Referring to fig. 1 to 3, fig. 1 is a first structural schematic diagram of an embodiment of a frequency converter mounting assembly according to the present utility model; FIG. 2 is a second schematic diagram of an embodiment of a transducer mounting assembly of the present utility model; fig. 3 is a schematic partial structure of an embodiment of the frequency converter mounting assembly of the present utility model. The present utility model proposes a frequency converter mounting assembly 10. The frequency converter mounting assembly 10 comprises a bracket 1 and a housing 2. The holder 1 is intended to be connected to a device to be assembled (not shown). The equipment to be installed may be a compressor or the like, and is not limited herein. The housing 2 is detachably connected to the side of the bracket 1 facing away from the device to be assembled. The housing 2 is concavely provided with a receiving groove 21 toward one side of the bracket 1. The bracket 1 is inserted into the accommodating groove 21 to form a connecting cavity 3. Through the above-mentioned setting, when there is rivers in casing 2 outside, because support 1 inserts and locates accommodation groove 21 and form connecting chamber 3, connecting chamber 3 is surrounded by support 1 and casing 2 promptly, and rivers can be blocked by casing 2 and support 1, are difficult for getting into connecting chamber 3 inside, have realized the preliminary waterproof of converter installation component 10.

Wherein the side of the receiving groove 21 facing the bracket 1 is provided with a first terminal 22 and a first guide 23. The first terminal 22 may be used for electrical conduction. The receiving groove 21 has first and third side walls 21a and 21c disposed opposite to each other, and second and fourth side walls 21b and 21d disposed opposite to each other. The first and third side walls 21a and 21c are located between the second and fourth side walls 21b and 21d. The first guide 23 is provided between the first terminal 22 and the first side wall 21a. The first guide 23 is disposed to extend obliquely toward the second side wall 21b. The projection of the first terminal 22 on the third side wall 21c is located within the projection of the first guide 23 on the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21 c.

By further providing the first guide 23 inclined toward the second side wall 21b such that the projection of the first guide 23 on the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21c is larger than the projection of the first terminal 22 on the third side wall 21c, water permeated into the connection chamber 3 flows along the first guide 23 and is guided away from the first terminal 22. Thus, the first terminal 22 of the frequency converter mounting assembly 10 is not in contact with water, improving the waterproof performance of the frequency converter mounting assembly 10 compared to the prior art.

The shape of the first guide 23 may be set according to practical situations, and it is only necessary to achieve the diversion of water away from the first terminal 22, which is not limited herein. As in the present embodiment, the first guide 23 is provided obliquely extending from the middle toward the second side wall 21b and the fourth side wall 21d, respectively, in the direction from the first side wall 21a toward the third side wall 21 c. As another embodiment, the first guide 23 is provided continuously obliquely extending from left to right in a direction from the first side wall 21a toward the third side wall 21 c. As in the other embodiments, the first guide 23 is provided continuously obliquely extending from right to left in the direction from the first side wall 21a toward the third side wall 21 c.

In the present embodiment, the direction along the direction from the first side wall 21a toward the third side wall 21c is the downward direction.

The connection between the housing 2 and the bracket 1 may be, for example, a snap connection, a bolt connection, or a pin connection, and is not limited thereto. As in one embodiment, the housing 2 is provided with a first mounting portion 29. The bracket 1 is provided with a second mounting portion 11. The first mounting portion 29 is attached to the second mounting portion 11. The first mounting portion 29 is provided with a first mounting hole 291 penetrating toward one side of the second mounting portion 11. The second mounting portion 11 has a second mounting hole 111 formed therethrough on a side facing the first mounting portion 29. A fixing member (not shown) is commonly inserted into the first mounting hole 291 and the second mounting hole 111. The fixing member may be a screw or the like, and is not limited herein.

With continued reference to fig. 1-3, in one embodiment, the first guide 23 includes a first guide 231 and a second guide 232. The distance between the first guide 231 and the first sidewall 21a gradually increases in a direction away from the second guide 232. The distance between the second guide 232 and the first sidewall 21a gradually increases in a direction away from the first guide 231. By arranging the first guide part 231 and the second guide part 232, the first guide piece 23 can split and guide water penetrating into the connecting cavity 3 to two sides away from the first terminal 22, so that the flow guiding capacity of the first guide piece 23 is improved, the first terminal 22 cannot be contacted with water, and the waterproof performance of the frequency converter mounting assembly 10 is enhanced.

The distribution forms of the first guide portion 231 and the second guide portion 232 may be set according to actual situations, and the water may be guided to both sides, which is not limited herein. As in the present embodiment, one end of the first guide 231 near the second guide 232 is connected to one end of the second guide 232 near the first guide 231. As another embodiment, the first guide 231 is provided separately from the second guide 232. One end of the first guide portion 231 adjacent to the second guide portion 232 is disposed between one end of the second guide portion 232 adjacent to the first guide portion 231 and the first side wall 21a. The projection of the end of the first guide portion 231 near the second guide portion 232 on the third side wall 21c at least partially coincides with the projection of the end of the second guide portion 232 near the first guide portion 231 on the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21 c. As yet other embodiments, the first guide 231 is provided separately from the second guide 232. One end of the second guide portion 232 adjacent to the first guide portion 231 is disposed between one end of the first guide portion 231 adjacent to the second guide portion 232 and the first sidewall 21a. The projection of the end of the first guide portion 231 near the second guide portion 232 on the third side wall 21c at least partially coincides with the projection of the end of the second guide portion 232 near the first guide portion 231 on the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21 c.

With continued reference to fig. 1 to 3, in an embodiment, the second side wall 21b of the accommodating groove 21 is provided with a first drain hole 211. One end of the second guide portion 232 remote from the first guide portion 231 extends to the first liquid discharge port 211. By arranging the first liquid discharge port 211 and extending the second guide portion 232 to the first liquid discharge port 211, the guided water can be discharged from the first liquid discharge port 211 to the connecting cavity 3, so that the water can be prevented from gathering in the connecting cavity 3, and the waterproof performance of the frequency converter mounting assembly 10 is further improved.

With continued reference to fig. 1 to 3, the side of the accommodating groove 21 facing the bracket 1 is provided with a second guide member 24. The second guide 24 is disposed between the first terminal 22 and the third side wall 21 c. The second guide 24 surrounds at least a portion of the area where the first terminal 22 is located. The second guide 24 is provided with a second drain port 241 at one end near the third side wall 21 c. By providing the second guide 24 between the first terminal 22 and the third side wall 21c around at least part of the area where the first terminal 22 is located, water entering the connection cavity 3 from below the frequency converter mounting assembly 10 can be blocked from contacting the first terminal 22 with water. Meanwhile, the second liquid drain port 241 is formed at one end of the second guide member 24, which is close to the third side wall 21c of the accommodating groove 21, so that even if water accidentally enters into one side of the second guide member 24, which faces the first terminal 22, the water is guided by the second guide member 24 and is discharged from the second liquid drain port 241, and the waterproof performance of the frequency converter mounting assembly 10 is improved.

The shape of the second guide 24 may be set according to the actual situation, and it is only necessary to block the water entering the connection chamber 3 from the third sidewall 21c of the container 21 and to guide the water to the second drain 241, which is not limited herein. As in the present embodiment, the second guide 24 is arranged in a semicircular shape around the first terminal 22. The projection of the second guide 24 onto the third side wall 21c is inside the projection of the first guide 23 onto the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21 c. As another example, the second guide 24 is disposed in a full circle around the first terminal 22. The projection of the second guide 24 onto the third side wall 21c is inside the projection of the first guide 23 onto the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21 c. By providing the second guide 24 as a semicircle or full circle, the water flow can be efficiently guided along the inner side wall. Meanwhile, since the projection of the second guide 24 on the third side wall 21c is inside the projection of the first guide 23 on the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21c, the water guided by the first guide 23 does not flow onto the second guide 24, avoiding accumulation of water on the second guide 24.

With continued reference to fig. 1 to 3, in one embodiment, the side of the accommodating groove 21 facing the bracket 1 is provided with a third guide member 25. The third guide 25 is provided between the first guide 23 and the first side wall 21a. The third guide 25 is provided to extend obliquely toward the second side wall 21b and/or the fourth side wall 21d. The projection of the third guide 25 on the third side wall 21c is located within the projection of the first guide 23 on the third side wall 21c in the direction from the first side wall 21a toward the third side wall 21 c. By providing the third guide member 25 which is inclined and is located inside the projection of the first guide member 23 on the third side wall 21c along the projection of the first side wall 21a onto the third side wall 21c, the water penetrating into the connecting cavity 3 from the first side wall 21a is partially contacted with the third guide member 25 and guided, and then flows onto the first guide member 23, so that the water flow is guided more accurately, the phenomenon that the water splashing is generated due to the impact caused by the larger potential energy and the longer distance when the water flow falls onto the first guide member 23 from the first side wall 21a is avoided, the contact between the first terminal 22 and the water is further avoided, and the waterproof performance of the frequency converter mounting assembly 10 is improved.

The third guide 25 may be shaped to guide water, and is not limited thereto. As in the present embodiment, the third guide 25 includes a first sub-guide 251, a second sub-guide 252, and a third sub-guide 253 that are disposed separately in this order from left to right. The second sub-guide 252 is provided to extend obliquely from the middle to the left and right sides in a direction from the first side wall 21a toward the third side wall 21 c. The first sub-guide 251 is disposed below the second sub-guide 252 and is continuously inclined from right to left along the direction from the first side wall 21a toward the third side wall 21 c. The third sub-guide 253 is disposed below the second sub-guide 252 and is disposed continuously obliquely from left to right in a direction from the first side wall 21a toward the third side wall 21 c. As an alternative embodiment, the third guide 25 is provided to extend obliquely from the middle to both the left and right sides of the second and fourth side walls 21b and 21d in the direction from the first side wall 21a toward the third side wall 21 c. As another alternative embodiment, third guide 25 is provided to extend obliquely continuously from left to right toward second side wall 21b in a direction from first side wall 21a toward third side wall 21 c. As yet another alternative, the third guide 25 is provided to extend continuously obliquely from right to left toward the fourth side wall 21d in a direction from the first side wall 21a toward the third side wall 21 c.

In addition, the extension length of the third guide 25 may be set according to practical situations, and is not limited herein. As in the present embodiment, the projection of the end of the third guide 25 near the second side wall 21b of the accommodating groove 21 on the third side wall 21c along the direction from the first side wall 21a toward the third side wall 21c at least partially coincides with the projection of the first liquid discharge port 211 on the third side wall 21 c. Through the arrangement, at least part of the water guided by the third guiding part can be guided to the first liquid outlet 211 and is directly discharged out of the connecting cavity 3 from the first liquid outlet 211, so that the water flow flowing from the third guiding part 25 to the first guiding part 23 is reduced, namely, the multi-layer guiding and discharging of the water flow are realized, the first terminal 22 can not be contacted with the water, and the waterproof performance of the frequency converter mounting assembly 10 is improved.

When the inverter mounting assembly 10 is mounted to the equipment to be installed, water flow may occur intensively at one end of the housing 2. With continued reference to fig. 1 to 3, in one embodiment, an end of the bracket 1 near the first sidewall 21a is provided with a plugging portion 12. The plugging portion 12 is disposed at a side of the bracket 1 facing the accommodating groove 21. The insertion portion 12 is inserted into the accommodating groove 21. The accommodating groove 21 is provided with an extension 26 at the first side wall 21a and/or the fourth side wall 21d. Along the accommodating groove 21 toward the bracket 1, the extending portion 26 protrudes from the inserting portion 12.

Specifically, when the housing 2 is mounted to the bracket 1, the housing 1 is completely inserted into the accommodating groove 21 because the housing 2 is mounted to the bracket 1, specifically, the housing 1 is inserted into the accommodating groove 21. Since the plugging portion 12 is disposed at the side of the bracket 1 facing the accommodating groove 21, the plugging portion 12 is completely plugged into the accommodating groove 21. At this time, the extending portion 26 protrudes from the insertion portion 12 along the accommodating groove 21 toward the bracket 1.

Through the arrangement, when the shell 2 contacts water flow, the extending part 26 exceeds the inserting part 12 in the direction of the accommodating groove 21 towards the bracket 1, and the extending part 26 can block the water flow, so that the extending part is difficult to contact with a gap at the intersection of the inserting part 12 and the shell 2, the water flow is difficult to infiltrate into the connecting cavity 3 from the gap, and the waterproof performance of the frequency converter mounting assembly 10 is improved.

The shape of the insertion portion 12 may be set according to practical situations, and is not limited herein. In one embodiment, the plugging portion 12 extends from the fourth side wall 21d toward the second side wall 21b. The insertion portion 12 is bonded to the first side wall 21a, the second side wall 21b, and the fourth side wall 21d at the same time. In another embodiment, the plugging portion 12 extends from the fourth side wall 21d toward the second side wall 21b. The insertion portion 12 is attached to the first side wall 21a. As another specific embodiment, the plugging portion 12 extends from the fourth side wall 21d toward the second side wall 21b. The insertion portion 12 is bonded to both the first side wall 21a and the second side wall 21b.

The distribution of the extension portions 26 may be set according to practical situations, and is not limited herein. In one embodiment, the extension 26 includes a first sub-extension 261 and a second sub-extension 262. The first sub-extension 261 is disposed adjacent to the first sidewall 21a and extends rightward along the upper sidewall of the accommodating groove 21. The second sub-extension 262 is disposed near the fourth end of the accommodating groove 21 and extends downward along the left sidewall of the accommodating groove 21. As another specific embodiment, the extension 26 includes a first sub-extension 261 and a second sub-extension 262. The first sub-extension 261 is disposed adjacent to the first sidewall 21a and extends along the upper sidewall of the accommodating groove 21 with equal length. The second sub-extension 262 is disposed near the fourth end of the accommodating groove 21 and extends along the left sidewall of the accommodating groove 21 with equal length. As yet other embodiments, the extension 26 is disposed circumferentially along the sidewall of the receiving slot 21.

Referring to fig. 4, fig. 4 is an exploded view of an embodiment of a transducer mounting assembly 10 according to the present utility model. Referring to fig. 1 to 3, in an embodiment, the bracket 1 is provided with a blocking portion 13 at one end near the third side wall 21 c. The projection of the blocking portion 13 along the direction from the third side wall 21c toward the first side wall 21a is at least partially located at the first side wall 21a. Through the arrangement, the blocking part 13 and the third side wall 21c can form staggered blocking, water flow from the direction of the third side wall 21c of the accommodating groove 21 can be blocked by the blocking part 13 and the third side wall 21c and cannot enter the connecting cavity 3, so that the sealing performance of the connecting cavity 3 is enhanced, the sealing performance of the frequency converter mounting assembly 10 is further enhanced, and the water flow is prevented from contacting the first terminal 22.

The positional relationship between the blocking portion 13 and the third side wall 21c may be set according to actual circumstances, and is not limited herein. In one embodiment, a side surface of the blocking portion 13 facing the third sidewall 21c is attached to a side surface of the third sidewall 21c facing the blocking portion 13. At this time, a surface seal can be formed between the blocking portion 13 and the third side wall 21c, and the blocking effect of the blocking portion 13 and the third side wall 21c on the water flow is enhanced. In another embodiment, a side of the blocking portion 13 facing the third sidewall 21c is not attached to a side of the third sidewall 21c facing the blocking portion 13. At this time, the blocking portion 13 and the third side wall 21c are kept at a distance therebetween, so that water in the connection chamber 3 is favorably discharged from between the blocking portion 13 and the third side wall 21c, and water accumulation in the connection chamber 3 is less likely to occur.

The blocking portion 13 may be fixedly connected or integrally formed with the bracket 1. In one embodiment, the blocking portion 13 is a protruding structure integrally extending from one end of the bracket 1 near the third sidewall 21c of the accommodating groove 21 along the direction from the bracket 1 to the accommodating groove 21.
