When the controller needs to output a level signal to an external interface, one output signal needs at least two interfaces, one is an interface of a reference level, and the other is an interface of an output level. For a circuit breaker with N signals needing to be output, 2N interfaces are needed under the condition that an output level signal has no common end; in case of a common terminal for the output level signals, N +1 interfaces are required. The existing controller is large in size and cannot be installed in a small space due to excessive interfaces, and user experience is also poor.

A first interface 140 and a second interface 150 are provided on the housing 110 as ports through which the controller 100 outputs a specific function.
Specifically, each functional element 120 includes an output terminal 121 and a reference terminal 122, the output terminals 121 of all the functional elements 120 are connected to the selection component 130, and the selection component 130 is connected to the first interface 140; the reference terminals 122 of all the functional elements 120 are electrically connected to the second interface 150, and the reference terminals 122 of the functional elements 120 are directly electrically connected to the second interface 150 or electrically connected to the second interface 150 through other conductive elements, which is not limited herein. The selection component 130 selects the output end 121 of one of the functional elements 120 to communicate with the first interface 140, disconnects the output ends 121 of the other functional elements 120 from the first interface 140, and connects the first interface 140 and the second interface 150 to the external interface 200, so that the output of the single function of the controller 100 can be realized.
As described above, the controller 100 includes the housing 110, the selection component 130 and the at least two functional elements 120 disposed in the housing 110, and the first interface 140 and the second interface 150 disposed on the housing 110, the functional element 120 includes the output end 121 and the reference end 122, the output end 121 of the functional element 120 is electrically connected to the first interface 140 through the selection component 130, the reference end 122 is electrically connected to the second interface 150, the first interface 140 and the second interface 150 are respectively electrically connected to the external interface 200, and the selection component 130 is configured to select one functional element 120 among the at least two functional elements 120 to be electrically connected to the external interface 200. The controller 100 is added with the selection component 130, and one of the at least two functional elements 120 is selected by the selection component 130 to be connected to the external interface 200, so that the port multiplexing is realized, the number of output interfaces is reduced, and the miniaturization design of the controller 100 and the improvement of the user experience are facilitated.
Optionally, in an implementable manner of the embodiment of the present invention, the selecting assembly 130 includes a first selecting element 132 and at least two first access elements 131, the first access elements 131 are configured to be electrically connected to the output ends 121 of the functional elements 120, respectively, one end of the first selecting element 132 is electrically connected to one of the at least two first access elements 131, and the other end is electrically connected to the first interface 140.
The selection assembly 130 comprises a first selection element 132 and two or more first access elements 131, the output 121 of each functional element 120 being electrically connected to one of the first access elements 131, the first selection element 132 being electrically connected to the first interface 140. The first selection element 132 selects one of the two or more first incoming elements 131 to be electrically connected thereto and is disconnected from the other first incoming elements 131 to implement an output of a single function of the controller 100.
Optionally, in an implementation manner of the embodiment of the present invention, the number of the first access components 131 is not less than the number of the functional components 120.
The number of first access elements 131 is greater than or equal to the number of functional elements 120 to ensure that the output 121 of each functional element 120 can be electrically connected to one first access element 131. When the number of the first access components 131 is equal to the number of the functional components 120, the first access components 131 are connected with the functional components 120 in a one-to-one correspondence manner; when the number of the first access components 131 is greater than the number of the functional components 120, a part of the first access components 131 is connected to the functional components 120 in a one-to-one correspondence manner, and another part of the first access components 131 is in an idle state and does not participate in the output of the functions of the controller 100.
Alternatively, in an implementation manner of the embodiment of the present invention, the number of the first selecting elements 132 includes one, and the number of the first accessing elements 131 is the same as the number of the functional elements 120.
The number of the first selecting elements 132 is the same as that of the functional elements 120, the output ends 121 of at least two of the functional elements 120 are connected to at least two of the first accessing elements 131 in a one-to-one correspondence manner, and the first selecting element 132 selects one of the first accessing elements 131 to connect with it.
Of course, the number of the first access components 131 may also be greater than the number of the functional components 120, so that when a new functional component 120 is added into the housing 110, the output end 121 of the new functional component 120 can be directly connected to the first access component 131 which is idle before, without replacing the selection component 130.
Referring to fig. 1 and fig. 3, in an alternative implementation manner of the embodiment of the present invention, the reference terminals 122 of at least two functional elements 120 are electrically connected to the second interface 150.
In this embodiment, each of the functional elements 120 has a common terminal, and the reference terminals 122 of two or more functional elements 120 are all directly electrically connected to the second interface 150. When the function is output, only one of the output ends 121 of the at least two functional elements 120 needs to be selected by the selection component 130 to be electrically connected with the first interface 140.
Taking two or three functional elements 120 as an example for explanation, referring to fig. 1, when two functional elements 120 are included and two functional elements 120 have a common end, the first access element 131 includes at least two, the output ends 121 of the two functional elements 120 are respectively electrically connected to different first access elements 131, and the reference end 122 is simultaneously electrically connected to the second interface 150; one end of the first selection element 132 is electrically connected to the first interface 140, and the other end of the first selection element is electrically connected to one of the two first access elements 131 connected to the output end 121 of the functional element 120, and at this time, the first interface 140 and the second interface 150 are connected to the external interface 200, so that the output of the single function of the controller 100 can be realized. By electrically connecting the first selection element 132 to another first access element 131, an output of another function of the controller 100 can be realized. Referring to fig. 3, when the functional elements 120 include three functional elements 120 and the three functional elements 120 have a common port, the first access elements 131 include at least three functional elements, the output ports 121 of the three functional elements 120 are electrically connected to different first access elements 131, respectively, and the reference port 122 is electrically connected to the second interface 150 at the same time; one end of the first selection element 132 is electrically connected to the first interface 140, and the other end of the first selection element selects one of the three first access elements 131 connected to the output end 121 of the functional element 120 to be electrically connected to the first access element, and at this time, the first interface 140 and the second interface 150 are connected to the external interface 200, so that the output of the single function of the controller 100 can be realized. By electrically connecting the first selection element 132 to the other first access elements 131, the output of other functions of the controller 100 can be realized.
Referring to fig. 2 and fig. 4, in an optional manner, in an implementation manner of the embodiment of the present invention, the selecting assembly 130 further includes a second selecting element 134 and at least two second access elements 133, the second access elements 133 are configured to be electrically connected to the reference terminals 122 of the functional elements 120, respectively, one end of the second selecting element 134 is electrically connected to one of the at least two second access elements 133, and the other end is electrically connected to the second interface 150.
In this embodiment, each functional element 120 does not have a common port, the reference ports 122 of two or more functional elements 120 need to be connected to the second interface 150 respectively, and only one reference port 122 is communicated with the second interface 150 at a time. Specifically, the selecting assembly 130 further includes a second selecting element 134 and two or more second access elements 133, the reference terminal 122 of each functional element 120 is electrically connected to one of the second access elements 133, and the second selecting element 134 is electrically connected to the second interface 150. The second selection element 134 selects one of the two or more second access elements 133 to be electrically connected thereto and is disconnected from the other second access elements 133 to implement an output of a single function of the controller 100.
It will be appreciated that the first selection element 132 and the second selection element 134, when selecting the first access element 131 and the second access element 133 electrically connected thereto, should ensure that the output 121 and the reference 122 of the same functional element 120 are electrically connected to the first interface 140 and the second interface 150 through the selection assembly 130. In order to prevent the selection error, for example, at least two functional elements 120 are arranged in sequence, and accordingly, the first access element 131 and the second access element 133 are also arranged in sequence, the output end 121 and the reference end 122 of at least two functional elements 120 are sequentially connected to the first access element 131 and the second access element 133 in sequence, and the first selection element 132 and the second selection element 134 are associated to rotate synchronously, so that the first selection element 132 and the second selection element are prevented from being connected to the output end 121 and the reference end 122 of different functional elements 120.
Taking the example that the functional elements 120 include two or three as an example, referring to fig. 2, when the functional elements 120 include two functional elements 120 and the two functional elements 120 do not have a common terminal, the first access elements 131 include at least two, the output terminals 121 of the two functional elements 120 are respectively electrically connected to different first access elements 131, the second access elements 133 also include at least two, and the reference terminals 122 of the two functional elements 120 are respectively electrically connected to different second access elements 133.

At this time, the first interface 140 and the second interface 150 are connected to the external interface 200, so that the output of the single function of the controller 100 can be realized. The output of another function of the controller 100 can be realized by electrically connecting the first selection element 132 to another first access element 131 and electrically connecting the second selection element 134 to another second access element 133. Referring to fig. 4, when the functional elements 120 include three functional elements 120 and the three functional elements 120 do not have a common port, the first access elements 131 include at least three functional elements 120, the output ports 121 of the three functional elements 120 are electrically connected to different first access elements 131, the second access elements 133 also include at least three functional elements 120, and the reference ports 122 of the three functional elements 120 are electrically connected to different second access elements 133.

At this time, the first interface 140 and the second interface 150 are connected to the external interface 200, so that the output of the single function of the controller 100 can be realized. The first selection element 132 is electrically connected to the other first access element 131, and the second selection element 134 is electrically connected to the other second access element 133, so that the output of other functions of the controller 100 can be realized.
Optionally, in an implementation manner of the embodiment of the present invention, the number of the second access components 133 is not less than the number of the functional components 120.
The number of second access elements 133 is greater than or equal to the number of functional elements 120 to ensure that the reference end 122 of each functional element 120 is electrically connectable with one second access element 133. When the number of the second access components 133 is equal to the number of the functional components 120, the second access components 133 are connected with the functional components 120 in a one-to-one correspondence; when the number of the second access components 133 is greater than the number of the functional components 120, a part of the second access components 133 is connected to the functional components 120 in a one-to-one correspondence manner, and another part of the second access components 133 is in an idle state and does not participate in the output of the functions of the controller 100.
Alternatively, in an implementation manner of the embodiment of the present invention, the number of the second selecting elements 134 includes one, and the number of the second accessing elements 133 is the same as the number of the functional elements 120.
The number of the second selecting elements 134 is the same as that of the functional elements 120, the reference terminals 122 of at least two of the functional elements 120 are connected to at least two of the second accessing elements 133 in a one-to-one correspondence, and the second selecting element 134 selects one of the second accessing elements 133 to connect with it.
Of course, the number of the second access components 133 may also be greater than the number of the functional components 120, so that when a new functional component 120 is added to the housing 110, the reference end 122 of the new functional component 120 can be directly connected to the second access component 133 that was previously idle, without replacing the selection component 130.
Alternatively, in an implementation manner of the embodiment of the present invention, the selecting component 130 is a device with a switch function, and the first interface 140 and the second interface 150 are respectively one of a connector, a wire, a light emitting diode, or a metal contact.
The selection component 130 may be a device with a switch function, such as an existing mechanical knob switch, a dial switch, an analog switch chip, or a device with a switch function, such as a transistor, a MOS transistor, a logic chip, or a single chip. The first interface 140 and the second interface 150 may also be existing connectors, wires, light emitting diodes, or metal contacts.
