Description
Technical field
The present invention relates to a kind of cable joint, especially relate to a kind of waterproofing type prefabricated cable straight coupling.
Background technology
The Main Function of cable joint makes circuit unobstructed, makes cable keep sealing, and ensure the class of insulation at cable joint place, make it run safely and reliably.If poor sealing, moisture can invade cable inside, and creepage causing punctures along face to make cable.Therefore cable joint barrier propterty and cost of manufacture are that it evaluates the emphasis considered.
Summary of the invention
Object of the present invention be exactly provide that a kind of structure is simple, volume is little to overcome defect that above-mentioned prior art exists, protection and the stable waterproofing type prefabricated cable straight coupling of water resistance.
Object of the present invention can be achieved through the following technical solutions:
A kind of waterproofing type prefabricated cable straight coupling, comprise high voltage shield, reinforced insulation layer, out semiconductor layer, stress cone, waterproof shirt rim and waterproof grommet, described high voltage shield is set in outside cable, described reinforced insulation layer is set in outside high voltage shield, described out semiconductor layer is set in outside reinforced insulation layer, described stress cone is arranged at the two ends of reinforced insulation layer axial direction, described waterproof shirt rim is arranged on out semiconductor layer two ends, and described waterproof grommet is arranged on inside stress cone.
The length of described high voltage shield, reinforced insulation layer and out semiconductor layer axial direction increases successively.
Described waterproof grommet is provided with twice.
The length of described waterproof shirt rim, between 25mm ~ 35mm, can meet waterproof sealing demand during cable bend.
Compared with prior art, structure of the present invention, through finite element analysis optimization, makes the inner field intensity of joint more reasonable, and improves the interface pressure of product, effectively can reduce the interior creep distance of joint, such that small product size is less, performance is more stable; In addition, add water resistance by design waterproof grommet, and waterproof shirt rim can appropriate cable bending, ensures the water resistance in bending situation.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the enlarged drawing of fitting end.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of waterproofing type prefabricated cable straight coupling, comprises high voltage shield 1, reinforced insulation layer 2, out semiconductor layer 3, stress cone 4, waterproof grommet 5 and waterproof shirt rim 6.High voltage shield 1 is set in outside cable, reinforced insulation layer 2 is set in outside high voltage shield 1, out semiconductor layer 3 is set in outside reinforced insulation layer 2, stress cone 4 is arranged at the two ends of reinforced insulation layer 2 axial direction, waterproof shirt rim 6 is arranged on out semiconductor layer two ends, and waterproof grommet 5 is arranged on inside stress cone.
This joint is only provided with three-decker, and structure is simple, and volume is little, and consumptive material is few, is convenient to manufacture, saves cost; High voltage shield 1 adopts liquid semi-conductive silicone rubber, and reinforced insulation 2 adopts fluid insulation silicon rubber, and out semiconductor layer 3 adopts liquid semi-conductive silicone rubber, makes joint performance more excellent more stable.The structure of this joint, through finite element analysis optimization, makes the inner field intensity of joint more reasonable, and improves the interface pressure of product, effectively can reduce the interior creep distance of joint, such that small product size is less, performance is more stable
Joint two ends increase waterproof shirt rim 6 and waterproof grommet 5 designs, as shown in Figure 2, waterproof grommet 5 is positioned at stress cone 4 inwall, one total twice, waterproof shirt rim 6 is positioned on out semiconductor layer 3, coordinate certain magnitude of interference, the effect of waterproof sealing can be played when nothing increases around any waterproof material.The length of waterproof shirt rim 6, between 25mm ~ 35mm, can bend by appropriate cable, ensures that the joint waterproofing performance in bending situation meets design requirement equally.
