Background
The flat copper wire motor is a mainstream driving motor in the new energy automobile industry. In the flat copper wire motor, the quality of the structure of the high-voltage terminal used by the three-phase high-voltage outgoing line directly influences the terminal manufacturing manufacturability, the manufacturing cost and the later welding manufacturability, and also can generate great influence on the heating of the armature, thereby causing the armature loss to increase and even burning the armature in serious conditions.
In the prior art, a side flanging is adopted at the joint of a high-voltage terminal structure and a copper wire, and in order to meet the sheet metal process, a crack stopping groove needs to be arranged at the side flanging, so that a region with a sudden change of sectional area is formed in the terminal, the conductive sectional area in the whole circuit is influenced, and the terminal becomes a potential heating point in an armature.
In addition, when receiving the structure restriction, when adopting the unilateral to bend, when terminal and copper line welding, the copper line can't effective positioning, has increased the welded degree of difficulty, has reduced welding quality, causes the product to have the risk of poor reliability.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high-voltage terminal for flat copper wire motor, this kind of high-voltage terminal for flat copper wire motor solve among the prior art high-voltage terminal raw and other materials utilization ratio low, the electrically conductive sectional area is inhomogeneous, the side turn-ups bend more difficult and the unable effective technical problem who fixes a position of copper line.
The utility model provides a pair of a high-voltage terminal for flat copper wire motor, including a bar conductive metal plate, wherein, the one end of bar conductive metal plate be provided with a first portion of bending, first portion of bending in be provided with an opening, be provided with the clearance between the extension section of bar conductive metal plate and first portion of bending, the opening with clearance intercommunication.
Further, the first bending part is U-shaped.
Further, the strip-shaped conductive metal plate is parallel to the extension section of the first bending portion.
Furthermore, the other end of the strip-shaped conductive metal plate is provided with a second bending part, and the second bending part is bent at a right angle and is parallel to the extension section of the first bending part.
Compared with the prior art, the utility model, its effect is positive and obvious. Because the first bending part is bent in the length direction of the strip-shaped conductive metal plate, the material utilization rate is improved, the waste of raw materials is reduced, the manufacturing cost is reduced, in the processing and bending process, the distance that the first bending part can clamp when bending is longer, the bending is easier, the strip-shaped conductive metal plate is formed with two side faces at the opening, when a copper wire passes through the opening and is welded with the strip-shaped conductive metal plate, the two side faces can effectively position the copper wire, the welding difficulty is reduced, the welding quality is improved, the conductive area of the strip-shaped conductive metal plate is uniform, the heating risk is reduced, and the reliability of a product is improved.
