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
This makes it difficult for the joint between the aluminum conductor and the terminal member to have a sufficiently high mechanical strength
Furthermore, this makes it difficult for the junction to have a sufficiently low resistance
In addition, it is difficult for the above aluminum conductor terminal devices to maintain the strength and resistance of the joints at their initial values ​​over a long period of time.

no. 1 approach

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

[0034] The terminal device 1 is a contact connection type terminal used for connection of a power supply line of electric equipment such as a rotating electric machine. For example, the terminal arrangement 1 may be used to provide electrical connections in the stator coils of an on-vehicle rotating electrical machine. In this case, the terminal arrangement 1 is used to connect a plurality of phase windings of the stator coil. A plurality of phase windings are soldered and connected to each other by means of the terminal device 1 .

[0035] Furthermore, the terminal arrangement 1 can be used to connect multiple phase windings to an electrical circuit. To this end, the terminal arrangement 1 comprises pole parts to which the electric circuit is contact-connected to provide an electrical connection between the phase windings and the elec...

[0067] Next, a second embodiment of the present invention will be described. In the following embodiments, the same parts as those shown in the preceding figures are given the same reference numerals and will not be described again unless necessary for understanding the embodiments. Figure 8 is a perspective view of an aluminum conductor terminal device of a second embodiment. Such as Figure 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 at 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 perpendicularly to the axis of the tubular portion 3a.

[0069] Next, a third embodiment of the present invention will be described. Figure 9 is a perspective view of an aluminum conductor terminal device of a third embodiment. Such as Figure 9 As shown, the aluminum conductor terminal device 1 of the third embodiment includes a terminal member 33 having an electrode portion 33d. The electrode portion 33d is bent at 90 degrees with respect to the axial direction of the tubular portion 3a, and is twisted at 90 degrees. The electrode portion 33d extends in a direction opposite to the direction in which the aluminum conductor 2 extends. The flat portion of the electrode portion 33d expands perpendicularly 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...
