る。As is apparent from FIG. 3, there is a space 36 between the contact blade 34 a of the terminal 34 and the inner surface of the terminal receiving passage 22. This applies to all terminals 34. Without any wicking prevention mechanism, the solder or flux could lead to terminal 34 due to capillary action.
This flows into the space 36 along the contact blade 34a, causing problems such as the terminal 34 not functioning or a short circuit occurring between the terminals 34. Conventionally, to solve this problem, extra parts are provided to block the terminal receiving passages, the terminal receiving passages are filled with extra material such as epoxy, or a separate barrier such as a plastic film or aluminum strip is used. Extra parts or materials such as installations are mainly used. In general, according to the present invention, the solder material may flow along the terminals 34 into the terminal receiving passages 22 to cause wicking only by thermally fixing the housing 12 so as to close the terminal receiving passages 22 at the open ports 24. Easily prevented.

The excess or material of the ribs 40 of 2 is heat set like 40a to completely close the open mouth 24, thereby completely closing the terminal receiving passage 22 at the terminating end 16 of the housing 12. Therefore, the heat-fixed portion 40a of the housing 12 forms a barrier to prevent a substantial amount of solder or flux material from flowing along the terminals 34 into the housing 12 and causing wicking.
In addition, the heat-fixed portion 40a also serves to hold the terminal 34 in place in the terminal receiving passage 22 of the housing 12.
