Abstract
Abstract A relay switching apparatus of particular utility in telephone switching installations is described. The apparatus includes a plurality of magnetically actuatable switching arrangements encapsulated in a protective cartridge. The magnetic circuits of each switching arrangement includes first and second polestrips and an armature having its movable end extended into an air-gap formed by the two polestrips. The operating parts and the supports for the operating parts are clamped in a self-gripping manner onto at least one separator piece which determines the size of the air-gap, and these parts are so secured to one another as to form a mechanical unity. The switching arrangements are divided into at least two construction groups with the construction groups being positioned one over the other, and the switching arrangements are placed in each construction group such that pairs are formed with the switching arrangements in the other construction group. The switching arrangements are clamped between the above described supports, and a case connects the supports in such a manner as to form therewith a protective cartridge enclosing all of the switching arrangements. The construction groups formed a switching arrangement compressed against the sides of the walls of the cartridge by pressure strips. Each pair of switching arrangements have a common electrical energizing circuit which includes a winding and a soft iron yoke with the shoulders of the yoke extending outside of the cartridge and being magnetically coupled to the second pole pieces in the cartridge.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
251 words
In relay apparatus having a plurality of magnetically actuatable switching arrangements encapsulated in a protective cartridge, the magnetic circuit of each switching arrangement comprising first and second pole pieces and an armature with the free end of said armature extending into an air-gap formed by said pole pieces, the operating parts and supports for the operating parts of said switching arrangements being clamped in a self-gripping manner onto a separate piece which determines the size of said air-gap, the improvement comprising: at least two construction groups formed from said plurality of switching arrangements, said construction groups being positioned one over the other, said switching arrangements in each said construction group being arranged in a row with the switching arrangements in adjacent construction groups being arranged in pairs, said pairs of switching arrangements being arranged in a single plane with the fixed ends of said armatures in each said pair of switching arrangements being adjacent to one another, at least two support means between which said switching arrangements are clamped to form a mechanical unity, case means connecting said support means and forming therewith a protective cartridge enclosing said construction groups, pressure strip means for pressing said construction groups against the walls of said case means, and common external energizing circuit means for each opposed pair of switching arrangements, each said energizing circuit comprising at least a winding and yoke means having ends outside of said cartridge which are magnetically coupled to the second pole pieces of said pair of switching arrangements.
Claim 2
Dependent Claim
