Abstract
A coil device of an electronic expansion valve comprises a shell made of plastic materials, a coil framework, an enameled wire arranged on the coil framework, a stator shell and a positioning piece, wherein a positioning hole and fixing columns positioned on two sides of the positioning hole are formed in the end face of the opening end of the shell; the arc-shaped seat plate is attached to the end face of the shell, the positioning protrusions are embedded into the positioning holes and are in contact fit with the stator shell, and the fixing columns are fixed with the fixing holes. The setting of fixed post on the shell and setting element adopt such shape, and the setting element is fixed firmly with the shell, and intensity is big, protects the enameled wire effectively.
Description
Technical Field
The utility model relates to an electronic expansion valve, in particular to a coil device of an electronic expansion valve.
Background
At present, in the prior art, a coil device of an electronic expansion valve includes a housing made of a plastic material, a coil frame, an enameled wire arranged on the coil frame, a stator housing, and a positioning member, wherein the positioning member is connected with an opening end of the housing in a snap-fit manner. There are problems in that: the positioning piece and the shell are not fixed stably enough, the strength is small, and the coil can be damaged when the positioning piece bears an electric signal of instantaneous high pressure or ultrahigh pressure.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is: the coil device of the electronic expansion valve has the characteristic that the positioning piece and the shell are firmly fixed.
The utility model is realized by the following steps: the utility model provides a coil device of electronic expansion valve, includes shell, coil skeleton that plastic materials made, establishes enameled wire, stator housing and setting element on coil skeleton, its characterized in that: the end surface of the opening end of the shell is provided with a positioning hole and fixing columns positioned at the two sides of the positioning hole,
the positioning piece comprises an arc-shaped seat plate and a right-angle connecting plate, and the arc-shaped seat plate is provided with a positioning bulge and two fixing holes;
the arc-shaped seat plate is attached to the end face of the shell, the positioning protrusions are embedded into the positioning holes and are in contact fit with the stator shell, and the fixing columns are fixed with the fixing holes.
The coil device of the electronic expansion valve is characterized in that: the fixing column, the positioning hole and the shell are integrally formed;
the free end of the fixing column penetrates through the fixing hole, the free end of the fixing column forms a fixing head through hot-melt welding, and the fixing head is attached to the arc-shaped seat plate.
According to the coil device of the electronic expansion valve, the fixing column on the shell and the positioning piece are in the shape, the positioning piece and the shell are firmly fixed, the strength is high, and the enameled wire is effectively protected.

Fig. 3 is an exploded perspective view of the present invention.
Fig. 4 is a perspective view of the positioning member of the present invention.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, a coil device of an electronic expansion valve includes a housing 1 made of a plastic material, a bobbin 2, an enameled wire 3 disposed on the bobbin, a stator housing 4, and a positioning member 5;
a positioning hole 11 and fixing columns 12 positioned at two sides of the positioning hole are arranged on the end surface of the opening end of the shell 1,
the positioning piece 5 comprises a circular arc-shaped seat plate 51 and a right-angle connecting plate 52, and the circular arc-shaped seat plate 51 is provided with a positioning bulge 511 and two fixing holes 512;
the arc-shaped seat plate 51 is attached to the end face of the housing 1, the positioning protrusion 511 is embedded in the positioning hole 11 and is in contact fit with the stator housing, the fixing column 12 is fixed to the fixing hole 512, and the positioning element 5 is used for grounding. After the grounding device is installed with the valve body, the enameled wire is reliably grounded, and the damage of the coil caused by the instant high-voltage or ultrahigh-voltage electric signal borne by the product can be ensured.
The fixing column 12, the positioning hole 11 and the shell 1 are integrally formed;
the hanging end of the fixing column 12 passes through the fixing hole 512, the hanging end of the fixing column 12 forms a fixing head 121 through hot melt welding, and the fixing head 121 is attached to the arc-shaped seat plate 51.
What has been described above is merely a preferred embodiment of the present invention. It should be noted that a person skilled in the art could make several modifications and variations without departing from the principle of the present invention, which should also be regarded as the protection scope of the present invention.
