Abstract: A small form-factor pluggable metal cage has two sidewalls, a sidewall cover, a top plate, a soleplate and a rear cover, which are made of a single piece of metal plate. Two types of legs extend from the cage, one being needle eye legs for extending through holes defined in a printed circuit board and the other being piggy legs abutting against the board. The needle eye legs define a shape of ellipse with a slot therein,whereby the needle eye legs serve as broad locks preventing the cage from disengaging from the board during the course of reflowing, while the piggy legs serve as standoffs for separating the cage from the board.

Abstract: A contact (1) for an electrical connector includes an elongated body portion (12) and a board-engaging structure (10) extending downward from a lower end of the body portion. The board-engaging structure includes a tail portion (14) which defines a vertical hole (19), enabling each of two sides of the tail portion to elastically deform when the contact is inserted into a hole (32) of a printed circuit board (30). Each of the two sides of the tail portion forms a locking arm (18) curved clockwise around the girth of the tail portion. Each locking arm has a contact surface (18a) of an outer limit thereof. Each contact surface is oblique such that an upper portion thereof extends further away from a longitudinal axis of the tail portion than a lower portion thereof does. Thus a considerable contact area is created between each contact surface and an inner wall of the hole in the printed circuit board.
