Abstract

The high voltage transformer 1 is of a type used to provide horizontal line deflection of such as a cathode ray tube. The transformer has a pair of guide channels that receive the plug sections of a U shaped terminal connector 13. The connector has lines for high voltage 124, focus 125 and screen 126 outputs. Within the terminal plug the lines connect with end contact points.

Description

The invention relates generally to a horizontal deflection transformer gate and in particular on a clamp device for output lines a horizontal deflection transformer.

A horizontal deflection transformer is generally in the circuits a display device for providing different voltages implemented by the circuit operation of the display device are required. It will refer to U.S. Patents 5,160,872, 5,287,479 and 4,144,480 related to a deeper understanding of the structure Ren a horizontal deflection transformer and the functions of a high voltage output, a focus output and a screen output of the To have horizontal deflection transformers.  

From US 5 160 872 is a horizontal deflection transformer with one each High voltage (anode) output line, a focus output line and known a screen output line, in which the screen off gear line on the transformer housing is fixed by means of clamps.

In DE 38 00 477 A1 is a high voltage transformer for Fernsehge advised in which a sleeve with molded bracket for each a cable as a high-voltage line and a connection cable as a focus line is provided, the connection ends of the high-voltage line and Focus line with a corresponding connector pin each Terminal are connected once the sleeve is on an extension the insulating material housing is pushed on. The high voltage cable is thus form-fitting.

A conventional way of assembling the high voltage output line of a horizontal deflection transformer is presented below.

The high voltage output line is manually in the appropriate Slot of the high voltage coil inserted before the insulating resin was injected the high voltage from other components of the horizontal Deflection transformer isolated. The horizontal deflection transformer is  finally completed after the focus output line and the Screen output line have been manually inserted into it.

This subject of a horizontal deflection transformer with output lines then typically becomes an assembly area of the printed Circuit card transported by a conveyor system. The operator of this Mounting area then mounts the horizontal deflection transformer to one predetermined location of the printed circuit board. Then the is printed te circuit card with the horizontal deflection transformer and the off passage lines thereupon to a mounting area of the display device typically transported a conveyor system. From the above citations it is obvious that during the transportation process the high voltage, Focus and screen output lines due to some unexpected Factors can be damaged. Such damage can occur in one Malfunction of the printed circuit board result. Also manual insertion the high voltage, focus and video output lines can introduce mistakes. In addition, together Construction of the printed circuit board that the output lines on has its predetermined location in the interior of the display device special concentration of the operator.

It is an object of the invention to address the disadvantages of eliminate conventional solutions.

In order to overcome the disadvantages mentioned above, the present Invention a clamp device ready on which the output lines are. The clip is in a corresponding slot in the Hori zontal deflection transformer at the final assembly stage of the display direction inserted. The horizontal deflection transformer is already with the printed circuit board assembled when the stapler is inserted becomes.  

A clamp device for a high voltage output line, one Focus output line and a screen output line of a horizontal Deflection transformer is provided.

The horizontal deflection transformer has at least one slot Insert the stapler on. The slot has a lower end, on the three terminals are provided. The high voltage output, the focus output and the screen output of the horizontal deflection trans formators are output at three respective terminals.

The stapler is characterized in that there are three slots in the clamp device for inserting the high-voltage output line, the focus output line or the screen output line. Three Terminals are then in contact with the high voltage output line, the focus output line or the screen output line if the Clamping device in the slot of the horizontal deflection transformer is inserted.

In a preferred embodiment, the three terminals are at the lower end of the slot of the horizontal deflection transformer made of elec trisch conductive rubber.

Further exemplary embodiments and preferred embodiments result itself from the accompanying drawings.

Fig. 1 illustrates an exploded view of the clamp device and the corresponding horizontal deflection transformer.

Fig. 2 illustrates the contact relationship between the Klammervor direction, the output lines thereon and the horizontal deflection transformer in a partial sectional view.

As shown in FIG. 1, the horizontal deflection transformer 1 has slots for inserting a clamp device 13 . There are three slots 123 , 122 , 121 in the clip 13 for inserting the high voltage output line 124 , the focus output line 125 and the screen output line 126, respectively.

As shown in Fig. 2, the slot of the horizontal deflection transformer 1 has a lower end at which three terminals 127 , 128 and 129 are provided, and a high voltage output, a focus output and a screen output of the horizontal deflection transformer 1 are at the three Terminals 127 , 128 and 129 output.

When the stapler 13 is inserted into the slots of the horizontal deflection transformer 1 , the three terminals 127 , 128 and 129 are in contact with the high voltage output line 124 , the focus output line 125 and the screen output line 126, respectively.

Via the clamp device 13 of the invention, the manufacturer can first inject an insulating resin and then insert the three output lines into the horizontal deflection transformer 1 by means of the clamp device 13 in a single step. Or the horizontal deflection transformer 1 can alternatively be coupled to the printed circuit card first without the clip device 13 on it. In the last assembly stage of the display device, the clip device 13 is inserted into the corresponding slots of the horizontal deflection transformer 1 , which is already arranged on the printed circuit card is.
