Battery Feedthrough Assembly With Riveted Clamping for Stable Sealing

The patent replaces the welding process (thermal-mechanical system) with a mechanical fastening system consisting of a clamp, fastening bolt, and fastening nut. This substitution eliminates thermal effects while maintaining connection strength through pure mechanical forces, thereby preserving the sealing performance of the housing assembly.

The patent introduces a clamp as an intermediary component between the feedthrough assembly and the housing assembly. The clamp distributes the fastening forces over a larger area, preventing localized stress concentration that would compromise sealing. The intermediary structure transforms point loads into distributed loads, protecting the housing assembly from stress-induced sealing failures.

The patent substitutes the welding process with a mechanical fastening system using a clamp and fastening bolt. This replacement maintains structural integrity through mechanical interlocking and clamping forces while avoiding thermal effects that disrupt the housing assembly's stress distribution and compromise sealing performance.

The clamp serves as an intermediary that distributes fastening forces across a broader area of the housing assembly. This distribution prevents localized stress concentrations that would otherwise occur with direct fastening, thereby maintaining both structural integrity and sealing performance without thermal interference.
