Description

[Detailed Description of the Invention] The present invention relates to a battery holding device such as an electric float that uses a light emitting diode as a light source.

Conventional battery holding devices of this type have a cylindrical outer case as one electrode, a protrusion protruding from the end face of the outer case as the other electrode, a battery holding part, and a side surface of the battery outer case. There is a structure in which one conductor has an elastic contact piece at its end that contacts, and the other conductor has an elastic contact piece at its end that contacts the side surface of the convex part of the battery. , one conductor is placed in contact with the side of the battery's outer case, so structurally speaking, one conductor must operate outside the battery's outer case, resulting in a structural becomes more complex and larger in shape.

Furthermore, since the conductor on one side of the protrusion of the battery is brought into contact with the side surface of the protrusion, there is a problem that if the length of the protrusion is short, the conductor will not come into contact with it.

The present invention aims to provide a battery holding device that can hold any battery regardless of whether the protrusion of the battery has a long or short length. I will explain based on this.

In Fig. 1, reference numeral 1 denotes a cylindrical upper case constituting the float body, and this upper case 1 has a narrow top part 2 formed at the upper part, and this top part 2 houses a light emitting diode 3 that serves as a light source. are doing.

4 is a battery holding part, and this battery holding part 4 is attached to the upper case 1.
The upper end opening of a cylindrical lower case 5 is press-fitted onto the outer periphery of the battery holding portion 4 .

6 is a slender rod-shaped lithium battery, and this lithium battery 6
is housed in the lower case 5 and is inserted and fitted into the lower part of the battery holding part 4.

Further, the battery holding portion 4 has two conductors connected to the lithium battery 6, and the conductors and the light emitting diode 3 are electrically connected via lead wires 7, 7'.

Next, the structure of the battery holding part 4 will be explained based on FIGS. 2 and 3.

Reference numeral 8 denotes a holding cylinder having a cylindrical shape and having a stepped portion 9 that divides the inside into upper and lower parts, and this holding cylinder 8 is made of an insulating material.

10 is one conductor made of a compression coil spring, and this conductor 10 extends its winding end perpendicularly in the up and down direction.
The upper part serves as a connection end 10a to the lead wire 1', and the lower part serves as a contact end 10b to the protrusion 6a of the lithium battery 6.

A through hole 11 through which the contact end 10b passes and a hole 12 into which the convex portion 6a of the lithium battery 6 is inserted are provided in the center of the stepped portion 9 of the holding cylinder 8.

Reference numeral 13 denotes the other conductor made of a compression coil spring. This conductor 13 is wound with a diameter approximately equal to the outer diameter of the cylindrical outer case 6b constituting the lithium battery 6, and is placed below the stepped portion of the holding cylinder 8. It is housed and held on the outside of the formed protrusion 14.

The other conductor 13 that has been wound is extended vertically upward at the end of its winding to form a connection end 13a with the lead wire 7,
In addition, this connecting end 13a extends upward through a through hole 15 provided in the step portion 9.

16 is a lid installed at the upper end opening of the holding cylinder 8;
6 restricts the upward movement of one conductor 10 so that the contact end 10b of the conductor 10 is spring-biased downward, and the connecting end 10a of the two-way electric body 10.13.
, 13a, the connection ends 10a,
Through-holes 17 and 18 through which the passages 13a pass are formed at intervals.

The lower part of the conductor 13 made of the other compression coil spring comes into contact with the upper end surface of the outer case 6b of the lithium battery 6 due to the biasing force of the compression coil spring when the battery is attached.

In the above configuration, when holding the lithium battery 6 in the battery holding part 4, the lithium battery 6 is pushed in from below the holding cylinder 8.

As a result, in the lithium battery 6, the upper surface of the convex portion 6a serving as a cathode is brought into contact with the contact end 10 b Ka of one conductor 10 .

In this case, the contact 1iob of one of the conductors 10 made of a compression coil spring expands and contracts in the vertical direction according to the length of the convex portion 6a, and reliably contacts the convex portion 6a.

On the other hand, the outer case 6b of the lithium battery 6, which serves as an anode, has a shoulder portion on the upper end surface of the other conductor 13, which is made of a compression coil spring.
touches the bottom of the

This forms a lighting circuit for the light emitting diode 3.

In order to prevent the lithium-type object 6 from being removed, an annular protruding rib 19 is provided on the inner wall of the lower part of the holding cylinder 8, and an annular groove 2 is provided between the protruding rib 19 and the upper part of the outer case 6b of the lithium battery 6.
This is done by elastically fitting the two.

Although the above embodiment has been described as a holding device for an electric float, this battery holding device can also be applied as a battery holding device for a light-emitting lure, a light-emitting squid needle, a rod tip light, etc.

As described above, according to the present invention, the battery holding part that holds the cylindrical battery has a conductor that contacts the end surface of the battery's outer case, and a conductor that is biased in a direction that constantly contacts the top surface of the convex part of the battery. Since a conductor is provided, the biasing force of the conductor causes
Regardless of whether the length of the protrusion protruding from the end face of the outer case is long or short, contact is ensured, and as a result, any battery can be held.

The conductor that comes into contact with the end surface of the outer case of the battery is
In order to make contact with the end surface of the convex side of the battery's exterior case, the structure is such that a conductor is extended from the convex side of the battery along the side of the battery, and this conductor is connected to the bottom surface of the battery. This is simpler than a device in which the device is brought into contact with the device, and as a result, it can be provided at a low cost.
