Abstract
Provided is a cable high pressure resistant waterproof joint. The cable high pressure resistant waterproof joint comprises a joint body, a nylon core sleeve, a sealing member, a first locking nut and a second locking nut. The two ends of the joint body are both provided with outer threads; the nylon core sleeve is arranged in the joint body; the inner side of the joint body is provided with a first sealing ring; the first sealing ring is adjacent to the nylon core sleeve; the sealing member is arranged in the nylon core sleeve; the inner wall of the first locking nut is in the shape of a conical surface; one end of the first locking nut is connected with one end of the joint body and has an inner diameter greater than the inner diameter of the other end of the first locking nut; the outer side wall of the central portion of the joint body is provided with a circumferential boss; the second locking nut us arranged on the other end of the joint body; and a second sealing ring is sleeved on the joint body between the second locking nut and the circumferential boss. According to the utility model, the conical surface of the first locking nut is utilized for compressing the nylon core sleeve to contract so as to compact a cable and realize good sealing performance. The first sealing ring helps to solve the problem that water penetrates in the installation gap between the nylon core sleeve and the joint body under high-pressure water pressure.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to cable connecting device, particularly a kind of cable high-voltage resistant waterproof joint.
Background technology:
In the coupling part of electric equipment and cable, need to dustproof, waterproof, anti-loosening, screening arrangement be set to connectivity port.In prior art, the structure that Waterproof connector of cable adopts is, in brass enclosure interior, nylon core retainer plate, rubber seal are set.Its shortcoming is to meet the use in high pressure high sealing place, and under high pressure, sealing property exists hidden danger, can not meet the use of electric equipment high request.
Summary of the invention:
The purpose of this utility model is to provide a kind of cable high-voltage resistant waterproof joint, and described this cable high-voltage resistant waterproof joint will solve Waterproof connector of cable in prior art and in high pressure lower seal performance, have the technical problem of hidden danger.
This cable high-voltage resistant waterproof joint of the present utility model, comprise joint body, nylon core retainer plate, seal, the first locking nut and the second locking nut, wherein, described joint body is cylindrical, joint body two ends are provided with external screw thread separately, described nylon core is set in joint body, joint body inner side is provided with first sealing ring, the first described sealing ring is adjacent with nylon core retainer plate, described seal is arranged in nylon core retainer plate, the inwall of the first described locking nut is the conical surface, one end of the first locking nut is connected with one end of joint body by screw thread and its internal diameter is greater than the internal diameter of the other end, an end face of the first locking nut and nylon core retainer plate is adjacent, on the lateral wall at joint body middle part, be provided with hoop boss, the second described locking nut is arranged on the other end on joint body by screw thread, on joint body between the second locking nut and described hoop boss, be arranged with second sealing ring.
Further, on the middle part excircle of described nylon core retainer plate, be provided with annular groove, the first described sealing ring is arranged in described annular groove, and the first sealing ring is O-ring seals.
Further, the length of described nylon core retainer plate is greater than the length of joint body.
Further, the outer rim of the hoop boss on the lateral wall of joint body middle part is regular hexagon.
Further, the end of adjacent one end that nylon core is enclosed within itself and the first locking nut is along circumferential its axial crack that is parallel to that is distributed with more than two number.
Further, described seal adopts hydrogenated nitrile-butadiene rubber HNBR material to make.
Further, described joint body is made by one-ton brass HSn62-1 material.
Further, the second described sealing ring is made by polytetrafluoroethylmaterial material.
Further, described nylon core retainer plate is made by PA66 elastomeric material.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges nylon core retainer plate in joint body, utilizes the conical surface compressing nylon core retainer plate of the first locking nut to shrink, thereby compresses cable, realizes good sealing property.Meanwhile, the first sealing ring is set between nylon core retainer plate and joint body, has solved the problem that has water infiltration under high water pressure in nylon core retainer plate and adapter body assemblage gap, reach high sealing effect; The second sealing ring plays protective action in one end of joint body connection device, and when product is installed, the second sealing ring becomes Vertical Compression state, but not radial force, has avoided easy sealing ring torsional deformation and the problem that lost efficacy.
Accompanying drawing explanation:
Fig. 1 is the structural representation of cable high-voltage resistant waterproof joint of the present utility model.
