Electrical connector hold down anchor apparatus

Claim 2

An electrical connector hold down apparatus for engaging a side wall defining a hole in a printed circuit board to secure the electrical connector to the printed circuit board, the apparatus comprising: a base; and at least two spring beams extending away from the base, each spring beam being configured to apply a radially outwardly directed force against the side wall defining the hole in the printed circuit board, each spring beam including a body portion and an anchor tip portion, the anchor tip portions being bent with respect to the central axis of the hole so as to curve radially outwardly relative to the base to define a pair of ramp surfaces for moving the spring beams radially inwardly upon insertion of the spring beams into the hole in the printed circuit board, each ramp surface being formed to include a barb configured to penetrate the side wall defining the hole in the printed circuit board to increase a retention force of the hold down apparatus in the hole.

Claim 3

The apparatus of claim 1, wherein the base is formed to include an aperture therein for receiving a support peg formed on the electrical connector therethrough to couple the base to the electrical connector.

Claim 4

The apparatus of claim 2, wherein the support peg is heat staked after the aperture in the base is inserted over the support peg to couple the base to the electrical connector.

Claim 5

The apparatus of claim 1, wherein the barbs are formed on a trailing end of each ramp surface.

Claim 6

The apparatus of claim 1, wherein the apparatus includes three said spring beams coupled to the base to provide a three point contact with the side wall defining a hole in the printed circuit board to center the hold down apparatus relative to the hole.

Claim 7

The apparatus of claim 5, wherein the three spring beams are angularly spaced apart on the base by about 120°.

Claim 8

An electrical connector hold down apparatus for engaging a side wall defining a hole in a printed circuit board to secure the electrical connector to the printed circuit board, the apparatus comprising: a base; and three cantilevered beams extending away from the base, each cantilevered beam including a body portion and an anchor tip portion, each anchor tip portion being bent with respect to the central axis of the hole so as to curve radially outwardly relative to the base to define a pair of ramp surfaces for engaging the side wall defining the hole in the printed circuit board to move the cantilevered beams radially inwardly as the connector upon insertion of the cantilevered beams into the hole in the printed circuit board so that the cantilevered beams apply a radially outwardly directed force against the side wall to hold the apparatus within the hole, the ramped surfaces being formed to include a barb configured to penetrate the side wall defining the hole in the printed circuit board due to the radially outwardly directed force applied by the cantilevered beams to increase a retention force of the hold down apparatus in the hole.

Claim 9

An electrical connector hold down apparatus for engaging a side wall defining a hole in a printed circuit board to secure the electrical connector to the printed circuit board, the apparatus comprising: a base; and three cantilevered beams extending away from the base, each cantilevered beam including a body portion and an anchor tip portion, each anchor tip portion being bent with respect to the central axis of the hole so as to curve radially outwardly relative to the base to define a pair of ramp surfaces for engaging the side wall defining the hole in the printed circuit board to move the cantilevered beams radially inwardly as the connector upon insertion of the cantilevered beams into the hole in the printed circuit board so that the cantilevered beams apply a radially outwardly directed force against the side wall to hold the apparatus within the hole, the ramped surfaces being formed to include a barb configured to penetrate the side wall defining the hole in the printed circuit board due to the radially outwardly directed force applied by the cantilevered beams to increase a retention force of the hold down apparatus in the hole.

Claim 10

The apparatus of claim 7, wherein the base is formed to include an aperture therein for receiving a support peg formed on the electrical connector therethrough to couple the base to the electrical connector.

Claim 11

The apparatus of claim 8, wherein the support peg is heat staked after the aperture in the base is inserted over the support peg to couple the base to the electrical connector.

Claim 12

The apparatus of claim 7, wherein the three cantilevered beams are angularly spaced apart on the base by about 120°.

Claim 13

An electrical connector hold down apparatus for engaging a side wall defining a hole in a printed circuit board to secure the electrical connector to the printed circuit board, the apparatus consisting essentially of: a base; and a plurality of spring beams extending away from the base, each spring beam including a body portion and an anchor tip portion, each anchor tip portion being bent with respect to the central axis of the hole so as to curve radially outwardly of the base to define a pair of ramp surfaces configured to engage the side wall defining the hole in the printed circuit board and to move the spring beams radially inwardly so that the spring beams apply a radially outwardly directed force against the side wall to hold the apparatus within the hole.

Claim 14

An electrical connector hold down apparatus for engaging a side wall defining a hole in a printed circuit board to secure the electrical connector to the printed circuit board, the apparatus consisting essentially of: a base; and a plurality of spring beams extending away from the base, each spring beam including a body portion and an anchor tip portion, each anchor tip portion being bent with respect to the central axis of the hole so as to curve radially outwardly of the base to define a pair of ramp surfaces configured to engage the side wall defining the hole in the printed circuit board and to move the spring beams radially inwardly so that the spring beams apply a radially outwardly directed force against the side wall to hold the apparatus within the hole.

Claim 15

The apparatus of claim 11, wherein the anchor tip portions also include a barb formed on a trailing end of the ramp surface, the barbs being configured to penetrate the side wall defining the hole in the printed circuit board to increase a retention force of the hold down apparatus in the hole.

Claim 16

The apparatus of claim 11, wherein the apparatus includes three said spring beams coupled to the base to provide a three point contact with the side wall defining a hole in the printed circuit board to center the hold down apparatus relative to the hole.

Claim 17

The apparatus of claim 13, wherein the three spring beams are angularly spaced apart on the base by about 120°.
