Abstract
Abstract A junction is described facilitating connection and disconnection of a first pneumatic line carrying within it one or more electrical conductors to and from a second pneumatic line carrying within it corresponding conductors by means of a connecting plug insertable therein, the junction having contacts mating with corresponding contacts on the connector, an air passage communicating with the first line and a releasable seal engaging the connector which in turn has not only the contacting surfaces electrically connected to the conductors of the second line but also an air passage communicating with the second line.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
A junction for use in connecting and disconnecting a first pneumatic line carrying within it one or more electrical conductors to and from a second pneumatic line carrying within it corresponding conductors and having a terminal connector operatively connected thereto provided with a protruding portion having a passage communicating with its pneumatic line and electrical contact surfaces connected with its corresponding conductors, comprising a hollow body defining an internal chamber and having a connecting portion at one end adapted for sealing connection to said first line, said portion having a duct establishing communication between said chamber and said first line and accommodating leads from the conductors carried within said line an entrance to said chamber at the other end for receiving the protruding portion of said connector electrical contacts, corresponding in number to the number of electrical conductors carried in said lines, and being adapted for attachment to said leads, resiliently mounted within said chamber and arranged to engage the contact surfaces of said connector when the latter is inserted into said junction, and sealing means for creating a releasable airtight connection between said chamber and the inserted portion of said connector.
Claim 2
Dependent Claim
192 words
A junction for use in connecting and disconnecting a first pneumatic line carrying within it one or more electrical conductors to and from a second pneumatic line carrying within it corresponding conductors and having a terminal connector operatively connected thereto provided with a protruding portion having a passage communicating with its pneumatic line and electrical contact surfaces connected with its corresponding conductors, comprising a hollow body defining an internal chamber and having a connecting portion at one end adapted for sealing connection to said first line, said portion having a duct establishing communication between said chamber and said first line and accommodating leads from the conductors carried within said line an entrance to said chamber at the other end for receiving the protruding portion of said connector electrical contacts, corresponding in number to the number of electrical conductors carried in said lines, and being adapted for attachment to said leads, resiliently mounted within said chamber and arranged to engage the contact surfaces of said connector when the latter is inserted into said junction, and sealing means for creating a releasable airtight connection between said chamber and the inserted portion of said connector.
Claim 3
Dependent Claim
56 words
The junction of claim 1 wherein said sealing means comprises an apertured sealing cap engaging said body and surrounding said entrance, and a resilient seal between said cap and said body, said cap being adapted to compress said seal and for creating a releasable airtight connection between said chamber and the inserted portion of said connector.
Claim 4
Dependent Claim
63 words
The junction of claim 2 wherein said hollow body defines both an internal chamber and outer chambers corresponding in number to the number of said electrical contacts, and each said electrical contact lies within a said outer chamber with a portion of said contact extending into said inner chamber, said contact being biased inwardly, for engaging a corresponding contact surface of the connector.
Claim 5
Dependent Claim
92 words
The combination of the junction of claim 2 with an electric-pneumatic terminal connector operatively connected to said second pneumatic line, and provided with a protruding portion, having a tube communicating with said second pneumatic line and adapted to communicate with said internal chamber of said junction, and a plurality of electrical contact surfaces, connnected with corresponding conductors of said second pneumatic line, positioned sequentially externally of said protruding portion, and separated by insulating elements, each said contact surface and each said insulating element extending entirely around the perimeter of said protruding portion.
Claim 6
Dependent Claim
92 words
The combination of the junction of claim 3 with an electric-pneumatic terminal connector, operatively connected to said second pneumatic line, and provided with a protruding portion, having a tube communicating with said second pneumatic line and adapted to communicate with said internal chamber of said junction, and a plurality of electrical contact surfaces, connected with corresponding conductors of said second pneumatic line, positioned sequentially externally of said protruding portion, and separated by insulating elements, each said contact surface and each said insulating element extending entirely around the perimeter of said protruding portion.
Claim 7
Dependent Claim
185 words
The combination of claim 5 wherein said protruding portion of said connector is generally annular and comprises a forward portion and an after portion of greater outer diameter than said forward portion, said tube lies centrally within said connector and extends axially within both said after and said forward portions, and said connector has two electric contact surfaces spaced axially externally of said after portion, said two contact surfaces being separated by an insulator, each said contact surface and said insulator extending entirely around the circumference of said after portion, said internal chamber of said junction comprises a forward chamber adapted to receive said forward portion of said protruding portion and an after chamber of greater inner diameter than said forward chamber, adapted to receive said after portion of said protruding portion; said junction has two said outer chambers, and two said resilient electrical contacts each lying within a said outer chamber, the said portions of said two contacts that extend into said internal chamber being positioned sequentially along the axis of said after chamber for contact with said two contact surfaces of said connector.
