定义
Connection holes are precisely engineered apertures in electrical busbars designed to facilitate reliable electrical connections through bolted or clamped interfaces. These holes maintain proper alignment, ensure uniform contact pressure, and provide mechanical stability while accommodating thermal expansion and electrical load variations in power distribution applications.
工作原理
Connection holes enable electrical continuity by providing mounting points for conductors, allowing current to flow through bolted or clamped connections while maintaining mechanical integrity through precise hole positioning and sizing that distributes stress evenly across the busbar surface.
材料
Typically match busbar material: Copper (C11000C10100)Aluminum (60616101)or copper-aluminum compositesmay include plating (tinsilvernickel) for corrosion resistance and improved conductivity.
Burr Height
≤ 0.1mm maximum
Edge Distance
Minimum 1.5× hole diameter from busbar edge
Hole Diameter
M6-M20 (standard metric) or 1/4"-3/4" (imperial)
Hole Tolerance
±0.1mm for precision applications
Pitch Distance
2.5-3× hole diameter between centers
Surface Finish
Ra ≤ 3.2μm for optimal contact
标准
ISO 12944-5DIN 43673IEC 61439-1ASTM B187

常见问题

What is the primary purpose of connection holes in busbars?

Connection holes provide secure mounting points for electrical conductors, ensuring reliable current transfer through bolted or clamped connections while maintaining mechanical stability and proper alignment in power distribution systems.

How are connection holes typically manufactured?

Connection holes are precision-drilled using CNC machining, laser cutting, or punching processes, followed by deburring and surface finishing to ensure smooth edges, proper dimensions, and optimal electrical contact surfaces.

What factors determine connection hole spacing and size?

Hole size and spacing are determined by bolt diameter, electrical current capacity, mechanical load requirements, thermal expansion considerations, and applicable standards like DIN 43673 or IEC 61439 for safety and performance.
