5A所示的狀態)稱為插座S的非配設狀態。又，將有在插座S的下方配設檢查用基板81的狀態(圖2、圖4B、及圖B所示的狀態)稱為插座S的配設狀態。插座S的配設狀態亦可視為插座S被載置於檢查用基板81上的狀態。此外，在圖2、圖4B、及圖5B所示的插座S的配設狀態當中，IC封裝80並未受到覆蓋構件92的推壓。 In addition, the state in which the inspection substrate 81 is not arranged under the socket S (the state shown in FIGS. 4A and 5A) is referred to as the non-disposed state of the socket S. In addition, the state in which the inspection substrate 81 is arranged below the socket S (the state shown in FIGS. 2, 4B, and B) is referred to as the arrangement state of the socket S. The arrangement state of the socket S can also be regarded as a state in which the socket S is placed on the inspection substrate 81. In addition, in the arrangement state of the socket S shown in FIGS. 2, 4B, and 5B, the IC package 80 is not pressed by the cover member 92.

首先，參照圖1至圖5C，針對本實施型態的插座S的概要加以說明。插座S具備：在使用時與第一電氣零件(IC封裝80)及第二電氣零件(檢查用基板81)接觸的觸針7、及插座主體1。觸針7被保持在插座主體1的保持部。 First, referring to FIGS. 1 to 5C, the outline of the socket S of this embodiment will be described. The socket S includes contact pins 7 that are in contact with the first electrical component (IC package 80) and the second electrical component (inspection substrate 81) during use, and the socket main body 1. The contact pin 7 is held by the holding portion of the socket main body 1.

插座主體1具有：在使用時被載置於檢查用基板81的固定部3；以及配置在固定部3的上方的可動部2。可動部2經由支撐部5彈性地被支撐在固定部3。支撐部5對於可動部2賦予上方的彈力。在插座S的配設狀態當中，可動部2可相對於固定部3在既定的衝程的範圍朝上下方向移動。 The socket main body 1 has a fixed part 3 mounted on the inspection substrate 81 during use, and a movable part 2 arranged above the fixed part 3. The movable part 2 is elastically supported by the fixed part 3 via the support part 5. The support part 5 imparts an upward elastic force to the movable part 2. In the arrangement state of the socket S, the movable portion 2 can move in the vertical direction relative to the fixed portion 3 within a predetermined stroke range.

再者，插座主體1具有引導位移部6。在插座S的非配設狀態當中，引導位移部6隨著自身朝向下方的移動而使可動部2朝向下方移動。在插座S的非配設狀態當中，引導位移部6可保持可動部2位於衝程的下端的狀態。 Furthermore, the socket main body 1 has a guide displacement part 6. In the non-arrangement state of the socket S, the guide displacement part 6 moves the movable part 2 downward as it moves downward. In the non-arranged state of the socket S, the guide displacement portion 6 can maintain the state in which the movable portion 2 is located at the lower end of the stroke.

另一方面，在插座S的配設狀態當中，引導位移部6基於從檢查用基板81承受的向上的力而朝向上方移動。接下來，當引導位移部6朝向上方移動時，可動部2與引導位移部6一起移動至衝程的上端。在該狀態當中，可動部2可相對於固定部3朝上下方向移動。 On the other hand, in the arrangement state of the socket S, the guide displacement portion 6 moves upward based on the upward force received from the inspection substrate 81. Next, when the guide displacement part 6 moves upward, the movable part 2 moves to the upper end of the stroke together with the guide displacement part 6. In this state, the movable portion 2 can move in the vertical direction relative to the fixed portion 3.

以下，針對插座S的具體構造加以說明。插座S具有插座主體1及複數個觸針7。此外，插座S亦可具有可收容插座主體1的殼構件91(參照圖2)。又，插座S亦可具有在插座S的使用狀態當中將IC封裝80朝向下方推壓的覆蓋構件92(參照圖2)。再者，插座S亦可具有在插座S的使用狀態當中將覆蓋構件92鎖固在殼構件91的鎖固機構(未圖示)。 Hereinafter, the specific structure of the socket S will be described. The socket S has a socket main body 1 and a plurality of contact pins 7. In addition, the socket S may have a shell member 91 (refer to FIG. 2) capable of accommodating the socket main body 1. In addition, the socket S may have a cover member 92 that pushes the IC package 80 downward during the use state of the socket S (see FIG. 2). Furthermore, the socket S may also have a locking mechanism (not shown) that locks the covering member 92 to the shell member 91 when the socket S is in use.

此外，殼構件91、覆蓋構件92、及鎖固機構可為構成插座S的一部分的構件，亦可與插座S為不同的裝置。 In addition, the shell member 91, the covering member 92, and the locking mechanism may be members constituting a part of the socket S, or may be different devices from the socket S.

殼構件91、覆蓋構件92、及鎖固機構的構造可為習知的各種構造。以下，針對插座主體1的構造加以說明。 The structure of the shell member 91, the covering member 92, and the locking mechanism may be various conventional structures. Hereinafter, the structure of the socket main body 1 will be described.

The placing portion 20 has a rectangular plate shape. The placement section 20 has a plurality of through holes 201 penetrating the placement section 20 in the up-down direction. The through hole 201 constitutes the movable side holding portion 28.

此外，本實施型態當中，可動部2當中形成有貫穿孔201的矩形區域(圖1當中以兩點鏈線α包圍的區域)相當於載置部20。 In addition, in the present embodiment, the rectangular area in which the through hole 201 is formed in the movable portion 2 (the area surrounded by the two-dot chain line α in FIG. 1) corresponds to the placing portion 20.

載置部20係以在上下方向與固定部3的間隔壁部31面對面的狀態配置在比間隔壁部31更上方處。當可動部2相對於固定部3朝上下方向移動時，載置部20的下表面與間隔壁部31的上表面的距離就改變。 The placing portion 20 is arranged above the partition wall portion 31 in a state of facing the partition wall portion 31 of the fixed portion 3 in the vertical direction. When the movable portion 2 moves in the vertical direction with respect to the fixed portion 3, the distance between the lower surface of the placing portion 20 and the upper surface of the partition wall portion 31 changes.

此外，固定側保持部34(保持孔311)的配置可依IC封裝80的封裝側端子801及檢查用基板81的基板側端子811的配置而適當決定。 In addition, the arrangement of the fixed-side holding portion 34 (holding hole 311) can be appropriately determined depending on the arrangement of the package-side terminals 801 of the IC package 80 and the substrate-side terminals 811 of the inspection substrate 81.

〈引導部〉 <Guide Department>

主引導部4一邊進行可動部2與固定部3的定位，一邊引導可動部2相對於固定部3之上下方向的移動。 The main guide part 4 guides the movement of the movable part 2 in the up-and-down direction relative to the fixed part 3 while positioning the movable part 2 and the fixed part 3.

主引導部4分別在插座S的第一區域、第二區域、第三區域、及第四區域之各者各設有兩個。 Two main guides 4 are provided in each of the first area, the second area, the third area, and the fourth area of the socket S, respectively.

以下，參照圖3，針對主引導部4的具體構造加以說明。主引導部4由主引導軸構件41A、可動部2的第二貫穿孔23a、23b、以及固定部3的第二貫穿孔34a、34b構成。 Hereinafter, referring to FIG. 3, the specific structure of the main guide 4 will be described. The main guide portion 4 is composed of a main guide shaft member 41A, the second through holes 23 a and 23 b of the movable portion 2, and the second through holes 34 a and 34 b of the fixed portion 3.

第二貫穿孔23a、23b及第二貫穿孔34a、34b的構造如以上所述。 The structures of the second through holes 23a, 23b and the second through holes 34a, 34b are as described above.

主引導軸構件41A從上起依序具有上側頭部411、小徑軸部413、段部412、大徑軸部414、及下側頭部415。 The main guide shaft member 41A has an upper head portion 411, a small diameter shaft portion 413, a step portion 412, a large diameter shaft portion 414, and a lower head portion 415 in this order from the top.

上側頭部411配置在可動部2的上側。上側頭部411的下表面抵接於可動部2的上表面。上側頭部411的下端部連接於小徑軸部413的上端部。 The upper head 411 is arranged on the upper side of the movable part 2. The lower surface of the upper head 411 abuts on the upper surface of the movable part 2. The lower end of the upper head 411 is connected to the upper end of the small-diameter shaft 413.

小徑軸部413插通在可動部2的第二貫穿孔23a、23b。小徑軸部413的外徑比第二貫穿孔23a、23b的內徑稍小。小徑軸部413的下端部連接於段部412。此外，雖省略圖示，但小徑軸部413具有可與大徑軸部414卡合(螺合)的螺絲部(公螺絲部或母螺絲部)。 The small-diameter shaft portion 413 is inserted through the second through holes 23 a and 23 b of the movable portion 2. The outer diameter of the small-diameter shaft portion 413 is slightly smaller than the inner diameter of the second through holes 23a and 23b. The lower end of the small-diameter shaft 413 is connected to the section 部412. In addition, although illustration is omitted, the small-diameter shaft portion 413 has a screw portion (a male screw portion or a female screw portion) that can be engaged (threaded) with the large-diameter shaft portion 414.

段部412是面向上方的圓環狀的平坦面。段部412將小徑軸部413與大徑軸部414連接。段部412抵接於可動部2的下表面。藉由上側頭部411及段部412，在上下方向夾住可動部2。藉由該構造，主引導軸構件41A被固定在可動部2。因此，主引導軸構件41A可與可動部2一起朝上下方向移動。 The segment 412 is an annular flat surface facing upward. The segment 412 connects the small-diameter shaft portion 413 and the large-diameter shaft portion 414. The step portion 412 abuts on the lower surface of the movable portion 2. The upper head portion 411 and the step portion 412 sandwich the movable portion 2 in the vertical direction. With this structure, the main guide shaft member 41A is fixed to the movable portion 2. Therefore, the main guide shaft member 41A can move in the vertical direction together with the movable portion 2.

大徑軸部414設在小徑軸部413的下側。大徑軸部414的外徑比小徑軸部413的外徑大。大徑軸部414插通在固定部3當中的第二貫穿孔34a、34b的斜面部341及第一小徑部342。 The large-diameter shaft portion 414 is provided on the lower side of the small-diameter shaft portion 413. The outer diameter of the large-diameter shaft portion 414 is larger than the outer diameter of the small-diameter shaft portion 413. The large-diameter shaft portion 414 is inserted through the inclined surface portion 341 and the first small-diameter portion 342 of the second through holes 34 a and 34 b in the fixed portion 3.

大徑軸部414的外徑比第二貫穿孔34a、34b的第一小徑部342的內徑稍小。藉由這種構造，大徑軸部414(主引導軸構件41A)的上下方向的移動由第二貫穿孔34a、34b的第一小徑部342引導。結果，可動部2能夠不傾斜地相對於固定部3朝上下方向移動。 The outer diameter of the large-diameter shaft portion 414 is slightly smaller than the inner diameter of the first small-diameter portion 342 of the second through holes 34a and 34b. With this structure, the vertical movement of the large-diameter shaft portion 414 (main guide shaft member 41A) is guided by the first small-diameter portion 342 of the second through holes 34a and 34b. As a result, the movable portion 2 can move in the vertical direction relative to the fixed portion 3 without tilting.

雖省略圖示，但大徑軸部414具有可與小徑軸部413的螺絲部413卡合(螺合)的螺絲部(母螺絲部或公螺絲部)。基於小徑軸部413的螺絲部與大徑軸部414的螺絲部的卡合(螺合)，上側頭部411與段部412在上下方向夾住可動部2。 Although illustration is omitted, the large-diameter shaft portion 414 has a screw portion (a female screw portion or a male screw portion) that can be engaged with (threaded) with the screw portion 413 of the small-diameter shaft portion 413. Due to the engagement (threading) between the screw portion of the small-diameter shaft portion 413 and the screw portion of the large-diameter shaft portion 414, the upper head portion 411 and the step portion 412 sandwich the movable portion 2 in the vertical direction.

下側頭部415連接於大徑軸部414的下端部。下側頭部415插入在固定部3當中的第二貫穿孔34a、34b的大徑部344。 The lower head 415 is connected to the lower end of the large-diameter shaft 414. The lower head 415 is inserted into the large diameter portion 344 of the second through holes 34 a and 34 b in the fixing portion 3.

下側頭部415的上表面在上下方向與第二貫穿孔34a、34b的第一段部343相對向。下側頭部415的上表面基於與第二貫穿孔34a、34b的第一段部343的卡合而將主引導軸構件41A朝向上方的移動限制在既定的範圍。 The upper surface of the lower head 415 faces the first section 343 of the second through holes 34a and 34b in the up-down direction. The upper surface of the lower head portion 415 restricts the upward movement of the main guide shaft member 41A to a predetermined range based on the engagement with the first step portion 343 of the second through holes 34a and 34b.

又，藉由下側頭部415的上表面與第一段部343的卡合，抑制主引導軸構件41A朝向上方脫出。 In addition, the engagement of the upper surface of the lower head portion 415 and the first stage portion 343 prevents the main guide shaft member 41A from coming out upward.

插座S的狀態從圖2及圖4B所示的插座S的配設狀態轉變成圖4A所示的非配設狀態時，主引導軸構件41A基於後述的引導位移部6的彈力而與可動部2一起朝向下方移動。 When the state of the socket S transitions from the arrangement state of the socket S shown in FIGS. 2 and 4B to the non-arrangement state shown in FIG. 4A, the main guide shaft member 41A interacts with the movable part based on the elastic force of the guide displacement part 6 described later 2 move downward together.

另一方面，插座S的狀態從插座S的非配設狀態轉變成配設狀態時，主引導軸構件41A與可動部2一起朝向上方移動。 On the other hand, when the state of the socket S changes from the non-arranged state of the socket S to the arranged state, the main guide shaft member 41A moves upward together with the movable portion 2.

〈支撐部〉〈Support section〉

支撐部5將可動部2彈性支撐在固定部3。這種支撐部5設在可動部2與固定部3之間。支撐部5對可動部2賦予向上的彈力。本實施型態的情況，支撐部5分別在插座S的第一區域、第二區域、第三區域、及第四區域之各者各設有三個。 The support part 5 elastically supports the movable part 2 to the fixed part 3. Such a supporting part 5 is provided between the movable part 2 and the fixed part 3. The support part 5 imparts upward elastic force to the movable part 2. In the case of this embodiment, three supporting portions 5 are provided in each of the first area, the second area, the third area, and the fourth area of the socket S, respectively.

以下，參照圖2至圖4C，針對支撐部5的具體構造加以說明。支撐部5具有引導軸構件51及彈性支撐部52。 Hereinafter, the specific structure of the support part 5 will be described with reference to FIGS. 2 to 4C. The support part 5 has a guide shaft member 51 and an elastic support part 52.

〈引導軸構件〉 <Guide shaft member>

引導軸構件51具有上側頭部511、軸部512、及下側頭部513。 The guide shaft member 51 has an upper head portion 511, a shaft portion 512, and a lower head portion 513.

上側頭部511屬於引導部的第一頭部之一例，其係配置在可動部2的上側。上側頭部511的下表面抵接於可動部2的上表面。上側頭部511的下端部連接於軸部512的上端部。 The upper head 511 is an example of the first head of the guide part, and is arranged on the upper side of the movable part 2. The lower surface of the upper head portion 511 abuts on the upper surface of the movable portion 2. The lower end of the upper head 511 is connected to the upper end of the shaft 512.

軸部512插通在可動部2的第一貫穿孔22a至22c及固定部3的第一貫穿孔33a至33c。軸部512的外徑比可動部2的第一貫穿孔22a至22c的內徑稍小。軸部512的下端部連接於下側頭部513。 The shaft portion 512 is inserted through the first through holes 22 a to 22 c of the movable portion 2 and the first through holes 33 a to 33 c of the fixed portion 3. The outer diameter of the shaft portion 512 is slightly smaller than the inner diameter of the first through holes 22 a to 22 c of the movable portion 2. The lower end of the shaft 512 is connected to the lower head 513.

下側頭部513屬於引導部的第二頭部之一例，其係連接於軸部512的下端部。下側頭部513配置在固定部3當中的第一貫穿孔33a至33c的大徑部333的下端部。大徑部333的下端部設在第四板部38。 The lower head portion 513 is an example of the second head portion of the guide portion, and is connected to the lower end portion of the shaft portion 512. The lower head 513 is arranged at the lower end of the large diameter portion 333 of the first through holes 33 a to 33 c in the fixing portion 3. The lower end of the large diameter portion 333 is provided on the fourth plate portion 38.

〈彈性支撐部〉〈Elastic support section〉

彈性支撐部52對可動部2賦予向上的彈力。在圖4B所示的插座S的配設狀態當中，彈性支撐部52以從固定部3浮起的狀態(稱為可動部2的浮動(floating)狀態)支撐可動部2。又，在插座S的配設狀態當中，彈性支撐部52以可相對於固定部3進行上下方向的移動的狀態支撐可動部2。 The elastic support portion 52 imparts upward elastic force to the movable portion 2. In the arrangement state of the socket S shown in FIG. 4B, the elastic support portion 52 supports the movable portion 2 in a state of floating from the fixed portion 3 (referred to as a floating state of the movable portion 2). In addition, in the arrangement state of the socket S, the elastic support portion 52 supports the movable portion 2 in a state in which it can move in the vertical direction with respect to the fixed portion 3.

彈性支撐部52具有本身為螺旋彈簧的第一彈簧521。第一彈簧521的外徑比引導軸構件51的上側頭部511的外徑小。藉由這種構造，彈性支撐部52的向上的彈力藉由上側頭部511被吸收。結果，彈性支撐部52的向上的彈力不會成為使可動部2撓曲的彎曲力矩而作用在可動部2。 The elastic support portion 52 has a first spring 521 which is a coil spring. The outer diameter of the first spring 521 is smaller than the outer diameter of the upper head 511 of the guide shaft member 51. With this structure, the upward elastic force of the elastic support portion 52 is absorbed by the upper head portion 511. As a result, the upward elastic force of the elastic support portion 52 does not act on the movable portion 2 as a bending moment that flexes the movable portion 2.

第一彈簧521設在可動部2的第一貫穿孔22a至22c及固定部3的第一貫穿孔33a至33c。第一彈簧521以包圍軸部512的方式設在引導軸構件51的軸部512的外徑側。 The first spring 521 is provided in the first through holes 22 a to 22 c of the movable portion 2 and the first through holes 33 a to 33 c of the fixed portion 3. The first spring 521 is provided on the outer diameter side of the shaft portion 512 of the guide shaft member 51 so as to surround the shaft portion 512.

第一彈簧521的上端部抵接於第一貫穿孔22a至22c的段部222。藉由第一彈簧521與引導軸構件51的上側頭部511在上下方向彈性地夾住可動部。藉由這種構造，支撐部5可與可動部2一起朝上下方向移動。 The upper end of the first spring 521 abuts against the segment 222 of the first through holes 22a-22c. The movable part is elastically sandwiched in the vertical direction by the first spring 521 and the upper head 511 of the guide shaft member 51. With this structure, the support part 5 can move in the vertical direction together with the movable part 2.

第一彈簧521向上推壓可動部2的力，係在插座S的狀態從非配設狀態(圖4A所示的狀態)轉變成配設狀態(圖4B所示的狀態)時可隨著引導軸構件51朝向上方的移動而使可動部2朝向上方移動的大小。 The force of the first spring 521 to push the movable portion 2 upwards can follow the guide when the state of the socket S changes from the non-arranged state (the state shown in FIG. 4A) to the arranged state (the state shown in FIG. 4B) The upward movement of the shaft member 51 causes the movable portion 2 to move upward.

第一彈簧521的下端部抵接於引導軸構件51的下側頭部513的上表面。第一彈簧521被壓縮在第一貫穿孔22a至22c的段部222與引導軸構件51的下側頭部513之間。第一貫穿孔22a至22c的段部222在上下方向與引導軸構件51的上側頭部511相對向，因此第一彈簧521亦可視為被壓縮在引導軸構件51的上側頭部511與下側頭部513之間。這種第一彈簧521的彈力並不直接施加在固定部3。 The lower end of the first spring 521 abuts on the upper surface of the lower head 513 of the guide shaft member 51. The first spring 521 is compressed between the segment 222 of the first through holes 22 a to 22 c and the lower head 513 of the guide shaft member 51. The segments 222 of the first through holes 22a to 22c are opposed to the upper head 511 of the guide shaft member 51 in the vertical direction, so the first spring 521 can also be regarded as being compressed on the upper head 511 and the lower side of the guide shaft member 51 Between the head 513. The elastic force of the first spring 521 is not directly applied to the fixing part 3.

〈引導位移部〉 <Guide displacement part>

在插座S的非配設狀態當中，引導位移部6隨著自身朝向下方的移動而使可動部2朝向下方移動。如圖2至圖4C所示，引導位移部6具有引導部61及位移部62等。 In the non-arrangement state of the socket S, the guide displacement part 6 moves the movable part 2 downward as it moves downward. As shown in FIGS. 2 to 4C, the guide displacement part 6 has a guide part 61, a displacement part 62, and the like.

〈引導部〉 <Guide Department>

引導部61屬於引導部之一例，其係一邊引導可動部2的上下方向的移動，一邊將位移部62的向下的彈力傳遞給可動部2者。引導部61由以上所述的引導軸構件51構成。引導軸構件51的構造如以上所述。 The guide part 61 is an example of a guide part, and it is one that transmits the downward elastic force of the displacement part 62 to the movable part 2 while guiding the movement of the movable part 2 in the vertical direction. The guide portion 61 is constituted by the guide shaft member 51 described above. The configuration of the guide shaft member 51 is as described above.

〈位移部〉 <Displacement part>

在插座S的非配設狀態當中，位移部62藉由使引導部61朝向下方移動而使可動部2朝向下方移動。 In the non-arrangement state of the socket S, the displacement portion 62 moves the movable portion 2 downward by moving the guide portion 61 downward.

位移部62具有第二彈簧621。第二彈簧621為螺旋彈簧。第二彈簧621設在固定部3的彈簧配置空間333a。 The displacement portion 62 has a second spring 621. The second spring 621 is a coil spring. The second spring 621 is provided in the spring arrangement space 333 a of the fixed portion 3.

第二彈簧621被設置成包圍引導軸構件51的軸部512及第一彈簧521。第二彈簧621的內徑比第一彈簧521的外徑大。 The second spring 621 is provided to surround the shaft portion 512 of the guide shaft member 51 and the first spring 521. The inner diameter of the second spring 621 is larger than the outer diameter of the first spring 521.

第二彈簧621的上端部抵接於固定部3當中的第一貫穿孔33a至33c的段部332。第二彈簧621的下端部抵接於引導軸構件51的下側頭部513的上表面。 The upper end of the second spring 621 abuts against the segment 332 of the first through holes 33 a to 33 c in the fixing portion 3. The lower end of the second spring 621 abuts on the upper surface of the lower head 513 of the guide shaft member 51.

如以上的第二彈簧621係對引導軸構件51賦予向下的彈力。 The second spring 621 as described above imparts a downward elastic force to the guide shaft member 51.

〈觸針〉〈Stylus〉

觸針7分別插通在固定側保持部34及可動側保持部28。 The contact pins 7 are inserted through the fixed-side holding portion 34 and the movable-side holding portion 28, respectively.

觸針7分別具有第一觸針要素71、第二觸針要素72、及彈性構件73。 The stylus 7 has a first stylus element 71, a second stylus element 72, and an elastic member 73, respectively.

第一觸針要素71是由具有導電性的材料構成的筒狀構件，在內徑側具有收容空間711。第一觸針要素71在內周面的中間部具有面向下方的圓環狀的支承部712。第一觸針要素71以可進行上下方向的移動的方式被保持在固定側保持部34。 The first stylus element 71 is a cylindrical member made of a conductive material, and has a housing space 711 on the inner diameter side. The first stylus element 71 has an annular support portion 712 facing downward in the middle portion of the inner peripheral surface.

彈性構件73的上端部抵接於第一觸針要素71的支承部712。彈性構件73的下端部抵接於第二觸針要素72的上端部。藉由這種構造，彈性構件73將第一觸針要素71與第二觸針要素72電性連接。 The upper end portion of the elastic member 73 abuts on the support portion 712 of the first contact pin element 71. The lower end of the elastic member 73 abuts on the upper end of the second contact pin element 72. With this structure, the elastic member 73 electrically connects the first contact pin element 71 and the second contact pin element 72.

第一觸針要素71及第二觸針要素72可依彈性構件73的收縮而彼此朝上下方向移動。 The first stylus element 71 and the second stylus element 72 can move in the vertical direction relative to each other in accordance with the contraction of the elastic member 73.

又，觸針7分別具有：在使用時(使用狀態)與IC封裝80的封裝側端子801接觸的上側接觸部713、以及在使用時與檢查用基板81的基板側端子811接觸的下側接觸部721。 In addition, the contact pins 7 each have an upper contact portion 713 that contacts the package-side terminal 801 of the IC package 80 during use (in use), and a lower contact portion that contacts the substrate-side terminal 811 of the inspection substrate 81 during use.部721.

上側接觸部713由第一觸針要素71的上端部構成。本實施型態的情況，不論插座S的狀態為何，上側接觸部713皆配置在可動部2的可動側保持部28的內側。此外，在插座S的使用狀態當中，上側接觸部713亦可從可動部2的可動側保持部28向上方突出。 The upper contact portion 713 is constituted by the upper end portion of the first contact pin element 71. In the case of this embodiment, regardless of the state of the socket S, the upper contact portion 713 is arranged inside the movable side holding portion 28 of the movable portion 2. In addition, in the use state of the socket S, the upper contact portion 713 may protrude upward from the movable side holding portion 28 of the movable portion 2.

〈針對插座的動作〉 <Action for socket>

以下，參照圖4A至圖5C，針對插座S的動作加以說明。 Hereinafter, the operation of the socket S will be described with reference to FIGS. 4A to 5C.

圖4A至圖4C顯示出設在圖2的Y2部分的支撐部5及引導位移部6的狀態。設在插座S當中的其他部分的支撐部5及引導位移部6的狀態與圖4A至圖4C所示的支撐部5及引導位移部6的狀態相同。 4A to 4C show the state of the supporting part 5 and the guiding displacement part 6 provided in the Y2 part of FIG. 2. The states of the support part 5 and the displacement guide part 6 provided in the other parts of the socket S are the same as the states of the support part 5 and the displacement guide part 6 shown in FIGS. 4A to 4C.

圖4A是插座S的非配設狀態當中相當於圖2的Y2部分的剖面圖。圖5A是非配設狀態當中的觸針7及觸針7周圍的剖面圖。 FIG. 4A is a cross-sectional view corresponding to the Y2 portion of FIG. 2 in the non-arranged state of the socket S. FIG. FIG. 5A is a cross-sectional view of the contact pin 7 and the vicinity of the contact pin 7 in a non-arranged state.

在插座S的非配設狀態當中，檢查用基板81並未配設在固定部3的下方。在插座S的非配設狀態當中，引導位移部6當中作為引導部61的引導軸構件51係基於引導位移部6當中的位移部62的第二彈簧621的向下的彈力而位於引導軸構件51的衝程的下端。 In the non-arranged state of the socket S, the inspection substrate 81 is not arranged under the fixed portion 3. In the non-arranged state of the socket S, the guide shaft member 51 as the guide portion 61 in the guide displacement portion 6 is positioned on the guide shaft member based on the downward elastic force of the second spring 621 of the displacement portion 62 in the guide displacement portion 6 The bottom end of the stroke of 51.

引導軸構件51的衝程的下端是圖4A所示的引導軸構件51的位置。引導軸構件51在衝程的下端當中，基於可動部2的下表面與固定部3(具體而言為第一板部35)的上表面的抵接而使得朝向下方的移動受到限制。 The lower end of the stroke of the guide shaft member 51 is the position of the guide shaft member 51 shown in FIG. 4A. At the lower end of the stroke, the guide shaft member 51 restricts its downward movement based on the contact between the lower surface of the movable portion 2 and the upper surface of the fixed portion 3 (specifically, the first plate portion 35).

在插座S的非配設狀態當中，引導軸構件51的下側頭部513比固定部3(具體而言為第四板部38)的下表面更向下方突出。 In the non-arrangement state of the socket S, the lower head 513 of the guide shaft member 51 protrudes downward from the lower surface of the fixed portion 3 (specifically, the fourth plate portion 38).

如圖5A所示，在插座S的非配設狀態當中，觸針7的下端部也比固定部3(具體而言為第四板部38)的下表面更向下方突出。又，在插座S的非配設狀態當中，觸針7的上端部(上側接觸部713)係配置在可動部2的可動側保持部28的內側。 As shown in FIG. 5A, in the non-arranged state of the socket S, the lower end portion of the contact pin 7 also protrudes downward from the lower surface of the fixed portion 3 (specifically, the fourth plate portion 38). Also, in the non-matching socket S In the set state, the upper end portion (upper contact portion 713) of the stylus 7 is arranged inside the movable side holding portion 28 of the movable portion 2.

此外，圖5A至圖5C中僅圖示出一個觸針7，而省略了其他的觸針7。圖5A至圖5C所示的觸針7以外的觸針7的狀態係與圖5A至圖5C所示的觸針7的狀態相同。 In addition, only one contact pin 7 is illustrated in FIGS. 5A to 5C, and the other contact pins 7 are omitted. The state of the contact pin 7 other than the contact pin 7 shown in FIGS. 5A to 5C is the same as the state of the contact pin 7 shown in FIGS. 5A to 5C.

在插座S的非配設狀態當中，可動部2係基於經由引導軸構件51傳遞的第二彈簧621的向下的彈力而位於圖4A所示的衝程的下端。 In the non-arranged state of the socket S, the movable portion 2 is located at the lower end of the stroke shown in FIG. 4A based on the downward elastic force of the second spring 621 transmitted via the guide shaft member 51.

在插座S的非配設狀態當中，可動部2(具體而言為載置部20及框部21)的下表面係抵接或接近固定部3(間隔壁部31及框部32)的上表面。本實施型態的情況，在插座S的非配設狀態當中，可動部2的下表面係抵接於固定部3的上表面。 In the non-arranged state of the socket S, the lower surface of the movable portion 2 (specifically, the mounting portion 20 and the frame portion 21) abuts or approaches the upper surface of the fixed portion 3 (partition wall portion 31 and frame portion 32) surface. In the case of this embodiment, in the non-arranged state of the socket S, the lower surface of the movable portion 2 abuts against the upper surface of the fixed portion 3.

然而，在插座S的非配設狀態當中，亦可在可動部2的下表面與固定部3的上表面之間存在有上下方向的間隙。該間隙的上下方向的尺寸較佳為比觸針7的上端部(上側接觸部713)的外徑小。該間隙的大小例如可藉由在可動部2、固定部3、及/或引導位移部6的構造下工夫而適當決定。 However, in the non-arranged state of the socket S, there may be a gap in the vertical direction between the lower surface of the movable portion 2 and the upper surface of the fixed portion 3. The size of the gap in the vertical direction is preferably smaller than the outer diameter of the upper end portion (upper contact portion 713) of the stylus 7. The size of the gap can be appropriately determined by, for example, making efforts in the structure of the movable portion 2, the fixed portion 3, and/or the guide displacement portion 6.

接下來，圖4B是插座S的配設狀態當中相當於圖2的Y2部分的剖面圖。圖5B是配設狀態當中的觸針7及觸針7周圍的剖面圖。 Next, FIG. 4B is a cross-sectional view corresponding to the Y2 portion of FIG. 2 in the arrangement state of the socket S. FIG. 5B is a cross-sectional view of the contact pin 7 and the vicinity of the contact pin 7 in the arranged state.

在插座S的配設狀態當中，檢查用基板81配設在固定部3的下方。然而，在圖4B所示的插座S的配設狀態當中，被放置在可動部2的載置部20的IC封裝80並未被覆蓋構件92(參照圖2)等的推壓構件朝向下方推壓。此外，檢查用基板81配設在固定部3的下方且IC封裝80未放置在載置部20的狀態也屬於插座S的配設狀態。 In the arrangement state of the socket S, the inspection substrate 81 is arranged below the fixing portion 3. However, in the arrangement state of the socket S shown in FIG. 4B, the IC package 80 placed on the placement portion 20 of the movable portion 2 is not pushed downward by a pressing member such as the cover member 92 (refer to FIG. 2). Pressure. In addition, the state in which the inspection substrate 81 is arranged below the fixing portion 3 and the IC package 80 is not placed on the mounting portion 20 also belongs to the arrangement state of the socket S.

在插座S的配設狀態當中，引導軸構件51位於衝程的上端。在插座S的配設狀態當中，第二彈簧621在固定部3當中的第一貫穿孔33a至33c的段部332與引導軸構件51的下側頭部513的上表面之間收縮。在插座S的配設狀態當中，第二彈簧621經常對引導軸構件51賦予向下的彈力。 In the arrangement state of the socket S, the guide shaft member 51 is located at the upper end of the stroke. In the arrangement state of the socket S, the second spring 621 contracts between the segment 332 of the first through holes 33 a to 33 c in the fixing portion 3 and the upper surface of the lower head portion 513 of the guide shaft member 51. In the arrangement state of the socket S, the second spring 621 always imparts a downward elastic force to the guide shaft member 51.

又，在插座S的配設狀態當中，觸針7比對應於插座S的非配設狀態的狀態更為收縮。其理由是因為，當插座S從非配設狀態轉變成配設狀態時，觸針7的下端部被配置在固定部3的下方的檢查用基板81朝向上方推壓。 Furthermore, in the arrangement state of the socket S, the contact pins 7 are more contracted than the state corresponding to the non-arrangement state of the socket S. The reason is that when the socket S changes from the non-arranged state to the arranged state, the lower end portion of the contact pin 7 is pushed upward by the inspection substrate 81 arranged below the fixed portion 3.

當插座S從非配設狀態轉變成配設狀態時，引導軸構件51被配置在固定部3的下方的檢查用基板81朝向上方推壓而朝向上方移動。如此一來，可動部2係與引導軸構件51一起移動至衝程的上端。其理由是因為，當引導軸構件51朝向上方移動時，可動部2被支撐部5當中的彈性支撐部52的第一彈簧521朝向上方推壓。 When the socket S transitions from the non-arranged state to the arranged state, the guide shaft member 51 is pushed upward by the inspection substrate 81 arranged below the fixed portion 3 and moved upward. In this way, the movable portion 2 moves together with the guide shaft member 51 to the upper end of the stroke. The reason is that when the guide shaft member 51 moves upward, the movable portion 2 is urged upward by the first spring 521 of the elastic support portion 52 among the support portions 5.

在插座S的配設狀態當中，可動部2可在既定的衝程的範圍相對於固定部3進行上下方向的移動。 In the arrangement state of the socket S, the movable part 2 can move up and down relative to the fixed part 3 within a predetermined stroke range.

在插座S的配設狀態當中，在可動部2的下表面與固定部3的上表面之間存在有上下方向的間隙。該間隙具有上下方向的既定長度。在插座S的配設狀態當中，觸針7的上端部(上側接觸部713)配置在可動部2的可動側保持部28的內側。 In the arrangement state of the socket S, there is a gap in the vertical direction between the lower surface of the movable portion 2 and the upper surface of the fixed portion 3. The gap has a predetermined length in the vertical direction. In the arrangement state of the socket S, the upper end portion (upper contact portion 713) of the contact pin 7 is arranged inside the movable side holding portion 28 of the movable portion 2.

接下來，圖4C是插座S的使用狀態當中相當於圖2的Y2部分的剖面圖。圖5C是使用狀態當中的觸針及觸針周圍的剖面圖。 Next, FIG. 4C is a cross-sectional view corresponding to part Y2 of FIG. 2 in the use state of the socket S. Fig. 5C is a cross-sectional view of the contact pin and the vicinity of the contact pin in use.

在插座S的使用狀態當中，被放置在可動部2的載置部20的IC封裝80係被覆蓋構件92等推壓構件朝向下方推壓。 In the use state of the socket S, the IC package 80 placed on the mounting portion 20 of the movable portion 2 is pressed downward by a pressing member such as the cover member 92.

在插座S的使用狀態當中，可動部2位於衝程的下端。在插座S的使用狀態當中，可動部2的下表面抵接於固定部3的上表面。插座S的使用狀態當中的引導軸構件51及觸針7的位置係與圖4B所示的插座S的配設狀態當中的引導軸構件51及觸針7的位置相同。 In the use state of the socket S, the movable part 2 is located at the lower end of the stroke. In the use state of the socket S, the lower surface of the movable part 2 abuts against the upper surface of the fixed part 3. The positions of the guide shaft member 51 and the contact pin 7 in the use state of the socket S are the same as the positions of the guide shaft member 51 and the contact pin 7 in the arrangement state of the socket S shown in FIG. 4B.

上述說明亦可適當沿用在設於插座S當中的其他部分的支撐部5及引導位移部6的動作的說明中。 The above description can also be appropriately used in the description of the actions of the support portion 5 and the guide displacement portion 6 provided in other parts of the socket S.

〈作用效果〉 <Effect>

根據如以上的本實施型態，在插座S的非配設狀態當中，可抑制觸針7的上端部(上側接觸部713)的損傷。 According to the present embodiment as described above, in the non-arranged state of the socket S, damage to the upper end portion (upper contact portion 713) of the contact pin 7 can be suppressed.

亦即，本實施型態的插座S的情況，在插座S的非配設狀態(圖4A所示的狀態)當中，可動部2(具體而言為載置部20)的下表面係抵接或接近固定部3(具體而言為間隔壁部31)的上表面。因此，在從觸針7朝向下方移動而使得觸針7的上端部從可動側保持部28朝向下方脫出的狀態使觸針7朝向上方移動時，觸針7的上端部不會進入可動部2(具體而言為載置部20)的下表面與固定部3的間隔壁部31的上表面之間。結果，可抑制觸針7的上端部的損傷。 That is, in the case of the socket S of this embodiment, in the non-arrangement state of the socket S (the state shown in FIG. 4A), the lower surface of the movable portion 2 (specifically, the mounting portion 20) is in contact with Or close to the upper surface of the fixed portion 3 (specifically, the partition wall portion 31). Therefore, when the contact pin 7 is moved upward in a state where the contact pin 7 is moved downward and the upper end portion of the contact pin 7 is released downward from the movable side holding portion 28, the upper end portion of the contact pin 7 does not enter the movable portion. 2 (specifically, the lower surface of the mounting portion 20) and the upper surface of the partition wall portion 31 of the fixing portion 3. As a result, damage to the upper end of the stylus 7 can be suppressed.

此外，在不僅成為觸針7的上端部脫出的狀態，而且連觸針7本身都從固定部3脫落的情況，就無法使觸針7輕易地復原。如此一來，便無法進行正常的檢查。在非配設狀態當中，本實施型態的插座S之可動部2的下表面係抵接或接近固定部3的上表面，因此亦可抑制觸針7的脫落。 In addition, in the case where not only the upper end portion of the contact pin 7 is detached, but also the contact pin 7 itself is detached from the fixed portion 3, the contact pin 7 cannot be easily restored. As a result, normal inspections cannot be performed. In the non-arranged state, the lower surface of the movable portion 2 of the socket S of this embodiment abuts or approaches the upper surface of the fixed portion 3, so the contact pin 7 can also be prevented from falling off.

又，根據本實施型態，還可抑制可動部2及固定部3的撓曲(彎曲)。亦即，本實施型態的情況，支撐部5的彈性支撐部52的向上的彈力係藉由設在可動部2的上側的引導軸構件51的上側頭部511被吸收。因此，彈性支撐部52的向上的彈力不會成為使可動部2撓曲的彎曲力矩而作用在可動部2。又，支撐部5的彈性支撐部52的向下的彈力係藉由引導軸構件51的下側頭部513被吸收。這種彈性支撐部52的向下的彈力不會成為使固定部3撓曲的彎曲力矩而作用在固定部3。基於以上理由，根據本實施型態，可抑制可動部2及固定部3的撓曲。 In addition, according to this embodiment, it is also possible to suppress the deflection (bending) of the movable portion 2 and the fixed portion 3. That is, in the case of this embodiment, the upward elastic force of the elastic support portion 52 of the support portion 5 is provided by The upper head portion 511 of the guide shaft member 51 on the upper side of the movable portion 2 is absorbed. Therefore, the upward elastic force of the elastic support portion 52 does not act on the movable portion 2 as a bending moment that flexes the movable portion 2. In addition, the downward elastic force of the elastic support portion 52 of the support portion 5 is absorbed by the lower head portion 513 of the guide shaft member 51. Such downward elastic force of the elastic support portion 52 does not act on the fixed portion 3 as a bending moment that flexes the fixed portion 3. For the above reasons, according to this embodiment, the deflection of the movable portion 2 and the fixed portion 3 can be suppressed.
