Embodiment Construction

[0053] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0054] In order to improve the sensitivity and anti-interference performance of electronic equipment, especially portable mobile electronic equipment, it is usually necessary to use shielding covers to shield sensitive signals or interference sources. The shielding case can shield the influence of external electromagnetic waves on the circuit in the shielding case, and can also prevent the electromagnetic waves generated inside the shielding case from radiating outward.

[0055] Taking a mobile phone as an example, the circuit board in the mobile phone is usually provided with a shielding cover, and the shielding cover covers the components on the circuit board inside, which can prevent the components inside the shielding cover from causing interference to other components in the mo...

Abstract

The invention provides a shielding cover, a circuit board assembly and electronic equipment. The shielding cover comprises a cover body, wherein the cover body and a circuit board jointly enclose a shielding region, and at least part of components on the circuit board are covered in the shielding region. The components located in the cover body comprise a first device, the first device has a step face facing the cover body, a reinforcing part is arranged in the region, corresponding to the step face of the first device, of the cover body, at least part of the structure of the reinforcing part is located in the region, right facing the step face, of the cover body, the space formed above the step face of the first device is utilized, the reinforcing part is additionally arranged to increase the strength of the cover body, the surrounding region of the part corresponding to the step surface on the cover body is prevented from collapsing, and the stability and reliability of the shielding cover are improved. Moreover, the distance between the first device and the adjacent components is kept unchanged or the increase of the distance between the first device and the adjacent component is reduced, so that the circuit board can keep a densely arranged layout structure, the component layout area of the circuit board is saved, and the space utilization rate of the circuit board is improved.

Description

technical field [0001] The present application relates to the technical field of electromagnetic shielding, in particular to a shielding cover, a circuit board assembly and electronic equipment. Background technique [0002] Currently, terminal devices such as mobile phones, tablet computers, notebook computers, and personal digital assistants (Personal Digital Assistant, PDA) are generally provided with shielding covers for shielding electromagnetic wave signals. [0003] Taking the circuit board as an example, the shielding cover erected on the circuit board includes a support frame and a cover body. The support frame is fixed on the circuit board. The components on the circuit board are located in the area surrounded by the support frame. The cover body is connected to the support frame. Externally, the enclosure completely wraps the components inside to form a complete shielding structure. [0004] However, in areas where components are densely packed and the space is c...
