Description

Insulating skeleton convenient to wire winding back end of a thread cuts off and motor thereof

Technical Field

The utility model relates to the technical field of motors, in particular to an insulating framework convenient for cutting off a wire end after winding and a motor thereof.

Background

The stator bobbin generally includes a coil bobbin for winding a wire and a terminal bobbin for mounting a conductive terminal. Generally, the stator bobbin is generally 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.

After the copper wire is wound, the wire end needs to be cut off. Under the conventional condition, the wire end is cut off in the air, and the wound copper wire is easily pulled during cutting due to the high strength of the copper wire, so that the coil is deformed, the local distribution is uneven, and the performance of the motor is influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem in the background technology, the utility model discloses an insulating framework convenient for cutting off a thread end after winding and a motor thereof.

The utility model provides an insulating framework convenient for cutting off a coil end after winding.

When the end of a thread need cut off, support the copper line on the lug, the lug becomes the strong point that the copper line cut off, when the end of a thread cuts off, can not produce the displacement to can not drag winding copper line, can not influence the motor performance yet.

The lug is difficult to install due to the fact that copper wires need to be wound on the outer side of the framework, and therefore the lug is further improved and solved, and particularly the lug is located on the inner circle of the framework.

When the coil bypasses the framework to the lug, the length of the thread end is too long, so that the problem is further solved in an improved mode.

The inner ring of the framework is provided with a plurality of grooves, the U-shaped grooves are arranged on the grooves, and the convex blocks are positioned in the grooves. The arrangement of the groove reduces the height of the projection of the bump.

In order to explain the specific arrangement structure of the lug and the U-shaped groove, in the scheme, the lug is rectangular, and the width of the lug is larger than that of the U-shaped groove. The central line of the length direction of the convex block is collinear with the symmetrical line of the U-shaped groove.

The utility model also provides a motor which comprises a stator, wherein the stator is provided with an insulating framework which is convenient for cutting off the wire end after winding and is used for winding the coil. So set up, the motor performance is more stable.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a top view of the present invention;

FIG. 3 is a cross-sectional view of the present invention;

in the figure: 1. a framework; 2. a bump; 3. a U-shaped groove; 4. a groove; 11. a tube body; 12. and (6) winding the block.

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 figure 1, the utility model relates to an insulating framework convenient for cutting off a thread end after winding, which comprises a framework 1, wherein the framework 1 is provided with a tube body 11, and the outer wall of the tube body 11 is connected with a plurality of winding blocks 12 which are rotationally symmetrical and integrally formed and are used for winding copper wires.

The inner wall of the tube body 11 is provided with a plurality of projections 2 corresponding to the winding blocks 12,

when the end of a thread need cut off, support the copper line on lug 2, lug 2 becomes the strong point that the copper line cut off, when the end of a thread cuts off, can not produce the displacement to can not drag winding copper line, can not influence the motor performance yet.

Example two:

compared with the first embodiment, the differences are as follows: the tube body 11 is provided with a plurality of symmetrical U-shaped grooves 3, as shown in fig. 3, one end of the projection 2 is close to the bottom of the U-shaped groove 3, and the other end is far away from the U-shaped groove 3. The projection 2 is rectangular and has a width greater than that of the U-shaped groove 3. The central line of the lug 2 in the length direction is collinear with the symmetrical line of the U-shaped groove 3. The thread end firstly passes through the U-shaped groove 3 and then abuts against the convex block 2 to be cut, so that the thread end is prevented from bypassing the tube body 11 and causing overlong length.

Example three:

compared with the two examples, the difference is that: as shown in fig. 2, the inner ring of the framework 1 is provided with a plurality of grooves 4, the U-shaped groove 3 is arranged on the grooves 4, and the projection 2 is positioned in the groove 4. The arrangement of the groove 4 reduces the height of the projection of the bump 2. So set up, avoid lug 2 to bulge the body 11 inner wall too much, lead to pegging graft in the part installation difficulty of body 11 inner circle.

Example four:

the utility model also discloses a motor which comprises a stator, wherein the stator is provided with any one of the first embodiment, the second embodiment and the third embodiment, which is an insulating framework convenient for cutting off the end of a wire after winding and is used for winding a coil. So set up, the motor performance is more stable.

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.
