Abstract
An electronic assembly contains a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point and a contact clip bridging the interruption point. The contact clip is manufactured without a preload, as a thermal fuse. The contact clip has a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder. The contact clip further has a fixing limb with a limb end seated in a circuit board opening. The limb end of the fixing limb is oversized relative to a circuit board opening, and a deformation being imparted to the contact clip, with an internal preload being generated.
Claims9
An electronic assembly, comprising:
- a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point, said circuit board having a circuit board opening formed therein;
- a contact clip bridging said interruption point, said contact clip being manufactured without a preload, as a thermal fuse, said contact clip having a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder, said contact clip further having a fixing limb with a limb end seated in said circuit board opening, said limb end of said fixing limb being oversized relative to said circuit board opening, and a deformation being imparted to said contact clip, with an internal preload being generated;
- and
- said open clip loop having between said contact limb and said fixing limb, bent loop sections and a middle loop section with at least three bending points, said middle loop section of said open clip loop having a larger section width than said contact limb and/or said fixing limb, wherein said middle loop section of said open clip loop having a punch opening formed therein, said punch opening extending over at least one of said at least three bending points of said middle loop section, said middle loop section projecting over said fixing limb in a deformed/preloaded state such that said punch opening being disposed in a projecting region projecting over said fixing limb.
