Abstract

The connector includes an inner housing, an outer housing, a locking mechanism for locking, a spring member that pushes back the inner housing during half fitting, and a pushback regulating position that regulates a pushback position. The pushback regulating portion includes a claw portion, a stepped portion against which the claw portion abuts, and a sliding load portion that makes a sliding friction force between the inner housing and the outer housing at a predetermined timing before abutting to be larger than the sliding friction force before the predetermined timing.

First claim

What is claimed is:

1. A connector comprising:
a tubular inner housing configured to hold connecting terminals therein;
a tubular outer housing configured to surround an outer periphery of the inner housing and to be slidable in a fitting direction;
a locking mechanism configured to lock the inner housing with a mating connector at a fitting position;
a spring member configured to bias the inner housing to a rear in the fitting direction to push back the inner housing with respect to the outer housing when a fitting operation is released in a state that the inner housing is in a half fitting position; and
a pushback regulating portion that regulates a position where the inner housing is pushed back to the rear in the fitting direction,
wherein the pushback regulating portion includes:
a claw portion that protrudes from a first sliding surface of one of the inner housing and the outer housing;
a stepped portion that is provided on a second sliding surface of the other of the inner housing and the outer housing and is configured to abut against the claw portion when the inner housing is pushed back; and
a sliding load portion that makes a sliding frictional force between the first sliding surface and the second sliding surface at a predetermined timing before the claw portion and the stepped portion abut against each other to be larger than the sliding frictional force before the predetermined timing; and

wherein the sliding load portion includes:
a first protruding portion provided at a position closer to the stepped portion than the claw portion of the first sliding surface; and
a second protruding portion provided on the second sliding surface to be capable of getting over the first protruding portion.

2. A connector comprising:
a tubular inner housing configured to hold connecting terminals therein;
a tubular outer housing configured to surround an outer periphery of the inner housing and to be slidable in a fitting direction;
a locking mechanism configured to lock the inner housing with a mating connector at a fitting position;
a spring member configured to bias the inner housing to a rear in the fitting direction to push back the inner housing with respect to the outer housing when a fitting operation is released in a state that the inner housing is in a half fitting position; and
a pushback regulating portion that regulates a position where the inner housing is pushed back to the rear in the fitting direction,
wherein the pushback regulating portion includes:
a claw portion that protrudes from a first sliding surface of one of the inner housing and the outer housing;
a stepped portion that is provided on a second sliding surface of the other of the inner housing and the outer housing and is configured to abut against the claw portion when the inner housing is pushed back; and
a sliding load portion that makes a sliding frictional force between the first sliding surface and the second sliding surface at a predetermined timing before the claw portion and the stepped portion abut against each other to be larger than the sliding frictional force before the predetermined timing, and

wherein the sliding load portion includes:
an arm portion configured to elastically press one of the first sliding surface and the second sliding surface toward the other of the first sliding surface and the second sliding surface; and
a third protruding portion provided on the other of the first sliding surface and the second sliding surface in sliding contact with the arm portion.
