Abstract
Abstract The multiple holding arrangement according to the invention consists of two guide plates of the same kind, which are specially shaped and provided with rows of lamination-like resilient web portions comprising widenings. The resilient web portions serve to compensate for thickness tolerances of plug-in units, and the widenings serve to avoid overstretchings of the web portions in the case of twisted plug-in units.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A multiple holding arrangement for a plurality of plug-in units, including a structural unit and two guide plates mounted thereon, each plate comprising: a plurality of pairs of resilient webs, each pair establishing an indentation for receiving each of said plug-in units, each of said indentations having a narrow central portion for engaging each said plug-in unit, that portion of said web adjacent the central portion of said indentation extending outward toward a similar web portion of an adjacent pair, whereby upon insertion of an improper plug-in unit, the adjacent web portion abuts and touches the neighboring adjacent web portion prior to reaching the stretching limit of the stretched resilient web.
Claim 2
Dependent Claim
111 words
