Description

Technical Field

[0001] The utility model relates to the technical field related to sensors, and more specifically to a wiring device for multifunctional eddy current sensor detection. Background Art

[0002] After the existing eddy current sensor probe is fixed to the peripheral equipment by bolts on the outer surface, the sensing direction of the eddy current sensor probe cannot be adjusted, and most of the probes are fixed to the eddy current sensor body, which makes the probe easily hit during transportation and use and easily causes damage to the probe.

[0003] An existing patent for an eddy current sensor probe, with the patent authorization number CN 219776619 U, is provided with a rotating ball. After the sensor body is fixed to the required position by bolts, the user can loosen the hexagon socket screw in the thread hole by a tool to loosen the rotating ball and the slide groove, so that the probe and the probe cover can be rotated along the slide groove to adjust the angle by the rotating ball. When the probe is adjusted to a suitable angle, the hexagon socket screw in the thread hole and the rotating ball are fixed to fix the angle of the probe, so that the eddy current sensor probe can adjust the angle of the probe as needed.

[0004] However, when the probe part of the sensor in patent authorization number CN 219776619 U is connected to the preamplifier through an extension line, the part where the probe part and the extension line are connected is prone to poor contact, which can easily lead to unstable signal transmission.
