Description

Technical Field

[0001] The utility model relates to the technical field of force sensors, in particular to a connecting device for a force sensor. Background Art

[0002] A force sensor is composed of three major parts: one or more elastic bodies that can deform when subjected to force, a bridge circuit consisting of a resistance strain gauge that can sense this deformation, an adhesive that can fix the resistance strain gauge on the elastic body and can transmit the strain, and a sealant that protects the electronic circuit. When subjected to external force, the strain gauge attached to the elastic body will deform, causing a change in resistance. The resistance change causes the Wheatstone bridge to lose balance and output an electrical signal that changes linearly proportional to the external force.

[0003] The existing force sensor is not convenient for adjusting the installation height during installation, and thus cannot limit the contact distance between the force sensor and the object being measured. Therefore, we propose a connection device for the force sensor. Utility Model Content
