Abstract

There are provided a bulb socket and a lighting device which can reduce the number of components, reduce the size of the device and inhibit excessive deformation of a terminal clamp. A pair of terminal portions (64) of a bus bar (i.e. a terminal clamp) (6) include spring portions (65) each of which is arranged to exert a pushing force in a direction of sandwiching a base portion (22) of a bulb (2); and contact portions (66) each of which is disposed at a tip portion of the spring portion (65). A housing (i.e. a socket body) (31) includes regulation portions (37) located on opposite side of the terminal portions (64) and arranged to abut on the terminal portions (64) from the opposite side of the base potion (22) to regulate elastic deformation amount of the spring portions (65) to be within a predetermined value.

Description

technical field [0001] The invention relates to a light bulb socket arranged to hold a light bulb and to a lighting device. Background technique [0002] One example of a proposed bulb socket structure used in a vehicle-mounted interior lighting device provided at the roof of a vehicle such as an automobile is provided with a socket body made of resin for mounting such as a wedge-shaped base bulb Such a light bulb; and a pair of power supply terminals (ie, terminal clamps) provided at the socket body, wherein the base (base portion) of the light bulb is inserted into the mounting hole of the socket body, and the pair of power supply terminals Terminal clamping (for example, see Patent Document 1). For the bulb socket structure disclosed in Patent Document 1, as Figure 8 As shown, a pair of power supply terminals 101 is provided with a pair of holders 102 for holding a base 111 of a light bulb 110, so that by inserting the base 111 between the pair of holders 102, the pair ...
