Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a block dynamo that integrates a dynamo and a headlight case.

(b) Prior Art A block dynamo of this type as shown in FIG. 2 is known. That is, in FIG. 2, 1' is a dynamo, 24 is a protruding shaft protruding from the body of this dynamo 1', and the headlamp case 6' then inserts the protruding shaft 24 into the rear loose insertion hole 25 of the case 8'.
Loosely insert the slide washer 26 and the elastic body 2.
7 and, by inserting the base end 28a of the lead plate 28 that contacts the tail terminal of the internal light bulb 15' into the protruding shaft 24 and fixing it with the nut 29, the headlamp case 6' is fixed to the dynamo. 1', the protruding shaft 24 can slide vertically and horizontally within the movement range within the rear loose insertion hole 25. Sho 30
1 is a spare light bulb held between the tip of the lead plate 28 and the inner surface of the headlamp case 8', and 31 is a power supply lead wire electrically connected to the peripheral terminal of the light bulb 15'.
However, according to such a conventional example, since the lead plate 28 is directly attached to the protruding shaft 24, the nut 29 may become loose or the headlight case 8'
If the lead plate 28 is slid excessively, there will be looseness in the installation condition of the lead plate 28, and the lead plate 28 will
There was a fear that the terminal would not come into contact with the 5' tail terminal properly, resulting in poor conduction.

(c) Purpose of the invention This invention prevents electrical conduction failure between the lead plate and the bulb by fixing the lead plate to the headlamp case, and also prevents the connection between the lead plate and the mounting shaft. This prevents contact failure from occurring, and thereby prevents energization failure from occurring no matter how the headlamp case is slid.

(d) Structure of the invention The block dynamo of the present invention is a dynamo with a headlamp case slidably integrated into the dynamo, in which the lead plate of the light bulb housed in the headlamp case is attached to the headlamp case, and the headlamp case is slidably integrated into the dynamo. A spherical contact surface formed at the base end of the lead plate is pressed against the tip of a mounting shaft that rotatably supports the headlamp case, thereby electrically connecting the lead plate and the mounting shaft. The structure is such that even if the headlight case is slid up and down and left and right, the electrical connections between the light bulb and the lead plate, and between the lead plate and the mounting shaft will not become defective.

(e) Embodiment 1 is a dynamo, 2 is a lifting device for this dynamo 1, and 3 is a metal headlight mounting stay. The end is fixed to the lifting device 2 with a screw 4, and a headlamp mounting shaft 5 is provided protruding from the free end.

Reference numeral 6 denotes a headlamp case consisting of a translucent front cover 7 and a synthetic resin rear case 8. At the rear of the rear case 8, a recessed portion 10 having a concave spherical surface 9 for sliding is formed. Then, the mounting shaft 5 is inserted into the headlamp case 6 through the free through hole 11 of the concave spherical surface 9, and is tightened and fixed with a nut 13 via the curved washer 12, thereby fixing the headlamp case 6 to the free through hole 11 of the concave spherical surface 9. The mounting shaft 5 can be slid vertically and horizontally within the movement range of the mounting shaft 5 in the through hole 11. Furthermore, 14 is a reflector housed in the headlamp case 6, 15 is a light bulb attached to this reflector 14 via a conductive light bulb socket 16, and 1
A first lead plate 7 has its free end in contact with the tail terminal of the light bulb 15, and the first lead plate 17 is electrically connected to the output terminal of the dynamo 1 via a lead wire 18.

Reference numeral 19 connects the peripheral terminal of the light bulb 15 to the socket 1.
A second lead plate for grounding to the headlamp mounting shaft 5 via the conductive metal strip 6, which has a spherical contact surface 20 recessed in the base end of the conductive metal strip plate, and has a mounting surface 21 and a free end acting portion 22. By inserting the mounting surface 21 into the insertion rib 23 on the inner surface of the rear case 8, the free end acting portion 22 of the second lead plate 19 is formed. The light bulb socket 16
and is fixed to the rear case 8 with the spherical contact surface 20 pressed against the tip of the headlamp mounting shaft 5.

That is, the tip of the mounting shaft 5 is connected to the second lead plate 19.
Since it is in pressure contact with the spherical contact surface 20 of the headlight case 6, even if the headlight case 6 is slid up, down, left or right, the tip will come into pressure contact with any position of the spherical contact surface 20, ensuring a good electrical connection. It is something that is done.

(f) Effect of the invention The block dynamo of the invention is constructed as described above, and in particular, the second lead plate is fixed to the headlamp case, and the second lead plate is attached to the tip of the headlamp mounting shaft in its spherical shape. Since the electrical connection is made by pressing the contact surfaces, the attachment state of the second lead plate will not loosen no matter how much the headlight case is slid in the vertical and horizontal directions relative to the dynamo. 2. There is no possibility of electrical failure between the lead plate and the headlight mounting shaft.
The purpose is to obtain something that can be used stably over a long period of time.
