Center conductor terminal having increased contact resistance
View Patent ↗A terminal assembly is provided for terminating a center conductor of a coaxial cable. The terminal assembly includes a terminal body having a pin at one end and a cavity at the other end for accommodating a center conductor therein. A contact member is supported within the cavity. The contact member includes plural inwardly directed cantilevered beams extending from a contact base for deflectable engagement with the inserted center conductor. The terminal body includes an inwardly directed shoulder for engagement with the beams at a location between the base and the distal ends of the beams. The location defines a deflection fulcrum at a location distal from the base so as to provide increased contact engagement force between the distal ends of the beams and the center conductor.
1. A terminal assembly for terminating a center conductor of a coaxial cable comprising:
a terminal body having a pin at one end and a center cavity at the other end for accommodating said center conductor therein; and
a contact member supported within said central cavity, said contact member having plural inwardly directed cantilevered beams extending inwardly away from a contact base for deflectable engagement with said inserted central conductor;
said terminal body having an inwardly directed shoulder for engagement with said beams at a location between said base and distal ends thereof;
said location defining a deflection fulcrum for said beams at a location distal of said base so as to provide an increased contact engagement force between said distal ends of said beams and said center conductor.
2. A terminal assembly of claim 1 wherein contact is press-fit into said cavity.
3. A terminal assembly of claim 1 wherein said base is an annular member and said beams extend from said base at locations spaced circumferentially thereabout.
4. A terminal assembly of claim 1 wherein said contact beams provide said contact engagement force with said center conductor having a range of diameters.
5. A terminal assembly of claim 1 wherein said terminal body, said contact member and said center conductor are formed of conductive material.
6. A connector of claim 1 wherein said pin is a right angle pin.
7. A coaxial connector for terminating a coaxial cable having a center connector extending from one end thereof, said connector comprising:
a connector body having a cable receiving end;
a terminal body supported within connector body, said terminal body having a pin at one end and a cavity at the other end for accommodating said inserted center connector,
a contact member supported within said cavity, said contact member having at least one inwardly directed cantilevered beam for deflectable engagement with said inserted center connector; said beam extending inwardly from a base portion;
said terminal body having an inwardly directed shoulder for engagement with said beam at a location spaced apart from said base portion, said location defining a deflection fulcrum so as to provide increased engagement force between said beam and said center connector; and
a locking sleeve insertable into said cable receiving end of said connector body and movable to lock said cable in said connector body.
8. A connector of claim 7 wherein said contact member includes a plurality of said cantilevered beams.
9. A connector of claim 8 wherein said plural beams extend from a contact base to said distal ends thereof.
10. A connector of claim 9 wherein said location is defined between said contact base and said contact distal ends of said beams.
11. A connector of claim 10 wherein each said beam includes a contact portion adjacent said distal end for engagement with said center conductor.
12. A connector of claim 11 wherein said contact portion is curved.
