Abstract
Abstract A connector in accordance with the present invention comprises a dielectric contact carrier including a multiplicity of orifices extending from the front to the rear thereof in which a multiplicity of contact spring assemblies are respectively mounted. The free ends of the spring contacts are bent over so that they extend rearwardly cantilever fashion beneath the carrier and a wedge shaped latch extends upwardly from the carrier. The carrier is accommodated by an opening in the rear of a dielectric support, the opening leading to a carrier receiving cavity in the upper portion of the support and the upper surface of the cavity including a recess for accommodating the latch of the carrier. The support further includes a plug receiving cavity open to the front of the support that is situated beneath the carrier receiving cavity, and a slotted wall for constraining the free ends of the cantilever portions of the spring contacts is located at the rear of the plug receiving opening. The open ends of the slots are adjacent to the carrier receiving opening, and the slots are equal in number to the wire spring contacts and laterally spaced the same distance apart as the fixed ends of the cantilever portions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
357 words
A connector comprising: a dielectric contact carrier having locating means extending along at least one side thereof and a latch extending upwardly therefrom, the latch comprising a rigid protuberance, the trailing surface of which extends transversely to the top of the carrier to provide a blocking surface; a plurality of spaced spring contacts mounted on the carrier, each spring contact including a cantilever portion extending beneath the carrier; a dielectric support having a cavity into which the carrier is inserted, the upper surface of the cavity including a recess for accommodating the latch when the carrier is fully inserted into the cavity and the side of the cavity including locating means complementary to the locating means of the carrier for cooperating with the locating means of the carrier, both locating means including a first surface that is positioned adjacent to the first surface of the other locating means when the carrier is fully inserted into the cavity, and one locating means including a second surface that is opposed to the first surface thereof and extends along its length at an acute angle to the first surface, the spacing between the first and second surfaces being such as to permit the carrier to be deflected transversely to its direction of insertion, the support further including an integral contact engaging surface located so as to deflect the cantilever portions of the spring contacts upward when the carrier is fully inserted into the cavity, and the entrance of the cavity including means adjacent to the latch receiving recess for cooperating with the latch to deflect the carrier transversely to its direction of insertion so as to move the cantilever portions of the contact springs into engagement with the contact engaging surface, the cantilever portions of the spring contacts biasing the carrier so as to move the latch into the latch receiving recess when the carrier is fully inserted into the cavity, the latch receiving recess including a blocking surface extending generally parallel to and in juxtaposition with the blocking surface of the latch for cooperating therewith to prevent rearward movement of the carrier and thereby secure the carrier in place.
Claim 2
Dependent Claim
357 words
A connector comprising: a dielectric contact carrier having locating means extending along at least one side thereof and a latch extending upwardly therefrom, the latch comprising a rigid protuberance, the trailing surface of which extends transversely to the top of the carrier to provide a blocking surface; a plurality of spaced spring contacts mounted on the carrier, each spring contact including a cantilever portion extending beneath the carrier; a dielectric support having a cavity into which the carrier is inserted, the upper surface of the cavity including a recess for accommodating the latch when the carrier is fully inserted into the cavity and the side of the cavity including locating means complementary to the locating means of the carrier for cooperating with the locating means of the carrier, both locating means including a first surface that is positioned adjacent to the first surface of the other locating means when the carrier is fully inserted into the cavity, and one locating means including a second surface that is opposed to the first surface thereof and extends along its length at an acute angle to the first surface, the spacing between the first and second surfaces being such as to permit the carrier to be deflected transversely to its direction of insertion, the support further including an integral contact engaging surface located so as to deflect the cantilever portions of the spring contacts upward when the carrier is fully inserted into the cavity, and the entrance of the cavity including means adjacent to the latch receiving recess for cooperating with the latch to deflect the carrier transversely to its direction of insertion so as to move the cantilever portions of the contact springs into engagement with the contact engaging surface, the cantilever portions of the spring contacts biasing the carrier so as to move the latch into the latch receiving recess when the carrier is fully inserted into the cavity, the latch receiving recess including a blocking surface extending generally parallel to and in juxtaposition with the blocking surface of the latch for cooperating therewith to prevent rearward movement of the carrier and thereby secure the carrier in place.
Claim 3
Dependent Claim
323 words
A connector comprising: a dielectric contact carrier having a tongue extending along each side thereof and a latch extending upwardly therefrom, the latch comprising a protuberance having a wedge-shaped profile, the trailing surface of the latch extending approximately perpendicular to the top of the carrier to provide a blocking surface and the leading surface of the latch being inclined to the top of the carrier to provide a cam surface; a plurality of spaced spring contacts mounted on the carrier each spring contact including a cantilever portion extending beneath the carrier; a dielectric support having a cavity for receiving the carrier, the upper surface of the cavity including a recess for accommodating the latch when the carrier is fully positioned within the cavity and the side of the cavity including opposed grooves for accommodating the tongues of the carrier, the grooves tapering toward the front of the cavity, the support further including a plurality of spaced slots, the upper ends of which are open and are situated adjacent to the carrier receiving cavity, each slot accommodating the cantilever portion of an individual spring contact and including a contact engaging surface located so as to deflect the associated cantilever portion upward when the carrier is fully positioned within the cavity, and the entrance of the cavity including a cam surface adjacent to the latch receiving recess for cooperating with the cam surface of the latch to deflect the carrier toward the contact engaging surfaces of the slots as the carrier is inserted into the cavity, the cantilever portions of the spring contacts biasing the carrier so as to move the latch into the latch receiving recess when the carrier is fully positioned within the cavity, the latch receiving recess including a blocking surface extending generally parallel to and in juxtaposition with the blocking surface of the latch for cooperating therewith to prevent rearward movement of the carrier and thereby secure the carrier in place.
