Fixing device and shielding assembly

Abstract

The invention provides a fixing device and a shielding assembly, and the fixing device comprises an attaching bottom and at least two elastic arms; the attaching bottom is used for being attached to a plate and is provided with two opposite sides, each elastic arm is provided with a fixing part, and in the process that a to-be-fixed part is inserted towards the attaching bottom, the elastic arms are integrally stressed to deform; and after the to-be-fixed part is inserted in place, the elastic arms integrally rebound, the fixing part of at least one elastic arm abuts against the to-be-fixed part under the action of resilience force, and the fixing part of at least one elastic arm clamps and locks the to-be-fixed part. According to the invention, assembly and alignment are easier, an obvious feedback sense is provided, an operator can know that assembly and positioning are completed, and visual inspection is not needed; moreover, while correct positioning is carried out, the elastic arm is utilized to continuously interfere and apply pressure to the to-be-fixed part, and the requirement of conduction can be met at the same time.

[0002] Existing electronic equipment, taking notebook computers as an example, in the assembly of the motherboard of the notebook computer, that is, the Printed Circuit Board (PCB), due to the requirement of radio frequency (Radio Frequency, referred to as RF), it is necessary to double the rate Synchronous Dynamic Random Access Memory (Double Data Rate SDRAM, referred to as DDR) and Random Access Memory (Random Access Memory, referred to as RAM) are shielded to avoid signal interference. Stainless steel) cover and use Surface Mounted Technology (SMT) shrapnel as the assembly and fixing device, but the existing commonly used SMT shrapnel requires precise alignment during assembly operations. If the assembly is misplaced or the height is not high Pressed to the position, due to lack of sufficient feedback, it is difficult to detect assembly errors visually, resulting in the failure of the shielding function or the problem of shielding interference with other parts.
