Electrical contact arrangement

■ The invention relates to an electrical contact arrangement, in which resilient contact elements are interposed at the current transition point of two contact base bodies, which as a band or disk-shaped body with bent out of the plane of the band or disk-shaped body by twisting Contact blades are formed.

An arrangement for combining electrical contact rails is known, in which resilient contact elements are interposed at the current transition point, which have contact lamellae which are connected to the edge strips of the strip or disk-shaped contact element and bent out of the plane of the contact element by twisting (DT-PS 1 286 170). Such lamellar belts can also be used for cylindrical, polygonal and other forms of contact and stretching devices. At this

Execution is the number of contact points per unit of length limited by the fact that with regard to the deflection of the individual contact lamellae, these are not too small in their width may be measured, as a certain deflection to compensate for manufacturing inaccuracies and unavoidable positional deviations the contact body is required.

The invention is based on the object of specifying a solution in which there is practically a doubling per unit length the number of contact points can be achieved, which significantly increases the current-carrying capacity of the contact point can be achieved with practically the same space requirement, which also has a cost-saving effect. According to the invention this is achieved in that two band-shaped or disk-shaped bodies are provided, the contact blades of which are each on the one side of the band or disk-shaped body protrude further than on the opposite, and that the two "band-shaped or disk-shaped body nested one above the other in this way are arranged that the contact lamellas each with their further protruding part through recesses in each reach through another body.

The latter is explained in more detail with the aid of the drawing, which shows an exemplary embodiment of the invention. Pig. 1 shows, on an enlarged scale, a cross-sectional view of the contact element arrangement between two Contact bodies while

FIG. 2, in half representation, a top plan view with the omission of the upper contact base body from the contact elements according to Pig. I reproduces.

In Fig. 1, between the two schematically indicated contact base bodies designated by 1 and 2, the congruent lamellar strips designated as a whole by 3 and ^ are located. Each segment belt has a plurality of bent-out twist by contact blades 3a / 3b or 4a / jjb which are related via web-shaped zones 3c or ¹ respectively Ic with lateral edge strips. In relation to the plane of the band-shaped bodies 3 and 4, the curved lamella parts protrude further on one side than on the opposite side. In the case of the lamellar belt 3, these are the longer flap parts 3b, whereas in the case of the lamellar belt Ί, these are those designated with ¹ J a. The two lamellar strips 3j ¹ * are nested on top of each other, rotated by 180, so that their longer flap part 3b or 11a of the contact lamellae can pass through the recesses of the other lamellar strip created during punching and setting. This results in a sequence of contact lamellas per unit length that is practically twice as dense. In certain cases it may be desirable to prevent the two lamellar belts from slipping in the longitudinal direction

relative \ to secure. For this purpose, the band-shaped or disk-shaped bodies 3, 4 can have lugs and recesses which are curved out at their edges and which mutually engage with one another. In lateral

In any case, it is not possible for the lamellar belts to slip towards the direction, since they are generally located in corresponding recesses of the contact base body or bodies 1,2 are arranged.

Compared to known arrangements, the new arrangement allows a more compact, and thus more compact, current-carrying capacity cost-saving design of the contact point and also enables a somewhat larger positional deviation (misalignment) of the ^ Contact body.

Claims (2)

- 5 - 83/70 Claims (1. ^ Electrical contact arrangement in which resilient contact elements are interposed at the current transition point of two contact base bodies, which are designed as ribbon or disk-shaped bodies with contact lamellae bent out of the plane of the ribbon or disk-shaped body by twisting, characterized in that two ribbon or disk-shaped bodies (3, * O are provided, the contact lamellae (3a / 3b, ^ a / 4b ) protrude further (3b, ^ a) on one side of the ribbon or disk-shaped body (3, ^{2 O)} than on the opposite one (3a, ^ Jb), and that the two band-shaped or disc-shaped bodies (3, ¹ J) are nested one above the other in such a way that the contact lamellas each with their further protruding part (3b, ^ a) through recesses reach through in the other body (4 or 3). 2. Electrical contact arrangement according to claim 1, characterized in that the two bandr or disk-shaped bodies (3, 4) are secured against slipping relative to one another by lugs and recesses present on the edges, which mutually interlock.
