Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
A device for facilitating the testing of experimental circuits comprising a circuit board, a plurality of printed bus bars on said board fitted with sockets into which connecting wires can be plugged, a plurality of integrated circuit receiving stations disposed among the bus bars, said stations being electrically isolated from each other and from said bus bars, each of said stations comprising a set of sockets into which connecting wires can be plugged, and means for removably mounting an integrated circuit with its terminals electrically connected to respective sockets, some of said stations being formed on individual carriers removably secured to said circuit board.
Claim 2
Independent Claim
104 words
A device for facilitating the testing of experimental circuits comprising a circuit board, a plurality of printed bus bars on said board fitted with sockets into which connecting wires can be plugged, a plurality of integrated circuit receiving stations disposed among the bus bars, said stations being electrically isolated from each other and from said bus bars, each of said stations comprising a set of sockets into which connecting wires can be plugged, and means for removably mounting an integrated circuit with its terminals electrically connected to respective sockets, some of said stations being formed on individual carriers removably secured to said circuit board.
Claim 3
Dependent Claim
38 words
A device as claimed in claim 1, wherein the sockets of the receiving stations, or some of them, are in the form of multiple connection devices adapted to make electrical connections to a plurality of the electric leads.
Claim 4
Dependent Claim
21 words
A device as claimed in claim 2, including further said multiple connection devices independently distributed among the bus bars and stations.
Claim 5
Dependent Claim
98 words
A device as claimed in claim 1, wherein each carrier is a plate and the means for mounting an integrated circuit at the station comprises a plurality of apertures arranged in the plate so that the terminals of an integrated circuit can project therethrough, a spring connector mounted adjacent each aperture on the side of the board opposite to that on which the integrated circuit is to be mounted and an insulating support member fixed to the plate adjacent the spring connectors, said spring connectors being arranged to grip said terminals by pressing them against the support member.
Claim 6
Dependent Claim
71 words
A device as claimed in claim 4, wherein each spring connector comprises a leg portion which extends perpendicularly to the plate in a position to be contacted by an integrated circuit terminal (when mounted), and a support portion which extends from the end of the leg portion remote from the plate and has its end fixed to the plate and electrically connected to a said socket of the corresponding receiving station.
Claim 7
Dependent Claim
34 words
A device as claimed in claim 5, wherein the end of said leg portion is connected to an additional portion which extends substantially parallel to the plate and away from the insulating support member.
Claim 8
Dependent Claim
50 words
A device as claimed in claim 6, wherein the spring is rounded at the corner between said additional portion and said leg portion and wherein the adjacent part of the support member is chamfered to facilitate insertion of an integrated circuit terminal between the spring connector and the support member.
Claim 9
Dependent Claim
30 words
A device as claimed in claim 5, wherein said end of the support portion of the spring connector is electrically connected by a printed conducting strip to its associated socket.
Claim 10
Dependent Claim
40 words
A device as claimed in claim 1, wherein the said stations are arranged in rows, the bus bars extending from an electric plug at one side of the board to an electric socket at the opposite side of the board.
