Abstract

A locking mechanism of an optical module, which is mounted on a communication apparatus, to lock the optical module includes a locking member which includes a locking pawl fitted into a locking ditch formed on the communication apparatus, and a rocking pin that is attached at a position between the guide part and the locking pawl; a locking lever which includes a lock releasing pawl that fits the guide part, and a finger stopping part that has a ring shape; and a handle which includes, a grip part that has a shape of a ring, wherein the handle is fixed on a base which is a main part of the optical module; and wherein the grip part has the ring shape which is larger adequately in size than the finger stopping part, and protects the finger stopping part,

Claims

1. A locking mechanism of an optical module, which is mounted on a communication apparatus, to lock the optical module, comprising:

a locking member which includes

a locking pawl that is formed on a front end position of the locking member and is fitted into a locking ditch formed on the communication apparatus,

a guide part that is formed on a rear end position of the locking member, and

a rocking pin that is attached at a position between the guide part and the locking pawl;

a locking lever which includes

a lock releasing pawl that is formed on a front end position of the locking lever and fits the guide part, and

a finger stopping part that is formed on a rear end position of the locking lever and has a ring shape, wherein

the locking lever is energized in the forward direction by a spring; and

a handle which includes

a grip part that has a shape of a ring, wherein

the handle is fixed on a base which is a main part of the optical module; and

wherein

the grip part has the ring shape which is larger adequately in size than the finger stopping part, and protects the finger stopping part.

2. The locking mechanism of the optical module according to claim 1, wherein

the guide part includes a virtually triangular pole projecting in a width direction from an end area of the locking lever, wherein

the triangular pole has one surface, which is parallel with a moving surface of the locking lever, and has a guide surface, which inclines a downward direction to the moving surface, and

the lock releasing pawl includes a slide surface opposite to the guide surface;

wherein

the locking member rocks around the rocking pin to make the locking pawl left from the locking ditch when the slide surface being guided along the guide surface according to the locking lever, which is moved in the backward direction.

3. The locking mechanism of the optical module according to claim 1, wherein

the locking lever includes a lock holding part at a position apart from the guide part by a predetermined distance in the backward direction, and wherein

the lock holding part touches a rear end of the locking member to restrain the locking member from rocking when the locking lever is moved in the forward direction by force of the spring.

4. The locking mechanism of the optical module according to claim 3, wherein

the lock holding part is a tapered surface.

5. The locking mechanism of the optical module according to claim 1, wherein

the locking member is formed by the sheet metal work.

6. A locking mechanism of an optical module, which is mounted on a communication apparatus, to lock the optical module, comprising:

a locking member means which includes

a locking pawl means for forming on a front end position of the locking member means and fitting into a locking ditch formed on the communication apparatus,

a guide part means for forming on a rear end position of the locking member means, and

a rocking pin means for attaching at a position between the guide part means and the locking pawl means;

a locking lever means which includes

a lock releasing pawl means for forming on a front end position of the locking lever means and fits the guide part means, and

a finger stopping part means for forming on a rear end position of the locking lever means and has a ring shape, wherein the locking lever means is energized in the forward direction by a spring; and

a handle means which includes

a grip part means for having a shape of a ring, wherein the handle means is fixed on a base which is a main part means of the optical module; and

wherein

the grip part means has the ring shape which is larger adequately in size than the finger stopping part means, and protects the finger stopping part means.

7. The locking mechanism of the optical module according to claim 6, wherein

the guide part means includes a virtually triangular pole projecting in a width direction from an end area of the locking lever means, wherein

the triangular pole has one surface, which is parallel with a moving surface of the locking lever means, and has a guide surface, which inclines a downward direction to the moving surface, and

the lock releasing pawl means includes a slide surface opposite to the guide surface;

wherein

the locking member means rocks around the rocking pin means to make the locking pawl means left from the locking ditch when the slide surface being guided along the guide surface according to the locking lever means, which is moved in the backward direction.

8. The locking mechanism of the optical module according to claim 6, wherein

the locking lever means includes a lock holding part means at a position apart from the guide part means by a predetermined distance in the backward direction, and wherein

the lock holding part means touches a rear end of the locking member means to restrain the locking member means from rocking when the locking lever means is moved in the forward direction by force of the spring.

9. The locking mechanism of the optical module according to claim 8, wherein

the lock holding part means is a tapered surface.

10. The locking mechanism of the optical module according to claim 6, wherein

the locking member means is formed by the sheet metal work.
