[0060] The "multiple" mentioned in the embodiments of this application refers to two or more.

[0061] like Figure 1 As shown, the power electronic device 100 provided in this application embodiment includes: a circuit board 10, a switching device 20, and a housing 30.

[0062] Circuit board 10 can be part of the power electronic module in power electronic device 100. It is understood that the power electronic module includes circuit board 10 and electronic components electrically connected to circuit board 10. The type of power electronic module depends on the type of power electronic device 100. For example, power electronic device 100 can be a power conversion device, which also includes a power conversion module, a form of power electronic module. The power conversion device can be an inverter, energy storage converter, DC-DC converter, etc. In practice, power electronic devices can also be other devices, such as switching power supplies, uninterruptible power supplies, etc., and are not limited to power conversion devices.

[0063] The box 30 may include a box body 31 and a box cover 32. The box body 31 has an opening, and the box cover 32 covers the box body 31 and closes the opening, so that the box body 31 and the box cover 32 cooperate to form a closed cavity.

[0064] The switch device 20 is installed in the enclosure 30, and at least a portion of the switch device 20 is located inside the enclosure 30. The switch device 20 can be used to control the switching on and off of DC power, for example, the switch device 20 can be used to control the opening and closing of the power electronic module of the power electronic device 100.

[0065] In this embodiment of the application, the switching device 20 includes a first switch portion 21 located inside the housing 30.

[0066] In some embodiments, the switching device 20 may further include a second switch portion 22 connected to the first switch portion 21. The second switch portion 22 includes a switch operation section 22a configured to control the on / off state of the switching device 20.

[0067] As mentioned above, the switch device 20 is installed in the housing 30, which can be understood as follows: the first part 21 of the switch is directly installed in the housing 30, and the second part 22 of the switch is indirectly installed in the housing 30 through the first part 21 of the switch; or, the second part 22 of the switch is directly installed in the housing 30, and the first part 21 of the switch is indirectly installed in the housing 30 through the second part 22 of the switch; or, both the first part 21 of the switch and the second part 22 of the switch are directly installed in the housing 30.

[0068] The second part 22 of the switch can be located inside or outside the housing 30. For ease of operation of the switch device 20, the second part 22 of the switch is located outside the housing 30.

[0069] The switching device 20 can be a rotary switch, and the switch operation part 22a can be a knob. In practice, the switching device 20 can also be a push-button switch or other types of switches, and this application embodiment does not limit this.

[0070] The circuit board 10 is installed inside the housing 30. The circuit board 10 can be a printed circuit board or other types.

[0071] The circuit board 10 and the first part of the switch 21 are distributed along a first direction. To facilitate the installation of the circuit board 10 and the first part of the switch 21, the first direction is perpendicular to the circuit board 10, and the first direction is the distribution direction of the main body 31 and the cover 32. In practice, the first direction can also be perpendicular to the distribution direction of the main body 31 and the cover 32.

[0072] The circuit board 10 includes a circuit board body 11 and a board-side connector 12 disposed on the circuit board body 11; wherein the board-side connector 12 is conductive, the board-side connector 12 is electrically connected to the circuit board body 11, or the board-side connector 12 is electrically connected to electronic components on the circuit board body 11, and the first direction is perpendicular to the circuit board body 11.

[0073] It is understandable that the circuit board 10 has a built-in board-side connector 12. The board-side connector 12 can be installed on the circuit board body 11 by means of welding, crimping or riveting.

[0074] The first part of the switch 21 has a first switch side 217 facing the circuit board 10 in the first direction. The first part of the switch 21 has a switch side connector 211 on the first switch side 217. The switch side connector 211 and the circuit board side connector 12 are electrically connected to the first part of the switch 21 and the circuit board 10 through plug-in or mating. The circuit board 10 is installed in the housing 30 through the electrical connection with the first part of the switch 21.

[0075] The aforementioned first part 21 of the switch has a built-in switch-side connector 211. The switch-side connector 211 and the housing 213 of the first part 21 of the switch can be an integral structure, thereby simplifying the structure of the switch device 20. Of course, the switch-side connector 211 and the housing 213 of the first part 21 of the switch can also be separate structures.

[0076] The switch-side connector 211 of the first part 21 of the switch can be one or more. The number of board-side connectors 12 of the circuit board 10 corresponds to the number of switch-side connectors 211 to meet the different power supply requirements of the power electronic equipment.

[0077] In the above structure, the switch-side connector 211 and the board-side connector 12 are connected by plug-in or mating to achieve electrical connection between the first part 21 of the switch and the circuit board 10, thereby achieving electrical connection between the switch device 20 and the circuit board 10, and further achieving electrical connection between the device to be controlled (e.g., power electronic module) on the circuit board 10 and the switch device 20, thereby enabling the switch device 20 to control the on / off state of the device to be controlled.

[0078] The assembly method of the switching device 20 in the power electronic device 100 provided in this application embodiment is as follows:

[0079] like Figure 2 As shown, open the housing 30 (e.g., separate the housing cover 32 and the housing body 31), fix the switch device 20 to the housing 30, and the first switch part 21 of the switch device 20 is located inside the housing 30; place the circuit board 10 inside the housing 30, the circuit board 10 is located on one side of the first switch part 21 in the first direction, and the circuit board 10 faces the first switch side 217 of the first switch part 21, and then align the board side connector 12 on the circuit board 10 with the switch side connector 211 of the first switch part 21;

[0080] Movable circuit board 10, for example, such as Figure 2 Move the circuit board 10 in the installation direction shown (from top to bottom along the first direction) so that the board-side connector 12 and the switch-side connector 211 are connected by plug-in or mating, thereby realizing the electrical connection between the circuit board 10 and the first part 21 of the switch. This also realizes the electrical connection between the switch device 20 and the circuit board 10, and allows the circuit board 10 to be installed in the housing 30 through the electrical connection with the first part 21 of the switch.

[0081] As can be seen from the above installation method, the circuit board 10 has a board-side connector 12, and the first part of the switch 21 has a switch-side connector 211. By plugging or mating the board-side connector 12 and the switch-side connector 211, the circuit board 10 and the switch device 20 can be electrically connected. Compared with making wires and connecting the circuit board and the switch device to wires respectively, the assembly efficiency of the switch device 20 is improved.

[0082] In the power electronic device 100 provided in this application embodiment, the board-side connector 12 and the switch-side connector 211 are not wires, so there is no need to make wires, which reduces the amount of wires used and reduces the cost of the power electronic device 100.

[0083] In this embodiment of the application, the switch-side connector 211 and the board-side connector 12 are plugged in or mated together, indicating that the connection between the switch-side connector 211 and the board-side connector 12 does not include welding.

[0084] Because the switching device 20 is relatively large, and the first part 21 of the switch is also relatively large, it is difficult to solder the entire first part 21 of the switch to the circuit board 10. In the power electronic device 100 provided in this application embodiment, since the circuit board 10 is installed in the housing 30 through an electrical connection with the first part 21 of the switch, the first part 21 of the switch can be installed in the housing 30 first, and then the circuit board 10 can be electrically connected to the switching device 20 in the housing 30 by plugging or mating. This reduces the assembly difficulty of the first part 21 of the switch and the circuit board 10, thereby reducing the assembly difficulty of the switching device 20 and the circuit board 10 and improving the assembly efficiency of the switching device 20.

[0085] In the case where the switching device 20 also includes a second switch portion 22 located outside the housing 30, and the first switch portion 21 and the circuit board 10 are assembled and placed inside the housing 30, the second switch portion 22 outside the housing 30 needs to be connected to the first switch portion 21 inside the housing 30. Since the first switch portion 21 has the circuit board 10, the circuit board 10 will interfere with the connection between the second switch portion 22 and the first switch portion 21, increasing the difficulty of connecting them and reducing their connection efficiency. In the power electronic device 100 provided in this application embodiment, since the circuit board 10 is installed inside the housing 30 through an electrical connection with the first switch portion 21, the first switch portion 21 and the second switch portion 22 can be connected first. This avoids interference from the circuit board 10, reducing the difficulty of connecting the second switch portion 22 and the first switch portion 21, improving their connection efficiency, and thus improving the installation efficiency of the switching device 20.

[0086] In the power electronic device 100 provided in this application embodiment, when the circuit board 10 is installed inside the housing 30 through an electrical connection with the first part 21 of the switch, the circuit board 10 can also be installed inside the housing 30 through other connection structures. This improves the stability of the circuit board 10.

[0087] For example, the circuit board 10 can also be installed inside the housing 30 using connection structures such as snap-fit ​​structures, welding structures, and connecting fasteners.

[0088] It should be noted that the circuit board 10 is first electrically connected to the first part 21 of the switch for installation inside the housing 30; the circuit board 10 is then installed inside the housing 30 through other connection structures.

[0089] In this embodiment, when the board-side connector 12 and the switch-side connector 211 are plugged in, the plugging of the board-side connector 12 and the switch-side connector 211 can be separated for ease of maintenance; when the board-side connector 12 and the switch-side connector 211 are mated in, the mating of the board-side connector 12 and the switch-side connector 211 can be separated for ease of maintenance.

[0090] In the power electronic device 100 provided in this application embodiment, the circuit board 10 is installed in the housing 30 through an electrical connection with the first part 21 of the switch. To facilitate the installation of the circuit board 10 and improve its stability, the first part 21 of the switch is provided with a support surface 212. At least one of the board-side connector 12 and the circuit board body 11 is in contact with the support surface 212 in a first direction. In this way, the support surface 212 can support the circuit board 10, improving its stability; moreover, the circuit board 10 can be placed on the support surface 212, facilitating its installation.

[0091] For example, the support surface 212 and the board-side connector 12 are attached in a first direction; or, the support surface 212 and the circuit board body 11 are attached in a first direction; or, the support surface 212 can be of two types, one of which is attached to the circuit board body 11 in a first direction, and the other of which is attached to the board-side connector 12 in a first direction.

[0092] The specific connection structure of the board-side connector 12 and the switch-side connector 211 is described below.

[0093] In some embodiments, when the switch-side connector 211 and the board-side connector 12 are plugged into each other, the switch-side connector 211 and the board-side connector 12 can be plugged into each other along a first direction. This can be understood as the plugging direction of the switch-side connector 211 and the board-side connector 12 being the first direction. When the switch-side connector 211 and the board-side connector 12 are mated together, the switch-side connector 211 and the board-side connector 12 can be mated together along a first direction. This can be understood as the mating direction of the switch-side connector 211 and the board-side connector 12 being the first direction. Since the circuit board 10 and the first part 21 of the switch are distributed along the first direction, the switch-side connector 211 and the board-side connector 12 can be plugged in or mated together along the first direction, which facilitates the movement of the circuit board 10 and the connection between the switch-side connector 211 and the board-side connector 12. Moreover, the distribution direction of the circuit board 10 and the first part 21 of the switch is the same as the movement direction of the circuit board 10, which can reduce the space required to move the circuit board 10, facilitate the reduction of the space of the entire housing 30, and help improve the integration of power electronic equipment.

[0094] In practice, the switch-side connector 211 and the board-side connector 12 can also be inserted or mated in other directions. For example, the switch-side connector 211 and the board-side connector 12 can also be inserted or mated in a direction perpendicular to the first direction. The direction perpendicular to the first direction can be a second direction or a third direction, wherein the second direction is perpendicular to the third direction.

[0095] like Figure 3 and Figure 4 As shown, the board-side connector 12 and the switch-side connector 211 are plugged into each other, thus achieving electrical connection between the first part 21 of the switch and the circuit board 10 through the plugging and mating of the switch-side connector 211 and the board-side connector 12. To facilitate the plugging and mating of the board-side connector 12 and the switch-side connector 211, the board-side connector 12 includes a conductive plug 123, and the switch-side connector 211 has a socket 2115. The socket 2115 and the conductive plug 123 are electrically connected through the plugging and mating of the conductive plug 123. In this way, the conductive plug 123 can be directly aligned with the socket 2115 and inserted into the socket 2115. The conductive plug 123 and the socket 2115 are easily aligned, thereby simplifying the connection between the circuit board 10 and the switching device 20.

[0096] In the above-described plug-in structure, the conductive plug 123 and the socket 2115 can be plugged in along the first direction or along other directions. For an explanation of the plugging direction, please refer to the previous text.

[0097] like Figure 4 As shown, in the above-described plug-in structure, when the socket 2115 and the conductive plug 123 are plugged in along the first direction, at least one of the first switch-side connecting end face 2113 of the switch-side connector 211 and the bottom wall 21154 of the socket 2115 can form a support surface 212. For example, the first switch-side connecting end face 2113 of the switch-side connector 211 forms the support surface 212; or, the bottom wall 21154 of the socket 2115 forms the support surface 212; or, the first switch-side connecting end face 2113 of the switch-side connector 2111 forms the support surface 212, and the bottom wall 21154 of the socket 2115 also forms the support surface 212.

[0098] To facilitate the formation of the support surface 212, the insertion hole 2115 is a blind hole. Thus, the insertion hole 2115 has a bottom wall 21154, which forms the support surface 212. The support surface 212 formed by the bottom wall 21154 can fit against the conductive plug 123 in the first direction. In this way, the support surface 212 indirectly supports the circuit board body 11 by supporting the conductive plug 123, thereby achieving support for the entire circuit board 10 and improving its stability. Furthermore, the support surface 212 also acts as a limiting element for the circuit board 10, facilitating its installation.

[0099] The first switch-side connection end face 2113 of the switch-side connector 211 is the end face of the switch-side connector 211 that is close to the circuit board body 11 along the first direction. In order for the first switch-side connection end face 2113 to form a support surface 212, the structure of the board-side connector 12 needs to be adjusted. The board-side connector 12 further includes a board-side connecting section 124, which electrically connects the circuit board body 11 and the conductive plug 123. The board-side connecting section 124 and the conductive plug 123 are distributed along a first direction. The board-side connecting section 124 has a first board-side connecting end face 1241 that connects to the conductive plug 123. In this way, the support surface 212 formed by the first switch-side connecting end face 2113 can fit with the first board-side connecting end face 1241 in the first direction. The support surface 212 can indirectly support the circuit board body 11 by supporting the board-side connecting section 124, thereby achieving support for the entire circuit board 10 and improving the stability of the entire circuit board 10. Moreover, the support surface 212 plays a limiting role for the circuit board 10, which facilitates the installation of the circuit board 10.

[0100] When the insertion direction of the socket 2115 and the conductive plug 123 is other than the direction, the first part 21 of the switch can form a support surface 212 through other structures, such as a support protrusion provided in the first part 21 of the switch, which forms the support surface 212. This application embodiment does not limit this.

[0101] Continue to refer to Figure 4 The socket 2115 includes a first hole segment 21151, which is electrically connected to the conductive plug 123 through a plug-in engagement. It is understood that the wall of the first hole segment 21151 fits against the circumferential sidewall of the conductive plug 123 to ensure electrical connection.

[0102] For ease of insertion, the socket 2115 also includes at least one of the second hole segment 21152 and the third hole segment 21153.

[0103] The second hole segment 21152 and the first hole segment 21151 are distributed along the insertion direction and are connected; the second hole segment 21152 is located at the insertion end 03 of the first hole segment 21151. The insertion end 03 of the first hole segment 21151 is the end of the first hole segment 21151 into which the conductive plug 123 is inserted; the specific direction of the insertion direction can be referred to the previous text.

[0104] The second hole segment 21152 and the conductive plug 123 are guided and engaged. It can be understood that the second hole segment 21152 and the conductive plug 123 have a gap in the radial direction, which is the direction perpendicular to the insertion direction.

[0105] When the socket 2115 includes a first segment 21151 and a second segment 21152, the conductive plug 123 is first inserted into the second segment 21152 and then into the first segment 21151. Under the guidance of the second segment 21152, it is easy for the conductive plug 123 to be inserted into the first segment 21151, thereby facilitating the connection and mating of the conductive plug 123 and the socket 2115, and thus facilitating the connection of the circuit board 10 and the switch device 20.

[0106] The third hole segment 21153 and the first hole segment 21151 are distributed along the insertion direction and are connected; the third hole segment 21153 is located at the insertion end 04 of the first hole segment 21151. The insertion end 04 of the first hole segment 21151 is the end of the first hole segment 21151 from which the conductive plug 123 is inserted; the specific direction of the insertion direction can be referred to the previous text.

[0107] The third hole segment 21153 and the conductive plug 123 are guided and fitted. It can be understood that the third hole segment 21153 and the conductive plug 123 have a gap in the radial direction, which is the direction perpendicular to the insertion direction.

[0108] When the socket 2115 includes a third segment 21153 and a first segment 21151, the conductive plug 123 is first inserted into the first segment 21151 and then into the third segment 21153. When it is necessary to remove the conductive plug 123, the third segment 21153 provides a guiding effect, making it easier to remove the conductive plug 123. At the same time, the third segment 21153 reduces the probability that the conductive plug 123 will be jammed by the first segment 21151.

[0109] When the socket 2115 includes a first hole segment 21151, a second hole segment 21152 and a third hole segment 21153, the first hole segment 21151 is located between the second hole segment 21152 and the third hole segment 21153 along the insertion direction.

[0110] In the above-mentioned plug-in structure, such as Figure 1 and Figure 2 As shown, the outer surface of the switch-side connector 211 has an insulating layer 2116. The outer surface of the switch-side connector 211 does not include the wall of the socket 2115. In this way, the insulating layer 2116 provides insulation protection, reducing the probability of a short circuit caused by accidental contact between the switch-side connector 211 and other conductive components, and improving the safety and reliability of the power electronic equipment.

[0111] The switch-side connector 211 has a conductive portion to ensure electrical connection between the switch-side connector 211 and the board-side connector 12, with the conductive portion and the board-side connector 12 engaging. The conductive portion and the insulating layer 2116 of the switch-side connector 211 can be an integral structure or a separate structure. The housing 213 and the insulating layer 2116 of the first part 21 of the switch can be an integral structure or a separate structure. Alternatively, the conductive portion and the insulating layer 2116 of the switch-side connector 211 can be an integral structure, while the insulating layer 2116 and the housing 213 can be a separate structure or an integral structure; or the conductive portion and the insulating layer 2116 of the switch-side connector 211 can be a separate structure, while the insulating layer 2116 and the housing 213 can be a separate structure or an integral structure.

[0112] In this embodiment, the board-side connector 12 and the switch-side connector 211 can also be connected via other structures. In some embodiments, such as Figures 6-8 As shown, the switch-side connector 211 includes a first connector 2111 and a second connector 2112. The first connector 2111 restricts the insertion cavity 21111, and the second connector 2112 is located inside the insertion cavity 21111. The board-side connector 12 is inserted into the insertion cavity 21111 and abuts against the second connector 2112 to achieve electrical connection.

[0113] In the above structure, the plate-side connector 12 and the second connector 2112 abut against each other in a direction perpendicular to the insertion direction. This can be understood as the abutment direction of the plate-side connector 12 and the second connector 2112 being perpendicular to the insertion direction. For the specific direction of the insertion direction, please refer to the previous text. The first connector 2111 and the second connector 2112 can be an integral structure or a separate structure.

[0114] For example, the insertion direction is the first direction, and the board-side connector 12 and the second connector 2112 can abut in the second direction, which can be understood as: the abutment direction is the second direction; or, the board-side connector 12 and the second connector 2112 can abut in the third direction, which can be understood as: the abutment direction is the third direction.

[0115] In the above-described plug-in structure, the plug-in cavity 21111 has opposing first sidewalls 01 and second sidewalls 02 in the abutment direction. The second connector 2112 is connected to the first sidewall 01 of the plug-in cavity 21111. The plate-side connector 12 is inserted between the second sidewall 02 and the second connector 2112 in the abutment direction. The plate-side connector 12 also abuts against the second sidewall 02 in the abutment direction.

[0116] When the switching device 20 is a DC switch, such as Figure 7As shown, each insertion cavity 21111 contains two second connectors 2112, one of which is connected to the positive terminal of the switching device 20, and the other is connected to the negative terminal of the switching device 20. Alternatively, each insertion cavity 21111 may contain only one second connector 2112, which is electrically connected to both the positive and negative terminals of the switching device 20.

[0117] In the above-mentioned plug-in structure, such as Figure 8 As shown, the first switch-side connecting end face 2113 of the first connector 2111 can form a support surface 212, and the support surface 212 and the circuit board body 11 are in contact in a first direction; wherein, the first switch-side connecting end face 2113 is the end face of the first connector 2111 that is close to the circuit board body 11 along the first direction. In this way, the support surface 212 provides support for the entire circuit board 10, improving the stability of the entire circuit board 10; moreover, the support surface 212 also limits the circuit board 10, facilitating the installation of the circuit board 10.

[0118] In the above structure, the first connector 2111 is fully utilized, eliminating the need for additional components to form the support surface 212, thus simplifying the structure of the switching device 20.

[0119] To facilitate the insertion of the plate-side connector 12, the second connector 2112 is an elastic member, and is configured to deform along the abutment direction of the plate-side connector 12 and the second connector 2112. This can be understood as the second connector 2112 being configured to deform during the insertion of the plate-side connector 12 into the insertion cavity 21111. This facilitates the insertion of the plate-side connector 12 into the insertion cavity 21111; simultaneously, due to the deformation of the second connector 2112, it possesses a restoring force, increasing the abutment force between the second connector 2112 and the plate-side connector 12, and improving the reliability of the abutment between the second connector 2112 and the plate-side connector 12.

[0120] In some embodiments, such as Figure 7 As shown, in the contact direction, the second connector 2112 protrudes from the side away from the plate-side connector 12 toward the side closer to the plate-side connector 12. In this way, the protruding portion 21123 of the second connector 2112 can abut against the plate-side connector, which facilitates the deformation of the second connector 2112.

[0121] For example, the cross-section of the second connector 2112 is arc-shaped and the cross-section of the second connector 2112 is perpendicular to the insertion direction.

[0122] Of course, the second connector 2112 can also be a spring structure or other deformable structure, and is not limited to the above-mentioned structure.

[0123] In practice, other structures can also be used to facilitate the deformation of the second connector 2112. In other embodiments, such as... Figure 7 As shown, in a direction perpendicular to the insertion direction and the abutment direction, the second connector 2112 has a connecting end 21121 and a free end 21122 disposed opposite to each other; wherein, the connecting end 21121 of the second connector 2112 is directly connected to the first connector 2111, for example, the connecting end 21121 of the second connector 2112 is connected to the first sidewall 01 of the insertion cavity 21111; the free end 21122 of the second connector 2112 has a preset distance from the first connector 2111, and the free end 21122 of the second connector 2112 is indirectly connected to the first connector 2111 through the connecting end 21121. It can be understood that the free end 21122 of the second connector 2112 is suspended in the insertion cavity 21111, and the second connector 2112 forms a cantilever structure. This reduces the constraint of the first connector 2111 on the free end 21122 of the second connector 2112, making it easier for the second connector 2112 to deform.

[0124] For example, if the insertion direction is the first direction, the abutment direction is the second direction, and the third direction is perpendicular to the first and second directions, then the second connector 2112 has a connecting end 21121 and a free end 21122 that are relatively arranged in the third direction.

[0125] In practice, the two ends of the second connector 2112 can also be connected to the first connector 2111 in a direction perpendicular to the insertion direction and the contact direction, and are not limited to the above embodiments.

[0126] In practice, the two structures described above that facilitate the deformation of the second connector 2112 can be implemented individually or in combination. To further facilitate the deformation of the second connector 2112, the two structures can be combined. Specifically, in the abutment direction, the second connector 2112 protrudes from the side away from the plate-side connector 12 toward the side closer to the plate-side connector 12; in the direction perpendicular to the insertion direction and the abutment direction, the second connector 2112 has a connecting end 21121 and a free end 21122 that are disposed opposite to each other; wherein, the connecting end 21121 of the second connector 2112 is directly connected to the first connector 2111; the free end 21122 of the second connector 2112 is at a preset distance from the first connector 2111, and the free end 21122 of the second connector 2112 is indirectly connected to the first connector 2111 through the connecting end 21121.

[0127] In the above-described plug-in structure, since the board-side connector 12 and the second connector 2112 are electrically connected through abutment, the second connector 2112 is conductive. Based on this, the first connector 2111 can be an insulating connector. This can be understood as follows: the outer surface of the switch-side connector 211 has an insulating layer 2116, and the first connector 2111 forms the insulating layer 2116. In this way, the first connector 2111 can insulate against the board-side connector 12 and the second connector 2112, achieving insulation protection, reducing the probability of a short circuit caused by accidental contact between the switch-side connector 211 and other conductive components, and improving the safety and reliability of the power electronic equipment.

[0128] It should be noted that the outer surface of the switch-side connector 211 does not include the inner wall of the insertion cavity 21111. The housing 213 and the insulating layer 2116 (first connector 2111) of the first part 21 of the switch can be an integral structure or a separate structure.

[0129] When the first connector 2111 is an insulating connector, the outer surface of the switch-side connector 211 may also have an insulating layer 2116. The insulating layer 2116 covers the outer surface of the first connector 2111, achieving double-layer insulation. The insulating layer 2116 and the first connector 2111 can be an integral structure or a separate structure. The insulating layer 2116 and the housing 213 of the first part 21 of the switch can also be an integral structure or a separate structure. For a description of this part, please refer to the preceding text.

[0130] In this embodiment, the board-side connector 12 and the switch-side connector 211 can also be mated together. In some embodiments, such as Figure 10 and Figure 12 As shown, the board-side connector 12 has a first board-side connecting end 121 and a second board-side connecting end 122 arranged opposite to each other in the mating direction. The first board-side connecting end 121 is connected to the circuit board 10, and the second board-side connecting end 122 is electrically connected to the switch-side connector 211 through a mating fit. This simple mating structure simplifies the overall structure of the power electronic device. The specific direction of the mating can be found in the preceding text.

[0131] In the above embodiments, when the docking direction is the first direction, the surfaces of the switch-side connector 211 and the second board-side connector 122 that dock form a support surface 212, and the end faces of the support surface 212 and the second board-side connector 122 are in contact in the first direction. Specifically, the end face of the switch-side connector 211 near the circuit board body 11 along the first direction is the first switch-side connector end face 2113, which is also the surface of the switch-side connector 211 and the second board-side connector 122 that dock. It can be understood that the first switch-side connector end face 2113 forms the support surface 212.

[0132] In the above structure, the support surface 212 supports the board-side connector 12, thereby supporting the entire circuit board 10, improving the stability of the circuit board 10, and facilitating the installation of the circuit board 10; at the same time, the mating surface forms the support surface 212, making full use of the switch-side connector 211, eliminating the need for a separate structure to form the support surface 212, and simplifying the structure of the switching device 20.

[0133] When the docking direction is other than the first direction, the first part 21 of the switch can form a support surface 212 through other structures, such as a support protrusion provided in the first part 21 of the switch, which forms the support surface 212.

[0134] When the plate-side connector 12 and the switch-side connector 211 are mated together, in order to improve the stability of the electrical connection between the plate-side connector 12 and the switch-side connector 211, the plate-side connector 12 and the switch-side connector 211 can be fixedly connected by fasteners 13. Specifically, the plate-side connector 12 is provided with a first mounting hole 125 that mates with the fastener 13, and the switch-side connector 211 is provided with a second mounting hole 2114 that mates with the fastener 13. Thus, under the action of the fastener 13, the probability of relative movement between the plate-side connector 12 and the switch-side connector 211 is reduced, improving the reliability of the electrical connection; at the same time, the plate-side connector 12 and the switch-side connector 211 can also be electrically connected by the fastener 13, which can increase the allowable current flowing between the plate-side connector 12 and the switch-side connector 211.

[0135] For ease of installation and disassembly, fastener 13 can be a threaded fastener. Of course, fastener 13 can also be a pin or other fasteners; the type of fastener 13 is not limited in this embodiment.

[0136] In the above docking structure, such as Figure 11 As shown, the outer surface of the switch-side connector 211 has an insulating layer 2116. However, the outer surface of the switch-side connector 211 does not include the wall of the second mounting hole 2114, and the mating surfaces of the switch-side connector 211 and the board-side connector 12 do not have the insulating layer 2116. In this way, the insulating layer 2116 provides insulation protection, reducing the probability of a short circuit caused by accidental contact between the switch-side connector 211 and other conductive components, and improving the safety and reliability of the power electronic equipment.

[0137] The switch-side connector 211 has a conductive portion 2117 to ensure electrical connection between the switch-side connector 211 and the plate-side connector 12. The conductive portion 2117 and the plate-side connector 12 are mated together. The conductive portion 2117 and the insulating layer 2116 of the switch-side connector 211 can be an integral structure or a separate structure. The housing 213 and the insulating layer 2116 of the first part 21 of the switch can be an integral structure or a separate structure. Alternatively, the conductive portion 2117 and the insulating layer 2116 of the switch-side connector 211 can be an integral structure, while the insulating layer 2116 and the housing 213 can be a separate structure or an integral structure; or the conductive portion 2117 and the insulating layer 2116 of the switch-side connector 211 can be a separate structure, while the insulating layer 2116 and the housing 213 can be a separate structure or an integral structure.

[0138] In this embodiment, the board-side connector 12 and the switch-side connector 211 can also be connected and fitted through other structures, and are not limited to the above embodiments.

[0139] In this embodiment, when the board-side connector 12 and the switch-side connector 211 are mated or plugged into each other, the first part of the switch 21 and the circuit board body 11 need to be positioned together to facilitate the proper connection of the board-side connector 12. In some embodiments, such as Figure 9 As shown, one of the switch first part 21 and the circuit board body 11 is provided with a positioning member 216, and the other is provided with a positioning hole 111 that is positioned and engaged with the positioning member 216.

[0140] For example, the first part 21 of the switch is provided with a positioning member 216, and the circuit board body 11 is provided with a positioning hole 111 that mates with the positioning member 216; or, the circuit board body 11 is provided with a positioning member 216, and the first part 21 of the switch is provided with a positioning hole 111 that mates with the positioning member 216. The former can be selected to simplify the process.

[0141] It should be noted that when the board-side connector 12 and the switch-side connector 211 are mated together, the positioning member 216 and the positioning hole 111 are positioned together in a plane perpendicular to the mating direction; when the board-side connector 12 and the switch-side connector 211 are inserted together, the positioning member 216 and the positioning hole 111 are positioned together in a plane perpendicular to the insertion direction.

[0142] The number and shape of the positioning elements 216 are selected according to the actual situation. The positioning holes 111 are adapted to the positioning elements 216. This application embodiment does not limit this.

[0143] In this embodiment of the application, the first part 21 of the switch has a switch body (not shown in the figure), and the switch-side connector 211 is electrically connected to the switch body. For example, the switch-side connector 211 is electrically connected to the positive and negative terminals of the switch body. Figure 5 As shown, the switch-side connector 211 can be electrically connected to the switch body via a wire 215. One end of the wire 215 is provided with a conductive tube 214, and the wire 215 is inserted into the switch-side connector 211 through the conductive tube 214 to achieve electrical connection. A portion of the wire 215 can be embedded in the first part 21 of the switch, with the portion of the wire 215 and the conductive tube 214 exposed to facilitate electrical connection between the conductive tube 214 and the switch-side connector 211.

[0144] In the above structure, during the rotation of the switching device 20, the wire 215 can release at least part of the stress generated by the rotation of the switching operation part 22a of the switching device 20, thereby reducing the impact of the rotation of the switching device 20 on the electrical connection between the switch-side connector 211 and the plate-side connector 12 and improving the reliability of the electrical connection between the switch-side connector 211 and the plate-side connector 12.

[0145] The technical features mentioned above, as well as those shown individually in the accompanying drawings, can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are those explicitly described herein.

[0146] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
