Liquid-tight, strain-relief connector for connecting conduit and the like

A liquid-tight, strain-relief connector for conduit, said connector comprising:

• (a) a substantially hollow body having a longitudinal axis, and front and rear portions spaced therealong;
• (b) a longitudinally adjustable sealing nut disposed between said front and rear portions, said sealing nut having internal threads corresponding to external threads on said body intermediate said front and rear portions, wherein longitudinal movement of said sealing nut is accomplished by rotation of said sealing nut relative to said front portion, and wherein said sealing nut further comprises an annular access oriented towards said front portion;
• (c) at least one resiliently compressible locking tab on said front portion of said body;
• (d) an elastomeric seal disposed adjacent at least partially said sealing nut whereby said seal is compressed between said recess, said bulkhead, and said body upon longitudinal movement of said sealing nut towards said front portion;
• (c) a cam surface located within the hollow body intermediate said front and rear portions;
• (d) a grip member having a ring-like base and a plurality of flexible gripping fingers cantilevered from said base, said base sized to slideably fit within said hollow body with said cantilevered fingers oriented along said longitudinal axis;
• (e) a seal member having a collapsible, flexible sealing end, said sealing end telescopically received within said grip member within said hollow body;
• and
• (f) a clamp nut which longitudinally telescopes over said rear portion of said hollow body by means of internal threads on said clamping nut corresponding to external threads on said rear portion of said body, said clamp nut further comprising a compression member which extends longitudinally into said hollow body, whereby longitudinal movement of said clamp nut by rotation of said clamp nut relative to said rear portion urges said gripping fingers against said cam surface, thereby collapsing said gripping fingers and said sealing end of said seal member radially inwardly.

A strain-relief, liquid tight connector for conduit said connector comprising:

• (a) a body having front and rear portions, a cam surface, and a substantially hollow inner throughbore formed along a longitudinal axis thereof;
• (b) means for attaching the front portion of the connector body to a bulkhead;
• (c) a flexible seal member for receiving a conduit, said seal member facilitating a substantially liquid tight seal about the conduit during use;
• (d) an at least partially hollow grip for selectively gripping the conduit, said seal member being located at least partially within said grip in use;
• and
• (e) a clamp nut telescoped over said rear portion of said body for selective longitudinal adjustment therealong, wherein said longitudinal adjustment of said clamp nut causes said cam surface to contact said grip to provide inward radial compression thereof.

• (a) a body having front and rear portions, and a substantially hollow inner throughbore formed along a longitudinal axis thereof;
• (b) means for attaching the front portion of the connector body to a bulkhead;
• (c) a flexible seal member mounted at least partially within said hollow inner throughbore for receiving a conduit to be connected, said seal member facilitating a substantially liquid tight seal about the conduit during use;
• (d) an at least partially hollow grip comprising a plurality of substantially rigid yet collapsible gripping fingers which are cantilevered from said rear portions of said body, and wherein each of said gripping fingers has a shoulder surface located thereon;
• and
• (e) a clamp nut having a cam surface and being telescoped over said rear portion of said body for selective longitudinal adjustment therealong, whereby longitudinal adjustment of said clamp nut urges said cam surface against said shoulder surfaces, thereby radially compressing said gripping fingers.

• (b) a longitudinally adjustable sealing nut disposed between said front and rear portions of said body;
• (c) an elastomeric member, whereby longitudinal adjustment of said sealing nut towards said front portions compresses said elastomeric member between said sealing nut and a bulkhead in use;
• (d) a flexible seal member mounted for receiving a conduit to be connected, said seal member facilitating a substantially liquid tight seal about the conduit during use;
• (e) an at least partially hollow grip for selectively gripping the conduit and
• (f) a clamp nut telescoped over said rear portion of said body for selective longitudinal adjustment therealong, wherein said longitudinal adjustment of said clamp nut provides inward radial compression of said grip.

A strain-relief, liquid tight connector for conduit, said connector comprising:

• (a) a body having front and rear portions, and a substantially hollow inner throughbore formed along a longitudinal axis thereof;
• (b) a cam surface positioned at least partially within said inner throughbore;
• (c) means for attaching the front portion of the connector body to a bulkhead;
• (d) a flexible seal member mounted at least partially within said hollow inner throughbore in use for receiving a conduit to be connected, said seal member facilitating a substantially liquid tight seal about the conduit during use;
• (e) an at lest partially hollow grip comprising a plurality of substantially rigid yet collapsible gripping fingers;
• and
• (f) a clamp nut telescoped over said rear portion of said body for selective longitudinal adjustment therealong, said seal member located at least partially within said grip, and wherein longitudinal adjustment of said clamp nut effectuates contact between said cam surface and said gripping fingers, thereby providing inward radial compression of said gripping fingers to grip the conduit.
