Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a fusible link device, particularly a fusible link device that is directly connected to a vehicle battery terminal.

BACKGROUND ART The electrical system of a vehicle is supplied with current from a battery, and fuses are provided in each part of the vehicle to prevent excessive current from flowing in the event of an accident such as a short circuit in each electrical component.

As a type of fuse, a fusible link is provided for electrical circuits that require a relatively large current, and in recent years, this fusible link has been formed as a detachable element, and this is used as a fusible link storage box. It will be installed.

Such a fusible link device is usually placed near a battery terminal, and in recent years, the power supply side terminal plate of the fusible link device has been connected to the battery terminal directly or via a battery press terminal.

However, with this arrangement of the fusible link device, there has been a problem in coordination with the starter cable for the starter motor, which requires an extremely large current, during installation work.

Figure 1 shows the connection between the conventional fusible link device and starter cable to the battery terminal.
A battery press terminal 10 is firmly tightened and fixed in advance to a battery post (not shown), and this terminal screw 1
Various battery terminals are connected to 0a.

The conventional fusible link device 12 has a power supply side terminal plate 14 inside thereof, and the terminal screw 1 is connected to the terminal screw 1 by a terminal hole 16a formed in a protruding terminal 16 that protrudes from the storage box to the outside.
A connection is made with 0a.

Although not shown in detail, the fusible link device 12
A fusible link is removably attached inside, and its power supply side terminal is connected to the power supply side terminal board 14, and the other circuit side terminal is connected to a predetermined electrical circuit.

In the conventional device, it is necessary to connect the power supply side terminal plate 14 of the fusible link device 12 shown in FIG. 1 to the battery press terminal 10 and also connect the starter cable 18 to the battery press terminal 10 at the same time. Conventionally, the terminal hole 20a of the starter terminal 20 caulked and fixed to the tip of the starter cable 18 is engaged with the terminal screw lea of the battery press terminal 10 at the same time as the terminal hole 16a of the fusible link device. At the same time, screws were tightened and fixed using nuts not shown.

However, with this conventional device, two parts must be assembled at the same time, resulting in a problem of poor work efficiency.

Purpose of the invention The present invention has been devised in view of the above-mentioned conventional problems, and its purpose is to provide an improved fusible link that allows both the fusible link and the starter cable to be assembled and connected to battery terminals extremely easily. The goal is to provide equipment.

Structure of the Invention In order to achieve the above object, the present invention includes a fusible link storage box into which a fusible link is detachably attached, and a fusible link storage box with one end fixed in the storage box to connect a power terminal of the fusible link with an electrical connection. A fusible link device includes a power supply side terminal board that is electrically conductive and whose other end protrudes from a storage box and is connected to a battery terminal, the power supply side end of the starter cable is connected to the power supply side terminal board within the storage box. The terminal board is characterized in that the terminal board shares the connection with the battery terminal for both the fusible link and the starter cable.

Example Preferred embodiments of the present invention will be described below based on the drawings.

A preferred embodiment of the fusible link device according to the present invention is shown in FIG. is battery press terminal 10
The terminal screw 10a is engaged with the terminal screw 10a.

The fusible link device 30 connects the fusible link storage box 38 to the fusible link storage box 38.
2 is removably attached, and the power supply terminal 40 and circuit terminal 42 of the fusible link 32 are inserted into predetermined positions in the storage box 38, and electrically connected to the power supply side terminal board 34 and the circuit cable 44 in the storage box 38. Connect to.

As shown in FIG. 3, the power supply side terminal plate 34 has a terminal hole 36 in which the protruding terminal 36 engages with the terminal screw 10a.
a is provided, and the other end fixed to the storage box 38 side is divided into two forked parts, and a fixing screw hole 46a is provided at the tip of the forked part 46.

As is clear from FIG. 2, the fixing screws 48 are engaged with both of the fixing screw holes 46a and the holes of the power terminals of the fusible links that have been installed in the storage box in advance, and the tips of the fixing screws 48 are By tightening the fixing nut 50, the power supply side terminal plate 34 can be firmly fixed in the storage box 38.

That is, in the embodiment, one end of the fixing nut 50 is press-fitted into a fixing groove 38a provided in the storage box 38, and therefore, the power supply side terminal board 34 is inserted into the storage box 38 via the fixing screw 48. can be firmly fixed.

In this fixed state, the power terminal 40 of the fusible link can be reliably electrically connected to the power terminal board 34.

Note that the circuit cable 44 is also electrically connected to the circuit terminal 43 of the fusible link by a fixing screw 52 and a fixing nut 54 in the same way as the power supply side terminal board 34 .
is held fixed.

A characteristic feature of the present invention is that a starter cable 56 is attached to the power supply side terminal plate 34 of the fusible link device 30.
are fixedly connected, and in the embodiment,
A starter cable 56 is caulked and fixed to a caulked end 58 provided at the lower end of the power supply side terminal plate 34.

Therefore, according to the present invention, the fusible link device 30
By directly fixing the power supply side terminal plate 34 to the battery press terminal 10 or a battery post (not shown), the power supply side connection of the starter cable 56 is automatically achieved, thereby significantly improving assembly workability. It becomes possible.

In this embodiment, the storage box 38 is further integrally formed with three opening/closing lids, namely, an opening/closing lid 60 for attaching/detaching the fusible link, an opening/closing lid 62 for the power supply terminal, and an opening/closing lid for the circuit terminal. 64 are provided.

These opening/closing lids 60, 62.degree. 64 are each made of plastic or the like and are integrally formed with the storage box 38.

The fusible link attachment/detachment opening/closing lid 60 is attached to the storage box 38.
The upper part of the waist fusible link 32 can be easily attached and detached.

Further, the power supply side terminal opening/closing cover 62 is used for attaching/detaching the power supply side terminal board 34, and similarly, the circuit terminal opening/closing cover 64 is used to attach/detach a predetermined circuit cable 44.

Therefore, if the necessary circuit terminals are connected to the fusible link device 30 in advance, the desired circuit connection and starter cable connection can be made by simply connecting the protruding terminal 36 of the power supply side terminal board 34 protruding from the device to the battery. It has the advantage that it can be done easily.

Effects of the Invention As explained above, according to the present invention, the predetermined circuit passing through the fusible link and the starter motor circuit can be connected to the power supply using a common terminal board, which significantly improves assembly work efficiency. becomes possible.
