Inductance type displacement sensor assembly

Abstract

The utility model discloses an inductive displacement sensor assembly, which comprises a shell, an iron core assembly and a PCB (Printed Circuit Board), the iron core assembly comprises an iron core, a framework and a coil, the iron core is composed of a yoke part and a pair of tooth parts arranged on the same side of the yoke part, the framework is arranged on the tooth parts in a sleeving mode, and the coil is wound around the framework; the shell is in a circular ring shape, the PCB and the iron core assemblies arranged in the circumferential direction are fixedly arranged in the shell, the tooth portions of the iron cores right face the circle center, and the coil is connected with the PCB. The internal iron core is of a partitioned structure, so that iron core materials can be saved, the weight of the sensor is reduced, and the manufacturing cost of the sensor is reduced; the modular framework is small in size, integrally-formed large-batch production is facilitated, the winding difficulty is reduced, and the winding length is saved; according to the arrangement mode of the iron core assemblies in the shell, radial, axial and axial-radial integrated inductive displacement sensors can be formed. The device is simple in structure, convenient to use, flexible to assemble, high in integration level, good in reliability, high in practicability and wide in applicability.
