The utility model content
By transformation and the use to end shield lead-in wire end cap, reach the target of on-line monitoring, to install smoothly and test creates favorable conditions for this type of equipment on-line monitoring device from now on, the utility model provides a kind of on-line monitoring special-purpose end shield deriving structure.
The technical scheme in the invention for solving the technical problem is: the special-purpose end shield deriving structure of a kind of on-line monitoring, comprise end shield extension line terminal and protecting cover, and it is characterized in that,
Described end shield extension line terminal is comprised of end shield guide rod, insulation barrier, ground connection sliding sleeve, end shield shell and sliding sleeve spring, described end shield guide rod is nested with in the end shield shell, described insulation barrier is fixed between end shield guide rod and the end shield shell, described ground connection sliding sleeve is nested with at the end shield guide rod terminal, and described ground connection slides in the end shield enclosure cavity and slidably installs, some sliding sleeve springs are installed between ground connection sliding sleeve and insulation barrier, thus the ground connection sliding sleeve relatively the end shield guide rod slide vertically;
Described protecting cover is drawn guide rod, anti-suspension spring, sealing ring, securing member and lead-in wire crimp assemblies by insulating shield main body, end shield and is consisted of, one end of described insulating shield main body connects with the end shield shell by screw thread, and the other end is installed end shield and drawn guide rod; Described end shield is drawn the guide rod middle part and is fixed on the insulating shield main body by securing member, and described end shield is drawn the guide rod outer end and is used for installing the lead-in wire crimp assemblies by screw thread, and described anti-suspension spring fitting is in end shield is drawn the spring cavity of guide rod the inner.
Between described end shield shell and the insulating shield main body, end shield draws between guide rod and the insulating shield main body inner chamber rubber seal ring is set respectively, can reach dustproof purpose, places entering of extraneous dust.
The beneficial effects of the utility model are: the utility model is original end shield to be drawn line end get a kind of improvement, reaches the target of on-line monitoring, for this type of equipment on-line monitoring device is from now on installed and test creates favorable conditions smoothly.Wherein end cap and center conductor adopt respectively teflon and copper material machined, and the anti-suspension spring of internal configurations guarantees that the end shield guide rod draws guide rod with end shield and contact well, and a threat personnel and equipment prevent from suspending.Simultaneously, of the present utility model simple in structure, and its insulation, reliable, sealing, durable, be easy to promote.
Description of drawings
Fig. 1 is the original structure synoptic diagram;
Fig. 2 is the open mode of structural representation of the present utility model;
Fig. 3 is the installment state of structural representation of the present utility model;
Among the figure: 11 end shield guide rods, 12 insulation barriers, 13 ground connection sliding sleeves, 14 end shield shells, 15 sliding sleeve springs, 21 insulating shield main bodys, 22 end shields are drawn guide rod, 23 anti-suspension springs, 24 sealing rings, 25 securing members, 26 lead-in wire crimp assemblies, 2 insulation lids, 3 ground wires.
Embodiment
Such as Fig. 2, shown in Figure 3,
The special-purpose end shield deriving structure of a kind of on-line monitoring comprises end shield extension line terminal and protecting cover.By the structure of protecting cover is improved reach can on-line monitoring purpose.
End shield extension line terminal is comprised of end shield guide rod 11, insulation barrier 12, ground connection sliding sleeve 13, end shield shell 14 and sliding sleeve spring 15.End shield shell 14 wherein is metal shell, and end shield guide rod 11 is the metallic copper bar, and the end shield guide rod is nested with in the end shield shell, and insulation barrier 12 is fixed between end shield guide rod and the end shield shell, and the three forms one.Ground connection sliding sleeve 13 is nested with at the end shield guide rod terminal, and ground connection slides over slidably installation in the end shield enclosure cavity, the parts of an activity of formation.Some sliding sleeve springs 15 are installed between ground connection sliding sleeve and insulation barrier, and the sliding sleeve spring is exactly common spring, thus the ground connection sliding sleeve relatively the end shield guide rod slide vertically.So ground connection sliding sleeve 13 is mobilizable, have certain activity space, the ground connection sliding sleeve is the insulation material, effect is to strengthen the end shield guide rod to be connected the fixing of guide rod with end shield and to be connected effect.
Protecting cover is drawn guide rod 22, anti-suspension spring 23, sealing ring 24, securing member 25 and lead-in wire crimp assemblies 26 by insulating shield main body 21, end shield and is consisted of.Insulating shield main body 21 is the teflon material, has good insulating property, and an end of insulating shield main body 21 connects with the end shield shell by screw thread, and the other end is installed end shield and drawn guide rod.It is a copper bar that this end shield is drawn guide rod 22.This end shield is drawn guide rod 22 middle parts and is fixed on the insulating shield main body by securing member 25, for solid-state.End shield is drawn guide rod 22 outer ends and is used for installing the lead-in wire crimp assemblies by screw thread, is used for connecting ground wire 3.Anti-suspension spring fitting prevents floating of end shield guide rod when being used for cooperating in end shield is drawn the spring cavity of guide rod the inner, carry out good contacting so that the end shield guide rod is drawn guide rod with end shield.
Between end shield shell 14 and the insulating shield main body, end shield draws between guide rod and the insulating shield main body inner chamber rubber seal ring 24 is set respectively, can ensure inner cleaning.
End shield guide rod in this structure and end shield are drawn guide rod can form a conductive path, so that electric current passes through, insulating shield main body, ground connection sliding sleeve and insulation barrier all are the materials with good insulation effect simultaneously, have good insulation effect, can guarantee safety.
This project is made exactly and a kind ofly should be guaranteed sealing, but the end shield earthing device of smooth opening again makes the sensor access reliable; Also satisfy the needs of conventional test from the function of end cap external ground.This end cap adopts polytetrafluoroethylmaterial material, and insulating property and physical strength and corrosion-resistant ageing resistance are stable.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
