The embodiment of the application provides an air conditioner, which can comprise at least one of an indoor unit and an outdoor unit. When the air conditioner is in an operating state, the heat exchangers in the indoor unit and the outdoor unit are required to be in contact with air and exchange heat. When the air conditioner is in a refrigerating working condition, the heat exchanger in the indoor unit can cool the nearby air, and correspondingly, the heat exchanger in the outdoor unit can heat the nearby air for carrying the heat of the indoor air to the outdoor so as to achieve the effect of efficiently refrigerating the indoor environment. Correspondingly, when the air conditioner is in a heating working condition, the heat in the outdoor air can be conveyed to the indoor space, so that the effect of efficiently refrigerating the indoor environment is achieved.

As shown in fig. 1, fig. 1 is a schematic perspective view of an air conditioner 100 according to an embodiment of the present disclosure. The air conditioner 100 includes an outdoor unit 10. For example, the outdoor unit 10 may include a casing 1, and the casing 1 may include a bottom plate 11, a first side plate 12, a second side plate 13, and legs 14. The number of legs 14 may be two, three or even more and may be mounted on the same side of the base plate 11 for supporting the housing 1. Exemplarily, with the side of the leg 14 on the bottom plate 11 as the lower part and two shorter edges of the bottom plate 11 as the left and right edges, the other two edges of the corresponding bottom plate 11 may be the front and rear edges (in this case, the bottom plate 11 may be approximately in a quadrilateral structure). The lower end edge of the first side plate 12 and the lower end edge of the second side plate 13 may be connected to both left and right edges of the bottom plate 11, respectively. So that the first side plate 12 and the second side plate 13 can be installed to be opposed to and spaced apart from each other. When the connecting device is connected with the bottom plate 11, the left and right edges of the bottom plate 11 can be respectively bent upwards by 90 degrees and connected by screws, rivets or welding. In addition, the lower side edge of the first side plate 12 may be bent 90 ° to the right, and the lower side edge of the second side plate 13 may be bent 90 ° to the left and brought into contact with the left and right edges of the bottom plate 11, respectively, and then connected by means of screws, rivets, or welding.

Furthermore, in other embodiments, the housing 1 may not be provided with a plurality of legs 14 connected to the bottom plate 11. I.e. the housing 1 can be supported directly by the bottom plate 11.

With continued reference to fig. 1, the housing 1 may further include a panel assembly 15 and a top cover 16. Exemplarily, in connection with fig. 2, the panel assembly 15 may include a front panel 151 and an access panel 152, a right side edge of the front panel 151 may be connected with a left side edge of the access panel 152, and a left side edge of the front panel 151 may be connected with a front side edge of the first side panel 12, and a right side edge of the corresponding access panel 152 may be connected with a front side edge of the second side panel 13. The left and right edges of the top cover 16 can be connected to the upper edge of the first side plate 12 and the upper edge of the second side plate 13, respectively. Further, the front side edge of the top cover 16 may also be connected with the upper side edge of the front panel 151 and the upper side edge of the access panel 152, respectively. In this way, the bottom plate 11, the first side plate 12, the second side plate 13, the top cover 16 and the panel assembly 15 may enclose the accommodating cavity 17.

It should be noted that in the embodiment shown in fig. 1 and 2, the housing 1 may further include a middle partition 18. The middle partition 18 may be installed in the receiving cavity 17, a lower side edge of the middle partition 18 may be connected to the bottom plate 11, and a front side edge of the middle partition 18 may be connected to a right side edge of the front panel 151 (which is equivalent to the front side edge of the middle partition 18 may also be connected to a left side edge of the service panel 152). Wherein, the upper side edge of the middle partition 18 can be disposed near the top cover 16 or even connected with the top cover 16, and the rear side edge of the middle partition 18 can be bent to the right to extend near the second side plate 13 and can be connected with the second side plate 13. In this manner, the middle bulkhead 18, the second side panel 13, the access panel 152, the right portion of the bottom panel 11, and the right portion of the top cover 16 may enclose a press cavity 171. Accordingly, the middle partition 18, the first side plate 12, the front panel 151, a left portion of the bottom plate 11, and a left portion of the top cover 16 may enclose the fan cavity 172. That is, the accommodation chamber 17 can be divided into two parts, i.e., the blower chamber 172 on the left side and the press chamber 171 on the right side, by the provision of the intermediate partition 18. Thus, both the compressor chamber 171 and the fan chamber 172 can be considered as part of the receiving chamber 17. As such, referring to fig. 1, the outdoor unit 10 may further include a fan assembly 2 and a fan bracket 3. The fan bracket 3 may be located in the fan cavity 172, and the lower end of the fan bracket 3 may be connected to the bottom plate 11, and the upper end of the corresponding fan bracket 3 may be connected to at least one of the front panel 151 and the first side plate 12, so that the fan bracket 3 may be stably installed in the fan cavity 172. In this regard, the fan assembly 2 may be mounted to the fan support 3 by screws or rivets so that the fan assembly 2 may be located within the fan cavity 172. In this way, the fan assembly 2 may be driven to rotate by electrical power such that ambient air may flow rapidly through the fan cavity 172.

The air conditioner 100 may be provided with one or more fan assemblies 2 in the outdoor unit 10 according to different cooling or heating powers. For example, as shown in fig. 1, if the power of the air conditioner 100 is large, two fan assemblies 2 may be installed in the outdoor unit 10, and the two fan assemblies 2 may be installed on the fan bracket 3 at intervals in the vertical direction. If the power of the air conditioner 100 is low, as shown in fig. 3, one fan assembly 2 may be installed in the outdoor unit 10. In addition, in other embodiments, the fan assembly 2 may also be directly mounted at a corresponding position of the housing 1, that is, the fan bracket 3 does not need to be additionally arranged, and the structure is simple.

In some embodiments, as shown in fig. 2, at least one first ventilation opening 153 may be formed in the front panel 151, and each first ventilation opening 153 may be disposed corresponding to one fan assembly 2. The rear side edge of the first side panel 12 is spaced from and forms a notch with the rear side edge of the second side panel 13 (or the rear side edge of the middle partition panel 18). Referring to fig. 3, the outdoor unit 10 may further include a heat exchanger assembly 4, and the heat exchanger assembly 4 may be installed at the notch. So, under the drive of fan subassembly 2, the outside air can be flowed in by first vent 153 to can flow through heat exchanger unit 4 after by above-mentioned breach outflow, be favorable to improving the heat exchange efficiency between refrigerant and the outside air in heat exchanger unit 4.

It should be noted that, as shown in fig. 2, a plurality of second ventilation openings 121 may be formed in the first side plate. In this way, the heat exchanger assembly 4 shown in fig. 3 can be also arranged in the fan cavity 172 near the second ventilation opening 121, which is beneficial to increasing the heat exchange area of the heat exchanger assembly 4. Further, as shown in fig. 3, the panel assembly 15 may include only the front panel 151. At this time, left and right sides of the front panel 151 may be used to connect with the first side panel 12 and the second side panel 13, respectively. When the first side plate 12 and the front panel 151 are connected, the front edge of the first side plate 12 and the left edge of the front panel 151 may be spaced apart from each other. In this way, after the heat exchanger assembly 4 is fixedly installed, the left side edge of the heat exchanger assembly 4 may be bent forward and extended close to the left side edge of the front panel 151, i.e., the left side edge of the front panel 151 is connected with the left side edge of the heat exchanger assembly 4. At this time, part of the air may directly flow out from the gap between the first side plate 12 and the front panel 151.

In the outdoor unit 10, it is necessary to control the flow speed and the flow direction of the refrigerant by controlling the opening degree of the throttle valve and the opening/closing direction of the four-way valve. The outdoor unit 10 may further include a compressor (not shown), and the compressor may be installed in the compressor chamber 171. That is, electrical components such as the compressor, the throttle valve, the four-way valve, the fan assembly 2 and the like are required to be driven and controlled through a circuit. Based on this, as shown in fig. 4, the air conditioner 100 may further include a circuit board 20, and the electric components such as the compressor, the throttle valve, the four-way valve, the fan assembly 2, and the like in the outdoor unit 10 may be driven and controlled through the circuit board 20. In some embodiments, a communication module such as a coupling board may also be disposed on the circuit board 20 for connecting with a control element in the indoor unit in a wireless or wired manner, so as to control an electrical element in the outdoor unit 10 through the circuit board 20.

Because the circuit board 20 has high requirements for water and dust resistance of the working environment, and an anti-interference device needs to be arranged for the communication module in the circuit board 20. Therefore, referring to fig. 4, the air conditioner 100 may further include a rail mounting box 30. The rail mounting box 30 may include a box body 31 and a cover plate 32. The case 31 has a mounting cavity 33 and a one-side mounting opening (not shown in the drawings) communicating with the mounting cavity 33. In this way, the cover plate 32 can be installed at the installation opening and connected with the side wall of the box body 31 at the edge of the installation opening for sealing the installation cavity 33. Thus, the circuit board 20 can be mounted in the mounting cavity 33, e.g., the circuit board 20 can be mounted adjacent to any sidewall of the mounting cavity 33. Alternatively, the circuit board 20 may be connected to the side of the cover plate 32 facing the box 31, and the circuit board 20 may be just enclosed in the accommodating chamber 33 after the mounting chamber 33 is sealed by the cover plate 32.

It should be noted that, strong and/or weak current ports may be disposed on circuit board 20, and box 31 may be respectively disposed with through holes communicating with mounting cavity 33 corresponding to the ports, so as to facilitate connection between circuit board 20 mounted in mounting cavity 33 and the outside. The strong current and/or weak current ports can be connected through the male and female ends of the plug terminals, and are convenient to install and disassemble.

In the air conditioner 100, the rail mounting box 30, to which the circuit board 20 is mounted, may be installed in the outdoor unit 10. However, the rail attachment box 30 may be attached to an indoor unit, and in this case, a control circuit board of the indoor unit may be attached to the interior of the attachment chamber 33. Still alternatively, the guide rail mounting box 30 provided in the embodiment of the present application may also be used for protecting and mounting a printed circuit board or other electronic components in other household electrical appliances, such as a washing machine, a dryer, a refrigerator, an air-source water heater, and the like. In the embodiment of the present application, the rail mounting box 30 mounted with the circuit board 20 is mounted in the accommodating chamber 17 of the outdoor unit 10 as an example.

In some embodiments, to facilitate control of a plurality of electrical components disposed proximate to the compressor assembly, such as the compressor, throttle valve, four-way valve, fan assembly 2, etc., via circuit board 20. The rail mounting box 30, to which the circuit board 20 is mounted, may be installed in the press chamber 171, and may be connected to a sidewall of the press chamber 171. Such as by screws or rivets, to the second side panel 13, the midplate 18, or a portion of the top cover 16. However, the guide rail mounting box 30 is connected to the side wall of the press chamber 171 by screws, and the mounting and dismounting operations are complicated.

Based on this, as shown in fig. 5, the guide rail mounting box 30 provided in the embodiment of the present application may further include a first snap-in piece 34 and a second snap-in piece 35. The first engaging member 34 and the second engaging member 35 can be installed on a side of the cover plate 32 far away from the installation cavity 33 (as shown in fig. 5), a direction in which the first engaging member 34 points to the second engaging member 35 is a first straight direction (i.e., an X direction), a direction perpendicular to the X direction and parallel to the cover plate 32 is defined as a second straight direction (i.e., a Y direction), and a direction perpendicular to the cover plate 32 is defined as a third straight direction (i.e., a Z direction). For example, the second snap-in member 35 may include a positioning block 351 and a snap-in block 352, the positioning block 351 may be distributed near one side edge of the cover plate 32 along the X direction and connected with the cover plate 32, and the corresponding first snap-in member 34 may be located at the other side edge of the cover plate 32 along the X direction. The clamping block 352 can be connected to one side of the positioning block 351 close to the first clamping member 34 along the X direction, and the clamping block 352 can be arranged at an interval with the cover plate 32 along the Z direction, i.e. the clamping block 352 has a gap with the cover plate 32 along the Z direction. The number of the clamping blocks 352 may be one, two, three or more. If there are a plurality of clamping blocks 352, the clamping blocks 352 may be distributed at intervals along the Y direction. If the number of the locking blocks 352 is one, one locking block 352 may be connected to the positioning block along the Y direction

With continued reference to fig. 5, the first latch 34 may include a first stopper 341 and a first latching piece 342. For example, the number of the first limiting members 341 may be two, and each of the first limiting members 341 may include one first connecting plate 3411 and one first limiting plate 3412. Along the X direction, the two first limiting members 341 may be located on the other side edge of the cover plate away from the second clamping member 35. Here, two first connecting plates 3411 may be spaced apart in the Y direction and connected to the cover plate 32, respectively. The two first stopper plates 3412 may be positioned between the two first connection plates 3411 in the Y direction, each of the first stopper plates 3412 may be connected to a neighboring one of the first connection plates 3411, and each of the first stopper plates 3412 may be positioned at an end of the connected first connection plate 3411 remote from the cover plate 32 in the Z direction. Thus, referring to fig. 6, in the Z direction, a first plug cavity 343 may be formed between the two first stopper plates 3412 and the cover plate 32. The first plugging cavity 343 has two opposite plugging openings along the X direction, which are respectively communicated with the first plugging cavity 343, that is, the two plugging openings are spaced apart along the X direction.

With reference to the above embodiment, as shown in fig. 7, the first plug-in piece 342 can be inserted into the plug-in opening of the first plug-in cavity 343 (shown in fig. 6) away from the first positioning block 351 along the X direction, and one end of the first plug-in piece 342 close to the first positioning block 351 can pass through the first plug-in cavity 343. In this manner, one end of the first card member 342 close to the first positioning block 351 may be disposed apart from (i.e., with a gap from) the cover plate 32 in the Z direction. The air conditioner 100 provided by the embodiment of the present application may further include a guide rail 40. For example, the guide rail 40 may be installed in the installation cavity 17 of the outdoor unit 10 (shown in fig. 1). The guide rail 40 is installed to be connected to the casing 1 of the outdoor unit 10. In this way, referring to fig. 7, the guide rail 40 can be placed between the positioning block 351 and the first stopper plate 3412, and the first plug-in connector 342 can be brought close to the positioning block 351 in the X direction and brought into contact with the guide rail 40. Thus, one edge of the guide rail 40 along the X direction can be clamped between the clamping block 352 and the cover plate 32 along the Z direction, and the other edge of the guide rail 40 along the X direction can be clamped between the first clamping piece 342 and the cover plate 32 along the Z direction. At this time, the first plug-in fastener 342 can be installed in the first plug-in cavity 343 in a snap-fit manner, so as to prevent the first plug-in fastener 342 from moving in the direction away from the positioning block 351 along the X direction. In this way, the positioning block 351 and the first insertion/ejection piece 342 together with at least one of the positioning blocks 352 can limit the degree of freedom of the guide rail 40 in the X direction, and the positioning block 352, the first insertion/ejection piece 342, and the cover plate 32 can limit the degree of freedom of the guide rail 40 in the Z direction.

Since the guide rail 40 can be installed in connection with the casing 1 of the outdoor unit 10. Therefore, the guide rail mounting box 30 can be clamped and mounted with the guide rail 40 by the limiting function of the positioning block 351, the clamping block 352 and the first inserting and clamping piece 342 in the second clamping piece 35. So that the rail mounting boxes 30 can be coupled and mounted near the side walls (e.g., the first side plate 12, the second side plate 13, the middle partition plate 18, the top cover 16, etc.) of the casing 1 in the outdoor unit 10, so that the rail mounting boxes 30 can be stably mounted in the mounting cavity 17 of the outdoor unit 10. The rail mounting box 30 is mounted in the above manner by merely inserting the first card member 342 to clamp the rail 40 during mounting. If the rail mounting box 30 needs to be detached, the first plug-in fastener 342 is partially pulled out in the direction away from the positioning block 351 along the X direction, so that the rail 40 and the rail mounting box 30 can be detached. Simple structure, simple operation is dismantled in the installation.

It should be noted that, in the embodiment of the present application, if the housing 1 only includes the accommodating cavity 17, the guide rail 40 and the rail mounting box 30 may be mounted near any side wall of the accommodating cavity 17, for example, the rail mounting box 30 and the guide rail 40 may be mounted near the compressor assembly. If the casing 1 has the blower chamber 172 and the compressor chamber 171, the rail attachment box 30 and the rail 40 may be attached to the inside of the compressor chamber 171 or to the inside of the blower chamber 172, and this is not limitative.

Further, as for the guide rail 40, the guide rail 40 may be a C45 type guide rail, that is, a width dimension of both edges of the guide rail 40 in the X direction is approximately 35mm. Alternatively, the guide rail 40 may be another standard type guide rail, for example, the width dimension of the two edges of the guide rail 40 along the X direction may be adjusted between 20mm and 70mm, which is not limited. The guide rail 40 may be two independent structures with respect to the outdoor unit 10, such as a screw, a rivet, a snap connection, or a welding connection between the guide rail 40 and the casing 1. Alternatively, the structure similar to the guide rail 40 may be directly formed on one of the plate materials of the housing 1 by stamping or other main methods, that is, the guide rail 40 and the housing 1 may be integrally formed. May be used to snap-fit the rail mounting box 30, and is not limited in this application.

In some embodiments, as shown in fig. 6, two first limiting plates 3412 located between the two first connecting plates 3411 may be spaced apart in the Y direction. Thus, the raw material consumption of the guide rail mounting box 30 is favorably reduced. Alternatively, referring to fig. 8, two first connection plates 3411 may be connected to each other through one first stopper plate 3412, or two first stopper plates 3412 positioned between the two first connection plates 3411 may be integrally joined to each other while being adjacent to each other. Thus, the structural strength of the first position-limiting member 341 can be improved. In the above embodiment, since the first inserting cavity 343 is located between the first position-limiting plate 3412 and the cover plate 32 along the Z direction, the first position-limiting member 341 can have the minimum thickness along the Z direction, which is beneficial to further reducing the usage amount of manufacturing materials.

In other embodiments, the first position-limiting member 341 may also be a block structure, and both the first position-limiting member 341 and the second snap-in member 35 may be mounted on a side of the cover plate 32 away from the mounting cavity 33. The first limiting member 341 may be connected to the cover plate 32, and the first limiting member 341 may have a through hole structure along the X direction to form a first inserting cavity 343 with two through ends. That is, in this embodiment, the sidewalls of the first plugging cavity 343, which do not include the cover plate 32, are part of the first position-limiting member 341.

It should be noted that, in the above embodiment, the first snap-in piece 34 and the second snap-in piece 35 are installed on the same side of the cover plate 32 far from the installation cavity 33. In addition, the first clip 34 and the second clip 35 may be mounted on the case 31. If the box 31 may include a bottom plate disposed opposite to the cover plate 32, the box 31 may further include at least three side plates connected between the bottom plate and the cover plate 32. In this way, the first clamping member 34 and the second clamping member 35 can also be mounted on the bottom plate or one of the side plates, and are located on a side of the bottom plate or one of the side plates away from the mounting cavity 33.

In some embodiments, the first plug-in connector 342 inserted into the first plug-in cavity 343 needs to be clamped and limited to prevent the first plug-in connector 342 from moving in the direction away from the positioning block 351 along the X direction when in the first clamping state.

Based on this, as shown in fig. 9, fig. 9 is a sectional view of the first clip piece 342 shown in fig. 7 in the first clipping state. Accordingly, as shown in fig. 10, fig. 10 is a partially enlarged view of a in fig. 9. Illustratively, the first clip 34 may further include a first hook 344 and a first limit protrusion 345. The first hook 344 may be located on a side of the first plug-in fastener 342 close to the cover plate 32, and the first hook 344 may be connected with the first plug-in fastener 342. Accordingly, the first limit protrusion 345 may be connected to a side of the cover plate 32 away from the installation cavity 33 and disposed near the first plugging cavity 343. That is, the first limiting protrusion 345 may be located outside the first plugging chamber 343 and disposed near both ends of the first plugging chamber 343 in the Z direction. Alternatively, the first limiting protrusion 345 may be directly located in the first plugging cavity 343.

Thus, when the first plug fastener 342 is in the first fastening state, the first hook 344 may be located on one side of the first limiting protrusion 345 close to the positioning block 351 along the X direction, and the first hook 344 contacts or even attaches to the first limiting protrusion 345. Since the first plug-in connector 342 located in the first plug-in cavity 343 is limited by the first position-limiting plate 3412 and the cover plate 32 in the Z-direction, the first plug-in connector 342 is prevented from moving in the X-direction away from the positioning block 351 by the first position-limiting protrusion 345, that is, the first plug-in connector 342 is prevented from moving away from the positioning block 351 in the first engaging state. At this time, the guide rail 40 may be installed between the positioning block 351 and the first limiting member 341, and the guide rail 40 may be installed by being clamped by the first inserting-clamping piece 342 and the clamping block 352 in the first clamping state, so that the guide rail 40 may be separated from the cover plate 32 along the Z direction, and the clamping installation between the guide rail installation box 30 and the guide rail 40 may be realized.

With continued reference to fig. 10, the first clip 34 may further include a second clip 346 and a second limiting protrusion 347. For example, in the X direction, the second limiting protrusion 347 may be located on a side of the first limiting protrusion 345 away from the positioning block 351 (as shown in fig. 9), and the second limiting protrusion 347 may be connected to the same side of the cover plate 32 as the first limiting protrusion 345. Accordingly, in the X direction, the second hook 346 may be located on a side of the first hook 344 away from the positioning block 351, and the second hook 346 may be connected to a same side of the first plug-in connector 342 as the first hook 344. Thus, when the first plug-in fastener 342 is in the first engaging state, the second hook 346 may be located on a side of the second limiting protrusion 347 away from the positioning block 351 along the X direction. Therefore, even if the first plug-in fastener 342 in the first clamping state is not used for installing the guide rail 40, the second limiting protrusion 347 limits and blocks the second hook 346 in the X direction, so that the situation that the first plug-in fastener 342 continues to approach the positioning block 351 in the X direction and finally breaks away from the first plug-in cavity 343 to cause the first plug-in fastener 342 to fall off can be avoided.

It should be noted that, the first card member 342 is easy to be mounted. As shown in fig. 10, the first and second spacing protrusions 345 and 347 may be provided to be spaced apart in the X direction. The height of the first stopper protrusion 345 may be defined as the distance between the first stopper protrusion 345 and the cover plate 32 in the Z direction. Accordingly, the height of the second limiting protrusion 347 may be a distance between the second limiting protrusion 347 and the cover plate 32 in the Z direction. The height of the first position-limiting protrusion 345 may be gradually reduced along the X direction in a direction away from the positioning block 351 (as shown in fig. 9). Correspondingly, the height of the second limiting protrusion 347 can also be gradually reduced along the X direction in the direction away from the positioning block 351.

In this way, in the process that the first plug-in hook 342 moves in the first plug-in cavity 343 toward the positioning block 351 along the X direction, the first hook 344 may sequentially contact the inclined surfaces of the second limiting protrusion 347 and the first limiting protrusion 345. Through the guiding of the inclined surface, the blocking of the first hook 344 during the moving process can be reduced, so that the first plug-in card 342 is inserted into the first plug-in cavity 343 and moves to the first clamping state.

Based on the above embodiment, with continued reference to fig. 10, it can be defined that the height of the first hook 344 is the distance between the first hook 344 and the first plug-in piece 342 along the Z direction. As such, the height of the first hook 344 may gradually increase along the X direction in a direction away from the positioning block 351 (as shown in fig. 9). Thus, when the first plug-in connector 342 is inserted into the first plug-in cavity 343 and moves to the first clamping state, the inclined surface of the first hook 344 is also beneficial to reducing the resistance between the first hook 344 and the first limiting protrusion 345 and the second limiting protrusion 347, so that the clamping installation is more convenient.

In addition, as shown in fig. 11, in some other embodiments, the first plug element 342 near the first hook 344 may be provided with an elastic through hole 348, the elastic through hole 348 may be a bar-shaped hole, and the elastic through hole 348 is partially disposed around the first hook 344. For example, the elastic through hole 348 may be opened on the first plug-in component 342 along the Z direction, and along the X direction, the elastic through hole 348 may be located on one side of the first hook 344 away from the second hook 346, and along the Y direction, the elastic through hole 348 may be located on two opposite sides of the first hook 344. That is, the elastic through-hole 348 may be disposed to half-surround the first hook 344. The degree of freedom of the first hook connected with the first plug-in fastener 342 in the Z direction is improved, and the first plug-in fastener 342 can be inserted, clamped and detached conveniently.

In other embodiments, the elastic through hole 348 may also be located on one side of the first hook 344 close to the second hook 346 along the X direction, and the elastic through hole 348 may also be located on two opposite sides of the first hook 344 along the Y direction, and may also semi-surround the first hook 344 to achieve the above-mentioned effect. This is not limitative.

With continued reference to fig. 11, for example, the first clamping member 34 may further include a first toggle member 3491, the first toggle member 3491 may be located on a side of the first plug-in connector 342 close to the cover 32 along the Z direction, and an end of the first plug-in connector 342 far away from the first hook 344 along the X direction may be connected to the first toggle member 3491. In this way, when the first plug-in connector 342 continues to approach the positioning block 351 along the X direction from the first clamping state (as shown in fig. 9), the first toggle member 3491 may contact with the edge of the cover plate 32 to prevent the first plug-in connector 342 from separating from the first plug-in cavity 343 towards the positioning block 351 (as shown in fig. 10).

Moreover, if the first plug-in fastener 342 needs to move from the first clamping state to the direction far away from the positioning block 351, the first toggle member 3491 can be directly toggled, so that the first plug-in fastener 342 can be far away from the positioning block 351 along the X direction, which is very convenient.

Further, as shown in fig. 11, the first clip member 342 may further have a toggle hole 3492. Illustratively, the toggle hole 3492 may be located at an end of the first bayonet piece 342 away from the first hook 344 in the X direction. In this way, it is very convenient to insert the poke rod into the poking hole 3492 to poke the first plug fastener 342 to approach the positioning block 351 along the X direction (as shown in fig. 9) or to be away from the positioning block 351. The toggle hole 3492 may be a through hole or a blind hole, and only needs to be adapted to the toggle rod to move the first plug-in fastener 342 in the X direction. The toggle hole 3492 can be formed along the Z direction and can be a circular hole, a triangular hole, a rectangular hole or other conventional shapes. The toggle holes 3492 may also be flat bar holes for fitting a straight screwdriver. Still alternatively, the toggle hole 3492 may also be a cross-shaped hole structure for adapting to a cross-shaped screwdriver. This is not limitative.

In addition, as shown in fig. 11, the first clamping member 34 may further include two supporting ribs 3493, the two supporting ribs 3493 may be located on the same side of the first clamping member 342 as the first hook 344, and the two supporting ribs 3493 are respectively connected to two edges of the first clamping member 342 along the Y direction. In this way, the first plug-in member 342 inserted into the first insertion cavity 343 (shown in fig. 10) and the cover plate 32 can be supported by the first hook 344 or the two support ribs 3493, so that a gap is formed between the first plug-in member 342 and the cover plate 32, so as to facilitate the clamping of the edge of the mounting rail 40 (shown in fig. 7). Meanwhile, the two reinforcing ribs connected to the edge of the first inserting-clamping piece 342 can also improve the structural strength of the first inserting-clamping piece 342, which is beneficial to increasing the service life of the first clamping piece 34.

It should be noted that a chamfer or a rounded corner may be provided at one end of the first latching member 342 close to the positioning block 351 toward the cover plate 32. Accordingly, the end of the clamping block 352 away from the positioning block 351 may also be chamfered or rounded toward the cover plate 32. Thus, the distance between the first plug piece 342 and the end of the plug-in block 352 and the cover plate 32 can be increased, and one side can accommodate the installation rail 40.

In other embodiments, a limiting protrusion may be installed on a side wall of the first connecting plate 3411 and/or the first limiting plate 3412 close to the first plug-in cavity 343, and a hook is installed on the first plug-in latch 342 corresponding to the limiting protrusion, so that the first plug-in latch 342 and the first plug-in cavity 343 may be inserted and clamped to achieve the effect of clamping and installing the guide rail 40.

In addition, the second clip member 35 may be a mirror image of the first clip member 34. As shown in fig. 12, the second locking member 35 may also include a second limiting member 353 and a second locking member 354. For example, the number of the second limiting members 353 may be two, and each of the second limiting members 353 may include one second connecting plate 3531 and one second limiting plate 3532. Two second connection plates 3531 may be spaced apart in the Y direction and connected to the cap plate 32. The two second connecting plates 3531 are connected to the same side of the cover plate 32 as the two first connecting plates 3411, and are respectively distributed near two edges of the cover plate 32 in the X direction. Between the two second connecting plates 3531, the two second limiting plates 3532 may be respectively connected to ends of the two second connecting plates 3531 far away from the cover plate, so that a second inserting cavity 355 may be formed between the two second limiting plates 3532 and the cover plate. Thus, the second plug-in clip 354 can be inserted in the X direction and snap-fitted through the second plug-in cavity 355. When the second clip piece 354 is in the second clipping state and the first clip piece 342 is in the first clipping state, the rail 40 can be installed by clipping between the ends of the second clip piece 354 and the first clip piece 342 that are close to each other along the X direction (as shown in fig. 7).

It should be noted that, in the embodiment of the present application, in the case that the second clamping member 35 includes the second limiting member 353 and the second insertion member 354, the second clamping member 35 and the first clamping member 34 may be approximately in a mirror-image symmetric structure. Therefore, the specific structure of the second engaging member 35 can be set by referring to the structure of the first engaging member 34 in the above embodiment, which is not described herein again.

In some embodiments, the fixed circuit board 20 is mounted in the rail mounting box 30. As shown in fig. 13, taking the approximately rectangular structure of the circuit board 20 as an example, the circuit through holes 21 may be opened at any two opposite corners of the circuit board 20. The box 31 further includes a plurality of pillars 311 and a plurality of pillar ribs 312 installed in the installation cavity 33, and each pillar 311 and each pillar rib 312 may extend along the Z direction, respectively. Each post 311 may be disposed near a corner of the mounting cavity 33, and each post 311 may be connected to the box 31 by a post rib 312. At least one supporting rib 312 connected with the inner side wall of the box 31 may be disposed between two adjacent supporting columns 311.

As shown in fig. 14, when the circuit board 20 is mounted near the mounting opening of the mounting cavity 33, each of the support posts 311 is aligned and inserted into one of the circuit through holes 21, and the circuit board 20 may contact the plurality of support ribs 312 and be supported by the plurality of support ribs 312 at the mounting opening. Correspondingly, at least two diagonally opposite support posts 311 are respectively provided with a threaded hole 313. In this way, when the cover plate 32 is mounted near the mounting opening, the circuit board 20 can be mounted between the cover plate 32 and the plurality of support ribs 312 in a pressing manner, and the cover plate 32 can be provided with cover plate through holes 321 corresponding to each screw hole 313.

Thus, the circuit board 20 can be press-fitted between the cover plate 32 and the support ribs 312 by screws passing through the circuit through holes 21 while connecting the cover plate 32 and the support posts 311 to connect the cover plate 32 and the case 31. In the above structure, the screw passes through the circuit through hole 21 arranged near the corner of the circuit board 20, so that the screw can be prevented from approaching or even contacting the circuit trace or electronic element in the middle area of the circuit board 20, the zero contact design of the circuit board 20 and the screw is facilitated, and the stability of the circuit board 20 is improved.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
