Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
271 words
A connecting device for telecommunication circuits, to allow the transfer of signals from input terminals receiving the signals to be processed to output terminals carrying the processed signals, the said transfer being through circuits suitable to carry out said processing, said connecting device comprising: a three-sided frame made of insulating material and shaped as a rectangle open in correspondence of one of the minor sides thereof; input and respectively output terminals on one outwardly directed face of two opposite sides of said three-sided frame, said terminals having an end portion thereof embedded in the material of said sides and ending on the inner face thereof; guiding grooves on the said inner face of the opposite sides of said three-sided frame; a movable board, having edges engaging said grooves and having shape and size such as to be coincident with the shape and size of the frame concavity; printed circuits on the faces of said board, for connecting electrical components for processing said input signals; input and output connectors connected to said input and output terminals respectively; conjugate connectors carried by said board and cooperating with said input and output connectors and electrically connected to the circuits of said board, in order to connect the said input terminals with the said output terminals through the said processing circuits; said two opposite sides of said frame are connected by a fixed board provided with a connector and with printed leads which have one end connected to contacts in the connector and the other end connected to the input or respectively output terminals, the said fixed board being parallel to the said movable board.
Claim 2
Dependent Claim
271 words
A connecting device for telecommunication circuits, to allow the transfer of signals from input terminals receiving the signals to be processed to output terminals carrying the processed signals, the said transfer being through circuits suitable to carry out said processing, said connecting device comprising: a three-sided frame made of insulating material and shaped as a rectangle open in correspondence of one of the minor sides thereof; input and respectively output terminals on one outwardly directed face of two opposite sides of said three-sided frame, said terminals having an end portion thereof embedded in the material of said sides and ending on the inner face thereof; guiding grooves on the said inner face of the opposite sides of said three-sided frame; a movable board, having edges engaging said grooves and having shape and size such as to be coincident with the shape and size of the frame concavity; printed circuits on the faces of said board, for connecting electrical components for processing said input signals; input and output connectors connected to said input and output terminals respectively; conjugate connectors carried by said board and cooperating with said input and output connectors and electrically connected to the circuits of said board, in order to connect the said input terminals with the said output terminals through the said processing circuits; said two opposite sides of said frame are connected by a fixed board provided with a connector and with printed leads which have one end connected to contacts in the connector and the other end connected to the input or respectively output terminals, the said fixed board being parallel to the said movable board.
Claim 3
Dependent Claim
33 words
A device according to claim 1, wherein the connector of the said fixed board is located in front of the opening of the said frame and is perpendicular to the opposite sides thereof.
Claim 4
Dependent Claim
18 words
A device according to claim 2, wherein the said connector forms the third side of the said frame.
Claim 5
Dependent Claim
81 words
A device according to claim 1, wherein the said input and output terminals have, on the inner face of the said opposite frame sides, areas of conductive material; and wherein the movable board is provided on one edge parallel to the said frame sides with contact springs connected to the board circuits and having the same distance as the areas of conductive materials existing on the frame, said areas and springs forming the conjugate contacts in the frame and the board.
Claim 6
Dependent Claim
19 words
A device according to claim 1, further comprising coupling means allowing its coupling with a plurality of identical devices.
Claim 7
Dependent Claim
35 words
A device according to claim 5, wherein in that the said means comprises through-holes perpendicular to the faces of the device and located in the major sides of the frame, and rods engaging said holes.
