Description

本発明は、部品間を電気接続するためのコネクタに関し、特に接続位置ズレを吸収可能にしたフローティングコネクタ係る。 The present invention relates to a connector for electrically connecting parts, and particularly to a floating connector capable of absorbing a connection position deviation.

例えば、基板等に電気，電子部品を電気接続する場合に、相互の接続部位に位置ズレが生じると、その接続部位にストレスが加わることになるので、位置ズレを吸収することができる接続構造が必要となる。
図８に従来の位置ズレを吸収するための構造例を示す。
部品１０１と基板１０２をそれぞれ個別に筐体に固定するともに、リード線を用いてはんだ付け１０４を行った場合に、部品１０１と基板１０２と間に位置ズレが生じると、はんだ付け部にストレスが加わり、破断する恐れも生じる。
そこで図８（ａ）では、ビス１０３の取付孔１０２ａを大きくし、位置ズレを解消する例を示す。
しかし、これでは組付けに大きな工数がかかる。
図８（ｂ）は、部品１０１と基板１０２との間をフレキシブルなリード線１０５で接続した構造例を示す。
このようなリード線では、大電流を流すことができない。 For example, when electrical and electronic components are electrically connected to a substrate or the like, if a positional deviation occurs at the mutual connection portion, stress is applied to the connection portion, so that a connection structure capable of absorbing the positional deviation is provided. You will need it.
FIG. 8 shows a structural example for absorbing the conventional misalignment.
When the component 101 and the substrate 102 are individually fixed to the housing and the soldering 104 is performed using the lead wire, if the component 101 and the substrate 102 are misaligned, stress is applied to the soldered portion. In addition, there is a risk of breakage.
Therefore, FIG. 8A shows an example in which the mounting hole 102a of the screw 103 is enlarged to eliminate the positional deviation.
However, this requires a large amount of man-hours for assembly.
FIG. 8B shows an example of a structure in which the component 101 and the substrate 102 are connected by a flexible lead wire 105.
A large current cannot flow through such a lead wire.

特許文献１には、弾性変位するスライダ部を設けたコネクタを開示するが、変位の吸収できる方向に制限があるとともに、大電流を流すのには適していない。 Patent Document 1 discloses a connector provided with a slider portion that elastically displaces, but the direction in which displacement can be absorbed is limited, and it is not suitable for passing a large current.

本発明は、部品間を電気接続する際に、この部品間の位置ズレを吸収するのに効果的で、大電流の接続にも対応可能なフローティングコネクタの提供を目的とする。 An object of the present invention is to provide a floating connector that is effective in absorbing the positional deviation between parts when electrically connecting the parts and can handle a connection of a large current.

本発明に係るフローティングコネクタは、第１部品の第１端子と第２部品の第２端子とを電気接続するためのコネクタであって、略Ｌ字形状の接続ターミナルと、前記接続ターミナルの一方の第１接続端子部と前記第１端子とを相互にフローティング可能に挟持接続するための第１弾性挟持部材と、前記接続ターミナルの他方の第２接続端子部と前記第２端子とを相互にフローティング可能に挟持接続するための第２弾性挟持部材とを有することを特徴とする。 The floating connector according to the present invention is a connector for electrically connecting the first terminal of the first component and the second terminal of the second component, and is one of a substantially L-shaped connection terminal and the connection terminal. The first elastic sandwiching member for sandwiching and connecting the first connection terminal portion and the first terminal so as to be able to float with each other, and the other second connection terminal portion of the connection terminal and the second terminal are mutually floating. It is characterized by having a second elastic holding member for holding and connecting as possible.

ここで、相互にフローティング可能に挟持接続するとは、部品側の端子と接続ターミナル側の端子とを部分的に重ね合せ、弾性挟持部材で挟み込むように接続した状態で、上記端子同士の相対的位置が可動（フローティング）可能になっていることをいう。
これにより、コネクタで２つの部品間を接続する際の位置ズレを吸収することができる。 Here, in a state where the terminals on the component side and the terminals on the connection terminal side are partially overlapped and connected so as to be sandwiched by the elastic sandwiching member, the relative positions of the terminals are relative to each other. Is movable (floating).
As a result, it is possible to absorb the positional deviation when connecting the two parts with the connector.

本発明において、第１弾性挟持部材と前記第２弾性挟持部材のうち、一方の弾性挟持部材はＸ軸方向の位置ズレを許容し、他方の弾性挟持部材はＹ軸方向及びＺ軸方向の位置ズレを許容するのが好ましい。
ここで、Ｘ軸方向，Ｙ軸方向及びＺ軸方向と表現したのは、相対的な可動方向を示したものであり、これにより三次元のいずれの方向に対する位置ズレも相互に解消できる。
また、両方の弾性挟持部材に２軸方向のフローティング機構を付与してもよい。 In the present invention, of the first elastic holding member and the second elastic holding member, one elastic holding member allows a positional deviation in the X-axis direction, and the other elastic holding member is positioned in the Y-axis direction and the Z-axis direction. It is preferable to allow the deviation.
Here, the expressions of the X-axis direction, the Y-axis direction, and the Z-axis direction indicate the relative movable directions, whereby the positional deviation in any of the three-dimensional directions can be mutually eliminated.
Further, both elastic holding members may be provided with a biaxial floating mechanism.

本発明においては、部品側の端子と接続ターミナル側の端子とを部分的に重ね合せるように弾性挟持部材で接続するので、この弾性挟持部材は絶縁性であってもよいが、第１弾性挟持部材又は／及び第２弾性挟持部材が導電性であると、さらに通電性に優れる。 In the present invention, since the terminal on the component side and the terminal on the connection terminal side are connected by an elastic sandwiching member so as to partially overlap each other, the elastic sandwiching member may be insulating, but the first elastic sandwiching member may be provided. When the member and / and the second elastic holding member are conductive, the electrical conductivity is further excellent.

本発明に係るフローティングコネクタにあっては、電気接続する２つの部品側のそれぞれの端子を接続ターミナルの両側にそれぞれフローティング可能に接続できるので、組み付ける部品間での位置ズレを吸収することができる。
また、部品側の端子と接続ターミナル側の端子とを挟持接続するので、大電流の通電が可能であり、温度変化による接続部の位置ズレも吸収可能である。 In the floating connector according to the present invention, since the terminals on the two component sides to be electrically connected can be floatably connected to both sides of the connection terminal, the positional deviation between the components to be assembled can be absorbed.
Further, since the terminal on the component side and the terminal on the connection terminal side are sandwiched and connected, a large current can be energized and the positional deviation of the connecting portion due to a temperature change can be absorbed.

Mutual movement in the Y-axis direction is allowed, and mutual movement in the vertical Z-axis direction is allowed as shown in FIG. 1 (a).

本発明に係るコネクタは、三次元方向に部品間の位置ズレを許容するので、図４に示した第２部品Ｂのように複数の第２端子２を有するものであっても、それぞれの接続部の位置ズレを吸収するので、電気接続性に優れる。 Since the connector according to the present invention allows misalignment between components in the three-dimensional direction, even if the connector has a plurality of second terminals 2 as in the second component B shown in FIG. 4, each connection is made. Since it absorbs the misalignment of the part, it has excellent electrical connectivity.
