## Abstract

A connection device includes an adapter that covers a connection target that is connected to a connector, where the adapter is secured to a connection apparatus that is provided with the connection target. The connection device includes a housing that has a cylindrical portion that holds the connector such that the connector is movable relative to the cylindrical portion in an axial direction, where the cylindrical portion is engaged with the adapter such that the connector is connected to the connection target, and a first spring that urges the connector toward the connection target.

## Claims

### Claim 1

A connection device, comprising:
an adapter that covers a connection target to which a connector is to be connected, the adapter being secured to a connection apparatus that is provided with the connection target; and
a housing that includes:
a cylindrical portion that holds the connector such that the connector is movable relative to the adapter in an axial direction, the cylindrical portion being engaged with the adapter such that the connector is connected with the connection target, and
a first spring that urges the connector toward the connection target.

### Claim 2 (depends on 1)

The connection device according to claim 1, wherein the housing is provided with an outer cylindrical portion that is rotatable relative to the adapter about the axial direction, and
wherein the outer cylindrical portion and the adapter are lockable with each other, the outer cylindrical portion and the adapter have respective engagement portions in which a lock position of the outer cylindrical portion with the adapter in the axial direction changes in accordance with a position of the outer cylindrical portion relative to the adapter in the axial direction and in a direction of rotation about the axial direction.

### Claim 3 (depends on 2)

The connection device according to claim 2, wherein one of the engagement portions of the outer cylindrical portion and the adapter is a protrusion portion, and the other one of the engagement portions of the outer cylindrical portion and the adapter is a groove portion, and
the groove portion is engageable with the protrusion portion and extending so as to form a stepped shape.

### Claim 4 (depends on 1)

The connection device according to claim 1, wherein the adapter and the cylindrical portion have respective guide portions that determine an engagement position at which the adapter and the cylindrical portion are engageable with each other.

### Claim 5 (depends on 1)

The connection device according to claim 1, wherein the connector is provided with a ferrule and a second spring that urges the ferrule toward a connecting end in the axial direction.

### Claim 6 (depends on 5)

The connection device according to claim 5, wherein, when the connector is connected with the connection target, the connector moves against urging force of the first spring after the ferrule has moved against urging force of the second spring.

### Claim 7 (depends on 1)

The connection device according to claim 1, wherein the cylindrical portion has an engagement portion at a connecting end portion, and
the connector is formed to be movable relative to a support portion of the engagement portion of the cylindrical portion in the axial direction.

### Claim 8

A method for the manufacture of a connection device, comprising:
forming an adapter covering a connection target to which a connector is to be connected, the adapter being secured to a connection apparatus that is provided with the connection target; and
forming a housing including:
forming a cylindrical portion that holds the connector in a moveable manner relative to the adapter in an axial direction, the cylindrical portion being engaged with the adapter to cause the connector to be connected with the connection target; and
forming a spring that urges the connector toward the connection target.
