Abstract

Fuse cavity structure includes fuses 10, 20 in which each of fusible elements 17, 27 for protecting a circuit from overcurrent is located between terminals 15 or 25, and a housing 59 in which the fuses 10, 20 are mounted; a part of a wall 65 of the housing 59 which partitions the fuse 10, 20 and fuse 10, 20 is removed thereby to form a notch 65 H in the wall 65; and space is proved between the fuses 10 or 20. The notch 65 H is formed by notching the wall 65 corresponding to at least a part of the fusible portion 17, 27.

Description

technical field [0001] The present invention relates to a fuse chamber structure in which various types of fuses can be attached, size reduction is performed, and improvement regarding heat generation is performed; and an electrical connection box equipped with the fuse chamber structure. [0002] The present invention further relates to a fuse chamber structure which can perform size reduction and in which various kinds of fuses can be attached and stably fixed, and also relates to an electrical connection box having the fuse chamber structure . Background technique [0003] Figure 7 One example about the structure of a conventional fuse attaching portion is shown, as shown in Unexamined Japanese Patent Laid-Open No. 2002-124175. [0004] The tab terminal pair 155 protrudes from the insulating case 153 in the direction in which they are attached into the fuse attaching portion 120 , which constitutes the first fuse 150 . The tab terminal pair 155 constituting the first f...
