Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to a circuit breaker assembly and a related attachment component. Background Art

[0002] Circuit breakers are widely used in the electrical field. Generally, the circuit breaker is mounted on a flat mounting surface of a device or a wall. In some cases, the mounting surface on the device or the wall is provided with a bracket track. Accordingly, the circuit breaker is mounted to the bracket track by a movable circuit breaker locking clip provided on the circuit breaker housing, thereby being mounted to the device or the wall.

[0003] In some applications, other related components or devices are attached to the existing circuit breaker. For example, a transformer is attached to the circuit breaker to detect the current flowing through the circuit breaker, so as to further control the operation of the circuit breaker. In this case, it is hoped that the assembled circuit breaker and related components can still be conveniently installed on the original bracket track on the equipment or wall.

[0004] However, components such as instrument transformers may need to be attached near the existing circuit breaker locking clips of the circuit breaker, which hinders the installer from accessing and operating the circuit breaker locking clips in a traditional manner. As a result, it becomes difficult to install the assembled circuit breaker and related components or to install the circuit breaker and related components one after another. Therefore, it is desirable to have a solution that is easy to assemble the circuit breaker and related components to each other, and to subsequently install the assembled circuit breaker and related components to equipment or walls without changing the existing circuit breaker and bracket rails.

[0084] The present invention will be described in detail below by describing exemplary embodiments.

[0085] Figure 1 and Figure 2 The perspective views of the circuit breaker assembly 1 according to the present invention are shown from different angles. Figure 1 and Figure 2 As shown, the circuit breaker assembly 1 includes a circuit breaker 10 and an attachment component 20 attached to the circuit breaker 10. The attachment component 20 is, for example, a transformer. The circuit breaker 10 includes a circuit breaker body 100 and a circuit breaker locking clip 150, and the attachment component 20 includes an attachment body 200 and an attachment locking clip 250. The circuit breaker body 100 has a circuit breaker attachment surface 101 on one side thereof, and the circuit breaker attachment surface 101 and the attachment component attachment surface 201 of the attachment body 200 are connected to each other, so that the circuit breaker 10 and the attachment component 20 are assembled together.

[0086] Specifically, if Figure 1 and Figure 2 As shown, the attachment component 20 may further include an attachment body extension 220, which extends from the attachment body 200, for example, forms an L-shaped structure together with the attachment body 200, and is connected to the circuit breaker body 100 at a side different from the attachment component attachment surface 201. The L-shaped structure formed by the attachment body 200 and the attachment body extension 220 is used, for example, to be assembled to a zero-sequence transformer of the circuit breaker 10.

[0087] Continue to refer to Figure 1 and Figure 2 The circuit breaker body 100 also has a circuit breaker distal end face 102 that is substantially opposite to the circuit breaker attachment face 101 and a circuit breaker mounting face 103 connected between the circuit breaker attachment face 101 and the circuit breaker distal end face 102. When the circuit breaker 10 or the circuit breaker assembly 1 is mounted on a device or a wall, the circuit breaker mounting face 103 is configured to face the device or the wall. The circuit breaker locking clip 150 is configured to be movably mounted on the circuit breaker mounting face 103 for mounting the circuit breaker 10 or the circuit breaker assembly 1, as described in detail later.

[0088] The attachment body 200 has an attachment component distal end face 202 that is substantially opposite to the attachment component attachment face 201 and an attachment component mounting face 203 connected between the attachment component attachment face 201 and the attachment component distal end face 202. When the attachment component 20 is attached to the circuit breaker 10, the attachment component mounting face 203 is adjacent to the circuit breaker mounting face 103 and can be substantially coplanar. Furthermore, when the circuit breaker 10 and the attachment component 20 assembled with each other are installed together on a device or a wall, the attachment component mounting face 203 is configured to face the device or the wall. The attachment locking clip 250 is configured to be movably mounted on the attachment component mounting face 203, so that the attachment locking clip 250 can be attached to the circuit breaker locking clip 150, and then the movement of the attachment locking clip 250 can drive the movement of the circuit breaker locking clip 150, as described in detail later.

[0089] Next, refer to Figure 1-2 and Figure 7-10 First, the manner in which the circuit breaker locking clip 150 mounts the circuit breaker 10 to a device or a wall and the related structure of the circuit breaker locking clip 150 are described.

[0090] The circuit breaker body 100 is provided with a support rail receiving groove 105 adjacent to the circuit breaker mounting surface 103, and the support rail receiving groove 105 is used to receive a support rail (not shown) arranged on the surface of the equipment or wall. For example, the support rail is received in the support rail receiving groove 105 in a substantially shape-fitting manner. The two sides of the support rail receiving groove 105 along its longitudinal direction (the third direction D3 in the drawings) are respectively the circuit breaker distal end face 102 and the support rail supporting surface 104 arranged oppositely, and the circuit breaker distal end face 102 and the support rail supporting surface 104 will be respectively docked with the two sides of the support rail along the longitudinal direction.

[0091] Reference Figures 7 to 10 The circuit breaker locking clip 150 has a locking portion 151 at one end and a driven portion 152 at the other end opposite to the end, wherein the locking portion 151 is closer to the bracket rail receiving groove 105. The circuit breaker locking clip 150 extends from the locking portion 151 to the driven portion 152 substantially along the first direction D1, and the circuit breaker locking clip 150 can be in the first direction D1 in the locking position P1 ( Figures 7 to 9 ) and release position P2( Fig.10 ) between. For example, the circuit breaker locking clip 150 is mounted on the circuit breaker mounting surface 103 in the form of a slider for sliding. Figures 7 to 10 As shown in detail, the circuit breaker locking clip 150 is embedded in a recessed track on the circuit breaker mounting surface 103 so that the surface of the circuit breaker locking clip 150 facing away from the bottom surface of the recessed track is flush with the remaining surface of the circuit breaker mounting surface 103 .

[0092] according to Figures 7 to 10When the circuit breaker locking clip 150 is in the locking position P1, the locking portion 151 of the circuit breaker locking clip 150 protrudes the farthest from the circuit breaker distal end surface 102 in the first direction D1, thereby the locking portion 151 can be locked to the bracket rail on the device or wall, so that the circuit breaker 10 can be installed on the device or wall. On the other hand, when the circuit breaker locking clip 150 is in the release position, the locking portion 151 retracts away from the bracket rail relative to the circuit breaker distal end surface 102, thereby leaving the bracket rail, and thus releasing the circuit breaker 10 from the bracket rail.

[0093] It should be noted that in some traditional settings, when the circuit breaker is installed separately to the equipment or wall, the installation surface of the circuit breaker is arranged toward and close to the surface of the equipment or wall. At this time, the installer can move the circuit breaker locking clamp by accessing the driven part of the circuit breaker locking clamp on one side of the circuit breaker attachment surface (for example, by inserting a tool such as a screwdriver into the through hole of the driven part). According to the utility model, when it is necessary to attach the attachment component 20 to the circuit breaker 10, the attachment component 20 and the circuit breaker 10 are first assembled to each other, and then the assembled circuit breaker 10 and the attachment component 20 (that is, the assembled circuit breaker assembly 1) are installed to the equipment or wall. According to the utility model, during the installation process, the circuit breaker locking clamp 150 is driven to move by driving the attachment locking clamp 250 to move, thereby installing the circuit breaker assembly 1.

[0094] Next, refer to Figure 3A and Figure 3B The configuration of the attachment locking clip 250 will be described in detail.

[0095] like Figure 3A and Figure 3B As shown, the attachment locking clip 250 has a driving portion 251 and an operating portion 252 located at opposite ends, respectively, and a main body 255 located between the driving portion 251 and the operating portion 252 .

[0096] The main body 255 has a substantially rectangular flat shape. The main body 255 is provided with protruding cylindrical portions 261, 262 on two narrower opposite sides between the driving portion 251 and the operating portion 252. The two cylindrical portions 261, 262 have a common axis L, and the axis L is perpendicular to the direction defined by the driving portion 251 and the operating portion 252 (in the assembled circuit breaker assembly 1, the axis L is also perpendicular to the first direction D1). A wider lateral surface 253 of the main body 255 is a plane, and the oppositely facing wider lateral surfaces 254 of the main body 255 are arranged as two planar portions extending at a certain angle to each other. Among them, the planar portion of the surface 254 close to the driving portion 251 is parallel to the surface 253, and the planar portion of the surface 254 close to the operating portion 252 starts from the position of the cylindrical portions 261, 262 and gradually approaches the surface 253 in the direction toward the operating portion 252. The main body 255 may also be provided with other internal hollow structures (such as through holes, etc.) to assist in manufacturing or enhance strength.

[0097] The driving portion 251 is configured to drive the driven portion 152 of the circuit breaker locking clip 150. Specifically, the driving portion 251 extends from the main body 255 and is provided with a protrusion 257 at the end away from the main body 255. Both sides of the base of the protrusion 257 are also provided with protruding, relatively small buckle portions 258.

[0098] The operation unit 252 is configured to be operated by an installer or the like. Figure 3A and 3B As shown, the operating portion 252 has a through hole 256 to facilitate a tool such as a screwdriver to be inserted into the through hole 256 and to apply a force to the operating portion 252 via the through hole 256 .

[0099] Figures 4 to 6 The process of installing the attachment locking clip 250 onto the attachment body 200 is shown.

[0100] like Figure 4 As shown, the attachment body 200 includes an attachment body outer shell 232, which is connected to the attachment body inner shell 231 ( Figure 6) together surround the internal volume of the attachment body 200. The attachment body outer shell 232 is provided with a recessed track 210 at the position of the attachment component mounting surface 203, and the recessed track 210 extends longitudinally along the first direction D1 and is recessed toward the attachment body 200 for receiving the attachment locking clip 250. The recessed track 210 is provided with grooves 211 and 212 extending along the first direction on both sides along the first direction D1. The bottom surface 213 of the recessed track 210 is defined between the grooves 211 and 212, and the bottom surface 213 is a plane. The ends of the grooves 211 and 212 located at the distal end surface 202 of the attachment component are provided with baffles 216 and 217 respectively. An opening 215 is formed between the baffles 216 and 217, so that the operating portion 252 of the attachment locking clip 250 can always protrude from the distal end surface 202 of the attachment component through the opening 215.

[0101] like Figure 5 As shown, the attachment locking clip 250 can be loaded into the recessed track 210 from the side opposite to the distal end surface 202 of the attachment component, generally along the first direction D1, so that the driving portion 251 of the attachment locking clip 250 faces away from the distal end surface 202 of the attachment component, and the surface 254 of the attachment locking clip 250 is opposite to the bottom surface 213 of the recessed track 210. As a result, the grooves 211 and 212 respectively receive the cylindrical portions 261 and 262 of the attachment locking clip 250, so that the attachment locking clip 250 can translate relative to the recessed track 210 (i.e., relative to the attachment body 200) along the first direction D1 and rotate around the axis L of the cylindrical portions 261 and 262. At the same time, the attachment component internal device 230 (such as a coil, etc.) can be installed in the other internal space defined by the outer shell 232 of the attachment body.

[0102] like Figure 6 As shown, after the attachment locking clip 250 is loaded into the recessed track 210, the attachment body inner shell 231 is installed on the attachment body outer shell 232. The attachment body inner shell 231 is located at the attachment component attachment surface 201 of the attachment body 200, and it and the corresponding part of the attachment body outer shell 232 together surround the installed attachment component internal device 230. On the other hand, the two stopper portions ( Figure 6 A stopper 235 is shown (shown) disposed at one end of the grooves 211, 212 opposite to the baffles 216, 217, respectively, so as to limit the movement of the cylindrical portions 261, 262 along the first direction D1 together with the baffles 216, 217. Thus, the attachment locking clip 250 can move between the third position P3 and the fourth position P4 along the first direction D1. In the third position P3, the operating portion 252 of the attachment locking clip 250 protrudes the least from the distal end surface 202 of the attachment component (i.e., at Figure 6In the third position P4, the operating portion 252 of the attachment locking clip 250 protrudes the far end surface 202 of the attachment component the most (i.e., in the attachment locking clip 250 is against the stopper to the left). Figure 6 It should be noted that when the attachment locking clip 250 moves between the third position P3 and the fourth position P4, the operating portion 252 always protrudes from the distal end surface 202 of the attachment component to facilitate the operation of the installer.

[0103] Next, refer to Figure 7-10 , describing the steps of assembling the circuit breaker 10 and the attachment component 20 to form the circuit breaker assembly 1 , and then installing the circuit breaker assembly 1 .

[0104] First, on the circuit breaker 10, the circuit breaker locking clip 150 is moved to the locking position P1. On the other hand, on the attachment member 20, the attachment locking clip 250 is moved to the third position P3, and the attachment locking clip 250 is rotated with its cylindrical portion as the axis, so that the driving portion 251 is deflected away from the bottom surface 213 of the recessed track. Since the bottom surface 213 of the recessed track is a plane extending along the first direction D1, the surface 254 of the attachment locking clip 250 opposite to the bottom surface 213 is composed of the aforementioned two angled plane portions (see also Fig. 9 ), the attachment locking clip 250 is able to perform such rotation.

[0105] Then, in the aforementioned state, the circuit breaker body 100 and the attachment body 200 are connected to each other, wherein the circuit breaker attachment surface 101 and the attachment component attachment surface 201 are connected to each other. In this process, the attachment locking clip 250 is in the third position P3, and the protrusion 257 of its driving portion 251 can pass over the edge of the driven portion 152 of the circuit breaker locking clip 150 and move to the side of the through hole 156 of the driven portion 152 away from the circuit breaker body 100. Thereafter, the installer can rotate the attachment locking clip 250 by hand or with a tool so that the protrusion 257 of the driving portion 251 enters the through hole 156 of the driven portion 152, thereby attaching the attachment locking clip 250 to the circuit breaker locking clip 150. This process is still achieved by rotating the attachment locking clip 250 with its cylindrical portion as the axis.

[0106] Figure 8 FIG. 2 shows a state where the protrusion 257 of the driving portion 251 of the attachment locking clip 250 has entered the through hole 156 of the driven portion 152. Figure 8 At the rotation angle shown (attachment rotation angle), the surface 253 of the attachment locking clip 250 facing away from the attachment body 200 is flush with the remaining plane of the attachment component mounting surface 203. Thus, the circuit breaker 10 and the attachment component 20 assembled with each other can be arranged on a flat surface of a device or a wall with their respective mounting surfaces fittingly. Fig. 9 A partial cross-sectional view of the circuit breaker assembly 1 showing this situation more clearly shows the position and matching relationship between the driving portion 251 of the attachment locking clip 250 and the driven portion 152 of the circuit breaker locking clip 150 .

[0107] exist Figure 8 and Fig. 9 In the state, the attachment locking clip 250 can be moved along the first direction D1 by applying a force to the operating portion 252 of the attachment locking clip 250 at the distal end surface 202 of the attachment component, and the attachment locking clip 250 then moves the circuit breaker locking clip 150 in the first direction D1 through the driving portion 251. For example, when the attachment locking clip 250 is moved from the third position P3 to the fourth position P4 ( Fig.10 ), the circuit breaker locking clip 150 moves from the locking position P1 to the releasing position P2 accordingly ( Fig.10 ). At this time, the bracket rail on the surface of the equipment or wall can enter the bracket rail receiving groove 105 on the circuit breaker body 100, and the circuit breaker mounting surface 103 and the attachment component mounting surface 203 can fit the surface of the equipment or wall. Thereafter, the installer moves the attachment locking clip 250 from the fourth position P4 back to the third position P3 ( Figure 8 , Fig. 9 ), the circuit breaker locking clip 150 moves back to the locking position P1 accordingly ( Figure 8 , Fig. 9 ), thereby locking to the bracket rail, whereby the entire circuit breaker assembly 1 is installed to the equipment or wall.

[0108] in addition, Fig. 9 Surfaces 253 and 254 to which locking clip 250 is attached are also shown from the side. Fig. 9 As shown in FIG. 1 , the bottom surface 213 of the recessed track 210 is a plane extending along the first direction D1, and the gap between the surface 254 of the attachment locking clip 250 facing the bottom surface 213 and the bottom surface 213 gradually increases along the first direction D1 from the position of the cylinders 261 and 262 toward the operating portion 252. Therefore, Fig. 9 It is more clearly shown how the flat structured attachment locking clip 250 can be rotated within the relatively limited space of the recessed track 210 to attach or detach the circuit breaker locking clip 150 .

[0109] In addition, the above installation process can also be performed in reverse, for example, to repair or replace components in the circuit breaker assembly 1. That is, the installer removes the circuit breaker assembly 1 from the bracket track on the equipment or wall by operating the operating portion 252 of the attachment locking clip 250, and then, for example, by pressing the portion of the attachment locking clip 250 close to the operating portion 252, the attachment locking clip 250 is rotated around the axis L, so that the driving portion 251 of the attachment locking clip 250 is disengaged from the driven portion 152 of the circuit breaker locking clip 150, and the circuit breaker 10 and the attachment component 20 can be separated.

[0110] Based on the above arrangement, the driving portion 251 of the attachment locking clip 250 may have a further optimized structure to better detachably attach to the driven portion 152 of the circuit breaker locking clip 150. For example, Figure 3A and 3B As shown, a part of the surface of the protrusion 257 on the driving part 251 can be configured to match a part of the inner surface of the through hole 156 to increase the contact area between the protrusion 257 and the through hole 156, so that the driving part 251 can stably apply force to the driven part 152. For another example, the buckle portion 258 on the driving part 251 can be set to a hemispherical shape with a smaller size, so that the buckle portion 258 can easily pass over the corresponding edge inside the through hole 156 through elastic deformation, thereby engaging or disengaging the protrusion 257 with the through hole 156. In addition, the operating portion 252 of the attachment locking clip 250 can have a further optimized structure. For example, the operating portion 252 is set so that when the attachment locking clip 250 is attached to the circuit breaker locking clip 251, the through hole 256 is substantially perpendicular to the attachment component mounting surface 203, so as to facilitate the tool to extend into the through hole 256 for operation.

However, it can be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the protection scope of the present invention.
