M85049/128 EMI/RFI Shield Termination Bands
History of Termination Bands
About 20 years ago a company, Band-It, developed a stainless steel band/strap to terminate braid/shield onto an electrical connector. The
standard method of terminating braid/shield at that time was by use of cone(s) on the inside of the connector backshell.
A proper termination requires several assembly steps by a skilled assembler. You can't just take
someone "off-the-street" and expect them to make a proper termination. Additionally, you could not see/view the termination to determine if it was done correctly. Electrical and other tests are required.
With use of a termination band, the assembler places the braid/shield over the rear of the backshell, wraps the band around the shield 2-3 times and lightens the band with a tool.
This has proved to be a much quicker assembly method and you can see if the braid/shield is properly attached.
Glenair and Band-It secured a patent on this termination band but it expired on November 10, 2008.
Both Electro-Adapter and Sunbank designed bands to compete with Glenair but their locking mechanism was different and wasn't patentable.
Types of Connector Termination Bands
There are two categories of termination bands. One is called Quarter Inch (Width is .250 ± .010 and
length is 14.25 inches.) The other is a Mini-Band (Width is .120 ± .010) and (length is 8.125 inches.).
Coiled and Flat Termination Bands
The Termination Bands are used to attach a braid or a shield to a backshell. They come in two shapes:
Coiled and Flat. Electro-Adapter, Glenair and Sunbank have such a device. Each company has their own tool. Some bands will only work when you use the respective tools. As an example: A Glenair band will
work in a Sunbank tool, but a Sunbank band will not work in a Glenair tool.
Spacecraft is now in a position to supply equal parts to the termination bands from Electro-Adapter,
Glenair, Band It and Sunbank. To find out more and to buy termination bands and mini bands, please Request a Quote.
