Abstract
The invention provides a waterproof electric cable junction box, comprising a junction box body and an electric cable. A sleeve is arranged on the junction box body and is connected with the junction box body in a sealed and penetrating manner; the wiring end of the electric cable is provided with electric cable core wires an outer surface of which is stripped; the electric cable core wires are connected with the interior of the junction box body through the sleeve; and a waterproof resin layer is filled at the junction box end of the sleeve. The waterproof resin layer and the electric cable core wires are integrally combined, so that water is prevented from soaking inside the electric cable junction box body from the sleeve; the junction box end of the sleeve is sealed by epoxy resin, so that the waterproof property of the junction box can be greatly improved; and the electric cable at the junction box end of the sleeve is subjected to operations of taking out the outer surface and separating the inner core wires, and is combined with the effect of the epoxy resin, so that water is prevented from entering the junction box due to a capillary effect, and the security property of a submersible electric pump can be improved.
Description
Technical field
The present invention relates to a kind of immersible pump water-proof type cable straight joint, be specially adapted to immersible pump when working under water water droplet be penetrated into the occasion that causes electric leakage in the cable straight joint by capillarity along the exocuticle of cable and the gap of inner core electric wire.
Background technology
Immersible pump is a kind of a kind of device of pumping liquid that motor need to be put under water, because electric pump is worked under water, so waterproof particular importance at terminal box place, the electric leakage of general electric pump is the defective tightness that contacts owing to cable and terminal box, because capillarity water can enter into cable inside along the cable exocuticle, particularly at the exocuticle of cable and the space between the inner core electric wire, this capillarity especially severe, be easy to cause electric leakage, bring very large hidden danger to safety.Mode commonly used is with metal bung flange of cable jacket in producing at present, and metal bung flange and cable are made of one formula, carries out corresponding water-proofing treatment at the position of nut and terminal box again, and this processing mode operation is more and cost is larger.
Summary of the invention
The object of the present invention is to provide a kind of novel cable straight joint, to improve submersible pump in the water resistance at cable and terminal box place, improve the use safety of submersible pump.
For achieving the above object, the technical solution used in the present invention is: a kind of water-proof type cable straight joint, comprise terminal box body and cable, and described terminal box body is provided with sleeve, and described sleeve connects with described terminal box body sealing and is connected; The terminals of described cable are the cable core of peelling off exocuticle, described cable core is linked in the described terminal box body by described sleeve, the terminal box end of described sleeve is filled with the waterproof resin layer, described waterproof resin layer and the blending of described cable core are integrated, and anti-sealing is immersed in the cable terminal box body from sleeve.
Further, little two ends were large in the middle of the aperture of described sleeve can be made as, the aperture of middle aperture is greater than the external diameter of described cable, the macropore that can guarantee like this to pour into the terminal box end of the waterproof resin layer of formation and described sleeve does not stay the gap, to permeate the water of coming in from described sleeve and be isolated in the macropore side that contains the waterproof resin layer, and stop water to be penetrated in the terminal box body by sleeve.
Consider getting both of Financial cost and technique effect, described waterproof resin layer is selected epoxy resin.
The invention has the beneficial effects as follows, the terminal box end epoxy sealing at sleeve has improved water resistance greatly; Cable at the terminal box end of sleeve takes out exocuticle and the operation that separates inner core, and the effect of coupling collar epoxy resins has prevented because the water inlet of capillarity terminal box, has improved the security performance of submersible pump.

Accompanying drawing 2 provides the profile of sleeve of the present invention.
Among the figure, 1. terminal box body 2. sleeves 3. cables 4. cable cores 5. waterproof resin layers.
Embodiment
As shown in Figure 1, a kind of water-proof type cable straight joint comprises terminal box body 1, sleeve 2, cable 3, cable core 4 and waterproof resin layer 5; Described waterproof resin layer 5 is epoxy resin; Described sleeve 2 connects with described terminal box body 1 sealing and is connected; The terminals of described cable 3 are the cable core 4 of peelling off exocuticle, described cable core 4 is linked in the described terminal box body 1 by described sleeve 2, little two ends large (as shown in Figure 2) in the middle of the aperture of described sleeve 2, the aperture of middle aperture should can be passed from sleeve 2 with assurance cable 3 greater than the external diameter of described cable 3, simultaneously, fill with in the macropore of the terminal box end of described sleeve 2 waterproof resin layer 5 is arranged, described waterproof resin layer 5 is integrated with described cable core 4 blendings, and anti-sealing is immersed in the cable terminal box body from sleeve.
Characteristics of the present invention are: by using an independently tube-in-tube structure, to couple together inside and outside the terminal box, and add the epoxy resin of waterproof at the position that connects, increased the water proofing property of sleeve, simultaneously having prevented also that water droplet is penetrated into from the gap of the exocuticle of cable and inner core electric wire by capillarity causes electric leakage in the cable straight joint, promoted the water resistance of submersible pump.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Waterproof material wherein such as epoxy resin are the necessary links of in this programme, but do not limit it; Although with reference to aforementioned each embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that; It still can be made amendment to the technical scheme that aforementioned embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the various embodiments of the present invention skill.
