Description

[Detailed Description of the Invention] The present invention relates to a generator in which the structure of the connection terminal of the generator coil of a magnet generator or the like is improved.

Conventionally, this kind of device has an L-shaped connection terminal formed by punching out a brass or copper plate, one end of this L-shaped connection terminal is connected to an external lead wire, and the other end is connected to the terminal of the generating coil. was wrapped around it.

However, with the above-mentioned conventional method, since the connection terminals are manufactured by punching out a plate, burrs are generated due to the punching, and if a thin wire with a diameter of 0.2 mm or less is wound, the burrs will damage the fine wire, causing vibrations in the internal combustion engine and generating coils. There is a drawback that the wires may break due to applying force to the connection terminals during post-processing, especially when connecting external lead wires.

In addition, the external part of the connecting terminal that protrudes from the power generation coil is long because it connects to the external lead wire, and it is bent during the process or bent into a circle to connect to the external lead wire, so the connecting terminal There is a disadvantage that the connecting terminal itself is weakened by being bent too many times, or it may break and damage the generating coil.

In order to solve the above-mentioned drawbacks, the present invention uses a round bar wire instead of a plate for the terminal structure, thereby eliminating the burr at the connection part with the thin generating coil, and making the connection part with the external lead wire U-shaped. By shaping the lead wire into the U-shaped hole, the lead wire can be soldered as it is, so there is no need to bend the external terminal, and one end of the U shape can be bent to stabilize the terminal. The purpose of this invention is to provide a power generator that can ensure the same level of terminal stability as when using a plate.

The present invention will be described below with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, 1 is a laminated core, 2 is an insulating paper, 3 is a side insulator, 4 is a power generating coil, 5 is a connection terminal made of a round bar wire, and 5a is a U-shaped exterior of the connection terminal 5. A connecting part, 5b is a winding part for wrapping the end of the power generating coil 4 around the connecting terminal 5, 5C is a removal prevention part, 5d is an extension part for stabilizing the connecting terminal 5, 6 is an exterior tape, 7 is an insulating tape, 8 is a terminal fixing tape.

In the above configuration, after winding the insulating paper 2 several times on the laminated core 1, the side insulators 3 were fitted to both ends of the core 1, and the winding start and other end portions were grounded to the laminated core 1 on the core insulating paper 2. A power generating coil 4 is wound around the power generating coil 4, and an insulating tape 7 is wound on top of the power generating coil 4.

Then, the connection terminal 5 is wound by wrapping the other end of the winding coil 4 around the part 5b, and then fixing the connection terminal 5 on the insulating tape 7 with the terminal fixing tape 8. Exterior tape 6 is applied on insulating tape 7 with only external connection portion 5a protruding to the outside.

Then, a lead wire (not shown) is inserted into the U-shaped hole of the external connection portion 5acr) of the connection terminal 5, and the lead wire and the external connection portion 5a are soldered.

Here, the connection terminal 5 is formed by bending a single round bar wire, and the external connection part 5a is formed by bending it into a U-shape at a sufficient interval to allow the lead wire to pass through. Both end surfaces of this external connection part 5a are bent in the same direction into an L-shape, and one of them is wound to form a part 5b, and the tip of the part 5b is further bent into an L-shape and removed. A prevention portion 5C is formed to prevent the winding end portion of the generator coil 4 wound around the winding portion 5b from slipping off from the winding portion 5b during the winding operation.

The other L-shaped bent part forms an extension part 5d for stably fixing the connection terminal 5 to the insulating tape 7, and the end part of the generating coil 4 is not wound. The extension part 5d is a comb having a length shorter than that of the part 5b so that it can be easily wrapped around the part 5b.

The winding portion 5b and the extension portion 5d are arranged and fixed in the axial direction on the outer surface of the power generating coil 4 while maintaining a predetermined interval.
The external connection portion 5 a is projected toward the outer circumference of the power generation coil 4 .

In the above-mentioned embodiment, the end of the winding of the power generating coil 4 is wound around the connecting terminal 5, but the end of the winding of the power generating coil 4 is connected to the connecting terminal 5.
may be wound around the portion 5b.

As mentioned above, in the present invention, since the connecting terminals are made of round bar wire, even when a thin generating coil is wound, the generating coil will not be damaged at the corners or corners, and the connecting terminals can be placed at specified intervals. Since it is fixed with two legs arranged axially on the outer surface of the generating coil, it not only has the same stability as using a plate, but also has the same stability for generating coils of different diameters. 2 connection terminals can be used, greatly improving versatility.Furthermore, if the external connection part protruding from the generator coil is made into a U-shape and made low in height, external forces can be reduced. In addition, because of the U-shape, even if the generator coil is insulated with varnish or epoxy resin, there will be no holes and connection with external lead wires is easy. There is no need to bend the terminal when connecting the lead wire, making it mechanically strong.
Furthermore, the length of the extension part extending in the same direction is made shorter than the length of the wrapping part, and the tip of the wrapping part is bent to form a pull-out prevention part, so that the wrapping part can be unimpeded by the extension part. The coil terminal can be wound around the coil terminal, and the winding can surely prevent the coil terminal from being pulled out later, and has the excellent effect of being easy to assemble.
