DE1092100B - Contact arrangement for electrical switches - Google Patents

Description

GERMAN

The invention relates to a contact arrangement in electrical switches, in which the fixed Contact is provided with a resilient part, which on the closing of the switch from moving contact yields pressure exerted in the direction of movement of the contacts.

The aim of the invention is now to provide a simple hinge for the resilient part of such fixed contacts create. This is achieved according to the invention in that the contact surface for the movable Contact-forming resilient part of the fixed contact is articulated on these by means of a leaf spring is, so that there is an articulated connection within the fixed contact.

Further features and advantages of the invention emerge from the description of one in the schematic Drawing illustrated embodiment, the invention not being shown here Embodiment should be limited.

Fig. 1 is a section through a plane parallel to the direction of movement of the movable contact, this contact being in the closed position;

Fig. 2 is the same sectional view but with the movable contact shown in the open position is.

1 is the supply line for the current to which the structure of the fixed contact is attached. 2 and 3 are flat rods cut out of thick sheet metal, which are fastened vertically to the supply line 1. the The upper flat rod 3 is provided with an opening 4 in which the end 5 of the part 6 moves back and forth can. This resilient part 6 represents the contact surface of the fixed contact against which the schematically illustrated with 12 designated movable contact of the switch when the same is switched on applies. The part 6 is bent twice at its end 5 and once at its end 7. The end 7 is according to the invention attached to a leaf spring 8, one end 9 of which is attached to the flat rod 2. the Attachment of the leaf spring 8 to the parts 2 and 7 can be done by any conventional means, however in such a way that the leaf spring rests on the flat rod 2 over almost its entire length.

A spring 10 has the tendency zuzudrücken, the resilient member 6 on the movable contact 12 and a strand 11 located 6 and the line 1 between the part provides the electrical connection Ver represent these two parts.

The position shown in Fig. 2 is that which the flexible part 6 under the action of the contact arrangement in electrical

Spring 10 and its own weight; the right end of the opening 4 serves as a End stop. The position shown in Fig. 1 is that which the part 6 under the action of the movable Contact 12 strives to occupy when the moving contact when switched on against it is pressed. The flat rod 2 also serves as a limit for the displacement of the flexible Part 6 up.

Claims (1)

PATENT CLAIM: Contact arrangement in electrical switches in which the fixed contact is provided with a resilient part which yields in the direction of movement of the contacts to the pressure exerted by the movable contact when the switch is closed, characterized in that the contact surface for the movable contact (12) forming resilient part (6) of the fixed contact is articulated on this by means of a leaf spring (8).
