The fixed form that specifically describes between each parts is: described connecting terminal block and insulation keeper are fixed by the fixing plug of terminal pin, described plug fixed housing and insulation keeper are fixed by the fixing plug of plug pin, reach the purpose of locking-type plug and terminals.
Specifically describe the structure of plug: plug comprises plug fixed mount, paired plug blades, spring leaf, steady pin, and paired plug blades is fixed by steady pin and plug fixed mount, and spring leaf is arranged between plug blades and the plug fixed mount, compresses plug blades.
The further structure of optimizing plug has two at two of plug blades and supports shoulder, equates that to the vertical range of the face of takeing on that supports to steady pin spring leaf is arranged on two in the gap of takeing on; The concrete structure of plug blades is stacked.
The structure of this plug is fixing reliable, patching stress point is that the center is stressed, two compresses, and the plug fixed mount is the metal manufacturing, when big current overload, plug construction has the self compensation function, clamping force increases with short circuit current, and spring leaf is a sheet band arcuate structure, and stressed is central point, so the spring structure fatigue resistance is good, the fixed structure of plug frame and spring has higher Mechanical Reliability simultaneously.
The needs that use according to reality can be provided with the paired plug blades of one deck in the plug fixed mount; The paired plug blades of multilayer perhaps is set in the plug fixed mount, and arranged perpendicular increases the contact area between bus and the main circuit connector between layer and the layer.
The beneficial effects of the utility model are: the spring anti-fatigue performance in the main circuit connector of this structure is good, and fixed mount intensity height is fixing reliable, patches reliably, and temperature rise is lower, patches with busbar combination stuck point to occur, and electric fault is difficult for taking place.
