CALIBRATION TERMINAL BLOCK Russian patent published in 2016 - IPC H01R9/26 

FIELD: electricity.

SUBSTANCE: invention relates to calibrating terminal block (1), consisting of linear terminal block (2) and calibration plug unit (3) pressed on it. Linear terminal block (2) has several row terminals (4) located next to each other, and has one fixing clamp (5) on both sides of several linear terminals (4). Calibration plug-in unit (3) has several interconnected calibration pins (6). On both sides of several test pins (6) there is one fastening part (7), connected to each other by means of handle (8). Each terminal (4) has two current plates (9), which together form place of separation. Each plug (6) has contact plug (10) configured to be fitted in disconnection place. Both fastening clamps (5) have gripping body (11) with receiving part (12). Both fastening parts (7) have housing (14) with appropriate insert part (15) made with possibility of insertion into receiving part (12). At that, clamping bodies (11) of both fastening clamps (5) have at least two fixing elements (16, 17), and housing (14) of both fasteners (7) have in every case at least two corresponding fixing mating elements (18, 19). Fixing elements (16, 17) and fixing mating elements (18, 19) together set two in-series located in the direction of putting fastening parts (7) positions of fastening parts (7) in fastening clamps (5). In housing (14) of both fasteners (7) is located unblocking element (20), which is set into first and second positions of unlocking.

EFFECT: creation of terminal block to ensure preset contact states when pulling calibration plug unit from linear terminal block and stable specified electric state of individual row line terminals of terminal unit.
