Abstract
The utility model discloses a bus bar for flat wire motor stator wiring, which comprises plastic and a copper terminal integrated on the plastic, wherein a protruding opening is arranged at the extending position of the copper terminal on the plastic, the protruding opening comprises a large rectangular area and a small rectangular area, the extending position of the copper terminal is positioned in the large rectangular area and is opposite to the small rectangular area, the large rectangular area is a process hole matched with an injection mold, the small rectangular area is used for penetrating and fastening a hairpin wire, one side surface is attached to the copper terminal when the hairpin wire penetrates into the small rectangular area, the other three side surfaces are contacted with the plastic, and the top end is aligned with and welded with the top end of the copper terminal. The wiring busbar is limited as a whole by the four vertical side surfaces of the vertical and vertical direction perpendicular to the vertical direction of the hairpin line, so that the hairpin line is tightly fixed with the stator winding, the influence of vibration on welding spots of the wiring busbar is effectively reduced, and the risk of failure of welding spots is reduced.
Description
Technical Field
The utility model belongs to the field of new energy motors, and particularly relates to a bus bar for flat wire motor stator wiring.
Background
More and more applications of flat wire motor are in new forms of energy motor market, for the convenience of the wiring of flat wire motor winding, prevent the short circuit risk, convenient automated production, flat wire motor stator adopts the female design of arranging of wiring in the one end of winding, the female arranging of wiring adopts rubber coating injection molding process to wrap up several copper terminals (including the wire jumper, neutral conductor and U, V, W three-phase copper bar) inside the plastic, the female arranging of wiring is in the same place through its integrated copper terminal and hairpin line welding, thereby be fixed to motor winding. However, due to the vibration condition, the welding point of the wiring busbar is always at risk of cracking, thereby causing the failure of the motor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a bus bar for flat wire motor stator wiring, which is used as a whole to limit the vertical and vertical four side surfaces of a hairpin wire, so that the hairpin wire and a stator winding are tightly fixed together, the influence of vibration on a welding point of the hairpin wire is effectively reduced, and the risk of failure of the welding point is reduced.
The technical scheme adopted by the utility model is as follows:
the utility model provides a flat line motor stator wiring is with female arranging, including plastic and the copper terminal of integration on the plastic, the extended position of copper terminal is equipped with "protruding" shape opening on the plastic, protruding "shape opening is regional and little rectangle region including big rectangle, the extended position of copper terminal is located big rectangle region and just to little rectangle region, big rectangle region is the fabrication hole that suits with injection mold, little rectangle region is used for penetrating and fastening hairpin line, a side pastes on the copper terminal when hairpin line penetrates little rectangle region, all the other three sides and plastic contact, the top aligns and welds with copper terminal top.
Further, the orientation of the "convex" shaped opening is consistent with the trend of the copper terminal corresponding to the opening.
Furthermore, the plastic is provided with a positioning hole for the copper terminal.
The utility model has the beneficial effects that:
the wiring busbar is limited as a whole by the four vertical side surfaces of the vertical and vertical direction perpendicular to the vertical direction of the hairpin line, so that the hairpin line is tightly fixed with the stator winding, the influence of vibration on welding spots of the wiring busbar is effectively reduced, and the risk of failure of welding spots is reduced.
