AI Technical Summary

Technical Problem

The existing components connected to the terminals of the battery module are not compact enough in space utilization, resulting in high electrical loss and cost.

Method used

A connecting assembly is designed in which the ends of the conductor strips are bent in a U-shaped shape to form a free flange pressed on the terminals and inserted into the U-shaped portion by screws to achieve the connection.

Benefits of technology

This design improves current conduction efficiency, reduces costs without increasing the headspace of the battery module, and does not require specialized industrial equipment.

Abstract

The invention relates to an assembly for connecting to a terminal (18) of a battery module (10) having a top (15) and a recess (14) arranged in the top, the recess (14) having a bottom (16) on which the terminal (18) extends. The connection assembly comprises a conductor bar (22) having a longitudinal portion (24) extending from an end and an opening (36) disposed through the end, and a screw (40) adapted to be inserted through the opening (36). The end portion is bent into a U shape to form a free flange (28) with the opening (36). The curved end (26) engages in the recess (14) to press the free flange (28) against the terminal (18) while the screw (40) is interposed between the longitudinal portion (24) and the free flange (28) to enable the screw (40) to engage through the opening (36).
