[0031] The present application will be further described below in conjunction with the drawings:

[0032] As Figures 1 to 10As shown, a preferred embodiment of the present application comprises a box body 1, a containing groove 11 is arranged in the box body 1, a sealing groove 12 is arranged outside the opening of the containing groove 11, a sealing strip 2 is adapted to be installed in the sealing groove 12, at least one connecting hole 13 is arranged on one side of the sealing groove 12, the number of the connecting holes 13 is preferably multiple, a connecting column 3 is adapted to be installed in the connecting hole 13, a slidable locking piece 4 is arranged on the box body 1, the same number of unlocking grooves 41 and locking grooves 42 as the connecting holes 13 are arranged on the locking piece 4, when the unlocking groove 41 moves to the connecting hole 13, the connecting column 3 is adapted to pass through the block of the sealing strip 2 and extend into the connecting hole 13, when the locking groove 42 moves to the connecting hole 13, the sealing strip 2 is adapted to prevent the connecting column 3 from leaving the connecting hole 13.

[0033] One connecting hole 13 corresponds to one unlocking groove 41 and one locking groove 42 respectively, the depth of the unlocking groove 41 is greater than that of the locking groove 42, when the unlocking groove 41 is located at the connecting hole 13, the connecting column 3 can press the sealing strip 2 to deform into the unlocking groove 41, and the excess amount generated by the deformation enters the connecting hole 13, when the locking groove 42 is located at the connecting hole 13, the locking groove 42 can press the sealing strip 2 in the connecting hole 13, so that the sealing strip 2 is interference fit with the connecting column 3, the friction force is improved, thereby realizing the fixation of the connecting column 3 in the connecting hole 13, and the interference fit deformation of the sealing strip 2 can also improve the sealing capacity and improve the airtight protection performance to protect the inductance in the containing groove 11.

[0034] The number of the connecting holes 13 is even, the connecting holes 13 are distributed on both sides of the opening of the containing groove 11, the locking piece 4 comprises two locking arms 43, the two locking arms 43 are adapted to be slidably inserted into both sides of the opening of the containing groove 11, only the openings on both sides of the containing groove 11 need to be locked, and the entire containing groove 11 can be closed, the unlocking grooves 41 and the locking grooves 42 are arranged on the locking arms 43, by switching the positions of the unlocking grooves 41 and the locking grooves 42 relative to the connecting holes 13, the interference fit degree of the sealing strip 2 to the connecting column 3 can be changed, and the pressing fixation can be realized.

[0035] As shown, Figure 8 The locking piece 4 comprises a control part 44, the control part 44 is connected with the locking arm 43, the control part 44 is located outside the box body 1, when the control part 44 abuts against the box body 1, the locking groove 42 is adapted to move to the connecting hole 13, in use, only the control part 44 needs to be pressed into the box body 1 to be unable to move, and the locking can be realized, which is simple and convenient to operate.

[0036] An upwardly curved operation part 441 is arranged on the control part 44, when the control part 44 abuts against the box body 1, an operation gap 45 is formed between the operation part 441 and the box body 1, by using the operation gap 45, the control part 44 can be outwardly pried to take out the locking piece 4.

[0037] A first insertion groove 21 is provided on the outer side of the sealing strip 2. The locking arm 43 is adapted to be inserted into the first insertion groove 21. The setting of the first insertion groove 21 can make the locking arm 43 closer to the connection hole 13. The movement of the unlocking groove 41 and the locking groove 42 on the locking arm 43 can be fed back to the connection hole 13 more directly through the sealing strip 2, so as to realize the effective unlocking or locking of the connecting post 3.

[0038] A second insertion groove 121 is provided on the other side of the sealing groove 12. The locking arm 43 is adapted to be inserted into the first insertion groove 21 and the second insertion groove 121, which can prevent the sealing strip 2 from falling out of the sealing groove 12, improve the firmness and stability of the sealing strip 2 during the disassembly and assembly process, and at the same time effectively utilize the limited space of the box 1 outside the sealing groove 12 to increase the width of the locking arm 43 and improve the structural strength of the locking arm 43.

[0039] The sealing groove 12 is preferably a parallelogram. The sealing groove 12 is arranged around the receiving groove 11. The connecting hole 13 and the locking arm 43 are arranged along the two longer sides of the sealing groove 12. The regular shape of the sealing groove 12 makes it easier to set the locking arm 43. The fact that the connecting hole 13 is arranged along the longer side can increase the number of connecting holes 13, so that the connection points can cover more area, thereby improving the installation and connection stability of the box 1.

[0040] The sealing strip 2 has a rectangular cross-section and is preferably made of rigid material. The projection of the sealing strip 2 at the connecting hole 13 overlaps. When the connecting post 3 extends into the connecting hole 13, the sealing strip 2 will have an interference fit with the connecting post 3. When the locking groove 42 moves to the connecting hole 13, the degree of interference fit can be deepened, thereby achieving a tight fit between the connecting post 3 and the connecting hole 13.

[0041] The sealing strip 2 is preferably slightly higher than the sealing groove 12, which can provide an overall seal for the box body 1 and achieve a stronger sealing effect.

[0042] The sealing strip 2 has a guide groove 22 on the side of the connecting post 3 near the connecting hole 13. The guide groove 22 can help the connecting post 3 enter the connecting hole 13 and prevent the sealing strip 2 from being excessively squeezed and causing the sealing strip 2 to fall out of the sealing groove 12.

[0043] The connecting post 3 is provided with a snap-fit ​​groove 31. When the connecting post 3 is inserted into the connecting hole 13, the sealing strip 2 is adapted to fit into the snap-fit ​​groove 31. The snap-fit ​​groove 31 can cooperate with the sealing strip 2 to improve the connection stability of the connecting post 3. The hardness of the sealing strip 2 itself and the pressure of the locking member 4 are used to snap and fix the connecting post 3, so as to prevent the connecting post 3 from falling out of the connecting hole 13.

[0044] like Figure 9As shown, there are multiple connecting holes 13, including a first positioning hole 31 and a second positioning hole 32. The cross-sectional shape of the second positioning hole 32 is different from that of the first positioning hole 31. The installation direction of the box 1 is limited by the two different shapes of positioning holes to avoid the box 1 being installed backwards or incorrectly. The first positioning hole 31 is preferably circular, and the second positioning hole 32 is preferably gourd-shaped.

[0045] like Figure 10 As shown, multiple first heat dissipation fins 15 are equally spaced along the horizontal direction on both sides of the box body 1. The first heat dissipation fins 15 and the top of the box body 1 cooperate to form a heat dissipation surface 151. Multiple second heat dissipation fins 16 are equally spaced along the vertical direction on the heat dissipation surface 151. By fully utilizing the structure formed between the first heat dissipation fins 15 and the box body 1, a flat heat dissipation surface 151 is formed, thereby increasing the number of second heat dissipation fins 16 that can be set and improving heat dissipation efficiency. After the first heat dissipation fins 15 and the second heat dissipation fins 16 are combined, the shape of the entire box body 1 can be closer to a cuboid structure, which is more regular and convenient for placement inside the equipment.

[0046] The housing 1 has a mounting base 14 formed upward at the opening of the receiving groove 11. The mounting base 14 is integrally connected to the bottom first heat dissipation fin 15. The connection hole 13 is set in the mounting base 14. The mounting base 14 can be integrally die-cast with the housing 1. It can also improve the structural strength of the mounting base 14 through the connection with the first heat dissipation fin 15, thereby improving the stability of the connection hole 13. The mounting base 14 itself can also increase the heat dissipation surface area of ​​the housing 1 and improve the heat dissipation efficiency.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
