US 2017/0288353 A1 · ELECTRICAL CONNECTOR

Abstract

An electrical connector includes a plurality of connector units each having a base, a first pin, a second pin, and a soldering pad. The connector units may be linked together to form an array of connector units by a plurality of bridges that connect the bases of successive connector units. The bases of the connector units may be embedded in a plastic carrier material. The bridges and the portions of the bases to which the bridges connect may be positioned in the carrier unit such that they may be cut away from the rest of the electrical connector. The soldering pads and soldering ports of the first pins are configured to be soldered to a printed circuit board, resulting in two rows of electrically independent pins soldered to a single printed circuit board. A housing may be used to isolate the circuit board from forces applied to the pins.

An electrical connector comprising:

a plurality of connector units each having a base formed of a first arm and a second arm joined together by a cross member, each connector unit further having a first pin integrally formed with and extending from a first end of the first arm, a second pin integrally formed with and extending from a second end of the first arm, and a soldering pad integrally formed with and extending from a first end of the second arm, the first pin having a soldering portion and a blade portion;
and
a bridge integrally formed with and extending between the first arm of one connector unit and the second arm of another connector unit thereby linking the plurality of connector units together to form an array of connector units;
wherein the soldering portion and the soldering pad of each connector unit is configured to be soldered to a printed circuit board;
and
wherein the bridge and a portion of the first arm of each connector unit are configured to be cut out such that two rows of electrically independent pins are arranged on the printed circuit board.

A method for manufacturing an electrical connector assembly, the method comprising:

providing an electrical connector having a plurality of connector units each connector unit having a base formed of a first arm and a second arm joined together by a cross member, each connector unit further having a first pin integrally formed with and extending from a first end of the first arm, a second pin integrally formed with and extending from a second end of the first arm, and a soldering pad integrally formed with and extending from a first end of the second arm, the first pin having a soldering portion and a blade portion, and a bridge integrally formed with and extending between the first arm of one connector unit and the second arm of another connector unit thereby linking the plurality of connector units together to form an array of connector units;
embedding the base of each of the connector units in a plastic carrier such that a first surface of each connector unit base remains uncovered by the plastic carrier, and wherein the plastic carrier defines a plurality of apertures extending through a thickness of the plastic carrier, and wherein each aperture is positioned such that the bridge and a portion of the first arm of each connector unit are not embedded in the plastic carrier
removing the bridge and the portion of the first arm of each connector unit that are not embedded in the plastic carrier;
positioning the electrical connector embedded in the plastic carrier on a printed circuit board such that the soldering portion of each connector unit and the soldering pad of each connector unit are in contact with the printed circuit board to form a pre-soldering assembly;
and
passing the pre-soldering assembly through a reflow oven to solder the soldering portions and soldering pads to the printed circuit board.
