Abstract
Abstract A pin loading system to load wire wrap pins into a master interconnect bo. A loading fixture includes a rod positioned within a wedge formed by the inclined interiors of a pair of abutting clamps. Its height therein may be varied by adjustment of a pair of knobs, allowing the alternative loosening and securing of pins to be mounted to a board. A shim placed below the fixture during the wave soldering process assures resilient pin connection.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
199 words
A loading system for loading at least one contact pin onto a board having an upper side and a lower side and having at least one mating hole therefor which system comprises: a. at least one elongated clamp rotatably mounted about its longitudinal axis having end portions with a notch therein and an outwardly inclined inner cross-section, and having an interior portion of lesser height than said end portions to allow for exposure of a contact pin common rail attached to said at least one contact pin for removal tool access; b. an elongated spacer having a rectangular interior portion and T-shaped end portions, at least one arm of said T-shaped end portions being pivotally engaged to said at least one elongated clamp; c. an elongated cylindrical rod in abutting relationship with said outwardly inclined inner cross-section; and e. elevation means to adjust the location of said rod relative to said outwardly inclined inner cross-section so that said at least one elongated clamp rotates about said longitudinal axis with the lower edge of said at least one elongated clamp forcefully engaging said at least one contact pin to hold said at least one contact pin within said loading system.
Claim 2
Dependent Claim
199 words
A loading system for loading at least one contact pin onto a board having an upper side and a lower side and having at least one mating hole therefor which system comprises: a. at least one elongated clamp rotatably mounted about its longitudinal axis having end portions with a notch therein and an outwardly inclined inner cross-section, and having an interior portion of lesser height than said end portions to allow for exposure of a contact pin common rail attached to said at least one contact pin for removal tool access; b. an elongated spacer having a rectangular interior portion and T-shaped end portions, at least one arm of said T-shaped end portions being pivotally engaged to said at least one elongated clamp; c. an elongated cylindrical rod in abutting relationship with said outwardly inclined inner cross-section; and e. elevation means to adjust the location of said rod relative to said outwardly inclined inner cross-section so that said at least one elongated clamp rotates about said longitudinal axis with the lower edge of said at least one elongated clamp forcefully engaging said at least one contact pin to hold said at least one contact pin within said loading system.
Claim 3
Dependent Claim
120 words
A loading system as described in claim 1 wherein said elevation means comprises: a. a pair of interiorly threaded knobs, each of said knobs located at one of opposite ends of said elongated rod; b. a pair of threaded studs, each fitted into one of opposite end portions of said spacer; c. said rod having holes passing through each of opposite ends thereof; d. each of said studs passing through each of said holes in said rod; and e. each of said knobs threaded onto each of said stubs whereby the loosening and tightening of said knobs on said stubs causes the abutting relationship of said elongated rod and said at last one elongated clamp to be tightened and loosened.
Claim 4
Dependent Claim
23 words
A loading system as described in claim 2 wherein each of said knobs is of circular cross section and has a flat top.
Claim 5
Dependent Claim
83 words
A loading system as recited in claim 3 further comprising a flat shim having an upper side and a lower side for spacing said at least one elongated clamp and at least one contact pin from said upper side of said board, and having a longitudinal extension which protrudes when said flat shim is located between said top side of said board and at least one elongated clamp, said longitudinal extension having a hole therein for attachment and use of a removal tool.
Claim 6
Dependent Claim
27 words
A loading system as described in claim 4 wherein there exists at least one notch interior to said T section for the insertion of a rail-stripping tool.
Claim 7
Dependent Claim
16 words
A loading system as described in claim 5 wherein said shim is fabricated of stainless steel.
Claim 8
Dependent Claim
17 words
A loading system as described in claim 6 wherein said retaining means is fabricated of stainless steel.
