Detailed Description
The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include, for example, "one or more" such forms of expression, unless the context clearly indicates to the contrary.
Reference in the specification to "one embodiment" or "a particular embodiment" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.
In order to facilitate understanding of the contact mechanism, the distribution box and the distribution system provided by the embodiment of the application, an application scenario thereof is first described below. The contact mechanism can be a circuit breaker, and the circuit breaker can be widely applied to various power distribution systems. For example, circuit breakers may be used in power distribution systems for domestic electricity to conduct, carry, break electrical current between a power supply network and a domestic circuit. Taking four home circuits as examples, the power distribution system is provided with a first home circuit, a second home circuit, a third home circuit and a fourth home circuit. In addition, a breaker is correspondingly arranged in each household circuit, and the breakers are a first breaker, a second breaker, a third breaker and a fourth breaker respectively. The circuit breaker can be switched to a closed state when a circuit between the power supply network or the power supply and the home circuit is required to be connected, and can be switched to an open state when the circuit between the power supply network and the home circuit is required to be disconnected. The on-off state of the household circuit is controlled by controlling the on-off state of the circuit breaker. For example, when the first household meets the normal electricity demand, the worker can switch the first circuit breaker to the closed state, so that the first household can normally use electricity. When the second family is delineating the electricity fee or is in an abnormal state, the staff can switch the second circuit breaker to be in an off state so that the user cannot use electricity.
In addition, the circuit breaker can be applied to a power distribution system of enterprise electric equipment or public electric equipment and used for switching on, carrying and breaking current between a power supply network and the enterprise electric equipment or public electric equipment. For example, when the electric equipment (such as the 4G base station, the 5G base station, etc.) needs to work normally, the working personnel can switch the circuit breaker to be in a closed state, so that the power supply network can provide the electric energy required by the normal work for the electric equipment. When the electric equipment needs to be overhauled and maintained, a worker can switch the circuit breaker into an off state so as to conveniently overhaul, maintain and the like the electric equipment.
In the circuit breaker, a contact system may be provided, and the contact system may include a fixed contact and a moving contact, and when the fixed contact and the moving contact are in contact, the circuit breaker is in a closed state, and when the moving contact is moved or rotated to be separated from the fixed contact, the circuit breaker is in an open state. The closed and open states of the circuit breaker can be switched by operating the contact and separation states between the fixed contact and the movable contact. Currently, a mechanical operation button for operating the position of a moving contact is provided in a circuit breaker, and a user must go to the circuit breaker site when the closed and open states of the circuit breaker need to be switched, so that there is a great inconvenience and low efficiency. At present, in order to realize remote operation of a circuit breaker, a motor can be arranged in the circuit breaker, the motor is in transmission connection with a moving contact through a transmission mechanism such as a gear and a speed reducer, and the moving contact can be driven to move through rotation of the motor, so that the moving contact is contacted with or separated from a fixed contact. The on-off state of the circuit breaker can be switched by remotely controlling the running state of the motor. However, in practical application, the cost of the motor is high, so that the manufacturing cost of the circuit breaker can be increased, and the circuit breaker is inconvenient to widely use. In addition, the motor is also required to be driven by matching with a gear, a speed reducer and other transmission parts, so that the cost and the volume of the circuit breaker are increased, and the miniaturization design of the circuit breaker is inconvenient. In addition, the reliability of the circuit breaker is reduced due to the addition of more moving parts (such as gears). Therefore, the application provides the contact mechanism which can be controlled remotely, has a simple structure and is safe and reliable.
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a contact mechanism according to an embodiment of the present application, and fig. 2 is a schematic exploded structural view of the contact mechanism according to an embodiment of the present application. As shown in fig. 1 and 2, the contact mechanism in the embodiment of the present application includes a housing 1, an operating member 2, a linkage member 3, a fixed contact 4, a moving contact 5, an electromagnetic structure 6, and a micro switch 7. Wherein, the linkage member 3, the fixed contact 4, the moving contact 5, the electromagnetic structure 6 and the micro switch 7 are all arranged on the shell 1. The micro switch 7, the fixed contact 4 and the moving contact 5 are sequentially arranged along the first direction X, and only the arrangement order of the micro switch 7, the fixed contact 4 and the moving contact 5 along the first direction X is described here, and are not necessarily located on the same straight line. The fixed contact 4 is fixedly arranged on the shell 1 and is positioned on one side of the moving contact 5 facing the micro switch 7, and the fixed contact 4 is arranged opposite to the moving contact 5, so that the moving contact 5 can be contacted with or separated from the fixed contact 4 when moving along the first direction X. When the fixed contact 4 is in contact with the moving contact 5, the electric conduction of the whole contact mechanism can be realized, which is equivalent to opening the contact mechanism, and when the fixed contact 4 is separated from the moving contact 5, the electric disconnection of the whole contact mechanism is realized, which is equivalent to closing the contact mechanism. The contact mechanism further comprises a circuit board, an electronic solid-state switch (not shown in the figure) and a controller (not shown in the figure) are further arranged on the circuit board, the micro switch 7 is electrically connected with the electronic solid-state switch, and then the micro switch 7 can control the on-off of the electronic solid-state switch. The controller is connected with the electromagnetic structure 6 for controlling the action of the electromagnetic structure 6.
Specifically, the linkage member 3 is slidably mounted in the housing 1, and is located between the stationary contact 4 and the microswitch 7. The sliding direction of the linkage 3 is a first direction X, and the linkage 3 includes a first end 31 and a second end 32 aligned along the first direction X. Specifically, the body of the linkage member 3 may be rod-shaped, and the first end 31 and the second end 32 may be understood as two ends of the rod-shaped linkage member 3. The first end 31 is connected with the moving contact 5, so that when the linkage member 3 slides along the first direction X, the moving contact 5 can be driven to move along the first direction X, and then the contact and separation between the fixed contact 4 and the moving contact 5 can be realized. The second end 32 is directed towards the microswitch 7 so that the microswitch 7 can be switched on or off when the linkage 3 is slid in the first direction X. Specifically, referring to fig. 1, the linkage member 3 slides along the first direction X towards the micro switch 7, so as to drive the moving contact 5 to contact with the fixed contact 4, so that the contact mechanism is electrified and the micro switch 7 can be turned on to turn on the contact mechanism, and conversely, the linkage member 3 slides along the first direction X away from the micro switch 7, so as to drive the moving contact 5 to separate from the fixed contact 4, and turn off the micro switch 7 and turn off the contact mechanism. In addition, the electromagnetic structure 6 is also in transmission connection with the linkage member 3, and can also be used for driving the linkage member 3 to slide along the first direction X so as to control the opening and closing of the contact mechanism. Specifically, the electromagnetic structure 6 is connected with the controller, so that remote control of the contact mechanism can be realized. In the scheme, the linkage of the on-off of the moving contact 5 and the fixed contact 4 and the on-off of the electronic solid state switch is realized by using the linkage piece 3, and the structure is simpler. The present application may have a visible breakpoint relative to a contact mechanism having only an electronic solid state switch.
In a specific embodiment, the contact mechanism may further include an operating member 2, where the operating member 2 is in driving connection with the linkage member 3, and is used to drive the linkage member 3 to slide along the first direction X, so that the contact mechanism can be manually controlled to be opened and closed in a short distance. Therefore, the scheme can realize two control modes of manual operation and remote control of the contact mechanism, and the structure of the contact mechanism is simpler.
With continued reference to fig. 1, when the moving contact 5 is specifically provided, the moving contact 5 may be connected to the linkage member 3 through the elastic member 8, so that the elastic member 8 may absorb a part of the stroke, thereby reducing the installation accuracy and being beneficial to reducing the cost. In addition, by making the stroke of the linkage member 3 for driving the contact mechanism to open be larger than the distance between the fixed contact 4 and the moving contact 5 in the opened state of the contact mechanism, the fixed contact 4 and the moving contact 5 can be reliably connected when the contact mechanism is opened.
Fig. 3a to 3c are schematic views illustrating an opening process of a contact mechanism in an embodiment of the present application, referring to fig. 3a, in a specific embodiment, when the contact mechanism is in an off state, a distance a between an end surface of the second end 32 of the linkage member 3 and an end surface of the micro switch 7 facing the second end 32 in an on state is greater than a distance b between the fixed contact 4 and the movable contact 5. That is, the stroke of the linkage member 3 for triggering the contact of the fixed contact 4 and the movable contact 5 is smaller than the stroke of the linkage member 3 for triggering the opening of the micro switch 7. Then, the linkage rod slides along the direction towards the micro switch 7 in the process of opening the contact mechanism, so that the fixed contact 4 is contacted with the movable contact 5, as shown in fig. 3b, at the moment, the micro switch 7 is not yet opened, and then, the linkage piece 3 continues to slide towards the micro switch 7, and as the movable contact 5 is connected with the linkage piece 3 through the elastic piece 8, the linkage piece 3 can continue to slide, the connection effect of the movable contact 5 and the fixed contact 4 can be improved, and then, the micro switch 7 is triggered, so that the electronic solid-state switch is opened, as shown in fig. 3 c. Of course, when the contact mechanism is opened, the electronic solid-state switch is opened first, and then the moving contact 5 and the fixed contact 4 are opened. The scheme can realize arc extinction by utilizing a simple structure.
With continued reference to fig. 1 and 3a to 3c, in order to realize the driving connection between the operating member 2 and the linkage member 3, the contact mechanism further includes a driving member, the driving member includes a limiting slot 21, the limiting slot 21 includes a first wall 211 and a second wall 212 arranged along the first direction X, and the linkage member 3 includes a protrusion 33, where the protrusion 33 extends into the limiting slot 21. The transmission member is connected to the operating member 2 such that the operating member 2 can drive the transmission member to slide in the first direction X. When the transmission member slides along the first direction X, the first wall surface 211 or the second wall surface 212 of the limiting groove 21 can abut against the protrusion 33, so that the transmission member 3 can be driven to slide along the first direction X.
