Abstract

Abstract An electrical connector for attaching wires extending from a patient to an extra-corporeal medical instrument - resilient electrically conductive jaws grip an axially inserted wire leading from the patient. A collet peripherally mounted on the jaws adjustably deforms them exerting a compressive clamping force on the wire. The collet and jaw assembly is appropriately keyed to a complementary aperture in the instrument panel and affixed thereto by a threaded locking member. The locking member is electrically conductive thereby forming a feed through of the instrument panel. As the locking member engages a complementary threaded portion on the distal end of the jaws a bearing force is applied thereby affixing the entire assembly to the panel.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 303 words
An electrical connector adapted for high reliability operation in medical electronics usage to couple electrical conductor leads having cylindrical surfaces from instruments sensing bodily conditions to an instrument panel having apertures said connector comprising: a multi-jawed connector member having an internal, axially aligned bore therethrough, said jaws being formed by radial axially aligned slots extending a substantial portion of the axial extent of said connector member, said member having a wire receiving end and a panel terminating end, said member at said wire receiving end having a substantially frustoconical external surface and said bore having a substantially cylindrical surface, said terMinating end including first means for keying said connecting member into one of said apertures of said panel to prevent relative rotatary motion of said connector in said panel or said wire during connection; a collet member adapted to be received over said connector member, said collet member having an axial bore therethrough complementary to said connector member at one end and adapted at said other end with a frusto-conical surface complementary to the frusto-conical surface of said connector member whereby rotary movement of said collet member causes relative axial movement of said collet member toward said connector member and panel to cause said substantially cylindrical surface of said bore to mate with and close on a length of said cylindrical wire equal to a considerable portion of said axial extent and make a secure electrical and mechanical connection therewith, said collet member including a first member including second keying means adapted to cooperate with said first keying means of said connector member, preventing relative rotary motion of said conductor and said connector member, and a second member threadingly engaged with said first member, said second member including said frusto-conical bore and adapted to be received over said connector and said first member.
Claim 2
Dependent Claim 303 words
An electrical connector adapted for high reliability operation in medical electronics usage to couple electrical conductor leads having cylindrical surfaces from instruments sensing bodily conditions to an instrument panel having apertures said connector comprising: a multi-jawed connector member having an internal, axially aligned bore therethrough, said jaws being formed by radial axially aligned slots extending a substantial portion of the axial extent of said connector member, said member having a wire receiving end and a panel terminating end, said member at said wire receiving end having a substantially frustoconical external surface and said bore having a substantially cylindrical surface, said terMinating end including first means for keying said connecting member into one of said apertures of said panel to prevent relative rotatary motion of said connector in said panel or said wire during connection; a collet member adapted to be received over said connector member, said collet member having an axial bore therethrough complementary to said connector member at one end and adapted at said other end with a frusto-conical surface complementary to the frusto-conical surface of said connector member whereby rotary movement of said collet member causes relative axial movement of said collet member toward said connector member and panel to cause said substantially cylindrical surface of said bore to mate with and close on a length of said cylindrical wire equal to a considerable portion of said axial extent and make a secure electrical and mechanical connection therewith, said collet member including a first member including second keying means adapted to cooperate with said first keying means of said connector member, preventing relative rotary motion of said conductor and said connector member, and a second member threadingly engaged with said first member, said second member including said frusto-conical bore and adapted to be received over said connector and said first member.
Claim 3
Dependent Claim 23 words
The connector of claim 1 wherein said frusto-conical surfaces are disposed at an angle of approximately 15* to the axis of said cone.
Claim 4
Dependent Claim 16 words
The connector of claim 2 wherein said connector and keying means are of electrically conductive material.
Claim 5
Dependent Claim 17 words
The connector of claim 3 wherein said first and second collet members are of electrically insulative material.
Claim 6
Dependent Claim 21 words
The connector of claim 4 wherein said channel may receive said wire having a diameter between approximately 0.040 and 0.125 inches.
