Abstract: An electrical contact of an electrical connector includes a mounting leg for being retained within a through hole of the printed circuit board wherein the mounting leg is tubular and is radially deformable to abut against an interior surface of the through hole. The mounting leg is radially thinned in thickness to confront the interior surface of the hole. The mounting leg is formed by rolling a metal plate with a C-shaped cross-section thereof. There are two thinned areas of the mounting leg, symmetrically located by two sides of the slit of the C-shaped cross-sectional configuration.

Abstract: An electrical contact includes a compliant tail defining a pair of opposite first main face and second main face, and a pair of opposite first side face and second side face linked between the first main face and the second main face. The opposite first side face and second side face are bulged for engagement with an interior surface of the corresponding through hole. A pair of first through holes and a pair of second through holes extend through both the first main face and the second main face. The first through holes are configured with an elongated configuration while the second though holes are located around two opposite upper and lower ends of the first through holes.

Abstract: A junction box includes a cable connecting box and a cover covering the cable connecting box. The cable connecting box includes an insulative block, a plurality of contacting foils retained in the insulative block and a plurality of diodes. Each diode connects with two neighborly contacting foils. The contacting foils are insert-molded with the insulative block. Based on thermal radiation properties of the plastic material is superior to that of the metal material, as the contacting foils transfer the heat to the insulative block, the insulative block would deliver the heat to the cable connecting box, then the heat would be delivered to the cover. Such that, the heat dissipates outside quickly from the junction box.
