Moisture absorption expansion type connector for weak current intellectualized place

Abstract

The invention relates to the technical field of weak current intellectualization, and discloses a moisture absorption expansion type connector for a weak current intellectualized place, which comprises a shell, a connecting rod is movably connected in the shell, a clamping block is fixedly connected to the surface of the connecting rod, and a clamping groove is movably connected to one end, away from the connecting rod, of the clamping block. A push rod is hinged to the surface of the connecting rod and is located on the right side of the clamping block. The end, away from the connecting rod, of the push rod is fixedly connected with an electric connecting plate, and the interior of the electric connecting plate is fixedly connected with an airflow channel. When a fire disaster occurs, a water sprayer sprays water to enable air around a weak current intelligent box to become moist, the moist air enters the airflow channel in the shell to be absorbed by a filling bag, and the filling bag pushes a damping block to move in the direction away from an airflow channel after absorbing the moist air, pushes the damping block out of a flow blocking opening and is clamped with a connecting opening in the weak current box. An insulating block is arranged at the clamping part, so that the effects of automatically cutting off power and blocking the connecting port when a fire disaster occurs and water is sprayed are achieved.

Description

technical field [0001] The invention relates to the technical field of weak current intelligence, in particular to a moisture-absorbing expansion connector used in weak current intelligent places. Background technique [0002] Weak current generally refers to DC circuits, and household appliances such as telephones, computers, TV signal inputs, audio equipment and other household appliances are all weak current electrical equipment. [0003] With the rapid development of the national economy, the construction of the weak current intelligent system in the park is increasing day by day, but the protection measures for the weak current intelligent box have not been developed together, especially in the event of a fire, the traditional protection measure is to install a fire alarm Sensors and sprinkler sensors to mitigate fire damage to smart boxes. [0004] It is well known that the weak current smart box is a device that makes the weak current equipment tend to be intelligent...

AI Technical Summary

Problems solved by technology

[0004] It is well known that the weak current smart box is a device that makes the weak current equipment tend to be intelligent. It has electrical properties when it is powered on. Spraying the smart box, the sprayed water will not only damage the smart box, but also splash into the socket and other connectors, causing the entire circuit to be paralyzed, increasing the risk of personal injury and increasing maintenance costs. A moisture-absorbing expansion connector for weak current intelligent places came into being
