Abstract

A vehicle window glass with a metal terminal includes a glass plate, a conductor disposed on at least one of principal surfaces of the glass plate, and a metal terminal electrically connected to the conductor via solders. The metal terminal includes a connection portion; a first leg portion connected to the connection portion; a first base portion connected to the first leg portion; a second leg portion connected to the connection portion; a second base portion connected to the second leg portion; and a lead wire connection portion connected to the connection portion and including a rising portion and a bent portion connected to the rising portion, and a fixing portion connected to the bent portion and configured to be connected to a lead wire.

First claim

What is claimed is:

1. A vehicle window glass with a metal terminal, comprising:
a glass plate;
a conductor, the conductor disposed on at least one of principal surfaces of the glass plate; and
a metal terminal, the metal terminal electrically connected to the conductor via solders;
wherein the metal terminal comprises:
a connection portion, the connection portion including a first side, a second side, a third side, and a fourth side, the second side opposing the first side, the third side and the fourth side being adjacent to the first side and the second side, and opposite to each other;
a first leg portion, the first leg portion connected to the first side and separating the connection portion from the conductor;
a first base portion, the first base portion connected to the first leg portion, electrically connected to the conductor via a solder, and projecting toward a direction away from the fourth side starting from an imaginary extension line of the third side;
a second leg portion, the second leg portion connected to the second side and separating the connection portion from the conductor;
a second base portion, the second base portion connected to the second leg portion, electrically connected to the conductor via a solder, and projecting toward a direction away from the fourth side starting from an imaginary extension line of the third side; and
a lead wire connection portion, the lead wire connection portion connected to the third side of the connection portion, the lead wire connection portion including a rising portion extending in a direction remote from the conductor, a bent portion connected to the rising portion and extending toward the fourth side, and a fixing portion connected to the bent portion and connected to a lead wire.

2. The vehicle window glass according to claim 1 , wherein the metal terminal contains at least one selected from the group consisting of copper, brass, iron, chromium, and an alloy containing copper, brass, iron and chromium.

3. The vehicle window glass according to claim 1 , wherein the fixing portion comprises a caulking portion.

4. The vehicle window glass according to claim 1 , wherein the lead wire is fixed to a surface of the fixing portion remote from the conductor.

5. The vehicle window glass according to claim 1 , wherein the lead wire is fixed to the fixing portion in a direction extending from the fixing portion beyond the third side of the connection portion made of an insulator.

6. The vehicle window glass according to claim 1 , wherein the glass plate comprises tempered glass.

7. The vehicle window glass according to claim 1 , wherein the glass plate comprises non-tempered glass.

8. The vehicle window glass according to claim 1 , wherein the solders comprise leaded solders.

9. The vehicle window glass according to claim 1 , wherein the solders comprise lead-free solders.

10. The vehicle window glass according to claim 9 , wherein each of the solders contains at least 95 weight % of tin.

11. The vehicle window glass according to claim 1 , wherein the glass plate includes a first glass plate, a second glass plate, and an interlayer boning the first glass plate and the second glass plate.

12. The vehicle window glass according to claim 11 , wherein the second glass plate has a cutout portion formed therein so as to pass therethrough in a thickness direction thereof, and the metal terminal is disposed on a surface of the first glass plate exposed by the cutout portion.

13. The vehicle window glass according to claim 12 , wherein the first glass plate is disposed on an exterior side of a vehicle while the second glass plate is disposed on an interior side of the vehicle.

14. The vehicle window glass according to claim 11 , wherein the first glass plate is disposed on an exterior side of a vehicle while the second glass plate is disposed on an interior side of the vehicle.
