Description

[Detailed description of the invention] (Field of industrial application) This invention is used in electrostatic noise prevention devices, etc., which house a ring-shaped core, pass a cable through its center hole, and wind it several times. This article concerns the core insulation case.

(Prior art) Conventionally, when winding a wire directly around a ring-shaped core, it is necessary to apply insulating paint to the outside to prevent damage to the cable, or to wind a wire in a ring-shaped core with a U-shaped cross section. Conventionally, the core case is butted from both ends, and the ring-shaped core is fixed to the device or device with an adhesive or with a stopper, a nylon cable clamp, etc., and then fixed to the device or device with screws.

(Problems that the invention aims to solve) Conventional methods of applying adhesive require application work, time required for the adhesive to dry, which takes a lot of man-hours, and requires fixing with metal fittings or cable clamps. The problem with this method was that the ring-shaped core inside the core case could not be firmly fixed.

The present invention aims to provide a core insulation case that solves the above problems.

(Means for Solving the Problems) The present invention has an outer cylinder, an inner cylinder, and a lower part that form a storage space for a ring-shaped core, and has a mounting plate extending in a tangential direction from the outer cylinder. A mounting plate is provided with a stepped part and a concave fitting part around the inner wall of the outer cylinder of the case body, which is composed of a fleshed part extending perpendicularly from both ends of the outer cylinder, and a stepped part is provided around the outer wall of the inner cylinder. a case body having a protrusion provided on the fleshed part; and a lid body that closes a storage space for a ring-shaped core of the case body, the body having flesh corresponding to the ring-shaped part and the fleshed part of the case body. The fleshed part of the lid body is provided with a through hole that engages with the protrusion of the fleshed part of the case body, and the ring-shaped part is provided with a through hole that engages with a protrusion of the fleshed part of the case body. The case has a stepped portion and a convex fitting portion that engage with a stepped portion and a concave fitting portion provided around the inner wall, and engages with a stepped portion provided around the outer wall of the inner cylinder of the case body. and a lid body provided with a stepped portion.

(Example) A front view of a case body according to an embodiment of the present invention is shown in Fig. 1, a side view is shown in Fig. 2, and an enlarged view of the A-A cross section is shown in Fig. 3. A front view of the lid of one embodiment is shown in FIG. 4, and an enlarged view of the BB cross section is shown in FIG. The core insulation case of this embodiment will be explained. The case body 1 includes an outer cylinder 2 and an inner cylinder 3.
and the bottom part 4 form a ring-shaped core storage space 5, and has a mounting plate 6 extending in the tangential direction of the outer cylinder, and a mounting plate 6 extending perpendicularly from both ends of the outer cylinder 2 to the mounting plate 6. It has thickened portions 7 and 8, and protrusions 9 and 10 are provided on the thickened portions 7 and 8. A stepped portion 11 and a recessed fitting portion 12 are formed around the inner wall of the outer cylinder 2, and a stepped portion 13 is formed around the outer wall of the inner cylinder 3. Also, the lid body 14
consists of a ring-shaped part 15 and fleshed parts 16 and 17 corresponding to the fleshed parts 7 and 8 of the case body 1, and the fleshed parts 16 and 17 have the fleshed parts 7 and 17 of the case body 1. . A stepped portion 20 that engages with the mating portion 12, a convex fitting portion 21, and a stepped portion 22 that engages with the stepped portion 13 provided around the outer wall of the inner cylinder 3 of the case body 1 are formed. .

The core insulating case of the present invention is used by inserting the ring-shaped core into the case body 1 and closing the lid 14. When the lid body 14 is closed to the case body 1, the stepped portion 11 and the concave fitting portion 12 provided around the inner wall of the outer cylinder 2 of the case body 1, and the stepped portion 20 and the convex portion provided on the lid body 14. A fitting part 21 having a shape of The protrusions 9 and 10 provided on the fleshed parts 7 and 8 of the lid body 1
Through holes 18 provided in the fleshed parts 16 and 17 of 4,
Have 19 insert it. At this time, by engaging the concave fitting part 12 provided around the inner wall of the outer cylinder 2 of the case body 1 with the convex fitting part 21 provided on the lid body 14, the case body 1 is The lid body 14 is fixed. In addition, the fleshed parts 7 and 8 of the case body 1
The protrusions 9, 10 provided in the thickened portions 7, 8 of the lid 14, and the through holes 18, 19 provided in the thickened portions 16, 17 of the lid 14.
By engaging these, the case body 1 and the lid 14 are positioned. In addition, the lid body 14
After attaching to the case body 1, the protrusions 9 and 10 provided on the fleshed parts 7 and 8 of the case body 1 and the lid body 14
Through holes 18, 1 provided in fleshed parts 16, 17 of
It is also possible to apply heat to the area around 9 using a soldering iron or the like to fix the area.

Furthermore, a through hole 23 is formed in the mounting plate 6 of the case body 1, which is effective when fixing the core insulating case to a device or device by screwing or the like.

(Effects of the Invention) The core insulating case of the present invention can easily fix a ring-shaped core without using an adhesive, and can be easily attached to equipment, etc., and is extremely useful industrially.
