Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, as the terminal of the wire with a terminal as described above, there is one in which the terminal intermediate portion has a bent portion, and the extending direction of the core wire connection portion intersects with the extending direction of the mating-side connection portion. In this case, for example, if the distance from the tip of the core wire to the bent portion is short, there is a problem that the water-stopping property is reduced because the range covered by the shrink tube becomes short. Further, for example, if the position of the tip of the core wire is simply moved away from the bent portion in order to increase the range covered by the shrink tube, the position of the core wire connection portion moves away from the mating-side connection portion, and it may become impossible to cope with the mounting space.

[0005] The purpose of this disclosure is to provide a wire with a terminal that can improve watertightness while suppressing deterioration of installation space conditions, and a method for manufacturing a wire with a terminal. [Means for solving the problem]

[0006] The wire with a terminal of the present disclosure comprises a wire having a core wire and an insulating coating covering the core wire, a terminal connected to the core wire exposed from the insulating coating, and a heat shrink tube having an adhesive on its inner surface and covering the connection portion between the core wire and the terminal, wherein the terminal is formed in a plate shape having a first main surface and a second main surface, and has a core wire connection portion that extends along the axis of the wire and to which the core wire is connected, a mating connection portion that extends along a cross axis intersecting the axis of the wire and is connected to a mating member, and the core wire connection The connector has a terminal intermediate portion that connects the core wire connection portion and the mating connector portion, the terminal intermediate portion having a first bent portion that bends from the end of the core wire connection portion so that the first main surface becomes the outer surface, a cross extension portion that extends from the first bent portion along the cross axis, a second bent portion that bends from the tip of the cross extension portion so that the first main surface becomes the outer surface, a folded extension portion that extends from the second bent portion along the axis of the electric wire, and a third bent portion that bends from the tip of the folded extension portion so that the second main surface becomes the outer surface and connects to the base end of the mating connector portion. [Effects of the Invention]

[0007] According to the wire with terminals and the method for manufacturing the wire with terminals of this disclosure, watertightness can be improved while suppressing deterioration of the installation space conditions. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 is a partial cross-sectional view of a wire with terminals in the process of being manufactured in one embodiment. [Figure 2] Figure 2 is a plan view of a wire with terminals in the process of being manufactured in one embodiment. [Figure 3] Figure 3 is a partial cross-sectional view of a wire with terminals in one embodiment. [Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. [1] The wire with a terminal of the present disclosure comprises a wire having a core wire and an insulating coating covering the core wire, a terminal connected to the core wire exposed from the insulating coating, and a heat shrink tube having an adhesive on its inner surface and covering the connection portion between the core wire and the terminal, wherein the terminal is formed in a plate shape having a first main surface and a second main surface, and has a core wire connection portion that extends along the axis of the wire and to which the core wire is connected, a mating connection portion that extends along a cross axis intersecting the axis of the wire and is connected to a mating member, and the core wire connection The terminal has an intermediate terminal portion that connects the connecting portion and the mating connecting portion, the intermediate terminal portion having a first bent portion that bends from the end of the core wire connecting portion so that the first main surface becomes the outer surface, a cross extension portion that extends from the first bent portion along the cross axis, a second bent portion that bends from the tip of the cross extension portion so that the first main surface becomes the outer surface, a folded extension portion that extends from the second bent portion along the axis of the electric wire, and a third bent portion that bends from the tip of the folded extension portion so that the second main surface becomes the outer surface and connects to the base end of the mating connecting portion.

[0010] According to this configuration, the terminal's intermediate section has a first bend, a cross extension, a second bend, a folded extension, and a third bend. This allows the distance from the tip of the core wire to the first bend to be increased while preventing the core wire connection from moving too far away from the mating connection. Therefore, the area covered by the heat shrink tubing can be extended sufficiently towards the tip of the core wire. This allows for high watertightness while minimizing deterioration of the mounting space. In other words, if the core wire connection is moved too far away from the mating connection, it may not be possible to accommodate the mounting space, but this can be prevented, thus minimizing deterioration of the mounting space. Furthermore, since the linear distance from the tip of the core wire to the first bend can be increased, the area covered by the heat shrink tubing can be extended sufficiently towards the tip of the core wire. Therefore, compared to the case where the area covered by the heat shrink tubing is short towards the tip of the core wire 21, watertightness can be increased.

[0011] [2] In the above [1], the heat shrink tube may be positioned such that its end abuts against the cross extension. With this configuration, since the end of the heat-shrink tubing abuts against the cross extension, the position of the heat-shrink tubing is stabilized, and consequently, the area covered by the heat-shrink tubing can be stably and sufficiently long towards the tip of the core wire. In other words, in a configuration where the end of the heat-shrink tubing is not positioned to abut against the cross extension, the position of the heat-shrink tubing becomes unstable, and consequently, the area covered by the heat-shrink tubing may become shorter towards the tip of the core wire, but this can be avoided. Therefore, the watertightness can be stably and highly improved.

[0012] [3] In the above [1] or [2], the core wire may be arranged on the first main surface of the core wire connection portion and connected to the core wire connection portion. According to this configuration, the core wire is positioned on the first main surface of the core wire connection portion and connected to the core wire connection portion. Therefore, for example, a large space can be secured on the second main surface side of the core wire connection portion. Thus, for example, it is possible to prevent the portion including the core wire from overlapping with the arrangement space of the mating member to which the mating connection portion is connected.

[0013] [4] In any one of the above [1] to [3], the heat shrink tube may have an overlap portion that extends along the axis of the electric wire and has a constant distance from the first main surface and from the second main surface.

[0014] According to this configuration, the heat-shrinkable tube has an overlapping portion that extends along the axis of the electric wire, with a constant distance from the first main surface and a constant distance from the second main surface. Therefore, both the watertightness along the first main surface and the watertightness along the second main surface can be made high.

[0015] [5] The method for manufacturing a wire with a terminal according to the present disclosure is the method for manufacturing a wire with a terminal according to [1] above, comprising: an arrangement step of arranging the heat shrink tube, which has the adhesive disposed on its inner surface before shrinking, so that its end abuts against the cross extension; and a shrinking step of shrinking the heat shrink tube after the arrangement step.

[0016] According to this method, since the end of the heat-shrink tubing abuts against the cross extension, the position of the heat-shrink tubing is stabilized, and consequently, the area covered by the heat-shrink tubing can be stably and sufficiently long towards the tip of the core wire. In other words, in a configuration where the end of the heat-shrink tubing is not positioned to abut against the cross extension, the position of the heat-shrink tubing becomes unstable, and consequently, the area covered by the heat-shrink tubing may become shorter towards the tip of the core wire, but this can be avoided. Therefore, watertightness can be stably and significantly increased with a simple method.

[0017] [Details of the embodiments of this disclosure] Specific examples of the terminal-equipped wires described herein will be explained below with reference to the drawings. In each drawing, some parts of the configuration may be exaggerated or simplified for the sake of explanation. Also, the dimensional ratios of each part may differ in each drawing.

[0018] As used in the description of this specification, the term "tubular" includes not only those with a continuous peripheral wall formed over the entire circumference in the circumferential direction, but also those formed by combining multiple components into a tubular shape, and those with a notch or the like in a part of the circumferential direction such as a C shape. The outer peripheral shape of the "tubular" includes, but is not limited to, a circular shape, an elliptical shape, and a polygon with pointed or rounded corners. The "tubular" is a shape having a through-hole in a plan view, and includes those in which the outer peripheral shape and the inner peripheral shape of the through-hole are the same shape, and those in which the outer peripheral shape and the inner peripheral shape of the through-hole are different shapes. The "tubular" includes those having a predetermined length extending along the axial direction in which the central axis passing through the center of the through-hole extends, regardless of the size of the length.

[0019] In this specification, the terms "right angle" and "constant" include not only cases of exactly right angles and constants, but also cases that are generally right angles and generally constants within the scope where the effects of this embodiment are achieved. The terms such as "first", "second", "third", etc. in this specification are merely used to distinguish objects and do not rank the objects.

[0020] Note that the present invention is not limited to these examples, and is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0021] (Configuration of the wire 10 with terminals) As shown in FIGS. 1 to 3, the wire 10 with terminals includes a wire 20, a terminal 30, and a shrink tube 40. Note that FIGS. 1 and 2 show the wire 10 with terminals during manufacturing, and FIG. 3 shows the wire 10 with terminals after manufacturing is completed.

[0022] (Configuration of the wire 20) The wire 20 has a conductive core wire 21 and an insulating coating 22 covering the core wire 21.

[0023] As the core wire 21, for example, a stranded wire made by twisting together multiple metal strands, or a columnar conductor consisting of a single columnar metal rod with a solid internal structure can be used. As the constituent material of the core wire 21, for example, metal materials such as copper-based or aluminum-based materials can be used.

[0024] The insulating coating 22 covers the outer surface of the core wire 21 around its entire circumference. The insulating coating 22 is made of an insulating material, such as a synthetic resin. As the constituent material of the insulating coating 22, for example, a synthetic resin mainly composed of polyolefin resins such as cross-linked polyethylene or cross-linked polypropylene can be used. The ends of the core wire 21 in the longitudinal direction are exposed from the insulating coating 22.

[0025] (Configuration of terminal 30) The terminal 30 is connected to the core wire 21 exposed from the insulating coating 22. The terminal 30 is formed in a plate shape having a first main surface 31 and a second main surface 32 opposite to the first main surface 31. In other words, the terminal 30 is formed by processing a metal plate material. As the constituent material of the terminal 30, for example, metal materials such as copper-based or aluminum-based materials can be used.

[0026] The terminal 30 has a core wire connection portion 33, a mating side connection portion 34, and a terminal intermediate portion 35. The core wire connection portion 33 extends along the axis L of the electric wire 20, to which the core wire 21 is connected. The axis L of the electric wire 20 referred to here is the axis L of the electric wire 20 at the portion connected to the terminal 30. The mating side connection portion 34 extends along a cross axis X that intersects the axis L of the electric wire 20, and is connected to, for example, a terminal block 50 (see Figure 3) as a mating component. The terminal intermediate portion 35 is provided to connect the core wire connection portion 33 and the mating side connection portion 34.

[0027] The core wire connection portion 33 of this embodiment has a coating crimping portion 33a and a core wire crimping portion 33b. The coating crimping portion 33a is crimped so as to surround the insulating coating 22 and hold the insulating coating 22 inward. The core wire crimping portion 33b is crimped so as to surround the core wire 21 and hold the core wire 21 inward. As a result, the core wire connection portion 33 is electrically and mechanically connected to the core wire 21.

[0028] Furthermore, in this embodiment, the core wire 21 is positioned on the first main surface 31 of the core wire connection portion 33 and connected to the core wire connection portion 33. That is, the core wire crimping portion 33b is crimped on the first main surface 31 of the core wire connection portion 33 so as to surround the core wire 21 and hold the core wire 21 inward.

[0029] The mating connector 34 has a connection hole 34a. As shown in Figure 3, the mating connector 34 is electrically connected to the terminal block 50 while being fastened to it by a bolt 51 that passes through the connection hole 34a.

[0030] As shown in Figures 1 and 3, the terminal intermediate portion 35 has a first bent portion 35a, a cross extension portion 35b, a second bent portion 35c, a folded extension portion 35d, and a third bent portion 35e. The first bent portion 35a is bent from the end of the core wire connection portion 33 so that the first main surface 31 is the outer surface. The cross extension portion 35b extends from the first bent portion 35a along the cross axis X.

[0031] Furthermore, the second bent portion 35c is bent from the tip of the intersecting extension portion 35b so that the first main surface 31 is the outer surface. The folded extension portion 35d extends from the second bent portion 35c along the axis L of the electric wire 20. The third bent portion 35e is bent from the tip of the folded extension portion 35d so that the second main surface 32 is the outer surface, and is connected to the base end of the mating connection portion 34. Note that the first bent portion 35a, the second bent portion 35c, and the third bent portion 35e in this embodiment are each bent at a right angle.

[0032] (Composition of heat shrink tubing 40) The heat-shrinkable tube 40 is formed in a cylindrical shape, with adhesive 41 placed on its inner circumference, and is provided to cover the connection portion between the core wire 21 and the terminal 30. More specifically, the heat-shrinkable tube 40 is a heat-shrinkable tube that has the property of shrinking when heated. Examples of constituent materials for the heat-shrinkable tube 40 include polyolefin resin, fluoropolymer, and thermoplastic elastomer. Examples of constituent materials for the adhesive 41 include hot melt adhesives that melt when heated and solidify when cooled.

[0033] As shown in Figure 1, the heat-shrinkable tube 40 before heating and before shrinkage is formed in a cylindrical shape. Also, before heating and before shrinkage, adhesive 41 is evenly distributed on the inner surface of the heat-shrinkable tube 40.

[0034] Furthermore, as shown in Figure 3, the heat-shrinkable tube 40, after being heated and shrunk, is positioned so that its end abuts against the cross extension portion 35b. More precisely, the heat-shrinkable tube 40, after being heated and shrunk, is positioned so that its end abuts against the cross extension portion 35b via the adhesive 41. Also, the heat-shrinkable tube 40, after being heated and shrunk, is positioned to cover the end of the insulating coating 22, including the crimped coating portion 33a.

[0035] Furthermore, after heating and shrinking, the heat-shrinkable tube 40 has an overlapping portion 40a that extends along the axis L of the electric wire 20, with a constant distance from the first main surface 31 and the second main surface 32. Figure 3 illustrates the range Z of the overlapping portion 40a in the heat-shrinkable tube 40. In addition, the adhesive 41 in the heated state of the heat-shrinkable tube 40 is arranged to fill the gap inside the heat-shrinkable tube 40.

[0036] (Manufacturing method for wire with terminals 10) Next, the manufacturing method of the terminal-equipped electric wire 10 and its operation will be described. The manufacturing method for the terminal-equipped electric wire 10 configured as described above comprises an arrangement step and a shrinking step.

[0037] In the placement process, as shown in Figure 1, the pre-shrinkage heat-shrinkable tube 40, on which adhesive 41 has been placed on its inner surface, is positioned to cover the connection area between the core wire 21 and the terminal 30, while ensuring that the end of the heat-shrinkable tube 40 abuts against the cross extension 35b.

[0038] Next, in the shrinkage process, the shrinkage tube 40 is heated to shrink it from the state shown in Figure 1 to the state shown in Figure 3. At this time, the adhesive 41 is temporarily melted and positioned to fill the gaps inside the shrinkage tube 40. In this way, the manufacturing of the terminal-equipped electric wire 10 is completed.

[0039] In the terminal-equipped electric wire 10 configured in this way, the heat-shrink tubing 40 and adhesive 41 prevent water from reaching the core wire connection part 33 and the core wire 21. Therefore, corrosion at the connection point between the core wire connection part 33 and the core wire 21 is suppressed, for example.

[0040] (Effects of this embodiment) Next, the effects of the above embodiment are described below. (1) The terminal intermediate portion 35 has a first bend portion 35a, a cross extension portion 35b, a second bend portion 35c, a folded extension portion 35d, and a third bend portion 35e. Therefore, the distance from the tip of the core wire 21 to the first bend portion 35a can be increased while preventing the position of the core wire connection portion 33 from moving away from the mating connection portion 34 (to the right in Figure 3). Therefore, the area covered by the heat shrink tube 40 can be made sufficiently long towards the tip of the core wire 21. This makes it possible to increase watertightness while suppressing deterioration of the mounting space conditions. In other words, if the position of the core wire connection portion 33 moves away from the mating connection portion 34 (to the right in Figure 3), there is a risk that it will not be able to accommodate the mounting space, but this can be suppressed, so deterioration of the mounting space conditions can be suppressed. Also, since the linear distance from the tip of the core wire 21 to the first bend portion 35a can be increased, the area covered by the heat shrink tube 40 can be made sufficiently long towards the tip of the core wire 21. Therefore, compared to the case where the area covered by the heat-shrinkable tube 40 is shorter towards the tip of the core wire 21, the watertightness can be improved.

[0041] Furthermore, the terminal intermediate section 35, which has a first bent section 35a, a crossing extension section 35b, a second bent section 35c, a folded extension section 35d, and a third bent section 35e, prevents the adhesive 41 from reaching the mating connection section 34. In other words, although the molten adhesive 41 may try to flow toward the mating connection section 34, the complex shape of the terminal intermediate section 35 prevents this adhesive 41 from reaching the mating connection section 34. As a result, for example, the adhesive 41 is prevented from obstructing the connection of the mating connection section 34 to the terminal block 50.

[0042] (2) Since the end of the heat-shrink tube 40 is positioned so as to abut against the cross extension 35b, the position of the heat-shrink tube 40 is stabilized, and consequently, the area covered by the heat-shrink tube 40 can be stably and sufficiently long towards the tip of the core wire 21. In other words, in a configuration in which the end of the heat-shrink tube 40 is not positioned so as to abut against the cross extension 35b, the position of the heat-shrink tube 40 becomes unstable, and consequently, the area covered by the heat-shrink tube 40 may become shorter towards the tip of the core wire 21, but this can be avoided. Therefore, the watertightness can be stably and highly improved.

[0043] (3) Since the core wire 21 is positioned on the first main surface 31 of the core wire connection portion 33 and connected to the core wire connection portion 33, for example, a large space can be secured on the second main surface 32 side of the core wire connection portion 33. Therefore, for example, it is possible to prevent the portion including the core wire 21 from overlapping with the arrangement space of the terminal block 50, which is the mating member to which the mating connection portion 34 is connected.

[0044] (4) Since the heat shrink tube 40 has an overlap portion 40a that extends along the axis L of the electric wire 20 and has a constant distance from the first main surface 31 and the second main surface 32, it is possible to achieve high watertightness along both the first main surface 31 and the second main surface 32.

[0045] (5) In the arrangement step of the manufacturing method of the terminal-equipped electric wire 10, the heat-shrink tubing 40 is positioned so that its end abuts against the cross extension 35b. As a result, the position of the heat-shrink tubing 40 is stabilized, and consequently, the area covered by the heat-shrink tubing 40 can be made stably and sufficiently long towards the tip of the core wire 21. In other words, in a configuration in which the end of the heat-shrink tubing 40 is not positioned abuts against the cross extension 35b, the position of the heat-shrink tubing 40 becomes unstable, and consequently, the area covered by the heat-shrink tubing 40 may become shorter towards the tip of the core wire 21, but this can be avoided. As a result, watertightness can be stably and highly improved in a simple manner.

[0046] (Example of change) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0047] In the above embodiment, the heat-shrinkable tube 40 is positioned so that its end abuts against the intersecting extension 35b, but this is not limited to this configuration. For example, the end of the heat-shrinkable tube 40 may be separated from the intersecting extension 35b. That is, a gap may be provided between the end of the heat-shrinkable tube 40 and the intersecting extension 35b.

[0048] In the above embodiment, the core wire 21 is positioned on the first main surface 31 of the core wire connection portion 33 and connected to the core wire connection portion 33, but the embodiment is not limited to this. For example, the core wire 21 may be positioned on the second main surface 32 of the core wire connection portion 33 (the lower side of the second main surface 32 in Figure 3) and connected to the core wire connection portion 33. That is, the core wire 21 may be positioned on the side of the core wire connection portion 33 where the first bent portion 35a is bent and connected to the core wire connection portion 33.

[0049] In the above embodiment, the heat-shrinkable tube 40 is assumed to have an overlapping portion 40a that extends along the axis L of the electric wire 20, with a constant distance from the first main surface 31 and the second main surface 32. However, the invention is not limited to this, and a configuration without an overlapping portion 40a is also possible.

[0050] In the arrangement step of the manufacturing method for the terminal-equipped electric wire 10 of the above embodiment, the end of the heat-shrinkable tube 40 is arranged so that it abuts against the cross extension portion 35b, but the invention is not limited to this, and the end of the heat-shrinkable tube 40 may be arranged so that it does not abut against the cross extension portion 35b.

[0051] In the above embodiment, the core wire connection portion 33 is configured to have a coating crimp portion 33a and a core wire crimp portion 33b, but it is not limited to this configuration, and can be changed to any other configuration as long as the core wire 21 is connected.

[0052] In the above description and drawings of the embodiment, the terminal intermediate portion 35 is described as having a linearly extending cross extension portion 35b and a folded extension portion 35d when viewed from the side (see Figure 3), but is not limited thereto. For example, the core wire connection portion 33, the first bent portion 35a, the cross extension portion 35b, the second bent portion 35c, and the folded extension portion 35d are formed in a curved and folded U-shape, and the cross extension portion 35b does not have to extend linearly along the cross axis X.

[0053] The manufacturing method for the terminal-equipped wire 10 in the above embodiment may be changed to another manufacturing method if it is possible to manufacture a similar terminal-equipped wire 10. For example, in the arrangement step in the manufacturing method for the terminal-equipped wire 10, the end of the heat-shrinkable tube 40 is arranged to abut against the cross extension 35b, but the end of the heat-shrinkable tube 40 may be arranged so that it does not abut against the cross extension 35b.

[0054] The embodiments disclosed herein are illustrative in all respects, and the present invention is not limited to these examples. That is, the scope of the present invention is indicated by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
