Description
Technical Field
The utility model relates to a square sealing connector, concretely relates to square sealing connector who comprises two identical connection pieces.
Background
In general, in a city where subways are built initially, at least the tank box of AFC ground wiring of the first subway is filled with water, and the cable is not uncommon to be soaked in water. Subway owners and engineering units who have been experienced and trained have attracted a great deal of attention to the problem of waterproofing AFC ground wiring channels and boxes.
Initially, subway AFC ground wiring systems were laid using conventional ground socket troughs, boxes. Because the traditional ground wiring system has low waterproof requirement, the protection level is generally within IP 44. After the use of a plurality of AFC systems in China, the following results are found: a large amount of underground water is reserved in the groove box, a part of cables are soaked in the underground water, and the outer skin of the cable is damaged in the construction process, so that the electric leakage condition inevitably exists.
In order to solve the problem of water leakage of a trough and a box of an AFC wiring system of a subway, the protection grade of the trough and the box, namely the water-tight performance, needs to be improved. By demonstration, the protection level is generally to reach IP67 to meet the waterproof requirement. Therefore, some subway AFC ground wiring in China adopts a field welding method to solve the problem because of the waterproof requirement. Since a general steel sheet is surface-treated (generally, a hot dip galvanizing method is used to improve the corrosion resistance of the steel), the general steel sheet is not suitable for on-site welding. Because the field welding can damage the anticorrosive coating on the surface, the welding part can be corroded and damaged in a short time, and the phenomenon of water leakage is easily caused. Of course, this also has a certain waterproof effect, but increases the difficulty of site construction. Meanwhile, the investment is multiplied. The potential safety hazard of fire is increased due to open fire generated by field welding.
Some conventional AFC waterproof sealing connectors are generally formed by two connecting sheets with different structures, so that two sets of dies are required to be respectively produced during production, the production cost is increased, and the production time is prolonged. The direction of the two different connecting sheets needs to be aligned when the two different connecting sheets are assembled on site, the installation time is prolonged, and meanwhile, although the two same connecting sheets are in the existing structural form, the through hole structures installed at the two ends of the connecting sheets are different, so that the installation direction needs to be seen when the connecting sheets are installed.
