Description

Coupler device for vehicle battery {A COUPLER FOR A CAR BATTERY}

The present invention relates to a battery coupler device suitable for a vehicle, in particular a motorcycle.

In addition to connecting one end of a harness to each of the positive terminal and the negative terminal of the battery, one coupler may be collectively connected to the positive terminal and the negative terminal.

For example, Japanese Unexamined Patent Application Publication No. 1-278236, a vehicle power supply apparatus, is shown in FIG. 1 of the publication, and a panel / box 1 has a regulator / rectifier 2, a fuse 3, and a starter relay. An electronic component such as (4) is inserted therein and the panel box 1 can be attached to the terminals 10 and 11 of the battery 9 with bolts 15 and 16 in this state. The wire harness for connecting the components of the power supply circuit is unnecessary, and is fixed integrally to the battery, thereby facilitating layout and improving aesthetics.

However, in the above-mentioned device, since an electronic component such as a starter relay 4 is fixed on the upper surface of the panel box 1 (opposite side of the battery mounting surface), the electronic component protrudes greatly from the battery. It is hard to say that the aesthetics can be improved. In addition, the individual components are not arranged in a space-efficient manner on the upper surface of the battery. Moreover, manufacture of a panel box is not easy.

Accordingly, an object of the present invention is to provide a coupler device having a simple structure and a compact waterproof function.

10 is a right side view of the coupler device and the battery according to the present invention, and shows a state in which the coupler device 30 is mounted on the battery 20. Since the spare main fuse 42 and the spare sub fuse 43 can be seen from these, the spare fuses 42 and 43 can be recognized even if the preservation inspector is on either side of the coupler apparatus 30 on either side.

Moreover, the upper protrusion height H of the coupler apparatus 30 is 15-18 mm, and when the height of the battery 20 is 75 mm, the total height can be accommodated about 90-93 mm.

The operation of the coupler device described above will be described next.

Fig. 11 is a circuit diagram of a vehicle and a coupler device according to the present invention, showing the contents of the coupler device 30, the surrounding harness and the device.

For example, to start the engine, the combination switch 21 is turned on, the brake switch is held, the stop switch 80 is turned on, and the start switch 81 is turned on.

Since the voltage of the battery 20 is applied to the coil 82 of the starter relay 35 through the main fuse 36 and the sub fuse 37, a suction action occurs in the coil 82 and the movable contact 83 is closed. Closed, the terminal (A) and the terminal (B) is connected.

Thus, the voltage of the battery 20 is applied to the starter motor 84, and the starter motor 84 starts to rotate.

At the same time, under the action of plug ignition mechanism (CDI) 85 the plug starts ignition and the engine starts to rotate. During operation, the alternator 86 generates power as the engine rotates, and this power generation can be sent to the battery 20 through the regulator / rectifier 23 and stored therein.

As described above, the coupler device 30 of the present invention collectively wires the starter relay 35, the main fuse 36, the sub fuse 37, and the internal wiring (harness).

And as is clear from FIG. 10, since the back (back cover 39) is the same surface as the side surface of the battery 20, the coupler apparatus 30 does not protrude sideways. In addition, the amount of protrusion upward from the battery 20 is also very small, and there is no obstacle locally projecting upward. Thus, the coupler device 30 of the present invention is quite compact.

In addition, as shown in FIG. 9, the terminals A-D were made waterproof. Since the terminals A to D of the starter relay, which are expected to have poor contact due to water or moisture, have a waterproof structure, the coupler device 30 can be used under some adverse conditions.

2 and 3, the spare fuses 42 and 43 are stored in positions visible from the outside. In general, the spare fuses 42 and 43 are stored in an inconspicuous position in the case. In this case, trouble is taken at the time of the fuse exchange. However, according to the present invention, since spare spares can be saved, the replacement of the fuses can be completed in a short time.

In addition, the coupler device of the present invention can be provided in a battery of a general vehicle such as a passenger car, a truck, in addition to a battery for a motorcycle.

Further, the waterproofing means described in claim 1 may be formed by the waterproofing jaws 74 and 75 and the waterproofing plug 76 of the present embodiment, and the connection portions between the terminals A to D and the harness are hardened with a waterproof resin. (The embodiment hardened by resin is mentioned later.) Any shape and a material may be used as long as it is a means which prevents water from entering into terminals A-D. In the embodiment, the fuse was two of main and sub, but three or more fuses may be used.

The spare fuse does not necessarily need to be seen from outside. This is because the spare fuse can be easily taken out by only opening the rear cover 39.

12-18 show the example which employ | adopted waterproof resin.

FIG. 12 is another embodiment of FIG. 5, and the same reference numerals are used for the same elements as in FIG. 5, but in this example, the arrangement of four terminals A, B, C, and D is changed.

That is, when the back cover of the coupler device is opened, the negative terminal female contact 51 and the positive terminal female contact 52 are disposed on the lower left and right sides, the sub-fuse arm contacts 53 and 54 and the main fuse female contact on the upper left side. (55, 56), on the right side you can see the female contacts 57A, 57B, 57C, 57D for connecting to the four terminals A, B, C, D of the starter relay, but the terminal C, The terminal D is arranged next to the terminal, and the terminal B is disposed at the farthest diagonal position.

As described in FIG. 11, the terminals A and B are in a power feeding circuit for driving the starter motor 54 by the battery 20, and are spaced apart as much as possible, thereby making it more difficult to short circuit.

FIG. 13 is a diagram in which the harness is added to the schematic diagram of FIG. 12, and the harness 61 directed from the female contact 57D to the stop switch, the harnesses 62 and 63 directed from the female contacts 54 and 56 to the combination switch, and the arm. Extends the harness 64 from the contact 57B to the starter motor, the harness 65 from the arm contact 51 to the earth, and connects the female contact 57C and the female contact 53 to the harness 66; 3 shows that the female contact 52, the female contact 57A, and the female contact 55 are connected to each other by the bus bar 91. As shown in FIG.

FIG. 14 is a cross-sectional view taken along line 14-14 of FIG. 12, and is an improved view of FIG.

In FIG. 9, the starter relay 35 is surrounded by the relay terminal box 72, and the sealing materials 71 and 73 block water from the outside toward the terminals A and C (from right to left in FIG. 9). In addition, the waterproof jaw 75 and the waterproof plug 76 adopt a waterproof structure that blocks water toward the terminals A and C (from left to right in FIG. 9).

However, FIG. 14 shows that the relay terminal box 72, the sealing materials 71 and 73, the waterproof jaw 75 and the waterproof plug 76 are closed. In order to abolish, the bottom portion of the terminals C and A of the starter relay 93 is waterproofed with a resin mold 92. In addition, improvements were also made in connection structure of the bus bar 91 which will be described later.

Fig. 15 is an exploded view of a starter relay according to another embodiment. The starter relay 93 protrudes the terminals a, b, c, d on one end of the box 93a, and their terminals a, b. , c, d are surrounded by a large rectangular frame 93b, and the inside of the rectangular frame 93b is partitioned into four chambers by a partition frame 93c, and the terminals a, b, c, d are accommodated, and terminals A-D are inserted from above toward the terminals a, b, c, d of each chamber.

16A to 16C are diagrams for explaining the procedure for attaching a terminal to a starter relay.

(a) is a figure corresponding to the arrow of 16a-16a of FIG. 15, and can mount terminal B, D as a target from the top from the top. The same applies to terminals A and C, but their description is omitted.

In (b), the terminal B is fixed to the terminal b by the inversion 94 and the terminal D is fixed to the terminal d by the inversion 94.

In (c), resin is introduced from above and the bottoms of the terminals B and D are fixed. The cured product becomes the resin mold 92. By fixing with the resin mold 92, it is possible to eliminate the defective state in which water is infiltrated between the terminals a to d and this water induces a short circuit.

Fig. 17 is a view of the arrow 17 in Fig. 16B, and shows a projection 96 facing the inner wall of the rectangular frame 93b at the bottom of the terminal B in the lower right of the drawing. The projection 96 serves to position the terminal B at the bottom of the terminal B, to stabilize the inversion, and to prevent lateral shift when the resin is introduced. The same applies to the other terminals A, C, and D.

Moreover, the partition frame 93c is provided in order to change the shape of each thread as a countermeasure against insertion error of the terminals A-D. Therefore, mounting error can be prevented beforehand, and work efficiency improves. However, in the case where the mounting of the terminals A to D is automated, there is no need to worry about the occurrence of an error. Therefore, the partition frame 93c may be abolished and the cost may be reduced by using only the rectangular frame 93b.

Fig. 18 is an exploded perspective view of a busbar according to another embodiment, in which the female contact 57A facing the female contact 52 and the terminal A is inserted into one end of the connection holding portions 97 and 97, respectively. By inserting the bus bar 91 at the other end of the connection holding portions 97 and 97, the bus bar 91 can be easily connected to the female contacts 52 and 57A.
