Abstract
The invention relates to a low-melting-point metal cable connection terminal which is characterized in that the appearance of the terminal is a sealed cylinder, and the two ends of the terminal are provided with small holes for cables to insert. The terminal is composed of a cavity filled with low-melting-point metal, a pair of silicon sealing rings, a pair of metal elastic pieces and a pair of one-way clamps. The low-melting-point metal filled into the cavity of the terminal is in the liquid state at normal temperature, and is a connection material for achieving conducting connection of two cables. The silicon sealing rings are arranged at the two ends of the low-melting-point metal cavity and used for sealing the low-melting-point metal so as to prevent leakage. The metal elastic pieces are attached to the silicon sealing rings to prevent loosening of the silicon sealing rings so as to further guarantee sealing performance of the low-melting-point metal. The one-way clamps are arranged at the two ends of the terminal so that cables which are inserted in the two ends can not fall outwards, a cable fixing effect and a cable fall-preventing effect are achieved. The low-melting point metal cable connection terminal is simple in structure, convenient to operate, friendly to the environment, safe, reliable, and capable of being widely applied to the field of cable connecting engineering like rail traffic and information communication, and energy is saved.
