Problems solved by technology

[0002] With the transformation of the national grid, the smart grid is vigorously promoted, and the consumption of electric energy meters, electric boxes and air switches is greatly increased. At present, the connection of electric energy meters and air switches in the meter boxes is mostly connected by screws and wires. The more connecting wires are, the wiring of the internal connecting wires is complicated, and it is easy to connect the wrong wires. The labor intensity of the wiring workers is high and the efficiency is low. Moreover, when tightening the screws, if they are not tightened enough or forgot to tighten them, it will cause serious consequences due to poor contact.

Embodiment 1

[0047] like Figure 11 As shown, the inner elastic part 14 includes an expansion part 141, and the expansion part 141 is against the inner surface of the front part of the elastic tensioning part 112. The expansion part 141 is trumpet-shaped, which includes a small-diameter end 142 and a large-diameter end 143. The small-diameter end 142 of the expansion part 141 is integrally connected to a connecting piece 144. The connecting piece 144 can be a hollow straight cylinder, a round Ring or disc, the expansion part 141 of the inner elastic part 14 is in the same direction as the front part of the elastic tensioning part 112. When the connector body 1 is inserted into the terminal insertion hole 31, the elastic tensioning part 112 The front part and the expansion part 141 of the inner elastic part 14 are pressed together to generate radially outward elastic force at the same time. The metal inner elastic part 14 with good elasticity is selected, and the radially outward elastic fo...

Embodiment 2

[0049] like Figure 12 As shown, the inner elastic part 14 includes an expansion part 141, and the expansion part 141 is against the inner surface of the front part of the elastic tensioning part 112. distribution, the expansion part 141 is trumpet-shaped, and it includes a small-diameter end 142 and a large-diameter end 143. The two expansion parts 141 with the same structure are connected by a connecting piece 144 to form a whole. Due to the elasticity The front end of the tensioning member 112 is folded inward, and the front part is expanded, so there are two points with the same inner diameter inside the elastic tensioning member 112, and the largest diameter end of the inner elastic member 14 is placed at the two points. between points.

Embodiment 3

[0051] like Figure 13 As shown, the inner elastic part 14 includes an expansion part 141, and the expansion part 141 is against the inner surface of the front part of the elastic tensioning part 112. distribution, the expansion part 141 is trumpet-shaped, and it includes a small-diameter end 142 and a large-diameter end 143. The two expansion parts 141 with the same structure are connected to form a whole through their large-diameter ends 143, and their small-diameter ends 142 Connectors 144 are provided. The inner elastic member 14 is lantern-shaped, and the largest diameter end of the inner elastic member 14 can be placed at the largest diameter of the inner surface of the elastic tension member 112 .

Abstract

The invention relates to an internal spring type plug connector and an electric energy meter. The internal spring type plug connector comprises a plug connector body, which is sequentially composed of a plug unit, a limiting unit and a connecting unit, wherein the plug unit is an elastic expansion unit composed of a plurality of circumferentially arranged metal pieces with the front portions distributed at intervals and the root portions connected to the limiting unit; the front portion of the elastic expansion unit expands, the front end of the elastic expansion unit is folded inwards, and the inside of the elastic expansion unit is provided with a metal internal spring pieces for assisting the front portion of the elastic expansion unit to expand. The electric energy meter comprises the plug connector body, a meter support and an electric energy meter housing. The internal spring piece is made of alloy steel with excellent elastic performance, so that the elastic expansion unit can be free restriction of elasticity and can be made of metal with better conducting performance. Therefore, after the plug connector body is completely plugged into a plug hole of a wiring terminal, the elasticity of the front portion of the elastic expansion unit can be matched with that of the internal spring piece to ensure tight contact between the front portion of the elastic expansion unit and the inner wall of the plug hole of the wiring terminal, requirements on large plugging and high current can be met, and efficient power transmission can be achieved.

Description

technical field [0001] The invention relates to a metering box accessory, in particular to an inner elastic connector and an electric energy meter. Background technique [0002] With the transformation of the national grid, the smart grid is vigorously promoted, and the consumption of electric energy meters, electric boxes and air switches is greatly increased. At present, the connection of electric energy meters and air switches in the meter boxes is mostly connected by screws and wires. The more meter positions, The more connecting wires are, the wiring of the internal connecting wires is complex, and it is easy to connect the wrong wires. The labor intensity of the wiring workers is high and the efficiency is low. Moreover, when tightening the screws, if they are not tightened enough or forgotten to tighten, it will cause serious consequences due to poor contact. . SUMMARY OF THE INVENTION [0003] In order to overcome the disadvantages of the background technology, th...
