Description
Technical Field
The utility model belongs to the technical field of wire slot connection, and particularly relates to a tightening type wire slot connector.
Background
Generally, in cities of the first subway, at least the tank boxes of the AFC ground wiring of the first subway are filled with water, and the cable is not uncommon to be immersed in the water. The subway owners and engineering units with experience training have paid great attention to the waterproof problem of the AFC ground wiring groove and the box.
Initially, subway AFC floor wiring systems were laid using conventional floor socket slots, boxes. Since the waterproof requirements of conventional ground wiring systems are not high, the protection level is generally within IP 44. After the domestic multiple AFC systems are used, the following steps are found: a large amount of groundwater is reserved in the tank box, a considerable part of cables are soaked in the groundwater, and certainly, the outer skin of the cables is damaged in the construction process, so that the electric leakage condition is necessarily present.
In order to solve the problem of water leakage of the subway AFC wiring system groove and box, the protection level of the groove and box, namely the water sealing performance, is required to be improved. By demonstration, the protection grade generally reaches IP67 to meet the waterproof requirement. Therefore, some subway AFC ground wiring in China solves the problem by adopting a field welding method because of water resistance. Because the common steel plate is subjected to surface treatment (the corrosion resistance of the steel is improved by adopting a hot galvanizing method), the common steel plate is not suitable for being welded on site. Because the on-site welding can damage the anticorrosive coating on the surface, the welding position can be corroded and damaged in a short time, or the phenomenon of water leakage is easily caused, based on the reasons, the domestic multi-subway AFC ground wiring system adopts stainless steel materials to form grooves and boxes, and then the grooves and boxes are assembled and welded on site, so that the waterproof capacity of the grooves and the boxes is improved. Of course, this also plays a role in some waterproofing, but increases the difficulty of construction on site. And the investment is multiplied. Open fire can be generated due to field welding, and the potential safety hazard of fire is increased.
Some existing AFC waterproof sealing connectors generally adopt two connecting sheets with different structures or the same structure, and then the connecting sheets are oppositely connected and fixed through bolts. But in the subsequent use process, the wire groove box is generally subjected to external impact and other conditions, so that the wire groove box transversely moves in the laying direction, and the sealing waterproof performance of the wire groove is affected.
