Description

[Detailed description of the invention] The present invention relates to a switch device such as an emergency switch used in outboard motors, etc., and in particular, has two sets of built-in contacts to stop two outboard motors at the same time. This invention relates to a switch device that allows the user to switch the switch.

An emergency switch, which is generally used in outboard motors, is crimped onto the casing and has a plug with a string such as a rope that turns the built-in contact OFF. Pulling the string removes the plug and turns the contact ON. It is of structure.

Therefore, when installing two outboard motors, conventionally,
One switch was attached to each outboard motor, and by operating this switch, the outboard motor engine was stopped. This increases the cost of the switch and requires two remote control strings, such as ropes, which can sometimes get tangled and become cumbersome to manage. Further, even when the string is used by being tied to the operator's body, there are still problems in that it is cumbersome and difficult to operate.

The present invention was developed in view of the current state of the art, and its purpose is to operate two outboard motors using one switch device, that is, one remote control string. We are trying to provide a switch device that can stop both at the same time.

The feature of this invention is that two sets of contact mechanisms are built into the casing, and by pulling one string tied to the plug, the plug is removed and both contacts are turned on simultaneously. .

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIGS. 1 and 2.

FIG. 1 shows the entire switch device of the present invention, and FIG. 2 shows the relationship between the first and second contact members and the first and second movable contact pieces.

In the figure, reference numeral 1 denotes a casing, which has a plug crimping part 2 made of an assembly nut at its upper end, a guide hole 3 bored in the vertical direction approximately in the center, and an interior in which a contact mechanism is built-in. The lower part of the space is closed off by a base 4 which essentially forms part of the casing. A blind hole 5 is bored approximately in the center of the inner surface of the base 4. Reference numeral 6 denotes a rod-shaped insulating shaft, which is made of, for example, plastic resin, and is provided with downward protrusions 7, 7 extending from side to side at approximately the middle portion of the shaft. The upper portions thereof are inserted into the blind holes 5 of No. 4 and the guide holes 3 of the casing 1, respectively, and are movable up and down. In this case, a guide is also provided in the blind hole 5 to prevent the shaft 6 from rotating.
Reference numerals 8 and 8' denote first contact members disposed as a pair on the left and right inside the casing, and in the case of this embodiment, the base 4
The contact portions 8a, 8'a are horizontally bent inward to face the intermediate portion of the shaft 6. Reference numerals 9 and 9' designate a pair of second contact members disposed in the front and rear of the casing, and in this case as well, they are implanted in the base 4, and the contact parts 9a and 9'a are arranged horizontally on the inside. It is bent so that it faces slightly above the intermediate portion of the shaft 6.
That is, the contact portions 9a, 9'a are positioned higher than the contact portions 8a, 8'a of the first contact members 8, 8'. And each of these contact members 8,
Lead wires 10 are connected to the portions 8', 9, and 9' that protrude from the bottom surface of the base. Reference numeral 11 denotes a cylindrical insulating collar, which is formed into a rectangular cylindrical shape from, for example, plastic resin, and its lower end is connected to a hole 1 corresponding to the approximate center of the base 4 following the blind hole 5.
2 is fitted and fixed. The length is such that the lower half of the shaft 6 is inserted. A first coil spring 13 is installed on the outside of this collar 11.
A second coil spring 14 is fitted to the shaft 6 inside the collar 11.
A first movable contact piece 15 having a through hole 15a in the center is fitted into the upper part of the collar 11 so as to be movable up and down, and the first coil spring 1
At the same time as the shaft 3 is elastically biased upward by the shaft 6, its upper surface is brought into contact with and pressed against the downwardly directed left and right protrusions 7, 7 of the shaft 6. Therefore, when the entire shaft moves upward, the left and right portions of the movable contact piece 15 come into contact with the contact portions 8a, 8'a of the first contact members 8, 8' from below. . In other words, the contacts are turned on. Reference numeral 16 denotes a second movable contact piece, which is fitted onto the shaft 6 near the protrusions 7, 7 through a through hole 16a bored in the center, and is elastically biased upward by the second coil spring 14. The protrusions 7, 7 are seated on the lower surfaces of their proximal ends.
Therefore, as described above, when the entire shaft moves upward, the left and right portions of the movable contact piece 16 come into contact with the contact portions 9a, 9'a of the second contact members 9, 9' from below. It's getting old. In other words, the contacts are turned on. Note that here, the distance between the contact portions 8a, 8'a of the first contact members 8, 8' and the first movable contact piece 15 is _d1 , and the distance between the second contact members 9, 9'
When the distance between the contact portions 9a, 9'a and the second movable contact piece 16 is _d2 , the relationship is _d2 > _d1 . By setting d ₂ > d ₁ in this way, after the first contact is turned ON, the shaft 6 is further displaced upward to turn the second contact ON, and both contacts are turned ON.
will be ensured. That is, both contacts are securely connected by the elastic force of the spring 13 or 14.
The ON state can be obtained.

Reference numeral 17 denotes a plug to which a string 18 for remote control such as a rope is tied, which is crimped to the crimp portion 2 of the casing 1, and in this state is inserted into the casing guide hole 3 of the shaft 6 housed in the casing. The upper tip 6a of the coil spring 6a is pressed against the elastic biasing forces of both the first and second coil springs 13 and 14. In this state, each movable contact piece 1
5, 16 are corresponding contact members 8, 8', 9,
It is spaced apart from the contact portions 8a, 8'a, 9a, and 9'a of 9', and the contacts are in an OFF state.

In the above configuration, when the string 18 is pulled, the plug 17 comes off from the crimp part 2 of the casing 1;
The shaft 6 inside the casing is pushed upward by both the first and second coil springs 13, 14, and the first movable contact piece 15 is pushed up by the first contact member 8,
At the same time, the second movable contact piece 16 contacts the contact portions 9a, 9'a of the second contact members 9, 9'. That is, by pulling one string 18 once, the operator can turn on both contacts at the same time. Then, if the plug 17 is crimped to the crimping part 2 of the casing 1,
The shaft 6 is pushed down, and contrary to the above, both contacts can be turned OFF at the same time.

Note that the string 18 of the plug 17 is not limited to the above-mentioned rope, but may be any other material that transmits the pulling force of the operator, and may include, for example, a chain, wire, or other similar items. In addition, in order to make the casing 1 waterproof, it is preferable that the casing 1 has a sealed structure when the plug 17 is fitted therein.

As explained above, according to the switch device of the present invention, two sets of contact mechanisms that turn ON and OFF are built into the casing, so it is possible to stop the engines of two outboard motors with one device. can.
Therefore, it is possible to reduce the cost of the switch, and at the same time, since only one cord is required for remote control,
For management purposes, the two strings get tangled like in the past.
It will no longer be a hassle. In other words, there is an advantage that it becomes extremely easy to organize the strings. Furthermore, even when the operator uses a string tied to his or her body, a single string is advantageous in that it is not cumbersome and is extremely easy to operate.
