Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, in the present embodiment, the motor wiring board with a bonding pad includes an insulating frame 1, where the insulating frame 1 is an arc-shaped plate structure, the structure may be matched with a vacant position on an inner surface of a motor, the insulating frame 1 is provided with a plurality of insulating frame fixing holes 11, the insulating frame fixing holes 11 are distributed at a position near an edge of the insulating frame 1, the number of the insulating frame fixing holes is 6, and the insulating frame 1 directly penetrates through the insulating frame fixing holes 11 to be fixed inside the motor through bolts, screws, or rivets.

Further, be equipped with three group PCB circuit boards 2 on insulating skeleton 1, three group PCB circuit boards 2 irregular distribution are on insulating skeleton 1, every group PCB circuit board 2 all includes power supply lead-out wire pad 3 to and enameled wire pad 4, every all weld on the power supply lead-out wire pad 3 has power supply lead-out wire 5, every all weld on the enameled wire pad 4 has enameled wire 6. The power supply lead-out wire 5 is soldered on the power supply lead-out wire bonding pad 3, the enameled wire 6 is soldered on the enameled wire bonding pad 4, the mutual connection is realized, the traditional mode that the power supply lead-out wire 5 is directly connected with the enameled wire 6 is changed, meanwhile, the mode that the other power supply lead-out wire 5 is connected with the enameled wire 6 through a wiring port is also changed, the connection stability and the connection reliability are improved, and the problems that the connection in the traditional connection mode is easy to fall off and the enameled wire is easy to break are solved.

Specifically, be equipped with a plurality of circuit card on the insulating skeleton 1 and establish ring 7, every power supply lead-out wire 5 all passes circuit card and establishes ring 7 and weld on power supply lead-out wire pad 3. In the use, because power supply lead-out wire 5 will link to each other with external equipment, can be wrench movement often to power supply lead-out wire 5 can have the incomplete condition of welding occasionally with the place that power supply lead-out wire pad 3 links to each other, at this moment receives the effect of wrench movement, and the easy fracture of welding department, and then influences stable connection each other, so this scheme has added on power supply lead-out wire 5 near the junction, has crossed stable in advance circuit card and has set up ring 7, through crossing circuit card and set up ring 7 and carry out the card to power supply lead-out wire 5 and hold, guarantee that the welding department does not receive external force interference.
