The industry leaders in this blade type of connector are Cinch and Molex (Beau). They offer a product line that is compatible and very similar in the product specifications. Both brands have long history and even used similar part numbers for this style of connector.

Cinch for many years used the name Cinch Jones in order to reinforce its connection with the Howard P Jones Company that was an originator of this type of connector. They referred to this type of product as “Jones” plugs and sockets in their promotional literature and catalogs. In time the Cinch name became more popular and is a premier manufacturer of this type of connector.

Molex bought the Vernitron Corporation which had acquired the “Beau” products division.
