ABSTRACT:
To introduce wire coils into stators of electric machines, improved isertion strips are proposed. To make the production of the insertion strips (1) cheaper and, in particular, to make it possible to use them for the joint insertion of interconnected coil groups, the insertion strips (1) are made of plastic. They consist of two elastically spreadable tongues, in which guide lamallae (15) made of spring steel are embedded. A foot part (4) is molded on one end of each tongue for releasable mutual connection and for attachment to an insertion tool (E). The foot part adjoins a parallel region of the tongues, which in turn adjoins the spread region of the tongues with an increasing distance between them up to the tongue tips (12).
Crosspins engaging into corresponding holes in the adjacent tongue of the next adjacent insertion strip block the wire passage between the strips.
