Abstract
Abstract The subject matter of the invention is a connector block (1) with solderless, non-screwed and stripping-free terminal elements (2, 3) having a polytropic air gap, for terminating dropwire cables (6) and cable wires (7). The terminal elements (2, 3), which comprise a terminal contact (2b, 3b) and a center contact (2a, 3a), have a semi-circular extension (2a') on the underside (2') of the center contact (2a, 3a), the spacing of said semi-circular extension relative to an earth bar (4) mounted in the housing lower half (12) being variable by tilting the earth bar (4) about 180°; said earth bar (4) is adapted to be mounted at either of two different levels. Thereby it is possible to select a high-voltage spark-gap function.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
174 words
A connector block with solderless, non-screwed and stripping-free terminals having a polytropic air gap for terminating communication cables, comprising a housing upper half and a housing lower half, characterized in that the connector block (1) receives angular pairs of terminal elements (2, 3) respectively rotated about 180° in separate receptacles (13) of the housing upper half (11) and the housing lower half (11) in plugged-in relationship, that each of said terminal elements (2, 3) in addition to a terminal contact (2b, 3b) includes a centre contact (2a, 3a) with a semi-circular extension (2a') integrally formed therewith on the underside (2') thereof, that centrally of the longitudinal axis of the connector block (1) within the housing lower half (11) a groove (12a) is formed including plural receptacles (12b, 12c) formed with two different stepped shoulders (12b', 12c'), that an earth bar (4) rotatable about 180° is adapted to be inserted into said groove (12a) at two different levels, and that the earth bar (4) is formed with tabs (4a) engaging in said receptacles (12b, 12c).
Claim 2
Dependent Claim
174 words
A connector block with solderless, non-screwed and stripping-free terminals having a polytropic air gap for terminating communication cables, comprising a housing upper half and a housing lower half, characterized in that the connector block (1) receives angular pairs of terminal elements (2, 3) respectively rotated about 180° in separate receptacles (13) of the housing upper half (11) and the housing lower half (11) in plugged-in relationship, that each of said terminal elements (2, 3) in addition to a terminal contact (2b, 3b) includes a centre contact (2a, 3a) with a semi-circular extension (2a') integrally formed therewith on the underside (2') thereof, that centrally of the longitudinal axis of the connector block (1) within the housing lower half (11) a groove (12a) is formed including plural receptacles (12b, 12c) formed with two different stepped shoulders (12b', 12c'), that an earth bar (4) rotatable about 180° is adapted to be inserted into said groove (12a) at two different levels, and that the earth bar (4) is formed with tabs (4a) engaging in said receptacles (12b, 12c).
Claim 3
Dependent Claim

Claim 4
Dependent Claim
42 words
A connector block as claimed in claim 1, characterized in that the terminal contact (2b) of the one terminal element (2) of said pair and the centre contact (3a) of the other terminal element (3) have the same arm length (FIG. 5).
Claim 5
Dependent Claim
41 words
A connector block as claimed in claim 1, characterized in that on either side of the terminal contact (2b, 3b) centrally extending pairs of clamping ribs (11a, 11b) are provided on the housing upper half (11) of the connector block (1).
Claim 6
Dependent Claim
20 words
A connector block as claimed in claim 1, characterized in that limiting slots (11h) are provided on the receptacles (13).
Claim 7
Dependent Claim
