DE1962558C - Cross connection slide - Google Patents

Description

The invention relates to a cross-connection slide, which above the head surface of a Terminal arrangement is movably mounted and directly or indirectly with the contact parts of the Single terminal is connected, especially for side-by-side electrical isolating terminals that are used for test and measurement purposes are used.

Such separable terminal blocks are mainly used in number measuring circuits. They allow, that permanently installed measuring instruments can be checked with a comparison instrument. The known terminal blocks are designed so that optional contact parts for a longitudinal disconnect, Cross disconnect or through terminal can be inserted. With the appropriate accessories various circuits can be carried out. The connection and disconnection of the two connected The ends of the conductors are carried out through a slide valve.

During the check it can happen that the connected converter coils are short-circuited. To do this, it is necessary to connect the converter connections, which are usually routed to neighboring terminals, to one another by pressing. So far, a swiveling cross-connection bracket has been used, or else a fixed bridge has been inserted. It is known ^f erner an embodiment in which a movable cross-bridge slides on the insulating material. However, these known arrangements have the disadvantage that the cross-connecting bridge can only be moved and screwed tight using an additional tool. Furthermore, there is also insufficient protection against touching bare contact parts. So is z. B. in the German Auslegeschrift 1 060009 dargesteii a test terminal. and described, in which a block-shaped, conductive connecting piece can be pushed back and forth captively in dovetail-shaped guide grooves directly on the clamping body of a switchgear modular terminal block. A comb-like bridge is used for the actual bridging. By shifting the length of the connecting piece directly "on the clamp body" in this version of cross connections b;: i of constant clamp size no more test and ίο, ic bushings should be attached, however, if such Prm and measuring bushes are attached, they would be through the slide Even the recessed arrangement of the cross-connecting links within the terminal support means that there is no protection against accidental contact. It is also important that the terminals are not designed in accordance with all the high requirements of the relevant regulations according to the German interpretation. This can happen that only a minimum of air or creepage distance is available when the cross-connection is open, ie for example a lower nominal voltage.

From the German Offenlegungsschrift 1 805 52: a cross-connection slide is known the one, which is arranged on the top of the insulating housing ^. But this version has its aftermath part that to guide the cross-connection slide ^ the leg ends with guide lugs and the insulating housing with a corresponding guide must be provided with a groove, d. h \, there are additional costs in the production and assembly of such Cross-connection arrangements. In addition, depending on the tolerance and width of the Isolierjtnffgehäuses the The wall thickness of the guide groove fluctuate. This cross-connection slide can thus light at al len prefabricated insulating material housings are used.

The ones shown in the German Auslegeschrift 1 132 618 Cross connections do not meet all the requirements nowadays for such cross connections fertilize. So is z. B. no protection against accidental contact present when the cross-connection slide is energized It can even happen that even in the disconnected state, the cross-connection slide can be under tension, d. H., the slide can only be operated with an additional tool isolated from voltage.

The switching and cross connection shown in the German utility model 1 861 564 is liable also has the disadvantage that the contact parts are not arranged to be protected against accidental contact. Furthermore it is It is not possible to install test and measuring sockets in such a way that they are always accessible. Through the sunk Arrangement of the cross-connecting elements and the superimposed, pivotable switching elements is a clear design of the entire switching and cross-connecting links is not possible.

The terminal block shown in the German Auslegeschrift 1087 660 can only be used for longitudinal separations execute. The terminal is in no way intended for test and measuring circuits, e.g. for counter measuring circuits, to use. There is no provision for cross-connection to neighboring terminals.

In the German Auslegeschrift 1205 603 are

Cross-connecting bridges shown. These bridges - connect neighboring switchgear rows, clamp. Any circuits or Trennun- "pfi in longitudinal and transverse direction for test and ^ j _e ßzvvecke themselves can not perform.

Mistake. The insulating cap 25 is preferably molded onto the head 28 of the fastening screw 14 (15), and / was such that in the lower area of the screw head 28 there was a shoulder-shaped projection 29 results. The surface 30 of the screw head provides the electrically conductive connection via the cross connection bridge 20 of the cross connection slide H and the spacer sleeves 13 and the fastening screws even to the Konlakttcilcn 2, z. B. two neighboring terminals.

As can be seen from Fig. 3 to 6, is on the Oucrverbindimgsträgcr 19 a cross connecting bridge 20 attached. The cross-connection bridge is folded in a U-shape and has two holes 21 provided that when the cross-connection bridge is pushed on 20 on the cross-connection carrier 19 in the projecting lugs 22, preferably round Cross-section, snap into place and thus firmly connect the two parts to one another.

So that the cross-connecting layer 12, consisting of cross-connecting beam 19 and cross-connecting bridge 20, has a smooth surface, the Cross connection beam 19 with a shoulder-shaped projection 23, corresponding to the material thickness the cross connection bridge 20, give away. The cross-link bridge 20 is made of flat material in a U-shape and provided with recesses 32, which the slot-shaped recess 31 of the cross connection carrier are adapted.

On the part of the cross-link 19, facing made of insulating material and the cross connection bridge 20, which is folded from a U-shaped sheet metal but a cross-connection barrier can also be used in which the cross-connection bridge and the cross-connection beam represent a whole and preferably a material with high electrical conductivity is used. It is also possible to use a massive cross-connection bridge Material with high electrical conductivity too

ίο then use the cross connection beam made of insulating material is molded onto the cross-connection bridge.

A bipolar cross-connect circuit has been shown and described. Same execution and mode of operation is also possible with multi-pole (e.g. three- or four-pole) cross-connection switches.

The advantages achieved with this invention relate in particular to switchable Rcihenklcmmen, where the loosening or fastening of a cross connection by hand or with a screwdriver takes place without the aid of additional tools. Furthermore, the manufacture and assembly of such Cross-connection slide is significantly

as fold.

Another advantage of this design is the protection against touching bare contact parts Oucr connection sliding crane arrangement in non-interconnected The state of two or more neighboring terminals can be seen.
