Embodiment 1
[0028] see Figure 1-Figure 5 , an inner core positioning piece for overhead insulated cables in the figure, including a plurality of positioning frames 1, the positioning frames 1 are provided with connecting holes 2, and the connecting holes 2 are inserted with connecting rods 3 , and also includes a plurality of connecting plates 4 fixed on the outer end of the positioning frame 1 and a plurality of filling sleeves 10 installed on the outside of the positioning frame 1. The outer ends of the plurality of connecting plates 4 are fixed with positioning plates 5, one of which is A T-shaped groove 6 is opened in the positioning plate 5, and a clamping member 7 is installed at the bottom of the positioning plate 5, and elastic connecting members 8 are installed on the outer side of the positioning frame 1 corresponding to a plurality of positions of the positioning plate 5. And a plurality of the positioning plates 5 are sheathed with fastening strips 9, and the two ends of the ...
Embodiment 2
[0043] see Figure 5 and Image 6 , this embodiment further describes Example 1. In the figure, the outer side of the positioning plate 5 is provided with a fastening groove 15, and the fastening strip 9 is sleeved in the fastening groove 15. At the same time, the inner wall of the fastening groove 15 is The depth is consistent with the thickness of the fastening tape 9;
[0044] It should be noted that: the fastening groove 15 opened on the outer side of the positioning plate 5 with the same thickness as the fastening tape 9 can satisfy the stable binding of the fastening tape 9 without affecting the subsequent wrapping of the wrapping tape.
Embodiment 3
[0046] see Figure 8 , this embodiment further describes other embodiments, the elastic connector 8 in the figure includes a limit rail 16 fixed on the bottom of a plurality of positioning plates 5 and the clamping plate 11, the outer side of the positioning frame 1 corresponds to the limit An elastic piece 17 is installed at the position of the rail 16 .
[0047] It should be noted that: when the positioning plate 5 is pulled by the tightening belt 9, the positioning plate 5 can be moved down, and the elastic sheet 17 will be squeezed at this time, so that the elastic sheet 17 is retracted, and at the same time the positioning plate 5 is moved down, and the The clamping plate 11 can be counteracted, so that the clamping between the clamping plate 11 and the tightening belt 9 is more tightly and stably.
[0048] It is worth noting that: the elastic sheet 17 includes an inclined conical plate 19, and one end of the conical plate 19 is fixed to the outer wall of the positioning...

Abstract
The invention discloses an inner core positioning piece for an aerial insulated cable, relates to the technical field of cable inner core positioning, and solves the problem of poor positioning effect when an existing cable chip is wrapped, the inner core positioning piece comprises a plurality of positioning frames, connecting holes are formed in the positioning frames, and connecting rods are inserted into the connecting holes; the connecting plates are fixed to the outer ends of the positioning frames, the filling sleeves are installed on the outer sides of the positioning frames, positioning plates are fixed to the outer ends of the connecting plates, a T-shaped groove is formed in one positioning plate, a clamping piece is installed at the bottom of the positioning plate, elastic connecting pieces are installed on the outer sides of the positioning frames, and the outer sides of the positioning plates are sleeved with fastening belts. The multiple inner cores are limited through the multiple designed positioning frames, the multiple inner cores are not prone to being scattered or twisted together in a staggered mode after being limited through cooperation of the fastening belt and the positioning plate, meanwhile, the designed filling sleeve can be attached to the inner cores along with the positioning plate, and subsequent wrapping of the winding belt is more round.
Description
technical field [0001] The invention relates to the technical field of cable inner core positioning, in particular to an inner core positioning sheet for overhead insulated cables. Background technique [0002] Aerial cables (full name overhead insulated cables) are overhead conductors equipped with insulating layers and protective sheaths. They are produced by a production process similar to that of cross-linked cables. Way. Aerial cables can be divided into hard aluminum wire structure, hard drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure and self-supporting three-core textured structure according to their different structures (the wire core can be hard aluminum or aluminum alloy. hard copper wire) etc. It has the main characteristics of high power supply reliability, good power supply safety, convenient erection and maintenance, and reasonable economy. Its main technical parameters include weather resistan...
