Description

Technical Field

[0001] This utility model relates to the field of molded case circuit breaker technology, specifically a molded case circuit breaker based on the Internet of Things. Background Technology

[0002] IoT-based molded case circuit breakers (MCCBs) are intelligent electrical devices that deeply integrate traditional MCCBs with IoT, sensor, and communication technologies. They not only retain the basic protection functions of conventional MCCBs such as overload, short circuit, and undervoltage, but also enable intelligent capabilities such as real-time circuit status monitoring, remote data transmission, intelligent analysis and early warning, and remote control. They are the core terminal equipment for the intelligent and digital transformation of low-voltage power distribution systems.

[0003] A molded case circuit breaker based on the Internet of Things (IoT) disclosed in CN217468317U includes a line end protection component. The line end protection component has an L-shaped structure and a through hole. The line end protection component is inserted into a socket.

[0004] This IoT-based molded case circuit breaker lacks a specific installation structure and requires traditional bolt fixing or external brackets. Installation necessitates precise alignment of bolt holes and the use of tools such as wrenches, making single-person operation time-consuming. Similarly, disassembly requires removing each bolt individually, resulting in low maintenance efficiency. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a molded case circuit breaker based on the Internet of Things to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a molded case circuit breaker based on the Internet of Things, including a molded case circuit breaker body, a protective cover slidably connected to the front of the molded case circuit breaker body, a limit mechanism provided on the outer side of the molded case circuit breaker body, and an installation mechanism provided on the back end of the molded case circuit breaker body.

[0007] The installation mechanism includes a fixing plate, which is fixedly connected to the top and bottom of the back end of the molded case circuit breaker body. A sliding rod is slidably connected to the inner side of the fixing plate, a limiting plate is fixedly connected to the outer side of the sliding rod, an insert plate is fixedly connected to the inner side of the sliding rod, a distribution box mounting bracket is inserted into the outer side of the insert plate, a first spring is sleeved around the outer side of the sliding rod, and a pull plate is fixedly connected to the outer side of the limiting plate.

[0008] Preferably, there are two slide rods, which are fixedly connected to the left and right sides of the inner side of the limiting plate, respectively. The slide rods can limit the position of the insert plate, making the insert plate more stable during movement.

[0009] Preferably, the outer side of the first spring is fixedly connected to the inner side of the fixing plate, and the inner side of the first spring is fixedly connected to the outer side of the plug plate. When the plug plate is squeezed by the distribution box mounting bracket, the plug plate can push the sliding rod and the limiting plate to move outward. When the distribution box mounting bracket does not squeeze the plug plate, the elastic force of the first spring can push the plug plate back to its original position, so that the plug plate can be inserted into the distribution box mounting bracket, and the molded case circuit breaker body can be quickly installed on the front of the distribution box mounting bracket.

[0010] Preferably, the distribution box mounting frame has an inclined groove inside that corresponds to the position of the plug plate, and the outer side of the plug plate fits into the inner side of the inclined groove. The inclined groove allows the plug plate to be inserted into the distribution box mounting frame, making it convenient for workers to quickly install the molded case circuit breaker body.

[0011] Preferably, the limiting mechanism includes a fixed rod, which is fixedly connected to the top and bottom of the molded case circuit breaker body. A fixed plate is fixedly connected to the outside of the fixed rod. A pull plate is slidably connected to the periphery of the fixed rod. A connecting strip is fixedly connected to the outside of the pull plate. A rotating plate is fixedly connected to the outside of the connecting strip. A second spring is sleeved around the periphery of the fixed rod. An insert rod is fixedly connected to the inside of the pull plate.

[0012] Preferably, the outer side of the second spring is fixedly connected to the inner side of the fixed plate, and the inner side of the second spring is fixedly connected to the outer side of the pull plate. When the operator releases the force applied to the rotating plate, the elastic force of the second spring enables the second spring to push the pull plate and the plug rod downward, allowing the plug rod to penetrate the protective cover and insert into the body of the molded case circuit breaker, thereby limiting the position of the protective cover.

[0013] Preferably, the inner side of the protective cover has a circular hole corresponding to the position of the insertion rod, and the insertion rod is inserted into the inner side of the circular hole. The inner side of the protective cover has a sliding groove corresponding to the position of the fixed rod, and the fixed rod is slidably connected to the inside of the sliding groove. Through the circular hole, the insertion rod can pass through the inside of the protective cover. Through the sliding groove, when the protective cover slides to the front of the molded case circuit breaker body, the fixed rod is not likely to obstruct the movement of the protective cover.

[0014] Compared with the prior art, this utility model provides a molded case circuit breaker based on the Internet of Things, which has the following beneficial effects:

[0015] 1. In the installation mechanism of this IoT-based molded case circuit breaker, the first spring and the plug plate work together elastically, and the plug plate is automatically engaged by the inclined groove of the distribution box mounting bracket. The molded case circuit breaker body can be fixed without tools, and it can be unlocked and disassembled by pulling the pull plate, which greatly shortens the installation and maintenance time.

[0016] 2. In this IoT-based molded case circuit breaker, the limiting mechanism uses a second spring to drive the plug rod through the protective cover, achieving stable limiting of the protective cover. The protective cover can protect the switch of the molded case circuit breaker body, making it less likely for operators to accidentally touch the switch of the molded case circuit breaker body.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-4 This utility model provides a technical solution: a molded case circuit breaker based on the Internet of Things, including a molded case circuit breaker body 3, a protective cover 1 slidably connected to the front of the molded case circuit breaker body 3, a limit mechanism 2 provided on the outside of the molded case circuit breaker body 3, and an installation mechanism 4 provided on the back of the molded case circuit breaker body 3.

[0028] The mounting mechanism 4 includes a fixing plate 43, which is fixedly connected to the top and bottom of the back end of the molded case circuit breaker body 3. A sliding rod 45 is slidably connected to the inner side of the fixing plate 43. A limit plate 44 is fixedly connected to the outer side of the sliding rod 45. An insert plate 42 is fixedly connected to the inner side of the sliding rod 45. A distribution box mounting bracket 41 is inserted into the outer side of the insert plate 42. A first spring 46 is sleeved around the outer side of the sliding rod 45. A pull plate 47 is fixedly connected to the outer side of the limit plate 44.

[0029] Furthermore, there are two slide rods 45, which are fixedly connected to the left and right sides of the inner side of the limiting plate 44 respectively. The slide rods 45 can limit the insertion plate 42, making the insertion plate 42 more stable during movement.

[0030] Furthermore, the outer side of the first spring 46 is fixedly connected to the inner side of the fixing plate 43, and the inner side of the first spring 46 is fixedly connected to the outer side of the plug plate 42. When the plug plate 42 is squeezed by the distribution box mounting bracket 41, the plug plate 42 can push the slide rod 45 and the limiting plate 44 to move outward. When the distribution box mounting bracket 41 does not squeeze the plug plate 42, the elastic force of the first spring 46 can push the plug plate 42 back to its original position, so that the plug plate 42 can be inserted into the distribution box mounting bracket 41, and the molded case circuit breaker body 3 can be quickly installed on the front of the distribution box mounting bracket 41.

[0031] Furthermore, the distribution box mounting bracket 41 has an inclined groove inside that corresponds to the position of the plug plate 42, and the outer side of the plug plate 42 fits into the inner side of the inclined groove. Through the inclined groove, the plug plate 42 can be inserted into the distribution box mounting bracket 41, which facilitates the staff to quickly install the molded case circuit breaker body 3.

[0032] Example 2

[0033] Please see Figure 1-4 Furthermore, based on Embodiment 1, the limiting mechanism 2 further includes a fixed rod 21, which is fixedly connected to the top and bottom of the molded case circuit breaker body 3. A fixed plate 24 is fixedly connected to the outside of the fixed rod 21. A pull plate 22 is slidably connected to the periphery of the fixed rod 21. A connecting strip 26 is fixedly connected to the outside of the pull plate 22. A rotating plate 25 is fixedly connected to the outside of the connecting strip 26. A second spring 23 is sleeved around the periphery of the fixed rod 21. An insert rod 27 is fixedly connected to the inside of the pull plate 22.

[0034] Furthermore, the outer side of the second spring 23 is fixedly connected to the inner side of the fixed plate 24, and the inner side of the second spring 23 is fixedly connected to the outer side of the pull plate 22. When the operator releases the force on the rotating plate 25, the elastic force of the second spring 23 enables the second spring 23 to push the pull plate 22 and the insertion rod 27 downward, so that the insertion rod 27 can penetrate the protective cover 1 and be inserted into the body 3 of the molded case circuit breaker, thereby limiting the position of the protective cover 1.

[0035] Furthermore, a circular hole corresponding to the position of the insertion rod 27 is opened on the inner side of the protective cover 1, and the insertion rod 27 is inserted into the inner side of the circular hole. A sliding groove corresponding to the position of the fixing rod 21 is opened on the inner side of the protective cover 1, and the fixing rod 21 is slidably connected to the inside of the sliding groove. Through the circular hole, the insertion rod 27 can pass through the inside of the protective cover 1. Through the sliding groove, when the protective cover 1 slides to the front of the molded case circuit breaker body 3, the fixing rod 21 is not likely to block the movement of the protective cover 1.

[0036] In actual operation, when this device is used, when it is necessary to install the molded case circuit breaker body 3 into the inside of the distribution box mounting bracket 41, place the molded case circuit breaker body 3 on the front of the distribution box mounting bracket 41, push the insert plate 42 at the back end of the molded case circuit breaker body 3 to the front of the distribution box mounting bracket 41, so that the insert plate 42 can be squeezed by the distribution box mounting bracket 41, so that the insert plate 42 can drive the limiting plate 44 to move through the slide rod 45, so that the insert plate 42 can squeeze the first spring 46. When the distribution box mounting bracket 41 does not squeeze the insert plate 42, the elastic force of the first spring 46 can push the insert plate 42 into the inside of the distribution box mounting bracket 41, so that the molded case circuit breaker body 3 can be quickly installed on the front of the distribution box mounting bracket 41.

[0037] When it is necessary to install the protective cover 1 onto the front of the molded case circuit breaker body 3, slide the protective cover 1 onto the front of the molded case circuit breaker body 3, so that the protective cover 1 slides around the fixed rod 21. After the protective cover 1 slides to the appropriate position, the operator pulls the rotating plate 25 upward, so that the rotating plate 25 can drive the pulling plate 22 and the plug rod 27 to move upward through the connecting bar 26. Rotate the rotating plate 25, so that the rotating plate 25 drives the pulling plate 22 and the plug rod 27 to rotate through the connecting bar 26, so that the plug rod 27 rotates from a vertical position. When the circuit is in a horizontal position, the operator releases the force applied to the rotating plate 25. Through the elastic force of the second spring 23, the second spring 23 pushes the pulling plate 22 and the insertion rod 27 downward, allowing the insertion rod 27 to penetrate the protective cover 1 and insert into the molded case circuit breaker body 3. This limits the position of the protective cover 1, ensuring that the protective cover 1 protects the switch on the front of the molded case circuit breaker body 3, making it less likely for the operator to accidentally touch the switch of the molded case circuit breaker body 3. The model of the molded case circuit breaker body 3 is NXM-63S.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
