Fuzzy button

Abstract

The invention discloses a fuzzy button made by random winding and filling of metal wires. The random winding is better for transmission of high-frequency signals, the size is smaller, contact is more reliable, the randomly wound wires are suitable for connecting any metal surface (pad) to a pad, and no welding or crimping is required. The fuzzy button has the advantages that high signal transmission rate allows signal frequency to be higher than 20 GHz; compressed interconnection needs no welding or crimping; with low mounting speed, the fuzzy button is applicable to an LGA (land grid array) integrated circuit socket and to perpendicular interconnection between PCBs (printed circuit boards); the problems in PCB via-holes and surface mount welding are solved; weld-connecting is avoided, and mounting, upgrading and system maintenance are facilitated; connections range from 1 to 7000; the fuzzy button is available for contact spacing as low as 1mm or higher.

Description

Technical field [0001] The invention belongs to an electrical connector contact piece, and particularly relates to a messy wire pin. Background technique [0002] At present, the existing reliable and stable electrical connector contacts are wired spring jacks, split slot jacks, stranded wire pins, crown spring jacks, spring pins, etc., and their common feature is that they are suitable for transmission frequency Low signal, and when transmitting high-frequency signals, due to the propagation characteristics of high-frequency signals and the limitations of the structure and material of the above contact parts, the signal propagates on the surface of the part, increasing the signal path length, resulting in signal distortion and The loss increases sharply; at the same time, the contact length of the above contacts is relatively long, and the electrical connectors formed by them are large in size and high in docking height, which is no longer suitable for the application requiremen...

Problems solved by technology

[0002] At present, the existing reliable and stable electrical connector contacts are wired spring jacks, split slot jacks, twisted wire pins, crown spring jacks, pogo pins, etc. Their common feature is that they are suitable for transmission frequency When transmitting very high-frequency signals, due to the propagation characteristics of high-frequency signals and the limitations of the structure and material of the above contacts, the signal propagates on the surface of the part, increasing the length of the signal path, resulting in signal distortion and The loss increases sharply; at the same time, the contact length of the above contacts is longer, and the electrical connector formed by them is bulky and has a high docking height, which is not suitable for the application requirements of increasingly dense electronic equipment components and shrinking chassis; moreover, the above contacts The termination methods used are generally fixed methods such as crimping, welding, wrapping, and screw connections, which are extremely inconvenient for equipment installation, commissioning, and maintenance.
