Description

Injection molding motor stator and motor thereof

Technical Field

The utility model relates to the technical field of motors, in particular to an injection molding motor stator and a motor thereof.

Background

The existing injection molding stepping motor comprises an injection molding stator assembly, wherein the injection molding stator assembly comprises a stator core, a front framework, a rear framework, a stator winding, a front inner lining ring, a rear inner lining ring and a mounting bracket, and the injection molding stator assembly is formed by injection molding through a mold.

And the copper wire on the stator winding penetrates out of the wire outlet. The conventional stator outlet end surface is flush, so that a sharp notch is formed, and cutting injury is caused to a lead.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems in the background art, the utility model discloses an injection molding motor stator and a motor thereof.

The utility model provides an injection molding motor stator which comprises a body, wherein the body is provided with a plurality of wire outlets for copper wires to penetrate out, the wire outlets are provided with convex blocks protruding outwards, and the convex blocks have elasticity.

The lug isolates the copper wire from the edge of the wire outlet, so that the copper wire is prevented from being damaged by cutting; and when the copper wire is bent, the convex block is deformed under the action of elasticity, so that the copper wire is protected from being damaged.

To specifically describe the material of the bump, in this embodiment, the bump is made of rubber.

Further, the lug is in a necking shape. So set up, the lug is changeed and is produced deformation to make the copper line obtain better protection.

When the thickness of the bump is too large, the cost is high, and when the thickness of the bump is too small, the copper wire cannot be well protected, so that the problem is further improved and solved, and particularly, the protruding thickness of the bump is 1/3-1/2 of the diameter of the copper wire.

To illustrate the concrete necking structure of the bump, in the present embodiment, the side surface inclination angle of the bump is 45 °.

The body is thin, so that the wire outlet is easy to deform and even break when stressed, the problem is further improved and solved, and particularly, the outer wall of the body is further provided with a convex plate, and the wire outlet is arranged on the convex plate. The convex plate increases the thickness of the body, thereby improving the strength of the wire outlet.

The utility model also provides a motor which comprises the injection molding motor stator. So set up, the motor performance is more stable, and life is longer.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 2, the utility model discloses an injection molding motor stator, which comprises a body 1, wherein the body 1 is square, and the bottom of the body 1 is provided with four uniformly distributed mounting holes for fixing the body 1. The body 1 is equipped with a plurality of outlets for copper line 3 wears out, and the outlet is equipped with outside bellied lug 2, and the lug 2 material is rubber, has elasticity.

The lug 2 isolates the copper wire 3 from the edge of the wire outlet, thereby preventing the copper wire 3 from being damaged by cutting; and when the copper wire 3 is bent, the bump 2 is deformed under the action of elasticity, so that the copper wire 3 is protected from being damaged.

Example two:

compared with the first embodiment, the differences are as follows: the protruding thickness of the bump 2 is set to 1/3 of the diameter of the copper wire 3. The excessive thickness of the bump 2 is avoided, and the cost is increased; the bump 2 has too small thickness to provide a good protection effect for the copper wire 3.

Example three:

compared with the two examples, the difference is that: the protruding thickness of the bump 2 is set to 1/2 of the diameter of the copper wire 3.

Example four:

compared with the first embodiment, the differences are as follows: as shown in fig. 3, the protrusion 2 is in a tapered shape, and the side surface thereof is inclined at an angle of 45 °. So set up, lug 2 is changeed and is produced deformation to make copper line 3 obtain better protection.

Example five:

compared with the first embodiment, the differences are as follows: the outer wall of the body 1 is also provided with a convex plate, and the wire outlet is arranged on the convex plate. The convex plate increases the thickness of the body 1, so that the strength of the wire outlet is improved, and the deformation and even breakage of the wire outlet caused by stress are avoided.

Example six:

the utility model also discloses a motor which comprises any one of the five injection molding motor stators according to the embodiment. So set up, the motor performance is more stable, and life is longer.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
