Causal Understanding and the Scientific Division of Labor: Experiences and Prospects of Life Course Research in Germany and beyond

A battery power connector comprises a plastic block with a pair of raised pedestals at opposite ends of one side that fit through rectangular cutouts in the rear panel of a RETMA-rack chassis. A pair of bolt holes in the rear panel between the cutouts and a matching pair of bolt holes between the raised pedestals in the plastic block allow for a mounting that is electrically isolated for positive and negative, and conductive for ground in the middle. Inside the chassis, a double-sided printed circuit board is bolted to the back of the plastic block with three pairs of bolts, one pair each for positive, ground, and negative battery cable connections. A threaded backing plate is provided on the outside to receive each of the three pairs of bolts, one for each positive, ground, and negative battery cable connection. A two-hole battery-cable lug is then bolted over each threaded backing plate and is held tightly with two nuts and lockwashers each. The printed circuit board provides several wire lugs inside for both battery potentials to be wired to individual on-off power control modules.
