Abstract

The utility model relates to a new wiring bus cases for the mother row connection in the electric ark main circuit wiring, comprising a conductive row(6) and a box(2) with a cover plate(1) and a base plate(7); the box(2) has an installation hole(4) for the mother row(3) through, the conductive row(6) is provided with an inner connection end and an outer connection end, the inner connection end is arranged inside the box(2) and contacts with the mother row(3), the box(2) is further internally provided with a pressing device(5) to make the conductive row(6) closely contact the mother row(3). The utility model has the advantages of simple structure, easy installation and small, and meanwhile greatly reducing the cost.

Description

The novel wiring box that confluxes

Technical field

The utility model relates to a kind of wiring that electric cabinet main circuit busbar connects box that confluxes that is used for.

Background technology

The bus of electrical equipment connects in the present electric cabinet, and particularly the bus of miniature circuit breaker connects, most of lead articulating that adopts, and other also have the mixing connection and the comb shape bus-bar that adopt copper bar to add lead to connect.The weak point of such scheme is: lead articulating contact point contact resistance is big, and is easily loosening, and place's fault can cause many places circuit outage; Mixing is linked and packed loaded down with trivial details, and volume is big, and exposed copper bar is difficult for sealing; Comb shape bus-bar combination is dumb, just can't use when the fixing or phase arrangement of modulus is irregular.

Summary of the invention

The purpose of this utility model provides a kind of novel wiring simple in structure, easy for installation, that volume is little box that confluxes.

The technical scheme that realizes above-mentioned purpose is: a kind of novel wiring box that confluxes, comprise busbar and box body, has the installing hole that can pass busbar on the box body, in having, busbar connects end and external connection end, in connect end and be positioned at box body, and contact with busbar, also have the hold down gag that busbar and busbar are closely contacted in the box body.

After adopting technique scheme, connect end and external connection end in busbar has, in connect end and be positioned at box body, and contact with busbar, also have the hold down gag that busbar and busbar are closely contacted in the box body.This simple and compact structure having been dwindled the conflux volume of box of wiring, by hold down gag busbar is closely contacted with busbar, and contact resistance is little, can not become flexible, and the external connection end of busbar can directly link to each other with electrical equipment, install very convenient.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1,4, a kind of novel wiring box that confluxes, comprise busbar 6 and have the box body 2 of cover plate 1, base plate 7, parallel arranged has three of left, center, right can pass the installing hole 4 of busbar 3 on the box body 2, in having, busbar 6 connects end and external connection end, in connect the installing hole 4 that end is positioned at box body 2 the right, and contact with busbar 3, also have in the box body 2 and make busbar 6 and the busbar 3 tight hold down gags 5 that contact.Hold down gag 5 can adopt spring steel plate, and is not only simple in structure, and can save cost.

As shown in Figure 2, busbar 6 in connect the installing hole 4 that end is positioned at box body 2 centres.Similar among all the other structures and Fig. 1.

As shown in Figure 3, busbar 6 in connect end and be positioned at the installing hole 4 on box body 2 left sides.Similar among all the other structures and Fig. 1.

Connect end in the busbar 6 and lay respectively in the different installing hole 4, decide according to the wiring needs.Installing hole 4 can be one also, more than two or three, also be to decide as required.

As shown in Figure 3, busbar 6 has two external connection end.Wherein an end can be used as the bus current input, and the other end can directly link to each other with electrical equipment.Decide as required, install very convenient.

The utility model is according to the number of phases of busbar, can be divided into single-phase, two-phase, three-phase, four reaches five phase formulas mutually.
