Connector with vibration tolerance
A connector having a front and rear origination and configured to mate with a mating connector, and including a housing having one or more cavities defined therein, and having a front face with one or more orifices defined therein, wherein each of the orifices corresponds to one of the cavities and has an inner first diameter. The connector further has an optical contact at least partially disposed in one of the cavities, and comprising at least a ferrule extending from the cavity and through the orifice corresponding to the cavity, the ferrule having a second diameter less than the first diameter such that a gap is defined between the ferrule and the housing at the orifice. Finally, the connector includes a compliant member disposed at least partially in the gap and configured to suppress vibration between the housing and the optical.
1. A connector having a front and rear origination and configured to mate with a mating connector, said connector comprising:
a housing having one or more cavities defined therein, and having a front face with one or more orifices defined therein, wherein each of said orifices corresponds to one of said cavities and has an inner first diameter;
an optical contact at least partially disposed in one of said cavities, and comprising at least a ferrule extending from said cavity and through the orifice corresponding to said cavity, said ferrule having a second diameter less than said first diameter such that a gap is defined between said ferrule and said housing at said orifice; and
a compliant member disposed at least partially in said gap and configured to suppress vibration between said housing and said optical contact.
2. The connector of claim 1 , wherein said compliant member is a compliant sleeve around said ferrule.
3. The connector of claim 1 , wherein said compliant member is a compliant grommet inserted in said orifice.
4. The connector of claim 1 , wherein a space exists either between said compliant member and said ferrule or between said compliant member and said orifice.
5. The connector of claim 4 , wherein said space exists between said compliant member and said orifice.
6. The connector of claim 1 , wherein said compliant member comprises rubber or PTFE.
7. The connector of claim 6 , wherein said compliant member has an elastic modulus of about 0.01 to about 0.5 GPa.
8. The connector of claim 1 , wherein said compliant member is annular and has a wall thickness between 0.10 mm and 0.18 mm when mounted on a 1.25 mm diameter ferrule.
9. The connector of claim 1 , wherein each of said cavities has an axis, and wherein said gap and said compliant member are configured such said ferrule is free to move within said orifice angularly and laterally with respect to said axis.
10. The connector of claim 1 , wherein said second diameter is constant along the length of said ferrule.
11. The connector of claim 1 , further comprising:
a sleeve disposed around a portion of said ferrule, said sleeve disposed in front of said front face and extending from a point forward of compliant member.
12. The connector of claim 11 , further comprising a lens disposed at least partially in said sleeve and forward of said front face.
13. The connector of claim 12 , wherein said lens is a ball lens.
14. The connector of claim 13 , wherein said ball lens contacts said fiber.
15. The connector of claim 11 , wherein said first diameter of said orifice is about the same as the outer diameter of said sleeve.
16. The connector of claim 11 , further comprising an outer sleeve configured to receive said sleeve.
17. The connector of claim 1 , further comprising:
a ferrule holder having a front end connected to said ferrule behind said orifice.
18. The connector of claim 1 , wherein said ferrule defines at least one borehole for receiving a fiber, and at least one fiber is disposed in said borehole.
