Abstract

The utility model discloses a major loop contact box for drawers of a low-voltage complete set of equipment, which comprises a moving contact, a fixed contact, an insulating box, grooves, a fixing piece, a notch, and a lug. The major loop contact box for drawers of the low-voltage complete set of equipment is composed of a contact and the insulating box, wherein the contact is arranged in the insulating box, the grooves and a boss are respectively arranged on the contact and in the insulating box, the contact is clamped on the boss of the insulating box by the grooves and is fixed in the insulating box by the fixing piece, the contact is the moving contact or the fixed contact; the notch and the lug are arranged on the outside surface of the insulating box respectively, thus the notch of an insulating box and the lug of another insulating box can be mutually occluded and engaged together. The major loop contact box for drawers of a low-voltage complete set of equipment has the advantages of good universality, material saving, low manufacturing cost, good insulating property, heat dissipation effect and electrical conductivity.

Description

Low-voltage complete equipment drawer major loop contact terminal box

Technical field:

The utility model relates to a kind of contact box, and particularly a kind of low-voltage complete equipment drawer major loop contact terminal box has that versatility is good, characteristics such as low cost of manufacture, insulation property and good heat dissipation effect.

Background technology:

At present, low-voltage complete draw out switchgear drawer major loop contact terminal box all is that three contacts of three-phase or four contacts of three-phase four phases are encapsulated in the box with bigger working of plasticss.Though such design good insulation preformance has guaranteed the security performance of using, owing to adopt bigger working of plastics; A kind of working of plastics that uses a special use that makes up lacks versatility, causes major loop contact terminal box processing cost high; Installation and maintenance are difficulty relatively, and radiating effect is poor.In addition, now a lot of contact box copper contacts adopt switching, and Welding Structure is generally all adopted in switching, owing to be Welding Structure, is easy to generate weld defect, reduces rate of finished products, and influences electric conductivity.

The utility model content:

To the technical deficiency of existing the said goods, the purpose of the utility model just provides a kind of low-voltage complete equipment drawer major loop contact terminal box, and it is made up of moving contact, fixed contact, insulation square box, groove, fixture, recess, projection.

The utility model solves the technical scheme that its technical problem adopted: low-voltage complete equipment drawer major loop contact terminal box is made up of a contact and an insulation square box; Contact is arranged in the insulation booth; On the contact, insulation is respectively arranged with groove and boss in the square box; Contact is fastened on the boss of insulation square box through groove, and through fixture contact is fixed in the insulation square box, and contact is divided into moving contact and fixed contact; The insulation square box outer surface be respectively arranged with recess, projection, such once the insulation square box recess with another the insulation square box projection each other interlock be bolted together.

The utility model beneficial effect: versatility is good, economical with materials, low cost of manufacture, insulation property and radiating effect and the characteristics that conduct electricity very well.

1 moving contact, 2 fixed contacts, 3 insulation square boxes, 4 grooves, 5 fixtures, 6 recesses, 7 projections are described among the figure

Embodiment:

According to Fig. 1, shown in 2, the utility model provides a kind of low-voltage complete equipment drawer major loop contact terminal box, and it is made up of moving contact 1, fixed contact 2, insulation square box 3, groove 4, fixture 5, recess 6, projection 7.Contact is arranged in the insulation square box 3; Low-voltage complete equipment drawer major loop contact terminal box is made up of a contact and an insulation square box 3; On the contact, insulation is respectively arranged with groove 4 and boss in the square box 3; Contact is fastened on the boss of insulation square box through groove 4, and through 5 of fixtures contact is fixed in the insulation square box 3.

Contact shown in Figure 1 is the low-voltage complete equipment drawer major loop contact terminal box of moving contact; Fig. 2 contact is the low-voltage complete equipment drawer major loop contact terminal box structural representation of fixed contact.The dynamic and static state of contact can be changed each other.

For adjacent insulation square box 3 is bolted together, be respectively arranged with recess 6, projection 7 at the outer surface of said insulation square box 3, like this, can sting mutually and be bolted together once the recess 6 and the projection 7 of another insulation square box of insulation square box.

Even be stitched together three four lines or other multichannel contact boxs that becomes the three-phase loop of three contact boxs, four contact boxs then capable of being combined by recess on it 6 and projection 7 to a plurality of identical single-phase contact boxs.

The low-voltage complete equipment drawer major loop contact terminal box that will have moving contact 1, fixed contact 2 plugs together together, can realize the connection of low-voltage complete equipment drawer major loop contact terminal box plug-in unit.

The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalence exchange, all drop in the utility model protection range.
