Abstract

The invention relates to an industrial socket, which can be widely applied to the power transmission and distribution of the electric power, electrical, machinery, factory, mine, construction engineering, exhibition and other fields. The industrial socket has a structure consisting of a socket body and a sheath, wherein the sheath consists of a sheath cover, a sheath base and a sheath bracket; a joint of the sheath base and the sheath cover is provided with a groove used for placing a waterproof sealing strip; the outer edge and inner circle end face of the sheath bracket are both provided with a rubber plastic elastic sealing ring; matching positions of the sheath base, the sheath cover and the sheath bracket are provided with grooves; triangular or trapezoidal bosses are respectively arranged in the grooves; and the rubber plastic elastic sealing ring of the outer edge of the sheath bracket and the triangular or trapezoidal bosses are compressed so as to form linear sealing. The sheath of the invention adopts a split structure, and the joints of the components are all provided with sealing structures, thereby ensuring that waterproof grade can reach IP67. Meanwhile, when the socket body is wired and connected, whether a cable of a wiring terminal falls off or has a short circuit can be clearly seen, thereby effectively avoiding the occurrence of accidents.

Description

Socket for industry

Technical field

The present invention relates to a kind of socket for industry, can be widely used in the fields such as power transmission and distribution of electric power, electric, mechanical, factory, mine, architectural engineering, exhibitions.

Background technology

Present industrial usefulness two kinds of sockets are arranged, a kind of socket for industry is made up of jack body and sheath, sheath is made up of sheath mount and sheath lid again, the sheath cover screw is fixed on the sheath mount, jack body connects with screw with sheath mount.The user only needs the sheath lid is taken off in use, gets final product wiring, the sheath that closes then lid, the use of can switching on.Though such socket easy-to-connect, degree of protection has only IP44, and the environment for use of socket is limited to some extent, and being easy to leak in the rainy day has an accident.In addition, also has a kind of socket for industry, by jack body and sheath form (as Fig. 1, shown in Figure 2), sheath is an integral type, jack body and sheath also connect with screw, though the classification of waterproof of this kind of socket can reach IP67, the user need pull down jack body in use from sheath, then could wiring, therefore the user to use be not easily, and socket uses rigid cable to connect, and need be connected with protecting cover at the rear socket body that carefully connects the wire, need cable this moment to the sheath internal shift, because sheath is one, be difficult to observe at mobile cable and when connecting sheath, whether the wiring end line is pulled off and open circuit or the doubling short circuit takes place.

Summary of the invention

The objective of the invention is to defective, the infant industry socket of a kind of protecting factor height, high safety is provided at existing socket for industry.

Technical scheme of the present invention is as follows: socket for industry is made up of jack body and sheath, sheath is propped up by sheath lid, sheath mount and sheath and is configured to, be provided with the groove that is used to place water-proof sealing strip with sheath lid junction on the sheath mount, wherein, the outer ledge of sheath support and interior nose circle face are equipped with the rubber-plastic elastomer sealing ring; The position that sheath mount, sheath lid match with the sheath support is provided with groove, and, be provided with triangle or trapezoid boss in the middle of the groove; The rubber-plastic elastomer sealing ring of sheath support outer ledge and triangle or trapezoid boss compress the formation linear sealing.

Aforesaid socket for industry, wherein, the rear end of circle is provided with buckle in the sheath support, also is provided with buckle with matching on the back end circumference of jack body, mutual snap-lock, the rubber-plastic elastomer sealing ring in the sheath support on the nose circle face is compressed sealing by jack body.

Aforesaid socket for industry, wherein, the screw hole that is used for fixing sheath support and sheath mount is located at sheath mount seal area inside.

Infant industry provided by the present invention has been adopted split type structure with the sheath of socket, has all added hermetically-sealed construction in the junction of each parts, makes the degree of protection at power supply wiring position can reach IP67; Simultaneously, the user only needs the sheath lid is pulled down in use, can carry out wiring, can know after carefully connecting the wire that the cable of seeing binding post has or not to come off or short circuit, then the sheath lid is loaded onto the use of can switching on, and is easy to operate, avoided the generation of accident effectively.
