Description

Technical Field

[0001] The utility model belongs to the technical field of switches, and in particular relates to a PCBA support structure based on a 1U switch. Background Art

[0002] In the server industry, the number of optical ports is increasing, and the PCBA layout is becoming increasingly compact and complex, resulting in very limited space for positioning support. Conventional support using SMT NUTs or screw columns occupies a large area and also increases costs. Existing optical port configurations are increasing, and their products have high power consumption, more heat dissipation components, and increased PCBA weight. Increasing the PCBA thickness will also increase product costs accordingly. In addition, during the assembly process, the use of conventional supports will cause varying degrees of deformation of the PCBA, affecting the difficulty of assembly and posing a high risk of short circuits. To avoid this risk, a large area of ​​insulation sheets needs to be added, which increases costs to a certain extent. The cost increases of various factors lead to insufficient product competitiveness. Utility Model Content

[0003] This utility model aims to address the shortcomings of existing PCBA positioning and support technologies, such as large footprint, high cost, and easy PCBA deformation during assembly. By proposing a 1U switch PCBA support structure, this 1U switch PCBA support structure can effectively reduce PCBA deformation and overall cost.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A PCBA support structure based on a 1U switch is designed, including a casing and an optical port fixing frame. A PCBA board is fixed in the casing, and the optical cage on the PCBA board is plugged into the optical port fixing frame. A first plug-in board and a second plug-in board for plugging and fixing are respectively provided on the docking interface between the casing and the optical port fixing frame. The first plug-in board is located below the optical cage. A supporting boss for supporting and fixing the PCBA board is provided on the first plug-in board along the length direction. The supporting boss is formed on the first plug-in board by stamping.

[0006] Furthermore, the first plug-in board is in an elongated strip shape, and each first plug-in board is provided with at least one supporting boss.

[0007] Furthermore, the supporting boss is in the shape of an arch bridge ball.

[0008] The utility model proposes a 1U switch PCBA support structure with the following beneficial effects: the utility model effectively improves PCBA deformation and overall cost reduction without affecting the product appearance, which can effectively improve the price competitiveness of the product. Specifically:

[0009] (1) The utility model can reduce the number of SMT NUT or riveted iron studs.

[0010] (2) The utility model provides a supporting boss, which occupies a small area and effectively saves the layout area of ​​the PCBA.

[0011] (3) The utility model has a good supporting effect on the PCBA board under the light cage, which can prevent the deformation of the PCBA board, reduce the risk of short circuit of the PCBA board, and reduce the material cost and manual pasting of the insulation sheet.
