The terms "first," "second," and the like, herein are used for convenience in describing two or more structures or components that are identical or similar in structure and/or function and do not denote any particular limitation in order and/or importance.

Before describing the specific structure of the coil protector of the present application, the specific structure of the current coil 01 will be described.

As shown in fig. 3, the current coil 01 generally comprises a plurality of turns, each turn is referred to as a coil segment 011, and a gap between two adjacent coil segments 011 is referred to as a turn gap. In this embodiment, current coil 01 has three turns of coil segment 011.

The utility model provides a coil protector of electronic product, including protection casing 1, the inner wall of protection casing 1 is provided with two protruding muscle 2, and protection casing 1 can cover in the at least part region of current coil 01 periphery, and protruding muscle 2 can correspond the cartridge respectively in the turn clearance of current coil 01, offsets with the turn coil section 011 of both sides.

In the coil protection device of the utility model, the protection cover 1 plays a role in positioning, so that the convex rib 2 can be stably positioned at the installation position, and the convex rib 2 separates two adjacent coil sections 011, even if suction is generated between the coil sections 011, the coil sections 011 can not be distorted and deformed due to the limiting action of the convex rib 2, and the coil insulation is prevented from being damaged, thereby avoiding the occurrence of situations such as coil short circuit and burnout, and improving the safety performance; meanwhile, the protection device is simple in structure, convenient to install, low in cost and high in practicability.

The number of the convex ribs 2 is related to the number of turns of the current coil 01, specifically, the number of the convex ribs 2 should be equal to the number of turns of the current coil 01 minus one, for example, when the number of turns of the current coil 01 is two, only one convex rib 2 needs to be arranged; therefore, in practical applications, the number of the coil guard provided with the ribs 2 may be at least one.

In the embodiment, the number of the protective covers 1 is one, and the two convex ribs 2 are arranged on the inner side of the same protective cover 1; in practical application, the number of the protective covers 1 can be multiple, the protective covers 1 are distributed along the axial direction of the current coil 01, and at least one convex rib is arranged on the inner side wall of each protective cover 1; in other words, in practical applications, the number of the protective covers 1 may be at least one. Of course, the protection cover 1 needs to be installed for a plurality of times for a plurality of embodiments, and stability is relatively poor, and the embodiment of this embodiment, simple structure, only need install once can, it is more simple and convenient, and the stability of installing back coil protector is better, for more preferred technical scheme.

The utility model discloses in, the thickness of protruding muscle 2 should equal with the width in the clearance of current coil 01 circle, so, when protruding muscle 2 cartridge was in the clearance of current coil 01 circle, can offset with both sides circle coil section 011. It can be understood that, due to the existence of the machining error, a gap inevitably exists between the rib 2 and the two adjacent coil segments 011, and in practical applications, the gap between the rib 2 and the two coil segments 011 should be as small as possible.

The coil protection device is preferably made of an insulating material, including but not limited to plastics, and can be integrally formed by injection molding, so that the processing is convenient, and the cost is reduced.

It can be understood that if the protection cover 1 and the convex rib 2 are of an annular structure, the protection cover 1 is sleeved with the circuit coil 01, the convex rib 2 completely isolates the coil sections 011 on two sides along the circumferential direction, and the technical scheme is more ideal, but in practical application, the technical scheme makes the installation process become more complicated and is not easy to realize. Therefore, as shown in fig. 2, in the present embodiment, the protective cover 1 is provided in a U shape, and an opening end thereof forms an insertion opening through which the current coil 01 can be installed inside the protective cover 1, so that the installation is more convenient; the convex rib 2 is also U-shaped in the axial projection plane and is inserted into the turn gap along with the protective cover 1, and meanwhile, the sum of the side lengths of the convex rib 2 is not less than three fourths of the length of the turn coil section 011, so that the deformation of the area which is not isolated can not be caused, the safety problem is avoided, and the safety performance is improved.

Wherein the length of the turn coil section 011 is defined as: a length extending from a predetermined position of one of the coil segments 011 to the same position of the adjacent one side coil segment 011.

The shapes of the protective cover 1 and the convex ribs 2 adopt the U shape, and are based on that the current coil 01 in the embodiment is square in an axial projection plane; in practical applications, the shape of the shield 1 and the rib 2 should be consistent with the shape of the current coil 01, for example, the current coil 01 is circular in the axial projection plane, and the shape of the shield 1 and the rib 2 should be circular arc. In short, the shield 1 may be provided in a cylindrical structure in which one side of the peripheral wall is axially broken, and the opening end thereof forms an insertion opening.

The utility model also provides an electronic product, including current coil 01 to and the coil protector of aforementioned electronic product, wherein, current coil 01 installs inside protection casing 1, offsets with the inner wall of protection casing 1, and protruding muscle 2 corresponds the cartridge in current coil 01's circle clearance, offsets with both sides circle coil section 011.

The utility model discloses the electronic product includes the coil protector of aforementioned electronic product, therefore protection casing 1 plays the effect of location, makes protruding muscle 2 can be in the mounted position steadily, and protruding muscle 2 separates two adjacent circle of coil sections 011, even produce suction between circle of coil sections 011, because the restriction effect of protruding muscle 2, circle of coil sections 011 can not take place the distortion, avoids coil insulation to take place destruction, thereby avoids the emergence of situations such as coil short circuit burnout, improves the security performance; meanwhile, the protection device is simple in structure, convenient to install, low in cost and high in practicability.
