Summary of Invention Technical Problem
As described above, in the connector terminal in which the
compressing-connection portion is molded, after a compression process in which an electric cable is compressed by crimping is performed, the electric cable is taken out from a crimping machine and arranged in a molding machine. In addition, in the molding machine, a molding process is performed in which a mold resin is injected and the resin mold is molded. Thus, it is necessary to provide separate pieces of equipment which perform a compression process and a molding process, respectively, and equipment costs increase. In addition, as described above, in a case where the compression process and the molding process are performed by separate facilities, improvement of productivity through automation is difficult.
The present invention is made in view of the situation described above. An object of the present invention is to provide a method of connecting an electric cable to a connector terminal and a
compression-molding die by which equipment costs are suppressed and automation is easily performed and thereby productivity can be improved.

In order to achieve the object described above, a connection method of an electric cable to a connector terminal according to aspects of the present invention may be configured by any of following configurations (1) to (3).
(1) A method of connecting an electric cable to a connector terminal including a barrel portion and a tab terminal portion to be electrically connected to a mating terminal, the method including: arranging the connector terminal in a lower die so that an end portion of the electric cable in which a conductor is exposed from an outer cover is arranged in the barrel portion of the connector terminal,
pressing a crimper with respect to the barrel portion to crimp the barrel portion,
overlapping the lower die with an upper die to form an injection space around the crimped barrel portion and the end portion of the electric cable; 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.
(2) The method according to the configuration (1), wherein the crimper enters a communication hole which is formed in the upper mold when the upper die overlaps the lower die.
(3) The method according to the configuration (1) or (2), wherein the resin is injected in the injection space from a gate hole formed in the upper die or the lower die.
In the method of connecting the electric cable to the connector terminal of the configurations (1) to (3) described above, compression of the electric cable and molding of the resin mold are performed in the same process so that complicated work of moving the connector terminal where the electric cable is compressed can be omitted and simplification of the work can be achieved. In addition, the equipment costs can be decreased and automation can be easily performed and thereby the improvement of productivity can be achieved compared to the case where compression of the electric cable and molding of the resin mold are performed separately in the compression machine and the molding machine, respectively.
In addition, in order to achieve the object described above, a compression-molding die according to aspects of the present invention may be configured by any of the following configurations (4) to (6).
(4) A compression-molding die, including:
a lower die having a terminal accommodating recess which accommodates a connector terminal that includes a barrel portion for arranging an end portion of the electric cable in which a conductor is exposed from an outer cover, and
an upper die that has a crimper which presses and crimps the barrel portion of the connector terminal accommodated in the terminal
accommodating recess, wherein

In addition, the equipment costs can be reduced and automation thereof can be easily performed and thereby an improvement in productivity can be achieved compared to a case where compression of the electric cable and molding of the resin mold are performed separately in a compression machine and a molding machine, respectively.

compression-molding die by which equipment costs are suppressed and automation is easily performed and thereby productivity can be improved.
Hereinabove, the present invention is described briefly. Details of the present invention will be clarified further by reading through the embodiments of the present invention described below with reference to the attached drawings.

Description of Embodiments
Hereinafter, an embodiment of the present invention is described with reference to the drawings.
Fig. 1 is a side view of a connector terminal, Fig. 2 is a side view of the connector terminal where a resin mold is provided, Fig. 3 is a perspective view of a compression-molding die according to the embodiment, and Figs. 4A to 4E are explanatory diagrams for explaining connecting processes of an electric cable to a connector terminal using a compression-molding die.
As shown in Figs. 1 and 2, a connector terminal 10 in which an electric cable 11 is connected by a connection method according to the embodiment, is formed of a conductive metal material such as copper or copper alloy with, for example, press processing. The connector terminal 10 includes a barrel portion 21 and a tab terminal portion 31.
The electric cable 11, in which the connector terminal 10 is connected, has, for example, a core wire (a conductor) 12 formed of aluminum or aluminum alloy, and an outer cover 13 which is extruded and coated around the core wire 12.
The barrel portion 21 has a core wire crimp part 22 and an outer cover crimp part 23. The core wire crimp part 22 compresses the core wire 12 exposed at an end portion of the electrical cable 11. Accordingly, the core wire 12 of the electric cable 11 and the connector terminal 10 are electrically connected. In addition, the outer cover crimp part 23 compresses the outer cover 13 in the end portion of the electric cable 11. Accordingly, a part of the outer cover 13 of the electric cable 11 is fixed to the connector terminal 10.
In addition, the connector terminal 10 is covered by a resin mold 15 around the periphery of the barrel portion 21 and the end portion of the electric cable 11. As described above, in the connector terminal 10, the connection position between the barrel portion 21 and the electric cable 11 is covered by the resin mold 15 and thereby the connection position of the electric cable 11 can be reliably waterproofed. As in this example, when the electric cable 11, which has the core wire 12 formed of aluminum or aluminum alloy, is connected to the connector terminal 10 formed of copper or copper alloy, there is a tendency for electrolytic corrosion such as bimetallic contact corrosion to arise in the connection position due to the connection position being permeated by water. However, the connection position is covered by the resin mold 15 so that high corrosion resistance can be obtained in the connection position.
Next, the compression-molding die which connects the electric cable 11 to the connector terminal 10 is described.
In the embodiment, as shown in Fig. 3, the electric cable 11 is connected to the connector terminal 10 using the compression-molding die 41. The compression-molding die 41 has a lower die 42 and an upper die 43 which overlaps the lower die 42.
In the lower die 42, a terminal accommodating recess 45 is formed. In addition, in one end side of the lower die 42, an electric cable accommodating groove 46, which communicates with the terminal accommodating recess 45, is formed. The terminal accommodating recess 45 of the lower die 42 can accommodate the connector terminal 10 in a state where the electric cable accommodating groove 46 side is considered to be a mold forming chamber 47 and the barrel portion 21 is arranged in the mold forming chamber 47.
The upper die 43 can move up and down with respect to the lower die 42. The upper die 43 has a gate hole 51 which communicates with the mold forming chamber 47 of the terminal accommodating recess 45 formed in the lower die 42.
In addition, in the upper die 43, a communication hole 52 having a rectangular shape seen in a plan view, which penetrates the front and back surfaces, is formed and a crimper 53 can be inserted into the communication hole 52. In other words, the upper die 43 includes the crimper 53. The crimper 53 has a crimper part 54 at a surface of the lower die 42 side. In addition, the upper die 43 has an electric cable holding groove 55 at a position opposite to the electric cable accommodating groove 46.
Thus, when the upper die 43 overlaps the lower die 42 in a state where the crimper 53 is inserted and accommodated in the communication hole 52, the upper side of the mold forming chamber 47 is covered and thereby an injection space is formed in the compression-molding die 41.
Next, an example is described, where the electric cable 11 is connected to the connector terminal 10 using the compression-molding die 41. (Arrangement Process)
First, as shown in Fig. 4A, the connector terminal 10 is
accommodated in the terminal accommodating recess 45 of the lower die 42 and an end portion of the electric cable 11, the core wire 12 of which is exposed, is arranged in the barrel portion 21 of the connector terminal 10.
(Compression-molding Process)
In this state, as shown in Fig. 4B, the crimper 53 moves down and the crimper 53 is pressed to the barrel portion 21 of the connector terminal 10 in the terminal accommodating recess 45. Then, the barrel portion 21 is crimped with respect to the electric cable 11 by the crimper part 54 of the crimper 53 and the electric cable 11 is connected to the barrel portion 21. Furthermore, as shown in Fig. 4C, the upper die 43 moves down. At this time, the crimper 53 enters the communication hole 52 formed in the upper die 43 without interfering with the upper die 43. Thus, as shown in Fig. 4D, the upper die 43 overlaps the lower die 42. Accordingly, the communication hole 52 of the upper die 43 is in a state of being closed by the crimper 53.
Thus, as described above, when the upper die 43 overlaps the lower die 42, the terminal accommodating recess 45 is closed and the injection space is formed by the mold forming chamber 47 and the crimper 53.
In addition, the electric cable 11 is held by the electric cable accommodating groove 46 of the lower die 42 and the electric cable holding groove 55 of the upper die 43 without a gap.
In this state, molten resin is injected from the gate hole 51 into the injection space and after predetermined time elapses, the resin is cured, so that as shown in Fig. 4E, the upper die 43 is moved up with the crimper 53. (Die Detaching Process)
After that, the electric cable 11 is connected and the connector terminal 10, where the connection position between the barrel portion 21 and the electric cable 11 is covered by the resin mold 15, is detached from the terminal accommodating recess 45 of the lower die 42.
As described above, according to the embodiment, compression of the electric cable 11 and forming of the resin mold 15 can be performed in the same process so that the complicated work of moving the connector terminal 10, where the electric cable 11 is compressed, can be omitted and thereby simplification of the work can be achieved. In addition, the equipment costs can be reduced and automation thereof can be easily performed and thereby an improvement in productivity can be achieved compared to a case where compression of the electric cable 11 and forming of the resin mold 15 are performed separately in a compression machine and a molding machine respectively.
In the embodiment described above, the gate hole 51 for injection of the resin is formed in the upper die 43 configuring the compression-molding die 41. Alternatively, as shown in Fig. 5, the gate hole 51 may be formed in the lower die 42 (at a side wall).
In addition, the present invention is not limited to the embodiments described above and can be appropriately altered, improved, or the like. In addition, material, shape, dimension, number, arrangement position, or the like of each of the configuration elements in the embodiment described above is arbitrary and is not limited if it can achieve the effects of the present invention. The present application is based upon and claims the benefit of Japanese patent application No. 2011-182992 filed on August 24, 2011, the contents of which are incorporated by reference in its entirety.
Industrial Applicability
The present invention is useful since the compression of the electric cable and molding of the resin mold can be performed easily in the same process, whereby equipment costs are suppressed and automation is easily performed and thereby productivity can be improved.
