[0002] The safety standards for current sensors are becoming increasingly stringent, requiring sensors to be highly safe during installation and use to prevent accidents. The design concept of the open-close current sensor is to solve the inconvenience of traditional sensors in installation and maintenance. Through the open-close design, the sensor can be installed and replaced without interrupting the circuit, greatly improving efficiency and safety. Modern current sensors are not just a simple measuring tool, but are developing in the direction of integration and intelligence. They can be seamlessly connected with the control system to achieve real-time monitoring and analysis of data.

[0003] In the existing technology, most open-and-close sensors are set up in the most common opening and closing manner. Therefore, when encountering more or thicker wires to be clamped, there is a high possibility that the clamping will not be firm or cannot be clamped at all during the clamping process. Therefore, it does not meet the existing needs. In this regard, we propose an open-and-close current sensor that is easy to install. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: This example aims to solve the problem that most open and close sensors in the prior art are set up in the most common opening and closing manner. When there are many or thicker wires to clamp, there is a high possibility of loose clamping or even failure to clamp during the clamping process. Figures 1-6A retractable current sensor that is easy to install includes an upper shell 110, a fixing hole 120 is provided on the side of the upper shell 110, the middle of the upper shell 110 is connected to the lower shell 160 by a snap assembly 320, the upper shell 110 and the lower shell 160 are hinged by a rotating shaft 150, a clamping hole 130 is provided in the middle of the upper shell 110 and the lower shell 160, a clamping assembly 330 is provided on the side of the clamping hole 130, and an insertion slot 140 is provided on the side of the upper shell 110.

[0025] A card slot 230 is opened in the middle of the lower shell 160, and a card slot 240 is connected to the side of the card slot 230. The card assembly 320 includes a card frame 250 installed in the middle of the upper shell 110, and an installation frame 260 is installed in the middle of the card frame 250. A limiting slot 270 is opened in the middle of the installation frame 260, and a limiting spring 310 is set in the middle of the limiting slot 270.

[0026] When the device is in use, the wires are first plugged into the plug holes, and then the wires are clamped through the clamping holes 130. During the clamping process, wires of different specifications or different quantities can be clamped by the setting of the clamping assembly 330. Before clamping, the upper shell 110 is bent upward, and the upper shell 110 will rotate through the setting of the rotating shaft 150. After the wires are placed, the upper shell 110 and the lower shell 160 are snap-connected.

[0027] When the upper shell 110 and the lower shell 160 are engaged and connected, the engaging frame 250 and the engaging block 280 in the engaging assembly 320 are engaged with the engaging slot 230 and the engaging slot 240 respectively. During the engaging process, when the upper shell 110 is subjected to force, the engaging block 280 will squeeze the limit spring 310 to expand and contract. The side of the engaging block 280 is chamfered, so when the engaging block 280 is engaged, the engaging block 280 is as convenient as possible to engage and dislocate. When clamping wires of different specifications, if the number is large or thicker, the clamping plate 180 will be pushed, which will squeeze the extrusion spring 220 and pull the connecting plate 170, so that the diameter of the clamping hole 130 becomes larger, and more or thicker wires can be clamped.

[0028] In this embodiment: through the snap connection between the upper shell 110 and the lower shell 160 and the hinged setting of the rotating shaft 150, the sensor can be quickly opened and closed, which is convenient for installation and maintenance. Through the setting of the fixing hole 120 and the clamping assembly 330, the sensor can be firmly fixed on the wire or other measurement object after installation to ensure the accuracy of the measurement. Through the setting of the snap assembly 320 and the clamping assembly 330, the sensor can be tightly fixed in the closed state, avoiding potential safety hazards caused by looseness. Due to the setting of the clamping assembly 330 and the snap assembly 320, the sensor can adapt to wires of different diameters, thereby improving its applicability.

[0029] Example 2: This example aims to solve the problem of inconvenient engagement of the open-close sensor. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1-6 The side of the limit spring 310 is fixedly connected to the push plate 300 , the side of the push plate 300 is fixedly connected to the fixed block 290 , and the side of the fixed block 290 is fixedly connected to the clamping block 280 .

[0030] The snap-fitting frame 250 is snap-fitted to the snap-fitting slot 230, and the snap-fitting block 280 is snap-fitted to the snap-fitting slot 240. The snap-fitting frame 250 and the snap-fitting block 280 are both made of rubber. The clamping assembly 330 includes a fixed frame 190 opened in the middle of the upper shell 110 and the lower shell 160. An extrusion groove 200 is opened in the middle of the fixed frame 190, and an extrusion spring 220 is provided in the middle of the extrusion groove 200.

[0031] A connecting block 210 is inserted into the middle of the extrusion spring 220 , and the connecting block 210 is fixedly mounted on the side of the clamping plate 180 , and a connecting plate 170 is inserted into the side of the clamping plate 180 . A plurality of clamping assemblies 330 are arranged in a circular array.

[0032] In this embodiment: by setting the rubber material of the locking frame 250 and the clamping block 280, the sensor has a good feel and wear resistance during operation, and also reduces the noise during installation. By setting the extrusion spring 220 and the connecting spring, the clamping force can be adaptively adjusted, which is convenient for maintenance and replacement. By setting the annular array of the connecting plate 170, the clamping plate 180, the fixing frame 190, the extrusion spring 220 and the connecting spring, the sensor is more compact in structure and is also convenient for mass production and assembly. By setting the limiting groove 270 and the limiting spring 310, it can prevent the sensor from damaging the wire due to excessive closure to a certain extent.

[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
