[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model embodiment discloses a metal packaging shell of an integrated circuit device. Figure 1-5 A metal package shell of an integrated circuit device comprises a shell 1, a shell cover 2 is arranged at the upper end of the shell 1, and limit grooves 3 are provided at the upper ends of the left and right sides of the shell 1, and a positioning mechanism 4 is arranged in the limit groove 3 for limiting the shell cover 2 covered on the shell 1, and multiple sets of guide mechanisms 5 are arranged on the outer side of the shell 1 for positioning the shell cover 2;

[0030] Reference Figure 3 and Figure 5The positioning mechanism 4 includes a positioning block 401, a slider 402 and a spring 403. The positioning block 401 is arranged on the outside of the shell 1 and one end of the positioning block 401 passes through the inside of the limiting groove 3. The end of the positioning block 401 away from the limiting groove 3 is in a slope shape. The slider 402 is slidably arranged in the inside of the limiting groove 3. One side of the slider 402 is connected to the positioning block 401 for limiting the positioning block 401. The spring 403 is arranged in the inside of the limiting groove 3. The end of the spring 403 away from the inner wall of the limiting groove 3 is connected to the slider 402 for resetting the slider 402 after moving; positioning ports 6 for use with the positioning block 401 are provided on the left and right sides of the shell cover 2, and the end of the positioning block 401 away from the slider 402 is plugged into the positioning port 6. A baffle 7 is rotatably arranged on the outside of the shell cover 2 at the positioning port 6 for protecting the positioning block 401.

[0031] By adopting the above technical solution, when the shell cover 2 is closed on the upper part of the shell body 1, the positioning block 401 will be squeezed as the shell cover 2 moves downward. When the shell cover 2 is closed on the shell body 1, the positioning block 401 can be inserted into the positioning port 6 by utilizing the elastic force of the spring 403, so that the shell cover 2 can be limited and fixed. When the shell cover 2 is disassembled, it is only necessary to rotate the baffle 7 and press the positioning block 401 so that the positioning block 401 is moved out of the positioning port 6 to disassemble the shell cover 2, which is simple and convenient.

[0032] Reference Figure 2 and Figure 3 The guide mechanism 5 includes a guide block 501 and a limit stop block 502. The guide block 501 is arranged on the outside of the shell 1, and the limit stop block 502 is arranged at the end of the guide block 501 away from the shell 1; the bottom end of the shell cover 2 is provided with a plurality of rectangular openings 8 for use with the guide block 501, the guide block 501 is plugged into the rectangular openings 8, and the limit stop block 502 is in contact with the outside of the shell cover 2.

[0033] By adopting the above technical solution, when the shell cover 2 is closed on the upper part of the shell body 1, the rectangular opening 8 is aligned with the guide block 501, making it more convenient to close the shell cover 2 on the shell body 1. At the same time, the limit stop block 502 is used to prevent the shell cover 2 from shifting when it is closed on the shell body 1.

[0034] Reference Figure 3 and Figure 4 A rectangular groove 9 is provided at the upper end of the shell 1, a sealing gasket 10 is arranged inside the rectangular groove 9, and a sealing frame 11 used in conjunction with the rectangular groove 9 is provided at the inner top end of the shell cover 2, and the bottom end of the sealing frame 11 is inserted into the interior of the rectangular groove 9 and fits with the sealing gasket 10.

[0035] By adopting the above technical solution, after the shell cover 2 is covered on the housing 1, the sealing frame 11 is inserted into the rectangular groove 9 and fits with the sealing gasket 10, thereby ensuring the sealing performance after the shell cover 2 is covered on the housing 1.

[0036] Reference Figure 4 A plurality of pin through holes 12 are provided at the bottom end of the housing 1 .

[0037] By adopting the above technical solution, pins on the integrated circuit device installed inside the housing 1 can pass through.

[0038] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch, the integrated circuit device is installed inside the housing 1, and the pins on the integrated circuit device can pass through the pin through-holes 12, and then the shell cover 2 is closed on the housing 1, so that the rectangular opening 8 on the shell cover 2 is aligned with the guide block 501, and then the shell cover 2 is closed on the upper end of the housing 1, and as the shell cover 2 gradually moves downward, the positioning block 401 is squeezed, and the positioning block 401 is squeezed and slides into the limiting groove 3 and squeezes the spring 403, and when the top end of the rectangular opening 8 contacts the guide block 501, the sealing frame 11 is inserted into the rectangular opening 8. The groove 9 fits with the sealing gasket 10, and the positioning port 6 moves to the positioning block 401, so that the squeezing force on the positioning block 401 disappears, and then the positioning block 401 can be inserted into the positioning port 6 through the elastic force of the spring 403, and the shell cover 2 can be limited and fixed, so that the stability of the shell cover 2 on the shell 1 is guaranteed. When the shell cover 2 needs to be removed from the shell 1, the baffle 7 is rotated and the staff presses the positioning block 401 to move it out of the positioning port 6. At this time, the limit on the shell cover 2 is cancelled, so that the shell cover 2 can be removed from the shell 1 by pulling it upwards. It is simple and convenient, and the difficulty of disassembly and assembly between the shell 1 and the shell cover 2 is greatly reduced.

[0039] When the utility model is in use, the assembly and disassembly between the shell 1 and the shell cover 2 is simpler and more convenient, and the connection between the shell cover 2 and the shell 1 is more stable after the shell cover 2 is covered on the shell 1.
