Description

Technical Field

[0001] The utility model relates to the technical field of PTFE high-frequency plates, in particular to a signal-enhanced high-frequency PTFE ultra-thin plate. Background Art

[0002] High-frequency boards have important applications in the field of 5G communications. High-frequency transmission technology is one of the key technologies for 5G wireless communications. It can increase the availability of frequency band resources to meet the technical requirements of network development. To achieve high-frequency transmission, functional materials with low dielectric constant and low dielectric loss must be used, and PTFE is the representative of such low dielectric materials.

[0003] Signal enhanced high frequency PTFE ultra-thin board is a high frequency board using polytetrafluoroethylene (PTFE) as the base material. In order to improve the rigidity of the base material and reduce its thermal expansion, a large amount of inorganic substances such as silicon dioxide SiO2 or glass cloth are usually added as reinforcing fillers.

[0004] The signal enhancement function of the signal-enhanced high-frequency PTFE ultra-thin sheet is achieved based on some special properties of the PTFE material. These properties include its low dielectric loss and low dielectric constant. First, low dielectric loss means that the material itself generates less heat during signal transmission. This is very important for maintaining the stability of signal transmission, because overheating can cause signal attenuation and, in some cases, may cause damage to the equipment. Secondly, the low dielectric constant can make the signal faster during transmission. Electromagnetic waves propagate slowly in a medium with a high dielectric constant, and quickly in a medium with a low dielectric constant. Therefore, the PTFE ultra-thin sheet can ensure the transmission speed of high-frequency signals.

[0005] Signal-enhanced high-frequency PTFE ultra-thin plates have attracted widespread attention due to their superior performance. However, existing signal-enhanced high-frequency PTFE ultra-thin plates still have some obvious problems in practical applications. Specifically, the current signal-enhanced high-frequency PTFE ultra-thin plates need to be fixed with multiple bolts during installation, which increases their complexity and time cost to a certain extent. More importantly, when these plates need to be repaired, the staff needs to remove and install multiple bolts. This process not only wastes time and effort, but may also have a negative impact on the integrity and stability of the plates.

[0006] Especially in the case of repeated maintenance, the thread grooves on the bolts and the shell may be stripped, making it difficult for the signal-enhanced high-frequency PTFE ultra-thin plate to remain in a stable position, which will greatly reduce its performance and may cause system instability. Therefore, the existing signal-enhanced high-frequency PTFE ultra-thin plate fixing method can no longer meet the needs of efficient and fast installation and maintenance. In view of this, we propose a signal-enhanced high-frequency PTFE ultra-thin plate. Utility Model Content

[0028] The signal-enhanced high-frequency PTFE ultra-thin plate comprises four rectangular solid blocks 1 arranged in a matrix, a strip cross bar 2 is provided between two adjacent rectangular solid blocks 1 on the left and right, and a strip longitudinal bar 3 is provided between two adjacent rectangular solid blocks 1 on the front and back, and the four rectangular solid blocks 1 are connected together by two strip cross bars 2 and two strip longitudinal bars 3, thereby forming a base for installing the signal-enhanced high-frequency PTFE ultra-thin plate;

[0029] The middle parts of the opposite sides of the two strip longitudinal bars 3 are slidably connected with rectangular moving bars 6, and the opposite ends of the two rectangular moving bars 6 respectively penetrate the opposite sides of the two strip longitudinal bars 3.

The two L-shaped blocks 7 can be pulled outward, and the springs 8 are compressed, so that the L-shaped blocks 7 exert a certain pressure on the high-frequency board body 4;

[0030] The tops of the four rectangular solid blocks 1 are commonly connected to a high-frequency board body 4. U-shaped slots 41 are provided in the middle of the left and right sides of the high-frequency board body 4. Two L-shaped blocks 7 are respectively engaged with the two U-shaped slots 41. Under the action of the two L-shaped blocks 7, the position of the high-frequency board body 4 is fixed.

[0031] In this embodiment, mounting seats 20 are provided on the opposite sides of the two strip cross bars 2 and near the left and right ends. The top of the mounting seats 20 is provided with mounting holes for bolts to pass through, so that the four mounting seats 20 can be installed in the shell, thereby fixing the positions of the rectangular solid block 1, the strip cross bar 2 and the strip longitudinal bar 3.
