Problems solved by technology

[0005] However, since the organic insulating protector covers the inorganic insulator, when there is a flame around the lighting fixture in the event of a fire, there is a fear that the organic insulating protector of the terminal board will be directly exposed to the flame.
[0006] In addition, it is also considered to use an inorganic insulator instead of an organic insulating protector to form a terminal pad to obtain a terminal pad with excellent fire resistance. However, due to the large shrinkage rate of the inorganic insulator during the sintering process, it is easy to generate twists or pores (ひけ ), so it is difficult to have high dimensional accuracy, and it is difficult to achieve mass production

Abstract

The invention solves the problem of being difficult to mass-produce due to being difficult to take out dimensional accuracy since an inorganic insulator is large in a shrinkage factor generated in a sintering process and easily causes a twist and a shrink. This invention has a fixed module 19 of an organic insulator having a conductive part 23 connecting an electric wire, a conductive part storage part 24 storing the conductive part 23 and a positioning recessed part 25 in an outer peripheral part, a terminal block body 13 of a substantially box-shaped inorganic insulator having an opening part having an opening one surface, having a positioning projection part 20 for guiding by abutting on the positioning recessed part 25 of the fixed module 19 and storing the fixed module 19, and a terminal block cover 14 of an inorganic insulator covering the periphery of the fixed module 19 by abutting on the opening part of the terminal block body 13. By covering the contour of the fixed module 19 with the terminal block body 13 and the terminal block cover 14 molded by the inorganic insulator, a terminal block 12 superior in fire resistance can be provided, and the conductive part 23 can be accurately stored in the conductive part storage part 24.

Description

technical field [0001] The present invention relates to a terminal block that utilizes an inorganic insulator to improve fire resistance. Background technique [0002] For example, Patent Document 1 discloses that an inorganic insulator is arranged in an organic insulating protective body and is formed in a flat plate shape longer than the charging portion, so as to prevent damage to the insulation of the protective body due to partial discharge of the charging portion. The inorganic insulator is made into a flat plate, which has good dimensional stability, easy assembly, and miniaturization. Furthermore, by making the inorganic insulator longer than the charging part, even if the insulation deteriorates, arc generation can be prevented, thereby avoiding the fear of fire. . [0003] [Patent Document 1] JP-A-7-65897 (lines 4 to 9 of paragraph [0005], lines 1 to 5 of paragraph [0014]) [0004] Conventional terminal boards have inorganic insulators in an organic insulating pr...
