Abstract
Pressure-escape holes of a housing closed by a rubber plug and sealed by injection of molten filler are made to communicated with terminal reception rooms through notches. The pressure generated during injection of the filler, when the air in the pressure-escape holes expands can escape into the terminal reception rooms so as to prevent the rubber plug from being inclined, and prevent the filler from leaking outside the housing.
Claims3
A connector comprising:
- a housing;
- terminals mounted in said housing;
- gaps between said housing and said terminals;
- a filler, injected while in a molten state into said gaps to fill up said gaps such that said gaps are liquid-tight;
- a sealing member attached inside said housing to seal said housing so as to prevent said filler from leaking out from said housing when said filler is injected into said housing;
- ribs projecting inside said housing, said ribs provided in said housing to position said sealing member, and said ribs having pressure escape holes to prevent said sealing member from being displaced when or after said filler is injected into said gaps.
