[0007] Problems to be solved by the invention

[0008] In order to reduce the weight of the cable, it is considered that the material of the braided shield is aluminum or aluminum alloy. In addition, in order to reduce costs and improve conductivity, it is considered that the material of the grounding member is copper, copper alloy, nickel or nickel alloy. In this case, galvanic corrosion may occur between the braided shield and the grounding member. In addition, the braided shield exposed at the end may come into contact with moisture and corrode.

[0009] In one aspect of the present disclosure, it is preferable to provide a method for manufacturing a terminal processing cable, a method for manufacturing a cable with a connector, and a terminal processing cable capable of suppressing corrosion of a braided shield.

[0010] Methods for solving problems

[0011] One aspect of the present disclosure is a method for manufacturing an end-processed cable, wherein the end-processed cable is manufactured by processing the end of the cable, the cable comprising a plurality of electric wires, a drain wire comprising copper or a copper alloy, a braided shielding member comprising aluminum or an aluminum alloy and disposed on the outer peripheral side of the plurality of electric wires and the drain wire, and a sheath disposed on the outer peripheral side of the braided shielding member; in the method for manufacturing the end-processed cable, the sheath is removed at the end, the braided shielding member located at the end is untied, the untied braided shielding member is overlapped from the outer peripheral side onto an adjacent portion of the cable adjacent to the end, and a range of the cable including the untied braided shielding member is covered with a heat shrink tube.

Therefore, it is not necessary to directly connect the braided shield containing aluminum or aluminum alloy to the grounding member containing copper, copper alloy, nickel or nickel alloy. As a result, it is possible to suppress the occurrence of galvanic corrosion between the braided shield and the grounding member. In addition, the heat shrink tube covers the range including the unwound braided shield, so that the braided shield can be prevented from contacting with moisture and corroding.

[0013] Another aspect of the present disclosure is a terminal-processed cable, which is an end-processed terminal cable, comprising a plurality of electric wires, a drain wire comprising copper or a copper alloy, a braided shielding member disposed on the outer peripheral side of the plurality of electric wires and the drain wire and comprising aluminum or an aluminum alloy, and a sheath disposed on the outer peripheral side of the braided shielding member, wherein at the end, the sheath is removed, the braided shielding member located at the end is untied, the untied braided shielding member is overlapped from the outer peripheral side toward an adjacent portion of the cable adjacent to the end, and a range of the cable including the untied braided shielding member is covered by a heat shrink tube.

[0014] The terminal processing cable can connect the drain wire including copper or copper alloy to the grounding member including copper, copper alloy, nickel or nickel alloy. Therefore, it is not necessary to directly connect the braided shield including aluminum or aluminum alloy to the grounding member including copper, copper alloy, nickel or nickel alloy. As a result, it is possible to suppress the galvanic corrosion between the braided shield and the grounding member. In addition, the heat shrink tube covers the range including the unwound braided shield, so it is possible to suppress the braided shield from contacting with moisture and corroding.

DETAILED DESCRIPTION

[0025] Illustrative embodiments of the present disclosure are described with reference to the accompanying drawings.

[0026] <First Embodiment>

[0027] 1. Configuration of cable 1

[0028] based on Figure 1-2 The structure of the cable 1 is described. It should be noted that the cable 1 is used for manufacturing the terminal processing cable 3 described later. Figure 1 As shown, the cable 1 is a linear member. Figure 2 It is a cross-sectional view of the cable 1 in a cross section perpendicular to the longitudinal direction of the cable 1 .

[0029] like Figure 2As shown, the cable 1 includes a first electric wire 5A, a second electric wire 5B, a third electric wire 5C, a fourth electric wire 5D, a fifth electric wire 5E, a sixth electric wire 5F, a seventh electric wire 5G, and an eighth electric wire 5H. Hereinafter, these may be collectively referred to as a plurality of electric wires 5.

[0030] The first electric wire 5A includes a conductor 11 and an insulator 13. The insulator 13 covers the conductor 11. The material of the conductor 11 is, for example, copper, copper alloy, aluminum, aluminum alloy, etc. The material of the insulator 13 is, for example, polyethylene, etc. The second electric wire 5B, the third electric wire 5C, the fourth electric wire 5D, the fifth electric wire 5E, the sixth electric wire 5F, the seventh electric wire 5G, and the eighth electric wire 5H also have the same structure as the first electric wire 5A.

[0031] The first wire 5A and the second wire 5B are sub-twisted to form a wire pair 6AB. The third wire 5C and the fourth wire 5D are sub-twisted to form a wire pair 6CD. The fifth wire 5E and the sixth wire 5F are sub-twisted to form a wire pair 6EF. The seventh wire 5G and the eighth wire 5H are sub-twisted to form a wire pair 6GH. The wire pair 6AB, the wire pair 6CD, the wire pair 6EF, and the wire pair 6GH are mother-twisted.

[0032] The cable 1 includes a press-wound portion 15. The press-wound portion 15 is a tape wound around the outer circumference of the plurality of electric wires 5. The press-wound portion 15 is an insulating member. The press-wound portion 15 is wound in a spiral shape, for example. The inner circumference of the press-wound portion 15 is in contact with the outer circumference of the plurality of electric wires 5.

[0033] The cable 1 includes a drain wire 17. The drain wire 17 is located on the outer peripheral side of the pressing winding portion 15. The drain wire 17 is in contact with the outer peripheral surface of the pressing winding portion 15. The drain wire 17 includes copper or a copper alloy. The drain wire 17 is, for example, made of copper or a copper alloy. The drain wire 17 is, for example, a tinned copper wire. The tinned copper wire includes a main body portion made of copper or a copper alloy and a tin-plated layer formed on the outer peripheral surface of the main body portion.

[0034] The cable 1 includes a braided shield 19. The braided shield 19 includes aluminum or an aluminum alloy. The braided shield 19 is made of, for example, aluminum or an aluminum alloy. The braided shield 19 is made by braiding metal wires. The material of the metal wires is, for example, aluminum or an aluminum alloy.

[0035] The braided shield 19 is provided on the outer peripheral sides of the plurality of electric wires 5, the press-wound portion 15, and the drain wire 17. The inner peripheral surface of the braided shield 19 contacts the outer peripheral surfaces of the drain wire 17 and the press-wound portion 15. The braided shield 19 and the drain wire 17 are electrically connected.

[0036] The cable 1 includes a sheath 21. The sheath 21 is provided on the outer peripheral side of the braided shield 19. The inner peripheral surface of the sheath 21 is in contact with the outer peripheral surface of the braided shield 19. The sheath 21 is made of, for example, thermoplastic polyurethane.

[0037] 2. Method for manufacturing terminal-processed cable 3 and cable 23 with connector

[0038] based on Figure 3A to Figure 3D , Figure 4A to Figure 4D , Figure 5 as well as Figure 6 A method for manufacturing the terminal-processed cable 3 and the cable with connector 23 will be described.

[0039] like Figure 3A As shown, the cable 1 is prepared. The jacket 21 is removed at the end 25 of the cable 1. At the end 25, the braided shield 19 is exposed.

[0040] Then, if Figure 3B As shown in FIG. 1 , the braided shield 19 at the end 25 is untied. The untied braided shield 19 is hereinafter referred to as the braided shield 19A. The braided shield 19A is a collection of unwoven metal wires. The braided shield 19A is not woven, so as Figure 3B As shown, the drain wire 17 can be taken out to the outside of the braided shield 19A.

[0041] Next, Figure 3B The cut surface 28 shown cuts the braided shield 19A. The cut surface 28 is a plane perpendicular to the longitudinal direction of the braided shield 19A. The portion of the braided shield 19A closer to the front end than the cut surface 28 is removed. The braided shield 19A after cutting becomes shorter in the longitudinal direction of the cable 1 compared to the braided shield 19 before cutting.

[0042] Then, if Figure 3C As shown in FIG. 1 , the braided shield 19A is folded back on the adjacent portion 27 side and overlapped from the outer peripheral side to the adjacent portion 27. The adjacent portion 27 is a part of the cable 1, and is a part adjacent to the terminal 25 in the length direction of the cable 1. It should be noted that the sheath 21 is not removed in the adjacent portion 27. Therefore, the braided shield 19A overlapped on the adjacent portion 27 faces the outer peripheral surface of the sheath 21.

[0043] It should be noted that, in this specification, overlapping the second member on the first member from the outer peripheral side means that at least a portion of the first member overlaps at least a portion of the second member when viewed from the radial direction of the cable 1. The first member and the second member may be in direct contact or there may be another member between them.

[0044] Then, if Figure 3D As shown, an insulating tape 31 is wound from the outer circumference to the adjacent portion 27. The insulating tape 31 is a tape made of an insulating member. Examples of the insulating member include acetate and the like. The braided shield 19A overlapped on the adjacent portion 27 is covered by the insulating tape 31 from the outer circumference.

[0045] In addition, if Figure 3D As shown in FIG. 1 , the pressed winding portion 15 is removed from the terminal 25. As a result, the plurality of electric wires 5 are exposed at the terminal 25. Then, the sub-twisted and main-twisted of the exposed plurality of electric wires 5 are untwisted. As a result, the plurality of electric wires 5 are untwisted at the terminal 25. It should be noted that, in the present embodiment, the number of the plurality of electric wires 5 is 8, but in Figure 3D In order to avoid making the figure complicated, only four are shown. Figure 4A to Figure 4D The same is true in Chinese.

[0046] Then, if Figure 4A As shown, a portion of the cable 1 is covered from the outer peripheral side by a heat shrink tube 33. The range covered by the heat shrink tube 33 includes a portion of the terminal 25 and the adjacent portion 27. The vicinity of the boundary between the terminal 25 and the adjacent portion 27 is covered by the heat shrink tube 33. The front end portion 25A, which is a portion on the front end side of the terminal 25, is not covered by the heat shrink tube 33. At the front end portion 25A, the plurality of electric wires 5 and the drain wire 17 are not covered by the heat shrink tube 33 and are exposed.

[0047] The range covered by the heat shrink tube 33 includes the insulating tape 31. The insulating tape 31 covers the braided shield 19A. Therefore, the heat shrink tube 33 covers the range including the braided shield 19A.

[0048] The heat shrink tube 33 is made of, for example, polyolefin resin. After the heat shrink tube 33 covers a portion of the cable 1, the heat shrink tube 33 is heated to shrink. The heat shrink tube 33 is in close contact with the outer peripheral surface of a portion of the cable 1.

[0049] Then, if Figure 4B As shown, an insulating tape 35 is wound around a portion of the portion of the terminal 25 covered by the heat shrink tube 33. The insulating tape 35 covers the heat shrink tube 33 from the outer peripheral side. The insulating tape 35 is a tape made of an insulating member. Examples of the insulating member include acetate and the like.

[0050] The drain wire 17 located at the front end portion 25A is cut at the cut surface 37. The portion of the drain wire 17 located on the front end side relative to the cut surface 37 is removed. The drain wire 17 after cutting is shorter than the drain wire 17 before cutting.

[0051] Then, if Figure 4C As shown, the drain wire 17 located at the front end portion 25A is folded back and overlapped with the insulating tape 35 from the outer peripheral side. The insulating tape 35 is located on the outer peripheral side of the heat shrink tube 33, so the folded back drain wire 17 overlaps with the heat shrink tube 33 from the outer peripheral side. The folded back position of the drain wire 17 is near the boundary between the portion covered by the heat shrink tube 33 and the front end portion 25A.

[0052] Then, if Figure 4C As shown, the metal tape 39 is wound from the outer peripheral side around the insulating tape 35 and the drain wire 17 overlapped with the insulating tape 35. The insulating tape 35 is located on the outer peripheral side of the heat shrink tube 33, so the metal tape 39 is wound from the outer peripheral side around the heat shrink tube 33 and the drain wire 17. The inner peripheral surface of the metal tape 39 is in contact with the outer peripheral surface of the insulating tape 35 and the drain wire 17. The metal tape 39 is electrically connected to the drain wire 17.

[0053] In addition, if Figure 4C As shown, terminals 41 are attached to the front end portions 43 of the plurality of electric wires 5 . Figure 5 The state where the terminal 41 is attached to the front end portion 43 of the first electric wire 5A is shown. At the front end portion 43, the insulator 13 is removed and the conductor 11 is exposed.

[0054] The terminal 41 includes a rod-shaped terminal tip 44 and a crimping portion 45. The terminal tip 44 and the crimping portion 45 are arranged along the length direction of the terminal 41. The crimping portion 45 includes a body portion 47, two first claws 48, and two second claws 49.

[0055] The two first claws 48 extend from both ends of the body 47 in the width direction and face each other. The two second claws 49 extend from both ends of the body 47 in the width direction and face each other. In the length direction of the terminal 41, the two first claws 48 are located closer to the terminal front end 44 than the two second claws 49.

[0056] The main body 47 and the two first claws 48 hold the front end 43 from the outer peripheral side. The main body 47 and the two first claws 48 are crimped to the front end 43 by a crimping machine.

[0057] The main body 47 and the two second claws 49 hold the adjacent portion 50 of the first electric wire 5A from the outer peripheral side. The adjacent portion 50 is a portion of the first electric wire 5A adjacent to the front end portion 43. The main body 47 and the two second claws 49 are crimped to the adjacent portion 50 by a crimping machine.

[0058] The terminal 41 is electrically connected to the conductor 11. As with the first wire 5A, the second wire 5B, the third wire 5C, the fourth wire 5D, the fifth wire 5E, the sixth wire 5F, the seventh wire 5G, and the eighth wire 5H are also provided with the terminal 41 at the front end portion 43. Through the above steps, the terminal processing cable 3 is completed.

[0059] It should be noted that, below, the terminals 41 installed on the first wire 5A, the second wire 5B, the third wire 5C, the fourth wire 5D, the fifth wire 5E, the sixth wire 5F, the seventh wire 5G and the eighth wire 5H are respectively set as terminals 41A, 41B, 41C, 41D, 41E, 41F, 41G, and 41H.

[0060] Then, if Figure 4D As shown, the connector 51 is mounted on the terminal 25. The connector 51 is a hollow box-shaped member. The terminal 25 is inserted into the connector 51 from one side surface 53 of the connector 51.

[0061] A clamp 55 is mounted on the inner wall 57 of the connector 51. The terminal 25 is fixed to the connector 51 by being clamped between the clamp 55 and the inner wall 57. The clamp 55 contacts the portion of the terminal 25 around which the metal tape 39 is wound. The clamp 55 presses the drain wire 17 via the metal tape 39. The clamp 55 and the inner wall 57 are conductive members. The drain wire 17 is electrically connected to the inner wall 57 via the metal tape 39 and the clamp 55. The inner wall 57 corresponds to a grounding member.

[0062] The connector 51 has a side surface 59. The side surface 59 is opposite to the side surface 53. Figure 6 As shown, holes 61A, 61B, 61C, 61D, 61E, 61F, 61G, and 61H are formed on the side surface 59. Terminals 41A, 41B, 41C, 41D, 41E, 41F, 41G, and 41H are inserted into the holes 61A, 61B, 61C, 61D, 61E, 61F, 61G, and 61H, respectively. Through the above steps, the cable 23 with a connector is completed.

[0063] 3. Effects of the terminal-processed cable 3 and the cable with connector 23

[0064] (1A) The terminal processing cable 3 and the cable with connector 23 are provided with the drain wire 17, so the drain wire 17 can be electrically connected to the ground member. Therefore, it is not necessary to directly electrically connect the braided shield 19 to the ground member. As a result, even if the braided shield 19 is made of aluminum or an aluminum alloy and the ground member is made of copper or nickel, galvanic corrosion between the braided shield 19 and the ground member can be suppressed.

[0065] (1B) Figure 4A As shown, in the terminal processing cable 3, the heat shrink tube 33 covers the area including the braided shield 19A in the cable 1. Therefore, the braided shield 19A can be prevented from coming into contact with moisture and corroding. The cable 23 with connector including the terminal processing cable 3 also has the same effect.

[0066] (1C) Figure 3D As shown, in the terminal processing cable 3, the braided shield 19A overlapping the adjacent portion 27 is covered with the insulating tape 31. Therefore, it is possible to suppress the braided shield 19A from piercing the sheath 21 of the adjacent portion 27. The cable 23 with connector provided with the terminal processing cable 3 also has the same effect.

[0067] (1D) Figure 4B , Figure 4C As shown, in the terminal processing cable 3, the drain wire 17 located at the terminal 25 is folded back and overlapped from the outer peripheral side to the portion located at the terminal 25 in the heat shrink tube 33. Furthermore, a metal tape 39 is wound from the outer peripheral side around the heat shrink tube 33 and the drain wire 17. For example, by electrically connecting the metal tape 39 to the grounding member, the drain wire 17 can be electrically connected to the grounding member.

[0068] (1E) Figure 4B As shown in FIG. 1 , when manufacturing the terminal processed cable 3, a portion of the front end side of the drain wire 17 is cut off. Figure 4C As shown, when the metal tape 39 is wound around the drain wire 17 from the outer peripheral side, it is possible to suppress the drain wire 17 from protruding to the outside of the metal tape 39 .

[0069] (1F) Figure 4D As shown, the clamp 55 presses the drain wire 17 via the metal tape 39. Therefore, the metal tape 39 and the drain wire 17 can be electrically connected stably.

[0070] (1G) Figure 3B , Figure 3C As shown, when manufacturing the terminal processing cable 3 , the front end side portion of the braided shield 19A is cut away. Therefore, it is possible to further suppress the braided shield 19A overlapping the adjacent portion 27 from piercing the sheath 21 of the adjacent portion 27 .

[0071] (1H) Figure 4B As shown, when manufacturing the terminal processing cable 3, the insulating tape 35 is wound around a portion of the portion covered by the heat shrink tube 33 in the terminal 25. The portion around which the insulating tape 35 is wound is the portion that is later held by the clamp 55. By winding the insulating tape 35, it is possible to suppress the generation of a gap between the inner peripheral surface of the clamp 55 and the outer peripheral surface of the terminal processing cable 3.

[0072] <Second Embodiment>

[0073] 1. Differences from the first embodiment

[0074] The basic structure of the second embodiment is the same as that of the first embodiment, so the differences are described below. It should be noted that the same reference numerals as those of the first embodiment represent the same structures, and reference is made to the previous description.

[0075] In the first embodiment described above, when manufacturing the terminal processed cable 3, Figure 3A to Figure 3D as well as Figures 4A to 4C In contrast, in the second embodiment, when manufacturing the terminal processed cable 3, Figure 3A to Figure 3D as well as Figure 4A The status shown, but not through Figures 4B to 4CThe state shown in FIG. 1 is different from the first embodiment in this respect. In the second embodiment, Figure 4A At the moment of the state shown, the terminal processing of the cable 3 is completed.

[0076] In the second embodiment, the cable 23 with a connector is manufactured as follows. Figure 4A After the state shown, the terminal 41 is mounted on the front end portion 43 of each of the plurality of electric wires 5. In addition, the terminal 41 is also mounted on the front end of the drain wire 17. Hereinafter, the terminal 41 mounted on the front end of the drain wire 17 is referred to as the terminal 41X. The configuration of the terminal 41 and the mounting method of the terminal 41 are the same as those of the first embodiment.

[0077] Then, if Figure 7 As shown in FIG. 2 , the connector 51 is mounted on the terminal 25. The configuration of the connector 51 and the method of mounting the connector 51 on the terminal 25 are basically the same as those of the first embodiment. Figure 8 As shown in FIG. 1 , in addition to the holes 61A, 61B, 61C, 61D, 61E, 61F, 61G, and 61H, a hole 61X is formed on the side surface 59. As in the first embodiment, the terminals 41A, 41B, 41C, 41D, 41E, 41F, 41G, and 41H are respectively inserted into the holes 61A, 61B, 61C, 61D, 61E, 61F, 61G, and 61H. The terminal 41X is inserted into the hole 61X. Through the above process, the cable 23 with a connector is completed.
