Combined pluggable optical transceiver and latch-release sleeve

Description

This article is a combined pluggable optical transceiver and latch-release sleeve, used for optical communication, and including an optical transmitter and an optical receiver that are integrally formed. The combined pluggable optical transceiver and latch-release sleeve has a latch mechanism that is plugged to a network apparatus to serve as a retainer when this article is installed on the network apparatus. The latch mechanism connected to a latch-release sleeve can be released by pulling the latch-release sleeve to the forward direction, so that this article can be detached from the network apparatus. Respective corners of the latch-release sleeve are formed to have a round shape, so that the latch-release sleeve can be easily hold along omni-direction, namely, vertical and horizontal directions. Upper and lower surfaces of the latch-release sleeve that are often held by a user are provided with plural grooves with a constant pitch to prevent the user's fingers from being slipped. Further, a height of the latch-release sleeve is slowly increased from a main body side to a front side thereof, such that a holding force can be easily transmitted to the latch mechanism. Still further, the latch-release sleeve is provided with a stopper for limiting a front position thereof with respect to an optical transceiver housing, to avoid an application of an excessive force being to the latch mechanism.

FIG. 1 is an enlarged top, front and right side perspective view of a combined pluggable optical transceiver and latch-release sleeve showing our new design;

FIG. 2 is a front view thereof;

FIG. 3 is a back view thereof;

FIG. 4 is a right side view thereof;

FTG. 5 is a left side view thereof;

FIG. 6 is a top view thereof;

FIG. 7 is a bottom view thereof;

FIG. 8 is an enlarged top, front and right side perspective view of a combined pluggable optical transceiver and latch-release sleeve in a state where a latch is released showing an alternate usage condition;

FIG. 9 is a front view thereof;

FIG. 10 is a back view thereof;

FIG. 11 is a right side view thereof;

FIG. 12 is a left side view thereof;

FIG. 13 is a top view thereof;

In FIGS. 6 and 13, small circles shown at two points on a rear portion of the optical transceiver housing and an outer circle of a double circle shown at one point on a front portion of the optical transceiver housing are holes.

In FIGS. 7 and 14, small circles shown at two points on the rear portion, one point on a front-center portion, and one point on a center portion of the optical transceiver housing are holes. Further, in FIGS. 7 and 14, a rectangular concave portion with a depth of about 0.1 mm is formed at the center portion along a longitudinal direction.

The broken line showing in the figure drawings is included for illustrative purposes only and forms no part of the claimed design.
