Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector, and more particularly to a T-shaped connector for connecting to a busbar on a glass window, such as the rear window of a car.

A heated car window has on its surface a row of electrically resistive heating elements formed by two electrically conductive frits conventionally baked into the glass surface near each side of the rear window. It usually extends between the busbars. Resistive heating elements are commonly formed from similar conductive frits.

Modern cars have narrow rear corner pillars, so there is no space to hide a regular T-shaped connection piece. Such a common connector is the one described in British Patent No. 1163224, which states:
A T-shaped connector is shown in which the T crosspiece is formed as follows. That is, with a central bridge remote from the generatrix, both ends of this crosspiece are formed as one bridge, which remains to be soldered to the generatrix. The stringers of this T-shaped connector project between 25 mm and 50 mm onto one side of said bridge, and a lead wire, for example a lead wire terminating in a spade-shaped connector, approaches said connector from one side and adjoins the end of the stringer. In many automobiles, the rear pillars are large enough to accommodate the aforementioned conventional connectors invisibly. However, if the pillars are narrow this becomes difficult or impossible, especially at T
This is the case where the length of the longitudinal member of the shaped connector corresponds to the width of the rear pillar.

The object of the invention is to obtain an improved connector of this type which can be connected to a bus bar on a glass window in locations where there is not enough corner space to arrange the connector in a conventional manner.

The present invention is for connecting to a bus bar on a glass window, having a cross member bent to form a central bridge connecting the two parts connected to the bus bar, and an integral longitudinal member forming the connection. In a T-shaped connector, the length member is formed as an L-shaped connecting tab;
The stringers are folded so that when the connector is connected to the busbar and in place, the L-shaped tab is above the bridge and the entire connector is over the busbar.

The connector may be soldered to the busbar while the crosspiece is bent to form a bridge but still mostly flat. Typically, in carrying out the invention, the connector is soldered to the bus bar with the longitudinal member bent in the same direction as the bridge at the connection between the longitudinal member and the cross member.

The L-shaped stringer of the connector may have two side notches that define a fold line for folding the tab over the bridge.

Preferably, the stringers are bent at right angles and the tabs are folded at right angles to the bent portions of the stringers.

The two parts of the crosspiece that are connected to the busbar are preferably enlarged parts that are soldered to the busbar.

In one embodiment of the invention, two
The above-mentioned connector of the present invention is attached to each of the two busbars of a car glass window, which has a row of electric resistances extending to the vicinity of both sides of the window, which has connectors on the busbars for connection with lead wires. Soldered and bent so that each connector's tab is on its busbar.

The invention will now be explained by way of example with reference to the accompanying drawings.

In the figure, a T-shaped connector for connecting to a busbar on a glass window has a cross member 1 and an integral longitudinal member 2 formed as an L-shaped connecting tab. As shown in FIG. 2, said cross member 1 is slightly bent to form a central bridge 3 connecting two ears 4, said ears being soldered in the usual manner. This is for connecting to two busbars.

In this embodiment, in the communication between integral longitudinal members and cross members, the longitudinal members are arranged in the same direction as the bridge, i.e. in the second
In the figure, it is bent upward at a right angle. The L-shaped connecting tab 6 of the stringer 2 has a tongue 7 into which a female connector is inserted and fixed. The folded section 5 of the stringer has two lateral cuts which define a folding line 9 for folding the connecting tab 6 at right angles to the folded section 5 of the stringer and above the bridge.

3 and 4 show a portion of a generatrix consisting of a conventional silver-containing frit 10 baked into the surface of a glass window, designated 11, which is normally used for the rear window of a motor vehicle. It is. The busbars and the heating elements extending between the busbars are typically baked into the inside of the window.

The connector is stamped from a copper plate and dipped in molten tin. This connector is placed in contact with the generatrix with enlargements 12 forming the legs of the ends of the crosspiece, and is soldered to the generatrix at this enlargement. After soldering,
The L-shaped connecting tab 6 is bent at the folding line 9 into the shape shown in FIGS. 3 and 4, and the connecting tab is folded over the bridge of the connector and rests on the busbar 10. The entire connector thus lies within the boundaries of the busbar and above the busbar and can be mated with a female connector having leads that lie above the busbar, thereby
A tidy assembly is obtained which can be placed neatly near the narrow rear corner pillar of a motor vehicle. If the busbar is on the inside surface of the window, the connector and lead wires will be hidden behind the busbar when viewed from the outside.

In another embodiment, the connector is soldered to the bus bar while it is still flat, i.e. before it is bent at the connection between the longitudinal and cross members. After soldering the enlarged part 12 of the cross member 1 to the bus bar, first bend the longitudinal member into the shape shown in FIGS. The entire connector should be placed above the bus bar as shown in FIG.

As indicated by the dotted lines 13 in FIG. 2, the L-shaped connecting tabs may be oriented in the opposite direction to the tabs 6 of the illustrated embodiment. This connecting tab 13, when bent over the bridge 3, also lies within the boundaries of and above the generatrix.

Each connector may have two connecting tabs 6 and 13, in which case it can be connected from either direction depending on the layout of the particular vehicle.
