Male (left) and female Belling-Lee connectors
|Type||RF coaxial connector|
|Designer||Belling & Lee Ltd in Enfield, United Kingdom|
|Designed||Around 1922 (Belling-Lee)|
The Belling-Lee connector (also type 9,52, but largely only in the context of its specification, IEC 61169, Part 2: Radio-frequency coaxial connector of type 9,52) is commonly used in Europe and Australia to connect coaxial cables with each other and with terrestrial VHF/UHF roof antennas, antenna signal amplifiers, CATV distribution equipment, TV sets, and FM and DAB radio receivers. In these countries, it is known colloquially as a PAL antenna connector, IEC antenna connector, or simply as a TV aerial plug. It is one of the oldest coaxial connectors still commonly used in consumer devices.
It was invented at Belling & Lee Ltd in Enfield, United Kingdom around 1922 at the time of the first BBC broadcasts. Belling Lee Limited still exists as a wholly owned subsidiary of Dialight, since 1992.
In type 9,52, the 9,52, in French SI style, refers to the 9.525 mm (3⁄8, or 0.375 in) male external and female internal connector body diameter.
In their most common form the connectors just slide together. There is, however, also a screw-coupled variant which is specified to have a M14×1 thread.
There is also a miniature Belling-Lee connector which was used for internal connections inside some equipment (including BBC RC5/3 Band II receiver and the STC AF101 Radio Telephone). The miniature version is only about 4.4 millimetres (0.17 in) in diameter.
