What is a sleeve terminal (pin holder)?

Strengths of sleeve terminals (pin holders)

Our Sleeve Terminals are processed into a pipe shape by making holes in the wire using our unique heading technology cultivated from many years of experience.
In addition, our processing machines are designed and manufactured in-house to secure highly accurate product manufacturing.
Sleeve Terminals are generally manufactured by drilling holes, but it takes time and effort to process.
However, with our heading technology, we are able to increase the processing speed per single product, what makes cost reduction possible.

Manufacturing process of sleeve terminal (pin holder)

➀ Wire-cut → ② Drilling (processed into a pipe) → ③ flanges modeling

Examples of Sleeve Terminal (Pin Holder) usage

The Sleeve Terminal is used to connect Press-fit Pins and terminal pins to boards that cannot be drilled. (The sleeve stands on the board and functions like an “alternative” hole.)
Sleeve Terminals are used for IGBT modules and substrates for power semiconductors such as SiC modules.

Examples of adoption of power semiconductors such as IGBT / SiC modules

Power semiconductors such as IGBT / SiC modules are used in various fields such as inverters for HEVs / EVs and trains, UPS (uninterruptible power supply), and home appliances (air conditioners, etc.).

Advantages of Sleeve Terminals (Pin Holders)

Since the sleeve terminals (pin holders) perform the same function as the through hole of the board, the soldering of the inner pins (e.g. Press-fit Pin) to the board is not required.

Since we produce the tubular terminals ourselves, we are able to control the tolerance of the terminal’s inner diameter very precisely.

Sleeve terminal (pin holder) and press-fit terminal

When using our press-fit terminals, soldering with the mating board is not required.

About the press-fit terminal

• Our press-fit terminals can be processed from wire rods.
• The production of press-fit terminals made from wires reduces stamping die costs, material loss, and plating costs compared to the processing from a strip.
• The press-fit section becomes needle-eye type.

Sleeve terminal (pin holder) and automatic insertion machine

We also sell an automatic insertion machine (FINESERT) that automatically inserts a pin into a Sleeve Terminal that stands on a power semiconductor substrate such as an IGBT module.

When using the automatic insertion machine, the press-fit pins will be delivered as end-to-end pins.
