Abstract
The invention provides a waterproof stress cone. The water stress cone comprises a main cone body, an elastic sleeve and a sealing plug, wherein a cable passage which passes through the main cone body in the axial direction is formed inside the main cone body, the lower end of the main cone body is sleeved with the upper end of the elastic sleeve, and the sealing plug is detachably arranged at the lower end of the elastic sleeve in an inserted mode. The sealing plug is arranged at the tail portion of the stress cone in a matched model, the sealing plug is sleeved with the elastic sleeve in a sealed mode, so that the vacant cable passage of the stress cone in a cable box can maintain a dry state for a long tome, the possibility that water film is formed on the surface of the cable passage is effectively reduced, the possibilities of electric shelf depreciation and electric leakage after the vacant stress cone is put into use are effectively reduced, and the safety of application of the stress cone is improved.
Description
Technical field
The present invention relates to a kind of stress cone of cable termination annex, particularly relate to a kind of waterproof stress cone.
Background technology
China's cable manufacturing techniques has had significant progress in recent years, but the development of HV cable accessories but relatively lags behind, and there are some researches show, electric power system fault probability of happening accounting over half be electric cable accessories failure problems.Electric cable accessories comprises cable termination and joint, cable joint or terminal are connected with other conductors or electric equipment to make conductor, the manufacturing cable head process related to, metallic shield sheath and insulation is often needed to cut off and peel off, exposed cable line needs to configure superior stress cone, the axial stress concentration problem at cable joint place during to overcome energising.
In the prior art, usually multiple stress cone is configured with in cable box, demand in actual applications for number of cables is different, often occur in cable box that part stress cone is temporarily in blank state, and existing stress cone afterbody is through-hole structure, this just makes the cable passage in stress cone and the external world be in connected state.In rainy day or moister region, although rainwater can not flow to cable passage, the steam in air can form water membrane in cable passage surface attachment.Such stress cone is when putting into cable energising, and high-tension electricity under the effect of moisture film, leakage of electricity phenomenon may occur, and makes cable box there is very large potential safety hazard.
Summary of the invention
The present invention be directed to the deficiencies in the prior art, a kind of waterproof stress cone is provided, to overcome existing stress cone when vacant, its cable passage and the external world are in connected state, cable passage surface easily forms moisture film, and then leaks electricity when causing this stress cone to use, and there is the problem of potential safety hazard.
Object of the present invention realizes by following technical solution:
A kind of waterproof stress cone, is characterized in that, comprises that inside is formed with the main cone body of cable passage through vertically, upper end is set in the spring-backed quill of main cone body lower end and is removably plugged in the sealing plug of spring-backed quill lower end.
Further, described spring-backed quill is that electric silica gel is one-body molded.
Further, the bore of described spring-backed quill lower end is less than the diameter of sealing plug periphery.
Further, described main cone body comprises main pipe, arrange the connecting portion of main pipe upper end and be arranged on the rear of main pipe lower end, and described rear and main pipe junction form bossed spacing ring, and described spring-backed quill is set in rear and withstands spacing ring.
Further, described connecting portion upper end is formed with seal groove, and described seal groove is provided with seal washer.
Further, the outer peripheral face of described main pipe is furnished with stiffener.
Further, described stiffener and main pipe one-body molded.
Further, described sealing plug is that rubber is one-body molded.
The present invention has following beneficial effect:
The lower end of the spring-backed quill of waterproof stress cone of the present invention is dismountable is inserted with sealing plug, stress cone inside is made to be the space of an airtight sealing, this makes can keep dry state for a long time in the cable passage of stress cone vacant in cable box, effective reduction cable passage surface forms the possibility of moisture film, effectively reduce the possibility that this vacant stress cone enables rear generation leakage of electricity, electric leakage, effectively improve the fail safe of stress cone application.
In addition, connecting portion upper end fitting tight packing ring, is conducive to the sealing of the junction of improving connecting portion and cable termination, is conducive to the sealing improving cable passage, further increases the fail safe of stress cone application.
The bore of spring-backed quill lower end is less than the diameter of sealing plug periphery, and being conducive to sealing plug, to be plugged in spring-backed quill lower end more firm.
Spring-backed quill is one-body molded by electric silica gel, and the stress that can reduce stress cone inner cable is concentrated, and increases conductive area.
The top of connecting portion is provided with seal washer, improves the sealing of stress cone.
The outer peripheral face of main pipe is furnished with stiffener, makes the structure of main pipe more firm firm.
Accompanying drawing explanation
Fig. 1 be waterproof stress cone partly cut open structural representation.
Embodiment
A kind of waterproof stress cone provided by the invention, effectively can reduce the possibility that stress cone inner cable channel surface forms moisture film, waterproof stress cone as shown in Figure 1, comprises that inside is formed with the main cone body 1 of cable passage 14 through vertically, upper end is set in the spring-backed quill 2 of main cone body 1 lower end and is removably plugged in the sealing plug 5 of spring-backed quill 2 lower end.Each parts annexation and function are described below:
Main cone body 1, comprise main pipe 12, be arranged on the connecting portion 11 of main pipe 12 upper end and be arranged on the rear 13 of main pipe 12 lower end, concrete, connecting portion 11, main pipe 12 and rear 13 can be integrally connected shaping successively, and main cone body 1 inside is formed with the cable passage 14 of through connecting portion 11 vertically, main pipe 12 and rear 13.
The upper end of connecting portion 11 is formed with seal groove 110, seal groove 110 is provided with seal washer 4.
The outer peripheral face of main pipe 12 is furnished with stiffener 121, and promising four stiffeners 121 of the preferred equivalent arrangements of the present invention, not only save material but also make main pipe 12 firmer.Described stiffener 121 one end is connected with connecting portion 11, the other end along the in axial direction extension of main pipe 12, described stiffener 121 and main pipe 12 one-body molded.
The outer peripheral face upper process of rear 13 is formed with spacing ring 131, concrete, bossed spacing ring 131 is formed at rear 13 and the junction of main pipe 12, spring-backed quill 2 is set on rear 13 and withstands spacing ring 131, concrete, described spring-backed quill 2 is in axial direction set on rear 13 until withstand spacing ring 131.
