"Electrical contact device"

The innovation relates to an electrical contact device with zv / ei cooperating optionally with one another j contacts to be brought into contact and separated from one another, one of which is resilient contact elements has, which pressed in the contact-making state of the device against a contact surface of the other contact are.

Its purpose is a contact device of this

j to create a type that is extremely simple in construction,

can exert a large contact pressure and both for

small as well as large currents can be carried out. According to the innovation, this is achieved by the Contact with the resilient Kontaktorganeη from a holder with at least one stack of identical and aligned, V-shaped folded, nested, resilient metal plates, which can be tilted around the fold in the holder, on the spot or in are secured against lateral displacement in the vicinity of the fold, with their free edges parallel to the fold lie against a contact surface of the holder and with their other free edges parallel to the fold one with the other contact form cooperating contact surface.

Will contact with the resilient, V-shaped folded plates with the other contact in cooperation then the two come together in a second fold Parts of the panels are resiliently pressed towards one another and the free edges parallel to the fold then come to lie with great pressure against the contact surfaces of the holder and the other contact. By. Enlargement Depending on the length and number of plates, the contact device can be designed for large currents

Contact devices of this type are for the separable connection of parts of switching devices for De-energized disconnectors, earthing contacts, etc.

suitable. A very simple contact device is obtained if the construction of the same is carried out in such a way that that the parts of the plates extending between the palte and the contact surface of the holder on both Ends of the plates with respect to those between the palte and those cooperating with the other contact protruding free edges extending parts of the plates and with their projecting parts in grooves grip of the holder, the distance between the front wall of these grooves and the contact surface of the holder is smaller than the width of the plate parts engaging in it. The protruding plate parts can then only be placed at an angle in the grooves of the holder. Become the V-shaped folded plates through the other contact pushed back, the plates are folded around their palte and the protruding plate parts sit down clamped firmly between the front wall of these grooves and the contact surface of the holder so that good electrical contact is made between the plates and the holder will. To make the contact pressure between the plates and the contact surface of the holder particularly large, what is necessary, as the plates and this contact surface is nittht shifted to one another and therefore not always rein-

be scraped, as happens between the other contact and the plates, an execution is recommended, being between the palte and the contact surface of the holder extending parts of the plates a smaller width than that between the Palte and with the have other contact cooperating free edges extending portions of the plates. This will the pressure exerted on the plates by the other contact is increased by leverage on the contact surface of the holder.

It has been shown to be advantageous if the V-shaped folded plates are removed by means of puddle strips are kept from each other. The edges of the panels, which come into contact with the contact surfaces of the holder and the other contact can then move a little move with respect to each other so that each plate adjusts itself in the most favorable way for the contact pressure can. The 3? Üll strip η can be used in a holder with grooves to hold the V-shaped folded plates also grip their ends into the grooves of the holder. she then need ksine additional fasteners.

The innovation will be explained in more detail with reference to the drawing. In the drawing is:

Fig. 1 is an axial section of an electrical contact device after the! inflation and

Pig. 2 is a cross-section along the line H-II in Pig. 1.

The contact device according to the drawing consists of two cooperating, optionally to be brought into contact with one another and to be separated from one another contacts 1 and 2. The contact 1 is a solid contact which is movably arranged in the direction of the arrows 1a (Pig. 2). The contact 2 consists of a fixed holder 3 and two stacks of identical and uniform, Y-shaped folded, resilient, metal plates 4 arranged opposite one another in the holder.

and their parts 4a, 4b, which come together in the dtr Palte, have different widths. The narrower 'parts 4b are longer than the wider portions 4a and engage with their projecting parts 4c in the axial N _u th 6 of the holder 3. Between the muting 6 the holder is provided with flat contact surfaces. 7 The racks 6 are arranged and designed in such a way that the distance between their front wall 8 and the relevant contact surface 7 is smaller than the width of the narrower plate part 4b, see above

that the plate parts can only grip into the hats 6 in an oblique direction. The plates 4 come with their 2ur fold 5 parallel free edges 9 against the contact surfaces 7 of the holder and with their free edges 10, which are also parallel to the fold, against the contact surfaces 11 of the movable contact 1 when the latter is in contact 2. Through contact 1, the V-shaped plates are resiliently compressed, with the result that the edges 10 with a

certain force against the contact surfaces 11 of the contact ie edges 9 J

a great force ada e

are printed against the contact surfaces 7 of the holder 3. So that each plate 4 can freely adjust so that all plates come to rest against the contact surfaces 7 and 11 with the required pressures, ^{strips 12 are arranged between the plates 4 I 1} UIl, which also engage with their ends in the grooves 6 . To enclose the stacks of plates in the holder 3 , closure plates 12 attached to the holder are attached «

For an axially movable contact 1, the V-shaped folded plates 4 in a polygon around this Contact can be arranged. Also, the V-shaped folded plates 4, if this is in relation to the movement

aes movable contact should be more favorable, be arranged in the opposite direction in the holder, so that the free edges 9 and 10 are turned towards the bottom of the holder 3 _{or the like}
