Abstract
An anti-retraction terminal block of an intelligent electricity meter comprises a block body (1). The block body (1) is provided with a slot (2), and a voltage and current wiring terminal is inserted in the slot (2). The anti-retraction terminal block of the intelligent electricity meter is characterized in that a mounting hole (3) for access of a wire crimping screw screwed into a wire crimping screw hole is arranged at a position, corresponding to the wire crimping screw hole, on the voltage and current wiring terminal, and one end or two ends of the mounting hole (3) is an arc-shaped structure (4) matching with the wire crimping screw hole. The anti-retraction terminal block of the intelligent electricity meter can effectively prevent retraction of the wiring terminal while avoiding affecting a basic structure in normative requirements, meets production requirements, and improves safety of products.
Description
Technical field
The utility model relates to a kind of ammeter, and especially a kind of intelligent electric meter is used terminal base, and terminal base contracts in specifically a kind of intelligent electric meter is anti-.
Background technology
According to the intelligent construction plan of State Grid Corporation of China's electrical network, intelligent grid electricity consumption link comprises " power information acquisition system ", " two-way interaction marketing technology " etc. and builds and research project.Carrying out the electric energy meter of seeking unity of standard, possess certain function is one of gordian technique basis of carrying out these intelligent construction projects.
The substantive requirements of form such as environmental baseline, specification requirement, display requirement, surface structure, installation dimension, material and technology of in " intelligent electric energy meter series standard a surname of State Grid Corporation of China is passed through the material second fascicle form, function, safety standard interpretation of section ", having stipulated the single-phase intelligent electric energy meter.But, in the inner design of drain pan, specifically do not provide physical dimension, bring certain difficulty therefore for the making of electric energy meter, thereby influenced the production of electric energy meter.When adopting the crimping mode to carry out electric energy meter calibration, for the binding post that guarantees calibration equipment can keep excellent contact with energy meter terminal, require electric current and voltage terminal connections post when receiving the pressure of axial 60N, binding post does not contract in not answering; The auxiliary terminal post is when receiving the pressure of axial 10N, and binding post does not contract in not answering.And existing common end stroma screws in line ball in the binding post owing to the square mounting hole voltage supply line screw that adopts, and this structure its axially loaded when calibrating can not meet the demands, and is easy to contract in the stressed back, therefore, is necessary to improve.
Summary of the invention
The purpose of the utility model is to contract in the meeting when receiving axial calibrating pressure to existing binding post to cause contacting bad problem, designs a kind of intelligent electric meter terminal base that contracts in anti-.
The technical scheme of the utility model is:
Terminal base contracts in a kind of intelligent electric meter is anti-; Comprise pedestal 1; This pedestal 1 is provided with the jack 2 of plug-in mounting electric current and voltage binding post; It is characterized in that with the electric current and voltage binding post on line ball screw opposite position place be provided with the mounting hole 3 of the line pressing bolt turnover that supply to screw in the line ball screw, the one or both ends of described mounting hole 3 are the arcuate structure 4 that line pressing bolt matches.
The lower end of said line pressing bolt offsets with the lead that inserts in the electric current and voltage binding post, and the upper end of line pressing bolt exceeds the upper surface of mounting hole 3, and the cambered surface of the double-screw bolt face of line pressing bolt and said arcuate structure 4 is tangent.
Said mounting hole 3 is the waist pore structure.
The beneficial effect of the utility model:
The utility model can effectively prevent the phenomenon that contracts in the connection terminal in the basic structure that does not influence standard-required, satisfied the production demand, has improved security of products.
The utility model is simple in structure, is easy to realize.
Description of drawings
Fig. 1 is the perspective view of the terminal base of the utility model.
Fig. 2 is the plan structure synoptic diagram of Fig. 1.
Fig. 3 is the A-A sectional structure synoptic diagram of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Shown in Fig. 1-3.
The terminal base that contracts in a kind of intelligent electric meter is anti-comprises pedestal 1, and this pedestal 1 is provided with the jack 2 of plug-in mounting electric current and voltage binding post; As shown in Figure 1; With the electric current and voltage binding post on line ball screw opposite position place be provided with the mounting hole 3 of the line pressing bolt turnover that supply to screw in the line ball screw, the one or both ends of described mounting hole 3 are the arcuate structure 4 that line pressing bolt matches, when two ends are arcuate structure; Mounting hole is the waist pore structure, and is as shown in Figure 2.The lower end of line pressing bolt offsets with the lead that inserts in the electric current and voltage binding post, and the upper end of line pressing bolt exceeds the upper surface of mounting hole 3, and the cambered surface of the double-screw bolt face of line pressing bolt and said arcuate structure 4 is tangent.When calibrating offseted with the binding post of binding post and the utility model, stressed and cambered surface mounting hole 3 of the line pressing bolt on the binding post offseted, and like Fig. 3, thereby prevented that binding post from contracting in moving because of receiving axial force.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
Claims (3)
1. terminal base contracts in an intelligent electric meter is prevented; Comprise pedestal (1); This pedestal (1) is provided with the jack (2) of plug-in mounting electric current and voltage binding post; It is characterized in that with the electric current and voltage binding post on line ball screw opposite position place be provided with the mounting hole (3) of the line pressing bolt turnover that supply to screw in the line ball screw, the one or both ends of described mounting hole (3) are the arcuate structure (4) that line pressing bolt matches.
2. terminal base according to claim 1; The lower end that it is characterized in that said line pressing bolt offsets with the lead that inserts in the electric current and voltage binding post; The upper end of line pressing bolt exceeds the upper surface of mounting hole (3), and the cambered surface of the double-screw bolt face of line pressing bolt and said arcuate structure (4) is tangent.
3. terminal base according to claim 1 is characterized in that said mounting hole (3) is the waist pore structure.
