Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to an easy-to-assemble arc-extinguishing cover. Background Technology

[0002] When the contacts of a circuit breaker open and close, an electric arc is generated due to gas discharge. This arc can cause some damage to the structure of the circuit breaker. Therefore, most circuit breakers are equipped with arc extinguishers.

[0003] However, current arc extinguishers generally use a riveting process to fix the arc extinguishing plate and the arc isolation plate. The riveting process is relatively complex and costly, especially for non-standard arc extinguishers. Therefore, application number 202222291039.6 discloses an arc extinguishing chamber that no longer uses riveting to fix the arc isolation plate and the arc extinguishing plate. Instead, the arc extinguishing plate is installed in the mounting groove. However, this device, which only relies on the friction between the mounting groove and the arc extinguishing plate for fixation, is prone to unstable fixing of the arc extinguishing plate. Therefore, an improvement is needed. Utility Model Content

[0005] This utility model provides the following technical solution: an easy-to-assemble arc-extinguishing cover, including two arc-blocking plates arranged opposite each other, a plurality of arc-extinguishing plates are installed between the arc-blocking plates and distributed at equal vertical distances, and slots distributed at equal vertical distances for accommodating the arc-extinguishing plates are provided on the sides of the two arc-blocking plates that are close to each other, and the slots penetrate the arc-blocking plates laterally. An installation plate is mounted on the side of the arc-extinguishing plate away from the arc-extinguishing plate. The right end of the installation plate is integrally formed with a right baffle that is attached to the right end of each arc-extinguishing plate, and also includes a left baffle that is attached to the left end of each arc-extinguishing plate. The front and rear sides of the left baffle are integrally formed with hook-shaped hook plates. The hook plates and the installation plate are both fixed to the arc-extinguishing plate by bolts.

[0006] Preferably, the arc-blocking plates are further reinforced by cross plates.

[0019] Reference Figures 1-4 According to an embodiment of the present invention, an easy-to-assemble arc-extinguishing cover includes two arc-blocking plates 11 arranged opposite to each other, and a plurality of arc-extinguishing plates 12 are installed between the arc-blocking plates 11 at equal vertical distances, so that the easy-to-assemble arc-extinguishing cover can perform the arc-extinguishing function.

[0020] The two arc-blocking plates 11 are provided with slots 13 that are equally spaced vertically on their sides and are used to accommodate the arc-extinguishing plates 12. The slots 13 extend horizontally through the arc-blocking plates 11.

[0021] In order to lock the arc-extinguishing plate 12 in the left and right position relative to the arc-blocking plate 11, an mounting plate 14 is installed on the side of the arc-extinguishing plate 11 away from the arc-extinguishing plate 12. The right end of the mounting plate 14 is integrally formed with a right baffle 15 attached to the right end of each arc-extinguishing plate 12, and also includes a left baffle 16 attached to the left end of each arc-extinguishing plate 12. The front and rear sides of the left baffle 16 are respectively integrally formed with hook-shaped hook plates 17. The hook plates 17 and the mounting plate 14 are both fixed to the arc-blocking plate 11 by bolts.

[0022] The left baffle 16 and the right baffle 15 can lock the left and right positions of the arc extinguishing plate 12 relative to the arc blocking plate 11, while the slot 13 can limit the up and down positions of the arc extinguishing plate 12, thereby making the arc extinguishing plate 12 completely locked.

[0023] Furthermore, in order to improve the overall strength of the easy-to-assemble arc-extinguishing cover, the arc-blocking plates 11 are reinforced by horizontal plates 18, which are respectively disposed at the upper and lower ends of the arc-blocking plates 11.

[0024] In the second embodiment of the easily assembled arc-extinguishing cover, to further increase the connection strength between the arc-blocking plate 11 and the arc-extinguishing plate 12 and to prevent the arc-blocking plate 11 from shaking, such as... Figure 3 As shown, each of the card slots 13 has an outwardly penetrating groove 19 on its bottom surface, and each of the arc-extinguishing plates 11 is also provided with a card plate 20. The side of the card plate 20 is provided with pressure plates 21 that are equally spaced vertically and inserted into the penetrating groove 19 and pressed against the arc-extinguishing plate 12. It also includes a clamping component for locking the position of the card plate 20.

[0025] In this embodiment, as Figure 4 As shown, the clamping assembly includes a receiving groove 22 disposed in the mounting plate 14 for accommodating the card plate 20, and the back of the card plate 20 is attached to the bottom surface of the receiving groove 22.

[0026] When the worker fixes the mounting plate 14, the mounting plate 14 will press against the clamping plate 20, and the pressure plate 21 will press against the arc extinguishing plate 12, thereby making the arc extinguishing plate 12 more stable.

[0027] In addition, the mounting plate 14 can also be designed to slide left and right on the arc-extinguishing plate 11, so that the receiving groove 22 passes through to the left. After the mounting plate 14 moves to the left, it can press against the clamping plate 20. The left and right positions of the mounting plate 14 are then fixed by the bolts. Through the above settings, the sliding member used to restrict the mounting plate 14 from detaching from the arc-extinguishing plate 12 and the bolts can both make the mounting plate 14 press against the clamping plate 20, thereby increasing the clamping force.

[0028] In order to prevent the mounting plate 14 from hitting the side of the card plate 20 when it moves to the left due to machining tolerances, the bottom surface of the receiving groove 22 is chamfered with respect to the left side surface of the mounting plate 14.

[0029] It should be noted that the horizontal plate 18 can also be fixed by fasteners so that the easy-to-assemble arc extinguishing cover does not require welding or riveting processes. The horizontal plate 18 can also be integrally formed with the arc-blocking plate 11.

[0030] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
