A large current fuse for direct coupling to a power source which comprises a fuse body 2A electrically connected to a battery post 4a of a battery 4 by way of a power source side terminal 5, and a resin case 3A which partially covers the fuse body, is characterized in that the fuse body 3A consists of a power supply terminal plate 6 in a rectangular shape having the power source side terminal connected to one end thereof and at least one connecting terminal plate 8 integrally formed with at least one of both sides of the power supply terminal plate in a longitudinal direction by way of an L-shaped fusible member, the connecting terminal plate being positioned at the same side as the power supply terminal plate with respect to an extension line extending along the other end of the power supply terminal plate so as to shorten a distance D of the large current fuse protruding from the battery, a portion of an outer peripheral edge of the connecting terminal plate being substantially along the extension line.
Description
BACKGROUND OF THE INVENTION
1. Technical Field to which the Invention Belongs
The present invention relates to a large current fuse for direct coupling to a power source which can be directly coupled to a battery.
2. Related Art
Generally, a battery is mounted inside a body of an automobile as a supply source of electric power, and a large current fuse is electrically connected to a battery post of the battery by way of power source side terminal. An example of general large current fuses is illustrated in FIG.
13
.
As shown in
FIG. 13
, the large current fuse
80
includes a fuse body
83
which connects a first terminal
82
to a power source side terminal
81
, and a resin case
84
which covers an outer face of the fuse body
83
. The fuse body
83
includes a connecting hole (not shown) formed in one end thereof, a fusible member
85
arranged at an intermediate portion, and a stud bolt
86
which is provided so as to project from the other end thereof. A power source side stud bolt
81
a
provided in the power source side terminal
81
is inserted into the connecting hole, and a nut
87
is screwed onto the power source side stud bolt
81
a
. The fusible member
85
is adapted to fuse by self heating only when an excess current flows. The first terminal
82
is fixed to the stud bolt
86
by screwing a nut
88
.
In order to minimize a distance (protruding allowance) d of the large current fuse
80
protruding from an outer face
89
b
of the battery
89
after the large current fuse
80
has been assembled to a battery post
89
a,
the large current fuse
80
is formed in an L-shape so as to extend along the battery
89
. A second terminal
90
may be co-clamped to the power source side stud bolt
81
a
of the power source side terminal
81
together with the large current fuse
80
.
However, when the large current fuse
80
has been. assembled to the battery post
89
, the stud bolt
86
is directed laterally, therefore connecting workability of the first terminal
82
to the large current fuse
80
is deteriorated. Moreover, since the large current fuse
80
is formed in L shape, there is a drawback that the second terminal
90
which is co-clamped to the power source side terminal
81
together with the large current fuse
80
is restricted by a bent portion
80
a
of the large current fuse
80
. Although this drawback may be overcome by making a linear part
91
a
of the large current fuse
91
longer as shown in
FIG. 14
, it has been disadvantageous that the protruding distance d′ of the large current fuse
91
becomes longer.
SUMMARY OF THE INVENTION
In view of the above described problems, it is an object of the invention to provide a large current fuse for direct coupling to a power source in which the connecting workability of the first terminal to the large current fuse will be improved and a degree of freedom of the terminal to be co-clamped with the power source side terminal will be enhanced.
In order to attain the above described object, the invention is embodied by a large current fuse adapted to connect a power source side terminal attached to a battery post of a battery to at least one terminal, said fuse comprising:
a fuse body including:
a power supply terminal plate in substantially rectangular shape, one end of said power supply terminal plate being connectable to said battery post; and
at least one connecting terminal plate located in a direction perpendicular to a first direction with respect to said power source side terminal plate, said first direction defined by said fuse body elongating from said battery post; and
at least one fusible member connecting said power supply terminal plate to said at least one connecting terminal plate, respectively;
wherein an imaginary line extends along the other end of said power supply terminal plate and is substantially perpendicular to said first direction, said at least one connecting terminal plate is positioned at same side as said power supply terminal plate with respect to said imaginary line, and a outer peripheral edge of said connecting terminal plate is substantially along said imaginary line.
The large current fuse for direct coupling to the power source is further characterized in that the connecting terminal plate is positioned on a same plane as the power supply terminal plate so that terminals can be co-clamped to the power source side terminal with the power supply terminal plate, and that the connecting terminal plate has a stud bolt which projects in a direction opposite to a direction of mounting the power source side terminal on the battery post so as to connect the other terminals thereto.
As described above, the large current fuse for direct coupling to the power source is composed of the fuse body and the resin case which partially covers the fuse body. The fuse body consists of the power supply terminal plate in a rectangular shape, and the connecting terminal plate which is integrally formed with at least one side of both sides of the power supply terminal plate in a longitudinal direction thereof by way of the fusible member. The power supply terminal plate and the connecting terminal plate are positioned at the same side with respect to an extension line extending along the other end of the power supply terminal plate, and a portion of an outer peripheral edge of the connecting terminal plate is substantially along the extension line. Therefore, when the large current fuse has been assembled to the battery post, the distance of the large current fuse protruding from the battery becomes shorter than in the conventional example.
As described above, the connecting terminal plate is positioned on the same plane as the power supply terminal plate and has the stud bolt which projects in a direction opposite to a direction of mounting the power source side terminal on the battery post. Therefore, the large current fuse is flat in shape (flat shaped) as compared with the conventional large current fuse. Moreover, even after the large current fuse has been assembled, the stud bolt of the connecting terminal plate projects upward from the above described same plane.

DETAIL DESCRIPTION OF PREFERRED EMBODIMENTS
Now, an embodiment of the invention will be described by way of example with reference to the drawings.
FIGS. 1
to
8
show a first embodiment of the large current fuse for direct coupling to a power source (hereinafter referred to as the large current fuse) according to the invention.
As shown in
FIG. 1
, this large current fuse
1
A includes a fuse body
2
A which is electrically connected to a battery post
4
a
of a battery
4
by way of a power source side terminal
5
and a resin case
3
A which partially covers the fuse body
2
A by resin molding.
As shown in
FIGS. 1 and 2
, the fuse body
2
A includes a power supply terminal plate
6
in a rectangular shape, and a first connecting terminal plate
8
which is integrally formed with the power supply terminal plate
6
by way of a fusible member
7
at a right side
6
a
of the power supply terminal plate
6
in a longitudinal direction. The case is almost the same also when the first connecting terminal plate
8
is arranged at a left side
6
b
of the power supply terminal plate
6
.
The power supply terminal plate
6
is provided with a connecting hole
9
at its one end. The first connecting terminal plate
8
is formed in a rectangular shape and has a bolt hole
10
slightly remote from its center toward its other side
8
b.
The fusible member
7
includes a crank shaped fusible arm
11
, a fusing portion
12
formed at an intermediate part of the fusible arm
11
, and a pair of caulking pieces
13
,
13
provided at both sides of the fusing portion
12
respectively. One end of the fusible arm
11
is connected to the right side
6
a
close to one end
6
c
of the power supply terminal plate
6
, and the other end of the fusible arm
11
is connected to one end
8
a
of the first terminal plate
8
. Alternatively, the one end of the fusible arm
11
can be connected to an intermediate part of the power supply terminal plate
6
or the right side
6
a
close to the other end
6
d
thereof.
The fusing portion
12
is formed thinner than the fusible arm
11
, therefore the fusing portion
12
is fused by self heating when an excess current flows in the large current fuse
1
A. A metal chip
14
, for example of a metal alloy of tin, lead, etc. is caulked by a pair of the caulking pieces
13
,
13
.
The power supply terminal plate
6
and the first connecting terminal plate
8
are located at a same side with respect to an extension line L extending along the other end
6
d
of the power source terminal plate
6
. Moreover, the power supply terminal plate
6
and the first connecting terminal plate
8
are arranged in such a manner that the other end
8
b
of the first connecting terminal plate
8
extends along the extension line L. In addition, the power supply terminal plate
6
and the first connecting terminal plate
8
are arranged substantially on a same plane.
As shown in
FIG. 1
, a stud bolt
15
is provided in a bolt hole
10
of the first connecting terminal plate
8
so as to project in an upward direction. The upward direction means a direction opposite to a direction of mounting the power source side terminal
5
on the battery post
4
a.
As shown in
FIGS. 1 and 3
, the resin case
3
A partially covers the above described fuse body
2
A by resin molding the fuse body
2
A. The resin molding is conducted after the stud bolt
15
has been screwed (fixed) into the bolt hole
10
of the first connecting terminal plate
8
.
Three part of a surface of the power supply terminal plate
6
between its intermediate portion and the one end
6
c;
a surface of the first connecting terminal plate
8
; and a back face of the power supply terminal plate
6
respectively is exposed from the resin case
3
A, therefore a power source connecting part
20
and a first terminal connecting part
21
are formed. A surface and a back face of the fusible member
7
are also exposed from the resin case
3
A. Transparent covers
17
are provided above the surface and below the back face of the fusible member
7
respectively. The transparent covers
17
are fixed to the resin case
3
A by means of locking means
17
′. Therefore, the fusible member
7
, particularly the fusing portion
12
can be easily checked visually through the transparent covers
17
.
On a surface of the resin case
3
A, a radiating fin
23
is formed between the intermediate portion and the other end
6
d
of the power supply terminal plate
6
. A plurality of thin radiating plates
23
a
constituting the radiating fin
23
are arranged in parallel to a longitudinal direction of the power supply terminal plate
6
. In order to form the radiating fin
23
on the resin case
3
A, a part of the resin case
3
A corresponding to a part of the power supply terminal plate
6
between the intermediate portion and the other end
6
d
must be formed thicker, and therefore, strength (rigidity) of the resin case can be made larger (stronger). Moreover, because a surface area of the resin case
3
A can be made larger due to a plurality of the radiating plates
23
a
thus arranged, radiation efficiency can be improved.
On the surface of the resin case
3
A corresponding to a periphery of the first terminal connecting part
21
, that is, a periphery of the first connecting terminal plate
8
, a first positioning rib
21
a
is provided at the resin case
3
A in parallel to the above mentioned longitudinal direction.
As shown in
FIGS. 3 and 4
, a pair of motion preventing ribs
6
e,
6
e
are provided so as to project from a back face of the resin case
3
A in parallel to the longitudinal direction of the power supply terminal plate
6
. These motion preventing ribs
6
e
can prevent a co-clamping terminal
26
(
26
′) in
FIG. 8
from a lateral slippage (slippage in a direction perpendicular to the above mentioned longitudinal direction).
Reverting to
FIG. 1
, the power source side terminal
5
includes a caulking bore
5
a,
an adjusting screw
5
b
for adjusting the diameter of the caulking bore
5
a,
and a power source side stud bolt
5
c
to be inserted in the connecting hole
9
of the power supply terminal plate
6
.
Referring now to FIG.
1
and
FIGS. 5
to
8
, a manner of assembling the large current fuse
1
A to the battery
4
and a manner of electrically connecting a first terminal
25
and the co-clamping terminal
26
to the large current fuse
1
A will be described.
As shown in
FIG. 1
, the power source side stud bolt
5
c
is inserted into the connecting hole
9
of the large current fuse
1
A. Then, a nut
28
is screwed on the power source side stud bolt
5
c
to electrically connect the power source side stud bolt
5
c
to the power source connecting part
20
.
As shown in
FIGS. 5 and 6
, the battery post
4
a
is inserted into the caulking bore
5
a
of the power source side terminal
5
. The caulking bore
5
a
is decreased in diameter by rotating the adjusting screw
5
b
clockwise or counterclockwise to rigidly fix the power source side terminal
5
to the battery post
4
a.
Thus the large current fuse
1
A is assembled (directly coupled) to the battery post
4
by way of the power source side terminal
5
. Because the fuse body
2
A of the large current fuse
1
A is formed in such a shape as described above, the distance D of the large current fuse
1
A protruding from the battery
4
after assembled can be made shorter (smaller). Accordingly, on occasion of assembling the large current fuse
1
A to the battery
4
, a mounting space for the large current fuse
1
A can be saved. In addition, even in case where areas surrounding the battery
4
are complicated (crowded), the mounting space for the large current fuse
1
A can be amply secured.
As shown in
FIGS. 5 and 7
, when the large current fuse
1
A is assembled to the battery
4
, the first terminal connecting part
21
is directed upward (in a direction opposite to the direction of mounting the large current fuse
1
A on the battery
4
). Accordingly, the stud bolt
15
is also directed upward. The first terminal
25
is connected to an electric wire
30
branched from a non-shown wire harness, and the co-clamping terminal
26
is connected to another electric wire (not shown) which is also branched from the wire harness. The stud bolt
15
is inserted in a connecting hole (not shown) in the first terminal
25
, and the first terminal
25
is press fitted to the stud bolt
15
. The first terminal
25
which is press fitted is arranged at a determined position by means of the first positioning rib
21
a
of the resin case
3
A. The first terminal
25
is electrically connected to the first terminal connecting part
21
by screw fitting a nut
29
to the stud bolt
15
. In this state, the connected position of the first terminal
25
is in parallel to the above mentioned longitudinal direction. Because the stud bolt
15
of the large current fuse
1
A is directed upward, the first terminal
25
can be easily connected to the large current fuse
1
A. As described above, the connecting work can be improved. Particularly, even though the wire harness disposed inside the vehicle has no excess length, the connecting work can be easily performed.
Moreover, because the large current fuse
1
A is formed in a rectilinear shape different from the general large current fuse, the co-clamping terminal
26
can be electrically connected to the power source connecting part
20
as shown in
FIG. 7
without being restricted due to the shape of the large current fuse
1
A. In other words, the large current fuse
1
A and the co-clamping terminal
26
can be easily clamped together to the power source side stud bolt
5
c
of the power source side terminal
5
. Because the restriction can be abolished by this, the co-clamping terminal
26
′ having a different length can also be freely connected. Thus, the degree of freedom of connecting the co-clamping terminal
26
(
26
′) which can be coupled together to the power source side terminal
5
can be enhanced as shown in FIG.
8
.
For connecting the co-clamping terminal
26
to the power source side stud colt
5
c
of the power source side terminal
5
together with the large current fuse
1
A, a connecting hole (not shown) in the co-clamping terminal
26
is mounted on, and next a nut is screwed on the power source side stud bolt
5
c.
On this occasion, the co-clamping terminal
26
is interposed between the power source side terminal
5
and the large current fuse
1
A.
Further, by providing the first positioning rib
21
a
of the resin case
3
A in a direction perpendicular to the above mentioned longitudinal direction, the first terminal
25
can be connected to the first terminal connecting part
21
of the large current fuse
1
A in the direction perpendicular to the longitudinal direction. With this arrangement, a distance D of the large current fuse protruding from the battery
4
inclusive of the first terminal
25
which is connected to the first terminal connecting part
21
can be further shortened.
FIGS. 9
to
12
show a second embodiment of a large current fuse for direct coupling to a power source according to the invention. The same members as in the first embodiment are denoted with the same reference numerals to omit a detailed explanation.
As shown in
FIG. 9
, this large current fuse lB is composed of a fuse body
2
B and a resin case
3
B which partially covers the fuse body
2
B as in the first embodiment.
As shown in
FIGS. 9 and 10
, the fuse body
2
B includes a power supply terminal plate
6
, a first connecting terminal plate
8
and a second connecting terminal plate
38
which are respectively connected by way of fusible members
7
to both sides
6
a,
6
b
of the power supply terminal plate
6
in a longitudinal direction. The first connecting terminal plate
8
and the second connecting terminal plate
38
are arranged and constituted symmetrically with respect to the power source terminal plate
6
. The power supply terminal plate
6
and the first and the second connecting terminal plates
8
,
38
are positioned at the same side with respect to an extension line L of the other end
6
d of the power supply terminal plate
6
. The other ends
8
b,
38
b
of the first and the second connecting terminal plates
8
,
38
are arranged substantially along an extension line L. All of the power supply terminal plate
6
and the first and the second connecting terminal plates
8
,
38
are positioned on a same plane.
As shown in FIG.
9
and
FIG. 11
, three parts of a surface of the power supply terminal plate
6
between the intermediate portion and the one end
6
c,
surfaces of the first connecting terminal plate
8
and the second connecting terminal plate
38
, and the back face of the power supply terminal plate
6
are exposed from the resin case
3
B, therefore a power source connecting part
20
, a first terminal connecting part
21
, and a second terminal connecting part
22
are respectively formed. The power source connecting part
20
, the first terminal connecting part
21
, and the second terminal connecting part
22
are respectively in such shapes as to correspond to shapes of counterpart members to be connected. Both the surfaces and the back faces of the fusible members
7
are also exposed. Transparent covers
17
are provided above and below the fusible members
7
. A radiating fin
23
is formed on the resin case
3
B corresponding to an area of the power supply terminal plate
6
between the intermediate portion and the other end
6
d.
As shown in
FIGS. 9 and 12
, the resin case
3
B is provided with a first and a second positioning ribs
21
a,
22
a
so as to project therefrom at the positions corresponding to the peripheries of the first terminal connecting part
21
and the second terminal connecting part
22
, that is, the peripheries of the first connecting terminal plate
8
and the second connecting terminal plate
38
. The second positioning rib
22
a
is uprightly provided in parallel to the above mentioned longitudinal direction. At least one of the first and second positioning ribs
21
a,
22
a
can be positioned in a direction perpendicular to the longitudinal direction.
A manner of assembling the large current fuse
1
B to the battery
4
is the same as in the first embodiment, and so, the explanation will be omitted.
Referring to
FIG. 9
, a manner of electrically connecting a first terminal
25
, a second terminal
35
, a third terminal
36
and a fourth terminal
37
to the large current fuse
1
B will be described.
As seen in
FIG. 9
, the first terminal
25
, the second terminal
35
, the third terminal
36
and the fourth terminal
37
are respectively connected to end portions of a plurality of electric wires
30
,
31
,
30
′,
31
′ branched from the wire harness which is disposed in a vehicle (not shown).
As seen in FIG.
9
and
FIG. 12
, after the large current fuse
1
B has been assembled to the battery
4
by way of the power source side terminal
5
. The first terminal
25
is electrically connected to the first terminal connecting part
21
and the third terminal
36
to the third terminal connecting part
22
respectively in the same manner as in the first embodiment. Although the first terminal
25
is in a rectangular shape and the third terminal
36
is in a round shape in
FIG. 9
, they may be vice versa, or both of them may be in the same shape of either one of the above shapes.
Connection of the second terminal
35
and the fourth terminal
37
to the large current fuse
1
B is conducted before the large current fuse
1
B is assembled to the battery
4
. In other words, respective connecting holes
35
a,
37
a
of the second terminal
35
and the fourth terminal
37
is inserted into the power source side stud bolt
5
c
of the power source side terminal
5
. When the power source side stud bolt
5
c
is inserted into the connecting hole
9
of the power source connecting part
20
, both the second and the fourth terminals
35
,
37
are interposed between the power source side terminal
5
and the large current fuse
1
B in a sandwich shape. In this state, the power source side stud bolt
5
c
is screwed by a nut
28
. Accordingly the second and the fourth terminals
35
,
37
can be clamped together with the large current fuse
1
B. The second terminal
35
and the fourth terminal
37
which are clamped together in two layers are directed opposite to each other. In short, the second terminal
35
is arranged at a side of the first terminal
25
, while the fourth terminal
37
is arranged at a side of the third terminal
36
. The first terminal
25
and the third terminal
36
are substantially perpendicular to an axial direction of the electric wire
30
(
30
′). The second terminal
35
and the fourth terminal
37
are substantially perpendicular to an axial direction of the electric wire
31
(
31
′), and are in a state where they are rotated by 90 degree around the axial direction of the electric wire
31
(
31
′) on a plane perpendicular to the axial direction. This means that the second terminal
35
and the fourth terminal
37
are rotated by 90 degree from the first terminal
25
and the third terminal
36
.
As shown in
FIG. 12
, the two co-clamping terminals
26
,
26
′ can be clamped together to the power source connecting part
20
of the large current fuse
1
B, while the connection of the first terminal
25
and the third terminal
36
are connected thereto. In both the first and the second embodiments, numeral
39
represents holes at which connecting pieces (not shown) have been formed at stamping a metal plate (not shown) in order to facilitate resin forming of the fuse body

. However, other types of application are also possible.
As described above, according to the invention, at least one side of both the longitudinal sides of the power supply terminal plate in a rectangular shape are integrally provided with at least one connecting terminal plate by way of the fusible member. The power supply terminal plate and the connecting terminal plate are arranged at the same side with respect to the extension line extending along the other end of the power supply terminal plate. Accordingly, when the large current fuse has been assembled to the battery by way of the power source side terminal, the distance of the large current fuse protruding from the battery can be shortened. This can prevent interference between the electric parts mounted around the battery and the large current fuse.
In addition, because the protruding distance can be thus shortened, the large current fuse can be reliably assembled to the battery, even in case where the mounting space in the vehicle in which the large current fuse is to be assembled to the battery is narrow.
According to the invention, the connecting terminal plate is disposed on the same plane as the power supply terminal plate, and has the stud bolt which projects in a direction opposite to the direction of mounting the power source side terminal on the battery post. Accordingly, the shape of the large current fuse can be made flat as compared with the general large current fuse. This means that when the terminals are clamped to the power source side terminal together with the power supply terminal plate, those restrictions due to the shape of the large current fuse can be abolished as compared with the conventional fuse. This can improve the degree of freedom of arranging (fixing) the terminals to be clamped together with the power supply terminal plate by means of the power source side terminal.
Further, even after the large current fuse has been assembled to the battery, the other terminals can be more easily connected than in the conventional example, since the stud bolt of the large current fuse projects upward. The connecting work of the other terminals to the large current fuse can be thus improved.
