Abstract
A tool for i) aligning a bore pattern on a wafer with a corresponding pattern in a connector, and ii) maintaining the alignment of the wafer bore pattern and the connector pattern as the wafer is inserted into the connector.
Claims15
An apparatus for inserting a wafer onto plural connector pins of a connector having a wall portion with engagement features extending therefrom comprising:
- an alignment tube having a connector facing end, an opposing end and a side wall, said side wall having alignment tube features mateable with said connector wall engagement features;
- a keyway in said alignment tube side wall;
- a wafer plunger having a connector facing end, an opposing end and an external wall, said wafer plunger external wall carrying a keying block, said keying block being mateable with said keyway;
- a planar surface for receiving force at the opposing end of said wafer plunger;
- at least one prong extending from the connector facing end of said wafer plunger;
- a wafer retainer having a plunger facing end and a connector facing end, and having a substantially transparent internal core member;
- a notch in a wall portion of said wafer retainer, said notch being mateable with said prong for connecting said wafer retainer to said wafer plunger;
- a plurality of bores in said internal core member extending from the connector facing end of said wafer retainer towards said plunger facing end;
- two clips extending from the connector facing end of said wafer retainer, wherein a wafer is connectable to said wafer retainer by said clips;
- and
- wherein said wafer retainer and said wafer plunger are insertable into said alignment tube.

An apparatus for inserting a wafer onto plural connector pins of a connector having a wall portion with wall features extending therefrom comprising:
- a hollow cylinder shaped alignment tube having a connector facing end, an opposing end and a side wall;
- alignment tube features in said alignment tube side wall, said alignment tube features being mateable with said connector wall features;
- plural keyways in said alignment tube side wall;
- a circular lip at the opposing end of said alignment tube;
- a hollow right cylinder shaped wafer plunger having a connector facing end, an opposing end and an external wall,
- said wafer plunger external wall carrying plural keying blocks, said keying blocks being mateable with said keyways,
- said keyways and keying blocks being spaced so that said wafer plunger is mateable with said alignment tube in only one orientation;
- a ring shaped planar surface for receiving force at the opposing end of said wafer plunger;
- at least one prong extending from the connector facing end of said wafer plunger;
- a disk shaped wafer retainer having a plunger facing end and a connector facing end;
- a substantially transparent and planar internal core member in said wafer retainer;
- an external ring member surrounding said internal core member;
- a notch in a wall portion of said external ring member, said notch being mateable with said prong for connecting said wafer retainer to said wafer plunger;
- a plurality of bores in said internal core member extending from the connector facing end of said wafer retainer towards said plunger facing end;
- plural clips extending from the connector facing end of said wafer retainer, said clips being resiliently biased towards said internal core member;
- and
- wherein said wafer retainer and said wafer plunger are insertable into said alignment tube.

A three piece apparatus for inserting a thin, flat wafer having plural connector pin apertures arranged in a predetermined pin pattern into a plural pin connector in which the pins are arranged in the same predetermined pin pattern comprising:
- (1) a first piece comprising wafer retaining means including:
- (a) a flat surface adapted to contact the wafer to be inserted, said flat surface having plural connector pin apertures, arranged in the predetermined pin pattern of the connector into which the wafer is to be inserted, and
- (b) plural wafer edge contacting means for engaging the edge of a wafer when the wafer is in contact with said flat surface of the wafer retaining means with the apertures of the wafer to be inserted being in alignment with apertures in said flat surface;
- (2) a second piece comprising means for carrying said first piece in a unique alignment therewith;
- and
- (3) a third piece comprising:
- (a) means to removably mate said third piece with a connector into which the wafer is to be inserted in a unique alignment with respect to the connector, and
- (b) means for slidably receiving said second piece in a unique alignment therewith,
- the sliding movement of said second piece, and thus said first piece, in said third piece effects the insertion of a wafer when carried by said first piece into a connector with which said third piece is aligned with the apertures in the wafer aligned with the pins of the connector assured by the unique alignment of said three pieces.
