Description

Technical Field

[0001] This utility model relates to HDI circuit boards, and in particular to an HDI circuit board structure with an adaptive positioning structure. Background Technology

[0002] HDI (High-Density Interconnect) circuit boards are high-density interconnect circuit boards that achieve high-density circuit distribution through the use of micro-blind vias and buried vias. HDI circuit boards offer advantages such as thinness, high circuit density, facilitating the application of advanced packaging technologies, and superior electrical characteristics and signal transmission, making them widely used in various electrical products. However, because the mounting holes in the product casing are fixed after molding, they cannot be freely adjusted or require re-drilling to accommodate the HDI circuit board. Therefore, when subsequently installing the HDI circuit board within a casing, it may not fit the current product casing for proper installation and fixation, resulting in poor installation compatibility.

[0003] Therefore, existing HDI circuit boards need further improvement. Utility Model Content

[0004] The purpose of this invention is to provide an HDI circuit board structure with an adaptive positioning structure, which allows for adjustment of mounting holes at any position within the adjustment range, aligning the positions of different mounting holes on the housing within the adaptation range, thereby improving the adaptability of the installation.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] An HDI circuit board structure with an adaptive positioning structure includes an HDI circuit board, on which a plurality of swing connecting rods are provided, and on each swing connecting rod a linear movable screw sleeve is provided. A fastening screw sleeve structure for restricting the movement of the linear movable screw sleeve is provided between the linear movable screw sleeve and the swing connecting rod, and an elastic structure for pressing against the fastening screw sleeve structure is provided between the fastening screw sleeve structure and the linear movable screw sleeve.

[0007] Furthermore, there are four swing connecting rods, which are respectively located at the four corners of the HDI circuit board.

[0008] Furthermore, the swing connecting rod includes an opening at the corner of the HDI circuit board, a fixed bushing is embedded in the opening, an inner rotating sleeve is rotatably disposed inside the fixed bushing, and a swing rod is disposed at the lower end of the inner rotating sleeve.

[0009] Furthermore, the linear movable screw sleeve includes a linear straight groove disposed on the swing rod, and limiting grooves are provided on both sides of the inner wall of the linear straight groove. A positioning screw sleeve is movably disposed in the linear straight groove, and a limiting ring is provided on the outer circumference of the positioning screw sleeve, which can be locked in the limiting groove.

[0010] Furthermore, the fastening screw sleeve structure includes an external thread provided on the positioning screw sleeve, and a locking nut that can press against the lower surface of the swing rod is connected to the external thread.

[0011] Furthermore, the elastic structure includes a spring boss disposed on the lower end face of the positioning screw sleeve, and a compression spring for pressing the locking nut is disposed between the spring boss and the locking nut.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention addresses the shortcomings of existing HDI circuit board structures. Through its structural design, it offers the following advantages: four swinging rods adjust the direction and angle of the screw sleeve, aligning it with the positioning holes on the outer casing. The screw sleeve is then moved to the corresponding positioning hole position for alignment, completing positioning adjustments and installation at different locations. Furthermore, the inclusion of a locking nut and a compression elastic structure enhances the positional stability of the screw sleeve, significantly improving its compatibility with different casing models.
