Description
The present invention relates to a kind of deflecting coil, more particularly, relate to of the misconvergence of a kind of compensation arrangement to prevent to cause because of additional magnetic sheet for the in-line gun used for color picture tube.
A kind of compensation arrangement of deflecting coil of routine now is described referring to Fig. 1 to 6.
Fig. 1 illustrates a kind of deflecting coil that is used for the in-line gun chromoscope.This deflecting coil has pair of separated device 10 and 12.This has a pair of neck, a pair of edge 10a and 12a and a pair of hemicone to separator 10 and 12.This is to the electron gun (not shown) of edge 10a and the close chromoscope of 12a.A pair of frame deflector coil 18,18 ' is installed on this a pair of hemicone to separator 10 and 12.A pair of magnetic core 16,16 ' is installed in this on frame deflector coil 18 and 18 '.Electronic circuit board 14 is along this hemicone installing to separator 10,12.A pair of compensating device 20,20 ' forms on edge 10a and 12a.A pair of horizontal deflection coil (not shown) is installed under separator 10 and 12.
Fig. 2 is this perspective view to one of compensating device 20 and 20 '.This respectively has a pair of " L " font rib 22,24 toward each other to compensating device 20,20 ', and has the half- cylindrical rib 26,28 that 22,24 installings of " L " font rib are somebody's turn to do on a pair of edge.Compensation magnetic sheet 30 is made by paramagnetic material, and has a catch 32.Compensation magnetic sheet 30 is pressed between " L " font rib 22,24, and can slide on to semi-cylindrical rib 26,28 at this.Compensation magnetic sheet 30 can be along moving on the detector of fixing catch 32.Fig. 3 is equipped with a pair of compensating device 20 of compensation magnetic sheet 30 and one of 20 ' cross sectional view.Owing to this is arranged to rib 26,28, compensation magnetic sheet 30 just can slide but can not freely be fixed on this to " L " font rib 22,24.
Fig. 4 (A) illustrates how to compensate with respect to the position that compensates magnetic sheet 30 to 4 (D) on chromoscope.In Fig. 4 (A), blue look beam is in the red beam outside.This is called H displacement misconvergence, is that the position difference between the magnetic field center that produced of center and deflecting coil by in-line gun causes.In this case, compensation magnetic sheet 30 should be placed near blue look electron gun one side to compensate this difference, shown in Fig. 4 (B).In Fig. 4 (C), blue look beam then should be placed on compensation magnetic sheet 30 near red gun one side, shown in Fig. 4 (D) in the inboard of red beam.Shown in arrow F10 or F12, the amount of movement of beam spot is controlled by motion compensation magnetic sheet 30.
As mentioned above, this needs a kind of can radially sliding separator 10 and 12 along this to compensating device 20 and 20 ' and compensates magnetic sheet 30, and can be in the structure of its arbitrary desired location fixed compensation magnetic sheet 30.In conventional method, this is parallel to this radially storing to separator 10 and 20 to " L " font rib 22 and 24, so that slide compensation magnetic sheet 30.Should " L " font rib 22,24 and half-cylindrical rib the 26, the 28th be formed respectively, so that can come appropriate fixed compensation magnetic sheet 30 with little space 22A and 24A (Fig. 3).Half-and-half the length of cylindrical rib 26,28 is done to such an extent that be shorter than this " L " font rib 22,24, so that can produce the pressing mold for separator 10,12 usefulness.Disclosing 63-44364/1988 and Japan Patent at Japan Patent discloses and discloses so a pair of compensating device 20 and 20 in the 63-19753/1988.
Above-mentioned so conventional misconvergence compensation method has following shortcoming:
" L " font rib 22 and 24 also needs to have the length in compensation magnetic sheet 30 sliding scales except the width of magnetic sheet 30 that need be on moving direction.Because the pressing mold of production separator 10,12 requires it on the position of rib 22 and 24, particularly must have the narrow shape of Bao Erchang in the position of the ledge 22B of rib 22 and 24 and 24B, so pressing mold is fragile on mechanical performance, be difficult to make.
Because rib 22 and 24 has the narrow shape of Bao Erchang, so its easy deformation is difficult to make.
In the time will compensating magnetic sheet 30 and be pressed in the narrow groove between rib 22 and 24, be difficult to the manual operation of compensation magnetic sheet 30.
Because the direction of insertion of compensation magnetic sheet 30 is restricted, the design of deflecting coil also is restricted.
Because the material of separator 10,12 is made by the plastics of size poor accuracy usually, so be difficult to design and control the production of separator 10,12.
In Fig. 5 (B), the rib 22 of " L " font and 24 has the θ that is called that reduces gradually on the direction of mode cross section
1And θ
2Draw taper (draft).As a result, produced and be designed to big gap, just become difficult so compensation magnetic sheet 30 will be adjusted at desired location.
When producing deflecting coil, use (referring to Fig. 4) a kind of standard demonstration testing tube (not shown) is as previously explained done preliminary the adjustment to each deflecting coil.When producing colour display device, on display tube rather than standard display tube, load onto the deflecting coil of tentatively adjusting.Sometimes between the production pipe in standard pipe and colour display device different machinery and electrology characteristic can appear.At this moment, need the adjustment that an additional correct convergence is lacked of proper care.In order to proofread and correct this misconvergence, need to adopt ancillary relief magnetic sheet 34 as shown in Figure 6, with adhesive 36 this magnetic sheet 34 is fixed on rib 22 and 24.
This additional adjustment has following shortcoming:
This additional compensation magnetic sheet 34 can not temporarily be fixed in its desired location.
When adhesive 36 solidified, this magnetic sheet 34 moved from its fixed position easily.
Because magnetic sheet 34 can not slide and temporarily be fixed on its desired location, so be difficult to magnetic sheet 34 is accurately located.
The present invention establishes in order to address the above problem, and the objective of the invention is to improve the life-span of the pressing mold that separator uses, and makes it have good production efficiency.
