Summary of the invention
For the present invention in view of the above-mentioned problems, providing a kind of fire-proof motor cable entry, the introducing device leakproofness is strong, prevents
Shield property is good, has both the effect that anticreep pulls out.
A kind of technical solution according to the invention: fire-proof motor cable entry, it is characterised in that: including explosion-proof shell
Body, the cable leadthrough aperture of the explosion-proof casing are fastenedly connected wire outlet seat chamber, and the wire outlet seat is intracavitary to set two washers, sealing rubber ring
It is set between two washers, anti-explosion cable anchor tip is additionally provided in the axial outer end mounting hole of wire outlet seat chamber, it is described anti-
The axial inner ends of quick-fried cable fixed joint are resisted against in outer washer.
As a further improvement of the present invention, the wire outlet seat chamber includes the interconnecting piece of integrally connected, receiving portion, the company
Socket part is equipped in the cable leadthrough aperture of explosion-proof casing, and receiving portion and interconnecting piece are respectively placed in the two sides of flange face, and lead to
Cross flange face positioning.
As a further improvement of the present invention, the receiving portion inner wall of the wire outlet seat chamber is provided with the protrusion radially extended.
As a further improvement of the present invention, the inner hole axial ends of the anti-explosion cable anchor tip is respectively arranged with circle
Arc chamfering, the axial outer end of anti-explosion cable anchor tip are connected with the locating flange radially extended.
The technical effects of the invention are that: product of the present invention passes through sealant of the EX PACKING GLAND clamping sleeve on cable
Circle is fastened, and the metal washer of two sides is fitted close cable and sealing rubber ring, is prevented to reach locking cable and play waterproof
The effect of dirt, against shock.And clamping ring, the clamp jaw set in EX PACKING GLAND, clamp nut can be further to lead-in cable
Fastening, while playing the role of anticreep and pulling out.
Detailed description of the invention
