Definitions

  • the present invention is related to an electric cable end processing method for processing an electric cable end to be connected to a connector terminal, and an electric cable end structure.
  • It is conventional a process for soldering of an aluminum electric cable which includes: preliminarily heating aluminum core wires by immersing aluminum core wires in a bath of heated and molten solder; immersing the heated aluminum core wires into a flux bath; subsequently immersing the aluminum core wires again into the solder bath to cause the solder penetrate and adhere to the aluminum core wires; and soldering the aluminum core wires (see, PTL 1).
  • Another conventional process includes applying ultrasonic waves to molten solder in order to eliminate an aluminum oxide layer (see, PTL 2).
  • a sheath 3 located at an end portion of an electric cable 2 must also be immersed in molten solder 4 ultrasonically vibrated by an ultrasonic vibrating plate 5.
  • the sheath 3 will be damaged by heat of the molten solder 4.
  • shrinking the heat shrinkable tube by heating the heat shrinkable tube so as to be close contact with the conductor and the sheath.
  • ultrasonic vibrations may be applied to the molten solder into which the conductor is immersed.
  • an electric cable end structure comprising:
  • a heat shrinkable tube through which the conductor is inserted, wherein an end portion of the conductor is exposed by removing the sheath, a part of the end portion of the conductor including an end of the conductor is coated with solder, and
  • the conductor can be coated with solder without damaging the sheath.
  • the uncoated portion equivalent to the remaining part of the conductor is covered by the heat shrinkable tube, whereby the entire exposed portion of the conductor made from aluminum or an aluminum alloy is coated with solder. Even when the electric cable is connected to a terminal made from copper or a copper alloy, a copper-aluminum contact that has severe galvanic corrosion is not occurred, but a copper-tin contact that has less galvanic corrosion is provided.
  • molten solder can be ultrasonically vibrated and thereby attached to the exposed portion of the conductor made from aluminum or an aluminum alloy. An oxide layer of the conductor can thereby be removed and well coated with solder. In the electric cable end structure, an exposed portion of the conductor made from aluminum or an aluminum alloy is coated with solder. Accordingly, even when the electric cable is connected to a terminal made from copper or a copper alloy, a copper-aluminum contact that has severe galvanic corrosion is not occurred but a copper-tin contact that has less galvanic corrosion is provided. According to the present invention, it is possible to provide an electric cable end processing method for effecting end process to coat an entire exposed portion of a conductor made from aluminum or an aluminum alloy with solder as well as an electric cable end structure subjected to end process under the method.

  • an ultrasonic soldering apparatus 41 is used in the present embodiment.
  • the ultrasonic soldering apparatus 41 has a solder bath 42 that stores molten solder 14a, and an ultrasonic vibrating plate 43 is disposed in the solder bath 42.
  • the ultrasonic vibrating plate 43 is ultrasonically vibrated by an ultrasonic transducer (omitted from the drawings). As a result of the ultrasonic vibrating plate 43 being ultrasonically vibrated, ultrasonic vibrations are propagated to the molten solder 14a in the solder bath 42.
  • a part of the exposed portion of the core wires 12 is immersed from above into the molten solder 14a stored in the solder bath 42. In this immersing process, the sheath 13 is prevented from contacting the molten solder 14a.
  • a dimension of the immersed part of the core wires 12 is set to a dimension that is slightly longer than the normal exposed dimension Ln.
  • the ultrasonic vibrating plate 43 is ultrasonically vibrated by the ultrasonic transducer. As a result of this, an oxide layer formed over a surface of each of the core wires 12 is removed by the ultrasonic vibrations. The molten solder 14a spreads to the immersed part of the exposed portion and to interior potions of the core wires 12, whereupon a coating of the solder 14 is favorably formed.
  • the ultrasonic vibrating plate 43 is ultrasonically vibrated while the electric cable 11 is pressed toward the solder bath 42 so that the core wires 12 are held in contact with the ultrasonic vibrating plate 43.

  • the tube 15, in this state, is heated and thereby shrunk. Thereupon, the tube 15 closely contacts the core wires 12 and the sheath 13. Therefore, as shown in Fig. 2, the uncoated portion 16 of the core wires 12 are covered by the tube 15.

  • Galvanic corrosion may occur in a contact between dissimilar metals contact.
  • the galvanic corrosion is corrosion that occurs when a conductive liquid exists in a contact between dissimilar metals. Influence of the galvanic corrosion becomes greater as a potential difference between dissimilar metals increases. Since a copper-tin contact is smaller than a copper-aluminum contact in terms of a potential difference, the galvanic corrosion can be lessened in accordance with the embodiment of the invention.
  • an area of electrical conduction between the connector terminal 0 and the electric cable 11 can be realized as a copper-tin contact that will induce less severe galvanic corrosion.
  • the core wires 12 can be coated with the solder 14 without inflicting damage to the sheath 3. Further, the uncoated portion 16 of the core wires 2 is covered by the tube 15, whereby the entire uncovered portion of the core wires 12 made from aluminum or an aluminum alloy is coated with the solder 14. Even when the electric cable 11 is connected to the connector terminal 10 made from copper or a copper alloy, a resultant contact does not turn into a copper-aluminum contact that will induce severe galvanic corrosion but instead into a copper-tin contact that will induce less severe galvanic corrosion. Moreover, waterproof of clearance between the core wires 12 and the sheath 13 can also be assured by means of the tube 15.
  • the electric cable 11 can be shipped in the form of a product in which the core wires 12 are coated with the solder 14 in advance and in which the uncoated portion 16 is covered with the tube 15.
