  • Patent number: 9484696
    Abstract: A pair of terminal portions of a bus bar is composed of a first terminal portion and a second terminal portion extended along a sidewall of the base portion. Each of the first and second terminal portions has a spring portion for generating biasing force toward a direction of holding the base portion, and a contact portion provided on a tip of the spring portion. The contact portion of the first terminal portion abuts on a contact lead wire, and the contact portion of the second terminal portion abuts on the sidewall of the base portion, thereby the contact portions hold the base portion therebetween. In a natural condition that the bulb is not inserted and the spring portion is not elastically deformed, the pair of terminal portions is displaced from a center plane toward the one side corresponding to a projection size of the contact lead wire.

  • Patent number: 9466936
    Abstract: A bulb socket and a lighting system, which can reduce components and dimensions and improve a force for holding a bulb, are provided. A housing has an insertion hole including an opening for receiving a base portion of a bulb, and a plurality of projection portions projecting from a deep side wall of the insertion hole toward an opening side. The projection portions are opposed to each other so that the base portion is sandwiched therebetween. A distance between the projection portions is formed smaller than a cross-sectional dimension of the base portion. When the base portion is inserted into the insertion hole, the projection portions are elastically deformed away from each other, and contacts slidingly a surface of the base portion. The base portion is sandwiched by a biasing force of the elastically deformed projection portions in a biasing state, and thereby the bulb is held.

  • Patent number: 9331403
    Abstract: A pair of terminal portions of a bus bar (i.e. a terminal clamp) includes spring portions each of which is arranged to exert a pushing force in a direction of sandwiching a base portion of a bulb, and contact portions each provided at a tip portion of the spring portion. A housing (i.e. a socket body) includes regulation portions located on opposite side of the terminal portions and arranged to abut on the terminal portions from opposite side of the base portion to regulate elastic deformation amount of the spring portions to be within a predetermined value.

  • Publication number: 20160035508
    Abstract: Switch knobs have indication portions that are provided with various indications. The indications provided in the indication portions can transmit light that is emitted from a light-emitting diode and guided by a light guide member. The optical axes (Ax) of light beams that are emitted from the light-emitting diode and guided by the light guide member are directed to the eye points (IPd, IPn) of persons who are to manipulate the switch knobs, respectively.
