Description

Technical Field

[0001] This utility model relates to the field of shielding cover installation technology, and more specifically, to a detachable shielding cover assembly fixture. Background Technology

[0002] The shielding cover consists of legs and a cover body, with the legs and cover body being movably connected. The cover body is spherical to prevent electromagnetic interference and can shield components and LCMs on PCBs. It has wide applications in mobile phones and automobiles, preventing functional problems of core components such as MCUs and crystal oscillators on PCBAs. The shielding cover is usually installed using conductive adhesive, which has electromagnetic shielding and conductive connection functions, improving shielding effectiveness and lifespan. Specifically, the conductive adhesive can create connectivity within the shielding cover, enhancing the shielding effect, and can connect different components, improving the reliability of the circuit board. When inspecting the core components under the shielding cover, the shielding cover must be disassembled to access the internal components for repair.

[0003] However, the current method of installing the shielding cover using conductive adhesive results in a high strength of the shielding cover. However, when disassembling the shielding cover, it is easy to cause deformation and damage, which makes it difficult to quickly install and remove the shielding cover and affects the convenience of workers to inspect and maintain the core components under the shielding cover. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a detachable shielding cover assembly fixture. The technical problem to be solved by the present invention is: how to increase the stability of the installation of the shielding cover body and the convenience of disassembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detachable shielding cover assembly fixture, including a chip mounting plate, a shielding cover mounting base at its upper end, a shielding cover limiting block at the upper side of the inner end face of the shielding cover mounting base, a limiting protrusion at the upper side of the inner end face of the shielding cover limiting block, and a shielding cover body at the outer side of the upper end of the chip mounting plate.

[0006] The upper end face of the shielding cover body is provided with a circular hole, and the lower side of the outer end face of the shielding cover body is provided with a limiting mounting plate. The end face of the limiting mounting plate is provided with an adapter slot, and the end face of the limiting mounting plate is provided with a partition groove on the side near the adapter slot.

[0007] In a preferred embodiment, the shield mounting base is connected to the chip mounting plate by an adhesive, and the shield limiting blocks are provided in multiple quantities and arranged in an array on both sides of the vertical central axis of the shield mounting base in the top view direction.

[0008] In a preferred embodiment, the number of limiting protrusions is provided in multiples, and they are arranged in an array on both sides of the vertical central axis in the top view direction of the shielding cover limiting block.

[0009] In a preferred embodiment, the shielding cover body is a stainless steel component, and the number of circular holes is multiple, arranged in an array on both sides of the vertical central axis of the shielding cover body in the top view direction.

[0010] In a preferred embodiment, the number of limiting mounting plates is multiple, and they are arranged in an array on both sides of the vertical central axis in the top view of the shield body, and the limiting mounting plates have strong elasticity.

[0011] In a preferred embodiment, there are multiple partition slots and adapter slots, and they are arranged in an array on both sides of the vertical central axis in the main view direction of the limiting mounting plate.

[0012] The outer end face of the limiting mounting plate in the top view direction is adapted to the inner end face of the limiting protrusion in the top view direction, and the outer end face of the limiting protrusion is adapted to the inner end face of the matching slot by snap-fit.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In actual use, the corresponding arrangement of the limiting protrusion, the limiting mounting plate, and the adapter slot allows for easy engagement and fixation of the limiting protrusion and the adapter slot. This facilitates the engagement of the shielding cover body onto the inner side of the shielding cover limiting block, thereby simplifying the installation and fixation of the shielding cover body. It also effectively increases the ease of installation and disassembly of the shielding cover body. Furthermore, with the inner end face of the shielding cover limiting block and the outer end face of the limiting mounting plate in a compatible manner, the stability of the shielding cover body during installation is effectively increased, preventing loosening of the shielding cover body after installation.
