Abstract

Provided is a waterproof cable joint with a cable protection device. The waterproof cable joint comprises a joint body, a joint core body and a sealing lining, wherein the joint body is in the shape of a circular pipe; the joint core body and the sealing lining are arranged in the joint body; the sealing lining is disposed at the upper side of the joint core body; the upper end of the joint body is connected with a first nut; the inner wall of the upper end of the first nut is in the shape of a conical surface; the first nut extends upwards and is provided with a horn-shaped flared structure; the lower end of the joint body is connected with a second nut; and the lower end surface of the second nut is downwards connected with a horn-shaped flared structure. The first nut compresses the sealing lining to be contracted to fasten and seal a cable. An O-shaped sealing ring is arranged between the joint core body and the joint body so that the problem of water penetration between the joint core body and the joint body under high water pressure is solved, and high sealing effects are achieved. The cable enters the joint body through the horn-shaped flared structures so that the bending radius of the cable is increased, the friction coefficient of the cable is reduced, and the possibility is reduced that the cable may be cut.

Description

The Waterproof cable joint with cable protecting device
Technical field:
The utility model relates to mechanical field, relates in particular to cable connecting device, particularly a kind of Waterproof cable joint with cable protecting device.
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 instructions for use in high pressure high sealing place, and under high pressure, sealing property exists hidden danger, and while particularly applying on blower fan, cable can swing along with the size of wind-force, causes cable jacket layer to be worn incised wound.
Summary of the invention:
The purpose of this utility model is to provide a kind of Waterproof cable joint with cable protecting device, and the described this Waterproof cable joint with cable protecting device will solve that Waterproof connector of cable sealing property in prior art is undesirable, cable jacket layer is easily worn the technical problem of incised wound while applying on blower fan.
This Waterproof cable joint with cable protecting device of the present utility model, comprise joint body, joint core body and seal cartridge, wherein, described joint body is cylindrical, the top and bottom of joint body are respectively arranged with external screw thread, described joint core body is arranged in joint body, described seal cartridge is arranged in joint body and is positioned at the upside of joint core body, the upper end of joint body is connected with first nut, the upper end inwall of the first described nut is the conical surface, the upper-end inner diameter of the described conical surface is less than bottom diameter, the first nut from it in end face the periphery of screwed hole set out, extend upward and be provided with a flare structure, the lower end of joint body is connected with second nut, on the lower surface of the second described nut, be connected with a flare structure downwards.
Further, on the excircle at joint body middle part, be provided with hoop boss, on the downside of described hoop boss and the joint body between the second nut, be arranged with sealing ring.
Further, in the upper end end face of joint core body, be provided with cannelure, described cannelure is inserted in the lower end of seal cartridge.
Further, between the inwall circumferential step of seal cartridge and joint body, be provided with an O-ring seals.
Further, described seal cartridge adopts hydrogenated nitrile-butadiene rubber HNBR material to make.
Further, described joint body is made by one-ton brass HSn62-1 material.
Further, described O-ring seals is made by polytetrafluoroethylmaterial material.
Further, described joint core body is made by PA66 elastomeric material.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model utilizes the inner conical surface compressing seal cartridge of the first nut to shrink, and utilizes joint core body and seal cartridge to the cable fit sealing through joint core body and seal cartridge, realizes good sealing property.Meanwhile, between joint core body and joint body, O-ring seals is set, has solved the problem that has water infiltration in high water pressure lower contact core body and joint body assemblage gap, reach high sealing effect.Cable enters joint body by the flare structure of the second nut and the first nut, has increased the bending radius of cable, has reduced the coefficient of friction of cable, has reduced the possibility that cable is hurt.
Accompanying drawing explanation:
Fig. 1 is the structural representation with the Waterproof cable joint of cable protecting device of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, the Waterproof cable joint with cable protecting device of the present utility model, comprise joint body 1, joint core body 2 and seal cartridge 3, wherein, described joint body 1 is cylindrical, the top and bottom of joint body 1 are respectively arranged with external screw thread, described joint core body 2 is arranged in joint body 1, described seal cartridge 3 is arranged in joint body 1 and is positioned at the upside of joint core body 2, the upper end of joint body 1 is connected with first nut 4, the upper end inwall of the first described nut 4 is the conical surface, the upper-end inner diameter of the described conical surface is less than bottom diameter, the first nut 4 from it in end face the periphery of screwed hole set out, extend upward and be provided with a flare structure, the lower end of joint body 1 is connected with second nut 5, on the lower surface of the second described nut 5, be connected with a flare structure downwards.
Further, on the excircle at joint body 1 middle part, be provided with hoop boss, on the joint body 1 between the downside of described hoop boss and the second nut 5, be arranged with sealing ring 6.
Further, in the upper end end face of joint core body 2, be provided with cannelure, described cannelure is inserted in the lower end of seal cartridge 3.
Further, between seal cartridge 3 and the inwall circumferential step of joint body 1, be provided with an O-ring seals 7.
Further, described seal cartridge 3 adopts hydrogenated nitrile-butadiene rubber HNBR material to make.
Further, described joint body 1 is made by one-ton brass HSn62-1 material.
Further, described O-ring seals 7 is made by hydrogenated nitrile-butadiene rubber HNBR material.
Further, described joint core body 2 is made by PA66 elastomeric material.
The operation principle of the present embodiment is: utilize the inner conical surface compressing seal cartridge 3 of the first nut 4 to shrink, utilize 3 pairs of cable fit sealings through joint core body 2 and seal cartridge 3 of joint core body 2 and seal cartridge, realize good sealing property.Meanwhile, between joint core body 2 and joint body 1, O-ring seals is set, has solved the problem that has water infiltration in high water pressure lower contact core body 2 and joint body 1 assemblage gap, reach high sealing effect.Cable enters joint body 1 by the flare structure of the second nut 5 and the first nut 4, has increased the bending radius of cable, has reduced the coefficient of friction of cable, has reduced the possibility that cable is hurt.
