Definitions
- the invention is in the field of electrical components and is in the structural design of vacuum interrupters apply, the contact arrangement of two coaxial arranged contacts with facing contact surfaces exists, with each contact as a flat, Mobilear-miger Spiral contact formed and at least one contact is axially movable.
- Such contacts have in all Usually four arms, but can also be formed six-armed be (DE 196 24'920 A1).
- Embodiments of the spiral contacts is the inner one Area of the contact surface formed as a recess, so that the intended for the switching of operating currents contact area with that for switching off short-circuit currents provided contact area is identical (EP 0 532 513 B1, DE 198 02 893 A1, DE 199 10 148 A1).
- the object of the invention is to design the contact arrangement in such a way that the mechanical contact point between the two contacts on several separate individual contacts with a defined spring constant is distributed and that nevertheless the rotation of a Arc is possible.
- each contact as at least two-layer contact body with a lower layer of a highly elastic material and an upper layer of a good electrical conductivity Material exists, with both layers cohesively connected to each other, and that in the outer area each Needlesarmes arranged a pad of a contact material is.
- the contact arrangement are through a layer structure of the individual contacts the functions mechanical stability and electrical conductivity separated, wherein in the mechanical Stability-ensuring layer additionally spring properties integrated by the electrically conductive Layer are attenuated only slightly.
- the mechanical Stability-ensuring layer additionally spring properties integrated by the electrically conductive Layer are attenuated only slightly.
- the individual spiral contacts can from a electrically well conductive, relatively expensive Material existing layer can be kept as thin as it which require electrical requirements.
- By the back feeding this layer with a resilient layer is a premature fatigue break the - usually - made of a brittle contact material existing electrically avoided conductive layer.
- Suitable for these purposes preferably materials from the group of stainless steels while high-purity copper for the electrically conductive layer should be used. It is useful for the lower and the top layer has a thickness of about 3 to 5 mm each and for the edition a thickness of about 2 mm is selected.
- This edition is suitably made of a material that copper and Contains chromium, preferably from a proven copper-chromium sintered material. Optionally, this material can also be used for the electrically conductive layer. In this Case can be to ensure the required electrical Properties between the two layers a copper layer be arranged.
- the contacts As 5-, preferably Form 6-arm spiral contacts.
- the two contacts 1 and 2 of the contact arrangement according to FIG 1 are formed according to Figure 2 as dearmige (10) spiral contacts and consist of a contact carrier 3 and the actual Contact body 4.
- each disc-shaped contact body 4 has a lower Layer 6 and an upper layer 7; the layers 6 and 7 are materially interconnected, in particular soldered. On the upper layer 7 contact pads 9 are arranged.
- the contact body 4 sits on a contact carrier. 3 on, which is provided with a gradation 8 and by a Drill hole in the lower layer 6 directly with the upper Layer 7 is connected.
- the contact carrier 3 made of high-purity copper
- the lower layer 6 made of a stainless steel
- the top layer 7 of high purity copper and the contact pads 9 made of a copper-chromium sintered material.
- the contact arms 10 of the two spiral contacts 1 and 2 formed by special slots 11, similar the arrangement known from EP 0 532 513 B1.
- pie slots are worked out of the disk-shaped contact body 4, having a central recess 5, so that at Switch the insertion of the arc in the area of the arms is guaranteed.
- Each contact support 9 is at the Ends of the contact arms 10, ie in the outer region of the contact arms, arranged.
- FIG. 3 shows a contact body 12, which has six arms is, being at the ends of the spiraling Contact arms 13 each a contact pad 14 is arranged.
