A composite foam metal contact piece

Abstract

The invention discloses a composite foam metal contact. The composite foam metal contact comprises an elastic porous polymer skeleton; the porous polymer skeleton is provided with a plurality of mutually communicated holes and is a three-dimensional net type perforated structure; and metal conductor layers are arranged in the communicated holes and on the surface of the porous polymer skeleton. When the composite foam metal contact disclosed by the invention is adopted to be electrically connected with a conductor, with the help of self elastic contact, welding is unnecessary; the composite foam metal contact is reliable to contact, assurable in performance, reusable and high in utilization rate; the equipment purchase cost is reduced; a single structure is simple to install and maintain; due to the large specific surface area, the skin effect of high-frequency signals can be effectively reduced; the composite foam metal contact is particularly suitable for high-frequency signal transmission; the production process is simple; and the consistency of finished products is good.

Description

technical field [0001] The invention belongs to a contact piece of an electrical connector, and relates to a compound foam metal contact piece. Background technique [0002] The existing electrical connector contacts are wired spring jacks, split slot jacks, crown spring jacks, twisted wire pins, pogo pins, spring probes, wool buttons, messy wire pins, etc. Wire spring jacks, split groove jacks, crown spring jacks, and twisted wire pins adopt a paired insertion structure, and the contact length is long. The electrical connector formed by it is large in size and high in docking height; the spring pin is composed of multiple Composed of three units, the structure is more complicated, and the installation and maintenance are more difficult; although the wool button and the messy thread pin are a single structure, their processing needs to go through winding, forming, shaping, shaping and other processes, and the production process requires high requirements.
