Sealing enclosure for a connector on a cable such as a standardized fiber-optic connector

A sealing assembly, the sealing assembly extending along an axis from a front end of the sealing assembly to a rear end of the sealing assembly, and comprising:

• a cable;
• a fiber optic connector positioned at a front end of the cable, the fiber optic connector including a ferrule terminating an optical fiber of the cable;
• a first body extending along the axis from a front end of the first body to a rear end of the first body, at least a portion of the fiber optic connector extending beyond the front end of the first body, the first body including:
• a tapered portion;
• a cable seal positioned in the tapered portion, the cable seal being adapted to sealingly engage the cable;
• a positive locking element configured to engage a positive locking element of a mating enclosure;
• and
• a cable receiving volume positioned in front of the cable seal;
• and
• a second body extending along the axis from a front end of the second body to a rear end of the second body, the second body being adapted to advance along the axis between a rearward position of the second body relative to the first body and a forwardmost position of the second body relative to the first body,
• wherein the sealing assembly is configured such that advancing of the second body forwardly to the forwardmost position without rotation of the second body about the axis causes the cable seal to compress radially towards the axis against the cable while a portion of the cable within the cable receiving volume remains loosely received within the cable receiving volume;
• and
• wherein in the forwardmost position, the first body extends forwardly beyond the front end of the second body.

An assembly, comprising:

• a mating enclosure including a fiber optic adapter and a first positive locking element;
• and
• a sealing assembly configured to sealingly mate with the mating enclosure, including:
• a cable;
• a fiber optic connector positioned at a front end of the cable, the fiber optic connector including a ferrule terminating an optical fiber of the cable;
• a first body extending along the axis from a front end of the first body to a rear end of the first body, at least a portion of the fiber optic connector extending beyond the front end of the first body, the first body including:
• a tapered portion;
• a cable seal positioned in the tapered portion, the cable seal being adapted to sealingly engage the cable;
• a second positive locking element configured to engage the first positive locking element of the mating enclosure;
• and
• a cable receiving volume positioned in front of the cable seal;
• and
• a second body extending along the axis from a front end of the second body to a rear end of the second body, the second body being adapted to advance along the axis between a rearward position of the second body relative to the first body and a forwardmost position of the second body relative to the first body,
• wherein the sealing assembly is configured such that advancing of the second body forwardly to the forwardmost position without rotation of the second body about the axis causes the cable seal to compress radially towards the axis against the cable while a portion of the cable within the cable receiving volume remains loosely received within the cable receiving volume;
• wherein in the forwardmost position, the first body extends forwardly beyond the front end of the second body;
• and
• wherein when the sealing assembly is sealingly mated with the mating enclosure, a portion of the first body is received in the mating enclosure and the connector is received in the fiber optic adapter.

A sealing assembly, the sealing assembly extending along an axis from a front end of the sealing assembly to a rear end of the sealing assembly, and comprising:

• a cable;
• a fiber optic connector positioned at a front end of the cable, the fiber optic connector including a ferrule terminating an optical fiber of the cable;
• a first body extending along the axis from a front end of the first body to a rear end of the first body, at least a portion of the fiber optic connector extending beyond the front end of the first body, the first body including:
• a tapered portion;
• a cable seal positioned in the tapered portion, the cable seal being adapted to sealingly engage the cable;
• a positive locking element including a groove configured to engage a positive locking element of a mating enclosure;
• and
• a cable receiving volume positioned in front of the cable seal;
• and
• a second body extending along the axis from a front end of the second body to a rear end of the second body, the second body being adapted to advance along the axis between a rearward position of the second body relative to the first body and a forwardmost position of the second body relative to the first body,
• wherein the sealing assembly is configured such that advancing of the second body forwardly to the forwardmost position without rotation of the second body about the axis causes the cable seal to compress radially towards the axis against the cable while a portion of the cable within the cable receiving volume remains loosely received within the cable receiving volume;
• wherein in the forwardmost position, the first body extends forwardly beyond the front end of the second body;
• and
• wherein the positive locking element of the first body is configured to prevent relative rotation between the first body and the mating enclosure when the positive locking element of the first body and the positive locking element of the mating enclosure are engaged with each other.
