Electrical control current sensor capable of being firmly fixed

Abstract

The invention provides an electrical control current sensor capable of being firmly fixed, relates to the technical field of current sensors, and solves the problems that an existing current sensor is generally installed and applied through a screw fastener, and if an installation part of the current sensor is influenced by external vibration factors, the screw fastener is easy to loosen, and the fastening effect cannot be achieved. The electrical control current sensor capable of being firmly fixed comprises a current sensor body and four sets of plug-in drawing mechanisms, and the four sets of plug-in drawing mechanisms are installed on the side end face of the current sensor body in a sliding mode and close to the four edge corners of the current sensor body respectively. The limiting inserting groove is matched with the limiting block in an inserting mode, when the limiting block is not separated from the limiting inserting groove, the screw fixing piece cannot be rotated by more than 45 degrees, and therefore it can be guaranteed that the screw fixing piece cannot be disengaged from a corresponding installation part due to autorotation.

Description

technical field [0001] The invention belongs to the technical field of current sensors, and more specifically relates to a securely fixed electric control current sensor. Background technique [0002] The current sensor is a detection device that can sense the information of the measured current, and can convert the information sensed by the detection into an electrical signal that meets certain standards or other required forms of information output according to certain rules, so as to meet the Information transmission, processing, storage, display, recording and control requirements. [0003] Current sensors are also called magnetic sensors, which can be used in household appliances, smart grids, electric vehicles, wind power generation, etc. Many magnetic sensors are used in our lives, such as computer hard drives, compasses, and household appliances. [0004] For example, application number: CN202010926185.4 The present invention relates to the field of current sensor t...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a securely fixed electric control current sensor to solve the problem that the existing current sensors are generally installed and applied by screw fasteners, but if the installation part is affected by external vibration factors, the screw Fasteners are prone to looseness, which makes it unable to achieve fastening effect, and when the current sensor is loose, it does not have a reminder function, which leads to the problem that the subsequent current sensor is detached
