Are there any PCB connectors that carry high voltage?
My application will have low current (mA) but high voltage lines. High voltage will arriving from external source using banana jacks on the case. I am looking for an example in which someone uses PCB connectors (i.e., terminal blocks) that carry high voltage (e.g., 5KV). But I’m not having success.
Is it safe to use 2.5kv connectors?
With BV = 2.5KV for me it’s clear that bringing the two connectors so close to each other the material will break. Maybe I’m wrong. I know the creepage and clearance techniques, but if I understood well it’s referred to the sheet material and the copper over it, that has its own breakdown voltage/mil. But what about connector material?
How to get minimum distance between two connectors?
Whereas trace and pad spacing literature suggests for certain kind of material to divide nKV/30cm to obtain safety distance between pads or traces with high voltage differences, what can be applied to the gap of connectors? How to get the minimum distance between two connectors with higher voltage level than its breakdown voltage?
What should be the voltage between two plastic connectors?
Plastic can be >10kV/mm. The highest level of indoor contamination of residential humid dust on the best dielectric reduces to about 0.3kV/mm so 0.2kV/mm became the standard. There exist various levels of dust& RH vs withstanding voltage in between.
Why do PCB connectors have strain relief in them?
Each connector has its own way of protecting itself, called strain relief. This helps to keep all of the sensitive metal contact pieces inside from breaking when jostled around by human hands and other mechanical vibrations. Now let’s say you do manage to capture and kill one of those dangerous connectors out in the wild. What now?
How does a press fit connector attach to a PCB?
After the PCB is fixtured and the connector positioned and aligned on top of it (or vice versa), the press is activated. Any type of press (toggle, hydraulic, pneumatic and servo-electric) may be used, so long as it has the proper tooling and its ram imparts the required force.
How does a PCB connect to a cable harness?
The PCB would be designed such that the header pin traces would electrically connect to corresponding plated through holes, and then soldered to the bare conductors of the cable harness. Next, the intermediary PCB must be electrically insulated and encapsulated for strength.
