Abstract
The utility model relates to a waterproof connector of a cable, which belongs to a protective member of the connecting part of a cable and an electric appliance. A copper protective sleeve 1 is formed by the screw connection of a locking nut 11 and a locking screw cap 12; a rubber sealing body 2 is fixedly connected inside the copper protective sleeve; the bottom inner wall of the rubber sealing body is provided with an inward annular projection 4; the annular projection forms an annular cable test hole 3; the surface of a part where the rubber sealing body 2 and the locking nut 11 are contacted is provided with a circle of convex tooth traces 5. The utility model has the advantages of novel structure, tight contact between the rubber sealing body and a cable, favorable effect of water resistance and favorable effect of dust resistance. Meanwhile, the unique cable test hole can detect whether the diameter of the cable is smaller than the diameter of the cable test hole; cables with diameters smaller than the diameter of the cable test hole are not suitable for the waterproof connector of a cable; only cables with diameters larger than the diameter of the cable test hole can use the waterproof connector of a cable. Thus, sealing effect can be effectively ensured.
Description
Technical field
The utility model belongs to the guard block of cable and electrical connection member.
Background technology
Need dustproof, water-tight device at many electric equipments and cable segment connector, more advanced mode is to adopt the cable waterproof joint at this connecting portion at present, be used for the inside and the outside of electric equipment are completely cut off, with fail safe and the reliability that guarantees this electric equipment.The structure that this kind product adopts mainly is the seal of making at the useful rubber in the inside of brass shell and nylon material, its shortcoming is that sealability is not high enough, cable is not tight with contacting of seal, dustproof, good waterproof effect is affected, and is not suitable for using on the electrical equipment to the sealing requirements strictness.
Summary of the invention
The utility model provides a kind of cable waterproof joint, the bad problem of sealing property that exists with the joint that solves present use.The technical scheme that the utility model is taked is: copper sheath 1 is threaded with lock nut 12 by locking nut 11 and forms, connect rubbery sealed body 2 in this copper sheath internal fixation, inside annular protrusion 4 is arranged on the bottom interior wall of sealing body, this annular protrusion forms the wireline test hole 3 of ring-type, and rubbery sealed body 2 has the tooth trace 5 of a circle projection on the part that contacts with locking nut 11, this part surface.During use, locking nut is screwed on the hole of electrical equipment, cable passes from the inside of seal, tightens lock nut, and the compression seal body closely links together this cable waterproof joint and cable.
Advantage of the present utility model is: novel structure, contact between rubbery sealed body and the cable closely, waterproof and dustproof effective, simultaneously, cable size can be measured less than this hole in exclusive wireline test hole whether, diameter has only diameter to use this joint greater than the cable in this hole less than all inapplicable this joint of the cable in this hole, could effectively guarantee sealing effectiveness.
