Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fusible link holder for a fusible link used as protection for a charging circuit for an automobile.

As a first prior art fusible link holder, there is one shown in FIG. 1, for example.

This conventional fusible link holder consists of a pair of rectangular parallelepiped fusible link holder bodies 1a and 1b, and both ends of the fusible link 2 are inserted into the fusible link holder bodies 1a and 1b, respectively. There is. A fixed terminal 3 whose tip extends outward is disposed within one fusible link holder main body 1a, and the fixed terminal 3 is connected to one end of the fusible link 2. Further, an electric wire 4 connected to an automobile charging circuit is inserted into the other fusible link holder main body 1b, and the electric wire 4 is connected to the other end of the fusible link 2.

The externally extending tip of the fixed terminal 3 disposed on the fusible link holder main body 1a is fastened to the positive electrode post 6 of the battery 5 together with the battery cable terminal 7 with a bolt 8, making it fusible. The link holder main body 1a is directly attached to the positive electrode post 6. Note that a battery cable 9 for a headlight is connected to the battery cable terminal 7.

However, in the fusible link holder of the first conventional example, one of the fusible link holders of the pair of fusible link holder bodies 1a and 1b to which the fusible link 2 is connected The main body 1a is attached to the positive electrode post 6 of the battery 5, and the other fusible link holder main body 1b is suspended via the fusible link 2, so that one fusible link holder When the main body 1a is attached to the positive electrode post 6, an external force is applied to the fusible link 2 itself due to the weight of the other fusible link holder main body 1b, and the vibration of the vehicle body causes the suspended The fusible link holder main body 1b may wander and cause poor contact between the fusible link holder main body 1a attached to the positive electrode post 6 and the fusible link 2, or the fusible link 2 may become attached to the positive electrode post. Fusible link holder main body 1b attached to 6
There was a problem with it falling off.

Therefore, there is a fusible link holder as shown in FIG. 2 as a second prior art fusible link holder invented to solve this problem.

This conventional fusible link holder includes a box-shaped housing 10, and the housing 10 is provided with a plurality of terminal insertion portions 12 into which a plurality of fusible links 11 are respectively inserted. Electric wires 13 connected to an automobile charging circuit are also inserted into each of these terminal insertion portions 12 .

Furthermore, a fixed terminal (not shown) that commonly connects one end of each of the fusible links 11 is provided in the terminal insertion portion 12 into which one end of each of the plurality of fusible links 11 is inserted. The other end of each of the plurality of fusible links 11 is connected to an electric wire 13 inserted into the terminal insertion part 12.

A vehicle body attachment piece 14 is provided on the side of the housing 10, and the vehicle body attachment piece 14 is fixed to the vehicle body 16 with screws 15, so that the housing 10 is attached to the vehicle body 16.

A fixed terminal disposed in a terminal insertion portion of a housing 10 attached to a vehicle body 16 is connected to a positive electrode post 6 of a battery 5 via a power supply cable 17.

However, in the fusible link of the second conventional example, the housing 10 is provided with a plurality of terminal insertion portions 12 into which a plurality of fusible links 11 are inserted, and the housing 10 is provided with a plurality of terminal insertion portions 12 on the side of the vehicle body. Since the mounting piece 14 is provided and the housing 10 is configured to be attached to the vehicle body 16 via the vehicle body mounting piece 14, the fusible link 1
1 is inserted into the terminal insertion part 12, so that it no longer swings around due to vibrations of the vehicle body, but the housing 10 is attached to the vehicle body 16 at a position away from the battery 5, making it difficult to insert the terminal. The power supply cable 17 that connects the fixed terminal arranged in the section 12 and the positive electrode post 6 of the battery 5 swings around due to the vibration of the vehicle body and comes into contact with the vehicle body, and the power supply cable 17 is rubbed against the vehicle body. This poses a problem in that it is undesirable in terms of safety and disaster prevention, as the core wire may be damaged and the core wire may be exposed, causing a shoot or breakage of the core wire.

This invention was made by focusing on such conventional problems, and includes an arm that is attached to a battery, and a housing that is detachably attached to the arm and into which a plurality of fusible links can be inserted. A fusible link holder comprising a housing, one end of which is connected to a locking plate provided on the side of the housing, a fusible link inserted into the housing, and the other end connected to the locking plate. and a conductive housing-side fixed terminal portion exposed from the horizontal arm portion, the arm being engaged with and attached to the electrode post of the battery;
