Sleeve (Pin holder, Terminal holder)

This product is manufactured and sold by FINECS.

What is a sleeve terminal (pin holder)?

What is a sleeve terminal (pin holder)?

The sleeve terminal (pin holder) is a tubular terminal to support the pin that’s inserted into it. Sleeve terminals (pin holders) are made by crimping wire rods into a tubular shape.
* Depending on the terminal’s shape, there may be patents existing. Therefore, a patent check is necessary.
* Plating options: Nickel plating, gold plating, no plating.

Examples of how to use sleeve terminals (pin holders)

The sleeve terminal (pin holder) 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 (pin holders) are used for IGBT modules and substrates for power semiconductors such as SiC modules.

Sample use of IGBT and SiC-module

IGBT and SiC-modules are used in a variety of applications, including inverters for HEV/EV and trains, uninterruptible power supplies (UPSs), and air conditioners (household appliances).

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 pins into sleeve terminals (pin holders). When using the automatic insertion machine, the press-fit pins will be delivered as end-to-end pins.
