DETAILED DESCRIPTION

[0026] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0027] Example 1

[0028] like Figure 1-Figure 2 As shown, in this embodiment, a heat dissipation shell and a rectifier thereof are provided, including a shell 1, at least one side of the shell 1 is spliced ​​by a detachable movable plate 2, both ends of the movable plate 2 are fixedly connected with plug blocks 3, and a plug hole 4 matching with the plug block 3 is opened on the side wall of the shell 1, as shown in FIG. Figure 2 As shown, one movable plate 2 corresponds to two sockets 4, and the inserting directions of the inserting blocks 3 at both ends of the movable plate 2 into the corresponding sockets 4 are the same, that is, after the movable plate 2 is fitted on the side of the shell 1, the movable plate 2 is slid to make the inserting blocks 3 slide toward the sockets 4. When the inserting blocks 3 are inserted into the inside of the sockets 4, the movable plate 2 is spliced ​​on the shell 1. At this time, the movable plate 2 covers one side of the shell 1. Conversely, after the movable plate 2 is slid in the opposite direction, the inserting blocks 3 slide out from the inside of the sockets 4. At this time, the movable plate 2 can be quickly removed from the shell 1, which improves the convenience of disassembly and assembly of the movable plate 2, and the movable plate 2 is fixed to the shell 1 through the fixing assembly after splicing;

[0029] Among them, the surface of the movable plate 2 is equidistantly fixed with heat dissipating fins 5, which can effectively dissipate the heat in the shell 1, thereby achieving the purpose of heat dissipation in the shell 1, improving the heat dissipation efficiency of the inner cavity of the shell 1, and helping to maintain the stable operation of the equipment in the shell 1, and the heat dissipating fins 5 are arranged on the movable plate 2. After the movable plate 2 is removed, the heat dissipating fins 5 can be removed from the shell 1 along with the movable plate 2, so as to clean the heat dissipating fins 5.

[0030] like Figure 2 As shown, in order to connect the two sides of the movable plate 2 to the housing 1 and prevent the two sides of the movable plate 2 from tilting, a plurality of pin blocks 6 are fixedly connected to the two sides of the movable plate 2, and a pin slot 7 for inserting the pin block 6 is provided on the side wall of the housing 1, and the pin slot 7 includes a transverse slot 701, which is provided on the side wall of the housing 1 along the sliding direction of the movable plate 2, and a notch 702 for the pin block 6 to enter the transverse slot 701 is provided on the transverse slot 701;

[0031] The process of splicing the movable plate 2 onto the shell 1 is as follows:

[0032] When placing the movable plate 2, align the pin block 6 on the movable plate 2 with the corresponding notch 702, and press the movable plate 2 toward the housing 1. At this time, the movable plate 2 fits on the side of the housing 1, and the pin block 6 slides from the notch 702 into the inside of the transverse groove 701. As the movable plate 2 slides on the housing 1 and the plug block 3 is inserted into the inside of the insertion hole 4, at the same time, after the pin block 6 slides inside the transverse groove 701, the pin block 6 and the transverse groove 701 are staggered. At this time, under the cooperation of the pin block 6 and the transverse groove 701, the two sides of the movable plate 2 can be prevented from warping.

[0033] When removing the movable plate 2 , the movable plate 2 is slid in the reverse direction. At this time, the movable plate 2 drives the insert block 3 to slide out of the insert hole 4 , and at the same time, the pin block 6 slides to align with the notch 702 , so that the movable plate 2 can be removed from the housing 1 .

[0034] An ear plate 11 is provided on the shell 1, and a mounting hole 12 is opened on the ear plate 11. The ear plate 11 can be used to conveniently install and fix the shell 1 to other devices or components. The mounting hole 12 provides an interface for use with fasteners, so that the shell 1 can be firmly fixed in the desired position.

[0035] A wire hole 13 is provided on the side wall of the housing 1 for connecting or passing various cables, such as power cables, data cables or signal cables, to achieve electrical connection between the rectifier and external devices.

[0036] Example 2

[0037] like Figure 2-Figure 4As shown, on the basis of Example 1, in order to more stably fix the movable plate 2 spliced ​​on the shell 1, a plurality of bolts 8 are meshed and connected on the side wall of the movable plate 2. When the movable plate 2 is spliced ​​on the shell 1, the threaded ends of the bolts 8 are meshed and connected to the side wall of the shell 1 to fix the movable plate 2 on the shell 1.

[0038] Example 3

[0039] like Figure 5-Figure 8 As shown, on the basis of Example 1, in order to fix the movable plate 2 spliced ​​on the shell 1 more stably, a U-shaped elastic spring sheet 9 is fixed on the side wall of the shell 1, a hook 901 is fixed on the end of the elastic spring sheet 9, and a slot 201 adapted to the hook 901 is opened on the side wall of the movable plate 2. When the movable plate 2 is spliced ​​on the hook 901, the hook 901 is snapped into the inside of the slot 201 to fix the movable plate 2 on the shell 1;

[0040] When the movable plate 2 slides along the side wall of the shell 1 so that the plug block 3 is inserted into the inside of the socket 4, the hook 901 of the elastic spring 9 will also enter the range of the slot 201. Due to the elasticity of the elastic spring 9, the hook 901 will bend slightly inward, and then when the hook 901 is aligned with the slot 201, the hook 901 will quickly return to its original shape and be firmly connected to the slot 201. In this way, the movable plate 2 is stably fixed on the shell 1.

[0041] like Figure 7 , Figure 8 As shown, in order to fix the elastic spring 9 on the shell 1, one side of the elastic spring 9 is fixed to the side wall of the shell 1 by a screw 10, and the other side of the elastic spring 9 is provided with a waist-shaped groove 902 for convenient installation of the screw 10. The waist-shaped groove 902 can provide sufficient installation space for the screw 10, so that the screw 10 can pass through and be fixed on the shell 1 smoothly.

[0042] like Figure 5-8 As shown, in order to disengage the hook 901 from the slot 201 so as to remove the movable plate 2, a pressure plate 202 capable of generating deformation is provided on the side wall of the movable plate 2 close to the slot 201. When the movable plate 2 is spliced ​​on the housing 1, the pressure plate 202 is attached to the outer wall of the elastic spring 9.

[0043] When the movable plate 2 needs to be removed, the user only needs to press the pressure plate 202 slightly to cause it to deform and push the elastic spring 9 to bend inward. Since the elastic spring 9 is elastic, when the pressure plate 202 applies pressure, it will temporarily change its shape, causing the hook 901 to disengage from the slot 201. At this time, the user can easily slide the movable plate 2 to remove it from the shell 1.

[0044] Example 4

[0045] like Figure 2 , Figure 3 As shown, a rectifier is installed in the heat dissipation shell described in Example 1, Example 2 or Example 3.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
