Wiring terminal

The invention relates to the field of strong current wiring devices, in particular to a wiring terminal which comprises an installation part and a wiring part connected with the installation part, an installation hole is formed in the installation part, and a concave channel is formed in the surface of the wiring part. The channel is provided with a light absorbing and emitting part connected with the wiring part; the light-absorbing and light-emitting part is connected with the wiring part through a heat insulation part and is communicated with the outside through the channel; a thermal transparent material layer for shielding the light-absorbing and light-emitting part is arranged on the light-absorbing and light-emitting part, and the thermal transparent material layer is connected with the wiring terminal. The situation that an existing wiring terminal passively depends on warning and protection generated by the outside or other related parts is changed, warning is generated along with temperature changes
