Description

Separable combined connector for power cables
Technical field:
The present invention relates to the electric cable accessories technical field used in the power cable engineering, refer in particular to a kind of separable combined connector for power cables.
Background technology:
Silicone rubber sleeve in the separable connector of the cable of prior art (hereinafter to be referred as the connector) combination is to add a layer thickness by two layers of silastic material to make less than 1 millimeter sprayed on material; The main part of its connector combination: by two identical connectors of shape, a transition bus (perhaps being middle connector) is formed.This structure following shortcoming arranged: first, leading of silicon rubber appearance spraying by material. in filthy environment, it is big with the resistance change to come off easily, make connector appearance charging operation, one can not guarantee electrician's handling safety, cable and power equipment are burnt in its two connectors surface charging operation heating easily; The second, increase the transition bus product linkage interface is increased, unreliability, shielding properties descends.Integral body takes up room bigger, can not be installed in the general SF6 switch cubicle.The 3rd, there is unstable structure in the galvanic circle during it connects.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, and a kind of rational in infrastructure, combination seal, separable combined connector for power cables that reliability is high are provided.
For achieving the above object, technical scheme provided by the invention is: include front connector rubber sleeve, two of double threaded screws, conducting rod, back connector rubber sleeve, nut group, blanking cover, helmet, two of terminals, two of stress solids, front connector rubber sleeve and back connector rubber sleeve by internal layer, middle level and skin totally three layers of Different Silicon elastomeric materials compacting form; Front connector rubber sleeve front and rear inner chamber all is an inner conical, the bottom is straight tubular, there is ground hole the outside, the front portion covers on the male cone (strobilus masculinus) of sleeve pipe, terminal on the stube cable core of middle part, the male-tapered of rear portion and back connector rubber sleeve directly cooperates, and cable is installed by stress solid in the following hole of bottom; Back connector rubber sleeve front portion is a male-tapered, and there is support tube inside; The rear portion inner chamber is an inner conical, the bottom is straight tubular, there is ground hole the outside, cable is installed by stress solid in the following hole of bottom, the anterior rear portion that directly is engaged in front connector, the middle part connects the terminal on another cable core, and fastening by the nut group, the cone match of rear portion and blanking cover, helmet are enclosed within the afterbody of blanking cover.
The present invention is by above technical scheme, and in the middle of the connector rubber sleeve and back connector rubber sleeve does not need the transition bus.Do not increase whole linkage interface, guarantee electric property.Shortened the overall dimensions of this combination simultaneously, it is little that it is taken up room, and can be installed in the general switch cubicle.Reached beneficial effect rational in infrastructure, that each layer combination is tight, easy for installation, reliability is high.
Description of drawings:
The invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing 1 is a structure cutaway view of the present invention;
Embodiment:
See shown in the accompanying drawing 1:
Present embodiment mainly is made up of front connector rubber sleeve 1,2 two of double threaded screws, conducting rod 3, back connector rubber sleeve 4, nut group 5 (containing plain cushion, bullet pad), blanking cover 6, helmet 7, terminal 81 and 82, stress solid 91 and 92.The silicone rubber sleeve 1 of the front connector among the present invention, and the silicone rubber sleeve 4 of back connector all be by internal layer, middle level, skin, totally three layers of silastic material constitute.It is to make at the different silastic material of mould inside adding of HTHP.Each layer combination is tight, and particularly outer layer thickness is 3mm, and the tenable environment dirt can not come off, the reliability height.Front connector and latter linked rubber sleeve skin after ground hole ground connection, have shielded the high voltage electric field in middle level, and its whole appearance presents earth potential, and people's hand can touch and not have the electric sensation of fiber crops, guarantee electrician's handling safety.Make the plug appearance be difficult for heating simultaneously, reduce the source that accident potential takes place.Its internal layer plays shielding action to terminal position, the sleeve pipe interface position of cable core; The sealed insulation effect is played to the electrification in high voltage position in the middle level.
Galvanic circle of the present invention is from plane → conducting rod 5 left ends of the copper end face → the first terminal of sleeve pipe → conducting rod right-hand member → second terminal plane.Wherein all double threaded screws 2 and nut group do not sandwich between the conducting surface, can guarantee that therefore conductive resistance is little and conduction is reliable.The galvanic circle is simple and reliable, has not only guaranteed minimum electric contact-making surface but also has guaranteed the mechanical strength of stressed member.Effectively reduce because the bad conduction outgoing cable heating accident of contact-making surface.
The concrete structure of present embodiment is: front connector rubber sleeve 1 front and rear inner chamber all is an inner conical, the bottom is straight tubular, there is ground hole the outside, the front portion covers on the male cone (strobilus masculinus) of sleeve pipe, terminal 81 on the stube cable core of middle part, the male-tapered of rear portion and back connector rubber sleeve 4 directly cooperates, and cable is installed by stress solid 91 in the following hole 10 of bottom; Back connector rubber sleeve 4 front portions are male-tapered, and there is support tube inside; The rear portion inner chamber is an inner conical, the bottom is straight tubular, there is ground hole the outside, cable is installed by stress solid 92 in the following hole 11 of bottom, the anterior rear portion that directly is engaged in front connector, the middle part connects the terminal 82 on another cable core, and fastening by nut group 5, the cone match of rear portion and blanking cover 6, helmet 7 is enclosed within the afterbody of blanking cover 6.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
