Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As depicted in figs. 1 and 2, the utility model discloses a kind of insulated shielding cover, for covering the lead-in wire fixed body going between and be positioned at this lead-in wire one end, wherein, lead-in wire is fixed contact copper coin and the lead-in wire of lead-in wire vertical-type disconnecting link, and this lead-in wire fixed body is used for lead-in wire being connected to electric pole end or iron load.Insulated shielding cover comprises insulating bar 1 and more piece insulating sublayer mask 2, more piece insulating sublayer mask 2 is detachable connection successively along wire length direction, insulating bar 1 one end is connected with wherein a knot insulated shielding cover 2 is detachable, for being held up by the more piece be connected insulating sublayer mask 2 and being located on lead-in wire and lead-in wire fixed body.In the present embodiment, insulating bar 1 one end is connected along vertical leads direction with the insulating sublayer mask 2 for covering the fixed body that goes between.Concrete syndeton is, insulating bar 1 end is provided with external screw thread, and above-mentioned insulating sublayer mask 2 is provided with the permanent joint 3 for being threaded with insulating bar 1, and this permanent joint 3 structure is not unique, and concrete structure can with reference to shown in figure 8.
Further, continue composition graphs 1 and Fig. 2, in order to avoid the wire in bird's nest falls on lead-in wire between two adjacent knot insulated shielding covers 2, therefore the correspondence socket of the end of two knot insulated shielding covers 2 adjacent in the present embodiment, make between two insulating sublayer covers as forming seamless link.Insulating sublayer mask 2 in the present embodiment comprises thickness and is all not less than the side cover plate 5 that the lamina tecti 4 of 3mm and two pieces are located at the both sides of lamina tecti 4 relatively, namely to be right angle U-shaped in the cross section of more piece insulating sublayer mask 2 in its closure vertical, specifically as shown in Figure 8., in order to realize the socket of two adjacent knot insulated shielding covers 2, can corresponding increase or reduce the width of lamina tecti 4, the width from the insulating sublayer mask 2 for covering lead-in wire fixed body of each knot insulated shielding cover 2 in the present embodiment reduces gradually.In addition, in the present embodiment, the side cover plate 5 of each knot insulated shielding cover 2 be hypotenuse for the side be connected with lamina tecti 4, its side towards lead-in wire fixed body one end is also hypotenuse, and be obtuse angle towards side and the side cover plate 5 of lead-in wire fixed body one end for the angle between the side that is connected with lamina tecti 4, like this, its socket area can be increased when two knot insulated shielding covers 2 socket-connect, and then strengthen the stability of socket.After more piece insulating sublayer mask 2 is connected, as shown in Figure 1, its end face is an inclined-plane, and more piece insulating sublayer mask 2 highly reduces all gradually from the insulating sublayer mask 2 for covering lead-in wire fixed body, specifically can with reference to figure 1 and Fig. 2, to alleviate the weight of each knot insulated shielding cover 2.Namely, more piece insulating sublayer mask 2 size and weight from the insulating sublayer mask 2 be connected with insulating bar 1 reduce all gradually, like this can not only be more laborsaving when supportting act shielding portion, also more easily ensure the stability of insulating sublayer mask 2 and gage lap simultaneously.Certainly, from one that is connected with insulating bar 1 sub-insulated shielding cover 2, the size of each knot insulated shielding cover 2 and weight also can subtract greatly all gradually, and namely, each insulating sublayer mask 2 is width and increasing highly gradually on the direction near insulating bar 1.Certainly, other forms are also feasible, as long as can be socketed each other, can cover lead-in wire and lead-in wire fixed body.
The first connector 6 and the second connector 7 that insulating sublayer mask 2 top its two ends place contiguous are respectively equipped with, two adjacent knot insulated shielding covers 2 all realize detachable connection by the first connector 6 of respective outer side edges and the second connector 7.
Wherein, the structure of the first connector 6 and the second connector 7 is not unique, discloses three kinds of different structures in the utility model, specific as follows:
Embodiment one: as shown in Figure 3 and Figure 4, the first connector 6 has connecting hole 8, and the first connector 6 structure is not unique, can be a plate and can be a Metallic rod yet; Second connector 7 comprises the mounting panel 9 be located on insulating sublayer mask 2 and the collar 10 be located on mounting panel 9, specifically mounting panel 9 can be arranged with the form of its plate face parallel lead wire length direction, then on mounting panel 9, offer an installing hole, the collar 10 is located in installing hole; Or directly the collar 10 is fixed on mounting panel 9 and also can.Wherein, the collar 10 has a gap 11, to stretch in the connecting hole 8 of the first corresponding connector 6 by its gap 11 for making this collar 10 and realize clasp joint.
Embodiment two: as shown in Figure 5 and Figure 6, the first connector 6 is identical with embodiment one structure, has connecting hole 8 equally; Second connector 7 comprises the mounting panel 9 be located on insulating sublayer mask 2 and follows closely 12 for the U-shaped river of the first connector 6 clasp joint with adjacent insulating sublayer mask 2.Particularly, mounting panel 9 is arranged with the form of its plate face vertical leads length direction, then two circular holes are offered at mounting panel 9 towards the side correspondence of above-mentioned first connector 6, after U-shaped river nail 12 and the connecting hole 8 phase clasp joint of this first connector 6, it is interior and fixed by nut that its two ends are arranged in above-mentioned two circular holes respectively.
Embodiment three: as shown in Figure 7 and Figure 8, the first connector 6 is identical with embodiment two structure with embodiment one; Second connector 7 comprises is located at the mounting panel 9 on insulating sublayer mask 2 and the U-shaped pipe 13 for the first connector 6 clasp joint with adjacent insulating sublayer mask 2.Particularly, mounting panel 9 is provided with the connector 14 for coordinating grafting with the two ends of U-tube 13 towards the side of the first connector 6, connector 14 in the present embodiment is for being vertical at the short pipe on mounting panel 9, and be provided with corresponding with on U-shaped pipe 13 of this connector 14 inserts at the two ends of U-tube 13 through hole wearing fixing pin 15 after in corresponding connector 14, thus U-tube 13 is fixed on connector 14.
Owing to being clasp joint between the first connector 6 and the second connector 7, therefore two adjacent knot insulated shielding covers 2 can be turned an angle mutually, better to cover lead-in wire and lead-in wire fixed body, the scope of application is wider, specifically can with reference to shown in figure 1, Fig. 9 and Figure 10.
Adopt insulated shielding cover of the present utility model can prevent the wire be mingled with in bird's nest material from directly falling on exposed isolating switch lead-in wire and lead-in wire fixed body when extracing bird's nest, drop on electric pole or iron load on cause line fault, make operating personnel can extract bird's nest safely when overhead wire is charged.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection range of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection range, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection range of the present utility model.
