CONTACT COMPONENTS • FIT • FINISH
Review drawing-defined metal contact components against the pin, socket, wire and housing in your design. Confirm material, machining, finishing and inspection scope before sample manufacture.

FOR CONNECTOR AND TEST-FIXTURE BUYERS
We machine drawing-defined contact components. Your mating parts, wire termination and finishing requirements determine what the sample must demonstrate.
01PCB test receptacle socket
Receiving bore, retention barb and tail geometry affect probe replacement and fixture assembly; keep internal edges free of loose burrs.
Supply mating probe and fixture details; agree bore and retention dimensions, plating scope and first-sample records.
02Pogo pin plunger contact
Tip profile, guide diameter and shoulders determine the mechanical envelope; they do not define the assembled spring-contact force.
Send barrel fit, travel envelope and finish requirements; define dimensional acceptance separately from electrical and cycle-life tests.
03Brass solder-cup socket contact
A clean mating bore and accessible solder cup serve different functions. Specify both ends and any surfaces excluded from plating.
Provide pin and wire sizes, plating specification and soldering access; agree finished dimensions and sample marking.
YOUR PROJECT. YOUR PRIORITIES.
Align engineering, sourcing and quality around a clear part definition before the quotation and sample review.
Identify locating diameters, insertion depths, shoulders and contact zones. Include the mating pin, barrel, insulator or wire interface, with the current drawing revision.
State the material grade, plating specification and any masked surfaces. Identify which fit dimensions apply after finishing and agree edge condition and cleanliness.
Agree dimensional and surface records for the machined component. Specify any electrical, spring-force or cycle-life test, its setup and the responsible party before it enters the quotation.

FROM THE CHENGSHUO PORTFOLIO / ONE PHOTOGRAPHED SERIES
Two source photographs show this brass component series. They establish the visible geometry, not a completed customer qualification or electrical-test result.
Separate locating diameters from contact zones. The case explains which material, finish and inspection requirements to agree for your own drawing.
