insulation piercing connector is a commonly used piercing connector product in the electronics market, but users often confuse ipc connector with plug-in pins. In fact, there are technical differences between them. In this article, Xinpengbo Electronics mainly shares the technical system differences between ipc electrical connectors and plug-in pins!

1. Differences in structural design between cable piercing connector and pins:

1. cable ipc connector

Using cylindrical metal sleeve structure (diameter 4.0mm or 4.8mm)

Built-in elastic contact piece design (commonly using phosphor bronze material)

Standard protective shell (meets IP44 protection level)

Typical representative: Schuko socket (CEE 7/4 standard)

2. Pin assembly

Solid cylindrical structure (usually 2.5-4.0mm in diameter)

The surface is mostly nickel-plated or gold-plated

No protective shell (need to be used with sockets)

Common types: DIN pins, banana plug pins

2. Comparison of electrical characteristics between electrical piercing connector and pins:

Parameter insulation connector Pin assembly Rated current 10A/16A/32A three gears usually ≤5A (except for special designs) Dielectric strength 2000V/1min (IEC 60664) 500V DC test contact resistance ≤3mΩ (new state) ≤10mΩ (unloaded state)

III. Application scenarios of insulation piercing and pins:

1. Advantage scenarios of socket connectors

Fixed installation occasions (wall/distribution box)

Working conditions that require frequent plugging and unplugging

Wet environment (bathroom/outdoor)

High safety requirements (kindergarten/hospital)

2. Application areas of pins

Internal connection of instruments and meters

Temporary test circuit construction

High-density PCB board connection

Customized equipment interface (need to be used with the mother seat)

IV. Differences in safety specifications between European socket connectors and pins:
