发明名称 Bulb socket and lighting device
摘要 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.

主权项 1. A bulb socket arranged to hold a bulb having a light-emitting portion and a base portion, the bulb socket comprising, a socket body having an insertion hole arranged to receive the base portion of the bulb, and a terminal clamp attached to the socket body to be electrically connected to the base portion, wherein the terminal clamp includes a fixation portion arranged to be fixed to the socket body, and a pair of terminal portions extending from the fixation portion and arranged to sandwich the base portion of the bulb, wherein each of the pair of terminal portions includes a spring portion arranged to exert a pushing force in a direction of sandwiching the base portion of the bulb, and a contact portion provided at a tip of the spring portion, wherein the socket body is provided with a pair of regulation portions respectively arranged in a way opposing to each of the terminal portions, the pair of regulation portions being arranged to abut against the terminal portions from an opposite side with respect to the base portion so as to restrict an amount of elastic deformation of the spring portions within a predetermined numerical range, wherein in the terminal clamp, a first center axis extends from the fixation portion to the pair of terminal portions and a second center axis intervenes between the pair of terminal portions, the first and second center axes being eccentrically arranged with respect to each other, and wherein in the socket body, each pair of regulation portions has an equivalent distance between the corresponding portions of the pair of terminal portions.
