[0013] The alarm component includes a battery, a temperature switch, a resistor and an indicator light connected in sequence, which is used to monitor whether the temperature of the current terminal is abnormal. If the temperature rise reaches a preset safety value, the indicator light will alarm.

[0014] Furthermore, the outer shell includes a protective cover and an insulating base. The main conductive block, the auxiliary conductive block, and two wire crimping assemblies are all arranged on the insulating base. A buckle is arranged on each side of the insulating base. A socket is arranged at the corresponding position of the protective cover. The insulating base is clamped in the protective cover through the buckle.

[0015] Furthermore, the main conductive block includes a bottom plate and two oppositely arranged conductive plates, one end of the bottom plate is connected to the bottom of the same end of the two conductive plates, the other end of the bottom plate extends to the outside of the two conductive plates, and the tops of the two conductive plates are connected by a connecting bridge.

[0016] Furthermore, the structure of the auxiliary conductive block is the same as that of the main conductive block, and the length of the conductive plate of the auxiliary conductive block is shorter than the length of the conductive plate of the main conductive block.

[0017] Furthermore, the conductive slider includes two vertically symmetrical T-blocks, the longitudinal sections of the two T-blocks are arranged opposite to each other and connected by bolts, the conductive plate is arranged between the two T-blocks, and the inner wall of the conductive plate is close to the longitudinal sections of the two T-blocks.

[0018] Furthermore, the wire crimping assembly includes a locking screw and a wire crimping frame. A wiring window is provided on the protective cover at a position corresponding to the wire crimping frame for inserting the wire. The locking screw thread passes through the top of the wire crimping frame for making the bottom plate contact the wire.

[0019] Furthermore, a mounting groove is provided on a side of the protective cover away from the insulating substrate, and the alarm component is installed in the mounting groove.

[0020] The beneficial effects of the utility model are: the current terminal has a compact structure, a simple appearance, and is easy to install or disassemble; an alarm component is set to monitor whether the temperature of the current terminal is abnormal. If the temperature rise reaches a preset safety value, the indicator light alarm is started, which is convenient for monitoring and managing the temperature rise, thereby improving the safety and reliability of the current terminal during use.
