Description

Technical Field

[0001] The invention relates to the field of sealing products, and in particular to a sealing component and an electrical cabinet. Background Art

[0002] In existing electrical cabinets, the upper and lower ends of the power module have through holes to connect with other modules. In order to prevent water or dust from entering the power module through the through holes, sealing treatment is usually required, such as arranging a sealing ring around the through hole. Specifically, when the power module is inserted into the cabinet, the sealing ring on the lower side contacts the cabinet and is squeezed and deformed by the cabinet and the power module, thereby achieving sealing. Similarly, the sealing ring on the upper side contacts the air cavity module and is squeezed and deformed by the air cavity module and the power module, thereby achieving sealing. However, if good sealing performance needs to be ensured, a certain deformation of the sealing ring is required. Therefore, the size of the power module (including the sealing ring) needs to be interference fit with the insertion position to deform the sealing ring. However, due to the interference fit, it is easy to interfere with the cabinet and the air cavity module during insertion, resulting in unsmooth installation. Conversely, if smooth installation is guaranteed, the sealing is difficult to ensure. Summary of the invention

When in the second position, the moving part is away from the insert, so that the second sealing part is separated from the moving part and the insert, so that the size of the insertion cavity can be larger than the size of the insert, which is convenient for the insert to be inserted or withdrawn from the insertion cavity, and to achieve installation or disassembly, so as to meet the sealing performance and easy disassembly at the same time.

[0023] 2. In the second solution and its preferred embodiment, the moving part is rotationally connected or slidably connected to the main body to move between the first position and the second position to achieve a position change.

[0024] 3. In scheme three and its preferred embodiment, the moving part is located above or below the insert, and is slidably connected to the main body. The moving part is supported by the main body in both the first position and the second position, so that the moving part has a support position in both positions and will not slide due to its own gravity, thereby eliminating the need to maintain the position of the moving part when installing or removing the insert, which is more convenient.

[0025] 4. In scheme 4 and its preferred embodiments, one of the main body and the moving part is provided with a guide slide hole, and the other is provided with a guide column slidably matched with the guide slide hole.

The insertion cavity is provided with a horizontal guide surface parallel to the first direction, and the insert is suitable for sitting on the horizontal guide surface and sliding along the horizontal guide surface until the two ends of the first sealing part are respectively suitable for abutting the first inclined surface and the second inclined surface. During the plug-in process, the insert is supported by the horizontal guide surface, which can be more convenient for assembly and disassembly.

[0030] 9. In scheme nine and its preferred embodiments, during the movement of the moving part toward the first position, the insert is pressed to make the insert approach the main body, and the main body and the insert are respectively pressed against the two ends of the first sealing part to further compress the first sealing part, so as to improve the sealing effect of the first sealing area.

[0050] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0051] refer to Figure 1-Figure 11 An electrical cabinet includes a sealing assembly, wherein the sealing assembly includes a body 1, a moving part 2, an insert 3, a first sealing part 4, and a second sealing part 5. In other embodiments, the sealing assembly can be used on other products.

[0052] refer to Figure 1 , Figure 2The main body 1 is a cabinet, and the main body 1 is provided with an insertion cavity 11. In this embodiment, the insertion cavity 11 has openings along the top and the front side. The side walls on the left and right sides of the insertion cavity 11 form a guide rail 12. The guide rail 12 is provided with a horizontal guide surface 121 parallel to the first direction, and the horizontal guide surface 121 faces upward. A first inclined surface 13 is provided at the bottom of the insertion cavity 11. The first inclined surface 13 faces the first sealing portion 4 and gradually approaches the moving part 2 located above the first inclined surface 13 along the first direction. In this embodiment, the first direction is from front to back. The closer the first inclined surface 13 is to the rear side, the closer the distance to the moving part 2 is. The main body 1 is also provided with a first through hole 14, and the upper end of the first through hole 14 opens to the first inclined surface 13. Reference Figure 8 , guide slide holes 15 are also provided on the left and right side walls of the body 1, and the guide slide holes 15 include a first section 151 and a second section 152 which are interconnected and arranged in sequence along the first direction, the first section 151 is provided with a first upward supporting surface 1511, and the second section 152 is provided with a second upward supporting surface 1521, the first section 151 is an inclined section, the first section 151 extends along the first direction and is inclined upward; the second section 152 is a horizontal section and is higher than the first section 151. In other embodiments, the first section 151 and the second section 152 may be perpendicular to each other. Of course, the second section 152 may also be an inclined section inclined downward, as long as the bottom of the second section 152 is higher than the bottom of the first section 151.

[0053] The moving member 2 is located in the insertion cavity 11, or the moving member 2 has a portion that can extend into the insertion cavity 11 (the portion is used to press the second sealing portion 5) to seal with the inserting member 3 in the insertion cavity 11. The moving member 2 is suitable for moving between the first position and the second position relative to the body 1. In this embodiment, the reference Fig. 9 The moving part 2 is a wind chamber module, which has a ventilation chamber 21 and is located above the insert 3. A fan is installed in the ventilation chamber 21 for heat dissipation. In other embodiments, the moving part 2 may be located below the insert 3. In this embodiment, the wind chamber module is slidably connected to the body 1 to move between the first position and the second position. For details, refer to Figure 8 , the moving part 2 is provided with a guide post 22 that slidably cooperates with the guide sliding hole 15. When the moving part 2 slides in the first position, the guide post 22 is located at the bottom of the first section 151 and is supported by the first support surface 1511. When the moving part 2 slides in the second position, the guide post 22 is located in the second section 152 and is supported by the second support surface 1521. Therefore, in this embodiment, when the moving part 2 slides to the second position, it slides upward and backward, and vice versa. In other embodiments, the moving part 2 can also slide only between the first position and the second position in the up and down direction. It should be understood that in other embodiments, the above effect can also be achieved by providing the moving part 2 with a sliding hole and the main body 1 with a guide post 22. In other embodiments, the moving part 2 can also be rotatably connected to the main body 1 to move between the first position and the second position.

[0054] refer to Figure 3-Figure 6 The insert 3 is suitable for being inserted into the insertion cavity 11 along the first direction, and the two ends of the second direction perpendicular to the first direction are respectively provided with a first sealing area 31 and a second sealing area 32. The second direction can be the up-down direction or the left-right direction. In this embodiment, the second direction is the up-down direction. The first sealing area 31 and the second sealing area 32 can be vias connected to the chambers of the body 1 and the moving part 2, or can be precision parts that need to be waterproof and dustproof, such as a charging seat. In this embodiment, reference Fig. 9 The insert 3 is a power module, and the first sealing area 31 and the second sealing area 32 are via holes connected to the first through hole 14 and the ventilation cavity 21, respectively, for heat dissipation of the power module. Figure 3 The bottom of the insert 3 is provided with a second inclined surface 33 adapted to the first inclined surface 13 , and the second inclined surface 33 and the first inclined surface 13 are parallel to each other.

[0055] refer to Figure 3 , Figure 6 The left and right sides of the insert 3 are respectively provided with sliders 34 suitable for sitting on the horizontal guide surface 121, and the sliders 34 are suitable for sliding along the horizontal guide surface 121 to allow the insert 3 to be inserted into the insertion cavity 11 along the first direction, or to exit the insertion cavity 11 in the opposite direction of the first direction.

[0056] refer to Figure 1 , Figure 2 and Fig.11 , the first sealing portion 4 is provided on the body 1, the first sealing portion 4 is flexible, and the first sealing portion 4 surrounds the outside of the first sealing area 31 to achieve the sealing of the first sealing area 31. In other embodiments, the first sealing portion 4 can also be provided on the insert 3. In this embodiment, the first sealing portion 4 is formed by an annular sealing rubber strip. In other embodiments, when the body 1 or the insert 3 has a flexible end surface, the first sealing portion 4 can also be formed by the flexible end surface. The insert 3 is seated on the horizontal guide surface 121 and slides along the horizontal guide surface 121 until the two ends of the first sealing portion 4 are respectively suitable for abutting against the first inclined surface 13 of the body 1 and the second inclined surface 33 of the insert 3, so as to achieve the sealing of the first sealing area 31.

[0057] refer to Figure 3 , Figure 4 and Fig.10, the second sealing portion 5 is arranged above the insert 3, the second sealing portion 5 is flexible, and surrounds the outside of the second sealing area 32; in other embodiments, the second sealing portion 5 can also be arranged below the moving part 2. In this embodiment, the second sealing portion 5 is also formed by an annular sealing strip. When the moving part 2 moves to the first position, the moving part 2 and the insert 3 respectively press against the two ends of the second sealing portion 5; in the second position, the moving part 2 is away from the insert 3, so that the second sealing portion 5 is separated from the moving part 2 and the insert 3 to allow the insert 3 to withdraw from or insert the insertion cavity 11. In this embodiment, since the moving part 2 is in a common state when it is in the first position, in order to prevent the elasticity of the second sealing portion 5 from causing the moving part 2 to move, resulting in a poor sealing effect, the moving part 2 needs to at least stop at the first position to ensure the sealing effect. Specifically, when the moving part 2 is in the first position, it stops at the first position by gravity and / or by being detachably fixed to the body 1 or the insert 3. The moving part 2 is fixedly connected to the body 1 or the inserting part 3 in a detachable manner, including but not limited to a snap connection, a screw connection, a magnetic connection, etc.

[0058] In this embodiment, the moving part 2 is located above the inserting part 3, so the gravity of the moving part 2 is applied to the second sealing part 5, so that the moving part 2 and the inserting part 3 can be respectively against the two ends of the second sealing part 5. Furthermore, by passing the screw through the inserting part 3 and locking it with the moving part 2 (or by a nut), the second sealing part 5 can be further compressed to improve the sealing effect and limit the movement of the moving part 2 relative to the inserting part 3. Similarly, in order to limit the movement of the inserting part 3 relative to the body 1, the inserting part 3 and the body 1 can also be locked by screws.

[0059] When in use, first push the moving part 2 backwards to make it slide to the second position. At this time, the size of the insertion cavity 11 is larger than the insert 3, which is convenient for insertion. The insert 3 is located on the horizontal guide surface 121 and slides along the horizontal guide surface 121 until the two ends of the first sealing part 4 are respectively suitable for abutting against the first inclined surface 13 of the body 1 and the second inclined surface 33 of the insert 3, so as to achieve the sealing of the first sealing area 31. Then push the moving part 2 forwards to make it move to the first position. The moving part 2 gradually approaches the insert 3, and the two ends of the second sealing part 5 are respectively against the moving part 2 and the insert 3, so as to achieve the sealing of the second sealing area 32. Finally, the moving part 2 and the insert 3, and the insert 3 and the body 1 are screwed together to complete the installation.

[0060] During disassembly, first remove the screws, then push the moving part 2 backwards to make the moving part 2 slide to the second position, and then the insert 3 slides along the horizontal guide surface 121 and withdraws from the insertion cavity 11, thereby completing the disassembly of the insert 3.

[0061] Compared with the prior art, this embodiment has the following beneficial effects:

[0062] In an exemplary embodiment, a sealing assembly includes a body 1 , a moving part 2 and an insert 3 .

[0063] The body 1 is provided with an insertion cavity 11; the moving part 2 is suitable for moving between a first position and a second position relative to the body 1, so as to be suitable for approaching or moving away from the insert 3. The insert 3 is suitable for being inserted into the insertion cavity 11 along a first direction, and its two ends in a second direction perpendicular to the first direction are respectively provided with a first sealing area 31 and a second sealing area 32, a first sealing portion 4 is provided on the body 1 or the insert 3, and surrounds the outside of the first sealing area 31, and the body 1 and the insert 3 respectively press the two ends of the first sealing portion 4 to achieve the sealing of the first sealing area 31; the second sealing portion 5 is provided on the insert 3 or the moving part 2, and surrounds the outside of the second sealing area 32; when the moving part 2 moves to the first position, the moving part 2 and the insert 3 respectively press the two ends of the second sealing portion 5 to achieve the sealing of the second sealing area 32, and the moving part 2 is at least suitable for stopping at the first position, so as to prevent the second sealing portion 5 from rebounding and causing the sealing failure of the second sealing area 32. When in the second position, the moving part 2 is away from the inserting part 3, so that the second sealing portion 5 is released from the pressure against the moving part 2 and the inserting part 3, so that the size of the insertion cavity 11 can be larger than the size of the inserting part 3, which facilitates the insertion or withdrawal of the inserting part 3 into the insertion cavity 11 and realizes installation or disassembly, thereby satisfying both sealing and easy disassembly.

[0064] In an exemplary embodiment, the moving member 2 is rotationally connected or slidably connected to the body 1 to move between a first position and a second position to achieve a position change.

[0065] In an exemplary embodiment, the moving part 2 is located above or below the insert 3, and the moving part 2 is slidably connected to the main body 1. The moving part 2 is slidably connected to the main body 1, and the moving part 2 is supported by the main body 1 when it is in the first position and the second position, so that the moving part 2 has a support position at both positions and will not slide due to its own gravity. Therefore, when installing or removing the insert 3, there is no need to always maintain the position of the moving part 2, which is more convenient.

[0066] In an exemplary embodiment, one of the main body 1 and the moving part 2 is provided with a guide hole 15, and the other is provided with a guide column 22 that slidably cooperates with the guide hole 15. The guide hole 15 includes a first section 151 and a second section 152 that are interconnected and arranged in sequence along a first direction. The first section 151 and the second section 152 are respectively provided with a first supporting surface 1511 and a second supporting surface 1521. When the moving part 2 slides between the first position and the second position, it is supported by the first supporting surface 1511 and the second supporting surface 1521 respectively, so as to realize support and movement guidance at the two positions.

[0067] In an exemplary embodiment, the first section 151 is an inclined section, which extends along a first direction and tilts upward, and the second section 152 is a horizontal section. The corresponding position change can be achieved directly by pushing and pulling along the first direction or the first direction without lifting upward, which is more convenient and particularly suitable for use in narrow electrical cabinets with only one side having operating space.

[0068] In an exemplary embodiment, when the moving part 2 is in the first position, it is docked at the first position by gravity and / or detachable connection with the main body 1 or the insert 3, thereby fixing the position of the moving part 2 and ensuring the stability of the seal during use.

[0069] In an exemplary embodiment, a first inclined surface 13 is provided on the surface of the main body 1 facing the first sealing portion 4, and the first inclined surface 13 gradually approaches the moving part 2 along the first direction, and the insert 3 is provided with a second inclined surface 33 adapted to the first inclined surface 13. The extension direction of the first sealing portion 4 is the same as the extension direction of the first inclined surface 13, and the two ends are respectively suitable for abutting against the first inclined surface 13 and the second inclined surface 33, so that the insert 3 is pressed against the first sealing portion 4 only when the insertion is completed to achieve sealing, prevent damage to the first sealing portion 4 during the insertion process, and facilitate insertion and installation. Conversely, it is also convenient for disassembly.

[0070] In an exemplary embodiment, the insert 3 is usually cantilevered relative to the force application position (such as the hand). If the weight of the insert 3 is large, the insert 3 is easy to tilt, resulting in inconvenience in installation or removal. The insertion cavity 11 is provided with a horizontal guide surface 121 parallel to the first direction. The insert 3 is suitable for sitting on the horizontal guide surface 121 and sliding along the horizontal guide surface 121 until the two ends of the first sealing portion 4 are respectively suitable for abutting against the first inclined surface 13 and the second inclined surface 33. During the plug-in process, the insert 3 is supported by the horizontal guide surface 121, which can be more convenient for assembly and disassembly.

[0071] In an exemplary embodiment, an electrical cabinet includes the above-mentioned sealing assembly, the insert 3 is a power module, and the moving part 2 is an air cavity module, which has the beneficial effects brought by the above-mentioned sealing assembly.

[0072] Embodiment 2:

[0073] In the first embodiment, the sealing of the first sealing area 31 and the second sealing area 32 are independent of each other and do not affect each other. In this embodiment, in the process of achieving the sealing of the second sealing area 32, the sealing effect of the first sealing area 31 is also improved. Specifically, in the process of the moving part 2 moving to the first position, the inserting part 3 is pressed to make the inserting part 3 approach the body 1, and the body 1 and the inserting part 3 are respectively pressed against the two ends of the first sealing part 4 to further compress the first sealing part 4, so that the sealing effect of the first sealing area 31 is better.
