It is known that equipotential connection is used to connect all metal objects in and near a building, such as steel bars, water pipes, gas pipes and other metal pipelines in concrete, machine metal objects and other large buried metal objects, cable metal shielding layers, zero lines of power systems, and grounding wires of buildings, by electrical connection, so that the whole building becomes a good equipotential body.
At present, in the fields of electrified railways, comprehensive pipe galleries, four-electricity bridge erection, maintenance hanging baskets, fixed drainage pipes, urban rail transit and the like, equipotential connection is required to be carried out in such construction according to the design requirements of lightning protection and grounding. Present general connected mode is with the steel sheet pre-buried inside the wall, through with connection such as outside earth connection and lightning arrester, realizes equipotential connection, but there is the drawback in connected mode here:
(1) the installation part is convenient, a positioning device is not arranged on the steel plate, the position is fixed and cannot be adjusted after the steel plate is embedded, and the operation process of stringing the nets is unfavorable;
(2) when the connecting structure is connected with the channel, the connecting points are more and are mostly fixed by welding, the conduction effect is influenced, local breakdown is easy, and the reliability is poor;
(3) the contact surface with the channel is small, and the conduction performance is poor;
(4) the connection of the whole network can be realized only through the steel plate, and the connection performance with other equipotential connecting pieces is poor.
To sum up, to the drawback in the prior art, as technical personnel in the industry, how to design a pre-buried channel equipotential connecting piece through technical improvement, its simple structure, novelty can realize fine electrically conductive effect is the technological problem that this industry is waited to solve urgently.
SUMMERY OF THE UTILITY MODEL
In view of the above disadvantages of the prior art, an object of the present invention is to provide an equipotential connector for a pre-buried channel, which includes a channel body, wherein a through groove is formed in the channel body, and an opening is formed at the top of the through groove; the connecting head is arranged in the channel body and is of a T-shaped structure, and the connecting head can slide left and right in the channel in a non-tightened state; the connector on be provided with the screw hole of tightening, be provided with a fixed plate in the outside of channel, the fixed plate on be provided with an open slot, be provided with two at least screw holes on the fixed plate, one of them is used for using with the connector is fixed, another screw hole runs through a lateral wall of open slot for the fixed of the inside equipotential connection piece of open slot.
