Abstract
Abstract An electrical connector comprises an insulating housing having a plurality of contact openings extending therethrough. A contact is positioned within each of said openings, and a separate lid is removably mounted on the upper surface of said insulating housing. The lid is provided with a plurality of lead openings, each lead opening being in direct alignment with, and in communication with a corresponding contact opening in the insulating housing. An adapter for insulating the contacts of the electrical connector from a metal plate is comprised of a flat insulating member having an upper and a lower surface. A plurality of hubs are integrally molded with said lower surface and extend downwardly therefrom. A plurality of tail-receiving openings are provided in the adapter, each such opening extending through the upper surface of the flat insulating member and a respective hub to receive the tail portion of a contact therein. The flat insulating member also comprises a plurality of terminal openings adjacent the tail-receiving openings, each terminal opening being adapted to accommodate a portion of a terminal pin mounted in, and grounded to the metal plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
317 words
A connector for mounting, on a pierced plate, an electrical component comprising an insulator body having a plurality of leads extending therefrom in a common direction, said connector comprising: a. a unitary insulator housing having an upper surface, an opposed lower surface, and a plurality of contact openings extending therethrough from said upper surface to said lower surface, b. a plurality of separate, conductive, elongated contacts positioned in said openings of said housing, each of said contacts having a nose section adjacent said upper surface of said housing, a tail section adjacent said lower surface of said housing, and a body section, said body section containing (1) means for frictionally retaining said contact in said housing and (2) a first pair of shoulders, wider than said tail section and facing said tail section, for precluding downward withdrawal of said contact when said housing is mounted with its bottom surface adjacent a member having an opening, narrower than said shoulders, through which said tail section extends, said nose section of each contact having opposed yieldable arms for gripping a lead of said insulator body when said lead is inserted into one of said contact openings in said upper surface of said housing, c. A flat lid mounted adjacent said upper surface of said housing, said lid containing a plurality of lead openings extending therethrough and positioned in alignment with said contact openings of said housing, said lead openings of said lid being smaller than said contact opeNings of said housing and the front of said nose section of said contact, thereby to preclude withdrawal of said contact from said housing when said lid is mounted on said housing, and to permit removal and replacement of a single contact after removal of said lid, even though said housing is mounted on said plate and the tail portions of the other contacts in said housing are wired in a circuit.
Claim 2
Dependent Claim
317 words
A connector for mounting, on a pierced plate, an electrical component comprising an insulator body having a plurality of leads extending therefrom in a common direction, said connector comprising: a. a unitary insulator housing having an upper surface, an opposed lower surface, and a plurality of contact openings extending therethrough from said upper surface to said lower surface, b. a plurality of separate, conductive, elongated contacts positioned in said openings of said housing, each of said contacts having a nose section adjacent said upper surface of said housing, a tail section adjacent said lower surface of said housing, and a body section, said body section containing (1) means for frictionally retaining said contact in said housing and (2) a first pair of shoulders, wider than said tail section and facing said tail section, for precluding downward withdrawal of said contact when said housing is mounted with its bottom surface adjacent a member having an opening, narrower than said shoulders, through which said tail section extends, said nose section of each contact having opposed yieldable arms for gripping a lead of said insulator body when said lead is inserted into one of said contact openings in said upper surface of said housing, c. A flat lid mounted adjacent said upper surface of said housing, said lid containing a plurality of lead openings extending therethrough and positioned in alignment with said contact openings of said housing, said lead openings of said lid being smaller than said contact opeNings of said housing and the front of said nose section of said contact, thereby to preclude withdrawal of said contact from said housing when said lid is mounted on said housing, and to permit removal and replacement of a single contact after removal of said lid, even though said housing is mounted on said plate and the tail portions of the other contacts in said housing are wired in a circuit.
Claim 3
Dependent Claim
55 words
The connector of claim 1 wherein part of said nose section of each contact protrudes from said upper surface of said insulator housing, thereby to facilitate grasping of said nose section for withdrawal of said contact, and said lead openings of said lid have widened portions to accommodate the protruding portions of said nose sections.
Claim 4
Dependent Claim
53 words
The connector of claim 1 wherein said lid has a plurality of projections on the surface thereof adjacent said upper surface of said housing and said upper surface of said housing has a plurality of openings for receiving and frictionally engaging said projections of said lid to retain said lid on said housing.
Claim 5
Dependent Claim
108 words
The connector of claim 1 wherein the body section of each of said contacts also includes a second pair of shoulders facing the nose section of said contact and wherein each contact opening of said housing has a pair of shoulders facing said bottom surface of said housing for engaging said second pair of shoulders of said contact for preventing movement of said contact toward said upper surface of said housing, said second pair of shoulders of said contact only engaging part of said shoulders of said housing thereby to permit broaching of said housing shoulders upon removal of said contact through said upper surface of said housing
Claim 6
Dependent Claim
73 words
The connector of claim 4 wherein each of said contact openings in said insulator housing has a pair of grooves extending along respective opposed walls thereof from said upper surface to said lower surface, each of said grooves having a widened portion adjacent said bottom surface, the transition between said widened portion and the rest of each groove forming one of said pair of shoulders which face said bottom surface of said housing.
Claim 7
Dependent Claim
130 words
The connector of claim 1 further including an adapter comprising a flat insulating member having an upper surface and a lower surface, said lower surface having a plurality of hubs extending therefrom, each of said hubs being in alignment with a respective one of said contact openings in said housing and having an axial hole which extends through said adapter to said upper surface thereof, the upper surface of said adapter being positioned adjacent the lower surface of said housing such that the tail sections of said contacts extend through said axial holes in said adapter and engage said axial holes frictionally so as to retain said adapter to said housing, whereby said connector can be mounted on a pierced metal plate with said contacts insulated from said metal plate.
Claim 8
Dependent Claim
43 words
The connector of claim 6 further including a metal plate having a plurality of holes therein, said hubs on said adapter extending through said holes in said metal plate and frictionally engaging said holes so as to retain said adapter to said plate.
Claim 9
Dependent Claim
26 words
The connector of claim 7 wherein said adapter has a plurality of openings therein to accommodate the heads of ground terminals mounted on said metal plate.
Claim 10
Dependent Claim
56 words
The connector of claim 6 wherein the tail section of each of said contacts has a pair of opposed barbs thereon and each of said axial holes in said adapter has, adjacent the bottom surface of each of said hubs, a widened portion forming downwardly facing shoulders onto which the barbs of each contact can lock.
Claim 11
Dependent Claim
48 words
The connector of claim 1 wherein said opposed yieldable arms of said nose section of said contact extend from said body section in a direction normal to the direction of elongation of said contact, such that, in each contact, said nose section is offset from said body section.
