A carrier (1) comprises a guiding tape (10) from which a plurality of linking strips (11) extend and engage with a plurality of contacts (12) each of which comprises a mating portion (121) having a first half (1211) and a second half (1212) connected to each other via an engagement plate (1213). A plurality of compliant pins (122) extends from the first half (1211) and each compliant pin (122) terminates as a free end (123). A plurality of linking strips (11) engages with each first half (1211). A guiding tape (10) engages with the linking strips (11) so that each linking strip (11) is connected between the first half (1211) and the guiding tape (10). A coining step to round the edge of compliant portions (1223) is to be carried out. The attachment of the guiding tape (10) to the linking strips (11) rather than to the free ends (123) of the compliant pins (122) facilitates such coining step.
A carrier comprising a guiding tape from which a plurality of linking strips extend and engage with a plurality of contacts each of which comprises a mating portion having a first half and a second half connected to each other via an engagement plate, a plurality of compliant pins extending from the first half and each compliant pin comprising a leg portion extending from the first half of the contact, an engagement portion extending laterally from the leg portion for engaging with a corresponding linking strip, and a compliant portion which defines a hole for providing a tolerance for deformation when the compliant portion is inserted into and retained in a hole of a circuit board, the linking strips engaging with each first half, and the guiding tape engaging with the linking strips so that each linking strip is connected between the first half and the guiding tape.
A method for making contacts comprising steps of:
A carrier after stamping comprising a guiding tape and a plurality of contacts side by side arranged with one another, each contact comprising free ended legs and middle engagement portions formed on the legs, said contacts being substantially laterally spaced from the guiding tape, and being connected to said guiding tape through a plurality of linking strips, wherein portions of each linking strip are connected to the middle engagement portions of two adjacent ones of said legs instead of to free ends of the legs.
A carrier comprising a guiding tape from which a plurality of linking strips extend and engage with a plurality of contacts each of which comprises a mating portion having a first half and a second half connected to each other via an engagement plate, a plurality of compliant pins extending from the first half, the linking strip having a shoulder and engaging with each first half so that each linking strip is connected between the first half and the guiding tape, each compliant pin comprising a leg portion extending from the first half of the contact and terminating as a free end, each linking strip located between two compliant pins, an engagement portion extending laterally from the leg portion of the compliant pin and engaging with the adjacent shoulder of the linking strip, a compliant portion which defines a hole for providing a tolerance for deformation when the compliant portion is inserted into and retained in a hole of a circuit board.
