At the same time, people are increasingly demanding the appearance of electronic devices. The housing of the electronic device is generally made of metal or plastic, and is widely used in electronic devices due to its high strength and good electromagnetic shielding effect. [0003] When a metal casing is used, in order to prevent the electromagnetic shielding from affecting signal transmission and reception, the antenna cover portion of the electronic device casing is usually made of plastic, and then the plastic antenna cover is fixed by hooking or riveting. It can be on the metal casing. However, the manner in which the hooks are engaged and riveted is prone to defects such as large gaps and looseness, which affect the strength and appearance of the product. As electronic products become lighter, thinner, shorter, and smaller, the thickness of electronic device housings will become thinner and thinner. When the thickness of the electronic device housing is reduced to a certain extent, the hooks are used. And the way of riveting is prone to break stress and affect the strength of the product. The shortcomings and limitations of the above-mentioned combination methods are accompanied by the trend of thinning electronic products.
