Claims
- 1. An electrical connector, comprising:
- a rigid dielectric body,
- a molded tubular body of elastomeric dielectric having hollow interior provided with an integral web which is joined to said tubular body, said web having an initial configuration bridging across said hollow interior,
- said web having a central aperture therethrough,
- an electrical lead having a central conductor provided thereover with an insulation jacket,
- a portion of said conductor being received in the hollow interior of said tubular body,
- said tubular body yielding elastically radially outward upon receipt of said insulation jacket in the hollow interior thereof,
- said tubular body exerting a residual elastic radial grip on said insulation jacket to form a gas tight seal thereover,
- said electrical lead being received through the central aperture of said web,
- said web being stretched elastically to an elongate sleeve form encircling and elastically gripping a section of said insulation jacket to form a gas tight seal thereover,
- said sleeve form web extending longitudinally of said hollow interior of said tubular body,
- said tubular body elastically yielding radially outward to accommodate said sleeve form web,
- said tubular body forming a gas tight sheath intimately and compressibly encircling the length of said sleeve form web and a longitudinal section of said insulation jacket which is disposed in said tubular body and which is immediately adjacent said sleeve form web,
- said sleeve form web being radially in compression externally by said tubular body and internally by said insulation jacket to prevent reformation of said sleeve form web to its original configuration,
- said rigid dielectric body including a hollow interior,
- a wall internally of said dielectric body and extending transversely of said hollow interior thereof,
- a boss integral with said wall and projecting concentrically within said hollow interior,
- said boss having a concentric bore therethrough communicating with a forward end portion of said rigid dielectric body,
- a forward end portion of said tubular body yieldably elastically engaged in the hollow interior of said rigid dielectric body forming a gas tight seal therewith,
- said forward end of said tubular body encircling said boss to form a gas tight seal therewith,
- said conductor of said electrical lead being connected to an electrical terminal mounted in said bore of said boss, and
- means securing together said tubular body and said rigid dielectric body.
- 2. The structure as recited in claim 1, and further including:
- an external radial flange integral with said tubular body and providing a relatively thick radial section of elastomeric material overyling a junction of said web and said tubular body,
- said relatively thick radial section yielding elastically to stress relieve said junction when said web is stretched to said sleeve form,
- a flange being engaged against a rearward end portion of said rigid dielectric body.
- 3. The structure as recited in claim 1, wherein, said sleeve form web is elastically folded at one end which is joined integral with said tubular body and includes an opposite free end thereof extended longitudinally toward said forward end of said tubular body, said tubular body compressing said folded one end substantially eliminating any space between said tubular body and said folded one end.
- 4. The structure as recited in claim 3, wherein, said tubular body includes an integral external radial flange providing a thickened radial section of elastomeric material overlying said folded one end of said tubular body and which yields elastically to relieve the deformation stress at a junction of said sleeve form web and said tubular body.
- 5. The structure as recited in claim 4, wherein, said forward end of said tubular body includes a plurality of spaced integral external ribs which yield elastically in engagement against said hollow interior of said rearward end of said rigid dielectric body,
- and further including: a spaced defined between said external flange and one of said external ribs, said section of said tubular body which overlies said sleeve form web yielding elastically and expanding radially outward into said space to relieve deformation stresses within itself.
- 6. The structure according to claim 4, wherein, said flange elastically yields radially outward to encircle said web in its elastically stretched sleeve form concentric with said flange.
- 7. The structure according to claim 6, wherein, said web in said sleeve form has a free end extending longitudinally forwardly of said flange, said tubular body radially outwardly yielding immediately adjacent said flange.
- 8. The structure according to claim 1 further comprising:
- an interfacial seal having outer and inner concentric cylindrical members integrally joined at one end by a radial web, said outer cylindrical member being received in the hollow interior of said rigid dielectric body, said electric terminal passing through said inner cylindrical member, and a mating connector member being received between said cylindrical members in compression thereby forming gas tight seals therebetween.
- 9. The structure according to claim 8 further comprising:
- a rearwardly directed, frusto-conical entry to said inner cylindrical member, and
- said seal is made of compliant dielectric material requiring little force to effect great distortion.
