Problems solved by technology
However, when using a rotating electrical machine, various vibrations are transmitted to the coil wire terminal and the phase loop wire terminal, and if the thermosetting resin does not penetrate the insulating material sufficiently, the coil wire terminal and the phase loop wire terminal will Vibration occurs in the insulator, and there is also a concern that the strength of the above-mentioned connection part will decrease
In addition, a certain amount of space is required to arrange the insulator, and if the insulator interferes with surrounding components, the coil wire terminal and the phase loop wire terminal are deformed, resulting in a decrease in the strength of the connection portion.

Embodiment Construction
[0026] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.
[0027] figure 1 It is a schematic structural diagram showing the stator 1 of the rotating electric machine of the present disclosure, figure 2 It is a top view showing the stator 1 . The stator 1 shown in these drawings together with a rotor not shown constitutes a three-phase AC motor as a rotating electric machine mounted as a driving source or a generator in, for example, an electric vehicle or a hybrid vehicle. The stator 1 of the present embodiment includes an annular stator core 2 , a plurality of stator coils 3u (U-phase coils), stator coils 3v (V-phase coils), and stator coils 3w (W-phase coils).
[0028] The stator core 2 is made, for example, of an electromagnetic steel sheet 21 formed into a substantially annular shape by press working (see figure 2 ) are formed by stacking multiple layers and connecting them in the stacking direction ...

The present invention relates to a stator of a rotating electric machine and a manufacturing method thereof. The stator of the rotating electric machine of the present disclosure includes a first conductive member and a second conductive member that are electrically connected to each other, and the end of the first conductive member is arranged adjacent to the end of the second conductive member and is welded from the end face side of the end, the wire winds around the non-welded parts of the ends of the first conductive member and the second conductive member. As a result, interference with surrounding components can be suppressed, and the durability of the connection portion of the first conductive member and the second conductive member can be further improved.
Description
technical field [0001] The present disclosure relates to a stator of a rotating electrical machine and a method of manufacturing the same. Background technique [0002] Conventionally, there is known a stator of a rotating electric machine, which includes a stator core, a stator coil wound around the stator core, a phase ring provided on the stator core, and a core at which coil wire terminal portions of the stator coil are connected. The connection part where the core wires of the phase ring wire terminal part of the wire and the phase ring are connected to each other by soldering or crimping the sleeve, and a cap shape with one side opening (with Bottom cylindrical) insulating member (for example, refer to Patent Document 1). In this stator, the coil wire end portion and the phase loop wire end portion are arranged parallel to each other, and are fitted into the insulator so that the connection portion is located on the bottom side (opposite side to the opening). Further...
