Abstract

The utility model relates to a connecting joint for solar energy, which comprises a male head and a female head, wherein one end of the male head is provided with a guide pipe, the periphery of the guide pipe is provided with a clamping tenon, and the other end of the male head is provided with a male head screw thread; one end of the female head is provided with a clamping tenon which corresponds to the clamping tenon of the male head, and the other end thereof is provided with a female head screw thread; and the male head screw thread and the female screw thread are provided with a plurality of metal screw nuts. By being combined with a corresponding cable connector by a connecting mode which is similar to the buckling, the connecting joint can realize that a plurality of sleeves can be fast connected with and separated from each other; With the butt joint between a metal inserting needle and an inserting sleeve, the connecting joint can effectively guarantee the requirement of the electric accessing performance; and the connecting joint not only has the function of a water-proof joint, but also can be connected with electrical equipment, thereby being more convenient to connect with the electrical equipment compared with the general connection mode by of the screw pressing or welding, and releasing the assembly workers from the complex installation process.

Description

The solar energy jointing

Technical field

The utility model relates to the joint that a kind of connection cable is used, and especially relates to the cable jointing that a kind of field of solar energy is used.

Background technology

Existing cable jointing mainly is to comprise male plug and female plug, an end connection cable of male plug and female plug, and the other end of male plug is a contact pin, and the other end of female plug is a jack, and contact pin inserts the connection of finishing cable in the jack.This connected mode makes contact pin and jack be easy to be separated from, and makes the interruption of cable work; The phenomenon of loose contact also can appear in contact pin and jack sometimes, and also might produce the phenomenon of electric leakage in the place that water is arranged, and very inconvenient and safety operate.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of can connect fast with separate, conduct electricity very well, solar energy jointing waterproof and dampproof and easy for installation.

The technical scheme in the invention for solving the technical problem is: a kind of solar energy jointing, comprise male and female, and an end of described male is provided with guide pipe, and the periphery of guide pipe is provided with trip, and the other end is provided with the male screw thread; Described female one end is provided with the draw-in groove of male trip correspondence, and the other end is provided with the female screw thread; Described male screw thread and female screw thread are provided with metal nuts.

In order to improve the intensity of female, be distributed with contact-making surface on the described female, indent constitutes, and is provided with reinforcement in the described contact-making surface.

For cable can better be contacted, have good electrical conductivity, be provided with sleeve in the described male; Be provided with contact pin in the described female, described sleeve inwall is provided with the microsprings circle.

For contact pin and sleeve can be fixed in male and the female, the outer wall of described contact pin and sleeve is provided with the hangnail sheet, and the inwall of described male and female is provided with the self-locking collar.

In order to make solar energy operate as normal under water or the moist environment arranged, be provided with sealing ring at the end of male screw thread and female screw thread with jointing.

The utility model has the advantages that: adopt the connected mode of similar buckle that corresponding wire and cable connector is carried out combination, can realize between the sleeve pipe quick connection with separate; By docking between metal ferrule and the sleeve, guarantee effective electric admittance performance requirement; Can play water joint, have electrical equipment to connect again, and connect come convenient, make the assembly crewman from loaded down with trivial details installation process, free than the electrical equipment of general dependence screw crimping or welding.
