Conductor Wire Connecting Method, and Connecting Terminal, Stator, and Rotary Electric Machine
First Claim
1. An electric conductor wire connecting method comprising the steps of:
- inserting a plurality of enamel-coated conductor wires into a tube-shaped crimping connector, a connection component;
heating and crimping the enamel-coated conductor wires by pinching, and pressing, with electrodes and electrifying the crimping connector;
pressing and deforming the crimping connector and the enamel-coated wires simultaneously; and
discharging melted enamel coating from the crimping connector, wherein the method includes;
a fusing process wherein the conductor wires are electrically connected altogether in the crimping connector; and
a temporary crimping process wherein prior to the fusing process, a plurality of the enamel-coated conductor wires are inserted in the crimping connector and by mechanical pressurizing means temporary crimping is applied to the crimping connector, andwherein with respect to the cross-section of the crimping connector orthogonal to the axis of the crimping connector, temporary crimping applied to the crimping connector is utilized to suppress possible expansion in area due to external force given to both the end parts or either one of them in the cross-section while trying also to keep the area of both the end parts or either of them of the cross section as small as possible

Abstract
After melted enamel coating is discharged, a fusion process of electrical wire-to-wire connection is carried out inside a crimping connector. In the conductor connection method based on the fusion process, a plurality of enamel-coated conductor wires are inserted in the crimping connector prior to the start of the fusion process. Further, a temporary crimping process that provides the crimping connector a temporary crimping by mechanical pressurizing means is also performed. Addition of force at both end parts or either end part of the cross-section orthogonal to the axis of the above crimping connector may cause expansion, which needs to be suppressed with external force. At the same time, the cross-sectional areas corresponding to both end parts or either end part should preferably be as small as possible. The temporary crimping is applied to the crimping connector for this purpose.
