Rugged environment electrical connector specialist Rampart Products has specified a Victrex polymer blend for a new HPHT (high pressure-high temperature) rotatable electrical connector for reliable transmission of power and data used in oilfield drilling equipment. During material selection and the development of the moulding process, Rampart worked closely together with Victrex.

Rampart´s new rotatable connector made with Victrex material was designed for temperatures of 400°F (200°C) and pressures at 20,000+ psi (1380 bar) providing a reliable electrical connection while protecting expensive sensors and electronics.

Traditionally, a machined and assembled design containing wire and solder joints are used in the rotatable connector market. This approach can result in a structurally weak system with poor shock and vibration resistance. The custom Victrex PEEK blend-based Rampart Products´ male rotatable connector is a completely moulded unitized solution that is structurally much stronger, has no internal wire or solder joints to fail under shock or vibration and fewer components. An added benefit is the unitized all-moulded design creates a high pressure, integrated bulkhead. The female rotatable connector has a semi-unitized body, also eliminating wire while allowing for Rampart to mould a high-pressure seal where the connector shoulders, while incorporating a machined/assembled solution for ease of assembly.
