[0001] The utility model relates to the technical field of wiring structures, in particular to a wiring structure and a high-frequency and high-power power amplifier. Background Art

[0002] A high-frequency, high-power power amplifier is an electronic device used to increase the power of an input signal so that it can drive a high-power load. This amplifier is typically used in wireless communication systems, radars, radio frequency transmitters, medical equipment, and some industrial applications. When connecting cables, a wiring structure is required.

[0003] In the prior art, the traditional wiring structure usually connects the wiring terminal to the wiring board by fixing bolts. However, after long-term use, the bolts are easy to loosen, causing the cable to detach from the wiring board. The existing method is to fix the cable to the connecting plate by clamping it. Although this method can prevent the cable from detaching from the wiring board, when installing the cable, the cable will rotate, affecting the worker's operation and making it difficult to install.

[0004] Therefore, a wiring structure and a high-frequency, high-power power amplifier are needed to solve the problem that the cables of the existing wiring structure are prone to self-rotation during installation, which affects the installation operation of workers. Utility Model Content

[0028] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1

[0030] See also Figure 1-Figure 11 The utility model provides a technical solution: a wiring structure, including a power amplifier body 1, a circuit board 4 is installed on the inner wall of the power amplifier body 1, a wiring board 3 is installed on the left rear side of the circuit board 4, a fixing frame 5 is installed on the top front side of the wiring board 3, a bolt 6 is threadedly connected to the middle of the fixing frame 5, a lower pressure plate 7 is installed at the bottom end of the bolt 6, a mounting groove 8 is opened in the middle of the wiring board 3, two clamping plates 9 are arranged on the rear side of the wiring board 3, and a plurality of protrusions 10 are installed on the adjacent side of the two clamping plates 9.

[0031] First, the worker plugs the cable into the inner wall of the power amplifier body 1 and places it on the inner wall of the mounting groove 8 in the middle of the terminal block 3. Then, the bolt 6 is turned to drive the lower pressure plate 7 to move downward, and the lower pressure plate 7 is driven to rotate simultaneously, so that the lower pressure plate 7 squeezes the cable downward to make contact with the mounting groove 8. At the same time, two clamping plates 9 are provided on the rear side of the terminal block 3, and a protrusion 10 is provided on the side close to the clamping plate 9, so that the two clamping plates 9 move toward the middle of the terminal block 3 to clamp the outer side of the cable. During the clamping process, the setting of the protrusion 10 prevents the cable from rotating, thereby facilitating the workers to continue to install the cable.

[0032] Embodiment 2

[0033] On the basis of Example 1, in order to prevent the cable from rotating, two slide grooves 16 are opened on the rear side of the terminal block 3, and the inner wall of the slide groove 16 is slidably connected with a slider 15, a connecting column 14 is installed on one side of the slider 15, and a spring 17 is installed on the other side of the slider 15. The slider 15 plays a limiting role to prevent the connecting column 14 from detaching from the terminal block 3; the adjacent ends of the two connecting columns 14 are fixedly connected to the clamping plate 9, and the separated ends of the two springs 17 are installed on the inner wall of the slide groove 16.

[0034] During installation, a slider 15 slides on the inner wall of the slide groove 16 on the rear side of the terminal block 3, and a spring 17 is installed on one side of the slider 15, and a connecting column 14 is installed on the other side, so that the elastic force of the spring 17 drives the two connecting columns 14 to move toward the middle of the terminal block 3. Since the connecting columns 14 are fixedly installed with the clamping plates 9, the two clamping plates 9 are driven to move toward the middle of the terminal block 3, and then the two clamping plates 9 are driven to clamp the cables, and the protrusions 10 clamp the cables at the same time.

[0035] Embodiment 3

[0036] On the basis of the second embodiment, in order to prevent the cable from detaching from the power amplifier body 1, a threaded tube 11 is installed on the left side of the rear of the power amplifier body 1, and a threaded cover 2 is threadedly connected to the outer side of the threaded tube 11, and a rubber plug 12 is installed on the rear side of the inner wall of the threaded cover 2. A mounting hole 13 is opened in the middle of the rubber plug 12, so as to facilitate passing the cable through the inner wall of the mounting hole 13; the outer side of the rubber plug 12 is inserted into the inner wall of the threaded tube 11, and when the threaded cover 2 is threadedly connected to the outer side of the threaded tube 11, the rubber plug 12 is in a tensile deformation state.

[0037] After the cable is installed, the worker puts the threaded cover 2 on the outside of the threaded tube 11. At this time, the cable is inserted into the inner wall of the mounting hole 13. Then, the threaded cover 2 is rotated to drive the rubber plug 12 to move forward. Since the outer side of the rubber plug 12 is in contact with the inner wall of the threaded tube 11, when the threaded cover 2 moves forward, the rubber plug 12 will be stretched and deformed, and continue to move forward in contact with the inner wall of the threaded tube 11. When the threaded cover 2 and the threaded tube 11 are completely installed together, since the diameter of the rear side of the threaded tube 11 is smaller than the diameter of the front side, and the rubber plug 12 is opposite to the threaded tube 11, the threaded tube 11 and the rubber plug 12 are tightly fitted together, and the cable on the inner wall of the mounting hole 13 is also clamped to a certain extent, thereby preventing the cable from detaching from the power amplifier body 1.

[0038] Embodiment 4

[0039] Based on the third embodiment, a high-frequency and high-power power amplifier is proposed, including a wiring structure.

[0040] During actual use, the worker first plugs the cable into the inner wall of the power amplifier body 1 and places it on the inner wall of the mounting groove 8 in the middle of the terminal block 3. Then, the bolt 6 is turned to drive the lower pressure plate 7 to move downward, and the lower pressure plate 7 is simultaneously driven to rotate, so that the lower pressure plate 7 squeezes the cable downward to make contact with the mounting groove 8. At the same time, two clamping plates 9 are provided on the rear side of the terminal block 3, and a protrusion 10 is provided on the side close to the clamping plate 9, so that the two clamping plates 9 move toward the middle of the terminal block 3 to clamp the outer side of the cable. During the clamping process, the protrusion 10 is provided to prevent the cable from rotating, thereby facilitating the workers to continue to install the cable.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
