Description

本発明は、フローティング機構を有する電気コネクタに関する。   The present invention relates to an electrical connector having a floating mechanism.

従来より、回路基板に固定された電気コネクタのハウジングと、相手コネクタのハウジングや電子機器の筐体などといった被嵌合部材との嵌合にあたっては、電気コネクタのハウジングと被嵌合部材との間に少しでも位置ずれや誤差があると嵌合しにくくなるという問題があった。   Conventionally, when fitting an electrical connector housing fixed to a circuit board and a mating member such as a mating connector housing or a housing of an electronic device, the electrical connector between the housing and the mating member However, there is a problem that it is difficult to fit if there is any positional deviation or error.

このような問題に対処するため、位置ずれを吸収するフローティング機構を有する電気コネクタが開発され、実用化されている。フローティング機構を有する電気コネクタを用いることにより、電気コネクタのハウジングと被嵌合部材との間に多少の位置ずれや誤差（但し、フローティング機構における許容可動範囲内の位置ずれや誤差）があっても、その位置ずれや誤差がフローティング機構によって吸収され、電気コネクタのハウジングと被嵌合部材とを容易に嵌合することができる。   In order to cope with such a problem, an electrical connector having a floating mechanism that absorbs misalignment has been developed and put into practical use. By using an electrical connector having a floating mechanism, even if there is a slight misalignment or error between the housing of the electrical connector and the mating member (however, a misalignment or error within the allowable movable range of the floating mechanism). The displacement and error are absorbed by the floating mechanism, and the housing of the electrical connector and the member to be fitted can be easily fitted.

フローティング機構を有する電気コネクタとして、例えば、２体のハウジングの各々に固定された２つの固定部と、それら２つの固定部間に形成された弾性部とを有するコンタクトを備えたバッテリコネクタが提案されている（例えば、特許文献１参照。）。   As an electrical connector having a floating mechanism, for example, a battery connector provided with a contact having two fixing portions fixed to each of two housings and an elastic portion formed between the two fixing portions has been proposed. (For example, refer to Patent Document 1).

また、フローティング機構を有する電気コネクタとして、単一の樹脂製部材からなるハウジングに多数のコンタクトが配列されて装着され、ハウジングの両端側に基板の表面へ固定するコネクタ取付具が装着されてなるコネクタにおいて、コネクタ取付具が、コンタクトの配列方向に横振れ可能なるように屈曲された屈曲部を備えたコネクタが提案されている（例えば、特許文献２参照。）。   In addition, as an electrical connector having a floating mechanism, a connector in which a large number of contacts are arranged and mounted on a housing made of a single resin member, and a connector fixture that is fixed to the surface of the board is mounted on both ends of the housing. In Japanese Patent Application Laid-Open No. H10-260260, a connector has been proposed that includes a bent portion that is bent so that the connector mounting tool can swing in the contact arrangement direction (see, for example, Patent Document 2).

また、半田脚部およびコンタクト間に固定部を設けた雌端子を備えたコネクタが提案されている（例えば、特許文献３参照。）。
欧州特許出願公開第１２７４１５２号明細書 特開平６−２３１８４０号公報 特開平３−１１９９８１号公報 In addition, a connector having a female terminal provided with a fixing portion between a solder leg and a contact has been proposed (for example, see Patent Document 3).
European Patent Application Publication No. 1274152 JP-A-6-231840 Japanese Patent Laid-Open No. 3-119981

特許文献１に提案されたバッテリコネクタによれば、２つの固定部間に形成された弾性部が撓むことにより、上下方向にフローティング可能である。しかしながら、左右方向や前後方向にはフローティングすることができない。また、このバッテリコネクタは、２体のハウジングを用いてフローティング機構を実現しているため、小型化が困難である。また、２つの固定部間に形成された弾性部は、構造上“ばね長”を十分に確保することが困難であり、このバッテリコネクタをフローティングさせるために大きな力を要する。   According to the battery connector proposed in Patent Document 1, the elastic portion formed between the two fixed portions bends and can float in the vertical direction. However, it cannot float in the left-right direction or the front-rear direction. Moreover, since this battery connector implement | achieves the floating mechanism using two housings, size reduction is difficult. In addition, the elastic part formed between the two fixed parts is difficult to secure a sufficient “spring length” in structure, and requires a large force to float the battery connector.

また、特許文献２に提案されたコネクタは、単一の部材からなるハウジングを用いてフローティング機構を実現しているため、２体のハウジングを用いてフローティング機構を実現するものよりも小型化が可能である。また、このコネクタは、コンタクトの配列方向に沿ってはフローティングが容易である。しかしながら、このコネクタは、配列方向に直交する方向にはフローティングが困難である。   Moreover, since the connector proposed in Patent Document 2 realizes a floating mechanism using a housing made of a single member, the connector can be made smaller than the one that realizes a floating mechanism using two housings. It is. Further, this connector can be easily floated along the contact arrangement direction. However, this connector is difficult to float in a direction orthogonal to the arrangement direction.

また、特許文献３に提案されたコネクタは、実質的にフローティング機能を有さない。   Further, the connector proposed in Patent Document 3 has substantially no floating function.

本発明は、上記事情に鑑み、単一の部材からなるハウジングに固定されたコンタクトを左右方向および前後方向にフローティング可能であり、かつフローティングさせるために必要な力を軽減した電気コネクタを提供することを目的とするものである。   In view of the above circumstances, the present invention provides an electrical connector in which a contact fixed to a housing made of a single member can be floated in the left-right direction and the front-rear direction, and the force necessary for floating is reduced. It is intended.

上記目的を達成する本発明の電気コネクタは、

本発明の電気コネクタは、コンタクトの弾性部が「上記半田接続部から上方へ延び上記ハウジング側に折り返して下方へ延びる」ように構成されているため、その弾性部の長さ、即ち“ばね長”を十分に確保することができる。従って、本発明の電気コネクタによれば、単一の部材からなるハウジングに固定されたコンタクトを“ばね長”が十分に確保された弾性部の撓みや捩れによって左右方向および前後方向にフローティング可能であり、かつ電気コネクタをフローティングさせるために必要な力（以下、この力をフローティング力と称する）を軽減することができる。   The electrical connector according to the present invention is configured such that the elastic part of the contact “extends upward from the solder connection part and extends back to the housing side and extends downward”. Therefore, the length of the elastic part, that is, “spring length” ”Can be secured sufficiently. Therefore, according to the electrical connector of the present invention, the contact fixed to the housing made of a single member can be floated in the left-right direction and the front-rear direction by the bending and twisting of the elastic part with sufficient “spring length”. The force required to float the electrical connector (hereinafter, this force is referred to as a floating force) can be reduced.

また、本発明の電気コネクタによれば、コンタクトの接点部が「ハウジングの底面近傍に固定された固定部の他端から上方へ延びる」ように構成されているため、接点部における“ばね長”を十分に確保することができ、変位量が大きな接点部とすることが可能である。   Further, according to the electrical connector of the present invention, since the contact portion of the contact is configured to “extend upward from the other end of the fixed portion fixed in the vicinity of the bottom surface of the housing”, the “spring length” in the contact portion. Can be secured sufficiently, and a contact portion having a large displacement can be obtained.

ここで、本発明の電気コネクタは、上記弾性部が、水平方向に湾曲する湾曲部を有することが好ましい。   Here, in the electrical connector of the present invention, it is preferable that the elastic portion has a curved portion that is curved in the horizontal direction.

このような好ましい形態によれば、弾性部の“ばね長”がより一層長くなり、フローティング力を更に軽減することができる。   According to such a preferred embodiment, the “spring length” of the elastic portion is further increased, and the floating force can be further reduced.

また、本発明の電気コネクタは、一端が回路基板に固定されて上記ハウジングの変位を規制する半田ペグを備えたことも好ましい形態である。   The electrical connector according to the present invention is also preferably provided with a solder peg that is fixed at one end to the circuit board and restricts the displacement of the housing.

このような半田ペグを備えた電気コネクタによれば、ハウジングの変位を所望の範囲内での変位に規制することができる。また、このような半田ペグを備えることにより、電気コネクタの強度向上が図られる。   According to the electrical connector provided with such a solder peg, the displacement of the housing can be restricted to a displacement within a desired range. Moreover, the strength improvement of an electrical connector is achieved by providing such a solder peg.

本発明によれば、単一の部材からなるハウジングに固定されたコンタクトを左右方向および前後方向にフローティング可能であり、かつフローティングさせるために必要な力を軽減した電気コネクタが提供される。   ADVANTAGE OF THE INVENTION According to this invention, the electrical connector which reduced the force required in order to be able to float the contact fixed to the housing which consists of a single member in the left-right direction and the front-back direction, and to make it float is provided.
