Federal Republic of Germany-Förbundsrepubliken Tyskland (DE) P 255579 ^ .2 Proven-Styrkt (71) Krone GmbH, Goerzallee 311, 1 Berlin 37 »Federal Republic of Germany-Förbundsrepubliken Tyskland (DE) (72) Joachim Rott, Berlin, Hermann Herfort Federal Republic of Germany-Förbundsrepubliken [fyskland (DE) (7 ^) Berggren Oy Ab (5U) is formed in each case in the form of a plurality of preferably overvoltage protectors arranged in two rows and arranged in two rows relative to one another, which can be inserted into the separating strip holder and which has a through-ground rail on one side, the pusher unit being assembled from two the shields at their points of contact with the compression pressure of the springs are in contact with the contact strips.

According to an embodiment of this prior development, it is characteristic of said overvoltage protection device that compression springs arranged in the cup-like bulges of the artificial plate are used as springs,

Furthermore, according to another variant of this prior development, care has been taken that the artificial compression body to be placed in the artificial housing chamber and the support springs supported in this synthetic housing hold the contact strips pressed together and press the edge bending opposite said edge bending can be pressed against the artificial compression body, the compression pressure resting on the second contact point of the surge protector.

The present invention relates to a preferred further development of a previously developed surge protection device for isolating strips according to one or the other variant.

It is an object of the present invention to provide an overvoltage protection device of the above-mentioned quality, which can be used without tin pieces and also with tin pieces without said rearrangement of components.

Alternatively, this task is solved by measures according to requirements 1 and 2. These measures have the advantage that, in the manufacture of this mass article, only two parts have to be kept ready and, if necessary, one or the other part is placed in place, so that in both cases the same housing made of two artificial plates can be used.

Embodiments of the invention will now be described with reference to the accompanying drawings.

Figure 1 shows a front view of a pusher part according to the invention with its surge protectors pushed into place, the parts partially removed in order to make the special nature of the contact more visible.

Fig. 2 shows the pusher shown in Fig. 1 cut along the line I-I, the device being provided with a spring device for clamping a surge protector without a piece of tin.

Fig. 3 is a front view, however, of the pusher part of Fig. 1 with its surge protectors in place, each with a piece of tin.

Fig. 4 shows a side view of the pusher according to Fig. 3 and a section along the line II-II, provided with a spring device for pressing the overvoltage protection and the tin piece into place.

Fig. 5 shows a front and side view of the ground contact device in the device according to Figs. 1 and 2.

Figure 6 is a front and side view of another ground contact device for the device of Figures 3 and 4.

According to Figures 1 and 3, the overvoltage protection device in the form of a pusher, which is improved compared to the previous development, consists of two artificial plates 1, 1 'and new contact elements 3', 6 'placed between them.

When previously two different embodiments of the pusher part were used for both uses, namely the surge protectors 5 without the tin pieces 13 or with the tin pieces, a new design is used here, which is used for both uses.

According to Figure 1, the new pusher part consists of two shaped artificial plates 1 and 1 '. These new parts 1, 1 'can also be seen in Figure 3, have the same embodiment and are similar in coverage.

The part 1, which is formed of a pressed or cast active material, acts as a pusher in each of the many separating ribs of the main distributor.

Part 1 or 1 'has two rows of openings 4, 4' arranged offset relative to each other. The placement of surge protectors offset in two rows is known per se from German design protection 1 951 560.

As can be further seen from Fig. 1, the contours 1c of the openings 4 of the part 1 are in line with the contours 1'c of the plate 1 ', which plate 1' in the representation of Fig. 1 is located on the plate 1. When the plate 1 'has openings with an outline 1'c, the openings 4 behind the plate 1 have two cross-sectional triangular strips or extensions Id which form responses to the surge protectors and protect them from falling - in Fig. 1 backwards. Since these outlines are not present in the contours of the openings 4 'of the plate 1', the surge protectors 5 can only be removed - as shown in Fig. 1 - from the front.

Above each surge protector 5, the plate 1 has - as in the previous embodiment - a row of compression springs 9 receiving cup-shaped bends 10 ', except that in the present application the bulge 10' and thus the spring 9 therein have the same magnitudes for all surge protectors 5, so only one only a series of identical compression springs 9 · The space thus left free of the plate 1 is used according to the invention for two other advantageous, complementary pusher devices.

A control is now provided for the contact springs 6 'under spring pressure and thus movable. This is obtained from the longitudinal opening 6'c in each contact spring 6 'in cooperation with a collar edge Ib formed on the plate 1. This collar edge Ib is arranged centrally from a bore 1a extending through the plate 1.

Adjacent to these bores 1a are the pins 1'a formed along the entire length of the plate 1 '(cf. Figs. 2, 4), so that the plate 1 * can be precisely placed on the plate 1 and the plate 1' is centered on the plate 1. The plate 1 'can be thus also called the overprint plate. The free ends of the pins 1'a, which can also be displaced in a second row below the top row (shown), can be welded to the plate 1 at its exit point from the plate 1 (Fig. 4) or glued or otherwise attached, for example.

It should also be noted that the surge protectors 5 ~ as shown in Figures 1-3 - are arranged axially in the plane of the plates 1, 1 'and the thicknesses of the plates 1, 1' are chosen so that the surge protectors 5 are securely arranged.

This arrangement and placement also has the advantage that the surge protectors can be easily and quickly replaced and replaced without additional aids.

It is particularly important to arrange the contacts of the surge protectors 5 between the plates 1, 1 'forming the flat housing.

For this purpose, contact devices 3 ', 3' 'and 6' are arranged between the plates 1, 1 ', which at the same time also have contacts 2 known per se, respectively. 6a for the separation bar.

5 62604

In order to connect the possibly foreign voltage-carrying contacts of the separating strips, head-side contacts 6a are arranged in each contact strip 6 '. For the contacts of the surge protectors 5, the lower ends of these contact strips 6 '(Figures 2 and 4) have a first inverted part 6'a and henceforth a second inverted part 6'b. The latter extends in the direction of the bottom contact and may be divided to fit the rounding of the surge protector to which it forms a response.

This shape of the contact strip 6 'is the same for both applications, namely with and without a piece of tin.

For different ground or ground contact, two different but almost repetitive metal strips 3 'resp. 3 ''.

According to one embodiment (without a piece of tin), a first part 3'a is bent at the upper end of the metal strip 3 '(Fig. 2) for contacting the surge protector 5 and a continuous downwardly bent part 3'b resting on its free end resting on the shaped part Ic.

According to another embodiment (with a piece of tin), the metal strip 3 '' has a first bent part 3 "a and a continuous second, upwardly bent (Fig. 2) part 3" b, the length of which is dimensioned so that when the piece of tin 13 is in place a gap 3d of the contact strip 6 'to 6'b.

All, in this case ten metal strips 3 'are connected to the ground rail 2 on the ground side and form an electrically conductive structural unit 20 (Fig. 5) ·

Similarly, all the metal strips 3 "with the ground rail 2" form an electrically conductive structural unit 21 (Fig. 6).

Thus, for one or another use, according to the invention, it is only necessary to replace the structural units 20 resp. 21 (with a piece of tin).

The tin piece 13 then acts in a known manner as an additional heat shield and melts under the effect of the applied voltage and heating to about 100 ° C, so that the contact strip 6 * b is in short-circuit contact with the metal strip 3 "d under the pressure of the spring 9.

6 62604

In order for the surge protector 5 to rest even better on electrical contacts for electrical and mechanical reasons, the metal strips 6 resp. 3> is the contact protrusions obtained by bending in parts 6'a and 3 * a and 3 "a for the contact buttons (s) on the front sides of the surge protector 5.

Also, these new contact strips 6 '- as in the previous development form - are connected to each other by transverse strips before installation and can thus be placed between the artificial plates 1, 1' in a single operation. After the plastic sheets 1, 1 'have been joined together, e.g. by ultrasonic welding, these transverse strips are punched out through openings 7 provided for this purpose. In Figures 1 and 3, the extensions 6c remaining after stamping can be seen.

As already suggested, the two stops 8, 8 'formed on the synthetic plates 1, 1' determine the insertion depth and thus ensure that the contact 6a of the pusher part is connected to the contact of the separating strip in the right place.

The abutment 8 also has a notch 8 "which allows the pulling tool to be gripped to facilitate the possible pulling of the pusher part out of the dispenser rack. A pulling tool for this purpose has already been described in German design protection DT-74 20 467.
