Description

Circuit breaker housing

Technical field

This invention relates to the field of low voltage electrical appliances and, more particularly, to circuit breakers in low voltage electrical appliances.

Background technique

With the development of circuit breakers towards miniaturization, compactness, and modularization, in the development of many new products, the simple upper and lower height direction opening mode or the side width direction opening mode has not been able to satisfy the product. Assembly and commissioning requirements. In a highly compact circuit breaker, the circuit breaker is divided into a plurality of parts in the width direction, but often only a certain part of one part of the circuit breaker needs to be tested, repaired or replaced in the debugging and the like, thereby saving labor cost and time. Cost considerations have placed new structural requirements on circuit breakers.

For example, in the process of debugging the residual current protection action circuit breaker, the circuit breaker is first riveted, and then the operation characteristics of the circuit breaker are debugged. After the completion, the residual current protection characteristic is debugged, and the residual current protection characteristic must be in sequence. Debugging after the action characteristics, otherwise it will hinder the debugging of the action characteristics due to leakage current, but there is a certain chance that the relevant residual components need to be disassembled, repaired or replaced during the final residual current protection. In the past, when this situation was encountered, all the rivets of the entire circuit breaker had to be disassembled before the relevant components could be taken out for testing, repairing or replacement. After the completion, the riveting was repeated, but all the previous characteristics must be debugged again. The repeated work wastes a lot of manpower. Cost and time costs.

Summary of the invention

The present invention is directed to an outer casing of a circuit breaker that can replace components in a circuit breaker without removing the rivet.

According to an embodiment of the invention, a casing of a circuit breaker is provided, the casing has an opening, the opening is covered by a cover plate, and the cover plate is mounted on the outer casing, and the cover plate does not extend beyond the original outer contour of the outer casing, and is modularized The components are mounted into the housing through the openings.

In one embodiment, the aperture is a slot and the aperture is located on a bottom surface of the housing.

In one embodiment, the cover is located on the side of the rail of the bottom surface of the housing.

In one embodiment, the contour of the cover conforms to the bottom surface of the outer casing, the first end of the cover forms a projection, and the second end of the cover forms a snap.

In one embodiment, the buckle has elasticity.

In one embodiment, the outer casing has a snap face at a first end of the opening and a stepped surface at a second end of the opening. The protrusion of the first end of the cover plate cooperates with the step surface to form a fulcrum, and the cover plate rotates with the fulcrum as an axis to cover the opening. The buckle of the second end of the cover is engaged with the engaging surface, and the cover is fixed to the outer casing.

The outer casing of the circuit breaker of the present invention can easily replace the modular components through the cover plate and the opening, thereby avoiding the disassembly of the rivet and the re-commissioning of the characteristics, which can save a lot of labor cost and time cost.

detailed description

Referring to FIGS. 1 to 3, FIGS. 1 to 3 disclose an outer circuit breaker according to an embodiment of the present invention. shell. 1 shows the structure of the outer casing of the circuit breaker, FIG. 2 discloses a cross-sectional view of the outer casing of the circuit breaker, and FIG. 3 discloses the bottom surface of the outer casing of the circuit breaker.

As shown, the outer casing 101 of the circuit breaker has an opening 105. The opening 105 is covered by a cover 102. The cover 102 is mounted on the outer casing 101. The cover 102 does not extend beyond the original outer contour of the outer casing 101. The component 104 is mounted into the outer casing 101 through the opening 105.

In the illustrated embodiment, the aperture 105 is a slot and the aperture 105 is located on the bottom surface 106 of the housing 101. Therefore, the original shape and function of the four side faces and the top face of the outer casing 101 are completely unaffected. The main function of the bottom surface of the outer casing 101 is to engage with the rail, and the area occupied by the rail is small, so that a large area on the bottom surface 106 of the outer casing 101 does not originally perform any function, and the part is used as an opening. The aperture 105 has no effect on the original function of the housing 101. With continued reference to the drawings, the cover plate 102 is located on the side of the rail of the bottom surface 106 of the outer casing.

The outline of the cover plate 102 conforms to the bottom surface of the outer casing. Referring to the cross-sectional view shown in FIG. 2, the outline of the cover plate 102 coincides with the contour of the bottom surface of the outer casing 101, so that after the cover plate 102 is mounted to the outer casing 101, the cover plate 102 The original outer contour of the outer casing 101 does not change beyond the original outer contour of the outer casing 101, and thus does not affect the assembly of the outer casing 101 and the rail.

The first end of the cover plate 102 forms a bump 121, and the second end of the cover plate 102 forms a buckle 112. The buckle 112 has elasticity.

The outer casing 101 has a latching surface 111 at a first end of the opening 105 and a stepped surface 113 at a second end of the opening 105. The protrusion 121 of the first end of the cover plate 102 cooperates with the step surface 113 to form a fulcrum, and the cover plate 102 rotates with the fulcrum as an axis, covering the opening 105. The buckle 112 of the second end of the cover plate 102 is engaged with the engaging surface 111, and the cover plate 102 is fixed to the outer casing 101.

Fig. 4 is a view showing the mounting of the cover of the circuit breaker of the embodiment shown in Fig. 1 to the cover. When the cover 102 is required to close the opening 105, the protrusion 121 of the first end of the cover 102 is inserted into the stepped surface 113 to form a rotation fulcrum, and then the cover 102 is rotated around the fulcrum, and the first end of the cover 102 is The buckle 112 is in contact with the engaging surface 111, and the elastic buckle 112 is pressed to generate a certain degree of elastic deformation, and then is inserted into the engaging surface 111, after which the buckle 112 is restored and snapped on the engaging surface 111. The cover plate 102 is mounted to the outer casing 101. As shown in Figure 4, The mounting of the cover plate 102 does not require the use of other tools.

Figure 5 is a schematic view showing the removal of the cover by the outer casing of the circuit breaker of the embodiment shown in Figure 1. As shown, when the cover 102 needs to be removed, the buckle 112 is moved using the tool 103, and the buckle 112 is again compressed to elastically deform and slide out of the engaging surface 111. The cover plate 102 is again rotated by the fulcrum formed by the bump 121 and the stepped surface 113, and finally the bump 121 is withdrawn from the stepped surface 113 to complete the disassembly. At this time, the opening 105 is opened, and the modular component 104 can be taken out or placed through the opening 105.

The outer casing of the circuit breaker of the present invention can easily test, repair or replace the modular components through the cover plate and the opening, thereby avoiding the disassembly of the rivet and the re-commissioning of the characteristics, thereby saving a large labor cost and time cost. .

The above embodiments are provided to those skilled in the art to implement or use the present invention, and those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept. The scope of the invention is not limited by the embodiments described above, but should be the maximum range of the inventive features as claimed.
