An electrical cord 10.11 is connected thereto. The coupler terminal 8.9 is formed by bending an elastic metal plate, and has the positive terminal 4 and the negative terminal 5 inside it.
is press-fitted with a predetermined pressure.

Next, the operation of the embodiment of the present invention having the above-described configuration will be explained.

To connect both terminals 4.5 of the batch IJB and the electric cord 10°11, insert the guide groove 7 into the guide protrusion 3 of the battery case 1.
This is done by pushing the coupler 6 into the battery case 1 while engaged with the coupler 6.

End face 6 of coupler 6. When the terminal moves forward to a position where it contacts the side wall 22 of the stepped portion 2, the positive terminal 4 and the negative terminal 5 fit into the coupler terminals 8 and 9, respectively, and are connected. At this time, even if you try to insert the coupler 6 upside down, the guide protrusion 3 and the guide groove 7 will not engage, so the coupler 6 will not be easily inserted.
You can check the connection direction.

2 and 3 show a second embodiment of the present invention, in which a guide protrusion 3 formed on a battery case 1 is provided with a detachable fuse holder 12 in its internal space. The positive terminal of battery B is
A first positive terminal 4° is directly connected to the coupler terminal 81 from the positive terminal of the battery B, and a second positive terminal 4□ is connected from the positive terminal of the battery B to the coupler terminal 82 via the fuse attached to the fuse holder 12. It consists of two terminals. The first positive terminal 41 is connected to the electrical cord 10. The second positive terminal 4. is connected to other electrical equipment 14 such as a lamp that consumes relatively little power, thereby preventing the fuse from blowing out when the starter motor 13 is in use.

Therefore, it is possible to obtain the same effect as the previous embodiment in this embodiment as well, and in addition, since there is no need to interpose a fuse holder in the middle of the wire harness, the area around the battery case 1 This makes it easier to route the wire harness.

The coupler terminal 8 connected to is directly connected to the electric cord 10° extending to the starter motor 13, and also connected to the electric cord 10□ extending to the lamp and other electrical components 14 via a fuse mounted inside the fuse holder 12. has been done.

Therefore, in this embodiment as well, the wiring harness can be easily routed, and the same effects as in the second embodiment can be achieved.

5 and 6 show a fourth embodiment of the present invention, in which a locking claw 15 is provided on the coupler 6 side in order to lock the coupler 6 coupled to the battery case 1, and the battery case It is characterized in that a locked portion 16 with which the locking pawl 15 engages is provided on the first side. That is, the locking claw 15 is pivotally supported via a pin 18 to support brackets 17 protruding from both left and right sides of the coupler 6 so as to be openable and closable, and the locking surface 151 and the guide surface 15. A spring 19 biases the distal end portion in the closing direction. On the other hand, on the battery case 1 side, a bottom wall 21 and a side wall 2. The locked portion 16 is integrally formed with a locking hole 16 in the center of which the locking surface 151 of the locking claw 15 engages.
, is open.

According to this embodiment, when the guide groove 7 of the coupler 6 is engaged with the guide protrusion 3 of the battery case 1 and pushed in, the guide surface 152 comes into contact with the edge of the locked part 16, and the locking claw 15 expands against the spring 19, and the guide surface 15. When it gets over the edge of the locked portion 16, the locking pawl 15 closes due to the elastic force of the spring 19, and its locking surface 151 engages with the locking hole 161 of the locked portion 16. This reliably prevents the coupler 6 from falling off from the battery case 1 due to vibration or the like. In addition, in order to remove the coupler 6, the coupler 6 can be pulled out from the battery case 1 after separating the locking claw 15 from the locked portion 16 while expanding it with a finger against the spring 19.

FIG. 7 shows a fifth embodiment of the present invention, in which the locking hole 16 in the fourth embodiment is shown. A plate-shaped locked portion 16 having
Instead, it is characterized in that a locked portion 16 having a locking protrusion 162 that can be engaged with a locking claw 15 provided on the coupler 6 side is provided. This embodiment also provides the same effects as the fourth embodiment described above.

8 and 9 show a sixth embodiment of the present invention, and this embodiment is characterized in that the coupler 6 simultaneously supports a blade fuse 20 and a spare blade fuse 20'. . That is, this coupler 6 includes a main body part 21 that fits into the stepped part 2 of the battery case 1, and this main body part 21 has a guide groove that engages with the guide protrusion 3 of the battery case 1 as in the fifth embodiment. 7. Coupler terminal 8 connected to positive terminal 4 and negative terminal 5 of batch IJ B
9 and a locking claw 15 that can be engaged with the locked portion 16 of the battery case 1. A fuse holder 22 integrally formed on the upper surface of the main body 21 of the coupler 6 has a support hole into which the blade fuse 20 is inserted, and a pair of support claws that press and hold the end surface of the spare blade fuse 20'. 221 is provided. When the coupler 6 is attached to the battery case 1, both fuses 20.20
' is supported in a lying state along the top surface of the battery case 1.

According to this embodiment, not only can the actually used blade fuse 20 and the spare blade fuse 20' be held at the same time, but also because the fuses 20 and 20' protrude from the top surface of the battery case 1, it is possible to hold the coupler 6 easily. The fuse 20°20' can be replaced while it is attached.

Further, since both fuses 20 and 20' are supported along the upper surface of the battery case 1, the appearance is good and the height of the battery B does not become extremely high.

10 and 11 show a seventh embodiment of the present invention, and this embodiment is characterized in that three sides of the outer periphery of a spare blade fuse 20'' are supported by three support claws 222. Therefore, it is possible to obtain the same effects as the sixth embodiment with this embodiment as well.
