Embodiment
In order to make those skilled in the art person understand the utility model scheme better, and enable above-mentioned purpose of the present utility model, feature and advantage become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, 3, the utility model provides a kind of transformer low voltage conducting rod, comprise threaded rod 2, first binding post 4 and the second binding post 6 that structure is straight-bar, threaded rod 2 adopts the machine-shaping of copper material one, insulating sleeve 32 is provided with outside it, conduction and insulation property are all good, and the first binding post 4 and the second binding post 6 are separately positioned on the two ends of threaded rod 2, are respectively used to connecting coil lead-out wire and external high pressure line.The termination 10 that described first binding post 4 comprises terminal block 8 and is attached thereto, described termination 10 has the structure that cross section is " U " font, its openend is provided with socket 12, be positioned at socket 12 lower end and be provided with thread jack 14, described threaded rod 2 inserts and end after passing jack 14 is arranged with locking nut 16, and described threaded rod 2 is also arranged with check washer 18 between locking nut 16 and termination 10.
Described second binding post 6 comprises connection bolt 20 and flange 22, the end of described flange 22 connecting thread bar 2 and connection bolt 20, described connection bolt 20 is arranged with successively pressure-ray film 24, lead-in wire platform 26, line ball nut 28, clamp nut 30, the area that described lead-in wire platform 26 is contacted with the surface of pressure-ray film 24 is less than the surface area of pressure-ray film 24, also be provided with check washer 18 between described clamp nut 30 and line ball nut 28, described lead-in wire platform 26 is axially arranged with elastic 34 along it.
Based on above-mentioned structure, conducting rod of the present utility model, threaded rod 2 one end is locked by locking nut 16 after inserting the jack 14 of the first binding post 4, not easily loosens, solves the problem occurring joint looseness because of overheated; Simultaneously, the gage system of the second binding post 6 is optimized to of the present utility model contact from linear contact lay, lead-in wire is fixed by pressure-ray film 24 and line ball nut 28 under the location of elastic 34, the whole tiling that goes between is fixed on lead-in wire platform 26 table top, be face contact between the two, add contact area, reduce contact resistance, reduce heating, fundamentally solve the problem that transformer conducting bar pigtail splice is overheated; Can also loosen pad 18 by regulating clamp nut 30 to compress and then further compress lead-in wire, stable be fixed, and further prevents lead-in wire from loosening.
