Abstract

There is provided a bend-test device for wire harnesses, capable of handling a plurality of samples at the same time. The bend-test device includes a fixed frame unit, a hinge unit with a fulcrum axis, and a mobile frame unit connected to the fixed frame unit via the hinge unit in a freely pivotable manner around the fulcrum axis. The fixed frame unit includes fixed-side panels respectively including holder holes, each of which holds a grommet carrying a wire harness. The fixed-side panels are arranged in a parallel relation to each other, and aligned perpendicular to the direction of the fulcrum axis, in a freely mountable and removable manner. Likewise, the mobile frame unit includes mobile-side panels respectively including holder holes, each of which holds another grommet carrying the wire harness. The mobile-side panels are arranged as mentioned above, so that each of the mobile-side panels can be opposed to a corresponding one among the fixed-side panels. The bend-test device further includes a pivoting mechanism for reciprocatingly pivoting the mobile frame unit relative to the fixed frame unit around the fulcrum axis of the hinge unit.

Claims12

Dependent claims

A bend-test device for bending at least one wire harness repeatedly, in order to determine the number of bending cycles leading to a breakage in the wire harness, said bend-test device comprising:

a first harness-holding unit, a second harness-holding unit and a hinge unit having a fulcrum axis, said first and second harness-holding units being connected through said hinge unit in a freely pivotable manner around said fulcrum axis;
said first harness-holding unit comprising a fixed frame unit including at least one first panel carrying at least one first holder means configured to hold a wire harness, said at least one first panel aligned substantially perpendicularly to the direction of said fulcrum axis;
said second harness-holding unit comprising a mobile frame unit including at least one second panel carrying at least one second holder configured to hold said wire harness, said at least one second panel being arranged to correspond to said at least one first panel;
and
said bend-test device further comprising a pivoting mechanism for pivoting said mobile frame unit reciprocatingly, relative to said fixed frame unit, such as to yield a predetermined pivoting angle around said fulcrum axis of said hinge unit.
