Definitions

the invention relates to a resilient pressure contact with a movable contact head, as defined in the preamble of claim 1.
the contact head moves axially against a spring force within the resilient pressure contact in contact with a fixed contact within its guide sleeve.
the current transfer between the contact connection and the movable contact head takes place through copper strands within the guide sleeve. A not inconsiderable manual manufacturing effort is required for the production. If the number of contacts is high, the inner copper strands often break.
the object of the invention is to improve the service life of the resilient pressure contacts in the direction of increasing the number of possible contact strokes, to increase the reliability by avoiding or reducing strand breaks, to reduce the overall manual production effort and at the same time to increase the current carrying capacity.
Fig. 1 the basic structure of a resilient pressure contact can be seen. Thereafter, a metallic contact head 2 made of solid material with contact pieces 1 is mounted in a guide sleeve 3 so that it cannot rotate, but is displaceable. A compression spring 4 holds the contact head in the position shown. During a coupling process, a force P presses in the direction of the arrow and the contact head 2 is pressed - here to the right - by pressing the compression spring 4. The electrical connection is made via a screw bolt 5, the current transfer from the fixed connecting plate 7 to the movable contact head 2 via various copper strands or bands 6 is effected. The latter are introduced with a twist and soldered at the ends.
Fig. 2 now shows a new contact head 2a.
the fit dimensions are the same and therefore interchangeable.
the copper strands 6 are now eliminated.
the new contact head 2a On its side facing away from the contact pieces 1, the new contact head 2a is partially designed as a hollow cylinder 8 and is provided with slots 9 which are radial to the longitudinal axis.
the remaining wall sectors form contact tongues 10 which, according to FIG. 3, abut on the inside of the guide sleeve 3 and thus serve to transfer current from the connecting bolt 5 via the guide sleeve 3 to the contact head.
the profile of the Kostaktzonne 10 is formed by an undercut with a contacting area 12 of the largest outside diameter on the very outside on the side facing away from the contact pieces 1 and inwardly adjoining areas with reduced outside diameters, the smallest outside diameter located at the end of the radial slots 9 being the tongue fixed points 13 for the Tongue movement determined.
the compression spring 4 of the resilient pressure contact engages centrally in the hollow cylinder 8 of the coupling head 2a, is supported on the base 14 and is fixed there. Snap rings can be inserted in one or more circumferential inner ring grooves 15 to increase the contact pressure.
the necessary high electrical conductivity as well as resistance to abrasion are ensured through a suitable choice of materials.
the new pressure contacts remain unchanged from the previous design.
the new contact head is fully - ie mechanically and electrically - compatible with the previous ones.
