Abstract
The invention discloses a U-shaped cable bridge with a weak current shielding layer. The U-shaped cable bridge comprises a U-shaped base and an arc-shaped cover plate, wherein the middle parts of two sides of the U-shaped base are each provided with a supporting flange, a U-shaped metal net matched with the inner walls of the U-shaped base is arranged in the U-shaped base under the supporting flanges, an isolating plate is arranged on the supporting flanges, a shielding layer made of electric signal shielding materials is arranged in the isolating plate, one side of the arc-shaped cover plate is hinged to one side of a port of the U-shaped base, a groove is formed in the end part of the other side of the arc-shaped cover plate, and the groove is buckled with a lug boss at the upper end part of the other side of the U-shaped base. The U-shaped cable bridge with the weak current shielding layer is reasonable in structural design, enlarges the placing space of the cable bridge through the cooperation of the U-shaped base and the arc-shaped cover plate, has good radiating effect, shields weak current cables placed therein through the structural design of the U-shaped metal net, and can avoid the interference of a high-intensity magnetic field above the U-shaped cable bridge through cooperation of the isolating plate at the upper part and the structural design of the shielding layer inside the isolating plate.
Description
Technical field
The present invention relates to cable testing bridge field, particularly relate to a kind of U-shaped cable testing bridge with light current screen.
Background technology
Crane span structure is the support of a support and payout, and cable testing bridge is divided into slot type, pellet type and the structure such as ladder-type, grid type.The base plate of existing cable testing bridge is mostly flat, mostly that forceful electric power cable box weak-current cable is put together in use, its weak-current cable signal cable is easily interfered, therefore in order to reduce signal disturbing, between strong and weak cable, preferably Isolated Shield is got up, and the space of cable testing bridge inside is less, thus affect its heat dispersion.
in invention
The object of the invention is the deficiency in order to make up prior art, providing a kind of U-shaped cable testing bridge with light current screen.
The present invention is achieved through the following technical solutions:
A kind of U-shaped cable testing bridge with light current screen, it is characterized in that: include U-shaped base and curved cover plate, the middle part of described U-shaped base both sides is respectively equipped with support rib, the U-shaped wire netting of fitting with its inwall is provided with in U-shaped base below described support rib, described support rib is provided with division board, the screen that signal of telecommunication shielding material is made is provided with in described division board, the side handing-over of described curved cover plate is in the side of U-shaped base port, the end of opposite side is provided with groove, and the boss of groove and U-shaped base opposite side upper end fastens.
Advantage of the present invention is:
Reasonable in design of the present invention, by the cooperation of U-shaped base and curved cover plate, increase the placement space of cable testing bridge, there is certain radiating effect, good heat dissipation effect, by the structural design of U-shaped wire netting, by the weak-current cable shielding be placed in the phase, coordinate the structural design of the division board above it and the screen in division board simultaneously, the interference of the high-intensity magnetic field above it can be avoided.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See accompanying drawing, a kind of U-shaped cable testing bridge with light current screen, include U-shaped base 1 and curved cover plate 2, the middle part of U-shaped base 1 both sides is respectively equipped with and supports rib 3, support in the U-shaped base 1 below rib 3 and be provided with the U-shaped wire netting 4 of fitting with its inwall, support rib 3 and be provided with division board 5, the screen 6 that signal of telecommunication shielding material is made is provided with in division board 5, the side handing-over of curved cover plate 2 is in the side of U-shaped base 1 port, the end of opposite side is provided with groove 7, and groove 7 fastens with the boss of U-shaped base 1 opposite side upper end.
