Reception contact for NH fuses.

The invention relates to a receiving contact for NH safety devices, with contact arms rotated by 90 ° with their broad side on the knife-like mating contact.

The essential feature of the invention is that each of the contact arms through one or more incisions in individual Slats is divided.

The subdivision of the contact arms offers the possibility of providing each lamella with an external spring to reduce the contact pressure to improve and to increase the power transfer points. This reduces the voltage drop at the contact point and the heating of the contact kept low *

In one embodiment of the invention, the foreign springs are placed through a slot in the lamellae and their ends are supported in grooves in the lamellae. The external springs of two pairs of lamellae arranged next to one another can also be laid jointly through the incision in these lamellae and held with their ends in impressions of the lamellae. Furthermore, the foreign can fire a stop for the penetration of the counter-K 'ι η t; :. & t ew υ J. 1 de η.

With the contact an additional part in the form of a Veri-vbiirkungstniles twist, the latter together with the '■ Con i; as: ti "u ^ is attached to the laolier base. Branches at the free end the reinforcement part is divided into two arms, which in Abi ;: :.; u-a,; ijii overlooked and the spring deflection of the slats to the outside

boundaries. On the opposite edges of the bends in the reinforcement part, noses are expediently provided Prevent the slats from bending sideways. The reinforcement part can also act as a stop for the penetration of the Form mating contact.

Exemplary embodiments of the invention are shown in the drawing. Show it:

Fig. 1 a receiving contact in side view and partially cut along the line A-B of Fig.3 » a partial section along line E-3? Fig. 1 - a section along the line G-D of Fig.2,

a stamped part for contact according to Fig. 1-3 on a smaller scale.,

a stamped part for another contact on a smaller scale ..,

an arrangement for two individual contacts as shown in Fig. 1-3,

a side view for a double contact,

a contact according to Fig. 1-3 with a reinforcement part in side view and partially sectioned along the line G-H in Figure 10, a section along the line I-K in Fig. 8, a section along the line L-M in Fig. 8.

The receiving contact according to Fig. 1-3 of the drawing may be made of tape produced, as can be seen from the stamped part 19 of Fig.4 is. The contact arms 4,5 resulted from a, Incision 20 of the stamped part 19. They are 90 ° in the longitudinal direction twisted.

Each of the contact arms 4, 5 is subdivided into two lamellae 8, 9 and 10, 11, respectively, by an incision 6, 7. The slats 8-11 lie with their broad side on the knife-like mating contact 12 of the fuse cartridge 13. The recording contact is with its contact foot 2 attached to the insulating base 1 by means of screws 3.

The foreign springs 14 are through slots 17 of the plate pairs 8,10 and 9.11 lived and with their ends 15 in indentations 16 of the Slats stored. At the same time, the foreign springs form 14 stops 18 for the penetration of the mating contact 12 into the contact,

The subdivision of the Kontaktaxme can also be in more than two lamellas take place. The stamped part 21 according to Figure 5 shows a subdivision of the contact arms into three lamellas each.

The arrangement according to Figure 6 represents one of two individual contacts, existing double contact. The contact feet 2, 2 a are put together and fastened to the insulating base 1 by means of screws. The arrangement of the foreign springs 14 takes place on the contact arms 4 as already described, on the other hand the foreign springs 14a are the Contact arms 4a passed through the incision 6a between the lamellae 8a, 9a and with their ends in impressions 16a of the Lamellas stored »

The double contact according to Figure 7 has a common contact foot 32, which by means of a screw 33 on a busbar is attached.

The receiving contact according to Fig.8-10 is with a reinforcement part provided, which is fastened with its foot 22a together with the contact foot 2 on the insulating base 1 by means of screws 3.

The reinforcement part 22 is hooh guided with two arms 23,24 on a rope of the contact. The arms 23> 24 are followed by Kh ₁ bends 26, 27, which rest with their inner edges 28, 29 on the outside of the lamellae and thereby limit the spring deflection of the lamellae when the countercontroller 12 is inserted. On the inner edges 28, 29 there are lugs 30, 31 which each grip over the end and zwlsohei /, the lamellae and thus prevent the lamellae from bending out to the side when the fuse cartridge 13 is inserted and withdrawn.
