Description

本発明は、ボードツーボード（BOARD TO BOARD）タイプのコネクタ装置を構成するコネクタ（リセコネクタとプラグコネクタ）の吸着カバー、及び吸着カバーを備えたコネクタ（リセコネクタとプラグコネクタ）に関する。 The present invention relates to a suction cover for connectors (reset connector and plug connector) constituting a board-to-board type connector device, and a connector (reset connector and plug connector) provided with a suction cover.

ボードツーボードタイプのコネクタ装置は、一対の基板（BOARD、ＦＰＣを含む）にそれぞれ、リセコネクタと、このリセコネクタと嵌合関係となるプラグコネクタとを固定してなっている。このコネクタ装置では、各コネクタ（リセコネクタとプラグコネクタ）を基板に実装するため、各コネクタに予め吸着カバーを装着しておき、これをマウンタで吸着して基板上に搬送し、各コンタクトを基板上の端子に半田付け（リフロー）している。 In the board-to-board type connector device, a pair of substrates (including BOARD and FPC) is fixed with a receptacle connector and a plug connector in a fitting relationship with the receptacle connector. In this connector device, in order to mount each connector (reset connector and plug connector) on a board, a suction cover is attached to each connector in advance, this is sucked by a mounter and conveyed onto the board, and each contact is placed on the board. Soldered (reflowed) to the upper terminal.

このような目的で使用される吸着カバーは従来、単にコネクタの所定の位置に弾性を有する係止片のみで被着されていた。
登録実用新案第３０２５３２３号公報 Conventionally, the suction cover used for such a purpose has been simply attached to the connector at a predetermined position only with a locking piece having elasticity.
Registered Utility Model No. 3025323

この種のコネクタ装置は、コンタクトの小型化と狭ピッチ化、全体の小型化と低背化が極限迄進行している。このため、コネクタに吸着カバーを装着する作業性が悪化している。また、小型であるため、正しい位置に装着することが非常に困難であった。さらに、装着後の振動や衝撃が加わった場合に吸着カバーがズレたり、特に回転方向の場合は外れ易かった。 In this type of connector device, contact miniaturization and narrow pitch, and overall miniaturization and low profile are progressing to the limit. For this reason, the workability of attaching the suction cover to the connector is deteriorated. Moreover, since it is small, it was very difficult to mount it at the correct position. Further, the suction cover is displaced when vibration or impact is applied after mounting, and it is easy to come off especially in the rotational direction.

本発明は、コネクタに対する装着作業性に優れるとともにズレ難い吸着カバー、あるいは装着容易でズレ難い吸着カバーを備えたコネクタを得ることを目的とする。
また本発明は、コネクタを基板に実装する際、吸着カバーによってコネクタの変形を防止できる装置を得ることを目的とする。 An object of the present invention is to obtain a suction cover that is excellent in mounting workability with respect to a connector and is difficult to shift, or a connector that has a suction cover that is easily mounted and difficult to shift.
It is another object of the present invention to provide a device that can prevent deformation of a connector by a suction cover when the connector is mounted on a substrate.

本発明は、矩形の底壁と、この底壁から立ち上げた左右側壁及び前後側壁と、これらの側壁の間に位置する凹部とを有するインシュレータ、及びこのインシュレータの上記左右側壁にそれぞれ列状に支持されたコンタクトを有するコネクタに結合される吸着カバーにおいて、インシュレータの左右側壁上に渡る吸着面部と、この吸着面部から上記左右側壁に沿って延びて該インシュレータに着脱自在に係止される係止脚と、上記吸着面部から上記左右側壁の間に延びて上記凹部底壁に臨む一対の内部腕とを有することを特徴としている。係止脚は、左右側壁の外面に沿う外面係止脚でも内面に沿う内面係止脚でもよい。 The present invention includes an insulator having a rectangular bottom wall, left and right side walls and front and rear side walls raised from the bottom wall, and a recess positioned between the side walls, and a row on each of the left and right side walls of the insulator. In a suction cover coupled to a connector having a supported contact, a suction surface portion that extends over the left and right side walls of the insulator, and a latch that extends from the suction surface portion along the left and right side walls and is detachably locked to the insulator. It has a leg and a pair of internal arms extending between the left and right side walls from the suction surface portion and facing the bottom wall of the recess. The locking leg may be an outer locking leg along the outer surface of the left and right side walls or an inner locking leg along the inner surface.

この吸着カバーの一対の内部腕は、インシュレータの前後側壁の内側に沿って該吸着カバーの前後方向の位置決めをすることが好ましい。また、同じ一対の内部腕によって、インシュレータの左右側壁の内側にも同時に沿って該吸着カバーの左右方向の位置決めをさせることもできる。 The pair of internal arms of the suction cover is preferably positioned in the front-rear direction of the suction cover along the inside of the front and rear side walls of the insulator. Further, the suction cover can also be positioned in the left-right direction along the inside of the left and right side walls of the insulator by the same pair of inner arms.

内部腕のインシュレータ凹部底壁との接触部は平面とすることが望ましい。 The contact portion of the inner arm with the bottom wall of the insulator recess is preferably a flat surface.

本発明の吸着カバーは、金属、合成樹脂材料のいずれから形成してもよいが、特に金属製のときには、吸着カバーの内部腕がインシュレータの凹部底壁に当接するとき、その吸着面部裏面は、インシュレータの左右側壁上端部に当接しないようにすることが望ましい。つまり、吸着カバーの挿入端を吸着カバーの内部腕がインシュレータの凹部底壁に当接する位置で規制する態様である。 The suction cover of the present invention may be formed from either a metal or a synthetic resin material, but when the inner arm of the suction cover is in contact with the bottom wall of the concave portion of the insulator, particularly when the suction cover is made of metal, It is desirable not to contact the upper end portions of the left and right side walls of the insulator. That is, this is a mode in which the insertion end of the suction cover is regulated at a position where the inner arm of the suction cover comes into contact with the bottom wall of the recess of the insulator.

あるいは、逆に、吸着カバーの吸着面部裏面は、インシュレータの左右側壁に当接し、このとき吸着カバーの内部腕とインシュレータの凹部底壁との間にはクリアランスが形成されるようにしてもよい。つまり、吸着カバーの挿入端を吸着カバーの吸着面部裏面とインシュレータの左右側壁の上端部とが当接する位置で規制する態様である。 Or conversely, the suction surface portion back surface of the suction cover may contact the left and right side walls of the insulator, and at this time, a clearance may be formed between the inner arm of the suction cover and the bottom wall of the recess of the insulator. That is, this is a mode in which the insertion end of the suction cover is regulated at a position where the rear surface of the suction surface portion of the suction cover and the upper end portions of the left and right side walls of the insulator abut.

本発明は、吸着カバーの態様だけでなく、吸着カバーを装着したコネクタにも及ぶ。 The present invention extends not only to the mode of the suction cover but also to a connector equipped with the suction cover.

本発明は、プラグコネクタ、リセ（リセプタクル）コネクタのいずれにも適用可能である。 The present invention can be applied to both plug connectors and receptacle (receptacle) connectors.

本発明によれば、吸着カバーのコネクタに対する装着作業性を高めることができる。また吸着カバーの内部腕によって、振動や衝撃等の外乱が加わったとしてもズレ難くすることができるとともにコネクタを基板に実装する際の該コネクタの変形を防止し、装着（半田付け）信頼性を高めることができる。 According to the present invention, the mounting workability of the suction cover to the connector can be improved. In addition, the internal arm of the suction cover makes it difficult to shift even when a disturbance such as vibration or shock is applied, and prevents the connector from being deformed when the connector is mounted on the board, thereby improving mounting (soldering) reliability. Can be increased.

図１ないし図６は、本発明をプラグコネクタに適用した第一の実施形態を示している。 1 to 6 show a first embodiment in which the present invention is applied to a plug connector.

プラグコネクタ１０は、合成樹脂材料（耐熱絶縁樹脂材料）からなるプラグインシュレータ１１と、このプラグインシュレータ１１に支持された金属（銅）製のプラグコンタクト１２とを有している。プラグインシュレータ１１は矩形の底壁１１ａと、この底壁１１ａの各辺から立ち上げた一対の互いに平行な長辺側の左右側壁（挿入壁）１１ｂと、一対の互いに平行な短辺側の前後側壁（挿入壁）１１ｃとを備えており、これらの側壁によって中心部に凹部１１ｄが形成されている。「前後左右」は説明の便宜上のものであり、特定の場所や方向を述べたものではない。 The plug connector 10 includes a plug insulator 11 made of a synthetic resin material (heat-resistant insulating resin material) and a metal (copper) plug contact 12 supported by the plug insulator 11. The plug insulator 11 includes a rectangular bottom wall 11a, a pair of parallel left and right side walls (insertion walls) 11b raised from each side of the bottom wall 11a, and a pair of parallel short side front and rear sides. A side wall (insertion wall) 11c is provided, and a concave portion 11d is formed at the center by these side walls. “Front / Right / Left / Right” is for convenience of explanation and does not describe a specific place or direction.

左右側壁１１ｂには、両壁の中心線に関して対称形状のプラグコンタクト１２が一定ピッチでインサート成形されている。各プラグコンタクト１２は、左右側壁１１ｂの外面と内面に沿う凸Ｕ字状導通部１２ａ（図５）と、この凸Ｕ字状導通部１２ａに左右側壁１１ｂの外面で連なる接続脚１２ｂとを有している。プラグインシュレータ１１には、プラグコンタクト１２とは別に、前後側壁１１ｃ部分に位置させてダミーコンタクト１３がインサート成形されている。ダミーコンタクト１３の半田付け脚１３ａは、プラグコンタクト１２の接続脚１２ｂと並んでいる。接続脚１２ｂと半田付け脚１３ａは、基板Ｂ（図３ないし図５）の端子及びダミー端子（図示せず）に半田付け（リフロー）される。 Plug contacts 12 having a symmetrical shape with respect to the center line of both walls are insert-molded at a constant pitch on the left and right side walls 11b. Each plug contact 12 has a convex U-shaped conductive portion 12a (FIG. 5) along the outer surface and inner surface of the left and right side walls 11b, and a connection leg 12b connected to the convex U-shaped conductive portion 12a on the outer surface of the left and right side walls 11b. is doing. In addition to the plug contacts 12, dummy contacts 13 are insert-molded in the plug insulator 11 so as to be positioned at the front and rear side walls 11 c. The soldering legs 13 a of the dummy contacts 13 are aligned with the connection legs 12 b of the plug contacts 12. The connection legs 12b and the soldering legs 13a are soldered (reflowed) to the terminals and dummy terminals (not shown) of the substrate B (FIGS. 3 to 5).

吸着カバー（プレート）２０は、以上のプラグコネクタ１０をチップマウンタにより基板Ｂ上に搬送し、接続脚１２ｂ（と半田付け脚１３ａ）を各端子（とダミー端子）に半田付けする際に使用する。吸着カバー２０は、図１及び図６に単体形状を示すように、前後左右の中心線に関し対称な形状をしており、プラグインシュレータ１１の凹部１１ｄを覆い（塞ぎ）左右側壁１１ｂ上に延びる吸着面部（平面部）２１と、この吸着面部２１から左右側壁１１ｂの外面に延びる４本の外面係止脚２２と、吸着面部２１から左右側壁１１ｂの内側（凹部１１ｄ）に延びて底壁１１ａに接触する（臨む）一対の内部腕２３Ｘとを有している。 The suction cover (plate) 20 is used when the above plug connector 10 is transported onto the substrate B by a chip mounter, and the connection leg 12b (and soldering leg 13a) is soldered to each terminal (and dummy terminal). . As shown in FIGS. 1 and 6, the suction cover 20 has a symmetrical shape with respect to the front, rear, left and right center lines, and covers (closes) the recess 11 d of the plug insulator 11 and extends on the left and right side walls 11 b. A surface portion (planar portion) 21, four outer surface locking legs 22 extending from the suction surface portion 21 to the outer surface of the left and right side walls 11b, and extending from the suction surface portion 21 to the inside (recessed portion 11d) of the left and right side walls 11b to the bottom wall 11a. It has a pair of internal arms 23X that come into contact (facing).

各外面係止脚２２は、吸着面部２１と同一平面にあって前後側壁１１ｃ側に延びる同一平面脚２２ａと、この同一平面脚２２ａの先端から外方に延びた後下方に延びる外面脚２２ｂと、この外面脚２２ｂの下端に内方に向けて曲折形成した係止フック２２ｃとを有している。プラグインシュレータ１１の左右側壁１１ｂには、この係止フック２２ｃを掛け止める係止凹部１１ｅが形成されている。 Each outer surface locking leg 22 is on the same plane as the suction surface portion 21 and extends toward the front and rear side walls 11c, and an outer surface leg 22b that extends outward from the tip of the same planar leg 22a and extends downward. The outer leg 22b has a locking hook 22c bent inward at the lower end thereof. The left and right side walls 11b of the plug insulator 11 are formed with locking recesses 11e that lock the locking hooks 22c.

一対の内部腕２３Ｘは、外面係止脚２２の対をなす同一平面脚２２ａの間に延びる同一平面部２３ｃと、この同一平面部２３ｃの先端部を下方へ曲折した下方曲折腕２３ｄと、この下方曲折腕２３ｄの下端部を内方にＬ字状に曲折した接触腕２３ｅとを備えている。接触腕２３ｅはプラグインシュレータ１１の底壁１１ａと接触するもので平面からなっている。また、この一対の内部腕２３の接触腕２３ｂの最大間隔ｄ（図３）は、プラグインシュレータ１１の前後側壁１１ｃの内寸Ｄ（同）より僅かに小さく、前後側壁１１ｃに沿う。また、この一対の内部腕２３Ｘの最大幅ｗ（図５）は、左右側壁１１ｂ（凸Ｕ字状導通部１２ａ）の内寸Ｗ（同）より僅かに小さい。 The pair of internal arms 23X includes the same flat surface portion 23c extending between the same flat surface legs 22a forming a pair of the outer surface locking legs 22, a lower bent arm 23d bent downward at the front end portion of the same flat surface portion 23c, A contact arm 23e that is bent in an L shape inward at the lower end of the downward bent arm 23d is provided. The contact arm 23e is in contact with the bottom wall 11a of the plug insulator 11 and has a flat surface. Further, the maximum distance d (FIG. 3) between the contact arms 23b of the pair of inner arms 23 is slightly smaller than the inner dimension D (the same) of the front and rear side walls 11c of the plug insulator 11, and is along the front and rear side walls 11c. Further, the maximum width w (FIG. 5) of the pair of inner arms 23X is slightly smaller than the inner dimension W (same as above) of the left and right side walls 11b (convex U-shaped conducting portion 12a).

上記構成の本吸着カバー２０は、基板Ｂにプラグコネクタ１０を実装（半田付け）する前に、図２ないし図５に示すように、該プラグコネクタ１０に装着する。すなわち、吸着カバー２０の一対の内部腕２３をプラグインシュレータ１１の凹部１１ｄ内に挿入すると、一対の内部腕２３が左右側壁１１ｂに沿ってプラグコネクタ１０と吸着カバー２０の左右方向の平面位置が定まり、一対の内部腕２３が前後側壁１１ｃに沿って前後方向の平面位置が定まり、プラグインシュレータ１１の係止凹部１１ｅと外面係止脚２２の平面位置が合致する。従ってそのまま挿入し続けると、やがて外面係止脚２２の係止フック２２ｃが係止凹部１１ｅに係合し、装着作業が終了する（図２）。この装着状態では、吸着カバー２０がプラグコネクタ１０に対して位置ズレを生じることがなく、特に回転方向に位置ズレが生じることがない。 The main suction cover 20 having the above configuration is attached to the plug connector 10 as shown in FIGS. 2 to 5 before the plug connector 10 is mounted (soldered) on the board B. That is, when the pair of inner arms 23 of the suction cover 20 is inserted into the recess 11d of the plug insulator 11, the pair of inner arms 23 determines the planar positions of the plug connector 10 and the suction cover 20 in the left-right direction along the left and right side walls 11b. The pair of inner arms 23 are positioned in the front-rear direction along the front-rear side wall 11c, and the engagement recess 11e of the plug insulator 11 and the planar position of the outer-surface engagement leg 22 match. Therefore, if the insertion is continued as it is, the locking hook 22c of the outer surface locking leg 22 will eventually be engaged with the locking recess 11e, and the mounting operation is completed (FIG. 2). In this mounted state, the suction cover 20 does not shift in position with respect to the plug connector 10, and in particular, does not shift in the rotational direction.

内部腕２３Ｘの高さ方向の有効長は、この装着終了状態において、吸着面部２１の裏面と左右側壁１１ｂの上端部との間に隙間Ｓ（図３）が生じるように定められており、吸着面部２１とプラグコンタクト１２の凸Ｕ字状導通部１２ａとが導通することがない。すなわち、吸着カバー２０の挿入端は、該吸着カバー２０の内部腕２３Ｘがインシュレータ１１の凹部底壁１１ａに当接する位置で規制されている。なお、隙間Ｓが極めて小さい場合や、吸着カバー２０の裏面とプラグコンタクト１２とを当接させる場合（すなわち、吸着カバー２０の挿入端を該吸着カバー２０の吸着面部２１とインシュレータ１１の左右側壁１１ｂの上端部と当接する位置で規制する場合）は、吸着カバー２０の裏面に樹脂コーティング等の絶縁体を形成して導通を防止することも可能である。 The effective length in the height direction of the inner arm 23X is determined so that a gap S (FIG. 3) is generated between the back surface of the suction surface portion 21 and the upper end portions of the left and right side walls 11b in this mounted end state. The surface portion 21 and the convex U-shaped conducting portion 12a of the plug contact 12 do not conduct. That is, the insertion end of the suction cover 20 is regulated at a position where the inner arm 23X of the suction cover 20 contacts the concave bottom wall 11a of the insulator 11. When the gap S is extremely small, or when the back surface of the suction cover 20 and the plug contact 12 are brought into contact (that is, the insertion end of the suction cover 20 is connected to the suction surface portion 21 of the suction cover 20 and the left and right side walls 11b of the insulator 11). In the case of regulation at a position where the upper end of the suction cover 20 abuts, it is possible to prevent conduction by forming an insulator such as a resin coating on the back surface of the suction cover 20.

チップマウンタは、図２の状態の吸着カバー２０の吸着面部２１を吸着し、基板Ｂ上の所定位置に搬送する。その搬送状態で、接続脚１２ｂ（と半田付け脚１３ａ）を各端子（とダミー端子）に半田付けし、終了後に吸着カバー２０をプラグコネクタ１０から離脱させる。吸着カバー２０を金属から構成した場合にも、吸着面部２１の裏面と凸Ｕ字状導通部１２ａとは非接触で導通がないことから、吸着カバー２０を装着した状態で電気的検査を実施したとしても問題は生じない。 The chip mounter sucks the suction surface portion 21 of the suction cover 20 in the state of FIG. 2 and conveys it to a predetermined position on the substrate B. In the transport state, the connection leg 12b (and the soldering leg 13a) is soldered to each terminal (and dummy terminal), and the suction cover 20 is detached from the plug connector 10 after completion. Even when the suction cover 20 is made of metal, the back surface of the suction surface portion 21 and the convex U-shaped conductive portion 12a are not in contact and do not conduct, so an electrical inspection was performed with the suction cover 20 mounted. However, no problem arises.

図７ないし図１２は、本発明をプラグコネクタに適用した第二の実施形態を示している。この実施形態は、主に吸着カバー２０の一対の内部腕２３の形状を第一の実施形態とは異ならせたものである。各内部腕２３は、一対の同一平面脚２２ａの間において下方へ曲折された下方曲折腕２３ａと、この下方曲折腕２３ａの下端部を外方にＵ字状に曲折した接触腕２３ｂとを有している。この接触腕２３ｂのプラグインシュレータ１１の底壁１１ａとの接触面２３ｂ’は平面である（図９）。この一対の内部腕２３の最大間隔ｄと最大幅ｗは、第一の実施形態と同様に、プラグインシュレータ１１の前後側壁１１ｃの内寸Ｄと左右側壁１１ｂの内寸Ｗより僅かに小さい。この他の構成要素は、実質的に第一の実施形態と同一であるので、共通の構成要素には同一の符号を付している。 7 to 12 show a second embodiment in which the present invention is applied to a plug connector. In this embodiment, the shape of the pair of internal arms 23 of the suction cover 20 is mainly different from that of the first embodiment. Each inner arm 23 has a lower bent arm 23a bent downward between a pair of identical planar legs 22a, and a contact arm 23b bent at the lower end of the lower bent arm 23a outwardly in a U-shape. is doing. The contact surface 23b 'of the contact arm 23b with the bottom wall 11a of the plug insulator 11 is a flat surface (FIG. 9). The maximum distance d and the maximum width w of the pair of inner arms 23 are slightly smaller than the inner dimension D of the front and rear side walls 11c of the plug insulator 11 and the inner dimension W of the left and right side walls 11b, as in the first embodiment. Since the other components are substantially the same as those of the first embodiment, common components are denoted by the same reference numerals.

この実施形態においても、図７に示す分離状態のプラグコネクタ１０と吸着カバー２０を図８のように装着し、この吸着カバー２０の吸着面部２１をチップマウンタで吸着して、第一の実施形態と同様の作用効果を得ることができる。 Also in this embodiment, the plug connector 10 and the suction cover 20 in the separated state shown in FIG. 7 are mounted as shown in FIG. 8, and the suction surface portion 21 of this suction cover 20 is sucked by the chip mounter. The same effect can be obtained.

図１３ないし図１９は、本発明をリセ（リセプタクル）コネクタに適用した第三の実施形態を示している。リセコネクタ３０は、第一の実施形態あるいは第二の実施形態のプラグコネクタと組み合わせて使用されるもので、合成樹脂材料（耐熱絶縁樹脂材料）からなるリセ（リセプタクル）インシュレータ３１と、このリセインシュレータ３１に支持された金属（銅）製のリセ（リセプタクル）コンタクト３２とを有している。リセインシュレータ３１は矩形の底壁３１ａと、この底壁３１ａの各辺から立ち上げた一対の互いに平行な長辺側の左右側壁３１ｂと、一対の互いに平行な短辺側の前後側壁３１ｃと、これら側壁の中心に位置する平面矩形の中央島部３１ｄとを備えており、これらの側壁と中央島部によって凹部３１ｅが形成されている。 FIGS. 13 to 19 show a third embodiment in which the present invention is applied to a receptacle connector. The receptacle connector 30 is used in combination with the plug connector of the first embodiment or the second embodiment. The receptacle connector 30 is made of a synthetic resin material (heat-resistant insulating resin material), and the receptacle insulator. And a metal (copper) recess (receptacle) contact 32 supported by 31. The re-insulator 31 includes a rectangular bottom wall 31a, a pair of left and right side walls 31b on the long side parallel to each other, and a pair of front and rear side walls 31c on the short side parallel to each other, raised from each side of the bottom wall 31a, The center island part 31d of the plane rectangle located in the center of these side walls is provided, and the recessed part 31e is formed of these side walls and the center island part.

リセインシュレータ３１の左右側壁３１ｂから底壁３１ａ及び中央島部３１ｄにかけては、左右側壁３１ｂの中心に関して対称形状のコンタクト収納溝３１ｆが一定ピッチで形成されており、各コンタクト収納溝３１ｆにそれぞれ、左右の側壁３１ｂで対称形状のリセコンタクト３２が収納されている。 From the left and right side walls 31b to the bottom wall 31a and the central island portion 31d of the re-insulator 31, contact storage grooves 31f that are symmetrical with respect to the center of the left and right side walls 31b are formed at a constant pitch. A symmetrical contact 32 is housed in the side wall 31b.

各リセコンタクト３２は、左右の側壁３１ｂで対称形状をしており、該側壁３１ｂの内外面に沿う逆Ｕ字状部３２ａと、側壁３１ｂの外側においてこの逆Ｕ字状部３２ａに連なる基板との接続脚３２ｂと、側壁３１ｂの内側において、逆Ｕ字状部３２ａに連なるＵ字溝状導通部３２ｃとを有している。接続脚３２ｂは、基板Ｂ２（図２）の端子（図示せず）に半田付けされる。このリセコネクタ３０では、第一、第二の実施形態のダミーコンタクト１３に代えて、固定金具３３が備えられ、この固定金具３３には、接続脚３２ｂに並ぶ半田付け脚３３ａが形成されている。 Each recess contact 32 has a symmetrical shape on the left and right side walls 31b, and an inverted U-shaped portion 32a along the inner and outer surfaces of the side wall 31b, and a substrate connected to the inverted U-shaped portion 32a outside the side wall 31b. Connecting leg 32b and a U-shaped groove-like conducting part 32c continuous with the inverted U-shaped part 32a inside the side wall 31b. The connection leg 32b is soldered to a terminal (not shown) of the substrate B2 (FIG. 2). The receptacle connector 30 is provided with a fixing bracket 33 in place of the dummy contact 13 of the first and second embodiments, and the fixing bracket 33 is formed with a soldering leg 33a aligned with the connection leg 32b. .

このリセコネクタ３０に装着される吸着カバー２０は、大きさを除き、実質的に第一の実施形態の吸着カバー２０と同一形状である。すなわち、吸着カバー２０は、リセインシュレータ３１の中央島部３１ｄ及び凹部３１ｅを覆い（塞ぎ）左右側壁３１ｂ上に延びる吸着面部（平面部）２１と、この吸着面部２１から左右側壁１１ｂの外面に延びる４本の外面係止脚２２と、吸着面部２１から左右側壁１１ｂの内側（凹部１１ｄ）に延びて底壁１１ａに接触する（臨む）一対の内部腕２３Ｘとを有している。外面係止脚２２は、第一、第二実施形態と同様であり、内部腕２３Ｘは第一の実施形態と同様である。一対の内部腕２３Ｘの最大間隔ｄと最大幅ｗは、リセインシュレータ３１の前後側壁３１ｃの内寸Ｄと左右側壁３１ｂの内寸Ｗより僅かに小さい。左右側壁３１ｂには、外面係止脚２２の係止フック２２ｃを掛け止める係止凹部３１ｇが形成されている。この他の構成要素は、実質的に第一の実施形態と同一であるので、共通の構成要素には同一の符号を付している。 The suction cover 20 attached to the receptacle connector 30 has substantially the same shape as the suction cover 20 of the first embodiment except for the size. That is, the suction cover 20 covers (closes) the central island portion 31d and the recess 31e of the reinsulator 31 and extends to the left and right side walls 31b, and extends from the suction surface portion 21 to the outer surface of the left and right side walls 11b. It has four outer surface locking legs 22 and a pair of inner arms 23X that extend from the suction surface portion 21 to the inside (recessed portion 11d) of the left and right side walls 11b and come into contact with (be faced) the bottom wall 11a. The outer surface locking leg 22 is the same as in the first and second embodiments, and the inner arm 23X is the same as in the first embodiment. The maximum distance d and the maximum width w of the pair of inner arms 23X are slightly smaller than the inner dimension D of the front and rear side walls 31c and the inner dimension W of the left and right side walls 31b. The left and right side walls 31b are formed with locking recesses 31g for locking the locking hooks 22c of the outer surface locking legs 22. Since the other components are substantially the same as those of the first embodiment, common components are denoted by the same reference numerals.

一方、この実施形態では、吸着カバー２０のリセコネクタ３０に対する挿入端は、吸着面部２１の裏面と左右側壁３１ｂの上端部とが接触する位置で規制され、この挿入端においては、内部腕２３Ｘと凹部底面３１ａとの間には、僅かなクリアランス（図１５）が生じる。これは、リセコンタクト３２の逆Ｕ字状部３２ａがコンタクト収納溝３１ｆ内に挿入されていて、左右側壁３１ｂの上端に露出していないからである。勿論、吸着カバー２０のリセコネクタ３０に対する挿入端を内部腕２３Ｘが凹部底面３１ａと当接する位置で規制することも可能である。 On the other hand, in this embodiment, the insertion end of the suction cover 20 with respect to the receptacle connector 30 is regulated at a position where the back surface of the suction surface portion 21 and the upper end portions of the left and right side walls 31b come into contact with each other. A slight clearance (FIG. 15) occurs between the bottom surface 31a of the recess. This is because the inverted U-shaped portion 32a of the recess contact 32 is inserted into the contact housing groove 31f and is not exposed at the upper ends of the left and right side walls 31b. Of course, it is also possible to restrict the insertion end of the suction cover 20 with respect to the receptacle connector 30 at a position where the inner arm 23X abuts the recess bottom surface 31a.

なお、第一または第二のプラグコネクタ１０の左右側壁１１ｂと前後側壁１１ｃは、このリセコネクタ３０の左右側壁３１ｂ、前後側壁３１ｃ及び中央島部３１ｄの隙間に挿入され、プラグコンタクト１２がリセコンタクト３２に導通する。 The left and right side walls 11b and the front and rear side walls 11c of the first or second plug connector 10 are inserted into the gaps between the left and right side walls 31b, the front and rear side walls 31c, and the central island portion 31d of the receptacle connector 30, and the plug contact 12 is the receptacle contact. Conducted to 32.

この実施形態でも、第一、第二の実施形態と同様に、リセコネクタ３０に吸着カバー２０を装着することができる。すなわち、吸着カバー２０の一対の内部腕２３Ｘをリセインシュレータ３１の凹部３１ｅ内に挿入すると、一対の内部腕２３Ｘが左右側壁３１ｂに沿ってリセコネクタ３０と吸着カバー２０の左右方向の平面位置が定まり、一対の内部腕２３Ｘが前後側壁３１ｃに沿って前後方向の平面位置が定まり、リセインシュレータ３１の係止凹部３１ｅと外面係止脚２２の平面位置が合致する。従ってそのまま挿入し続けると、やがて外面係止脚２２の係止フック２２ｃが係止凹部３１ｇに係合し、装着作業が終了する（図１４ないし図１８）。 Also in this embodiment, the suction cover 20 can be attached to the receptacle connector 30 as in the first and second embodiments. That is, when the pair of inner arms 23X of the suction cover 20 is inserted into the recess 31e of the recess insulator 31, the pair of inner arms 23X determines the horizontal plane positions of the receptacle connector 30 and the suction cover 20 along the left and right side walls 31b. The pair of inner arms 23X have a planar position in the front-rear direction along the front-rear side wall 31c, and the planar positions of the latching recess 31e of the recess insulator 31 and the outer-surface latching leg 22 match. Accordingly, if the insertion is continued as it is, the locking hook 22c of the outer surface locking leg 22 will eventually engage with the locking recess 31g, and the mounting operation is completed (FIGS. 14 to 18).

チップマウンタは、図１４の状態の吸着カバー２０の吸着面部２１を吸着し、基板Ｂ上の所定位置に搬送する。その搬送状態で、接続脚３２ｂ（と半田付け脚３３ａ）を各端子（とダミー端子）に半田付けし、終了後に吸着カバー２０をリセコネクタ３０から離脱させる。 The chip mounter sucks the suction surface portion 21 of the suction cover 20 in the state of FIG. 14 and conveys it to a predetermined position on the substrate B. In the transport state, the connection leg 32b (and the soldering leg 33a) is soldered to each terminal (and the dummy terminal), and the suction cover 20 is detached from the receptacle connector 30 after the end.

以上の各実施形態の吸着カバー２０は、基板Ｂにリフローする際のコネクタ１０、３０の変形を抑制する効果がある。図２０（Ａ）はリフロー時の変形を模式的に示している。常温時には実質的に平面形状を維持するコネクタ１０（３０）（インシュレータ１１（３１））は、リフロー時に２６０℃程度の温度が加わる。現在の合成樹脂製のコネクタ１０（３０）は低背小型であるため、この熱によって軟化して反りが生じ、常温に戻ってもその反りが残存してしまう。反りが生じる原因は、昇温によって内部応力が解放されるためではないかと考えられている。図２０（Ｂ）は、本発明の第三の実施形態を模式化して示したもので、吸着カバー２０の一対の内部腕２３Ｘがインシュレータ３１の凹部３１ｅに入り込んで凹部底壁３１ａに沿っているため、インシュレータ３１の変形を抑制することができる。第三の実施形態では、厳密には内部腕２３Ｘと凹部底壁３１ａとの間には僅かなクリアランスが存在するが、両者は、インシュレータ３１が変形を開始するとすぐに当接し、変形防止作用を発揮する。勿論、第一、第二の実施形態においても同様の作用効果を得ることができる。 The suction cover 20 of each of the above embodiments has an effect of suppressing deformation of the connectors 10 and 30 when reflowing to the substrate B. FIG. 20A schematically shows deformation during reflow. The connector 10 (30) (insulator 11 (31)) that maintains a substantially planar shape at room temperature is subjected to a temperature of about 260 ° C. during reflow. Since the present synthetic resin connector 10 (30) has a low profile and a small size, it is softened and warped by this heat, and the warp remains even when it returns to room temperature. It is thought that the cause of the warp is that internal stress is released by the temperature rise. FIG. 20B schematically shows the third embodiment of the present invention, in which the pair of inner arms 23X of the suction cover 20 enters the recess 31e of the insulator 31 and extends along the recess bottom wall 31a. Therefore, deformation of the insulator 31 can be suppressed. Strictly speaking, in the third embodiment, there is a slight clearance between the inner arm 23X and the recess bottom wall 31a. However, the two abut immediately after the insulator 31 starts to deform, and have a deformation preventing function. Demonstrate. Of course, the same effect can be obtained also in the first and second embodiments.
