Abstract

A charging inlet includes a rear holder installed to a housing and supporting electric wires connected to the terminals accommodated in the terminal accommodating chambers. The rear holder includes an inner rear holder and an outer rear holder. In an outer peripheral portion of the inner rear holder, a plurality of outer electric wire insertion portions each having an inner electric wire support surface is provided. In an inner peripheral portion of the outer rear holder, a plurality of inner electric wire insertion portions each having an outer electric wire support surface. The plurality of inner electric wire insertion portions communicates with an outer peripheral side of the outer rear holder through a communication portion. The electric wires are sandwiched between the inner electric wire support surfaces and the outer electric wire support surfaces.

First claim

What is claimed is:

1 . A connector comprising:
a housing having a plurality of terminal accommodating chambers into which terminals are inserted; and a rear holder installed to the housing and supporting electric wires connected to the terminals accommodated in the respective plurality of terminal accommodating chambers, wherein the rear holder includes an inner rear holder and an outer rear holder fitted to an outer peripheral side of the inner rear holder, the inner rear holder is provided with, on an outer peripheral portion, a plurality of outer electric wire insertion portions each having an inner electric wire support surface that has a semicircular cross section facing outward, the outer rear holder is provided with, on an inner peripheral portion, a plurality of inner electric wire insertion portions each having an outer electric wire support surface that corresponds to the inner electric wire support surface and has a semicircular cross section facing inward, the plurality of inner electric wire insertion portions communicates with an outer peripheral side of the outer rear holder through a communication portion, and the electric wires are sandwiched between the inner electric wire support surfaces and the outer electric wire support surfaces.

2 . The connector according to claim 1 , wherein
each of the inner rear holder and the outer rear holder includes a terminal holding portion that restricts rearward movement of each of the terminals inserted into the terminal accommodating chambers.

3 . The connector according to claim 1 , wherein
a locking mechanism that maintains a fitted state is provided between the inner rear holder and the outer rear holder.
