The invention discloses a quick connecting type outdoor waterproof electric coupler which is composed of male a joint and a female joint, wherein the male joint and the female joint are in butt joint, the male joint is provided with a cylindrical bore in which the male terminal is arranged, and the female joint is provided with a cylindrical plug in which the female terminal is arranged. The quick connecting type outdoor waterproof electric coupler is characterized in that all male terminals and female terminals are all arranged on the peripheral direction of the same diameter, the connecting part of the female terminals is provided with a U-shaped structure, between the inner wall of the cylindrical bore and the outer edge of the cylindrical plug, one is provided with an L-shaped guide slot, the other is provided with a convex guide pillar, and the bottom surface of the cylindrical bore is provided with an end surface waterproof gasket. When be in connection, the convex guide pillar aims at an axial guide slot of the L-shaped guide slot to cause the cylindrical plug to be inserted into the cylindrical bore; meanwhile, the male terminal is inserted into accommodation space in front of the U-shaped opening of the female terminal; the end surface waterproof gasket forms an end surface waterproof seal between the cylindrical bore bottom surface and the cylindrical plug end surface; when the cylindrical plug rotates one phase angle relatively to the cylindrical bore, the convex guide pillar slides along the peripheral guide slot of the L-shaped guide slot; meanwhile, the male terminal is inserted into the U-shaped structure from the side direction of the female terminal to form the electric connection.

The invention relates to a buoyancy material with a composite sandwich damping structure. The buoyancy material comprises a core material, a plane materiel and a damping coating, wherein the core material is a buoyancy material module; the buoyancy material module comprise epoxy resin, an epoxy reactive diluent, a curing agent, a silane coupling agent and hollow glass beads. The solid buoyancy material module is formed by the processes of premixing, kneading, mould pressing, curing and cutting into solids; the plane material is high-rigidity fiber-enhanced epoxy glass steel, sheet steel or an aluminium alloy plate; the damping coating is a polyether urethane elastomer which is coated between the core material and the core material, between the core material and the plane material, and between the plane material and the plane material. By adopting the buoyancy material disclosed by the invention, the traditional buoyancy material has higher waterproof sealing property and damping property, so that the solid buoyancy material is wider in application range.

The invention discloses a fast-locked connector comprising a socket having a socket outer conductor; a plug having a plug outer conductor; a locking structure for locking or unlocking the plug outer conductor and the socket outer conductor; and sheaths respectively covering the socket outer conductor and the plug outer conductor and for driving the locking structure to perform locking or unlocking operation. In addition, the fast-locked connector also comprises a staple bolt structure arranged on the sheaths and the socket outer conductor for locking or unlocking the sheath with or from the socket outer conductor to prevent unexpected unlocking of the plug from the socket. The fast-locked connector of the invention is simple in structure, and has unexpected unlocking preventing, fast locking and waterproof sealing capabilities. The mechanical structure is high in stability; the working reliability is high; the fast-locked connector can realize tool-free mounting and detachment of a frame body of communication equipment; the dismounting and maintenance operation is simple and convenient; and the competitiveness of products is substantially raised.

The invention relates to a wire or cable waterproof fast-installed connector comprising one housing, two end cover, two sealing rings, and a wire or cable connectors. The housing is a hollow tubular structure. Annular teeth are symmetrically disposed on both ends of the housing. The outer surfaces of the annular teeth are provided with arc surfaces or conical surfaces. External thread connecting surfaces are arranged between the annular teeth and the main body of the housing. The inner surfaces of the end covers are correspondingly provided with matched inner thread connecting surfaces, arc surfaces, or conical surfaces. The wire or cable connectors are disposed in the housing. The two sealing rings are embedded in the annular teeth. The two end covers are connected with the external thread connecting surfaces on both sides of the housing respectively. Thus, the wire or cable connectors form a sealing waterproof structure. The wire or cable waterproof fast-installed connector is good in sealing and waterproof performance, convenient and fast to install and uninstall, overcomes defects of complex structure and complicated operation of a conventional cable connector, and is improved in waterproof sealing performance and damage and tensile failure resistance, suitable for cables in various specifications, large in application range, and high in reliability.
