The highly-rigid 5mm stainless screw is used for the 4mm cable penetration part. This infills inside space between the body and the screw. The blue screws, made of stainless with quench hardening treatment, are highly-rigid and emphasize the beauty of SRBN. After careful polishing by hand and mirror finishing, the body is completed with silver (inner) and rhodium (outer) plating.
Material / Structure
Smooth and Tight. This is the theme that SRBN aimed to only by characteristic of materials. To hold tightly by using minimum components, SRBN is made by deoxidized phosphor bronze which is used in many contacts due to its excellent springiness and electric property.
When SRBN are planned, we paid most careful attention to the design of its contact tip. It is slit up in a cross shape and divided in quarters to ensure the maximum contact area and is designed to be fit tightly into terminals when it is inserted.
The size was determined based on WBT’s speaker terminals, but it can be fit in any terminals. After more than ten times of repeated cut and try, SRBN was exquisitely-designed to be inserted smoothly and not to be come off easily.
The maximum install cable O.D is 4mm (5.5sq).
By employing 5mm dual screw connection system, it infills inside space and holds conductor perfectly. The blue screws, made of stainless with quenching treatment, are highly-rigid and emphasize the beauty of SRBN.
Processing
The design concept of SRBN is inspired by “Breguet”, the luxurious Swiss watch. The slip resistance engraved on the body is reminiscent of Guilloche pattern on a surface. Furthermore, the screw is blue steel processed by quench hardening using same technique as hands of a watch for the purpose of improvement of mechanical strength and oxidation resistant.
The body is trimmed down from 8mm phosphor bronze bar by precision CNC machining. It is finished by mechanical barreling and hand polishing piece by piece. The plating of the mirror finished body is a combination of silver (1.5μ, inner) + rhodium (0.3μ, outer).
