Abstract

A banana plug center pin with a raised break point is disclosed. The banana plug center pin comprises a top portion and a bottom portion. The top portion has a first diameter, and the bottom portion has a second diameter. The banana plug center pin with a raised break point further includes a locking ring peripherally surrounding the center pin at the interface of the top portion and the bottom portion. Additionally, the banana plug center pin has a fillet feature coupled to the bottom portion and the locking ring. In one embodiment, the interface of the top portion and the bottom portion is located such that when the center pin is inserted into a banana jack, the interface is disposed above a top edge of the banana jack.

19. A banana plug with a raised break point, said banana plug comprising:

a center pin with a raised break point, said center pin comprising;

a top portion, said top portion having a first diameter;

a bottom portion, said bottom portion having a second diameter, said second diameter smaller than said first diameter;

a locking ring peripherally surrounding said center pin at an interface of said top portion and said bottom portion, said locking ring having a flat formed on a surface thereof and wherein said interface of said top portion and said bottom portion is located such that said interface is disposed above a top edge of a banana jack when said banana plug is inserted into said banana jack; and

a fillet feature coupled to said bottom portion and said locking ring, said locking ring, said flat, and said fillet feature configured to prevent movement of said center pin with respect to overlying material;

a spring contact coupled to said center pin, said spring contact peripherally surrounding at least some of said bottom portion of said center pin;

a cable conductor having a first end electrically coupled to said center pin, and a second end extending into a cable jacket;

a crimped strain relief having openings formed therein, said crimped strain relief compressed about said cable jacket such that said cable jacket bulges at least partially through said openings;

an outer housing at least partially encapsulating said cable jacket, said cable conductor, and at least some of said top portion of said center pin; and

an inner component disposed at least partially between said outer housing and said center pin, said inner component having protrusions extending there from, said protrusions configured to prevent movement of said inner component with respect to said outer housing, said inner component comprised of a material having a greater hardness than material comprising said outer housing.

20. The banana plug with a raised break point of claim 19 further comprising:

a second locking ring peripherally surrounding said center pin, said second locking ring disposed above said interface of said top portion and said bottom portion.

19-1. The banana plug with a raised break point of claim 19 further comprising:

a pull tab coupled to said outer housing.
