I. Product Overview

This low-voltage plug-in socket is manufactured using a combination of metal stamping terminals and plastic encapsulated injection molding technology. The internal conductive spring strips are made from high-elastic phosphor bronze stamping and bending, with the entire surface electroplated with gold, ensuring long-lasting stable low contact resistance. It can withstand tens of thousands of insertions and extractions without losing elasticity, preventing false connections and overheating issues. The exterior is wrapped with high-strength fiber reinforced nylon injection molding, offering excellent insulation properties, resistance to high temperatures and wear, and resistance to cracking and deformation, effectively preventing electric leakage hazards.

Socket head reserved standard plug cavity, compatible with mating male connector, one-piece molded shell with anti-dumb structure, can be accurately inserted into the equipment mounting hole, preventing movement and detachment during use; the bent metal pin at the tail can be directlywelding on the PCB circuit board, easy assembly and firm, suitable for installation in narrow spaces of various devices. The appearance, hole positions, and terminal arrangement can be modified according to the customer's overall structure requirements, with a 1:1 sample mold, and only after passing the pre-production electrical, plugging and pulling durability, and insulation voltage resistance tests.

Section 2: Core Highlights of Craftsmanship

1. Hardware terminal + one-piece plastic encapsulated injection molding, tightly combined and not separable
   Terminal pre-buried injection molding, no gaps or cracks, making it difficult for moisture and vapor to penetrate, excellent dust and moisture prevention, and prevents terminal oxidation and short circuits.
2. Phosphor bronze gold-plated elastic contact, stable holding and durable conductivity
   Double-claw gripping structure, fully conforms to conductor after plug insertion, maintains stable conductivity in vibration environment, and the gold-plated layer is anti-oxidation and corrosion-resistant.
3. High-temperature resistant and deformation-resistant nylon shell with fiber reinforcement
   Nylon material can withstand the temperature rise during small household appliance operation, will not soften and shrink after long-term heating, and the mechanical clips are not easy to break after repeated disassembly and assembly.
4. Tail-end bent welding tab design, convenient and firm PCB welding
   Multiple-point metal welding pads, sufficient soldering area, high tensile strength after welding, no terminal soldering failure due to cable pull.

Section 3: Optional Customized Raw Materials

1. Phosphor Bronze Gold Plated Terminal + PA66 Reinforced Nylon (Recommended)
   Excellent elasticity, stable conductivity, high-temperature and wear-resistant shell, widely used as the first choice for most small household appliances and industrial control equipment.
2. Beryllium copper terminal
   High fatigue resistance, specially designed for frequent plugging and unplugging of precision instruments.
3. PBT plastic shell:
   Higher heat resistance grade, for internal components of high-power heating appliances.
4. H62 brass nickel-plated terminal

Q&A on Procurement

Q1: Can the number of outlets be changed to create a 3-outlet or multi-pin socket?
A: Support, re-mold injection production for various hole positions from 1 to 8.
Q2: For the use of heating appliances with high ambient temperatures, what material is recommended?
A: PBT high-temperature plastic shell with thickened phosphor bronze gold-plated terminals, offers the best heat resistance and durability performance.
Q3: Can a sealed structure be made for slight waterproof and dustproof requirements?
A: Optimizing the injection mold structure can add waterproof lips to enhance the chamber's airtightness and dustproof, moisture-proof capabilities.
Q4: Can the insertion and removal force be adjusted?
A: Adjusting the bending angle of the spring clip and precisely controlling the thickness of the plate ensures a comfortable insertion and removal feel for the plug.
