Description

A kind of coil clamp

The present invention relates to a kind of coil clamp of clamping coil, more particularly, relate to a kind of anti-magnetized coil folder, its clamping is around on the cathode ray tube circumferential edge to reduce the anti-magnetized coil of generation of static electricity.

As shown in Figure 5, the cathode ray tube 18 of television set is fixed on the housing 16 of television set by support 28, and support 28 stretches out from four angles of cathode ray tube 18.

Because cathode ray tube 18 produces static in when magnetization, so anti-magnetized coil 42 is around on the circumferential edge of cathode ray tube 18 to reduce static.

Traditional way is also to adopt in the coil clamp 60 of Fig. 6 to come clamping anti-magnetized coil 42.This coil clamp 60 comprises that one is loaded on the fixture 62 in the engaging hole of being located on each support 28 and the bent folder 64 of a clamping anti-magnetized coil 42.This fixture 62 and bent folder 64 and a plate shape substrate 66 that approaches integrally connect together, because fixture 62 must press fit in each engaging hole of support 28 through the narrow gap between housing 16 and cathode ray tube 18.

The position of anti-magnetized coil 42 and the number of turns are determined according to the specification of cathode ray tube 18, so that reduce the static that is produced by cathode ray tube 18 effectively.

Yet in habitual coil clamp 60, coil 42 is tending towards entering the triangular space 70 of formation between the pressure tongue spare 68 of folder 64 and long substrate 66.Therefore, habitual coil clamp 60 exists the anti-magnetized coil 42 of reeling to depart from tram and anti-magnetized coil in a single day to enter gap 70 and just be difficult to take out, and makes problems such as the work of safeguarding anti-magnetized coil 42 bothers very much.

The thickness of the support 28 of cathode ray tube 18 is according to the difference of the specification of cathode ray tube 18 and pattern and difference, yet, the top of the elastic claw 72 of fixture 62 and the gap between the flange 74 are immutable, therefore, habitual coil clamp 60 can not adapt to the variation of support 28 thickness, therefore can produce play.

The present invention has finished and has addressed the above problem, and its objective is provides a kind of coil clamp, and this coil clamp can be clamped in coil or analog and gives allocation, and it can adapt to the substrate of intrinsic coil clamp on it, the variation of the thickness of support or flange.

Coil clamp of the present invention is used for collecting and holds the anti-magnetized coil on the circumferential edge of the cathode ray tube that is distributed in housing, and elastic claw is loaded in the connecting hole on the support that is located at cathode ray tube.

Coil clamp of the present invention is used to keep the coil that twines.This coil clamp comprises:

A prolate substrate;

Be located at a flange of this prolate substrate one end;

Give prominence to also the approaching elasticity bluff piece of elasticity each other from this flange;

A curved clamp band that extends from this long substrate, with this long substrate form this anti-magnetized coil of clamping grasping part; With

Press tongue from one of oblique this grasping part opening extension of this long substrate;

This coil clamp is connected in connecting hole by this elastic claw and this flange;

This coil clamp also comprises the part of being located between this pressure tongue and this long substrate near the gap location of this grasping part that prevents, prevents that this coil from entering this gap;

In coil clamp of the present invention, preferably this prevents that part from being made of a set square, and this plate presses a side of tongue to extend to this long substrate from this, so that can allow this pressure tongue to long substrate bending.

In coil clamp of the present invention, preferably this flange is provided with an arc spring spare, and this spring spare is that periphery of the bottom of this flange and bottom surface are cut formation, makes this spring spare extend and suspended by this flange along the periphery of flange.Therefore, when this bullet spare pawl during with this connecting hole engagement of being formed on the support of cathode ray tube, this spring spare flexibly contacts with the circumferential edge of this connecting hole.

In coil clamp of the present invention, pack into the connecting hole of support of cathode ray tube in the elastic claw interference fit ground that stretches out from flange.When elastic claw passed through connecting hole, they flexibly recovered its original shape, so that the circumferential edge of connecting hole is remained between the free end and flange of elastic claw.By this operation, coil clamp and the engagement of the support between housing and cathode ray tube.

Afterwards, anti-magnetized coil press is inserted in the grasping part that is formed by the coil clamp circle, simultaneously with it on the circumference of cathode ray tube.Because press tongue to bend towards long substrate flexibly by anti-magnetized coil, the opening of grasping part is just widened, and whereby, is convenient to the push operation of anti-magnetized coil.

Be located at the triangular space place of extending between tongue and the long substrate because prevent part, can prevent that just the demagnetization circle from entering this gap pressing.This can prevent the position deviation of anti-magnetized coil, therefore, the demagnetization circle is remained on give fixed position.

In coil clamp of the present invention, prevent that part is by constituting to the set square that long substrate extends from the side of pressing tongue.In this example, anti-magnetized coil is prevented from entering in the triangular space of pressing between tongue and long substrate by the side of this set square.Because the set position of this set square makes that even it does not interfere with long substrate yet when pressing tongue crooked, so press tongue bending maturely.

In coil clamp of the present invention, flange is provided with a spring part, and it flexibly contacts with the circumferential edge of connecting hole when elastic claw meshes with connecting hole.Therefore, coil clamp can adapt to the variation of the thickness of the support that connecting hole is arranged, and therefore, coil clamp can not have play with the connecting hole engagement.

Spring part has along the arc of flange periphery extension and is cantilever, therefore, spring part is not outstanding from the flange circumference, therefore, when the elastic claw that stretches out from flange is pressed into connecting hole by the narrow gap between housing and the cathode ray tube, thereby can stop spring part to contact or the visibility overslaugh that reduces connecting hole is pressed into operation with shell spare or cathode ray tube.

Referring now to accompanying drawing embodiments of the invention are described in detail as follows.

As depicted in figs. 1 and 2, the coil clamp 10 of present embodiment is provided with the long substrate of flexibility or the support 12 of thin strip, and the rear end of widening of long substrate 12 is provided with the anti-skidding lateral slot 14 that forms on the relative both side surface in rear end.When gap between housing 16 and the cathode ray tube 18 is inserted at tip that will long substrate 12, there is the part of lateral slot 14 to pinch (see figure 5) in finger.

On the top of long substrate 12, a circular flange 20 is set obliquely with respect to the longitudinal axis of long substrate 12.Because flange 20 tilts, flange 20 can closely contact with the surperficial of support 28 at each the angle of bend place that is located at cathode ray tube 18.

Shown in Fig. 3 and 4, flange 20 is provided with cantilever spring part 24 in its underpart.Again specifically, be shaped on a plurality of grooves 22 in its axial middle body position, and this groove is along circumferentially extending at the circumferential surface of flange 20.In addition, the bottom of flange 20 is cut forms a plurality of barbed portion communicate with this groove 22, and makes the some parts of left of this bottom be parallel to the radial transmission line extension, whereby, forms the part 24 of some springs.The free end of the part 24 of these springs is provided with the ledge 26 of downward extension.These ledges 26 contact with the periphery of the connecting hole 32 of support 28, and support 28 extends out from cathode ray tube 18 corresponding four angles.

A cylinder base 30 is outstanding from the middle body of the bottom of flange 20, and its profile is suitable for inserting connecting hole 32.One laminar supporting leg 34 extends axially from cylinder base 30.

One elastic claw 36 is located at the top of supporting leg 34.The top of elastic claw 36 is towards the 30 oblique extensions of cylinder base, and the distance between pawl 36 each top increases gradually.Be formed with shoulder part 38 on the top of each elastic claw 36, this shoulder part 38 meshes with the circumferential edge of the connecting hole 32 of support 28.

In addition, a curved clamp band 40 is extended out by the part near long substrate 12 tops, so, the grasping part 44 of a clamping anti-magnetized coil of formation between curved clamp band 40 and long substrate 12.
