Description

Novel connection structure's coil and motor thereof

Technical Field

The utility model relates to the technical field of electric machine, specifically a novel connection structure's coil and motor thereof.

Background

An Electric machine (also known as "motor") refers to an electromagnetic device that converts or transmits Electric energy according to the law of electromagnetic induction.

The motor mainly comprises a stator, a rotor and other accessories. The most important component of the stator and rotor is the coil.

The motor coil is a ring-shaped wire winding and refers to an inductor. The insulated wire is wound one by one, the wires are mutually insulated, and the insulated tube can be hollow and also can contain an iron core or a magnetic powder core, namely an inductor for short. The inductor can be divided into a fixed inductor and a variable inductor, and the fixed inductor coil is called an inductor or a coil for short.

Conventional series connections between coils of an electric machine are typically made by wire butt welding, which not only is long and inefficient, but also is prone to risk of separation.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problems that the traditional motor coil series connection process is long in time and low in efficiency and is easy to cause disconnection are solved.

The utility model provides a coil with a novel connection structure, which comprises a coil body and a copper ring;

and the wire ends of the coil bodies connected in series are inserted into the copper rings and are fixed by resistance welding in a compression joint mode.

The setting of copper ring not only realizes that the coil body links to each other fast, is difficult for moreover breaking away, ensures the stability of motor operation.

The coil body is characterized in that the coil body is provided with a plurality of coil heads, the coil heads are connected with the coil bodies in a butt joint mode, and the coil bodies are connected with the coil bodies in a butt joint mode.

In order to realize the mass production of the copper ring, in the scheme, the copper ring is in a round tube shape in an initial state.

Furthermore, the wire ends penetrate through the copper ring. So set up, increased the superimposed area of end of a thread, joint strength is higher.

The utility model also provides a motor, include a novel connection structure's coil. So set up, the motor operation 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 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 and fig. 2, the utility model discloses a novel connection structure's coil, including coil body 1 and copper ring 2.

The coil is wound on the winding frame, thereby forming a coil. One end of the coil is led out of the copper bar and is set as a connected wire end.

As shown in fig. 3, the copper ring 2 is in a circular tube shape in the initial state, which facilitates mass production of the copper ring 2.

The wire end is inserted in the copper ring 2 and is fixed by resistance welding. As shown in fig. 4-6, the copper ring 2 is now flattened and engages the thread end.

The setting of copper ring 2 not only realizes that coil body 1 links to each other fast, is difficult for moreover breaking away, ensures the stability of motor operation.

Example two:

compared with the first embodiment, the differences are as follows: the wire ends of the coil body 1 are arranged in a superposition manner. The wire end of the conventional coil body 1 is inserted into the copper ring 2 in a butt joint mode, so that the connection strength is not high, and the technical problem is solved by the design.

Example three: the thread ends penetrate through the copper ring 2. So set up, increased the superimposed area of end of a thread, joint strength is higher.

Example four: the utility model discloses still disclose a motor, including embodiment one to three arbitrary novel connection structure's 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 specification, and must be determined according to the scope of the claims.
