Problems solved by technology
[0003] When the signal amplifier is working, it is necessary to ensure the reliability of the line and the stability of the signal. In order to make the signal amplifier work stably for a long time, the signal amplifier must be effectively protected. Although the existing signal amplifier has a protection device, it cannot This protection device only wraps the signal amplifier through a shell, and the protection effect is very limited. When there is an external impact on the device, it cannot effectively protect the trunk amplifier. Too much rain falls on the protection device. The existing device is inconvenient to drain rainwater, and it is very troublesome to disassemble the signal amplifier when it needs to be repaired. In addition, because this kind of protection device is tightly sealed, the internal ventilation and heat dissipation conditions are poor, which cannot make the main line amplifier play the best role. For effective signal transmission, the existing devices usually do not have the function of raising and lowering the trunk amplifier, which makes it inconvenient to adjust the height of the device when the trunk amplifier is placed in a special place. Therefore, we propose a trunk amplifier for protective device

The invention discloses a protection device for a trunk amplifier, which relates to the technical field of electronic components, in particular to a protection device for a trunk amplifier, which includes a storage box, and ventilation pipes are fixedly installed on both sides and the bottom inside the storage box. And both sides of the ventilation duct are fixedly installed with ventilation ducts. The protective device for the trunk amplifier can protect the device to a certain extent through the outer protective plate arranged on the top of the protective cover, and the evenly distributed drainage grooves arranged on the outer surface of the outer protective plate can make rainwater fall on the outer protective plate. , it is more convenient to export rainwater, and the outer protective plate is designed in an arc shape to make it easier for rainwater to slide down when it hits the outer protective plate, which solves the problem of exporting rainwater when the existing device is not put down. The waterproof setting of the outer surface improves the rainproof function of the device.
Description
technical field [0001] The invention relates to the technical field of electronic components, in particular to a protection device for a trunk amplifier. Background technique [0002] Trunk amplifier, referred to as dry amplifier, is a signal amplification device when the power becomes low and cannot meet the coverage requirements. When the power of the signal source equipment is difficult to meet the coverage requirements, the device can amplify the power of the signal source (usually a microcell) to Covering more areas, trunk amplifiers are generally used to cooperate with microcellular base stations or repeaters to solve indoor signal blind spots. It adopts dual-port full-duplex design, built-in power supply, easy installation, high reliability, and digital and analog systems are compatible. , if used as a distributed indoor coverage system, they can also be used as line relay amplification or extension amplification, covering an area of up to tens of thousands of squar...
