Description

[Detailed Description of the Invention] The present invention relates to a bicycle generator, and particularly relates to an improvement in the output terminal structure thereof.

Conventionally, the structure of this type of bicycle generator is as shown in Figs. 1 and 2, 1' is a roller that rotates in contact with the tire, and 2' is a magnet that rotates as the roller 1' rotates. The case body includes a rotor (not shown) and a stator 4' that generates an electromotive force due to the rotation of the rotor, and 5' is the case body 2'.
The lower case 5' is fixed by a method such as bending the open end of the case body 2' inward, and the lower case 6' has a protruding piece 6a' for caulking. In the first terminal cup formed, the protruding piece 6a' is disposed through the lower case 5', and the terminal plate 7' and the lug terminal 8' are disposed overlappingly on the lower case 5'. The protruding piece 6a' was caulked to fix the lower case 5', the terminal plate 7', and the lug terminal 8' together. Further, a spring 9' and one end of a second terminal cup 10' are contained in the first terminal cup 6', and the second terminal cup 10' is disposed so as to be movable in the upward and downward directions. , the terminal cup 8'
A lead wire 12' was soldered to the terminal for electrical connection.

However, according to the structure of the bicycle generator as described above, there are many parts that make up the output terminal section.
In addition, there is a caulking operation for fixing the lower case 5', the terminal plate 7', the lug terminal 8', and the first terminal cup 6' together, and for electrically connecting the lead wire 12' and the lug terminal 8'. This required complicated soldering work, resulting in very poor productivity. Also, when the second terminal cup 10' is pushed and the cord (not shown) is inserted into the through holes 6b' and 10a' formed in the first and second terminal cups, the second terminal cup 10' The first terminal cup 6' was caught, and the second terminal cup 10' could not be moved smoothly in the upward and downward directions.

Hereinafter, in order to eliminate the above-mentioned defects, the present invention has a spring fixing plate press-fitted into an insertion hole formed on the lower surface of the protruding part of the iron core constituting the stator, and a groove formed in the spring fixing plate. By inserting one end of the elastic terminal board inside the terminal board and placing the other end of the terminal board in the long hole of the lower resin case, the number of parts can be reduced and crimping and soldering work can be eliminated. The purpose is to improve productivity.

The present invention will be described with reference to drawings showing embodiments.

Note that an insertion hole 6b is provided at the tip of the protrusion 11a.
A flange 11d is formed to prevent the spring fixing plate 11 from coming off, and one end of the generating coil 7 is grounded to the case body 2, and the other end is connected to the spring fixing plate 1 as shown in FIGS.
It is electrically connected to the elastic terminal plate 13 via the lead wire 12 within the first groove 11b of the first groove 11b. Also 1

Next, the spring fixing plate 11 is attached to the lower surface of the stator 4 by press-fitting the protrusion 11a formed on the upper part of the spring fixing plate 11 into the insertion hole 6b formed in the protruding piece 6a of the iron core 6. sliding part 13a of
The output terminal structure has an output terminal structure in which the lower case 5 is attached to the lower end opening of the case body 2 so that the lower case 5 is disposed in the elongated hole 9 of the lower case 5. The output terminal section can be assembled.

As described above, the output terminal structure of the present invention has an insertion hole formed on the lower surface of the protrusion of the iron core constituting the stator, and a protrusion for press-fitting and fixing the lead wire and terminal plate into the insertion hole. A spring fixing plate formed with first and second grooves for arranging the insertion part is disposed on the lower surface of the protrusion, and an elastic terminal plate is disposed in the elongated hole formed in the lower case. The output terminal structure has a sliding part that is slidably arranged, so there is no need to swage the terminal board, lower case body, and terminal cup, which was done in the manufacturing process of conventional bicycle generators, or to swage the lead wires and lugs. It is possible to eliminate complicated work such as soldering work for electrically connecting terminals, which has the effect of improving the productivity of bicycle generators, and also significantly reduces the number of parts that make up the output terminal section. This has an extremely excellent practical effect of reducing manufacturing costs.
