SEALING ENCLOSURE FOR A CONNECTOR ON A CABLE SUCH AS A STANDARDIZED FIBER-OPTIC CONNECTOR

摘要

A sealing enclosure is configured to connect to a mating enclosure. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. The connector may compensate variations in the position of a mating connector with respect to the mating enclosure. The sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.

主权项

1. A sealing enclosure comprising:
a fiber optic connector adapted to be mounted on an end of a cable; an inner body having a connector volume, the fiber optic connector being received within the connector volume, the inner body including a plug section having a forward facing plug face that is open in a forward direction, the plug section including at least one positive locking element; an outer body surrounding the inner body and being movable relative thereto, the outer body having a bayonet-type locking element at a forward end of the outer body, the bayonet-type locking element being provided on an interior side of the outer body facing the plug section; and a mating section provided with at least one locking element that matches the bayonet-type locking element of the outer body to enable a bayonet-type locking with the outer body, the mating section also including a positive locking element that engages with the at least one positive locking element of the plug section to prevent relative rotation between the inner body and the mating section, the mating section including an annular collar having an annular seal on an outer circumference thereof for providing a seal between the mating section and the outer body; wherein the inner body includes a rearwardly facing shoulder, and wherein the outer body includes an abutment surface that faces the rearwardly facing shoulder in an axial direction; wherein a spring element is positioned between the rearwardly facing shoulder and the abutment surface; and wherein an annular seal positioned rearward of the spring element is provided for sealing between the inner body and the outer body.
