Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fusible link box having a built-in fusible link for protecting a power supply wiring from an excessive current of a battery mounted on a vehicle or the like. In particular, the present invention relates to a fusible link box capable of efficiently performing a fusible link exchange operation. 2. Description of the Related Art FIG. 5 is a side view of a conventional fusible link box. FIG.
Shows a state in which the upper cover is opened, and FIG. 3C shows a state in which the upper cover and the lower cover are opened. In these drawings, reference numeral 100 denotes a fusible link box, which has a box main body 110 for housing a fusible link 101 therein. [0004] The upper and lower sides of the box main body 110 are both open, and an upper cover 120 is provided at the upper part thereof which can be opened and closed via a hinge. In addition, a box-shaped lower cover 130 slidable up and down is attached to a lower portion thereof. Further, a battery post cover portion 121 that covers a battery post 201 to be described later is integrally extended from the upper cover 120. [0005] One tab terminal 101b of the fusible link 101 housed in the box body 110 has:
The relay wire 140 is connected by the mounting bolt 102. In addition, the relay wire 140 is connected to an alternator (not shown). A power supply terminal 150 is connected to the other tab terminal (101c) of the fusible link 101 by a mounting bolt (102). Further, the power supply terminal 150 is connected to a battery connection terminal 202 by a nut 203, and the battery connection terminal 202 is connected to a battery post 201 of the battery 200. The head 101a of the fusible link 101 is protected by the upper cover 120, and the tab terminal 10 of the fusible link 101 is protected.
1b (101c) is protected by the lower cover 130. Further, the power supply terminal 150, the battery connection terminal 202, and the battery post 201 are protected by a battery post cover 121 formed integrally with the upper cover 120. Next, the operation of replacing the fusible link 101 in the conventional fusible link box 100 will be described. In the state shown in FIG. 5A, when exchanging the fusible link 101 due to the occurrence of an abnormality, the operator firstly as shown in FIG.
20 (and the battery post cover 121),
The battery post 201 is opened from the upper part of the box body 110. Then, the nut 203 is loosened, the power supply terminal 150 is removed from the battery connection terminal 202, and the fusible link box 100 is disconnected from the battery 20.
Separate from zero. Next, as shown in FIG. 5C, the lower cover 130 is slid downward to open both lower portions of the box body 110. Then, the mounting bolts 102 (,
102), and the tab terminals 101b (101c)
The connection between the relay wire 140 and the power supply terminal 150 is released. After that, the fusible link 101 is removed from the box body 110 and replaced with a new fusible link. However, in the above-described conventional fusible link box 100, the upper cover 120 and the lower cover 130 are divided, so that the step of opening the upper cover 120 and the sliding of the lower cover 130 are performed. Two steps were required. The lower cover 130 is slid up and down. The lower cover 130 is normally held on the box body 110 by locking claws (not shown).
Unless separated from the lower cover 130, the lower cover 130 could not be slid downward. For this reason, conventionally, when exchanging the fusible link 101, a step of separating the fusible link box 100 from the battery 200 was essential. As a result, in the conventional fusible link box 100, when replacing the fusible link 101, the step of opening the upper cover 120, the step of separating the fusible link box 100 from the battery 200, and the sliding of the lower cover 130 However, there is a problem that the efficiency of the replacement operation is low because three steps of the process for performing the replacement are required. The present invention has been made in view of the above problems, and an object of the present invention is to provide a fusible link box capable of efficiently performing a fusible link exchange operation. In order to achieve the above object, a fusible link box according to the present invention comprises: a box body having upper and lower sides of a housing for a fusible link; It is composed of a rotatably provided a cover member to the body, with the upper cover portion to which the cover member covers an upper portion of the housing portion, to the upper cover section, the lower cover portion for covering the lower sides of the housing part Hang down
