01 Connectors 

A connector is a component used to connect electronic devices or circuits, and a pin is a part of a connector that is inserted into the connector's socket to establish a circuit connection. Pins are usually made of metal materials and have conductive properties. The application range of pins is very wide, and the following are some common application areas:

· Electronic equipment: Pins are often used on circuit boards of electronic devices to connect various electronic components, such as integrated circuits, resistors, capacitors, etc.

· Communication equipment: Pins are used to connect cables of communication equipment such as telephones, mobile phones, modems, etc. to achieve signal transmission.

· Automotive electronics: Pins are used in automotive electronic systems to connect various sensors, control modules, and displays, etc.

· Industrial equipment: Pins are widely used in industrial automation equipment to connect sensors, actuators, controllers, etc.

· Computer hardware: Pins are used to connect computer hardware components, such as memory modules, expansion cards, data cables, etc.

02 Process Difficulties and Requirements for Connector Pins

·Precision requirements: The manufacturing of pins requires high-precision processing and assembly to ensure that the pins can be accurately inserted into the sockets and establish reliable circuit connections.

·Conductive properties: As the conductive part of the circuit, the pins need to have good conductive properties to ensure the stability and reliability of signal transmission.

·Durability: The pins need to have high durability and be able to withstand frequent plugging and unplugging operations without damage or failure.

·Corrosion and oxidation resistance: Pins are usually exposed to the external environment and require anti-corrosion and anti-oxidation materials or surface treatments to extend the service life of the pins.

·Connection stability: The pins need to be tightly connected to the sockets and have good mechanical stability to avoid loosening or disconnection of the pins during use.

03 Connector pin fixing method

1. Connector pin press-in type: The pin is fixed by forced pressing.

· The pin is easy to install, and the insulated wire does not need to be stripped, ensuring good electrical connection without damaging the wire.

· No need to withdraw the wire, saving cable investment.

· No need to cut the main cable, and the branch point can be made at any position of the cable.

· Low cost and small installation space requirement.

· The connector is fully insulated, and the cable branch can be made without stripping the cable insulation layer.

2. Epoxy type connector pin: After the insulator and the shell are punched, the pin is fixed with epoxy resin.

· Strong chemical resistance, acid resistance, alkali resistance, and organic solvent resistance.

· Low molding shrinkage, good dimensional stability, and low probability of cracking.

· Excellent mechanical properties and heat resistance.

· High bonding strength, especially suitable for products with plug-ins and plastic shell packaging of coils and electronic devices.

· It has excellent electrical properties and can be used as an insulating material for high frequency and high voltage. Its arc resistance and surface leakage resistance are stronger than general insulating materials.

3. Connector pin point riveting: Press in and then point rivet the shell to fix the pin.

·Simple structure, high reliability, a cost-effective permanent fixed assembly method.

·The assembled metal parts are firm, tight, stable, and have high impact resistance, corrosion resistance, impact resistance and weather resistance.

·The processing process is vibration-free, pollution-free, noise-free, environmentally friendly, energy-saving, fast, efficient, high-quality and beautiful.

·Multi-point riveting fixation is possible without adding any adhesives, solvents, fillers and fasteners, low energy consumption, compact equipment and small footprint.

04 Advantages of laser in fixing pins

·When using epoxy resin to fix the pins. The role of pin roughening is to increase the roughness of the fixed part to better fix the pins to prevent loosening and rotation.

·Using the 150W green light produced by our company, a product can be roughened within 3.6s, which is more efficient in roughening the pin fixing surface.

Copper absorbs green light better, generates less heat and has better effect, and will not oxidize due to excessive temperature during texturing.

·The roughness can be Ra>5um and relatively uniform.

·Average marking depth <6um

05 High-power quasi-continuous green fiber laser

·Good beam quality: The laser beam produced by the green fiber laser is of high quality, small spot and high beam quality, which is suitable for precision machining and high-precision applications.

·High energy efficiency: Compared with traditional gas lasers, green fiber lasers have higher energy efficiency, lower energy consumption, energy saving and environmental protection.

·Strong stability: Green fiber lasers have good working stability, stable beam quality and power output during operation, and are suitable for long-term continuous operation.

·Easy to integrate: Green fiber lasers are small in size and light in weight, which are easy to integrate into various equipment and are widely used in medical, communication, material processing and other fields.

·Tunability: The wavelength of green fiber lasers is usually around 532 nanometers, and the wavelength can be fine-tuned by adjusting the device parameters to meet the needs of different applications.

·Long life: Green fiber lasers usually have a long life, low maintenance cost and good economy.
