Abstract

A pluggable optical transceiver module for being plugged in a housing is provided. The housing has a cover and an elastic piece, and the cover has an accommodating space. One end of the elastic piece is connected to the cover while the other end has a first fastening portion. The first fastening portion is located on one side of the accommodating space. The pluggable optical transceiver module comprises a base and a sliding member. The base comprises a base body and a second fastening portion. The base body has a guide surface, and the second fastening portion is next to the guide surface. The base is for being plugged in the accommodating space, and the second fastening portion is fastened with the first fastening portion. The sliding member comprises a body section and a push section connected to each other. The body section is slidably disposed on the base.

First claim

What is claimed is:

1. A pluggable optical transceiver module for being received within a housing, the housing having a cover and an elastic piece, the cover having an accommodating space, one end of the elastic piece being connected to the cover and the other end having a first fastening portion, the first fastening portion being located on one side of the accommodating space, and the pluggable optical transceiver module comprising:
a base comprising a base body and a second fastening portion, the base body having a guide surface, the base being configured to be received within the accommodating space; and
a sliding member comprising a body section, a reset portion, and an abutting section, the body section being slidably disposed on the base such that the sliding member has a fastening position and a release position, the reset portion being positioned within an opening extending through the body section such that the reset portion urges the sliding member towards the fastening position when in the release position, wherein,
when the sliding member is located at the fastening position, the abutting section is separated from the elastic piece such that the first fastening portion engages the second fastening portion; and
when the sliding member is at the release position, the abutting section engages the elastic piece, causing the second fastening portion to separate from the first fastening portion.

2. The pluggable optical transceiver module according to claim 1 , further comprising a cover plate installed in the base body of the base, wherein the sliding member is between the base body and the cover plate.

3. The pluggable optical transceiver module according to claim 1 , wherein the base further comprises a pressed block, the pressed block is located on the base, wherein one end of the reset portion is connected to the body section while the other end abuts on the pressed block of the base for making the sliding member be at the fastening position normally.

4. The pluggable optical transceiver module according to claim 3 , wherein one side of the reset portion away from the body section comprises two abutting blocks both abutting on the pressed block.

5. The pluggable optical transceiver module according to claim 4 , wherein the reset portion and the body section are integrally formed.

6. The pluggable optical transceiver module according to claim 5 , wherein the material of the sliding member is plastic, and the type of the plastic is Nylon 66.

7. The pluggable optical transceiver module according to claim 3 , wherein the sliding member further comprises a pull section, the sliding member further comprises a flexure section located between the body section and the abutting section, and the base section is between the flexure section and the pull section.

8. The pluggable optical transceiver module according to claim 1 , wherein the base body has a bottom surface and a concave portion formed inwardly from the bottom surface, the base further comprises two side walls located on the concave portion, the two side walls respectively have a sliding groove, opposing sides of the body section each have a sliding block respectively and the two sliding blocks are located in the two sliding groove in a slidable manner.

9. The pluggable optical transceiver module according to claim 1 , wherein the concave portion has at least one limit groove, the body section has a limit block, and the limit block is located in the limit groove in a slidable manner.

10. The pluggable optical transceiver module according to claim 1 , wherein the second fastening portion has a top surface, the guide surface has a fastening end and a release end, the vertical distance from the fastening end to the top surface is greater than the vertical distance from the release end to the top surface, when the sliding member is located at the release position, the abutting section is located on the release end of the guide surface and abuts on the elastic piece for separating the second fastening portion from the first fastening portion.

11. The pluggable optical transceiver module according to claim 10 , wherein the abutting section is a protruding block, the width of the protruding block ranges from the vertical distance from the fastening end to the top surface to the vertical distance from the release end to the top surface.

12. The pluggable optical transceiver module according to claim 1 , wherein the sliding member further comprises a flexure section located between the body section and the abutting section, and the abutting section is configured for moving relative to the body section depending on the elastic deformation capacity of the flexure section.

13. The pluggable optical transceiver module according to claim 1 , wherein the base body has at least one guide groove, and the at least one guide groove is located on one side of the second fastening portion.

14. The pluggable optical transceiver module according to claim 13 , wherein the number of the guide grooves is two, the second fastening portion is between the two guide grooves, the number of the abutting sections is two, the abutting sections are protruding blocks, when the sliding member is located at the fastening position, the two abutting sections are inside the two guide grooves, and when the sliding member is at the release position, the two abutting sections are guided by the two guide surfaces to together abut on the elastic piece, for separating the second fastening portion from the first fastening portion.

15. The pluggable optical transceiver module according to claim 13 , wherein the base further comprises a circuit inside the base body.
