Abstract
Description
Technical Field
[0001] This application relates to the field of metal packaging housing technology, and in particular to a metal packaging housing that is easy to assemble. Background Technology
[0002] As a key component of integrated circuits, metal encapsulation shells mainly play a role in circuit support, electrical signal transmission, heat dissipation, sealing, and chemical protection. The shell plays an important role in the reliability of the circuit and its proportion of the circuit cost. A metal encapsulation shell is a protective shell made primarily of metal and assembled in a closed manner using encapsulation technology. Metal encapsulation shells provide many conveniences for encapsulation.
[0003] Existing metal enclosures are typically assembled using bolts, which makes assembly and disassembly cumbersome and reduces the practicality of the device.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To address the problem that existing metal enclosures typically require bolts for assembly, which makes assembly and disassembly cumbersome and reduces the practicality of the device, this application provides a metal enclosure that is easy to assemble.
[0006] The metal encapsulation shell provided in this application, which is easy to assemble, adopts the following technical solution:
[0007] A metal encapsulation shell that is easy to assemble includes a lower shell. A mating groove is formed on the inner wall of the top of the lower shell. A fixing frame is fixedly engaged in the mating groove by a snap-fit assembly. An upper shell cover is fixedly connected to the top of the fixing frame. The snap-fit assembly includes a snap-fit post that penetrates the lower shell. A moving groove is formed on the outer side of the lower shell located on the snap-fit post. A moving block is slidably disposed inside the moving groove. The moving block is fixedly connected to the snap-fit post. A spring is provided between the moving block and the side wall of the moving groove. A snap-fit groove that mates with the snap-fit post is formed on the outer wall of the fixing frame.
[0008] Preferably, the end of the snap-fit post is fixedly inserted through the side wall of the lower housing and is fixedly connected to a pull plate.
[0009] Preferably, a first sealing gasket is installed at the bottom of the fixing frame, and the first sealing gasket is in contact with the bottom wall of the mating groove.
[0010] Preferably, a second sealing gasket is installed between the upper cover and the lower cover.
[0011] In summary, this application includes the following beneficial technical effects:
[0012] 1. This application provides a snap-fit post on the lower housing, along with a movable groove, a movable block, a spring, a fixed frame, and a snap-fit groove. This allows the spring to push the movable block to drive the snap-fit post into the snap-fit groove, thus achieving a fixed connection between the upper housing cover and the lower housing. Conversely, pulling the snap-fit post can separate the upper housing cover from the lower housing, improving the ease of device assembly.
[0013] 2. This application improves the sealing performance between the upper and lower housings by installing a second sealing gasket on the upper housing cover and a first sealing gasket on the bottom wall of the fixed frame, thus ensuring the sealing effect of the device.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0020] This application discloses a metal packaging shell that is easy to assemble, referring to... Figure 1-4 The device includes a lower housing 1. A mating groove 11 is provided on the inner wall of the top of the lower housing 1. A fixing frame 21 is fixedly connected to the mating groove 11 by a snap-fit assembly 3. An upper housing cover 2 is fixedly connected to the top of the fixing frame 21. The snap-fit assembly 3 includes a snap-fit post 31 that penetrates the lower housing 1. A moving groove 32 is provided on the outer side of the snap-fit post 31 on the lower housing 1. A moving block 33 is slidably provided inside the moving groove 32. The moving block 33 is fixedly connected to the snap-fit post 31. A spring 34 is provided between the moving block 33 and the side wall of the moving groove 32. A snap-fit groove 22 that mates with the snap-fit post 31 is provided on the outer wall of the fixing frame 21.
[0021] Here, by pulling the locking pin 31, the locking pin 31 causes the moving block 33 to compress the spring 34 and retract it into the moving groove 32. Then, the fixing frame 21 installed on the bottom wall of the upper shell cover 2 is inserted into the mating groove 11. When the locking pin 31 is released, the spring 34 returns to its original shape and can push the moving block 33 and the locking pin 31 into the locking groove 22, thereby fixing the upper shell cover 2. Conversely, by pulling the locking pin 31 away from the locking groove 22, the upper shell cover 2 can be separated from the lower shell 1.
[0022] Reference Figure 4 The end of the snap-fit post 31 is fixedly inserted through the side wall of the lower housing 1 and is fixedly connected to the pull plate 35.
[0023] The pull plate 35 is provided here to facilitate the movement of the locking post 31.
[0024] Reference Figure 2 A first sealing gasket 23 is installed at the bottom of the fixed frame 21, and the first sealing gasket 23 is in contact with the bottom wall of the mating groove 11.
[0025] The first sealing gasket 23 is provided here to improve the sealing performance of the device and ensure the sealing effect of the device.
[0026] Reference Figure 1 and Figure 2 A second sealing gasket 24 is installed between the upper cover 2 and the lower cover 1.
[0027] The second sealing gasket 24 is provided here, which can further improve the sealing performance of the device.
[0028] The implementation principle of the easily assembled metal encapsulation shell of this application embodiment is as follows: When in use, the device is placed in the designated position, and then the pull plate 35 is pulled to retract the locking post 31 into the moving groove 32. Then, the fixing frame 21 installed on the bottom wall of the upper shell cover 2 is inserted into the mating groove 11. When the locking post 31 is released, the spring 34 returns to its deformation, which can push the moving block 33 and the locking post 31 into the locking groove 22, thereby fixing the upper shell cover 2. Conversely, pulling the locking post 31 away from the locking groove 22 can separate the upper shell cover 2 from the lower shell 1.
