should be noted that in conventional fixed heated backlights the opposite ends of the bus bars are affixed to lead in wires electrically connected to suitable terminals in turn connected to the vehicle 39 s electrical system however in movable heated backlights such as would be incorporated in a tailgate or rear door of a station wagon for example it has been found impractical to employ such lead in wires because of the flexibility and increased length requirements and also because of their vulnerability to damage during movement of the heated backlight whether hingedly mounted for pivotal movement or for sliding movement within the door framework thus terminals 15 of substantially enlarged formations are provided on the bus bars 13 to engage when closed fixed contacts mounted on the vehicle and which constitute a part of the vehicle 39 s electrical system in order to protect the terminals 15 and preclude the removal of or damage to the frit composition constituting the terminals due to the impact or frictional engagement thereof with the vehicle 39 s electrical contacts connectors or striker plates 16 of a suitable electrically conductive durable metallic material are affixed as by soldering to the terminals 15 in a superimposed relation thereto thus the striker plate 16 absorbs the impact or frictional force otherwise imparted to the frit composition constituting the terminals 15 and thereby serves as a shield protecting the same preferably the striker plates 16 are prepared and initially provided with beads of solder 17 prior to their assembly onto the terminals 15 during a production run in a large volume operation in accordance with.
