Abstract

A first guiding mechanism is formed by the interior shape of an engagement portion of a plug housing and the exterior shape of an engagement portion of a receptacle housing, to be guided and inserted into the engagement portion. A second guiding mechanism is formed by guide posts and guide holes. A third guiding mechanism is formed by the interior shape of the engagement portion of the receptacle housing and the exterior shapes of first multi core ferrules of the plug side optical connector, to be inserted into the engagement portion of the receptacle housing. A fourth guiding mechanism is formed by guide pins of second multi core ferrules and guide pin apertures, for receiving the guide pins of the first multi core ferrules. The first, second, third, and fourth guiding mechanisms operate in this order during engagement of a receptacle side optical connector and a plug side optical connector.

Claims

1. A multi core optical connect or assembly, comprising:

a plug side optical connector having a plug housing; and

a receptacle side optical connector having a receptacle housing that engages with the plug housing;

the plug housing having a plurality of first multi core ferrules and a forwardly facing guide post;

the receptacle housing having a plurality of second multi core ferrules and a guide post hole for receiving the guide post;

the first and second multi core ferrules holding the ends of optical fiber cables to be connected to each other;

a first guiding mechanism being formed by the interior shape of an engagement portion of the plug housing and the exterior shape of an engagement portion of the receptacle housing, which is to be guided and inserted into the engagement portion of the plug housing;

a second guiding mechanism being formed by the guide post and the guide hole;

a third guiding mechanism being formed by the interior shape of the engagement portion of the receptacle housing and the exterior shapes of the first plug side multi core ferrules, which are to be inserted into the engagement portion of the receptacle housing;

a fourth guiding mechanism being formed by guide pins of the first or second multi core ferrules and guide pin apertures, for receiving the guide pins, of the second or first multi core ferrules; and

the first, second, third, and fourth guiding mechanisms operating sequentially in number order during engagement of the receptacle side optical connector and the plug side optical connector.

2. A multi core optical connector assembly as defined in claim 1, wherein at least one of the plug housing and the receptacle housing further comprises a flexible tube mounted at a rear end thereof.

3. A multi core optical connector assembly as defined in claim 2, wherein the inner dimension of the tube is of a size that enables the multi core ferrules, to which the optical fiber cables are attached, and the bundled optical fiber cables to pass therethrough.

4. A multi core optical connector assembly as defined in claim 1, wherein the receptacle housing of the receptacle side optical connector further comprises a support member, for supporting the multi core ferrules.

5. A multi core optical connector assembly as defined in claim 4, wherein the support member comprises a support portion for supporting rear portions of the multi core ferrules, and arms that extends rearward from the support portion.

6. A multi core optical connector assembly as defined in claim 5, wherein engaging portions are formed on the arms, such that the engaging portions are engaged with the receptacle housing and are disengageable from the receptacle housing by flexure of the arms.

7. A multi core optical connector assembly as defined in claim 2, wherein the receptacle housing of the receptacle side optical connector further comprises a support member, for supporting the multi core ferrules.

8. A multi core optical connector assembly as defined in claim 7, wherein the support member comprises a support portion for supporting rear portions of the multi core ferrules, and arms that extends rearward from the support portion.

9. A multi core optical connector assembly as defined in claim 8 wherein engaging portions are formed on the arms, the engaging portions are engaged with the receptacle housing and are disengageable from the receptacle housing by flexure of the arms.

10. A multi core optical connector assembly as defined in claim 5, wherein the support portion of the support member is planar.

11. A multi core optical connector assembly as defined in claim 10, wherein the arms are formed as a pair extending from both sides of the support portion.

12. A multi core optical connector assembly as defined in claim 11, wherein the engaging portions are formed on each of the arms.

13. A multi core optical connector assembly as defined in claim 8, wherein the support portion of the support member is planar.

14. A multi core optical connector assembly as defined in claim 2, wherein the arms are formed as a pair extending from both sides of the support portion.

15. A multi core optical connector assembly as defined in claim 14, wherein the engaging portions are formed on each of the arms.
