Electrical circuit unit with moisture sealed plug-in connectors

DETAILED DESCRIPTION It is an object of the present invention to shorten the conducting paths required on the circuit boards and to reduce the number of circuit board connectors.
Briefly, a divided plug body is used in the circuit unit so that each of the plug body parts can be plugged into the mating plug connection parts related thereto at the same time.
Each plug body part is mounted on one of the circuit boards which carries all the components which are to be connected thereby.
In this way the apparatus as a whole can be made smaller and at lower cost.
There is the further advantage that the unit is less vulnerable to disturbing electromagnetic fields.
It is particularly useful for the parts of the plug body to be releasably connected with each other, or at least that there be a releasable connection of one part with another part that receives it.
That makes for simple and economical assembly.
In addition, the parts of the plug body can be sealed against each other in order to make an arrangement for sealing out moisture and dirt, through which the likewise sealed plug connection prongs lead outward from the casing of the circuit unit.
