Embodiment
Accompanying drawing is the embodiment of the utility model.
Below in conjunction with accompanying drawing summary of the invention is described further:
The big electric current spacer assembly of a kind of bipolar DC its quiet all be to process with copper product into and out of line and swing arm with the electrician, form together through upper and lower insulation board and connecting plate.
With reference to Fig. 1, shown in Figure 2; The big electric current spacer assembly of a kind of bipolar DC, this device is made up of parts such as quiet input terminal, upper insulation plate, driving mechanism, travel switch, quiet outlet terminal, lower insulation plate, installation underframe, swing arm, macro-axis, compression spring, hinge seat, U type pull bar, connecting plate and insulated tension poles.Said quiet input terminal 1 is fixed in connecting plate 18 through supporting insulator 8, and quiet outlet terminal 21 is fixed in connecting plate 18 through supporting insulator 8 equally; Said connecting plate 18 is fixed together with lower insulation plate 6 through bolt and upper insulation plate 2; Said macro-axis 15 is installed between upper insulation plate 2 and the lower insulation plate 6, and an end of macro-axis 15 links together with the driving mechanism 3 that is installed on the upper insulation plate 2; On the said driving mechanism 3 travel switch 4 is installed; One end of said swing arm 11 is hinged through bearing pin 17 and hinge seat 10; Said hinge seat 10 is fixed together through bolt and installation angle steel 9; Said installation angle steel 9 is fixed on the quiet input terminal 1; The compression spring of installing on the said swing arm 11 12 is fixed on swing arm 11 through pull bar 13; One end of said pull bar 13 directly connects insulated tension pole 14, and insulated tension pole 14 is hinged through U type pull bar 16 and macro-axis 15; Said swing arm 8 is welded with moving silver contact 20 with the position of quiet input terminal 1 and quiet outlet terminal 5 overlap joints; Said quiet input terminal 1 is welded with quiet silver contact 19 with quiet outlet terminal 5 at corresponding site equally.
Shown in Figure 3, the position of swing arm and quiet input terminal and quiet outlet terminal overlap joint is welded with moving silver contact, and quiet input terminal and quiet outlet terminal are welded with moving silver contact equally at corresponding site.
Said bipolar quiet input terminal is fixed on the connecting plate through insulation column.
Said bipolar quiet outlet terminal is fixed on the connecting plate through insulation column.
Saidly quietly be welded with quiet silver contact into and out of the line terminals end.
