Abstract

The utility model relates to a kilowatt meter for preventing from charge evasions, which comprises a wiring terminal, and a terminal tail cover. The lower side of the terminal tail cover is fixedly provided with a transparent cover which is covered at the outside of the wiring terminal. The contact condition of a power line and the wiring terminal can be observed from the appearance of a kilowatt meter by the utility model, hidden troubles are avoided, the beautiful integral appearance can be reserved, and the utility model has the effects of preventing the faudulent use of electricity.

Description

Power-steeling preventing electric meter

The utility model belongs to watt-hour meter.

The electric power incoming line of known watt-hour meter is exposed to the outside, this causes opportunity to electricity filching person, in order to prevent stealing, the applicant improves former watt-hour meter, the afterbody lengthening of end tail-hood, electric power incoming line is all covered, this way has played certain effect to preventing stealing, but because the end tail-hood of lengthening is a non-transparent material, so can't observe the wiring situation, if will cause the contact site heating when power lead and the loose contact of watt-hour meter connection terminal, therefore this watt-hour meter exists the hidden danger of causing danger.

The purpose of this utility model then provides a kind of watt-hour meter inlet wire position that can prevent and the possibility of stealing occurs, can observe the power-steeling preventing electric meter of connection terminal place wiring situation again.

The technical scheme that is adopted is in order to achieve the above object:

This power-steeling preventing electric meter comprises connection terminal, and the end tail-hood is fixed with translucent cover in the bottom of watt-hour meter terminal tail-hood, and translucent cover covers on the outside of connection terminal.

The grab that becomes one with translucent cover is arranged on the inwall of the left and right side of translucent cover, and grab is installed on the projection of back plate face.

There are last bead and hook in the translucent cover upper end, and the end tail-hood has groove and hanging groove on the lower surface, and the bead on the translucent cover is contained in the groove, links up with in the hanging groove of packing into and with its extension to lump together.

This translucent cover is made with fire proofing.

This watt-hour meter has a translucent cover, therefore just can observe the situation that contacts of power lead and connection terminal from appearance, avoid hidden danger, and had good interlocking to make this watt-hour meter both keep the attractive in appearance of whole appearance between this cover and the end tail-hood, reached anti-electricity-theft purpose again.

Be described further below in conjunction with drawings and Examples:

Embodiment 1:

The bottom of known watt-hour meter 1 is end tail-hood 2, the translucent cover 3 that end tail-hood 2 following useful anti-fire proofings are done, translucent cover 3 covers on the outside of connection terminal 12, the grab 4 that becomes one with translucent cover 3 is arranged on the left surface of translucent cover 3 and the inwall of right flank, back plate face 1 ' the downward extended spot of watt-hour meter 1 has the projection 5 that is complementary with grab 4, projection 5 is installed in the grab 4 during assembling, and projection 5 is tightened by grab 4, translucent cover 3 has the crimping plate 6 that is connected as a single entity with translucent cover 3 with end tail-hood 2 contact positions, crimping plate 6 is pressed under the inner plane of end tail-hood 2 after this watt-hour meter assembles, and the hole that joint bolt 11 is passed is arranged on the crimping plate 6.Joint bolt makes

translucent cover

3 and 2 assemblings of end tail-hood firmly, is equipped with on the end tail-hood 2 to make itself and the fastening clamp-screw 7 of watt-hour meter, and thief-proof electrically more firm for making this watt-hour meter, clamp-screw 7 is answered lead sealing.Translucent cover 3 lower surfaces are jagged 8 by the rear wall place, are convenient to lead and pass through.

Embodiment 2:

Provided the another kind of mode that translucent cover connects with known watt-hour meter in the present embodiment, outer bead 9 and hook 10 are arranged on the translucent cover 3, the end tail-hood has groove 9a and hanging groove 10a on 2 lower surfaces, when translucent cover 3 connects with former watt-hour meter, be that the bead 9 of translucent cover 3 is inserted respectively in groove 9a and the hanging groove 10a with hook 10, bead 9 joint portion intensity is increased both, and hook is hung with hanging groove and lumped together.Also positioning element can be set on translucent cover and the end tail-hood 2, so that the location is more accurate.

Translucent cover can be more convenient when opening the lead sealing screw takes off for watt-hour meter in the foregoing description, if the therefore narrow space of dress table can according to circumstances be taken off translucent cover under electric industry staff's supervision, uses as existing watt-hour meter.

Embodiment 3:

Hold tail-hood 2 lower ends that the flange of downward extension is arranged in the present embodiment, the transparent flange that extends upwardly from inside surface that is covered with all has corresponding hole, position on two flanges, and translucent cover is packed on the watt-hour meter it by the joint bolt in the load hole 11.

The material of translucent cover should adopt the fire-retardant organic material of energy or also can adopt clear glass according to fit in the utility model, and translucent cover also can be made into partially transparent, the opaque form of part.
