Conventional electric operators do not have the ability to process digital signals and their actions cannot be directly controlled by the host computer. Therefore, in order to realize the remote control function of circuit breakers through electric operators, an additional communication backpack must be added. The function of this backpack is to convert the digital signal of the circuit breaker controller into a switch signal that can be recognized by the electric operator.

[0003] Traditional communication backpacks are connected to electric controls and circuit breakers through wires. The communication backpack is an independent part placed next to the circuit breaker. Since there are 8 connected wires and 2 power cords, the wiring harness inside the switch frame is very messy, causing trouble for installation and maintenance personnel. Utility Model Content

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0024] Reference Figure 1-6 As shown,

[0025] An expansion module for a switch device comprises a shell 1 and a circuit board 2 arranged in the shell 1; a connector 3 is arranged on the shell 1, and the connector 3 is used to cooperate with the switch device to form an electrical connection, and the circuit board 2 forms a communication connection with the switch device through the connector 3; a snap-on component 4 is also arranged on the shell 1, and the snap-on component 4 is used to cooperate with the switch device to form a snap connection so as to install the shell 1 on the switch device.

[0026] The expansion module can be a circuit module used to provide remote control function as mentioned in the background technology, or it can be a circuit module used to realize collection and transmission. The specific requirements can be selected according to the needs of technical personnel in this field. This solution does not design the specific structure and improvement of the circuit module.

[0027] The expansion module in this solution is plugged into the switch device through the connector 3 to form an electrical connection, for example, by using a socket and a female connector for plugging. The specific connector 3 can be set as a socket or a female connector according to needs. After the connector 3 is plugged into the switch device, it can provide a positioning function, so that the clamping component 4 can more conveniently form a clamping fit with the switch device. The clamping generally requires the cooperation of a hook and a block to form a clamping fit, so position correspondence is also required to complete the clamping action. The connector 3 in this solution can provide positioning by plugging into the switch device.

[0028] It should also be noted that the switch device may be any type of switch component that requires remote on and off control, such as a circuit breaker.

[0029] The expansion modules are easy to install and can be selected as needed, so they are also convenient for users to use and can be purchased according to actual needs, thereby reducing costs.

[0030] In the above embodiment, preferably, the connecting member 3 protrudes from the surface of the housing 1 and is used to be inserted into the switch device.

[0031] Combined with the above-mentioned embodiment, it is equivalent to that the connector 3 adopts a plug-in structure (refer to Figure 2 , 3As shown in the figure), the female header is located on the switch device, and the switch device without the expansion module will not have any raised parts, which can keep the surface of the switch device smoother. Since the female header is located on the switch device, if a better dustproof effect is required, a sealing plug can be used to seal the female header.

[0032] The specific clamping assembly 4 can be configured according to the following scheme:

[0033] The snap-on assembly 4 includes a pressing portion 41 and a snap-on portion 42; the pressing portion 41 is connected to the housing 1, and the housing 1 has a space for the pressing portion 41 to be pressed and deformed, and the pressing portion 41 has elastic force so as to be deformed when pressed or to restore when no force is applied; the snap-on portion 42 is located on the pressing portion 41, and the snap-on portion 42 cooperates with the switch device to form or release the snap-on connection through the deformation or restoration of the pressing portion 41.

[0034] The pressing portion 41 is used to cooperate with the fingers to press. By pressing the pressing portion 41 with the fingers, the pressing portion 41 is deformed, and the pressing portion 41 moves the position of the clamping portion 42 through the deformation. At this time, the clamping portion 42 and the switching device can be released from the clamping connection. At this time, the connecting piece 3 can be pulled out of the switching device with force (that is, the socket is pulled out from the mother socket), thereby separating the expansion module and the switching device.

[0035] During installation, the pressing portion 41 can be pressed by hand to move the snap-fitting portion 42, making it easier for the snap-fitting portion 42 to cooperate with the switch device. After the pressing portion 41 is released, the pressing portion 41 can be restored by elastic force, and the snap-fitting portion 42 can now cooperate with the switch device.

[0036] Of course, depending on the structure, the pressing portion 41 may not be pressed during installation. Figure 2 and 3 As shown in the figure, the switch device has a guiding inclined surface, and the clamping portion 42 is provided with an inclined surface that cooperates with the guiding inclined surface. At this time, when the expansion module is installed on the switch device, it is only necessary to move the shell 1 toward the switch device so that the inclined surface on the clamping portion 42 can cooperate with the guiding inclined surface on the switch device. As the pressure increases, the guiding inclined surface can guide the pressing portion 41 to deform. After the clamping portion 42 is in place, the pressing portion 41 releases the elastic force and recovers, so that the clamping portion 42 and the switch device are clamped.

[0037] In a specific configuration, the connector 3 and the snap-in assembly 4 are located at two sides of the housing 1 or close to two sides (see Figure 2 The upper clamping component 4 and the lower connecting piece 3 are distributed).

[0038] When the housing 1 is installed with the switch device, the connector 3 is first plugged into the switch device, and then the snap-fit ​​assembly 4 is snap-fitted into the switch device. The plugging and snap-fitting are located on both sides of the housing 1 or near both sides, which is equivalent to connecting both sides of the housing 1 or near both sides with the switch device, thus making the connection more stable.

[0039] Of course, in a further configuration, the number of the clamping components 4 is at least two, and the two clamping components 4 are located on both sides of the housing 1 .

[0040] If there are two clamping assemblies 4, they can be installed on both sides of the housing 1 accordingly. When pressing, the two clamping assemblies 4 can be operated at the same time, that is, the two pressing parts 41 are pressed at the same time, and the two clamping parts 42 are disconnected from the switch device at the same time. This arrangement makes the clamping connection more stable and also facilitates removal.

[0041] The above embodiment describes the structure of an expansion module of a switch device. The switch device is specifically exemplified as a circuit breaker, and the expansion module is installed on the circuit breaker, and the installation method adopts the above-mentioned clamping method.

[0042] More specifically, a clamping piece 5 for engaging with the clamping component 4 is provided at a position corresponding to the clamping component 4 of the circuit breaker. The clamping piece 5 is engaged with the clamping component 4, and specifically, the clamping piece 5 can be formed by digging a hole on the surface of the circuit breaker. After the hole is dug, the clamping piece 5 for the clamping part 42 to engage can be formed. The clamping principle is as follows: after the clamping part 42 passes through the dug hole, the pressing part 41 releases the elastic force to restore, and at this time the clamping part 42 will engage with the opening of the dug hole, for example, the clamping part 42 adopts a hook structure. In the specific setting, the edge of the outer surface corresponding to the opening of the dug hole can be provided with a guide slope (refer to Figure 2 , 3 As shown in the figure, the guiding inclined surface cooperates with the inclined surface at the corresponding position of the clamping part 42 for guiding, and the inclined surface of the clamping part 42 and the guiding inclined surface of the hole dug on the circuit breaker are squeezed, so that the pressing part 41 can be deformed, accumulate elastic potential energy, and recover after the clamping part 42 passes through the dug hole, so that the clamping part 42 and the clamping member 5 are clamped. The clamping member 5 in this solution can be a part of the circuit breaker housing, that is, the edge of the dug hole is used to cooperate with the clamping part 42 (for example, a hook, refer to Figure 3 , 5 , 6) for clamping.

[0043] In a further configuration, a first groove 61 is provided on the surface of the circuit breaker corresponding to the housing 1, and a second groove 62 is provided on the housing 1 at a position corresponding to the first groove 61, and the second groove 62 and the first groove 61 are combined to form a channel for screws to pass through; an assembly hole for fitting with the screw is provided at a position corresponding to the channel on the circuit breaker, and the assembly hole corresponds to the position of the channel.

[0044] The combination of the first groove 61 and the second groove 62 can be used to guide the screw assembly, and has a guiding effect, so that the tip of the screw is placed toward the channel (refer to Figure 1 , 2 As shown in the figure, the screw can be inserted into the corresponding assembly hole under the guidance of the channel, and then a screwdriver or other screw-tightening tool can be inserted into the channel to drive the screw to rotate, thereby achieving rapid assembly. Therefore, even if the optional expansion module is installed, it will not affect the installation of the screw, and can even provide a guiding effect, making it easier to align the screw with the assembly hole.

[0045] Of course, as a further preferred embodiment, the channel formed by the combination of the first groove 61 and the second groove 62 is cylindrical. The cylindrical channel can guide the screw better and can better fit the shape of the screw.

[0046] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
