Electrical connector

摘要

The present invention provides a vertical card connector (12) capable of preventing an undesirable flow of melted solder which destroys proper contacts and of removing a corrosion-causing acid gas. The vertical card connector includes an insulating housing (14) with a plurality of contact terminals (26) and a heat-resisting insulating resin film (28) covering the bottom surface (14b) of the housing. Each contact terminal has a solder tail (26b) extending through film. A slight gap (30a) is created between the heat-resisting film (28) and the bottom surface of the housing. The solder tail of the contact is inserted into a corresponding plated through hole (1a) and soldered there. The film (28) prevents a melted solder from flowing past the solder tail toward a contact beam of the contact at a time of soldering. A gas evolved from the solder escapes through the gap between the circuit board and the bottom of the housing.
