Abstract
The utility model discloses a direct introducing structure of an explosion-proof electrical wire. The direct introducing structure comprises a compression nut, a check ring, a wire outlet, a sealing ring and a locking screw, wherein the wire outlet penetrates through an electrical shell, the left side is fixed by the check ring, the right side is fixed by the locking screw, the left side of the wire outlet is provided with a hole groove extending to the internal part of the wire outlet, the sealing ring is installed in the hole groove inside the wire outlet, the outer side of the sealing ring is fixed by the compression nut, and the sealing ring and the wire outlet are both provided with a through hole in the axis direction. Therefore, the wire comes into the internal part of the electrical shell through the through holes of the wire outlet and the sealing ring and is connected with a connection terminal inside the electrical shell, and the wire can be sealed and fixed in the sealing ring by using a sealant. The direct introducing structure further comprises a metal gasket which is installed in the hole groove of the wire outlet at the inner side of the sealing ring. The direct introducing structure has the beneficial effects of simple structure, low manufacturing cost, convenient installation, and ability of meeting requirements of sealing and explosion suppression.
