Description

Plastic panel

The invention relates to a plastic panel.

Generally speaking, in the assembly process of electronic products, the most common way to fix the two plastic parts is to use an insulating nut with a grain on the outer surface in the form of heat staking. The copper crucible is buried directly into the hole in one of the plastic parts, or the copper crucible is directly buried in the process of injection molding of the plastic part. By forming a grain on the outer surface of the copper truss column, the bond between the hole and the column can be increased. Then, the screw is inserted through the through hole of the other plastic member to lock the copper post, so that the two plastic pieces can be locked together.

However, when using the aforementioned copper crucible embedded or buried in hot melt, the thickness of the coated flesh (i.e., the wall thickness of the column) has a certain specification. If the meat is not thick enough, it will not be able to cover and hold the copper truss column, which will cause the copper truss column to loosen when the screw is locked (due to insufficient tensile and torsional resistance), and it is impossible to lock the two plastic parts.

This is true for a single column. If it is used in many common electronic products, it often uses many different types of copper columns. Correspondingly there are many holes in the design. In the case that the models of the copper trusses used are not uniform, the performance of the differently designed pylons cannot fully meet the customer's recommended tensile and torsion specifications.

The invention provides a plastic panel comprising a plate body and a plurality of holes. The plate body has a plate thickness. The column of holes is connected to the plate body. Each column has an opening and a receiving hole. The receiving hole is formed by recessing the opening inward. The accommodating holes are adapted to be fitted to the copper trusses of the type #6-32. Each column has a wall thickness. The wall thickness is equal to or greater than 1.5 mm, and the plate thickness is 1.6 to 2 times the wall thickness.

In an embodiment of the invention, each of the holes has an outer diameter and an inner diameter. The outer diameter is equal to or greater than 8 mm. The inner diameter is equal to or less than 5 mm.

In an embodiment of the invention, each of the holes has a wall height with respect to the plate body. The wall height is greater than the length of the copper truss in the direction of its axis.

In an embodiment of the invention, the opening has a lead angle. The lead angle has a horizontal width in the horizontal direction of the parallel plate body and a vertical height in the vertical direction of the vertical plate body. The horizontal width is equal to the vertical height.

In an embodiment of the invention, the horizontal width and the vertical height are substantially 0.3 mm.

In an embodiment of the invention, the inner wall of the accommodating hole has a counterbore portion. The counterbore portion is formed by recessing inwardly from the opening.

In an embodiment of the invention, the counterbore portion has a horizontal width in a horizontal direction parallel to the plate body, and is vertical in the vertical plate body. There is a vertical depth in the direction. The horizontal width is substantially 5.64 mm and the vertical depth is substantially 0.3 mm.

In an embodiment of the invention, the wall thickness is further equal to or greater than 1.8 mm.

In an embodiment of the invention, each of the holes has an outer diameter and an inner diameter. The outer diameter is equal to or greater than 8.4 mm. The inner diameter is equal to or less than 4.8 mm.

In an embodiment of the invention, each of the holes has a wall height with respect to the plate body. The wall height is equal to or greater than 4.2 mm.

In summary, the plastic columns included in the plastic panel of the present invention are specially designed to be fitted with the copper cymbal of the type #6-32, so that the complexity of the plastic panel can be reduced, and the burial is performed. The performance of the hole column can also be fully grasped. Moreover, in order to enable the above-mentioned copper truss column to expand the use range to the processing operation of the hot melt embedding, the plastic panel of the present invention proposes a different hole column design to match. It can be seen that the plastic panel of the invention can be effectively applied to the processing process of the buried incident process and the hot melt embedding process, and comprehensively meets the specifications of the tensile force and the torsion recommended by the customer.
