Problems solved by technology

However, in these aluminum conductor terminal devices, since the aluminum conductor and the terminal member are connected to each other by using a resistance welding machine or an ultrasonic welding machine, the melting amount of the aluminum conductor is relatively small, and therefore, the difference between the materials of the aluminum conductor and the terminal member Insufficient fusion between

Example

[0032] The first embodiment

[0033] figure 1 It is a perspective view of the aluminum conductor terminal device 1 according to the first embodiment of the present invention.

[0034] The terminal device 1 is a contact connection type terminal and is used for connection of power lines of electrical equipment such as rotating electric machines. For example, the terminal device 1 can be used to provide electrical connections in the stator coils of a vehicle-mounted rotating electric machine. In this case, the terminal device 1 is used to connect a plurality of phase windings of the stator coil. The terminal device 1 is used to weld a plurality of phase windings to each other.

[0035] In addition, the terminal device 1 can be used to connect multiple phase windings to a circuit. To this end, the terminal device 1 includes an electrode part, and the circuit is contact-connected with the electrode part to provide electrical connection between the phase winding and the circuit. In thi...

[0067] Next, the second embodiment of the present invention will be explained. In the following embodiments, the same parts as those shown in the previous figures are given the same reference numerals and will not be described again unless it is necessary to understand the embodiments. Picture 8 It is a perspective view of the aluminum conductor terminal device of the second embodiment. Such as Picture 8 As shown, the aluminum conductor terminal device 1 of the second embodiment includes a terminal member 23 having an electrode portion 23d. The electrode portion 23d is bent 90 degrees with respect to the axial direction of the tubular portion 3a. The electrode portion 23d extends in a direction opposite to the direction in which the aluminum conductor 2 extends. The flat portion of the electrode portion 23d expands perpendicular to the axis of the tubular portion 3a.

Abstract

Provided are aluminium conductor terminal device and a manufacturing method thereof. The aluminium conductor terminal device includes an aluminium conductor made of a first metal material composed of aluminium or alumininum alloy, a terminal component made of a second metal material different from the first metal material, and a metal welding member formed by generating a melted metal by melting a part of the front end of the aluminium conductor and a part of the terminal component, and cooling the melted metal to concrete the melted metal. The terminal component is shaped to enclose the front end of the aluminium conductor and have side walls so as to define an accepting pool for accumulating the melted metal on the inner side.

Description

technical field [0001] The present invention relates to an aluminum conductor terminal device comprising an aluminum conductor made of aluminum or an aluminum alloy and a terminal device made of a metal other than the aluminum conductor and combined with the aluminum conductor. Background technique [0002] Such an aluminum conductor terminal device is described, for example, in Japanese Patent Application Laid-Open No. 2005-108445 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2005-108608 (Patent Document 2). These documents describe the construction of aluminum conductors in combination with copper crimp terminals. The conventional aluminum conductor terminal device described above is advantageously used for, for example, power line connection in a vehicle alternator or an automobile rotary electric machine as described in Japanese Patent Laid-Open No. 2007-181396 (Patent Document 3). [0003] Since dissimilar metal joints such as aluminum and copper jo...
