Abstract
Abstract A power source terminal assembly for the wiring of electronic instruments, in which a plurality of terminal screw rods, each having a central flange, are molded into an insulating substrate with the flanges partly embedded therein. At least one of the terminal screw rods is designed so that one side of the flange projects outwardly from the substrate surface by a predetermined amount, and this terminal screw rod is used as a grounding terminal. A casing of an electronic instrument has a hole, for receiving the grounding terminal screw rod to permit one side of its flange to make contact with the casing, and a window for insertion of the other terminal screw rods without making contact with the casing. The power source terminal assembly is engaged with the casing, and the grounding terminal and one portion of the power source assembly are fixedly retained by fixing means to the casing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
A power source terminal assembly, to be mounted in a window of a casing of an electronic instrument, comprising a plurality of terminal screw rods, each said terminal screw rod having a central flange, and an insulating substrate into which said terminal screw rods are molded, with said flanges partly embedded in said substrate, wherein at least a first one of said terminal screw rods is used as a grounding terminal and is formed so that a first side of its flange projects outwardly of the surface of said substrate by a predetermined amount for contacting said casing.
Claim 2
Dependent Claim
98 words
A power source terminal assembly, to be mounted in a window of a casing of an electronic instrument, comprising a plurality of terminal screw rods, each said terminal screw rod having a central flange, and an insulating substrate into which said terminal screw rods are molded, with said flanges partly embedded in said substrate, wherein at least a first one of said terminal screw rods is used as a grounding terminal and is formed so that a first side of its flange projects outwardly of the surface of said substrate by a predetermined amount for contacting said casing.
Claim 3
Dependent Claim
87 words
The assembly of claim 1, said casing having a hole, comprising said first terminal screw rod being inserted into said hole in said casing to permit said first side of its flange to abut against the casing, the other terminal screw rods being located in said window without making contact with said casing, said insulating substrate being engaged with the casing, and fixing means for retaining said first side of said flange of said grounding terminal and one end portion of said insulating substrate to said casing.
Claim 4
Dependent Claim
42 words
The assembly of claim 1, comprising said insulating substrate having a portion with a groove, wherein said portion of said substrate projects through said window, and a portion of an edge of said window in said casing is retained in said groove.
Claim 5
Dependent Claim
42 words
The assembly of claim 2, comprising said insulating substrate having a portion with a groove, wherein said portion of said substrate projects through said window, and a portion of the edge of said window in said casing is retained in said groove.
Claim 6
Dependent Claim
76 words
The assembly of claim 3, said fixing means consisting of said portion with said groove and a nut and washer on one end of said first terminal screw rod used as said grounding terminal, wherein said flanges of all said terminal screw rods except said first terminal screw rod project from the opposite side of said insulating substrate than the side from which said first side of said flange of said first terminal screw rod projects.
Claim 7
Dependent Claim
28 words
The assembly claim 4, said fixing means consisting of said portion with said groove and a nut and washer on one end of said first terminal screw rod.
Claim 8
Dependent Claim
26 words
The assembly of claim 1, said insulating substrate having at least one projection through which project said flanges of all but said first terminal screw rod.
Claim 9
Dependent Claim
26 words
The assembly of claim 5, said insulating substrate having at least one projection through which project said flanges of all but said first terminal screw rod.
Claim 10
Dependent Claim
33 words
The assembly of claim 1, wherein the surface of said insulating substrate in the vicinity of said first side of said flange of said first terminal screw rod does not contact said casing.
Claim 11
Dependent Claim
33 words
The assembly of claim 2, wherein the surface of said insulating substrate in the vicinity of said first side of said flange of said first terminal screw rod does not contact said casing.
Claim 12
Dependent Claim
47 words
The assembly of claim 1, wherein said flanges of all said terminal screw rods except said first terminal screw rod project from the opposite side of said insulating substrate than the side from which said first side of said flange of said first terminal screw rod projects.
