Since it is pressed by 24A, when a force is applied from the outside to the electric wire 12 led out from the electric wire insertion chamber 24, the stress generated at the connection portion between the terminal 14 and the electric wire 12 can be suppressed. Thereby, it becomes possible to suppress the damage of the connection part of the terminal 14 and the electric wire 12, simplifying an assembly | attachment process. Further, for example, even when it is difficult to press the plurality of electric wires 12 individually when the connector is downsized, according to the present embodiment, the plurality of electric wires 12 are collected using both surfaces of the pressing member 30. Therefore, the connector can be reduced in size.

また、押圧部材30は、先細状の先細部31と、先細部31の後方に連なり先細部31よりも厚み寸法が大きくされた厚肉部36とを有する。
このようにすれば、先細状の先細部31を第1の電線12Aと第2の電線12Bとの間に差し込むことができるため、押圧部材30の組付けを容易に行うことができる。
The pressing member 30 includes a tapered tapered detail 31 and a thick portion 36 that is connected to the rear of the tapered detail 31 and has a thickness dimension larger than that of the tapered detail 31.
In this way, since the tapered tapered portion 31 can be inserted between the first electric wire 12A and the second electric wire 12B, the pressing member 30 can be easily assembled.

先細部31は、先端部を切り欠いて形成された切欠部34と、切欠部34により弾性変形可能とされ、ハウジング20に係止してハウジング20に対する押圧部材30の離脱を規制する離脱規制部33,33とを備える。
このようにすれば、先細部31の形状を利用してハウジング20に対する押圧部材30の離脱を規制することが可能となる。
The tapered portion 31 includes a cutout portion 34 formed by cutting out the tip portion, and a release regulating portion that is elastically deformable by the cutout portion 34 and that is locked to the housing 20 to restrict the release of the pressing member 30 from the housing 20. 33, 33.
In this way, it is possible to regulate the separation of the pressing member 30 from the housing 20 using the shape of the tapered portion 31.

<他の実施形態>
本明細書に記載された技術は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本明細書に記載された技術の技術的範囲に含まれる。
(1)押圧部材30は、先細部31を備える構成としたが、先細部31を備えない構成としてもよい。例えば、押圧部材30を一定の厚みで形成してもよい。
<Other embodiments>
The technology described in the present specification is not limited to the embodiments described with reference to the above description and the drawings. For example, the following embodiments are also included in the technical scope of the technology described in the present specification.
(1) Although the pressing member 30 is configured to include the tapered portion 31, the pressing member 30 may be configured not to include the tapered portion 31. For example, the pressing member 30 may be formed with a constant thickness.
