TWI810912B - Case structure with latch mechanism and fiber optical transceiver having the same - Google Patents

Abstract

The present invention discloses a case structure with latch mechanism for use in a fiber optical transceiver. The case structure comprises: a base, a cover member, an accommodating member, a connection member, and pull member, and a latch unit, of which the cover member and the based is combined to become a housing having a front opening and a rear opening. Moreover, the accommodating member is disposed at the rear opening, and the latch unit is accommodated in the accommodating member. Particularly, the latch unit has a latch rod exposed out of the accommodating member and the cover member, so as to latch the connection member on the cover member. It is worth further explaining that, in case the latch rod is exposed out of the cover member, it fails to pull the connection member to move by applying a force to the pull member. In such case, the connection member and the pull member are both latched by the latch unit. On the contrary, by pressing the latch rod to be below the cover member, it succeeds to pull the connection member to move by applying a force to the pull member.

Description

Housing structure with locking mechanism and optical fiber with the housing structure transceiver

The present invention relates to the technical field of fiber optic transceivers, in particular to a casing structure with a locking mechanism applied as a device casing of a fiber optic transceiver.

It is known that an optical fiber transceiver is also called an optical-to-electrical converter, and its function is to realize mutual conversion between optical signals and electrical signals. Generally, a fiber optic transceiver has an electrical connection side and an optical connection side, wherein the electrical connection side is used to connect an Ethernet connector of a network device (such as a POE device or a network switching device), and the optical connection side The connecting side is used for connecting an optical fiber cable. According to this setting, the optical fiber transceiver can convert the electrical signal into an optical signal, and then transmit it through the optical fiber cable. At the same time, the optical fiber transceiver can also convert the optical signal into an electrical signal, and then transmit the electrical signal to the network device.

Network equipment engineers must know that the maximum transmission distance of a general network line is 100 meters, so multiple POE devices and optical fiber cables must be used together when building a large-scale network (such as a large-scale network monitoring system). Different from network cables, the transmission distance of single-mode optical fiber is more than 10 kilometers, while the transmission distance of multi-mode optical fiber can reach up to 2 kilometers. exist When using POE devices and optical fibers, optical fiber transceivers become an indispensable and important electronic component.

For example, Taiwan Patent No. M618563 discloses an optical fiber transceiver. According to the disclosure of Taiwan's new patent number M618563, the optical fiber transceiver includes: a housing, a circuit board disposed in the housing, an electronic chip and necessary electronic components disposed on the circuit board, disposed on the circuit An electrical connection unit on one side of the board, an optical connection unit on the other side of the circuit board, and a pull tab.

FIG. 1 shows a perspective view of a conventional optical fiber transceiver. As shown in Figure 1, the conventional optical fiber transceiver 1a includes: a base 11a, a cover 12a, and a handle unit, wherein the cover 12a is combined with the base 11a to form a front opening and a rear A shell with an opening. It is worth noting that the handle unit includes a connecting piece 14a and a handle 15a, wherein the connecting piece 14a has two first joint sections (Segment) 141a respectively connected to the side of the cover 12a, and the A second combining section 142a connected to the two first combining sections 141a, and two third combining sections 143a connected to the second combining section 142a. In more detail, the second combining section 142a fits on the upper surface of the cover 12a, and the handle 15 has a handle tongue 151a and two fourth combining sections 152a respectively connected to the two third combining sections 143a . Moreover, in the prior art, a fastening portion 1411a is usually formed at the end of the first combining section 141a.
