Where Do Contacts Contact?
Although electrical contacts appear to have a large surface area,
only a small portion of that area actually touches the mating part,
because any metal surface — no matter how finely polished or
ground — is never perfectly flat or smooth.

Mating summits or asperities

summits or high peaks
(asperities).
The

large, ample area, actually
conducts current through no
more than three lines of
contact in this example.
The sliding contact, when
spring loaded, conducts
current through an entire line
of contact.

What Makes A Good Connector?
The termination can make the difference between good and poor
connector continuity. This hypothetical example of “good” and
“poor” continuity shows how power loss can seriously impair the
efficiency of an EV. Important are two points of resistance:
1. Rc, the central contact resistance.
2. Rw1 the resistance at two terminations.
A typical sliding connector carries 175A, but when the termination
resistance Rw, rises because of faulty design or assembly, total
resistance rises, too. (See table). Using the basic relationship for
DC power,
P= (I x R) (I) = I²R
The “good” conductor dissipates, or loses,
P = (175)² (0.00004) = 1.225W
The “poor” conductor loses,
P = (175)² (0.00202) = 61.8W
