Zusammenfassung: | PURPOSE: To manufacture all necessary seals by a single operating process by charging first fluidized and then cured sealing material in corresponding passage system, even in the case of a complicated extended shape of a sealing system. CONSTITUTION: This casing for containing at least one electric printed circuit board comprises a casing member 1, a plug-in coupling member 4 for forming a constituting unit 2 having coupled electric printed circuit board 3, a seal 5, and another casing member 6. The member 4 has a step 22 called recess for receiving an edge range 21 of the member 6. A relatively complicated seal 5 is generated by the structure. This seal 5 is not formed of a premolded material but obtained by charging first fluidized and then curing material such as, for example, a polyurethane silicone mixture. |
