Abstract
Abstract A shell for a connector for flat shielded cable. The shell is formed of conductive material and is constructed so as physically and electrically to contact the shield so that grounding the shell will ground the shield. The shell also includes portions to grip firmly the cable so as to relieve strain from the cable-connector connection. Finally the shell defines a cavity for the connector; the cavity has one or more irregularities corresponding to mirror image irregularities in the connector cavity to assure proper positioning of the connector within the shell cavity. Associated with the receptacle adapted to receive the connector are two toggle latches; the shell is provided with external hooks adapted to cooperate with the toggle latches so as to achieve firm connection between the connector and the receptacle as well as connection of the shell to ground.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
259 words
A connector shell for a shielded flat cable termination comprising first and second complemental matable members formed of rigid electrically conductive material, means for joining said members in assembled relation on a parting plane, said members defining a cable end and a connector end opposite from said cable end, said members forming a continuous passage through said connector shell between said ends, said passage adjacent said cable end defining strain relief means, said strain relief means including a plurality of ribs oriented transversely of said passage projecting inward of each said member, respective said ribs being transversely aligned and having confronting edge lines confronting each other in spaced apart relation by a distance such as to grip flat shielded cable therebetween, said connector having inward of said strain relief means a region constituting shield contacting means, said shield contacting means including first and second arrays of spaced apart generally conical protuberances extending into said passages from respective said members, the inner extremities of said conical protuberances extending beyond said parting plane and said arrays being offset from one another so that the protuberances in one array reside in the spaces between protuberances in the other array thereby to establish firm electrical continuity between said members and the shield in said cable, said shell also defining adjacent said connector end a cavity in said passage for a flat cable connector, said cavity being substantially symmetrical of said parting plane and being sized to receive a connector therein so that the contacts in the connector are accessible through said connector end.
Claim 2
Dependent Claim
259 words
A connector shell for a shielded flat cable termination comprising first and second complemental matable members formed of rigid electrically conductive material, means for joining said members in assembled relation on a parting plane, said members defining a cable end and a connector end opposite from said cable end, said members forming a continuous passage through said connector shell between said ends, said passage adjacent said cable end defining strain relief means, said strain relief means including a plurality of ribs oriented transversely of said passage projecting inward of each said member, respective said ribs being transversely aligned and having confronting edge lines confronting each other in spaced apart relation by a distance such as to grip flat shielded cable therebetween, said connector having inward of said strain relief means a region constituting shield contacting means, said shield contacting means including first and second arrays of spaced apart generally conical protuberances extending into said passages from respective said members, the inner extremities of said conical protuberances extending beyond said parting plane and said arrays being offset from one another so that the protuberances in one array reside in the spaces between protuberances in the other array thereby to establish firm electrical continuity between said members and the shield in said cable, said shell also defining adjacent said connector end a cavity in said passage for a flat cable connector, said cavity being substantially symmetrical of said parting plane and being sized to receive a connector therein so that the contacts in the connector are accessible through said connector end.
Claim 3
Dependent Claim
69 words
A connector shell in accordance with claim 1 wherein said shell defines at said connector end a substantially planar surface oriented transversely of said passage, a substantially continuous rib projecting from said planar surface and circumscribing said connector end, said rib defining a planar surface extending substantially transversely of said passage and adapted for substantially continuous contact with a conductive gasket surrounding a receptacle with which said connector connects.
Claim 4
Dependent Claim
41 words
A connector shell in accordance with claim 1 wherein the connector has a surface defining at least one irregularity, said shell cavity having a mirror image irregularity for engaging said connector irregularity and securing said connector substantially immovably within said shell.
Claim 5
Dependent Claim
61 words
A connector shell in accordance with claim 1 wherein said shell defines exteriorly thereof first and second transversely opposite hook portions, and having in combination a receptacle for effecting connection with said connector and first and second toggle latches fixed at opposite extremities of said receptacle, each said toggle latch having a bail for removably engaging a respective said hook portion.
Claim 6
Dependent Claim
50 words
A connector shell in accordance with claim 4 wherein said receptacle has a polarizing excision at a marginal portion thereof and wherein said one of said shell members includes a protruding key engageable with said excision to effect correct polarization of the connector in said connector shell and said receptacle.
Claim 7
Dependent Claim
118 words
A connector shell in accordance with claim 4 including a mounting body for supporting at least one receptacle, said mounting body defining a substantially planar conductive surface circumscribing said receptacle, first and second mounting blocks rigid with said mounting body for supporting respective said toggle latches, said mounting blocks protruding from said planar surface and being spaced from said receptacle to define an uninterrupted margin circumscribing said receptacle, said mounting blocks defining respective side surfaces perpendicular to said planar surface and parallelly confronting one another on opposite sides of said receptacle, a conductive gasket dimensioned to reside between said side surfaces in contact with said planar surface, said gasket defining an opening for affording access to said receptacle.
Claim 8
Dependent Claim
56 words
A connector shell in accordance with claim 6 wherein said mounting body defines first and second surface portions substantially perpendicular to said planar surface and adjacent respective said mounting blocks, said surface portions cooperating with said toggle latches for limiting movement thereof to an over-the-center position to retain said connector shell in contact with said gasket.
