Solder Ring Placement for Multiple Pin Electrical Connector

An array plate is used as a placement device for locating individual solder rings on each pin of a multiple pin electrical connector prior to soldering. The device works as follows.

The device is shown in Fig. 1. It consists of a feed mechanism 1, that is mounted on an array plate 2. The array plate 2 has four steps

or tiers (the number of rows of pins on which the solder rings are to be placed), seen in the end view of Fig. 2. Each tier has a series of locating nests 3 distributed evenly along the four-tier array plate 2, where solder rings 4 are held prior to placement onto the connector pins (not shown). The array plate is movable along an axis indicated by the arrows (Fig. 1), while the feed mechanism has a fixed mounting.

In Fig. 3, a cross-section view of the feed mechanism 1, solder rings 4 are fed from vibratory, centrifugal, or other suitable bowl feeder (not shown) into a chute 5 where solder rings are delivered to feed mechanism where rings are stacked. As shown in Fig. 2, an end view of the feed mechanism, four separate chambers of the feed mechanism contain four stacks of solder rings. The four feed mechanism chambers correspond to the four tiers on the array plate. The rings are fed by gravity into the multiple slots 6 (Fig. 3) of the array plate by the reciprocating motion of the array plate as it moves under the feed mechanism. Slots 6 (Fig. 5) are provided to correspond with each row of pins on the electrical connector being ringed.

The individual slots or nests are dimensioned such that only one ring may enter each slot. The spacing of the slots is arranged to match the array of pins on the connector. Each nest holds the solder ring in the pro...
