Detailed Description

The technical scheme of the utility model is further described with the attached drawings:

In this embodiment, preferably, the circular arc protrusion 7 and the attachment surface 2 are integrally formed.

In this embodiment, it is preferable that the barb 6 is a unitary structure, and the barb 6 is disposed along the bottom edge of the abutting surface 2 and the edge of the circular arc protrusion 7.

In this embodiment, it is preferable that the fixing opening 5 is a convex through-groove, the convex portion protrudes outside the attachment surface 2, the size of the inner opening 51 of the fixing opening 5 is larger than that of the outer opening 52, and the hook 3 is hooked at the outer edge of the outer opening 52.

In this embodiment, the fixing opening 5 is preferably a rectangular opening.

In this embodiment, the material of the connection box 1 is preferably a flame retardant material.

In this embodiment, preferably, a through slot 4 is arranged below the hook 3.

Conventional junction boxes do not have the ability to be assembled quickly. The assembly often requires tools to be carried for operation, such as screwing. Visual management cannot be realized while the installation efficiency is greatly reduced. The new connecting box modifies the original two-end eyelets into a flat hole at one end and a barb at the other end; the assembly can be completed by only forcing one button. Like before the trunking and trunking fastening, only fix 4 faces of trunking through connecting box. The connecting box is additionally provided with the barb, so that the advantage that all force application directions inside and outside the wire slot can be locked. The arc bulge in the middle of the connecting box provides enough space for the connection of the wire groove and the wire groove or the wiring and is used for heat dissipation and insulation; meanwhile, the selection of the materials not only enables the product to have extremely high strength, but also enables the product to have a flame retardant function.

This bus duct connecting box passes through barb 6 card with two connecting box 1 on the lower notch of bus duct, and binding face 2 pastes the outer wall at the bus duct, then two connecting box 1 mutually block two bus ducts of fixed connection together through fixed mouthful 5 and pothook 3.
