Combining structure and the implementation of current existing plug terminal are once described in detail in detail below:
This type of structure is:
1, line end wiring combination: wire rod 4 successively through after nut 5, water proof ring 6, insulator 7, wire rod 4 and conductive copper core 16 are crimped together, then snap in lock nut 17 by the conductive copper core 16 after crimping, this is line end wiring combining structure and assembling mode, as shown in Figure 1.
2, plate terminated line combination: insulating body 18 is fixed together through water proof ring 6 and sheet metal component 1, then by two hold-down nut 19 link copper bars 3, finally copper busbar 3 and PCBA are linked together, this is line end wiring combining structure and assembling mode, as shown in Figure 2.
3, line end wiring is combined through plate terminated line combination on the screwed tight carried together, assemble complete, as shown in Figure 3.
The defect that above topology layout exists in practice:
1, when overall design limited space, implementation due to these terminal disassembly and assembly line end and plate end is separated by rotating screw thread, so cause client to dismantle and assemble extremely inconvenient (during rotational lock nut 17, hand and another terminal are interfered).
2, because the conductive copper core 16 of this terminal adopts machine work to produce, inner snap lock mode is complicated, and plastic cement die sinking part is too much, causes product cost too high.
3, the conductive copper core 16 adopted due to which is meticulous, be that the nut of M6 is connected with copper busbar 3, so overcurrent capability can only meet 80 Amps.Cannot meet design requirement.
