Abstract

Abstract The present invention relates to a method and apparatus for simultaneously assembling a plurality of elongated contacts within corresponding apertures provided in a printed circuit board. According to the assembly techniques of the present invention, an entire row of elongated contacts are initially manually inserted into corresponding rows of P.C. board apertures with the aid of a hand tool. In the present invention, the printed circuit board is mounted on a carriage of an insertion machine. The initially inserted row of contacts partially protrudes through the P.C. board and is received in the jaws of a vise. In the operation of the insertion machine, the vise jaws close and grip the row of protruding contacts. Sequentially, a limited and precisely adjusted relative motion is effected between the P.C. board carriage and the vise. Such operation causes a corresponding limited and precisely controlled relative displacement between the inserted row of contacts and the P.C. board, thus forcibly positioning and seating the enlarged, interference fit portions of the contacts within corresponding apertures of the P.C. board. In this manner, all contacts of the row are precisely positioned simultaneously in desired registration within the printed circuit board. Sequentially, the vise jaws are opened, allowing an operator of the machine to remove the contacts therefrom and reposition the P.C. board on the carriage for insertion of another row of contacts. With the board thus repositioned, the machine may be reset for a repeated cycle of operation. In a modification of the machine, a mechanism is provided which is actuated after opening of the jaws, thereby automatically removing the row of contacts from the jaws. The purpose of this operation is to provide a substantial clearance between the P.C. board and the jaws, allowing the operator to reposition the P.C. board on the carriage without interfering with the vise jaws. With the P.C. board repositioned (desirably for insertion of another row of contacts) the operator may then reset the machine for a repeated cycle of operation.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 113 words
A method of inserting contacts in a P.C. board provided with apertures, comprising the steps of: providing a plurality of contacts in serial fashion along a carrier strip, gripping and aligning each of said contacts in desired serial fashion with a comb-like tool, introducing simultaneously all of said contacts in corresponding apertures of said P.C. board using said tool, gripping said contacts as they protrude from the apertures beneath the P.C. board, seating said contacts within the apertures of said P.C. board as they remain gripped beneath the P.C. board, securing said contacts fixedly in place in said corresponding apertures of said P.C. board, and removing said carrier strip from said secured contacts.
Claim 2
Independent Claim 113 words
A method of inserting contacts in a P.C. board provided with apertures, comprising the steps of: providing a plurality of contacts in serial fashion along a carrier strip, gripping and aligning each of said contacts in desired serial fashion with a comb-like tool, introducing simultaneously all of said contacts in corresponding apertures of said P.C. board using said tool, gripping said contacts as they protrude from the apertures beneath the P.C. board, seating said contacts within the apertures of said P.C. board as they remain gripped beneath the P.C. board, securing said contacts fixedly in place in said corresponding apertures of said P.C. board, and removing said carrier strip from said secured contacts.
Claim 3
Dependent Claim 82 words
The method as recited in claim 1, further including the steps of: locating said P.C. board in alignment with a vise, receiving said contacts in said vise upon introduction of said contacts in said apertures of said P.C. board, gripping said contacts with said vise, causing relative displacement between said contacts and said P.C. board to seat said contacts in said P.C. board prior to the step of securing said contacts fixedly in place in said corresponding apertures of said P.C. board.
Claim 4
Dependent Claim 62 words
The method as recited in claim 2, and further including the step of: removing said P.C. board and said contacts from said vise subsequent to the step of causing relative displacement between said contacts and said P.C. board, and wherein the step of securing said contacts fixedly in said corresponding apertures further includes the step of: soldering said contacts in said apertures.
Claim 5
Dependent Claim 107 words
The method as recited in claim 3, wherein the step of soldering said contacts in said apertures further includes the steps of: providing a band of solder encircling and adhered to each of said contacts while said contacts are provided in serial fashion along the carrier strip, and further including the steps of: positioning said bands of solder adhered to said contacts within corresponding apertures, and reflowing the bands of solder to form solder joints substantially within the apertures to thereby secure the contacts fixedly in place within the apertures of said P.C. board prior to the step of removing said carrier strip from said secured contacts.
Claim 6
Independent Claim 156 words
A method of inserting contacts in a P.C. board provided with apertures, comprising the steps of: providing a plurality of contacts in serial fashion along a carrier strip, gripping and aligning each of said contacts in a desired serial fashion within a comb-type tool, locating said P.C. board in alignment with a vise, introducing simultaneously all of said contacts in corresponding apertures of said P.C. board using said tool, receiving said contacts in said vise upon introduction of said contacts in said apertures of said P.C. board, gripping said contacts with said vise, displacing said P.C. board and maintaining said vise in a fixed position while said contacts remain gripped by said vise to cause relative displacement between said contacts and said P.C. board and to seat said contacts in said P.C. board, securing said contacts fixedly in place in said corresponding apertures of said P.C. board, and removing said carrier strip from said secured contacts.
Claim 7
Independent Claim 156 words
A method of inserting contacts in a P.C. board provided with apertures, comprising the steps of: providing a plurality of contacts in serial fashion along a carrier strip, gripping and aligning each of said contacts in a desired serial fashion within a comb-type tool, locating said P.C. board in alignment with a vise, introducing simultaneously all of said contacts in corresponding apertures of said P.C. board using said tool, receiving said contacts in said vise upon introduction of said contacts in said apertures of said P.C. board, gripping said contacts with said vise, displacing said P.C. board and maintaining said vise in a fixed position while said contacts remain gripped by said vise to cause relative displacement between said contacts and said P.C. board and to seat said contacts in said P.C. board, securing said contacts fixedly in place in said corresponding apertures of said P.C. board, and removing said carrier strip from said secured contacts.
