Abstract

Claims (30)

1. A connector comprising:

at least one tubular body provided with at least one mouth suitable to be coupled with a complementary connector,

wherein the tubular body is also provided with a series of radial openings which partially house a plurality of spheres arranged along a circumference of the tubular body,

wherein the spheres cooperate with connection means to move in a radial direction of the tubular body between an extended position, in which they protrude towards an outside of the tubular body, and a retracted position, in which they protrude towards an inside of the tubular body,

wherein a thread is formed around the tubular body or around an element integral with the tubular body, wherein the thread is open from a side opposite the mouth of the connector, so that the connector can be screwed into a corresponding threaded seat in a direction facing a side opposite the mouth,

wherein said connection means comprise at least one ring arranged around the tubular body to cooperate with the spheres and be urged axially by at least one spring which acts between the ring and the tubular body,

wherein disconnection means are axially fastened to the ring and can rotate with respect to the ring around its longitudinal axis,

wherein said disconnection means comprise a pusher provided with an annular body joined to a radial protuberance, wherein the annular body is joined to the ring in a rotatable manner around the ring and

wherein the annular body is provided with at least one second protuberance arranged in at least one annular groove of the ring, or vice versa.

2. The connector according to claim 1 , wherein the connector is a female connector with a flat-faced mouth.

3. A connector comprising:

at least one tubular body provided with at least one mouth suitable to be coupled with a complementary connector,

wherein the tubular body is also provided with a series of radial openings which partially house a plurality of spheres arranged along a circumference of the tubular body,

wherein the spheres cooperate with connection means to move in a radial direction of the tubular body between an extended position, in which they protrude towards an outside of the tubular body, and a retracted position, in which they protrude towards the inside of the tubular body,

wherein a thread is formed around the tubular body or around an element integral with the tubular body, wherein the thread is open from a side opposite the mouth of the connector, so that the connector can be screwed into a corresponding threaded seat in a direction facing a side opposite the mouth,

wherein said connection means comprise at least one ring arranged around the tubular body to cooperate with the spheres and be urged axially by at least one spring which acts between the ring and the tubular body,

wherein disconnection means are axially fastened to the ring and can rotate with respect to the ring around its longitudinal axis, and

wherein at least one fitting comprising at least one mouth of the fitting is joined to the tubular body from the side opposite the mouth of the tubular body and has an outer diameter no larger than an external diameter of the thread of the tubular body.

4. A kit comprising a connector and a tool configured to mount and/or remove the connector respectively into and/or from a multi-connector device, the kit comprising:

the connector according to claim 1 ; and

the tool, which comprises:

a head, which is configured to be mechanically coupled with a utensil to impart torque to the tool and which is mechanically connected to a shank, and

a plurality of radial seats defined on an outside of the shank and arranged along a circumference, the plurality of radial seats being configured to partially house said plurality of spheres of the connector, so as to couple the tool with the connector to transmit said torque to the connector.

5. The tool according to claim 4 , wherein the head is mechanically connected to the shank by means of a collar which protrudes radially with respect to the shank.

6. The tool according to claim 4 , wherein at least the shank has an axial cavity.

7. A multi-connector device comprising:

at least one main body provided with at least one coupling side and one or more seats at least partially housing at least one connector according to claim 1 ,

wherein at least one seat of the main body is provided with a thread or an element with a thread, which thread is open towards the coupling side, so that the connector can be inserted from the coupling side into the seat of the main body and screwed into this seat.

8. The multi-connector device according to claim 7 , wherein the mouth of a duct is arranged in the seat for the connector on the side opposite the coupling side for making a hydraulic line with the connector arranged in this seat.

9. The multi-connector device according to claim 7 , wherein at least one seat for disconnection means of the connector is formed in the coupling side of the main body around the seat for the connector.
