Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic coils, and in particular to a winding structure of a spot-welded frame. Background Technology
[0002] The electromagnetic coil in the electronic expansion valve is the power source that controls the valve body rotor. Enamelled wire is wound around the coil's skeleton structure, and the enamelled wire connects to a pin located on the skeleton structure. Specifically, the skeleton structure includes a fixed body and a terminal insertion structure. The enamelled wire is wound around the fixed body, and the pin is located on the terminal insertion structure. A portion of the enamelled wire extends from the fixed body to the pin for winding and connection.
[0003] Currently, the starting end of the enameled wire is first wound around the pin and attached to the end face of the bobbin. Then the winding machine spindle rotates at high speed to wind the wire. However, since there is no lead groove at the starting end, the enameled wire rubs against each other during the winding process. As a result, the enameled wire may break or be crushed after winding, which reduces the life of the coil and causes product failure. Utility Model Content

[0016] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0017] It should be noted that all directional indicators in this utility model embodiment, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0018] Furthermore, in addition to indicating orientation or positional relationship, the aforementioned terms may also be used to indicate other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. For those skilled in the art, the specific meaning of these terms in this utility model can be understood according to the specific circumstances.
[0019] Furthermore, the terms "installation," "setting," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral structures; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts. The connection methods described herein are existing technologies without any modifications and are common knowledge to those skilled in the art. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
