Circular internal-expansion type spring, is arranged at accordingly in described plug, is positioned at and is within the length of each described sheet metal place.
The electric energy meter attachment plug of above-mentioned use internal-expansion type spring, described sheet metal is more than 2 and 2, often has microspur interval between sheet metal described in adjacent two.
The electric energy meter attachment plug of above-mentioned use internal-expansion type spring, the upper end of each described sheet metal is all formed with a transition face.
The electric energy meter attachment plug of above-mentioned use internal-expansion type spring, the tangent plane that the transition face at each described sheet metal top is arc surface or tilts to the axial line of tubular structure.
The electric energy meter attachment plug of above-mentioned use internal-expansion type spring, described plug processes by conducting electricity good metal pipe material, and some sheet metals with microspur interval are processed on the top of metal pipe material, and bottom is processed as the electrical connection terminal of U-shaped structure.
The beneficial effects of the utility model are:
(1) connection terminal of plug of the present utility model direct grafting electric energy meter is made when installing, thus fundamentally change existing screw crimping mode, drastically increase in-site installation efficiency, the efficiency of the manufacturing and gauge check link can also be improved;
(2) plug of the present utility model is the tubular structure be made up of 2 and above sheet metal, after being in place, each sheet metal all contacts with connection terminal, coordinate its inner circular internal-expansion type spring arranged, after making each plug access connection terminal, suffer oppression in circular internal-expansion type spring and be out of shape and produce elastic potential energy, this elastic potential energy makes sheet metal and connection terminal fully contact and realizes being electrically connected, further ensure the connection terminal that plug can not depart from electric energy meter, ensure that installation quality.

Embodiment
The following description and drawings illustrate specific embodiments of the present utility model fully, to enable those skilled in the art to put into practice them.Embodiment only represents possible change.Unless explicitly requested, otherwise independent parts and function are optional, and the order of operation can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.The scope of embodiment of the present utility model comprises the gamut of claims, and all obtainable equivalent of claims.In this article, these embodiments of the present utility model can be represented with term " utility model " individually or always, this is only used to conveniently, and if in fact disclose the utility model more than, be not the scope that automatically will limit this application be any single utility model or utility model design.
As shown in Figures 1 to 4, be schematic diagram of the present utility model, the electric energy meter attachment plug of use internal-expansion type spring described in the utility model, its circular internal-expansion type spring 4 mainly including plug 1 and arrange in this plug 1.
The upper end of described plug 1 is made up of some sheet metals 101, for being connected with the connection terminal of electric energy meter, lower end is electrical connection terminal 5, for the wire crimped or spiral shell dress is electrically connected, make connection box of electric energy meter terminal can realize being electrically connected with outside, described plug 1 is processed by the good metal pipe material of conduction in the present embodiment, and the upper end of metal pipe material is processed as some sheet metals with microspur interval, and lower end is then processed as the electrical connection terminal of U-shaped structure.
The number of the sheet metal 101 of described plug 1 can be set according to concrete situation, be generally more than 2 and 2 (at least 2), and described circular internal-expansion type spring 4 is arranged at the top of described plug 1, its position is within the length range at described sheet metal 101 place, be preferably in top 102 inwall of described sheet metal 101, the compressible described circular internal-expansion type spring 4 when grafting also makes it to have elastic potential energy, to produce a kind of outer extruding trend to each described sheet metal 101.
Between above-mentioned every two adjacent sheet metals 101, there is microspur interval 2, when the plug 1 making to be formed by sheet metal is plugged to connection terminal, each sheet metal 101 can along the radially-inwardly contraction of tubular structure, simultaneously in grafting process, microspur interval 2 between two adjacent sheet metals 101 reduces gradually, and namely each sheet metal 101 of plug 1 has micro-deformation to access the connection terminal of electric energy meter with adapting in grafting process.
In grafting process, circular internal-expansion type spring 4 in described plug 1 is compressed and is stored the elastic potential energy having compression, after each described plug 1 all accesses the connection terminal of electric energy meter, the elastic potential energy that circular internal-expansion type spring 4 has makes again each sheet metal 101 of each plug 1 expand outwardly, and makes the connection terminal wringing fit of each sheet metal 101 and electric energy meter.
During concrete use, the top 102 of each sheet metal 101 of described plug 1 is all formed with a transition face 103, the tangent plane that the transition face 103 of each described sheet metal 101 can be arc surface or tilts to the axial line of tubular structure, installation process only needs the connection terminal of direct for each plug grafting electric energy meter, expanded outwardly the wringing fit between each sheet metal 101 and connection terminal (button seated connection terminal) making each plug 1 by each circular internal-expansion type spring 4 in plug after installation, also the external diameter of plug 1 can be made slightly larger than the internal diameter of connection box of electric energy meter terminal, coordinate transition face 103, while conveniently making plug 1 grafting enter connection box of electric energy meter terminal, more can realize the wringing fit between connection terminal.
Above-described embodiment is only for clearly illustrating that the utility model creates example, and the restriction not to the utility model embodiment.In order to the syntagmatic of each parts is clearly described, carry out usually describing around its function to various illustrative parts and annexation thereof above, combination as this parts realizes which kind of function, the design constraint depending on specific application and apply whole device.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All within spirit of the present utility model and principle any apparent change of extending out or variation be still among the protection domain of this claim.
