Description

Technical Field

[0001] This invention relates to terminald wires and a method for manufacturing terminald wires. Background Technology

[0002] Conventionally, terminald wires include wires, terminals, and shrink tubes (see, for example, Patent Document 1). The wire has a core wire and an insulating cover that encloses the core wire. The terminal connects to the core wire exposed from the insulating cover. Specifically, the terminal is formed as a plate having a first main surface and a second main surface. The terminal has: a core wire connecting portion extending along the axis of the wire and connecting the core wire; a opposite-side connecting portion connecting to an opposite-side member; and a terminal middle portion connecting the core wire connecting portion and the opposite-side connecting portion. An adhesive is disposed on the inner circumferential surface of the shrink tube, covering the connection area between the core wire and the terminal. This prevents water immersion at the connection area between the core wire and the terminal.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2023-178648 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, as described above, some terminals of terminald wires have a bend in the middle of the terminal so that the direction in which the core wire connection extends intersects the direction in which the opposite-side connection extends. In this case, for example, when the distance from the tip of the core wire to the bend is short, there is a problem that the coverage area of ​​the shrink tube becomes shorter, resulting in reduced waterproofing. Furthermore, for example, if, in order to increase the coverage area of ​​the shrink tube, it is simply desired to move the tip of the core wire away from the bend, the position of the core wire connection relative to the opposite-side connection may not correspond to the installation space.

[0008] The purpose of this invention is to provide a terminal wire and a method for manufacturing a terminal wire that can improve water-stopping performance while suppressing the deterioration of installation space conditions.

[0009] Solution for solving the problem

[0010] The terminald wire of the present invention comprises: a wire having a core wire and an insulating cover portion covering the core wire; a terminal for connecting to the core wire exposed from the insulating cover portion; and a shrink tube having an adhesive disposed on its inner circumferential surface to cover the connection portion between the core wire and the terminal, the terminal having: a core wire connecting portion formed as a plate having a first main surface and a second main surface, extending along the axis of the wire and connecting to the core wire; a counter-side connecting portion extending along a cross axis intersecting the axis of the wire and connecting to a counter-side member; and a terminal intermediate portion connecting the core wire connecting portion and the terminal. The terminal middle portion of the opposite-side connection portion has: a first bending portion, which bends from the end of the core wire connection portion with the first main surface as the outer surface; a cross extension portion, which extends from the first bending portion along the cross axis; a second bending portion, which bends from the top of the cross extension portion with the first main surface as the outer surface; a fold-back extension portion, which extends from the second bending portion along the axis of the wire; and a third bending portion, which bends from the top of the fold-back extension portion with the second main surface as the outer surface, and is connected to the base end of the opposite-side connection portion.

[0016] (Description of embodiments of the present invention)

[0017] First, embodiments of the present invention will be described.

[0018] (1) The terminald wire of the present invention comprises: a wire having a core wire and an insulating cover portion covering the core wire; a terminal connected to the core wire exposed from the insulating cover portion; and a shrink tube having an adhesive disposed on its inner circumferential surface to cover the connection portion between the core wire and the terminal, the terminal having: a core wire connecting portion formed as a plate having a first main surface and a second main surface, extending along the axis of the wire and connecting to the core wire; a counter-side connecting portion extending along a cross axis intersecting the axis of the wire and connecting to a counter-side member; and a terminal intermediate portion connected to the core wire connecting portion. The terminal middle portion, in connection with the opposite side connection portion, has: a first bending portion, bent from the end of the core wire connection portion with the first main surface as the outer surface; a cross extension portion, extending from the first bending portion along the cross axis; a second bending portion, bent from the top of the cross extension portion with the first main surface as the outer surface; a fold-back extension portion, extending from the second bending portion along the axis of the wire; and a third bending portion, bent from the top of the fold-back extension portion with the second main surface as the outer surface, connected to the base end of the opposite side connection portion.

[0019] According to this structure, the middle portion of the terminal has a first bend, a cross extension, a second bend, a fold-back extension, and a third bend. Therefore, while preventing the position of the core wire connection portion from moving away from the opposite side connection portion, the distance from the tip of the core wire to the first bend portion can be increased. Thus, the area covered by the shrink tube on the tip side of the core wire can be sufficiently extended. Consequently, the water-stopping performance can be improved while suppressing the deterioration of the installation space conditions. That is, when the position of the core wire connection portion is far from the opposite side connection portion, it may not correspond to the installation space, but this situation can be suppressed, thus suppressing the deterioration of the installation space conditions. Furthermore, because the straight-line extension distance from the tip of the core wire to the first bend portion can be increased, the area covered by the shrink tube on the tip side of the core wire can be sufficiently extended. Therefore, compared to the case where the shrink tube coverage area is shorter on the tip side of the core wire 21, the water-stopping performance can be improved.

[0020] (2) In (1) above, the shrink tube may also be configured such that its end abuts against the cross extension.

[0021] According to this structure, the shrink tube is configured such that its end abuts against the cross extension, thus stabilizing its position and allowing the shrink tube to reliably and sufficiently extend its coverage area at the tip of the core wire. In contrast, in a structure where the end of the shrink tube is not abutted against the cross extension, the shrink tube's position becomes unstable, potentially shortening the coverage area at the tip of the core wire; however, this is avoided. Therefore, the water-stopping performance is consistently improved.

[0022] (3) In either (1) or (2) above, the core wire may be disposed on the first main surface of the core wire connection portion and connected to the core wire connection portion.

[0023] According to this structure, the core wire is disposed on the first main surface of the core wire connector and is connected to the core wire connector, thus ensuring, for example, a larger space on the second main surface side of the core wire connector. Therefore, for example, it can prevent the portion including the core wire from overlapping with the space of the opposite-side member connected as the opposite-side connector.

[0024] (4) In any of (1) to (3) above, the shrink tube may also have an overlapping portion that is constant in distance from the first main surface and from the second main surface and extends along the axis of the wire.

[0025] According to this structure, the shrink tube has an overlapping portion that is constant in distance from the first main surface and from the second main surface and extends along the axis of the wire, thereby improving the water-stopping performance along both the first and second main surfaces.

[0026] (5) The manufacturing method of the terminal wire of the present invention is the manufacturing method of the terminal wire of (1) above, comprising: a configuration step, wherein the shrink tube, on which the adhesive is disposed on the inner peripheral surface, is configured such that its end abuts against the cross extension; and a shrinking step, wherein the shrink tube is shrunk after the configuration step.

[0027] According to this method, the shrink tube is configured such that its end abuts against the cross extension, thus stabilizing its position and allowing the coverage area of ​​the shrink tube to be stably and sufficiently extended at the tip of the core wire. That is, in a structure where the end of the shrink tube is not abutted against the cross extension, the position of the shrink tube becomes unstable, and the coverage area of ​​the shrink tube may become shorter at the tip of the core wire, but this can be avoided. Therefore, the water-stopping performance can be stably improved using a simple method.

[0028] (Details of embodiments of the present invention)

[0029] Specific examples of the terminald wire of the present invention will be described below with reference to the accompanying drawings. In the drawings, for ease of explanation, some parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts may differ in the drawings.

[0030] The term "cylindrical" as used in this specification includes not only shapes with a continuous circumferential wall, but also shapes formed by combining multiple components, and shapes such as a C-shape with a notch in a portion of the circumference. The outer circumferential shape of a "cylindrical" includes, but is not limited to, circles, ellipses, and polygons with pointed or rounded corners. "Cylindrical" refers to a shape having a through hole when viewed from above, including cylinders with the same outer circumferential shape and the same inner circumferential shape as the through hole, or cylinders with different outer circumferential shapes and different inner circumferential shapes as the through hole. "Cylindrical" includes cylinders extending along an axial direction having a predetermined length, regardless of the magnitude of that length, where the axial direction is the direction extending from the central axis passing through the center of the through hole.

[0031] The terms "vertical" or "constant" in this specification include not only cases where the object is strictly vertical or constant, but also cases where the object is approximately vertical or approximately constant within the range that achieves the effect described in this embodiment. The terms "first," "second," "third," etc., used in this specification are only for distinguishing objects and do not constitute a ranking of the objects.

[0032] It should be noted that the present invention is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims as shown in the claims.

[0033] (Structure with terminal wire 10)

[0034] like Figures 1 to 3 As shown, the terminald wire 10 includes a wire 20, a terminal 30, and a shrink tube 40. It should be noted that... Figure 1 and Figure 2 This shows a terminald wire 10 during manufacturing. Figure 3 The completed terminal wire 10 is shown.

[0035] (Structure of wire 20)

[0036] The wire 20 has a core wire 21 and an insulating cover 22 covering the core wire 21, and the core wire 21 is conductive.

[0037] The core wire 21 can be, for example, a stranded wire made by twisting together multiple metal wires, or a columnar conductor made of a single metal rod with a solid internal structure. The constituent material of the core wire 21 can be, for example, copper-based or aluminum-based metal materials.

[0038] The insulating cover 22 covers the entire circumference of the outer periphery of the core wire 21, for example. The insulating cover 22 is made of an insulating material such as synthetic resin. For example, a synthetic resin with cross-linked polyethylene, cross-linked polypropylene, or other polyolefin resins as its main component can be used as the constituent material of the insulating cover 22. The longitudinal end of the core wire 21 protrudes from the insulating cover 22.

[0039] (Structure of terminal 30)

[0040] Terminal 30 is connected to the core wire 21 exposed from the insulating cover 22. Terminal 30 is formed as a plate having a first main surface 31 and a second main surface 32 opposite to the first main surface 31. In other words, terminal 30 is formed by processing a metal plate. As the constituent material of terminal 30, for example, copper-based, aluminum-based, or other metal materials can be used.

[0041] Terminal 30 has a core wire connecting portion 33, a counterpart connecting portion 34, and a terminal intermediate portion 35. The core wire connecting portion 33 extends along the axis L of the wire 20 and connects to the core wire 21. It should be noted that the axis L of the wire 20 referred to here is the axis L of the wire 20 at the portion where it connects to the terminal 30. The counterpart connecting portion 34 extends along a cross axis X that intersects the axis L of the wire 20, and connects, for example, to the terminal block 50 (see reference 50), which is a counterpart component. Figure 3 The terminal middle portion 35 is provided in such a way that it connects the core wire connection portion 33 and the opposite side connection portion 34.

[0042] The core wire connection portion 33 of this embodiment has a sheathing layer crimping portion 33a and a core wire crimping portion 33b. The sheathing layer crimping portion 33a is crimped in such a way that it surrounds the insulating cover portion 22 and holds the insulating cover portion 22 inside. In addition, the core wire crimping portion 33b is crimped in such a way that it surrounds the core wire 21 and holds the core wire 21 inside. Thus, the core wire connection portion 33 is electrically and mechanically connected to the core wire 21.

[0043] Furthermore, in this embodiment, the core wire 21 is disposed on the first main surface 31 of the core wire connecting portion 33 and connected to the core wire connecting portion 33. That is, the core wire crimping portion 33b crimps the core wire 21 on the first main surface 31 of the core wire connecting portion 33 in a manner that surrounds the core wire 21 and holds the core wire 21 inside.

[0044] The connecting part 34 on the opposite side has a connecting hole 34a. For example... Figure 3 As shown, the opposite-side connecting part 34 is fastened to the terminal block 50 by, for example, a bolt 51 passing through the connecting hole 34a and electrically connected to the terminal block 50.

[0045] like Figure 1 and Figure 3 As shown, the terminal middle portion 35 has a first bend portion 35a, a cross extension portion 35b, a second bend portion 35c, a fold-back extension portion 35d, and a third bend portion 35e. The first bend portion 35a bends from the end of the core wire connection portion 33 with the first main surface 31 as the outer surface. The cross extension portion 35b extends from the first bend portion 35a along the cross axis X.

[0046] Furthermore, the second bend 35c bends from the top of the cross extension 35b with the first main surface 31 as the outer surface. The fold-back extension 35d extends from the second bend 35c along the axis L of the wire 20. The third bend 35e bends from the top of the fold-back extension 35d with the second main surface 32 as the outer surface, and connects to the base end of the opposite-side connecting portion 34. It should be noted that in this embodiment, the first bend 35a, the second bend 35c, and the third bend 35e are each bent vertically.

[0047] (Structure of shrink tube 40)

[0048] The shrink tube 40 is formed in a cylindrical shape, and an adhesive 41 is disposed on its inner circumferential surface to cover the connection portion between the core wire 21 and the terminal 30. Specifically, the shrink tube 40 is, for example, a heat-shrink tube having the characteristic of shrinking upon heating. Examples of materials constituting the shrink tube 40 include polyolefin resins, fluoropolymers, and thermoplastic elastomers. Similarly, examples of materials constituting the adhesive 41 include hot melt adhesives that melt upon heating and solidify upon cooling.

[0049] like Figure 1 As shown, the shrink tube 40 before heating and shrinking is formed into a cylindrical shape. In addition, the shrink tube 40 before heating and shrinking has an adhesive 41 disposed on its inner circumferential surface with a uniform thickness.

[0050] In addition, such as Figure 3 As shown, the shrink tube 40, after being heated and shrunken, is configured such that its end abuts against the cross extension 35b. It should be noted that, strictly speaking, the shrink tube 40, after being heated and shrunken, is configured such that its end abuts against the cross extension 35b via adhesive 41. Furthermore, the shrink tube 40, after being heated and shrunken, is configured to cover the end of the insulating cover portion 22, including the covering layer press-fit portion 33a.

[0051] Furthermore, the shrink tube 40, after being heated and shrinking, has an overlapping portion 40a that extends along the axis L of the wire 20, with a constant distance from the first main surface 31 and from the second main surface 32. It should be noted that in... Figure 3 The diagram shows the extent of the overlapping portion 40a in the shrink tube 40. Furthermore, the adhesive 41 in the heated state of the shrink tube 40 is applied in a manner that fills the gaps on the inner side of the shrink tube 40.

[0052] (Manufacturing method of wire 10 with terminals)

[0053] Next, the manufacturing method of the terminal wire 10 and its function will be explained.

[0054] The manufacturing method of the terminal wire 10 constructed as described above includes a configuration step and a shrinking step.

[0055] In the configuration process, such as Figure 1 As shown, the shrink tube 40, on which adhesive 41 is disposed on the inner circumferential surface, is arranged to cover the connection portion of the core wire 21 and the terminal 30, and is arranged such that the end of the shrink tube 40 abuts against the cross extension 35b.

[0056] Next, in the shrinking process, the shrink tube 40 is shrunk by heating, causing the shrink tube 40 to shrink from the... Figure 1 The state shown becomes Figure 3 The state shown is as follows. At this time, the adhesive 41 is configured to temporarily melt and fill the gap inside the shrink tube 40. In this way, the manufacturing of the terminal wire 10 is completed.

[0057] In the terminald wire 10 constructed in this way, the shrink tubing 40 and adhesive 41 are used to prevent water immersion in the core wire connection portion 33 and the core wire 21. Therefore, corrosion of the connection points of the core wire connection portion 33 and the core wire 21 can be suppressed, for example.

[0058] (Effects of this implementation method)

[0059] Next, the effects of the above-described embodiments will be described.

[0060] (1) The terminal middle portion 35 has a first bend portion 35a, a cross extension portion 35b, a second bend portion 35c, a fold-back extension portion 35d, and a third bend portion 35e. Therefore, it is possible to suppress the position of the core wire connection portion 33 relative to the opposite side connection portion 34 (in Figure 3 While moving away from the center to the right, the distance from the top of the core wire 21 to the first bend 35a is lengthened. Therefore, the area covered by the contraction tube 40 can be sufficiently lengthened on the top side of the core wire 21. This improves water tightness while suppressing the deterioration of installation space conditions. That is, when the position of the core wire connection 33 relative to the opposite connection 34 (in...) Figure 3 When the wire moves away from the center (to the right), it may not correspond to the installation space, but this situation can be suppressed, thus preventing the deterioration of the installation space conditions. Furthermore, because the straight-line extension from the tip of the core wire 21 to the first bend 35a can be lengthened, the area covered by the contraction tube 40 can be sufficiently extended on the tip side of the core wire 21. Therefore, compared to the case where the area covered by the contraction tube 40 is shorter on the tip side of the core wire 21, the water-stopping performance can be improved.

[0061] Furthermore, the terminal intermediate portion 35, having a first bend 35a, a cross extension 35b, a second bend 35c, a fold-back extension 35d, and a third bend 35e, can prevent the adhesive 41 from reaching the counterpart connection portion 34. That is, the molten adhesive 41 may sometimes flow toward the counterpart connection portion 34, but the complex-shaped terminal intermediate portion 35 prevents the adhesive 41 from reaching the counterpart connection portion 34. Thus, for example, it can prevent the adhesive 41 from obstructing the connection with the terminal block 50 of the counterpart connection portion 34.

[0062] (2) The shrink tube 40 is configured such that its end abuts against the cross extension 35b, thus stabilizing the position of the shrink tube 40 and allowing the coverage area of ​​the shrink tube 40 to be stably extended at the top end of the core wire 21. That is, in a structure where the end of the shrink tube 40 is not abutted against the cross extension 35b, the position of the shrink tube 40 becomes unstable, and the coverage area of ​​the shrink tube 40 may become shorter at the top end of the core wire 21, but this situation can be avoided. Therefore, the water-stopping performance can be stably improved.

[0063] (3) The core wire 21 is disposed on the first main surface 31 of the core wire connection portion 33 and connected to the core wire connection portion 33. Therefore, for example, it can be ensured that the space on the second main surface 32 side of the core wire connection portion 33 is large. Therefore, for example, it can prevent the portion including the core wire 21 from overlapping with the arrangement space of the terminal block 50, which is connected as the counterpart side connection portion 34.

[0064] (4) The shrink tube 40 has an overlapping portion 40a that is constant at the distance to the first main surface 31 and the distance to the second main surface 32 and extends along the axis L of the wire 20, thereby improving the water-stopping properties along the first main surface 31 and the second main surface 32.

[0065] (5) In the configuration step of the manufacturing method of the terminal wire 10, the shrink tube 40 is configured such that its end abuts against the cross extension 35b. Therefore, the position of the shrink tube 40 becomes stable, and the coverage area of ​​the shrink tube 40 can be stably and sufficiently extended at the top end of the core wire 21. That is, in a structure in which the end of the shrink tube 40 is configured not to abut against the cross extension 35b, the position of the shrink tube 40 becomes unstable, and the coverage area of ​​the shrink tube 40 may become shorter at the top end of the core wire 21, but this situation can be avoided. Therefore, the water-stopping performance can be stably improved in a simple way.

[0066] (Modified example)

[0067] The above embodiments can be implemented with the following modifications. The above embodiments and the following variations can be combined with each other within the scope of technical inconsistency.

[0068] In the above embodiment, the shrink tube 40 is arranged such that its end abuts against the cross extension 35b, but this is not a limitation. For example, the end of the shrink tube 40 may also be away from the cross extension 35b. That is, it may also be configured such that a gap is provided between the end of the shrink tube 40 and the cross extension 35b.

[0069] In the above embodiment, the core wire 21 is disposed on the first main surface 31 of the core wire connecting portion 33 and connected to the core wire connecting portion 33, but is not limited thereto. For example, the core wire 21 may also be configured to be disposed on the second main surface 32 of the core wire connecting portion 33. Figure 3 (The second main surface 32 is located on the lower side) and connected to the core wire connection portion 33. That is, the core wire 21 can also be configured to be disposed in the core wire connection portion 33 on the side of the first bend 35a and connected to the core wire connection portion 33.

[0070] In the above embodiment, the shrink tube 40 has an overlapping portion 40a that is constant in distance from the first main surface 31 and from the second main surface 32 and extends along the axis L of the wire 20. However, it is not limited to this and may also be configured not to have the overlapping portion 40a.

[0071] In the configuration step of the manufacturing method of the terminal wire 10 in the above embodiment, the end of the shrink tube 40 is configured to abut against the cross extension 35b. However, it is not limited to this, and the end of the shrink tube 40 may also be configured not to abut against the cross extension 35b.

[0072] In the above embodiment, the core wire connection portion 33 is configured to have a covering layer crimping portion 33a and a core wire crimping portion 33b, but it is not limited to this. As long as it is a structure for connecting the core wire 21, it can be changed to other structures.

[0073] In the description and accompanying drawings of the above embodiments, it is shown that the middle portion 35 of the terminal is viewed from the side (see reference). Figure 3 It has a straight-line extending cross-extension 35b and a folded-back extension 35d, but is not limited thereto. For example, the core wire connecting portion 33, the first bend portion 35a, the cross-extension 35b, the second bend portion 35c, and the folded-back extension 35d may be formed into a curved folded-back U-shape, and the cross-extension 35b may not extend in a straight line along the cross axis X.

[0074] The manufacturing method of the terminal wire 10 described above can be modified to other manufacturing methods as long as the same terminal wire 10 can be manufactured. For example, in the arrangement step of the manufacturing method of the terminal wire 10, the end of the shrink tube 40 is arranged to abut against the cross extension 35b, but the end of the shrink tube 40 may also be arranged not to abut against the cross extension 35b.

[0075] The embodiments disclosed herein are illustrative in all respects, and the invention is not limited to these illustrative examples. That is, the scope of the invention is defined by the claims and is intended to include all modifications equivalent to and within the scope of the claims.
