Description

シールドコネクタShield connector
　本明細書によって開示される技術は、シールドコネクタに関する。 The technology disclosed in this specification relates to a shield connector.
　従来、電気自動車やハイブリッド車に搭載されたモータ、インバータ等の機器に電線を接続するためのコネクタとして、電線の端末部を保持するハウジングを有し、機器を収容するシールドケースに固定されるシールドコネクタがある。このようなシールドコネクタとして、一対のブラケットを備えるコネクタが知られている（特許文献１参照）。一対のブラケットのそれぞれは、板状の圧着片を備えており、この圧着片には、シート状のシールド導体が圧着されている。一対のブラケットが対向状態で配置され、ハウジングに固定されることで、一対のシールド導体が筒状に構成されている。ハウジングから導出された電線は筒状のシールド導体の内側に配置されている。一対のブラケットは、ボルト挿通孔を有しており、ボルトをこのボルト挿通孔に挿通して機器ケースにねじ付けることにより、ブラケットがハウジングと共に機器ケースに固定される。 Conventionally, as a connector for connecting an electric wire to a device such as a motor or an inverter mounted on an electric vehicle or a hybrid vehicle, a shield having a housing that holds a terminal portion of the electric wire and fixed to a shield case that accommodates the device There is a connector. As such a shielded connector, a connector including a pair of brackets is known (see Patent Document 1). Each of the pair of brackets includes a plate-shaped crimping piece, and a sheet-shaped shield conductor is crimped to the crimping piece. The pair of shield conductors are arranged in a facing state and fixed to the housing, whereby the pair of shield conductors are configured in a cylindrical shape. The electric wire led out from the housing is arranged inside the cylindrical shield conductor. The pair of brackets have a bolt insertion hole, and the bracket is fixed to the device case together with the housing by inserting the bolt into the bolt insertion hole and screwing the bolt into the device case.

　上記のような構成では、シールドコネクタの機器ケースへの取り付け作業の際などにおいて、ブラケットがハウジングに対して不用意に回転し、ブラケットとシールド導体とが、ハウジングに対する正規の固定位置からずれてしまうおそれがあった。 In the above configuration, the bracket is inadvertently rotated with respect to the housing, for example, when the shield connector is attached to the device case, and the bracket and the shield conductor are displaced from the normal fixed position with respect to the housing. There was a fear.
　本明細書によって開示されるシールドコネクタは、コネクタハウジングと、前記コネクタハウジングから外部に延びる電線と、前記電線をシールドするシールド導体と、前記シールド導体を保持して前記コネクタハウジングに組み付けられたシールド組付部材とを備えるシールドコネクタであって、前記シールド組付部材および前記コネクタハウジングのうち一方が回り止め片を備え、他方が、前記回り止め片に沿って配置された回り止め壁を備える。 A shield connector disclosed in the present specification includes a connector housing, an electric wire extending from the connector housing to the outside, a shield conductor that shields the electric wire, and a shield assembly that is attached to the connector housing while holding the shield conductor. A shield connector including an attachment member, wherein one of the shield assembly member and the connector housing includes a detent piece, and the other includes a detent wall disposed along the detent piece.
　上記の構成によれば、シールド組付部材がコネクタハウジングに対して回転しようとすると、回り止め壁が回り止め片に干渉し、シールド組付部材のそれ以上の回転を規制する。これにより、シールド組付部材がハウジングに対して不用意に回転することを抑制できる。 According to the above configuration, when the shield assembly member tries to rotate with respect to the connector housing, the rotation prevention wall interferes with the rotation prevention piece and restricts further rotation of the shield assembly member. Thereby, it can suppress that a shield assembly member rotates carelessly with respect to a housing.
　上記のシールドコネクタにおいて、前記シールド組付部材が、前記コネクタハウジングに対して一方向から配置されている導体保持部を有し、前記シールド導体が前記導体保持部に保持されて前記電線を前記一方向から覆っていてもよい。 In the above shield connector, the shield assembly member has a conductor holding portion disposed from one direction with respect to the connector housing, and the shield conductor is held by the conductor holding portion so that the one electric wire is connected to the one side. You may cover from the direction.
　ここで、従来のように、シールド導体が筒状となっている場合には、シールド組付部材が回転したとしても電線が筒状のシールド導体から外れてしまうという事態は起こりにくい。しかし、シールド導体が電線を一方向から覆っている場合には、シールド組付部材が回転し、電線に対するシールド導体の位置がずれてしまうと、シールド機能を十分に発揮できなくなるおそれがある。このような構成のシールドコネクタにおいて、回り止め片と回り止め壁によってシールド組付部材の不用意な回転を抑制する構成を採用することが、シールド機能の確保のために効果的である。 Here, when the shield conductor has a cylindrical shape as in the prior art, even if the shield assembly member rotates, it is unlikely that the electric wire will be detached from the cylindrical shield conductor. However, when the shield conductor covers the electric wire from one direction, if the shield assembly member rotates and the position of the shield conductor with respect to the electric wire shifts, the shield function may not be sufficiently exhibited. In the shield connector having such a configuration, it is effective to secure a shield function by adopting a configuration that suppresses inadvertent rotation of the shield assembly member by the anti-rotation piece and the anti-rotation wall.

　シールドコネクタ１の機器ケースへの取り付けの際には、メインブラケット５０の２つのボルト挿通孔６７、７７のそれぞれにボルトを挿通し、これらのボルトを機器ケースにねじ付ける。これにより、シールドブラケット４０がハウジング２０と共に機器ケースに固定される。 When attaching the shield connector 1 to the device case, the bolts are inserted into the two bolt insertion holes 67 and 77 of the main bracket 50, and these bolts are screwed to the device case. Thereby, the shield bracket 40 is fixed to the device case together with the housing 20.
［作用効果］
　上記のように本実施形態によれば、シールドコネクタ１は、ハウジング２０と、ハウジング２０から外部に延びる電線１１と、電線１１をシールドするシールド導体３０と、シールド導体３０を保持してハウジング２０に組み付けられたシールドブラケット４０とを備える。そして、シールドブラケット４０が抜け止め片５４を備え、ハウジング２０が、抜け止め片５４に沿って配置された規制内壁２８Ａと中間壁２９とを有している。 [Function and effect]
As described above, according to the present embodiment, the shield connector 1 includes the housing 20, the electric wire 11 extending from the housing 20 to the outside, the shield conductor 30 that shields the electric wire 11, the shield conductor 30, and the housing 20. The shield bracket 40 is assembled. The shield bracket 40 includes a retaining piece 54, and the housing 20 includes a regulation inner wall 28 </ b> A and an intermediate wall 29 disposed along the retaining piece 54.
　ここで、シールドコネクタ１の機器ケースへの取り付け作業の際などにおいて、例えばボルトの機器ケースへのねじ付けに伴って、シールドブラケット４０がボルトの回転と共に回転してしまうことがある。本実施形態のシールドコネクタ１の構成によれば、シールドブラケット４０が回転しようとすると、規制内壁２８Ａおよび中間壁２９のうち一方または双方が抜け止め片５４に干渉する。これによりシールドブラケット４０のそれ以上の回転が規制される。 Here, when attaching the shield connector 1 to the device case, the shield bracket 40 may be rotated with the rotation of the bolt, for example, when the bolt is screwed to the device case. According to the configuration of the shield connector 1 of the present embodiment, when the shield bracket 40 tries to rotate, one or both of the regulation inner wall 28A and the intermediate wall 29 interfere with the retaining piece 54. Thereby, the further rotation of the shield bracket 40 is controlled.
　また、シールドブラケット４０が、ハウジング２０に対して一方向から配置されている導体保持部５１を有し、シールド導体３０が導体保持部５１に保持されて電線１１を一方向から覆っている。 Further, the shield bracket 40 has a conductor holding portion 51 arranged from one direction with respect to the housing 20, and the shield conductor 30 is held by the conductor holding portion 51 and covers the electric wire 11 from one direction.
　ここで、従来のように、シールド導体が筒状となっている場合には、ブラケットが回転したとしても、電線が筒状のシールド導体から外れてしまうという事態は起こりにくい。これに対し、本実施形態のように、シールド導体３０が電線１１を一方向から覆っている場合には、シールドブラケット４０が回転し、シールド導体３０の電線１１に対する位置がずれてしまうと、電線１１に対するシールド機能が十分に発揮できなくなるおそれがある。このような構成のシールドコネクタ１において、抜け止め片５４と規制内壁２８Ａおよび中間壁２９とによってシールドブラケット４０の不用意な回転を抑制する構成を採用することが、シールド機能の確保のために効果的である。 Here, in the case where the shield conductor has a cylindrical shape as in the prior art, even if the bracket rotates, it is unlikely that the electric wire will be disconnected from the cylindrical shield conductor. On the other hand, when the shield conductor 30 covers the electric wire 11 from one direction as in this embodiment, the shield bracket 40 rotates and the position of the shield conductor 30 with respect to the electric wire 11 is shifted. There is a possibility that the shield function against 11 cannot be sufficiently exhibited. In the shield connector 1 having such a configuration, it is effective to secure the shielding function by adopting a configuration in which the retaining bracket 54, the regulation inner wall 28A, and the intermediate wall 29 are used to suppress the inadvertent rotation of the shield bracket 40. Is.
