Embodiment Construction

[0014] A pin for insertion into a plated through hole (PTH) of a printed circuit board is disclosed. In one embodiment, the needles are configured as power needles. However, those skilled in the art will appreciate that the pins may be configured for any purpose, including but not limited to signal pins. The needle includes a dual flex beam design with eye detail that allows the flex beams to move towards each other when the needle is inserted into the PTH. The PTH has known dimensions, for example, an internal plating diameter of 1.2 millimeters (1.2 mm).

[0015] For each PTH diameter, each needle is designed for a specific diameter of PTH to optimize certain parameters. For example, a dual-flex beam design (eg, compliant section) includes a pair of outwardly biased beam members with an elongated opening (or gap) between them. Additionally, each beam has a thickness. Typically, the beam thickness and elongated opening are optimized relative to the PTH diameter in order t...

Abstract

A compliant pin for insertion into a hole having a diameter and a plating therein is provided. The pin includes a compliant portion including a pair of outwardly biased beam members having an elongate opening therebetween. Each beam has a beam thickness. The beam thickness and the elongate opening are optimized with respect to the diameter such when the pin is inserted into the hole that the compliant portion is limited to a predetermined level of plastic deformation and the compliant portion is limited to a predetermined level of damage imparted upon the hole plating.

Description

technical field [0001] The present embodiments relate to electrical contacts, and more particularly to press fit electrical contacts for plated through holes. Background technique [0002] Press-fit pins are used as solderless permanent connections for electronic components that rely on a hermetic fit between the terminal contacts and plated through-holes (PTHs) of a printed circuit board. Previously, these press-fit sections were connected using solid non-compliant pins. This method was found to be unreliable due to excessive damage to the PTH. The compliant terminal interface was developed to provide a spring-loaded interface where forces are absorbed through the terminal contacts rather than the PTH. [0003] Compliant pins typically include a press-fit portion that attaches to a lead frame for a solderless connection to a printed circuit board. The press fit part is used to squeeze the electrical contacts with the PTH of the printed circuit board. By electroplating, ...
