Abstract
An anti-leakage cable joint comprising an outer sheath, an inner sheath and an outer connection base is characterized in that the inner sheath wherein comprises a line inlet portion and a line outlet portion in a sealed state, and a solid copper stick joint is arranged on the line inlet portion and the line outlet portion. Compared with the prior art, the anti-leakage cable joint of the inventionadopts non-continuous wire sealing and the solid copper stick joint arranged between the line inlet and the line outlet can achieve electrification between the line inlet and the line outlet, whereinthe solid copper stick joint is tightly covered by an epoxy resin and a rubber to form a fully sealed joint, which can bear a high voltage of 2 MPa without leakage. The line inlet end can prevent thewater from entering the motor, and the line outlet end can prevent the oil from overflowing through the line core and the line skin and from entering the cable to damage the cable. Accordingly, the anti-leakage cable joint has an excellent sealing performance.
Description
Technical field
The present invention relates to a kind of cable joint, particularly a kind of leak-proof cable joint that is used on the immersible pump.
Background technology
In the prior art, the sealing problem of the cable interface section of immersible pump is a big old difficult problem always, many immersible pumps are just scrapped because of the sealing problem of its cable, reaction according to some manufacturers, most immersible pump is bad to be because the sealing property of the wiring of cable is bad, thereby cause the water inlet of the inside oil-feed or outside to cause short circuit, cause pump not work and scrap.And prior art fails to tackle the problem at its root always, great majority are to adopt to wrap which floor overcoat in the outside of electric wire more, or by adding thick protection layers increase sealing, though some sealing property is done well, but service time one, a lot of problems will appear in length, caused problems such as sealing difference such as ageing of rubber.
Summary of the invention
For solving the weak point that leak-proof cable joint of the prior art exists, provide a kind of aesthetic in appearance, long service life, leak-proof cable joint that unfailing performance is good.
For addressing the above problem, leak-proof cable joint of the present invention, comprise an oversheath, one inner sheath and outer Connection Block three parts, described oversheath tightly protects inner sheath, described outer Connection Block and oversheath link into an integrated entity, described inner sheath adopts epoxy resin and butyronitrile resin material to make, it is characterized in that: described inner sheath is divided into inlet wire part and outlet part, described inlet wire part and outlet partly are sealing state, junction in described inlet wire part and outlet part is provided with a copper rod entity joint, make the energising of turnover line by copper rod entity joint conduction, the inner sheath that copper rod entity joint is made with epoxy resin and butyronitrile resin material is tightly shut, and forms a joint of sealing fully.
Leak-proof cable joint of the present invention also comprises and has a following feature:
Described copper rod entity joint has an inlet wire interface and and goes out line interface, and the inlet wire interface is connected with inlet wire, goes out line interface and is connected with outlet.
The copper rod entity inlet wire interface of described inner sheath inlet wire part and inner sheath outlet copper rod entity partly go out line interface and are communicating state not.
Compared with prior art, leak-proof cable joint of the present invention, what adopt is non-continuous conductors sealing, one copper rod entity joint is set between inlet wire and outlet, realize the energising of turnover line by copper rod entity joint conduction, copper rod entity joint is tightly wrapped in epoxy tree and the rubber, it is shut joint that seals fully of formation, this joint can bear the high pressure of 2MPa and can not leak, at inlet wire one end, can seal water and can not enter motor, can prevent at outlet one end that oil from overflowing between can be by core line skin and enter cable, thereby destroy cable.Therefore its sealing property is extraordinary.
Description of drawings
Below in conjunction with the drawings and specific embodiments leak-proof cable joint of the present invention is described further:
Fig. 1 is the structural representation of leak-proof cable joint of the present invention.
Among the figure:
1 inlet wire, 2 inner sheath inlet wire parts, 3 oversheaths
4 outer Connection Block 5 inlet wire interfaces 6 copper rod entity joints
7 inner sheath outlet parts 8 go out line interface 9 outlets
Embodiment
As shown in Figure 1, leak-proof cable joint of the present invention comprises an oversheath 3, an inner sheath (2,7) and outer Connection Block 4 three parts.
As shown in Figure 1; outer Connection Block 4 is connected as a single entity with oversheath 3; oversheath 3 is the protection of outermost one deck of cable; cable there is a preliminary sealing and a protection; oversheath 3 tightly protects inner sheath (2,7); the inner sheath (2,7) that adopts epoxy resin and butyronitrile resin material to make is divided into inner sheath inlet wire part 2 and inner sheath outlet part 7, and the core of cable separates in inner sheath (2,7) the inside and by inner sheath (2,7).
As shown in Figure 1, inner sheath inlet wire part 2 and inner sheath outlet part 7 for sealing not communicating state, are provided with a copper rod entity joint 6 in the junction of inner sheath inlet wire part 2 and inner sheath outlet part 7 in the coupling part.Copper rod entity joint 6 is formed a joint of sealing fully by inner sheath inlet wire part 2 and inner sheath outlet part 7 shutting tightly.Copper rod entity joint 6 has an inlet wire interface 5 and and goes out line interface 8, inlet wire interface 5 is connected with inlet wire 1, go out line interface 8 and be connected with outlet 9, inlet wire interface 5 with go out the joining of line interface 8 and electric wire for being connected with specific purpose tool, make it have good electric conductivity.Just can be by so a kind of mode of connection so that good seal performance, its inlet wire 1 is not a same core with outlet 9, its connection is to connect by the copper rod entity joint 6 that conducts electricity very well, and copper rod entity joint 6 is by being sealed in inner sheath inlet wire part 2 and the inner sheath outlet part 7 tightly, formed an extraordinary seal nipple, so its sealing property is that prior art is incomparable.
, but should be understood that under the situation that does not break away from relevant protection range defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
