A current sensor fixing device

Abstract

The invention discloses a fixing device of a current sensor. The fixing device of the current sensor comprises a sensor body, and buffer springs are arranged on the upper side and the lower side of the left side wall in the sensor body. The right ends of the two buffer springs are fixedly connected with a base, the right end of the base is provided with the current sensor, and the left end of a sensor frame body is fixedly connected with a middle fixing base. An upper cavity is arranged on the upper portion in the middle fixing base, a lower cavity is arranged on the lower portion in the middle fixing base, and a first deformation joint is arranged in the upper cavity. When the fixing device works, a screw rod rotates in the middle fixing base, a first sleeve and a third sleeve move downwards, a second sleeve and a fourth sleeve move upwards, then the left ends of the deformed first deformation joint and the deformed second deformation joint are placed in a left fixing seat, collisionis avoided, and the buffer spring can maintain the base to be fixed. After using of the fixing device, the screw rod is rotated reversely, the fixing device can be taken out so as to be maintained andchecked, the service life is prolonged, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of fixing devices, in particular to a fixing device for a current sensor. Background technique [0002] The current sensor is a detection device that can feel the information of the measured current, and can transform 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 requirements. transmission, processing, storage, display, recording and control requirements. 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. [0003] According to different measurement principles, current sensors can be mainly divided into shunts, electromagnetic current transformers,...

AI Technical Summary

Problems solved by technology

Traditionally, the installation and fixing of the current sensor is mainly through the tester holding the sensor to place the current sensor on the casing, but it is easy to collide during the operation, resulting in damage to the current sensor, thereby reducing the accuracy of the measurement

In addition, when the tester holds the current sensor and holds it against the sample under test, the measurement accuracy is reduced due to the uneven force between the current sensor and the sample under test, and there is often no buffer device on the current sensor device
