Description

TECHNICAL FIELD

[0001] The utility model relates to communication cable technical field, concretely is communication cable joint protection device. BACKGROUND

[0002] Communication cable is an indispensable part of modern communication system, which is responsible for transmitting telecommunication signals and ensuring the rapid and accurate transmission of information. With the development of society and the continuous progress of communication technology, the demand for communication cable is increasing. During the process of cable erection, the situation of insufficient cable length often occurs, at which time the cable joint needs to be connected. However, in the existing technology, the cable joint is exposed to the external environment for a long time and is easily affected by external factors such as rain, dust, and oxidation. These factors can cause damage to the cable joint, resulting in cable disconnection and affecting the normal operation of the communication system.

[0003] The patent with publication number CN214044143U discloses a communication engineering communication cable connection wire head protection device, which includes an upper protection cover, a telescopic rod, a cable hole, and a drying box. The bottom of the upper protection cover is provided with a lower protection cover. The telescopic rod is fixedly installed at the bottom of the upper protection cover and the top of the lower protection cover. One end of the telescopic rod is fixedly installed with a clamping assembly. In this application, the wire joint can be easily fixed and protected, preventing damage to the wire joint caused by exposure to the outside. The connection of the cable is fixed to prevent the cable from disconnecting, improving the use effect of the communication cable. The connection of the cable is dehumidified to prevent the cable from being damaged by moisture and to prolong the service life of the cable.

[0004] The above-mentioned prior art fixes the upper protection cover and the lower protection cover by buckles and slots, and fixes the cable joint by the telescopic rod and the clamping assembly. However, in actual application, the stability of the device is still insufficient. Due to the reaction force generated by the telescopic rod when pressing the cable joint, the upper protection cover and the lower protection cover connected by buckles and slots are easily pushed open, resulting in failure of the protection device. In addition, the work of the telescopic rod, wireless module, and controller requires power supply, which not only increases the initial cost of cable joint protection but also increases the difficulty of later maintenance. These problems limit the application range of the existing technology. In view of this, we propose a communication cable joint protection device. UTILITY MODEL CONTENTS
