Description

本発明は、コネクタに関する。   The present invention relates to a connector.

従来、多数極のコネクタとしては、例えば特許文献１に記載のものなどが知られている。   Conventionally, as a multi-pole connector, for example, the one described in Patent Document 1 is known.

このコネクタにおいて、複数の接触部は、突起部の端面と、突起部の端面から軸心と平行に角柱状に切り欠いた切欠部の底面と、に設けられている。つまり、このコネクタでは複数の接触部が軸心と平行な方向にずれた位置に設けられている。   In this connector, the plurality of contact portions are provided on the end surface of the protruding portion and the bottom surface of the notched portion notched in a prismatic shape parallel to the axis from the end surface of the protruding portion. That is, in this connector, the plurality of contact portions are provided at positions shifted in a direction parallel to the axis.

特開２０１０−１９２１４０号公報JP 2010-192140 A

上述のようなコネクタにおいて、さらに多極化を行うと、図４９に示すように、軸心と平行な方向にコネクタ１のハウジング２が長くなり、これに伴い、相手方のコネクタ５（図５０のコネクタ）のハウジング６も軸心と平行な方向に長くなるため、全体として大型化するという問題があった。なお、図４９中、３は接触部であり、図５０中、７は接触部である。   When the connector as described above is further multipolarized, as shown in FIG. 49, the housing 2 of the connector 1 becomes longer in the direction parallel to the axis, and accordingly, the mating connector 5 (connector of FIG. 50). Since the housing 6 is also elongated in the direction parallel to the shaft center, there is a problem that the overall size of the housing 6 is increased. In FIG. 49, 3 is a contact portion, and in FIG. 50, 7 is a contact portion.

本発明は上記のような事情に基づいて完成されたものであって、小型化した多極のコネクタを提供することを目的とする。   The present invention has been completed based on the above circumstances, and an object thereof is to provide a miniaturized multipolar connector.

上記課題を解決するものとして本発明は、相互に嵌合する第１コネクタと第２コネクタとを備え、前記第１コネクタおよび前記第２コネクタは、接触部を有する複数の端子と、前記端子を保持するハウジングと、を有し、前記第１コネクタの複数の端子は、前記第１コネクタのハウジングにおいて、当該ハウジングの外側と当該ハウジングの内側とに設けた端子保持部によって保持される一方、前記第２コネクタの複数の端子は、前記第２コネクタのハウジングにおいて、前記第１コネクタとの嵌合が完了した際に、前記第１コネクタの端子の接触部と接触するように保持されており、前記端子保持部は、前記第１コネクタのハウジングの軸心と平行な方向にずれた位置に設けられていると共に、前記第１コネクタのハウジングの径方向にずれた位置に設けられており、前記第１コネクタおよび前記第２コネクタは、嵌合の際に回転自在であり、前記第１コネクタの複数の端子の前記接触部はＣ字状をなしており、前記第２コネクタの複数の端子の前記接触部は、Ｃ字状をなしていると共に、それぞれ複数の弾性接触片を備えており、前記第１コネクタの複数の端子の前記接触部と、前記第２コネクタの複数の端子の前記接触部とが、前記弾性接触片を介して接触するコネクタである。 In order to solve the above-described problems, the present invention includes a first connector and a second connector that are fitted to each other, and the first connector and the second connector include a plurality of terminals having contact portions, and the terminals. A plurality of terminals of the first connector, wherein the plurality of terminals of the first connector are held by terminal holding portions provided on an outer side of the housing and an inner side of the housing, The plurality of terminals of the second connector are held in the housing of the second connector so as to come into contact with the contact portions of the terminals of the first connector when the fitting with the first connector is completed, The terminal holding portion is provided at a position shifted in a direction parallel to the axis of the housing of the first connector, and is not aligned with the radial direction of the housing of the first connector. Was provided at a position, the first connector and the second connector is rotatable during mating, the contact portions of the plurality of terminals of said first connector has no C-shaped, The contact portions of the plurality of terminals of the second connector have a C-shape and include a plurality of elastic contact pieces, respectively, and the contact portions of the plurality of terminals of the first connector; The contact portion of the plurality of terminals of the two connectors is a connector that contacts through the elastic contact piece .

本発明において複数の端子は第１コネクタのハウジングにおいてハウジングの外側と内側とにそれぞれ設けた端子保持部によって保持されているので、複数の接触部を軸心と平行な方向にずれた位置に設けたコネクタと比較して、ハウジングが軸心と平行な方向に大型化しない。その結果、本発明によれば、小型化した多極のコネクタを提供することができる。   In the present invention, since the plurality of terminals are held in the first connector housing by the terminal holding portions respectively provided on the outer side and the inner side of the housing, the plurality of contact portions are provided at positions shifted in a direction parallel to the axis. Compared to the connector, the housing does not increase in size in the direction parallel to the axis. As a result, according to the present invention, a miniaturized multipolar connector can be provided.

本発明によれば、嵌合時の方向規制がないので、嵌合操作を円滑に行うことができる。
 According to the present invention, since there is no direction restriction at the time of fitting, the fitting operation can be performed smoothly.

前記第１コネクタおよび前記第２コネクタの少なくとも一方において、複数の端子のうち、最も径方向内側に配される端子がピン端子であってもよい。
このような構成とすると最も内側の端子がピン端子なので、コネクタを、より小型化することができる。 In at least one of the first connector and the second connector, a terminal arranged on the innermost radial direction among the plurality of terminals may be a pin terminal.
With such a configuration, since the innermost terminal is a pin terminal, the connector can be further miniaturized.

本発明によれば、小型化した多極のコネクタを提供することができる。   According to the present invention, a miniaturized multipolar connector can be provided.
