  The laminated glass region 34 is a region on the entire surface of the laminated glass 12 excluding the exposed region 13 composed of the molding mounting region 32 and the electrode arrangement region 36. In the embodiment, the exposed region 13 has a semi-elliptical shape as shown in FIG. 2, but is not limited thereto, and may be a semi-circular shape or a rectangular shape.

[Spacer 38]
As shown in FIG. 3, in the molding mounting region 32, a flat plate-like resin having a thickness obtained by adding the thickness of the glass plate 18 and the thickness of the intermediate film 20 between the glass plate 16 and the flat plate portion 4 </ b> A of the molding 4. A spacer 38 made of metal is arranged. The spacer 38 acts as if the glass plate 18 and the intermediate film 20 removed in the exposed region 13 exist. Therefore, the distance from the glass plate 16 to the molding 4 in the exposed region 13 is substantially equal to the distance from the glass plate 16 to the molding 4 other than the exposed region 13. Here, when the molding 4 is provided in addition to the exposed region 13, the molding 4 is provided on the glass plate 18. That is, since the molding 4 is provided in the exposed region 13 as if the molding 4 was provided on the glass plate 18, the molding 4 was stably provided on the laminated glass 12.

Accordingly, the spacer 38 has a surface area of the spacer 38 that is larger than that of the smooth surface, and has an improved adhesive force due to the anchor effect of the minute protrusions provided on the non-smooth surface.

  In the case of manufacturing the spacer 38 by injection molding, in order to facilitate the manufacture of the spacer 38, the molding surface of the mold is roughened by a blasting device such as a sand blasting device, and the roughened molding surface of the spacer 38 is formed. Transfer to the surface. Thereby, the spacer 38 whose surface is a non-smooth surface can be easily manufactured, and is suitable for mass productivity.

[Terminal (power supply terminal) 42]
Conductive wires 40 are connected to the electrodes 26, 28, and 30 shown in FIG. The terminal 42 is joined to the electrodes 26, 28, and 30 by soldering. Then, the electrode placement region 36 shown in FIG. 3 is filled with the sealing material 14 as shown in FIG. As a result, the electrodes 26, 28, 30, the terminals 42 joined to the electrodes 26, 28, 30, and the conductors 40 whose ends are joined to the terminals 42 are brought together by the sealing material 14 in the electrode arrangement region 36. Buried.

  Here, the terminal 42 will be described in detail with reference to the drawings. 5 to 10 are diagrams for simply explaining the structure of the terminal 42. FIG. 5 is a perspective view of the terminal 42 as viewed from obliquely behind (the direction in which the conductor 40 is inserted). FIG. 6 is a side view seen from the direction A in FIG. FIG. 7 is a top view seen from the direction B of FIG. FIG. 8 is a front view seen from the direction C of FIG. As shown in FIG. 8, the terminal 42 includes a fixing portion 81 for electrically and physically connecting the conducting wire 40. FIG. 9 is a front view showing a mechanism when the fixing portion 81 connects the conductive wire 40. FIG. 10 is a perspective view of the state of FIG. 9 when viewed from obliquely above the terminal 42.

  As shown in FIG. 5, the terminal 42 is connected to the first grounding portion 51, the second grounding portion 52, and the first grounding portion 51 that are bonded to the vehicle inner surface of the glass plate on the vehicle outer surface side. A direction extending away from the glass plate on the outer surface side and connected to the first leg portion 53 and the second grounding portion 52 longer than the thickness of the glass plate on the inner surface side of the vehicle and away from the glass plate on the outer surface side of the vehicle A second leg 54 that is longer than the thickness of the glass plate on the inner surface of the vehicle, an upper surface 55 that connects the first leg 53 and the second leg 54, and is connected to the upper surface 55. And a fixing portion 81 for fixing a part of the conducting wire so as to be electrically connected.

  As shown in FIG. 5, the terminal 42 includes a fixing portion 81 on the side (C side) opposite to the direction (D side) in which the conducting wire 40 is inserted. Then, the terminal 42 is electrically and physically connected to a part of the tip region into which the conducting wire 40 is inserted, using the fixing portion 81, with the conducting wire 40 inserted from the D side. As shown in FIGS. 9 and 10, the fixing portion 81 has a mechanism that bends the tip 82 inward and crimps the conducting wire 40 between the inner surface 83 and the tip 82 of the fixing portion 81. In FIGS. 9 and 10, the conductive wire 40 is not shown for easy understanding of the crimping mechanism of the fixing portion 81. For this reason, the tip 82 of the fixing portion 81 and the inner surface 83 are in contact with each other. However, since the lead wire 40 is actually crimped, the tip 82 of the fixing portion 81 and the inner surface 83 are not necessarily in contact with each other. Needless to say.

  Here, the lengths of the first leg portion 53 and the second leg portion 54 are such that at least the glass plate 18 on the vehicle inner surface side when the terminal 42 is bonded to the vehicle inner surface side surface of the glass plate 16 on the vehicle outer surface side. It should be longer than the thickness. The length of the first leg portion 53 and the second leg portion 54 is such that the thickness of the intermediate film 20 existing between the glass plate 16 on the vehicle outer surface side and the glass plate 18 on the vehicle inner surface side and the glass inner surface side on the vehicle inner surface side. Longer than the total thickness of 18 is preferred. By having such a length, there is an effect that the conductor 40 connected to the terminal 42 can be contributed to the extension of the life of the conductor 40 without being greatly bent in the sealing material 14.

  The material of the terminal 42 is obtained by punching (pressing) or bending (bending) a metal (iron, copper, copper alloy, etc.) base material. The surface of the terminal 42 is subjected to surface processing (such as tin plating) as necessary.

[Weir member 44]
As shown in FIG. 3, a dam member 44 surrounding the electrode arrangement region 36 is attached to the laminated glass region 34 as shown in FIG. The height of the weir member 44 is set higher than the height of each terminal 42 connected to the electrodes 26, 28, and 30 as shown in FIG. In addition, the height said here is the height (length) from the vehicle inner surface 16A of the glass plate 16.

  By providing such a weir member 44, the filling amount of the sealing material 14 can be increased as compared with the filling amount when there is no weir member 44.

[Features of Windshield Glass 10]
(First feature)
As shown in FIGS. 3 and 4, the end portion 40 </ b> A of the conducting wire 40 is joined to the electrodes 26, 28, and 30 via the terminal 42 in the electrode arrangement region 36 of the exposed region 13. And the fixing | fixed part 81 of the terminal 42 and the edge part 40A of the conducting wire 40 is arrange | positioned in the position spaced apart outward from the vehicle inner surface 18B of the glass plate 18 with respect to the vehicle inner surface 16A of the glass plate 16. The electrode placement region 36 is filled with the sealing material 14, and the electrodes 26, 28, 30, the terminal 42, and the fixing portion 81 between the terminal 42 and the conductive wire 40 are embedded with the sealing material 14.

  That is, in the windshield glass 10 of the embodiment, the end portion 40A of the conducting wire 40 is connected to the electrodes 26, 28, via the terminal 42 protruding outward from the vehicle inner surface 16 A of the glass plate 16 to the vehicle inner surface 18 B of the glass plate 18. 30, even if the windshield glass 10 has a shape in which the molding 4 protrudes on the inner surface side of the laminated glass 12, the wiring angle of the conductive wire 40 inside the sealing material 14 is set to the laminated glass 12. The surface can be made parallel to the surface (for example, the vehicle inner surface 16A of the glass plate 16).

  Thereby, according to the windshield glass 10, peeling of the sealing material 14 filled in the exposed region 13 can be prevented without expanding the exposed region 13, that is, while ensuring the strength of the laminated glass 12.

  Further, according to the windshield glass 10, a position where the fixing portion 81 between the terminal 42 and the end portion 40 </ b> A of the conducting wire 40 is spaced outward from the vehicle inner surface 18 </ b> B of the glass plate 18 with respect to the vehicle inner surface 16 </ b> A of the glass plate 16. Therefore, the thickness of the sealing material 14 filled in the electrode arrangement region 36 is thicker than the windshield glass of Patent Document 1. By increasing the thickness of the sealing material 14, the leakage prevention effect is also improved.

(Second feature)
At least a part of the fixing portion 81 indicated by the broken line in FIG. 3 is positioned in the laminated glass region 34 in a plan view of the laminated glass 12 as viewed from the direction of the arrow A.

  Thereby, in the exposed area | region 13, since the fixing | fixed part 81 can be kept as far as possible from the peripheral part 12A of the laminated glass 12, the wiring angle of the conducting wire 40 in the inside of the sealing material 14 is made into the surface (for example, glass plate) of the laminated glass 12 The vehicle inner surface 16A) can be made more parallel. Therefore, the peeling prevention function of the sealing material 14 is enhanced. Note that it is preferable to place the entire fixing portion 81 in the laminated glass region 34 because it can be made more parallel.

(Third feature)
As shown in FIGS. 2 and 5, the terminal 42 is formed in a tunnel-like gate shape having a first leg portion 53 and a second leg portion 54, and the first leg portion 53 and the second leg portion are formed. The first grounding portion 51 and the second grounding portion 52 are joined to the electrodes 26, 28, and 30. Then, the end 40A of the conducting wire 40 is passed through the gate-shaped terminal 42 and joined to the terminal 42 by caulking at a fixing portion 81 provided at the upper end of the terminal 42.

  By making the terminal 42 into a tunnel-like gate shape, the fixing portion 81 can be arranged at the separated position with a simple structure. Further, the end portion 40A of the conducting wire 40 can be easily joined to the terminal 42 by joining the end portion 40A of the conducting wire 40 to the terminal 42 by caulking.

<Fourth feature>
As shown in FIG. 2, an arc-shaped weir member 44 surrounding the electrode arrangement region 36 is attached to the laminated glass region 34.

  Since the filling amount of the sealing material 14 can be increased by the height of the weir member 44, the water tightness of the electrode arrangement region 36 can be further improved, and the leakage preventing effect is further improved.

  In addition, in embodiment, although the joining form of exothermic filaments 22 and 24 and the conducting wire 40 was demonstrated, even if it is a joining form of electroconductive patterns other than the exothermic filaments 22 and 24 and the conducting wire 40, it is of this invention. A joining form can be applied.
