The material of described cable splice is red copper.

Double end screw rod is made of copper, and heat is delivered on temperature probe by cable splice, and temperature probe temperature information is passed by optical fiber, it is achieved that detect in real time, transmits information by optical fiber, greatly reduces error rate and loss rate that data are transmitted. Owing to temperature probe is positioned at cable splice inside, the material of cable splice is red copper, and the insulation layer epidermis measured in prior art outside cable plug head, and the temperature data obtained is more accurate, more truly. The tail end of described double end screw rod refers to the one end near stifled head, and described double end screw rod is front end away from one end of stifled head, described double end screw rod tie cable.

Further, described stifled portion end to end is stamped to protect and emits, described electrical verification nut be positioned at described in protect and emit inner side.

Further, described double end screw rod front end is connected with switching cabinet sleeve pipe.

Further, described switch sleeve tube-surface is nested with front plug, and this front plug and rear slotting main body closely cooperate.

Further, temperature probe adopts stupalith. Temperature probe is stupalith, and temperature-sensitive performance is good, and cost is low, temperature-measuring optical fiber itself is silica glass, insulation, and corrosion resistance nature is good, problems such as can bearing the high temperature of more than 1000 degree, it is possible to well infiltrated with epoxy resin, there will not be bubble, rupture and come off.

Useful effect: owing to temperature probe is positioned at cable splice inside, the material of cable splice is red copper, and for the insulation layer epidermis measured in prior art outside cable plug head, the temperature data obtained is more accurate, more truly. Temperature probe is stupalith, and temperature-sensitive performance is good, and cost is low.
