Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, and more particularly to a circuit breaker for power protection. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and can close, carry, and interrupt current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is relatively blurred. Generally, circuit breakers above 3kV are referred to as high-voltage electrical appliances.

[0003] Traditionally, when circuit breakers are installed inside electrical boxes, they are usually connected directly to the mounting surface by screwing them on. When there are many circuit breakers installed, it is very troublesome for personnel to repeatedly install and remove them. In addition, when installing circuit breakers of different sizes, the staff also need to select the corresponding screws according to the size of the screw holes on the terminal block, which is very troublesome for personnel and reduces the efficiency of circuit breaker installation and removal.

[0004] Furthermore, in the existing design, the circuit breaker is not equipped with a protective mechanism around its perimeter. Under the influence of external impact, the control part of the circuit breaker is easily damaged. In addition, a large amount of dust will accumulate on the surface of the circuit breaker, so cleaning is required. This wastes time and may cause the switch to be turned off, resulting in a power outage and affecting the normal use of the power supply. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit breaker for power protection.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] like Figure 1-8 The circuit breaker for power protection shown includes a first fixing plate 8 and a circuit breaker body 16. Two symmetrically arranged connectors 9 are mounted on the surface of the first fixing plate 8 using screws. The two connectors 9 are bent, and each has a screw hole 10 on its surface. When fixing the first fixing plate 8 to the inner wall of the electrical box, one end of each connector 9 is first brought into contact with the inner wall of the electrical box. Then, screws are passed through the screw holes 10 and threaded into the inner wall of the electrical box to fix the position of the first fixing plate 8, thereby improving the stability of the circuit breaker placed inside the electrical box.

[0028] A mounting plate 3 is provided on one side of the circuit breaker body 16. The mounting plate 3 and the circuit breaker body 16 are connected by a movable mechanism. The movable mechanism includes a long strip plate 19. The long strip plate 19 is installed on the surface of the circuit breaker body 16 by screws. A dovetail groove 21 is opened on the surface of the long strip plate 19. A dovetail block 29 is placed inside the dovetail groove 21. A first fixing block 17 is installed on the surface of the dovetail block 29 by screws. A bearing 36 is fixedly embedded on the surface of the first fixing block 17. An installation rod 18 is tightly installed on the inner ring of the bearing 36. One end of the installation rod 18 is installed on the surface of the mounting plate 3 by screws. A plurality of third screw holes 28 are arranged at equal angles on the surface of the first fixing block 17. A ring 27 is fixedly sleeved on the surface of the installation rod 18. A second screw hole 24 is opened on the surface of the ring 27, corresponding to the position of the third screw hole 28. A second stud 25 is threaded between the second screw hole 24 and the third screw hole 28. Since the electrical box contains more than just the circuit breaker, the angle of the circuit breaker can be adjusted according to the arrangement of the components within the box to meet installation space requirements. During adjustment, the second stud 25 is rotated, causing it to thread within the second screw hole 24 and the third screw hole 28. After one end of the second stud 25 is removed from the third screw hole 28, a force can be applied to the circuit breaker. This force then acts on the elongated plate 19, which rotates within the first fixing block 17 via the bearing 36, facilitating the adjustment of the circuit breaker's angle and its position. After adjustment, the second stud 25 can be re-threaded into the third screw hole 28 to connect and fix the first fixing block 17 and the ring 27, thereby improving the stability of the circuit breaker's position. When connecting the circuit breaker and the first fixing block 17, simply move the circuit breaker and slide the dovetail groove 21 onto the surface of the dovetail block 29. After the dovetail groove 21 and the dovetail block 29 are in contact and engaged, the connection stability between the circuit breaker and the first fixing block 17 is improved.

[0029] A fourth screw hole 30 is formed on the surface of the dovetail groove 21. A mounting block 20 is placed inside the dovetail groove 21. A first screw hole 22, corresponding to the position of the fourth screw hole 30, is formed on the surface of the mounting block 20. A first stud 23 is threaded between the first screw hole 22 and the fourth screw hole 30. To further improve the stability of the circuit breaker and the first fixing block 17, the mounting block 20 is simply placed inside the dovetail groove 21. After the positions of the first screw hole 22 and the fourth screw hole 30 are aligned, the first stud 23 can be threaded between the first screw hole 22 and the fourth screw hole 30 to improve the stability of the mounting block 20 inside the dovetail groove 21. After the position of the mounting block 20 is fixed, one end of the mounting block 20 contacts one end of the dovetail block 29, while the other end of the mounting block 20 contacts the inside of the dovetail groove 21, which serves to limit the position of the dovetail block 29, further improving the stability of the connection between the circuit breaker and the first fixing block 17.

[0030] A protective mechanism is provided between the mounting plate 3 and the circuit breaker body 16. The protective mechanism includes a protective shell 1 and a groove 13. The protective shell 1 is fitted around the circuit breaker body 16. The groove 13 is located at one end of the mounting plate 3. A fixed shaft 14 is installed between two symmetrical sides inside the groove 13 via screws. A movable block 2 is movably fitted onto the surface of the fixed shaft 14. One end of the movable block 2 is installed on the surface of the protective shell 1 via screws. A positioning mechanism is provided between the other end of the protective shell 1 and the mounting plate 3. The positioning mechanism includes a magnetic block 11 and a metal block 12. The magnetic block 11 is installed on the side of the mounting plate 3 via screws, and the metal block 12 is installed on the side of the protective shell 1 via screws. The magnetic block 11 and the metal block 12 are connected by magnetic attraction. The protective shell 1, in cooperation with the mounting plate 3, provides protection around the circuit breaker, thereby improving the safety of the circuit breaker's location. When the circuit breaker needs to be operated, simply apply force to the protective housing 1. The protective housing 1 will rotate after being subjected to force. At this time, the metal block 12 will separate from the magnet block 11. Simultaneously, the protective housing 1 will drive the movable block 2 to rotate on the surface of the fixed shaft 14, making it easier to rotate the protective housing 1 above the mounting plate 3 for convenient operation of the circuit breaker.

[0031] Mounting plate 3 is located between the first fixing plate 8 and the circuit breaker body 16. Both ends of mounting plate 3 are screwed onto pipe fittings 4, with corresponding positions between the two fittings. A first mounting rod 5 is inserted into the interior of each fitting 4. A second fixing plate 26 is screwed onto one end of each first mounting rod 5. A tension spring 15 is screwed onto the surface of the two second fixing plates 26. A limiting mechanism is fitted onto the surface of the tension spring 15, including two stops 31. The two stops 31 are screwed onto the surface of mounting plate 3, located on both sides of the tension spring 15. A baffle 35 is located between the two stops 31, on one side of the tension spring 15. During the stretching or contraction of the tension spring 15, this mechanism prevents positional displacement and improves the stability of the connection between the two pressure plates 6 and the first fixing plate 8.

[0032] The other ends of the two first mounting rods 5 are each fitted with a pressure plate 6 by screws. The surfaces of the two pressure plates 6 are in contact with the two symmetrical sides of the first fixing plate 8. The surfaces of the two pressure plates 6 are each fitted with a second fixing block 34 by screws. The sides of the two second fixing blocks 34 are in contact with the sides of the first fixing plate 8. When connecting the mounting plate 3 and the first fixing plate 8, the two pressure plates 6 are pulled in opposite directions simultaneously. The two pressure plates 6 pull the two first mounting rods 5 to slide within the two pipe fittings 4, facilitating the pull of the tension spring 15 by the two first mounting rods 5. At this time, the length of the tension spring 15 is extended. When the two pressure plates 6 are in contact with the symmetrical surfaces of the first fixing plate 8, the tension spring 15 pulls the two first mounting rods 5 by its own force. The two first mounting rods 5 pull the two pressure plates into contact with the two symmetrical sides of the first fixing plate 8, thus stabilizing the connection between the mounting plate 3 and the first fixing plate 18.

[0033] The surface of the first fixing plate 8 has multiple elongated holes 7, and fixing rods 32 are inserted into the multiple elongated holes 7. One end of the fixing rods 32 is mounted on the surface of the mounting plate 3 by screws. At least two elongated holes 7 are provided and are arranged symmetrically. The arrangement of the elongated holes 7 and fixing rods 32 is used to prevent the mounting plate 3 from moving in the horizontal position, thereby improving the stability of the mounting plate 3.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
