Self-staking wire grip terminal

Claim 2

A circuit board eyelet adapted to be staked in a circuit board hole comprising a hollow generally cylindrical body, flange means at one end of the body having a central longitudinal axis, and a plurality of spaced staking fingers extending away from the other end of the body with the free ends of the fingers grouped together in converging relation adjacent the axis of the eyelet, each finger including a sharp outer bend located between the body and the finger ends defining an apex facing generally inwardly toward said axis and a sharp inner bend defining an apex facing generally outwardly away from said axis located between the body and the outer bend, whereby during staking the portions of the fingers between the body and the outer bends are pivoted away from said axis and into contact with the adjacent edge of the circuit board hole, the ends of the fingers forming means for receiving and holding a lead inserted through the eyelet body.

Claim 3

A circuit board eyelet as in claim 1 wherein each finger includes a first flat portion extending from the body to said inner bend, a second flat portion extending from the inner bend to the outer bend and a third flat portion extending form the outer bend to the end of the finger.

Claim 4

A circuit board eyelet as in claim 2 wherein in each finger the outer bend is located further from a line extending from the tip of the finger to the junction between the finger and the body than the inner bend.

Claim 5

A circuit board eyelet as in claim 3 wherein the width of each finger at the inner bend is less than the width of the finger at the outer bend.

Claim 6

A circuit board eyelet comprising a generally cylindrical body having a central longitudinal axis, an outwArdly extending flange at one end of the body, and a plurality of collapsable fingers extending from the other end of the body, each finger including a sharp outer bend located approximately midway along the length thereof defining an apex facing generally inwardly toward said axis and a sharp inner bend located approximately midway along the portion thereof between said body and said outer bend defining an apex facing generally outwardly, away from said axis, said outer bend being located further from a line extending from the tip of the finger to the junction between the finger and the body than said inner bend whereby upon axial collapse of the eyelet positioned in the circuit board hole said legs first collapse about said outer bend to move said leg portions outwardly against the circuit board hole to confine the eyelet in the hole.

Claim 7

A circuit board eyelet comprising a generally cylindrical body having a central longitudinal axis, an outwArdly extending flange at one end of the body, and a plurality of collapsable fingers extending from the other end of the body, each finger including a sharp outer bend located approximately midway along the length thereof defining an apex facing generally inwardly toward said axis and a sharp inner bend located approximately midway along the portion thereof between said body and said outer bend defining an apex facing generally outwardly, away from said axis, said outer bend being located further from a line extending from the tip of the finger to the junction between the finger and the body than said inner bend whereby upon axial collapse of the eyelet positioned in the circuit board hole said legs first collapse about said outer bend to move said leg portions outwardly against the circuit board hole to confine the eyelet in the hole.

Claim 8

A circuit board eyelet as in claim 5 wherein said eyelet includes a set of wire grip fingers extending from outer edges of said flange into the opening at one end of the body, the ends of such fingers being spaced closely together to receive and hold a lead inserted into the body.
