Description

[Detailed description of the invention] This invention relates to a chucked east line covering sheet, and more specifically, for example, a chucked east line covering sheet for degaussing coils etc. that simplifies the covering and shaping of degaussing coils attached to color cathode ray tubes. This invention relates to improvements in covering sheets.

Conventionally, color cathode ray tubes have been equipped with degaussing coils in order to prevent deterioration of color resolution due to unnecessary external magnetic fields such as earth's magnetism.

Conventional degaussing coils consist of 10 to 2 enamel insulated conductors.
After winding the coil 0 times to form a coil, the coil is removed from the winding frame, an insulating tape is wrapped around the coil in a toroidal shape, and then formed into a rectangular shape for mounting on a cathode ray tube. was.

In order to solve the extremely poor workability of wrapping insulating tape in a toroidal shape around the outer circumference of the coil,
A conductive sheet and an insulating sheet are stacked and rolled into a cylindrical shape, and then cut to a predetermined width to form a ring-shaped coil.The coil is then immersed in an insulating resin solution and dried to form an insulating coating around the outer periphery. A degaussing coil has been proposed.

However, in this case, various types of equipment and processes are required, such as overlapping the conductive sheet and the insulating sheet, cutting them, dipping them in a resin solution, and drying them, and the workability is not necessarily improved.

The purpose of this invention is to eliminate the above-mentioned drawbacks.The main feature of this invention is that a semi-hard resin is attached to both edges of a band-shaped member made of soft synthetic resin, and one side of the belt-shaped member is made of semi-hard resin. By forming a convex portion and a concave portion into which the convex portion fits on the other side edge side to form a chuck portion, and cutting the longitudinal edge of the strip member diagonally,
The present invention provides an east line covering sheet with a chuck, which is configured such that the end edges of the band-like member can be temporarily fixed together through the chuck portion.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 a s b is an enlarged perspective view of the covering sheet 1 that wraps around the East Line coil, for example, the circular East Line coil, which is a feature of this invention. A first plate made of semi-hard synthetic resin is integrally formed with the sheet-like member 11 on one side edge of the belt-like sheet-like member 11 having an equal width and a length corresponding to the mounting position on the cathode ray tube.
a base portion 12 and a riveted convex portion 13 in the center of its width;
A second platform 14 made of semi-hard synthetic resin is formed integrally with the sheet-like member on the other side edge of the sheet-like member, and the rivet-head-shaped recess 15 is formed at the center of its width, and the convex portion 1 is formed integrally with the sheet-like member.
3 and the recessed part 15 can form a chuck part 16.

Incidentally, at both ends of the sheet-like member 1 in the longitudinal direction, as shown in FIG.
Form A, I and B respectively.

As shown in FIG. 2a, this invention utilizes the convex portions 13 and concave portions 15 of the diagonally cut portions IA and IB of the cover sheet 1 to temporarily fix the cover sheet 1, and moves the zipper 4 in the direction of the arrow. The degaussing coil 3 is wrapped in the cover sheet 1 by aligning the base parts 12 and 14 of the two and fitting the convex part 13 into the concave part 15, as shown in FIG.

The coated degaussing coil 5 is connected to the degaussing coil 3 as shown in FIG.
The starting end 3A of the coil 3 and the ending end 3B of the coil 3 are shaped as follows.
The connector 33 is connected to the leader wire 32 attached to the above-mentioned joint part of the covering sheet, and this leader wire is pulled out to the outside at the joint part, and this part is fixed with a fastening band 34, as shown in FIG. Form as shown.

The coated degaussing coil 5 completed in this way has a cross-sectional shape as shown in FIG. 4, and has been formed as shown in FIG. Chuck part 1
It is used by being inserted between a pair of upright ribs at intervals approximately equal to the width of 6@.

As mentioned above, this invention is based on a belt-shaped member made of soft synthetic resin, with a convex part made of semi-hard resin integrally formed with the member on one side, and the convex part fitted on the other side. A recess is formed to constitute a chuck part, and the edges of the belt-like member in the longitudinal direction are cut diagonally, so that the ends of the belt-like member can be temporarily fixed to each other via the chuck part. Therefore, the covering of the east line, especially the beginning and end of the covering of the circular east line, can be temporarily fixed, and the effect is that it can be chucked and covered very easily.
