Problems solved by technology
Since the eddy current detection is based on electromagnetic induction, the eddy current is induced in the metal conductor through the magnetic field of the detection coil, and the reaction magnetic field generated by the eddy current changes the impedance of the detection coil, and the metal conductor is judged according to the impedance change of the detection coil The existing problem is that due to many factors affecting the change of detection coil impedance, it will bring interference information to the detection results, especially the connector between the detection coil and the signal processor. In order to avoid and reduce interference information It is very important to design a connector socket that meets the eddy current test.

The invention discloses a connector socket used a for eddy current testing device. The connector socket comprises a first medium body, an inner conductor, a first outer conductor, a clamping ring, a second medium body and a second outer conductor. The inner conductor is inserted inside the first medium body, the first medium body is inserted inside the first outer conductor, and the clamping ring is disposed in the first outer conductor. The second medium body is sleeved on an outer ring of the first outer conductor, and is in thread engagement with the same. The second outer conductor is sleeved on outer ring of the second medium body, and is thread engagement with the same. The first outer conductor and the second outer conductor are connected through wires. The connector socket can really reflect that a counter magnetic field generated by eddy current changes resistant of a tested coil, and interference information is effectively prevented and reduced. The connector socket is advantaged by simple structure, convenient usage, and accurate detection.
Description
technical field [0001] The invention relates to a socket in the technical field of electrical connectors, in particular to a connector socket used for eddy current detection equipment. Background technique [0002] Eddy current testing is a general and economical testing method in non-destructive testing technology. Compared with other non-destructive testing methods, it is widely used because of its abnormal sensitivity in detecting tiny cracks in metal conductors and defects on metal surfaces. Since eddy current detection is based on electromagnetic induction, eddy current is induced in the metal conductor through the magnetic field of the detection coil, and the reaction magnetic field generated by the eddy current changes the impedance of the detection coil, and the metal conductor is judged according to the impedance change of the detection coil The existing problem is that due to many factors affecting the change of detection coil impedance, it will bring interfere...
