The plug has the advantages that contact pressure between the binding post and the connecting plate is enhanced to guarantee reliable contact between the binding post and the connecting plate, so that the plugging-unplugging type electric meter can be firmly inserted onto a meter base of an electric meter cabinet to guarantee metering accuracy of the electric meter.
Description
Technical field
The present invention relates to a kind of plug that is used for the plug-in ammeter in intelligent grid field.
Background technology
Ammeter is a ustomer premises access equipment important on the supply network, and whether the metering of ammeter is accurate, and the size of current that can bear of ammeter, for the safety of electrical network significant impact is arranged.At present, all be to adopt the mode of wiring to be fixedly connected between the table base of ammeter and ammeter box.Adopt the fixing ammeter of table base of this mode of connection and ammeter box to become the Wiring type ammeter.The maximum defective of Wiring type ammeter is: its electric current that can bear is little, can not satisfy the demand of resident's daily life electricity consumption.The plug-in ammeter replaces the Wiring type ammeter day by day at present, because the electric current that the plug-in ammeter can bear is much larger than the Wiring type ammeter.But because the grafting between plug-in ammeter and the table base is not very firm, this will cause the inaccurate of ammeter metering, influence the safe operation of electrical network.The not really firm major reason of grafting between the table base of plug-in ammeter and ammeter box is that the structural design that is used for the plug of plug-in ammeter is not quite reasonable.
Summary of the invention
The objective of the invention is provides a kind of plug that is used for the plug-in ammeter in order to overcome the deficiency of prior art, and it can be closely fixing with the table base of plug-in ammeter and ammeter box.
A kind of technical scheme that realizes above-mentioned purpose is: comprise binding post and brace; Said plug also comprises spring steel plate, and the inner surface of said spring steel plate is socketed on the bottom surface of said binding post, and the inner surface of said brace is socketed on the outer surface of said spring steel plate.
Further, the surface of said binding post, the surface of said spring steel plate and the inner surface of said brace all are provided with zinc-plated coating.
Further again, the thickness of said zinc-plated coating is 3 to 6 microns.
Further, said binding post is processed by brass.
Further, said spring steel plate is processed by steel plate.
Further, said brace is processed by the beryllium-bronze plate.
Further, the bottom surface of said binding post is a cambered surface.
Adopted a kind of technical scheme that is used for the plug of plug-in ammeter of the present invention, i.e. the technical scheme of socket spring steel plate between said binding post and said brace.Its technique effect is: strengthened the contact pressure between said binding post and the said brace, guaranteed reliable contact the between said binding post and the said brace, thereby guaranteed that the plug-in ammeter is plugged on the said table base of said ammeter box securely.Guarantee the accurate measurement of ammeter.

Embodiment
See also Fig. 1 to Fig. 4,, pass through embodiment particularly below, and combine accompanying drawing at length to explain in order to understand technical scheme of the present invention better:
A kind of plug that is used for the plug-in ammeter of the present invention; Comprise binding post 1, brace 3 and spring steel plate 2; The inner surface of said spring steel plate 2 is socketed on the bottom surface 11 of said binding post 1, and the inner surface 31 of said brace 3 is socketed on the outer surface 21 of said spring steel plate 2.
The purpose of design is like this: through adding said spring steel plate 2 to strengthen the contact pressure between said binding post 1 and the brace 3; Guarantee reliable contact the between said binding post 1 and the said brace 3, thereby guarantee that the plug-in ammeter is plugged on the said table base of said ammeter box securely.Guarantee the accurate measurement of ammeter.
In the present embodiment, the bottom surface 11 of the said binding post 1 on a kind of plug that is used for the plug-in ammeter of the present invention, the outer surface 21 of the inner surface of said spring steel plate 2, said spring steel plate 2, and the inner surface 31 of said brace 3 all is provided with zinc-plated coating.
It is technology commonly used on the low-voltage electrical apparatus connector that zinc-plated coating is set, and its reliability has obtained checking in long-term practice.Said zinc-plated coating has the little molten characteristic of big electric current; Littleization that produces owing to its little molten characteristic flows can guarantee the fine clearance between said binding post 1 bottom surface 11 and said spring steel plate 2 inner surfaces; And the fine clearance between said spring steel plate 2 outer surfaces 21 and said brace 3 inner surfaces 31 obtains filling; Thereby guarantee that the grafting between said binding post 1 and the said brace 3 is reliably, thereby guarantee that the plug-in ammeter is plugged on the said table base of said ammeter box securely.
The zinc-plated coating of the bottom surface 11 of said binding post 1; The said zinc-plated coating of stating spring steel plate 2 outer surfaces 21; The thickness of the zinc-plated coating of the inner surface 31 of the said zinc-plated coating of stating spring steel plate 2 outer surfaces 21 and said brace 3 is 3 to 6 microns; Because the zinc-plated coating of thickness can not influence the normal plug of said binding post 1 in the contact reliability of guaranteeing between said binding post 1 and the said brace 3 like this.
In the present embodiment; A kind of bottom surface 11 that is used for the binding post 1 of plug-in ammeter of the present invention is cambered surface; The purpose of design is like this: can increase the contact area between said binding post 1 and the said spring steel plate 2; Increase said spring steel plate 2 self elasticity, simultaneously operating personnel when the said plug of plug, the feel that has stronger plug to put in place.
In the present embodiment, said binding post 1 is processed by brass, and said brass is low-voltage electrical apparatus binding post material commonly used.The model of said brass is HBP59-1.
In the present embodiment, said spring steel plate 2 is processed by corrosion resistant plate, and design is the consideration from cost like this.The thickness of said corrosion resistant plate is 0.8cm.
In the present embodiment, said brace 3 is processed by the beryllium-bronze plate, and the thickness of said beryllium-bronze plate is 1cm, beryllium-bronze consist of ZCuBe0.5Co; Beryllium-bronze has high conduction, heat conductivility; High strength and high rigidity; Good resistance to wear, excellent high-temperature oxidative resistance and decay resistance are mainly used in and require that high strength, high conduction, the connector of high-termal conductivity, contactor touch frame, electric iron is first-class.
In the present embodiment; Because said plug has adopted the structure of the dismounting of layering from top to bottom; Be between said binding post 1 and the said spring steel plate 2; And can distinguish independent dismounting between said spring steel plate 2 and the said brace 3, and make things convenient for the fault epi-position to change, do not influence other ammeter operate as normal during single epi-position dismounting.
In the present embodiment; The radius of curvature R 1 of said spring steel plate 2 side outer surfaces 21 and the radius of curvature of said brace inner surface 31 equate; Be 11cm; Can further guarantee the firm grafting between said binding post 1 and the said brace 3 like this, thereby guarantee that the plug-in ammeter is plugged on the said table base of said ammeter box securely.
In the present embodiment, the width a of said brace inner surface 31 bottoms is 5cm.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention; As long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
