A recess is formed in each passageway. Each contact has a deformable portion having a tip provided at an end thereof. The deformable portion is capable being in an undeformed position and in a deformed position. When a lateral force is placed on the deformable portion of each contact, at least a portion of the tip is maintained within the recess. The recess is sized and configured to limit lateral deflection of the tip upon deformation of the deformable portion in a lateral direction.
FIELD OF THE INVENTION The present invention relates to a land grid array connector having a conductive contact and a housing with a recess therein for protecting a tip of the conductive contact.
BACKGROUND OF THE INVENTION Land grid array connectors are commonly used with integrated circuits. Conventional land grid array connectors include an insulative housing which defines a plurality of passageways therethrough, and a plurality of conductive contacts received in the passageways. The land grid array connector is connected to an integrated circuit which has a plurality of flat contact pads formed on a bottom surface thereof to which the contacts are electrically mated.
OBJECTS AND SUMMARY OF THE INVENTION The primary object of the present invention is to provide a land grid array connector which protects a conductive contact mounted therein from plastically deforming upon the application of a lateral force to the conductive contact.
The structure of one of the contacts 26 is described herein with the understanding that the other contacts 26 are identically formed. The contact 26 is formed from a conductive material, such as metal, and can be formed by stamping and forming. As such, the contact 26 can be economically manufactured. The contact 26 is formed in generally an �S� shape as shown in FIG. 4. The contact 26 includes a first or upper portion 28, a second or middle portion 30 and a third or lower portion 32. The upper portion 28 can be deformed relative to the middle and lower portions 30, 32 such that the upper portion 28 can move vertically or laterally relative to the middle and lower portions 30, 32. The �S� shape of the contact 26 minimizes translation of the contact 26 when a vertical or lateral force is placed thereon.
The upper portion 28 of the contact is formed by a first part 52 which extends from the first section 50, a second part 54 which extends from the first part 52, a third part 56 which extends from the second part 54, a fourth part 58 which extends from the third part 56, a fifth part 60 which extends from the fourth part 58, and a sixth part 62 which extends from the fifth part 60. The first part 52 curves upwardly from the first section 50 and extends in the same direction as the lower portion 32 of the contact 26. The second part 54 extends upwardly from the first part 52 and is angled relative to the horizontal as shown in FIG. 4. In addition, the second part 54 angles relative to the vertical toward the first side 42 of the middle portion as is most clearly shown in FIG. 5. The third part 56 is generally U-shaped. The fourth part 58 extends upwardly from the third part 56 and is angled relative to the horizontal as shown in FIG. 4. In addition, the fourth part 58 angles relative to the vertical toward the second side 44 of the middle portion 30 as is most clearly shown in FIG. 5. The fifth part 60 is generally L-shaped. The sixth part 62 extends downwardly from the fifth part 60 toward the top edge 40 of the middle portion 30. When the contact 26 is not deformed as shown in FIGS. 2�5 and 8, the sixth part 62 is generally parallel to the middle portion 30, but in a plane offset from the plane containing the middle, or fixed portion, of the contact 26. As is best illustrated in FIG. 2, the width of the first, second and third parts 52, 54, 56 is consistent along their lengths; the width of the fourth part 58 along its length tapers downwardly from the third part 56 to the fifth part 60; and the width of the fifth part 60 is consistent along its length. The sixth part 62 has a width that is wider than the fifth part 60 such that an enlarged tip is formed relative to the fifth part 60. The fifth part 60 is the portion of the contact 26 which will be in contact with the mating component, such as a contact pad on a printed circuit board 63. The upper portion 28 of the contact 26 can be deformed relative to the middle and lower portions 30, 32 by applying a downward force to the fifth part 60 of the upper portion 28.
