Detailed Description
Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
First, an electric wire in which the position of a terminal is corrected by an electric wire correction device according to an embodiment of the present invention will be described. Fig. 1 is a perspective view of an electric wire having a plurality of core wires each attached with a terminal.
As shown in fig. 1, the electric wire 11 has four core wires 13, and is used for, for example, an in-vehicle ethernet (registered trademark). These core wires 13 are each composed of a conductor 15 and a sheath 17. The conductor 15 is formed by, for example, twisting a wire made of a conductive metal material such as copper, a copper alloy, aluminum, or an aluminum alloy. The sheath 17 is made of an insulating resin material and covers the outer periphery of the conductor 15. These core wires 13 are bundled and covered with a sheath 19 made of an insulating resin material to form one electric wire 11.
At the end of the electric wire 11, the core wire 13 is exposed from the sheath 19. The conductors 15 are exposed at the ends of these core wires 13, and the terminals 21 are attached to the ends of the core wires 13 where the conductors 15 are exposed. The terminals 21 attached to the plurality of core wires 13 of the electric wires 11 are inserted and accommodated in the terminal accommodating chamber of the housing (not shown).
The terminal 21 is formed of a conductive metal material such as copper or a copper alloy. In this example, the terminal 21 is a female terminal and is conductively connected to a male terminal. The terminal 21 has an electrical connection portion 23 and a wire connection portion 25. The electrical connection portion 23 is formed in a square tube shape, and is electrically connected to the male terminal by inserting a pin-shaped protruding piece portion of the male terminal into the electrical connection portion 23. The terminals 21 are press-fixed by press-contacting the wire connection portions 25 to the respective core wires 13 with the conductors 15 exposed.
Next, an electric wire correction device for correcting the posture of the terminal 21 of the electric wire 11 will be described.
Fig. 2 is a perspective view of an electric wire correction apparatus according to an embodiment of the present invention. Fig. 3(a) and 3(B) are views showing rotation of a correction portion constituting the electric wire correction device, and are front views of the electric wire correction device. Fig. 4 is a perspective view showing a configuration of a correction portion constituting the electric wire correction device.
As shown in fig. 2, the electric wire correction device 100 includes a gripping mechanism 30 and a correction mechanism 40.
The clamping mechanism 30 has an electric wire housing portion 31 and a clamping portion 32. The wire housing 31 is formed in a groove shape capable of housing the wire 11. The electric wire 11 is fitted into the electric wire housing 31 from above so as to be housed in the electric wire housing 31. The gripping portion 32 has gripping claw portions 33, the gripping claw portions 33 are provided so as to be movable in directions to approach and separate from each other, and the end portion of the electric wire 11 accommodated in the electric wire accommodating portion 31 is interposed between the gripping claw portions 33. The gripping portion 32 grips the end of the electric wire 11 with the gripping claw portion 33 by moving the gripping claw portion 33 in the direction to approach each other. Further, the gripping portions 32 release the gripping of the electric wire 11 by moving the gripping claw portions 33 in the directions to separate from each other. In the gripping portion 32, the gripped electric wire 11 reciprocates along the axial direction thereof.
The correction mechanism 40 has a support portion 41 and a correction portion 42. The correction portion 42 is supported by the support portion 41. The correction portion 42 is rotatably supported about a horizontal axis with respect to the support portion 41. The rotation axis of the support 41 is coaxial with the axis of the electric wire 11 held by the holding portion 32 constituting the holding mechanism 30. That is, the correcting portion 42 is rotatable about the axis of the electric wire 11 clamped by the clamping portion 32.
As shown in fig. 3(a) and 3(B), the correcting portion 42 rotatably supported by the supporting portion 41 is rotated left and right within a range of about 90 degrees by a rotation driving unit (not shown). Specifically, the correcting portion 42 rotates about the axis of the electric wire 11 in one direction (the direction indicated by the arrow "a" in fig. 3 (a)) as shown in fig. 3(a) and in the other direction (the direction indicated by the arrow "B" in fig. 3 (B)) as shown in fig. 3 (B).
As shown in fig. 4, the correcting portion 42 has a spacer 50 and a guide member 60. The partition 50 has a horizontal partition 51 extending in the horizontal direction and a vertical partition 52 extending in the vertical direction, and the vertical partition 52 is arranged orthogonal to the horizontal partition 51 to form a cross shape. The horizontal partition 51 and the vertical partition 52 have tapered portions 51a, 52a, respectively, the tapered portions 51a, 52a being formed in a tapered shape whose thickness gradually decreases toward the tip thereof.
The guide member 60 has a pair of horizontal guide members 61 and a pair of vertical guide members 62. The pair of horizontal guide members 61 are slidable in directions to approach and separate from each other. Further, the pair of vertical guide members 62 can slide in the direction of approaching and separating from each other. In the vertical guide member 62, escape recesses 63 having openings facing each other are formed. The horizontal partition 51 and the vertical partition 52 constituting the partition 50 can be accommodated in the escape recess 63 of the vertical guide member 62. Further, the horizontal guide member 61 is insertable into and removable from the escape recess 63 of the vertical guide member 62.
The portion of the correction portion 42 surrounded by the horizontal guide member 61 and the vertical guide member 62 is divided into four terminal accommodation portions 71 by the horizontal partition 51 and the vertical partition 52 of the partition 50. The correcting mechanism 40 is provided such that the terminals 21 attached to the respective core wires 13 of the electric wires 11 are inserted into the respective terminal accommodating portions 71 by clamping and moving the electric wires 11 to the correcting mechanism 40 by the clamping portions 32 of the clamping mechanism 30. The correction portion 42 has an abutting plate 73 on the deep side of the terminal accommodating portion 71. The tip of the terminal 21 inserted into the terminal accommodating portion 71 abuts against the abutting plate 73. The terminal 21 is positioned in the axial direction by abutting the tip end of the terminal 21 against the abutting plate 73.
Next, a method of correcting the electric wire 11 using the electric wire correction apparatus 100 will be described.
Fig. 5(a) to 5(D) are views showing a correction process of correcting the posture of the terminal attached to the core wire by using the electric wire correction device, and fig. 5(a) to 5(D) each show a schematic side view and a schematic front view of the end portion of the electric wire.
As shown in fig. 5(a), in the electric wire 11 having a plurality of core wires 13 having ends respectively attached with the terminals 21, for example, the core wires 13 may extend to be separated from the axis of the electric wire 11, and the postures of the terminals 21 may be inclined and different.
In this way, the electric wires 11 different in the posture of the terminal 21 are accommodated in the wire accommodating part 31 of the gripping mechanism 30 of the electric wire correction device 100. Then, in the gripping mechanism 30, the gripping portions 32 are driven to move the gripping claw portions 33 in the direction approaching each other, and the vicinity of the end portion of the electric wire 11 is sandwiched and gripped by the gripping claw portions 33.
The gripping mechanism 30 moves toward the correcting mechanism 40. Thus, as shown in fig. 5(B), the terminals 21 attached to the respective core wires 13 of the electric wires 11 are inserted into the terminal accommodating portions 71 of the correction portions 42. Therefore, the terminals 21 attached to the core wires 13 of the electric wires 11 are distributed vertically and horizontally by the horizontal and vertical partitions 51 and 52 of the partition 50 of the correction portion 42. At this time, the terminal 21 is positioned in the axial direction by abutting the tip end of the terminal 21 against the abutting plate 73.
As shown in fig. 5(C), the pair of horizontal guide members 61 of the correcting portion 42 moves in the direction approaching each other, and the pair of vertical guide members 62 moves in the direction approaching each other. Therefore, the terminal 21 is pressed against the vertical partition 52 by the horizontal guide member 61, and both side surfaces of the terminal 21 are sandwiched between the vertical partition 52 and the horizontal guide member 61. Further, the terminal 21 is pressed against the horizontal partition 51 by the vertical guide member 62, and the upper surface and the lower surface of the terminal 21 are sandwiched between the horizontal partition 51 and the vertical guide member 62. Therefore, the terminal 21 is held in a state of being aligned in a posture along the axis of the electric wire 11.
Next, the correction portion 42 is rotated relative to the support portion 41 in one direction (a direction in fig. 5 (C)) and the other direction (B direction in fig. 5 (C)). Therefore, the terminal 21 held by the correcting portion 42 is rotated about the axis of the electric wire 11, and the core wire 13 drawn out from the electric wire 11 is twisted and straightened. The rotation of the correction portion 42 is preferably repeated a plurality of times.
Thereafter, the pair of horizontal guide members 61 of the correcting portion 42 moves in the direction separating from each other, the pair of vertical guide members 62 moves in the direction separating from each other, and further, the chucking mechanism 30 moves in the direction separating from the correcting mechanism 40. Therefore, the respective terminals 21 of the electric wire 11 whose posture is corrected are pulled out from the terminal accommodating portions 71 of the correcting portions 42. Further, the gripping claw portions 33 of the gripping portion 32 are moved in the direction of separating from each other, and the electric wire 11 can be taken out from the gripping mechanism 30.
In the electric wire 11, as shown in fig. 5(D), the terminals 21 attached to the core wires 13 are aligned in a posture along the axis of the electric wire 11. Therefore, according to the electric wire 11, the plurality of terminals 21 can be simultaneously inserted into the terminal accommodating chambers of the housing and easily attached.
As described above, according to the electric wire correction method and the electric wire correction device 100 of the present embodiment, the spacer 50 is provided between the terminals 21 to which the core wires 13 led out from the end of the sheath 19 are attached, and the spacer 50 is alternately rotated in one direction and the other direction about the axis of the electric wire 11 with respect to the electric wire 11. Therefore, the core wire 13 drawn out from the electric wire 11 can be twisted and straightened, and the posture of the terminal 21 attached to the core wire 13 can be corrected and easily aligned at the same time.
Therefore, the operation of inserting the terminals 21 into the terminal accommodating chambers of the housing can be smoothly performed, and for example, the operation of attaching the terminals 21 to the housing can be easily automated.
For example, in the case where the electric wire 11 has four core wires 13, a cross-shaped spacer 50 having a horizontal spacer 51 and a vertical spacer 52 is provided between the terminals 21 attached to the four core wires 13, and the cross-shaped spacer 50 is alternately rotated in one direction and the other direction about the axis of the electric wire 11 with respect to the electric wire 11. Therefore, the postures of the terminals 21 attached to the four core wires 13 can be corrected at the same time and easily aligned.
Further, in a state where the terminals 21 are pressed against and held on the spacer 50 by the guide members 60, the spacer 50 is alternately rotated in one direction and the other direction with respect to the electric wire 11 about the axis of the electric wire 11 together with the guide members 60, so that the postures of the terminals 21 can be corrected to be aligned in the same direction.
In the above embodiment, the case where the terminals 21 of the electric wire 11 having the four core wires 13 to which the terminals 21 are attached respectively are aligned has been exemplified, but the number of the core wires 13 is not limited to four, and may be, for example, two or three. In the case where the electric wire 11 has two core wires 13, the horizontal partition 51 and the vertical guide member 62 may be removed, and the respective terminals 21 may be aligned and sandwiched between the vertical partition 52 and the horizontal guide member 61. Even when the number of the core wires 13 is two, the cross-shaped spacer 50 can be used as in the case of four core wires.
In the electric wire correction device 100, when the terminals 21 attached to the respective core wires 13 are male terminals having tabs, the abutment plate 73 of the correction portion 42 is modified to be an abutment plate for the male terminals having escape portions into which the tabs of the terminals 21 are inserted.
