Terminal piece sealing structure

A seal structure for an electric device, comprising:

• an electrically insulating housing having a through hole which extends through a bottom wall thereof, and a lateral slot extending from a side surface of said housing into said bottom wall, said lateral slot being in communication with said through hole;
• an electrically conductive lead portion which passes through said through hole and said lateral slot;
• and
• a sealant disposed in said lateral slot, said sealant surrounding a section of said lead portion which is disposed in said lateral slot.

A method for sealing an electric device having a terminal including an electrically conductive lead portion in an electrically insulating housing having a bottom surface with a through hole therein and a side surface having a lateral slot therein, comprising the steps of:

• a) forming said through hole in said electrically insulating housing, said through hole extending from said bottom surface of said housing;
• b) forming said lateral slot in said side surface of said housing such that said slot and said through hole are in communication;
• c) inserting said electrically conductive lead portion into said through hole and through said slot;
• d) injecting sealant directly into said slot;
• and
• e) curing said sealant.
