[0035] like Figure 1-8 As shown, this embodiment provides a generator, including a housing 10 and a terminal box 20. A through opening 11 is provided on the wall of the housing 10. The opening 11 may be circular or rectangular. The opening 11 may be located at any position in the axial direction of the housing 10, and is usually located at a position away from the power output end in the axial direction of the housing 10. An end cover 13 is provided at one end of the housing 10, and a fan is provided at the other end. The end cover 13 is generally a hub-type structure, and an air intake cover 14 is provided outside the end cover 13.

[0036] The junction box 20 includes a box body 21, a box cover 22 and a wiring terminal, and the junction box 20 is fixed on the housing 10. The two ends of the box body 21 are open, and one end covers the above-mentioned opening 11 on the housing 10. The box body 21 is usually rectangular, and a box cover 22 is provided at the other end of the box body 21, and the box cover 22 is detachably connected to the box body 21. The wiring terminal is fixedly arranged in the box body 21, and includes an insulating seat body 31, a control line connector 32, a conductive member 33 and a fixing member 34, wherein a first through hole 311 communicating with the above-mentioned opening 11 is provided on the insulating seat body 31, and the control line connector 32 is fixedly arranged in the first through hole 311, and the control line connector 32 is used to connect with the control line of the control panel of the generator set. A plurality of conductive members 33 are arranged at intervals on the insulating seat body 31, and the conductive members 33 are fixedly connected to the insulating seat. The terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel are both connected to the conductive member 33 and fixed by the fixing member 34, so that the conductive member 33 maintains electrical connection with the terminal 50 of the output wire and the terminal 60 of the panel main line.

[0037] In addition, in addition to the output wires and control wires of the generator, the excitation wires 40 of the generator also pass through the above-mentioned openings 11 to facilitate the connection of the carbon brushes on the generator.

[0038] In this embodiment, the terminal 50 of the output wire of the generator is directly electrically connected to the terminal box 20 on the wall of the casing 10, and there is no need to extend a longer section for connection with the control panel, thereby avoiding the situation in which the output wire extending outside the motor is dragged on the ground during on-site installation and use, that is, avoiding the output wire from contacting the ground, thereby avoiding the situation in which the output wire is damaged.

[0039] In one embodiment, Figure 6 As shown, the insulating seat 31 is also provided with a second through hole 312 connected to the opening 11, and the second through hole 312 can allow the excitation wire 40 to pass through. By providing the second through hole 312, the excitation wire 40 is properly constrained, and the excitation wire 40 is conveniently routed in the junction box 20.

[0040] In one embodiment, Figure 5 and 7As shown, the conductive member 33 is a conductive stud, one end of which is fixedly connected to the insulating seat body 31, and the fixing member 34 is a nut threadedly connected to the conductive stud. When the terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel are connected to the conductive member 33, the terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel are compressed by tightening the nut, so that the terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel remain electrically connected. In this embodiment, the terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel are provided with holes through which the conductive stud can pass, so that the two terminals can be put on the conductive stud. The above arrangement facilitates the electrical connection of the terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel.

[0041] In one embodiment, Figure 6 As shown, the insulating base 31 is provided with a socket 313, and one end of the conductive stud is embedded in the socket 313.

[0042] In one embodiment, Figure 6 As shown, two partitions 314 are arranged in parallel on both sides of each jack 313, and a wiring slot 315 is formed between the two partitions 314. Two adjacent jacks 313 can share one partition 314. The extension length of the partition 314 along the axial direction of the conductive stud can be greater than the sum of the thicknesses of the terminal 50 of the output wire of the generator and the terminal 60 of the panel main line of the control panel, so that the blocking effect is better.

[0043] In one embodiment, Figure 6 As shown, the plug hole 313 is a regular polygon hole or a circular hole. When the plug hole 313 is a regular polygon, the cross section of the above-mentioned one end of the conductive stud is also a regular polygon adapted thereto. When the plug hole 313 is a circular hole, the cross section of the above-mentioned one end of the conductive stud is circular. In order to ensure that a certain torque can be applied when the conductive stud is nutted, an anti-slip thread is provided at the above-mentioned one end of the conductive stud.

[0044] In one embodiment, Figure 8 As shown, at least one positioning protrusion 321 is provided on the outer wall of the control line connector 32, and one positioning protrusion 321 may be provided on each of two opposite outer walls of the control line connector 32, and a positioning groove 316 matching with the positioning protrusion 321 is provided on the hole wall of the first through hole 311. The matching of the positioning protrusion 321 and the positioning groove 316 facilitates the installation of the control line connector 32 on the insulating seat body 31.

[0045] In one embodiment, Figure 6 As shown, first mounting seats 317 are provided at both ends of the insulating seat body 31, and the first mounting seats 317 extend to the outside of the box body 21. A third through hole 318 is provided on the first mounting seat 317. A mounting hole 12 corresponding to the third through hole 318 is provided on the wall of the housing 10. The mounting hole 12 is a threaded hole, and the terminal is connected to the housing 10 by a bolt that passes through the third through hole 318 and is threadedly connected to the mounting hole 12. Through the above arrangement, it is convenient to fix the junction box 20 on the wall of the housing 10.

[0046] In one embodiment, Figure 3 As shown, the second mounting seats 24 corresponding to the first mounting seats 317 are provided at both ends of the box body 21, and the fourth through holes 25 corresponding to the third through holes 318 are provided on the second mounting seats 24, and the bolts also pass through the fourth through holes 25. By providing the second mounting seats 24 corresponding to the first mounting seats 317, the strength of the connection portion between the junction box 20 and the housing 10 can be strengthened.

[0047] In one embodiment, Figure 3 , 5 As shown in FIG. 7 , the side walls of the box body 21 and the box cover 22 are provided with mounting grooves 23 adapted to the harness sleeve 70, and the mounting grooves 23 on the side walls of the box body 21 and the box cover 22 are both semicircular grooves. The excitation wire 40 and the panel main wire of the control panel are both installed in the harness sleeve 70 for protection, and the mounting grooves 23 on the box body 21 and the box cover 22 ensure that the harness sleeve 70 can pass through the side walls of the box body 21 and the box cover 22.
