Description
Technical field
Piezoelectricity pneumoelectric cable fittings field in the invention belongs to is specifically related to the shielding type separable straight-shaped connector that uses in the switch cubicle distribution.
Background technology
Along with the development of China's power construction, the continuous of electricity needs risen, and the demand of medium-pressure power cable increases day by day, and the midium voltage cable accessory product is being extensive use of, and the midium voltage cable accessory product domesticizes, seriation.The straight shape connect-disconnect plug of silicon rubber in the separable connector of existing similar power cable (hereinafter to be referred as connector), mostly being to adopt relies on watchband to carry out the plug-in product of Elastic Contact, this way of contact contact is few, minimum effectively conductive section deficiency, can't guarantee big electric current operation, generally only accomplish about 200A; The straight type connector of plug-in adopts the Elastic Contact formula to be connected with sleeve pipe, relies on fixed hook to fix, and the mechanical strength deficiency does not have expanded function, can not connect other cables of lightning arrester or tap; Existing similar power cable connector all is to adopt funnel-form Stress Control mode in the lower end of plug, and this kind mode requires every connector can only cooperate the cable of one to two kind of specification, and cost is higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, good seal, the reliability height, through-current capability is strong and have a shielding type separable straight-shaped connector of multiple expanding function.
For achieving the above object, the technical solution used in the present invention is: include conductive gold part, line ear, double threaded screw I, double threaded screw II, stress solid, blanking cover, pad, helmet, the vertical shape coat of this connector by internal layer, middle level and skin the compacting of totally three layers of Different Silicon elastomeric material form; The upper port of vertical shape coat is that the male cone (strobilus masculinus) of inner conical surface and switch cubicle sleeve pipe cooperates, and there is the branch of lateral openings at the middle part, and opening shape is an inner conical, matches with the outer cone of blanking cover, and lower port is cylindric, matches with stress solid on being sleeved on cable; The outer surface of vertical shape coat is used lead ground connection by ground hole; Line ear lower end links to each other with cable core by crimping, and the upper end is pressed between the following transverse plane and pad of conductive gold part, is fixed by double threaded screw II and corresponding bolts; Conductive gold part upper surface is pressed on the metalwork of box face, is fixed by double threaded screw I and corresponding bolts, and the lower end links to each other with the line ear; Blanking cover is inserted in the inner cone of lateral openings of straight shape plug, and front end is tightened the end that is fixed on double threaded screw II by screw thread, and the rear end is covered by the conduction helmet.
The present invention can reach rational in infrastructure by above technical scheme, and each level is in conjunction with closely, and is easy for installation, reliability height and the beneficial effect that possesses expanding function.
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
Present embodiment includes the connector vertical shape coat that formed by internal layer 1, middle level 2 and outer 3 three layers of different silastic materials compacting and conductive gold part 4, line ear 5, double threaded screw I 6, double threaded screw II 7, stress solid 8, blanking cover 9, pad 10, helmet 11, the upper port 12 of vertical shape coat is an inner conical surface, cooperate with the outer cone of switch cubicle sleeve pipe, can guarantee reliably to be connected when the lead-in wire direction is consistent with the sleeve pipe direction, especially it is downward to be fit to the switch cubicle sleeve pipe, the connection when cable is upwards introduced by casing; The branch branch ostium 13 that the middle part of vertical shape coat oriented is side-prominent, opening shape is an inner conical, can with the matching of blanking cover 9, can connect lightning arrester or other cable of tap when needing; The bottom of vertical shape coat is cylindric, cooperates with stress solid 8, and stress solid is sleeved on to be handled on the cable 14 of back; The outer surface of vertical shape coat is used lead ground connection by ground hole 15; Line ear 5 lower ends link to each other with cable core 16 by crimping, and the upper end is pressed between the following transverse plane and pad 10 of conductive gold part 4, is fixed by double threaded screw II7 and corresponding bolts; Conductive gold part 4 upper surfaces are pressed on the metalwork of box face, are fixed by double threaded screw I 6 and corresponding bolts, and the lower end links to each other with line ear 5, and the conductive gold part is to form by T2 copper is silver-plated, and its smallest cross-sectional is 362mm
2, through-current capability is brought up to more than the 630A than the 200A of bolt-type, has satisfied the requirement of straight type connector to big electric current through-current capability, guarantees complete dismantled and assembled property simultaneously; Blanking cover 9 is inserted in the inner cone of lateral openings of straight shape plug, and front end is tightened the end that is fixed on double threaded screw II 7 by screw thread, and the rear end is covered by conduction helmet 11.If desired, this lateral openings inner cone can connect lightning arrester or other cable of tap by other T-shape connectors.
After adopting this programme, cable is connected with conductive gold part, sleeve pipe by stress solid, line ear, and connected mode adopts bolted, can pass through to the directly downward outgoing cable of setting of casing, the metalwork smallest cross-sectional satisfies the requirement by big electric current, guarantees good electric, mechanical performance; The lateral branching opening also has expanded function except the passage that facilitates when installing and removing, can connect lightning arrester or other cable of tap when needed; Independently stress solid possesses plurality of specifications, can better cooperate with multiple cable, and the connector vertical shape coat of single specification can cooperate with the different size stress solid, reduces production costs.
The on-the-spot installation procedure of the present invention is easy, at first with double threaded screw I 6 and corresponding bolts conductive gold part 4 is fixed on the sleeve pipe; By common operation cable is carried out stripping, handle the cable insulation surface, again stress solid 8 is inserted in the good cable of stripping, press connecting ear 5, together with the lower end of stress solid 8 and line ear 5 insertion connectors, guarantee to put in place then; Together with stress solid 8, line ear 5 and cable straight shape connector upper port is enclosed within on the sleeve pipe, makes stomidium coincidence under line earhole and the conductive gold part, be screwed into double threaded screw II 7, shimming 10 is used bolt; Blanking cover 9 is inserted lateral openings and rotation make and put in place, cover tight helmet 11 and promptly accuse and finish.
