Abstract
A power connector includes an insulative housing, a number of contacts retained in the insulative housing and a spacer fixed to the insulative housing. The insulative housing includes a mating surface, an end surface opposite to the mating surface and a plurality of passageways extending through the mating and the end surfaces. A depression and a cavity are recessed into the insulative housing from the mating surface and the end surface, respectively. Each contact includes a main portion received in corresponding passageway and a tail portion located in the cavity in condition that at least one side wall of the tail portion is exposed to the air for excellent heat dissipation.
Claims17
A power connector mountable on a circuit board for mating with a complementary connector, comprising:
- an insulative housing having a front surface, an end surface opposite to the front surface and a plurality of passageways extending through the front surface and the end surface, a depression being recessed into the insulative housing from the front surface;
- pairs of contacts received in the insulative housing along an insertion direction of the complementary connector, each contact having a main portion received in the corresponding passageway, a mating portion and a tail portion extending from opposite sides of the main portion and exposed to the air, each contact defining a cutout along a top edge and a bottom edge of the main portion;
- and
- a spacer received in the depression and defining a plurality of through holes communicating with the passageways for receiving the mating portions of the contacts, respectively, the spacer providing pairs of locking arms extending rearwards, each locking arm having a locking end retained in the cutout of corresponding contact to thereby limit a front-to-back displacement of the contacts.

A power connector for engaging with a complementary connector, comprising:
- an insulative housing defining a plurality of first passageways and a plurality of second passageway communicating with corresponding first passageways;
- and
- pairs of contacts received in the insulative housing, each pair of contacts composed by two separated contacts, each separated contact having a main portion assembled in the first passageway, a mating portion extending forwards within the second passageway, and a tail portion extending rearwards out of the insulative housing, each separated contact defining a pair of cutouts along a top and a bottom edges of the main portion;
- wherein a height of the first passageway in a cross-section view is larger than a height of the second passageway in a cross-section view;
- wherein the insulative housing comprises a first body portion and a second body portion assembled with the first body portion, and wherein the first passageways are defined through the first body portion and the second passageways are defined through the second body portion;
- wherein each separated contact has a pair of protrusion oppositely formed on the top and the bottom edges of the main portion and received substantially in the first passageway, and wherein each protrusion abuts against an inner faces of the first passageway;
- and
- wherein the first body portion of the insulative housing forms a pair of stoppers in the front of the first passageway, and wherein the protrusion of the contact is limited by the stopper along a front-to-back direction.
