"Embodiment" An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

Fig. 1 is an exploded perspective view of the battery and the starter magnetic switch that is integrally assembled on top of the battery, Fig. 2 is a vertical cross-sectional view of the main part showing the state where the starter magnetic switch is assembled into the battery, and Fig. 3 is FIG. 3 is a sectional view taken along the - line in FIG. 2;

In these figures, the reference numeral 1 indicates a battery installed in a vehicle such as a motorcycle, and the reference numeral 2 indicates a starter magnetic switch (hereinafter simply referred to as a switch).

A recess 4 having a rectangular cross section in accordance with the external shape of the switch 2 is provided on one side of the upper part of the lid 3 of the battery casing, and the switch 2 is installed in this recess 4. Terminals 5a and 5b are provided extending outward from both ends of the switch 2, and by fixing these terminals 5a and 5b to electrode terminals 7a and 7b of the battery 1 with bolts 6, the switch 2 is connected to the battery 1. It is fixed at 1. That is, the terminals 5a and 5b function to fix the switch 2 to the battery 1.

Here, the + side terminal 5a for the main circuit configuration located on the left side in FIGS. 1 and 2 of the switch 2 is directly connected to the + side of the battery 1 when it is fixed to the + side terminal 7a of the battery 1. electrically connected.
On the other hand, the terminal 5b located on the right side of the switch 2 in the figure is a metal support piece that is insulated and supported by the case, and does not constitute an electrical contact. That is, the terminal 5b serves only to fix the switch 2, and is a dummy terminal (support piece).

In this switch 2, the - side terminal 8 constituting the main circuit is provided so as to protrude outward from the side of the switch 2 with an opening angle of 90 degrees with respect to the dummy terminal 5b. And this terminal 8
One end of cable 9 is connected to , and the other end of cable 9 is connected to starter motor M.

Further, one end of the cable 10 is connected to the negative terminal 7b of the battery 1 by the bolt 6, and the switch 2 is connected to the negative terminal 7b of the battery 1.
The other end of this cable 10 is connected to the starting motor M. Reference numeral 11 denotes a terminal protruding outward from the side of the switch 2. The inner end of the terminal 11 is electrically connected to a solenoid 22 built into the switch 2, and the outer end thereof is electrically connected to a solenoid 22 built into the switch 2. is electrically connected to the cell button via a cable (not shown). Further, 12 is a fuse interposed in the main circuit, and 13 is a spare fuse.

Next, the switch 2 will be explained in detail. As shown in FIG. The number can be changed as appropriate) and
an arm 23 made of a conductive and non-magnetic material (for example phosphor bronze) riveted to the inner end of the casing of the terminal 5a;
The basic structure consists of an electrical contact 24 fixed to the lower surface of the tip of the arm 23, and an electrical contact 25 provided on the terminal 8 to face the electrical contact 24. The arm 23 constitutes a swinging piece 26 together with the terminal 5a, and when the solenoid 22 is excited, the solenoid 2
The armature 23a made of a magnetic material attached to the lower surface of the solenoid 2 is attracted to the lower position, and on the other hand, when the solenoid 22 is de-energized, it is moved upward by its own elastic action. It returns to its position. Note that FIG. 2 shows a state in which the solenoid 22 is energized and the arm 23 is in the downward position.

The casing 21 has a double structure consisting of an outer case 27 and an inner case 28. The inner case 28 is made of synthetic resin and has a structure that is divided into upper and lower halves as shown in FIG. Both inner case halves 28
A, 28B have a convex portion 29 on one side of the mutually abutting portions, and a concave portion 3 corresponding to the convex portion 29 on the other side.
0 are respectively provided, so that the two are fitted in a concave and convex manner. Further, the terminals 5a, 5 are provided between the inner case halves 28A, 28B.
b, 8, and 11 are sandwiched and fixed with a sealing material 31 interposed therebetween. and,
The inner case 28 configured as described above is covered by the outer case 27 integrally molded from a synthetic resin material.

Further, 32 is a tension spring, and this spring 32 assists the suction when the solenoid 22 is energized and attracts the arm 23 downward. During this period, the arm 23 is pulled downward to hold the electrical contacts 24 and 25 in the closed position. It is also conceivable that this 32 is a push spring. That is, in this case, the push spring 32 normally holds the electrical contact 24 of the arm 23 so that it does not touch the contact 25, and keeps the electrical contacts 24 and 25 in the closed position while the solenoid 22 is energized. It is something that is allowed to happen.

Next, the operation of the starter magnetic switch 2 will be explained.

When starting the engine, after closing the main switch (not shown), the solenoid 22 in the switch 2 is energized by operating the cell button.
By energizing the solenoid 22, the arm 23
is sucked downward as shown in FIG. 2, causing the electrical contacts 24 and 25 to close. As a result, starter motor M is electrically connected to battery 1, and the engine is started. Note that when the press of the cell button is released after starting the engine, the excitation of the solenoid 22 is released and the electric contacts 24 and 25 open, and the cell motor M
Power is cut off.

In addition, the starter magnetic switch 2 mentioned above
Since the battery casing has a recess 4 and is assembled into the recess 4, there is no need to secure a special space for installing the starter magnetic switch 2 in addition to the space for arranging the battery. Accordingly, a wider space can be taken up for the arrangement of other engine accessories, which is advantageous in terms of layout of these parts.

In addition, the starter magnetic switch 2 mentioned above
According to the above, the inner case 28 is divided into two parts, and the two inner case halves 28A and 28B are divided into two parts.
The two halves 28
Since the terminals 5a, 5b, 8, and 11 are sandwiched between A and 28B, it is easy to assemble the terminals 5a, 5b, etc. in a desired state, that is, in a state in which one end thereof protrudes from the case.

Further, the inner case 28 assembled as described above is covered by the outer case 27 integrally molded from a synthetic resin material, and a sealing material 31 is interposed between the inner case 28 and the terminals 5a, 5b, etc. Since it is equipped with a protective cover, it is possible to ensure excellent waterproof and dustproof properties.

Furthermore, since the terminals 5a and 5b are fixed to the electrode terminals of the battery, the battery 1
There is no need to provide a special part such as a female threaded part for fixing the switch 2 to the battery 1, and the structure of the battery 1 can be simplified accordingly. Furthermore, in the starter magnetic switch 2 described above, the terminal 5a that performs the fixing function is electrically connected to the internal electrical contact 24, and this terminal 5a is directly fixed to the electrode terminal of the battery 1. Compared to the conventional type that was connected, the voltage drop can be reduced by eliminating the cable.
Moreover, since the number of electrical contacts is reduced and problems such as kinking of the cord do not occur, reliability can be improved.

Note that the recess 4 for incorporating the switch 2 is
It does not necessarily need to be provided on the lid 3 of the battery as in the above embodiment, but may be provided on the casing body of the battery.

"Effects of the Invention" As explained above, the present invention provides the following excellent effects.

(a) A swing piece and a support piece are held between both inner case halves with one end thereof protruding outward, and are covered from the outside with an outer case integrally molded from synthetic resin. With this structure, the swing piece and the support piece can be firmly fixed to the starter magnetic switch main body side. Therefore, by fixing the protruding tips of these rocking pieces and support pieces to the battery, it is possible to firmly fix the starter magnetic switch to the battery.

(b) Furthermore, as mentioned above, since the casing has a double structure and the outer case is integrally molded from synthetic resin, it has excellent waterproof and dustproof properties.

(c) A rocking piece is electrically connected to the internal electrical contact, and the electrical contact can be connected to the battery electrode simply by fixing the outwardly protruding end of the rocking piece to the battery electrode terminal. This makes it possible to reduce voltage drop and improve reliability compared to conventional electrical connections using cables.

(d) In addition, if the inner case halves are constructed to fit into each other in a concave and convex manner, the work of assembling the swinging piece and the supporting piece to the inner case becomes easy.

(e) Furthermore, if a sealing material is interposed between the inner case, the rocking piece, and the support piece, rainwater and dust will be transmitted along the outer periphery of the rocking piece and the support piece, and the starter magnetic switch will be damaged. It can prevent intrusion into the interior and further improve waterproof and dustproof properties.
