Abstract

Systems that establish connection between radiofrequency (RF) coaxial cables are disclosed. The systems establish a connection between either two RF coaxial cables or a connection between an RF coaxial cable and a board which has an RF coaxial connection. The systems are described with respect to a single connection. The systems can be extended to bundle in a form of Sub-D connectors to establish multiple connectors. The connections use a female and a male connector to establish a connection under either normal polarity or reverse polarity. Such system of RF coaxial cable connections is used for magnetic resonance imaging (MRI) scanners in a receive chain, where in, a signal is transmitted from a coil to a receiver box.

COAXIAL CONNECTOR SYSTEM

BACKGROUND

The present invention relates generally to a connector system and more particularly to a radiofrequency (RF) coaxial connector system.

Generally, a connector system is used for connecting radiofrequency (RF) coaxial cables. The number of transmission cables within a cable is required to be increased to handle an increased amount of data. For systems having 64 channels, an 8W8 connector system is used, which requires stacking of eight separate connector systems. However, stacking of large number of connector systems requires a significant amount of space.

A conventional technique includes a 16W16 connector system for connecting RF coaxial cables. The system includes several components, such as, a plug, a receptacle, and a transition body, wherein the plug and receptacle are configured to operate under a ground-first mating condition. The plug includes a D-sub housing having two rows of eight RF coaxial contacts and a plurality of protrusions extending therefrom. The receptacle includes a D-sub housing having two rows of eight openings and a plurality of indentations that are sized and positioned so as to mate with the protrusions extending from the plug. The receptacle includes a rear unibody joined with the D-sub housing and a transition body positioned between and joining the D-sub housing and the rear unibody.  The conventional technique requires stacking of four separate connector systems, thereby decreasing amount of space required. However, the ground-first mating condition is not necessary for medical imaging machines, such as, medical resonance imaging (MRI) machines. Therefore, the conventional system cannot be used for MRI machines.  

Therefore, it would be desirable to have a RF coaxial connector system design that occupy limited space and can be used in several applications.
