Description
Technical field
The present invention relates to a kind of assembling operation easily and be difficult for producing the deflecting coil and the manufacture method thereof of defective, particularly relate to a kind ofly, can make assembling operation easily and avoid producing the deflecting coil and the manufacture method thereof of defective by improving horizontal deflection coil.
Background technology
Deflecting coil has a pair of horizontal deflection coil, a pair of frame deflector coil, is used to make the separator of horizontal deflection coil and vertical deflection mutual insulating.Horizontal deflection coil is installed in inner face side, and frame deflector coil is installed in the exterior side of bearing pedestal.Figure 12 is the oblique view of the general saddle type horizontal deflection coil 2 of expression.As shown in figure 12, horizontal deflection coil 2 is made of the lateral parts 2c of small diameter portion 2a, major diameter part 2b, connection small diameter portion 2a and major diameter part 2b.Small diameter portion 2a and major diameter part 2b form the outstanding flange of blade of a sword shape.The middle body of the horizontal deflection coil 2 that is centered on by small diameter portion 2a, major diameter part 2b and lateral parts 2c forms window portion 2d.
As everyone knows, horizontal deflection coil 2 is wound in as shown in figure 12 shape with a lead, draws the coiling initiating terminal 2s and the coiling clearing end 2f of lead from horizontal deflection coil 2.Coiling clearing end 2f draws from the surface of small diameter portion 2a, and coiling initiating terminal 2s draws near the end of small diameter portion 2a one side of the window portion 2d of part 2c from the side.The surface that forms the lead of horizontal deflection coil 2 forms fused layer, if the coil winding machine of not representing among the figure forms after the horizontal deflection coil, to horizontal deflection coil 2 energisings, makes its heating, solidifies thereby make to merge between each lead.Thus, make horizontal deflection coil 2 integrated.
Below the formation method of the window portion 2d of horizontal deflection coil 2 is described.As everyone knows, horizontal deflection coil 2 is by having the coil winding machine formation shape as shown in figure 12 of formpiston and former.At this moment, as shown in figure 13, make block 51 outstanding, thereby form window portion 2d from formpiston.The shape of block 51 has determined the shape of window portion 2d.
As mentioned above, the horizontal deflection coil 2 that forms by said method is installed in the inner face side of bearing pedestal.Bearing pedestal is assembled by for example Semicircular bearing pedestal halfbody, forms funnel-form.Below utilize Figure 14～Figure 16, the method that horizontal deflection coil 2 is installed on the bearing pedestal describes.Figure 14 is that horizontal deflection coil 2 is in the partial side view's (flange of small diameter portion 2a is decided what is right and what is wrong) under the inner face side state that is installed in bearing pedestal halfbody 1H, Figure 15 is the A-A cutaway view of Figure 14, and Figure 16 is the partial sectional view of the state after 1 assembling of expression bearing pedestal.In Figure 15 and Figure 16.For easy to understand, at horizontal deflection coil shown in the end view 2, rather than shown in the cutaway view.
In Figure 14 and Figure 15, upside is minor diameter one side of deflecting coil, and downside is major diameter one side of deflecting coil.Bearing pedestal halfbody 1H (bearing pedestal 1) has a plurality of (being two herein) smaller diameter side flange 1a.Form container cavity 1c between two flange 1a, the flange of the small diameter portion 2a of horizontal deflection coil 2 just is contained in the container cavity 1c.As shown in Figure 15, bearing pedestal halfbody 1H has to the outstanding plate rib 1d of bearing pedestal 1 internal direction.This plate rib 1d is used to make the coiling initiating terminal 2s of horizontal deflection coil 2 and coiling clearing end 2f to separate, to guarantee insulation distance each other.In addition, have the potential difference about 1.2kV between coiling initiating terminal 2s and the coiling clearing end 2f, must positively prevent short circuit.
For Figure 14 of horizontal deflection coil 2 and the state of Figure 15 are installed on a bearing pedestal halfbody 1H, when another bearing pedestal halfbody of assembling 1H, as shown in figure 16, plate rib 1d overlaps each other together.Wherein, omitted the part diagram of major diameter one side of the flange 1a of bearing pedestal 1, bearing pedestal 1 has held all of horizontal deflection coil 2.Because plate rib 1d overlaps each other,, thereby guaranteed the insulation effect between coiling initiating terminal 2s and the coiling clearing end 2f effectively so the creepage distance between the coiling initiating terminal 2s of horizontal deflection coil 2 and the coiling clearing end 2f becomes big.
As shown in figure 16, when two bearing pedestal halfbody 1H fit together, when the inner face side of bearing pedestal 1 is held a pair of horizontal deflection coil 2, because coiling initiating terminal 2s is near plate rib 1d, so exist coiling initiating terminal 2s may be clipped in two problems between the plate rib 1d.In addition, even coiling initiating terminal 2s is not stuck between the plate rib 1d, plate rib 1d also may make coiling initiating terminal 2s sustain damage, thereby produces defective.
In order to address the above problem, the operator of assembling deflecting coil makes coiling initiating terminal 2s away from plate rib 1d, promptly carries out so-called shaping processing, but can cause the assembling operation of deflecting coil to increase like this.In addition, promptly be to form processing, can not address the above problem at all.
In recent years, in order to reduce the consumption electric power of deflecting coil, make the end of minor diameter one side of window portion 2d of horizontal deflection coil 2 close to small diameter portion 2a.When the smaller diameter side end of window portion 2d during near small diameter portion 2a, the interval between coiling initiating terminal 2s and the coiling clearing end 2f dwindles, and is easier to take place the problems referred to above, so wish urgently to be improved.
The present invention proposes in view of the above problems, its objective is provides a kind of deflecting coil and manufacture method thereof, deflecting coil for horizontal deflection coil with lead-out wire, lead-out wire can be clipped in the rib of the insulation usefulness that is arranged on the bearing pedestal, and can make assembling operation easy, avoid producing defective.

(first execution mode)
At first, the whole configuration example to deflecting coil of the present invention describes.In Fig. 5, the bearing pedestal 1 of deflecting coil by combining by for example a pair of Semicircular bearing pedestal halfbody 1H, diameter is bigger to form a side (downside among Fig. 5), and the less funnel-form of opposite side (upside among Fig. 5) diameter.Wherein, diameter major part is the picture side of cathode ray tube, and smaller-diameter portion is the axle journal side.Bearing pedestal 1 is made by sex change PPE (polyphenylene oxide) or PP resins such as (polypropylene).Smaller diameter side and larger diameter side at bearing pedestal 1 form flange 1a, 1b respectively.
The inner face side of this bearing pedestal 1 be equipped with the horizontal deflection coil 20 of a pair of saddle type ', at its exterior side the frame deflector coil 3 of a pair of saddle type is installed, bearing pedestal 1 make horizontal deflection coil 20 ' and frame deflector coil 3 keep electric insulations.The iron core 4 that is made of ferrite etc. is installed in the outside of frame deflector coil 3.
The deflecting coil of above-mentioned formation need be revised the circuit of deflection characteristic usually, and a pair of substrate 5 that carries foregoing circuit is installed in the side of bearing pedestal 1.Owing to be loaded high voltage in the circuit of substrate 5, thus in order to prevent to get an electric shock and circuit etc. to be protected, on circuit board 5, covered the protective cover of making by insulating material, shown here for opening the state of protective cover.
Below to as the horizontal deflection coil 20 of feature of the present invention ' be elaborated.Fig. 1 represent horizontal deflection coil 20 ', this horizontal deflection coil 20 ' be is processed by horizontal deflection coil 20 as shown in Figure 2.
At first, utilize Fig. 2 that horizontal deflection coil 20 is described.As shown in Figure 2, horizontal deflection coil 20 is made of two lateral parts 20c of small diameter portion 20a, major diameter part 20b, connection small diameter portion 20a and major diameter part 20b.When the direction of winding of the lead of small diameter portion 20a was first direction, the direction of winding of the lead of major diameter part 20b was the second direction opposite with first direction.The direction of winding of the lead of lateral parts 20c is the direction of roughly intersecting with first direction and second direction.Small diameter portion 20a and major diameter part 20b form the outstanding flange of blade of a sword shape.The middle body of the horizontal deflection coil 20 that is centered on by small diameter portion 20a and major diameter part 20b and lateral parts 20c forms window portion 20d.
In the first embodiment, make the shape of window portion 20d have following feature.As shown in Figure 2, window portion 20d minor diameter one side forms the mountain shape of projection.Form sloping portion 20d2, the 20d2 that is roughly linearity to tilted direction from the end 20d1 (smaller diameter side end 20d1) of minor diameter one side of window portion 20d.The terminal of sloping portion 20d2,20d2 forms sweep 20d3, the 20d3 to the outer direction projection of horizontal deflection coil 20.End 20d4, the 20d4 of window portion 20d one side of sweep 20d3,20d3 and lateral parts 20c (side end 20d4) links together.Draw the coiling initiating terminal 20s and the coiling clearing end 20f of lead from horizontal deflection coil 20.
After the coiling of horizontal deflection coil 20 is finished, horizontal deflection coil 20 becomes the state of the Fig. 2 before the processing, coiling clearing end 20f draws from the surface of small diameter portion 20a, and coiling initiating terminal 20s draws near the smaller diameter side end 20d1 of window portion 20d among the part 20c from the side.The surface that forms the lead of horizontal deflection coil 20 is formed fused layer.When by (horizontal deflection coil winding process) after the coil winding machine of expression does not form horizontal deflection coil 20 among the figure, to horizontal deflection coil 20 energisings, make its heating, merge between lead thus and solidify, make horizontal deflection coil 20 integrated (fusion curing process).
Behind the horizontal deflection coil 20 that forms as shown in Figure 2, horizontal deflection coil 20 is processed by for example handwork.That is, the lead that forms horizontal deflection coil 20 is a starting point with coiling initiating terminal 20s, near the 20d1 of top along sloping portion 20d2, wind the line to side end 20d4 through sweep 20d3 from sloping portion 20d2 then.Then, by the initiating terminal 20s that winds the line along sloping portion 20d2 tension, a part that is merged the lead that the coiling initiating terminal 20s of curing extends along sloping portion 20d2 is stripped from specific length, becomes horizontal deflection coil 20 ' (stripping process) as shown in Figure 1.As shown in Figure 1, will be in the coiling initiating terminal 20s that has peeled off a part of state that is merged the lead that solidifies and be called coiling initiating terminal 20s '.
Therefore, the feature of deflecting coil of the present invention is, the assembling of the inner face side of bearing pedestal 1 from the horizontal deflection coil 20 of drawing coiling initiating terminal 20s ' by the position of smaller diameter side end 20d1 deflection major diameter one side of window portion 20d ', rather than in the inner face side assembling of bearing pedestal 1 from drawing the horizontal deflection coil 20 of coiling initiating terminal 20s near the smaller diameter side end 20d1 of window portion 20d.
In above example, as a method from drawing coiling initiating terminal 20s ' by the position of the smaller diameter side end 20d1 of window portion 20d deflection major diameter one side, at first form from drawing the horizontal deflection coil of coiling initiating terminal 20s near the smaller diameter side end 20d1 of window portion 20d, part by the lead that will merge be solidified be peeled off, form horizontal deflection coil 20 with coiling initiating terminal 20s ' '.In the method, for from drawing coiling initiating terminal 20s near the smaller diameter side end 20d1 of window portion 20d, still use common coil winding machine, can form the horizontal deflection coil 20 that has from the coiling initiating terminal 20s ' that draws by the position of the smaller diameter side end 20d1 of window portion 20d deflection major diameter one side '.
As another method, can improve coil winding machine, be partial to the position of major diameter one side from smaller diameter side end 20d1 and draw coiling initiating terminal 20s ' by window portion 20d.
Below the effect that sweep 20d3 is set on the end face of the window portion 20d of lateral parts 20c one side is described.Fig. 4 is the performance plot that the peel resistance when being merged the lead that solidifies is peeled off in expression, and its expression is crossed the resistance of sweep 20d3 when side top 20d4 peels off lead from the smaller diameter side end 20d1 of window portion 20d.Transverse axis is represented the position of lead, and the longitudinal axis is represented peel resistance (kg).As shown in Figure 4, when from the smaller diameter side end 20d1 of window portion 20d when sweep 20d3 peels off lead, resistance increases 4 times sharp at sweep 20d3, increasing from about 0.5 (kg) is 2.0 (kg).
The great reason of resistance when lead is peeled off at sweep 20d3 place is, in forming the winding process of window portion 20d as shown in Figure 3, the stronger pressure of sentencing than sloping portion 522 and lateral parts 524 at the corner angle 523 of block 52 of straight line portion makes fluid-tight engagement between the lead, thereby merges securely.When the operator peels off lead, pinch coiling initiating terminal 20s with finger, if pull with the strength that can peel off straight line portion, then resistance becomes greatly at sweep 20d3 place, stops at sweep 20d3 place so peel off mostly.Perhaps, when the operator feels very big resistance,, then can not surpass sweep 20d3 and peel off lead if desire to stop to peel off.
Therefore,, can prevent excessively peeling off of lead, set the position of drawing coiling initiating terminal 20s ' roughly the samely by sweep 20d3 being set at window portion 20d (end of window portion 20d one side of lateral parts 20c).Thus, horizontal deflection coil 20 ' characteristic can not disperse.The position of sweep 20d3 can be set in from the appropriate location of smaller diameter side end 20d1 deflection major diameter one side of window portion 20d.By changing the shape of block 52 as shown in Figure 3, can be arbitrarily and easily set the position of sweep 20d3.Sweep 20d3 is the device that resistance is increased.
Carried out after the above-mentioned operation, will pass through the horizontal deflection coil 20 of wire stripping operation ' the be installed in inner face side (assembling procedure) of bearing pedestal 1, the final deflecting coil that forms as shown in Figure 5.
Below utilize Fig. 6～Fig. 8 that the installation method with horizontal deflection coil 20 ' install on the bearing pedestal 1 is described.Fig. 6 is in inner face side state with horizontal deflection coil 20 ' the be installed in bearing pedestal halfbody 1H partial side view of (flange fracture of small diameter portion 20a) of partly rupturing, Fig. 7 is the B-B cutaway view of Fig. 6, and Fig. 8 is the partial sectional view of the state after the expression assembling bearing pedestal 11.In Fig. 7 and Fig. 8, for easy to understand, horizontal deflection coil shown in the end view 20 ', rather than cutaway view.
In Fig. 6 and Fig. 7, upside is minor diameter one side of deflecting coil, and downside is major diameter one side of deflecting coil.Bearing pedestal 1 (bearing pedestal halfbody 1H) has multi-disc (being two herein) smaller diameter side flange 1a.Between two flange 1a, form container cavity 1c, horizontal deflection coil 20 ' the flange of small diameter portion 20a be contained in the container cavity 1c.As shown in Figure 7, bearing pedestal halfbody 1H has to the outstanding plate rib 1d of bearing pedestal 1 internal direction.This plate rib 1d be used for horizontal deflection coil 20 ' coiling initiating terminal 20s ' and coiling clearing end 20f keep apart, to guarantee insulation distance each other.
For on a bearing pedestal halfbody 1H, install horizontal deflection coil 20 ' Fig. 6 and the state of Fig. 7, when another bearing pedestal halfbody of assembling 1H, as shown in Figure 8, plate rib 1d coincides together mutually.Wherein, omitted the part diagram of major diameter one side of the flange 1a of bearing pedestal 1, bearing pedestal 1 held horizontal deflection coil 20 ' all.Because plate rib 1d overlaps each other, thus horizontal deflection coil 20 ' coiling initiating terminal 20s ' and the creepage distance between the coiling clearing end 20f become big, thereby guaranteed the insulation effect between coiling initiating terminal 20s ' and the coiling clearing end 20f effectively.
At above-mentioned two the bearing pedestal halfbody 1H of assembling, in the assembling procedure with the inner face side of a pair of horizontal deflection coil 20 ' be contained in bearing pedestal 1, because 20s ' is far away from plate rib 1d for the coiling initiating terminal, so coiling initiating terminal 20s ' can not be stuck between two plate rib 1d.In addition, plate rib 1d can not damage coiling initiating terminal 20s ' yet, thereby produces defective.In addition, the operator of assembling deflecting coil needn't make the operation of coiling initiating terminal 20s ' away from plate rib 1d, makes the stripping process of peeling off lead become simply, thereby can simplify the assembling operation of deflecting coil.
But, when near the 20d1 of end when sloping portion 20d2 peels off lead, at the left lateral sides part 20c of the Fig. 1 with the sloping portion 20d2 that peels off lead with have on the lateral parts 20c on right side of Fig. 1 of the sloping portion 20d2 that does not peel off lead, a difference is arranged for its number of lead wires of sloping portion 20d2 part.Therefore, connect horizontal deflection coil 20 ' small diameter portion 20a and the left and right sides deflection characteristic of the center line of major diameter part 20b be different.When peeling off the lateral parts 20c of lead one side, deflection center is offset laterally.
Peel off lead and produce under the situation of the problem that deflection characteristic changes occurring being accompanied by, preferred embodiment as follows.Fig. 9 represents the state of unstripped lead.In Fig. 9, on the sloping portion 20d2 on the right side of unstripped lead, the lead in interior week of position shown in the dotted line is caved in to position shown in the solid line.Like this, when making, the sloping portion 20d2 in the left side winds the line in advance when peeling off lead, so that the deflection characteristic of left and right side part 20c is roughly the same.
Like this, under the state of having peeled off lead, by preestablishing the shape of horizontal deflection coil 20, make horizontal deflection coil 20 ' the left and right sides deflection characteristic of center line roughly the same.That is, for the horizontal deflection coil 20 that carries out before the wire stripping operation, the shape that makes two lateral parts 20c is asymmetric for the center line of horizontal deflection coil 20.As other method, under the state of having peeled off lead, can make the distribution density of lead of two lateral parts 20c asymmetric for the center line of horizontal deflection coil 20, thus make horizontal deflection coil 20 ' the left and right sides deflection characteristic of center line roughly the same.Specifically, sparse by near the arrangement of conductors density the sloping portion 20d2 that makes unstripped lead one side, thus optimize deflection characteristic.
(second execution mode)
In the above-described first embodiment, the method for the resistance when peeling off lead as increase has been used sweep 20d3, but also can use additive method.Figure 10 partly show the horizontal deflection coil 21 of second execution mode '.Horizontal deflection coil 21 ' be in has been peeled off the state after the lead.Horizontal deflection coil 21 ' shape identical with horizontal deflection coil 2 shown in Figure 12.Horizontal deflection coil 21 ' be made of small diameter portion 21a, major diameter part (not shown) and two lateral parts 21c, middle body is made of window portion 21d.In Figure 10,21f is the coiling clearing end, and 21s ' is for having peeled off the coiling initiating terminal of lead.Be wound with adhesive tape 60 on the lateral parts 21c.
The coiling initiating terminal of peeling off before the lead is called 21s.When pullling coiling initiating terminal 21s, owing on lateral parts 21c, be wound with adhesive tape 60, so the resistance when peeling off lead increases being wound with adhesive tape 60 places with wire stripping.Therefore, peeling off at adhesive tape 60 places of lead stops.In addition, also Continuous pressing device for stereo-pattern 60 on lateral parts 21c not, and paste the adhesive tape of small pieces in the end of window portion 21d one side.In second execution mode,, have shortcomings such as paste position departs from easily, so preferred first execution mode owing to need the operation of Continuous pressing device for stereo-pattern 60.
(the 3rd execution mode)
Figure 11 partly illustrate the horizontal deflection coil 22 of the 3rd execution mode '.Horizontal deflection coil 22 ' be in has been peeled off the state after the lead.Horizontal deflection coil 22 ' shape identical with horizontal deflection coil 2 shown in Figure 12.Horizontal deflection coil 22 ' be made of small diameter portion 22a, major diameter part (not shown) and two lateral parts 22c, middle body is made of window portion 22d.In Figure 11,22f is the coiling clearing end, and 22s ' is for having peeled off the coiling initiating terminal of lead.As shown in figure 11, stop the position formation sunk part 70 of wire stripping in hope.The effect of this sunk part 70 also is the resistance that increases when peeling off lead.
During winding process or after the coiling end,, can form sunk part 70 at an easy rate by placing pin.In the 3rd execution mode, owing to need to form the operation of sunk part 70, so preferred first execution mode.
In the embodiment of the present invention of above explanation, coiling clearing end 20f, 21f, 22f draw from the surface of small diameter portion 20a, 21a, 22a, coiling initiating terminal 20s, 21s, 22s from the side part 20c, 21c, 22c window portion 20d, 21d, 22d near draw, but the present invention is not limited thereto.Also coiling initiating terminal 20s, 21s, 22s can be drawn from the surface of small diameter portion 20a, 21a, 22a, with coiling clearing end 20f, 21f, 22f from the side part 20c, 21c, 22c window portion 20d, 21d, 22d near draw.In addition, horizontal deflection coil also can be the non-flexure type horizontal deflection coil that does not form flange at small diameter portion 20a, 21a, 22a.
