Fastening type meter shell for electric energy meter

Abstract

The invention belongs to the technical field of meter shell devices of a unidirectional intelligent electric energy meter and relates to a fastening type meter shell for an electric energy meter. According to the fastening meter shell for the electric energy meter, a first spring is fixedly arranged on a programming key; the programming key is fixedly arranged in a programming key hole in an upper shell of the electric energy meter; a second spring is fixedly arranged on a rotator key; the rotator key is arranged in a rotator key hole in the upper shell of the electric energy meter; the upper surfaces of the programming key and the rotator key are flush with the upper shell of the electric energy meter; the upper shell of the electric energy meter is fixedly arranged to an assembly of an original electric energy meter seat; a first touch switch and a second touch switch are fixed on a circuit board; and gaps being 0.5mm are respectively formed between the first touch switch and the rotator key and between the second touch switche and the programming key. When the meter shell for the electric energy meter is in batch production, the production efficiency is obviously improved, the number of assembling accessories is reduced, the process personnel is reduced, the operating risk is reduced, the product quality and the production efficiency are improved, the cost is saved, and the production environment is environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of one-way intelligent electric energy meter casing devices, and relates to a batch production assembly for improving production efficiency, improving product quality and precision, and reducing product costs. snap-on case. Background technique: [0002] At present, the case of the electric energy meter commonly used in daily electricity occasions generally uses a collar to fix the buttons to close the upper and lower covers. This collar structure has complex processes in production and assembly, many production links, and low production efficiency. After the upper and lower covers are assembled, the precision is not high, and the safety is not strong. Especially in high-power occasions, the temperature inside the meter rises, which is prone to safety hazards; With a production capacity of 20,000 pieces per day, 3-4 people need to install the collar on the case production line; second, it is difficult to i...

[0002] At present, the case of the electric energy meter commonly used in daily electricity occasions generally uses a collar to fix the buttons to close the upper and lower covers. This collar structure has complex processes in production and assembly, many production links, and low production efficiency. After the upper and lower covers are assembled, the precision is not high, and the safety is not strong. Especially in high-power occasions, the temperature inside the meter rises, which is prone to safety hazards; With a production capacity of 20,000 pieces per day, 3-4 people need to install the collar on the case production line; second, it is difficult to install the collar. The operator first needs to pick up the collar and install it on the bottom of the button with his thumb, and then use The thumb and forefinger push the collar into the slot of the button. The production of tens of thousands of pieces per day makes the operator's fingers often worn out; third, if the operator does not push the collar into the slot of the button, it will cause The button falls during use; the fourth is because the collar is fixed on the button, and the collar is made of soft PE material, which has a certain degree of elasticity, so there will be a certain height error in the size of the reset button after each operation; Ring is now each cost 0.017 yuan, each set of watch case with 2 collars, the cost is higher, especially the material cost is higher; therefore, it is very difficult to find a case structure of an electric energy meter with a novel structure, easy assembly and low cost. Has application prospects
