Circuit board connector and method of assembling it

摘要

A PCB connector (10) has a housing (11) with a receptacle (14) that has a rear wall (12). The rear wall (12) has through holes (30) that provide communication between the inside and the outside of the receptacle (14). Recesses (31) are formed at receptacle ends of the through holes (30). Terminal fittings (20) are introduced through the through holes (30) from the outside of the housing (11). Chips (34) produced by the abrasion of the terminal fittings (20) and the inner walls of the through holes (30) stay in the recesses (31) and do not interfere with a mating connector.
