Abstract
Abstract A machine is disclosed for mass insertion of multiple terminals into preformed passageways in housings, printed circuit boards or the like. The terminals each have one end detachably secured to a flexible carrier strip and are transported to the insertion station thereby. The machine grips large groups of the terminal in the insertion station, removes them from the carrier strip, and inserts the terminals into the preformed passageways in a housing, printed circuit board, or the like. The terminals are carried and inserted in two parallel spaced rows, with the alignment therebetween being insured by a shuttle which is placed between the rows of terminals at the insertion station. The group of terminals to be inserted is grasped by jaw members and held against the shuttle during the insertion movement. The jaws then release the terminals and return the shuttle to its original position. The subject machine can be used in a single head or in multiple head embodiments to selectively insert groups of terminals to achieve the desired total number of terminals inserted in any one fixture.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
211 words
An application machine for effecting mass insertion of electrical terminals into preformed apertures in housings, printed circuit boards, and the like in a closely spaced, high density array, the terminals each having one end adapted to form an interference fit in a respective preformed aperture and the other end detachably secured, to depend in two parallel spaced rows from a flexible carrier tape, said machine comprising: a substantially closed housing defining a cavity therein; a first assembly slidably mounted within said cavity; a second assembly slidably mounted concentrically within said first assembly; a shuttle assembly having a fixed mandrel with a detachable shuttle member positioned within said cavity to lie between said rows of terminals; a gripping assembly mounted in said second assembly for gripping each said row of terminals against an adjacent side of said shuttle member and releasing said terminals after insertion; drive means for imparting reciprocal motion to said first and second assemblies and movement to said gripping assembly; whereby said tape carried terminals are fed between said gripping assembly and an adjacent side of said shuttle assembly and grasped therebetween, stripped from said tape, transported to and inserted into said preformed apertures, and released by said gripping assembly which returns said shuttle member to its original position.

Claim 3
Dependent Claim
23 words
An application machine according to claim 1 further comprising: wear plates mounted in said housing, said first assembly sliding against said wear plates.
Claim 4
Dependent Claim
28 words
An application machine according to claim 1 further comprising: drag means in said housing for applying drag force to said first assembly whereby the motion thereof is controlled.
Claim 5
Dependent Claim
39 words
An application machine according to claim 1 wherein said first assembly comprises: a pair of parallel spaced plates; said housing having walls defining channels in which said plates slide; and means directly driving said plates from said drive means.
Claim 6
Dependent Claim
85 words
An application machine according to claim 1 wherein said second assembly comprises: an open ended box of plate members received within said first assembly and opening in the direction of movement; means for pivotally mounting said gripping assembly within said box; means connecting said second assembly to said drive means; and elongated slots in opposing ones of said plate members whereby driving movement from said drive means is imparted to said second assembly after a delay from the commencement of movement of said drive means.
Claim 7
Dependent Claim
48 words
An application machine according to claim 1 wherein said shuttle assembly comprises: a mandrel fixed with respect to said housing in a position intermediate the rows of terminals; and a shuttle member detachably held to said mandrel to be removed therefrom and returned thereto by said gripping assembly.
Claim 8
Dependent Claim
56 words
An application machine according to claim 6 wherein said mandrel has an elongated arm with a plurality of apertures therein; and said shuttle member has at least one rigid alignment pin and at least one spring pin projecting from a surface thereof and positioned to engage in respective ones of said apertures in said mandral arm.
Claim 9
Dependent Claim
