Abstract

The utility model relates to a connecting piece of a framework of a floor distribution box, and belongs to the technical field of electrical equipment. The connecting piece comprises a right-triangle-shaped bottom surface, wherein two right-angle sides of the bottom surface extend upwards to form vertical planes; the intersections of the two vertical planes are fixedly connected with each other; one end of one of the two vertical planes adjacent to the intersection extends upwards to form a first upright plane; the other end of the two vertical planes adjacent to the intersection extends upwards to form a second upright plane; and the upper end of the second upright plane extends towards the horizontal direction to form a lap joint plane. When the framework is assembled, the two vertical planes are fixedly connected with two bottom frame profiles in three profile frameworks like rectangular coordinates respectively, and the lap joint plane is fixedly connected with vertical profiles, so that the finally formed floor distribution box has an accommodating space as large as possible, and more loop outlet wires can be arranged; therefore, the box body of the floor distribution box has the advantages of compact structure and smaller occupation area.

Description

Land distribution box framework connector

Technical field

The utility model relates to the connector in a kind of electrical box, and especially a kind of distribution box framework connector that lands belongs to the electric equipment technical field.

Background technology

The distribution box that lands is compared low-voltage distribution cabinet, its main feature is that the components and parts of installing in the case are less, and be breaker of plastic casing, the less element of miniature circuit breaker equal-volume substantially, weight is lighter, so the distribution box general appearance size of landing is less, the width and the degree of depth generally are no more than 600-800mm.It is identical with low-voltage cabinet that tradition is landed the distribution box framework, promptly assembled by C type column and G type cross bearer, only shortens to some extent dimensionally.G type cross bearer is installed on the casing front and back position, 4 of 1 cabinet, and each 2 up and down, and the degree of depth of cross bearer is 100mm.With the dark distribution box of conventional 400mm for example, the degree of depth that the front and back cross bearer is added up just reaches 200mm, remove this part occupation space, the just only remaining 200mm of the turnover space of lines of real element, will certainly be bigger when more if run into the loop to the outlet influence, have drawback undoubtedly so plant assembling: casing can seem heavy, take out space of lines.

The utility model content

The purpose of this utility model is: at the problem that above-mentioned prior art exists, propose a kind of can enlarge tank-volumes land distribution box framework connector, land the distribution box inner space thereby can make full use of.

In order to reach above purpose, the distribution box framework connector that lands of the present utility model has the right-angled triangle bottom surface, two right-angle sides of described bottom surface extend vertical plane respectively up, described two vertical plane intersections are connected mutually, one end of the contiguous intersection of one of described two vertical planes extends first vertical surface up, one end of another contiguous intersection of described two vertical planes extends second vertical surface up, and faying surface is extended towards horizontal direction in the upper end of described second vertical surface.

During assembling, two vertical planes are fixedlyed connected respectively with just as two foundation frame sections in three section material frameworks of rectangular coordinate, faying surface and vertical section bars are connected, thereby make landing of final formation have big as far as possible spatial accommodation in the distribution box, can settle the outlet of more loop, make body structure compactness, floor space less.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the package assembly schematic diagram of Fig. 1.

Fig. 3 is the partial enlarged drawing of Fig. 2.

Embodiment

Embodiment one

Present embodiment land distribution box framework connector basic structure as shown in Figure 1, have right-angled triangle bottom surface 1, two right-angle sides of this bottom surface extend up respectively

vertical plane

2,3, two vertical plane intersections by the welding be connected mutually.End that one end of the contiguous intersections of one of two vertical planes 3 extends another 2 contiguous intersections of first vertical surface, 4, two vertical planes up extends the upper end of second vertical surface, 5, the second vertical surfaces 5 up and extends faying surface 6 towards horizontal direction.

Has round boss spaced apart 7 on each vertical plane, vertical surface and the faying surface respectively.The diameter of described round boss and distribute spacing and the pre-manufactured hole aperture and the distribute spacing of distribution box frame section bar of landing match.

During assembling, the connector of present embodiment with land three frame section bars in the distribution box---framework 8 overlap joints (referring to Fig. 2, Fig. 3) that C type tubing constitutes just as rectangular coordinate, because boss that each face is spaced apart and the pre-manufactured hole on the C type tubing match, fasten mutually when therefore overlapping, make the installation site more accurate, and make framework very firm.

With the dark distribution box of conventional 400mm is example, compared with prior art, present embodiment can not only guarantee installation strength, and good looking appearance, owing to cancelled G type cross bearer, C type tubing only is 25mm, the cabinet depth that is assembled into reaches 350mm, has enlarged markedly casing turnover space of lines, and manufacturing cost also decreases, when ensuring the quality of products, reached energy saving purposes.

In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.

Claims

1. one kind is landed distribution box framework connector, has the right-angled triangle bottom surface, it is characterized in that: two right-angle sides of described bottom surface extend vertical plane respectively up, described two vertical plane intersections are connected mutually, one end of the contiguous intersection of one of described two vertical planes extends first vertical surface up, one end of another contiguous intersection of described two vertical planes extends second vertical surface up, and faying surface is extended towards horizontal direction in the upper end of described second vertical surface.

2. the distribution box framework connector that lands according to claim 1 is characterized in that: have round boss spaced apart on described vertical plane, vertical surface and the faying surface respectively.

3. the distribution box framework connector that lands according to claim 2 is characterized in that: the diameter of described round boss and distribute spacing and the pre-manufactured hole aperture and the distribute spacing of distribution box frame section bar of landing match.
