Abstract

The invention provides a low-melting metal cable connection device and a use method thereof. The use method comprises the following steps: encapsulating the low-melting metal in a heat-conducting connector, inserting the conductive core of the to-be-connected cable into the low-melting metal, heating the heat-conducting connector to enable the low-melting metal to completely contact with the conductive core of the cable; guaranteeing the connection stability between the cable cores by using the conductivity of the low-melting metal, thereby guaranteeing the safe and stable running of the cable connecting point under the situations that the sustained cable works in normal and works overload within short time; and meanwhile, the soldering flux is further used for effectively removing an oxide film with bad conductivity on the surface of the cable core; the contact resistance of the cable is reduced, and the power transmission efficiency of the cable is improved.

Description

technical field [0001] The present invention relates to the technical field of cable connection, and more specifically, to a low-melting-point metal cable connection device, its use method, and connection structure. Background technique [0002] The cable is usually twisted by several or several groups of wires (at least two in each group), similar to a rope cable, each group of wires is insulated from each other, and is often twisted around a center, and the entire outer Has a highly insulating covering. The cable has the characteristics of internal energization and external insulation, and is used to connect circuits, electrical appliances, etc. However, the length of the cable is limited. When the length of the cable cannot meet the requirements of use, it is necessary to effectively connect the two cables to extend the transmission distance of the cable. [0003] Cable connection is an important part of the construction of communication lines. Due to mechanical damage,...
