Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vehicle window having a heating wire, a conductive wire such as an antenna, and the like on the indoor side.

[Conventional technology]

Some rear windows of vehicles have a heating wire, a conductive wire such as an antenna, and the like on the indoor side. A window has been proposed in which lead wires, connectors, etc. connected to these conductive wires are embedded in a frame material formed by injection molding at the peripheral edge of the window plate (Japanese Patent Laid-Open No. 63-22725, Japanese Utility Model Laid-Open No. 63-25725). Sho 63-15215).

However, in such a window, the lead wire may be torn off by the pressure of the injected resin, so that the reliability is inferior, and the lead wire vibrates due to the resin flow and disturbs the resin flow. There was a problem that the surface was not uniform and the appearance was impaired.

Also known is one in which a socket connected to the terminal of the conductive wire is adhered to the interior side of the window plate independently of the frame member, but there is a problem in that the socket is likely to fall off due to vibration due to running of the vehicle.

[Problems to be solved by the device]

An object of the present invention is to provide a vehicle window which is free from disconnection, resin disorder, etc., can firmly fix a socket to a window plate, has high reliability, and has an excellent appearance in order to solve the above problems. Is.

[Means for Solving the Problems]

 The present invention is the following vehicle window.

(1) A window plate having a conductive wire inside the room,
A frame material fixed to the peripheral portion of the window plate,
A socket having a contact point connected to the terminal of the conductive wire and independently mounted from the frame member on the indoor side of the window plate, and an engaging portion for fixing the socket to the window plate, and by injection molding A vehicle window including an injection-molded portion fixed to a window plate via an adhesive layer.

(2) The vehicle window according to (1) above, wherein the socket is fixed to the window plate at the base through a cushioning material.

[Action]

In the vehicle window of the present invention, when the frame material is formed on the peripheral edge of the window plate by injection molding, the socket is fixed to the back surface of the window plate, and the portion where the adhesive layer is formed is injection-molded and injection-molded. A molded part is formed and fixed to the window plate, and the socket is attached to the indoor side of the window plate.

The injection-molded portion is firmly fixed to the window plate by the resin pressure during injection molding, and therefore does not fall off due to vibration.
Also, during injection molding, the lead wire is not exposed, so there is no disconnection or disturbance of the resin flow, and the reliability is high.
Moreover, a window with an excellent appearance can be obtained.

By interposing a cushioning material at the base of the socket, interference between the socket and the bus bar can be avoided.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a window (rear window) of the embodiment, FIG. 2 is a sectional view taken along the line AA, FIG. 3 is a partial perspective view, and FIG. 4 is a sectional view taken along the line BB. The figure is a cross-sectional view showing a molded state.

In the figure, 1 is a window, and 2 is a window plate.
The frame member 3 is formed on the peripheral edge of the by injection molding. A heating wire 4 and an antenna 5 are provided on the indoor side of the window plate 2.
Conductive wires such as are formed and are connected to the connector 7 by the bus bar 6. The heating wire 4, the antenna 5, the bus bar 6 and the like are formed by baking a material having a predetermined electric resistance, for example, conductive wire ink.

The connector 7 is formed by fixing the socket 8 to the interior side of the window plate 2 via the adhesive layer 10 by the injection molding section 9. The socket 8 has a recess at the base 8a that avoids the bus bar 6, and is fixed to the window plate 2 with an adhesive layer 10. Further, inside the socket 8, a contact 12 made of an elastic metal plate that elastically contacts the terminal 11 of the bus bar 6 is attached so that the plug can be inserted.

The injection molding portion 9 has an engaging portion 9a on the entire circumference of the socket 8 so as to fix the socket 8 to the window plate 2.
The base portion 9b is fixed to the window plate 2 by the adhesive layer 10. The injection molding part 9 is integrated with the frame material 3 by the connecting part 13, and these are simultaneously formed by injection molding. The frame member 3 is also fixed to the window plate 2 by the adhesive layer 10. Reference numeral 14 is an opaque print layer formed on the inner peripheral edge of the window plate 2.

A molding die 20 has a cavity 23 for forming the frame member 3 between a lower die 21 and an upper die 22. A socket holding mold 24 is pressed against the upper mold 22 by a compression spring 25 toward the window plate 2 side. The socket holding mold 24 has a socket receiving hole 26, and a cavity 27 for forming an injection molding portion formed between the socket holding die 24 and the window plate 2 is a connecting portion.
It communicates with the cavity 23 for forming the frame material through the cavity 28 for forming 13.

The window 1 is a mold for forming the window plate 2
Set so that the socket 8 is inserted into the cavity 23, attach the socket 8 to the socket receiving hole 26 of the socket holding mold 24, clamp the mold, and inject the resin into the cavities 23, 27, 28 for injection molding, 3, the connecting portion 13 and the injection molding portion 9 are integrally formed. The frame material 3 and the injection molding portion 9 are fixed to the window plate 2 by the adhesive layer 10, but the connecting portion 13 may be cut off after molding.

The window 1 thus manufactured has an opaque printed layer.
Install the dam rubber along the line 14 and fill the periphery with adhesive to attach it to the opening of the body panel for use. Then, a plug is inserted into the socket 8 to energize.

At this time, the injection molding portion 9 is firmly fixed to the window plate 2 by the resin pressure at the time of injection molding, so that the injection molding portion 9 does not fall off due to vibration. Further, since the lead wire is not exposed during injection molding, disconnection, disturbance of resin flow, etc. do not occur, and the window 1 having high reliability and excellent appearance can be obtained.

FIG. 6 is a sectional view of another embodiment, in which the socket 8 is a base portion.
It is fixed to the window plate 2 via a cushioning material 29 on 8a. By interposing the cushioning material at the base of the socket in this way, the interference between the socket and the bus bar can be avoided.

In the above description, the socket 8 and the injection molding part 9
Structures such as are not limited to those shown in the drawings, and can be changed.

[Effect of device]

According to the present invention, the socket is independent of the frame member and fixed to the window plate by the injection molding section, so that the socket can be firmly fixed to the window plate without disconnection or disturbance of resin flow, and the reliability is high. Moreover, a vehicle window having an excellent appearance can be obtained.
