3 2 5 8 2 5號公報所示的活 型連接器。該活動型連接器具備固定於配線基板的固定 體；及以可活動的狀態（浮動狀態）安裝於該固定殼體上 活動殼體。固定殼體如具有框體形狀，在該固定殼體内 動嵌裝著活動殼體。活動殼體係介由電連接用的複數連 器而安裝於固定殼體上，藉由連接器的彈性變形，允許 動殼體對固定殼體的變位，以吸收與應連接於該活動型 接器的對方側連接器的位置偏位。 在連接器上，在固定殼體側設有焊接於配線基板用的 線部。利用將該導線部焊接於配線基板上，以達成連接 312/發明說明書(補件)/93-03/92137436 對 器 連 的 對 偏 以 成 置 動 殼 的 游 接 活 連 導 器 5 1226728 與配線基板的電性連接。為防止應力集中於導線部，一般 設置將固定殼體固定於配線基板用的金屬扣環，而該金屬 扣環係焊接於配線基板上。 隨著電子機器等的小型化的趨勢，配線基板也逐漸小型 化。因此，要在小型配線基板上的有限面積的安裝面上安 裝多數的電氣、電子零件，連接器的小型化也不可或缺。 為達成活動型連接器的小型化，最好將固定殼體與活動 殼體的間隙盡可能減小。 但是，要減小兩殼體的間隙，固定殼體與活動殼體間的 接點的長度將變短，相應地，活動殼體的變位量減小，從 而有無法良好地吸收接點間的位置偏位的擔憂。 【發明内容】 本發明之目的在於，提供一種可確保活動殼體的足夠的 變位量，同時，可將連接器小型化的活動型連接器用接點 及使用其的活動型連接器。 本發明之活動型連接器用接點，係為安裝於具有固定於 配線基板的固定殼體π 〇 )、及可變位地結合該固定殼體的 活動殼體（2 0 )的活動型連接器的接點（3 0 )，其包含有：結 合於活動殼體的活動殼體側結合部（3 2 );結合於固定殼體 用的固定殼體側結合部（3 1 );連結上述活動殼體側結合部 與固定殼體側結合部的蛇行形狀的連結部（3 3 );設於上述 活動殼體側，與對方側連接器電性連接用的接點部（3 5 ); 及設於上述固定殼體側，焊接於配線基板用的導線部 (3 4 )。又，括號内的英文數字表示後述的實施形態的對應 6 3丨2/發明說明書(補件)/93-03/92丨37436 1226728 構成要素等，但這並不意味著本發明僅限於該實施形態的 解釋。以下，在該項中亦相同。 上述蛇行形狀的連結部最好為具有2個峰以上的蛇行形 狀。 本發明之活動型連接器，其包含有：固定於配線基板的 固定殼體；可對該固定殼體變位的活動殼體；及可變位地 將該活動殼體結合於上述固定殼體，同時電性連接對方側 連接器與上述配線基板間用的上述接點。 根據該構成，活動殼體侧結合部與固定殼體側結合部之 間係由蛇行形狀的連結部（最好為具有2個以上的峰部）所 結合，因此，即使減小活動殼體與固定殼體的間隙，仍可 充分加長連結部的長度。藉此，減小上述間隙以圖獲活動 型連接器的小型化，同時，可確保活動殼體的足夠的變位 量，因此可良好地吸收該活動型連接器與對方側連接器的 位置偏位。 又，若將蛇行形狀的連結部設為1個峰，為確保相當量 的彎曲量，必須要將峰的高度設為相當的高，使得連結部 從殼體大大突出，從而增大接觸部的露出量。在此，將蛇 行形狀的連結部設為2個峰，即使峰高不高仍可確保相當 量的彎曲量，連結部不會從殼體大大突出，接觸部的露出 量也減小。 本發明之上述目的或其他目的、特徵及效果，藉由參照 所附圖式而陳述如下的實施形態的說明，便可一目瞭然。 【實施方式】 3 12/發明說明書(補件)/93-03/92137436 1226728 圖1 ( a )為本發明之一實施形態的活動型連接器的俯視 圖，圖1(b)為其前視圖，圖1(c)為其仰視圖，圖1(d)為 其右側視圖。另外，圖2為上述活動型連接器的部分立體 圖，圖3 ( a )為顯示活動型連接器的使用狀態的側視圖，圖 3 ( b )為同樣顯示使用狀態的橫剖面圖。 圖1 ( a )表示在將該活動型連接器安裝於配線基板時，從 上往下看該配線基板的安裝面（安裝活動型連接器的面）的 俯視圖。在以下的說明中，將配線基板的安裝面側（圖1 ( b ) 的下側）作為下方進行說明。 又，圖中，活動型連接器的尺寸表示為較實際尺寸要 大，而該活動型連接器的實際尺寸為寬度6mm左右、長度 12 in hi左右、高度 3mni左右。 為了連接第1配線基板與第2配線基板的目的，該活動 型連接器1 0 0係藉由焊接而安裝於第1配線基板1的安裝 面1 a上。在第2配線基板2的安裝面2 a上，藉由焊接安 裝著對方側連接器5，藉由使該對方側連接器5與活動型 連接器1 0 0嵌合，以達成第1及第2配線基板1、2間的電 性連接。此時，活動型連接器1 0 0與對方側連接器5的位 置偏位，由活動型連接器1 0 0所吸收。 活動型連接器1 0 0具備：略長方形框狀的固定殼體1 0 ; 游動嵌合於該固定殼體1 0的長形狀的活動殼體2 0 ;呈架 橋狀設於固定殼體1 0與活動殼體2 0的電性連接用的複數 接點3 0 ;及設於固定殼體1 0的兩端的補強扣環4 0。 活動殼體2 0係設為相對固定殼體1 0確保指定的間隙的 8 3丨2/發明說明書(補件)/93-03/92137436 1226728 狀態，其在固定殼體1 0内，可在沿配線基板的安裝面的二 維方向上進行變位。也就是說，藉由接點30的彈性變形， 活動殼體2 0允許其對固定殼體1 0的相對變位。 固定殼體1 0係將沿活動殼體2 0的兩側的一對長邊部作 為連接固定部1 1。在該連接固定部1 1，以與該連接固定部 1 1交叉的姿勢相互平行且等間隔固定著複數的接點3 0。在 一對連接固定部1 1的端部分別形成結合補強扣環4 0的補 強扣環固定部1 3。在本實施形態中，一對連接固定部1 1 為分離式，以架橋結合該一對連接固定1 1的兩端部的方 式固定一對的補強扣環40。 在一對連接固定部1 1的兩端部間，在較補強扣環4 0的 下方，設有從活動殼體2 0的兩端面突出的止拔凸部2 6。 止拔凸部2 6在對方側連接器5脫落時，頂接於補強扣環 4 0的下部，以限制活動殼體2 0的移動。藉此，可防止施 加過大的外力於接點3 0。 圖4為沿著圖1 ( b)中的A -

The present invention relates to a movable connection having a floating structure and a contact point for a position deviation of an absorbable side connector. . [Prior Art] In an electronic device such as a digital camera, a plurality of wiring substrates are housed in a housing in a state where they are connected via a connector. When a pair of wiring boards are combined with two or more connectors, the position of the connectors may inevitably be shifted between one wiring board. In the state where the position is generated, each connector is subjected to stress. If it is used continuously, the connector's lead (soldering part) is peeled from the wiring, resulting in poor continuity. Here, in order to absorb the misalignment of the connectors between the wiring boards to be connected to each other, a flexible connector as shown in Japanese Patent Laid-Open No. 6-3 2 5 8 2 5 is used. The movable connector includes a fixed body fixed to a wiring substrate, and a movable case mounted on the fixed case in a movable state (floating state). If the fixed casing has the shape of a frame, a movable casing is fitted in the fixed casing. The movable casing is installed on the fixed casing through a plurality of connectors for electrical connection. The elastic deformation of the connector allows the movable casing to be displaced to the fixed casing to absorb and connect to the movable casing. The opposite side connector of the device is out of position. The connector is provided with a wire portion for soldering to a wiring board on the fixed housing side. The lead wire portion is soldered to the wiring substrate to achieve the connection 312 / Invention Manual (Supplement) / 93-03 / 92137436 The alignment of the coupler is connected to the movable connection guide 5 1226728 and the wiring. Electrical connection of the substrate. In order to prevent stress from being concentrated on the lead portion, a metal buckle for fixing the fixing case to the wiring board is generally provided, and the metal buckle is soldered to the wiring board. With the trend toward miniaturization of electronic devices and the like, wiring boards have also been miniaturized. Therefore, in order to mount a large number of electrical and electronic parts on a mounting surface with a small area on a small wiring board, the miniaturization of the connector is also indispensable. In order to achieve miniaturization of the movable connector, it is preferable to reduce the gap between the fixed case and the movable case as much as possible. However, to reduce the gap between the two shells, the length of the contact between the fixed shell and the movable shell will be shortened. Accordingly, the displacement of the movable shell will be reduced, so that the gap between the contacts cannot be absorbed well. Worries about the position deviation. SUMMARY OF THE INVENTION An object of the present invention is to provide a contact for a movable connector which can secure a sufficient displacement amount of a movable housing and can reduce the size of the connector, and a movable connector using the same. The contact for a movable connector of the present invention is a movable connector that is mounted on a fixed housing (π 0) having a fixed housing fixed to a wiring substrate and a movable housing (20) that is variably combined with the fixed housing. The contact (30) includes: a movable casing-side coupling portion (3 2) coupled to the movable casing; a fixed casing-side coupling portion (3 1) coupled to the fixed casing; and the above-mentioned activities A meander-shaped connecting portion (3 3) of the casing-side coupling portion and the fixed casing-side coupling portion; a contact portion (3 5) provided on the movable casing side and electrically connected to the connector on the counterpart side; and It is provided on the side of the fixed case, and is soldered to a lead portion (3 4) for a wiring board. In addition, the English numerals in parentheses indicate the correspondence of the embodiment described later 6 3 丨 2 / Invention Specification (Supplement) / 93-03 / 92 丨 37436 1226728, etc. However, this does not mean that the present invention is limited to this implementation only. Explanation of patterns. Hereinafter, the same applies to this item. It is preferable that the meandering connection portion has a meandering shape having two or more peaks. The movable connector of the present invention includes: a fixed casing fixed to a wiring substrate; a movable casing capable of displacing the fixed casing; and a movable casing combined with the fixed casing in a variable position At the same time, the above-mentioned contacts between the counterpart connector and the wiring substrate are electrically connected. According to this configuration, the movable casing-side coupling portion and the fixed casing-side coupling portion are connected by a meander-shaped coupling portion (preferably having two or more peak portions). Therefore, even if the movable casing and the The gap of the fixed casing can still sufficiently lengthen the length of the connecting portion. Thereby, the above-mentioned gap is reduced in order to obtain the miniaturization of the movable connector, and at the same time, a sufficient displacement amount of the movable housing can be ensured, so that the positional deviation between the movable connector and the counterpart connector can be well absorbed. Bit. In addition, if the meander-shaped connecting portion is set to one peak, in order to ensure a considerable amount of bending, the height of the peak must be set to be relatively high so that the connecting portion protrudes greatly from the housing, thereby increasing the contact portion. Exposed amount. Here, the meander-shaped connecting portion is set to two peaks, and even if the peak height is not high, a considerable amount of bending can be ensured, the connecting portion does not protrude greatly from the housing, and the exposed amount of the contact portion is reduced. The above and other objects, features, and effects of the present invention can be seen at a glance by stating the following description of embodiments with reference to the drawings.
