## Abstract

The invention relates to an assembly of a T-shaped connector (1) comprising a line input (4), a line output (5) and a measuring socket (2), wherein a measuring device (3), in particular an electrical voltage sensor, is arranged in the measuring socket (2), wherein the measuring device (3) comprises a coupling element (6) for connecting the measuring device (3) to the measuring socket (2), as well as a capacitor assembly with two electrodes (7, 8) located opposite one another, wherein the first electrode (7) is arranged on the coupling element (6) and wherein the second electrode (8) is arranged on an grounding element (9), wherein the measuring socket (2) has a receiving area (10) with a receiving area depth (10′) and wherein the measuring device (3) has an insertion area (11) with an insertion area length (11′), wherein the insertion area depth (10′) is smaller than or equal to the insertion area length (11′), and wherein the second electrode (8) extends into the insertion area (10) of the measuring socket (2).

## Claims

### Claim 1

An assembly of a T-shaped connector (1) comprising a line input (4), a line output (5) and a measuring socket (2), wherein a measuring device (3) comprising an electrical voltage sensor, is arranged in the measuring socket (2), wherein the measuring socket (2) has a receiving area (10) with a receiving area depth (10′),
wherein the measuring device (3) comprises a coupling element (6) for connecting the measuring device (3) to the measuring socket (2), as well as a capacitor assembly with two electrodes (7, 8) facing each other, wherein the first electrode (7) is arranged on the coupling element (6) and wherein the second electrode (8) is arranged on a grounding element (9), and wherein the electrodes (7, 8) comprise rod-shaped or finger-shaped modulating elements (13), and
wherein the measuring device (3) has an insertion area (11) with an insertion area length (11′),
wherein the insertion area (11) extends from the coupling element (6) to a peripheral widening step (18),
wherein the electrodes (7, 8) form an overlapping region (17) which also extends to the widening step (18),
wherein the receiving area depth (10′) is smaller than or equal to the insertion area length (11′) of the measuring device (3), and
wherein the second electrode (8) of the measuring device (3) extends into the receiving area (10) of the measuring socket (2).

### Claim 2 (depends on 1)

The assembly according to claim 1, wherein the outer surfaces of the receiving area (10) and of the insertion area (11) are designed to be substantially opposite, so that when the measuring device (3) is inserted into the measuring socket (2), the insertion area (11) rests flush against the receiving area (10) without forming any gaps.

### Claim 3 (depends on 2)

The assembly according to claim 2, wherein the receiving area (10) and the insertion area (11) are frustoconically shaped.
