Abstract

An optical fiber connector assembly includes a first connector and a second connector. The first connector includes two pairs of first convex lenses projecting from a front mating face thereof and a pair of cone-shaped positioning posts at sides of the pairs of convex lenses respectively. The second connector includes two pairs of second convex lenses projecting from a second front mating face thereof to couple with the first convex lenses and a pair of positioning holes to be inserted with the positioning posts of the first connector. Each of the positioning holes includes a retention section and a guiding section in front of the retention section, and the retention sections is same to the positioning posts while the guiding sections is larger than the position posts in dimension.

Claims

1. An optical fiber connector assembly comprising:

a first connector comprising two pairs of first convex lenses projecting from a front mating face thereof and a pair of cone-shaped positioning posts at sides of the pairs of convex lenses respectively;

a second connector comprising two pairs of second convex lenses projecting from second front mating face thereof to couple with the first convex lenses and a pair of positioning holes to be inserted with the positioning posts of the first connector;

wherein each of the positioning holes comprises a retention section and a guiding section in front of the retention section, the retention sections is same to the positioning posts while the guiding sections is larger than the position posts in dimension.

2. The optical fiber connector assembly as claimed in claim 1, wherein the guiding sections start from the front mating face of the first connector.

3. The optical fiber connector assembly as claimed in claim 2, wherein the positioning holes are of a cone shaped.

4. The optical fiber connector assembly as claimed in claim 3, wherein the first and the second defines grooves at rear portions thereof to hold corresponding optical fibers, respectively.

5. The optical fiber connector assembly as claimed in claim 4, wherein a front face from which the positioning posts extends and a front face of the positioning hole are located forward beyond the front mating faces of the lenses.

6. The optical fiber connector assembly as claimed in claim 5, wherein a mating space is defined between the first and second connector coupled to each other.

7. An electrical connector assembly comprising:

a first optical module for use within a first connector, and a second optical module for use within a second connector, said first optical module and said second optical module being mateable with each other,

said first optical module defining a plurality of first convex lenses, said second optical module defining a plurality of second convex lenses in respective intimate alignment with the corresponding first convex lenses during mating;

the first optical module defining a pair of cone-shaped positioning posts, and the second optical module defining a pair of positioning holes for coupling to the corresponding positioning posts, respectively, during mating;

wherein each of the positioning holes defines a front guiding section with a large tapered angle, and a rear retention section with a small tapered angle.

8. The electrical connector assembly as claimed in claim 7, wherein the positioning post essentially defines a constant tapered angle which is similar to that of the retention section of the corresponding positioning hole.

9. The electrical connector assembly as claimed in claim 7, wherein said positioning hole communicates with an exterior not only axially but also diametrically on two opposite segments of a circumference thereof.
