The application provides a circuit breaker.
In an embodiment of the present application, as shown in fig. 1 to 5, the circuit breaker includes a first functional module 100, a second functional module 400, a socket 200, and a plug 300. The first functional module 100 and the second functional module 400 are adjacent, and the first functional module 100 and the second functional module 400 may be one of a power module, a switch module, and a communication module. Different functions of the circuit breaker can be realized by the cooperation between the first functional module 100 and the second functional module 400. In the present embodiment, the first functional module 100 and the second functional module 400 of the circuit breaker are provided to have different functions. However, in some embodiments of the present application, the first functional module 100 and the second functional module 400 may also be configured to have the same function, which is not limited thereto.
Specifically, a socket 200 is mounted to the first functional module 100, the socket 200 having electrical connection contacts of the first functional module 100. The plug 300 is movably mounted to the socket 200 and can be extended or retracted with respect to the socket 200. The plug 300 is electrically connected to the socket 200, and the plug 300 is always electrically connected to the socket 200 when the plug 300 moves relative to the socket 200.
Specifically, the second functional module 400 is provided with a slot (not shown), and the plug 300 is inserted into the slot to electrically connect the first functional module 100 with the second functional module 400. Obviously, the electrical connection contacts of the second functional module 400 are provided in the socket. Thus, when the plug 300 moves relative to the socket 200 and is inserted into the socket, the electrical connection between the first functional module 100 and the second functional module 400 can be achieved through the plug 300. And when the plug 300 is disengaged from the slot of the second functional module 400, the electrical connection between the second functional module 400 and the first functional module 100 is broken.
It can be appreciated that in the prior art, since the power modules, the switch modules, the communication modules and the like of the circuit breaker are electrically connected by the pins or the wires, when a certain module fails and needs to be replaced or maintained, each module in the whole circuit breaker needs to be disassembled two by two, so that the failed module can be powered off and replaced or maintained. Meanwhile, when the repaired module is reloaded, a plurality of functional modules are required to be electrically connected in sequence. Obviously, the electrical connection mode between the modules of the conventional circuit breaker causes the disassembly and assembly of the modules of the circuit breaker to be very complicated. Especially when the circuit breaker has a large number of modules, the workload of maintenance personnel is greatly increased, and the working efficiency is seriously affected.
In order to solve the drawbacks of the conventional circuit breaker, the circuit breaker of the present application proposes that the plug 300 is movably mounted on the socket 200, and a slot is provided on the second functional module 400, and the connection or disconnection between the first functional module 100 and the second functional module 400 is achieved by the plug 300 entering or leaving the slot. In this way, when a certain functional module (the first functional module 100 or the second functional module 400) in the circuit breaker is replaced or repaired, the plug 300 is only required to be driven to be separated from the slot of the second functional module 400, so that the electrical connection between the first functional module 100 and the second functional module 400 can be disconnected. Then, only the functional module to be replaced or maintained can be removed. And after maintenance or replacement is completed, the functional module is installed back to the original position. It can be seen that the circuit breaker of the present application greatly simplifies the assembly and disassembly of the various modules of the circuit breaker by the movement of the plug 300 between the socket 200 and the socket, as compared to the prior art.
Further, in the present embodiment, a slot is further disposed on a side of the first functional module 100 facing away from the socket 200, and a socket 200 is further disposed on a side of the second functional module 400 facing away from the slot. It should be understood that, in this way, the first functional module 100 may be connected to two second functional modules 400 at the same time, and the second functional module 400 may be connected to two first functional modules 100 at the same time. Therefore, the circuit breaker can realize interconnection of a plurality of functional modules in the circuit breaker, realize free combination among different functional modules, and obtain the circuit breaker of different specifications, and the practicality is higher. And each functional module can be quickly disassembled and assembled, and each module of the circuit breaker is convenient to maintain and replace.
As shown in fig. 1 and 2, in the circuit breaker of the present embodiment, the circuit breaker includes a plurality of first functional modules 100 and a plurality of second functional modules 400, and the plurality of first functional modules 100 and the plurality of second functional modules 400 are sequentially spliced. And the adjacent first functional module 100 and second functional module 400 are electrically connected by the mutual matching of the plug 300, the socket 200 and the slot. Of course, in other embodiments, the circuit breaker may be composed of only the first functional module 100 and the second functional module 400.
Preferably, in order to facilitate the mating with the plug 300, a socket 200 is also disposed in the slot of the second functional module 400, and the socket 200 is electrically connected to the second functional module 400. Meanwhile, since the electrical connection contacts of the first functional module 100 and the second functional module 400 are formed using the same components, the manufacturing cost of the circuit breaker can be reduced to some extent. Because the socket 200 can be arranged in the slot, and the same functional module can be provided with the socket 200 and the slot at the same time, the socket 200 with two opposite openings can be arranged in the same functional module of the circuit breaker at the same time, so that the cost of the circuit breaker is reduced. Of course, in other embodiments, other structures, such as an electrical clip, may be disposed in the slot of the second functional module 400 to serve as an electrical connection contact with the second functional module 400.
Referring to fig. 3 to 4, in the present embodiment, the plug 300 is slidably disposed in the socket 200. The plug 300 is extended or contracted with respect to the socket 200 in a sliding manner, and has a simple structure, convenient implementation, and convenient operation by a user. It should be noted that, in other embodiments of the present application, the plug 300 may also be rotatably connected to the socket 200. The socket 200 is partially extended out of the socket 200 by rotation of the plug 300 relative to the socket 200. To facilitate the movement of the plug 300, the plug 300 may be configured in an arc shape, and correspondingly, the slot on the second functional module 400 is also configured in an arc shape.
Further, in the present embodiment, the socket is formed on a side wall of the second functional module 400 opposite to the first functional module 100, the socket 200 is disposed in the housing of the first functional module 100, and a through opening is opened on the side wall of the housing of the first functional module 100 facing the second functional module 400, and the through opening is disposed corresponding to the socket 200 and opposite to the socket. So designed, the plug 300 can be facilitated to enter or exit the second functional module 400. In addition, when the plug 300 is inserted into the slot of the second functional module 400, the part of the plug 300 responsible for electrical connection is not exposed, which is safer. Of course, in other embodiments, the socket 200 may be disposed outside the housing of the first functional module 100, and the housing of the second functional module 400 is also disposed with a corresponding plugging portion, and the slot is disposed on the plugging portion.
Referring to fig. 4 and 5, in the present embodiment, the plug 300 includes a handle 310 and a connection terminal 320. The handle 310 is slidably disposed on the housing of the first functional module 100, and the connection terminal 320 is disposed on the socket 200 and is fixedly connected to the handle 310. In use, the connection terminals 320 are extended or retracted relative to the socket 200 by sliding the handle 310 relative to the first functional module 100. The handle 310 can apply force to the user, and can prevent the connection terminal 320 from being exposed to generate electric leakage, thereby being safer.
Referring to fig. 5 and 6, the handle 310 includes a mounting base 311, and the mounting base 311 is provided with a plurality of connection terminals 320 in parallel along a direction perpendicular to the sliding direction of the plug 300. In this way, according to the functions of the first functional module 100 and the second functional module 400, different numbers of connection terminals 320 may be disposed on the mounting base 311, and different connection terminals 320 have different transmission functions, where the connection functions of the connection terminals 320 include, but are not limited to, current transmission, data transmission, and the like. By such design, different functional modules can be adapted, and the number of the connecting terminals 320 is correspondingly designed, so that the application range of the plug 300 is widened. Of course, in other embodiments of the present application, only one connection terminal 320 may be mounted on the mounting base 311.
Further, the handle 310 further includes a pulling piece 312, the pulling piece 312 is disposed on the mounting seat 311, and a force application portion 3121 is protruding from a middle portion of a side of the pulling piece 312 facing away from the mounting seat 311. In use, a user pushes the connection terminal 320 by pulling the paddle 312, causing the connection terminal 320 to slide relative to the receptacle 200. Therefore, the connection terminal 320 is opposite to the biasing portion 3121 protruding from the side of the mounting seat 311, so that the user can apply a force to push the paddle 312. The pulling piece 312 needs to be pushed back and forth, so that the pulling piece 312 is forced to be protruded from the middle part of the pulling piece 312, thereby being more convenient for users to use. It should be noted that, in other embodiments of the present application, a groove may be concavely formed on a side of the paddle 312 facing away from the mounting seat 311, and the groove is formed in a middle portion of the paddle 312. Thus, the user can push the pulling piece 312 conveniently.
Further, a side of the pulling piece 312 facing away from the mounting seat 311 is further provided with a protruding anti-slip rib 3122, and the anti-slip rib 3122 is separately provided at two sides of the force application portion 3121. By providing the anti-slip ribs 3122 on the dial 312, the friction coefficient of the dial 312 surface can be increased, thereby increasing the friction force that the user receives when pushing the dial 312. This design may facilitate the user pushing on the paddle 312.
As shown in fig. 6, in order to make the user more intuitively understand the on/off state between the first functional module 100 and the second functional module 400, a sign 3123 is further disposed on a side of the dial 312 facing away from the mounting seat 311, where the sign 3123 includes a locking sign in a table connection state and an unlocking sign in a table disconnection state, and the locking sign and the unlocking sign are respectively disposed on two sides of the force application portion 3121.
In this embodiment, the pulling piece 312 is detachably connected to the mounting seat 311. It can be appreciated that the pulling piece 312 is detachably connected with the mounting seat 311, so that the connection terminals 320 can be mounted on the socket 200, and the pulling piece 312 with different specifications can be selected according to the number of the connection terminals 320. Of course, in other embodiments of the present application, the pulling piece 312 and the mounting seat 311 may be fixedly connected or integrally formed.
Referring to fig. 6 to 8, two first hooks 313 are protruding from a side of the mounting base 311 facing the pulling piece 312, the two first hooks 313 are disposed opposite to each other, two second hooks 314 are protruding from a side of the pulling piece 312 facing the mounting base 311, and the two second hooks 314 are respectively engaged with the two first hooks 313. The first hook 313 and the second hook 314 are matched in a clamping manner, so that the detachable connection between the poking piece 312 and the mounting seat 311 is realized, the poking piece 312 and the mounting seat 311 are relatively simple in structure, and the poking piece 312 and the mounting seat 311 are quite convenient to assemble and disassemble. Of course, in other embodiments of the present application, the two first hooks 313 may be disposed opposite to each other. It should be noted that, in other embodiments of the present application, the dial 312 and the mounting seat 311 may be detachably connected by plugging, screwing, riveting, or the like.
Specifically, in the present embodiment, the two first hooks 313 are disposed opposite to each other along the extending direction of the mounting seat 311, and the pulling piece 312 is further provided with two stoppers 315 protruding from two sides of the second hook 314. The two stoppers 315 are used for abutting against two sides of the first hook 313 along the sliding direction of the pulling piece 312 when the first hook 313 is clamped with the second hook 314. Since the first hook 313 is disposed along the extending direction of the mounting seat 311, there is no limit between the dial 312 and the mounting seat 311 along the sliding direction of the dial 312 after the first hook 313 is clamped with the second hook 314. The paddle 312 slides along the direction, which may cause the paddle 312 and the mounting base 311 to separate from each other. In order to avoid the above situation, two stoppers 315 are added on two sides of the second hook 314 to abut against two sides of the first hook 313 along the sliding direction of the pulling piece 312. Thus, the separation of the pulling piece 312 and the mounting seat 311 can be prevented, and the stability of the connection between the pulling piece 312 and the mounting seat 311 can be improved. It should be noted that, in other embodiments of the present application, the two first hooks 313 may be disposed opposite or opposite to each other along the sliding direction of the pulling piece 312 on the mounting base 311, and the pulling piece 312 does not need to be correspondingly provided with the stop block 315.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the application, and all equivalent structural changes made by the description of the present application and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the application.
