Abstract

The utility model relates to a sealed wire which is formed by that a silk wire whose wire diameter is smaller than the wire diameter of a body silk wire is coiled on the body silk wire. When the sealed wire used, the wall of a lead-sealed button hole presses and casts an uneven body on the surface of the sealed wire deeply and firmly under the pressure function of the sealing, and thus the wall of the lead-sealed button hole and the sealed wire are formed into integration to be unable to be drawn, obtaining the purpose of the protection of electricity stealing.

Description

Sealed wire

The Sealed wire that the utility model provides a kind of seal to use belongs to the measuring apparatus annex.

In the power industry, as the verification and the installation of watt-hour meter, mutual inductor, the installation of metering cabinet, switch cubicle and conventional maintenance test etc. all need to seal up seal.Seal (or claim lead sealing) generally comprises that lead sealing is buckled and Sealed wire two parts.Adopt special-purpose seal pliers with its press seal by on the instrument and meter or machinery and equipment of sealing up.At present, Sealed wire adopts copper cash, iron wire, Chinese fiddle string and nylon yarn etc. more.Because the active line smooth surface, stressed back deflection is big, makes it might smash extraction from lead sealing behind press seal, behind the change instrument components and parts, again it is penetrated seal again and buckles, and finishes the forgery seal, constitutes stealing.

At the aforementioned deficiency that substitutes Sealed wire at present, the purpose of this utility model can not smashed play at seal after providing a kind of lead sealing, can not smashed the Sealed wire of extraction from seal.

Above-mentioned purpose of the present utility model realizes by following technical measures.

1, metallic main body silk thread is rolled into its surperficial lobed Sealed wire, screw-thread steel shape Sealed wire can be used as its representative;

2, metal matter main body silk thread is constituted the screw thread silk by extruding, if its shape is leading screw;

3, on the main body silk thread, curl the line footpath silk thread littler, form the screw thread silk thread than main body silk thread;

4, the main body silk is penetrated the plastic casing with protruding excipuliform outside surface, or the main body silk is made the bone line pressure be moulded shape.

Use Sealed wire provided by the utility model, lead sealing button hole wall dearly, the uneven body on the surface of die casting Sealed wire securely, makes it to become one and can't twitch under the pressure effect of sealing up, and reaches anti-electricity-theft purpose.

Accompanying drawing is a structural representation of the present utility model, below in conjunction with accompanying drawing, further narrates technical characterictic of the present utility model by most preferred embodiment.

Sealed wire is wrapped in main body line (1) by a line less outside line (2) in footpath and goes up formation.

Main body line (1) can employing and wire, copper wire line, plated film copper wire line, galvanized iron wire etc.Copper cash, galvanized iron wire are generally adopted in outside line (2).For minimum envelope table hole is watt-hour meter and the annex of 1.2mm, and copper wire adopts JB647-77 model TV high strength circle bare copper wire.Wherein: the main body line diameter is 0.31-0.33mm, and winding diameter is 0.23-0.27mm, and every centimeter is the 10-11 circle, and the overall wire footpath is less than 1mm.

Claims (2)

1, the Sealed wire used of a kind of seal is characterized in that Sealed wire is wrapped in main body line (1) by outside line (2) and goes up and constitute.

2, Sealed wire according to claim 1 is characterized in that the main body line diameter is 0.31-0.33mm, and winding diameter is 0.23-0.27mm, and every centimeter is the 10-11 circle.
