Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a float for night fishing, for example, a float powered by an alkali metal battery or mercury battery and using a small light bulb, light emitting diode, or the like.

Conventionally, electronic floats for night fishing have been known, for example, as shown in FIG. 1, which are lighted or emit light by connecting a miniature light bulb or light emitting diode to a small alkali metal battery.

That is, a battery 2 and a light emitting diode 3 are connected inside the float body 1 via lead wires 4.

Note that 5 is a resistor, 6 is an insulating sleeve for preventing short circuits, and 7 is a connecting portion.

A backing 8 is fitted into the float main body 1, and a cap body 9 is screwed into the backing 8 to seal it.

At this time, the battery 2 is pressed against and comes into contact with the connecting portion 7 by a spring 10 provided in the cap body 9, so that the light emitting diode 3 emits light.

Note that 11 is a thread hole.

In the electronic float having such a configuration, the battery 2 is connected to the connection part 7.
Since the light emitting diode 3 emits light continuously by contacting with the water, the battery will be exhausted quickly (and since the water surface becomes bright, fish with photophilic tendencies will gather near the bright water surface, making it unsuitable for fishing). However, when several anglers fish at night next to each other, they exhibit the same luminescent state, making it difficult to distinguish between one's own float and others.

In addition, there are some devices, such as the technology described in Japanese Utility Model Application Publication No. 53-39785, that have a built-in rechargeable battery to prevent battery consumption, but since they emit light continuously, they can be used for photophilic fish as mentioned above. It had drawbacks such as being unsuitable for

The present invention has been made in view of the above points, and includes two or more light emitting diodes or miniature light bulbs housed inside the tip of the float body, and connecting terminals such as pins from the light emitting diodes etc. to a terminal board. The connection terminal and the output terminal are an electronic float consisting of a structure in which a battery and a time constant circuit are connected and housed in a capsule, and an output terminal of the time constant circuit is derived from the capsule. When inserted, they fit together like a pin and a jack and become electrically conductive.

An example using a light emitting diode will be explained below.

As shown in FIG. 2, light emitting diodes 22 and 23 are housed at the tip of the float body 21, and the light emitting diodes 22 and 23 are attached to a terminal plate 25 via a lead wire 24.
connection terminals 26.

The connection terminal 26 uses a terminal connected by fitting, such as a pin or a jack.

On the other hand, the time constant circuit 27 is connected to the battery 28 and the capsule 2
9 and from the end surface of the capsule 29 the connection terminal 2
Three output terminals 30 matching 6 are derived.

The output terminal 30 of the capsule 29 is inserted into the connection terminal 26 to establish electrical continuity between the battery 28 and the light emitting diodes 22 and 23.

Then, a cap body 32 having a spring 31 is fitted into the open end of the float main body 21 by screwing or the like, and the cap body 32 is sealed.

At this time, a backing 33 such as a rubber ring may be used if necessary.

As the time constant circuit, for example, one shown in FIG. 3 is used.

In other words, in this circuit, capacitors C1 and C2 and resistor R
By selecting appropriate constants I to R4, various discharge time constants can be obtained.

In this circuit diagram, the ■C terminal is the light emitting diode 22.
and 23, which is a common terminal for intermittent and continuous lighting, ea terminal is a terminal for intermittent flashing, and eb
The terminal is a terminal that lights up continuously.

Therefore, one of the light emitting diodes connected to the time constant circuit 27 lights up continuously and the other one flashes intermittently.

In the electronic float constructed as described above, replacing the capsule incorporating the time constant circuit and battery is very simple, as the operation is simply to remove the capsule and insert another capsule.

Furthermore, by incorporating time constant circuits with different time constants, it is possible to obtain electronic floats that exhibit blinking states of various periods, which makes it extremely easy to distinguish one float from another.

In the above embodiment, the time constant circuit 27 and the battery 28 are housed in one capsule 29.
As shown in the figure, the time constant circuit 37 is housed in one end surface formed by a partition 42 provided in one capsule 39, and the output terminal 40 is led out from the one end surface.

Further, the time constant circuit 37 and the battery 38 are provided in the partition 42.
A contact portion 41 is provided, and the battery 38 housed on the other end surface generated by the partition 42 is accommodated in a state in contact with the contact portion 41, and the open end of the battery accommodating portion is screwed in, etc. The structure sealed with the lid 43 has the advantage that the battery 38, which is often replaced due to wear and tear, can be replaced very easily.
