Problems solved by technology

The flexible position sensor (position switch) in the prior art can only detect the displacement signal of the top in a specific direction (perpendicular to the overcoat 3), and in some usage occasions, it can detect the displacement signal of some variable directions. The designer Have to choose multiple sensors or complex follow-up system to achieve the above purpose

Abstract

The invention provides a flexible non-directional contact-type sensor, which belongs to the technical field of a sensor. The linear flexible non-directional contact-type sensor comprises a first flexible contact terminal (1), a second flexible contact terminal (2) and an elastic insulation hose (3), wherein the first flexible contact terminal (1) and the second flexible contact terminal (2) are isolated to each other and combined with the inner wall of the hose (3) in a spiral way along the axial direction of the hose (3). By adopting the flexible non-directional contact-type sensor, a displacement signal in any direction within a given angular range can be detected, the installation and application range of the flexible sensor can be greatly enlarged, the requirement for the shape and position precision of the installation surface is low, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a flexible non-directional contact sensor, which belongs to the technical field of sensors. Background technique [0002] Figure 1A It is a schematic diagram of the structure of the flexible sensor provided by the prior art without external force. As shown in Figure 1, the flexible sensor in the prior art includes a flexible contact terminal 1, a flexible contact terminal 2, a jacket 3, a signal line 4 and a signal line 5, the flexible contact terminal 1 is made of a flexible conductor material, and it is electrically connected to the signal line 4; the flexible contact terminal 2 is made of a flexible conductor material, and it is electrically connected to the signal line 5; the outer jacket 3 is Made of elastic insulating material, the lower part is flat and the upper part is hemispherical. The flexible contact terminal 1 is arranged on the upper part of the jacket 3 , and the flexible contact terminal 2 is arranged on the l...
