Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker technology, specifically relating to a sealing structure for a molded case circuit breaker. Background Technology

[0002] During the opening and closing of a circuit breaker, a gap is created between the handle and the faceplate, which can easily allow dust to enter and cause interference from other external components. To solve this problem, a plate-shaped handle baffle is usually installed on the handle to block the gap.

[0003] Chinese patent CN200710105500.1 discloses a circuit breaker. The circuit breaker functional component, including an operating handle, is mounted on a main body housing composed of a casing and a cover. The operating handle has a grip portion that stands upright on the center of an edge-shaped base that is connected to the top of a rocker handle rod. The grip portion passes through a handle window frame opening in the main body housing cover and protrudes outwards. A sheet-like handle baffle is fitted onto the base, acting as a blocking element to seal the gap between the base and the handle window frame. The handle baffle extends forward from the front edge of the base opposite the handle window frame and backward from the rear edge in the ON and OFF positions of the operating handle, respectively, sealing the gap. In this structure, the gap is effectively sealed during the opening and closing of the handle. However, the baffle is directly mounted on the handle and moves in a circular motion, limiting the space occupied by the mechanism. As a single part fitted onto the handle, the baffle is easily scattered and lost during assembly and disassembly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing sealing structure between the handle and the cover, which occupies space in the mechanism components and makes the parts easy to fall off and be lost. It provides a sealing structure for a molded case circuit breaker. The entire sealing structure adopts a sliding component form, which not only reduces the space occupied, but also avoids the parts falling off and being lost.

[0034] Example

[0035] The existing sealing structure between the handle and the faceplate occupies space in the mechanism components, making parts prone to scattering and loss. To solve this problem, as shown in the attached... Figures 1-9 As shown in the attached figure, this embodiment provides a sealing structure for a molded case circuit breaker. Figure 1 and 2 As shown, it includes a face cover 1, and a baffle 2 is fitted onto the inner side of the face cover 1. In this embodiment, as shown in the attached diagram... Figure 1 and attached Figure 4 As shown, a card holder 1b is provided on the inner side of the cover 1, as illustrated in the attached diagram. Figure 5 As shown, a hook 2b is provided on the baffle 2 at a position corresponding to the card holder 1b, and the hook 2b is attached to the card holder 1b. A connection as shown in the attached diagram is provided between the cover 1 and the baffle 2. Figure 3 The slide plate 4 is mounted in space 3 and can slide within it. The slide plate 4, mounted in space 3, can slide horizontally under the influence of the handle 5.

[0036] The faceplate 1 has an opening 11 for the handle 5 to operate. The baffle 2 is mounted on the inner side of the faceplate 1. The baffle 2 has a second opening 21 for the handle 5 to operate, and this second opening 21 is larger than the operating area of ​​the handle 5. (See attached image.) Figure 6As shown, the slide plate 4 has an opening 41 that matches the size of the handle 5. The slide plate 4 is installed in the space 3 and can slide under the action of the handle 5. More specifically, the slide plate 4 has a toggle protrusion 4b on the side facing the baffle 2. The baffle 2 has a stroke hole 2a at a corresponding position to the toggle protrusion 4b, and the toggle protrusion 4b is located in the stroke hole 2a. When the handle is turned, the handle 5 moves the slide plate 4 within the space 3 of the cover 1. The space 3 limits the movement of the slide plate 4. Simultaneously, the toggle protrusion 4b slides within the stroke hole 2a, further limiting the movement of the slide plate 4. Furthermore, the toggle protrusion 4b also prevents the slide plate 4 from being installed incorrectly. If installed backwards, the protrusion 4b abuts against the inner side of the cover 1, preventing the baffle 2 from being installed on the cover 1. If installed upside down, the protrusion 4b abuts against the side of the baffle 2 away from the stroke hole 2a, preventing the baffle 2 from being installed on the cover 1. Furthermore, arrows can be marked on the inner side of the cover 1, and arrows can also be marked on the side of the slide plate 4 facing away from the inner side of the cover 1. When the two arrows are in the same direction, it is the correct installation method, which further achieves the effect of preventing mistakes.

[0037] When the handle is turned, the outer edge surface 51 of the handle seat moves in conjunction with the inner edge surface 22 of the baffle 2. However, there may be a gap between 51 and 22, allowing external dust and sand to enter the circuit breaker. A seal is achieved by placing a sliding plate 4 between the cover 1 and the baffle 2.

[0038] As attached Figure 8 , 9 As shown, the faceplate 1 is rotatably mounted on the middle cover 9, and the faceplate 1 can rotate around the connecting shaft 91 between the middle cover 9 and the faceplate 1. After the faceplate 1 is installed in place, a decorative plate 6 is vertically and downwardly clipped onto the faceplate 1, and a decorative plate 7 is vertically and downwardly clipped onto the trip cover 8, ensuring clear product markings and a smooth, aesthetically pleasing surface. The decorative plates are made of plastic, and the product markings are printed on the decorative plates, ensuring clear product markings. This also changes the traditional method of attaching labels to the panels and covers, making assembly simpler. During the operation of the opening and closing of the brake lever 5, the slide plate 4 is installed in the space 3 and can slide under the action of the lever 5, sealing the gap between the lever 5 and the faceplate 1. The slide plate is installed between the faceplate and the baffle, and is assembled and disassembled on the middle cover as a component together with the faceplate, improving the convenience of installation and reducing the risk of losing the slide plate.

[0039] This utility model provides a sealing structure for a molded case circuit breaker, which includes a face cover 1, a baffle 2 fitted onto the inner side of the face cover 1, and a space 3 between the face cover 1 and the baffle 2. A sliding plate 4 is installed within the space 3 and can slide. The entire sealing structure adopts a sliding component form, which not only reduces the space occupied but also prevents parts from being scattered and lost.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
