Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a meter box that prevents ants from entering. Background Technology

[0002] An electricity meter box is a device used to store electricity meters. It is typically made of engineering plastics such as ABS, transparent polycarbonate (PC), DMC, and SMC, manufactured through injection molding and pressing processes. The main function of the meter box is to protect electrical equipment from external environmental influences and to provide a separate distribution room and meter room. It is usually designed with doors opening to the left and right for easy operation and maintenance. This design ensures the safe operation of the meters and electrical equipment while facilitating daily management and maintenance.

[0003] When the electricity meter is working outdoors, ants can enter the meter box through the gap between the silicone button and the meter box, and may eat the silicone button or other electronic components, causing damage to the meter. Therefore, a meter box that prevents ants from entering is needed to solve the above problem. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an electric meter box that prevents ants from entering. It is designed with a silicone button with a plastic button cap to seal the gap and prevent ants from entering the meter box.

[0005] This utility model embodiment is implemented as follows: an electric meter box that prevents ants from entering includes: a housing and a PCB board. The housing has an opening, and the PCB board is installed inside the housing; a bracket is installed on the PCB board, and a silicone button that passes through the opening in the housing is mounted on the bracket. The silicone button has a slot, and the bracket is used to maintain the stability of the silicone button. Pressing the silicone button can trigger the PCB board; a plastic button cap passes through the opening and fits into the slot of the silicone button. The plastic button cap can fit tightly against the inner wall of the housing to prevent ants from entering the housing through the gap in the opening.

[0006] Preferably, the height of the PCB board to the edge of the plastic button cap is slightly higher than the height of the PCB board to the inner surface of the housing.

[0007] Preferably, the height of the plastic button cap is slightly higher than the thickness of the housing and the stroke of the silicone button.

[0008] Preferably, the peripheral dimensions of the plastic keycap are slightly smaller than the size of the opening in the housing to ensure that the plastic keycap can pass through the opening.

[0009] Preferably, the height of the slot in the silicone button is slightly higher than the height of the plastic button cap; the radius (R) of the plastic button cap is slightly larger than the radius (R) of the silicone button.

[0010] The meter box that prevents ants from entering provided by this utility model can prevent ants from entering the meter box, effectively protecting the electronic components inside the meter box, extending the service life of the electronic components, and is highly practical.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figure 1 This utility model provides an electrical meter box that prevents ants from entering. The electrical meter box that prevents ants from entering includes:

[0021] The enclosure consists of a housing 1 and a PCB board 2. The housing 1 has an opening, and the PCB board 2 is installed inside the housing 1. A bracket 3 is mounted on the PCB board 2. A silicone button 4, which passes through the opening in the housing 1, is mounted on the bracket 3. The silicone button 4 has a slot. The bracket 3 is used to maintain the stability of the silicone button 4. Pressing the silicone button 4 can trigger the PCB board 2. A plastic button cap 5 passes through the opening and fits into the slot of the silicone button 4. The plastic button cap 5 can fit tightly against the inner wall of the housing 1 to prevent ants from entering the housing 1 through the gap in the opening.

[0022] When using the meter box that prevents ants from entering, pressing the plastic button cap 5 will press down the silicone button 4. The bracket 3 ensures the stability of the silicone button 4, thereby triggering the PCB board 2 to control the meter. The plastic button cap 5 can prevent ants from entering the housing 1, thus protecting the silicone button and other electronic components inside the housing 1 and extending the life of the meter.

[0023] like Figure 2 and Figure 3 As shown, in a preferred embodiment of this utility model, the height of the PCB board 2 to the stop edge of the plastic button cap 5 is slightly higher than the height of the PCB board 2 to the inner surface of the housing 1.

[0024] Specifically, to ensure a reliable seal between the plastic button cap 5 and the housing 1, the stop edge of the plastic button cap 5 should maintain a certain pre-pressure with the inside of the housing 1, such as... Figure 2 and Figure 3 As shown, the dimensional requirements are: under natural conditions, H1-H2 = 0.1~0.15mm, meaning the bottom of the silicone button 4 contacts the PCB board 2, and the height of the PCB board 2 from the stop edge is slightly higher than the height of the PCB board 2 from the inner surface of the housing 1. This ensures that when the plastic button cap 5 is installed into the housing 1, there will be a certain pre-pressure, causing the stop edge to fit tightly against the inner surface of the housing 1.

[0025] like Figure 4 As shown, in a preferred embodiment of this utility model, the height of the plastic button cap 5 is slightly higher than the thickness of the housing 1 and the pressing stroke of the silicone button 4.

[0026] Specifically, to ensure that the silicone button 4 can achieve smooth pressing function, the height of the silicone button cap 5 is designed as H = A + stroke (1.5mm) + 1.0mm, where A is the thickness of the shell 1 and H is the height from the stop edge of the plastic button cap 5 to the top.

[0027] like Figure 5 As shown, in a preferred embodiment of the present invention, the peripheral dimensions of the plastic keycap 5 are slightly smaller than the size of the opening in the housing 1 to ensure that the plastic keycap 5 can pass through the opening.

[0028] Specifically, the plastic button cap 5 should maintain a double-sided gap of 0.1 to 0.15 mm with the size of the housing 1, that is: B2-B1 = 0.1 to 0.15 mm, A2-A1 = 0.1 to 0.15 mm.

[0029] like Figure 6 As shown, in a preferred embodiment of this utility model, the height of the slot opened on the silicone button 4 is slightly higher than the height of the plastic button cap 5; the radius (R) of the plastic button cap 5 is slightly larger than the radius (R) of the silicone button 4.

[0030] Specifically, A2-A1 = 0.10mm, with A2 slightly higher than A1, ensuring reliable contact between the top of the silicone button 4 and the plastic button cap 5. Since the silicone button 4 and the plastic button cap 5 are in a static fit, the four corners of the mating parts of the silicone button 4 and the plastic button cap 5 are increased by R0.30~0.40mm to ensure smooth airflow during assembly. In a set of plastic button caps 5, one needs a blind spot, while the silicone button 4 does not require one.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
