Method of connecting electric cable to connector terminal and compression-molding die

1. A method of connecting an electric cable to a connector terminal, the method comprising:

providing the connector terminal including a barrel portion and a tab terminal portion configured to be electrically connected to a mating terminal,

exposing a conductor at an end portion of the electric cable from an outer cover of the electric cable,

arranging the connector terminal in a lower die so that the end portion of the electric cable in which the conductor is exposed is arranged in the barrel portion of the connector terminal,

pressing a crimper with respect to the barrel portion of the connector terminal arranged in the lower die to crimp the barrel portion,

overlapping the lower die with an upper die such that the crimper enters a communication hole which is formed in the upper die and closes the communication hole to form an injection space around the crimped barrel portion and the end portion of the electric cable, the injection space being defined by the lower die, the upper die and the crimper closing the communication hole; and

injecting a resin in the injection space, thereby to form a resin mold that covers and waterproofs a connecting location between the barrel portion and the end portion of the electric cable,

wherein the lower die and the crimper are used during the crimping of the barrel portion and the injecting of the resin.

2. The method according to claim 1 , wherein the resin is injected in the injection space from a gate hole formed in the upper die or the lower die.

3. The method according to claim 1 , wherein the crimper is included in the upper die.

4. The method according to claim 1 , wherein when the crimper enters the communication hole the crimper fluidly closes the communication hole.

5. The method according to claim 1 , wherein the lower die is overlapped with the upper die after the crimper is pressed with respect to the barrel portion.
