The starter magnetic switch is activated, which electrically connects the starter motor to the battery and starts the engine.

The starter magnetic switch is usually provided independently, and is placed at an appropriate position, such as between the carburetor and the air cleaner, or behind the air cleaner, so that it does not interfere with engine accessories, with a vibration isolating member interposed therebetween. There is.

"Problems to be Solved by the Invention" By the way, the starter magnetic switch is located at a location where various engine accessories are arranged in a complicated manner, for example,
If the capacity or arrangement of engine accessories such as the air cleaner changes due to design changes, etc., ensure space for placing the starter magnetic switch and wiring space for the starter magnetic switch. It was often difficult to do so in cases where it could not be done without.

Therefore, the inventors of the present invention attempted to solve the above problem by providing a recess in the battery casing and integrally incorporating the starter magnetic switch into this recess.

However, when trying to put the above idea into practice, it became clear that there were various problems that needed to be solved. In other words, in order to incorporate the starter magnetic switch into the battery, the switch itself must be made smaller, and the problem is how to deal with this, and how to fix the starter magnetic switch to the battery. It is.

A supporting piece extending outward from the opposite side of the battery is fastened to the negative terminal of the battery, and the swinging piece is attracted to a part of the battery that is fastened to the terminal and the solenoid. The two parts are not on the same plane, but are arranged in a staggered manner, keeping them almost parallel to each other.

"Embodiment" An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

Fig. 1 is an exploded perspective view of the battery and the mater magnetic switch that is integrally assembled on top of the battery, Fig. 2 is a vertical cross-sectional view of the main parts 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 in opposite directions from both ends of the switch 2, and these terminals 5a and 5b are fixed to electrode terminals 7a and 7b of the battery 1 with bolts 6, so that the switch 2 can be operated. 2 is fixed to battery 1. That is, terminals 5a and 5b are connected to switch 2.
It has the function of fixing the battery to the battery 1.

Here, the main circuit (starter motor drive circuit) located on the left side of the switch 2 in FIGS. 1 and 2.
When the + side terminal 5a for configuration is fixed to the + side terminal 7a of the battery 1, the + side terminal 5a of the battery 1 is connected to the + side terminal 7a of the battery 1.
electrically connected directly to the side. 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, terminal 5b
is a so-called dummy terminal (supporting piece) that functions only to fix the switch 2.

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 the cable 9 is connected to the starter motor M, and the other end of the cable 9 is connected to the 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. 2, the switch 2 includes a casing (switch case) 21 and a casing 2.
The solenoid 22 (two solenoids are arranged in this figure, but the design can be changed as appropriate) is fixed to the bottom plate of the terminal 5a, and the conductive solenoid 22 is riveted to the inner end of the casing of the terminal 5a. An arm 23 made of a magnetic material and a non-magnetic material (for example, phosphor bronze), a movable electric contact 24 fixed to the lower surface of the tip of this arm 23, and the terminal opposite to this movable electric contact 24. The basic configuration consists of a fixed electrical contact 25 provided on the top of the 8.

The arm 23 constitutes a swing piece 26 together with the terminal 5a, and when the solenoid 22 is excited, an armature 23a made of a magnetic material attached to the lower surface is attracted by the solenoid 22. As a result, it is attracted to the lower position, and when the solenoid 22 is de-energized, it returns to the upper position by its own elastic action. Note that FIG. 2 shows a state in which the solenoid 22 is energized and the arm 23 is in the downward position. Further, a stepped portion 23b is provided near the portion of the arm 23 that is fixed to the terminal 5a, so that the portion of the arm 23 that is attracted and biased by the solenoid 22 is attached to the portion that is fixed to the terminal 5a. On the other hand, they are arranged not on the same plane but in a manner that they are shifted so as to approach the upper surface of the casing 21 while remaining parallel to each other.

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 and 28B are provided with a convex portion on one of the mutually abutting portions, and a concave portion corresponding to the convex portion on the other side, so that the two are fitted in a concave-convex manner. In addition, both inner case halves 28
The terminals 5a, 5b, 8, 11 are connected between A and 28B.
are clamped and fixed with a sealing material 31 interposed between them. The inner case 28 configured as described above is covered by the outer case 27 which is 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 time, 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. In this case, the push spring 32 normally holds the electrical contacts 24 of the arm 23 so as not to touch the contacts 25, and while the solenoid 22 is energized, the electrical contacts 24, 25
This allows them to be in the closed position.

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, the starter motor drive circuit is closed, starter motor M is electrically connected to battery 1, and the engine is started. Note that when the press of the starter button is released after starting the engine, the excitation of the solenoid 22 is released, the electrical contacts 24 and 25 are opened, and the power to the starter motor M 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
In this case, one end of the swing piece 26 having the movable electric contact 24 is extended outward from the casing 21, and the support piece 5b is extended outward from the opposite side of the part of the casing 21 from which the swing piece 26 extends. Since the outwardly extending ends of the rocking piece 26 and the supporting piece 5b are bolted to the battery terminals 7a and 7b, respectively, special parts for fixing the switch 2 to the battery 1, such as The starter magnetic switch can be fixed without providing a female thread.

In addition, the starter magnetic switch 2 mentioned above
In this case, the swinging piece 26 that performs the fixing function is made of a conductive material, and the movable electrical contact 24 is directly electrically connected to the battery terminal 5a by the swinging piece 26, so it is not possible to use a cable. Compared to the conventional one, which was connected by
The voltage drop can be reduced, the number of electrical contacts can be reduced, and problems such as kinking of the cord do not occur, and reliability can be improved.

Furthermore, in the starter magnetic switch described above, the arm 23 is provided with a stepped portion 23b, and the portion of the arm 23 that is attracted and biased by the solenoid 22 is not on the same plane as the terminal 5a but on the upper surface of the casing 21. Since the starter magnetic switch 2 is arranged so as to be offset from each other, the starter magnetic switch 2 can be made more compact in the height direction than when a straight arm is used. By the way,
When using a straight-shaped arm, the terminal 5a must be arranged at the same height as the top surface of the solenoid 22, and as a result, the top surface of the casing 21 is free from interference with the rivet connecting the arm 23 and the terminal 5a. In order to avoid this, the starter magnetic switch 2 must be shifted upwards, which results in an increase in the overall height of the starter magnetic switch 2.

Further, FIG. 4 shows a modification of the swinging piece 26. In this example, arm 23 and terminal 5
The connecting tool 40 that connects a is made into an elongated one,
A terminal 5a is fixed to its lower end, and an arm 23 is fixed to its upper end. Even if such a swing piece 26 is used, the starter magnetic switch 2
can be made more compact in the height direction.

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

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

(a) One end of the rocking piece having the movable electrical contact is extended to the outside of the switch case and fastened to the battery terminal, and the support piece is attached to the opposite side of the switch case from where the rocking piece extends. Since it extends outward and is fastened to the battery terminal on the other side, it is possible to fix the starter magnetic switch without having to provide a special part, such as a female thread, to fix the switch to the battery. Become.

(b) Also, since the rocking piece that performs the fixing function is made of a conductive material and the movable electrical contact is directly electrically connected to the battery terminal by this rocking piece, it is not possible to use a cable. Compared to conventional connections, the voltage drop can be reduced by eliminating cables, and the number of electrical contacts can be reduced, and problems such as kinking of the cord do not occur, improving reliability. can be achieved.

(c) Furthermore, the part of the rocking piece that is attracted and deflected by the solenoid is not on the same plane as the part of the rocking piece that is connected to the battery terminal, but is offset from the part of the rocking piece that is connected to the battery terminal. Compared to using a moving piece, the starter magnetic switch can be made more compact in the height direction, which is particularly advantageous when it is incorporated into a battery.
