[0002] Electrical switches usually control the opening and closing of circuits. Commonly used electrical switches mainly include circuit breakers. Circuit breakers are mainly used to monitor and control the current in abnormal circuits. They are mainly used in electrical boxes and low-voltage metering boxes. It is usually necessary to set mounting brackets or mounting beams in the electrical boxes and low-voltage metering boxes to install the circuit breakers. A certain distance is usually required between the circuit breakers arranged on the same floor to ensure the heat dissipation requirements of the circuit breakers and avoid entanglement of the lines. To address this problem, a Chinese patent application with application publication number CN117832023A and application publication date 2024.04.05 discloses a circuit breaker mounting bracket, the technical solution of which is to clamp the circuit breaker with a clamping block, connect the clamping block to a slider, and set a first slide groove on the mounting plate to make the slider slidably connected to the first slide groove, and drive the clamped circuit breaker to move horizontally by the horizontal movement of the slider along the first slide groove, thereby creating a distance between the circuit breakers.

[0003] However, in the above scheme, the slider cannot be positioned between the slider and the first slide groove, and the circuit breaker connected to the slider cannot be positioned either. Then, when the electrical box vibrates or is moved, the slider will slide in the first slide groove and drive the circuit breaker to shift, which will change the installation position of the circuit breaker and cannot meet the positioning and installation requirements of the circuit breaker.

[0027] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0028] Embodiments of the electrical switch mounting beam assembly of the present invention: In the prior art, the circuit breaker installation position and the spacing between adjacent circuit breakers are adjusted by connecting the circuit breaker to the mounting frame and then controlling the mounting frame to move horizontally. However, the circuit breaker cannot be positioned at the designated position after reaching the designated position. In particular, when the external electrical box is vibrated or moved, the internal circuit breaker is easily displaced. In view of the above problems, the present invention proposes an electrical switch mounting beam assembly and an electrical box. The assembly is divided into two parts, the first part can be fixedly mounted with the electrical box, the second part has a mounting hole 8 and the circuit breaker can be connected to the mounting hole 8. When the circuit breaker is not connected to the mounting hole 8, the second part can move horizontally in the first part to adjust the position of the mounting hole 8 until it reaches the designated installation position. Then, the circuit breaker 2 is connected to the mounting hole 8. At this time, the second part will be clamped and positioned with the first part, and the second part cannot move horizontally in the first part. This can avoid displacement of the circuit breaker and fix the position of the circuit breaker.

[0029] See also Figures 1 to 3As a basic embodiment of the present invention, the electrical switch mounting beam assembly of the present invention includes a mounting crossbeam 1, which can be used as a connecting piece between the electrical switch and the electrical box to fix the electrical switch in the electrical box. The mounting crossbeam 1 includes a bottom plate 3, which extends laterally. An upper card plate 4 and a lower card plate 10 are respectively arranged on the upper edge and the lower edge of the bottom plate 3. The lengths of the upper card plate 4 and the lower card plate 10 are equal to the length of the bottom plate 3. A card plate 6 is arranged between the upper card plate 4 and the lower card plate 10. The card plate 6 can move horizontally between the upper card plate 4 and the lower card plate 10 along the length direction of the bottom plate 3. The upper card plate 4 and the lower card plate 10 can As a moving track of the positioning plate 6, the positioning plate 6 is provided with a mounting hole 8, and the electrical switch can be installed through the mounting hole 8. Here, the electrical switch is set as the circuit breaker 2. When the positioning plate 6 moves horizontally, the position of the mounting hole 8 on the positioning plate 6 can be adjusted, and then the installation position of the circuit breaker 2 can be adjusted. When the positioning plate 6 moves to the specified installation position, the circuit breaker 2 is connected to the mounting hole 8. At this time, the upper and lower ends of the positioning plate 6 can be clamped with the upper clamping plate 4 and the lower clamping plate 10 to be positioned. At the same time, the upper clamping plate 4 and the lower clamping plate 10 can form a stop fit with the back of the circuit breaker 2, so that the installation and positioning of the circuit breaker 2 can be realized.

[0030] As a preferred embodiment of the present invention, the upper clamping plate 4 and the lower clamping plate 10 are arranged relatively to each other and have the same structure. They are both "L"-shaped clamping eaves. The clamping eaves include a pressing portion 12. The clamping eaves of the "L"-shaped structure are provided with an elastic bending portion 11 at the corner. One end of the elastic bending portion 11 is connected to the pressing portion 12. The upper and lower ends of the clamping plate 6 can form a stop fit and clamp with the elastic bending portion 11 on the upper clamping plate 4 and the lower clamping plate 10. At the same time, the pressing portion 12 can prevent the upper and lower ends of the clamping plate 6 from separating from the elastic bending portion 11. When the upper and lower ends of the clamping plate 6 are clamped with the elastic bending portion 11 on the corresponding side, the pressing portion 12 will provide reverse pressure on the upper and lower ends of the clamping plate 6, so that the clamping plate 6 is clamped tighter with the upper and lower clamping plates, and the pressing portion 12 can form a pressure against the back of the installed circuit breaker 2 to prevent the circuit breaker 2 from shaking vertically.

The card plate 6 is an arc-shaped plate, and its outer arc surface is convex in the direction close to the bottom plate. The card plate 6 has good toughness and can be deformed to a certain extent when subjected to force. When a certain point of the card plate 6 is subjected to force and deformed in the direction of the force, the upper and lower ends of the card plate 6 will be deformed in the direction opposite to the force. When the inner arc surface of the locking plate 6 is subjected to force and the force direction points to the outer arc surface, the upper and lower ends of the locking plate 6 will deform in the direction away from the outer arc surface, so that the locking plate 6 and the elastic bending part are clamped, thereby realizing the clamping and positioning of the locking plate 6 and the mounting beam 1. In other embodiments, the locking plate 6 can also be set as a straight plate or a plate of other shapes, as long as the force point and the two ends of the locking plate 6 are deformed in the opposite direction when subjected to force, and finally the locking plate 6 and the mounting beam 1 are clamped and positioned.

The inner wall of the mounting hole 8 is provided with an internal thread, and a screw 9 is installed in the mounting hole 8. The screw 9 can enter from between the upper clamping plate 4 and the lower clamping plate 10 and be screwed into the mounting hole 8. In the process of screwing the screw 9 into the mounting hole 8, the middle part of the positioning plate 6 will be deformed by force, so that the upper and lower ends of the positioning plate 6 are clamped with the elastic bending parts 11 of the upper and lower clamping plates. In other embodiments, the screw sleeve 7 can also be arranged at other positions on the inner arc surface of the positioning plate 6 and two screw sleeves 7 need to be symmetrically arranged to ensure that the positioning plate 6 is subjected to uniform force, so as to ensure that the upper and lower ends of the positioning plate 6 can be deformed and clamped with the corresponding upper and lower clamping plates.

[0033] As a preferred embodiment of the present invention, the positioning plate 6 can be set to one or more. The specific number can be determined according to the number of circuit breakers 2 or other electrical switches to be installed. When the positioning plate 6 is set to multiple, the multiple positioning plates 6 are horizontally arranged between the upper card plate 4 and the lower card plate 10 along the length direction of the base plate 3.

[0034] As a preferred embodiment of the present invention, the base plate 3 is integrally formed with the upper card plate 4 and the lower card plate 10 to obtain a mounting beam 1, and waist-shaped mounting openings 5 ​​are symmetrically arranged at both ends of the base plate 3, and the base plate 3 can be fixed to the inner wall of the electrical box through the waist-shaped mounting openings 5. In other embodiments, the upper card plate 4 and the lower card plate 10 can also be connected to the base plate 3 by welding, riveting or other connecting parts, as long as it can be ensured that there is no relative displacement between the upper card plate 4 and the lower card plate 10 and the base plate 3, and they can be firmly connected together.

[0035] See also Figures 4 to 5The method for using the electrical switch mounting beam assembly of the present invention is as follows: first, the mounting crossbeam 1 is fixedly connected to the wall plate, beam body or stand in the electrical box through the waist-shaped mounting opening 5, and then the positioning plate 6 is horizontally moved to make the positioning plate 6 reach the installation position of the corresponding circuit breaker 2, and then the circuit breaker 2 is aligned with the mounting hole 8 on the corresponding positioning plate 6, so that the screw 9 is screwed with the circuit breaker 2 and the mounting hole 8 in turn, so that the circuit breaker 2 and the mounting hole 8 are positioned. At the same time, during the process of screwing in the screw 9, the positioning plate 6 is deformed by force, and the upper and lower ends of the positioning plate 6 are clamped with the upper clamping plate 4 and the lower clamping plate 10 respectively, thereby realizing the connection and positioning of the positioning plate 6 and the mounting crossbeam 1. At this time, the positioning plate 6 cannot move horizontally, and the circuit breaker 2 connected thereto cannot move horizontally either, that is, the installation and positioning of the circuit breaker 2 are realized.
