Room lamp provided with insulating structure between bus bars thereof
First Claim
1. In a vehicle room lamp comprising a number of bus bars disposed on a back surface of a case provided with a switch for controlling an illumination lamp such as a light bulb or flashing of the light bulb, the bus bars for achieving flashing of the illumination lamp being integrated via bridge portions, the bus bars being electrically separated by cutting and bending upward the bridge portions at positions of holes formed on the case at positions corresponding to the bridge portions in a state of being fitted into the grooves formed on the case, wherein short circuit between the bus bars is prevented by fitting insulating members molded by relatively flexible resin into grooves in which the bus bars are fitted and fitting projections projecting from the insulating members into the holes formed on the grooves to cover exposed surfaces of the bus bars at least entirely over a portion where the mutual distance of the bus bars is reduced.

Abstract
Switch-controlled vehicle room lamps are provided with an insulating structure between bus bars disposed on a back surface of a case Short circuiting between the bus bars is prevented by fitting insulating members molded from a relatively flexible resin into grooves in which the bus bars are fitted to cover exposed surfaces of the bus bars at least entirely over a portion where the mutual distance of the bus bars are reduced. In some embodiments, the insulating members are formed with projections which are adapted to be fit within holes of the case into which severed bridge portions of the bus bar extend. The projections may advantageously be provided with an acute-angled distal end and a constriction at a midsection thereof.

3. A vehicle room lamp comprising:
-
a case having case walls defining therebetween a plurality of grooves and establishing a space for retaining an illumination lamp therein; a plurality of bus bars operably connected to the illumination lamp so as to supply electrical power thereto, wherein each of the bus bars is positioned in a respective one of the grooves; and an insulating structure to prevent short-circuiting between the bus bars, the insulating structure including insulating members formed of a relatively flexible resin, the insulating members being resiliently fitted within each of the grooves between the case walls so as to be in covering contact with the bus bar positioned therein. - View Dependent Claims (4, 5, 6, 7, 8, 9)
