- the circuit diagram shown in Fig. 25 shows a third embodiment.
- the third embodiment differs from the second game personssbei only in the switching function of the switching contacts 18a, 22, 23; 18'a, 22 ', 23'; 18 "a, 22", 23 ".
- the switching contacts 18a, 18'a, 18''a only connect the connections L1, L2, L3 of the connection section 17 of the plug-in unit 14 via the contact sections 23, 23 ', 23 "Of the bridge connector 24.
- the contact sections 22, 22 ', 22" are no longer connected to the switching contacts 18a, 18'a, 18 "a.
- the contact sections 26, 26 ', 26 "of the plug section 16 of the plug-in unit 14 are no longer short-circuited, but the connections L1, L2, L3 of the connection section 17 of the plug-in unit 14 are short-circuited via the bridge connector 24 .
- the switching contacts 18a, 18'a, 18 "a” each form a changeover between the respective contact section 22, 22 “, 22" and the respective contact section 26, 26 “, 26”.
- 29-36 show schematic representations of arrangements 20 according to the invention in different variations. These are just a few of the possible combinations of plug-in units 14 and isolating terminals 1, T, 1 ”. Other combinations are of course possible.
- FIG. 29 three isolating terminals 1, T, 1 "and a plug-in unit 14 are shown schematically in a separate position, FIG. 30 depicting a connected position of plug-in unit 14 and isolating terminals 1, T, 1".
- the second connection section 3 of the isolating terminals 1, T, 1 ′′ and the plug-in section 16 of the plug-in unit 14 are connected (electrically conductive as described above).
- FIG. 31-33 each show connected positions of plug-in unit (s) 14 and isolating terminals 1, 1 ', 1 ”(-1 v ).
- the plug-in unit 14 has two plug-in elements 15,
- FIG. 32 Another variation of a plug-in unit 14 with six plug-in elements 15-15 VI shown in FIG. 32 with six disconnect terminals 1-1 Vl.
- FIG. 33 shows two plug-in units 14, each with three plug-in elements 15, 15 ', 15 "and eight isolating terminals 1-1 vm .
- the free isolating terminals 1 Vl -1 vm can be used for other purposes or they can also be free, for example for later use.
- Fig. 34 are two arrays 20-1, 20-2 consecutively inserted and connected
- Fig. 35 shows a variation with three arrays 20-1 to 20-3
- Fig. 36 illustrates a gun clean the other connection of n assemblies 20 n.
- FIG. 37 shows a schematic flow diagram of a method according to the invention for short-circuiting an arrangement 20 of at least two isolating terminals 1, T, 1 ′′ with at least one plug-in unit 14.
- plug-in unit 14 and isolating terminals 1, T, 1 ′′ are put together (see FIGS. 1, 2). So that an Radiozu was the arrangement 20 is established.
- the isolating terminals 1, T, 1 ” are in the first switch position A and the plug-in unit 14 is in the plug-in position D, the second connection section 2 of the isolating terminals 1, T, 1” being electrically conductively connected to the plug-in section 16 of the plug-in unit 14.
- the external connections L1, L2, L3 of the connection section 17 of the plug-in unit 14 are galvanically separated from one another.
- a second method step VS2 the first switching position A of the isolating terminals 1, T, 1 ”is adjusted to intermediate switching position B, the plug-in position D of the plug-in unit 14 is retained, and there is no short circuit in the plug-in unit 14.
- the passage from the first connection section 2 of the isolating terminals 1, 1 ', 1 ”to the external connections L1, L2, L3 is still given.
- the isolating terminals 1, T, 1 When leaving the intermediate switching position B and assuming the second switching position C, the isolating terminals 1, T, 1 ”are short-circuited. The passage from the first connection section 2 of the isolating terminals 1, T, 1 ”to the external connections L1, L2, L3 is no longer available. The plug-in unit 14 remains in its first plug-in position D. The external connections L1, L2, L3 are short-circuited, although there is no short-circuit in the plug-in unit 14.
- the isolating terminals 1, T, 1 ′′ are in the first switching position A and the plug-in unit 14 is pulled into the intermediate plug-in position E. There is still passage from the first connection section 2 of the isolating terminals 1, T, 1 ”to the external connections L1, L2, L3. There is no short circuit in the isolating terminals 1, T, 1 ”.
- the arrangement is separated.
- the plug-in unit 14 is pulled out of the isolating terminals 1, T 1 ", with a leading short-
- the external connections L1, L2, L3 of the connection section 17 of the plug-in unit 14 short-circuits, this short circuit of the external connections L1, L2, L3 of the connection section 17 of the plug-in unit 14 continuing to exist when the plug-in unit 14 is in a Third plug-in position F is completely pulled out of the isolating terminals 1, T, 1 ′′ and the arrangement 20 is disconnected.
- the passage from the first connection section 2 of the isolating terminals 1, T, 1 ”to the external connections L1, L2, L3 is separated.
- the isolating terminals 1, T, 1 ver remain in the first switching position A.
- the isolating terminals 1, T, 1 are short-circuited in the second switching position C, with the plug-in unit 14 in the intermediate -Connection position E is pulled.
- the isolating terminals 1, T, 1 ′′ remain short-circuited and the plug-in unit 14 experiences a leading short-circuit of the external connections L1, L2, L3. This means that two short circuits, that of the isolating terminals 1, T, 1 ”and the external connections L1, L2, L3 are connected in parallel.
