Abstract
Abstract A connector apparatus capable of connecting with a complimentary connector for the supply of energy, signals or a commodity has a connector part which can be retracted into the apparatus in response to a control signal to disengage the complimentary connector. The retraction movement may be caused by a piston and cylinder arrangement or by an electromagnet. The connector arrangement has many applications and may be released in response to a variety of circumstances. For example, it may be used in a power supply to a garaged vehicle or grounded aircraft and be arranged to release upon release of the vehicle or aircraft brakes. It may be used in a discharge or filling hose from or to a tanker vehicle and be arranged to release upon starting of the vehicle. It may furthermore be connected in a gas or water supply and be arranged to release in response to a signal from a gas or moisture detector.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
A connector apparatus comprising coaxially arranged and relatively movable first and second connector bodies, said bodies having respective portions arranged to abut each other, said first connector body containing an axially-extending tubular member, said tubular member being axially movable relative to said first connector body, said tubular member having at one end first connection means, said first connection means being arranged to be connected to complementary connection means of the second connector body for the supply of energy, signals or a commodity from one to the other, and said tubular member having an axially-extending internal space for the supply of said energy, signals or commodity to said first connection means, said first connection means being movable between a first position for engagement with said complementary connection means and a second, retracted position for disengagement from said complementary connection means, and further means being provided responsive to a control signal to move said first connection means from said first position to said second position, wherein, during said movement, the abutment of said portions restricts movement of said complementary connection means whereby to effect disconnection, said connection between said first connection means and said complementary connection means constituting the sole interconnection between said first connector body and said second connector body.
Claim 2
Dependent Claim
209 words
A connector apparatus comprising coaxially arranged and relatively movable first and second connector bodies, said bodies having respective portions arranged to abut each other, said first connector body containing an axially-extending tubular member, said tubular member being axially movable relative to said first connector body, said tubular member having at one end first connection means, said first connection means being arranged to be connected to complementary connection means of the second connector body for the supply of energy, signals or a commodity from one to the other, and said tubular member having an axially-extending internal space for the supply of said energy, signals or commodity to said first connection means, said first connection means being movable between a first position for engagement with said complementary connection means and a second, retracted position for disengagement from said complementary connection means, and further means being provided responsive to a control signal to move said first connection means from said first position to said second position, wherein, during said movement, the abutment of said portions restricts movement of said complementary connection means whereby to effect disconnection, said connection between said first connection means and said complementary connection means constituting the sole interconnection between said first connector body and said second connector body.
Claim 3
Dependent Claim
126 words
Apparatus as claimed in claim 1, said first connector body having a radially inwardly facing cylindrical surface and said tubular member having a radially outwardly facing cylindrical surface, said surfaces being radially spaced thereby to define an axially-extending annular chamber, said chamber having an inlet, said control-signal-responsive means comprising means connected to said inlet for applying pressure to said chamber, said cylindrical surface of said tubular member having a circumferential flange, said flange extending radially outwardly as far as said cylindrical surface of said connector body thereby to define a piston, whereby, upon the occurrence of said control signal, pressure is applied to said chamber and said piston by said control-signal-responsive means and said tubular member is moved from said first position to said second position.
Claim 4
Dependent Claim
47 words
Apparatus as claimed in claim 2 further comprising a compression spring located between said first connector body and said tubular member and exerting an axial force on said tubular member in a direction tending to move said tubular member from said second position to said first position.
Claim 5
Dependent Claim
38 words
Apparatus as claimed in claim 2 for connecting a vehicle to a supply, said inlet being connected to a compressed air braking system of said vehicle, whereby disconnection is automatically effected upon operation of said vehicle braking system.
Claim 6
Dependent Claim
61 words
Apparatus as claimed in claim 1, said control-signal-responsive means comprising a cylindrical induction coil mounted on said first connector body and surrounding said tubular member, said tubular member comprising magnetizable material thereby to define an armature, whereby, upon the occurrence of said control signal, a current passes through said coil whereby to exert an axial moving force on said tubular member.
Claim 7
Dependent Claim
38 words
Apparatus as claimed in claim 5 for connecting a vehicle to a supply, said coil being connected to an electrical switching system of said vehicle, whereby disconnection is automatically effected upon operation of said vehicle electrical switching system.
Claim 8
Dependent Claim
41 words
Apparatus as claimed in claim 1, wherein said second connector body is otherwise unsupported, whereby, upon disconnection of said first and second connection means, said second connector body falls away from said first connector body solely under the force of gravity.
Claim 9
Dependent Claim
192 words
A quick release connector arrangement comprising coaxially arranged and relatively movable first and second connector bodies, said first connector body having retractable first connection means, said first connection means being arranged to be connected to complementary connection means of said second connector body for the supply of energy, signals or a commodity from one to the other, said connection between said first connection means and said complementary connection means constituting the sole interconnection of said first and second connector bodies and said second connector body being otherwise unsupported, said first connection means being retractable between a first position for engagement with said complementary connection means and a second, retracted, position for disengagement from said complementary connection means, wherein further means are provided which are responsive to a control signal to move said first connection means from said first position to said second position, and during at least the later stages of said movement there is substantially no relative axial movement between said connector bodies, whereby, after disconnection of said first and said complementary connection means, said second connector body falls away from said first connector body solely under the force of gravity.
Claim 10
Dependent Claim
