JPH04135143U - Spare fuse housing structure - Google Patents

Abstract

(57) [Summary] [Purpose] This is to prevent a spare fuse from being excessively inserted into the accommodating cylindrical portion of an electrical connection box or the like, thereby preventing it from being deformed or damaging the accommodating cylindrical portion. [Structure] A stopper f is provided on the bottom surface e of the accommodating cylindrical portion B for the fuse A, which has two leg-shaped tab terminals b protruding from the insulating main body portion a, with which the lower surface a ₁ of the insulating main body portion a collides. .

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is mainly used as a spare part in electrical junction boxes etc. used in automobile electrical circuits. The present invention relates to a housing structure for a fuse for use.

0002

[Conventional technology]

Fuse A used in automobile electrical circuits is made of synthetic resin, as shown in Figure 5. Two leg-shaped tab terminals b, b are protruded from the bottom of the insulating body part a made of fat, and the insulation is A so-called blade in which a fusing circuit is connected between tab-shaped terminals b and b within the main body part a. Type structure is used, and this is installed inside the electrical connection box or fuse box. When storing it as a spare part, insert it into the housing cylinder part B and insert it into the insulating body part a. Both sides c and c in the plate thickness direction are connected to the space between the opposing protrusions d and d in the housing cylinder part B. It is press-fitted in between (Figure 6).

0003 However, with this structure, if pressed strongly in the insertion direction, fuse A will be over-inserted. If the tab terminal b collides with the bottom surface e of the accommodating cylinder part B and becomes deformed, or the accommodating cylinder part There are drawbacks such as part B being damaged.

0004

[Problem that the idea aims to solve]

The present invention was developed by focusing on the above-mentioned points. This is to prevent excessive insertion of the keyword.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the present invention uses two wires protruding from the insulating body. At the bottom of the housing tube for a fuse having leg-shaped tab terminals, It is characterized by being provided with a stopper whose lower surfaces abut against each other.

[0006]

[Effect] The spare fuse inserted into the housing cylinder should be removed before the tab terminal abuts against the bottom surface. Supported by the topper.

[0007]

【Example】

Figures 1 and 2 show an electrical junction box C, in which fuses normally used for circuit connections are shown. A housing cylinder part B' for the fuse A' and a housing cylinder part B for the spare fuse A are provided. In order to facilitate identification when replacing the fuse, the spare housing cylinder part B is reserved for regular use. The height is shorter than that of the accommodating cylindrical portion B'.

[0008] The accommodating cylindrical portion B is integrally formed with the fuse box C from a synthetic resin material, and has two sets of opposing protrusions d and d as described above. As shown in FIGS. 3 and 4, a stopper f is erected toward the upper opening g at the longitudinally intermediate portion of the bottom surface e of the housing cylinder B. The standing height m ₁ of the stopper f from the bottom surface e is greater than the protruding length m ₂ of the tab terminal b of the fuse A.

In the above configuration, when the spare fuse A is inserted into the accommodating cylinder part B, the lower surface a ₁ of the insulating body part a abuts against the stopper f, and a certain insertion depth is regulated, and in this state, the insulation The side surface c of the main body portion a is pressed against and held by the protrusion d, and the tab terminal b is separated from the bottom surface e.

0010

[Effect of the idea]

As described above, the present invention has two leg-like tab terminals protruding from the insulating main body. At the bottom of the housing tube for the fuse, there is a stock with which the lower surface of the insulating body abuts. Since the fuse is equipped with a It has the effect of preventing losses.
