Detailed description of the invention
The core of the present invention is to provide a kind of cabinet bussed supply and connects sealing structure, so as to
The joint location of cabinet bus with power cable is effectively sealed, thus improves both joints
The class of safety protection of position.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the accompanying drawings
The present invention is described in further detail with detailed description of the invention.
Cabinet bussed supply disclosed in the present embodiment connects in sealing structure, including stretching out cabinet
The cabinet bus 2 of side plate 1, and the externally fed cable 3 being connected with cabinet bus 2, such as figure
Shown in 1 to Fig. 3, in addition, in the scheme disclosed in the present embodiment, also in cabinet side
Protection box body 4 it is provided with outside plate 1, and the connecing of cabinet bus 2 and externally fed cable 3
Head is sealed in protection box body 4.
Owing to the joint of cabinet bus 2 and externally fed cable 3 has been sealed in protection box body 4
In, therefore can be prevented effectively from foreign material and rainwater enters into both joint location, thus effectively
Improve the class of safety protection of both joint location, improve the reliability of equipment work.
As shown in fig. 1, protection box body 4 offered for leading to that externally fed cable 3 passes
Hole, and in through hole, it is embedded with flexible coil 5 excessively, this flexibility crosses coil 5 one aspect can
It is tightly placed on externally fed cable 3, on the other hand can utilize deformation and the protection box of himself
Through hole on body 4 realizes sealing.Skilled addressee readily understands that, flexibility crosses coil
The selection of 5 is not limited to one, and such as rubber crosses coil, coil etc. crossed by silica gel.
Cabinet bus 2 may be copper bar, and this copper bar uses high-purity red copper to make under normal circumstances,
Completed the processing of copper bar shape by machining, the shape of copper bar is usually rectangle, at cabinet
