Abstract
Abstract An insulated electrical connection block, comprising a housing which encloses interconnected sleeve-shaped contact means, the contact means comprising a pair of abutting conductive sheets formed with respectively opposed radial grooves to define the sleeve-shaped contact means. The housing is formed in two cover-shaped halves which provide recesses adjacent the outer ends of the contact means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A connection block comprising an insulating housing, said housing defining a plurality of apertures around the peripheral edge portions thereof, a plurality of mutually interconnected sleeve-shaped contact means enclosed by said housing and each positioned and adapted to receive a pin-shaped contact element through one of said plurality of apertures in said housing, said plurality of interconnected contact means being integrally formed together by two abutting conductive sheets having respectively opposed grooves to define individual sleeveshaped contact means, said housing comprising two cover-shaped parts, said cover-shaped parts each including pressure means between the inside portion of each of said cover-shaped parts and the adjacent conductive sheet for maintaining said conductive sheets pressed against each other.
Claim 2
Dependent Claim
115 words
A connection block comprising an insulating housing, said housing defining a plurality of apertures around the peripheral edge portions thereof, a plurality of mutually interconnected sleeve-shaped contact means enclosed by said housing and each positioned and adapted to receive a pin-shaped contact element through one of said plurality of apertures in said housing, said plurality of interconnected contact means being integrally formed together by two abutting conductive sheets having respectively opposed grooves to define individual sleeveshaped contact means, said housing comprising two cover-shaped parts, said cover-shaped parts each including pressure means between the inside portion of each of said cover-shaped parts and the adjacent conductive sheet for maintaining said conductive sheets pressed against each other.
Claim 3
Dependent Claim
19 words
A connection block as claimed in claim 1, wherein the conductive sheets abut one another at common plane surfaces.
Claim 4
Dependent Claim
23 words
A connection block as claimed in claim 2, wherein the grooves in said conductive sheets extend radially outwardly from the central portion thereof.
Claim 5
Dependent Claim
27 words
A connection block as claimed in claim 3 wherein the grooves in said conductive sheets extent radially outwardly at equal angular spacings about the central portions thereof.
Claim 6
Dependent Claim
49 words
The connection block as claimed in claim 3 wherein said means for maintaining the conductive sheets pressed together comprise pressure pins formed on the inside portions of said cover-shaped parts, said pressure pins also serving as rotational positioning means for the portions of said conductive sheets forming said grooves.
Claim 7
Dependent Claim
36 words
The connection block as claimed in claim 3 wherein the outer surfaces of said housing are shaped to nest with housings of additional similar connection blocks so as to make said housings stackable with one another.
Claim 8
Dependent Claim
23 words
A connection block as claimed in claim 3 wherein the outer periphery of each of said conductive sheets is round in plan view.
Claim 9
Dependent Claim
28 words
The connection block as claimed in claim 7 wherein the outer edges of said conductive sheets are substantially completely enclosed within said housing to prevent accidental contact therewith.
Claim 10
Dependent Claim
16 words
The connection block as claimed in claim 1 wherein said two conductive sheets are substantially identical.
Claim 11
Dependent Claim
29 words
The connection block as claimed in claim 1 wherein said two conductive sheets with opposed grooves define contact pin sockets substantially independent from the interior shape of said housing.
