The processing scheme of communication connector parts usually involves multiple links. The following are some common processing techniques and precautions for reference:

1. material selection

Metal Materials

Brass: low cost, good strength and elasticity, commonly used in contacts (such as pins, sockets).

Phosphor bronze: elasticity is better than brass, corrosion resistance is better, suitable for high reliability requirements of the scene.

Beryllium copper: excellent conductivity, strength and elasticity, but the price is higher, used for high-end or high-precision connectors.

Plastic materials

PBT (polybutylene terephthalate): good dimensional stability, high temperature resistance, commonly used in connector housings.

LCP (liquid crystal polymer): has excellent electrical properties and high temperature resistance, suitable for high-speed data transmission connectors.

2. processing technology

stamping forming

It is used to manufacture metal contacts (such as pins and sockets), and the metal plate is stamped into a required shape through a mold, with high efficiency and low cost.

Pay attention to control the stamping force and die accuracy to ensure the dimensional accuracy and surface quality of the contact.

injection molding

Used in the manufacture of plastic shells and insulators, plastic raw materials are injected into molds by injection molding machines.

The injection parameters (such as temperature, pressure, holding time) should be optimized to avoid defects such as bubbles and shrinkage cavities.

electroplating treatment

A layer of metal (such as gold, silver, nickel, etc.) is plated on the surface of the contact to improve conductivity, corrosion resistance and wear resistance.

The thickness and uniformity of the plating layer should be strictly controlled to ensure stable contact resistance.

ASSEMBLY AND ASSEMBLY

Assemble the contact, insulator, shell and other components into a complete connector, and ensure the matching accuracy and installation firmness of each component.

The use of automated assembly equipment can improve production efficiency and product quality stability.

3. quality control

Dimensional inspection

Use three-coordinate measuring instrument, caliper and other tools to detect the dimensional accuracy of the connector to ensure that it meets the design requirements.

Key dimensions (such as pin spacing, socket depth, etc.) are inspected with emphasis.

Electrical performance testing

Test the contact resistance, insulation resistance, voltage resistance and other electrical performance indicators to ensure the electrical reliability of the connector.

Use professional test equipment for automated testing to improve test efficiency and accuracy.

Insertion and extraction force test

Simulate actual use scenarios and test the insertion and extraction force of the connector to ensure smooth insertion and removal and reliable contact.

The insertion and extraction force shall be within the specified range to avoid poor contact or damage caused by too loose or too tight.

4. considerations

Design and process matching

In the design stage, the feasibility of the processing technology is fully considered to avoid processing difficulties or cost increase due to unreasonable design.

For example, the shape and size of the contact should be convenient for stamping, and the structure of the plastic shell should be conducive to injection molding.

mold development

The quality of the mold directly affects the accuracy and production efficiency of the product, and it is necessary to select a professional mold supplier for development.

Die accuracy, life and maintenance costs are important considerations.

Environmental Protection and Safety

Follow environmental regulations and select materials and processes that comply with RoHS, REACH and other standards.

Pay attention to safety protection during processing to avoid metal dust, plastic waste gas and other hazards to the environment and human health.

The above scheme can be adjusted and optimized according to specific product types and application scenarios. If more detailed process parameters or equipment selection suggestions are needed, further communication can be made with specific product requirements.
