摘要： There has been such a problem that when a lighting circuit in a shell member ignites, a connecting member used in an LED bulb is thermally fused and deformed and the connector could ignite as well because the connecting member is made of synthetic resin, thereby electrically insulating a shell member and a base.
A connector according to the present invention connects a conductive member such as a radiating section which radiates generated heat from a heat source functioning with supplied power and a power connection section which connects with an external power source supplying power to the heat source.
The connector is characterized by having electrical insulation properties in order to electrically insulate the conductive member and the power connection section, and having thermal resistance in order to prevent deformation due to heat from the heat source.
