Solution Overview

Problem

Conventional detection assemblies in sensors are prone to deformation under external forces, affecting detection accuracy and leading to potential connection failures between the lead electrode, detection element, and conductive terminal.

Innovation Solution

The detection assembly is designed with a lead electrode having a connection portion and an extension portion, where the lead electrode and conductive terminal are positioned to minimize protrusion, reducing deformation under external forces. The conductive terminal has a first terminal end and a second terminal end, with specific tips and orientations that support the lead electrode, thereby reducing its deformation.

Solution Approach 1:

The patent changes the spatial arrangement by positioning the lead electrode and first terminal end on the same side of the second tip along the extension direction, and arranging the connection portion and extension portion at specific orientations (same side or perpendicular). This dimensional reconfiguration reduces the protruding length of the lead electrode while maintaining manufacturability, thereby reducing deformation under external forces.

AI summary

This application provides a detection assembly, including a lead electrode and a conductive terminal. The conductive terminal has a first terminal end and a second terminal end, with the first terminal end having a first end and the second terminal end having a second end. Along the extension direction of the conductive terminal, the lead electrode and the first terminal end are on the same side of the second tip, and the lead electrode and the second terminal end are on the same side of the first tip; or, the lead electrode and the second terminal end are on different sides of the first tip, and the lead electrode is perpendicular to the extension direction of the conductive terminal. This can reduce deformation of the lead electrode caused by external forces.
