## Abstract

A connector which is provided with connector terminals which include a plurality of terminals that are configured to be in contact with a connection target and achieves reliable contact with the connection target while preventing the plurality of terminals from being in contact with each other when the plurality of terminals come into contact with the connection target and are displaced by the connection target is provided. A connector includes a housing and a connector terminal, and the connector terminal includes a front terminal including a contact portion that comes into contact with a plug connector inserted from an insertion port of the housing and an elastic arm that supports the contact portion in a displaceable manner; and a rear terminal including a contact portion that comes into contact with the plug connector subsequent to the contact portion of the front terminal and an elastic arm.

## Claims

### Claim 1

A electric connector comprising:
a housing and a connector terminal, the connector terminal including:
a front terminal including a contact portion that comes into contact with a connection target inserted from an insertion port of the housing and an elastic piece that supports the contact portion in a displaceable manner; and
a rear terminal including a contact portion that comes into contact with the connection target subsequent to the contact portion of the front terminal and an elastic piece that supports the contact portion of the rear terminal in a displaceable manner; and
a proximal end supporting and directly connected to both the front terminal and the rear terminal, the proximal end being fixed to the housing,
wherein the connector terminal is a plate-shaped punched terminal formed by a plate-shaped conductive metal,
wherein the elastic piece of the front terminal and the elastic piece of the rear terminal extends directly from an edge portion of the proximal end,
wherein the rear terminal includes a contact that is disposed on the contact portion and comes into contact with the connection target inserted from the insertion port, and the elastic piece has a displacement fulcrum which is located at a position closer to the connection target inserted in the housing than to the contact is, and
wherein the contact of the rear terminal is a portion of an edge of the plate-shaped conductive metal from a contact position that is initially in contact with the connection target inserted from the insertion port to a contact position that is in contact with the connection target at a regular mating position.

### Claim 2 (depends on 1)

The electric connector according to claim 1, wherein the front terminal includes a contact that comes into contact with the connection target inserted from the insertion port, and the contact is located at a position closer to the connection target inserted in the housing than the displacement fulcrum of the elastic piece of the front terminal is.

### Claim 3 (depends on 1)

The electric connector according to claim 1, wherein the front terminal includes a gap between the contact portion and the elastic piece so as to house an end of the contact portion of the rear terminal which faces the insertion port.

### Claim 4 (depends on 2)

The electric connector according to claim 2, wherein the contact of the front terminal is a portion of an edge from a contact position that is initially in contact with the connection target inserted from the insertion port to a contact position that is in contact with the connection target at a regular mating position.

### Claim 5 (depends on 2)

The electric connector according to claim 2, wherein the contact of the front terminal and the contact of the rear terminal are displaced in different directions without being in contact with each other while the contact of the front terminal and the contact of the rear terminal are in contact with the connection target.

### Claim 6 (depends on 1)

The electric connector according to claim 1, wherein the proximal end is provided between the front terminal and the rear terminal.
