Definitions

  • the present invention relates to a disconnect terminal with a switching status display.
  • Such isolating terminals are used in different applications.
  • DE 44 44 551 A1 describes a current transformer disconnect terminal with a contact piece in the form of an angle-adjustable contact disk, which uses a contact lag distance to ensure that the secondary side of a connected current transformer can never be open when the current passage through the terminal is disconnected or closed.
  • the angle of the contact disk can be adjusted by means of a pivoting lever about an axis of rotation.
  • the actuation of the current transformer disconnect terminal ie the manual pivoting of the swivel lever from one switching position to the other in the case of several immediately adjacent disconnect terminals en bloc, can be carried out by inserting a coupling pin into the knobs of the swivel lever of the immediately adjacent disconnect terminals.
  • DE 44 44 556 A1 refers to switchable terminal blocks with an insulating material switch lever handle.
  • the grip is provided with two visible surfaces, one of which alternately faces the direction of view of the operator in each of the two switch positions of the shift lever and the other seat surface faces away from the operator's line of sight in the same switch position.
  • the handles of immediately adjacent terminal blocks can be coupled using a transparent cap that overlaps two or more handles.
  • DE 10 2008 014 176 B4 describes a terminal block and also a longitudinal disconnector with a disconnecting blade for pivotable arrangement in a terminal housing of the terminal block, with a terminal housing, with a busbar consisting of two sections and two conductor connection elements for connecting one conductor to a section of the busbar being arranged in the terminal housing, with the two sections are connected to one another in a first position of the separating knife and separated from one another in a second position of the separating knife.
  • the separating blade is partially surrounded by an insulating housing.
  • the sectionalizing switch can be actuated not only with the aid of a screwdriver, which is inserted into an actuation shaft of the insulating housing for this purpose, but also with the aid of a switch connection which has two legs and a handle section connecting the legs. This means that two longitudinal disconnectors of two terminal blocks arranged next to one another can be operated at the same time are actuated, for which purpose one leg is inserted into the actuation shaft of a sectionalizing switch.
  • a disconnect terminal comprises at least one switching lever, the switching lever being adjustable independently of another switching lever from a first switching position into at least one second switching position and back.
  • the disconnect terminal has a switching status display with a movable display section and a stationary display section, with the switching status display showing the respective switch position or at least one other switch position of the switching lever, with these two display sections being combined in the first switch position in such a way that a "closed" symbolism is unambiguous is visibly recognizable, and in the second switching position, this symbolism is separated, from which a separation is clearly recognizable.
  • switching status display can also be used for other terminal types that have coupling elements, for example.
  • a further embodiment provides that at least the first switching position is indicated by a cover and/or a display of a partial display section and at least the second switch position is indicated by a display and/or a covering of a partial display section. This results in a compact structure.
  • the switching status display advantageously supports recognisability through coloring, symbols and/or geometry.

  • the switching device connects the two connection sections and thus the first conductor rail 3a and the second conductor rail 4a in an electrically conductive manner, so that the first clamping section is electrically conductively connected to the second clamping section.
  • the upper area of the shift lever 6 rests with an actuating section 7 on a stop section 9 of the housing 2, as in FIG 1 for the front disconnect terminal 1 is shown.
  • the two connecting sections are separated and insulated from one another, i.e. the electrically conductive connection of the two connecting sections and thus the conductor rails 3a and 4a is canceled or separated, with the conductor rail 3'a still being here is electrically connected to the shift lever 6'.
  • a receptacle 8 8' is formed in the actuating section 7, 7' from above in the radial direction in relation to the pivot axis 5a.

In this way, the locking lugs 16 also form a captive function of the coupling element 11.

  • the switching or adjustment or movement direction of the coupling element 11 is in a straight line in the radial direction in relation to the pivot axis 5a.
  • the switching/adjustment/movement direction can also run rotationally or in a different trajectory. However, this takes place in a different direction than the direction in which the actuating movement of the shift lever 6, 6' runs around the pivot axis 5a, e.g. also conceivable along a different trajectory.

In this way, the shift levers 6, 6' can be selectively switched to one another.
  • the coupling element 11 has a switching pin 12 and two or more drivers 13 .
  • This driver 13 can be arranged on one side to the right or left of the switch pin 12 or on both sides evenly or unevenly distributed.
  • the switching levers 6, 6' of, for example, three or four or more isolating terminals 1, 1' can also be connected.
  • a not shown, but conceivable variant of the coupling element 11 is that the coupling element 11 has two pins of equal length, which are inserted into the receptacles of the adjacent shift lever 6, 6 'and the handle 14 has a separation (e.g. in the middle) that in the connected state the shift lever 6, 6', ie in the first coupling position A, is closed. The disconnection is opened to release the connected state of the shift levers 6, 6' to obtain the second coupling position B. Opening occurs in that the separable parts of the handle 14 are pivoted apart together with the associated pins in opposite pivoting directions about the axes of the respective pins in the respective receptacles of the shift levers 6, 6'. The pins remain in the mounts of the shift lever.
  • the separation is form-fitting, for example like two gears or toothed segments that are disengaged.
  • the switching pin 12 is rotatably attached to the handle 14.
  • This embodiment is not shown, but in connection with the figures (e.g 6 , 11 ) easy to imagine. If the coupling element 11 is in the second coupling position B, in this variant the handle 14 together with the driver 13 can be rotated by 180° due to the rotatably mounted switching pin 12 about the longitudinal axis of the switching pin 12 remaining in the associated receptacle 8a. This is advantageous if the arrangement 10 has, for example, three disconnect terminals 1, 1', in which the disconnect terminal 1 with the receptacle 8a in which the coupling element 11 with the switching pin 12 is inserted.
