Multi-part chain links in e-chains® and transverse connecting pieces and side plates for them

摘要

The invention relates to the design of a chain link (10) for an energy chain (1) for movably transporting cables, hoses and the like. The chain link 10 consists of a plurality of individual parts 2A, 2B, 3, i.e. an inner side I facing the inside of the chain link, an outer side A facing away from each other from the inner side , and two side plates 2A, 2B of plastic comprising two narrow sides 4A, 4B running substantially parallel to the longitudinal direction, and a central part 7 at each end on both sides of the transverse connecting piece. and two transverse connecting pieces 3 for releasably connecting at least one, more preferably side plates, comprising a fastening part 6 . The side plates 2A, 2B are, on at least one narrow side, a clamping receptacle 5 having a transverse connecting piece, ie two clamping faces 5A, 5B opposite to each other in the longitudinal direction L. ), between which a complementary shaped fastening part 6 of at least one separate transverse connecting piece 3 is clamped. According to the invention, each transverse connecting piece 3 has two supporting projections 12 on each fastening portion 6 , each supporting projection having side plates 2A, 2B to achieve a solid connection. It has a support surface (13) supported against the inner side of the. The invention also provides side plates 2A, 2B in the central area between the fastening areas 5 with special function cutouts 24 and 25 in the plate body, these cutouts being additional functional or It is suggested that it facilitates the extension of the application field.
