Abstract: An electrical connector with extension terminals includes an insulating housing, a movable terminal, a spring and a conductive reed terminal. The insulating housing has terminal axial holes each having a ridge. The insulating housing has reed sockets arranged around and communicated with the terminal axial holes. The movable terminal accommodates therein a spring. The movable terminal has a groove. The movable terminal is such inserted into the terminal axial hole of the insulating housing that the groove fittingly receives the ridge, thereby limiting the movable terminal to move in the terminal axial hole but preventing the movable terminal from leaving from and rotating in the terminal axial hole. The conductive reed terminal has inserts and a weld leg. The insert has a reed. When the insert is inserted into the reed socket, the reed abuts against the movable terminal, thereby establishing conductivity therebetween.

Abstract: An improved heat-dissipation structure for a matrix LED lamp is disclosed. The heat-dissipation structure is a plate-shaped metal hood configured to hold an LED matrix module for heat dissipation so as to maintain the entire matrix LED lamp cool. The heat-dissipation structure is a plate-shaped metal shell having a plurality of threaded holes allowing the LED matrix module to be fixed thereto. In virtue of the tight contact between the bottom of the LED matrix module and the plate-shaped metal hood, heat generated by the LED matrix module can be quickly absorbed and dissipated by the plate-shaped metal hood, so as to prevent the LED matrix module from premature aging, thereby enlightening the service life of the LED matrix module.
