Abstract
A sleeve (100) which is not yet threaded is installed in a liner (111) of a deflecting yoke. A slide pin (115) is inserted into the sleeve to the sufficient extent to bring the head part of the pin into contact with the funnel of a cathode-ray tube in which the yoke is installed. After adjustment, a wedge (116) to extend the wall of the pin in the radial direction is inserted into a hollow part of the pin. Consequently, the pin is fixed in the sleeve and the position of the yoke relative to the tube is fixed.
Description
The present invention relates to the deflecting coil of cathode ray tube, more particularly, relate to and a kind of deflecting coil is locked onto locking device on the cathode ray tube after the position mixes up.
The deflecting coil of cathode ray tube is placed on the neck.Be to make its permanent fixation or lock it in to make on the pipe that coil-the cathode ray tube sub-assembly is unlikely to relatively move again after deflecting coil mixes up with respect to the position of cathode ray tube.General total hope prevents to change the position or the geometry of coil in the lock operation process, thereby prevents change level and vertical deflection field.
United States Patent (USP) 4,338,584 have introduced a kind of deflecting coil 1 (as shown in fig. 1), and the separator 12 of coil is made of plastics usually, is used for horizontal deflection coil 13 and frame deflector coil 14 are separated.The rear portion 5 of separator 12 is fixed on the neck 3 with clip 6 ringwise.After adjusting, the front portion 8 of deflecting coil just locks it in place with the pin 9 of being with tooth 10.Pin 9 can be shifted to the flared part 4 of pipe in sleeve pipe 7.Sleeve pipe 7 forms an integral body with separator 12.Tooth 10 meshes with the barbed portion 11 of sleeve pipe 7, prevents that pin 9 from retreating.
Such shortcoming is arranged here: pin 9 is not continuously or progressively to move but move with fixing increment.Such device can not make the forward position of deflecting coil be fixed on (for example in the middle of) position of regulation all the time, thereby if pin not contact surface 4 beated in the coil forward position, perhaps produce reaction force, push the forward position of separator 12 to rear.Because separator is flexible, reaction force makes deflecting coil be shifted with respect to pipe.Another shortcoming is that pin is pushed down pipe if the promotion amplitude is excessive flared part 4 has not gone back with regard to again moving back.
At United States Patent (USP) 5,185, in 872, the preceding ring (as shown in Figure 2) of separator is equipped with threaded sleeve pipe 24.Having contact head 28 threaded pins 26 can be continuously or progressively be screwed in the sleeve pipe 24.Such shortcoming is arranged: when contact head 28 contacts around the rotation of sleeve pipe longitudinal axis and with the flared part 4 of pipe, transmit moment of torsion in the past deflecting coil is rotated around the z axis of cathode ray tube here.In addition, when pin 26 engaged excessively with sleeve pipe 24, the reaction force that contact head 28 applies may make separator 8 pliable and tough forward position parts 8 be out of shape, thereby deflecting coil is moved relative to cathode ray tube.
According to characteristics of the present invention, it is moved or slip in not threaded sleeve pipe.Like this a sectional area is pressed into hollow parts greater than the wedge spare of pin hollow parts sectional area, thereby prevents the further relative motion of pin in sleeve pipe.
The cathode ray tube deflecting coil that embodies one aspect of the present invention has a lining, and the outer part of the preceding ring of lining has some sleeve pipes.Corresponding pin is inserted in the flared part that in the given sleeve pipe forward position part of deflecting coil is supported on cathode ray tube.The rear portion of pin is hollow, as the shell that pinlock is incorporated into the wedge spare in the set sleeve pipe.
Fig. 1 shows the section that prior art is contained in the deflecting coil on the cathode ray tube.
Fig. 2 shows another embodiment of prior art deflection yoke locking arrangement.
Fig. 3 shows the end view of one embodiment of the invention deflecting coil.
Fig. 4 illustrates in greater detail separator and the position local device of Fig. 3.
Fig. 5 A and 5B are respectively the vertical view and the end view of pin that deflecting coil with Fig. 3 or Fig. 4 is fixed on the flared part of cathode ray tube.
Fig. 6 A and 6B are respectively the vertical view and the end view of the wedge spare in the pin that inserts Fig. 5 A or Fig. 5 B.
Fig. 7 shows another embodiment of steady pin of the deflecting coil of Fig. 3 or Fig. 4.
The deflecting coil 120 of the one embodiment of the invention shown in Fig. 3, and comprise a coil lining or separator 111.The tubular rear portion 165 of the separator 111 of deflecting coil 120 is locked on the neck 160 with clip 175 in the usual way.The preceding ring 110 of separator 111 is supporting sleeve pipe 100.In each sleeve pipe 100, sliding pin 115 inserts and moves in sleeve pipe 100, till the front end of sliding pin touches the flared part 140 of pipe.Pin 115 inserts wedge spare 116 locks in place at its hollow rear portion.The sectional area of wedge spare 116 is greater than the hollow parts of pin.
Fig. 4 shows the part exploded view of Fig. 3 separator.Similarly number similar parts of expression or function element among Fig. 3 and Fig. 4.Among Fig. 4, can see the pin 115 that is supporting deflecting coil front portion 110 insert in the sleeve pipes 100 before and situation afterwards.The locks in place of coil is to assign to finish by the hollow part that wedge spare 116 inserts given sleeve pipe rear portion.
When the position of neck adjusted deflecting coil, deflecting coil is fixed by an external device (ED) (not shown).After sliding pin 115 had inserted in the sleeve pipe 100, deflecting coil just was locked on the neck 160 with clamping clip 175 and (does not show in Fig. 4).Cross section was pushing pin 115 before this greater than a given wedge spare 116 of pin 115 hollow parts, and pin 115 is contacted with tube surface 140.Then wedge spare 116 makes the pin wall radial dilatation of pin 115 by the hollow parts of pin 115, thereby it is locked that pin 115 is withstood the inwall of sleeve pipe 100.At this moment locked on pipe owing to deflecting coil, thereby the external fixation device (not shown) can be decontroled, removed.The benefit of doing like this is, deflecting coil locks in place and do not apply any deflecting coil that impels and insert the reaction force of skew in the process of pins 115 or distortion to ring 110 at locking wedge spare 116.
Can see that from Fig. 5 A, 5B, 6A, 6B and Fig. 7 pin 115 is hollow, roughly be tubular.Similar symbol and numbering similar parts of expression or function element among Fig. 3,4,5A, 5B, 6A, 6B and Fig. 7.Fig. 5 B pin 115 has four slits, 201 each intervals 90 degree, forms on the wall of hollow parts along the part 200 of Fig. 5 A pin 115 length 203.Extend along its longitudinal axis from the rear portion 202 of pin 115 in slit 201, but it is divided into the wall of hollow parts the elastic part of radial dilatation.
The locking wedge spare 116 of Fig. 6 A is tubular along 2/3rds the part 301 that is substantially equal to length 302 and forms, and the forward part 305 of one end is tapered, is convenient to insert the hollow parts of pin 115 and is convenient to make the wall section expansion of pin 115.The advantage of wedge spare 116 is to have a passage 304 to use for injecting glue.Hole 204 in the solation distribution 115 is bonded to each other each parts 100,115 and 116 together and adheres to the surface of pipe.In another embodiment, as shown in Figure 7, each pin 115 has single slit-shaped spirality hole to lead to the rear portion 202 of pin.
In order to change the position of deflecting coil on pipe, may wish to remove the wedge spare 116 of Fig. 3.This can carry out its length greater than pin 115 hollow parts by the length that strengthens wedge spare 116.Like this, deflecting coil during fix in position, outside the outstanding pin 115 of the part of wedge spare 116, is extracted wedge spare 116 out thereby be convenient to extract out in case of necessity ledge on pipe.
