Abstract

<P>PROBLEM TO BE SOLVED: To take a large elevating length of a contact part without extending a total length of a surface-mounted contact. <P>SOLUTION: The surface-mounted contact 1 has a pair of hooking pieces 11 extended sideways from either side part of a flat-plate part 6 and a pair of locking pieces 13 erected at each side part of a jointing part 2 with a notch 15 for each hooking piece 11 to be inserted into. A position of the locking pieces 13 is at a side of the flat-plate part 6 and there is no need of arranging a structure for locking at a tip side the contact part 8, so that a total length of the surface-mounted contact 1 can be restrained by that much to extend an elevating length of the contact part as much. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、表面実装コンタクトの技術分野に属する。 The present invention belongs to the technical field of surface mount contacts.

プリント基板のアースパターン上に取り付けられて、そのプリント基板とシャーシ等の導電部材とを導通させるための表面実装コンタクトがある。
特開２００２−１７０６１５号公報（特許文献１）、特開２００２−１７０６１６号公報（特許文献２）には、導電性の金属板を曲げ加工して製造されており、下面が半田付けのための接合面とされる接合部、前記接合部の一端に連接された折返し部及び一端は前記折返し部に連接され他端は自由端とされて、該自由端側を前記接合部に接近、遠離させる方向に弾性変形可能な可動部であり、一部が接触導通のための接点部とされる可動部を備える表面実装コンタクトが開示されている。
特開２００２−１７０６１５号公報特開２００２−１７０６１６号公報 There is a surface mount contact mounted on the ground pattern of the printed circuit board for conducting the printed circuit board and a conductive member such as a chassis.

JP 2002-170615 A JP 2002-170616 A

従来の表面実装コンタクトは、特許文献１に開示されているように、接合部、折返し部及び可動部にて略Ｕ字状のばね構造を形成し、可動部が横方向に変形するのを防止するために接合部の先端部に一対の側壁部を立設し、また側壁部の上部を折り曲げて形成した係止部で可動部の先端部を係止することで、略Ｕ字状のばね構造が広げ変形させられるのを防止していた。このため、接点部は係止部よりも上方に突出している必要があり、可動部の略中央部に逆Ｕ字状などの凸部を設けて、これを接点部としていた。 As disclosed in Patent Document 1, the conventional surface mount contact forms a substantially U-shaped spring structure at the joint portion, the folded portion, and the movable portion, and prevents the movable portion from being deformed in the lateral direction. In order to achieve this, a pair of side wall portions are erected at the front end portion of the joint portion, and the front end portion of the movable portion is locked by a locking portion formed by bending the upper portion of the side wall portion. The structure was prevented from being expanded and deformed. For this reason, the contact portion needs to protrude above the locking portion, and a convex portion such as an inverted U-shape is provided at a substantially central portion of the movable portion, which is used as the contact portion.

このように可動部の略中央部に凸部が存在するために、可動部の上面を自動実装機のノズル吸着面として使用するのは難しかった。
なお、特許文献２のように、可動部を長くして、接点部となる凸部の位置を偏らせれば、可動部の上面をノズル吸着面として使用することもできるが、表面実装コンタクトの全長が長くなるという問題がある。 As described above, since the convex portion exists at the substantially central portion of the movable portion, it is difficult to use the upper surface of the movable portion as the nozzle suction surface of the automatic mounting machine.
In addition, if the movable part is lengthened and the position of the convex part serving as the contact part is biased as in Patent Document 2, the upper surface of the movable part can be used as a nozzle suction surface. There is a problem that becomes longer.

請求項１記載の表面実装コンタクトは、
下面が半田付けのための接合面とされる接合部と、前記接合部の一端に連接された折返し部と、一端は前記折返し部に連接され他端は自由端とされて、該自由端側を前記接合部に接近、遠離させる方向に弾性変形可能な可動部であり、一部が接触導通のための接点部とされる可動部とを備える表面実装コンタクトにおいて、
前記可動部には、
一端が前記折返し部に連接される平板部と、
基部は谷折り部にて前記平板部に連接され、先端部は前記接合部に向かって折り曲げられた前記接点部と、
前記平板部の両側部から側方に延出された一対の引掛け片とが設けられ、
前記引掛け片が挿し込まれる切欠又は穴が設けられて前記接合部の各側部に１枚ずつ立設された一対の係止片を備え、
前記係止片は、前記切欠又は穴に挿し込まれた前記引掛け片を前記平板部の上面が前記接合面と平行になる位置で係止させるが、該係止された前記引掛け片が前記接合部に近づく方向へ変位するのは規制しない
ことを特徴とする。 The surface mount contact according to claim 1,
A joining portion whose lower surface is a joining surface for soldering, a folded portion connected to one end of the joined portion, one end connected to the folded portion, and the other end a free end, the free end side In a surface mount contact comprising a movable part that can be elastically deformed in a direction to approach and move away from the joint part, and a movable part that is partly a contact part for contact conduction,
In the movable part,
A flat plate portion having one end connected to the folded portion;
The base is connected to the flat plate at the valley fold, the tip is bent toward the joint, and the contact portion,
A pair of hook pieces extending laterally from both sides of the flat plate portion are provided,
A notch or hole into which the hook piece is inserted is provided, and a pair of locking pieces are provided upright one by one on each side of the joint portion,
The locking piece locks the hook piece inserted into the notch or hole at a position where the upper surface of the flat plate portion is parallel to the joint surface. Displacement in the direction approaching the joint is not restricted.

請求項１記載の表面実装コンタクトでは、可動部には平板部と接点部とが設けられているが、平板部は、その一端が折返し部に連接され、他方の端部は谷折り部にて接点部の基部に連接されている。この平板部の上面を自動実装機のノズル吸着面として使用することができる。 In the surface mount contact according to claim 1, the movable portion is provided with a flat plate portion and a contact portion, and one end of the flat plate portion is connected to the folded portion, and the other end portion is a valley fold portion. It is connected to the base of the contact part. The upper surface of the flat plate portion can be used as a nozzle suction surface of an automatic mounting machine.

また、平板部の両側部から側方に延出された一対の引掛け片が設けられ、引掛け片が挿し込まれる切欠又は穴が設けられて接合部の各側部に１枚ずつ立設された一対の係止片を備えている。 In addition, a pair of hook pieces extending laterally from both sides of the flat plate portion are provided, and a notch or a hole into which the hook piece is inserted is provided, and one piece is erected on each side portion of the joint portion. A pair of locking pieces.

係止片は、切欠又は穴に挿し込まれた引掛け片を平板部の上面が接合面と平行になる位置で係止させるので、平板部の上面を自動実装機のノズル吸着面として使用することができる。 Since the locking piece locks the hook piece inserted into the notch or the hole at a position where the upper surface of the flat plate portion is parallel to the bonding surface, the upper surface of the flat plate portion is used as the nozzle suction surface of the automatic mounting machine. be able to.

また、引掛け片は切欠又は穴の上縁に係止されることになるので、係止片は係止された引掛け片が接合部に近づく方向へ変位するのは規制しない。つまり、自由端側を接合部に接近させる方向への可動部の弾性変形を阻まないから、可動部は、引掛け片が係止片に係止されて平板部の上面が接合面と平行になる位置を上限とする範囲で、自由端側の昇降変位が可能である。 Further, since the hooking piece is locked to the upper edge of the notch or the hole, the locking piece does not restrict the hooked hooking piece from moving in the direction approaching the joint. In other words, since the elastic deformation of the movable portion in the direction in which the free end side approaches the joint portion is not hindered, the movable portion has the hook piece locked by the latch piece and the upper surface of the flat plate portion is parallel to the joint surface. Up and down displacement on the free end side is possible within the range where the upper limit is the position.

係止片の位置が平板部の側方になるので、特許文献１、２のように接点部の先端側に係止のための構成を配置する必要が無く、その分だけ表面実装コンタクトの全長を抑制できる。 Since the position of the locking piece is on the side of the flat plate part, there is no need to arrange a locking structure on the front end side of the contact part as in Patent Documents 1 and 2, and the total length of the surface mount contact accordingly. Can be suppressed.

しかも、係止片による係止位置が可動部の先端部ではなく、接点部よりも折返し部に近い位置になっているので、接点部の昇降ストロークを大きくできる。
また、表面実装コンタクトの使用状態においては、可動部が接合部に向けて押圧されて圧縮されるので、使用状態における高さは係止片の高さによって規定される。請求項１の表面実装コンタクトでは、係止片が可動部の上方に折り曲げられてはいないので、その折り曲げられた部分の板厚分だけは、使用状態における高さを低減できる。 Moreover, since the locking position by the locking piece is not at the tip of the movable portion but at a position closer to the folded portion than the contact portion, the lifting stroke of the contact portion can be increased.
Further, in the usage state of the surface mount contact, the movable portion is pressed toward the joint portion and compressed, so that the height in the usage state is defined by the height of the locking piece. In the surface mount contact according to the first aspect, since the locking piece is not bent above the movable portion, only the thickness of the bent portion can reduce the height in use.

請求項２記載の表面実装コンタクトは、請求項１記載の表面実装コンタクトにおいて、前記平板部は、山折り部を介して前記折返し部に連接されることを特徴とする。つまり、折返し部と山折り部との２段階の折り曲げになっているので、
接合面（接合部の下面）を半田付けすると、折返し部も半田付けされる。 The surface mount contact according to claim 2 is the surface mount contact according to claim 1, wherein the flat plate portion is connected to the folded portion via a mountain fold portion. In other words, because it is folded in two stages, a folded portion and a mountain fold portion,
When the joint surface (the lower surface of the joint portion) is soldered, the folded portion is also soldered.

この折返し部でフィレット確認をするために半田量が多くされていると、いわゆる半田上がりによって折返し部のばね性が損なわれるおそれがある。しかし、上記の２段階の折り曲げによって、山折り部が可動部のばね支点となるので、たとえ半田上がりが発生しても可動部のばね性は十分に確保される。 If the amount of solder is increased in order to confirm the fillet at the folded portion, the spring property of the folded portion may be impaired due to so-called soldering. However, since the mountain fold portion becomes the spring fulcrum of the movable portion by the above-described two-stage bending, the spring property of the movable portion is sufficiently ensured even if soldering occurs.

従って、折返し部をフィレット確認の領域としても問題はない。しかも、２段階の折り曲げになっているので、上から見たときに折返し部がよく見え、上方からのフィレット確認を行いやすい。 Therefore, there is no problem even if the folded portion is used as a fillet confirmation area. Moreover, since the folding is performed in two stages, the folded portion can be seen well when viewed from above, and the fillet can be easily confirmed from above.

なお、この折返し部の半田量が不足すると剥離強度が不足するおそれがあるが、上記のように、多少過剰であってもよいので、半田量の不足を回避できる。
請求項３記載の表面実装コンタクトは、請求項１記載の表面実装コンタクトにおいて、前記平板部は、前記折返し部側が広幅のテーパ部を介して前記折返し部に連接されることを特徴とする。 If the amount of solder in the folded portion is insufficient, the peel strength may be insufficient. However, as described above, the amount of solder may be slightly excessive, so that an insufficient amount of solder can be avoided.
According to a third aspect of the present invention, in the surface mount contact according to the first aspect, the flat plate portion is connected to the folded portion on the folded portion side through a wide taper portion.

請求項３記載の表面実装コンタクトでは、テーパ部の狭幅端がウィークポイントとなるので、この部分が上記の山折り部と同様に可動部のばね支点となる。従って、請求項２と同様に、たとえ半田上がりが発生しても可動部のばね性は十分に確保される。従って、折返し部をフィレット確認の領域としても問題はない。また、折返し部の半田量が多少過剰であってもよいので、半田量の不足を回避できる。 In the surface mount contact according to the third aspect, since the narrow end of the taper portion serves as a weak point, this portion serves as a spring fulcrum of the movable portion similarly to the mountain fold portion. Therefore, similarly to the second aspect, even if the solder rises, the spring property of the movable portion is sufficiently secured. Therefore, there is no problem even if the folded portion is used as a fillet confirmation area. Further, since the amount of solder in the folded portion may be somewhat excessive, a shortage of solder can be avoided.

請求項４記載の表面実装コンタクトは、請求項３記載の表面実装コンタクトにおいて、前記テーパ部に、請求項２記載の山折り部が設けられていることを特徴とするから、請求項２による効果と請求項３による効果とを併せ持つ。 The surface mount contact according to claim 4 is the surface mount contact according to claim 3, wherein the taper portion is provided with the mountain fold portion according to claim 2. And the effect of claim 3.

請求項５記載の表面実装コンタクトは、請求項１ないし４のいずれか記載の表面実装コンタクトにおいて、前記平板部の上面が前記接合面と平行になっている状態では、前記可動部は前記自由端側を前記接合部に接近させる方向に弾性変形しており、その弾性反発力で前記引掛け片を前記係止片に当接させていることを特徴とする。 The surface mount contact according to claim 5 is the surface mount contact according to any one of claims 1 to 4, wherein the movable portion is the free end when the upper surface of the flat plate portion is parallel to the joint surface. It is elastically deformed in a direction in which the side approaches the joint, and the hooking piece is brought into contact with the locking piece by its elastic repulsive force.

可動部には初期の（荷重がかかっていない状態）でも弾性反発力が存在するので、接点部がシャーシ等に接触してわずかに押圧された状態でも確実に接触導通できる。すなわち、接点部での接触導通を安定的に確保できる可動部（接点部）のストロークの範囲が広い。 Since the movable part has an elastic repulsive force even in the initial stage (in a state where no load is applied), even if the contact part is in contact with the chassis or the like and is pressed slightly, contact conduction can be ensured. That is, the stroke range of the movable part (contact part) that can stably ensure contact conduction at the contact part is wide.

請求項６記載の表面実装コンタクトは、
下面が半田付けのための接合面とされる接合部と、
前記接合部の一端に連接された折返し部と、
一端は前記折返し部に連接され他端は自由端とされて、該自由端側を前記接合部に接近、遠離させる方向に弾性変形可能な可動部であり、一部が接触導通のための接点部とされる可動部とを備える表面実装コンタクトにおいて、
前記可動部には、
一端が前記折返し部に連接される平板部と、
基部は谷折り部にて前記平板部に連接され、先端部は前記接合部に向かって折り曲げられた前記接点部と、
前記平板部の両側部から前記接合部方向に延出された一対の引掛け片とが設けられ、
前記接合部の各側部に１枚ずつ立設され、前記可動部の前記自由端側が設定以上に前記接合部から遠離すると前記引掛け片を係止する一対の係止片を備えた
ことを特徴とする。 The surface mount contact according to claim 6,
A joint where the lower surface is a joint surface for soldering;
A folded portion connected to one end of the joint;
One end is connected to the folded portion and the other end is a free end, and the free end side is a movable portion that can be elastically deformed in a direction to approach and move away from the joint portion, and a part is a contact point for contact conduction In a surface mount contact comprising a movable part that is a part,
In the movable part,
A flat plate portion having one end connected to the folded portion;
The base is connected to the flat plate at the valley fold, the tip is bent toward the joint, and the contact portion,
A pair of hooks extending in the direction of the joint from both side portions of the flat plate portion are provided;
One piece is provided upright on each side part of the joint part, and the free end side of the movable part is provided with a pair of latching pieces that latch the hooking piece when the movable part is separated from the joint part more than set. Features.

平板部の上面が接合面と平行又は略平行になるように設計しておけば、平板部の上面を自動実装機のノズル吸着面として使用することができる。
係止片は、可動部の自由端側が設定以上に接合部から遠離すると引掛け片を係止するので、係止片は係止された引掛け片が接合部に近づく方向へ変位するのは規制しない。つまり、自由端側を接合部に接近させる方向への可動部の弾性変形を阻まないから、可動部は、引掛け片が係止片に係止される位置を上限とする範囲で、自由端側の昇降変位が可能である。 If the upper surface of the flat plate portion is designed to be parallel or substantially parallel to the bonding surface, the upper surface of the flat plate portion can be used as a nozzle suction surface of the automatic mounting machine.
Since the locking piece locks the hook piece when the free end side of the movable part is further away from the joint than the setting, the locking piece is displaced in the direction in which the hooked hook piece approaches the joint. Not regulated. In other words, since the elastic deformation of the movable portion in the direction in which the free end side approaches the joint portion is not hindered, the movable portion has a free end within a range where the upper limit is a position where the hooking piece is locked to the locking piece. Side displacement is possible.

しかも、係止片による係止位置が可動部の先端部ではなく、接点部よりも折返し部に近い位置になっているので、接点部の昇降ストロークを大きくできる。
また、表面実装コンタクトの使用状態においては、可動部が接合部に向けて押圧されて圧縮されるので、使用状態における高さは係止片の高さ、位置、形状などの影響を受ける。請求項６の表面実装コンタクトでは、係止片が可動部の上方に折り曲げられてはいないので、その折り曲げられた部分の板厚分だけは、使用状態における高さを低減できる。また、使用状態において押し込める量が増えることになるので、昇降ストロークが増える。 Moreover, since the locking position by the locking piece is not at the tip of the movable portion but at a position closer to the folded portion than the contact portion, the lifting stroke of the contact portion can be increased.
Further, in the usage state of the surface mount contact, the movable portion is pressed and compressed toward the joint portion, so that the height in the usage state is affected by the height, position, shape, etc. of the locking piece. In the surface mount contact according to the sixth aspect, since the locking piece is not bent above the movable portion, only the thickness of the bent portion can reduce the height in use. In addition, since the amount that can be pushed in in use increases, the lifting stroke increases.

次に、本発明の実施例等により発明の実施の形態を説明する。なお、本発明は下記の実施例等に限定されるものではなく、本発明の要旨を逸脱しない範囲でさまざまに実施できることは言うまでもない。
［実施例１］
まず、図１を参照して本実施例の表面実装コンタクト１の構成を説明する。なお、表面実装コンタクト１は、ばね性金属（例えばリン青銅、ベリリウム銅、ＳＵＳ等）の板金製であり、導電性である。この板金の板厚は０．０８ｍｍ、表面実装コンタクト１の全長（図１（ａ）における左右方向寸法）は３．０ｍｍ、幅（図１（ａ）における上下方向寸法）は１．０ｍｍ）である。 Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example 1]
First, the structure of the surface mount contact 1 of the present embodiment will be described with reference to FIG. The surface mount contact 1 is made of a spring metal (for example, phosphor bronze, beryllium copper, SUS, etc.) and is conductive. The plate thickness of this sheet metal is 0.08 mm, the total length of the surface mount contact 1 (the horizontal dimension in FIG. 1A) is 3.0 mm, and the width (the vertical dimension in FIG. 1A) is 1.0 mm. is there.

表面実装コンタクト１の下部には接合部２が設けられている。接合部２の下面は平坦であり半田付けのための接合面２ａとされる。
接合部２の一端は接合面２ａに対してほぼ直角に折り曲げられて、端部壁３とされている。これとは反対側の端部はＵターン状に折り返されて折返し部４が形成されている。 A junction 2 is provided below the surface mount contact 1. The lower surface of the joint portion 2 is flat and serves as a joint surface 2a for soldering.
One end of the joint portion 2 is bent at a substantially right angle with respect to the joint surface 2 a to form an end wall 3. The end on the opposite side is folded back in a U-turn shape to form a folded portion 4.

その折返し部４には、テーパ部５が連設されている。テーパ部５は折返し部４側が広幅、それとは逆側が狭幅である。また、テーパ部５は上側が凸（接合部２側が凹）に山折りされている。 A taper portion 5 is connected to the folded portion 4. The taper part 5 is wide on the folded part 4 side and narrow on the opposite side. Moreover, the taper part 5 is mountain-folded so that the upper side is convex (the joint part 2 side is concave).

そして、テーパ部５の狭幅の端には平板部６が連接されている。平板部６の他端には上側が凹（接合部２側が凸）に谷折りされて谷折り部７が形成され、この谷折り部７を介して接点部８が連接されている。 A flat plate portion 6 is connected to the narrow end of the taper portion 5. The other end of the flat plate portion 6 is valley-folded so that the upper side is concave (the joint portion 2 side is convex) to form a valley fold portion 7, and the contact portion 8 is connected via the valley fold portion 7.

接点部８は、谷折り部７での谷折りにより、先端側が接合部２から離れる方向に傾斜しているが、先端部は接合部２に向かって半円状に折り曲げられている。この半円状に折り曲げられている部分が接点９となる。 The contact portion 8 is inclined in a direction away from the joint portion 2 due to valley folding at the valley fold portion 7, but the tip portion is bent semicircularly toward the joint portion 2. The part bent in the semicircular shape becomes the contact 9.

また、平板部６の両側部からは一対の引掛け片１１が延出されている。引掛け片１１は、基部において平板部６から接合部２に向かう方向に折り曲げられ、先端部は平板部６と平行な方向に折り曲げられて、平板部６の側方に突出している。 Further, a pair of hook pieces 11 are extended from both side portions of the flat plate portion 6. The hook piece 11 is bent at the base portion in a direction from the flat plate portion 6 toward the joint portion 2, and the tip portion is bent in a direction parallel to the flat plate portion 6 and protrudes to the side of the flat plate portion 6.

これらテーパ部５、平板部６、接点部８及び引掛け片１１が含まれる部分が可動部１２となる。
一方、接合部２の各側部には、それぞれ１枚ずつの係止片１３が立設されている。係止片１３は接合部２に対してほぼ直角に立ち上がっている。２枚の係止片１３は、ともにＬ字を倒立させた形状であるが、腕状部１４の延出方向が折返し部４側を向いているため、互いに鏡像となる形状で対面している。また、腕状部１４の下側には切欠１５が設けられている。 A portion including the taper portion 5, the flat plate portion 6, the contact portion 8, and the hooking piece 11 is a movable portion 12.
On the other hand, one locking piece 13 is erected on each side portion of the joint portion 2. The locking piece 13 rises at a substantially right angle with respect to the joint 2. Both the two locking pieces 13 have a shape in which the L-shape is inverted. However, since the extending direction of the arm-shaped portion 14 faces the folded-back portion 4 side, they face each other in a shape that is a mirror image. . A notch 15 is provided below the arm-like portion 14.

腕状部１４の下側に形成された切欠１５には引掛け片１１が挿し込み状に進入しており、引掛け片１１が腕状部１４に係止されている。これは、図１（ｃ）に示されるように平板部６の上面が接合面２ａと平行になっている状態では、可動部１２は自由端である接点部８側の端部を接合部２に接近させる方向に弾性変形させられており、その弾性反発力で引掛け片１１を係止片１３の腕状部１４に当接させているためである。かりに引掛け片１１が腕状部１４に係止されないとすれば、表面実装コンタクト１は「く」の字状に開いてしまう。 A hooking piece 11 is inserted into a notch 15 formed on the lower side of the arm-like portion 14, and the hooking piece 11 is locked to the arm-like portion 14. This is because, as shown in FIG. 1C, in the state in which the upper surface of the flat plate portion 6 is parallel to the joint surface 2a, the movable portion 12 is connected to the end portion on the contact portion 8 side which is a free end. This is because the hooking piece 11 is brought into contact with the arm-like portion 14 of the locking piece 13 by the elastic repulsive force. If the hooking piece 11 is not locked to the arm-like portion 14, the surface mounting contact 1 opens in a “<” shape.

また、腕状部１４の下側が切欠１５となっていて引掛け片１１が接合部２に近づく方向へ変位（下降変位）するのは阻まれない。
引掛け片１１は図示のように腕状部１４に係止された位置を上限として、表面実装コンタクト１が接合面２ａにてプリント基板に半田付けされた状態にあっては、引掛け片１１がプリント基板に接触する位置を下限として、昇降変位可能である。従って、可動部１２全体としても、この引掛け片１１の昇降変位可能な範囲に対応した範囲で変位可能である。 Further, the lower side of the arm-shaped portion 14 is a notch 15, and the hooking piece 11 is not prevented from being displaced (downwardly displaced) in a direction approaching the joint portion 2.
The hooking piece 11 is in a state where the surface-mounted contact 1 is soldered to the printed board at the joint surface 2a with the position locked to the arm-like portion 14 as the upper limit as shown in the drawing. Can be moved up and down with the position at which it contacts the printed circuit board as the lower limit. Accordingly, the entire movable portion 12 can be displaced within a range corresponding to the range in which the hooking piece 11 can be displaced up and down.

この表面実装コンタクト１は、図２に示すように、プリント基板２０のアースパターン（図示略）上に半田付けされて使用される。
上述した通り、引掛け片１１が腕状部１４に係止されている状態では平板部６の上面が接合面２ａと平行になっているので、平板部６の上面を吸着面として、自動実装機の吸着ノズルにて真空吸着することができる。つまり、表面実装コンタクト１の表面実装を自動実装機によって行うことができる。 As shown in FIG. 2, the surface mount contact 1 is used by being soldered onto a ground pattern (not shown) of the printed circuit board 20.
As described above, since the upper surface of the flat plate portion 6 is parallel to the bonding surface 2a when the hooking piece 11 is locked to the arm-shaped portion 14, automatic mounting is performed using the upper surface of the flat plate portion 6 as the suction surface. Vacuum suction can be performed by the suction nozzle of the machine. That is, the surface mounting of the surface mounting contact 1 can be performed by an automatic mounting machine.

その場合、端部壁３、折返し部４、係止片１３により、接合部２の４方に壁状の立ち上がりが設けられており、これらの立ち上がりがポケット内でガイドとして機能するので表面実装コンタクト１の位置及び姿勢を良好にする。したがって、ポケットと表面実装コンタクト１とのクリアランスを小さくすることができる。また、端面がポケットにくい込んで姿勢不良となるのも防止できる。さらに、立ち上がりの基部には曲げが形成されているので、ポケットからの取り出し時に端面がポケットに引っかかることはなく、取り出しがスムーズになる。こうしたことにより、自動実装の精度が高まる。 In this case, the end wall 3, the folded portion 4, and the locking piece 13 are provided with wall-like rises on the four sides of the joint portion 2, and these rises function as guides in the pockets, so surface mount contacts The position and posture of 1 are made good. Therefore, the clearance between the pocket and the surface mount contact 1 can be reduced. In addition, it is possible to prevent the end face from getting into a pocket and causing a posture failure. Furthermore, since the bend is formed at the rising base, the end face does not get caught in the pocket when taking out from the pocket, and the taking out becomes smooth. This increases the accuracy of automatic mounting.

自動実装機によって表面実装コンタクト１が載せ置かれたプリント基板２０は周知のリフロー半田付け装置に送り込まれ、リフロー半田付けが行われて、表面実装コンタクト１がプリント基板２０上に表面実装される。 The printed circuit board 20 on which the surface mounting contact 1 is placed by an automatic mounting machine is sent to a known reflow soldering apparatus, where reflow soldering is performed, and the surface mounting contact 1 is surface mounted on the printed circuit board 20.

表面実装コンタクト１をプリント基板２０のアースパターン上に半田付けした後に、半田付けの良否を判定するためにフィレット確認が行われるが、端部壁３、折返し部４、係止片１３により、接合部２の４面に曲げが形成されており、これらのすべてをフィレット確認に利用できる。接合部２の４面のいずれでも（いずれか１面以上で）フィレット確認が可能であるから、フィレット確認の作業性が良くなる。 After the surface mount contact 1 is soldered on the ground pattern of the printed circuit board 20, a fillet check is performed to determine whether the soldering is good or not. The end wall 3, the folded portion 4, and the locking piece 13 Bends are formed on the four surfaces of the portion 2, and all of these can be used for the fillet confirmation. Since the fillet can be confirmed on any of the four surfaces of the joint portion 2 (any one or more surfaces), the workability of the fillet confirmation is improved.

特に、折返し部４にはテーパ部５が連設されていて、このテーパ部５が山折り部となっているので、つまり、折返し部４と山折り部との２段階の折り曲げになっている。この折返し部４でフィレット確認をするために半田量が多くされていると、いわゆる半田上がりによって折返し部４のばね性が損なわれるおそれがある。しかし、２段階の折り曲げによって、山折り部が可動部のばね支点となるので、たとえ半田上がりが発生しても可動部１２のばね性は十分に確保される。従って、折返し部４をフィレット確認の領域としても問題はない。しかも、２段階の折り曲げになっているので、上から見たときに折返し部４がよく見え、上方からのフィレット確認を行いやすい。なお、この折返し部４の半田量が不足すると剥離強度が不足するおそれがあるが、上述した理由から多少過剰であってもよいので、半田量の不足を回避できる。 In particular, since the taper portion 5 is connected to the folded portion 4 and the taper portion 5 is a mountain fold portion, that is, the folding portion 4 and the mountain fold portion are folded in two stages. . If the amount of solder is increased in order to confirm the fillet in the folded portion 4, the spring property of the folded portion 4 may be impaired due to so-called soldering. However, since the mountain fold portion becomes a spring fulcrum of the movable portion due to the two-stage bending, the spring property of the movable portion 12 is sufficiently ensured even if the solder rises. Therefore, there is no problem even if the folded portion 4 is used as a fillet confirmation region. Moreover, since the folding is performed in two stages, the folded portion 4 can be seen well when viewed from above, and it is easy to confirm the fillet from above. Note that if the amount of solder in the folded portion 4 is insufficient, the peel strength may be insufficient. However, for the reason described above, the amount may be slightly excessive, so that an insufficient amount of solder can be avoided.

また、この表面実装コンタクト１では、テーパ部５の狭幅端（テーパ部５と平板部６との境界部）がウィークポイントとなるので、この部分が可動部１２のばね支点となる。従って、折返し部４において半田上がりが発生しても可動部１２のばね性は十分に確保される。この点もあって、折返し部４をフィレット確認の領域としても問題はない。 Further, in this surface mount contact 1, the narrow end of the taper portion 5 (the boundary portion between the taper portion 5 and the flat plate portion 6) serves as a weak point, and this portion serves as a spring fulcrum of the movable portion 12. Therefore, even if solder rise occurs in the folded portion 4, the spring property of the movable portion 12 is sufficiently ensured. In view of this point, there is no problem even if the folded portion 4 is used as a fillet confirmation region.

プリント基板２０上に表面実装された表面実装コンタクト１は、プリント基板２０と対面状に配置された接地導体３０（例えばプリント基板２０を覆うシールドケース、プリント基板２０が収容された電子機器の筺体など）とを導通させるために用いられる。 The surface mounting contact 1 that is surface-mounted on the printed circuit board 20 includes a ground conductor 30 (for example, a shield case that covers the printed circuit board 20 and a housing of an electronic device in which the printed circuit board 20 is accommodated). ).

具体的には、プリント基板２０を接地導体３０に接近させることで、接地導体３０にて表面実装コンタクト１の接点部８（接点９）を押圧し、可動部１２を圧迫して図２（ｂ）のように弾性変形させる。この可動部１２の弾性変形に伴う弾性反発力が接点部８（接点９）と接地導体３０とを確実に接触させるので、プリント基板２０（アースパターン）と接地導体３０とが表面実装コンタクト１を介して電気的に導通する。なお、図２（ｂ）では可動部１２の弾性変形を明瞭に示すために係止片１３は図示していない。また、可動部１２が接地導体３０による圧迫を受けていない状態を二点鎖線にて図示している。 Specifically, by bringing the printed circuit board 20 close to the ground conductor 30, the contact portion 8 (contact 9) of the surface mount contact 1 is pressed by the ground conductor 30, and the movable portion 12 is pressed, so that FIG. ) To be elastically deformed. Since the elastic repulsive force accompanying the elastic deformation of the movable portion 12 brings the contact portion 8 (contact point 9) and the ground conductor 30 into contact with each other, the printed circuit board 20 (earth pattern) and the ground conductor 30 connect the surface mount contact 1 to each other. It is electrically connected through. In FIG. 2B, the locking piece 13 is not shown in order to clearly show the elastic deformation of the movable portion 12. Further, a state in which the movable portion 12 is not pressed by the ground conductor 30 is illustrated by a two-dot chain line.

表面実装コンタクト１は、引掛け片１１が係止片１３に係止されて平板部６の上面が接合面２ａと平行になっている状態においては、可動部１２は接点９側を接合部２に接近させる方向に弾性変形しており、その弾性反発力で引掛け片１１を係止片１３に当接させている。つまり、可動部１２には初期の（荷重がかかっていない状態）でも弾性反発力が存在するので、接点部８（接点９）が接地導体３０に接触してわずかに押圧された状態でも確実に接触導通できる。すなわち、接点部８（接点９）での接触導通を安定的に確保できる可動部１２（接点９）のストロークの範囲が広い。 In the surface mount contact 1, when the hooking piece 11 is locked to the locking piece 13 and the upper surface of the flat plate portion 6 is parallel to the bonding surface 2 a, the movable portion 12 has the contact 9 side on the bonding portion 2. The hooking piece 11 is brought into contact with the locking piece 13 by its elastic repulsive force. In other words, since the movable portion 12 has an elastic repulsive force even in the initial state (in a state where no load is applied), the contact portion 8 (contact point 9) is reliably pressed even when it is in contact with the ground conductor 30 and slightly pressed. Contact conduction is possible. That is, the stroke range of the movable portion 12 (contact 9) that can stably ensure contact conduction at the contact 8 (contact 9) is wide.

本実施例の表面実装コンタクト１では、可動部１２には平板部６と接点部８とが設けられているが、平板部６は、その一端が折返し部４に連接され、他方の端部は谷折り部７にて接点部８の基部に連接されている。この平板部６の上面を自動実装機のノズル吸着面として使用することができる。 In the surface mount contact 1 of the present embodiment, the movable portion 12 is provided with a flat plate portion 6 and a contact portion 8. One end of the flat plate portion 6 is connected to the folded portion 4, and the other end portion is The valley fold 7 is connected to the base of the contact 8. The upper surface of the flat plate portion 6 can be used as a nozzle suction surface of an automatic mounting machine.

また、平板部６の両側部から側方に延出された一対の引掛け片１１が設けられ、引掛け片１１が挿し込まれる切欠１５が設けられて接合部２の各側部に１枚ずつ立設された一対の係止片１３を備えている。 In addition, a pair of hooking pieces 11 extending laterally from both sides of the flat plate part 6 are provided, and notches 15 into which the hooking pieces 11 are inserted are provided, one on each side of the joint part 2. A pair of locking pieces 13 are provided one by one.

係止片１３は、切欠１５に挿し込まれた引掛け片１１を平板部６の上面が接合面２ａと平行になる位置で係止させるので、平板部６の上面を自動実装機のノズル吸着面として使用することができる。 The locking piece 13 locks the hooking piece 11 inserted into the notch 15 at a position where the upper surface of the flat plate portion 6 is parallel to the joining surface 2a. Can be used as a surface.

また、引掛け片１１は切欠１５の上縁に係止されることになるので、係止片１３は係止された引掛け片１１が接合部２に近づく方向へ変位するのは規制しない。つまり、自由端側を接合部２に接近させる方向への可動部１２の弾性変形を阻まないから、可動部１２は、引掛け片１１が係止片１３に係止されて平板部６の上面が接合面２ａと平行になる位置を上限とする範囲で、自由端側の昇降変位が可能である。 Further, since the hooking piece 11 is locked to the upper edge of the notch 15, the locking piece 13 does not restrict the hooked hooking piece 11 from being displaced in the direction approaching the joint portion 2. That is, since the elastic deformation of the movable portion 12 in the direction in which the free end side approaches the joint portion 2 is not hindered, the movable portion 12 has the hook piece 11 locked by the locking piece 13 and the upper surface of the flat plate portion 6. Can be displaced up and down on the free end side within the range where the upper limit is the position parallel to the joint surface 2a.

係止片１３の位置が平板部６の側方になっていて、接点部８の先端側に係止のための構成を配置する必要が無いから、その分だけ表面実装コンタクト１の全長を抑制できる。
しかも、係止片１３による係止位置が可動部１２の先端部ではなく、接点部８よりも折返し部４に近い位置になっているので、接点部８（接点９）の昇降ストロークを大きくできる。 Since the position of the locking piece 13 is on the side of the flat plate portion 6 and there is no need to arrange a locking structure on the tip side of the contact portion 8, the entire length of the surface mounting contact 1 is suppressed accordingly. it can.
Moreover, since the locking position by the locking piece 13 is not the tip of the movable portion 12 but the position closer to the folded portion 4 than the contact portion 8, the up / down stroke of the contact portion 8 (contact point 9) can be increased. .

また、表面実装コンタクト１の使用状態においては、可動部１２が接合部２に向けて押圧されて圧縮されるので、使用状態における高さは係止片１３の高さによって規定される。表面実装コンタクト１では、係止片１３が可動部１２の上方に折り曲げられてはいないので、そのように折り曲げられた部分を設けた場合に比べれば、その板厚分だけは、使用状態における高さを低減できる。
［実施例２］
実施例１とは引掛け片及び係止片の形状が異なる例を実施例２として説明する。なお、これら以外の構成は実施例１と共通であるから実施例１と同符号を使用して説明を省略する。 Further, in the use state of the surface mount contact 1, the movable portion 12 is pressed toward the joint portion 2 and compressed, so that the height in the use state is defined by the height of the locking piece 13. In the surface mount contact 1, the locking piece 13 is not bent above the movable portion 12. Therefore, compared to the case where such a bent portion is provided, only the plate thickness is high in the use state. Can be reduced.
[Example 2]
An example in which the shape of the hooking piece and the locking piece is different from that in Example 1 will be described as Example 2. In addition, since structures other than these are common with Example 1, description is abbreviate | omitted using the same code | symbol as Example 1. FIG.

なお、本実施例の表面実装コンタクト１ａも、実施例１と同様にばね性金属（例えばリン青銅、ベリリウム銅、ＳＵＳ等）の板金製であり、導電性である。この板金の板厚は０．０８ｍｍ、表面実装コンタクト１ａの全長（図３（ａ）における左右方向寸法）は３．０ｍｍ、幅（図３（ａ）における上下方向寸法）は１．０ｍｍ）である。 The surface mount contact 1a of the present embodiment is also made of a spring metal (for example, phosphor bronze, beryllium copper, SUS, etc.) as in the first embodiment and is conductive. The sheet metal has a thickness of 0.08 mm, the entire length of the surface mount contact 1a (the horizontal dimension in FIG. 3A) is 3.0 mm, and the width (the vertical dimension in FIG. 3A) is 1.0 mm. is there.

図３に示すように、本実施例の引掛け片２１は、平板部６の両側部から接合部２に向かって延出されている。一方、係止片２３は、接合部２の各側部から平板部６に向かって延出されている。また、接合部２の各側部からは、ガイド片２５、２６も平板部６に向かって延出されている。 As shown in FIG. 3, the hook piece 21 of the present embodiment extends from both side portions of the flat plate portion 6 toward the joint portion 2. On the other hand, the locking piece 23 extends from each side portion of the joint portion 2 toward the flat plate portion 6. Further, guide pieces 25 and 26 are also extended toward the flat plate portion 6 from each side portion of the joint portion 2.

図３の正面図（ｃ）及び背面図に示されるとおり、引掛け片２１と係止片２３及びガイド片２５とは互い違い状に配されている。
そして、引掛け片２１には係止片２３に向かって突出した引掛け突部２２が、係止片２３には引掛け片２１に向かって突出した係止突部２４が、それぞれ設けられている。 As shown in the front view (c) and the rear view of FIG. 3, the hooking piece 21, the locking piece 23, and the guide piece 25 are arranged alternately.
The hooking piece 21 is provided with a hooking protrusion 22 protruding toward the hooking piece 23, and the hooking piece 23 is provided with a hooking protrusion 24 protruding toward the hooking piece 21. Yes.

引掛け突部２２には、下端（先端）側に行くに従って係止片２３に近づく傾斜の下降斜部２２ａが設けられている。係止片２３には、これとは逆に上端（先端）側に行くに従って引掛け片２１に近づく傾斜の上昇斜部２４ａが設けられている。 The hooking protrusion 22 is provided with a descending inclined portion 22a that is inclined toward the locking piece 23 toward the lower end (tip) side. Contrary to this, the locking piece 23 is provided with a rising inclined portion 24a that is inclined toward the hook piece 21 as it goes to the upper end (tip) side.

図３の平面図（ａ）及び底面図（ｅ）に示されるとおり、引掛け片２１と係止片２３及びガイド片２５、２６とは、引掛け片２１を図３における左右方向に平行移動すれば重複してしまう（実際にはあり得ないが）ように配されており、左側面図（ｂ）又は右側面図（ｄ）の投影では、引掛け片２１の投影と係止片２３及びガイド片２５、２６の投影とが重畳する（但し、係止片２３及びガイド片２５、２６の基部付近は除く）。このため、下降斜部２２ａと上昇斜部２４ａとは対面している。 As shown in the plan view (a) and the bottom view (e) of FIG. 3, the hooking piece 21, the locking piece 23, and the guide pieces 25 and 26 translate the hooking piece 21 in the left-right direction in FIG. In this case, in the projection of the left side view (b) or the right side view (d), the projection of the hook piece 21 and the locking piece 23 are arranged. And the projections of the guide pieces 25 and 26 overlap (except for the vicinity of the bases of the locking pieces 23 and the guide pieces 25 and 26). For this reason, the descending inclined portion 22a and the rising inclined portion 24a face each other.

上記のように構成されているので、接点部８（接点９）を接合部２に向けて押圧すると可動部１２が折返し部４を支点として弾性変形して接合部２に接近する。係止片２３及びガイド片２５、２６は、可動部１２の側方に配されているので、この可動部１２の変位がずれるのを防ぐ。 Since it is comprised as mentioned above, if the contact part 8 (contact 9) is pressed toward the junction part 2, the movable part 12 will be elastically deformed by using the folding | returning part 4 as a fulcrum, and will approach the junction part 2. FIG. Since the locking piece 23 and the guide pieces 25 and 26 are arranged on the side of the movable portion 12, the displacement of the movable portion 12 is prevented from shifting.

なお、可動部１２に外力が及ぼされていないときには、平板部６と接合部２とが平行になるように設計されている。
一方、上記とは逆に可動部１２を接合部２から離れさせる方向の力が加えられると、可動部１２が折返し部４を支点として弾性変形して接合部２との間隔が開くが、この可動部１２の変位が設定量に達すると下降斜部２２ａが上昇斜部２４ａに当接し、引掛け片２１が係止片２３に係止される。従って、この方向への可動部１２の変位は引掛け片２１が係止片２３に係止される位置までに規制される。 In addition, when the external force is not exerted on the movable part 12, it is designed so that the flat plate part 6 and the junction part 2 may become parallel.
On the other hand, when a force in a direction that separates the movable portion 12 from the joint portion 2 is applied, the movable portion 12 is elastically deformed with the folded portion 4 as a fulcrum, and the interval between the joint portion 2 is increased. When the displacement of the movable portion 12 reaches a set amount, the descending inclined portion 22a comes into contact with the rising inclined portion 24a, and the hooking piece 21 is engaged with the engaging piece 23. Therefore, the displacement of the movable portion 12 in this direction is restricted to a position where the hook piece 21 is locked to the locking piece 23.

このように、係止片２３は、可動部１２の自由端側が設定以上に接合部から遠離すると引掛け片２１を係止する。しかし、係止片２３は係止された引掛け片２１が接合部に近づく方向へ変位するのは規制しない。つまり、可動部１２の自由端側を接合部２に接近させる方向への可動部１２の弾性変形を阻まないから、可動部１２は、引掛け片２１が係止片２３に係止される位置を上限とする範囲で、自由端側の昇降変位が可能である。 In this way, the locking piece 23 locks the hooking piece 21 when the free end side of the movable portion 12 is farther from the joint than the setting. However, the locking piece 23 does not restrict the locked hook piece 21 from being displaced in a direction approaching the joint. That is, since the elastic deformation of the movable part 12 in the direction in which the free end side of the movable part 12 is brought close to the joint part 2 is not hindered, the movable part 12 is a position where the hook piece 21 is locked by the locking piece 23. Up and down displacement on the free end side is possible within the range where the upper limit is.

本実施例の表面実装コンタクト１ａは、引掛け片１１及び係止片１３に代えて引掛け片２１、係止片２３及びガイド片２５を備える点で実施例１の表面実装コンタクト１とは構成が異なり、次のような効果がある。 The surface mount contact 1a of the present embodiment is different from the surface mount contact 1 of the first embodiment in that a hook piece 21, a lock piece 23, and a guide piece 25 are provided instead of the hook piece 11 and the lock piece 13. However, there are the following effects.

まず、係止片２３及びガイド片２５、２６は、可動部１２の下降変位時にガイドとなる。また、引掛け片２１と係止片２３とで可動部１２の上昇変位を設定範囲に規制できる。
さらに、引掛け片２１、係止片２３及びガイド片２５、２６が左側面図（ｂ）又は右側面図（ｄ）の投影で重畳する設計であるから、かりに可動部１２がねじれていれば、引掛け片２１が係止片２３とガイド片２５とを結ぶ平面から飛び出すので、そのような変形すなわち不良品を発見しやすい。従って、検査工程で上面側だけでなく、側面側からの点検することで不良品を効率よく見つけることとができる。 First, the locking piece 23 and the guide pieces 25 and 26 serve as guides when the movable portion 12 is displaced downward. Further, the upward displacement of the movable portion 12 can be regulated within the set range by the hook piece 21 and the locking piece 23.
Furthermore, since the hook piece 21, the locking piece 23, and the guide pieces 25 and 26 are designed to overlap in the projection of the left side view (b) or the right side view (d), if the movable part 12 is twisted to the scale, Since the hook piece 21 jumps out of the plane connecting the locking piece 23 and the guide piece 25, it is easy to find such a deformation, that is, a defective product. Therefore, defective products can be found efficiently by inspecting not only from the upper surface side but also from the side surface in the inspection process.

また、この表面実装コンタクト１ａは、実施例１の表面実装コンタクト１と同様に使用されるが、実施例１の表面実装コンタクト１と共通の構成により実施例１と同様の効果が発揮される。
［その他］
実施例１では、係止片１３をＬ字形状にしているが、これを門形（「コ」の字状）にしてもよい。門形にした場合、切欠１５に代わって穴が形成され、ここに引掛け片１１の先端部が差し込まれることになるが、このようにしても実施例と同様の効果が得られる。また門形であると、実施例のＬ字形よりも強度的に優れている。 The surface-mount contact 1a is used in the same manner as the surface-mount contact 1 of the first embodiment, but the same effect as that of the first embodiment is exhibited by the same configuration as the surface-mount contact 1 of the first embodiment.
[Others]
In the first embodiment, the locking piece 13 is L-shaped, but it may be gate-shaped ("U" -shaped). In the case of the portal shape, a hole is formed in place of the notch 15 and the tip end portion of the hooking piece 11 is inserted therein. Even in this case, the same effect as in the embodiment can be obtained. In addition, the portal shape is superior in strength to the L-shape of the embodiment.
