Description
Technical field
The utility model belongs to the jockey of electric wire, specially refers to a kind of explosion-proof terminal connection box.
Background technology
The connection terminal box of existing electric wire screen pipe is a monolithic construction, and electric wire passes its inner chamber.For safety anti-explosive, terminal box must be changed after damaging immediately.But easily cause short circuit when changing, inconvenience is installed, is difficult to operation.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of explosion-proof terminal connection box is provided.
The technical scheme that the utility model technical solution problem is adopted is: explosion-proof terminal connection box is made of box body and gland.Box body is that barrel-shaped, inner chamber is the cable storage tank, has two symmetrical all-in-one-pieces screw to be arranged on picking up the ears, picking up the ears in the outer suitable for reading of barrel-shaped box body, and box body is suitable for reading to be to be higher than the annular boss of picking up the ears.The vertical section of gland is n font, end opening and the boss suitable for reading of box body intussusception mutually.To flexible sealing ring between the boss, the caping of gland has the cable perforation for coaxial line suitable for reading with box body to elastic sealing ring between two parties at the inner chamber of gland.The installation screw corresponding with the screw of picking up the ears arranged on the wall of gland, and screw is fastenedly connected box body and gland.
As further improvement of the utility model, the nut of any one screw has at least one pad to can be used as the connector of earth shield cable; The equal electricity consumption insulating material of box body and gland is made.
That explosion-proof terminal connection box of the present utility model has is rational in infrastructure, easy accessibility, advantage such as safe and reliable.
Description of drawings
