| 20090237198 | SAFETY POWER DISCONNECTION TERMINAL APPARATUS WITH LIGHT INDICATION - The present invention discloses a safety power disconnection terminal apparatus with light indication that includes: a housing, having two inspecting openings and a light transmitting portion provided at the top of the housing, and an opening provided at the bottom of the housing; a terminal pin installed in the housing, having two parallel conducting plates, and a fuse connected in between the two conducting plates. Terminal portions are provided at upper ends of the two conducting plates, and are exposed through the two inspecting openings, and L-shaped stands are provided at inner sides of the upper ends of the two conducting plates. A LED module has two LEDs serially connected with at least one voltage divided resistor that are mounted directly onto a surface of PCB. | 09-24-2009 |
| 20100033294 | FUSE SEAT WITH PROMPTING FUNCTION - A fuse seat with prompting function is to provide a fuse plugged therein conductively. The fuse seat includes an insulating body, two electricity-conducting pieces, two electric wires and a light-emitting unit. The insulating body is arranged an accommodating space and is configured a through trough. Two electricity-conducting pieces are respectively arranged in the accommodating space. The fuse is plugged into the accommodating space and is connected conductively to the electricity-conducting pieces. One side of each electric wire is respectively connected to the electricity-conducting pieces electrically and is extended out of the insulating body. The light-emitting unit is embedded fixedly in the insulating body, accommodated in the through trough and connected electrically to the electricity-conducting pieces respectively. When an overload occurs the light-emitting unit generates prompting light for the purpose of identification. | 02-11-2010 |
