Line short circuit automatic protection network data transmission device

Abstract

The invention relates to the technical field of network equipment, and discloses a line short circuit automatic protection network data transmission device which comprises a shell, an electric heating block is fixedly connected to the top of the shell, symmetrical electromagnets are fixedly connected to the top of the shell, a clamping groove is formed in the top of the shell, and a clamping block is movably connected into the clamping groove. Permanent magnets are fixedly connected into the clamping blocks, and first springs are fixedly connected into the clamping grooves. According to the line short circuit automatic protection network data transmission device, through mutual cooperation of the electric heating block, the electromagnet and the permanent magnet, current in the electric heating block is increased, the electric heating block generates heat, the temperature of the electromagnet rises, the magnetic flux rate of a magnetic flux body in the electromagnet is reduced due to temperature rise, and the magnetic field intensity of the electromagnet is reduced; the clamping block moves under the action of elasticity of the first spring to release fixation of the ejector block, air pressure in the air bag is reduced, the connecting key is disconnected with a circuit under the action of elasticity of the third spring, the short-circuit protection function of the product is achieved, and damage to components is prevented.

Description

technical field [0001] The invention relates to the technical field of network equipment, in particular to a network data transmission device for automatic short circuit protection. Background technique [0002] Network transmission refers to the process of using a series of lines (optical fiber, twisted pair, etc.) to communicate according to the network transmission protocol through the adjustment and change of the circuit. The network transmission requires a medium, which has a certain impact on the data communication of the network. During the use of the transmission equipment, the overall damage of the internal circuit due to a short circuit often occurs, resulting in the loss of important data and causing losses to the user, which is not conducive to the use of the user. [0003] During the use of network data transmission equipment, it is necessary to connect the transmission equipment with the data receiving terminal, and in the process of data interaction, due to th...
