[0022] The current and voltage digital display meter and its housing of the present invention will be described in more detail below with reference to schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0023] For the sake of clarity, not all features of actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would clutter the present invention with unnecessary detail. It should be understood that in the development of any actual embodiment, numerous implementation details must be made to achieve the developer's specific goals, such as adapting from one embodiment to another to accommodate system or business constraints. Furthermore, it should be understood that such development work may be complex and time-consuming, but is nevertheless a routine undertaking for those skilled in the art.

[0024] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0025] like Figure 1 and Figure 2 As shown, the present invention provides a current and voltage digital display meter housing, comprising a main housing 2 and an ear button 201, wherein the ear button 201 is located outside the main housing 2;

[0026] Specifically, the ear button 201 is made of resin material, and is in the shape of an inclined ladder as a whole, with one end connected to the main shell 2 and the other end close to the upper cover 1.

[0027] Furthermore, the other end of the ear button 201 is an inclined surface with a plurality of grooves provided thereon.

[0028] Furthermore, a first flange 202 is provided at one end of the main housing 2. A first gap 208 is defined between the upper end of the ear clip 201 and the first flange 202, for securing the housing of the current and voltage digital display to an external device. The device panel 4 schematically illustrates only a portion of the external device; the remainder of the external device is not shown.

[0029] Furthermore, it also includes an upper cover 1 and a bottom cover 3, both of which are snap-fitted to the main housing 2. The upper cover 1 is made of a translucent resin material, with a slightly raised center and a convex edge on the edge.

[0030] Furthermore, a second protrusion 203 is provided at one end of the main shell 2 away from the first protrusion 202, and a triangular first slot 206 is provided inside the main shell 2. There is a second gap 209 between the first slot 206 and the second protrusion 203, and the second gap 209 is used to clamp the upper cover 1.

[0031] Therefore, when the upper cover 1 is installed, the entire upper cover 1 can be used as a display area, thereby having a larger display range.

[0032] Furthermore, a plurality of hollow square second card slots 207 are provided at the bottom of the main shell 2, and a plurality of clips 31 are provided on the bottom cover 3. It should be noted that the number of clips 31 here can be more than two, and four are schematically shown in the figure. The clip 31 is connected to the bottom cover 3 on only one side, and a protrusion is provided in the middle of the clip 31, which can clamp the second card slot 207 at the bottom of the main shell 2. The cooperation between the clip 31 and the second card slot 207 realizes the clamping connection between the bottom cover 3 and the main shell 2, providing a stable sealing effect.

[0033] Furthermore, an inverted U-shaped hollow opening is provided on the main shell 3, and a third flange 204 is provided inwardly at one end of the hollow opening, and a fourth flange 205 is provided inside the main shell 2. For example, the number of the third flange 204 and the fourth flange 205 are both 4. It can be understood that the number range here is 2 or more. Figure 5 As shown, there is a third gap 210 between the third protrusion 204 and the fourth protrusion 205 . These protrusions not only increase the structural strength of the housing, but also make the PCB board 5 more firmly fixed in the main housing 2 .

[0034] It should be noted that the ear clips 201 and the upper cover 1 are made of resin, which is selected for its lightness, durability and ease of processing. The use of resin also helps to reduce the weight of the entire housing.

[0035] Furthermore, a square opening is provided on one side of the main housing 2 for connecting a PCB interface or a data cable.

[0036] In a preferred embodiment, the installer can install the housing of the current and voltage digital display meter by following the steps below:

[0037] S1: Snap the translucent resin cover 1 upward from the bottom of the main housing 2. At this time, the edge of the cover 1 will be between the first slot 206 and the second protrusion 203.

[0038] S2: The PCB board is clamped upward from the bottom of the main shell 2. At this time, the PCB board 5 is clamped between the third flange 204 and the fourth flange 205 by squeezing the third flange 204 on the main shell 2, so that the PCB board is more stable in the main shell 2.

[0039] S3: Push the bottom cover 3 into the bottom of the main shell 2 , squeezing it to produce a slight deformation so that the middle protrusion of the buckle 31 is just locked in the second slot 207 of the main shell 2 .

[0040] S4: As Figure 3 As shown, the ear button 201 is squeezed by the machine panel 4 of the external device to produce a slight deformation, so that the first protrusion 202 of the main shell 2 and the ear button 201 are firmly stuck on the machine panel 4 of the external device.

[0041] In summary, the current and voltage digital display provided in the embodiments of the present invention is characterized by including any of the above-described current and voltage digital display housings. This digital display design meets the requirements for electrical measurement equipment in modern industrial and commercial environments, featuring a sturdy structure, attractive appearance, and ease of operation.

[0042] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, makes any equivalent substitution, modification, or other variation to the technical solution and technical content disclosed herein shall be deemed to fall within the scope of the present invention and remain within the scope of protection of the present invention.
