Description

Technical Field

[0001] The utility model relates to the technical field of current sensors, in particular to a discrete current sensor. Background Art

[0002] A discrete current sensor is an electronic device used to measure current. The working principle of a discrete current sensor is usually based on electromagnetic induction, Hall effect, or fluxgate technology.

[0003] After searching, it was found that the Chinese patent application number 201720342725.8 discloses "a discrete current sensor, which includes a shielding cover for collecting current in a copper busbar to form a magnetic field and a main control board for detecting changes in the magnetic flux of the magnetic field; the shielding cover is formed with a receiving groove; the main control board has a Hall sensor chip, and the main control board is located in the receiving groove of the shielding cover, so that the Hall sensor chip is located in the receiving groove; the main control board and the plane where the bottom wall of the receiving groove is located form an angle of 30°-150°". However, when the above-mentioned discrete current sensor is used, the position of the discrete current sensor is fixed after the discrete current sensor is installed. When the discrete current sensor is installed in a distribution box, due to the complex wiring in the distribution box, the installed discrete current sensor will block the normal laying of the wiring, and the discrete current sensor needs to be removed and reinstalled, which not only affects the wiring efficiency, but also causes the discrete current sensor to stop. Therefore, in order to solve such problems, a discrete current sensor is proposed. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6 A discrete current sensor includes a mounting bar 1 and a discrete current sensor body 11. A guide rail 3 is installed on the top of the mounting bar 1, a slider 4 is slidably installed on the guide rail 3, a mounting plate 7 is installed on the top of the slider 4, and a locking bolt 8 is inserted into the mounting plate 7 and the slider 4. The bottom end of the locking bolt 8 abuts against the top of the guide rail 3. A heat dissipation copper plate 9 is rotatably installed on the top of the mounting plate 7. The discrete current sensor body 11 is installed on the top of the heat dissipation copper plate 9.

[0025] As a technical optimization solution of the present invention, a sliding ring 13 is installed at the bottom of the heat dissipation copper plate 9, and rubber rings 14 are provided on the inner and outer walls of the sliding ring 13. An annular groove 12 is provided on the top of the mounting plate 7. The sliding ring 13 and the two rubber rings 14 are both slidably installed in the annular groove 12, and the rubber rings 14 on the inner and outer walls of the sliding ring 13 are respectively in contact with the two inner walls of the annular groove 12, and the friction force between the rubber ring 14 and the annular groove 12 is greater than the gravity of the discrete current sensor body 11. The top of the heat dissipation copper plate 9 is in contact with the bottom of the discrete current sensor body 11. The heat dissipation copper plate 9 can be used to absorb the heat generated by the discrete current sensor body 11 during operation, thereby assisting the discrete current sensor body 11 in performing rapid heat dissipation processing.

[0026] As a technical optimization solution of the present invention, a limit frame 10 is installed on the top of the heat dissipation copper plate 9, and the discrete current sensor body 11 is installed in the limit frame 10, and the bottom of the discrete current sensor body 11 is in contact with the top of the heat dissipation copper plate 9.

[0027] As a technical optimization solution of the present invention, a support plate 6 is installed on the top of the slider 4, and the mounting plate 7 is installed on the top of the support plate 6. The support plate 6 can facilitate the connection between the mounting plate 7 and the slider 4.

[0028] As a technical optimization solution of the present invention, through holes are provided on the top of the mounting plate 7 and the top of the slider 4 , and internal threads matching the external threads of the locking bolt 8 are provided in both through holes.

[0029] As a technical optimization solution of the present invention, limit blocks 5 are installed at both ends of the guide rail 3. The limit blocks 5 are installed on the top of the mounting bar 1. The limit blocks 5 can limit the slider 4 to prevent the slider 4 from detaching from the guide rail 3.

[0030] As a technical optimization solution of the present invention, a rubber layer is provided on the inner wall of the limit frame 10, the outer wall of the discrete current sensor body 11 is in contact with the rubber layer, and two groups of mounting holes 2 are symmetrically opened on the top of the mounting bar 1, which can facilitate the installation and fixation of the mounting bar 1.

[0031] When the present invention is in use, the device can be installed in the distribution box through the mounting hole 2 on the mounting bar 1. When the discrete current sensor body 11 needs to be installed, it is only necessary to insert the bottom end of the discrete current sensor body 11 into the limit frame 10 to complete the installation of the discrete current sensor body 11. It can quickly and conveniently complete the installation of the discrete current sensor body 11. The rubber layer on the inner wall of the limit frame 10 is used to increase the friction between the limit frame 10 and the discrete current sensor body 11. The discrete current sensor body 11 can be installed in the limit frame 10 to quickly complete the installation of the discrete current sensor body 11.

[0032] When the position of the discrete current sensor body 11 needs to be adjusted, the locking bolt 8 can be disengaged so that the bottom end of the locking bolt 8 is out of contact with the top of the guide rail 3. At this time, the slider 4 is pushed to slide on the guide rail 3 to adjust the position of the mounting plate 7. The position adjustment of the discrete current sensor body 11 can be completed without disassembling the discrete current sensor body 11. After the position adjustment of the discrete current sensor body 11 is completed, the locking bolt 8 can be tightened again so that the bottom end of the locking bolt 8 abuts against the top of the guide rail 3, so that the discrete current sensor body 11 stays in the corresponding position, completing the position adjustment of the discrete current sensor body 11; and when the angle of the discrete current sensor body 11 needs to be adjusted, it is only necessary to rotate the discrete current sensor body 11. The rotation of the vertical current sensor body 11 drives the limit frame 10 to rotate, and the rotation of the limit frame 10 can drive the heat dissipation copper plate 9 to rotate. The rotation of the heat dissipation copper plate 9 drives the sliding ring 13 to rotate in the annular groove 12 to adjust the angle of the discrete current sensor body 11. By using the rubber ring 14 on the inner and outer walls of the sliding ring 13, the friction between the sliding ring 13 and the annular groove 12 can be made greater than the gravity of the discrete current sensor body 11, so that the discrete current sensor body 11 can stay in the corresponding position after the rotation is completed, which is convenient for adjusting the angle of the discrete current sensor body 11. It does not need to disassemble the discrete current sensor body 11 to adjust the position and angle of the discrete current sensor body 11, which facilitates the laying of lines in the distribution box and improves the convenience of using the device.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
