Description

本発明は、回路基板用電気コネクタに関する。 The present invention relates to an electric connector for circuit boards.

この種のコネクタにあっては、回路基板の面に対して直角な方向をコネクタ嵌合方向として相手コネクタと接続される際、回路基板の面に平行な方向で相手コネクタが正規位置からずれた位置で嵌合接続されることがあり、そのため、上記ずれを吸収できる、いわゆるフローティングコネクタが広く用いられており、例えば、特許文献１に開示されている。 In this type of connector, when the mating connector is connected to the mating connector with the direction perpendicular to the surface of the circuit board as the connector fitting direction, the mating connector is displaced from the normal position in the direction parallel to the surface of the circuit board. A so-called floating connector that can be fitted and connected at a position and can absorb the above deviation is widely used, and is disclosed in, for example, Patent Document 1.

特許文献１のフローティングコネクタは、四角枠状をなしてその底面で回路基板に固定される固定ハウジング（ハウジング本体）と、該固定ハウジングの四角枠内に位置し該固定ハウジングに対して可動な可動ハウジング（ハウジング接続部）と、該可動ハウジングと上記固定ハウジングに架け渡された状態で配列されている複数の端子（コンタクト）とを有している。上記固定ハウジングは、端子の接続部が回路基板に半田接続されることで、該端子を介して回路基板に固定される。端子は可動ハウジングと固定ハウジングの間の空間に位置する該端子の中間部に略Ｌ字状の弾性部を有していて、該弾性部における弾性変位により上記ずれを吸収する。 The floating connector of Patent Document 1 has a rectangular frame shape and a fixed housing (housing body) fixed to the circuit board at its bottom surface, and a movable movable member that is positioned in the rectangular frame of the fixed housing and movable with respect to the fixed housing. It has a housing (housing connection portion) and a plurality of terminals (contacts) arranged in a state of being bridged over the movable housing and the fixed housing. The fixed housing is fixed to the circuit board via the terminals by connecting the terminal connecting portions to the circuit board by soldering. The terminal has a substantially L-shaped elastic portion at the intermediate portion of the terminal located in the space between the movable housing and the fixed housing, and the displacement is absorbed by elastic displacement of the elastic portion.

特許文献１におけるコネクタの端子は、金属帯状をその板厚方向に屈曲形成したもので、いわゆる曲げ端子であり（特許文献１、段落［００４１］）、該端子は、特許文献１によると、上記固定ハウジングそして可動ハウジングに対し、組み付けることもあるいは一体成形することも可能であるとしている（［段落００５３］）。 The terminal of the connector in Patent Document 1 is a so-called bent terminal, which is formed by bending a metal strip in the plate thickness direction (Patent Document 1, paragraph [0041]). It is possible to assemble or integrally mold the fixed housing and the movable housing ([Paragraph 0053]).

上記端子は、一端側が可動ハウジング内に埋没され、相手コネクタとの接触接続のための接触部が上記可動ハウジングの側面で露呈するように該側面に固定されている。また上記端子は他端側が固定ハウジングで埋没保持されているとともに、その先端が固定ハウジング外に突出していて、回路基板に半田接続される接続部をなしている（図５参照）。 One end side of the terminal is embedded in the movable housing, and the terminal is fixed to the side surface of the movable housing so that a contact portion for contact connection with a mating connector is exposed on the side surface of the movable housing. Further, the other end of the above-mentioned terminal is buried and held in a fixed housing, and its tip projects out of the fixed housing to form a connection portion for solder connection to a circuit board (see FIG. 5).

上記端子の弾性部は、可動ハウジングと固定ハウジングとの間で相手コネクタを受け入れる受入空間に面する溝内で、略Ｌ字状をなしていて、該溝内で弾性変位可能となっている。かかる受入空間を有しているコネクタは、一般にレセプタクルコネクタと称され、相手コネクタがプラグコネクタと称される。 The elastic portion of the terminal has a substantially L shape in a groove facing the receiving space for receiving the mating connector between the movable housing and the fixed housing, and is elastically displaceable in the groove. A connector having such a receiving space is generally called a receptacle connector, and a mating connector is called a plug connector.

特許第４４１１８４３号Patent No. 4411843

しかしながら、特許文献１のコネクタにあっては、相手コネクタと接触接続するための端子の接触部が可動ハウジングの側面に固定的に取り付けられているので、相手コネクタの端子が弾性変位可能な接触部を有していなければならない。特許文献１のレセプタクルコネクタに嵌合接続される相手コネクタたるプラグコネクタは、レセプタクルコネクタとは異なり、端子の接触部はプラグハウジングの外側面に露呈するので、取扱中に思わぬ衝撃力を受けることがあり、該接触部はプラグハウジングの外側面にしっかりと固定されている固定接触部形式であることが望まれ、弾性変位可能な形態は好まれていない。 However, in the connector of Patent Document 1, since the contact portion of the terminal for contact connection with the mating connector is fixedly attached to the side surface of the movable housing, the contact portion of the terminal of the mating connector can be elastically displaced. Must have. Unlike the receptacle connector, the mating connector plug connector that is fitted and connected to the receptacle connector of Patent Document 1 is exposed to the outer surface of the plug housing, so that an unexpected impact force may be applied during handling. However, it is desirable that the contact is in the form of a fixed contact that is firmly fixed to the outer surface of the plug housing, and an elastically displaceable configuration is not preferred.

したがって、特許文献１のレセプタクルコネクタは、相手コネクタがプラグハウジングの外側面に固定された固定接触部形式のプラグコネクタである場合、レセプタクルコネクタ側の端子の接触部が可動ハウジングに対して固定的に取り付けられた固定接触部形式となっていて、弾性変位できないので、上記固定接触部形式のレセプタクルコネクタには対応できない。 Therefore, in the receptacle connector of Patent Document 1, when the mating connector is a fixed contact portion type plug connector fixed to the outer surface of the plug housing, the contact portion of the terminal on the receptacle connector side is fixed to the movable housing. Since it is a fixed contact portion type attached and cannot be elastically displaced, it cannot be applied to the fixed contact portion type receptacle connector.

特許文献１では、端子が弾性部を有していることでフローティングを可能としている。このフローティング可能な端子は、フローティング用の弾性部での弾性変位量を確保するために、端子を細く、薄くする必要がある。しかし、弾性変位量を十分に確保しようとすると、端子は弾性接触部も含めて細く、薄くなってしまい、その結果、弾性接触部は軟らかくなりすぎて、十分接圧が得られなくなってしまう。 In Patent Document 1, the terminal has an elastic portion to enable floating. This floating terminal needs to be thin and thin in order to secure an elastic displacement amount in the floating elastic portion. However, if an attempt is made to secure a sufficient amount of elastic displacement, the terminal including the elastic contact portion becomes thin and thin, and as a result, the elastic contact portion becomes too soft and sufficient contact pressure cannot be obtained.

また、特許文献１によると、端子は一体成形でも可動ハウジングそして固定ハウジングにより保持されることが可能である旨記載されているが、この種のコネクタでは、端子が板厚方向に屈曲形成された曲げ端子であるが、仮に、板厚方向に抜き加工した抜き端子であっても、端子を高密度ピッチで配列する目的で端子幅を小さくした際に、一体成形で保持できるが、端子の接触部を弾性変位可能な形式にしようとすると、端子幅が小さいが故に弾性変位時に相手コネクタとの間の接圧に対し十分に耐えられる強度を確保することが困難となる。 Further, according to Patent Document 1, it is described that the terminal can be held by the movable housing and the fixed housing even if integrally molded, but in the connector of this type, the terminal is bent and formed in the plate thickness direction. Although it is a bent terminal, even if it is a punched terminal that is punched in the plate thickness direction, it can be held by integral molding when the terminal width is reduced for the purpose of arranging the terminals at a high density pitch, but the contact of the terminals If the portion is made to be elastically displaceable, it is difficult to ensure sufficient strength to withstand the contact pressure with the mating connector during elastic displacement because the terminal width is small.

本発明は、かかる事情に鑑み、フローティング可能なコネクタにあっても、端子の接触部で十分な接圧を確保し、さらには、端子を高密度配列するために端子幅の小さい端子をハウジングと一体成形した場合でも、この端子幅の小さい端子に、弾性変位可能な接触部をもたせ、弾性変位しない固定接触部形式の端子をもつ相手コネクタに対しても対応できる回路基板用電気コネクタを提供することを課題とする。 In view of such circumstances, the present invention ensures a sufficient contact pressure at the contact portion of the terminal even in a floating connector, and further, in order to arrange the terminals at a high density, the terminals having a small terminal width are connected to the housing. (EN) Provided is an electrical connector for a circuit board, which is capable of coping with a mating connector having a fixed contact portion type terminal which does not elastically displace, by providing the terminal having a small terminal width with a contact portion capable of elastic displacement even when integrally molded. This is an issue.

本発明に係る回路基板用電気コネクタは、回路基板の面に固定取付けされる固定ハウジングと、該固定ハウジングに対して可動な可動ハウジングと、固定ハウジングと可動ハウジングに架け渡されて配列された複数の端子とを有し、固定ハウジングで保持される固定側被保持部と、可動ハウジングで保持される可動側被保持部と、固定側被保持部と可動側被保持部の間に位置する中間弾性部とを有している。 An electrical connector for a circuit board according to the present invention includes a fixed housing fixedly mounted on the surface of the circuit board, a movable housing movable with respect to the fixed housing, and a plurality of fixed housings arranged between the fixed housing and the movable housing. A fixed-side held portion held by a fixed housing, a movable-side held portion held by a movable housing, and an intermediate portion located between the fixed-side held portion and the movable-side held portion. And an elastic portion.

かかる回路基板用電気コネクタにおいて、本発明では、端子は、固定側被保持部より延び固定ハウジング外に位置する一端部に設けられ回路基板へ接続される接続部と、固定側被保持部よりも端子の他端側位置で、可動ハウジングに形成された溝部内で移動可能に収められた接触腕部とを有し、接触腕部が接触部でつながり弾性のある二つの腕部を有し、二つの腕部のそれぞれの基部に上記可動側被保持部が形成されていて、固定側被保持部が固定ハウジングで、そして可動側被保持部が可動ハウジングで、保持されていることを特徴としている。 In such an electric connector for a circuit board, according to the present invention, the terminal is connected to the circuit board provided at one end portion extending from the fixed side held portion and located outside the fixed housing, and the terminal is more than the fixed side held portion. At the other end side position of the terminal, has a contact arm portion movably accommodated in a groove formed in the movable housing, the contact arm portion has two elastic arm portions connected by the contact portion, The movable side held portion is formed on each of the base portions of the two arm portions, the fixed side held portion is held by a fixed housing, and the movable side held portion is held by a movable housing. There is.

かかる構成の本発明では、二つの腕部をもつ接触腕部がそれぞれの腕部の基部にて一体成形で可動ハウジングにより保持され、接触部でつながる二つの腕部が上記基部以外の部分で弾性変位可能なので、腕部の弾性変位可能部分を長く確保しつつ、接触部での接圧を大きくできる。また接触腕部は、両方の基部で保持されるので該接触腕部の強度が大となる。 In the present invention having such a configuration, the contact arm portion having the two arm portions is integrally molded at the base portion of each arm portion and held by the movable housing, and the two arm portions connected by the contact portion are elastic at portions other than the base portion. Since it is displaceable, the contact pressure at the contact portion can be increased while ensuring the elastically displaceable portion of the arm portion for a long time. Further, since the contact arm portion is held by both the base portions, the strength of the contact arm portion is high.

本発明において、固定ハウジングは、可動ハウジングが回路基板から離れる方向での可動量を規制する規制金具が取り付けられているようにすることができる。こうすると、規制金具で、相手コネクタ抜出時に可動ハウジングの抜出方向移動を規制するので端子の保護につながる。 In the present invention, the fixed housing may be provided with a restriction fitting for restricting the movable amount of the movable housing in the direction away from the circuit board. In this case, the restricting metal member restricts the movement of the movable housing in the extraction direction when the mating connector is extracted, which leads to protection of the terminal.

本発明において、規制金具は、可動ハウジングの一部における上面に対して対面する規制部と、該規制部から延び回路基板に固定接続される複数の固定脚部とを有しているようにすることができる。かかる形態では、規制金具に複数の固定脚部が設けられるので、規制金具を保持する力が大となり、ひいては、可動ハウジングの規制能力が大となる。さらに、固定脚部を通して回路基板との電気的導通も可能となる。 In the present invention, the restriction fitting has a restriction portion facing a top surface of a part of the movable housing, and a plurality of fixed leg portions extending from the restriction portion and fixedly connected to the circuit board. be able to. In this mode, since the plurality of fixed legs are provided on the restriction fitting, the force for holding the restriction fitting becomes large, and the restriction capacity of the movable housing becomes large. Furthermore, electrical connection with the circuit board is also possible through the fixed legs.

本発明において、規制金具の規制部は端子配列方向に直角なコネクタ幅方向に延びる平帯状をなし、複数の固定脚部が、コネクタ幅方向における該規制部の両端部の位置そして中間部の位置に設けられているようにすることができる。こうすると、平帯状の規制部の中間部にも固定脚部を備えているので、コネクタの高さ方向寸法を大きくすることなく、規制金具を保持する規制能力が大となる。 In the present invention, the restricting portion of the restricting metal member has a flat strip shape extending in the connector width direction perpendicular to the terminal arrangement direction, and the plurality of fixed leg portions are located at both end positions and intermediate position of the restricting portion in the connector width direction. Can be provided in. In this case, since the fixed leg portion is also provided in the intermediate portion of the flat belt-shaped regulation portion, the regulation ability to hold the regulation metal member becomes large without increasing the size in the height direction of the connector.

以上のように、本発明は、接触部でつながり弾性のある二つの腕部を有する接触腕部を端子に設け、二つの腕部の基部で可動ハウジングとの一体成形により該可動ハウジングにより保持することとしたので、フローティング可能なコネクタであっても二つの腕部は大きく弾性変位が可能で接触部での十分な弾性変位量を確保しつつ、接触部を挟むように二つの腕部を有するので、接触部での接圧に対する強度が向上し、しかもそれらの二つの腕部の基部で可動ハウジングにより保持されることで上記接触腕部の保持強度も向上する。 As described above, according to the present invention, the terminal is provided with the contact arm portion having the two elastic portions that are connected to each other at the contact portion, and the base portions of the two arm portions are integrally molded with the movable housing and held by the movable housing. Therefore, even if it is a floating connector, the two arm portions can undergo large elastic displacement, and while maintaining a sufficient elastic displacement amount at the contact portion, the two arm portions have the two arm portions so as to sandwich the contact portion. Therefore, the strength against the contact pressure at the contact portions is improved, and the holding strength of the contact arm portions is also improved by being held by the movable housing at the base portions of these two arm portions.

図２に見られるように、レセプタクルコネクタ１の固定ハウジング１１と可動ハウジング２１には、受入空間１Ａを形成する固定ハウジング１１の側壁１２の内面と可動ハウジング２１の側壁に、それぞれ端子溝１３そして端子溝２２とを対向するように配列形成されている。また、可動ハウジング２１は、該可動ハウジング２１の端子溝２２同士間に形成された溝壁２３の下端が固定ハウジング１１の方に向け延びてリブ２３Ａを形成している。複数の溝壁２３の下端に位置するすべてのリブ２３Ａはレセプタクルコネクタ１の受入空間１Ａの底部に位置し、該可動ハウジング２１の長手方向に延びる底部保持部２４を形成している。上記可動ハウジング２１は、端子溝２２の配列方向両端に、該可動ハウジング２１の下部から上記端子溝２２の配列方向に突出する段付板状の被規制部２５が設けられている（図３参照）。 As shown in FIG. 2, in the fixed housing 11 and the movable housing 21 of the receptacle connector 1, the inner surface of the side wall 12 of the fixed housing 11 forming the receiving space 1A and the side wall of the movable housing 21 are respectively provided with the terminal groove 13 and the terminal. The grooves 22 are arranged so as to face each other. Further, in the movable housing 21, a lower end of a groove wall 23 formed between the terminal grooves 22 of the movable housing 21 extends toward the fixed housing 11 to form a rib 23A. All the ribs 23A located at the lower ends of the plurality of groove walls 23 are located at the bottom of the receiving space 1A of the receptacle connector 1 and form a bottom holding portion 24 extending in the longitudinal direction of the movable housing 21. The movable housing 21 is provided with stepped plate-shaped regulated portions 25 projecting from the lower portion of the movable housing 21 in the arrangement direction of the terminal grooves 22 at both ends in the arrangement direction of the terminal grooves 22 (see FIG. 3 ). ).

一方、レセプタクルコネクタ１の端子３０は、本実施形態では、金属帯体をその板厚方向に屈曲された、いわゆる曲げ端子の形態をなしている。本発明では、端子は曲げ端子のみならず、金属板をその板厚方向に抜いた形態をなす、いわゆる抜き端子であってもよい。 On the other hand, the terminal 30 of the receptacle connector 1 is in the form of a so-called bent terminal in which the metal strip is bent in the plate thickness direction in the present embodiment. In the present invention, the terminal is not limited to a bent terminal, and may be a so-called punched terminal in which a metal plate is pulled out in the plate thickness direction.

上記端子３０は、図２、図４そして図５（Ａ）に見られるように、全体として二つの逆Ｕ字状部をもつ略波形をなし、固定ハウジング１１の側壁１２側に位置する一方の逆Ｕ字状部が中間弾性部３１をなし側壁１２に形成された端子溝１３内に収められている。また、可動ハウジング２１側に位置する他方の逆Ｕ字状部は、二つの腕部３２Ａ，３２Ｂを有する接触腕部３２を形成している。該二つの腕部３２Ａ，３２Ｂは該腕部３２Ａ，３２Ｂの基部を除いて、それらの殆どの部分が可動ハウジング２１の端子溝２２内に収められており、上記腕部３２Ａ，３２Ｂはそれらの上部で接触部３３によりつながっている。該接触部３３は上記端子溝２２外に突出するように凸湾曲形成されている。 As shown in FIGS. 2, 4 and 5(A), the terminal 30 has a substantially corrugated shape having two inverted U-shaped portions as a whole, and one of the terminals 30 is located on the side wall 12 side of the fixed housing 11. The inverted U-shaped portion forms the intermediate elastic portion 31 and is housed in the terminal groove 13 formed in the side wall 12. The other inverted U-shaped portion located on the movable housing 21 side forms a contact arm portion 32 having two arm portions 32A and 32B. Most of the two arm portions 32A, 32B except the base portions of the arm portions 32A, 32B are housed in the terminal groove 22 of the movable housing 21, and the arm portions 32A, 32B are the same as those of the arm portions 32A, 32B. The upper part is connected by the contact portion 33. The contact portion 33 is formed in a convex curve so as to project to the outside of the terminal groove 22.

端子３０の上記中間弾性部３１が端子溝１３の奥側に位置する腕部の下端からは斜めに延びる固定側被保持部３４をなしていて、該固定側被保持部３４は固定ハウジング１１の側壁１２の下部にて一体成形により埋没保持されており、該固定側被保持部３４からは該端子３０の一端側が延出していて上記側壁１２外にあり該側壁１２の下面に沿って位置しており、この一端側が回路基板への半田接続のための接続部３５を形成する。 The intermediate elastic portion 31 of the terminal 30 forms a fixed side held portion 34 that extends obliquely from the lower end of the arm portion located on the inner side of the terminal groove 13, and the fixed side held portion 34 of the fixed housing 11 is provided. The terminal 30 is embedded and held in the lower part of the side wall 12 by integral molding, and one end side of the terminal 30 extends from the fixed side held portion 34 and is located outside the side wall 12 and located along the lower surface of the side wall 12. This one end side forms a connection portion 35 for solder connection to the circuit board.

上記接触腕部３２はその二つの腕部３２Ａ，３２Ｂのうち、端子溝２２の奥側に位置する腕部３２Ａの下端部をなす基部３２Ａ−１がＬ字状に屈曲されていて、可動ハウジング２１の下部にて一体成形により埋没保持されている。これに対し、端子溝２２の開口側に位置する腕部３２Ｂがその下端部をなす基部３２Ｂ−１をＬ字状に屈曲して上記可動ハウジングの底部保持部２４を貫通していて、中間弾性部３１の二つの腕部のうち端子溝１３の開口側に位置する腕部の下端とつながっている。上記腕部３２Ｂの基部３２Ｂ−１は可動側被固定部３６をなしていて上記底部保持部２４との一体成形により保持されている。 Of the two arm portions 32A and 32B, the contact arm portion 32 has a base portion 32A-1 which is a lower end portion of the arm portion 32A located on the far side of the terminal groove 22 and is bent in an L-shape, so that the movable housing is movable. It is embedded and held in the lower part of 21 by integral molding. On the other hand, the arm portion 32B located on the opening side of the terminal groove 22 bends the lower end portion of the base portion 32B-1 into an L-shape to penetrate the bottom holding portion 24 of the movable housing, and the intermediate elasticity Of the two arm portions of the portion 31, it is connected to the lower end of the arm portion located on the opening side of the terminal groove 13. A base portion 32B-1 of the arm portion 32B constitutes a movable side fixed portion 36 and is held by integral molding with the bottom portion holding portion 24.

上記端子３０は、上述のように、接触部３３でつながり逆Ｕ字状をなす接触腕部３２の二つの腕部３２Ａ，３２Ｂは、それらの基部３２Ａ−１，３２Ｂ−１が可動ハウジング２１による一体成形で保持されていて、該基部３２Ａ−１，３２Ｂ−１よりも上方の逆Ｕ字状部分は、何ら拘束を受けておらず、弾性変位が可能となっている。もちろん中間弾性部３１も何ら拘束を受けていないので、弾性変位が可能である。 As described above, in the terminal 30, the two arm portions 32A and 32B of the contact arm portion 32 that are connected by the contact portion 33 and form the inverted U shape have the base portions 32A-1 and 32B-1 by the movable housing 21. The inverted U-shaped portion, which is held by integral molding and is above the base portions 32A-1 and 32B-1, is not constrained at all and is elastically displaceable. Of course, since the intermediate elastic portion 31 is not restrained at all, elastic displacement is possible.

固定ハウジング１１により保持されている金属板製の規制金具４０は、固定ハウジング１１を省略して可動ハウジング２１、端子３０そして規制金具４０を示す図３に見られるように、可動ハウジング２１の既述の被規制部２５の上面に面しコネクタ幅方向に延びる平帯状の規制部４１と、該規制部４１から延出する固定脚部４２とを有している。固定脚部４２は、上記規制部４１の両端と側部に設けられているが、いずれも、下方に向けクランク状に屈曲されていて、下端部が回路基板の対応部に半田固定されるようになっている。 The metal plate restricting metal fitting 40 held by the fixed housing 11 is shown in FIG. It has a flat-belt-shaped regulating portion 41 facing the upper surface of the regulated portion 25 and extending in the connector width direction, and a fixed leg portion 42 extending from the regulating portion 41. The fixed leg portions 42 are provided on both ends and side portions of the restriction portion 41, but both are bent downward in a crank shape so that the lower end portions are soldered and fixed to the corresponding portions of the circuit board. It has become.

このような規制金具４０は、可動ハウジング２１の被規制部２５と面する規制部４１のうち上記固定脚部４２が位置する縁部と、固定脚部４２の基部が固定ハウジング１１内に一体成形により埋没されていて該固定ハウジング１１の一体成形により保持されている。換言すれば、固定ハウジング１１にて埋没保持されている部分以外は露呈している。 In such a restriction fitting 40, an edge portion of the restriction portion 41 facing the restricted portion 25 of the movable housing 21 where the fixed leg portion 42 is located and a base portion of the fixed leg portion 42 are integrally formed in the fixed housing 11. And is held by being integrally molded with the fixed housing 11. In other words, the parts other than the part buried and held in the fixed housing 11 are exposed.

かかる規制金具４０は、その一部で可動ハウジング２１で一体成形により保持されるので、圧入による保持にくらべ、規制金具の圧入シロを考慮しなくてよいので省スペース化できるとともに、圧入方向に拘束されないので規制金具の形状を簡略化でき、この点でも省スペース化につながる。 Since a part of the restriction fitting 40 is integrally molded and held by the movable housing 21, it is not necessary to consider the press-fitting white of the restriction fitting as compared with holding by press-fitting, so that space can be saved and the restriction fitting 40 can be restrained in the press-fitting direction. Since this is not done, the shape of the restriction fitting can be simplified, which also leads to space saving.

かかる形態のレセプタクルコネクタ１は、次の要領で使用される。先ず、該レセプタクルコネクタ１は、その端子３０の接続部３５が回路基板（図示せず）の対応回路部に半田接続され、また規制金具４０の固定脚部４２が上記回路基板の対応部に半田固定される。 The receptacle connector 1 having such a form is used in the following manner. First, in the receptacle connector 1, the connection portion 35 of the terminal 30 is soldered to a corresponding circuit portion of a circuit board (not shown), and the fixed leg portion 42 of the restriction fitting 40 is soldered to a corresponding portion of the circuit board. Fixed.

一方、プラグコネクタ２も、レセプタクルコネクタ１と同様に、該プラグコネクタ２の端子６０の接触部６２にて他の回路基板（図示せず）の対応回路部に半田接続される。 On the other hand, similarly to the receptacle connector 1, the plug connector 2 is also soldered to the corresponding circuit portion of another circuit board (not shown) at the contact portion 62 of the terminal 60 of the plug connector 2.

かかる後、上記他の回路基板に取り付けられたプラグコネクタ２を、図１そして図５に見られるごとく、上記他の回路基板を上方とした姿勢、すなわち、プラグコネクタ２の凹部５１Ａを下方に開口する姿勢で、上記回路基板に取り付けられたレセプタクルコネクタ１の直上位置にもたらし、そのまま下降する。 After that, the plug connector 2 attached to the other circuit board is in a posture with the other circuit board facing upward, that is, the recess 51A of the plug connector 2 is opened downward, as seen in FIGS. 1 and 5. In such a posture, it is brought to a position directly above the receptacle connector 1 attached to the circuit board, and then lowered as it is.

プラグコネクタ２を降下すると、該プラグコネクタ２の凹部５１Ａにレセプタクルコネクタ１の可動ハウジング２１が端子３０の接触腕部３２とともに進入するようにして、プラグコネクタ２がレセプタクルコネクタ１の受入空間１Ａに受け入れられる（図５（Ｂ）参照）。 When the plug connector 2 is lowered, the movable housing 21 of the receptacle connector 1 enters the recess 51A of the plug connector 2 together with the contact arm portion 32 of the terminal 30 so that the plug connector 2 is received in the receiving space 1A of the receptacle connector 1. (See FIG. 5B).

図５（Ｂ）に見られるように、プラグコネクタ２がその下端でレセプタクルコネクタ１の底部保持部２４に当接する所定深さまで嵌合すると、プラグコネクタ２に設けられた二列の端子６０は、レセプタクルコネクタ１の二列の端子３０の接触部３３とコネクタ幅方向で内側から当接する。上記接触部３３は、弾性を有する二つの腕部３２Ａ，３２Ｂから成る接触腕部３２の上部に位置しており、上記二つの腕部３２Ａ，３２Ｂの弾性撓み変位による付勢力をもってプラグコネクタの端子６０の接触部６２に接触する。 As shown in FIG. 5B, when the plug connector 2 is fitted to a predetermined depth where it abuts the bottom holding portion 24 of the receptacle connector 1 at its lower end, the two rows of terminals 60 provided on the plug connector 2 are The contact portions 33 of the two rows of terminals 30 of the receptacle connector 1 come into contact with each other from inside in the connector width direction. The contact portion 33 is located above the contact arm portion 32 composed of two elastic arm portions 32A and 32B, and has a biasing force due to elastic bending displacement of the two arm portions 32A and 32B. The contact portion 62 of 60 is contacted.

ここで、例えば、プラグコネクタ２がレセプタクルコネクタ１に対して、所定位置から左右方向でずれた位置でレセプタクルコネクタ１に嵌合されたとすると、そのずれの分だけ、上記レセプタクルコネクタ１の対をなす二つの端子３０の一方の端子の中間弾性部３１がその逆Ｕ字状をなす両脚を開脚するように弾性変位し、他方の端子の中間弾性部がその逆Ｕ字状をなす両脚を閉脚するように弾性変位することで、上記プラグコネクタ２の移動を可能とし、いわゆるフローティングがなされる。 Here, for example, if the plug connector 2 is fitted into the receptacle connector 1 at a position deviated from the predetermined position in the left-right direction with respect to the receptacle connector 1, the receptacle connector 1 makes a pair by the amount of the deviation. The intermediate elastic portion 31 of one of the two terminals 30 is elastically displaced so as to open both legs of the inverted U shape, and the intermediate elastic portion of the other terminal closes both legs of the inverted U shape. By elastically displacing so that the plug connector 2 can be moved, so-called floating is performed.

上記フローティングの様子は、図６（Ａ），（Ｂ）で良く理解できる。図６（Ａ），（Ｂ）はコネクタ１を上方から見た図であり、図６（Ａ）は可動ハウジング２１が固定ハウジング１１に対し正規位置にある場合、図６（Ｂ）は可動ハウジング２１が固定ハウジング１１に対しフローティングしている位置にある場合を示している。図６（Ａ）では、可動ハウジング２１は固定ハウジング１１に対し、上下そして左方方向のいずれでも対称な正規位置にある。この正規位置では、可動ハウジング２１は、図６（Ａ）の上下部分で見られるように、固定ハウジング１１との間に隙間δを等しく形成し、可動ハウジング２１の左右の被規制部２５は、同じ面積で規制金具４０の規制部４１により規制を受けている。このことは、上方から見て、規制部４１と当接していない被規制部２５が左右で同面積として表われていることから良くわかる。 The above floating state can be well understood from FIGS. 6(A) and 6(B). 6(A) and 6(B) are views of the connector 1 viewed from above. FIG. 6(A) shows a case where the movable housing 21 is in the regular position with respect to the fixed housing 11, and FIG. 6(B) shows a movable housing. 21 shows the case where 21 is in a floating position with respect to the fixed housing 11. In FIG. 6(A), the movable housing 21 is in a normal position symmetrical with respect to the fixed housing 11 in both the vertical direction and the leftward direction. In this normal position, the movable housing 21 has an equal gap δ between the movable housing 21 and the fixed housing 11, as seen in the upper and lower portions of FIG. 6A, and the left and right regulated portions 25 of the movable housing 21 are The same area is regulated by the regulation portion 41 of the regulation metal fitting 40. This can be seen clearly from the fact that the regulated portion 25 that is not in contact with the regulating portion 41 has the same area on the left and right when viewed from above.

一方、フローティング状態の図６（Ｂ）では、固定ハウジング１１に対して可動ハウジング２１が右上方に向け斜めに移動している。すなわち、図６（Ａ）における上方の隙間δはなくなっており、下方の隙間が増大している。さらに、左右方向では、右方の被規制部２５は左方の被規制部２５にくらべ大きい面積で規制部４１と当接した状態で該規制部４１により規制されている。換言すれば、左方の被規制部２５が規制を受けていない面積を図６（Ａ）の状態に比し小さくしている。このフローティングは図６（Ｂ）に見られるように、端子３０の弾性部３１の弾性変形によって可能となっている。 On the other hand, in FIG. 6B in the floating state, the movable housing 21 is diagonally moved to the upper right with respect to the fixed housing 11. That is, the upper gap δ in FIG. 6(A) is eliminated and the lower gap is increased. Further, in the left-right direction, the regulated portion 25 on the right side is regulated by the regulated portion 41 while being in contact with the regulated portion 41 in a larger area than the regulated portion 25 on the left side. In other words, the area where the regulated portion 25 on the left side is not regulated is made smaller than that in the state of FIG. This floating is made possible by elastic deformation of the elastic portion 31 of the terminal 30, as shown in FIG.

上記レセプタクルコネクタ１の端子３０は、プラグコネクタ２が正規位置で嵌合しても、あるいはずれをもって嵌合しても、該端子３０の接触腕部３２は、それらの二つの腕部３２Ａ，３２Ｂの基部で可動ハウジング２１との一体成形でしっかりと保持されていながらも、該基部から上方に十分に長く延びているので、プラグコネクタ２の端子６０との間の弾性変位による接圧を十分大きく確保できる。 The contact arm portion 32 of the terminal 30 of the receptacle connector 1 has the two contact arm portions 32A and 32B regardless of whether the plug connector 2 is fitted in the regular position or is fitted with a deviation. While being firmly held integrally with the movable housing 21 at the base portion of the plug connector 2, since it extends sufficiently upward from the base portion, the contact pressure due to elastic displacement with the terminal 60 of the plug connector 2 is sufficiently large. Can be secured.

このように、レセプタクルコネクタ１の端子３０はその接触部３３で大きな接圧をもってプラグコネクタ２の端子６０と接触しているので、プラグコネクタ２を抜出する際には、レセプタクルコネクタ１は上記接触部３３にて大きな摩擦力が抜出方向に作用し、可動ハウジング２１はその力によって上方に移動して可動量を増大しようとする傾向を示す。 As described above, the terminal 30 of the receptacle connector 1 is in contact with the terminal 60 of the plug connector 2 with a large contact pressure at the contact portion 33 thereof. Therefore, when the plug connector 2 is pulled out, the receptacle connector 1 contacts the above contact. A large frictional force acts on the portion 33 in the extraction direction, and the movable housing 21 tends to move upward due to the force to increase the movable amount.

本実施形態では、固定ハウジング１１に規制金具４０が保持されており、該規制金具４０の規制部４１が可動ハウジング２１の被規制部２５の上面に面するように位置している。したがって、プラグコネクタ２の抜出時に、可動ハウジング２１が端子３０の接触部３３での摩擦力で上方に引かれても、上記被規制部２５が規制部４１に当接して上方移動が規制される。上記規制部４１は、プラグコネクタ２の抜出前の当初から被規制部２５の上面と接触していても、あるいは当初被規制部２５の上面との間に隙間があってもよい。 In this embodiment, the restricting metal fitting 40 is held by the fixed housing 11, and the restricting portion 41 of the restricting metal fitting 40 is positioned so as to face the upper surface of the regulated portion 25 of the movable housing 21. Therefore, even when the movable housing 21 is pulled upward by the frictional force at the contact portion 33 of the terminal 30 when the plug connector 2 is pulled out, the regulated portion 25 comes into contact with the regulating portion 41 and the upward movement is regulated. It The regulation portion 41 may be in contact with the upper surface of the regulated portion 25 from the beginning before the plug connector 2 is pulled out, or there may be a gap between the regulation portion 41 and the upper surface of the regulated portion 25 initially.

上記規制金具４０は固定ハウジング１１により一体成形で強固に保持されているが、該規制金具４０自体でも、その複数の固定脚部４２で回路基板に半田固定されているので、上記規制部４１で可動ハウジング２１からの上方に向けた力を受けても十分な強度をもって、該可動ハウジング２１の上方への可動量を規制する。 Although the restriction fitting 40 is integrally molded and firmly held by the fixed housing 11, the restriction fitting 40 itself is solder-fixed to the circuit board by the plurality of fixed leg portions 42, so that the restriction portion 41 is fixed. Even if an upward force is applied from the movable housing 21, the upward movement amount of the movable housing 21 is regulated with sufficient strength.

本発明は、図１ないし図６に図示した例に限定されず、種々変形が可能である。 The present invention is not limited to the examples shown in FIGS. 1 to 6, and various modifications are possible.

例えば、既出のレセプタクルコネクタ１の端子３０は、対向している一対の端子３０同士が別部材であったが、互いに連結されている一部材として形成されていてもよい。図６（Ａ）の場合、可動ハウジング２１に対し、左右に接触部３３を有する端子３０は一部材であり、接触部３３から下方に向け一方の腕部３２Ａがそして横方向に向け他方の腕部３２Ｂが延びている形態の接触腕部３２となっている。一方の腕部３２Ａの基部は、既出の形態の場合と同様に可動ハウジング２１の底部保持部２４により保持され、他方の腕部３２Ｂの基部は可動ハウジング２１の中央壁の上部で保持されている。 For example, in the terminal 30 of the receptacle connector 1 described above, the pair of terminals 30 facing each other are separate members, but they may be formed as one member connected to each other. In the case of FIG. 6A, the terminal 30 having the contact portions 33 on the left and right with respect to the movable housing 21 is one member, and one arm portion 32A is directed downward from the contact portion 33 and the other arm is oriented laterally. The contact arm portion 32 has a shape in which the portion 32B extends. The base portion of the one arm portion 32A is held by the bottom portion holding portion 24 of the movable housing 21 as in the case of the above-described form, and the base portion of the other arm portion 32B is held by the upper portion of the central wall of the movable housing 21. ..

かかる図７（Ａ）の端子３０を、対をなす二つの端子３０に分離することも可能である。例えば、図７（Ｂ）のように、他方の腕部３２Ｂを左右の接触部３３の間で切断した形態として、上記他方の腕部の基部を可動ハウジング２１のＴ字断面形状の中央型の上部で保持することとしている。 It is also possible to separate the terminal 30 of FIG. 7A into two terminals 30 forming a pair. For example, as shown in FIG. 7B, the other arm portion 32B is cut between the left and right contact portions 33, and the base portion of the other arm portion is a central type having a T-shaped cross section of the movable housing 21. It is supposed to be held at the top.
