Abstract

A movable connector is provided which includes a terminal formed of a single metal piece, the terminal enabling pliability in a movable portion and appropriate contact pressure in a contact portion to be obtained in a compatible way. The terminal of the movable connector includes a plate-thickness-direction conversion portion that interconnects a movable piece and a contact piece, and that reverses a plate thickness direction and a plate width direction of the terminal between the movable piece and the contact piece, and a front elastic arm and a rear elastic arm biasing respectively a front contact point and a rear contact point into pressure contact with the connection target in a direction crossing the plate thickness direction of the contact piece.

First claim

What is claimed is:

1. A movable connector comprising:
a first housing;
a second housing into which a connection target is to be fitted; and
a terminal including a movable piece that supports the second housing in a displaceable way relative to the first housing, and a contact piece having a contact point that is brought into contact with the connection target for conductive connection,
wherein the terminal includes:
a plate-thickness-direction conversion portion that interconnects the movable piece and the contact piece, and that reverses a plate thickness direction and a plate width direction of the terminal between the movable piece and the contact piece; and
an elastic arm that is configured to elastically deform in a direction crossing the plate thickness direction, and configured to press the contact point against the connection object, and
wherein the movable piece is formed so as to be bent in a direction crossing the plate width direction.

2. The movable connector according to claim 1 , wherein the contact piece includes a contact-piece base portion joined to the plate-thickness-direction conversion portion,
the second housing includes a terminal receiving portion that has a bent groove-like shape, and that receives the plate-thickness-direction conversion portion and the contact-piece base portion, and
the contact-piece base portion includes a press-fitting projection that is projected from a plate surface of the contact-piece base portion in the plate thickness direction, and that is press-fitted and fixed to the terminal receiving portion.

3. The movable connector according to claim 2 , wherein the press-fitting projection has a shape projecting from the plate surface of the contact-piece base portion in the plate thickness direction on internal angle side relative to the contact-piece base portion and the plate-thickness-direction conversion portion.

4. The movable connector according to claim 1 , wherein the movable piece includes:
a movable portion; and
a second-housing-side base portion,
wherein the second-housing-side base portion is arranged between the plate-thickness-direction conversion portion and the movable portion, and includes a fixing portion for fixing the movable piece to the second housing.

5. The movable connector according to claim 1 , wherein the second housing includes a fitting connection chamber into which the connection target is inserted along a plane direction of a mounting surface of a substrate to which the first housing is mounted, and
the movable piece has a vertically-vibrating wave shape including:
a plurality of vertical piece portions each extending in a direction crossing an insertion direction of the connection target into the fitting connection chamber; and
a bent portion interconnecting ends of the vertical piece portions adjacent to each other.

6. A terminal comprising:
a movable piece for supporting a housing in a displaceable way relative to another housing;
a contact piece having a contact point for bringing into contact with a connection target for conductive connection;
a plate-thickness-direction conversion portion that interconnects the movable piece and the contact piece, and that reverses a plate thickness direction and a plate width direction of the terminal between the movable piece and the contact piece; and
an elastic arm that is configured to elastically deform in a direction crossing the plate thickness direction, and configured to press the contact point against the connection object, and
wherein the movable piece is formed so as to be bent in a direction crossing the plate width direction.
