Abstract
An electrical contact has a tab provided in passage which extends through the contact. The tab is dimensioned to provide a barrier, past which solder cannot flow. Consequently, as the contact is mounted to a printed circuit board, the tab prevents the solder from wicking from the mounting portion to the mating portion.
Claims11
An electrical terminal comprising:
- a mating portion and a mounting portion, the mounting portion has a passage which extends from proximate an end thereof toward the mating portion;
- a tab is provided in the mounting portion to completely block the passage, the tab is dimensioned to be slightly larger than the passage, such that as the tab is placed in engagement with the inner wall of the mounting portion, the tab will deform;
- whereby as the terminal has solder positioned on the mounting portion, the tab will prevent the solder from flowing through the passage from the mounting portion to the mating portion.
An electrical connector having a housing with contacts provided therein, the electrical connector comprising:
- terminals which extend in terminal receiving passages provided in the housing, the terminals have mounting portions which are configured to be soldered to a substrate, the terminals have passages provided therein which extend from free ends of the mounting portions;
- tabs are positioned in the passages of the terminals, the tabs cooperate with walls of the passages to provide barriers in the passages, the tabs are dimensioned to be slightly larger than the passages, such that as the tabs are placed in engagement with the walls of the passages, the tabs will deform;
- whereby as the electrical connector is soldered to the substrate, the tabs will prevent the flow of solder in the passages to positions beyond the tabs.
