Description

Technical Field

[0001] The utility model relates to the technical field of ceramic packaging shell production, in particular to a ceramic packaging shell which is easy to disassemble and assemble. Background Art

[0002] Ceramic packaging shells are widely used in device packaging such as hybrid integrated circuits, optoelectronic devices, surface acoustic wave devices, Hall devices, crystal oscillators and solid-state relays due to their superior high air tightness, high thermal conductivity, high moisture resistance, high mechanical strength, and high insulation resistance.

[0003] In the comparative document of a heat dissipation ceramic package shell proposed with publication number CN216818322U, it is specifically proposed that "it includes a package shell, a chip, a heat sink, a ground pin, a package board and an insert board, the top of the package shell is an open structure, the chip is fixedly arranged in the package shell, the heat sink is fixedly passed through the bottom of the package shell, the top of the heat sink is fixedly connected to the bottom of the chip, the bottom of the package shell is fixedly provided with a ground pin, two grooves are provided on both sides of the top of the package shell, and two insert boards corresponding to the two grooves are fixedly provided at the bottom of the package board, and the two insert boards are movably embedded in the two grooves."

[0004] The inventors found that in the comparative document, the plug-in board is inserted into the packaging shell, and then the clamping seat is inserted into the card seat by rotating the handle for fixing. Since the volume of the packaging shell and the chip is very small, it is inconvenient to rotate the handle manually or with tools. Therefore, we propose a ceramic packaging shell that is easy to disassemble and assemble. Utility Model Content

[0030] It is worth mentioning here that the triangular cone block 93 is squeezed by the packaging plate 2 during the downward pressing process, and the triangular cone block 93 is squeezed toward the middle spring. When the triangular cone block 93 is not subjected to pressure from both sides, the triangular cone block 93 is reset by the reset spring a95 to lock the shell 1.

[0031] Reference Figure 4 The unlocking assembly 11 includes a support rod 111 slidably set in a sliding groove, a rectangular column 112 symmetrically set at the end of the support rod 111, a limit block 113 set at the other end of the support rod 111, and a return spring b114 set on the outer ring of the support rod 111.

[0032] In this embodiment, the triangular pyramid block 93 is pressed inwardly by two symmetrical rectangular columns 112 so that the triangular pyramid block 93 is released from locking the housing 1 , and the packaging plate 2 can be disassembled.

[0042] The packaging plate 2 is placed on the shell 1, and the column 91 on the fixing plate 7 is inserted into the cavity 81. The triangular pyramid block 93 on the column 91 is squeezed inward by the inner wall of the cavity 81 and is expanded in the cavity 82, thereby locking the shell 1 and the packaging plate 2.

[0043] Manually press the limit block 113 on the unlocking component 111 to push the support rod 111 to slide in the slide groove 100, driving the rectangular column 112 to squeeze the triangular cone block 93, thereby releasing the locking of the triangular cone block 93 on the shell 1 and the packaging plate 2.

[0044] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
