Arrangement for alignedly coupling two coated light-conductive fibers

An apparatus for aligning and coupling two coated light-conductive fibers, comprising a first guide member having a channel to support a first fiber to be coupled to a second fiber, a second guide member having a channel to support an end of the second fiber, said channel including a first section of a relatively large diameter, an intermediate section of a relatively small diameter to receive a stripped end portion of the second fiber and a third section coordinated to the diameter of the coated light-conductive second fiber;

• at least three clamping rods inserting into a space provided in said first guide member and partially extending into said first section of said second guide member, said clamping rods being arranged to engage the abutted stripped end portions of said fibers;
• a protective socket surrounding said second guide member and having an opening at one end thereof to receive said second coated light-conductive fiber, and deflectable means encompassing said clamping rods to maintain said clamping rods in clamping contact with said stripped end portions, said deflectable means being positioned on said clamping rods substantially at the middle thereof and including two rings positioned in spaced relationship and a resilient O-ring interposed therebetween, said second guide member being connected to the first guide member and arranged to connect the channel formed in the first guide member to the channel formed in the second guide member thereby providing radial forces for pressing said deflectable means inwardly into contact with said clamping rods to hold said stripped end portions in aligned and abutting position.

An apparatus for aligning and coupling two coated light-conductive fibers, comprising a first guide member having a first channel to support a first fiber to be coupled to a second fiber, a second guide member having a second channel to support a second fiber, each of said channels respectively including a first section of a relatively large diameter, an intermediate section of a relatively small diameter to receive a stripped end portion of the respective fiber and a third section coordinated to the diameter of the coated light-conductive respective fiber;

• an intermediate guide member adapted to be coupled between said first guide member and said second guide member and including a first element and a second element connectable to said first element;
• said first and second elements each being formed with a recess and with an opening to receive the respective fibers, the opening of said first element being aligned in assembly with the opening of said second element;
• a first set of at least three clamping rods inserted into the opening of said first element and partially extending into the first section of said first guide member and arranged to engage the abutted stripped end portions of said fibers;
• a second set of at least three clamping rods for guiding an end portion of said second fiber, said second set of the clamping rods being inserted into the opening of said second element and partially extending into the first section of said second guide member;
• a first protective socket surrounding said first guide member and adapted to receive the first fiber therethrough;
• a second protective socket surrounding said second guide member and adapted to receive the second fiber therethrough;
• first deflectable means encompassing said first set of the clamping rods to maintain the clamping rods in clamping contact with said stripped end portions, said first deflectable means being positioned in the recess of said first element and including two rings positioned in spaced relationship and a resilient O-ring interposed therebetween;
• and second deflectable means encompassing said second set of the clamping rods to maintain the clamping rods in clamping contact with the second fiber, said second deflectable means being positioned in the recess of said second element and including two rings positioned in spaced relationship and a resilient O-ring interposed therebetween, said first guide member being connected to said first element and said second guide member being connected to said second element while said first element is connected to said second element so that in assembly said first channel, said first opening, said second opening and said second channel will be aligned with each other to receive respective end portions of the fibers to be coupled and radial forces will be provided for pressing said first and second deflectable means inwardly into contact with the respective clamping rods to hold said stripped end portions in aligned and abutting position.
