Abstract
An entry port system for connecting a co-axial cable to a printed circuit board within a housing has a terminating connector on the cable at the exterior of the housing and a connector member within the housing and connected to the cable shield. The printed circuit board is secured to the connector member so as to be supported and grounded thereby. A terminal, mounted on the printed circuit board, holds a central conductor of the terminating conductor, which extends through a passage in the connector member, at a spacing from the connector member, so that an air gap surrounds the central conductor in the passage. The size of the air gap is selected so that the entry port system acts as a co-axial transmission system having an impedance substantially equal to that of the cable.
Claims9
An entry port system for a co-axial cable having a first central conductor and an outer shield, said entry port system comprising:
- a housing;
- said housing having a wall and an entry port formed in said wall;
- a terminating connector provided at the exterior of said housing at one end of said co-axial cable;
- said terminating connector having a second central conductor connected to said first central conductor;
- a further connector;
- said further connector comprising a connector member located within said housing and a first fastener securing said connector member to said wall at said entry port;
- a printed circuit board located within said housing;
- a second fastener securing said printed circuit board to said connector member;
- said further connector and said terminating connector forming an electrical connection between said printed circuit board and said outer shield of said cable so that said printed circuit board is grounded through said connector member;
- said connector member being formed with a passage through which said second central conductor projects into the interior of said housing;
- and
- a terminal provided within said housing and electrically connecting said second central conductor to said printed circuit board.
