Description
Technical Field
The utility model relates to the technical field of electric machine, specifically a stable form insulating skeleton and motor thereof.
Background
The stator bobbin generally includes a coil bobbin for winding a wire and a terminal bobbin for mounting a conductive terminal. In general, the stator bobbin is usually one molded integral piece, that is, the coil bobbin and the terminal bobbin are integrally formed by molding. In the manufacturing process of the motor, an integrally formed stator frame is usually pressed into the stator, then a wire (e.g., an enameled wire) is wound on the coil frame to form a coil, then a lead end of the coil is pressed into a wire pressing groove on the terminal frame, and finally, a conductive terminal is pressed into a conductive terminal groove on the terminal frame so as to be electrically connected with the lead end of the coil.
The outer ring of the framework is provided with an outer retaining wall, and the inner ring of the framework is provided with an inner retaining wall for limiting the wound coil. The outer wall of the traditional inner retaining wall is arc-shaped, and when the coil is wound, pressure can be formed on the inner retaining wall. Because the coil is line contact with interior retaining wall outer wall, interior retaining wall can produce deformation to the inboard to form with the rotor and interfere, influence rotor normal operating.
SUMMERY OF THE UTILITY MODEL
For solving the technical problem in the background art, the utility model discloses an insulating skeleton of stable form and motor thereof.
The utility model provides an insulating skeleton of stable form, its outer lane is equipped with outer barricade, and the inner circle is equipped with rotational symmetry and interval arrangement's interior barricade, be equipped with coil winding portion between outer barricade and the interior barricade, interior barricade outer wall is equipped with straight terminal surface.
The arrangement of the flat end face increases the contact area of the inner retaining wall and the coil, so that the pressure intensity is reduced, the inner retaining wall is not easy to deform, and the normal operation of the rotor is ensured.
Further, the straight end faces are arranged in a rotational symmetry manner and are perpendicular to the coil winding portion. So set up, ensure coil and straight terminal surface laminating, straight terminal surface atress is more stable, the phenomenon of local atress can not appear.
Further, the bottom of the flat end face is flush with the coil winding part. So set up, the coil winding is more neat.
The strength of the inner retaining wall is affected if the straight end surface is too wide, so that the problem is further improved and solved, and particularly, arc-shaped surfaces are symmetrically arranged on two sides of the straight end surface.
Further, the width of the flat end surface is larger than the width of the coil wound portion. This ensures that the pressure from the wound coil is fully applied to the flat end face.
The utility model discloses still disclose a motor, which comprises a stator, the stator is equipped with an insulating skeleton of stable form for the winding coil. So set up, the motor operation is more stable, and life is longer.
Drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a top view of the present invention;
in the figure: 1. an outer retaining wall; 2. an internal retaining wall; 3. a flat end face; 4. a coil winding part.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The first embodiment is as follows:
as shown in fig. 1, the utility model discloses a stable insulating framework, wherein an outer retaining wall 1 is arranged on the outer ring of one end of the stable insulating framework, and inner retaining walls 2 which are rotationally symmetrical and arranged at intervals are arranged on the inner ring; the other end is provided with a plurality of pin pins which are rotationally symmetrical and are used for inserting the iron core to realize assembly and fixation.
A coil winding part 4 is connected between the outer retaining wall 1 and the inner retaining wall 2, and a straight end surface 3 is arranged on the outer wall of the inner retaining wall 2.
The straight end face 3 is arranged, so that the contact area between the inner retaining wall 2 and the coil is increased, the pressure intensity is reduced, the inner retaining wall 2 is not easy to deform, and the normal operation of the rotor is ensured.
The second embodiment:
compared with the first embodiment, the differences are as follows: as shown in fig. 2, the flat end surfaces 3 are arranged in rotational symmetry and perpendicular to the coil winding portion 4. So set up, ensure coil and the laminating of straight terminal surface 3, straight terminal surface 3 atress is more stable, the phenomenon of local atress can not appear.
Example three:
compared with the first embodiment, the differences are as follows: the bottom of the flat end face 3 is flush with the coil winding part 4. So set up, the coil winding is more neat.
Example four:
compared with the first embodiment, the differences are as follows: the two sides of the straight end surface 3 are provided with arc surfaces which are symmetrically arranged. So set up, avoid straight terminal surface 3 too wide, influence interior barricade 2's intensity.
Example five:
compared with the first embodiment, the differences are as follows: the width of the flat end surface 3 is larger than the width of the coil wound section 4. This ensures that the pressure created by the wound coil is fully applied to the flat end face 3.
Example six:
the utility model also discloses a motor, including the stator, the stator is equipped with embodiment one to five arbitrary stable form insulation framework for the winding coil. So set up, the motor operation is more stable, and life is longer.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the description, and must be determined according to the scope of the claims.
