[0011] Hereinafter, an embodiment of a vehicle window glass with a metal terminal will be described with reference to the accompanying drawings. However, the components described in the following embodiments are merely examples and do not limit the technical scope of the present invention. Furthermore, the dimensional relationships between the components shown in the drawings may not correspond to the actual dimensional relationships.

[0012] (metal terminal) A metal terminal to be attached to a vehicle window glass with a metal terminal will be described with reference to the drawings, in which Fig. 1 is a perspective view of the metal terminal, and Fig. 2 is a perspective view seen from a different direction from that of Fig. 1.

[0013] 1, metal terminal 10 includes a connecting portion 11, a first leg portion 12 connected to connecting portion 11, a first base portion 14 connected to first leg portion 12, a second leg portion 13 connected to connecting portion 11, and a second base portion 15 connected to second leg portion 13. First leg portion 12 and second leg portion 13 space connecting portion 11 from the conductor. Connecting portion 11 connects first leg portion 12, second leg portion 13, and conductor connection portion 16.

[0014] The first pedestal portion 14 and the second pedestal portion 15 are portions that are electrically connected via solder to a conductor formed on the glass plate. Two recesses 14A may be formed in the first pedestal portion 14. The recesses 14A cause the surface opposite to the surface on which the recesses 14A are formed to protrude. Similarly, two recesses 15A may be formed in the second pedestal portion 15. The recesses 15A cause the surface opposite to the surface on which the recesses 15A are formed to protrude.

[0015] The metal terminal 10 has a conductor connection portion 16 connected to the connecting portion 11 .

[0016] The conductor connection portion 16 includes a rising portion 16A connected to the connecting portion 11, a bent portion 16B connected to the rising portion 16A, and a fixed portion 16C connected to the bent portion 16B. The rising portion 16A extends in the opposite direction to the first base portion 14 and the second base portion 15. The bent portion 16B extends in a direction overlapping with the connecting portion 11 in a plan view. The fixed portion 16C is connected to the tip of the bent portion 16B. The tip side of the bent portion 16B is inclined in a direction away from the connecting portion 11 toward the fixed portion 16C. The fixed portion 16C has the function of fixing the conductor. The conductor is fixed to the surface of the fixed portion 16C opposite to the conductor side formed on the glass plate (the surface opposite to the connecting portion 11 side).

[0017] In this embodiment, the fixing portion 16C is configured as a crimping portion. The crimping portion has a U-shape having a pair of opposing wall portions and a connecting portion that connects the ends of the pair of wall portions. That is, the fixing portion 16C is bent in the direction opposite to the conductor side formed on the glass plate (in the direction away from the connecting portion 11), thereby crimping the conductor. The fixing portion 16C may be configured as a soldered portion or a welded portion instead of a crimping portion. Furthermore, the fixing portion 16C and a portion of the conductor fixed to the fixing portion 16C may be covered with a protective member made of an insulator. The insulator is formed of an insulating material, for example, a resin. The resin is preferably a material with excellent flexibility. The resin is not particularly limited, but examples thereof include polyvinyl chloride, fluororesin, natural rubber, synthetic rubber, polyethylene terephthalate, polyolefin, and polyimide. It is preferable that the fixing portion 16C and a portion of the conductor fixed to the fixing portion 16C are covered with a protective member made of an insulator, because even if an external force is applied to the metal terminal 10 or the conductor, causing the metal terminal 10 to deform and come into direct contact with the vehicle window glass or a metal vehicle body, the vehicle window glass will not be damaged and a short circuit will not occur with the vehicle body.

[0018] FIG. 3 is a three-view diagram of the metal terminal 10, where (A) is a plan view, (B) is a front view, and (C) is a side view.

[0019] As shown in Fig. 3(A), the connecting portion 11 has a rectangular shape in a plan view. The connecting portion 11 has a first side 11A, a second side 11B opposite the first side 11A, and a third side 11C and a fourth side 11D adjacent to and opposite the first side 11A and the second side 11B. In the embodiment of Fig. 3(A), the first side 11A and the second side 11B correspond to the short sides of the connecting portion 11, and the third side 11C and the fourth side 11D correspond to the long sides of the connecting portion 11.

[0020] As shown in Fig. 3, a first leg 12 is connected to a first side 11A of the connecting portion 11. A first base 14 is connected to the first leg 12. A second leg 13 is connected to a second side 11B of the connecting portion 11. A second base 15 is connected to the second leg 13.

[0021] 3(A) and 3(C), the first pedestal portion 14 and the second pedestal portion 15 protrude from an imaginary extension line VL of the third side 11C in the direction opposite to the fourth side 11D (in the direction of the arrow). In this embodiment, the imaginary extension line VL of the third side 11C substantially coincides with a center line CL1 that connects the centers of the first pedestal portion 14 and the second pedestal portion 15. The distance between the imaginary extension line VL and the center line CL1 is preferably within 2.0 mm.

[0022] The conductor connection portion 16 has a rising portion 16A that connects to the third side 11C of the connecting portion 11. The rising portion 16A extends in the opposite direction to the conductors connected to the first pedestal portion 14 and the second pedestal portion 15. The rising portion 16A is approximately perpendicular to the connecting portion 11. The rising portion 16A connected to the third side 11C is also positioned at a position that approximately coincides with the center line CL1 that connects the centers of the first pedestal portion 14 and the second pedestal portion 15. The center line CL2 of the connecting portion 11 and the center line CL3 of the rising portion 16A approximately coincide with each other. It is preferable that the distance between the center lines CL2 and CL3 be within 2.0 mm.

[0023] Conductor connection portion 16 is connected to rising portion 16A and has bent portion 16B extending toward fourth side 11D. Bent portion 16B is substantially perpendicular to rising portion 16A and overlaps coupling portion 11 in plan view.

[0024] The conductor connection portion 16 includes a fixed portion 16C connected to the bent portion 16B. The fixed portion 16C is connected to the tip side of the bent portion 16B. In the embodiment, the fixed portion 16C is provided at a position beyond the fourth side 11D and at a position that does not overlap with the coupling portion 11 in a plan view.

[0025] The distance H1 from the center of the plate thickness of the first pedestal portion 14 and the second pedestal portion 15 to the center of the plate thickness of the connecting portion 11 is preferably 0.5 mm or more and 6.0 mm or less. The distance H2 from the center of the plate thickness of the connecting portion 11 to the fixing portion 16C is preferably 0.5 mm or more and 5.0 mm or less. In other words, the distance H1 from the center of the plate thickness of the first pedestal portion 14 and the second pedestal portion 15 to the center of the plate thickness of the connecting portion 11 and the distance H2 from the center of the plate thickness of the connecting portion 11 to the fixing portion 16C are the same, or H1 is greater than H2.

[0026] The metal terminal 10 of the embodiment contains at least one selected from the group consisting of copper, brass, iron, chromium, and alloys containing copper, brass, iron, and chromium. The surface of the metal terminal 10 may be subjected to a surface treatment (such as tin plating) as necessary. The thickness of the metal terminal 10 is preferably 0.4 mm or more and 0.8 mm or less. The metal terminal 10 is obtained by stamping (pressing) and bending (bending) a metal plate.

[0027] (Vehicle window glass with metal terminals) The vehicle window glass with a metal terminal will be described with reference to the drawings, in which Fig. 4 is a perspective view of the vehicle window glass with a metal terminal, and Fig. 5 is a side view of the vehicle window glass with a metal terminal.

[0028] As shown in Figures 4 and 5, the vehicle window glass 100 with a metal terminal comprises a glass plate 30, a conductor 40 arranged on at least one main surface of the glass plate 30, and a metal terminal 10 electrically connected to the conductor 40 via solder 50.

[0029] The glass plate 30 may be made of, for example, soda-lime glass, borosilicate glass, alkali-free glass, or quartz glass, without any particular limitations. Among these, soda-lime glass is particularly preferred. The glass plate 30 may be either untempered glass or tempered glass. Tempered glass may be either physically tempered glass or chemically tempered glass. Untempered glass is made by forming molten glass into a plate shape and slowly cooling it. Tempered glass is made by forming a compressive stress layer on the surface of untempered glass. Tempered glass may be either physically tempered glass (e.g., air-cooled tempered glass) or chemically tempered glass. In the case of physically tempered glass, the glass surface may be strengthened by rapidly cooling a uniformly heated glass plate from a temperature near its softening point, thereby generating compressive stress on the glass surface due to the temperature difference between the glass surface and the glass interior. In the case of chemically tempered glass, the glass surface may be strengthened by generating compressive stress on the glass surface using an ion exchange method or the like. Furthermore, the glass plate 30 is preferably transparent, but may also be colored to the extent that transparency is not impaired. The thickness of the glass plate 30 is not particularly limited, but is preferably 0.5 mm or more and 5.0 mm or less.

[0030] The conductor 40 is, for example, a conductive silver paste (electrical resistivity is 0.5 to 9.0 × 10 -8 The conductor 40 is formed by printing or applying a material having a resistivity of Ω·m onto the main surface of the glass plate 30 and then firing the material. The thickness of the conductor 40 is preferably 3 μm or more and 15 μm or less, and more preferably 3 μm or more and 10 μm or less. The conductor 40 may form a bus bar.

[0031] The solder 50 may be lead-free or leaded solder. The solder 50 is preferably lead-free solder that contains almost no lead. The lead-free solder is not particularly limited, but is preferably a solder containing Sn (tin) and Ag (silver), such as Sn-Ag solder, Sn-Ag-In solder, Sn-Ag-Al-Zn solder, Sn-Al-In-Ag-Cu-Zn solder, or Sn-Ag-Cu solder. In this case, the Sn (tin) content is preferably 95% by mass or more.

[0032] The metal terminal 10 is placed on a conductor 40 provided on the glass plate 30. The first pedestal portion 14 and the second pedestal portion 15 of the metal terminal 10 are electrically connected to the conductor 40 via solder 50. The first leg portion 12 and the second leg portion 13 separate the connecting portion 11 from the conductor 40. In the embodiment, the sides of the first pedestal portion 14 and the second pedestal portion 15 that protrude beyond the third side 11C of the connecting portion 11 face the direction in which the conductor 60 extends. Therefore, the rising portion 16A and the third side 11C of the conductor connection portion 16 face the direction in which the conductor 60 extends.

[0033] The conductor 60 is fixed to the fixing portion 16C of the conductor connection portion 16 by crimping. The conductor 60 is composed of a core wire and an insulator that covers the core wire. The core wire at one end of the conductor 60 protrudes from the insulator and is crimped by the fixing portion 16C. As a result, the conductor 60 and the conductor 40 are electrically connected via the metal terminal 10 and the solder 50.

[0034] The core wire is made of, for example, a metal. The metal is not particularly limited, but examples thereof include gold, silver, nickel, copper, aluminum, tin, cobalt, and alloys containing at least one of these elements. The core wire may be a single linear conductive material or a bundle of multiple linear conductive materials. The diameter of the core wire is approximately 2 mm to 8 mm, but is not limited to this. The insulator is made of an insulating material, for example, a resin. The resin is preferably a material with excellent flexibility. The resin is not particularly limited, but examples thereof include polyethylene terephthalate, polypropylene, polyethylene, and polyimide.

[0035] The metal terminal 10 is preferably disposed on the interior side of the vehicle when the vehicle window glass 100 with a metal terminal is attached to the vehicle.

[0036] As shown in Figure 5, in the vehicle window glass 100 with metal terminal, the wire connection portion 16 and the connecting portion 11 form a U-shape that opens toward the fourth side 11D of the connecting portion 11 when viewed from the side of the first side 11A or the second side 11B.

[0037] When an external force F is applied to the conductor 60 in a direction perpendicular to the glass plate 30, the external force is also applied to the conductor connection portion 16. On the other hand, because the metal terminal 10 has the above-described configuration, when an external force is applied to the conductor connection portion 16, the external force F deforms the conductor connection portion 16. The deformation of the conductor connection portion 16 prevents the external force F from being transmitted to the first pedestal portion 14 and the second pedestal portion 15. Even if the external force F is transmitted to the first pedestal portion 14 and the second pedestal portion 15, the deformation of the conductor connection portion 16 ensures that the force is applied uniformly to the first pedestal portion 14 and the second pedestal portion 15. As a result, the vehicle window glass 100 with a metal terminal can prevent cracks from occurring in the glass plate 30 due to the external force applied to the metal terminal 10.

[0038] 5, the conducting wire 60 is fixed to the fixing portion 16C in a direction extending from the fixing portion 16C toward the third side 11C of the connecting portion 11. The direction is not limited to this, and the conducting wire 60 may be fixed to the fixing portion 16C in a direction extending from the fixing portion 16C toward the fourth side 11D of the connecting portion 11.

[0039] Another embodiment of a vehicle window glass with a metal terminal will be described with reference to the drawings. As shown in FIG. 6, the vehicle window glass with a metal terminal 200 is composed of laminated glass 35 having an interlayer 34 that bonds a first glass sheet 32 ​​and a second glass sheet 33. The first glass sheet 32 ​​constitutes a glass sheet, and the second glass sheet 33 constitutes an additional glass sheet. The vehicle window glass with a metal terminal 200 is applied to a vehicle windshield, for example. When the vehicle window glass with a metal terminal 200 is assembled to a vehicle body, the first glass sheet 32 ​​is arranged on the exterior side of the vehicle, and the second glass sheet 33 is arranged on the interior side of the vehicle.

[0040] The first glass plate 32 and the second glass plate 33 can be the same glass plate as the glass plate 30. Therefore, the first glass plate 32 and the second glass plate 33 may be either untempered glass or tempered glass. The thicknesses of the first glass plate 32 and the second glass plate 33 may be the same or different.

[0041] For example, the thickness of the first glass plate 32 is preferably 1.1 mm or more and 3.0 mm or less. When the thickness of the first glass plate 32 is 1.1 mm or more, sufficient strength is obtained, such as resistance to flying stones, and when the thickness is 3.0 mm or less, the mass of the laminated glass 35 is not too large, which is preferable in terms of vehicle fuel efficiency. The thickness of the first glass plate 32 is more preferably 1.5 mm or more and 2.8 mm or less, and even more preferably 1.8 mm or more and 2.6 mm or less. The thickness of the second glass plate 33 is preferably 0.5 mm or more and 2.3 mm or less. When the thickness of the second glass plate 33 is 0.5 mm or more, handling is good, and when it is 2.3 mm or less, the mass is not too large, which is preferable.

[0042] In addition, either or both of the first glass plate 32 and the second glass plate 33 may be wedge-shaped so that the thickness increases from the lower edge side (engine hood side) to the upper edge side (roof side) when the laminated glass 35 is assembled to the vehicle body.

[0043] The first glass sheet 32 ​​and the second glass sheet 33 are formed into a sheet shape by, for example, a float process, and then bent at high temperatures by gravity forming or press forming. The laminated glass 35 may have a complex curved shape, i.e., curved in both the longitudinal and lateral directions. Alternatively, the laminated glass 35 may have a single curved shape, i.e., curved only in the longitudinal direction, or curved only in the lateral direction. When the laminated glass 35 is curved, it is preferably curved so as to be convex toward the exterior of the vehicle. When the laminated glass 35 is curved, the radius of curvature is preferably 1,000 mm or more and 100,000 mm or less. The radii of curvature of the first glass sheet 32 ​​and the second glass sheet 33 may be the same or different. When the radii of curvature of the first glass sheet 32 ​​and the second glass sheet 33 are different, the radius of curvature of the first glass sheet 32 ​​is larger than the radius of curvature of the second glass sheet 33.

[0044] The interlayer film 34 bonds the first glass sheet 32 ​​and the second glass sheet 33 together. The interlayer film 34 may be made of polyvinyl butyral (PVB), or, when water resistance is particularly required, ethylene vinyl acetate copolymer (EVA) is preferably used. Furthermore, acrylic photopolymerizable prepolymers, acrylic catalyst-polymerized prepolymers, acrylic ester-vinyl acetate photopolymerizable prepolymers, or polyvinyl chloride may also be used. The interlayer film 34 may have either a single-layer structure or a multi-layer structure. The thickness of the interlayer film 34 is preferably 0.5 mm or more and 3.0 mm or less. A thickness of 0.5 mm or more ensures the necessary penetration resistance for a windshield. Furthermore, a thickness of 3 mm or less of the interlayer film 34 is lightweight and easy to handle.

[0045] A dark, opaque shielding layer (not shown), such as a black one, may be formed in a band shape around the entire periphery of the laminated glass 35. This shielding layer may be provided on both the first glass sheet 32 ​​and the second glass sheet 33, or on only one of them. The shielding layer has the function of protecting the urethane sealant that adheres and holds the laminated glass 35 to the vehicle body from deterioration due to ultraviolet rays. The shielding layer is formed by applying a ceramic paste to the surface of the first glass sheet 32 ​​and / or the second glass sheet 33, followed by firing. The thickness of the shielding layer is preferably 3 μm or more and 15 μm or less. The width of the shielding layer is not particularly limited, but is preferably 20 mm or more and 300 mm or less.

[0046] In the vehicle window glass 200 with a metal terminal, the second glass sheet 33 has an arc-shaped cutout 36 formed on the periphery thereof so as to penetrate the second glass sheet 33 in the thickness direction. A conductor 40 is formed on the surface of the first glass sheet 32 ​​facing the interior of the vehicle, which is exposed by the cutout 36. If a shielding layer is formed, the conductor 40 is formed on the shielding layer.

[0047] The first seat portion 14 and the second seat portion 15 of the metal terminal 10 are electrically connected to the conductor 40 arranged on the first glass sheet 32 ​​via the solder 50. The conductor 60 and the conductor 40 are electrically connected via the metal terminal 10 and the solder 50. The metal terminal 10 is attached to the first glass sheet 32 ​​with the rising portion 16A and the third side 11C of the conductor connection portion 16 facing the peripheral edge of the laminated glass 35. The conductor 40 and the solder 50 in the vehicle window glass 200 with a metal terminal may be similar to those in the vehicle window glass 100 with a metal terminal. The sum of the distance H1 from the center of the thickness of the first seat portion 14 and the second seat portion 15 to the center of the thickness of the connecting portion 11 and the distance H2 from the center of the thickness of the connecting portion 11 to the fixing portion 16C is greater than the sum of the thickness of the second glass sheet 33 and the thickness of the interlayer film 34.

[0048] The vehicle window glass with metal terminal 200 also uses a metal terminal 10 having the same configuration as the vehicle window glass with metal terminal 100, so even if an external force is applied to the conductive wire 60, cracks are prevented from occurring in the first glass plate 32.

[0049] Although not shown in the drawings, bus bars can be formed from the conductors 40 in the vehicle window glass with metal terminal 100 and the vehicle window glass with metal terminal 200. A plurality of bus bars are formed, for example, along the peripheral edge of the glass plate 30. A metal terminal 10 is electrically connected to each bus bar, and the bus bars are connected to the anode and cathode of a power source. For example, a heating wire is arranged to connect between each bus bar.

[0050] The heating wires are, for example, fine tungsten wires. In this case, the multiple wires may be spaced apart from one another, or may be in the form of a mesh with the wires crossed. Alternatively, a transparent conductive film may be formed instead of the heating wires. Examples of the transparent conductive film include a metal film such as an Ag film, a metal oxide film such as an ITO (indium tin oxide) film, or a resin film containing conductive particles. The transparent conductive film may also be a laminate of multiple types of films.

[0051] Fig. 7 is a cross-sectional view of a molding 70 attached to the vehicle window glass with metal terminal 200 shown in Fig. 6. The conductor 40 and the solder 50 are omitted from Fig. 7. As shown in Fig. 7, a spacer 72 is attached to part of the cutout 36 at the periphery of the lower side of the laminated glass 35. The spacer 72 is made of a flat resin block having a thickness equal to the combined thickness of the second glass sheet 33 and the interlayer film 34.

[0052] The molding 70 includes a flat portion 70A and a hook portion 70B. The flat portion 70A is positioned opposite the spacer 72, and the hook portion 70B is positioned beyond the peripheral edge of the lower side of the laminated glass 35. The flat portion 70A of the molding 70 and the spacer 72 are adhered with double-sided adhesive tape 74.

[0053] For example, a dam member 76 is attached to the interior surface of the second glass sheet 33. The height of the dam member 76 is set to be higher than the height of the metal terminal 10. Note that the height referred to here is the height (length) of the second glass sheet 33 from the interior surface of the vehicle.

[0054] The vehicle window glass 200 with a metal terminal is provided with a sealant 78 so as to cover the notch 36, the metal terminal 10, and a part of the lead wire 60. The sealant 78 is, for example, a silicone resin.

[0055] It is preferable that the height of the metal terminal 10 up to the conductor connection portion 16 is greater than the thickness of the first glass plate 32. When the metal terminal 10 has such a height, the conductor 60 connected to the metal terminal 10 is not bent significantly within the sealing material 78, and the conductor 60 can have a longer life.

[0056] The present invention has been described above in terms of the preferred embodiment, but the present invention is not limited to the above examples, and various improvements and modifications can be made without departing from the spirit and scope of the present invention. The vehicle window glass with a metal terminal can be applied to, for example, a windshield, a rear window, a side door window, and a quarter window. [Explanation of symbols]
