The present invention realizes the arrangement of multiple wiring terminals on one rectifier bridge 7 by changing the structure of the rectifier bridge 7, thereby facilitating subsequent wiring operations; at the same time, the first positioning terminal 71 and the second positioning terminal 73 in the present invention can integrate multiple wiring terminals into one component, thereby simplifying the overall structure of the rectifier bridge 7; at the same time, in the present invention, the third support plate 716 and the fourth support plate 732 are arranged relatively to each other, and the excitation diode is placed between the two, and the connecting groove 733 and the welding groove 717 are used for placing the excitation diode lead;In summary, the present invention changes the connection mode of the leads of various components on the traditional rectifier bridge bracket 72. By setting the first positioning terminal 71 and the second positioning terminal 73, a welding place is provided for the leads of various components on the rectifier bridge 7. At the same time, by setting the first positioning terminal 71 and the second positioning terminal 73, the leads of various components are integrated on the rectifier bridge 7 terminals during welding, so that each lead or connecting wire is welded and fixed on the rectifier bridge bracket 72, thereby achieving the fixation of the welding position of the entire rectifier bridge bracket 72, avoiding the problem of the messy welding position of the leads on the traditional rectifier bridge bracket 72. That is, by using the first rectifier terminal and the second rectifier terminal, the entire device structure of the rectifier bridge 7 becomes simpler, reducing the difficulty of welding the rectifier bridge bracket 72 with the leads of various components, and also making the manufacturing process of the rectifier bridge bracket 72 relatively simple. ;

[0033] Preferably, the first positioning terminal 71 in the present invention also includes an extension plate 718 connected to the first terminal body 711, and the end of the extension plate 718 away from the first terminal body 711 is provided with a transverse connecting plate 719 for setting the first connecting hole 7190; the first connecting hole 7190 is connected to the first connecting stud 10; the extension plate 718 in the present invention is provided to connect the first connecting stud 10, and the setting of the first connecting stud 10 provides another connection method between the rectifier bridge bracket 72 and the external lead or connecting wire, so that the rectifier bridge 7 can be connected to the lead or connecting wire at different positions as needed, making the internal layout of the generator more reasonable. , and at the same time, it can also achieve the desired function of the generator; as an optimization, the top view of the extension plate 718 in the present invention is approximately an L-shaped structure, that is, the extension plate 718 is a bent structure. This arrangement enables the extension plate 718 to have a good avoidance function, while achieving the connection of the first connecting stud, it also prevents it from interfering with other components of the generator; similarly, the second positioning terminal body 731 in the present invention is provided with a second connecting hole 734, and the first connecting stud 10 for connecting the lead is connected in the second connecting hole 734. This arrangement does not affect the normal use of the rectifier bridge 7, and also increases the number of connecting terminals for connection on the overall bridge.

[0034] Preferably, the first connecting stud 10 in the present invention includes a first supporting column 101, a connecting portion for connecting a wiring harness is provided at one end of the first supporting column 101, a fastening portion for fixing the first connecting stud 10 is provided at the other end of the first supporting column 101, the connecting portion includes a threaded rod 102 connected to the first supporting column 101 at one end; the other end of the threaded rod 102 is freely suspended; the fastening portion includes a first connecting column 103, and the first connecting column 103 is provided with straight stripes; the first connecting column 103 is connected to the first supporting column 101 through a second connecting column 104, the cross-section of the second connecting column 104 is a polygonal structure, and the horizontal cross-sectional area of ​​the second connecting column 104 is larger than the horizontal cross-sectional area of ​​the first connecting column 103 The first connecting column 103 of the present invention is provided with straight stripes, so that the first connecting column 103 is more tightly connected to the connecting part thereof, because the first connecting column 103 of the present invention is generally connected to a through hole; for example, it is connected to the first connecting hole 7190 on the first positioning terminal 71, and the two are interference fit. The first connecting column 103 is provided with straight stripes, which can increase the fastening force between the two to a certain extent, and prevent the first connecting stud 10 from falling off from the first terminal body 711. Preferably, the first connecting column 103 of the present invention is connected to the first supporting column 101 through the second connecting column 104, and the cross section of the second connecting column 104 is a polygonal structure, and the horizontal cross section area of ​​the second connecting column 104 is large. The horizontal cross-sectional area size of the first connecting column 103; such a setting, in order to better realize the limitation of the first connecting stud 10, the first connecting column 103 realizes the initial connection of the first connecting stud 10 by interference fit with the through hole on the connected component, but the resistance to rotational force can only rely on the extrusion force between the first connecting column 103 and the connected through hole, which cannot play a good limiting role. In order to avoid the rotation of the first connecting bolt, the present invention changes the structure of the second connecting column 104, so that the second connecting column 104 is a polygonal structure, and a rectangular structure is commonly used for easy processing. The second connecting column 104 is a polygonal structure, and in order to facilitate the passage of the second connecting column 104 on the component that cooperates with the second connecting column 104, The corresponding parts will also be provided with a connecting groove matched with the second connecting column 104, and the connecting groove cooperates with the second connecting column 104. Because the polygon has edges and corners, the rotation of the first connecting stud 10 can be well limited, thereby making the position of the first connecting stud 10 more fixed; the first support column 101 is provided to play a supporting role, and at the same time, in order to limit the position, the cross-sectional area of ​​the first support column 101 is the largest section of the four parts of the first connecting stud 10; as shown in the accompanying drawings; and the threaded rod 102 is provided to facilitate the connection between the first connecting stud 10 and the external lead or connecting wire; at the same time, the regulator 9 in the present invention includes a regulator 9 body, and a plurality of first connecting studs 10 are also provided on the regulator 9 body;The arrangement of the first connecting stud 10 here also provides more connection positions for the connection between the regulator 9 and other components, thereby better achieving the purpose of the present application. ;

[0035] Preferably, the rear end cover assembly 5 in the present invention includes a rear end cover body, on which a second connecting stud 11 is provided, and the second connecting stud 11 includes a second support column 111, and a threaded connecting column 112 with an external thread is respectively provided at both ends of the second support column 111; the setting of the second connecting stud 11 is for the same purpose as that of the first connecting stud 10, and because of the different setting positions, there are slight differences in structure, but the purpose to be achieved in the present invention is the same, so that a wiring terminal is also added to the rear end cover body, and the corresponding lead or connecting wire can be connected as needed, thereby better improving the scope of application of the generator disclosed in the present invention.

[0036] In the present invention, only the structure of each component is described, because the improvement of the structure is the focus of the present invention. In the present invention, there will be a connection relationship between the various components. Because the circuit needs to be connected, there may be circuit connection problems between some components, and the circuit connection is set according to specific requirements. Because the present invention has more connecting terminals, the internal circuit connection of the generator is diverse, but the problem of circuit connectivity is a well-known problem. As long as the specific function of the generator and the spatial layout of the internal components are determined, the circuit connectivity can be achieved through copper bars or connecting wires. The invention point is not here and will not be repeated here.

[0037] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
